一种电刷装置及使用该电刷装置的有刷电机

Brush device and brush motor employing same

Abstract

本实用新型提供一种电刷装置及使用该电刷装置的有刷电机,该电刷装置包括绝缘支撑件、设置于支撑件上的电刷安装架、安装到相应的电刷安装架内的电刷、用于与外部电源连接的接线端、串接在接线端与对应电刷之间的供电支路,所述电刷装置还包括安装到所述支撑件的并与所述供电支路导电连接的片状至少一接地导体,所述接地导体包括片状的固定至所述支撑件的主体部以及从所述主体部延伸出的用于与电机外壳导电连接的舌片,所述舌片具有弯折部以实现弹性压接。实施本实用新型,该接地导体方便安装,且能够容易地、可靠地通过电机外壳实现接地连接。
The utility model provides a brush device and a brush motor employing the same. The brush device comprises an insulating supporting piece, brush installation frames disposed on the supporting piece, brushes disposed in the brush installation frames, a wiring end which is connected with an external power supply, and a power supply branch circuit which is connected in series between the wiring end and the corresponding brush. The brush device also comprises at least one sheet-shaped grounding conductor which is installed on the supporting piece and is electrically connected with the power supply branch circuit. The grounding conductor comprises a sheet-shaped main body part which is fixed on the supporting piece, and also comprises a tongue piece which extends out from the main body part and is connected with a motor shell in a conductive manner. The tongue piece is provided with a bent part, so as to achieve elastic crimping. According to the utility model, the grounding conductor is convenient to install, and can achieve the grounding easily and reliably through the motor shell.
