Description

L'invention a trait aux dispositifs de connexion pour câble coaxial.The invention relates to connection devices for coaxial cable.

On sait qu'un tel dispositif doit, d'une part, permettre un maintien convenable du câble coaxial, et, d'autre part, assurer, de manière distincte, un premier contact électrique avec la tresse métallique constituant usuellement le blindage interne d'un tel câble coaxial et un deuxième contact électrique avec son âme centrale conductrice.We know that such a device must, on the one hand, allow a maintenance of the coaxial cable, and, on the other hand, to ensure, in a distinct way, a first electrical contact with the metal braid usually constituting the internal shielding of such a coaxial cable and a second electrical contact with its central conducting core.

On connaít déjà, par la demande de brevet français 2 787 936 appartenant à la demanderesse, un tel dispositif de connexion, présentant une alvéole propre à un engagement direct d'une extrémité, au préalable en partie dénudée, d'un câble coaxial à raccorder ; présentant, dans ladite alvéole, une lame de contact allongée suivant la même direction que l'alvéole, adaptée à embrocher le câble coaxial entre sa gaine extérieure et son blindage ; présentant une came, montée rotative autour d'un axe de rotation orienté parallèlement à la direction de l'alvéole, laquelle came est munie d'une nervure de serrage saillante dont la distance de crête par rapport à l'axe de rotation de la came est variable ; et présentant une borne de contact avec laquelle l'âme centrale du câble coaxial est destinée à venir en prise.We already know, by the French patent application 2 787 936 owned by the applicant, such a connection device, having a cell clean to a direct engagement of an end, in advance partly denuded, of a coaxial cable to be connected; having, in said cell, a blade contact elongated in the same direction as the cell, adapted to skewer the coaxial cable between its outer sheath and its shielding; presenting a cam, rotatably mounted about an axis of rotation oriented parallel to the direction of the cell, which cam is provided with a protruding clamping rib whose peak distance from the axis of rotation of the cam is variable; and having a contact terminal with which the central core of the coaxial cable is intended to come into play.

Avec un tel dispositif de connexion, seule est dénudée l'âme centrale du câble coaxial. Il n'y a pas, contrairement aux dispositifs de connexion conventionnels, à opérer, en arrière de la partie dénudée de l'âme centrale, un dénudage de la tresse, relativement délicat à réaliser puisqu'il consiste à enlever la seule gaine extérieure.With such a connection device, only the central core of the coaxial cable. There is no unlike connection devices conventional, to operate, behind the bare part of the central core, a stripping the braid, relatively difficult to achieve since it consists of removing the only outer sheath.

Une fois que le câble, ainsi dénudé, est embroché sur la lame de contact, le câble est verrouillé avec la came, en faisant tourner celle-ci d'un quart de tour à l'aide d'un tournevis. La nervure de serrage de la came vient alors porter contre la gaine isolante extérieure du câble coaxial, laquelle gaine est ainsi pincée entre la nervure de serrage et la lame de contact, ce qui suffit à un maintien convenable du câble coaxial.Once the cable, thus stripped, is skewered on the blade of contact, the cable is locked with the cam, turning it a quarter turn with a screwdriver. The clamping rib of the cam then comes to wear against the outer insulating sheath of the coaxial cable, which sheath is thus pinched between the clamping rib and the contact blade, which is sufficient to maintain suitable coaxial cable.

L'invention vise à améliorer ce genre de dispositif, notamment en ce qui concerne ses conditions d'utilisation.The aim of the invention is to improve this kind of device, particularly with regard to regards its conditions of use.

Elle propose à cet effet un dispositif de connexion pour câble coaxial, présentant une alvéole propre à un engagement direct d'une extrémité, au préalable en partie dénudée, d'un câble coaxial à raccorder ; présentant, dans ladite alvéole, une lame de contact allongée suivant la même direction que l'alvéole, adaptée à embrocher ledit câble coaxial entre sa gaine extérieure et son blindage ; et présentant une borne de contact avec laquelle l'âme centrale dudit câble coaxial est destinée à venir en prise ; caractérisé en ce qu'il comporte un socle, auquel appartient ladite lame de contact, et un capot, adapté à être fixé au socle dans une position fermée dudit dispositif, lequel capot comporte au moins un organe de retenue se trouvant à proximité immédiate de ladite lame de contact dans ladite position fermée, lequel organe de retenue est adapté, dans ladite position fermée, à agripper à l'opposé de ladite lame ladite gaine isolante extérieure d'un câble embroché sur ladite lame.It proposes for this purpose a connection device for coaxial cable, having a cell capable of direct engagement from one end to the previously stripped, of a coaxial cable to be connected; presenting, in said cell, an elongate contact blade in the same direction as the cell, adapted to plug said coaxial cable between its outer sheath and its shielding; and having a contact terminal with which the central core of said coaxial cable is intended to come into engagement; characterized in that it comprises a base, to which belongs said contact blade, and a cover adapted to be fixed to the base in a closed position of said device, which cover comprises at least one retaining member in the immediate vicinity of said contact blade in said closed position, which retaining member is adapted, in said closed position, to grip opposite said blade said insulating sheath outer of a cable sockets on said blade.

Tout comme avec le dispositif antérieur susmentionné, il n'y a pas à dénuder la tresse du blindage du câble coaxial avant l'engagement dans l'alvéole, lequel s'effectue bien entendu en position ouverte du dispositif de connexion, où le ou les organes(s) de retenue sont à l'écart de la lame de contact.As with the previous device mentioned above, there is no need for strip the shielding braid of the coaxial cable before engagement in the cell, which is of course in the open position of the connection device, where the or the retainer (s) are away from the contact blade.

