Abstract

A wire connector configured to connect at least two wires includes a first portion and a second portion rotatably connected to the first portion. The first portion includes a plurality of spaced apart through bores in the first main body and opposing first stops extending from the exterior surface. The second portion includes a combination insulation piercing and wire connecting member having a plurality of apertures with arcuate slots extending from each of the plurality of apertures and opposing second gripping tabs, wherein opposing second gripping tabs are located about 180° from each other. When the opposing second gripping tabs abut each of the opposing first stops, the member is in a first position where wires can be positioned into the second portion through the member.

wherein when the first and second portions are rotated relative to each other each of the opposing second gripping tabs abut each of the opposing second stops and substantially prevent further rotation of the first and second portions relative to each other, wherein when the second gripping tabs abut each of the opposing second stops the connector is in a second, closed or connecting position where the slots in the combination insulation piercing and wire connecting member pierce the insulation and engage the conductive wire.

3 . The wire connector of claim 2 , wherein the first opposing stops are located about 90° from the second opposing stops such that the connect moves from the first position to the second position with about a quarter turn of a revolution.

4 . The wire connector of claim 2 , wherein the first portion further comprises

opposing first gripping tabs extending from the exterior surface of the first main body, wherein opposing first gripping tabs are located about 180° from each other wherein the opposing second stops extend from the opposing first gripping tabs.

5 . The wire connector of claim 4 , wherein each of the opposing first gripping tabs include a surface comprising:

a first ramped surface; and

a first shoulder.

6 . The wire connector of claim 5 , wherein each of the opposing second gripping tabs include a surface comprising:

a second ramped surface; and

a second shoulder, wherein when the connector is in the second, connecting position each of the second shoulders about one of the first shoulders, wherein the abutting first and second shoulder prevent counter-rotation toward the first, open position.

7 . A toolless wire connector configured to connect at least two tracer wires, the wire connector comprising:

a first portion comprising:

a first main body having a first end and a second end and an exterior surface;

a plurality of spaced apart through bores in the first main body extending from the first end to the second end; and

opposing first gripping tabs extending from the exterior surface of the first main body, wherein the opposing first gripping tabs are located about 180°; and

opposing first stops, each of the opposing first stops extending from each of the opposing first grip tabs, a portion of each of the first opposing stops extending above the first end;

a second portion rotatably coupled to the first main body, the second portion comprising:

a second main body having an interior space;

a combination insulation piercing and wire connecting member comprising a plurality of apertures with arcuate slots extending from each of the plurality of apertures; and

opposing second gripping tabs extending from an exterior surface of the second main body, wherein opposing second gripping tabs are located about 180° from each other; and

wherein when each of the opposing second gripping tabs abut each of the opposing first stops and substantially prevent further rotation of the first and second portions relative to each other, wherein when the second gripping tabs abut each of the opposing first stops, the combination insulation piercing and wire connecting member is in a second, closed or connecting position where the slots in the connecting plate pierce the insulation and engage the conductive wire.

8 . The toolless wire connector of claim 7 , wherein the first portion further comprises:

opposing second stops spaced from the opposing first stops, the opposing second stops having a portion of each of the second opposing stops extending above the first end, wherein the opposing second stops are located about 180° from each other;

wherein when the first and second portions are rotated relative to each other each of the opposing second gripping tabs abut each of the opposing second stops the connector is in a second portion wherein each of the plurality of through bores in the first portion is aligned with each of the apertures in the connecting plate such that insulated wires can be inserted into the interior space of the second portion from the through bores of the first portion.

9 . The toolless wire connector of claim 8 , wherein the first opposing stops are located about 90° from the second opposing stops such that the connect moves from the first position to the second position with about a quarter turn of a revolution.

10 . The toolless wire connector of claim 8 , wherein the first portion further comprises

opposing first gripping tabs extending from the exterior surface of the first main body, wherein opposing first gripping tabs are located about 180° from each other wherein the opposing second stops extend from the opposing first gripping tabs.

11 . The toolless wire connector of claim 10 , wherein each of the opposing first gripping tabs include a surface comprising:

a first ramped surface; and

a first shoulder.

12 . The toolless wire connector of claim 11 , wherein each of the opposing second gripping tabs include a surface comprising:

a second ramped surface; and

a second shoulder, wherein when the connector is in the second, connecting position each of the second shoulders about one of the first shoulders, wherein the abutting first and second shoulder prevent counter-rotation toward the first, open position.

13 . A method of electrically connecting a plurality of tracer wires, the method comprising:

providing a connector comprising:

a first portion comprising:

a first main body having a first end and a second end and an exterior surface;

rotating the first and second portions relative to each other such that the opposing second gripping tabs abut the second set of stops wherein the combination insulation piercing and wire connecting member is rotated relative to the first and second tracer wires and the arcuate slots engage the first and second tracer wires to electrically connect the first and second tracer wires.

16 . The method of claim 15 , wherein the first and second tracer wires each comprise an insulating jacket along a length of each wire, wherein when the plurality of arcuate slots engages the first and second tracer wires, the plurality of arcuate slots pierce each of the insulating jackets and make contact with both of the first and second wires to electrically connect the first and second wires.

17 . The method of claim 15 , wherein the first and second portions each comprise shoulders that engage when the opposing second gripping tabs abut the second set of stops, the shoulders abut and prevent counter-rotation of the first and second portions relative to each other.
