Abstract
An actuator in the prior art includes a plug contact, which is disposed on a printed circuit board, and also includes a brush holder, which is not disposed on the printed circuit board but is electrically connected to it. This has the disadvantage of requiring additional electrical connections. In an actuator (1) of the invention, the brush holder (41) is loosely coupled to the printed circuit board (31) and secured to a housing (9), so that electrical connections of the brush holder (41) and printed circuit board (31) are produced simply and without additional means.
Claims11
An actuator (1), in particular for an assembly of a motor vehicle,
- having a unit comprising an electric motor (3), a gear (47), and a motor electronics unit (4),
- having a housing (9), which comprises a gear housing (12) for the gear (47) and an electronics housing (15) for the motor electronics unit (4),
- having a motor housing (6) of the electric motor (3), which housing is connected to the housing (9),
- having a shaft (19) of the electric motor (3), which shaft protrudes into the gear housing (12),
- having a brush holder (41) in the housing (9),
- having a printed circuit board (31),
- which is disposed in the electronics housing (15),
- which is connected to an external connection plug (37),
- which is electrically connected to the brush holder (41) and to components of the motor electronics unit (4),
- characterized in that
- the brush holder (41), for installation in the actuator (1), is loosely coupled to the printed circuit board (31).
