Description

La présente invention se rapporte à un connecteur de dérivation.The present invention relates to a branch connector.

L'invention vise un connecteur destiné à être utilisé pour être monté sur des conducteurs constitués d'une nappe de matière isolante souple dans laquelle sont noyés parallèlement des conducteurs électriques et constituant des lignes de distribution, ledit connecteur permettant de brancher directement des conducteurs de dérivation sur ces lignes, lesdits conducteurs, étant, de préférence du même type en nappe. L'invention trouve une application particulièrement intéressante pour les systèmes dits "multiplex".The invention relates to a connector intended to be used to be mounted on conductors consisting of a sheet of flexible insulating material in which electrical conductors are embedded in parallel and constituting distribution lines, said connector allowing direct connection of branch conductors. on these lines, said conductors being preferably of the same type in ply. The invention finds a particularly interesting application for so-called "multiplex" systems.

Le connecteur, selon l'invention est caractérisé en ce qu'il comprend deux demi-coquilles pourvues de moyens conjugués pour leur assemblage en insérant entre elles un élément intermédiaire, ledit élément intermédiaire comportant une série d'organes de liaisons électriques à déplacement d'isolant constitués, chacun par une bande métallique bonne conductrice de l'électricité et découpée pour affecter la forme d'un H avec une barre transversale et deux branches qui ménagent entre elles, des entailles à ouverture évasée, chaque organe de liaison électrique faisant, par une extrémité, saillie à la surface d'une face de l'élément intermédiaire, et par son autre extrémité à la surface de l'autre face dudit élément intermédiaire, chaque demi-coquille comportant sur sa face destinée à coïncider avec l'élément intermédiaire des fentes destinées à recevoir les extrémités libres des organes de liaison électrique.The connector according to the invention is characterized in that it comprises two half-shells provided with conjugate means for their assembly by inserting between them an intermediate element, said intermediate element comprising a series of electrical connection members with displacement of insulator made up, each by a metal band good conductor of electricity and cut to affect the shape of an H with a transverse bar and two branches which form between them, notches with flared opening, each member of electrical connection making, by one end, projecting from the surface of one face of the intermediate element, and by its other end from the surface of the other face of said intermediate element, each half-shell comprising on its face intended to coincide with the intermediate element slots intended to receive the free ends of the electrical connection members.

Grâce à une telle structure on monte le connecteur de manière que la nappe de distribution soit insérée entre l'une des demi-coquilles et une face de l'élément intermédiaire, tandis que la nappe de dérivation est insérée entre l'autre demi-coquilles et l'autre face de l'élément intermédiaire, le simple assemblage des demi-coquilles entre elles assurant la liaison électrique par découpage des isolants par les biseaux des ailes des organes de liaison électrique et engagement des conducteurs ainsi dénudés dans les entailles desdits organes.Thanks to such a structure, the connector is mounted so that the distribution ply is inserted between one of the half-shells and one face of the intermediate element, while the bypass ply is inserted between the other half-shells. and the other face of the intermediate element, the simple assembly of the half-shells together ensuring the electrical connection by cutting the insulators by the bevels of the wings of the connecting members electric and engagement of the conductors thus stripped in the notches of said organs.

De préférence les extrémités libres des branches des organes de liaison électrique sont taillées en biseau et coupantes.Preferably, the free ends of the branches of the electrical connection members are bevelled and cutting.

Suivant un détail constructif, chaque demi-coquille comporte sur sa face tournée en regard de la face correspondante de l'élément intermédiaire des creusages correspondant aux conducteurs, les faces dudit élément intermédiaire étant pourvues de creusages correspondants.According to a constructive detail, each half-shell has, on its face turned opposite the corresponding face of the intermediate element, hollows corresponding to the conductors, the faces of said intermediate element being provided with corresponding hollows.

