Description

LIAISON ELECTRIQUE DE CAPTEUR SENSOR ELECTRICAL CONNECTION
La présente invention vise la liaison électrique de capteurs tels que ceux utilisés notamment pour l'aide au parcage de véhicules. Ces capteurs sont disposés sur les pare-chocs de véhicules et sont soumis aux intempéries. On doit donc réaliser une liaison étanche entre les conducteurs d'alimentation et ceux utilisés pour véhiculer l'information, et les capteurs.The present invention relates to the electrical connection of sensors such as those used in particular for vehicle parking assistance. These sensors are placed on the bumpers of vehicles and are subjected to bad weather. It is therefore necessary to achieve a sealed connection between the supply conductors and those used to convey the information, and the sensors.
L'un des buts de l'invention est de réaliser une liaison électrique étanche entre les capteurs et les conducteurs de manière à pouvoir réaliser, en atelier directement, l'ensemble complet, prêt à poser.One of the aims of the invention is to provide a sealed electrical connection between the sensors and the conductors so as to be able to carry out, in the workshop directly, the complete assembly, ready to install.
La liaison électrique entre les capteurs et les conducteurs, selon l'invention, est du type dans lequel les capteurs présentent une jupe dans laquelle s'étendent des languettes de contacts électriques et est caractérisée en ce qu'elle comprend une prise dans laquelle sont logés des organes de contact électrique femelles destinés à coopérer avec les languettes et reliés aux conducteurs, ladite prise étant insérée dans un organe de guidage destiné à coopérer avec la paroi interne de la jupe, en ménageant vers l'extrémité libre de celle-ci un espace libre rempli d'une épaisseur de matière plastique.The electrical connection between the sensors and the conductors, according to the invention, is of the type in which the sensors have a skirt in which tongues of electrical contacts extend and is characterized in that it comprises a socket in which are housed female electrical contact members intended to cooperate with the tongues and connected to the conductors, said plug being inserted into a guiding member intended to cooperate with the inner wall of the skirt, leaving a free space towards the free end thereof; free filled with a thickness of plastic material.
Suivant une caractéristique particulière, l'organe de guidage comporte des ailettes destinées à porter contre la face interne de la jupe au voisinage du fond de celle-ci. Ainsi, on évite le fluage de la matière plastique jusqu'aux contacts électriques. Afin d'assurer une bonne tenue des conducteurs, l'épaisseur de matière plastique déborde sur les conducteurs.According to a particular characteristic, the guide member comprises fins intended to bear against the inner face of the skirt in the vicinity of the bottom thereof. Thus, it avoids the creep of the plastic material to the electrical contacts. In order to ensure a good behavior of the conductors, the thickness of plastic material overflows on the conductors.
Enfin, de préférence, les conducteurs sont du type disposés en nappes méplates et noyés dans un isolant.Finally, preferably, the conductors are of the type arranged in flat plies and embedded in an insulator.
L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et représentés au dessins annexés.The invention will now be described in more detail with reference to particular embodiments given by way of example only and represented in the accompanying drawings.
Figure 1 montre en plan, partiellement en coupe, un premier mode de réalisation d'une liaison avec un capteur.Figure 1 shows in plan, partially in section, a first embodiment of a connection with a sensor.
Figure 2 est une vue en élévation éclatée, certaines parties étant représentées en coupe.Figure 2 is an exploded elevational view, some parts being shown in section.
Figure 3 montre en coupe une partie des éléments montés. Figure 4 montre en coupe l'ensemble terminé.Figure 3 shows in section a part of the mounted elements. Figure 4 shows in section the complete set.
Figure 5 montre en coupe éclatée une variante de réalisation de l'invention.Figure 5 shows in exploded section an alternative embodiment of the invention.
Figure 6 montre en coupe les éléments montés. Figure 7 montre en coupe l'ensemble terminé.Figure 6 shows in section the mounted elements. Figure 7 shows in section the complete set.
Dans le premier mode de réalisation correspondant aux figures 1 à 4, la référence 1 désigne un capteur qui est prolongé par une jupe 2 à l'intérieur de laquelle s'étendent des languettes 3.In the first embodiment corresponding to FIGS. 1 to 4, the reference 1 denotes a sensor which is extended by a skirt 2 inside which tongues 3 extend.
La référence 5 désigne une prise qui comporte, intérieurement dans des canaux, des organes de connexion électrique femelles 6 reliés chacun à un conducteur 8.Reference 5 designates a socket which comprises, internally in channels, female electrical connection members 6 each connected to a conductor 8.
