Abstract: An electrical connector is disclosed for luminous displays having one or more gaseous electric discharge tubes provided with electrode contact bearing ends and disposed within a letter or sign housing mounted at the exterior side of a building wall. An electrical housing for a high tension transformer and electrical raceway is mounted at the interior side of the wall and rigid metal conduits extend through the wall and have their opposite ends secured to and in communication with the interiors of the letter and transformer housings for accommodation of a high tension conductor.

Abstract: An electrical connector is disclosed for luminous displays having a gaseous electric discharge tube within a tube housing. The structure includes a connector housing adapted for mounting within the tube housing and for receipt of a high-tension wire. A tubular dielectric member dimensioned for receipt of the electrode bearing end of an electric discharge tube is carried by the connector housing for longitudinal reciprocation through a wall thereof with proximal and distal ends of the member positioned respectively within and externally of the connector housing. The dielectric member is mounted for reciprocation between extended and retracted positions of its distal end with respect to the connector housing wall and such distal end is open for telescopically receiving the electrode bearing end of the electric discharge tube. A spring urges the dielectric member to its extended position and an electric contact is carried within the member for engagement with the electrode contact on the tube end.
