Description
L'invention concerne une pièce d'interconnexion pour bloc de raccordement électrique à prise de test, notamment pour bloc de jonction ou connecteur, et les blocs équipés d'au moins une telle pièce d'interconnexion.The invention relates to an interconnection piece for a connection block. test socket, especially for terminal block or connector, and blocks fitted with at least one such interconnection piece.
De nombreux blocs de raccordement, monoblocs ou modulaires, notamment de type bloc de jonction ou de type connecteur mâle ou femelle, comportent une ou plusieurs pièces d'interconnexion électrique destinées à coopérer chacune, d'une part, avec une pièce complémentaire d'un autre équipement électrique, tel que par exemple d'un connecteur complémentaire, et, d'autre part, directement ou indirectement à un conducteur électrique de desserte d'équipement, par exemple un fil.Many connection blocks, monobloc or modular, in particular of terminal block type or male or female connector type, have one or more several electrical interconnection pieces each intended to cooperate, of a share, with a complementary piece of other electrical equipment, such as by example of a complementary connector, and, on the other hand, directly or indirectly to an electrical conductor serving equipment, for example a wire.
Pour des raisons de sécurité, les pièces d'interconnexion de tels blocs sont généralement enfermées, en particulier lorsqu'elles sont mises sous tension de manière à éliminer au maximum les risques de liaison électrique non prévue avec un utilisateur ou avec une partie métallique extérieure et étrangère.For security reasons, the interconnection pieces of such blocks are generally enclosed, especially when energized from so as to eliminate as much as possible the risks of electrical connection not provided for with a user or with an external and foreign metal part.
Toutefois, il est parfois nécessaire de pouvoir venir vérifier qu'une pièce d'interconnexion électrique enfermée dans un logement est bien sous tension, et il est connu de prévoir un agencement dit de test au niveau du boítier pour permettre d'entrer électriquement en contact avec la pièce, classiquement par l'intermédiaire d'une fiche extérieure et indépendante venant s'introduire dans le boítier au travers d'un orifice spécifiquement prévu à cet effet.However, it is sometimes necessary to be able to come and check that a room of electrical interconnection locked in a housing is well under tension, and it is known to provide a so-called test arrangement at the housing for allow electrical contact with the part, conventionally by through an external and independent plug coming into the housing through an orifice specifically provided for this purpose.
Les fiches de test sont généralement d'allure cylindrique et il en existe des modèles courants qui n'ont pas exactement même diamètre tout en étant dans une même gamme de diamètres correspondant à un type d'utilisation donné. L'utilisation de fiches d'un diamètre supérieur à celui de l'orifice prévu pour elles sur un boítier donné n'est bien entendu pas possible et l'utilisation de fiches d'un diamètre inférieur à celui prévu ne s'effectue pas dans de bonnes conditions dans la mesure où une fiche de diamètre inférieur au diamètre prévu est souvent mal maintenue dans un agencement prévu pour une fiche plus grosse.Test sheets are generally cylindrical and there are some common models that do not have exactly the same diameter while being in a same range of diameters corresponding to a given type of use. The use of plugs with a diameter larger than that of the hole provided for them on a given box is of course not possible and the use of plugs from a diameter smaller than that planned is not carried out under good conditions in since a plug with a diameter smaller than the expected diameter is often wrong maintained in an arrangement provided for a larger plug.
L'invention propose donc un bloc de raccordement électrique comportant au moins un boítier doté d'une prise de test permettant la pénétration d'une fiche conductrice externe dans le boítier par l'intermédiaire d'un conduit guide d'insertion pour une mise en liaison électrique par contact avec une pièce d'interconnexion, conductrice, immobilisée dans le boítier.The invention therefore provides an electrical connection block comprising at minus a box with a test socket allowing the penetration of a plug external conductor in the housing via a guide duct insert for electrical connection by contact with a part interconnection, conductive, immobilized in the housing.
