Abstract

A bus bar contact (10) for mounting on a circuit board having a U-shaped section, contact fingers (20), mounting tabs (26), and termination posts (30,32) extending therefrom. Guide means, which comprises a guide slot (44) in the circuit board or guide tabs (52) on the contact, is provided to protect the contact fingers from damage due to improper insertion. Securing means, which comprises mounting holes or bent portions of the solder tabs, is provided to secure the contact to the circuit board.

Claims

1. A bus bar contact for mounting on a circuit board, comprising:

a U-shaped center section having ends and a front and a back, the U-shaped center section being defined by parallel legs and a curved section, the top of the contact being defined by the curved section;

contact fingers extending from the front of the U-shaped section, said fingers having contact sections for electrical connection with a matable contact, the ends of the U-shaped center section being disposed below the contact fingers;

termination posts extending from the ends of said U-shaped section to be received in holes in the circuit board to be soldered thereto and provide electrical connection therewith;

stabilization tabs extending from the ends of said U-shaped section, the tabs being disposed below the contact fingers to provide stability and support for the contact against the circuit board;

securing means for securing said contact on the circuit board;

guide means for guiding the matable contact into electrical contact with said contact fingers and to prevent damage to the contact fingers.

2. The bus bar contact of claim 1, wherein said securing means is a hole disposed on said tab to secure the contact to the circuit board.

3. The bus bar contact of claim 2, wherein said termination posts extend from the ends of said U-shaped section, the termination posts extending in generally the same direction as legs on the U-shaped section, and said tabs extend perpendicular to said termination posts.

4. The bus bar contact of claim 3, wherein said contact fingers extend from both sides of said U-shaped section, said contact fingers being arranged in an alternating fashion from the U-shaped section, wherein contact fingers on one of the sides is staggered from the contact fingers on another of the sides.

5. The bus bar contact of claim 4, wherein said contact fingers have curved portions and camming surfaces, and a matable contact receiving channel therebetween, the contact fingers are cammed apart when the matable contact is inserted and are resiliently biased thereagainst.

6. The bus bar contact of claim 2, wherein said guide means comprises integral guide tabs extending forwardly from said mounting tabs and being disposed below said contact fingers, thereby defining a guide slot between said guide tabs and is centrally located below said contact fingers to guide a matable contact into electrical connection with said contact fingers and to protect said contact fingers from damage due to improper insertion of the matable contact.

7. The bus bar contact of claim 6, wherein said U-shaped section includes parallel legs, the parallel legs have lances which secure the parallel legs together and strengthen the U-shaped section.

8. The bus bar contact of claim 7, wherein said termination posts extend from the ends of said U-shaped section, the termination posts extending in generally the same direction as legs on the U-shaped section, and said mounting tabs extend perpendicular to said termination posts.

9. The bus bar contact of claim 8, wherein said contact fingers extend from both sides of said U-shaped section, said contact fingers being arranged in an alternating fashion from the U-shaped section, wherein contact fingers on one of the sides is staggered from the contact fingers on another of the sides.

10. The bus bar contact of claim 9, wherein said contact fingers have curved portions and camming surfaces, and a matable contact receiving channel therebetween, the contact fingers are cammed apart when the matable contact is inserted and are resiliently biased thereagainst.

11. The bus bar contact of claim 1, wherein termination posts are solder tabs and said securing means comprises a bent portion of said solder tab, said bent portion engages holes on the circuit board to secure the contact thereto.

12. The bus bar contact of claim 11, wherein said tabs are stabilization tabs and are disposed about the U-shaped section in a staggered orientation to provide greater stability to the contact, one of the tabs being closer to the contact fingers than another of the tabs.

13. The bus bar contact of claim 11, wherein said solder tabs extend from the ends of said U-shaped section, the termination posts extending in generally the same direction as legs on the U-shaped section, and said mounting tabs extend perpendicular to said solder tabs.

14. The bus bar contact of claim 13, wherein said solder tabs comprise a straight section and a securing section with a slit therebetween, said securing section comprises said bent portion.

15. The bus bar contact of claim 14, wherein said solder tabs are disposed in a staggered orientation about the U-shaped portion to provide greater stability.

16. The bus bar contact of claim 15, wherein said contact fingers extend from both sides of said U-shaped section, said contact fingers being arranged in an alternating fashion from the U-shaped section, wherein contact fingers on one of the sides is staggered from the contact fingers on another of the sides.

17. The bus bar contact of claim 16, wherein said contact fingers have curved portions and camming surfaces, and a matable contact receiving channel therebetween, the contact fingers are cammed apart when the matable contact is inserted and are resiliently biased thereagainst.
