ABSTRACT:
A connector for connecting the broken ends of a helical conducting element has an outer sleeve of synthetic plastic material which is surrounded by an insulating coating. A pair of insulating tubular extensions having outer diameters smaller than the outer diameter of the insulating coating project from the latter in axial direction of the connector. The outer sleeve accommodates a compressible, electrically conductive helix having an inner diameter sufficiently large to receive the broken ends of the helical conducting element. The helix and helical conducting element have approximately the same pitch. The outer sleeve is provided with threaded holes which mesh with grub screws bearing upon the external surface of the helix. The insulating coating which surrounds the outer sleeve has openings which register with the holes in the outer sleeve to thereby permit the grub screws to be inserted in the holes. In operation, each of the broken ends of the helical conducting element is passed through one of the tubular extensions so that it penetrates the helix. The grub screws are rotated to compress the helix thereby causing the coils of the same to squeeze between the windings at the broken ends of the helical conducting element. As a result, a mechanical and electrical connection is formed between the broken ends. The tubular extensions serve to insulate the joint.
