Abstract

The invention relates to a connection between a first metal component and a second metal component covered by a sheath. The first and the second metal component are connected to one another by means of a welded connection. In each case, a partial region of the first metal component and a partial region of the second metal component that comprises at least one section of the sheath are enclosed by a layer of insulating material that is applied.

Claims

1. A device for connecting between a first metal component and a second metal component covered by a sheath, comprising:

a partial region of the first metal component and a partial region of the second metal component, involving at least a section of the sheath, being respectively covered by an applied insulating layer; and

a contact layer of nickel phosphorous (NiP) being applied to the first metal component, and the applied insulating layer being composed of polyorganosiloxane,

wherein the first and the second metal component are joined by a welded connection, and subjected to an insulated atmospheric plasma, and

wherein the insulating layer is insert-molded and is cross-linked by subjecting the insulating layer to heat.

2. The device of claim 1, wherein the first metal component is made of copper or a copper alloy.

3. The device of claim 1, wherein the sheath for the second metal component is composed of a polyorganosiloxane (HTV silicon).

4. The device of claim 1, wherein the polyorganosiloxane is a liquid silicon rubber (LSR).

5. The device of claim 1, wherein the first metal component is made of copper or a copper alloy.

6. The device of claim 5, wherein the second metal component is made of aluminum.

7. The device of claim 1, wherein the sheath for the second metal component is composed of a polyorganosiloxane.

8. The device of claim 7, wherein the polyorganosiloxane of the sheath for the second metal component is a high temperature vulcanization (HTV) silicon.

9. The device of claim 1, wherein the contact layer of NiP has a thickness of approximately 0.3 to 5 μ

m.

10. The device of claim 9, wherein the contact layer of NiP has a thickness of approximately 0.5 to 3 μ

m.

11. The device of claim 1, wherein the contact layer of NiP has a thickness of approximately 0.3 to 5 μ

m.

12. The device of claim 11, wherein the contact layer of NiP has a thickness of approximately 0.5 to 3 μ

m.

13. A method for producing a connection between a first metal component and a second metal component covered by a sheath, comprising:

covering the first metal component with a contact layer of nickel phosphorous (NiP);

connecting an end piece of the second metal component, with some sections of its sheath exposed and with an aid of a welded connection, to the first metal component;

cleaning a partial region of the cable sheath, that is to be insert-molded later on with an insulating material;

subjecting the connecting region, between the first and the second metal component, and the partial region of the cable sheath, to be insert-molded, to an insulated atmospheric plasma;

insert-molding the connecting region, and at least a partial region of the sheath around the cable, with an insulating material of a poly-organosiloxane; and

cross-linking the insulating material through heating.

14. The method of claim 13, further comprising cleaning the partial region of the cable sheath with at least one of cellulose and isopropanol.

15. The method of claim 13, wherein the polyorganosiloxane is a liquid silicon rubber (LSR).
