Abstract

The invention relates to an electrical screw socket device enabling significant simplifications to be made concerning, on the one hand, the structure of the product and, on the other hand, the procedure relative to fitting and unfitting the latter. The device comprises only two parts: a cap-casing 1 and a connection disc 2 which are locked by means of an internal circlip 3. This device may be applied to all types of screw-cap light bulbs meeting the various known standards.

Description

La présente invention concerne an dispositif de douille électrique à vis, qui apporte des simplifications portant, d'ane part, sur la structure du produit, et, d'autre part, sur le mode opératoire relatii à la pose ou le démontage de celui-ci. The present invention relates to an electric screw socket device, which provides simplifications relating, on the one hand, to the structure of the product, and, on the other hand, to the operating method relating to the installation or dismantling of the latter. this.

Traditionnellement, les douilles électriques à vis, com portent trois, voire, autre pièces principales : an cuolot, une chemise (lisse ou filetée), un fourreau dileté extérieurement, et une pastille de raccordement,
Cetts pastille permet généralement de connecrter les conduoteurs, préalablement dénudés en bout, à l'aide de bornes à vis reliéews sux contscts faisant fonctionner l'ampoule.Traditionally, electric screw sockets have three or more other main parts: in the cup, a jacket (smooth or threaded), an externally diluted sheath, and a connection pad,
This patch generally makes it possible to connect the conductors, previously stripped at the end, using screw terminals connected to sux contscts operating the bulb.

En ce qui concerna les modes de connexions, parmi les dis- positife existante, on peut noter aussi, que l'un dispose de languettes métalliques élastiquement déformables, l'autre d'enccches, celui-ci ne nécessitant pas de dénudage préalable des houts de conductours. With regard to the modes of connection, among the existing devices, it can also be noted that one has elastically deformable metal tongues, the other has hooks, the latter not requiring prior stripping of the houts. of conductours.

Le dispositif selon l'invention permet, simyltanément, de réduire, d'une part, la nombre de pièces compesant le douille, et d'autre part, les temps de pese ou démontage,
Contrairement aux produite existants, chemise (lisse ou filetée) et culit ne forment plus qu'une pièce unique; par aillsurs, la pastille de connexion, cumule de sucroft deux amtren fanetions s d'abord, séparation des conducteurs et arrêt du câble, ensuite, fixation du conductsur de prise de terre,
La pastille de connexion qui s'emboite dans la chemise-culot esf bloqués an moyen d'un circlip intérieur (à sectiction rectangulaire ou circulaire), ou, de pattes élastiques.The device according to the invention makes it possible, simultaneously, to reduce, on the one hand, the number of parts making up the bushing, and on the other hand, the weighing or dismantling times,
Unlike the existing products, the shirt (smooth or threaded) and culit no longer form a single piece; by aursurs, the connection pad, cumulates sucroft two amtren flags first, separation of the conductors and cable stop, then, fixing of the conductor on earth
The connection pad which fits into the shirt-base is blocked by means of an internal circlip (with rectangular or circular section), or, elastic tabs.
