Abstract The method of making a barrier strip wherein an insulator body is formed of a thermo plastic material, the insulator body having a stressing wall therein; and an electrically conductive metal conductor clip is formed with a resilient pre-stressing section; assembling the conductor clip with the insulator body in such fashion that the clip pre-stressing section is placed under a distorting force by engaging it with the stressing wall of the insulator body; heating the assembly to place the insulator body in a pliable state so that the stored force in the pre-stressing section of the conductor clip is relieved by the movement of the clip into the pliable plastic body; and cooling the assembly to provide a close mechanical interlock between the insulator body and the conductor clip. A novel barrier strip assembly results from the above method.
A terminal strip comprising an elongated strip of electrical insulating material with spaced apart substantially parallel barrier walls forming a stall therebetween; said stall having a hole therethrough and a cam track in said hole which spirals along the sidewall of the hole; and a conductor clip of resilient electrically conductive material having a top seated on the top of said strip and a downward extending tail with a pair of flat ears extending sidewise in opposite directions; said ears resting against said cam track such that said clip is adapted to be twisted to effect movement of said ears along said cam to a stressed position.