Ensuite, la simple fermeture de ce dispositif y verrouille le câble grâce à l'agrippage opéré sur la gaine isolante extérieure par le ou les organe(s) de retenue du capot.Then, simply closing this device locks the cable through the gripping performed on the outer insulating sheath by the retaining organ (s) hood.

La mise en oeuvre de l'opération de raccordement d'un câble coaxial à un dispositif de connexion selon l'invention est ainsi particulièrement simple et commode.The implementation of the operation of connecting a coaxial cable to a connection device according to the invention is thus particularly simple and dresser.

En outre, la prévision d'un ou plusieurs organe(s) de retenue directement sur le capot permet au dispositif de connexion selon l'invention d'être obtenu avec un nombre réduit de composants et/ou d'être particulièrement compact.In addition, the prediction of one or more restraint organ (s) directly on the hood allows the connection device according to the invention to be obtained with a reduced number of components and / or to be particularly compact.

Selon des caractéristiques préférées de mise en oeuvre, pour des raisons de simplicité et de commodité :

  • ledit organe de retenue est une griffe présentant une extrémité pointue ; et/ou
  • ledit dispositif comporte deux dits organes de retenue formés chacun par une griffe présentant une extrémité pointue ; et éventuellement
  • lesdites deux griffes sont centrées sur un plan de symétrie longitudinal que présente ledit capot ; et/ou

The description of the invention will now be continued by the description of an exemplary embodiment, given below by way of illustration and not limitation, with reference to the accompanying drawings. On these:
  • Figure 1 is a perspective view of a device according to the invention which is connected to a coaxial cable, this device forming a motor for a television or FM wall radio;

  • Figure 6 is a view similar to Figure 5 for a variant of the device where the connection tip is F type rather than female IEC.

Le dispositif 1 illustré sur les figures 1 à 5 comporte un socle 2 et un capot 3. Il est prévu pour être raccordé à un câble coaxial 4, ici un câble de distribution des signaux de télévision et/ou de radio FM.The device 1 illustrated in FIGS. 1 to 5 comprises a base 2 and a cover 3. It is intended to be connected to a coaxial cable 4, here a cable of distribution of television and / or FM radio signals.

Un tel câble comporte une gaine extérieure 5 en matière plastique isolante, une tresse 6 faite de fins fils métalliques conducteurs, une gaine intérieure 7 en matière plastique isolante et une âme centrale 8 formée par un fil métallique conducteur relativement rigide. La gaine intérieure 7 entoure étroitement l'âme 8, la tresse 6 entoure étroitement la gaine intérieure 7 tandis que la gaine extérieure 5 entoure étroitement la tresse 6.Such a cable comprises an outer sheath 5 made of plastic insulation, a braid 6 made of fine conductive wire, an inner sheath 7 made of insulating plastic and a central core 8 formed by a metal wire relatively rigid conductor. The inner sheath 7 tightly surrounds the core 8, the braid 6 closely surrounds the inner sheath 7 while the outer sheath 5 tightly surrounds the braid 6.

Le capot 3 et le câble de distribution 4 sont prévus pour être disposés du côté interne de la prise tandis que du côté externe il est prévu un embout 9 pour le branchement d'une extrémité d'un cordon servant à relier la prise à un appareil de réception de la télévision et/ou de la radio FM.The cover 3 and the distribution cable 4 are designed to be arranged on the inner side of the socket while on the outer side is provided a tip 9 for connecting one end of a cord used to connect the plug to a device receiving television and / or FM radio.

Comme on le voit plus particulièrement sur la figure 2, le socle 2 de la prise 1 comporte un corps 10, un insert 11 et une borne de contact 12. As can be seen more particularly in FIG. 2, the base 2 of the socket 1 comprises a body 10, an insert 11 and a contact terminal 12.

Le corps 10 est en métal conducteur moulé. Il comporte une platine 15 présentant, du côté que l'on voit en bas sur les dessins, une face plate 16 (figure 5) de laquelle saille un fût tubulaire 17 appartenant à l'embout 9.The body 10 is made of molded conductive metal. It has a turntable 15 having, on the side shown below in the drawings, a flat face 16 (FIG. 5) from which protrudes a tubular shaft 17 belonging to the tip 9.

La platine 15 a un contour rectangulaire dont la largeur correspond à une dimension prédéterminée commune à une série d'appareils pour installations électriques, par exemple de l'ordre de 22,5 mm, et dont la longueur est d'environ le double de la largeur.The plate 15 has a rectangular outline whose width corresponds to a predetermined dimension common to a series of apparatus for installations electrical devices, for example of the order of 22.5 mm, and whose length is about double the width.

Dans la platine 15 est ménagée une ouverture 18 qui forme un prolongement de l'alésage du fût 17.In the plate 15 is formed an opening 18 which forms a extension of the barrel bore 17.

A proximité de l'un des bords transversaux de la platine 15, le corps 10 présente deux charnons 19 en forme de demi-anneau, en saillie par rapport à la face 20 de la platine 15 opposée à la face 16. Les charnons 19 servent à l'articulation du capot 3 vis-à-vis du corps 10, et plus généralement vis-à-vis du socle 2.Near one of the transverse edges of the plate 15, the body 10 has two knuckles 19 in the form of a half-ring projecting from the face 20 of the plate 15 opposite the face 16. The knuckles 19 are used to the articulation of the cover 3 vis-à-vis the body 10, and more generally vis-à-vis the base 2.

