Abstract

A power feeding control device is provided with a main body accommodating an electric circuit for controlling power supply to a motor vehicle from a power source. First and second cables to be connected to the motor vehicle and the power source extend from the longitudinally opposite ends of the main body, respectively. The second cable includes a plug having a plug body accommodating a second contact electrically connected to a first contact provided in the main body, and a retaining ring attached to the plug body such that the retaining ring is rotatable about an axial direction of the plug body while being restricted to move in the axial direction. By screwing the retaining ring onto a thread portion of the main body, the retaining body is detachably attached to the main body in the state that the second contact is electrically connected to the first contact.

Claims

1. A power feeding control device comprising a first cable connected to a motor vehicle and a second cable connected to a power source, each of which extends from a main body that accommodates an electric circuit for controlling power supply from a power source to a motor vehicle and includes a first contact,

wherein at least one of the first cable and the second cable is provided with:

a second contact electrically connected to the first contact of the main body; and

a retaining part detachably attached to the main body by screwing to retain the state where the second contact is electrically connected to the first contact.

2. The power feeding control device according to the claim 1, wherein one of the retaining part and the main body is provided with a protrusion part protruding toward the other thereof;

and the other of the retaining part and the main body is provided with a locking part for locking the protrusion part after the retaining part is screwed onto the main body to a position where the first contact is electrically connected with the second contact.

3. The power feeding control device according to claim 2, wherein the one of the retaining part and the main body is provided with a biasing part for biasing the protrusion part toward the other of the retaining part and the main body, and

wherein the locking part is formed to have a recessed shape into which the protrusion part is inserted.

4. The power feeding control device according to the claim 3, wherein the protrusion part is provided such that a peripheral portion thereof is covered with the one of the retaining part and the main body, and

wherein an opening for exposing the projection part inserted into the locking part is provided in a surface of the other of the retaining part and the main body.

5. A power source side cable adapted to be disconnectably connected to a main body that accommodates an electric circuit for controlling power supply to a motor vehicle from a power source and includes a first contact, the power source side cable comprising:

a plug body accommodating therein a second contact to be connected to the first contact of the main body; and

a retaining part attached to the plug body such that the retaining part is rotatable about an axial direction of the plug body while being restricted to move in the axial direction,

wherein the retaining part is attached to the main body by screwing to retain the state where the first contact is electrically connected to the second contact.

6. The power source side cable according to claim 5, wherein the retaining part is provided with a protrusion part protruding toward the main body, and

wherein the protrusion part is locked to a locking part provided in the main body in the state that the retaining part is screwed into the main body to the position where the first contact is electrically connected with the second contact.

7. The power source side cable according to claim 5, wherein the retaining part is provided with a locking part for locking a protrusion part provided in the main body to protrude toward the retaining part, and

wherein the locking part locks the protrusion part provided in the main body in the state that the retaining part is screwed onto the main body to the position where the first contact is electrically connected with the second contact.
