An inert gas lighting system, which system has a plurality of letters or characters arranged in sequence and a high tension dielectric terminal box operatively disposed between adjacent pairs of said characters. Each box has a terminal block centrally disposed therein for the attachment of high voltage cable leads thereto connecting adjacent letters. The use of thermosetting V5 plastic for the construction of the terminal box enables the entire unit to be molded, sealed and grounded as required. Installation, maintenance and repair of such signage is enhanced.

A system for wiring the secondary circuitry in an inert gas sign set-up without requiring an external sign cabinet to protect the set up from adverse weather conditions, said system comprising: a plurality of discrete sign characters disposed in a sequence, each of said characters having a tube of preselected shape operatively associated therewith, each said tube having a first end and a second end and being filled with an inert gas capable of glowing when excited by the application of high electrical voltage thereto; a plurality of discrete cable means, each having a proximal end and a distal end, each said proximal end of each said cable means being operatively connected to a different one of said tube first ends and said tube second ends; a high tension terminal box operatively interposed between each pair of adjacent sign characters in said sequence and having a housing member having a sidewall and a bottom, access means defined through said sidewall in equispaced relationship to each other, a terminal block centrally disposed within said housing member in spaced insulated relationship to said sidewall, said terminal block having first and second binder posts disposed therein in electrical communication with each other, each said binder post being adapted to receive and secure said distal end of said cable means extending from a different one of said adjacent sign characters to serially connect a pair of adjacent sign characters therethrough when said distal ends of said cables are secured thereto; a high voltage transformer having two posts; cable means connecting one of said transformer posts to said first end of said tube in the first character in said sequence and connecting the other of said posts to the said second end of said tube in the final of said characters in said sequence to complete the circuit through said sequence; and means for controlling said transformer to selectively energize and deenergize said inert gas in said tubing.
