ABSTRACT:
FIELD
This invention relates to battery electrical connectors, and more particularly to such connectors useful for example in conjunction with so-called automobile batteries.
BACKGROUND
Such connectors known in the prior art include devices identical in their post and post-clamp portions with the preferred embodiment disclosed herein; however such prior art devices include wire-connecting portions for making a conventional crimping relationship rather than jawed selective wire-clamp portions; the three portions are in the same special relationship with one another as disclosed in the preferred embodiment herein, and formed like the latter from an integral biscuit-like (except for peripheral shape) flat cutout from tin-plated Alloy 260 cartridge brass sheet 0.050 inches thick.
SUMMARY
It is my conception that such an electrical connector more desirably includes integrally with its post portion a wire-clamp portion easily selectively connected mounted on a wire bundle by simple tightening of an integral clamp wall therearound.
In most preferred embodiments, the wire-clamp portion includes a pair of facing jaw surfaces, the jaws being hingedly connected through a bendable (about a longitudinal axis) wire-holding portion; each jaw includes along free edges flanges perpendicularly therefrom in directions away from the other jaw; a bolt bead cooperates with inner surfaces of the flanges of one jaw to prevent bolt turning; the jaw surface of the last-mentioned jaw lies in a plane parallel with that of symmetry of the post portion; and the jaw surface of the other jaw is the locus of lines parallel to that longitudinal axis and defining a plane at an angle of 30 degrees to that of the other before tightening through holes in the jaws of a bolt including the bolt head.
PREFERRED EMBODIMENT
My specification of a preferred embodiment follows.
