Description

La présente invention est relative à un connecteur électrique qui est particulièrement adapté à la réalisation de petites douilles notamment pour des guirlandes électriques.The present invention relates to an electrical connector which is particularly suitable for the production of small sockets, in particular for electric strings.

On entend par "petite douille" un ensemble constitué par une lampe, un porte-lampe supportant cette lampe et une qaine comprenant un noyau et deux connecteurs.The term "small socket" means an assembly consisting of a lamp, a lamp holder supporting this lamp and a qaine comprising a core and two connectors.

La décoration, par exemple des sapins ou des vitrines pour les fêtes de fin d'année, fait en particulier appel à des accessoires lumineux destinés à renforcer le côté féérique de cette période. Parmi les accessoires lumineux les plus couramment utilisés, seront notamment citées les guirlandes électriques : celles-ci ont maintenant presque totalement remplacé les traditionnelles bouqies dont l'utilisation fût et reste encore la cause de nombreux accidents à cette époque de l'année : incendies, brûlures d'enfants, notamment. Si l'emploi de guirlandes électriques paraît de prime abord ne pas être source de danqer, il doit néanmoins être rappelé qu'elles présentent tous les inconvénients des produits électriques : notamment il peut se produire des courts-circuits qui peuvent entraîner les mêmes conséquences que l'emploi de bougies et qui sont assez souvent dus à un échauffement anormalement élevé au niveau des petites douilles. Ce type d'accident peut avoir en particulier pour origine un montage incorrect des connecteurs électriques dans ces douilles.The decoration, for example of fir trees or shop windows for the end of year celebrations, calls in particular on luminous accessories intended to reinforce the magical side of this period. Among the most commonly used lighting accessories, electric garlands will be cited in particular: these have now almost completely replaced the traditional bouqies whose use was and still remains the cause of many accidents at this time of year: fires, burns of children, in particular. If the use of electric garlands seems at first glance not to be a source of danqer, it should nevertheless be remembered that they have all the disadvantages of electric products: in particular, short-circuits can occur which can have the same consequences as the use of candles and which are quite often due to an abnormally high temperature rise in the small sockets. This type of accident can in particular originate from an incorrect mounting of the electrical connectors in these sockets.

Aussi, un des buts de la présente inention est-il un connecteur électrique permettant d'éviter tout court- circuit dans la douille.Also, one of the aims of the present invention is an electrical connector making it possible to avoid any short circuit in the socket.

Un autre but de l'invention est un connecteur électrique dans lequel la fixation des pièces mâles ou broches d'un porte-lampe peut être assurée même en cas de tolérances importantes.Another object of the invention is an electrical connector in which the fixing of the male parts or pins of a lamp holder can be ensured even in the event of large tolerances.

Un objet de la présente invention est une petite douille comportant au moins deux tels connecteurs électriques, dont la pression de contact est indépendante des matériaux isolants utilisés pour la réalisation de cette douille.An object of the present invention is a small socket comprising at least two such electrical connectors, the contact pressure of which is independent of insulating materials used for the production of this socket.

Ces buts et cet objet, ainsi que d'autres qui apparaîtront par la suite, sont atteints par une douille électrique selon la présente invention qui comprend une gaine extérieure sensiblement cylindrique, et ouverte à ses deux extrémités, un noyau sensiblement cylindrique comportant au moins deux encoches pour le logement de deux connecteurs électriques, ce noyau et ces connecteurs étant situés à l'intérieur de la douille et maintenus en position par tout moyen convenable, et un porte-lampe.These aims and this object, as well as others which will appear subsequently, are achieved by an electric socket according to the present invention which comprises a substantially cylindrical outer sheath, and open at its two ends, a substantially cylindrical core comprising at least two notches for housing two electrical connectors, this core and these connectors being located inside the socket and kept in position by any suitable means, and a lamp holder.

Avantageusement, un connecteur électrique est constitué d'une partie verticale comportant à une extrémité au moins une virole de sertissage, à son autre extrémité un manchon cylindrique, et, entre ces deux extrémités, deux éléments de blocage situés de part et d'autre de la partie verticale.Advantageously, an electrical connector consists of a vertical part comprising at one end at least one crimping ferrule, at its other end a cylindrical sleeve, and, between these two ends, two blocking elements located on either side of the vertical part.