Selon une caractéristique de l'invention, la pièce d'interconnexion conductrice comporte une languette ayant une extrémité élastiquement positionnée sur la trajectoire d'une fiche introduite dans le conduit guide pour connexion avec la pièce d'interconnexion, cette extrémité étant en saillie par rapport à ce conduit, en l'absence de fiche de manière à être latéralement repoussée lorsqu'une fiche est mise en place au travers du conduit.According to a characteristic of the invention, the conductive interconnection piece has a tongue having one end resiliently positioned on the trajectory of a plug inserted in the guide duct for connection with the interconnection piece, this end projecting from this conduit, in the absence of a plug so as to be laterally pushed back when a plug is placement through the conduit.

prévu pour elle dans le boítier, de l'autre côté de la partie plane 15 par rapport
aux parois 18 bordant le conduit.In the proposed embodiment, the connecting
Le boítier comporte un conduit guide d'insertion 20 prévu pour permettre
l'introduction d'un fil 12 au travers du chas et du conduit de passage de la pièce
d'interconnexion 4 Il comporte aussi un conduit de manoeuvre 21 permettant
l'enfoncement d'un moyen de pression, par exemple de type tige de poussée ou
poussoir, pour venir partiellement écraser la boucle de la pièce de connexion 6
depuis la position où cette boucle est peu ou pas du tout écrasée et où le chas est
au moins partiellement obstrué, jusqu'à la position où la boucle est écrasée
suffisamment pour que le chas laisse dégagée l'entrée du conduit de passage de fil
de la pièce d'interconnexion 4 Un fil 12 peut alors être engagé dans le conduit de
passage au travers du chas et contre la partie plane 15, le relâchement du moyen
de pression en libérant la boucle entraíne alors le coincement du fil 12 contre cette
partie plane 15 par un bord du chasThe housing includes an
L'extrémité du conduit de passage pour fil extérieur de la pièce d'interconnexion 4
est obturée par une portion de languette 22 portée par la partie plane 15 à
l'opposé du prolongement 16 Cette portion de languette 22 est repliée plus ou
moins perpendiculairement par rapport à la partie plane 15 de manière à venir se
positionner entre les bras 14, elle est prolongée par une portion d'extrémité de
languette 23 selon une structure en U, cette extrémité venant se positionner sur la
trajectoire suivie par une fiche dans le boítier au travers d'un conduit d'insertion
25 pour connexionThe end of the passage conduit for external wire of the interconnection piece 4
is closed by a
L'extrémité de languette 23 est éventuellement en saillie en bordure du conduit à
travers d'une paroi duquel elle pénètre, dans la réalisation présentée, elle est
positionnée d'une manière différente en aval de ce conduit et partiellement devant
son embouchure à l'intérieur du boítier, lorsque la pièce d'interconnexion 4 qui la
comporte est en place et que le conduit 25 est inutilisé Ce conduit 25 possède un
diamètre intérieur qui correspond au diamètre extérieur de la fiche de test la plus
épaisse que le boítier est susceptible d'accepter Lorsqu'une fiche de test
introduite dans le conduit 25 est au diamètre maximal prévu, elle repousse
latéralement l'extrémité de languette 23 par rapport au conduit 25 en appuyant sur
cette extrémité avec lequel elle est alors électriquement en contact. Lorsqu'une
fiche de test introduite a un diamètre inférieur au diamètre maximal prévu tout en
étant supérieur à une valeur minimale déterminée, elle vient appuyer contre
l'extrémité de languette 23 qu'elle repousse et au long de laquelle elle vient se
positionner de manière que cette extrémité la maintienne élastiquement en
position dans le conduit 25 du boítier en prenant appui sur elle. Un contact
électrique est alors simultanément établi entre la pièce d'interconnexion 4 et la
fiche 3 par l'intermédiaire de l'extrémité de languette 23. Il est alors par exemple
possible de vérifier par l'intermédiaire d'une fiche 3 venant en contact avec une
languette 22 à l'extrémité 23 de cette languette que la pièce d'interconnexion 4 est
sous tension lorsqu'elle est alimentée par l'intermédiaire d'un fil externe 12 inséré
dans le chas d'une pièce de connexion 6 montée sur la pièce d'interconnexion 4 et
plaqué par ce chas contre la zone plane 15 de cette pièce et qu'en conséquence est
alimentée une pièce conductrice dotée d'une extrémité conductrice 13 enfichée
entre les bras 14 de fourche de la pièce de connexion 4.The
