Abstract

L'invention concerne un dispositif de fixation amovible d'un connecteur électrique sur un substrat de câblage. Le connecteur est constitué d'un boîtier isolant qui comporte sur des côtés opposés des ouvertures d'insertion de sorte que des broches de contact électrique de conducteurs électriques peuvent être insérés, notamment serrés, sur un premier côté et des extrémités, dépourvues d'isolant, de conducteurs électriques peuvent être insérées, notamment serrées, sur un second côté. En outre, un connecteur multipoints, compatible avec les ouvertures d'insertion sur le premier côté, peut être fixé sur le support de câblage. Le boîtier isolant comporte au moins une saillie, en forme de crochet ou de bec, saillant du boîtier isolant, qui se trouve sur la paroi latérale du boîtier qui est sensiblement parallèle à la direction d'insertion des broches de contact électrique. Sur le support de câblage est fixé un étrier à ressort qui comporte une partie d'encliquetage qui s'engage en arrière de la saillie, saillant du boîtier isolant du connecteur, lorsque le connecteur est placé sur le connecteur multipoints et qui forme une butée empêchant le retrait du connecteur.
