Abstract

An electrical compression connector for connecting a plurality of conductors, the compression connector including a connector body of compressible material adapted to be inserted into a crimping tool having two opposed die surfaces for the compression of the connector body, the connector body including a first conductor portion and a second conductor portion. The first conductor portion includes a pair of side walls including a first side wall and a second side wall joined by a bottom wall, and a first conductor opening between the pair of side walls and the bottom wall and at least one insulation piercing member. The second conductor portion includes at least one second conductor opening extending at least partially through the connector body.

Claims (25)

1 . An electrical compression connector for connecting a plurality of conductors, the compression connector comprising:

a connector body of compressible material adapted to be inserted into a crimping tool having two opposed die surfaces for the compression of the connector body, the connector body comprising a first conductor portion and a second conductor portion;

wherein the first conductor portion comprises a pair of side walls comprising a first side wall and a second side wall, the pair of side walls joined by a bottom wall, and a first conductor opening between the pair of side walls and the bottom wall and at least one insulation piercing member; and

wherein the second conductor portion comprises at least one second conductor opening extending at least partially through the connector body, and wherein a distal end portion of each of the pair of side walls is adapted to pierce an insulation covering the first conductor when force is applied by the crimping tool to the connector body.

2 . The electrical compression connector as recited in claim 1 , wherein the at least one second conductor opening extends at least partially through a width of the connector body.

3 . The electrical compression connector as recited in claim 2 , wherein the at least one second conductor opening extends completely through the width of the connector body.

4 . The electrical compression connector as recited in claim 1 , further comprising a raised bump on the connector body adjacent the at least one second conductor opening.

5 . The electrical compression connector as recited in claim 1 , further comprising a wire clip adapted to maintain at least one second conductor in the at least one second conductor opening.

6 . The electrical compression connector as recited in claim 1 , wherein the second conductor portion comprises a hinge portion adjacent to the second conductor opening and the connector body such that when force is applied by the crimping tool to the connector body, the hinge portion of the connector body bends first to secure one or more second conductors positioned in the at least one second conductor opening to the connector body, and when additional force is applied by the crimping tool to the connector body the connector body is compressed around at least one first conductor positioned in the first conductor opening.

7 . The electrical compression connector as recited in claim 1 , wherein the at least one insulation piercing member extends from at least one of the first side wall, the second side wall and the bottom wall into the first conductor opening.

8 . The electrical compression connector as recited in claim 7 , wherein the at least one insulation piercing member is at least one of integrally and monolithically formed into the at least one of the first side wall, the second side wall and the bottom wall.

9 . The electrical compression connector as recited in claim 7 , wherein the at least one insulation piercing member is attachable to at least one of the first side wall, the second side wall and the bottom wall.

10 . An electrical compression connector for connecting a plurality of conductors, the compression connector comprising:

a connector body of compressible material adapted to be inserted into a crimping tool having two opposed die surfaces for the compression of the connector body, the connector body having a first conductor portion and a second conductor portion;

wherein the first conductor portion comprises a pair of side walls comprising a first side wall and a second side wall, the pair of side walls joined by a bottom wall, and a first conductor opening between the pair of side walls and the bottom wall and at least one insulation piercing member; and

wherein the second conductor portion comprises at least one second conductor opening extending along at least one of the side walls of the connector body, and wherein a distal end portion of each of the pair of side walls is adapted to pierce an insulation covering the first conductor when force is applied by the crimping tool to the connector body.

11 . The electrical compression connector as recited in claim 10 , wherein the second conductor opening comprises a hinge portion adjacent to the second conductor opening and the connector body such that when force is applied by the crimping tool to the connector body, the hinge portion of the connector body bends first to secure one or more second conductors positioned in the at least one second conductor opening to the connector body, and when additional force is applied by the crimping tool to the connector body the connector body is compressed around at least one first conductor positioned in the first conductor opening.

12 . The electrical compression connector as recited in claim 10 , wherein the at least one insulation piercing member extends from at least one of the first side wall, the second side wall and the bottom wall into the first conductor opening.

13 . The electrical compression connector as recited in claim 12 , wherein the at least one insulation piercing member is at least one of integrally and monolithically formed into the at least one of the first side wall, the second side wall and the bottom wall.

14 . The electrical compression connector as recited in claim 12 , wherein the at least one insulation piercing member is attachable to at least one of the pair of the first side wall, the second side wall and the bottom wall.

15 . The electrical compression connector as recited in claim 10 , further comprising a wire clip adapted to maintain at least one second conductor in the at least one second conductor opening.

16 . An electrical compression connector for connecting a plurality of conductors, the compression connector comprising:

a connector body of compressible material adapted to be inserted into a crimping tool having two opposed die surfaces for the compression of the connector body, the connector body having a first conductor portion and a second conductor portion;

wherein the first conductor portion includes a pair of side walls each having a first portion having a first thickness and a second portion having a second thickness different than the first thickness and joined by a bottom wall, and a first conductor opening between the pair of side walls and the bottom wall; and

wherein the second conductor portion includes at least one second conductor opening, wherein the first portion is thicker than the second portion and wherein the second portion comprises a distal end portion.
