Coil body, for an inductive electrical component, is composed of a malleable thermoplastic material at low temperatures, and a heat-setting material to resist high temperatures, formed by multi-component injection molding

摘要

The coil body (20) is composed of two different plastics materials. They can be in a combination of thermoplastic materials which can be shaped again at a low and at a high temperature, or a combination of a thermoplastic material and a heat-setting material (26). The contacts (24,25) are partially embedded at the wound coil zone within the heat-setting material, or the thermoplastic material (27) which can be reshaped at low temperatures. The heat-setting material is at least partially shrouded by the malleable thermoplastic at low temperatures at the contact bar. The coil body is produced by injection molding, structured for the injection of two different materials.
