Abstract

The invention relates to a coil former (1) for an electrical coil assembly (2), wherein the coil former (1) has a winding-holding region (3) for at least one peripheral segment of a coil winding (4),which winding-holding region (3) is bounded by a winding-holding region inner surface (5) for contact with an innermost winding layer (6) of the coil winding (4) and at least one first end piece (7) protruding from the winding-holding region inner surface (5). According to the invention, an at least partially surrounded fluid-holding reservoir (9) is arranged on a side of the first end piece (7) facing away from the winding-holding region (3), the fluid-holding reservoir (9) is connected to the winding-holding region (3) by a fluid passage opening (10), and the fluid passage opening (10) is arranged adjacent to the winding-holding region inner surface (5).

Description

technical field [0001] The invention relates to a coil holder according to the preamble of claim 1 . Background technique [0002] It is known that, in coils from the field of electrical technology, the actual coil winding is arranged on an insulating material part, which is referred to as a coil carrier. Such a coil carrier supports the winding process by helping, for example, to position the individual windings of the coil winding and to follow the desired shape of the coil more precisely. Furthermore, when the coil is arranged on a magnetic core or a simple core, the coil carrier at least partially electrically insulates the coil winding from the core and protects the core from mechanical loads when the coil winding is wound, mechanical loads It may cause deterioration of the magnetic properties of the core. [0003] Of course, cavities between the coil windings and the core or coil support can hardly be avoided. These cavities impair the heat transfer from the coil wi...
