Abstract

An electrical connector having a housing and a plurality of electrical contacts. The housing has contact receiving areas with a general uniform cross-like shape. The electrical contacts are one-piece serpentine shaped spring contacts connected to the housing in the receiving areas. A center section of the contact has mounting wings that are located in lateral apertures of the cross-like shape to fixedly mount the contacts to the housing. Opposite ends of the contacts extend out of the receiving areas for contacting contact pads on parallel printed circuit boards on opposite sides of the connector.

Claims

1. An electrical connector comprising:

a housing having a plurality of contact receiving areas; and

a plurality of one-piece serpentine shaped spring contacts connected to the housing in the receiving areas, the contacts each having two reversely oriented spring arms connected by a center section that combine to form the serpentine shape, ends of the spring arms of each contact extending out of opposite open ends of one of the receiving areas and, the center section having transversely extending mounting wings that extend out of a plane of the serpentine shape and connect the contact to the housing.

2. A connector as in claim 1 wherein the contact receiving areas extend through the housing between a first side and a second side with a uniform general cross-like shape.

3. A connector as in claim 2 wherein the contact receiving areas each have a center aperture and two lateral apertures extending from opposite sides of the center aperture to form the general cross-like shape.

4. A connector as in claim 3 wherein the mounting wings are located in the lateral apertures and the rest of the contacts are located in the center apertures and extending out of the center apertures at the first and second sides.

5. A connector as in claim 1 wherein the contacts are comprised of cut and stamped flat sheet metal.

6. An electrical connector comprising:

a housing having a plurality of contact receiving areas extending through the housing from a first side to a second side, the receiving areas having a uniform general cross-like shape from the first side to the second side; and

a plurality of electrical contacts connected to the housing in the receiving areas, the contacts being comprised of cut and stamped flat sheet metal, each contact having a pair of spring arms with lateral mounting wings, the pair of spring arms extending out of the receiving areas at the first and second sides and the lateral mounting wings fixedly mounting each contact to the housing.

7. A connector as in claim 6 wherein the receiving areas each have a center apertures and two lateral apertures extending from opposite sides of the center aperture to form the general cross-like shape.

8. A connector as in claim 7 wherein the lateral mounting wings are located in the lateral apertures.

9. A connector as in claim 6 wherein the contacts have a general serpentine shape.

10. A connector as in claim 6 wherein the contact is about 0.05 inch between opposite ends of the spring arms and the spring arms are about 0.01 inch wide.

11. A connector as in claim 10 wherein the contacts are about 0.003 inch thick and the mounting wings are about 0.026 inch wide.
