Abstract

The invention relates to a power breaker for switching electrical loads having a parallelepipedal shape having four longitudinal sides lying in the longitudinal direction (LQ) of the parallelepiped, a first transverse side and an opposing second transverse side, an electromagnetic coil having a longitudinal axis (LS), an input connection, an output connection, and a moving contact path that is electrically connected to the input connection or the output connection. The invention also relates to power supply assembly arrangement for switching an electrical current between an external power supply line and at least one load where the moving contact path and the coil are arranged longitudinally parallel to one another in the longitudinal direction (LQ) of the parallelepipedal shape.

Claims

1. A power supply assembly for an electrical device comprising:

at least one power breaker comprising;

a parallelepipedal shape having four longitudinal sides lying in the longitudinal direction (LQ) of said parallelepipedal shape, a first transverse side and an opposing second transverse side,

an electromagnetic coil having a longitudinal axis (LS),

an input connection,

an output connection,

a moving contact path, which is electrically connected to one of said input connection and said output connection,

wherein said moving contact path and said coil are arranged longitudinally parallel to one another in the longitudinal direction (LQ) of said parallelepipedal shape; and

at least one terminal block having an input connection and an output connection, wherein said terminal block has said parallelepipedal shape of said power breaker and said input connection and said output connection are directly electrically connected to one another,

wherein said power breaker switches an electrical current between an external power supply line and at least one load, said external power supply line being electrically connected to said input connection of said at least one power breaker and said load being electrically connected to said output connection of said at least one power breaker.

2. A power supply assembly according to claim 1, wherein said parallelepipedal shape of said at least one power breaker further comprises a housing.

3. A power supply assembly according to claim 1, wherein said coil and said moving contact path are arranged longitudinally parallel one on top of the other.

4. A power supply assembly according to claim 1, wherein said input connection and said output connection of said at least one power breaker are arranged on opposing sides of said parallelepipedal shape of said at least one power breaker.

5. A power supply assembly according to claim 1, wherein said input connection of said at least one power breaker is arranged on said first transverse side of said at least one power breaker.

6. A power supply assembly according to claim 1, wherein said output connection of said at least one power breaker is arranged on said second transverse side of said at least one power breaker.

7. A power supply assembly according to claim 1, wherein said at least one power breaker is arranged on a printed circuit board.

8. A power supply assembly according to claim 7, wherein said at least one power breaker further comprises an insulating link, which acts as at least one of a carrier and a mount for said moving contact path, and which holds said moving contact path at a distance from said printed circuit board.

9. A power supply assembly according to claim 8, wherein said insulating link is fixed to said printed circuit board.

10. A power supply assembly according to claim 7, wherein contact is made with said coil via conductor tracks arranged on said printed circuit board.

11. A power supply assembly according to claim 7, wherein a broad side of said moving contact path is aligned essentially parallel to said printed circuit board.

12. A power supply assembly according to claim 1, wherein said moving contact path has a length (L9), which approximately corresponds to a length (L2) of said parallelepipedal shape of said power breaker, between a mount and a contact.

13. A power supply assembly according to claim 1, wherein said coil is part of an approximately parallelepipedal electromagnet, which is arranged upright and actuates said moving contact path in the manner of a contact lug with the interconnection of an actuating lever and a plunger.

14. A power supply assembly according to claim 1, wherein said output connection of said at least one power breaker, said input connection of said at least one power breaker and said moving contact path are in the form of a stamped, bent part, with said moving contact path being arranged integral to one of said output connection and said input connection.

15. A power supply assembly according to claim 1, wherein said input connection of said at least one terminal block, said output connection of said at least one terminal block and an electrical connection (EV) are formed as an integral stamped, bent part.
