La présente invention concerne un connecteur pour câbles électriques isolés, et plus particulièrement un connecteur de type comportant un manchon conducteur ayant deux logements opposés pour 05 les extrémités dénudées de deux câbles à connecter, une jupe The present invention relates to a connector for insulated electrical cables, and more particularly to a connector of the type comprising a conductive sleeve having two opposite housings for the stripped ends of two cables to be connected, a skirt
isolante entourant le manchon et des joints d'étanchéité interposés entre la jupe et les extrémités des gaines d'isolation des câbles, la liaison mécanique entre le connecteur et les extrémités dénudées des câbles devant être réalisée par sertissage 10 du connecteur sur les extrémités des câbles. insulation surrounding the sleeve and seals interposed between the skirt and the ends of the cable insulation sheaths, the mechanical connection between the connector and the stripped ends of the cables having to be carried out by crimping 10 of the connector on the ends of the cables .
Dans des connecteurs connus de ce type, les joints d'étanchéité sont chacun placés entre la jupe et la surface périphérique de la gaine d'isolation d'un câble, à l'extrémité de celle-ci Lors du sertissage, le manchon s'allonge et comprime le 15 joint entre la gaine du câble et la jupe La figure 1 illustre un tel connecteur connu; la partie droite montre le connecteur avant sertissage, avec le manchon 1, la jupe 2 et le joint d'étanchéité 3; la partie gauche montre le connecteur après sertissage, le manchon 1 étant serti sur l'extrémité dénudée du câble tandis que 20 le joint d'étanchéité est comprimé entre la gaine d'isolation du In known connectors of this type, the seals are each placed between the skirt and the peripheral surface of the insulation sheath of a cable, at the end of the latter. During crimping, the sleeve lengthens and compresses the joint between the cable sheath and the skirt FIG. 1 illustrates such a known connector; the right part shows the connector before crimping, with the sleeve 1, the skirt 2 and the seal 3; the left part shows the connector after crimping, the sleeve 1 being crimped on the stripped end of the cable while the seal is compressed between the insulation sheath of the
câble et la jupe par suite de l'allongement du manchon. cable and skirt as a result of the elongation of the sleeve.
L'étanchéité diélectrique réalisée par le joint 3 après sertissage n'est pas toujours satisfaisante En effet, pour un même joint, cette étanchéité dépend de la forme de la gaine du 25 câble, forme qui varie selon les fabricants De plus, dans le cas de lignes polyphasées, le repérage des phases est parfois réalisé par des marques en relief sur les gaines des câbles, ce qui The dielectric tightness produced by the joint 3 after crimping is not always satisfactory. In fact, for the same joint, this tightness depends on the shape of the cable sheath, a shape which varies according to the manufacturer. In addition, in the case polyphase lines, the phases are sometimes identified by raised marks on the cable sheaths, which
empêche l'obtention d'une bonne étanchéité diélectrique. prevents good dielectric tightness.
La présente invention a pour but de remédier à cet 30 inconvénient en proposant un connecteur grâce auquel une bonne The object of the present invention is to remedy this drawback by proposing a connector by which a good
étanchéité diélectrique est obtenue indépendamment de possibles variations de forme de la gaine extérieure des câbles à raccorder. dielectric tightness is obtained independently of possible variations in shape of the outer sheath of the cables to be connected.
Ce but est atteint au moyen d'un connecteur du type This object is achieved by means of a connector of the type
défini en tête de la présente description et dans lequel, 35 conformément à l'invention, les joints d'étanchéité sont destinés defined at the beginning of this description and in which, in accordance with the invention, the seals are intended
à être placés sur les extrémités dénudées des câbles, chacun entre une butée interne solidaire de la jupe et la face terminale de la gaine d'isolation du câble associé, l'étanchéité diélectrique étant réalisée par compression de chaque joint d'étanchéité entre 05 ladite butée interne et ladite face terminale par suite de to be placed on the stripped ends of the cables, each between an internal stop integral with the skirt and the end face of the insulation sheath of the associated cable, the dielectric sealing being produced by compression of each seal between 05 said internal stop and said end face as a result of
l'allongement de la jupe lors du sertissage. lengthening the skirt during crimping.
