A combined inductor blank with pre-bent coil

Abstract

The utility model discloses a combined inductor blank of coil pre-bending, which comprises a base, a double-winding coil accommodated in the inner wall surface of the base, and a cover body filled in the inner wall of the double-winding coil and covering the top surface of the base. The two ends of the inner coil in the double-winding coil are vertical, and the two ends of the outer coil are pre-bent and fitted in the groove of the base. In the utility model, the terminals of the outer coil in the double-winding coil are pre-bent, the inductor blank obtained is limited by the bent part of the outer coil, higher structural strength is obtained, the terminals of the inner coil are bent inward in the subsequent process, the force acts on the inside of the inductor blank, and damage to the surface of the inductor blank is avoided, so that the rate of defective products is greatly reduced.
