Abstract

An add-on housing is provided comprising a frame-shaped basic shape which encloses a receiving region for receiving a contact insert or a holding frame fitted with plug-in connector modules, wherein at least two fastening surfaces having fastening openings are integrally formed on the outside of the frame-shaped basic shape, wherein the add-on housing has snap-fastening means or devices which engage through the fastening openings in order to mechanically fasten the add-on housing to a through-hole in a device wall. A method for fastening an add-on housing to a through-hole in a device wall is also provided, wherein: the add-on housing has fastening openings which are in alignment with corresponding fastening openings in the device wall; snap-fastening means or devices having a box-shaped main body and having opposing and resiliently mounted base portions laterally protruding from said main body are inserted into the mutually aligned fastening openings in the add-on housing and the device wall; the base portions, upon insertion into the fastening openings, are first pressed into the box-shaped main body and then extend to engage the device wall.

First claim

The invention claimed is:

1. An add-on housing having a frame-like basic shape which surrounds a receiving region for receiving a contact insert or a retention frame which is provided with plug-type connector modules,
wherein at least two fastening faces having fastening openings are formed on the frame-like basic shape,
wherein the add-on housing has snap-fastening devices which, in order to mechanically fasten the add-on housing to a wall aperture of a device wall, engage through the fastening openings, and
wherein each of the snap-fastening devices has a case-like base member, and wherein resiliently supported base portions protrude from mutually opposing narrow faces of the case-like base member to engage the device wall.

2. The add-on housing as claimed in claim 1 , wherein the fastening faces are formed on narrow sides of the add-on housing.

3. The add-on housing as claimed in claim 1 , wherein the fastening openings are constructed in a rectangular manner.

4. The add-on housing as claimed in claim 1 , wherein the fastening openings each have a circumferential seal.

5. The add-on housing as claimed in claim 1 , wherein each of the snap-fastening devices has a mechanism which is accessible via an outwardly directed face thereof and by way of which the base portions can be guided in the case-like base member.

6. An add-on housing having a frame-like basic shape which surrounds a receiving region for receiving a contact insert or a retention frame which is provided with plug-type connector modules,
wherein at least two fastening faces having fastening openings are formed on the frame-like basic shape,
wherein the add-on housing has snap-fastening devices which, in order to mechanically fasten the add-on housing to a wall aperture of a device wall, engage through the fastening openings,
wherein each of the snap-fastening devices has base portions that are configured to engage the device wall, and
wherein the base portions each have a first inclined face and a second inclined face, and wherein the second inclined face is configured to engage the device wall.

7. The add-on housing as claimed in claim 6 , wherein the second inclined face is oriented at an acute angle with respect to the device wall.

8. A method for fastening an add-on housing to a wall aperture of a device wall, wherein the add-on housing has fastening openings which are in alignment with corresponding fastening openings in the device wall, the method comprising:
introducing snap-fastening devices in the mutually aligned fastening openings of the add-on housing and the device wall, each of the snap-fastening devices having a case-like base member and laterally protruding, mutually opposing and resiliently supported base portions,
wherein, during introduction of the snap-fastening devices into the mutually aligned fastening openings, the base portions are initially pressed into the case-like base member and then subsequently extend to engage the device wall, and
wherein the base portions each have a first inclined face and a second inclined face, and wherein, during introduction of the snap-fastening devices into the mutually aligned fastening openings, the first inclined face initially slides along an edge of a respective one of the fastening openings and the second inclined face subsequently engages the device wall.
