Abstract

A spring contact component for a plug socket of an electromedical implant, with a coil surrounding the outer periphery of a plug opening. A simpler, more cost effective and automatable design of a plug socket module can be achieved in that at least one end of the coil is electrically and mechanically connected directly to a connector pin via a wire-shaped and/or strip-shaped element. The invention also relates to a corresponding plug socket module, a modular header, and a method for producing a spring contact component of this type.

First claim

We claim:

1. A spring contact component for a plug contact socket of an electromedical implant, the spring contact component comprising:
a coil surrounding an outer periphery of a plug opening, said coil having a first end and a second end, wherein the second end of the coil and a wire-shaped and/or strip-shaped element and also a connector pin are formed in one piece,
wherein the wire-shaped and/or strip-shaped element has a dimensionally stabilizing means surrounding the coil outwardly in the region of the periphery of said coil, said dimensionally stabilizing means being formed as a single or multiple ring or as a spiral.

2. The spring contact component as claimed in claim 1 , wherein the dimensionally stabilizing means is connected at a number of points to the coil.

3. The spring contact component as claimed in claim 1 , wherein the first end of the coil forms a connector pin.

4. A contact socket component for an electromedical implant comprising a spring contact component as claimed in claim 1 .

5. The contact socket component as claimed in claim 4 , wherein the spring contact component is inserted or embedded in a housing made of a non-conductive material and fabricated by means of injection molding, wherein a first connector pin and a second connector pin protrude from the housing in the region of the outer periphery.

6. A terminal housing for an electromedical implant comprising at least two contact socket components as claimed in claim 4 arranged side by side.

7. A spring contact component for a plug contact socket of an electromedical implant, the spring contact component comprising:
a coil surrounding an outer periphery of a plug opening, said coil having a first end and a second end, wherein the second end of the coil is electrically and mechanically connected directly to a connector pin via a wire-shaped and/or strip-shaped element,
wherein the wire-shaped and/or strip-shaped element has a dimensionally stabilizing means surrounding the coil outwardly in the region of the periphery of said coil, said dimensionally stabilizing means being formed as a single or multiple ring or as a spiral.

8. The spring contact component as claimed in claim 7 , wherein the coil and the wire-shaped and/or strip-shaped element are fabricated from the same electrically conductive material.

9. The spring contact component as claimed in claim 7 , wherein the dimensionally stabilizing means is connected at a number of points to the coil.

10. The spring contact component as claimed in claim 7 , wherein the first end of the coil forms a connector pin.

11. A method for producing a spring contact component for a plug contact socket of an electromedical implant with a coil surrounding the outer periphery of a continuous contacting opening, said method comprising the steps of:
producing a first coil and a second coil from a wire or a strip, wherein the first coil has a smaller diameter than the second coil;
forming an open torus from the first coil having the smaller diameter;
connecting, where appropriate, the first coil and the second coil together at one end of each coil; and
screwing the first coil in the form of an open torus into the second coil in such a way that the second coil forms a single or multiple ring or spiral outwardly surrounding the first coil in the region of the periphery of said first coil.

12. The method as claimed in claim 11 , wherein the first coil is canted before the torus is formed.

13. The method as claimed in claim 11 , wherein the ring, once screwed in, is fastened at a number of points of the first coil, preferably by means of laser welding or by electrically conductive self-curing plastics or adhesives.

14. A spring contact component for a plug contact socket of an electromedical implant, the spring contact component comprising:
a coil surrounding an outer periphery of a plug opening, said coil having a first end and a second end, wherein the second end of the coil and a wire-shaped and/or strip-shaped element and also a connector pin are formed in one piece,
wherein the coil is a torus spring and the wire-shaped and/or strip-shaped element is a single or multiple ring or a spiral outwardly surrounding the torus spring in the region of the periphery of said torus spring.

15. A spring contact component for a plug contact socket of an electromedical implant, the spring contact component comprising:
a coil surrounding an outer periphery of a plug opening, said coil having a first end and a second end, wherein the second end of the coil is electrically and mechanically connected directly to a connector pin via a wire-shaped and/or strip-shaped element,
wherein the coil is a torus spring and the wire-shaped and/or strip-shaped element is a single or multiple ring or a spiral outwardly surrounding the torus spring in the region of the periphery of said torus spring.