De la face 20 de la platine 15 saille également une cage 21, située entre l'ouverture 18 et le bord transversal de la platine 15 opposé à celui où se trouvent les charnons 19. La cage 21 a une largeur qui est d'environ la moitié de la largeur de la platine 15.From the face 20 of the plate 15 also projects a cage 21, located between the opening 18 and the transverse edge of the plate 15 opposite that where are the knuckles 19. The cage 21 has a width that is about half the width of the stage 15.

Sur à peu près la moitié de sa circonférence, à l'opposé de la cage 21, l'ouverture 18 est bordée par une cloison 22 ayant la forme d'un tronçon de gouttière. La cloison 22 est disposée en saillie par rapport à la face 20 de la platine 15.On about half of its circumference, opposite the cage 21, the opening 18 is bordered by a partition 22 having the shape of a section of gutter. The partition 22 is arranged projecting with respect to the face 20 of the plate 15.

Une rainure 23 est ménagée dans la platine 15 en creux par rapport à la face 20.A groove 23 is formed in the plate 15 recessed relative to the face 20.

La rainure 23 a une forme générale rectangulaire. L'un de ses petits côtés est orienté suivant la direction transversale et est disposé à proximité des charnons 19, lesquels sont situés entre la rainure 23 et l'un des bords transversaux de la platine 15. Les deux grands côtés de la rainure 23 sont orientés suivant la direction longitudinale et sont situées à proximité des bords latéraux de la platine 15. L'autre petit côté de la rainure 23 est orienté suivant la direction transversale et est disposé à proximité du bord transversal de la platine 15 adjacent à la cage 21, ce petit côté n'étant pas continu mais formé par deux tronçons situés de part et d'autre de la cage 21. The groove 23 has a generally rectangular shape. One of his little ones sides is oriented in the transverse direction and is arranged near the knuckles 19, which are located between the groove 23 and one of the transverse edges of the plate 15. The two long sides of the groove 23 are oriented according to the longitudinal direction and are located near the side edges of the plate 15. The other small side of the groove 23 is oriented in the transverse direction and is disposed near the transverse edge of the plate 15 adjacent to the cage 21, this small side not being continuous but formed by two sections located on the side and other of the cage 21.

Une nervure 24, saillant elle aussi de la face 20 de la platine 15, est disposée entre la nervure 23 et la cloison 22. La nervure 24 longe le petit côté de la rainure 23 situé à proximité des charnons 19 et une partie de chacun des deux grands côtés de la rainure 23.A rib 24, also protruding from the face 20 of the plate 15, is disposed between the rib 23 and the partition 22. The rib 24 runs along the short side of the groove 23 located near the knuckles 19 and part of each of the two long sides of the groove 23.

Au-delà de la cloison 22, la nervure 24 se prolonge, le long de chaque grand côté de la rainure 23, environ jusqu'à mi-longueur de la cage 21, par un muret droit 25 disposé à l'écart de la cage 21.Beyond the partition 22, the rib 24 extends along each large side of the groove 23, about halfway up the length of the cage 21, by a straight wall 25 disposed away from the cage 21.

Chaque coin de la rainure 23 situé de part et d'autre de la cage 21 est longé par un muret 26 en cornière.Each corner of the groove 23 located on either side of the cage 21 is along a wall 26 in angle.

La cage 21 délimite une alvéole 27 à contour général cylindrique de diamètre correspondant au diamètre externe du câble 4 et d'axe 51 situé dans le plan de symétrie longitudinal du corps 10 et incliné vers la platine 15 et vers l'ouverture 18, ainsi qu'on le voit plus particulièrement sur la figure 5.The cage 21 delimits an alveolus 27 with a cylindrical general contour of diameter corresponding to the outer diameter of the cable 4 and 51 axis located in the longitudinal plane of symmetry of the body 10 and inclined towards the plate 15 and towards the opening 18, as seen more particularly in Figure 5.

Entre la platine 15 et l'alvéole 27, la cage 21 présente un berceau plein 28 délimité du côté de l'alvéole 27 par une surface hémicylindrique.Between the plate 15 and the cell 27, the cage 21 has a full cradle 28 delimited on the side of the cell 27 by a hemicylindrical surface.

Du côté du bord transversal de la platine 15 opposé aux charnons 19, le berceau 28 se raccorde à une arche 29 dont la surface interne est hémicylindrique et prolonge la surface interne du berceau 28. Ainsi, la cage 21 présente, le long du bord transversal de la platine 15 opposé aux charnons 19, un contour cylindrique continu délimitant une bouche d'entrée dans l'alvéole 27.On the side of the transverse edge of the plate 15 opposite the knuckles 19, the cradle 28 connects to an arch 29 whose inner surface is semi-cylindrical and extends the inner surface of the cradle 28. Thus, the cage 21 presents, along the transverse edge of the plate 15 opposite the knuckles 19, a cylindrical contour continuously delimiting an inlet mouth in the cell 27.

A l'opposé de l'arche 29, c'est à dire du côté de l'ouverture 18, la cage 21 comporte une arche 30 similaire à l'arche 29.At the opposite of the arch 29, that is to say on the side of the opening 18, the cage 21 has an arch 30 similar to the arch 29.

L'arche 30 porte une lame de contact 31 ayant globalement la forme d'un ongle.The arch 30 carries a contact blade 31 having generally the shape of a nail.

