Abstract

Power connector including a pair of discrete contact springs configured to electrically engage a conductive component. Each of the contact springs includes a contact body having opposite inner and outer side surfaces and a contact edge that extends between the inner and outer side surfaces. The contact body is shaped to form a spring base and a mating portion. The spring bases of the contact springs are joined by a locking feature. The locking feature includes a localized portion of at least one of the spring bases. The localized portion frictionally engages the other spring base to interlock the spring bases. Each of the mating portions extends from the corresponding spring base. The mating portions are separated by a receiving space and are configured to engage the conductive component when the conductive component is inserted into the receiving space.

First claim

What is claimed is:

1. A power connector comprising:
a pair of discrete contact springs configured to electrically engage a conductive component, each of the contact springs comprising a contact body having opposite inner and outer side surfaces and a contact edge that extends between the inner and outer side surfaces, the contact body being shaped to form a spring base and a mating portion;
wherein the spring bases of the contact springs are joined by a locking feature, the locking feature including a localized portion of at least one of the spring bases, the localized portion frictionally engaging the other spring base to interlock the spring bases;
wherein each of the mating portions extends from the corresponding spring base, the mating portions being separated by a receiving space and configured to engage the conductive component when the conductive component is inserted into the receiving space.

2. The power connector of claim 1 , wherein the locking feature includes a plurality of locking features that join the spring bases, wherein at least two of the locking features are proximate to a base seam formed by the spring bases, the mating portions extending from the base seam.

3. The power connector of claim 1 , wherein the pair of contact springs include first and second contact springs, the first contact spring including a body projection formed from the localized portion, the spring base of the second contact spring including a body recess, the body projection extending into the body recess and directly engaging the spring base of the second contact spring to interlock the spring bases.

4. The power connector of claim 3 , wherein the body projection frictionally engages a surface that defines the body recess.

5. The power connector of claim 4 , wherein the body recess has a recess opening along the inner side surface of the second contact spring, the body projection having a distal punch profile, the punch profile being greater than the recess opening to prevent removal of the body projection.

6. The power connector of claim 3 , wherein the body recess is a window, the body projection extending through the window and directly engaging the outer side surface of the second contact spring.

7. The power connector of claim 1 , wherein the contact springs include first and second contact springs, the locking feature being a co-punched feature in which the spring base of the first contact spring is punched into the spring base of the second contact spring to form the locking feature.

8. The power connector of claim 1 , wherein the contact springs are shaped from corresponding contact blanks, the contact blanks being stamped from sheet metal and having identical profiles.

9. The power connector of claim 1 , wherein each of the mating portions includes a plurality of contact fingers, the contact fingers configured to engage and be deflected by the conductive component.

10. The power connector of claim 1 , wherein the contact springs also include respective mounting portions that are configured to couple to a power supply.

11. The power connector of claim 1 , wherein the power connector is a busbar connector configured to engage a busbar in the receiving space and each of the contact springs is configured to transmit at least 200 A.

12. The power connector of claim 1 , wherein the contact springs are directly joined without fastening hardware and without melting of the contact springs.

13. A power connector comprising:
discrete first and second contact springs configured to electrically engage a conductive component, each of the first and second contact springs comprising a contact body having opposite inner and outer side surfaces and a contact edge that extends between the inner and outer side surfaces, wherein the inner side surfaces of the first and second contact springs are positioned side-by-side along an interface;
wherein the first and second contact springs are joined by a plurality of co-punched locking features, each of the locking features including a localized portion of one of the first and second contact springs that is stamped into, and thereby deforms, a localized portion of the other of the first and second contact springs.

14. The power connector of claim 13 , wherein each of the first and second contact springs is shaped to include a mating portion and a spring base, the mating portions opposing each other with a receiving space therebetween, the spring bases being joined by the locking features.

15. The power connector of claim 14 , wherein each of the mating portions includes a plurality of contact fingers, the contact fingers configured to engage and be deflected by the conductive component.

16. The power connector of claim 13 , wherein the localized portions of the locking features do not include the contact edge.

17. The power connector of claim 13 , wherein the first and second contact springs are shaped from corresponding contact blanks, the contact blanks being stamped from sheet metal and having identical profiles.

18. The power connector of claim 13 , wherein the contact springs include respective mounting portions that are configured to couple to a power supply.

19. The power connector of claim 13 , wherein the power connector is a busbar connector configured to engage a busbar and each of the contact springs is configured to transmit at least 200 A.

20. The power connector of claim 13 , wherein the contact springs are directly joined without separate hardware and without melting of the contact springs.
