Abstract
The device comprises a winding support (1) which is made of an electrically insulating material and which comprises a coil former (3), provided with a through-opening (9), and a core of a soft magnetic material which consists of two parts (15) and which comprises a limb (19) projecting through the opening of the coil former and a yoke (17) at least partly enclosing the winding support. The two core parts are attached to one another by means of a clamping bracket (21) which is made of a resilient material and which is formed as a closed ring. The construction of the clamping bracket (21) is very inexpensive and it can be very simply mounted on the assembly formed by the core (15) and the winding support (1) in that the clamping bracket consists of one piece of a resilient material which is shaped as a strip comprising barb-shaped free ends (23), which strip is bent so as to form a ring, the facing free ends engaging one another so that the ring is closed. Preferably, the clamping bracket (21) is provided with tags (27) which resiliently bear against the winding support (1) in order to counteract motions of the winding support relative to the core (15).
