Abstract
Abstract A spring actuated battery clamp has a pair of cooperable clamp members disposed in side-by-side relation, one of the clamp members being adapted to be connected to the end of a battery cable. The clamp member includes a torsion spring to provided clamping forces to a battery terminal post and an alignment structure for the clamping jaws is provided in the form of dove tail arrangement of a dove tail recess at the terminus of one jaw and a cooperable dove tail projection at the terminus of the other jaw. Alternatively, the dove tail structure may be provided at the opposite side of the torsion spring.

Claim 1
Independent Claim
313 words
A battery cable connector comprising: first and second arcuate jaws each comprising a periphery, first and second side faces, a first recess extending between said first and second side faces facing the like first recess to form a generally cylindrical first bore for receiving a battery terminal post, a second recess spaced from said first recess and each extending between said first and second side faces and facing the like second recess to form a generally cylindrical second bore, a third recess in said periphery extending between said first and second side faces, and a groove in said first side face extending from said second recess to said third recess; a pair of operating arms, each of said operating arms connected to a respective arcuate jaw, said operating arms extending divergently from said first and second arcuate jaws; a spring including a spring coil mounted in said second cylindrical bore and a pair of spaced apart spring arms connected to said spring coil and located in respective ones of said grooves, each of said spring arms including a distal end portion extending at approximately a right angle thereto and located in and extending along and providing even forces along the length of the respective third recess; said spring mounted to normally urge said jaws towards one another, and second operating arms movable towards one another against the force of said spring to open said jaws; connection means on one of said operating arms for connecting a battery cable thereto; and alignment aiding means including a first distal end on said first arcuate jaw, a second distal end on said second arcuate jaw, a tapered projection extending from said first distal end towards said second distal end, and recess means defining a tapered recess in said second distal end receiving and maintaining said tapered projection therein to aid in maintaining alignment of said jaws.
