Wire Nut Electrical Connector

Abstract

The present invention relates to an electric testing assistance tool in the form a wire nut or electrical connector. The tool is a funnel shaped flame resistant and insulating device and has a top end and a bottom end with curved walls. The top end includes a central hole to receive a testing probe of a tester device. The device has an internal metal spiral thread connected to a metal ball connector. The metal spiral thread twistable about a plurality of wire end leads. The leads extending from the bottom end opening are connected to a target wiring whose electrical parameters and continuity is to be measured using the electric testing assistance tool. The testing probe can be inserted through the central hole to contact the metal ball to measure the electric parameters and continuity of the target wiring.

What is claimed is: 
     
         1 . A wire lead connector for retaining and testing at least two wire leads connected therewith, the connector comprising:
 a connector housing having an open bottom end and a partially open top end including a length therebetween;   said partially open top end comprises a central hole for receiving a testing probe of a tester device;   said bottom end having a first circumference;   said partially open top end having a second outer circumference;   said first circumference larger than said second circumference;   said connector housing tapering from said bottom end circumference to said top end circumference;   an internal metal spiral threaded and fixed into an internal surface of the connector housing comprising a cone-shaped wire spring having an open bottom end and a closed top end including a length therebetween;   said internal metal spiral tapering from said bottom end to said top end;   said internal metal spiral length less than said connector housing length;   said internal metal spiral taper corresponding to said connector housing taper;   said closed top end is spaced below and aligned with said central hole; and   at least one permanently connected wire lead integrated into the internal metal spiral and extending from the open bottom end of the connector housing, wherein the connector housing is flame-retardant in construction.   
     
     
         2 . The wire lead connector of  claim 1 , wherein said closed top end comprises a metal ball for contact with the testing probe of a tester device. 
     
     
         3 . The wire lead connector of  claim 2 , wherein said central hole guides the testing probe of a tester device to said metal ball. 
     
     
         4 . The wire lead connector of  claim 1 , wherein said connector housing is thermoplastic material including electrical insulation. 
     
     
         5 . The wire lead connector of  claim 1 , wherein said connector housing bottom end including a pair of opposing tabs extending outwardly therefrom for gripping and rotating said connector housing. 
     
     
         6 . A method for testing an electrical connection of wire leads, the method comprising the steps of:
 providing a wire lead connector for retaining and testing at least two wire leads connected therewith, wherein said wire lead connector comprises a connector housing having an open bottom end and a partially open top, and further wherein said partially open top end comprises a central hole;   providing a metal spiral thread having an open bottom end and a closed top end;   threading said metal spiral thread inside said connector housing, wherein said spiral thread closed top end spaced below said central hole;   turning said wire lead connector onto at least two wire leads;   inserting a testing probe of a tester device into said central hole;   contacting said spiral thread closed top end with said testing probe; and   determining an electrical connection of the at least two wire leads.   
     
     
         7 . The method of  claim 6 , wherein said closed top end is spaced below and aligned with said central hole. 
     
     
         8 . The method of  claim 6 , wherein said closed top end comprises a metal ball for contact with the testing probe of a tester device. 
     
     
         9 . The method of  claim 8 , wherein said central hole guides the testing probe of a tester device to said metal ball. 
     
     
         10 . The method of  claim 9 , wherein an inside wall of said connector housing is threaded for threaded engagement with said metal spiral thread. 
     
     
         11 . The method of  claim 10 , wherein said connector housing is thermoplastic material including electrical insulation.
