Abstract

An electric component has a housing part and a component support which is provided with a conductor path structure. The conductor path structure has an interruption, by which a connection section of the conductor path structure is galvanically separated from a main section of the conductor path structure. The component support is arranged on the housing part such that a heat-conductive connection is produced between the component support and the housing part. The main section remains galvanically separated from the housing part. The electric resistance between the main section of the conductor path structure and the housing part is measured. The component support is secured to the housing part by a securing element. The interruption is electrically bridged by the securing element and the main section is electrically conductively connected to the housing component.

First claim

The invention claimed is:

1. An electronic component, comprising:
a housing part formed with a supporting surface and an annular gap disposed adjacent said supporting surface;
a component support having a first main side, a second main side opposite said first main side, and a conductor path structure;
said component support being disposed with said second main side on said supporting surface of said housing part and connected to said housing part via at least one securing element;
said conductor path structure having, in a region of said securing element, an interruption, by way of which a connection section of said conductor path structure is galvanically separated from a main section of said conductor path structure;
a plurality of electronic components arranged on said first main side of said component support and electrically connected to one another by way of said main section of said conductor path structure; and
a heat-conductive, insulating layer arranged in sections between said component support and said housing part in order to remove heat from said component support via said housing part, said heat-conductive, insulating layer disposed in said annular gap of said housing part;
wherein said connection section is electrically conductively connected to said housing part;
when said securing element secures said component support on said housing part, said securing element bridges said interruption electrically and produces an electrically conductive connection between said main section of said conductor path structure, which main section is otherwise galvanically separated from the housing part, and said housing part by way of the electric bridging of the interruption between said connection section and said main section by said securing element.

2. The component according to claim 1 , wherein said connection portion of said conductor path structure has, in the region of said securing element, a first contact surface which is formed on said first main side and a second contact surface which is formed on said second main side and lies opposite said first contact surface.

3. The component according to claim 2 , wherein said second contact surface rests on said housing part.

4. The component according to claim 2 , wherein said first and second contact surfaces are electrically conductively connected through said component support by way of a section of said conductor path structure of said component support.

5. The component according to claim 2 , wherein said housing part has, in the region of said securing element to be provided, a third contact surface in electric contact with said second contact surface when said component support is arranged in said housing part.

6. The component according to claim 2 , wherein at least said first contact surface is provided with an electrically conductive, plastically deformable layer.

7. The component according to claim 1 , wherein said securing element is an element selected from the group consisting of a screw, a rivet, a grooved drive stud and a clamping element which engages through a recess or bore of said component support into a corresponding engagement opening in said housing part when said securing element secures said component support on said housing part.

8. The component according to claim 7 , wherein said interruption of said conductor path structure is formed around said recess or said bore.

9. The component according to claim 7 , wherein said conductor path structure is formed to follow a shape of said recess or bore.

10. The component according to claim 1 , wherein said securing element is composed of an electrically conductive material.

11. The component according to claim 1 , wherein said securing element is formed with a conductive layer at least in a section that faces said interruption.

12. The component according to claim 1 , wherein said securing element has a cutting ring in a region of a supporting surface bordering said first main side.
