It should be noted that the term "electrical device” is to be understood here in a broad sense, which in particular also includes junction boxes and plug connectors In many cases, the housing of an electrical device consists of two joinable housing parts, which after joining the connecting cable in a designated place between them pinch. However, this type of strain relief works less well when relatively cross-section strong and rigid connection cables are to be attached to a housing. In particular, if a plurality of cables are to be attached to a housing, it is expedient to provide for this purpose particularly suitable fastening means.

Abstract

L'invention concerne un appareil électrique, comprenant un boîtier, lequel présente au moins une tubulure d'entrée de câble formée d'un seul tenant avec ce dernier, à travers laquelle un câble est guidé à l'intérieur du boîtier, et un capuchon de retenue, qui comprend une ouverture de passage à travers laquelle le câble est guidé, et un manchon, qui présente une section de fixation reposant sur la gaine du câble et une surface annulaire s'étendant radialement par rapport au câble. Une fois le capuchon de retenue monté, ce dernier fixe le manchon sur la tubulure d'entrée de câble. Une fois le capuchon de retenue monté, l'ouverture de passage de ce dernier recouvre la section de fixation du manchon et la surface de bord de l'ouverture de passage presse la section de fixation sur la gaine du câble, et le capuchon de retenue et la tubulure d'entrée de câble sont reliés ensemble par une liaison à baïonnette.
