Abstract

A pressing element is configured for an electrical component which needs to be pressed against another element for contact. The electrical component includes at least one electrically conductive touch contact. The pressing element has an annular pressing surface for the electrical component. An outer contour of the pressing surface is greater than an outer contour of the electrical component which needs to be pressed. The pressing surface has an annular elevation which forms a bearing surface for the electrical component.

First claim

The invention claimed is:

1. An electrical/electronic component comprising,
a housing;
at least one electrical structural element, including at least one electrically conductive touch contact, and
a pressing element associated with a side of the at least one electrical structural element averted from the at least one electrically conductive touch contact, the pressing element held in the housing so as to be prestressed against the at least one electrical structural element,
wherein:
the pressing element includes an annular pressing surface configured to contact the at least one electrical structural element,
an outer contour of the annular pressing surface is larger than an outer contour of the at least one electrical structural element, and
the annular pressing surface has an annular raised portion configured as a bearing surface for the at least one electrical structural element;
the housing has at least two housing parts;
the at least one electrical structural element is held in a prestressed manner between the at least two housing parts via interposition of the pressing element; and
one of the at least two housing parts includes a mating touch contact against which the at least one electrical structural element is pushed by way of the at least one electrically conductive touch contact by the pressing element.

2. The component as claimed in claim 1 , wherein the pressing element has an annular configuration.

3. The component as claimed in claim 2 , wherein the annular pressing surface extends from a casing inner wall to a casing outer wall of the pressing element.

4. The component as claimed in claim 3 , wherein the casing inner wall extends axially as far as the bearing surface to form the annular raised portion.

5. The component as claimed in claim 3 , wherein the casing inner wall is oriented obliquely with respect to at least one of the bearing surface and the annular pressing surface.

6. The component as claimed in claim 3 , wherein the casing inner wall is oriented obliquely such that a clear width of the pressing element decreases starting from the bearing surface.

7. The component as claimed in claim 1 , wherein the pressing element is manufactured from one of silicone and a thermoplastic elastomer.

8. The component as claimed in claim 1 , wherein the component is a sensor component.

9. The component as claimed in claim 1 , wherein the at least one electrical structural element is a sensor element.

10. An electrical/electronic component comprising,
a housing;
at least one electrical structural element, including at least one electrically conductive touch contact, and
a pressing element associated with a side of the at least one electrical structural element averted from the at least one electrically conductive touch contact, the pressing element held in the housing so as to be prestressed against the at least one electrical structural element,
wherein:
the pressing element includes an annular pressing surface configured to contact the at least one electrical structural element,
an outer contour of the annular pressing surface is larger than an outer contour of the at least one electrical structural element, and
the annular pressing surface has an annular raised portion configured as a bearing surface for the at least one electrical structural element;
the at least one electrical structural element is a sensor element.

11. The component as claimed in claim 10 , wherein the pressing element has an annular configuration.

12. The component as claimed in claim 11 , wherein the annular pressing surface extends from a casing inner wall to a casing outer wall of the pressing element.

13. The component as claimed in claim 12 , wherein the casing inner wall extends axially as far as the bearing surface to form the annular raised portion.

14. The component as claimed in claim 12 , wherein the casing inner wall is oriented obliquely with respect to at least one of the bearing surface and the annular pressing surface.

15. The component as claimed in claim 12 , wherein the casing inner wall is oriented obliquely such that a clear width of the pressing element decreases starting from the bearing surface.

16. The component as claimed in claim 10 , wherein the pressing element is manufactured from one of silicone and a thermoplastic elastomer.

17. The component as claimed in claim 10 , wherein:
the housing has at least two housing parts, and
the at least one electrical structural element is held in a prestressed manner between the at least two housing parts via interposition of the pressing element.

18. An electrical/electronic component comprising,
a housing that includes a mating touch contact;
at least one electrical structural element, including at least one electrically conductive touch contact, and
a pressing element associated with a side of the at least one electrical structural element averted from the at least one electrically conductive touch contact, the pressing element held in the housing so as to be prestressed against the at least one electrical structural element,
wherein:
the pressing element includes an annular pressing surface configured to contact the at least one electrical structural element,
an outer contour of the annular pressing surface is larger than an outer contour of the at least one electrical structural element,
the annular pressing surface has an annular raised portion configured as a bearing surface for the at least one electrical structural element; and
the pressing element is configured such that the prestress of the pressing element causes the pressing element to push the at least one electrically conductive touch contact of the at least one electrical structural element into electrical contact with the mating touch contact of the housing.