Plus précisément, la lame 31 présente un profil en arc dont le rayon correspond à celui de la tresse 6 du câble 4. La lame 31 est disposée concentriquement à l'alvéole 27. La face concave de la lame 31 regarde le berceau 28 tandis que sa face convexe regarde les arches 29 et 30.More specifically, the blade 31 has an arcuate profile whose radius corresponds to that of the braid 6 of the cable 4. The blade 31 is arranged concentrically to the cell 27. The concave face of the blade 31 looks at the cradle 28 while its convex face looks at the arches 29 and 30.

Le rattachement entre la lame 31 et l'arche 30 se fait par un pontet 32 s'étendant entre l'arche 30 et l'extrémité de la lame 31 située du côté de l'ouverture 38 (extrémité proximale). The connection between the blade 31 and the arch 30 is by a bridge 32 extending between the arch 30 and the end of the blade 31 located on the side of the opening 38 (proximal end).

Comme on le voit sur la figure 5, la lame 31 est légèrement plus longue que le reste de la cage 21, son extrémité distale (extrémité opposée au pontet 32) saillant légèrement à l'extérieur au-delà de l'arche 29.As seen in Figure 5, the blade 31 is slightly longer than the rest of the cage 21, its distal end (opposite end to the bridge 32) protruding slightly outside the arch 29.

L'extrémité distale de la lame 31 est conformée en pointe, c'est-à-dire que sa largeur, et plus précisément son extension angulaire, se réduit progressivement vers cette extrémité. La tranche de cette dernière est par ailleurs effilée, c'est-à-dire que la lame 31 présente une épaisseur qui se réduit vers son extrémité distale au voisinage de celle-ci.The distal end of the blade 31 is shaped in point, that is to say that its width, and more precisely its angular extension, is reduced gradually towards this end. The portion of the latter is tapered, that is to say that the blade 31 has a thickness which is reduced to its distal end in the vicinity thereof.

Comme on le voit plus particulièrement sur la figure 4, la lame 31 présente, à l'opposé de la platine 15, c'est-à-dire du côté convexe, un méplat 33 s'étendant entre l'arche 29 et l'arche 30.As can be seen more particularly in FIG. 4, the blade 31 present, opposite the plate 15, that is to say on the convex side, a flat part 33 extending between the arch 29 and the arch 30.

Au centre du méplat 33 est ménagée une rainure 34 s'étendant suivant la direction longitudinale. La rainure 34 présente un profil en V.In the center of the flat part 33 is formed a groove 34 extending according to the longitudinal direction. The groove 34 has a V-shaped profile.

On observera que la portion de la lame 31 située entre les arches 29 et 30 est accessible depuis l'extérieur de la cage 21 tant à l'opposé du berceau 28 que latéralement, de part et d'autre.It will be observed that the portion of the blade 31 situated between the arches 29 and 30 is accessible from outside the cage 21 as opposed to the cradle 28 than laterally, on both sides.

L'insert 11 est en matière plastique moulée isolante.The insert 11 is made of insulating molded plastic.

Il comporte un pied 35, une tête 36, un plastron 37, deux bras 38 et deux pattes d'encliquetage 39.It comprises a foot 35, a head 36, a plastron 37, two arms 38 and two latching lugs 39.

Le pied 35 et la tête 36 sont orientés suivant la direction axiale et sont disposés dans le prolongement l'un de l'autre.The foot 35 and the head 36 are oriented in the axial direction and are arranged in the extension of one another.

Comme on le voit plus particulièrement sur les figures 4 et 5, la tête 36 et le plastron 37 délimitent un compartiment 40 dans lequel débouche l'alésage du pied 35. A l'opposé du plastron 37, la tête 36 délimite un autre compartiment 41. Entre le compartiment 40 et le compartiment 41 est ménagée un passage 42 disposé centralement.As can be seen more particularly in FIGS. 4 and 5, the head 36 and the plastron 37 delimit a compartment 40 into which the bore of the foot 35. At the opposite of the front plate 37, the head 36 delimits another compartment 41. Between the compartment 40 and the compartment 41 is formed a passage 42 centrally arranged.

Dans le plastron 37 est ménagé un trou 43 offrant un passage entre le compartiment 40 et l'extérieur.In the plastron 37 is formed a hole 43 providing a passage between the compartment 40 and the outside.

La passage 42 et le trou 43 sont centrés sur le plan de symétrie longitudinal de l'insert 11.The passage 42 and the hole 43 are centered on the plane of symmetry longitudinal of the insert 11.

Les bras 38 sont orientés suivant la direction longitudinale. Ils prennent chacun racine par une extrémité à la jonction entre le pied 35, la tête 36 et le plastron 37. Ils saillent du plastron 37 du côté opposé au compartiment 41. The arms 38 are oriented in the longitudinal direction. They take each root at one end at the junction between the foot 35, the head 36 and the Bib 37. They protrude plastron 37 on the opposite side to compartment 41.

L'écart entre les bras 38 correspond sensiblement à la largeur de la cage 21.The gap between the arms 38 corresponds substantially to the width of the cage 21.

Les pattes d'encliquetage 39 sont orientées suivant la direction axiale. Elles prennent chacune racine latéralement sur l'un des bras 38, à l'opposé du plastron 37, du côté externe. Chaque patte 39 saille du bras 38 auquel il est rattaché, du même côté que la tête 36 et le plastron 37.The latching tabs 39 are oriented in the axial direction. They each take root laterally on one of the arms 38, opposite the plastron 37, on the external side. Each leg 39 protrudes from the arm 38 to which it is attached on the same side as the head 36 and the plastron 37.

A l'extrémité distale de chacun des bras 39 se trouve un cran 44.At the distal end of each arm 39 is a notch 44.

