Abstract

272,331. Spaull, B. A. May 25, 1926. Plug couplings; needlepoint couplings.-The socket part 7 of a plug-and-socket coupling is externally screwthreaded and formed with a point 8 that pierces the insulation of a conductor 10 and makes contact therewith when the socket is screwed down. The insulated wire is held in a recess 11 and is gripped by the shoulder 9 above the point 8 which enters a recess 15. The lead to the plug member 1 is similarly held and connected. The lower part C carrying the recesses 11 may be centrally pivoted to the part B carrying the sockets, so that it cam be turned to facilitate insertion of the leads. A nut on the pivot is tightened when the parts are in their working position. The heads of the sockets 7 may be accommodated in recesses in the insulating body A of the plug member.
