Abstract
A control circuit device for a motor is provided with a circuit board which has an electrically-conductive terminal for electrically connecting the motor with an exterior connector, a heat radiating unit which is connected with the circuit board to radiate heat generated by the circuit board. The heat radiating unit has a convex member at a surface thereof of the side where the electrically conductive terminal is arranged. The electrically conductive terminal is integrally formed with a concave member for being engaged with the convex member. The convex member is engaged with the concave member. Thus, a heat sink can be readily mounted without increasing the cost.

A control circuit device for a motor, the control circuit device comprising:
- a circuit board which has an electrically conductive terminal for electrically connecting the motor with an exterior connector;
- and
- a heat radiating unit which is connected with the circuit board to radiate heat generated by the circuit board, wherein:
- the heat radiating unit has a convex member at a surface thereof of the side where the electrically conductive terminal is arranged;
- the electrically conductive terminal has a concave member for being engaged with the convex member, the concave member being integrated with the electrically conductive terminal;
- and
- the convex member is engaged with the concave member.
A method for manufacturing a control circuit device for a motor, the control circuit device including a circuit board and a heat radiating unit which is connected with the circuit board to radiate heat generated by the circuit board, the circuit board having an electrically conductive terminal for electrically connecting the motor with an exterior connector, the method comprising:
- a stamping process for stamping a piece of electrically conductive plate-shaped material to construct the electrically conductive terminal;
- a molding process for performing a resin-molding at the electrically conductive terminal;
- and
- a nonconducting-part constructing process for removing an unwanted portion of the electrically conductive terminal having been resin-molded to construct the circuit board, wherein
- in the stamping process, a concave member is integrally formed by stamping with the electrically conductive terminal, the concave member being engaged with a convex member arranged at the heat radiating unit.
