Abstract: A system for fastening the coil of a step-by-step motor in an electric or an electronic watch.It is characterized by the fact that one or both pole pieces 4 and 4' of the coil 2 have extrusions 10 and 11 of cylindrical shape which extend perpendicular to the plane of the pole piece 4 and are intended to be introduced into corresponding boreholes in the substrate of the printed circuit 1.This arrangement is advantageous since the extrusions can be produced by stamping before the heat treatment of the pole pieces, which eliminates the stresses which might, upon the mounting of the coil, destroy the magnetic qualities of the materials.

Abstract: The device includes a tubular connector traversed by a bore designed to house two optical fiber terminations to be connected, said terminations being composed of three spacing rods tangential to one another and to the fiber and a base provided with a stop shoulder. Countersunk holes are formed at the periphery of the connector so as to leave only thin walls or webs; these are deformed towards the axis of said connector so as to exert an elastic pressure on the terminations of the fibers, which are guided axially and positioned angularly with respect to one another by pins extending inside the bore and engaged in the grooves formed by two adjacent spacing rods of said terminations. The device is aplied to optical transmissions and notably in telecommunications.
