Abstract

A component for the production of a laminated sheet, includes at least two electrical functional elements and cabling, which includes electrical conductors having insulating sheathing and connected in each case to an electrical functional element, wherein the cabling has a bundling section, in which all the electrical conductors are surrounded by a common insulating sheathing.

First claim

The invention claimed is:

1. A laminated sheet, comprising:
a first pane and a second pane that are connected together via a thermoplastic film arranged between the first and the second pane, and
a component that comprises at least two electrical functional elements and cabling, which comprises electrical conductors having insulating sheathing and connected in each case to an electrical functional element,
wherein the cabling has a bundling section, in which all the electrical conductors are surrounded by common insulating sheathing,
wherein at least one of the at least two electrical functional elements is arranged between the thermoplastic film and one of the first and second panes, and
wherein the bundling section of the cabling is arranged outside the laminated sheet.

2. The laminated sheet according to claim 1 , wherein the component further comprises at least one external electrical functional element for external attachment to the laminated sheet.

3. The laminated sheet according to claim 1 , wherein the cabling includes, for each electrical functional element, an associated individual section, which is connected to the respective electrical functional element and in which the electrical conductor(s) of said functional element are surrounded by their own insulating sheathing, which surrounds no electrical conductor(s) of the other functional element(s).

4. The laminated sheet according to claim 3 , wherein the component comprises at least three electrical functional elements, wherein the individual section of a functional element is connected to the bundling section and a partial bundling section, in which the electrical conductors of the other functional elements are surrounded by common insulating sheathing.

5. The laminated sheet according to claim 3 , wherein the component further comprises at least one external electrical functional element for external attachment to the laminated sheet and wherein the external electrical functional element and/or the individual section of the external electrical functional element is provided with an adhesive.

6. The laminated sheet according to claim 1 , wherein ends of the conductors facing away from the functional elements are connected to at least one plug connector.

7. The laminated sheet according to claim 1 , wherein the electrical functional elements are implemented as sensors, transmitters, or electrical shielding elements.

8. The laminated sheet according to claim 1 , wherein the electrical conductors are implemented at least partially as flat conductors.

9. The laminated sheet according to claim 1 , wherein the cabling also includes electrical shields for decoupling the electrical conductors of various functional elements.

10. The laminated sheet according to claim 6 , wherein ends of the conductors facing away from the functional elements are connected to a single common plug connector.

11. The laminated sheet according to claim 7 , wherein the electrical functional elements are implemented as rain sensors, light sensors, relative humidity sensors, temperature sensors, switch surfaces, light emitting diodes, image sensors, antennas, displays, heating elements, ultrasonic sensors, or electrical shielding elements.
