Lever actuated connector and connector assembly

A connector assembly, comprising:

• a cap connector including an interlock connector retaining a plurality of ends of a pair of first conducting wires, a pair of terminals fixed to a plurality of ends of a pair of second conducting wires, and a mating housing accommodating the interlock connector and the pair of terminals and having a first boss protruding from an outer wall face of the mating housing;
• and
• a plug connector detachably matable with the cap connector and including:
• an interlock busbar capable of being inserted into the interlock connector to short-circuit the first conducting wires;
• a clip spring adapted to pinch the terminals with a spring force to short-circuit the terminals;
• an inner housing retaining the clip spring and having a catching protrusion protruding outward from the inner housing;
• an outer housing accommodating and retaining the interlock busbar, accommodating the inner housing retaining the clip spring slidably in a direction of mating with and a direction of unmating from the cap connector, and formed with a releasing protrusion adapted to be positioned in the clip spring to keep the clip spring open when the plug connector is unmated from the cap connector, and having a second boss protruding from an outer wall face of the outer housing;
• and
• a lever adapted to be operated to perform mating with and unmating from the cap connector, the lever includes a cam groove for receiving the first boss, a boss rotation hole for receiving the second boss, and a catching protrusion sliding hole for receiving the catching protrusion, a first turning operation of the lever during an unmating operation from a fully mated state with the cap connector causes a short-circuit removing motion extracting the interlock busbar from the interlock connector to remove the short circuit of the first conducting wires, and a second turning operation of the lever during the unmating operation after the short-circuit removing motion causes a spring opening motion moving the releasing protrusion into the clip spring to open the clip spring by moving the outer housing in the direction of unmating while pushing the catching protrusion in the direction of mating to block the inner housing from moving in the direction of unmating.
