Drive device and drive unit

1. A drive device comprising:

a motor having winding sets in two systems;

a control portion arranged coaxially with the motor and being configured to control a drive of the motor; and

a connector portion configured to connect an external connector which is a connector of an external cable and the motor, wherein

the control portion includes a first system control portion configured to control energization of one of the winding sets, and a second system control portion configured to control energization of the other winding set,

the first system control portion and the second system control portion are mounted on one circuit board,

the connector portion includes a first system terminal connected to the first system control portion, a first system connector holding the first system terminal, a second system terminal connected to the second system control portion, and a second system connector holding the second system terminal,

an insertion/removal direction of the first system connector and an insertion/removal direction of the second system connector are the same as an axial direction of the motor,

the first system connector and the second system connector are arranged close to each other such that a long length direction or a short length direction of the frontages of the connectors are aligned on a straight line, and an interval between the connectors is smaller than a width in the short length direction of both connectors, and

the first system connector and the second system connector protrude in a direction orthogonal to the direction in which the connectors are arranged, and include protrusions for locking levers provided on the external connector.

2. The drive device according to claim 1 , wherein

the first system connector and the second system connector are arranged such that the long length directions of the frontages of the connectors are aligned.

3. The drive device according to claim 1 , wherein

the first system connector and the second system connector are arranged such that the short side directions of the frontages of the connectors are aligned.

4. The drive device according to claim 1 , wherein

a frontage shape of the first system connector is different from a frontage shape of the second system connector.

5. The drive device according to claim 1 , wherein

the first system terminal includes a first power supply terminal for supplying power to the first system control portion and first signal terminals for inputting a signal to the first system control portion,

the second system terminal includes a second power supply terminal for supplying power to the second system control portion and a second signal terminal for inputting a signal to the second system control portion,

the first power supply terminal is arranged closer to the second system connector in the frontage of the first system connector than the first signal terminal, and

the second power supply terminal is arranged closer to the first system connector in the frontage of the second system connector than the second signal terminal.

6. The drive device according to claim 1 , further comprising:

a first space being provided on an opposite side of the first system connector from the second system connector so that a first lever for engaging with the protrusion of the first system connector is switched between a locked state and an unlocked state, and

a second space being provided on an opposite side of the second system connector from the first system connector so that a second lever for engaging with the protrusion of the second system connector is switched between the locked state and the unlocked state.

7. The drive device according to claim 1 , wherein

a rib that connects the first system connector and the second system connector is formed between the connectors.

8. A drive unit, comprising:

a motor having winding sets in two systems;

a control portion arranged coaxially with the motor and being configured to control a drive of the motor;

an external connector which is connector of an external cable;

a lever provided on the external connector; and

a connector portion for connecting to the external connector; and wherein

the control portion includes a first system control portion configured to control energization of one of the winding sets, and a second system control portion configured to control energization of the other winding set,

the first system control portion and the second system control portion are mounted on one circuit board,

the connector portion includes a first system terminal connected to the first system control portion, a first system connector holding the first system terminal, a second system terminal connected to the second system control portion, and a second system connector holding the second system terminal,

an insertion/removal direction of the first system connector and an insertion/removal direction of the second system connector are the same as an axial direction of the motor,

the first system connector and the second system connector are arranged close to each other such that a long length direction or a short length direction of the frontages of the connectors are aligned on a straight line, and an interval between the connectors is smaller than a width in the short length direction of both connectors, and

the first system connector and the second system connector protrude in a direction orthogonal to the direction in which the connectors are arranged, and include protrusions for locking levers.

9. The drive unit according to claim 8 , wherein:

the external connector moves in the insertion direction with the rotation of the lever.
