ABSTRACT:
The present invention relates to a connector for electrically joining two aluminum wires, end to end, and further to mechanically retain such wires against pull-out. More particularly, the invention teaches extruding an aluminum tube having a first longitudinally extending passage, a second passage beneath the first passage and vertical slot between the two which create cantilever beams which are resilient so as to exert force against the wires in cooperation with set screws bearing in against the wires from an opposite side of the tube. Further, an elongated tooth slide bar, occupying the vertical slots, provides oxide scrapping action and wire retention, also in cooperation with the set screws.
