  • Patent number: 11605908
    Abstract: A cam-type wire connector includes a housing, a conductor, and a lever. The housing has a plurality of insertion holes; the conductor comprises a conductive member and a leaf spring, the leaf spring has a carrier plate and a wire clamping portion that is formed with a plurality of windows. Wherein an elastic member is formed with the wire clamping portion for blocking the window; the lever has an operating portion and a toggle portion for cooperating with the leaf spring, the operating portion is constructed with a cam to allow the lever to swing without a fixed axis. When the lever is changed from an initial position to an actuate position, the elastic member is moved away from the carrier plate and an insertion channel is formed for allowing the wire to enter the window. The insertion channel is located in the interval between the second positioning surface and the fixed surface.

    Abstract: The present invention relates to an electrical conductor connector, comprises: an insulating body, a contact member and an actuation lever. 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.

  • Patent number: 11374338
    Abstract: A wire connection device includes a housing, a conductor, and a lever. The conductor is located inside the housing and has a leaf spring, a conductive member and a push-back block, and the lever is provided with a push-back notch and an actuating cam, and the lever is movably assembled in the housing so that the lever may swing against the housing so that the leaf spring is squeezed by the lever for generating a deformation. When the lever swings to an actuate position, the touch surface of the cam that touch the conductor will be changed so that the lever can be moved in a straight line against the housing simultaneously. Therefore, the push-back block can be inserted into the inside of the push-back notch.
