[0054]
As described above, the present embodiment has the following effects.
(1) In the connector assembly 17, the sensor part 41, the connector part 42, and the power feeding part 43 are integrally formed. Therefore, the number of steps for assembling the actuator device 9 is reduced, and the actuator device 9 can be easily manufactured.
[0055]
(2) The third reduction gear 16 accommodates the sensor part 41 in a substantially ring-shaped recess 16a formed inside the gear part 32 and opened downward. Accordingly, a space for accommodating the sensor 44 can be provided inside the gear portion 32 of the third reduction gear 16, and the actuator device 9 can be reduced in size.
[0056]
(3) The connector assembly 17 includes a sensor portion 41, a connector portion 42, and a power feeding portion 43, and is formed in a substantially L shape when viewed from above. Therefore, the outermost dimension of the connector assembly 17 is shortened, and the actuator device 9 can be miniaturized.
[0057]
(4) Even if the sensor 44 is changed, the sensor 44 and the power feeding unit 43 can be appropriately connected to the connector pins 42a to 42e depending on where the coupling parts 53a to 53c are cut. Therefore, instead of the potentiometer type sensor 44, for example, a pulse encoder type that forms a digital signal from a pulse and finely controls the rotation angle of the output shaft 35, or the rotation angle of the output shaft 35 is controlled in two ways by an on / off signal. Even a sensor of this type can be accommodated in the same connector assembly 17. Therefore, it is not necessary to change the connector assembly 17 according to the type of the sensor 44, and the versatility of the connector assembly 17 can be improved.
[0058]
(5) The connection between the sensor 44 and the power supply terminals 56 and 57 and the connector pins 42a to 42e is determined by whether or not to disconnect the connecting portions 53a to 53c that are connected in advance. Therefore, it is not necessary to connect the terminals, and the use of lead can be suppressed without using a soldering process.
[0059]
(6) The motor terminals 12 b and 12 c are formed by being bent at a position extending from the end housing 19, and an end surface on the end housing 19 side is in close contact with the end housing 19. Therefore, the actuator device 9 can be downsized in the axial direction of the motor terminals 12b and 12c.
[0060]
(7) The motor terminals 12b and 12c are in close contact with the end housing 19, and the power feeding terminals 56 and 57 feed power to the drive motor 12 with the contact portions 56a and 57b pressed against the motor terminals 12b and 12c. Yes. Therefore, when the motor terminals 12b and 12c are pressed against the end housing 19, the resonance point can be raised, and resonance near 1 kHz which is annoying can be avoided.
[0061]
(8) The drive motor 12 is fixed to the lower case 10 so that the hollow portion 18 c of the motor yoke 18 contacts the inclined surface portion 20 formed in the lower case 10. Therefore, the drive motor 12 formed in a cylindrical shape can be reliably positioned in the circumferential direction.
[0062]
(9) The wiring part 53 is connected to the sensor 44 accommodated in the sensor part 41. Accordingly, it is possible to easily check the contact position between the wiring portion 53 and the sensor portion 41 when the connector assembly 17 is formed.
[0063]
(10) The connector portion 42 includes a connector housing 40, and connector pins 42 a to 42 e are provided inside the connector housing 40. Therefore, the connector pins 42 a to 42 e can be reliably extended from a predetermined position inside the connector housing 40.
[0064]
(11) The connector pins 42a to 42e, the sensor 44, and the power supply terminals 56 and 57 extending from the power supply unit 43 are connected by a conductive plate 54 formed integrally. Therefore, the trouble of connecting the connector pins 42a to 42e and the power supply terminals 56 and 57 can be saved.
[0065]
In addition, you may change embodiment of this invention as follows.
In the above embodiment, the connector portion 42 is connected to an external terminal to receive a drive signal and to transmit information on the rotation angle of the gear detected by the position sensor portion. However, for example, a communication IC may be assembled to the actuator device 9 to receive a drive signal and transmit information on the rotation angle of the gear detected by the position sensor unit.
[0066]
In the above embodiment, the connector portion 42 includes the five connector pins 42a to 42e. However, the number of connector pins may be changed to 4 or less or 6 or more.
[0067]
In the above embodiment, the first to third reduction gears 14 to 16 are used, but the number of gears may be changed as appropriate.
In the above embodiment, the first reduction gear 14 is engaged with the second reduction gear 15 and the second reduction gear 15 is engaged with the third reduction gear 16. However, the first reduction gear may be assembled so as to be simultaneously meshed with the second reduction gear and the third reduction gear.
[0068]
In the above embodiment, the third reduction gear 16 is formed with the male output shaft 35 protruding upward from the upper shaft 33. However, the upper shaft 33 has a female output shaft recessed. It may be.
