Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
99 words
A probe member comprising an elongate support carrying at least one long and one short electrically conductive pin probe element in closely adjacent parallel position fOr insertion into adjacent edge perforations at a mating wire-pair location of an elongate communications cable connection module having alternately deep and shallow edge perforations for exposing adjacent contact elements, the lengths of said probes being just sufficiently less than the depth of the corresponding perforation to its contact element to provide a normally non-conductive protective spark discharge gap between said probe and said element, and including conductive means for grounding each said probe.
