Description

DOUILLE POUVANT RECEVOIR DES LAMPES A CULOT A SOCKET WHICH CAN RECEIVE BULB LAMPS A
VIS ET À BAÏONNETTESCREW AND BAYONET
La présente invention se rapporte à une douille pouvant recevoit indifféremment des lampes à culot à vis et des lampes à culot à baïonnette.The present invention relates to a socket which can receive either screw base lamps and bayonet base lamps.
A l'heure actuelle, les douilles utilisées notamment pour des lampes d'éclairage sont conçues pour recevoir, soit des culots à vis, soit des culots à baïonnette. Si certains pays ont adopté d'une manière générale l'un de ces deux systèmes, le plus souvent le système à vis, il existent des pays dans lesquels les deux systèmes sont utilisés simultanément. Tel est le cas pour la France qui utilise les culots à baïonnette du type B22, mais également B15 pour la lustrerie, et les culots à vis du type Edison E27, mais également Goliath E40 et Petit Edison E14.At present, the sockets used in particular for lighting lamps are designed to receive either screw caps or bayonet caps. While some countries have generally adopted one of these two systems, most often the screw system, there are countries in which both systems are used simultaneously. This is the case for France which uses bayonet caps of type B22, but also B15 for chandeliers, and screw caps of type Edison E27, but also Goliath E40 and Petit Edison E14.
Les culots à baïonnette comportent deux plots de contact diamétralement opposés sur leur fond, tandis que les culots à vis comportent un plot de contact central sur leur fond et une zone de contact latérale située au niveau de l'enveloppe métallique constituant le filetage du culot. Les douilles à baïonnette et les douilles à vis sont conformées pour pouvoir recevoir respectivement les culots à vis ou les culots à baïonnette et établir deux contacts électriques avec les éléments de contact de ces culots.The bayonet caps have two diametrically opposite contact pads on their bottom, while the screw caps have a central contact pad on their bottom and a lateral contact zone located at the metal casing constituting the thread of the cap. The bayonet sockets and the screw sockets are shaped so as to be able respectively to receive the screw caps or the bayonet caps and to establish two electrical contacts with the contact elements of these caps.
Les culots à vis et les culots à baïonnette sont normalisés. Ainsi, les culots à vis E22 présentent un diamètre maximal de 26 mm et une hauteur de 27 mm, tandis que les culots à baïonnette B22 présentent un diamètre de 22mm (diamètre du corps de culot, non compris les ergots de baïonnette) et une hauteur de 22 mm pour les culots sans collerette et de 25,5 mm pour les culots à collerette.Screw caps and bayonet caps are standardized. Thus, the E22 screw caps have a maximum diameter of 26 mm and a height of 27 mm, while the B22 bayonet caps have a diameter of 22mm (diameter of the cap body, not including the bayonet pins) and a height 22 mm for caps without flange and 25.5 mm for flange caps.
Il va de soi que l'utilisation de plusieurs types de culots et de douilles provoque un surcoût du point de vue fabrication, stockage et vente pour les lampes et pour les douilles, et entraîne également des problèmes pour les utilisateurs.It goes without saying that the use of several types of caps and sockets causes an additional cost from the point of view of manufacture, storage and sale for the lamps and for the sockets, and also causes problems for the users.
Il serait donc souhaitable, tant pour les fabricants de lampes et de douilles que pour les utilisateurs, de pouvoir disposer de douilles susceptibles de recevoir indifféremment des culots à vis et des culots à douille. La présente invention vise précisément une douilleIt would therefore be desirable, both for the manufacturers of lamps and sockets and for the users, to be able to have sockets capable of receiving either screw caps and socket caps. The present invention specifically relates to a socket
"universelle", c'est-à-dire une douille capable de recevoir aussi bien des lampes à culot à vis, notamment du type E27, que des lampes à culot à baïonnette, notamment du type B22."universal", that is to say a socket capable of receiving both screw base lamps, in particular of the E27 type, as well as bayonet base lamps, in particular of the B22 type.