Suivant une caractéristique constructive, l'élément intermédiaire est percé d'une série de conduits destinés à recevoir, chacun, un organe de liaison électrique, lesdits organes de liaison électrique présentant sur au moins une face, des saillies, lesdits organes de liaison électrique étant engagés à force dans les conduits et, les saillies assurant la fixation desdits organes dans lesdits conduits. On réalise, ainsi, un moyen très simple de montage des organes de liaison électique.According to a constructive characteristic, the intermediate element is pierced with a series of conduits intended to each receive an electrical connection member, said electrical connection members having on at least one face, projections, said electrical connection members being forcibly engaged in the conduits and, the projections ensuring the fixing of said members in said conduits. This provides a very simple means of mounting the electrical connection members.

De préférence, les conduits sont disposés par paires, soit une paire pour chaque conducteur et sont décalés pour être disposés en quinconce, les fentes des faces correspondantes des demi-coquilles étant disposées de la même manière. Ainsi, on réalise pour chaque conducteur deux liaisons, de sorte qu'on est assuré d'une bonne connexion électrique. Comme les organes de liaison électrique sont disposés en quinconce, les dimensions du connecteur sont réduites.Preferably, the conduits are arranged in pairs, ie one pair for each conductor and are offset to be staggered, the slots of the corresponding faces of the half-shells being arranged in the same way. Thus, two connections are made for each conductor, so that a good electrical connection is ensured. As the electrical connection members are staggered, the dimensions of the connector are reduced.

Enfin, suivant une dernière caractéristique, chaque demi-coquille comporte au voisinage d'un bord une première mortaise et au voisinage d'un bord opposé une seconde mortaise, celles-ci étant décalées et ayant des sections différentes, tandis que l'élément intermédiaire comporte des tenons correspondants. Ainsi, l'élément intermédiaire ne peut être monté entre les demi-coquilles que dans une seule position ce qui évite toute erreur lors de la mise en place du connecteur.Finally, according to a last characteristic, each half-shell comprises in the vicinity of an edge a first mortise and in the vicinity of an opposite edge a second mortise, these being offset and having different sections, while the intermediate element has corresponding studs. Thus, the intermediate element can only be mounted between the half-shells in one position, which avoids any error during the positioning of the connector.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier et donné à titre d'exemple seulement et représenté aux dessins annexés, dans lequels :The invention will now be described in more detail with reference to a particular embodiment and given by way of example only and shown in the accompanying drawings, in which:

L'élément intermédiaire 3 comprend un corps central 80 qui comporte sur chaque face deux tenons 81 et 82, ceux-ci étant décalés et les tenons 82 ayant une section supérieure à celles des tenons 81.The intermediate element 3 comprises a central body 80 which has on each face two tenons 81 and 82, these being offset and the tenons 82 having a cross section greater than those of the tenons 81.

Le corps central 80 est percé de paires de conduits 84, 85, 86 et 87 disposés de la même manière que les fentes 51, 54, 56 et 58 et que les fentes 71 à 74 afin que, lorsque les trois éléments sont montés, les fentes soient alignées avec les conduits correspondants.The central body 80 is pierced with pairs of conduits 84, 85, 86 and 87 arranged in the same way as the slots 51, 54, 56 and 58 and that the slots 71 to 74 so that, when the three elements are mounted, the slots are aligned with the corresponding conduits.

Le corps 80 est relié par des barreaux 89 à une barrette d'extrémité 90 comportant sur une face des crans 91, 92, 93 et 94 et sur l'autre face des crans correspondants 95, 96, 97 et 98.The body 80 is connected by bars 89 to an end bar 90 having on one face notches 91, 92, 93 and 94 and on the other face of corresponding notches 95, 96, 97 and 98.

Du côté opposé à la barrette d'extrémité 90, l'élément intermédiaire 3 comporte des barreaux 100 supportant une barrette d'extrémité 101 comportant sur une face des crans 91, 92, 93 et 94 et sur l'autre face des crans 95 à 98.On the side opposite to the end bar 90, the intermediate element 3 comprises bars 100 supporting an end bar 101 having on one side notches 91, 92, 93 and 94 and on the other face notches 95 to 98.

