Description

La présente invention est destinee remédier a des problèmes, particulièrement dans la construction automobile, dans le montage des antennes radio. The present invention is intended to remedy problems, particularly in automobile construction, in the mounting of radio antennas.

Dans les réalisations connues, le raccordement du blindage du fable coaxial h la masse du véhicule est rarement satisfaisant, il est habituellement assuré par une rondelle munie d'une denture extérieure en appui sur la tôle de carrosserie; du fait des protections anti-corrosion dont sont maintenant revetues les tales, la conductibilité électrique est faible ou nulle, d'ou une réception radio défectueuse. In known embodiments, the connection of the shielding of the coaxial fable to the mass of the vehicle is rarely satisfactory, it is usually provided by a washer provided with external toothing bearing on the body sheet; because of the anti-corrosion protections with which the sheets are now coated, the electrical conductivity is low or zero, hence a faulty radio reception.

Le connecteur de raccordement a l'antenne n'est pas protégé des parasites et il est nécessaire d'y ajouter une pièce de protection supplémentaire. The antenna connection connector is not protected from interference and it is necessary to add an additional protective part.

Les antennes actuellement connues sont telles que leur installation est peu aisée, il est en effet indispensable de travailler simultanément des deux cotés de la tôle support; dans la construction automobile cela implique dans certains cas de personnes; de plus quand l'antenne n'est pas installée d'origine sur le véhicule, ou en cas de remplacement, il faut dégarni@ l'intérieur pour avoir accès à la tôle, ce qui est délicat et conteux. The antennas currently known are such that their installation is not very easy, it is indeed essential to work simultaneously on both sides of the support sheet; in automobile construction this in some cases involves people; more when the antenna is not originally installed on the vehicle, or in case of replacement, it must be stripped @ inside to have access to the sheet, which is delicate and costly.

L'invention qui a pour but de remédier a ces défauts est représentée par les dessins annexes - La figure représente une coupe de connecteur. The invention which aims to remedy these defects is shown in the accompanying drawings - The figure shows a connector section.

- La figure 2 représente une vue de connecteur. - Figure 2 shows a connector view.

- La fiqure s représente une coupe de l'assemblage du connecteur et de l'embase d'antenne montée sur la tôle support, avant le serrage de la wi5 de fixation. - Figure fiqure a section of the connector assembly and the antenna base mounted on the support plate, before tightening the wi5 fixing.

Selon l'invention, le connecteur est constitué d'une pièce plastique moulée 1, sur une des faces de cette pièce 1 est montée une pièce circulaire métallique 2 dont un prolongement en forme de patte vient assurer un contact électrique avec le cable coaxial 7". Sur l'autre face de la pièce I est montée et encastrée dans un évidement une autre pièce métallique 4 présentant un logement hexagonal dans lequel viendra se loger un écrou 5 de contour hexagones la pièce 4 est reliée électriquement, pa soudure , a l'ame du coaxial; une pièce plastique 6 viendra coiffer l'écrou 5 de façon a le maintenir dans son logement sans jeu. According to the invention, the connector consists of a molded plastic part 1, on one of the faces of this part 1 is mounted a circular metal part 2 of which a lug-shaped extension ensures electrical contact with the coaxial cable 7 " On the other face of the part I is mounted and embedded in a recess another metal part 4 having a hexagonal housing in which will be accommodated a nut 5 of hexagonal outline the part 4 is electrically connected, by welding, to the core of the coaxial; a plastic part 6 will cap the nut 5 so as to keep it in its housing without play.

L'ensemble de l'empilage de la pièce métallique 2, de l'isolant 1 de la pièce métallique 4 et de la pièce plastique 6 est serré et maintenu en place par un capot métallique 7 serti sur la pièce 2 par trois crantages 7.1-7.2-7.3 ; une partie de ce capot 7 est conforme de façon a permettre la pénétration du coaxial 7.4, cette partie sera sertie sur le cable et la patte de la pièce 2 simultanément avec les trois autres sertissages 7.1-7.2-7.3. Le capot 7 assure donc une immobilisation axiale et radiale de l'écrou 5 et solidarise le cable 3 avec l'ensemble connecteur, elle assure de plus un blindage total de ce connecteur. The entire stack of the metal part 2, of the insulator 1 of the metal part 4 and of the plastic part 6 is tightened and held in place by a metal cover 7 set on the part 2 by three notches 7.1- 7.2-7.3; part of this cover 7 conforms so as to allow penetration of the coaxial 7.4, this part will be crimped onto the cable and the tab of the part 2 simultaneously with the other three crimps 7.1-7.2-7.3. The cover 7 therefore ensures axial and radial immobilization of the nut 5 and secures the cable 3 with the connector assembly, it also provides total shielding of this connector.

L'ensemble des pièces 2-1-4-6 présente un logement cylindrique axial prévu pour le passage de la vis et de l'isolant de l'embase d'antenne.  All of the parts 2-1-4-6 have an axial cylindrical housing provided for the passage of the screw and of the insulation of the antenna base.