La douille conforme à l'invention comprend un manchon isolant présentant intérieurement dans sa partie supérieure un filetage capable de recevoir le filetage d'un culot à vis et deux rainures axiales diamétralement opposées débouchant en dessous dudit filetage dans deux encoches pour le passage et le verrouillage des ergots d'un culot à baïonnette. La douille comprend, de plus, au moins trois éléments de contact comprenant un élément de contact latéral s'etendant à l'intérieur du manchon de bas en haut jusqu'à la base du filetage, pour coopérer avec la zone de contact latérale d'un culot à vis, les autres éléments de contact étant situés à l'intérieur du manchon de manière à pouvoir coopérer avec le plot de contact central du culot à vis et avec les plots de contact du fond d'un culot à baïonnette, l'un desdits autres éléments de contact étant monté mobile axialement et conformé de manière à ne pas être sollicité par un culot à vis engagé dans la douille et à établir une liaison électrique avec ledit élément de contact latéral lorsqu'il n'est pas sollicité, et à interrompre ladite liaison électrique lorsqu'il est sollicité par un culot à baïonnette engagé dans la douille.The socket according to the invention comprises an insulating sleeve having internally in its upper part a thread capable of receiving the thread of a screw base and two diametrically opposite axial grooves emerging below said thread in two notches for passage and locking lugs of a bayonet cap. The socket further comprises at least three contact elements comprising a lateral contact element extending inside the sleeve from bottom to top up to the base of the thread, to cooperate with the lateral contact zone of a screw base, the other contact elements being located inside the sleeve so as to be able to cooperate with the central contact pad of the screw base and with the contact pads of the bottom of a bayonet base, the one of said other contact elements being mounted axially movable and shaped so as not to be stressed by a screw base engaged in the socket and to establish an electrical connection with said lateral contact element when it is not stressed, and to interrupt said electrical connection when it is requested by a bayonet fitting engaged in the socket.
De préférence, ledit autre élément de contact mobile comprend une broche de contact qui est montée mobile en translation axiale, qui porte une lamelle transversale faisant saillie latéralement et qui est sollicitée par un ressort de rappel dans la position dans laquelle ladite lamelle établit la liaison électrique avec ledit élément de contact latéral.Preferably, said other movable contact element comprises a contact pin which is mounted movable in axial translation, which carries a transverse lamella projecting laterally and which is biased by a return spring in the position in which said lamella establishes the electrical connection with said element lateral contact.
Suivant un mode de réalisation, la douille comporte, en plus de l'élément de contact latéral, deux éléments de contact comprenant ledit autre élément de contact mobile susceptible de coopérer avec un plot de contact d'un culot à baïonnette engagé dans la douille, et un élément de contact également mobile axialement positionné de manière à pouvoir coopérer aussi bien avec l'autre plot de contact du culot à baïonnette qu'avec le plot de contact central d'un culot à vis engagé dans la douille. Suivant un autre mode de réalisation, la douille comporte, en plus de l'élément de contact latéral, trois éléments de contact comprenant ledit autre élément de contact mobile susceptible de coopérer avec un plot de contact d'un culot à baïonnette engagé dans la douille, et deux éléments de contact positionnés de manière à pouvoir coopérer l'un avec l'autre plot de contact du culot à baïonnette et l'autre avec le plot de contact central d'un culot à vis engagé dans la douille.According to one embodiment, the socket comprises, in addition to the lateral contact element, two contact elements comprising said other movable contact element capable of cooperating with a contact pad of a bayonet base engaged in the socket, and a contact element also axially movable positioned so as to be able to cooperate both with the other contact pad of the bayonet base and with the central contact pad of a screw base engaged in the socket. According to another embodiment, the socket comprises, in addition to the lateral contact element, three contact elements comprising said other movable contact element capable of cooperating with a contact pad of a bayonet base engaged in the socket , and two contact elements positioned so as to be able to cooperate, one with the other contact pad of the bayonet base and the other with the central contact pad of a screw base engaged in the socket.