La borne de contact 12 est en feuillard métallique conducteur conformé relativement flexible.The contact terminal 12 is made of shaped conductive metal strip relatively flexible.

La borne 12 est orientée suivant la direction axiale. Elle comporte une queue 45, une lyre 46 et un pontet 47 de raccordement entre la queue 45 et la lyre 46.Terminal 12 is oriented in the axial direction. It has a tail 45, a lyre 46 and a bridge 47 connecting the tail 45 and the lyre 46.

La queue 45 est globalement tubulaire et présente sur toute sa longueur une fente 48 orientée suivant la direction axiale.The tail 45 is generally tubular and present throughout its length a slot 48 oriented in the axial direction.

La lyre 46 comporte deux lèvres 49 à profil globalement en V. Les sommets des lèvres 49 sont orientés suivant la direction axiale et sont sensiblement alignées avec la fente 48.The lyre 46 has two lips 49 with a generally V profile. vertices of the lips 49 are oriented in the axial direction and are substantially aligned with slot 48.

A l'opposé des lèvres 49, la lyre 46 présente un trou 50 (figure 5).In contrast to the lips 49, the lyre 46 has a hole 50 (FIG. 5).

La mise en place de l'insert 11 dans le corps 10 se fait par simple emboítement.The introduction of the insert 11 in the body 10 is by simple nesting.

A l'état assemblé, le pied 35 est logé dans le fût 17 et dans l'ouverture 18, la tête 36 est entourée par la cloison 22 et par la cage 21 avec le plastron 37 qui est disposé contre l'arche 30 tandis que les bras 38 sont chacun disposés entre la cage 21 et les murets 25 et 26 contre la face 20. La racine des pattes d'encliquetage 39 est disposée entre les murets 25 et 26 tandis que les crans 44 sont disposés au niveau de l'espace existant entre les arches 29 et 30.In the assembled state, the foot 35 is housed in the barrel 17 and in the opening 18, the head 36 is surrounded by the partition 22 and the cage 21 with the plastron 37 which is arranged against the arch 30 while the arms 38 are each arranged between the cage 21 and the walls 25 and 26 against the face 20. The root of the legs latch 39 is disposed between the walls 25 and 26 while the notches 44 are arranged at the level of the existing space between the arches 29 and 30.

La mise en place de la borne de contact 12 dans le corps 2, et plus précisément dans l'insert 11, s'effectue également par emboítement. A l'état assemblé (figures 4 et 5) la lyre 46 est disposée dans le compartiment 40, le pontet 47 et une partie de la queue 45 sont disposés dans l'alésage du pied 35, le reste de la queue 45 saillant du pied 35 dans le fût 17.The establishment of the contact terminal 12 in the body 2, and more precisely in the insert 11, is also carried out by interlocking. In the state assembled (Figures 4 and 5) the lyre 46 is disposed in the compartment 40, the trigger guard 47 and a part of the tail 45 are arranged in the bore of the foot 35, the rest the tail 45 protruding from the foot 35 in the drum 17.

Les lèvres 49 de la lyre 46 sont disposées en regard du plastron 37 et sont centrées vis-à-vis du trou 43. The lips 49 of the lyre 46 are arranged facing the front plate 37 and are centered with respect to the hole 43.

Le passage 42, le trou 50, les lèvres 49 et le trou 43 sont centrés selon le plan de symétrie longitudinal du corps 2 avec les trous 43 et 50 qui sont alignés avec l'alvéole 27, c'est-à-dire centrés sur le même axe 51 (figure 5).The passage 42, the hole 50, the lips 49 and the hole 43 are centered according to the longitudinal plane of symmetry of the body 2 with the holes 43 and 50 which are aligned with the cell 27, that is to say, centered on the same axis 51 (Figure 5).

Le capot 3 est en métal conducteur moulé.The cover 3 is made of molded conductive metal.

Il a globalement une forme de caisson parallélépipédique.It generally has a parallelepipedic box shape.

La tranche de sa paroi latérale présente sensiblement la même conformation que la rainure 23 du corps 10.The edge of its side wall has substantially the same conformation that the groove 23 of the body 10.

A proximité de l'un des petits côté de la tranche de la paroi latérale, le capot 3 présente, du côté extérieur, deux broches 55 orientées suivant la direction transversale et alignées. Chaque broche 55 saille d'une nervure 56 saillant elle-même de la paroi latérale du capot 3, et plus précisément d'un tronçon de cette paroi latérale orienté suivant la direction transversale.Near one of the small side of the edge of the side wall, the cover 3 has, on the outside, two pins 55 oriented in the direction transversal and aligned. Each pin 55 protrudes from a protruding rib 56 itself of the side wall of the hood 3, and more precisely of a section of this side wall oriented in the transverse direction.

Le tronçon opposé de la paroi latérale, c'est-à-dire l'autre tronçon de cette paroi orienté suivant la direction transversale, présente une ouverture centrale 57 dont le contour correspond à celui de la cage 21 au niveau de l'arche 29.The opposite section of the side wall, that is to say the other section of this wall oriented in the transverse direction, has an opening central 57 whose contour corresponds to that of the cage 21 at the level of the arch 29.

Chacun des tronçons de la paroi latérale du capot 3 orienté suivant la direction longitudinale présente une fenêtre 58 à proximité du tronçon transversal où est ménagée l'ouverture 57.Each of the sections of the side wall of the hood 3 oriented according to the longitudinal direction has a window 58 near the transverse section where is the opening 57.

