Abstract
To connect a potentiometer (2) and a brush holder (1) of a servomotor of a throttle-valve actuator for a motor-vehicle engine with actuating electronics, use is made of a conductor bridge (3). This has supports (8, 9), by means of which it is supported in the throttle-valve actuator. The conductor bridge (3) is furthermore provided with two rigid conductor bars (4,5) for supplying energy to the servomotor and conductors for making contact with conductor tracks (21-24) of the potentiometer. The two conductor bars (4, 5) and the conductors are each connected to a plug pin (11-16) of a plug socket (10) of the conductor bridge (3).
Claims9
Throttle-valve actuator for a motor-vehicle engine, which has a servomotor to be supplied with electrical energy and, spatially separate from the latter, a potentiometer for determining the position of a shaft of the throttle valve, characterized in that the throttle-valve actuator has a conductor bridge (3), which is supported firmly in the throttle-valve actuator by supports (8, 9) and has two rigid conductor bars (4, 5) for supplying energy to the servomotor and conductors (28) for making contact with conductor tracks (21-24) of the potentiometer, and in that the two conductor bars (4, 5) and the conductors (28) are each connected to a plug pin (11-16) of a plug socket (10) of the conductor bridge (3).
Throttle-valve actuator according to at least one of the preceding claims, characterized in that the conductors (28) are seated by means of flexible connecting lugs (17-20) on the conductor tracks (21-24) of the potentiometer (2) and are connected to these by a respective laser weld.
Throttle-valve actuator according to at least one of the preceding claims, characterized in that the conductor bars (4, 5) end with two contact posts (25, 26) in the plastic body (6) associated with the servomotor, and the servomotor has two contact lugs, which rest at an acute angle against these contact posts (25, 26) and allow insulation displacement connection.
Throttle-valve actuator according to at least one of the preceding claims, characterized in that the plug pins (11-16) are arranged in an outer connector socket projecting in a sealed manner from the throttle-valve actuator.