Dans ce cas, l'élément de contact coopérant avec le plot de contact central du culot à vis peut être un élément de contact mobile conformé de manière à être alimenté par l'élément de contact coopérant avec ledit autre plot de contact du culot à baïonnette, uniquement lorsqu'il est sollicité par un culot à baïonnette engagé dans la douille.In this case, the contact element cooperating with the central contact pad of the screw base can be a movable contact element shaped so as to be powered by the contact element cooperating with said other contact pad of the bayonet cap. , only when requested by a bayonet fitting engaged in the socket.
En se référant aux dessins schématiques annexés, on va décrire ci-après plus en détail deux modes de réalisation d'une douille conforme à l'invention. Sur les dessins:Referring to the appended schematic drawings, two embodiments of a socket according to the invention will be described below in more detail. In the drawings:
-la figure 1 est une coupe axiale d'une douille après engagement d'une lampe à culot à baïonnette;FIG. 1 is an axial section of a socket after engagement of a bayonet base lamp;
-la figure 2 est une coupe axiale de la douille de la figure 1 après engagement d'une lampe à culot à vis;FIG 2 is an axial section of the socket of Figure 1 after engagement of a screw base lamp;
-la figure 3 est une coupe axiale d'un autre mode de réalisation d'une douille après engagement d'une lampe à culot à baïonnette;FIG. 3 is an axial section of another embodiment of a socket after engagement of a bayonet base lamp;
-la figure 4 est une coupe axiale de la douille de la figure 3 après engagement d'une lampe à culot à vis. La douille selon les figures 1 et 2, destinée à pouvoir recevoir indifféremment des ampoule à baïonnette du type B22 et des ampoules à vis du type E27, comprend un manchon 1 en matière isolante, par exemple en matière plastique, présentant intérieurement dans sa partie supérieure un filetage capable de recevoir le filetage d'un culot à vis visible sur la figure 2, ainsi que deux rainures axiales 4 diamétralement opposées permettant le passage des ergots d'un culot à baïonnette selon la figure 1, ces rainures débouchant en dessous du filetage dans des encoches de verrouillage pour lesdits ergots. Le manchon 1 présente par ailleurs intérieurement, en dessous du filetage, une rainure axiale 3 dans laquelle est fixée une lame métallique 2 de manière à déborder sur la dernière spire du filetage et à laisser dégagée la partie inférieure de la rainure 3.FIG 4 is an axial section of the socket of Figure 3 after engagement of a screw base lamp. The socket according to FIGS. 1 and 2, intended to be able to receive indifferently bayonet bulbs of type B22 and screw bulbs of type E27, comprises a sleeve 1 made of insulating material, for example plastic, having internally in its upper part a thread capable of receiving the thread of a screw base visible in FIG. 2, as well as two diametrically opposite axial grooves 4 allowing the lugs of a bayonet base according to FIG. 1 to pass, these grooves opening out below the thread in locking notches for said pins. The sleeve 1 also has internally, below the thread, an axial groove 3 in which a metal blade 2 is fixed so as to extend beyond the last turn of the thread and leave the lower part of the groove 3 free.
La douille comprend, par ailleurs, un bloc 14 en matière isolante, maintenu dans une enveloppe 23 en matière isolante qui est vissée sur la partie inférieure du manchon 1 et fermée dans le bas par un fond 22 comportant un trou pour le passage des fils électriques de branchement, non représentés. Le bloc 14 comporte en partie basse, pour le raccordement de ces fils, deux bornes à vis 20 et 21 qui se prolongent vers le haut sous la forme de deux fourreaux dans lesquels des broches 10 et 15 sont montées de manière à dépasser vers le haut. Chaque broche 10, 15 mobile en translation axiale dans son fourreau est sollicitée élastiquement vers le haut par un ressort de compression intercalé entre le broche et le fond de son fourreau. Les deux broches 10 et 15 sont positionnées de part et d'autre de l'axe de la douille de manière à pouvoir coopérer avec les deux plots de contact prévus sur le fond d'un culot à baïonnette engagé dans la douille, en étant légèrement enfoncées dans leurs fourreaux lorsque le culot à baïonnette est verrouillé dans la douille (position représentée sur la figure 1).The socket further comprises a block 14 of insulating material, held in an envelope 23 of insulating material which is screwed onto the lower part of the sleeve 1 and closed at the bottom by a bottom 22 having a hole for the passage of electrical wires of connection, not shown. The block 14 comprises in the lower part, for the connection of these wires, two screw terminals 20 and 21 which extend upwards in the form of two sleeves in which pins 10 and 15 are mounted so as to protrude upwards . Each spindle 10, 15 movable in axial translation in its sheath is elastically urged upwards by a compression spring interposed between the spindle and the bottom of its sheath. The two pins 10 and 15 are positioned on either side of the axis of the socket so as to be able to cooperate with the two contact pads provided on the bottom of a bayonet fitting engaged in the socket, being slightly pressed into their sleeves when the bayonet cap is locked in the socket (position shown in Figure 1).