De préférence, le manchon cylindrique est constitué par deux branches sensiblement hémi-cylindriques, séparées l'une de l'autre par une fente.Preferably, the cylindrical sleeve is constituted by two substantially semi-cylindrical branches, separated from each other by a slot.

Avantageusement, la partie verticale du connecteur électrique comporte deux viroles de sertissage.Advantageously, the vertical part of the electrical connector comprises two crimping ferrules.

De préférence, la partie verticale ainsi que ses éléments de blocage sont léqèrement courbés par rapport à leur plan médian.Preferably, the vertical part and its blocking elements are slightly curved with respect to their median plane.

Quant au noyau, il comporte deux encoches symétriquement opposées dans lesquelles sont loqés les connecteurs électriques.As for the core, it has two symmetrically opposite notches in which the electrical connectors are locked.

Avantageusement, une encoche comprend une découpe supérieure pour le manchon cylindrique dont le sommet affleure celui du noyau, une découpe inférieure pour le logement de la partie inférieure du connecteur électrique ainsi que du fil électrique duquel il est solidaire, et une partie intermédiaire pour les éléments de blocage.Advantageously, a notch includes an upper cutout for the cylindrical sleeve whose apex is flush with that of the core, a lower cutout for housing the lower part of the electrical connector as well as the electrical wire from which it is integral, and an intermediate part for the elements. blocking.

De préférence, chaque connecteur électrique est bloqué, d'une part, par ses éléments de blocage situés dans le logement intermédiaire, et, d'autre part, par le fait que sa oartie verticale est coincée entre le noyau et l'intérieur de la gaine extérieure.Preferably, each electrical connector is blocked, on the one hand, by its blocking elements located in the intermediate housing, and, on the other hand, by the fact that its vertical part is wedged between the core and the interior of the outer sheath.

The description which follows and which does not include any limiting character must be read with reference to the appended figures, among which:
  • Figure 1 shows a socket according to the present invention provided with a lamp;
  • FIG. 2 represents, in perspective view, the various elements of the object of FIG. 1 as well as their position with respect to each other:

Nous supposerons que la douille ainsi que les connecteurs électriques sont disposés verticalement comme représenté sur les figures, ce qui donne un sens aux termes tels que "supérieur", "inférieur" ou "latéral" qui seront employés ci-après.We will assume that the socket and the electrical connectors are arranged vertically as shown in the figures, which gives meaning to terms such as "upper", "lower" or "lateral" which will be used below.

Ainsi qu'on peut le voir notamment sur les fiqures 1 et 2, une douille selon la présente invention, désignée par le repère 1 dans son ensemble, comprend une gaine extérieure 2, dans laquelle est situé un noyau 3 ainsi qu'au moins deux connecteurs électriques 4 et 5. Un porte-lampe 6 peut être monté sur une telle douille 1.As can be seen in particular in FIGS. 1 and 2, a socket according to the present invention, designated by the reference 1 as a whole, comprises an outer sheath 2, in which is located a core 3 as well as at least two electrical connectors 4 and 5. A lamp holder 6 can be mounted on such a socket 1.

La gaine extérieure 2 est sensiblement cylindrique et ouverte à ses deux extrémités. La partie inférieure de cette gaine 2 peut être tronconique, c'est-à-dire se rétrécir en direction de l'extrémité inférieure pour des raisons qui sont exposées plus loin.The outer sheath 2 is substantially cylindrical and open at its two ends. The lower part of this sheath 2 can be frustoconical, that is to say to narrow towards the lower end for reasons which are discussed below.

