Abstract

A pane has an electrical connection element and connection cable including a substrate, an electrically conductive structure on a region of the substrate, wherein the connection cable has, on its lower face facing the substrate, a contact region, in which a conductor track of the connection cable is connected to the region of the electrically conductive structure, the connection element is rigid and has a first flat region for contacting the connection cable, the connection element with the conductor track of the connection cable on an upper face of the connection cable facing away from the substrate is electrically conductively connected to the connection cable via a weld region, the contact region of the connection cable and the first flat region of the connection element are arranged one above the other such that the flat region of the connection element is provided for transferring heat to the soldering compound.

First claim

The invention claimed is:

1. A pane having an electrical connection element and connection cable at least comprising:
a substrate,
an electrically conductive structure on a region of the substrate,
wherein
the connection cable has, on its lower face facing the substrate, a contact region, in which a conductor track of the connection cable is connected to a portion of the electrically conductive structure,
the connection element is rigid and has a first flat region for electrically contacting the connection cable,
the connection element with the conductor track of the connection cable on an upper face of the connection cable facing away from the substrate is electrically conductively connected to the connection cable via a weld region,
the contact region of the connection cable and the first flat region of the connection element are arranged one above the other such that the flat region of the connection element is provided for transferring heat to a soldering compound provided in the contact region that connects the conductor track of the connection cable to the portion of the electrically conductive structure.

2. The pane according to claim 1 , wherein the connection cable has a first section, a second section, and a fold, in which the first section and the second section are arranged one above the other.

3. The pane according to claim 1 , wherein the connection cable is flat and flexible and the conductor track contains at least one metal foil.

4. The pane according to claim 1 , wherein the connection element contains at least copper, a copper-containing alloy, or steel.

5. A method for producing a pane according to claim 1 , wherein
the connection element is connected, on an upper face of a connection cable, via a weld region to the connection cable,
a soldering compound is applied in a contact region on a lower face of the connection cable facing away from the upper face,
the connection cable with soldering compound is arranged on an electrically conductive structure on a substrate of the pane and is fixed on the substrate by means of an adhesive,
the connection cable is electrically conductively connected to the electrically conductive structure by means of the soldering compound under the introduction of heat.

6. The method according to claim 5 , wherein a first flat section of the connection element is heated such that the soldering compound is melted and the connection cable is soldered.

7. The method according to claim 5 , wherein a resistive or inductive soldering method or hot air is used.

8. A method comprising utilizing a pane according to claim 1 in buildings or in means of transportation for travel on land, in the air, or on water.

9. The method according to claim 8 , wherein the pane is in a motor vehicle or a rail vehicle.

10. The method according to claim 8 , wherein the pane is a windshield, a rear window, a side window, and/or roof panel.

11. The method according to claim 8 , wherein the pane is a heatable pane.

12. A pane having an electrical connection element and connection cable at least comprising:
a substrate,
an electrically conductive structure on a region of the substrate,
wherein
the connection cable has, on its lower face facing the substrate, a contact region, in which a conductor track of the connection cable is connected to a portion of the electrically conductive structure,
the connection element is rigid and has a first flat region for contacting the connection cable,
the connection element with the conductor track of the connection cable on an upper face of the connection cable facing away from the substrate is electrically conductively connected to the connection cable via a weld region,
the contact region of the connection cable and the first flat region of the connection element are arranged one above the other such that the flat region of the connection element is provided for transferring heat to a soldering compound provided in the contact region,
wherein the connection element has
a transition region and
a second flat region at its end facing away from the connection cable.

13. The pane according to claim 12 , wherein the transition region of the connection element has a length of at least 30% of the length of the connection element.

14. The pane according to claim 12 , wherein the connection element with the transition region has a pitch angle in the range of 30° to 90° relative to the connection cable.

15. The pane according to claim 12 , wherein the second flat region is configured to contact a voltage source.

16. The pane according to claim 12 , wherein the second flat region has a plug or a cable.

17. A pane having an electrical connection element and connection cable at least comprising:
a substrate,
an electrically conductive structure on a region of the substrate,
wherein
the connection cable has, on its lower face facing the substrate, a contact region, in which a conductor track of the connection cable is connected to a portion of the electrically conductive structure,
the connection element is rigid and has a first flat region for contacting the connection cable,
the connection element with the conductor track of the connection cable on an upper face of the connection cable facing away from the substrate is electrically conductively connected to the connection cable via a weld region,
the contact region of the connection cable and the first flat region of the connection element are arranged one above the other such that the flat region of the connection element is provided for transferring heat to a soldering compound provided in the contact region,
wherein the connection element is formed in one piece.
