ABSTRACT:
A terminal connector clamp includes opposing, first and second terminal connector flanges and aligned apertures in the flanges adapted for the reception of a connecting shaft. A connecting shaft having a long axis is adapted for placement through the apertures and has at one end a stop member adapted to engage an outside surface of the first connector flange. A first cam member is operatively connected to an opposite end of the connecting shaft and is rotatable substantially about the long axis of the connecting shaft. A second cam member abuts an outside surface of the second connector flange and has a second cam surface, the second cam surface being substantially juxtaposed to the first cam surface. Rotation of one of the first cam member and second cam member causes sliding contact between the respective cam surfaces, and axial movement of the second cam member and the second connector flange away from the first cam member and toward the first connector flange to close the connector flanges against the terminal post. The invention can be provided as an add-on device for existing terminal connector clamps, as an integral terminal connector clamp construction, or a battery cable construction. A method for practicing the invention is also disclosed.