Les fenêtres 58 ont sensiblement la même largeur que les pattes d'encliquetage 39. Elles s'étendent d'une surface 59 parallèle à la tranche de la paroi latérale jusqu'à la paroi de fond du capot 3, dans laquelle d'ailleurs les fenêtres 58 sont partiellement ménagées.The windows 58 have substantially the same width as the legs 39. They extend from a surface 59 parallel to the edge of the lateral wall up to the bottom wall of the hood 3, in which, moreover, the windows 58 are partially arranged.

De la face interne 60 de la paroi de fond du capot 3, saille une nervure 61 orientée suivant la direction longitudinale et disposée centralement. La nervure 61 a la même largeur qu'une encoche 62 pratiquée dans la cloison 22 du corps 10.From the inner face 60 of the bottom wall of the cover 3, protrudes a rib 61 oriented in the longitudinal direction and arranged centrally. The rib 61 has the same width as a notch 62 made in the partition 22 of the body 10.

De la face 60 de la paroi de fond du capot 3 saille également une nervure 63 à profil en U. La portion incurvée de la nervure 63 présente un contour externe correspondant sensiblement au contour interne de la cloison 22.From the face 60 of the bottom wall of the hood 3 also projects a rib 63 with a U-profile. The curved portion of the rib 63 has an outline outermost substantially corresponding to the inner contour of the partition 22.

Une autre nervure 64, légèrement incurvée mais orientée globalement suivant la direction transversale, saille de la face 60 et se raccorde à chaque extrémité à l'une des extrémités de la nervure 63. Another rib 64, slightly curved but oriented globally in the transverse direction, protrudes from face 60 and connects to each end at one end of rib 63.

La distance entre l'extrémité de la nervure 61 située à côté de la nervure 63 et la nervure 64 correspond à la distance entre l'encoche 62 et la tranche du plastron 37.The distance between the end of the rib 61 located next to the rib 63 and the rib 64 corresponds to the distance between the notch 62 and the edge of the plastron 37.

Une nervure 65 en forme d'arche, orientée suivant la direction transversale, saille de la face 60 et est disposée contre la nervure 64, à l'opposé de la nervure 63.A 65 arch-shaped rib, oriented in the direction transverse, protrudes from the face 60 and is disposed against the rib 64, as opposed to the rib 63.

Deux griffes 66 présentant chacune une extrémité pointue saillent également de la paroi 60. Les griffes 66 sont disposées entre l'ouverture 57 et la nervure 65 et sont centrées sur le plan de symétrie longitudinal du capot 3. De part et d'autre des griffes 66, au même niveau que les fenêtres 58, saillent de la face 60 deux pattes 67.Two claws 66 each having a pointed end protrude wall 66. The claws 66 are disposed between the opening 57 and the rib 65 and are centered on the longitudinal plane of symmetry of the hood 3. Part and other claws 66, at the same level as the windows 58, project from the face 60 two legs 67.

Les faces en regard des pattes 67 ont un profil en V. Elles forment à chaque extrémité, à la jonction avec une face latérale, une arête 68 relativement acérée.The facing faces of the tabs 67 have a V-shaped profile. each end, at the junction with a lateral face, a relative edge 68 sharp.

Le capot 3 présente également, en creux par rapport à la face externe de sa paroi de fond, une rainure 69 (figure 1) dont la largeur correspond sensiblement à celle de l'âme centrale 8 du câble 4. La longueur de la rainure 69 correspond à celle sur laquelle il est nécessaire de dénuder l'âme 8, ainsi qu'expliqué ultérieurement. La rainure 69 offre ainsi à l'utilisateur un gabarit lui permettant de contrôler si la portion dénudée de l'âme 8 présente la longueur requise.The cover 3 also has, hollow relative to the outer face from its bottom wall, a groove 69 (FIG. 1) whose width corresponds substantially to that of the central core 8 of the cable 4. The length of the groove 69 corresponds to the one on which it is necessary to strip the soul 8, as well as explained later. The groove 69 thus offers the user a template him to control whether the stripped portion of the core 8 has the length required.

L'assemblage entre le socle 2 et le capot 3 s'effectue par simple insertion des broches 55 dans les charnons 19.The connection between the base 2 and the cover 3 is made by simple insertion of the pins 55 into the knuckles 19.

La coopération des broches 55 et des charnons 19 procure une articulation entre le socle 2 et le capot 3 suivant un axe de pivotement orienté suivant la direction transversale, lequel axe est situé à proximité du bord transversal de la platine 15 opposé à celui du côté duquel se trouve la bouche d'entrée dans l'alvéole 27.The cooperation of the pins 55 and the knuckles 19 provides a articulation between the base 2 and the cover 3 along a pivot axis oriented in the transverse direction, which axis is near the edge transverse of the plate 15 opposite the one on the side of which is the mouth entrance into the cell 27.

Le capot 3 peut ainsi pivoter vis-à-vis du socle 2 entre la position relevée montrée sur la figure 2 et la position rabattue montrée sur la figure 1.The cover 3 can thus pivot with respect to the base 2 between the position raised shown in Figure 2 and the folded position shown in Figure 1.

On va maintenant décrire comment l'on raccorde un câble coaxial 4 au dispositif de connexion 1. We will now describe how to connect a coaxial cable 4 to connection device 1.

L'extrémité du câble 4 est d'abord entièrement dénudée jusqu'à l'âme centrale 8, sur une longueur prédéterminée correspondant à la longueur de la rainure 69, ainsi que montré sur la figure 2.The end of the cable 4 is first completely stripped to the core 8, a predetermined length corresponding to the length of the groove 69, as shown in Figure 2.

