Abstract

Claims (18)

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.
