Abstract

A spring contact for a coaxial connector includes a first ring provided with a plurality of spring fingers extending toward a connector end of the first ring and a second ring provided with a plurality of spring fingers extending toward a connector end of the second ring. The first ring and the second ring are nested together. The spring contact may be manufactured, for example, by stamping a pre-form ring from a planar metal sheet and then bending the spring fingers extending radially inward from an inner diameter of the pre-form ring to extend towards a connector end of the resulting spring contact.

Claims (25)

1. A spring contact for a coaxial connector having a connector end and cable end, the spring contact comprising:

a first ring provided with a plurality of first spring fingers extending toward a connector end of the first ring; and

a second ring provided with a plurality of second spring fingers extending toward a connector end of the second ring;

the cable end of the first ring stacks adjacent the connector end of the second ring such that the first spring fingers of the first ring alternate with the second spring fingers of the second ring resulting in a single interleaved generally cylindrical surface.

2. The spring contact of claim 1 , wherein a gap between the first and second spring fingers and a finger width of the first and second spring fingers are generally equal to one another.

3. The spring contact of claim 1 , wherein a cable end of the first ring abuts the connector end of the second ring.

4. The spring contact of claim 1 , wherein the first and second spring fingers of each have a taper proximate a distal end.

5. The spring contact of claim 1 , wherein the first and second spring fingers are angled radially inward in a first portion and are angled radially outward in a second portion.

6. The spring contact of claim 1 , wherein the first and second spring fingers extend from an inner diameter of the first and second rings, respectively.

7. The spring contact of claim 6 , wherein the distal end of the first and second spring fingers are dimensioned to contact a connector body bore of the coaxial connector.

8. The spring contact of claim 1 , further including a protrusion extending radially outward from the first ring and the second ring.

9. The spring contact of claim 8 , wherein the protrusion is a plurality of protrusions, each protrusion proximate a circumferential position of a spring finger.

10. A method for manufacturing a spring contact for a coaxial connector having a connector end and cable end, comprising the steps of:

providing a first ring with a plurality of first spring fingers extending toward a connector end of the first ring;

providing a second ring provided with a plurality of second spring fingers extending toward a connector end of the second ring; and

stacking the cable end of the first ring and the connector end of the second ring adjacent one another such that the first spring fingers of the first ring alternate with the second spring fingers of the second ring resulting in a single interleaved generally cylindrical surface.

11. The method of claim 10 , wherein the first ring and the second ring are stamped from a planar material and the first and second spring fingers are bent to extend toward the connector end of the first ring and the second ring.

12. The method of claim 10 , wherein the first ring and the second ring are non-ferrous metal.

13. The method of claim 10 , wherein the first ring and the second ring are non-magnetic metal.

14. The method of claim 10 , wherein the spring fingers extend from an inner diameter of the first ring and the second ring.

15. The method of claim 10 , wherein the spring fingers of the second ring are longer than the spring fingers of the first ring, by a thickness of the first ring.

16. The method of claim 10 , wherein the spring fingers are provided with a connector body bore contact portion coplanar with a connector body bore of the coaxial connector.

17. The method of claim 10 , wherein the first and second spring fingers are angled radially inward in a first portion and are angled radially outward in a second portion.

18. The method of claim 10 , wherein the first ring and the second ring are phosphor bronze alloy.

19. The method of claim 18 , wherein the first ring and the second ring are tin plated.
