Patent ID: 7872206

Claim:
A power supply circuit connector of a power supply circuit, the power supply circuit connector comprising: a first housing including: a pair of main circuit terminals configured to be connected with each other via a first switch terminal, for bringing the power supply circuit into a conduction state, and a pair of mated state sensor terminals configured to be connected with each other, for bringing the power supply circuit into the conduction state; a second housing configured to mate with or to be detached from the first housing, wherein the second housing includes the first switch terminal configured to connect the pair of the main circuit terminals by a lever being rotated to a first certain position; the lever rotatably supported to the second housing, wherein the lever includes a second switch terminal configured to, in a state that the pair of the main circuit terminals are kept connected with each other, connect the pair of the mated state sensor terminals with each other by the lever being rotated to a second certain position after the first certain position; and a mating-detaching mechanism configured to, by the rotated lever, mate the second housing with the first housing, and detach the second housing from the first housing, wherein at least a head end part of each of the mated state sensor terminals extends along a rotation track of the second switch terminal.
