Abstract

A shielding spring shell has a contact tab with a pair of spring sections adjoining a fillet. One of the spring sections is an at least radially resilient radial spring and another of the spring sections is an at least axially resilient axial spring.

First claim

What is claimed is:

1. A shielding spring shell, comprising:
a shell body; and
a contact tab extending from the shell body and including a pair of spring sections adjoining a fillet, one of the spring sections is an at least radially resilient radial spring and another of the spring sections is an at least axially resilient axial spring located on an external portion of the shell body.

2. The shielding spring shell of claim 1 , wherein the radial spring has a contact surface pointing in a radial direction.

3. The shielding spring shell of claim 2 , wherein the axial spring has a contact surface pointing in an axial direction.

4. The shielding spring shell of claim 3 , wherein the contact surface of the axial spring is formed on a bulge of the contact tab.

5. The shielding spring shell of claim 1 , wherein an angle of the fillet between the radial spring and the axial spring is at most about 90.

6. The shielding spring shell of claim 1 , wherein the shell body extends along a longitudinal axis.

7. The shielding spring shell of claim 6 , wherein the contact tab extends away from an end of the shell body.

8. The shielding spring shell of claim 7 , wherein the contact tab is arranged at each of a pair of opposite ends of the shell body.

9. The shielding spring shell of claim 7 , wherein a plurality of contact tabs are arranged in a crown-like manner at the end of the shell body.

10. The shielding spring shell of claim 1 , wherein the shielding spring shell is formed integrally as a monolithic component.

11. A connector, comprising:
a base body extending along a longitudinal axis;
a collar projecting radially relative to the base body;
a receptacle defined by a gap between the collar and the base body;
and
a shielding spring shell inserted into the receptacle, the shielding spring shell has a contact tab with a pair of spring sections adjoining a fillet, one of the spring sections is an at least radially resilient radial spring and another of the spring sections is an at least axially resilient axial spring, the contact tab protrudes from the receptacle.

12. The connector of claim 11 , wherein the contact tab is bent back at an end around a wall of the receptacle.

13. The connector of claim 11 , wherein a flat side of the collar has a notch extending in a radial direction.

14. The connector of claim 13 , wherein the axial spring is inserted into the notch.

15. The connector of claim 11 , wherein the shielding spring shell has a pair of contact tabs spaced from one another in a circumferential direction.

16. The connector of claim 15 , further comprising a rib arranged in a slot between the pair of contact tabs.

17. The connector of claim 11 , wherein the collar and the base body are formed integrally as a monolithic housing.

18. A connector assembly, comprising:
a connector including a base body extending along a longitudinal axis, a receptacle defined at least in part by the base body, and a shielding spring shell inserted into the receptacle, the shielding spring shell has a contact tab with a pair of spring sections adjoining a fillet, one of the spring sections is an at least radially resilient radial spring and another of the spring sections is an at least axially resilient axial spring, the contact tab protrudes from the receptacle; and
a mating connector plugged together with the connector, the axial spring is supported in an axial direction on the mating connector.

19. The connector assembly of claim 18 , wherein the mating connector is one of a pair of mating connectors plugged at different ends of the connector.

20. The connector assembly of claim 19 , wherein the shielding spring shell has at least one contact tab at each of a pair of opposite ends, the axial spring of each of the contact tabs is supported in the axial direction on one of the mating connectors.
