Abstract

A housing for a control device, in particular for a pneumatic control device, is disclosed. The housing comprises the following components: a housing wall, which forms a receiving space for receiving an electronic component of the control device and has at least one opening, and a flexible insulation element, which surrounds the at least one opening in such a way that the flexible insulation element, together with the housing wall, defines a sound insulation space, wherein the flexible insulation element comprises at least one element selected from the group consisting of a flexible film, a flexible textile fabric and a flexible foam layer.

First claim

The invention claimed is:

1. A housing for a pneumatic control device, comprising:
a housing wall defining a receiving space for receiving an electronic component of the pneumatic control device and having at least one opening; and
a flexible insulation element surrounding the at least one opening in such a way that the flexible insulation element, together with the housing wall, defines a sound insulation space, wherein the flexible insulation element comprises at least one element selected from the group consisting of a flexible film, a flexible textile fabric and a flexible foam layer,

wherein the flexible insulation element comprises an electrically conductive region configured to conduct electrostatic charges.

2. The housing as claimed in claim 1 , wherein the electrically conductive region is connected electrically to the electronic component.

3. The housing as claimed in claim 1 , wherein the flexible insulation element has a sufficient dielectric strength so that at least one electrostatic discharge, produced during an ESD test, does not break through the flexible insulation element.

4. The housing as claimed in claim 1 , wherein the housing wall is formed from an electrically nonconductive material.

5. The housing as claimed in any claim 1 , wherein the flexible insulation element is mounted on an inner side of the housing wall.

6. The housing as claimed in claim 1 , wherein the flexible insulation element is at least partially corrugated.

7. The housing as claimed in claim 1 , wherein the housing wall has, in a region of the flexible insulation element, projections which extend in a direction of the flexible insulation element and serve as a bearing surface for the flexible insulation element.

8. The housing as claimed in claim 1 , wherein the flexible insulation element is connected to the housing wall and at least partially protecting the electronic component situated in the receiving space from at least one of dust, drips and spray.

9. The housing as claimed in claim 1 , wherein the flexible insulation element is connected to the housing wall only in an edge region of the flexible insulation element.

10. The housing as claimed in claim 9 , wherein the flexible insulation element is connected to the housing wall in the edge region only in some but not all section or sections.

11. The housing as claimed in claim 1 , wherein the electronic component extends at least partially through the at least one opening, and
the flexible insulation element surrounds both the at least one opening and a section of the electronic component which projects from the at least one opening.

12. The housing as claimed in claim 1 , wherein the at least one opening comprises at least two openings, of which one of the at least two openings is arranged closer to the electronic component that is sensitive to electrostatic discharge than another of the at least two openings, and wherein the flexible insulation element surrounds only the opening which is arranged closer to the sensitive electronic component.

13. The pneumatic control device, comprising:
the housing as claimed in claim 1 ,
the electronic component, which is arranged in the receiving space of the housing.
