Barrel plug having insulation displacement terminals

A barrel plug for an insulated electrical cable having nonconcentric parallel conductors, comprising:

• an annular outer terminal having an outer terminal extension extending from an end thereof and terminating in a first insulation displacement terminal;
• an inner terminal located coaxially within said annular outer terminal and having an inner terminal extension extending from an end thereof and terminating in a second insulation displacement terminal;
• an insulative intermediate body located between said outer and inner terminals for holding said outer and inner terminals in a predetermined location;
• and
• an insulative housing having a first end for receiving said outer and inner terminals and said intermediate body, said first end and said intermediate body including a key structure for orienting said outer and inner terminals with respect to said first end, said housing further holding said outer and inner terminals in said predetermined location to place said first and second insulation displacement terminals in a predetermined alignment, said housing further having a second end for receiving said electrical cable, said outer and inner terminals translatable from a disengaged position to an engaged position, said first and second insulation displacement terminals displacing said insulation of said electrical cable when said outer and inner terminals are in said engaged position to make electrical contact with respective first and second conductors of said electrical cable to thereby electrically couple said outer and inner terminals to said electrical cable for transmission of electrical current therebetween.
