Abstract
Discussed are rational, economical production methods for inductive components. Compared to prior methods, those addressed herein are significantly simplified processes in which exact positioning of the connections is possible. Among actions contemplated in exemplary versions of the method are providing a mold comprised of aluminum alloy, inserting a magnet core of the inductive component, and filling the closed mold with a molten hot-melt adhesive preferably comprising a polyamide base.
Claims8
Method for producing inductive components comprising:
- a. providing a metallic mold;
- b. inserting into the mold (i) a toroidal core comprising metal alloy and with at least one winding and (ii) a winding connection, the winding connection being led out of the mold before the toroidal core is inserted;
- c. closing the mold;
- d. filling the mold with a molten, thermoplastic hot-melt adhesive material under pressure;
- e. cooling the mold;
- and
- f. opening the mold and withdrawing the molded inductive component.
