Abstract

In a solder connection element (1), which is intended in particular for soldering onto a brittle substrate such as a window pane, for connecting an electrical component, which solder connection element has a body (2) provided for connecting purposes and at least two solder feet (3) protruding therefrom, a respective elastically deformable connecting part which is suitable for accommodating differences in thermal expansion extending between the body and the solder feet, more than two solder feet (3) are provided according to the invention for soldering onto a surface, wherein differences in thermal expansion and effects of mechanical forces from the component to be connected can be accommodated in at least two coordinate directions parallel to the substrate surface by way of resilience of the solder feet (3) and/or the connecting parts relative to the body (2) and/or the solder connection element (1). The body (2) itself can also be configured so as to be resilient by way of incisions (6) and/or equipped with a plug-in lug (5).

Claims

1. A solder connection element soldered on a window pane for connection of an electrical component comprising:

a body;

at least two resilient solder feet, wherein the at least two resilient solder feet protrude from the body; and

the resilient solder feet being adapted to accommodate differences in thermal expansion extending between the body and a surface of the window pane to which the solder connection element is connected, and further being adapted to accommodate effects of mechanical forces between the electrical component and the window pane in at least two coordinate directions parallel to the window pane, wherein;

the at least two resilient solder feet each comprise a solder surface and a solder foot, the solder surface connecting the body to the solder foot, the solder foot adapted to be soldered on the window pane, the solder foot having a lateral dimension larger than a lateral dimension of the solder surface and laying entirely in a single plane, and

the body comprises triangular incisions, wherein the incisions lay on a plane parallel to the window pane and are adapted to allow uniform compensation of longitudinal stresses in the body.

2. The solder connection element soldered on a window pane of claim 1,

wherein the incisions in the body form a plug-in lug for attaching a plug connector.

3. The solder connection element soldered on a window pane of claim 1, wherein the body comprises portions, wherein the portions are deformable for compensating for stresses acting between the at least two resilient solder feet.

4. The solder connection element soldered on a window pane of claim 1, wherein the body comprises a flexible line portion including a plug in contact.

5. The solder connection element soldered on a window pane of claim 1, wherein the body contains a feature selected from the group consisting of a weld, a solder surface, an adhesive surface, a plug-in lug, a plug-in socket, a push-button, and combinations thereof.

6. The solder connection element soldered on a window pane of claim 1, wherein the body, and the at least two resilient solder feet are configured in one piece or a plurality of pieces.

7. The solder connection element soldered on a window pane of claim 1, wherein the solder connection element is connected to at least one fixedly attached flexible conductor portion, wherein the at least one fixedly attached flexible conductor portion contains a plug part at its free end.

8. The solder connection element soldered on a window pane of claim 1, wherein the body is sheathed in its circumference which does not serve as a connection surface with an insulating material.

9. The solder connection element soldered on a window pane of claim 1, wherein the at least two resilient solder feet are arranged at mutually identical or different distances.

10. The solder connection element soldered on a window pane of claim 1, wherein the at least two resilient solder feet contain solder surfaces, wherein the solder surfaces are attached at their body-remote ends or folded down therefrom.

11. The solder connection element soldered on a window pane according to claim 1, wherein the window pane contains glass, polymers or layers or mixtures thereof.

12. The solder connection element soldered on a window pane substrate according to claim 1, wherein the window pane contains a polymer, the polymer containing polycarbonate, polymethyl methacrylate or blends thereof.

13. The solder connection element soldered on a window pane according to claim 1, wherein the window pane is single glazing or double glazing.

14. The solder connection element soldered on a window pane of claim 1, wherein the solder connection element is adapted to accommodate voltages from approximately 12 to 14 volts of DC voltage.

15. The solder connection element soldered on a window pane of claim 1, wherein the solder connection element is adapted to accommodate a current flow of more than 200 amperes.

16. The solder connection element soldered on a window pane of claim 1, wherein the at least two resilient solder feet have a thickness of between 0.01 mm and 0.4 mm.

17. The solder connection element soldered on a window pane of claim 1, wherein the at least two resilient solder feet protrude in a direction substantially normal to the body.

18. The solder connection element soldered on a window pane of claim 1, wherein the at least two resilient solder feet comprise more than two resilient solder feet protruding from opposing sides of the body.

19. The solder connection element soldered on a window pane of claim 1, wherein the at least two resilient solder feet are further adapted to accommodate effects of mechanical forces perpendicularly to the substrate window pane.

20. The solder connection element soldered on a window pane of claim 1, wherein the incisions in the body are arranged on opposite edges of the body.

21. The solder connection element soldered on a window pane of claim 1, wherein the solder connection element is in the form of a spherically arched one-piece sheet metal portion.
