ABSTRACT:
An electrical connector for coupling to an insulated electrical conductor includes an insulated housing having a threaded bore therein, which bore has a tapered portion therein. An electrical conductive prong has two end portions with one end portion attached to the housing and having a second end portion protruding axially into the housing bore for receiving the end of an insulated electrical conductor. A threaded compression collar is threadedly attached in the bore and has a bore extending axially therethrough for insertion of a wire therethrough and into the housing bore and onto the pointed prong extending thereinto. The threaded compression collar has a compressed portion compressible by threading the collar into the tapered portion of the bore whereby threading the collar onto the tapered portion of the bore clamps the collar onto the wire placed therein so that an insulated wire can be rapidly connected to an electrical connector without removing the insulation from the end of the wire. The collar has the bores tapered with an expandable and compressible end so that different size wires can be inserted therethrough and guided onto the connector prong. The collar has split end portions to allow expansion or compression and can be a one piece polymer member.