Ensuite, le capot 3 étant relevé, le câble 4 est engagé à force, autant que possible, dans l'alvéole 27 en faisant en sorte que la lame de contact 31 l'embroche entre sa gaine extérieure 5 et sa tresse 6.Then, the hood 3 being raised, the cable 4 is engaged by force, as much as possible, in the cell 27 by ensuring that the contact blade 31 the spit between its outer sheath 5 and its braid 6.

Ce faisant, l'âme centrale 8 du câble 4 passe au travers du trou 43 du plastron 37, s'engage entre les lèvres 49 de la lyre 46 de la borne de contact 12 puis, suivant la longueur de dénudage et la profondeur d'enfoncement du câble 4 dans l'alvéole 27, une portion de l'âme dénudée 8 passe ou non au travers du trou 50 et vient se loger dans le passage 42 et dans le compartiment 41, ainsi que représenté sur la figure 5.In doing so, the central core 8 of the cable 4 passes through the hole 43 of the plastron 37, engages between the lips 49 of the lyre 46 of the contact terminal 12 then, depending on the stripping length and the driving depth of the cable 4 in the cell 27, a portion of the stripped core 8 passes or not through the hole 50 and is housed in the passage 42 and in the compartment 41, as well as shown in Figure 5.

L'opérateur peut vérifier visuellement, en regardant la lyre 46, que l'âme 8 y est bien en place.The operator can visually check, looking at the lyre 46, that the soul 8 is in place.

Il suffit, ensuite, pour terminer le raccordement du câble 4, de rabattre le capot 3 pour lui faire prendre la position montrée sur les figures 1 et 5.Then, just to complete the connection of the cable 4, fold down the hood 3 to make it take the position shown in Figures 1 and 5.

A la fin du mouvement de rabattement du capot 3, les griffes 66 pénètrent dans la gaine extérieure 5 du câble 4 tandis que les crans 44 des pattes d'encliquetage 39 se mettent en place dans les ouvertures 58.At the end of the folding movement of the hood 3, the claws 66 penetrate the outer sheath 5 of the cable 4 while the notches 44 of the legs snap-fastener 39 fit into the openings 58.

Dans la position rabattue (figure 1 et 5), le capot 3 est verrouillé au socle 2 grâce aux pattes 39, la face droite du cran 44 de chacune des pattes 39 étant alors contre de la face 59 de la fenêtre 58 correspondante.In the folded position (FIGS. 1 and 5), the cover 3 is locked to the base 2 thanks to the legs 39, the right face of the notch 44 of each of the legs 39 being then against the face 59 of the corresponding window 58.

Le câble 4 est maintenu dans le dispositif 1 grâce aux griffes 66 et grâce aux pattes 67 qui sont alors disposées chacune dans l'un des espaces latéraux existant entre les arches 29 et 30, les arêtes 68 étant appliquées contre la gaine extérieure 5 et coinçant celle-ci contre la lame 31.The cable 4 is held in the device 1 thanks to the claws 66 and thanks at the legs 67 which are then each arranged in one of the lateral spaces existing between the arches 29 and 30, the edges 68 being applied against the sheath 5 and wedging it against the blade 31.

On observera que les moyens d'encliquetage que constituent les pattes 39 et les fenêtres 58 sont situés de part et d'autre des organes de retenue que constituent les griffes 66 et les patte 67, ces moyens d'encliquetage étant plus généralement situés de part et d'autre de la lame de contact 31.It will be observed that the snap-fastening means constituted by the tabs 39 and the windows 58 are located on either side of the retainers that constitute the claws 66 and the tab 67, these snap-fastening means being more generally located on either side of the contact blade 31.

Le verrouillage entre le socle 2 et le capot 3 s'effectue donc au plus près de ces organes de retenue, ce qui est favorable à la qualité du maintien qu'ils procurent. The locking between the base 2 and the cover 3 is thus carried out as closely as possible of these retainers, which is favorable to the quality of the maintenance they provide.

L'arche 29 de la cage 21 est disposée dans l'ouverture 57 de même contour du capot 3, la face externe de la cage 21 et celle du capot 3 étant à fleur l'une de l'autre, ainsi qu'on le voit sur la figure 1.The arch 29 of the cage 21 is disposed in the opening 57 likewise outline of the hood 3, the external face of the cage 21 and that of the hood 3 being flush from each other, as shown in Figure 1.

L'arche 30 de la cage 21 est quant à elle emboítée dans le creux de la nervure 65. La nervure 64 est placée contre la tranche du plastron 37 tandis que la nervure 63 s'emboíte contre le sommet de la cloison 22, du côté interne de cette dernière.The arch 30 of the cage 21 is nested in the hollow of the rib 65. The rib 64 is placed against the edge of the plastron 37 while the rib 63 engages against the top of the partition 22, on the inner side of this last.

La tranche de la paroi latérale du capot 3 est pour sa part disposée contre la face 20, juste autour de la rainure 23. Dans celle-ci est reçu une languette 52 que comporte le capot 3, le long du bord interne de la tranche de sa paroi latérale, en saillie par rapport à cette tranche.The edge of the side wall of the cover 3 is arranged for its part against the face 20, just around the groove 23. In it is received a tongue 52 that includes the cover 3, along the inner edge of the edge of its wall lateral projection projecting from this slice.

