Abstract

The connector comprises a laterally open stirrup (7) which defines two superposed parallel fins (7a,7b) which are perforated near to the centre of the stirrup to receive a bolt (6). The bolt provides the mounting for the stirrup on to one of the connection bars (2). Further bolts are used to support and insulating cover (10) fitting over an electrical protection device which may, for example, be an extractable cartridge fuse (11). A reinforcing spacer (8) is mounted between the two fins of the stirrup (7).

Description

La présente invention a trait aux dispositifs de raccordement électrique généralement connus sous le nom de "grilles" et destinés à permettre le branchement d'une série de dérivations à partir de câbles principaux d'alimentation. The present invention relates to electrical connection devices generally known as "grids" and intended to allow the connection of a series of taps from main power cables.

On sait que les dispositifs de ce type comprennent généralement un support en une matière isolante sur lequel sont fixées, parallèlement les unes aux autres, des barres métalliques en nombre égal à celui des conducteurs du câble principal d'alimentation. Chacune de ces barres est équipée de connecteurs indépendants pour le branchement d'un conducteur du câble principal et des conducteurs des dérivations à réaliser. It is known that devices of this type generally comprise a support made of an insulating material on which are fixed, parallel to one another, metal bars in a number equal to that of the conductors of the main power cable. Each of these bars is equipped with independent connectors for connecting a conductor of the main cable and the conductors of the branches to be made.

La Demande de Brevet français N" 94 01178 déposée le 28 Avril 1994 au nom de la présente Demanderesse a pour objet un dispositif de raccordement du genre en question qui se distingue de la construction classique en ce qu'il est constitué par un nombre variable de modules dont chacun comprend un socle isolant à profil étagé sur lequel sont appliquées les barres surmontées d'un cache de recouvrement, lequel est découpé d'ouvertures permettant l'application, contre lesdites barres, de la base des connecteurs ou autres appareillages. The French Patent Application No. 94 01178 filed on April 28, 1994 in the name of the present Applicant relates to a connection device of the type in question which differs from conventional construction in that it consists of a variable number of modules, each of which comprises an insulating base with a stepped profile on which the bars are applied surmounted by a covering cover, which is cut out of openings allowing the application, against said bars, of the base of the connectors or other devices.

La présente invention se propose de réaliser un système propre à permettre la mise en place de branchements protégés sur de tels dispositifs de raccordement, tout particulièrement sur ceux du type décrit dans la Demande de Brevet sus-mentionnée. The present invention proposes to provide a system capable of allowing the establishment of protected connections on such connection devices, especially on those of the type described in the above-mentioned patent application.

La système suivant l'invention est principalement remarquable en ce qu'il comprend un étrier ouvert latéralement pour définir deux ailes parallèles superposées qui sont perforées au voisinage de la partie médiane pour le passage d'un boulon assurant la fixation dudit étrier contre l'une des barres du dispositif de raccordement, lequel boulon est identique à ceux utilisés pour opérer la solidarisation des connecteurs et autres appareillages sur les barres précitées.L'extrémité libre de chacune de ces ailes est agencée pour supporter le corps isolant d'un appareillage de protection du type à fusible extractible, 1 'une des mâchoires de cet appareillage étant directement prévue à 1 'extrémité libre de 1 'une des ailes, tandis que sur l'autre mâchoire vient se fixer l'un des conducteurs d'un câble de branchement. The system according to the invention is mainly remarkable in that it comprises a bracket open laterally to define two superimposed parallel wings which are perforated in the vicinity of the middle part for the passage of a bolt ensuring the fixing of said bracket against one bars of the connection device, which bolt is identical to those used to secure the connectors and other devices on the aforementioned bars. The free end of each of these wings is designed to support the insulating body of a protective device of the extractable fuse type, one of the jaws of this apparatus being directly provided at the free end of one of the wings, while on the other jaw is fixed one of the conductors of a connection cable .

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une coupe transversale schématique d'un dispositif de raccordement équipé d'un système suivant l'invention. The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a schematic cross section of a connection device equipped with a system according to the invention.

Fig. 2 montre en perspective la conformation de 1 'étrier du système suivant fig. 1. Fig. 2 shows in perspective the conformation of the stirrup of the system according to FIG. 1.

Fig. 3 représente de la même manière la mâchoire opposée. Fig. 3 shows in the same way the opposite jaw.

Le dispositif de raccordement représenté est conforme à la Demande de Brevet citée plus haut. Oh retrouve un socle modulaire 1 à profil étagé formant support isolant pour quatre barres métalliques 2 orientées parallèlement les unes aux autres et réunissant les différents socles modulaires qui constituent le dispositif. Chaque barre 2 est fixée en place à l'aide de vis telles que 3 et porte au moins un connecteur 4 pour son raccordement à l'un des conducteurs du câble principal qui alimente le dispositif. A chaque socle 1 est associé un cache supérieur 5 en matière isolante, établi au même profil étagé que les socLes 1 et pourvu de cloisons parallèles de séparation 5a. The connection device shown complies with the Patent Application cited above. Oh finds a modular base 1 with a stepped profile forming an insulating support for four metal bars 2 oriented parallel to each other and bringing together the different modular bases which constitute the device. Each bar 2 is fixed in place using screws such as 3 and carries at least one connector 4 for its connection to one of the conductors of the main cable which supplies the device. Each base 1 is associated with an upper cover 5 made of insulating material, established with the same stepped profile as the bases 1 and provided with parallel partition walls 5a.

