Patent ID: 8905770

Claim:
A connector device, comprising: a device side connector mounted on a device and including a first connection terminal; a power-supply side connector on an end of a power-supply side wire and including a second connection terminal, the power-supply side connector being connectable to the device side connector so that the second connection terminal connects to the first connection terminal to form a power supply circuit; an interlock circuit for switching the power supply circuit between a conductive state and a cut-off state, the interlock circuit including at least one male tab provided in the recess of the device-side connector and at least one intermediate terminal provided in the power-supply side connector; threadedly engageable connecting members mounted on the device and on the power-supply side connector for moving the power-supply side connector relative to the device side connector between an initial connection position where the first and second connection terminals are connected and the interlock circuit is in the cut-off state and a full connection position where the first and second connection terminals are connected and the interlock circuit is in the conductive state; and a partial locking mechanism provided between the power-supply side connector and the device side connector for preventing further separation when the power-supply side connector is separated to the initial connection position and the threadably engageable connecting members are separated from each other, and enabling the power-supply side connector to be separated completely when a specified force or larger is applied to the power-supply side connector.