De la sorte, l'étanchéité diélectrique obtenue est rendue indépendante de possibles variations ou irrégularités de In this way, the dielectric seal obtained is made independent of possible variations or irregularities in
forme de la gaine d'isolation des câbles. shape of the cable insulation sheath.
Pour réaliser une compression efficace des joints d'étanchéité lors du sertissage, la jupe est en un matériau synthétique dont le coefficient d'allongement est supérieur à To achieve effective compression of the seals during crimping, the skirt is made of a synthetic material whose elongation coefficient is greater than
celui du matériau formant le manchon. that of the material forming the sleeve.
L'invention sera mieux comprise à la lecture de la 15 description faite ci-après, à titre indicatif mais non limitatif, The invention will be better understood on reading the description given below, by way of indication but not limitation,

également en un matériau synthétique isolant. also in an insulating synthetic material.
Le manchon cylindrique 11 comprend deux logements opposés 12, 13 s'ouvrant sur ses faces d'extrémité et destinés à 30 recevoir les extrémités dénudées 23, 24 des câbles à raccorder 25, The cylindrical sleeve 11 comprises two opposite housings 12, 13 opening on its end faces and intended to receive the stripped ends 23, 24 of the cables to be connected 25,
26 (montrés en tirets sur la figure 2). 26 (shown in dashes in Figure 2).
La jupe 15 est en deux parties 16, 17 mises en place sur le manchon 11 à partir des deux extrémités de celui-ci et réunies dans la partie centrale du connecteur par surmoulage d'une pièce 35 de liaison 20 en un matériau semblable à celui des parties 16 et 17 La pièce 20 présente une partie centrale moulée sur une collerette 14 du manchon 11 et deux parties annulaires latérales pénétrant dans des rainures formées dans les parties 16, 17 au The skirt 15 is in two parts 16, 17 placed on the sleeve 11 from the two ends of the latter and joined in the central part of the connector by overmolding a connecting piece 35 of a material similar to that of parts 16 and 17 The part 20 has a central part molded on a collar 14 of the sleeve 11 and two lateral annular parts penetrating into grooves formed in parts 16, 17 at
voisinage de leurs extrémités adjacentes. near their adjacent ends.
A ses extrémités, la jupe 15 a des parties terminales 16 a, 17 a de plus grande épaisseur dont le -diamètre interne correspond sensiblement au diamètre extérieur des gaines d'isolation 27, 28 des câbles 25, 26 Des collerettes internes 18, 19 solidaires de la jupe 15 sont formées sensiblement au niveau 10 des raccordements des parties terminales 16 a, 17 a avec le reste de la jupe 15; elles limitent l'engagement des parties de jupe 16, 17 sur le manchon 11 en venant au contact des extrémités du manchon et ont un diamètre interne supérieur à celui de la partie dénudée At its ends, the skirt 15 has end portions 16 a, 17 has greater thickness, the internal diameter of which corresponds substantially to the external diameter of the insulation sheaths 27, 28 of the cables 25, 26 of the internal flanges 18, 19 integral of the skirt 15 are formed substantially at level 10 of the connections of the end portions 16 a, 17 a with the rest of the skirt 15; they limit the engagement of the skirt parts 16, 17 on the sleeve 11 by coming into contact with the ends of the sleeve and have an internal diameter greater than that of the stripped part
des câbles.Cables.
