Abstract

An electrical wire connector for electrically coupling together a plurality of electrical wires, which comprises a bridging member having a midsection interposed between a pair of sectional ends each having a lower jaw element integral thereto and an upper jaw element pivotally connected thereto to collectively form a clamp mechanism for receiving a bare portion of electrical wire. A torsion spring positioned between the lower and upper jaw elements serves to supply a downward clamping force that retains the electrical wire within the clamp mechanism. The clamp mechanism further includes a plurality of slots integrated within the structure of the lower and upper jaw elements for accepting therewithin an extended section of the bare portion of electrical wire to effect resistance of tensional forces applied thereto so as to provide for a permanent-like connection that maintains continuity through the electrical wire connector.

Claims

7. The electrical wire connector as set forth in claim 1, wherein said lower and upper jaw elements respectively comprise lower and upper hinging elements each having an aperture extending therethrough for receiving therewithin a pin to allow pivotal movement of said upper jaw element relatively from said lower jaw element.

8. The electrical wire connector as set forth in claim 7, wherein said upper jaw element comprises a cantilevered arm integrally connecting to and extending from said upper hinging element.

9. The electrical wire connector as set forth in claim 1, wherein said upper jaw element comprises an upper planar component having first and second edges, a square-shaped end with a pair of corners and an arcuate-shaped end, said upper planar component further comprising a perimeter wall extending downwardly from said first and second edges and said square-shaped end to form an open-ended cavity.

10. The electrical wire connector as set forth in claim 1, further comprising a flexible insulating sleeve slidably positioned over an assembly comprising said bridging member and said clamp mechanisms, wherein said flexible insulating sleeve extends equal distantly beyond a pair of lower nose segments of the sectional ends a predetermined amount.
