Abstract

The invention relates to an arrangement comprising a first electrical component, which has a pair of flat, spaced-apart first connection lugs, a second electrical component, which has a pair of flat, spaced-apart second connection lugs, wherein the first and second connection lugs are in each case connected in pairs in an electrically conductive manner, and an electrically conductive plate which is electrically insulated from the first and second connection lugs and which is arranged below the first and second connection lugs in the plane of the surfaces of the first and second connection lugs.

Claims

1. An arrangement (10), comprising:

a first electrical component (1), which has a pair of flat, spaced-apart first connection lugs (3a, 3b);

a second electrical component (2), which has a pair of flat, spaced-apart second connection lugs (4a, 4b), wherein the first and second connection lugs (3a, 3b;

4a, 4b) are connected in pairs in an electrically conductive manner; and

an electrically conductive plate (6) which is electrically insulated from the first and second connection lugs (3a, 3b;

4a, 4b) and which is arranged below the first and second connection lugs (3a, 3b;

4a, 4b) in a plane of surfaces of the first and second connection lugs (3a, 3b;

4a, 4b).

2. The arrangement (10) according to claim 1, further comprising:

an insulation layer (7) which is arranged between the first and second connection lugs (3a, 3b;

4a, 4b) and the electrically conductive plate (6).

3. The arrangement (10) according to claim 2, wherein the insulation layer (7) is adhesively bonded on the second connection lugs (4a, 4b), and the electrically conductive plate (6) is adhesively bonded on the insulation layer (7).

4. The arrangement (10) according to claim 2, wherein the insulation layer (7) constitutes a dielectric film which has a high dielectric constant and forms a low-inductance, capacitive path between the second connection lugs (4a, 4b).

5. The arrangment (10) according to claim 1, further comprising:

a multiplicity of electrically conductive elevated portions (8) which are disposed in a region below at least one of the first and second connection lugs (3a, 3b;

4a, 4b) on the electrically conductive plate (6).

6. The arrangement (10) according to claim 1, wherein the electrically conductive plate (6) is a cooling plate, which is disposed planarly parallel along a lateral surface of the first electrical component (1) and which is configured to dissipate waste heat from the first electrical component (1), said waste heat developing during operation of the first electrical component (1).

7. The arrangement (10) according to claim 1, wherein the first electrical component (1) is a film capacitor and the second electrical component (2) is an electrical bus bar.

8. The arrangement (10) according to claim 1, wherein the first connection lugs (3a, 3b) overlap in pairs with the second connection lugs (4a, 4b) and wherein the pairs of overlapped connection lugs are in each case spaced apart from each other at a minimum distance.

9. A method (20) for contacting electrical components (1;

2) comprising the following steps;

overlapping (21) in pairs of first flat connection lugs (3a;

3b) of a first electrical component (1) with second flat connection lugs (4a;

4b) of a second electrical component (2);

connecting (22) the pairs of first and second connection lugs (3a, 3b;

4a, 4b) in an electrically conductive manner; and

arranging (24) an electrically conductive plate (6) below the pairs of first and second connection lugs (3a, 3b;

4a, 4b), wherein the electrically conductive plate (6) is electrically insulated from the first and second connection lugs (3a, 3b;

4a, 4b).

10. The method (20) according to claim 9, further comprising the step:

arranging (23) an insulation layer (7) between the first and second connection lugs (3a, 3b;

4a, 4b) and the electrically conductive plate (6).

11. The method (20) according to claim 9, wherein the first electrical component (1) is a film capacitor and the second electrical component (2) is an electrical bus bar.
