Abstract
Abstract A connector for discharge electrodes of luminous gas tubes includes an insulative barrel receiving a power cable at one end for attachment to a fixed end of a resilient contact member. The opposite end of the barrel is open and threaded, to receive the crimped and headed tip of a gas tube having electrode conductors projecting therefrom. A lock element is applied to the crimped portion of the gas tube end and is axially captured thereon so that following insertion of the tube tip and lock element into the barrel open end, a cap surrounding the gas tube engages the threads of the barrel to radially and axially retain the tube tip within the barrel interior with its electrode conductors firmly biased against a displaceable end of the resilient contact member. In an alternate embodiment, the same lock element serves to secure each of a pair of gas tube tips within a housing having a contact member provided with displaceable end segments serving to electrically join the electrode conductors of the pairs of gas tubes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
257 words
In an electrical connector for joining a first wire conductor to a second conductor as formed by one or more electrode wires projecting from the headed tip of a luminous gas tube and wherein the gas tube includes a cylindrical main body joined to a reduced dimension crimped portion terminating in the headed tip, comprising: a housing of dielectric material having first and second bores therein communicating with a cavity, threads surrounding at least said second bore, a cap having threads mating with said second bore threads and having an axial bore adapted to closely surround the gas tube main body, an axially compressible resilient contact member within said housing cavity having opposite end segments respectively engageable with the first and second conductors, a lock element removably attachable about the gas tube crimped portion intermediate the tube main body and headed tip, said lock element having a lateral dimension greater than the diameter of the gas tube main body and said bore of said cap, whereby, with said cap disposed about the gas tube main body and said lock element then attached about the gas tube crimped portion the tube headed tip is insertable within one said housing bore with the second conductor projecting therefrom engageable with one said contact member end segment to complete a circuit through the other said contact member end segment following which said cap threads are engaged with said housing second bore threads to urge said lock element to maintain said second conductor in positive abutment with said one contact member segment.
Claim 2
Dependent Claim
