Abstract

A splice connector assembly configured to conduct more than 1 kilowatt of electricity includes a terminal having a connection portion configured to interconnect with a corresponding mating terminal. The terminal also has an attachment portion. The attachment portion has a planar shape. The attachment portion is attached to a first wire electrical cable and is also attached to a second wire electrical cable. The first cable has a different cross-sectional area than the second cable. The splice connector assembly also includes a dielectric housing defining a cavity in which the terminal is disposed.

First claim

We claim:

1. A high power splice connector assembly configured to conduct more than 1 kilowatt of electricity, comprising:
a terminal having a connection portion configured to conduct a first current and to interconnect with a corresponding mating terminal and having an attachment portion, wherein the attachment portion has a planar shape, wherein the attachment portion is attached to a first wire electrical cable configured to conduct a second current and is also attached to a second wire electrical cable configured to conduct a third current, and wherein the first cable has a different cross-sectional area than the second cable; and
a dielectric housing defining a cavity in which the terminal is disposed.

2. The high power splice connector of claim 1 , wherein a first cross-sectional area of the first cable is at least 25 square millimeters and a second cross-sectional area of the second cable is greater than first cross-sectional area.

3. The high power splice connector of claim 1 , wherein the first and second cables are welded to the attachment portion.

4. The high power splice connector of claim 3 , wherein the first and second cables are sonically welded to the attachment portion.

5. The high power splice connector of claim 1 , further comprising a terminal position assurance device defining a lance configured to contact the attachment portion of the terminal, thereby securing the terminal within the cavity.

6. The high power splice connector of claim 5 , wherein the lance is formed of a dielectric material and wherein the lance is positioned between the first and second cables, thereby electrically insulating first cable from the second cable.

7. The high power splice connector of claim 1 , wherein the terminal is a first terminal having a first connection portion and a first attachment portion and the cavity is a first cavity, wherein the assembly further comprises a second terminal having a second connection portion and having a planar second attachment portion, wherein the second attachment portion is attached to a third wire electrical cable and is also attached to a fourth wire electrical cable, wherein the third cable has a different cross-sectional area than the second cable, and wherein the housing defines a second cavity in which the second terminal is disposed.

8. The high power splice connector of claim 7 , wherein the second terminal is rotated 180 degrees relative to the first terminal.

9. The high power splice connector of claim 7 , wherein the first cable has the same cross-sectional area as the third cable and the second cable has the same cross-sectional area as the fourth cable.

10. A method of assembling a high power splice connector assembly configured to conduct more than 1 kilowatt of electricity, comprising:
providing a terminal having a connection portion configured to conduct a first current and to interconnect with a corresponding mating terminal and having an attachment portion, wherein the attachment portion has a planar shape;
attaching a first wire electrical cable configured to conduct a second current to the attachment portion;
attaching a second wire electrical cable configured to conduct a third current to the attachment portion, wherein the first cable has a different cross-sectional area than the second cable; and
inserting the terminal within a cavity defined by a dielectric housing.

11. The method of claim 10 , wherein a first cross-sectional area of the first cable is at least 25 square millimeters and a second cross-sectional area of the second cable is greater than first cross-sectional area.

12. The method of claim 10 , further comprising welding the first and second cables to the attachment portion.

13. The method of claim 12 , further comprising sonically welding the first and second cables to the attachment portion.

14. The method of claim 10 , further comprising inserting a terminal position assurance device defining a lance within the cavity until the lance contacts the attachment portion of the terminal, thereby securing the terminal within the cavity.

15. The method of claim 14 , wherein the lance is formed of a dielectric material.

16. The method of claim 15 , further comprising positioning the lance between the first and second cables, thereby electrically insulating first cable from the second cable.

17. The method of claim 10 , wherein the terminal is a first terminal having a first connection portion and a first attachment portion and the cavity is a first cavity and wherein the method further comprises:
providing a second terminal having a second connection portion and having a second attachment portion, wherein the second attachment portion has a planar shape;
attaching a third wire electrical cable to the second attachment portion;
attaching a fourth wire electrical cable to the second attachment portion, wherein the third cable has a different cross-sectional area than the fourth cable; and
inserting the second terminal within the second cavity.

18. The method of claim 17 , wherein the second terminal is rotated 180 degrees relative to the first terminal prior to insertion within the second cavity.

19. The method of claim 17 , wherein the first cable has the same cross-sectional area as the third cable and the second cable has the same cross-sectional area as the fourth cable.

20. A high power splice connector assembly configured to conduct more than 1 kilowatt of electricity, comprising:
a terminal configured to conduct a first current having means for attaching the terminal to a first wire electrical cable configured to conduct a second current and a second wire electrical cable configured to conduct a third current, wherein a first cross-sectional area of the first cable is at least 25 square millimeters and a second cross-sectional area of the second cable is greater than first cross-sectional area; and
a dielectric housing defining a cavity in which the terminal is disposed.