L'isolateur 1 est éqipé de trois pattes a griffe semisouples 1.1-1.2-1.3 destinées a se clipser sur la tôle support 8 et a maintenir le connecteur en place comme représenté sur la figure 3. The insulator 1 is equipped with three semi-flexible claw legs 1.1-1.2-1.3 intended to be clipped onto the support sheet 8 and to hold the connector in place as shown in FIG. 3.

La pièce 2, en plus de la denture circulaire extérieure est équipée sur le pourtour de son ajour intérieur de trois dents 2.1-2.2-2.3 relevées à la perpendiculaire. Le connecteur étant clipsé sur la tôle support 8, les dites dents sont conformées de façon a ce que le champ du perçage de la tôle vienne s'appuyer sur le haut de la pente de l'arête extérieure de chacune d'elles comme représenté sur la figure 3
L'embase de l'antenne est constituée d'une piece métallique 9 devant supporter le brin d'antenne (nan represente), d'une pièce isolante t et d'une vis il pouvant coulisser dans ces pièces.The part 2, in addition to the external circular toothing, is equipped on the periphery of its internal opening with three teeth 2.1-2.2-2.3 raised perpendicularly. The connector being clipped onto the support sheet 8, the said teeth are shaped so that the drilling field of the sheet comes to rest on the top of the slope of the outer edge of each of them as shown in figure 3
The antenna base consists of a metal part 9 which must support the antenna strand (nan represented), an insulating part t and a screw which can slide in these parts.

Dans la pièce 10, un évidement 10.1 est aménage pou permettre le logement de la partie dépassant au dessus de la tôle des clips de la pièce 1 et des dents de la pièce 2.  In the part 10, a recess 10.1 is arranged to allow the housing of the part projecting above the sheet metal of the clips of the part 1 and the teeth of the part 2.

Ladite pièce 10 est de plus équipée d'un canon tubulaire 10.2 isolant la vis 11, ce canon est pourvu sur son pourtour extérieur de nervures 10.3 ; ces nervures sont prévues pour 'engager dans les nervures correspondantes i. 4 de l'isolateur i du connecteur.Said part 10 is further equipped with a tubular barrel 10.2 insulating the screw 11, this barrel is provided on its outer periphery with ribs 10.3; these ribs are designed to 'engage in the corresponding ribs i. 4 of the isolator i of the connector.

Àu montage, le connecteur ayant été mis en place et maintenu par les trois clips 1.1-1.2-13. sur la tôle support: de l'extérieur on peut introduire le canon 10.2 de l'embase entre les clips, son introduction les bloquant en place et empèchant tout arrachement de connecteur ; les nervures 10.3 du canon 10.2 engagées dans celles 1.4 de la pièce 1 solidarisent en rotation le connecteur à l'embase. At assembly, the connector having been put in place and maintained by the three clips 1.1-1.2-13. on the support plate: from the outside, it is possible to introduce the barrel 10.2 of the base between the clips, its introduction locking them in place and preventing any connector tearing; the ribs 10.3 of the barrel 10.2 engaged in those 1.4 of the part 1 secure in rotation the connector to the base.

La compression de l'ensemble : embase-ttle supportconnecteur résultant du vissage de la vis 11 dans l'écrou 5 a pour effet de serrer le perçage de la tôle 8 sur les arêtes extérieures inclinées 2.1-2.2-2.3 de la pièce 2 provoquant la déchirure du champ de ce perçage et de sa protection isolante. Cette agression sera stabilisée quand le serrage amènera la tôle 8 en appui sur la denture extérieure 2.4 de la pièce 2 (position 8.1 sur la figure 4
La réalisation décrite ci-dessus n'est pas limitative, entre autre l'ensemble vis 11 et écrou 5 pourraient avoir une disposition inverse : la vis étant incorporée au connecteur et l'écrou coopérant avec l'embase ; d 'autre part chaque élément de l'invention pourra etre réalisé séparément, en particulier l'aménagement de la pièce de contact de masse 2 avec sa denture intérieure, celle-ci sera alors solidarisée AU connecteur par un moyen quelconque. Compression of the assembly: base-ttle supportconnector resulting from the screwing of the screw 11 in the nut 5 has the effect of tightening the drilling of the sheet 8 on the inclined outer edges 2.1-2.2-2.3 of the part 2 causing the tearing of the field of this hole and its insulating protection. This aggression will be stabilized when the tightening brings the sheet 8 to bear on the external toothing 2.4 of part 2 (position 8.1 in FIG. 4
The embodiment described above is not limiting, among other things the screw 11 and nut 5 assembly could have a reverse arrangement: the screw being incorporated in the connector and the nut cooperating with the base; on the other hand each element of the invention may be produced separately, in particular the arrangement of the mass contact part 2 with its internal toothing, the latter will then be secured to the connector by any means.
