Abstract: A conduit sealing assembly for sealing a conduit for carrying high voltage wiring from a neon tube through a backing panel of the neon display includes a hollow connector member for securing to the backing panel so as to project through an opening in the panel. One end of the connector member on the rear side of the panel is secured to a conduit for guiding the wiring from the panel for connection to a power supply. A hollow sealing plug is secured in the opposite end of the connector member, and a hollow insulating tube for guiding wiring from the neon tube through the backing panel has one end inserted into the connector member through the plug member, which seals against the surface of the tube to provide a weather proof seal.

Abstract: A system for the insulated support of neon lights comprising a cylindrical glass cup having different diameter, longitudinal intersecting bores for receiving and securing together the respective ends of a cylindrical neon tube electrode and the cylindrical end of glass encased high voltage wire. A resilient O-ring encircles and holds together the respective end of the electrode and glass sleeve and the combination is slidably moved into the cylindrical insulating cup, with the O-ring being compressed between the inner surface of the cup and the outer surfaces of the electrode and glass sleeve, securing the combination within the cup.
