  • the housing 1 can possibly be provided with a longitudinal groove and the socket B, which is installed, for example, as a built-in connector in a device G (see Fig. 20), may be provided with a corresponding mating longitudinal rib to the alignment of the connector assembly with respect to the socket B during insertion of the plug assembly into the socket to ensure.
  • a snap-action pawl or spring latch for releasably connection of the connector assembly to the socket can be provided. This spring latch then preferably engages in a recess 17 on the outside of the housing 1.

Abstract

L'invention concerne un ensemble de connecteurs destiné à être utilisé avec des câbles (K) pour de connecteurs de câble (S), qui comprend un boîtier (1) destiné à recevoir le connecteur de câble (S), une élément de serrage (5) entourant le câble (K), reçu dans le boîtier (1) et serrant à l'état comprimé le câble (K), et un manchon de serrage (3) destiné à former une liaison filetée avec le boîtier (1). Lorsque la liaison filetée est serrée, l'élément de serrage (5) est contraint dans le boîtier (1) et le câble (K) est serré dans l'élément de serrage (5). L'extrémité avant de l'élément de serrage (5), qui fait face au connecteur de câble (S), est conçue pour recevoir et positionner le connecteur de câble (S) dans une position prédéterminée à l'extrémité avant de l'élément de serrage (5) ou est munie d'au moins une butée destinée au connecteur de câble (S). Ainsi, lorsque la liaison filetée est bien serrée, le connecteur de câble (S) est également positionné et fixé sans pouvoir tourner par rapport au boîtier (1) et à l'élément de serrage (5).
