Description

La présente invention concerne un support pour douille de lampe halogène et le dispositif correspondant pour bloquer les deux conducteurs d'alimentation.The present invention relates to a support for a halogen lamp socket and the corresponding device for blocking the two supply conductors.

Il est connu que jusqu'à aujourd'hui, les lampes halogènes prévoient un support en porcelaine avec les bornes des conducteurs d'alimentation, libres à l'intérieur de l'enveloppe et les conducteurs correspondants pincés.
Cette disposition nécessite le blocage des bornes des conducteurs unipolaires en amont de la pince afin d'empêcher que, lors de l'extraction de la lampe et/ou du réflecteur, on n'entra ne les conducteurs en les enlevant de la pince.It is known that until today, halogen lamps provide a porcelain support with the terminals of the supply conductors, free inside the envelope and the corresponding pinched conductors.
This arrangement necessitates the blocking of the terminals of the unipolar conductors upstream of the clamp in order to prevent that, during the extraction of the lamp and / or the reflector, the conductors are not entered by removing them from the clamp.

La présente invention a pour principal but d'éliminer cet inconvénient.
Ce résultat a été atteint conformément à l'invention en réalisant un support pour la douille d'une lampe halogène comprenant un corps avec deux pattes parallèles, identiques, creuses, dans les cavités desquelles sont destinées à se loger, avec un forcement élastique, deux vis autotaraudeuses et portant la douille, avec ou sans l'interposition d'un réflecteur, et un appendice, disposé transversalement à une desdites pattes, avec une concavité et un trou traversant dans lequel un goujon de profil correspondant est fixé au moyen d'une vis autotaraudeuse et avec l'interposition des deux conducteurs d'alimentation de la lampe.The main object of the present invention is to eliminate this drawback.
This result was achieved in accordance with the invention by providing a support for the socket of a halogen lamp comprising a body with two parallel, identical, hollow legs, in the cavities of which are intended to be housed, with an elastic forcing, two self-tapping screws and carrying the sleeve, with or without the interposition of a reflector, and an appendage, arranged transversely to one of said legs, with a concavity and a through hole in which a stud of corresponding profile is fixed by means of a self-tapping screw and with the interposition of the two supply conductors of the lamp.

Selon une autre caractéristique de l'invention, ledit corps est pourvu d'une troisième patte, avec trou borgne, parallèle et surélevée par rapport aux deux premières et avec l'embouchure orientée du côté opposé, dont la cavité est destinée à recevoir, avec un forcement élastique, une vis autotaraudeuse de fixation d'un écran de la lampe.According to another characteristic of the invention, said body is provided with a third tab, with blind hole, parallel and raised relative to the first two and with the mouth oriented on the opposite side, the cavity of which is intended to receive, with an elastic forcing, a self-tapping screw for fixing a lamp screen.

Selon une autre caractéristique de l'invention, ledit corps est pourvu d'un trou parallèle auxdites pattes et fileté pour permettre le passage des conducteurs et la fixation du corps à une tige de l'appareil d'éclairage.According to another characteristic of the invention, said body is provided with a hole parallel to said legs and threaded to allow the passage of the conductors and the fixing of the body to a rod of the lighting fixture.

Les avantages obtenus grace à l'invention consistent essentiellement en ce que la douille est fixée au support au moyen de deux vis autotaraudeuses; qu'une seule vis autotaraudeuse permet le blocage simultané des deux conducteurs d'alimentation; que ledit blocage est situé à proximité des bornes; que tous les composants sont réalisés en PPS suivant le procédé du moulage; que le dispositif réalisé conformément à l'invention est d'application facile et rapide et de très grande fiabilité même après une longue période de fonctionnement.The advantages obtained by virtue of the invention essentially consist in that the socket is fixed to the support by means of two self-tapping screws; that a single self-tapping screw allows the simultaneous blocking of the two supply conductors; that said blocking is located near the terminals; that all components are made of PPS according to the molding process; that the device produced in accordance with the invention is easy and quick to apply and very reliable even after a long period of operation.