Le noyau 3 est également sensiblement cylindrique et d'un diamètre au plus égal à celui de la gaine 2 dans laquelle il est normalement situé. Il est maintenu en position dans la gaine 2 grâce à la partie inférieure tronconique de celle-ci, selon le présent mode de réalisation. Il comporte sur son pourtour au moins deux encoches 7 et 8 dans lesquelles sont disposés les connecteurs électriques 4 et 5 respectivement.The core 3 is also substantially cylindrical and of a diameter at most equal to that of the sheath 2 in which it is normally located. It is held in position in the sheath 2 thanks to the frustoconical lower part of the latter, according to the present embodiment. It has on its periphery at least two notches 7 and 8 in which the electrical connectors 4 and 5 are arranged respectively.

Chaque connecteur électrique 4, 5 qui est réalisé par exemple à partir d'une feuille métallique notamment par découpe et enroulement, est constitué d'une partie verticale 28 comportant à son extrémité supérieure un manchon cylindrique 9 et au moins une virole de sertissage à son extrémité inférieure.Each electrical connector 4, 5 which is produced for example from a metal foil in particular by cutting and winding, consists of a vertical part 28 comprising at its upper end a cylindrical sleeve 9 and at least one crimping ferrule at its lower end.

Le manchon cylindrique 9 est constitué par deux branches 10 et 11 sensiblement hémicylindriques et séparées l'une de l'autre par une fente 12.The cylindrical sleeve 9 consists of two branches 10 and 11 which are substantially semi-cylindrical and separated from each other by a slot 12.

Ce connecteur électrique comporte, selon le présent mode de réalisation, deux viroles 13 et 14, à son extrémité inférieure, disposées l'une au-dessous de l'autre. La virole 13, ou virole inférieure, est sertie autour de la partie isolante 15 d'un fil conducteur 16 et la virole 14, ou virole supérieure, est sertie autour de la partie conductrice.17 de ce même fil conducteur 16. Chaque connecteur électrique comporte également deux éléments de blocage 18 et 19 symétriquement opposés.This electrical connector comprises, according to the present embodiment, two ferrules 13 and 14, at its lower end, arranged one below the other. The ferrule 13, or lower ferrule, is crimped around the insulating part 15 of a conductive wire 16 and the ferrule 14, or upper ferrule, is crimped around the conductive part. 17 of this same conductive wire 16. Each electrical connector also comprises two locking elements 18 and 19 symmetrically opposite.

Ainsi qu'il a été dit plus haut, le noyau 3 comporte au moins deux encoches 7 et 8 dans lesquelles sont disposés les connecteurs électriques : ces encoches épousent donc plus ou moins la forme de ces connecteurs.As has been said above, the core 3 comprises at least two notches 7 and 8 in which the electrical connectors are arranged: these notches therefore more or less conform to the shape of these connectors.

Chaque encoche est constituée d'une découpe supérieure 20 dans laquelle vient se situer le manchon 9, laquelle est sensiblement plus haute:et plus large aue lui et qui est ouverte à sa partie supérieure, d'une découpe inférieure 21 dans laquelle vient se situer la partie inférieure du connecteur comportant les deux viroles 13 et 14, et une découpe intermédiaire 22 pour le logement des éléments de blocage 18 et 19.Each notch consists of an upper cutout 20 in which the sleeve 9 is located, which is substantially higher : and wider than it and which is open at its upper part, a lower cutout 21 in which is located the lower part of the connector comprising the two ferrules 13 and 14, and a cutout intermediate 22 for housing the locking elements 18 and 19.

Pour réaliser une douille selon la présente invention, il faut sertir les câbles électriques sur chaque connecteur électrique qrâce à leurs viroles 13 et 14, les enfiler dans la gaine extérieure 2, placer chaque connecteur en position dans son encoche respective prévue dans le noyau 3, enfoncer l'ensemble dans la gaine 2 jusqu'à obtenir un blocage de cet ensemble, et enfin introduire le porte-lampe 6 muni de sa lampe 30.To produce a socket according to the present invention, the electrical cables must be crimped onto each electrical connector q thanks to their ferrules 13 and 14, thread them into the outer sheath 2, place each connector in position in its respective notch provided in the core 3, press the assembly into the sheath 2 until this assembly is blocked, and finally introduce the lamp holder 6 fitted with its lamp 30.

