Abstract

Die sets for crimping busses to electrical connectors are provided. The die set includes a pair of dies where one die has a guide member for aligning the dies with the electrical connector, and the other die has a one or more indentors for impacting the electrical connector. The electrical connectors include a guide hole that receives the guide member.

First claim

What is claimed is:

1. A die set for power crimping tools used to impact objects comprising:
a first die including a first body having a first face plate and a guide member extending from the first face plate, the guide member having a free distal end and is configured to engage a guide hole in an object to align the object with the die set when crimping; and
a second die including a second body having a second face plate and at least one indentor extending from the second face plate, the at least one indentor being made of a hardened material that can withstand multiple impacts against objects being impacted, and having a free distal end, wherein the at least one indentor is aligned on the second face plate to engage one or more grooves on the object when crimping.

2. The die set according to claim 1 , wherein the guide member has a proximal end attached to the first face plate.

3. The die set according to claim 1 , wherein the guide member has a proximal end integrally formed into the first face plate.

4. The die set according to claim 1 , wherein the guide member is substantially perpendicular to the first face plate.

5. The die set according to claim 1 , wherein the first face plate and the second face plate are substantially flat.

6. The die set according to claim 1 , wherein the first body and the second body are substantially U-shaped.

7. The die set according to claim 1 , wherein the at least one indentor has a proximal end attached to the second face plate.

8. The die set according to claim 1 , wherein the at least one indentor has a proximal end integrally formed into the second face plate.

9. The die set according to claim 1 , wherein the at least one indentor is substantially perpendicular to the second face plate.

10. A connector and die set kit comprising:
an electrical connector comprising:
a body;
a first arm extending from the body;
a second arm extending from the body; and
a crimping channel between the first and second arms,
wherein the first arm has an inner surface with one or more grooves and a guide hole formed in an outer surface of the first arm; and
wherein the second arm has an inner surface with one or more detents extending into the crimping channel and one or more grooves on an outer surface of the second arm; and

a die set for power tools used to crimp the electrical connector, the die set comprising:
a first die including a first body having a first face plate and a guide member extending from the first face plate, the guide member having a free distal end, wherein the guide member is configured to engage the guide hole to align the electrical connector with the die set when crimping; and
a second die including a body having a second face plate and a plurality of indentors extending from the second face plate, each of the plurality of indentors having a free distal end, wherein the plurality of indentors are aligned to engage the one or more grooves on the outer surface of the second arm when crimping.

11. The connector and die set kit according to claim 10 , wherein the body, first arm and second arm of the electrical connector are made from an electrically conductive material.

12. The connector and die set kit according to claim 11 , wherein the electrically conductive material is copper.

13. The connector and die set kit according to claim 11 , wherein the electrically conductive material is aluminum.

14. The connector and die set kit according to claim 10 , wherein the guide member has a proximal end attached to the first face plate.

15. The connector and die set kit according to claim 10 , wherein the guide member has a proximal end integrally formed into the first face plate.

16. The connector and die set kit according to claim 10 , wherein the guide member is substantially perpendicular to the first face plate.

17. The connector and die set kit according to claim 10 , wherein the first face plate and the second face plate are substantially flat.

18. The connector and die set kit according to claim 10 , wherein the first body and the second body are substantially U-shaped.

19. The connector and die set kit according to claim 10 , wherein each of the plurality of indentors has a proximal end attached to the second face plate.

20. The connector and die set kit according to claim 10 , wherein each of the plurality of indentors has a proximal end integrally formed into the second face plate.

21. The connector and die set kit according to claim 10 , wherein each of the plurality of indentors is substantially perpendicular to the second face plate.

22. An electrical connector, die set and power tool kit comprising:
an electrical connector comprising:
a body;
a first arm extending from the body;
a second arm extending from the body; and
a crimping channel between the first and second arms,
wherein the first arm has an inner surface with one or more grooves and a guide hole formed in an outer surface of the first arm; and
wherein the second arm has an inner surface with one or more detents extending into the crimping channel and one or more grooves on an outer surface of the second arm; and

a die set for power tools used to crimp the electrical connector, the die set comprising:
a first die including a first body having a first face plate associated with the body and a guide member extending from the first face plate, the guide member having a free distal end, wherein the guide member is configured to engage the guide hole to align the electrical connector with the die set when crimping; and
a second die including a second body having a second face plate associated with the body and a plurality of indentors extending from the second face plate, each of the plurality of indentors having a free distal end, wherein the plurality of indentors are aligned to engage the one or more grooves on the outer surface of the second arm when crimping; and

a hand-held power tool having a movable ram nest to receive one of the first die or the second die and a fixed frame nest to receive one of the first die or the second die, such that when activated the power tool causes the movable ram nest to move towards the frame nest so that the electrical connector positioned between the first and second dies is crimped.
