## Abstract

A power supply circuit breaking device includes a first connector housing, a second connector housing, a main lock unit locking in a finally fitted state in which the second connector housing is completely fitted to the first connector housing, a sub-lock unit locking in a temporarily fitted state in which a part of the second connector housing is fitted to the first connector housing, a main switch unit switched on in the finally fitted state and the temporarily fitted state, and a sub-switch unit switched on in the finally fitted state and switched off in the temporarily fitted state. The sub-lock unit includes a sub-lock claw formed in the first connecter housing, and an operation portion provided in the second connector housing and having an engaging plate portion engaged with the sub-lock claw in the temporarily fitted state.

## Claims

### Claim 1

A power supply circuit breaking device comprising:
a first connector housing;
a second connector housing that is configured to be fitted to and separated from the first connector housing;
a main lock unit that is configured to lock in a finally fitted state in which the second connector housing is completely fitted to the first connector housing;
a sub-lock unit that is configured to lock in a temporarily fitted state in which the second connector housing is displaced toward a separating direction from the finally fitted state and a part thereof is fitted to the first connector housing;
a main switch unit that is configured to be switched on in the finally fitted state and the temporarily fitted state; and
a sub-switch unit that is configured to be switched on in the finally fitted state and switched off in the temporarily fitted state,
wherein the sub-lock unit includes:
a claw portion formed in the first connector housing; and
an operation portion provided in the second connector housing and having an engaging plate portion engaged with the claw portion in the temporarily fitted state.

### Claim 2 (depends on 1)

The power supply circuit breaking device according to claim 1,
wherein the engaging plate portion is provided swingably with respect to the second connector housing,
in the finally fitted state, the first connector housing is disposed on a back side of the engaging plate portion so as to restrict a swinging of the engaging plate portion,
in the temporarily fitted state, a space is formed on the back side of the engaging plate portion so as to swing the engaging plate portion, and
an engagement state in which the engaging plate portion is engaged with the claw portion is released by swinging the engaging plate portion in the temporarily fitted state.

### Claim 3 (depends on 2)

The power supply circuit breaking device according to claim 2,
wherein the second connector housing includes a swing range restricting unit that is configured to restrict a swing range of the engaging plate portion of the sub-lock unit.

### Claim 4 (depends on 1)

The power supply circuit breaking device according to claim 1,
wherein the second connector housing includes a lever rotatably supported, and
wherein fitting force and separation force are applied to the first connector housing by rotation of the lever.

### Claim 5 (depends on 4)

The power supply circuit breaking device according to claim 4,
wherein the lever supported by the second connector housing is rotated at one end of the second connector housing, and
wherein the sub-lock unit is provided at another end of the second connector housing.
