US Patent:

49349570, Jun 19, 1990
Filed:

Aug 15, 1989
Appl. No.:

7/394002
Inventors:

Albert V. Bellusci - Missoula MT
International Classification:

H01R 1100
US Classification:

439504
Abstract:

A clamp for battery jumper cables includes a pair of pivoted terminal gripping members with a switch and linkage arrangement connected between a conductive jaw and the conductive jumper cable to facilitate electrical connection and disconnection of the jaw and jumper cable in a controlled, spark-free manner. The linkage includes first and second lever sections pivotally connected to one of the handle sections of the terminal clamp. A first lever is operated as the clamp is grasped in the user's hand. This lever causes the over-center linkage to shift to a first over-center position, opening the switch and breaking electrical contact between the clamp and jumper cable before the jaws are forcibly opened. The over-center linkage serves to hold the switch in an open, nonconductive state even though the clamp handles are released to secure the jaws against the terminal. A second lever must be consciously pressed before the switch is allowed to move to a closed condition and electrically connect the clamp and jumper cable.
