Abstract:
1. A power supply circuit breaker, comprising: a first connector housing; a second connector housing capable of being mated with and separated from the first connector housing; a lever rotatably provided at the second connector housing, the lever being adapted to cause a mating force and a separating force to act between the second connector housing and the first connector housing by a rotation between a first operation position and a connector mating operation position, the lever being further rotatable from the connector mating operation position to a second operation position; a main circuit switch including a first main terminal provided at the first connector housing and a second main terminal provided at the second connector housing, the main circuit switch being adapted to be brought into a breaking state with the first main terminal non-contacting the second main terminal in the first operation position of the lever, and the main circuit switch being adapted to be brought into a connecting state with the first main terminal contacting the second main terminal in the connector mating operation position and the second operation position of the lever; a signal circuit switch including a first signal terminal provided at the first connector housing; and a second signal terminal provided at the lever, the signal circuit switch being adapted to be brought into a breaking state with the first signal terminal non-contacting the second signal terminal in the first operation position and the connector mating operation position of the lever, and the signal circuit switch being adapted to be brought into a connecting state with the first signal terminal contacting the second signal terminal in the second operation position of the lever; a first lock portion for locking the lever in the second operation position; a second lock portion for locking the lever in the connector mating operation position; an unlocking operation portion capable of unlocking a lock state of the second lock portion; and a rotation restricting portion configured to restrict the rotation of the lever by abutting the unlocking operation portion in the second operation position when the unlocking operation portion is operated in a direction that is the same as a direction for unlocking the lock state of the second lock portion; wherein the lever is configured to rotate but not configured to slide relative to either of the first connector housing or the second connector housing.
