Publication number: 20180183180Abstract: A lever-type connector includes first and second connectors, and a lever member. The first connector includes a cam pin. The second connector is connected to a cable and is fitted to the first connector. The lever member includes a body and an operating part, where a cam groove into which the cam pin is inserted is formed in the body, and the operating part is contiguous to the body and is used for performing a rotating operation. The lever member is rotatably attached to the second connector and causes the first connector and the second connector to be fitted together by rotating from an initial position to a final fitting position. When the lever member is rotated, a tip of the operating part moves through a space (situated on the cable side with respect to a front face of the second connector) from which the cable is led out.Type: ApplicationFiled: December 18, 2017Publication date: June 28, 2018Inventors: Takayoshi Endo, Yoshimitsu Hashimoto, Hiromichi Ide