La broche 10 porte, au-dessus du bloc 14, une lamelle 11 transversale métallique dont l'extrémité libre est guidée dans la partie inférieure dégagée de la rainure 3 du manchon 1. Lorsque la broche 10 n'est pas sollicitée, c'est-à-dire enfoncée, situation qui existe lors de l'engagement d'un culot à vis dans la douille, selon la figure 2, la lamelle 11 de la broche est appliquée contre l'extrémité inférieure de la lame 2, de sorte que la lame se trouve au potentiel du fil raccordé à la borne 20. Par contre, lorsque la broche est sollicitée, c'est-à-dire enfoncée par le plot de contact d'un culot à baïonnette engagé dans la douille, selon la figure 1, la lamelle 11 est séparée de la lame 2 et cette dernière ne reçoit alors pas le potentiel du fil raccordé à la borne 20.The pin 10 carries, above the block 14, a metal transverse strip 11 whose free end is guided in the lower part released from the groove 3 of the sleeve 1. When the pin 10 is not stressed, it is that is to say, a situation which exists when engaging a screw base in the socket, according to FIG. 2, the lamella 11 of the spindle is applied against the lower end of the blade 2, so that the blade is at the potential of the wire connected to the terminal 20. On the other hand, when the spindle is stressed, that is to say pushed in by the contact pad of a bayonet fitting engaged in the socket, according to FIG. 1, the strip 11 is separated from the strip 2 and the latter then does not receive the potential of the wire connected to the terminal 20.
Entre les deux broches 10 et 15 destinées à coopérer aves les deux plots de contact d'un culot à baïonnette, le bloc 14 comporte une broche centrale 12 qui est également mobile en translation axiale de manière à pouvoir être enfoncée dans le bloc 14 à rencontre de l'action d'un ressort de rappel. Il est à noter que la broche 12 est reliée électriquement à la broche 15 par une platine métallique 16, cette liaison pouvant être telle qu'elle soit établie lorsque la broche centrale 12 est sollicitée par un culot à vis selon la figure 2, mais soit interrompue lorsque la broche 12 est sollicitée par un culot à baïonnette selon la figure 1.Between the two pins 10 and 15 intended to cooperate with the two contact pads of a bayonet base, the block 14 comprises a central pin 12 which is also movable in axial translation so as to be able to be pressed into the block 14 to meet the action of a return spring. It should be noted that pin 12 is electrically connected to pin 15 by a metal plate 16, this connection possibly being such that it is established when the central pin 12 is stressed by a screw base according to FIG. 2, but either interrupted when the pin 12 is biased by a bayonet cap according to FIG. 1.
