Abstract

The switch has a plastics housing receiving two L-shaped leaf contacts having their arms parallel. The upper arms are separated by a partition and connected to respective wires. The housing has an integral lower wall which extends around and above the free end of the lower limb of the outer contact with a spigot for contacting the limb end. The housing sits in the antitheft device containing a key board and key hole. When the key is inserted it depresses an upper extension of the spigot to depress the lower limb and break its resilient contact with the lower limb of the inner contact. The lid of the housing includes an eyelet which after being folded over the hinge cooperates with a protruding hook in order to lock the lid in a closed position.

Description

L'invention concerne un interrupteur électrique du type comprenant un bottier en matière thermoplastique contenant un jeu de lames de contact, un poussoir de commande d'au moins une lame de contact mobile portée par le boîtier, ledit poussoir étant rappelé élastiquement en position de repos de l'interrupteur, et un couvercle de fermeture du boîtier. The invention relates to an electrical switch of the type comprising a housing made of thermoplastic material containing a set of contact blades, a control button for at least one movable contact blade carried by the housing, said button being resiliently returned to the rest position. switch, and a housing closure cover.

De tels interrupteurs sont utilisés par exemple dans les antivols automobiles, la clé d'antivol agissant sur le poussoir pour actionner l'interrupteur et signaler ainsi, conjointement à d'autres conditions, la présence de la clé dans la serrure d'antivol. Such switches are used for example in automobile anti-theft devices, the anti-theft key acting on the pusher to actuate the switch and thus signal, together with other conditions, the presence of the key in the anti-theft lock.

Les interrupteurs connus de ce type sont d'une construction et d'un assemblage assez compliqués, ce qui leur donne un prix de revient élevé. Known switches of this type are of a rather complicated construction and assembly, which gives them a high cost price.

La présente invention vise à simplifier les interrupteurs du type décrit de manière à faciliter leur montage et réduire leur coût. The present invention aims to simplify the switches of the type described so as to facilitate their mounting and reduce their cost.

A cet effet, dans l'interrupteur selon l'invention, le poussoir est d'une seule pièce avec le boîtier et est relié à celui-ci par un bras élastiquement déformable. To this end, in the switch according to the invention, the pusher is in one piece with the housing and is connected to the latter by an elastically deformable arm.

De préférence, le couvercle est d'une seule pièce avec le boîtier et est relié à celui-ci par un film-charnière. Preferably, the cover is in one piece with the housing and is connected to the latter by a film hinge.

L'interrupteur selon l'invention comprend donc un nombre réduit de pièces, avec un boîtier formant en même temps poussoir élastique et, de préférence, couvercle. The switch according to the invention therefore comprises a reduced number of parts, with a housing forming at the same time an elastic plunger and, preferably, a cover.

La pièce unique en matière thermoplastique peut être moulée très simplement, ce qui diminue encore le prix de revient.The single piece of thermoplastic material can be molded very simply, which further reduces the cost price.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé. The invention will be clearly understood on reading the following description made with reference to the accompanying drawing.

dans lequel
- la figure 1 est une vue schématique en perspective des divers composants d'un interrupteur selon un exemple de réalisation de l'invention destiné à un antivol automobile, avant assemblage,
- la figure 2 est une vue en coupe radiale de l'interrupteur de la figure 1 monté sur un antivol, la clé étant retirée, et
- la figure 3 est analogue à la figure 2, la clé étant présente.in which
FIG. 1 is a schematic perspective view of the various components of a switch according to an exemplary embodiment of the invention intended for an automobile anti-theft device, before assembly,
FIG. 2 is a view in radial section of the switch in FIG. 1 mounted on an anti-theft device, the key being removed, and
- Figure 3 is similar to Figure 2, the key being present.

L'interrupteur comprend un boîtier 1 comprenant un logement 2 pour une lame de contact fixe 3 et un logement 4 pour une lame de contact mobile 5. Le boîtier 1 est prolongé par un bras élastique 6 terminé par un poussoir 7. A l'opposé de son extrémité libre, le poussoir 7 comporte un talon 8 coopérant avec l'extrémité libre de la lame de contact mobile 5. A l'opposé du brans 6, le boîtier 1 est prolongé par un couvercle 9, le boîtier 1 et le couvercle 9 étant d'une seule pièce et étant reliés par un film-charnière 10 formé par une rainure 11. Le couvercle 9 comporte un oeillet 12 qui, après pliage autour de la charnière 10, vient coopérer avec un crochet 13 qui fait saillie du boîtier 1, afin de verrouiller le couvercle en position de fermeture du boîtier (non représentée). The switch comprises a housing 1 comprising a housing 2 for a fixed contact blade 3 and a housing 4 for a movable contact blade 5. The housing 1 is extended by an elastic arm 6 terminated by a pusher 7. Opposite from its free end, the pusher 7 has a heel 8 cooperating with the free end of the movable contact blade 5. Opposite the brans 6, the housing 1 is extended by a cover 9, the housing 1 and the cover 9 being in one piece and being connected by a hinge film 10 formed by a groove 11. The cover 9 has an eyelet 12 which, after folding around the hinge 10, comes to cooperate with a hook 13 which projects from the housing 1, in order to lock the cover in the closed position of the housing (not shown).

L'interrupteur est logé dans un évidement 14 de la tête d'un antivol 15 qui comprend un barillet de serrure avec un canal de clé 17. Le poussoir 7 coulisse dans une fente radiale 18 faisant communiquer l'évidement 14 avec l'espace libre au-delà du barillet 16. En l'absence de la clé (figure 2), un palpeur de clé 19 pénètre dans le canal de clé 17 et n'agit pas sur le poussoir 7 qui reste à sa position de repos. Le talon 8 du poussoir ne repousse pas la lame de contact 5 et l'interrupteur reste fermé. The switch is housed in a recess 14 in the head of an anti-theft device 15 which comprises a lock barrel with a key channel 17. The pusher 7 slides in a radial slot 18 making the recess 14 communicate with the free space beyond the barrel 16. In the absence of the key (Figure 2), a key probe 19 enters the key channel 17 and does not act on the pusher 7 which remains in its rest position. The heel 8 of the pusher does not push back the contact blade 5 and the switch remains closed.

Au contraire, Si la clé 20 est dans le canal de clé 17, le palpeur 19 est repoussé hors du canal 17 et repousse le poussoir 7 dont le talon 8 écarte la lame de contact 5. L'interrupteur est donc ouvert. Dès que la clé 20 est sortie, le palpeur 19 est repousse élastiquement par le poussoir 7 et l'ensemble revient à la position de la figure 2.  On the contrary, If the key 20 is in the key channel 17, the feeler 19 is pushed out of the channel 17 and pushes the plunger 7 whose heel 8 spreads the contact blade 5. The switch is therefore open. As soon as the key 20 is out, the feeler 19 is resiliently pushed back by the pusher 7 and the assembly returns to the position of FIG. 2.

On notera que l'ensemble en matière thermoplastique, d'une seule pièce, qui constitue le boîtier 1, le bras 6 avec -son poussoir 7 et le couvercle 9 avec sa charnière 10 peut être moulé très facilement par coopération de deux demiempreintes de moule, sans mouvements en tiroirs.  It will be noted that the assembly made of thermoplastic material, in one piece, which constitutes the housing 1, the arm 6 with its push button 7 and the cover 9 with its hinge 10 can be molded very easily by cooperation of two mold half-impressions. , without movements in drawers.
