Rear joint for an electrical component

摘要

The coupling (10) has a hinged part with a cylindrical sleeve for passing a cable, and a cylindrical sleeve (30) having an end (30a) for coupling an electrical component. Two pairs of arms (32, 34) are fixed parallel to each other, where free ends of each pair of the arms face each other. Faces of the ends are provided with relative angular positions. The arms having ends disposed between the ends of the other arms are elastically deformable. A cause unit temporarily causes the deformable arms to deform to enable the part to pass from one angular position to another angular position.