Chaque conduit 84 à 87 reçoit un organe de liaison électrique à déplacement d'isolant. Ces organes référencés 105 et 106 sont de deux dimensions. Les organes 105 destinés à être engagés dans les conduits 85 et 86 sont découpés dans une bande métallique et affectent la forme générale d'un H avec deux branches 107 et 108 et une barre transversale 109 (voir figure 4). Ainsi, il est formé deux entailles 110 et 111. Les extrémités libres des branches 107 et 108 sont taillées en biseau afin de former une ouverture évasée des entailles, les biseaux étant tranchants. Sur l'une des faces de l'organe 105, il est formé quatre emboutis qui forment sur l'autre face des saillies 112. Un organe 105 est engagé à force dans chacun des conduits 84 et 85, les saillies 112 assurant, en coopérant avec les conduits la fixation.Each conduit 84 to 87 receives an electrical connection member with insulation displacement. These bodies referenced 105 and 106 are of two dimensions. The members 105 intended to be engaged in the conduits 85 and 86 are cut from a metal strip and have the general shape of an H with two branches 107 and 108 and a transverse bar 109 (see FIG. 4). Thus, two notches 110 and 111. are formed. The free ends of the branches 107 and 108 are cut in a bevel in order to form a flared opening of the notches, the bevels being sharp. On one of the faces of the member 105, four stampings are formed which form on the other face of the projections 112. A member 105 is forcibly engaged in each of the conduits 84 and 85, the projections 112 ensuring, by cooperating with conduits fixing.

Les organes 106 sont réalisés de la même façon que les organes 105, on a donc reporté pour cet organe 106 les références utilisées pour la description de l'organe 105 affectées de la lettre "a" (voir figure 5).The members 106 are produced in the same way as the members 105, so the references used for the description of the member 105 assigned the letter "a" have been reported for this member 106 (see FIG. 5).

Les organes 106 étant destinés à recevoir des conducteurs ayant une section plus importante que ceux destinés à coopérer avec les organes 105, les fentes 110a et 111a sont plus larges.The bodies 106 are intended to receive conductors having a larger section than those intended to cooperate with the bodies 105, the slots 110 and 111 are wider.

Les conduits 86 et 87 sont garnis chacun avec un organe 106 engagé à force de manière que les saillies 112a assurent la fixation dans lesdits conduits.The conduits 86 and 87 each are filled with a body 106 engaged by force so that the projections 112 serve to fix in said ducts.

Le relief 50 comporte une mortaise 120 destinée à recevoir un tenon 81, et une mortaise 121 destinée à recevoir un tenon 82, le relief 70 étant percé de deux mortaises 122 et 123 afin de recevoir les tenons 81 et 82 de l'autre face du corps 80.The relief 50 comprises a mortise 120 intended to receive a tenon 81, and a mortise 121 intended to receive a tenon 82, the relief 70 being pierced with two mortises 122 and 123 in order to receive the tenons 81 and 82 on the other side of the body 80.

Compte tenu que les tenons 81 et 82 sont décalés et ont des sections différentes, le corps 80 ne peut se monter que dans un seul sens entre les demi-coquilles 1 et 2.Given that the pins 81 and 82 are offset and have different sections, the body 80 can only be mounted in one direction between the half-shells 1 and 2.

Comme on le voit aux figures, les barrettes d'extrémité 90 et 101 viennent coïncider avec les encoches 16 et 59 des demi-coquilles 1 et 2 afin que les crans 95, 96, 97 et 98 coïncident avec les crans 10, 11, 12 et 13, tandis que les crans 91, 92, 93 et 94 coïncident avec les crans correspondants 62, 63, 64 et 65.As can be seen in the figures, the end bars 90 and 101 coincide with the notches 16 and 59 of the half-shells 1 and 2 so that the notches 95, 96, 97 and 98 coincide with the notches 10, 11, 12 and 13, while the notches 91, 92, 93 and 94 coincide with the corresponding notches 62, 63, 64 and 65.

Le connecteur de dérivation peut être monté directement sur la nappe 20 qui comporte les conducteurs d'amenée du courant et permet, directement sur chacun des quatre conducteurs 21 à 24 de cette nappe, de brancher un conducteur de dérivation correspondant.The bypass connector can be mounted directly on the sheet 20 which includes the current supply conductors and allows, directly on each of the four conductors 21 to 24 of this sheet, to connect a corresponding bypass conductor.
