Abstract

A pane having an electrical connection element, the pane having: a substrate; an electrically conductive structure in a region of the substrate; and a connection element in a region of the electrically conductive structure, the connection element containing at least a chromium-containing steel. The connection element has a region which is crimped about a connecting cable and a soldering region connected to the electrically conductive structure by means of a lead-free solder.

First claim

The invention claimed is:

1. A pane with at least one electrical connection element, comprising:
a substrate;
on a region of the substrate, an electrically conductive structure; and
on a region of the electrically conductive structure, a connection element that comprises at least a chromium-containing steel,
wherein the connection element has, at a distal end of the connection element, a region crimped around a connection cable, and a solder region that is connected to the electrically conductive structure via a leadfree solder material, and
wherein the connection element comprises at least 66.5 wt.-% to 89.5 wt.-% iron, 10.5 wt.-% to 20 wt.-% chromium, 0 wt.-% to 1 wt.-% carbon, 0 wt.-% to 5 wt.-% nickel, 0 wt.-% to 2 wt.-% manganese, 0 wt.-% to 2.5 wt.-% molybdenum, 0 wt.-% to 2 wt.-% niobium, and 0 wt.-% to 1 wt.-% titanium.

2. The pane according to claim 1 , wherein an angle between the solder region and the crimped region is from 120° to 180°.

3. The pane according to claim 1 , which includes two to six connection elements disposed in a line.

4. The pane according to claim 1 , wherein a material thickness of the connection element is from 0.1 mm to 2 mm.

5. The pane according to claim 1 , wherein a difference between a coefficient of thermal expansion of the substrate and the coefficient of thermal expansion of the connection element is less than 5×10 −6 /° C.

6. The pane according to claim 1 , wherein the connection element comprises at least 77 wt.-% to 84 wt.-% iron, 16 wt.-% to 18.5 wt.-% chromium, 0 wt.-% to 0.1 wt.-% carbon, 0 wt.-% to 1 wt.-% manganese, 0 wt.-% to 1 wt.-% niobium, 0 wt.-% to 1.5 wt.-% molybdenum, and 0 wt.-% to 1 wt.-% titanium.

7. The pane according to claim 1 , wherein the substrate contains glass.

8. The pane according to claim 1 , wherein the electrically conductive structure contains at least silver and has a layer thickness of 5 μm to 40 μm.

9. The pane according to claim 1 , wherein a layer thickness of the solder material is less than or equal to 6.0×10 −4 m.

10. The pane according to claim 1 , wherein the solder material contains tin and bismuth, indium, zinc, copper, silver, or compositions thereof.

11. The pane according to claim 10 , wherein the solder material contains 35 wt.-% to 69 wt.-% bismuth, 30 wt.-% to 50 wt.-% tin, 1 wt.-% to 10 wt.-% silver, and 0 wt.-% to 5 wt.-% copper.

12. The pane according to claim 1 , wherein the connection element has at least a wetting layer that contains nickel, tin, copper, and/or silver.

13. A method for production of the pane with at least one electrical connection element, comprising:
connecting a connection element to a connection cable by crimping in a region at a distal end of the connection element;
applying a solder material on a bottom of a solder region of the connection element;
disposing the connection element with the solder material on a region of an electrically conductive structure that is applied on a region of a substrate; and
connecting the connection element, with energy input, to the electrically conductive structure.

14. A method comprising:
applying the pane with at least one electrical connection element according to claim 1 , in buildings or in means of transportation for travel on land, in the air, or on water.

15. The pane according to claim 2 , wherein the angle between the solder region and the crimped region is from 150° to 170°.

16. The pane according to claim 3 , wherein a distance between adjacent connection elements is from 5 mm to 50 mm.

17. The pane according to claim 3 , wherein a distance between adjacent connection elements is from 10 mm to 20 mm.

18. The pane according to claim 4 , wherein a material thickness of the connection element is from 0.2 mm to 1 mm.

19. The pane according to claim 4 , wherein a material thickness of the connection element is from 0.3 mm to 0.5 mm.

20. The pane according to claim 7 , wherein the glass comprises: float glass, quartz glass, borosilicate glass, and/or soda lime glass.

21. The pane according to claim 8 , wherein the at least silver comprises silver particles and glass frits.

22. The method according to claim 14 , comprising:
applying the pane with at least one electrical connection element according to claim 1 as a windshield, rear window, side window, and/or glass roof.

23. The method according to claim 14 , comprising:
applying the pane with at least one electrical connection element according to claim 1 as a heatable pane or as a pane with an antenna function.