On observera que la paroi de fond du capot 3 forme avec les nervures 63 et 64 une sorte de calotte, laquelle forme avec la cloison 22 une coquille enveloppant la partie dénudée de l'âme centrale 8 et la lyre 46 de la borne de contact 12 de sorte qu'il existe une bonne continuité entre le blindage procuré par la tresse 6 du câble 4 et celui procuré par le dispositif 1. Cette continuité est favorable aux performances du dispositif 1, notamment en ce qui concerne la compatibilité électro-magnétique (CEM).It will be observed that the bottom wall of the cover 3 forms with the ribs 63 and 64 a kind of cap, which forms with the partition 22 a shell enveloping the bare part of the central core 8 and the lyre 46 of the terminal contact 12 so that there is good continuity between the shielding provided by the braid 6 of the cable 4 and that procured by the device 1. This continuity is favorable to the performance of the device 1, in particular as regards the electromagnetic compatibility (EMC).

Enfin, la rainure 61 est logée dans l'encoche 62, leur coopération lors du rabattement du capot 3 permettant un centrage de celui-ci par rapport au corps 2.Finally, the groove 61 is housed in the notch 62, their cooperation during the folding of the cover 3 allowing a centering thereof relative to the body 2.

Dans l'exemple illustré sur les figures 1 à 5, l'embout 9 est du type IEC femelle, le fût 17 étant prévu pour recevoir intérieurement le fût d'une fiche correspondante et la queue 45 étant prévue pour recevoir intérieurement la broche de cette fiche.In the example illustrated in FIGS. 1 to 5, the tip 9 is of the IEC type female, the barrel 17 being adapted to receive internally the barrel of a plug corresponding and the tail 45 being provided to internally receive the spindle of this form.

La variante 1' du dispositif 1 illustrée sur la figure 6 est identique, si ce n'est que l'embout 9 est remplacé par un embout 9' de type F.The variant 1 'of the device 1 illustrated in FIG. 6 is identical, if is only the tip 9 is replaced by a tip 9 'type F.

Plus précisément, le corps 10 est remplacé par un corps 10' où le fût 17 est remplacé par un fût 17' présentant un filetage externe, l'insert 11 est remplacé par un insert 11' où le pied 35 est remplacé par un pied 35' s'étendant sur toute la longueur du fût 17' et la borne 12 est remplacée par une borne 12' où la queue 45 est remplacée par une queue 45' propre à recevoir intérieurement un tronçon d'extrémité dénudé de l'âme centrale d'un câble coaxial. More specifically, the body 10 is replaced by a body 10 'where the barrel 17 is replaced by a drum 17 'having an external thread, the insert 11 is replaced by an insert 11 'where the foot 35 is replaced by a foot 35' extending over the entire length of the drum 17 'and the terminal 12 is replaced by a terminal 12' where the tail 45 is replaced by a tail 45 'clean to receive internally a section denuded end of the central core of a coaxial cable.

Dans une variante non représentée, l'embout 9 est remplacé par un embout IEC mâle ou encore par un embout de connexion d'un autre type.In a variant not shown, the tip 9 is replaced by a IEC male terminal or by a connection tip of another type.

Dans d'autres variantes non représentées, le nombre de griffes telles que 66 est différent, c'est-à-dire qu'il y a une seule griffe ou davantage que deux griffes ; de même pour les pattes 67 ; il y a un seul type d'organe de retenue tel que les griffes 66 et les pattes 67 ou alors davantage que deux types ; et/ou les organes de retenue prévus pour agripper à l'opposé de la lame de contact telle que 31 la gaine isolante extérieure 5, sont conformés différemment.In other variants not shown, the number of claws such that 66 is different, that is, there is only one claw or more than two claws; similarly for the legs 67; there is only one type of restraint that the claws 66 and the legs 67 or more than two types; and / or retaining members provided for gripping away from the contact blade as 31 the outer insulating sheath 5, are shaped differently.

Dans encore d'autres variantes non représentées du dispositif 1, ce n'est pas l'intégration à une prise murale qui est prévue, mais une autre forme de dispositif de connexion, par exemple une fiche autonome à installer à une extrémité d'un câble coaxial. Dans ce dernier cas, ou d'ailleurs dans d'autres variantes, l'embout tel que 9 ou 9' est aligné avec l'alvéole telle que 27 (et non d'équerre avec celle-ci) ; le capot tel que 3 est articulé autour d'un axe de pivotement situé ailleurs qu'à l'opposé de la bouche d'entrée dans l'alvéole telle que 27, par exemple du côté de cette bouche d'entrée ; le capot tel que 3 est remplacé par un capot non articulé sur le socle tel que 2, par exemple un capot séparé se fixant sur le socle tel que 2 uniquement par encliquetage ; et/ou le corps tel que 10 et le couvercle tel que 3 sont en matière conductrice autre que du métal, par exemple en matière plastique recouverte d'une pellicule conductrice.In still other variants not shown of the device 1, this is not integration to a wall outlet that is intended but another form of connection device, for example a stand-alone plug to be installed at a end of a coaxial cable. In the latter case, or elsewhere in other variants, the tip such as 9 or 9 'is aligned with the cell such as 27 (and not square with it); the hood such as 3 is articulated around an axis of pivoting located elsewhere than the opposite of the inlet mouth in the cell such than 27, for example on the side of this mouth of entry; the hood such as 3 is replaced by a non-articulated hood on the base such as 2, for example a hood separate fixing on the base such as 2 only snap; and / or the body such as 10 and the cover such as 3 are made of conductive material other than metal, for example plastic covered with a conductive film.

De nombreuses autres variantes sont possibles en fonction des circonstances, et on rappelle à cet égard que l'invention ne se limite pas aux exemples décrits et représentés.Many other variants are possible depending on the circumstances, and it is recalled in this respect that the invention is not limited to examples described and represented.
