Abstract

A high current switch, in particular for a motor vehicle, having a first bus bar, a second bus bar in addition to a first semi-conductor switch that has a control connection and a first transmission connection as well as a second transmission connection. The first transmission connection is placed in direct contact with the first bus bar and the second transmission connection is placed in direct electric contact with the second bus bar.

First claim

What is claimed is:

1. A high current switch of a motor vehicle, comprising:
a first bus bar;
a second bus bar; and
a first semiconductor switch with a control connection and a first transmission connection and a second transmission connection, the first transmission connection being directly electrically contacted with the first bus bar and the second transmission connection being directly electrically contacted with the second bus bar,
wherein the first bus bar is arranged parallel to the second bus bar, such that a first face of the first bus bar opposes a first face of the second bus bar,
wherein the first semiconductor switch is arranged between the first bus bar and the second bus bar,
wherein an end face of the first transmission connection opposes the first face of the first bus bar and an end face of the second transmission connection opposes the first face of the second bus bar, and
wherein the end face of the first transmission connection directly electrically contacts the first face of the first bus bar and the end face of the second transmission connection directly electrically contacts the first face of the second bus bar.

2. The high current switch according to claim 1 , further comprising a second semiconductor switch that is connected in parallel to the first semiconductor switch.

3. The high current switch according to claim 1 , wherein each bus bar is formed by a cuboid stamped and bent part that has a width greater than 1 mm, a height greater than 1 mm and a length greater than 10 mm.

4. The high current switch according to claim 1 , wherein, each bus bar is formed by a plate-shaped stamped and bent part.

5. The high current switch according to claim 1 , wherein the first semiconductor switch is attached to the first bus bar and to the second bus bar.

6. The high current switch according to claim 1 , wherein the control connection is fixed to a printed circuit board and electrically contacted therewith.

7. The high current switch according to claim 6 , wherein the first bus bar has a contact point with which the first transmission connection is in direct mechanical contact and which is arranged in a first recess of the printed circuit board.

8. The high current switch according to claim 7 , wherein the contact point is flush with the printed circuit board.

9. The high current switch according to claim 6 , wherein the printed circuit board is oriented perpendicular to the first bus bar and the second bus bar.

10. The high current switch according to claim 6 , wherein the first bus bar and the second bus bar are fixed on the printed circuit board via beads.

11. The high current switch according to claim 1 , wherein the control connection is directly electrically contacted with an electrical line.