Il peut être prévu des moyens pour bloquer le noyau 3 dans la gaine 2, comme notamment représenté sur la figure 4. Selon cet exemple de réalisation, un bossage 23 est situé vers l'extrémité inférieure de la gaine 2, coopérant avec une rainure 24 située à la partie inférieure du noyau 3.Means may be provided for locking the core 3 in the sheath 2, as shown in particular in FIG. 4. According to this embodiment, a boss 23 is located towards the lower end of the sheath 2, cooperating with a groove 24 located at the bottom of the core 3.

Ainsi qu'on aura pu le noter, la présente invention offre en particulier l'avantage de permettre le préser- tissage sur machine automatique des connecteurs électriques sur les câbles. Comme autre avantage, on doit également signaler que l'étanchéité au passage des câbles dans la gaine est assurée de façon très satisfaisante par le fait même que ceux-ci sont serrés dans les encoches prévues dans le noyau pour immobiliser les pièces au cours du montage et comprimer en fin de montage. Les effets de traction sur le câble sont donc repris à la fois par le connecteur et par le montage : il s'en suit une forte amélioration de la résistance à la traction qui s'exerce dans le sens du blocage du noyau dans la gaine extérieure.As will have been noted, the present invention offers in particular the advantage of allowing the pre-pre-weaving on an automatic machine of the electrical connectors on the cables. As another advantage, it should also be noted that the tightness of the passage of the cables in the sheath is very satisfactorily ensured by the very fact that they are clamped in the notches provided in the core to immobilize the parts during assembly. and compress at the end of assembly. The tensile effects on the cable are therefore taken up both by the connector and by the assembly: there follows a strong improvement in the tensile strength which is exerted in the direction of blocking of the core in the outer sheath .

Par ailleurs, il y a lieu de faire remarquer que la liaison électrique qui s'établit entre un connecteur électrique 4 et la broche correspondante 25 du porte-lampe 6, est indépendante des parties constituant la douille 1 : en effet le manchon 4 peut se déformer de façon élastique et librement. Quant aux éléments de blocage 18 et 19 situés dans la découpe 22, ils confèrent une meilleure résistance à l'arrachement.Furthermore, it should be noted that the electrical connection which is established between an electrical connector 4 and the corresponding pin 25 of the lamp holder 6, is independent of the parts constituting the socket 1: in fact the sleeve 4 can be deform elastically and freely. As for the locking elements 18 and 19 located in the cutout 22, they provide better resistance to tearing.

De telles douilles 1, munies de lampes 30, sont notamment utilisées pour constituer des guirlandes électriques. Comme de telles guirlandes peuvent comprendre des lampes ordinaires et/ou clignotantes, il y a lieu de munir ces douilles de détrompeurs.Such sockets 1, fitted with lamps 30, are used in particular to constitute electric garlands. As such garlands can include ordinary and / or flashing lamps, these sockets should be fitted with polarizing pins.

Pour ce faire, on réalise, par exemple sur chaque gaine extérieure 2 une échancrure latérale 26 dans laquelle s'engage un ergot 27 de même forme dont est pourvue le porte-lampe clignotant. Par contre dans le cas de douille pour porte-lampe non-clignotant, il est prévu deux échancrures latérales qui coopèrent avec les deux ergots dont est pourvu le porte-lampe non-clignotant : ainsi un porte-lampe non-clignotant ne peut s'adapter que dans une douille prévue pour lui. Bien évidemment les deux échancrures de la douille sont de préférence situées symétriquement, tout comme d'ailleurs les deux ergots du porte-lampe non-clignotant.To do this, there is produced, for example on each outer sheath 2 a lateral notch 26 in which engages a lug 27 of the same shape which is provided with the flashing lamp holder. On the other hand, in the case of a socket for a non-flashing lamp holder, two lateral notches are provided which cooperate with the two lugs which are provided with the non-flashing lamp holder: thus a non-flashing lamp holder cannot be fit only in a socket provided for him. Obviously the two indentations of the socket are preferably located symmetrically, just like the two pins of the non-flashing lamp holder.

