Abstract: An electrical cable connector configured to physically and electrically mate and connect with an indentical such electrical cable connector. The cable connector includes both male and female connectors corresponding to each circuit lead of the cable configured to mate and electrically connect with the female and male connectors, respectively, corresponding to like circuit leads of another identical cable connector. The male connector is electrically insulated from its associated circuit lead when the cable connector is not electrically connected to a second cable conector and is electrically connected to the circuit lead when the cable connector is electrically connected to a second cable connector. The male connector is preferably a pin and the female connector a socket comprising two terminals electrically insulated from one antoher. The male pin is electrically connected to one of the terminals of the female socket.