Il ressort des figures 1 et 2 que lors de l'engagement d'une lampe à baïonnette dans la douille, ce sont les deux broches 10 et 15 qui assurent l'alimentation de la lampe, par les deux plots du fond du culot de la lampe, la liaison entre la lame 2 et la lamelle 11 étant interrompue par l'enfoncement de la broche 10, tandis que lors de l'engagement d'une lampe à vis, les deux broches 10 et 15 ne sont pas enfoncée, de sorte que l'alimentation de la lampe s'effectue latéralement au niveau du filetage du culot par la lame 2 reliée par la lamelle 11 de la broche 10 à la borne 20 et de façon centrale par la broche 12 reliée par la platine 16 à la broche 15 elle-même reliée à la borne 21.It appears from Figures 1 and 2 that during the engagement of a bayonet lamp in the socket, it is the two pins 10 and 15 which supply the lamp, by the two studs at the bottom of the base of the lamp, the connection between the blade 2 and the strip 11 being interrupted by the insertion of the pin 10, while during the engagement of a screw lamp, the two pins 10 and 15 are not pressed, so that the lamp is supplied laterally at the thread of the base by the blade 2 connected by the strip 11 of the pin 10 to the terminal 20 and centrally by the pin 12 connected by the plate 16 to the pin 15 itself connected to terminal 21.
Dans le mode de réalisation illustré par les figures 3 et 4, on retrouve la structure générale déjà décrite pour le mode de réalisation des figures 1 et 2, les seules différences se situant au niveau des contacts au fond de la douille. La douille suivant cette variante reprend donc le manchon 1 avec son filetage, les rainures 4 et encoches de verrouillage des ergots de baïonnette, la rainure 3 pour la lame 2, l'enveloppe 23 et le fond 22, le bloc 14 isolant avec ses deux bornes à vis 20 et 21, ainsi que la broche de contact 10 qui coopère avec l'un des plots de contact d'un culot à baïonnette et porte la lamelle transversale 11 établissant la liaison électrique de la borne 20 avec la lame latérale 2 pour l'alimentation d'une lampe à vis. Par contre, le bloc 14 comporte, en plus de la broche 10, non pas deux broches supplémentaires (12 et 15) sur le fond de la douille, mais une seule broche 25 qui peut présenter un diamètre accru et est positionnée, par rapport à l'axe de la douille, de manière qu'elle puisse coopérer aussi bien avec l'un des plots de contact du fond d'un culot à baïonnette, selon la figure 3, qu'avec le plot central d'un culot à vis, selon la figure 4.In the embodiment illustrated by Figures 3 and 4, we find the general structure already described for the embodiment of Figures 1 and 2, the only differences being at the level of the contacts at the bottom of the socket. The socket according to this variant therefore takes up the sleeve 1 with its thread, the grooves 4 and locking notches of the bayonet lugs, the groove 3 for the blade 2, the casing 23 and the bottom 22, the insulating block 14 with its two screw terminals 20 and 21, as well as the contact pin 10 which cooperates with one of the contact pads of a bayonet base and carries the transverse strip 11 establishing the electrical connection of the terminal 20 with the side blade 2 for the power of a screw lamp. On the other hand, the block 14 comprises, in addition to the pin 10, not two additional pins (12 and 15) on the bottom of the socket, but a single pin 25 which may have an increased diameter and is positioned, with respect to the axis of the socket, so that it can cooperate as well with one of the contact pads on the bottom of a bayonet base, according to FIG. 3, as with the central stud of a screw base , according to figure 4.
Bien entendu, la broche 25, qui coopère à la fois avec des culots à baïonnette et avec des culots à vis, est également mobile en translation axiale à l'encontre d'un ressort de rappel, pour pouvoir compenser les différences de position en hauteur existant entre les plots de contact des culots à baïonnette et le plot de contact central des culots à vis engagés dans la même douille.Of course, the pin 25, which cooperates with both bayonet caps and with screw caps, is also movable in axial translation against a return spring, in order to be able to compensate for the differences in position in height existing between the contact pads of the bayonet caps and the central contact pad of the screw caps engaged in the same socket.
Il y a lieu de noter également que les broches de contact coulissantes utilisées à titre d'éléments de contact de fond sur la douille telle que décrite et représentée pourraient être remplacées dans le cadre de l'invention par d'autres contacts mobiles élastiquement. It should also be noted that the sliding contact pins used as bottom contact elements on the socket as described and shown could be replaced in the context of the invention by other elastically movable contacts.
