Abstract

A module for producing a housing, in particular a housing of the ‘flameproof enclosure’ protection type, is provided, wherein the housing surrounds an interior space suitable for accommodating components that can form ignition sources. The module establishes at least one module interior space, which is fluidically connected to the interior space of the housing via a connection opening. The module can be used to produce vented housings having different interior volumes.

First claim

The invention claimed is:

1. A module for forming a portion of a housing, the housing surrounding an interior space of the housing suitable for accommodating components that can form ignition sources, the module establishing at least one module interior space, which is fluidically connected to the interior space of the housing through a connection opening.

2. The module according to claim 1 , wherein the module comprises a base element, which holds at least one wall element that delimits the at least one module interior space.

3. The module according to claim 1 , wherein the module is one of a plurality of modules, wherein when the plurality of modules are arranged in succession to form a channel made of fluidically contiguous interior spaces of the plurality of modules.

4. The module according to claim 3 , wherein port openings of each of the fluidically contiguous interior spaces of the plurality of modules are aligned with one another.

5. The module according to claim 4 , wherein the port openings abut one another.

6. The module according to claim 1 , wherein the connection opening is closed by a gas-permeable pressure relief body.

7. The module according to claim 6 , wherein the gas-permeable pressure relief body closes the connection opening in a flameproof manner.

8. A housing comprising a module according to claim 1 , wherein the housing includes a venting opening, which fluidically connects the at least one module interior space to a surrounding area of the housing.

9. The housing according to claim 8 , wherein a port opening of the at least one module interior space is directed at the venting opening of the housing or forms the venting opening.

10. A method for producing a housing according to claim 1 .

11. The module according to claim 2 , wherein the module is one of a plurality of modules, wherein when the plurality of modules are arranged in succession to form a channel made of fluidically contiguous interior spaces of the plurality of modules.

12. The module according to claim 2 , wherein the connection opening is closed by a gas-permeable pressure relief body.

13. The module according to claim 3 , wherein the connection opening is closed by a gas-permeable pressure relief body.

14. The module according to claim 4 , wherein the connection opening is closed by a gas-permeable pressure relief body.

15. The module according to claim 5 , wherein the connection opening is closed by a gas-permeable pressure relief body.

16. The module according to claim 11 , wherein the connection opening is closed by a gas-permeable pressure relief body.

17. A The module according to claim 16 , wherein the gas-permeable pressure relief body closes the connection opening in a flameproof manner.
