Abstract

An electrical connector includes first and second pads. The first pad includes first and second grooves and the second pad includes third fourth grooves. A first insulation displacing contact extends from the first groove to the second groove. A second insulation displacing contact extends from the third groove to the fourth groove. The first and second pads are connected by a mechanical fastener. When the first and second pads are connected the first groove aligns with the third groove and the second groove aligns with the fourth groove.

First claim

What is claimed:

1. An electrical connector comprising:
a first pad having a first groove, a second groove, an electrically conductive first insulation displacing contact positioned in said first groove, an electrically conductive second insulation displacing contact positioned in said second groove and electrically connected to said first insulation displacing contact, and an opening extending through said first pad between said first groove and said second groove;
a second pad having a third groove, a fourth groove, an electrically conductive third insulation displacing contact positioned in said third groove, an electrically conductive fourth insulation displacing contact positioned in said fourth groove and electrically connected to said third insulation displacing contact, and a slot extending through said second pad between said third groove and said fourth groove;
a fastener extending through said opening and said slot to connect said first pad and said second pad, aligning said first groove with said third groove and said second groove with said fourth groove;
a spring member positioned around said fastener biasing said first pad and said second pad towards one another, said second pad being pivotable with respect to said first pad; and
a sleeve extending through said opening and into said slot receiving said fastener.

2. The electrical connector of claim 1 wherein
said first insulation displacing contact and said second insulation displacing contact are a unitary structure connected by a central portion.

3. The electrical connector of claim 1 wherein
said spring biases said second pad towards said first pad.

4. The electrical connector of claim 1 wherein
the sleeve includes a flange and a hollow cylindrical body.

5. The electrical connector of claim 1 wherein
a washer is positioned around said fastener and a nut is threaded onto said fastener, said spring being positioned between said nut and said washer.

6. An electrical connector comprising:
a first pad having a first groove, a second groove, an electrically conductive first insulation displacing contact extending from said first groove to said second groove, and an opening extending through said first pad between said first groove and said second groove;
a second pad having a third groove, a fourth groove, an electrically conductive second insulation displacing contact extending from said third groove to said fourth groove, and a slot extending through said second pad between said third groove and said fourth groove;
a fastener extending through said opening and said slot to connect said first pad and said second pad, aligning said first groove with said third groove and said second groove with said fourth groove;
a washer disposed on said fastener;
a nut threadably connected to said fastener;
a spring member positioned around said fastener between said washer and said nut biasing said first pad and said second pad towards one another, said second pad being pivotable with respect to said first pad; and
a sleeve, having a flange received by said first recess and a hollow cylindrical body extending through said opening, receiving said fastener.

7. The electrical connector of claim 6 wherein
said first insulation displacing contact comprises a first set of teeth in said first conductor groove and a second set of teeth in said second conductor groove.

8. The electrical connector of claim 7 wherein
said spring member applies force sufficient to cause at least one of said first set of teeth and said second set of teeth to pierce the insulation of an insulated conductor.

9. The electrical connector of claim 6 wherein
said first pad has a top surface that includes a first recess surrounding said opening and said second pad includes a top surface that has a second recess surrounding said slot.

10. The electrical connector of claim 6 wherein
rotation of said nut on said fastener adjusts the amount the second pad is capable of pivoting with respect to the first pad.

11. An electrical connector comprising:
a first pad having a first top surface, a first end, a second end, a first side, a second side, a first flange extending adjacent said first end, a first leg extending adjacent said second end, a first groove, a second groove, an electrically conductive first insulation displacing contact extending from said first groove to said second groove, an opening extending through said first pad between said first groove and said second groove, and a first knockout extending from said first side;
a second pad having a second top surface, a third end, a fourth end, a third side, a fourth side, a second flange extending adjacent said third end, a second leg extending adjacent said fourth end, a third groove, a fourth groove, an electrically conductive second insulation displacing contact extending from said third groove to said fourth groove, a second knockout extending from said third side, and a slot extending through said second pad between said third groove and said fourth groove;
a fastener extending through said opening and said slot to connect said first pad and said second pad; and
a sleeve extending through said opening and into said slot receiving said fastener.

12. The electrical connector of claim 11 wherein
said first flange extends approximately half the length of said first end and said second flange extends approximately half the length of said third end.

13. The electrical connector of claim 12 wherein
said first flange and said second flange at least partially horizontally align when said first pad is connected to said second pad.

14. The electrical connector of claim 11 wherein
said first pad includes a first tab extending from said first side and a first groove in said second side and said second pad includes a second tab extending from said third side and a second groove in said fourth side, said first tab mating with said second groove and said second tab mating with said first groove when said first pad and said second pad are aligned.

15. The electrical connector of claim 11 wherein
said first leg has a first inner surface and said second leg has a second inner surface angled with respect to the first inner surface and the angle between said first inner surface and said second inner surface is approximately 64 degrees.

16. The electrical connector of claim 11 wherein
said first leg is connected to said second end by a separable portion.

17. An electrical connector comprising:
a first pad having a first top surface, a first end, a second end, a first side, a second side, a first flange extending adjacent said first end, a first leg extending adjacent said second end, a first groove, a second groove, an electrically conductive first insulation displacing contact extending from said first groove to said second groove, an opening extending through said first pad between said first groove and said second groove, and a first tab extending from said first side and a first groove in said second side;
a second pad having a second top surface, a third end, a fourth end, a third side, a fourth side, a second flange extending adjacent said third end, a second leg extending adjacent said fourth end, a third groove, a fourth groove, an electrically conductive second insulation displacing contact extending from said third groove to said fourth groove, a slot extending through said second pad between said third groove and said fourth groove, a second tab extending from said third side and a second groove in said fourth side, said first tab mating with said second groove
