The object of the invention is to generate a compact and easy-to-install mounting housing. The task is characterized by the characterizing features of

independent claim 1 solved.

Advantageous embodiments of the invention are specified in the subclaims.

The attachment housing according to the invention is intended for this purpose

Provide connector in the range of a breakthrough of a cabinet or a device wall. However, the invention is not limited to this use.

The cultivation housing according to the invention has a frame-shaped

Basic shape, wherein the aperture opening of the cabinet or the device wall is disposed within the frame-shaped basic shape. Within the frame-shaped basic shape, the mounting housing fastening means for attaching the attachment housing to the

Wall opening on. In general, the fastening means are arranged in the vicinity of the edge region of the aperture opening.

Preferably, the mounting housing is equipped with a seal which is arranged between the mounting housing and the device wall. Since the fastening means within the frame-shaped basic shape must be provided here, no additional sealing means must be provided to protect the mounting housing from environmental influences.

The attachment housing has at least one clamping element, which is captively clamped within the frame-shaped basic shape. The clamping element is held or fixed by means of a clamping action within the frame-shaped basic shape. For this is no

Tool needed. The required technical clamping means are included on the clamping element and will be detailed below

described.

At the at least one clamping element, a holding frame or a contact insert can be fixed. The support frame can be known to be modularly equipped with various connector modules. About the holding frame with connector modules or the plug insert is the plug connection for the cabinet or for the device

provided.

The connector modules usually have one in each case

Essentially cuboid insulating body. This Isolierköper can serve, for example, as a contact carrier and receive and fix contacts of various kinds. The function of a thus formed

Connector or attachment housing is so very flexible. It can e.g. pneumatic modules, optical modules, modules for transmitting electrical energy and / or electrical analog and / or digital signals to be accommodated in the respective insulating body and so in

Connector modular system find use. Increasingly

connector modules also take over measurement and data-technical tasks.

Advantageously, the fastening means of the

Attachment housing around openings over which the mounting housing to the Wall opening is fixable. About the openings can

Mounting housing on the wall opening, for example, screwed or riveted. Such attachment is particularly stable and particularly advantageous in vibration-stressed environments, for example in the railway sector.

Preferably, the clamping element of the attachment housing openings on which the holding frame or the contact insert on the

Clamping element is fixable. Using these openings, the

Holding frame or the contact insert screwed to the clamping element and are connected to the mounting housing.

In a particularly preferred variant of the invention, the openings of the attachment housing and the openings of the clamping element are aligned with each other. This can be a particularly space-saving

Construction of the attachment housing can be achieved.

In a particularly preferred variant of the invention, the

Mounting housing on at least two clamping elements. The clamping elements are each arranged on the narrow sides of the frame-shaped basic shape of the attachment housing, parallel to each other. By using two clamping elements, these can be used with different sizes of the mounting housing. This allows the

Mounted housing basically cheaper to produce, because for different sizes partially the same components, here the

Clamping elements can be used.

Preferably, the clamping element consists of at least two parts, a first part and a second part. The two parts are coupled together via an articulated connection. The hinged connection is positioned between the ends of the clamping element. It is advantageous to additionally couple the two parts together via a spring element. The spring element can be arranged, for example, at one end of the clamping element. The two hingedly interconnected parts of the clamping element form at one end, the gelenkfernen end, clothespin-like jaws. The other end forms Flebelarme through which the jaws can be brought into an open position against the force of the spring element. Without force the spring element presses the jaws in a closed position.

Preferably, the spring element is a coil spring or a leaf spring. Such components are available at low cost in the market.

Preferably, the attachment housing has at least one web within the frame-shaped basic shape. The clamping element has a corresponding, on the web positively engaging gripping hook. The gripping hook is formed on a part of the clamping element and positioned at the gelenkfernen end of the clamping element. The gripping hook supports the above-described jaw function. The gripping hook is pressed by the jaws to the web. As a result, the clamping element can be fastened to the mounting housing without tools. If two clamping elements are used, they are identical in construction. In this case, a web is integrally formed on both narrow sides inside, to each of which a clamping element can attack.

Preferably, at least one fastening means for a sleeve housing is integrally formed on the outside of the frame-shaped basic shape. By externally mounted fasteners, the interior of the connector relevant components can be used. It has been shown that at least two diagonally to each other

arranged fastening means represent a sufficient fixation possibility for a Tüllengehäuse.

FIG. 1 shows a perspective view of a

The attachment housing 1 has a frame-shaped basic shape 2. Within the frame-shaped

Basic form 2 is a Flalterahmen 3 for connector modules (not shown for promotional reasons) attached via a screw 4. The Flalterahmen 3 and its operation is

For example, from EP 0 860 906 B1 known. On the outside, diagonally arranged on the frame-shaped basic shape 2

Fastening elements 5 formed for a spout housing. The

Fasteners 5 include keyhole-shaped openings 6, in the grommet can engage. Since the grommet is not the subject of the present invention, this is neither shown nor described in detail. In Figure 2, two clamping elements 7 are shown in perspective opposite. The clamping element 7 consists of a first part 8, which has a joint receptacle and a second part 9, which has a mating condyle, which engages in the joint receptacle of the first part 8 to form an articulated connection 1 1. The two parts 8, 9 are coupled to each other via a spring element 10. The spring element 10 is designed here as a spiral spring.

The two hingedly interconnected parts 8, 9 of the

Clamping elements 7 form at one end, the gelenkfernen end, clothespin-like jaws 12. The other end forms Flebelarme 13 through which the jaws 12 can be brought into an open position against the force of the spring element 10. Without force the spring element 10 presses the jaws 12 in a closed position, as shown in Figure 2.

In Figure 3 it can be seen that the spring element 10 'can also be designed as a leaf spring.

It can be seen from FIGS. 4 and 5 that the attachment housing 1 has at least one web 14 within the frame-shaped basic shape 2. The clamping element 7 has a corresponding thereto, on the web 14 positively engaging gripping hooks 15. The

Gripping hook 15 is integrally formed on the first part 8 of the clamping element 7 and positioned at the gelenkfernen end of the clamping element 7. The
