Insulating element
View Patent ↗An insulating element insulates a contact area of an electronic component from other contact areas of the component. In order to ensure an assembly that is as trouble-free as possible as well as a trouble-free operation, the insulation element has at least on a first section, which is accommodated inside a contact recess of a contact during operation, is provided with an outer contour that enables an accommodation with the utmost smallest amount of play inside the contact recess.
1. An insulating element for electrically insulating a first contact region of an electronic component from at least one second contact region of the electronic component and/or from a contact making contact with the second contact region during operation, the contact having a contact recess formed therein and the electronic component having a further contact recess formed therein and the first contact region disposed in the further contact recess, the insulation element comprising:
at least one first section to be accommodated in the contact recess of the contact during operation, said first section having an outer contour approximately corresponding, at least in regions, to an inner contour of the contact recess of the contact such that, during operation, said first section being accommodated in the contact recess of the contact with at most a low degree of play; and
a second section disposed opposite said first section and configured such that said second section can be accommodated in the further contact recess during operation, said second section having an outer contour approximately corresponding, at least in regions, to an inner contour of the further contact recess such that, during operation, said second section being accommodated in the further contact recess with at most a low degree of play.
2. The insulating element according to claim 1 , wherein at least one of said first section and said second section has at least one mating region configured for making mechanical contact at least partly, during operation, in an event of said first section and, respectively, said second section being accommodated in the contact recess and the further contact recess, respectively with the inner contour thereof for forming a form-locking connection at least in regions.
3. The insulating element according to claim 2 , wherein said mating region is formed from at least one material selected from the group consisting of elastically deformable materials and plastically deformable materials.
4. The insulating element according to claim 2 , wherein in a region of said mating region, said outer contour of at least one of said first section and said second section, in a state not accommodated in the contact recess or the further contact recess, has, at least in regions, a larger diameter than the inner contour of the contact recess or the further contact recess, respectively.
5. The insulating element according to claim 1 , wherein said first section has an offset formed in a region of said outer contour, said offset having a larger diameter than said outer contour of said second section such that a shoulder is formed in a transition region toward said second section, and on said shoulder the insulating element is supported during operation on the electronic device.
6. The insulating element according to claim 1 , further comprising:
end regions, including a first end region and a second end region, at least one of said first section and said second section is disposed between said first and second end regions.
7. The insulating element according to claim 6 , wherein said end regions are formed as threading-in regions that run conically at least in regions and serve for assisting in self-centering insertion of at least one of said first section and said second section into the contact recess and the further contact recess, respectively.
8. The insulating element according to claim 1 , wherein said first section and said second section are formed as a one-piece unit from a material selected from the group consisting of ceramic materials and Al 2 O 3 .
9. The insulating element according to claim 1 , wherein said first section and said second section have a recess formed therein, and through said recess, during operation, a contact can be led to the first contact region while preserving an insulated state with other contacts.
10. The insulating element according to claim 1 , wherein the electronic component is a power semiconductor element.
11. The insulating element according to claim 2 , wherein said mating region is disposed at and defines part of said outer contour.
12. The insulating element according to claim 9 , wherein said recess of said first and second sections runs centrally therein.
