PRIMARY COIL INJECTION MOLDING FOR TRANSFORMER

摘要

The present invention relates to an integral type injection molding for receiving a plate-shaped primary coil (22) for a transformer. The integral type injection molding includes: a support portion (10) formed in a brick shape, in which a plurality of holes penetrating in a vertical direction are aligned and a plurality of terminals (12) are inserted into the plurality of holes; and a receiving portion (20) extending in a disk shape having a central opening on an upper front surface of the support portion (10), in which the receiving portion (20) is hollowed, an upper surface and a lower surface of the receiving portion (20) are partially opened and the primary coil (22) is accommodated in the receiving portion (20). Portions between a plurality of terminals (12) on the upper surface of the support portion (10) are removed by a predetermined depth. A plurality of separators (14) are formed on a bottom of the portions removed by the predetermined depth so that electric wires for applying AC voltage based on the primary coil (22) and electric wires for grounding are separated by the plurality of separators (14). The electric wires are wound on upper ends of the plurality of terminals (12) or wound on lower ends of the plurality of terminals (12) through a plurality of grooves (16) formed at regular intervals in a rear surface of the support portion (10).;COPYRIGHT KIPO 2019
