Abstract: A lever type connector comprises two connector housings, a lever which is rotatably attached to one housing and has cam grooves, and cam pins which are provided on another housing and guided by the cam grooves. Connecting or disconnecting is assisted by rotating the lever with the cam pins and the cam grooves. A lever position, at which the cam pins can be inserted into entry gates of the cam grooves respectively, is set as a start position, and a lever position, at which the housings are completely connected, is set as an end position. An attaching position of the lever, at which the lever can be attached to the one housing, is set outside of an ordinary rotation range from the start position to the end position. According to the lever type connector, it is possible to prevent uncoupling of the lever within the ordinary rotation range.

Abstract: The present invention provides a connector fitting structure which includes a waterproof connector in which a female terminals having a plurality of sizes is arranged in a female connector housing thereof, and an opposite connector in which male terminals are arranged in a male connector housing thereof, wherein an area where a terminal having a high current-carrying capacity is arranged is formed as a projected surface relative to an area where terminals having a low current-carrying capacity low-current are arranged, and in a contact surface of the opposite connector, an area where the terminal having a high current-carrying capacity is arranged is formed as a depressed surface relative to an area where terminals having a low-current-carrying capacity low-current are arranged.
