Abstract

A sealed cable splice is disclosed for use in connecting electrically controlled sprinkler valves or other electrical or electronic devices to a control unit. A dual conductor polarity-keyed cable is stripped of its insulation at the end of the cable exposing the bare conductors which are then inserted into a polarity-preserving matching hole in the end of the splice. The exposed conductor enters into a socket area and then into an interior chamber of the splice where it is cinched by a electrical connector that allows a wire to be inserted but not removed. The insulation from a second cable is removed at the end of that cable and is inserted into the other side of the splice in a similar manner. Connection is now made between the two cables. The splice, has previously been filled with a displaceable sealant so that when the conductors are inserted into the splice, the sealant is displaced and forms a seal around the cables and the electrical connection. Also provided is a shorting switch which makes an electrical short between the two conductors of the cable. This provides an electronic signal to the control unit identifying the wires being connected, and eliminating the need for premarking or color coding wires.
