Patent ID: 6982393

Claim:
A lever fitting-type power supply circuit breaker, comprising: a first connector housing comprising a lever provided for moving between an operation start position and an operation completion position; and a second connector housing fittable to the first connector housing, wherein the first and second connector housings individually provide power terminals forming a power switch therein, fitting sensing terminals forming a fitting sensing switch are individually provided in the lever and the second connector housing, the fitting sensing terminal provided in the second connector housing is formed of a pair of male terminals, and the fitting sensing terminal provided in the lever is formed of a short pin, and when the lever is operated from the operation start position to the operation completion position in a state where the first and second connector housings are set at a temporal connector-fitting position, the first and second connector housings move from the temporal connector-fitting position to a connector-fitting position, and the power terminals are brought into contact with each other to turn ON the power switch, and thereafter, both of the fitting sensing terminals are brought into contact with each other to turn ON the fitting sensing switch, and a power supply circuit is brought into a conductive state by the turning ON of the fitting sensing switch.
