Description

L'invention concerne un connecteur pour circuit résistif solidai­re d'un support souple ainsi que les circuits résistifs souples mu­nis d'un tel connecteur.The invention relates to a connector for a resistive circuit secured to a flexible support as well as flexible resistive circuits provided with such a connector.

Les circuits résistifs souples sont utilisés pour le chauffage et/ou le désembuage de miroirs tels que des rétroviseurs exté­rieurs de véhicules automobiles ou des miroirs de salles de bains. En effet, ces circuits peuvent être facilement collés sur la face dépolie de la glace réfléchissante, par exemple au moyen d'un film autocollant.Flexible resistive circuits are used for heating and / or demisting mirrors such as exterior mirrors of motor vehicles or bathroom mirrors. Indeed, these circuits can be easily stuck on the frosted face of the reflecting glass, for example by means of a self-adhesive film.

Ces circuits nécessitent une connexion parfaitement étanche du fait de l'humidité dans laquelle ils sont appelés à fonctionner, cette humidité risquant en particulier d'oxyder les bornes de con­tact.These circuits require a perfectly sealed connection due to the humidity in which they are called upon to operate, this humidity running the risk of oxidizing the contact terminals in particular.

On a proposé (FR-A-89 06246) de fixer deux contacts mâles aux ex­trémités du circuit, de les replier sous forme de broches, et d'en­fermer les broches ainsi constituées dans un boîtier muni d'un bord en saillie ên appui sur la surface-du support du circuit. Cet­ te solution n'offre pas toutes les garanties d'étanchéité requi­ses et, en outre, l'encombrement dû au boîtier constitue une gêne dans certaines applications.It has been proposed (FR-A-89 06246) to fix two male contacts at the ends of the circuit, to fold them in the form of pins, and to enclose the pins thus formed in a box provided with a projecting edge in contact with the surface of the circuit support. This The solution does not offer all the required watertight guarantees and, moreover, the bulk due to the housing is a nuisance in certain applications.

La présente invention vise à fournir un nouveau connecteur ne pré­sentant pas les inconvénients des connecteurs connus.The present invention aims to provide a new connector which does not have the drawbacks of known connectors.

A cet effet, le connecteur selon l'invention est caractérisé en ce qu'il comprend deux fils de connexion fixés chacun à une extrémi­té respectivement à une extrémité du circuit résistif, et une pla­que isolante collée sur le support du circuit et recouvrant les ex­trémités du circuit résistif ainsi qu'une portion des fils de con­nexion, ladite plaque comportant un canal en forme de Y pour le passage des fils et deux bossages aux extrémités des branches du­dit canal pour le logement des moyens de fixation des fils sur le circuit.To this end, the connector according to the invention is characterized in that it comprises two connection wires each fixed at one end respectively to one end of the resistive circuit, and an insulating plate bonded to the support of the circuit and covering the ends of the resistive circuit as well as a portion of the connection wires, said plate comprising a Y-shaped channel for the passage of the wires and two bosses at the ends of the branches of said channel for housing the means for fixing the wires on the circuit.

On obtient ainsi un connecteur extrêmement plat et présentant une étanchéité élevée du fait de l'obturation du canal par les deux fils adjacents dans le pied de ce canal.An extremely flat connector is thus obtained which has a high level of tightness due to the obturation of the channel by the two adjacent wires in the base of this channel.

Avantageusement, l'extrémité libre de chaque fil est munie d'une fiche de connexion.Advantageously, the free end of each wire is provided with a connection plug.

De préférence, les fils de connexion sont munis d'une rondelle sou­dée, collée ou rivetée à l'extrémité correspondante du circuit ré­sistif.Preferably, the connection wires are provided with a welded washer, glued or riveted to the corresponding end of the resistive circuit.

L'invention concerne également les circuits résistifs souples mu­nis d'un tel connecteur. De préférence, le circuit résistif est constitué par un dépôt d'une encre résistive sur un support sou­ple en polyester ou en mylar.The invention also relates to flexible resistive circuits provided with such a connector. Preferably, the resistive circuit is formed by depositing a resistive ink on a flexible polyester or mylar support.

L'invention sera bien comprise à la lecture de la description sui­vante faite en se référant au dessin annexé dans lequel:

  • La figure 1 est une vue schématique de dessus d'un cir­ cuit selon un exemple de réalisation de l'invention, et la figure 2 est une vue schématique en coupe selon la li­gne II-II de la figure 1.

Le circuit 2 comporte deux bornes d'extré­mité 3.The flexible resistive circuit consists of a flexible support 1 made of polyester or mylar on which is deposited a circuit 2 formed by a resistive ink. Circuit 2 has two end terminals 3.

Une rondelle 4 est fixée par un rivet 5 sur chaque borne 3. Cha­que rondelle 4 est solidaire d'un fil de connexion 6. Les rondel­les 4 peuvent également être soudées ou collées. A son extrémité libre, le fil de connexion 6 est équipé d'une borne de connexion, par exemple une fiche mâle 7.A washer 4 is fixed by a rivet 5 on each terminal 3. Each washer 4 is secured to a connection wire 6. The washers 4 can also be welded or glued. At its free end, the connection wire 6 is equipped with a connection terminal, for example a plug 7.

Une plaque isolante 8 est collée sur le support 1 et comporte un canal 9 en forme de Y. Les extrémités des branches du canal 9 sont terminées par un bossage 10 enfermant la connexion entre la rondel­le 4 et la borne 3. Les fils 6 sont logés chacun dans une branche du canal 9 et sont côte à côte dans le pied du canal 9.An insulating plate 8 is bonded to the support 1 and comprises a Y-shaped channel 9. The ends of the branches of the channel 9 are terminated by a boss 10 enclosing the connection between the washer 4 and the terminal 3. The wires 6 are housed each in a branch of channel 9 and are side by side in the foot of channel 9.
