Abstract
A water seal between insulated electrical conductors connected to an underwater device such as a light and the entrance to a conduit containing the conductors is provided. The seal may be installed in existing pools when electrical cable is run through a conduit to the pool or may be installed over existing electrical cable passing through a conduit to a pool by using a split plug. The seal may also be provided by the manufacturer of apparatus for use in pools by forming a plug at a selected position on electrical cable that is attached and sealed to an electrical device such as a light.
Claims19
A plug to form a water seal between a selected conduit having an inner surface and a selected electrical cable passing through the conduit, comprising:
- a cylinder having end surfaces, a cylindrical surface, and a diameter adapted to place the cylindrical surface in sealing contact with the inner surface of the selected conduit;
- and
- a cylindrical opening passing through the cylinder in a direction so as to intersect the end surfaces, the cylindrical opening having a diameter adapted to place the cylindrical opening in sealing contact with the selected electrical cable.
Apparatus for underwater lighting, comprising:
- a light;
- an electrical cable and an electrical connection between the cable and the light, the connection being sealed and electrically insulated from a surrounding liquid;
- a plug formed and sealed around the electrical cable at a selected distance from the connection, the plug having a cylindrical surface and being adapted to form a water seal between a conduit having a selected inside diameter and the cylindrical surface of the plug.
