Abstract

A filter component includes a housing body. A first and at least one second busbar each have a first end section, and a second end section, between which in each case a center section is arranged. The end sections of the busbars each have connections for connecting electrical conductors to the filter component. The first and second end section and the center section of the first busbar are arranged in a first plane and the first and second end section and the center section of the at least one second busbar are arranged in a second plane, which is different from the first plane.

Claims

a second busbar having a first end section and a second end section, and a center section between the first end section and the second end section,

wherein the first busbar has a first connection for connecting to a first potential and a second connection for connecting to a first load,

wherein the second busbar has a first connection for connecting to a second potential, which is different from the first potential, and a second connection for connecting to a second load, which is different from the first load, or for connecting to a reference potential,

wherein the first connection of the first busbar is arranged in the first end section of the first busbar and the second connection of the first busbar is arranged in the second end section of the first busbar,

wherein the first connection of the second busbar is arranged in the first end section of the second busbar and the second connection of the second busbar is arranged in the second end section of the second busbar,

wherein the first end section of the first busbar projects out of the housing body on a first side of the housing body, the second end section of the first busbar projects out of the housing body on a second side of the housing body, and the center section of the first busbar is arranged in the housing body, the second side being different than the first side,

wherein the first end section of the second busbar projects out of the housing body on the first side of the housing body, the second end section of the second busbar projects out of the housing body on the second side of the housing body, and the center section of the second busbar is arranged in the housing body,

wherein the first end section, the second end section and the center section of the first busbar are arranged in a first plane,

wherein the first end section, the second end section and the center section of the second busbar are arranged in a second plane, which is different than the first plane,

wherein the first end sections of the first and second busbars are located with respect to one another such that the first connection of the first busbar and the first connection of the second busbar are not oriented so as to align with one another, and

wherein the second end sections of the first and second busbars are located with respect to one another such that the second connection of the first busbar and the second connection of the second busbar are not oriented so as to align with one another.

2. The filter component according to claim 1, wherein the first and second busbars are each designed as a flat conductor.

3. The filter component according to claim 2,

wherein the first connection of the first busbar is designed as a depression in the first end section of the first busbar,

wherein the first connection of the second busbar is designed as a depression in the first end section of the second busbar,

wherein the second connection of the first busbar is designed as a depression in the second end section of the first busbar, and

wherein the second connection of the second busbar is designed as a depression in the second end section of the second busbar.

4. The filter component according to claim 1,

wherein the first connection of the first busbar comprises a first fastening device for fastening the first end section of the first busbar to a first electrical conductor that provides the first potential,

wherein the second connection of the first busbar comprises a second fastening device for fastening the second end section of the first busbar to a second electrical conductor for coupling the second end section of the first busbar to the first load,

wherein the first connection of the second busbar comprises a third fastening device for fastening the first end section of the second busbar to a third electrical conductor that provides the second potential, and

wherein the second connection of the second busbar comprises a fourth fastening device for fastening the second end section of the second busbar to a fourth electrical conductor for coupling the second end section of the second busbar to the second load or to the reference potential.

5. The filter component according to claim 4, wherein at least one of the first and second connections of the first and second busbars comprises a screw thread.

6. The filter component according to claim 1, further comprising a magnetic core arranged in the housing body surrounding the center sections of the first and second busbars.

7. The filter component according to claim 6,

wherein the first busbar is designed such that at least one of the first and second end sections and the center section thereof are insertable into the magnetic core, and

wherein the second busbar is designed such that at least one of the first and second end sections and the center section thereof are insertable into the magnetic core.

8. The filter component according to claim 6, wherein at least one of the first and the second busbars has a plurality of electrical conductors that are arranged in the housing body in a stack arrangement and are surrounded by the magnetic core.
