Description
La présente invention concerne une douille, spécialement pour lampes de bureau et appliques.The present invention relates to a socket, especially for desk lamps and wall lamps.
Sont connus dépuis longtemps différents modéles de douille, comprenants un corps principal ayant structure fondamentallement tubulaire, avec un filetage intérieur pour engager le socle filetté d'une ampoule, et apte à délimiter des logements convenables pour un insert qui supporte les contacts électriques pour l'alimentation de l'ampoule, et pour les moyens de blocage de la gaine qui revêt et unit les conducteurs réliés aux précités contacts: ledit corps tubulaire étant en un seul élément réalisé par moulage de matériel plastique artificiel.Different models of socket have been known for a long time, comprising a main body having a fundamentally tubular structure, with an internal thread for engaging the threaded base of a bulb, and capable of delimiting suitable housings for an insert which supports the electrical contacts for the supply of the bulb, and for the means for blocking the sheath which covers and unites the conductors connected to the aforementioned contacts: said tubular body being in a single element produced by molding of artificial plastic material.
Mais, justement pour le fait de présenter le corps principal en un seul élément, ces modéles de douille résultent di fabrication relativement longue et coûteuse par rapport aux exigences actuelles de production. En outre, ce-ci ne permet pas le montage automatique des contacts métalliques associés à l'insert de la douille, pour l'inaccessibilité de la cavité de son corps principal aux moyens prédisposés au montage et aux moyens préposés au câblage des respectifs conducteurs.But, precisely for the fact of presenting the main body in a single element, these socket models result from relatively long and costly manufacture compared to current production requirements. In addition, this does not allow automatic mounting of the metal contacts associated with the insert of the socket, for the inaccessibility of the cavity of its main body to the means predisposed for mounting and to the means used for wiring the respective conductors.
Le but principal de la présente invention est celui d'éliminer les précités incovenients et de proposer une douille de fabrication plus simple et économique, et qui soit de très grande fiabilité et sécurité.The main aim of the present invention is that of eliminating the aforementioned disadvantages and of proposing a simpler and more economical manufacturing socket, which is very reliable and safe.
A ce résultat on est parvenus, conformément à l'invention, en adoptant l'idée de réaliser une douille, spécialement pour lampes électriques de bureau et appliques, avec un corps principal fondamentalement cylindrique, en deux éléments en forme de coque fondamentalement symétriques entre eux, de manière à délimiter inférieurement, dans la position d'assemblage, un siège pour le vissage du socle de l'ampoule et un siège pour un insert qui supporte les deux contacts métalliques réliés aux conducteurs électriques pour l'alimentation de l'ampoule, où lesdits éléments en coque sont rendus étroitement solidaires, en correspondance à un plan diamétral de la douille, au moyen d'un élément annulaire envellopant la portion inférieure des deux éléments en coque adhérents au plan de jonction: ledit élément annulaire étant pourvu intérieurement de plusieurs saillies longitudinales capables de comprimer la correspondnate portion des deux éléments en coque et ainsi rendre de dimensions stables le siège pour le socle de l'ampoule dans la phase de vissage de la même, et chacun des deux éléments en coque étant pourvu des plusieures appendices flexibles et élastiques, avec l'extremité libre centripètement orientée vers la concavité de la demi-coque, de manière à s'engager avec accrochage irréversible dans un correspondant siège dudit élément annulaire avec un léger forcément élastique.
Avantegeusement, conformément à l'invention, ledit siège pour le logement de l'insert déstiné à supporter les contacts métalliques pour l'alimentation de l'ampoule, est délimité par deux cannaux fondamentalement semi-circulaires, symétriques par rapport au plan de jonction desdits deux éléments en coque et appartenants a ces-ci, et l'intérieur desquels est déstiné à se placer le bord de l'insert, de manière à resulter, avec les éléments en coque adhérents, dans un plan fondamentalement orthogonal à l'axe longitudinal central de la douille.This result has been achieved, in accordance with the invention, by adopting the idea of making a socket, especially for electric desk and wall lamps, with a fundamentally cylindrical main body, in two shell-shaped elements fundamentally symmetrical to each other. , so as to delimit below, in the assembly position, a seat for screwing the base of the bulb and a seat for an insert which supports the two metal contacts connected to the electrical conductors for supplying the bulb, wherein said shell elements are made tightly attached, in correspondence to a diametral plane of the sleeve, by means of an annular element enveloping the lower portion of the two shell elements adhering to the junction plane: said annular element being provided internally with several longitudinal projections capable of compressing the corresponding portion of the two shell elements and thus i make the seat for the base of the bulb stable dimensions in the screwing phase of the same, and each of the two shell elements being provided with several flexible and elastic appendages, with the free end centripetally oriented towards the concavity of the half-shell, so as to engage with irreversible latching in a corresponding seat of said annular element with a slight necessarily elastic.
Advantageously, in accordance with the invention, said seat for housing the insert intended to support the metal contacts for feeding the bulb, is delimited by two basically semicircular channels, symmetrical with respect to the junction plane of said two shell elements and belonging thereto, and the interior of which is intended to place the edge of the insert, so as to result, with the adherent shell elements, in a plane fundamentally orthogonal to the longitudinal axis center of the socket.
