Stack height tolerance compensating busbar structure
An electrical connector assembly is disclosed, the assembly having an electrical connector and a plurality of contacts coupled to a plurality of fixed bodies by plurality of fasteners adapted to facilitate relative movement of the electrical connector and the contacts relative to the fixed bodies while maintain an electrical communication.
1. An electrical connector assembly comprising:
an electrical connector formed from an electrically conductive material;
a contact disposed between and abutting said electrical connector and a fixed body, said contact adapted to provide electrical engagement between said electrical connector and the fixed body; and
a fastener adapted to couple said electrical connector and said contact to the fixed body, wherein said electrical connector rotates about said fastener in response to changes in height of the fixed body.
2. The electrical connector according to claim 1 , wherein said electrical connector is an elongate member having a substantially rectangular cross-sectional shape.
3. The electrical connector according to claim 1 , wherein said contact is a cam.
4. The electrical connector according to claim 3 , wherein said contact includes louvers.
5. The electrical connector according to claim 4 , wherein said contact and the louvers are formed from a first material and the louvers are coated with a second material.
6. The electrical connector according to claim 5 , wherein said contact is formed from a first material and the louvers are formed from a second material.
7. The electrical connector according to claim 6 , wherein the first material is a steel and the second material is copper.
8. The electrical connector according to claim 1 , further comprising a second contact disposed between and abutting said electrical connector and the fixed body.
9. The electrical connector according to claim 1 , wherein said electrical connector is formed from one of copper, aluminum, nickel, and a combination thereof.
10. The electrical connector according to claim 1 , wherein said electrical connector is produced by stamping sheet metal.
11. The electrical connector according to claim 1 , wherein said fastener is a bolt and a nut.
12. The electrical connector according to claim 1 , wherein the nut of said fastener is a self-clinching nut.
13. The electrical connector according to claim 1 , wherein the fixed body is one of a collector plate and a main contact of a fuel cell stack.
14. An electrical connector assembly comprising:
an electrical connector formed from an electrically conductive material;
a first contact disposed between and abutting said electrical connector and a first fixed body, said first contact adapted to provide electrical engagement between said electrical connector and the first fixed body;
a second contact disposed between and abutting said electrical connector and a second fixed body, said second contact adapted to provide electrical engagement between said electrical connector and the second fixed body; and
a plurality of fasteners adapted to couple said electrical connector and said first contact to the first fixed body and adapted to couple said electrical connector and said second contact, wherein said electrical connector rotates about said fasteners in response to changes in height of the first fixed body and the second fixed body.
15. The electrical connector according to claim 14 , wherein said first and second contacts are cams.
16. The electrical connector according to claim 15 , wherein said first and second contacts include louvers.
17. The electrical connector according to claim 14 , wherein said fastener is a bolt and a self-clinching nut.
18. The electrical connector according to claim 14 , wherein the first fixed body is a collector plate and the second fixed body is a main contact of a fuel cell stack.
