ABSTRACT:
All of the pairs of insulated telephone lines in a long line cable are spliced at the same intervals and the splices are situated in junction boxes where linemen can have access to both junctions of each pair. Each line splice consists of a metallic splice bar forced into electrical contact with each of the parallel, spaced-apart ends of the line, the splice bar and both line ends being encased in a splice body of plastic, dielectric material which is provided with an access opening through to the splice bar between the spaced apart lines. A continuity check probe of the invention includes a metallic hook-shape rod having a short finger of shape and dimension to pass through the body access opening to contact the splice bar when a parallel, spaced-apart long finger of the rod lies in parallel, adjacent relation to the splice body. The long finger of the probe rod carries a compression coil spring acting between the outer end of the long finger and the insulating body to hold the short rod finger firmly against the splice bar. The spliced line can then be tested by fastening the test instrument to the hook-shape rod.
