ABSTRACT:
An attachment for installing a solderless connector to wire ends to form an electrical connection using with a rotary hand held tool is described. The attachment has a spindle member held by the tool. The spindle has a cylindrical member attached to the spindle having a frustoconical opening sized to accept and surround a portion of a solderless connector. The frustoconical opening has a plurality of detents which hold the solderless connector firmly and apply sufficient torque to the solderless connector to twist the wires inserted into the solderless connector together when the solderless connector is rotated by the tool. The detents will release their grasp on the solderless connector when sufficient twisting has been applied to the wires to electrically connect the individual wires but prior to the point at which the wires are twisted beyond their elastic limit.
