Abstract

A clamping mechanism for use with a terminal secured to a battery post. The terminal includes a first end securing a terminal line, a substantially annular shaped post fitting proximate a second end, and which includes a pair of spaced apart guide walls from which extend first and second spaced apart and extending legs. The clamping mechanism has a body supported in laterally traversable fashion upon the first terminal leg, an elongated aperture defined therethrough permitting the body to be seatingly engaged through a terminal post extending upwardly from the first leg. The body fixedly engaging the second terminal leg. A pair of angling guides extend along the walls defining the aperture. A nut assembly is threadably engaged over the terminal post and includes a pair of additional guides which inter-engage the aperture angling guides along a traveling direction of the slotted portion. The nut assembly is rotated between first and second opposite and translating directions along the post such that the inter-engaging guides actuate the body between loosened and tightened positions in a controlled manner and with a controlled degree of clamping and spring back forces.