Les avantages qui dérivent de la présente invention consistent essentiellement en ce qu'il est possible de réaliser une douille de manière simple, rapide, stable et sure, en permettant le positionnement automatique de l'insert dans le respectif siège et le montage automatique des correspondants contacts métalliques, avec l'aide de moyens automatiques opportunement prédisposés dans la ligne de fabrication de la douille; que l'accrochage des deux éléments en coque de la douille à l'anneau de enraiement est irreversible, et donc il en permet l'utilisation dans un maximum de sicurité d'exercice; que ledit anneau de enraiement des deux éléments en coque de la douille est conformé de manière à conferir une grande résistance mécanique à la portion inférieure desdits éléments, ainsi de en empêcher l'éloignement réciproque en phase de vissement du socle de l'ampoule et rendre de dimensions stables le siège pour le socle; qu'il est possible conformer lesdits éléments en coque de manière à y intégrer des moyens de blocage du câble qui porte les conducteurs électriques; qu'une douille conformément à l'invention est de fabrication relativement simple, étant prevu le moulage separé des deux éléments en coque du corps principal, et très fiable méme après un temps prolongé d'exercice.The advantages deriving from the present invention essentially consist in the fact that it is possible to produce a socket in a simple, rapid, stable and secure manner, by allowing the automatic positioning of the insert in the respective seat and the automatic mounting of the corresponding metal contacts, with the help of automatic means conveniently arranged in the production line of the socket; that the attachment of the two shell elements of the bushing to the ring is irreversible, and therefore it allows the use thereof in maximum safety of exercise; that said ring of containment of the two shell elements of the socket is shaped so as to confer great mechanical resistance on the lower portion of said elements, thus preventing their reciprocal distancing in the screwing phase of the base of the bulb and rendering of stable dimensions the seat for the base; it is possible to conform said shell elements so as to integrate means for blocking the cable carrying the electrical conductors; that a socket according to the invention is relatively simple to manufacture, being provided for separate molding of the two shell elements of the main body, and very reliable even after an extended period of exercise.

Lesdits éléments en coque (1,2) sont rendu étroitement solidaires, en correspondance d'un plan longitudinal central (k-k) de la douille (P), au moyen d'un élément annulaire (6) enveloppant la portion inférieure (10,20) des deux éléments en coque (1,2) adhérent dans le plan de jonction (k-k). Ledit élément annulaire(6) est pourvu intérieurement de plusieurs sailles longitudinales (60) capables de comprimer la correspondante portion inférieure (10,20) des deux éléments en coque (1,2) et ainsi rendre de dimensions stables le siège (3) pour le socle de l'ampoule en phase de vissage de la même: Chacun des deux éléments en coque (1,2) est pourvu de deux appendices flexibles et elastiques (11,21), verticalement proéminentes d'une saillie horizontale (100,200) de la coque, et avec l'extremité libre (110,220) centripètement orientée vers la respective portion inférieure (10,20), de manière à s'engager avec accrochage irreversible dans un correspondant siège (61) dudit élément annulaire (6) avec un léger forcement elastique.Reduced to its essential structure and with reference to the figures of the appended drawings, a socket made of artificial plastic material according to the invention comprises a main body which is basically cylindrical, made of two shell elements (1,2) which are basically symmetrical with one another, so as to delimit below, in the assembled position, a seat (3) for screwing the base of a bulb and a seat for the insert (4) which supports the two metal contacts (5) connected to the electrical conductors for supplying the bulb. Said shell elements (1,2) are made closely integral, in correspondence with a central longitudinal plane (kk) of the sleeve (P), by means of an annular element (6) enveloping the lower portion (10,20 ) of the two shell elements (1,2) adhering in the junction plane (kk). Said annular element (6) is provided internally with several longitudinal projections (60) capable of compressing the corresponding lower portion (10,20) of the two shell elements (1,2) and thus making the seat (3) of stable dimensions for the base of the bulb in the screwing phase of the same: Each of the two shell elements (1,2) is provided with two flexible and elastic appendages (11,21), vertically prominent with a horizontal projection (100,200) of the shell, and with the free end (110,220) centripetally oriented towards the respective lower portion (10,20), so as to engage with irreversible hooking in a corresponding seat (61) of said annular element (6) with a slight necessarily elastic.
Avantageusement, conformément à l'invention,ledit siège pour le logement de l'insert (4) est délimité par deux cannaux (12,21) fondamentalement semi-circulairs, symétriques par rapport au plan de jonction desdits éléments en coque (1,2), et à leur tour délimités par des saillies (120,220) de la paroie intérieure des éléments (1,2), et à l'intérieur desquels est déstiné à se placer le bord de l'insert (4), de manière à resulter, dans la position d'éléments (1,2) adhérents, dans un plan fondamentalement othogonal à l'axe longitudinal central (r-r) de la douille.Advantageously, in accordance with the invention, said seat for housing the insert (4) is delimited by two channels (12,21) which are basically semi-circular, symmetrical with respect to the junction plane of said shell elements (1,2 ), and in turn delimited by projections (120,220) of the inner wall of the elements (1,2), and inside which is intended to place the edge of the insert (4), so as to result, in the position of adherent elements (1,2), in a plane basically othogonal to the central longitudinal axis (rr) of the socket.
