Lever-coupling type connector

A lever-coupled connector comprising:

• a male connector having a body and latch pins extending laterally therefrom;
• a female connector having walls containing pin-guiding recesses into open ends of which the latch pins are to be received;
• a lever having cam plates disposed on opposite sides of said female connector adjacent the walls thereof and being rotatably attached thereto, said cam plates having driving cam grooves containing bottom walls defining open ends for receiving said latch pins when said lever is in its initial position wherein said open ends of said bottom walls align with said open ends of said pin-guiding recesses, said lever carrying resilient pieces formed on the bottom walls of said driving cam grooves and having initial position holding protrusions operative to extend into and engage the pin-guiding recesses of said female connector in the initial position to align the open ends of said bottom walls and said pin-guiding recesses and to prevent said lever from being rotated, said latch pins having a lateral extent sufficient when said male connector is inserted into the female connector to enter said aligned open ends of said bottom walls and said pin-guiding recesses to engage said protrusions on said resilient pieces for urging them out of said pin-guiding recesses to release said protrusions to permit said lever to rotate.