Les joints d'étanchéité 21, 22 sont logés dans les parties terminales 16 a, 17 a de la jupe 15 Ils sont par exemple en caoutchouc synthétique et ont une section transversale sensiblement égale à celle des gaines d'isolation 27, 28 des câbles 25, 26 On pourra toutefois conférer aux joints 21, 22 un 20 diamètre extérieur légèrement supérieur au diamètre intérieur des parties terminales 16 a, 17 a de sorte que les joints 21, 22 The seals 21, 22 are housed in the end portions 16 a, 17 a of the skirt 15 They are for example made of synthetic rubber and have a cross section substantially equal to that of the insulation sheaths 27, 28 of the cables 25 , 26 However, it is possible to give the seals 21, 22 an outside diameter slightly greater than the inside diameter of the end portions 16 a, 17 a so that the seals 21, 22
puissent être immobilisés à demeure aux extrémités de la jupe 15. can be permanently immobilized at the ends of the skirt 15.
Le raccordement des câbles 25, 26 est réalisé comme suit. Les extrémités dénudées 23, 24 des câbles 25, 26 sont introduites dans les logements 12, 13 à travers les joints 21, 22 jusqu'à ce que les faces terminales 27 a, 28 a des gaines d'isolation 27 a, 28 a viennent au contact des joints 21, 22, The cables 25, 26 are connected as follows. The stripped ends 23, 24 of the cables 25, 26 are introduced into the housings 12, 13 through the seals 21, 22 until the end faces 27 a, 28 have insulating sheaths 27 a, 28 a in contact with the seals 21, 22,
appliquant ceux-ci contre les collerettes 18, 19. applying these against the flanges 18, 19.
Ensuite, le connecteur 10 est serti sur chaque extrémité Then, the connector 10 is crimped on each end
de câble Au cours du sertissage, le manchon 11 est serré successivement sur l'une et l'autre extrémité dénudée, assurant la liaison mécanique et électrique entre les câbles 25, 26. of cable During crimping, the sleeve 11 is successively tightened on one and the other stripped end, ensuring the mechanical and electrical connection between the cables 25, 26.
Simultanément, les parties de jupes 16, 17 s'allongent, comprimant 35 les joints 21, 22. Simultaneously, the parts of skirts 16, 17 are elongated, compressing the joints 21, 22.
Après sertissage (figure 3), les joints 21, 22 se trouvent écrasés entre les collerettes 18, 19 et les faces terminales 27 a, 28 a des gaines d'isolation 27, 28 Les joints assurent ainsi une parfaite étanchéité diélectrique indépendamment 05 de variations de forme ou de dimension des gaines 27, 28 pouvant donner naissance à des jeux entre les surfaces périphériques de After crimping (Figure 3), the seals 21, 22 are crushed between the flanges 18, 19 and the end faces 27 a, 28 has insulating sheaths 27, 28 The seals thus ensure perfect dielectric tightness regardless of variations 05 of shape or size of the sheaths 27, 28 which can give rise to clearances between the peripheral surfaces of
celles-ci et les parties terminales de la jupe 15. these and the end parts of the skirt 15.
Afin d'assurer une compression efficace des joints 21, 22 on choisit pour les parties de jupe 16, 17 un matériau ayant un 10 coefficient d'allongement supérieur à celui du matériau constitutif du manchon 11 A titre d'exemple, on peut choisir pour les parties de jupe 16, 17 une matière plastique injectable telle qu'une polyamide, le manchon 11 étant en un alliage d'aluminium tel que celui connu sous la dénomination AS Cette différence de 15 coefficient d'allongement se traduit, après sertissage, par des jeux 31, 32 entre les extrémités du manchon 11 et les collerettes In order to ensure effective compression of the seals 21, 22, a material having a coefficient of elongation greater than that of the material constituting the sleeve 11 is chosen for the skirt parts 16, 17. As an example, it is possible to choose for the skirt parts 16, 17 an injectable plastic material such as a polyamide, the sleeve 11 being of an aluminum alloy such as that known under the name AS This difference in elongation coefficient results, after crimping, by clearances 31, 32 between the ends of the sleeve 11 and the flanges
18, 19.18, 19.
