LARGE CURRENT CIRCUIT BOARD UNIT

摘要

PURPOSE:To provide a large current circuit board unit in which a dielectric strength of a power circuit can be largely improved and soldering of a power circuit conductor to a printed board circuit pattern is facilitated. CONSTITUTION:The large current circuit board unit comprises a printed board 1 having a control signal circuit and a copper bar insert resin molded form 3 for a power circuit in combination. The molded form is clamped by a rivet 4 passed through the molded form and the printed board at suitable positions on the printed board, and a lead terminal 5 connected to be exposed on the bar 3 of the molded form is soldered 8 to a through hole 6 of the printed board.