Par ailleurs, comme cela est représenté sur les figures, le noyau 3 est d'une longueur telle qu'une fois bloqué dans la gaine extérieure 2, son sommet affleure l'extrémité supérieure de cette gaine et son extrémité inférieure dépasse de celle de la gaine 2. Ceci est particulièrement avantageux dans la mesure où cette extrémité inférieure peut comporter un trou 29 par lequel on peut faire passer un anneau (non représenté) : ceci permet de suspendre la douille 1 munie de sa lampe 30 sans introduire de contrainte mécanique dans la gaine des fils conducteurs 16.Furthermore, as shown in the figures, the core 3 is of a length such that once locked in the outer sheath 2, its apex is flush with the upper end of this sheath and its lower end protrudes from that of the sheath 2. This is particularly advantageous insofar as this lower end may include a hole 29 through which a ring (not shown) can be passed: this makes it possible to suspend the socket 1 provided with its lamp 30 without introducing mechanical stress into the sheath of the conducting wires 16.

Une structure de douille selon la présente invention permet donc d'obtenir une très bonne liaison élastique entre chaque connecteur électrique et la broche métallique correspondante ou le fil conducteur correspondant disposé sur une broche isolante comme en comporte un porte-lampe pour une telle douille. Dans ce dernier cas, ce fil 25 est avantageusement disposé à l'opposé de la fente 12 du manchon cylindrique 9 grâce à une encoche spécifique ménagée dans la broche isolante.A socket structure according to the present invention therefore makes it possible to obtain a very good elastic connection between each electrical connector and the corresponding metal pin or the corresponding conductive wire disposed on an insulating pin as there is a lamp holder for such a socket. In the latter case, this wire 25 is advantageously disposed opposite the slot 12 of the cylindrical sleeve 9 thanks to a specific notch formed in the insulating pin.

Un autre mode de réalisation de la présente invention qui est représenté sur la figure 8, satisfait également à cette norme. Une telle douille comprend une gaine extérieure 102, dans laquelle est situé un noyau 103 ainsi qu'au moins deux connecteurs électriques 104 et 105,, et un oorte-lamoe L06.Another embodiment of the present invention which is shown in Figure 8, also satisfies to this standard. Such a socket comprises an outer sheath 102, in which is located a core 103 as well as at least two electrical connectors 104 and 105 ,, and an oorte-lamoe L06.

Cette gaine extérieure 102 est sensiblement cylindrique et ouverte à ses deux extrémités. Sa partie inférieure peut être tronconique.This outer sheath 102 is substantially cylindrical and open at its two ends. Its lower part can be frustoconical.

Le noyau 103 est également sensiblement cylindrique et d'un diamètre au plus égal au diamètre intérieur de la gaine 102 dans laquelle il est situé. Il est maintenu en position dans cette gaine grâce à la partie inférieure tronconique de celle-ci. Il comporte, dans ce mode de réalisation, deux ergots verticaux, 140 et 141, disposés symétriquement à sa partie supérieure, lesquels coopérent avec deux encoches disposées symétriquement à la partie supérieure de la gaine 102.The core 103 is also substantially cylindrical and of a diameter at most equal to the inside diameter of the sheath 102 in which it is located. It is held in position in this sheath thanks to the frustoconical lower part thereof. It comprises, in this embodiment, two vertical pins, 1 4 0 and 141, arranged symmetrically at its upper part, which cooperate with two notches arranged symmetrically at the upper part of the sheath 102.

Le noyau 103 comporte sur son pourtour au moins deux encoches 107 et 108 dans lesquelles sont disposés les connecteurs électriques 104 et 105, respectivement.The core 103 has on its periphery at least two notches 107 and 108 in which the electrical connectors 104 and 105 are arranged, respectively.

Chaque connecteur électrique 104, 105 qui est réalisé par exemple à partir d'une feuille métallique notamment par découpe et enroulement, est constitué d'une partie verticale 128 comportant à son extrémité supérieure un manchon cylindrique 109 et au moins une virole de sertissage à son extrémité inférieure.Each electrical connector 104, 105 which is produced for example from a metal sheet in particular by cutting and winding, consists of a vertical part 128 comprising at its upper end a cylindrical sleeve 109 and at least one crimping ferrule at its lower end.