Conformément à la présente invention, dans 1 'une des perforations ménagées de place en place dans deux des barres 2 est engagé un boulon 6 identique à ceux qui assurent la fixation des connecteurs 4 sur les barres 2. Le boulon 6 considéré traverse les ailes superposées 7a et 7b d'un étrier 7 ouvert latéralement. Entre ces ailes 7a et 7b, le boulon 6 reçoit une entretoise tubulaire 8 qui renforce la résistance de 1 'étrier 7 ; on notera que les perforations 7c (fig. 2) pratiquées dans les ailes 7a et 7b pour le passage du boulon 6 sont prévues au voisinage immédiat de la partie médiane dudit étrier, de sorte qu'on obtient une fixation très résistante et que l'aile inférieure 7a est ainsi fermement appliquée contre la face supérieure de la barre 2 correspondante. According to the present invention, in one of the perforations formed from place to place in two of the bars 2 is engaged a bolt 6 identical to those which secure the connectors 4 on the bars 2. The bolt 6 considered passes through the superimposed wings 7a and 7b of a stirrup 7 open laterally. Between these wings 7a and 7b, the bolt 6 receives a tubular spacer 8 which reinforces the resistance of the stirrup 7; it will be noted that the perforations 7c (fig. 2) made in the wings 7a and 7b for the passage of the bolt 6 are provided in the immediate vicinity of the middle part of said stirrup, so that a very resistant fixing is obtained and that the lower wing 7a is thus firmly applied against the upper face of the corresponding bar 2.

L'extrémité de cette aile inférieure 7a comporte un taraudage 7d pour le vissage d'une vis 9 qui assure la fixation de la base du corps isolant 10 d'un appareillage de protection 11, du type à cartouche fusible extractible ; à la façon en soi connue, le corps isolant 10 est obtenu par assemblage de deux parties symétriques. De manière classique, les oreilles latérales de cette cartouche 11 coopèrent avec deux mâchoire res fixes 12 et 13 ; la mâchoire amont 12 est directement prévue à 1 'ex- trémité libre relevée de l'aile supérieure 7b, tandis que la mâchoire aval 13 est supportée par une patte intérieure oblique 10a du corps 10 de l'appareillage 11.Contre l'embase de cette seconde mâchoire 13 vient se fixer l'un des deux conducteurs 14 du câble de branchement. The end of this lower wing 7a includes a thread 7d for screwing a screw 9 which secures the base of the insulating body 10 of protective equipment 11, of the type with extractable fuse cartridge; in known manner, the insulating body 10 is obtained by assembling two symmetrical parts. Conventionally, the lateral ears of this cartridge 11 cooperate with two fixed jaws 12 and 13; the upstream jaw 12 is directly provided at the raised free end of the upper wing 7b, while the downstream jaw 13 is supported by an oblique inner tab 10a of the body 10 of the apparatus 11. Against the base of this second jaw 13 fixes one of the two conductors 14 of the connection cable.

Oh observera que le corps isolant 10 de l'appareillage est soli daire d'une paroi arrière 10b formant écran et évitant tout contact intempestif de l'utilisateur avec l'étrier 7. Oh will observe that the insulating body 10 of the apparatus is secured to a rear wall 10b forming a screen and preventing any untimely contact of the user with the stirrup 7.

Oh conçoit que le système suivant l'invention permet la réalisation simple et rapide de branchements protégés , cette réalisation peut intervenir soit à l'origine, c'est-à-dire lors de la mise en place du dispositif de raccordement, soit à un moment quelconque au cours de l'utilisation de ce dispositif. Le contact électrique entre les barres 2 et les appareillages 11 est excellent et l'on notera que le montage du branchement présente un encombrement remarquablement réduit. Oh conceives that the system according to the invention allows the simple and rapid realization of protected connections, this realization can occur either at the origin, that is to say during the installation of the connection device, or at a any time during the use of this device. The electrical contact between the bars 2 and the apparatuses 11 is excellent and it will be noted that the mounting of the connection has a remarkably reduced bulk.

I1 n'est pas sans intérêt d'observer que le système suivant lin- vention permet, dans le cas d'un comptage par compteur électrique placé chez un particulier, de supprimer le coffret individuel de branchement électrique ordinairement prévu en limite de propriété. Une série d'appareillages de ce type sont susceptibles hêtre regroupés en un même point pour desservir plusieurs habitations d'un même lotissement, en permettant la suppression de la série correspondante des coffrets individuels classiques. It is not without interest to observe that the system according to the invention makes it possible, in the case of metering by electric meter placed at a private individual, to remove the individual electrical connection box usually provided at the property boundary. A series of switchgear of this type may be grouped together at the same point to serve several dwellings in the same subdivision, allowing the elimination of the corresponding series of classic individual boxes.

I1 doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et quelle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  I1 should moreover be understood that the foregoing description has been given only by way of example and which in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
