A plurality of inserting openings are provided in the insulating body. The contact member comprises a busbar and a wire connection clamp. The actuation lever comprises an actuation portion for cooperating with the wire connection clamp and a flip portion, wherein the actuation portion is provided with a cam, a stop wall is provided inside the insulating body for contacting the cam. When the flip portion is flipped, the actuation lever swings and moves jointly through the contour of the cam and a contact surface of the stop wall, so a relative displacement is generated between the insulating body and the actuation lever. A contact point is generated between the surface of wire connection clamp and the actuation portion, and the position of the contact point will be changed continuously. ## Claims ### Claim 1 An electrical conductor connector, comprising: an insulating body, being formed with a plurality of inserting openings along an inserting direction, and a mounting space is formed inside the insulating body for communicating the inserting openings, so that a plurality of lead wires are capable of being inserted into the mounting space along the inserting openings respectively;
