Abstract

An actuator device includes a drive motor, a reduction mechanism, which includes gears, an output shaft coupled to the reduction mechanism, and a connector assembly. The connector assembly includes a sensor accommodating portion for accommodating a sensor, which detects the rotation angle of the output shaft, and a connector portion, which includes connector pins connected to an external connector, and a power supply portion, which includes power supply terminals connected to the drive motor. The sensor accommodating portion, the connector portion, and the power supply portion are integrally formed. The power supply terminals and the connector pins are formed of a single conductive plate. The connector assembly is molded using resin to integrally incorporate the conductive plate. As a result, the actuator device that is easily assembled is obtained.

Dependent claims

An actuator device, comprising:

a device housing;
a drive motor located in the device housing;
a power transmission mechanism located in the device housing and is coupled to the drive motor;
an output shaft coupled to the power transmission mechanism, rotation of the drive motor is transmitted to the output shaft via the power transmission mechanism;
a sensor for detecting the rotation angle of the output shaft;
a sensor accommodating portion for accommodating the sensor;
a connector portion including a connector housing and a connector terminal, which is incorporated in the connector housing;
and
a power supply portion including a power supply terminal, which is connected to the drive motor and supplies electric power to the drive motor,
wherein the power supply terminal and the sensor are electrically connected to the connector terminal, electric power is supplied to the drive motor from the outside via the connector terminal and the power supply terminal, and a rotation angle signal obtained by the sensor is sent to the outside via the connector terminal,
wherein the sensor accommodating portion, the connector portion, and the power supply portion are integrally formed to form a single assembly mounted on the device housing, and
wherein the power transmission mechanism includes a plurality of gears, one of the gears has the output shaft and includes a recess for accommodating the sensor accommodating portion.
