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. The improvement of the present invention includes a dielectric conduit for the high voltage conductor and having a length and dimension for removable telescopic mounting in and support by one of the rigid metal conduits and having a right angularly related open ended dielectric receptacle or socket at its outboard end to telescopically receive one of the electric tube ends so as to support the display tube substantially parallel to a mid-plane of the letter housing, the dielectric conduit and the metal conduit cofunctioning to position and support the display tube in the letter housing substantially parallel to the center plane thereof.