Le manchon cylindrique 109 est constitué par deux branches 110 et 111 sensiblement hémicylindriques et séparées l'une de l'autre par une fente 112.The cylindrical sleeve 109 consists of two branches 110 and 111 which are substantially semi-cylindrical and separated from each other by a slot 112.

Ce connecteur électrique comporte, selon le présent mode de réalisation, deux viroles 113 et 114, à son extrémité inférieure, disposées l'une au-dessous de l'autre. La virole 113, ou virole inférieure, est sertie autour de la partie isolante 115 d'un fil conducteur 116 et la virole 114, ou virole supérieure, est sertie autour de la partie conductrice 117 de ce même fil conducteur 116. Chaque connecteur électrique comporte également deux éléments de blocage 118 et 119 symétriquement opposés.This electrical connector comprises, according to the present embodiment, two ferrules 113 and 114, at its lower end, arranged one below the other. The ferrule 113, or lower ferrule, is crimped around the insulating part 115 of a conductive wire 116 and the ferrule 114, or upper ferrule, is crimped around the conductive part 117 of this same conductive wire 116. Each electrical connector comprises also two locking elements 118 and 119 symmetrically opposite.

Ainsi qu'il a été dit plus haut, le noyau 103 comporte au moins deux encoches 107 et 108 dans lesquelles sont disposés les connecteurs électriques : ces encoches épousent donc plus ou moins la forme de ces connecteurs.As has been said above, the core 103 comprises at least two notches 107 and 108 in which the electrical connectors are arranged: these notches therefore more or less conform to the shape of these connectors.

Chaque encoche est constituée d'une découpe supérieure 120 dans laquelle vient se situer le manchon 109, comme indiqué par les flèches F1 et F2, laquelle est sensiblement plus haute et plus large que lui et qui est ouverte à sa partie supérieure, d'une découpe inférieure 121 dans laquelle vient se situer la partie inférieure du connecteur comportant les deux viroles 113 et 114, et une découpe intermédiaire 122 pour le logement des éléments de blocage 118 et 119.Each notch consists of an upper cutout 120 in which the sleeve 109 is located, as indicated by the arrows F 1 and F 2 , which is substantially higher and wider than it and which is open at its upper part, d 'A lower cutout 121 in which the lower part of the connector including the two ferrules 113 and 114 is located, and an intermediate cutout 122 for housing the locking elements 118 and 119.

Pour réaliser une douille selon la présente invention, il faut sertir les câbles électriques sur chaque connecteur électrique grâce à leurs viroles 113 et 114, les enfiler dans la gaine extérieure 102 placer chaque connecteur en position dans son encoche respective prévue dans le noyau 103, enfoncer l'ensemble dans la qaine 102, selon le sens de la flèche F3, jusqu'à obtenir un blocage de l'ensemble, et enfin introduire le porte-lampe 106 muni de sa lampe 130.To make a socket according to the present invention, it is necessary to crimp the electrical cables on each electrical connector using their ferrules 113 and 114, thread them into the outer sheath 102 place each connector in position in its respective notch provided in the core 103, push in the assembly in the shaft 102, in the direction of the arrow F 3 , until the assembly is blocked, and finally introduce the lamp holder 106 provided with its lamp 130.

Selon cet exemple de réalisation, les moyens pour bloquer le noyau 103 dans la gaine 102 sont constitués par deux ergots 142 situés à la base du noyau 103 : lorsque ce dernier est enfoncé dans la gaine 102, ces ergots 142 en coopérant avec le bord inférieur de cette gaine interdisent toute remontée du noyau 102. Par ailleurs, les ergots supé- rieurs 140 et 141 en coopérant avec leurs encoches respectives interdisent tout enfoncement supplémentaire du noyau 103.According to this exemplary embodiment, the means for locking the core 103 in the sheath 102 are constituted by two lugs 142 located at the base of the core 103: when the latter is pressed into the sheath 102, these lugs 142 by cooperating with the lower edge this duct prohibit kernel lift 102. in addition, the lugs su p E- laughing 140 and 141 cooperating with their respective slots prohibit any further insertion of the core 103.

