Abstract

An electrical device having at least one functional element that includes a ceramic body, on which a first electrical contact layer and a second electrical contact layer are applied to two opposite-lying side faces, respectively, and the functional element is arranged between a first contact strip and a second contact strip, wherein the first contact strip and the second contact strip comprise several contact pins, respectively, and wherein the first contact layer electrically contacts at least one contact pin of the first contact strip and the second contact layer electrically contacts at least one contact pin of the second contact strip.

First claim

The invention claimed is:

1. An electrical device comprising at least one functional element that comprises a ceramic body, on which a first electrical contact layer and a second electrical contact layer are applied to two opposite-lying side faces, respectively, said functional element is arranged between a first contact strip and a second contact strip, a cap arranged over the functional element and the contact strips, wherein 1) the first contact strip and the second contact strip comprise several contact pins, respectively, 2) the cap clamps the contact pins to the first and second contact layers, 3) the first contact layer electrically contacts at least one contact pin of the first contact strip and the second contact layer electrically contacts at least one contact pin of the second contact strip, 4) the functional element is clamped between the first contact strip and the second contact strip by the cap, 5) each of the contact strips comprises a support strip in which the contact pins are fastened, and 6) each contact pin comprises an elongated pin-shaped or rod-shaped body.

2. The device according to claim 1 , wherein the support strips comprise metal and/or plastic material.

3. The device according to claim 1 , wherein the contact pins of the contact strips protrude through the respective support strip in uniform spacings with respect to one another.

4. The device according to claim 1 , wherein the cap covers the functional element and support strips of the contact strips.

5. The device according to claim 1 , wherein the cap comprises inclined regions on two opposite-lying inner sides, in which regions the support strips are arranged.

6. The device according to claim 1 , comprising several functional elements arranged between the first contact strip and the second contact strip.

7. The device according to claim 6 , wherein at least two of the several functional elements are arranged next to one another along the contact strips.

8. The device according to claim 6 , wherein at least two of the several functional elements are arranged one on top of another along the contact pins.

9. The device according to claim 6 , wherein at least one of the several functional elements contacts precisely one contact pin of the first contact strip and one contact pin of the second contact strip.

10. The device according to claim 1 , further comprising at least one additional functional element and a third contact strip, wherein the at least one additional functional element is arranged between the second contact strip and the third contact strip.

11. The device according to claim 1 , wherein the at least one functional element is a capacitor element, the ceramic body comprises a layer stack having ceramic layers arranged one on top of another and first and second electrode layers arranged between said ceramic layers, and the electrode layers extend from the two opposite-lying side faces of the ceramic body into the layer stack.

12. The device according to claim 1 , wherein the functional element is a varistor element, a PTC thermistor element or an NTC thermistor element.

13. The device according to claim 2 , wherein the contact pins of the contact strips protrude through the respective support strip in uniform spacings with respect to one another.

14. The device according to claim 7 , wherein at least two of the several functional elements are arranged one on top of another along the contact pins.

15. The device according to claim 1 , wherein contact pins are mechanically prestressed and function in a spring-like manner.
