Abstract

A power distributor of an electrical system of a motor vehicle, including a circuit board, which has a main connection to a main circuit and multiple secondary connections. Each secondary connection is assigned to one secondary circuit and electrically contacted with the main connection via a respective circuit breaker that has two connections. The two connections of each circuit breaker are electrically contacted directly with the circuit board.

First claim

What is claimed is:

1. A power distributor of an electrical system of a motor vehicle, the power distributor comprising:
circuit breakers; and
a circuit board that has a main connection to a main circuit and at least two secondary connections, each of the at least two secondary connections being assigned to one secondary circuit and electrically contacted with the main connection via a respective one of the circuit breakers,
wherein each of the circuit breakers include two connections extending therefrom that are electrically contacted directly with the circuit board and joined thereto, and
wherein each of the two connections of each of the circuit breakers is slit on a free end side to form two tongues, the two tongues of each of the two connections being spread apart.

2. The power distributor according to claim 1 , wherein at least one of the circuit breakers is a mechanical circuit breaker.

3. The power distributor according to claim 1 , wherein the circuit board is arranged in a housing closed via a removable cover.

4. The power distributor according to claim 1 , wherein each of the two connections of each of the circuit breakers is inserted through a corresponding hole in the circuit board and soldered there.

5. The power distributor according to claim 1 , wherein the two connections of each of the circuit breakers are soldered directly to the circuit board.

6. The power distributor according to claim 5 , wherein each of the two connections of each of the circuit breakers rests flat against the circuit board on a free end side and is soldered there.

7. The power distributor according to claim 1 , wherein each of the circuit breakers includes a circuit breaker housing, out of which the two connections project, the two connections being designed such that the circuit breaker housing rests against the circuit board over a wide area.

8. The power distributor according to claim 1 , wherein at least one of the circuit breakers is a thermal circuit breaker.

9. The power distributor according to claim 1 , wherein the main connection and the at least two secondary connections are each formed as solder pads or terminals or connectors.

10. The power distributor according to claim 1 , wherein a first one of the two connections of each of the circuit breakers is connected to the main connection and a second one of the two connections of each of the circuit breakers is connected to a respective one of the at least two secondary connections.

11. A circuit breaker of a power distributor, the circuit breaker comprising:
two connections extending therefrom that are electrically contacted directly with a circuit board and joined thereto,
wherein each of the two connections of the circuit breaker is slit on a free end side to form two tongues, the two tongues of each of the two connections being spread apart.

12. The circuit breaker according to claim 11 , wherein a first one of the two connections is connected to a main connection provided on the circuit board and a second one of the two connections is connected to a secondary connection provided on the circuit board.
