Title: Wire nut with self locking hot wire insert

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to wire nut electrical connectors and more particularly pertains to a new Wire Nut With Self Locking Hot Wire Insert for providing a connector which allows an electric wire to be safely removed from other wires for testing without disturbing the electrical bond needed by the branch wires. 
     2. Description of the Prior Art 
     The use of wire nut electrical connectors is known in the prior art. More specifically, wire nut electrical connectors heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art wire nut electrical connectors include U.S. Pat. Nos. 5,112,252; 5,252,779; 4,684,195; 5,314,350; 4,415,215; and 4,133,596. 
     While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new Wire Nut With Self Locking Hot Wire Insert. The inventive device includes an insert wire socket, a release wire socket, an insulating means, a conductive means, a retainer means and an insulating pad means. 
     In these respects, the Wire Nut With Self Locking Hot Wire Insert according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of providing a connector which allows an electric wire to be safely removed from other wires for testing without disturbing the electrical bond needed by the branch wires. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of wire nut electrical connectors now present in the prior art, the present invention provides a new Wire Nut With Self Locking Hot Wire Insert construction wherein the same can be utilized for providing a connector which allows an electric wire to be safely removed from other wires for testing without disturbing the electrical bond needed by the branch wires. 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new Wire Nut With Self Locking Hot Wire Insert apparatus and method which has many of the advantages of the wire nut electrical connectors mentioned heretofore and many novel features that result in a new Wire Nut With Self Locking Hot Wire Insert which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art wire nut electrical connectors, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises an insert wire socket, a release wire socket, an insulating means, a conductive means, a retainer means and an insulating pad means. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new Wire Nut With Self Locking Hot Wire Insert embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the Wire Nut With Self Locking Hot Wire Insert 10 comprises an insert wire socket 22, a release wire socket 20, an insulating means 30, a conductive means 32, a spring retainer means 44, and an insulating pad means 42 where the insulating means 30 is a housing which holds the insert wire socket 22, the release wire socket 20, the conductive means 32, and the retainer means 44 and where the insert wire socket 22, the release wire socket 20, the conductive means 32, and the retainer means 44 are all electrically connected to one another and the insulating pad means 42 is fixedly fastened to the retainer means 44 and substantially prevents electrical contact therewith. 
     As best illustrated in FIGS. 1 through 6, it can be shown that the insulating means 30 is shaped similarly as any old and well known wire nut 17 and hence is generally conical in shape. The conductive means 32 is further defined as including a tapered screw thread 34 for receiving a plurality of branch circuit wires 14 and is encompassed by the insulating means 30. At an upper end of the tapered screw thread 34 is an integrally continuous extension protrusion which further defines and includes the insert wire socket 22 where the insert wire socket 22 is more specifically defined as an aperture within the integrally continuous extension protrusion. 
     The insulating means 30 further includes a vertical aperture and a horizontal aperture where the horizontal aperture retainably holds the spring retainer means 44 and the vertical aperture provides tool access to an upper section of the spring retainer means 44 and the upper section of the spring retainer means 44 is fixedly covered by the insulating pad means 42. 
     The spring retainer means 44 further includes a sharp edge 40 at a protruding end of the spring retainer means 44 and the sharp edge 40 is flat on a side of the spring retainer means 44 facing the tapered screw thread 34 and is beveled from the opposite side of the spring retainer means 44 to the flat side. Referring to FIGS. 5 and 6, the spring retainer means 44 is spring biased to deflect downward toward the tapered screw thread 34 and the sharp edge 40 is shaped to slidingly allow a hot wire 12 to be slidingly inserted past the sharp edge 40 and by combination of spring bias and sharp edge 40, the hot wire 12 is self locked from disengagement. 
     The hot wire 12 is a typical electrically conductive wire with an insulation coating surrounding it and when the insulation is removed, a stripped wire 52 is exposed such that for the preferred embodiment, the spring retainer means 44 more particularly cuts into the hot wire 12 and the hot wire 12 is spring biasedly forced to make cylindrical contact with the insert wire socket 22. 
     The insulating means 30 the insert wire socket 22, the release wire socket 20, the conductive means 32, and the retainer means 44 together comprise and are redefined as a self locking wire nut 13. 
     In use, an electrical supply 11 is electrically connected to an electrical circuit having any number of typical components such as a control means 15, like a switch 16, and branch circuit wires 14 which are typically held together by wire nuts 17. A typical application for this electrical circuit is in a house where a &#34;neutral&#34; wire 18 (usually white in insulation color) and the hot wire 12 (usually black in insulation color) are employed for transfer of electrical power from the electrical supply 11 to the electrical circuit. The inventive device is the self locking wire nut 13 which, referring to FIGS. 5 and 6, allows for easy wire assembly 50 or easy wire disassembly 60 with the additional use of a removal means 62 such as a flat head screw driver. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