Ainsi qu'on aura pu le comprendre, le noyau 103 est d'une longueur telle qu'une fois bloqué dans la gaine extérieure 102, son sommet affleure l'extrémité supérieure de cette gaine et son extrémité inférieure dépasse de celle de la gaine 102. Ceci est particulièrement avantageux dans la mesure où cette extrémité inférieure peut comporter un oeilleton 129 par lequel on peut faire passer un anneau (non représenté) : ceci permet de suspendre la douille munie de sa lampe 130 sans introduire de contrainte mécanique dans la gaine des fils conducteurs 116.As will have been understood, the core 103 is of a length such that once blocked in the outer sheath 102, its apex is flush with the upper end of this sheath and its lower end projects beyond that of the sheath 102 This is particularly advantageous insofar as this lower end may include an eyelet 129 through which a ring (not shown) can be passed: this makes it possible to suspend the socket provided with its lamp 130 without introducing mechanical stress into the sheath of the conducting wires 116.

Le noyau 103 à son extrémité supérieure et dans le même plan que les ergots 140, 141, comprend une toile 145 d'isolation électrique qui a pour rôle principal d'auqmenter la distance dans l'air et la ligne de fuite entre les deux connecteurs 104, 105. Cette toile constitue en outre une butée contre tout contact accidentel en fond de douille et empêche la rotation du porte-lampe 106 par l'intermédiaire de l'embrèvement 146 qui coopère avec elle, et ce pour éviter d'introduire des contraintes transversales dans les connecteurs et le porte-lampe en cas de mauvaise manipulation.The core 103 at its upper end and in the same plane as the lugs 140, 141, comprises a cloth 145 of electrical insulation which has the main role of increasing the distance in the air and the line of flight between the two connectors 104, 105. This fabric also constitutes a stop against any accidental contact at the bottom of the socket and prevents rotation of the lamp holder 106 by means of the recess 146 which cooperates with it, in order to avoid introducing transverse stresses in the connectors and the lamp holder in the event of improper handling.

Il y a lieu de faire remarquer que la liaison qui s'établit entre un connecteur électrique 104 et la broche correspondante 125 du porte-lampe 106 est indépendante des parties constituant la douille, tout comme dans l'exemple de réalisation précédent.It should be noted that the connection which is established between an electrical connector 104 and the corresponding pin 125 of the lamp holder 106 is independent of the parts constituting the socket, as in the previous embodiment.

Des guirlandes électriques constituées de telles douilles peuvent comporter des lampes 130 ordinaires et/ou clignotantes, il y a lieu de munir ces douilles de détrompeurs.Electric strings made up of such sockets may include ordinary and / or flashing lamps 130, these sockets should be fitted with polarizing devices.

Pour ce faire, on réalise, par exemple sur chaque gaine extérieure 102, une échancrure latérale 126 dans laquelle s'engage un ergot 127 de même forme dont est pourvue le porte-lampe cliqnotant. Par contre dans le cas de douille pour re porte-lampe non-cliqnotant,il est prévu deux échancrures latérales qui coopèrent avec les deux ergots dont est pourvu le- porte-lampe non-clignotant : ainsi un porte-lampe non cliqnotant ne peut s'adapter que dans une douille prévue pour lui,. Bien évidemment les deux échancrures de la douille sont de préférence situées symétriquement, tout comme d'ailleurs les deux ergots du porte-lampe non-cliqnotant.To do this, there is provided, for example on each outer sheath 102, a lateral notch 126 in which engages a lug 127 of the same shape which is provided with the flickering lamp holder. On the other hand, in the case of a socket for a non-flashing lamp holder, two side notches are provided which cooperate with the two lugs which are provided with the non-flashing lamp holder: thus a non-clicking lamp holder cannot be 'fit only in a socket provided for him. Obviously the two indentations of the socket are of reference p located symmetrically, just like the two lugs of the non-clicking lamp holder.