Le conducteur est constitué par l'une des pistes d'un ensemble méplat 8 comportant, noyé dans un isolant, une série de pistes conductrices.The conductor is constituted by one of the tracks of a flattened assembly 8 comprising, embedded in an insulator, a series of conductive tracks.
Il est prévu un organe de guidage 10 destiné à être monté sur la prise 5 afin que, lors de la mise en place de celle-ci, les organes femelles 6 soient parfaitement présentés en regard des languettes 3 pour assurer une bonne liaison électrique.There is provided a guide member 10 to be mounted on the socket 5 so that, during the establishment of the latter, the female members 6 are perfectly presented opposite the tabs 3 to ensure a good electrical connection.
La prise 5 présente un ergot 12 qui est destiné, moyennant une déformation élastique, à s'engager dans une rainure 13 de l'organe de guidage 10, cette rainure étant terminée par un épaulement 14 de manière que la prise puisse être engagée dans l'organe de guidage 10, mais ne puisse être dégagée.The plug 5 has a lug 12 which is intended, by elastic deformation, to engage in a groove 13 of the guide member 10, this groove being terminated by a shoulder 14 so that the engagement can be engaged in the guide member 10, but can not be disengaged.
Lorsque la prise 5 est mise en place, on procède à un surmoulage en injectant une épaisseur de matière plastique 16 qui remplit la jupe dans un espace libre 17 ménagé derrière la prise 5 et dans laquelle une partie des conducteurs méplats est noyée.When the plug 5 is put in place, an overmoulding is performed by injecting a thickness of plastic material 16 which fills the skirt in a free space 17 formed behind the plug 5 and in which a part of the flat conductors is embedded.
Une telle disposition assure l'étanchéité et évite un arrachement de la prise et des conducteurs.Such an arrangement ensures tightness and prevents tearing of the plug and conductors.
Les figures 5 à 7 montrent une variante de réalisation dans laquelle le capteur 20 présente une jupe 21 dans laquelle s'étendent des languettes de contact 22.FIGS. 5 to 7 show an alternative embodiment in which the sensor 20 has a skirt 21 in which contact tabs 22 extend.
Il est prévu une prise 24 pourvue de canaux dans lesquels sont logés et verrouillés des organes de contact électrique femelles 29 destinés à coopérer avec les languettes 22 et sertis, aux extrémités des pistes, d'une nappe méplate 25. La prise est logée dans un organe de guidage 26 destiné à s'insérer dans la jupe 21 et comportant, à une extrémité libre 26a, des ailettes 28.There is provided a socket 24 provided with channels in which are housed and locked female electrical contact members 29 intended to cooperate with the tongues 22 and crimped at the ends of the tracks with a flat sheet 25. The plug is housed in a guide member 26 intended to be inserted into the skirt 21 and comprising, at a free end 26a, fins 28.
Lorsque la prise avec l'organe de guidage 26 est insérée dans la jupe 21 , les ailettes 28 portent par leur bord libre contre la surface interne de la jupe 21 et ainsi assurent l'étanchéité du fond de ladite jupe.When the engagement with the guide member 26 is inserted into the skirt 21, the fins 28 carry their free edge against the inner surface of the skirt 21 and thus seal the bottom of said skirt.
Lorsque la prise est mise en place avec son organe de guidage, il est ménagé à l'arrière de la prise un espace libre 30 dans lequel on surmoule une épaisseur de matière plastique 31 qui, compte tenu des ailettes 28, ne peut fluer vers le fond de la jupe de sorte que la matière plastique ne peut venir jusqu'aux organes de contact électrique.When the plug is put in place with its guide member, there is arranged at the rear of the socket a free space 30 in which a thickness of plastic material 31 is overmolded which, taking into account the fins 28, can not flow towards the bottom of the skirt so that the plastic material can only come up to the electrical contact members.
Lors du surmoulage, on exerce une pression sur l'extrémité de l'organe de guidage 26 opposée à l'extrémité 26a afin que la nappe de conducteurs 25 soit parfaitement emprisonnée dans l'extrémité correspondante de l'organe de guidage 26, le surmoulage s'étendant au-delà de ladite extrémité afin de parfaitement tenir la nappe de conducteurs.During overmolding, pressure is exerted on the end of the guide member 26 opposite the end 26a so that the layer of conductors 25 is perfectly trapped in the corresponding end of the guide member 26, overmolding extending beyond said end to perfectly hold the layer of conductors.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention. Of course, the invention is not limited to the embodiments that have just been described and shown. It will be possible to make many changes in detail without departing from the scope of the invention.
