COMPACT MOTOR

摘要

A compact motor which avoids peeling and cracking of the circuit board wiring pattern upon bending the printed circuit board. A projecting part (13), projecting toward the bottom side of the bracket (5), is provided on the back surface (5c) of the bracket (5) of a compact motor. A board insertion groove (S) is formed between the projecting part (13) and the back surface (5c). The flexible printed circuit board (10), inserted inside the board insertion groove (S), abuts the projecting part (13) and is bent facing the back. When the printed circuit board (10) is inserted into the board insertion groove (S) and bent, the printed circuit board (10) is in a state abutting the curved part (13a) of the projecting part (13), so the curved part (13a) of the projecting part (13) regulates bending and, by doing this, stabilizes bending of the flexible printed circuit board (10).

主权项

1. For a motor for which an end part of a flexible printed circuit board abuts a back surface of a bracket fixed to a back end of a housing, and a wiring pattern of the flexible printed circuit board is connected to connection terminals projecting backwards from the bracket, a compact motor comprising:
a projecting part projecting toward an outside of a radial direction of the motor provided on the back surface of the bracket, a board insertion groove formed between the projecting part and the back surface of the bracket, and the flexible printed circuit board inserted inside the board insertion groove bent along the projecting part.
