Abstract:
A jumper cable, comprising:a first and second electrical cable member having opposed ends;said first electrical cable member including:a positive cable element and a negative cable element;a pair of terminal clamps electrically connected to one end of said first electrical cable member;a first coupling on the other end of said first electrical cable member;said second electrical cable member including:a positive cable element and a negative cable element;a pair of terminal clamps electrically connected to one end of said second electrical cable member;a second coupling on the other end of said second electrical cable member;said first and second couplings adapted to be connected together to effect the electrical connection between said first and second cable members;said first and second couplings having a lockout means for preventing physical and electrical connection between said first and second electrical cable members;said lockout means in said couplings including:a blade slidably mounted in said coupling having an aperture;a solenoid to positively lock said blade;a diode electrically connected to said solenoid for permitting flow of current between said positive and negative cable elements in one direction to energize said solenoid and unlock said blade to allow physical and electrical connection between said first and second couplings.
