c) An adapter, which can be attached to the base body mentioned, and

d) a clamping element.

The attachment plug element is characterized in that the clamping element can be attached to the adapter such that the mounting wall is clamped between the outer section of the plug element and the clamping element.

An add-on plug device element with the features mentioned can be very easy to mount in a wall opening by placing the mounting wall between the outer portion and the clamping element is clamped. Except for the wall opening, which is often already prefabricated, does not have to be on the assembly wall further arrangements are made. All for attaching the connector element rather, necessary components and facilities are integrally formed on the connector element itself. The assembly will this not only simpler, but also better quality, since it is less of depends on the care and skill of the respective fitter.

According to a preferred embodiment of the adapter, this is by means of a Thread can be attached to the base body of the plug element, wherein the adapter has an internal thread and the base body a corresponding one Has external thread. Alternatively, the adapter can also be connected via a bayonet or a locking mechanism connected to the base body become. It is also possible to screw the adapter to the base body connect to. The above options for attaching the adapter to Basic bodies have the advantage that many are known from the prior art Plug device elements are already set up for such connections, so that (with a use other than the cultivation) with a Cover housing can be connected. This existing training of In the present case, plug device elements are used to attach the adapter exploited. Furthermore, it is due to the interposition of the adapter between the clamping ring and the base body of the plug device element possible, always the same clamping element together with different designs (Thread, bayonet, etc.) of the base body, since only the one for Basic adapter (always the same design for the clamping ring) must be used. In this way, the manufacturing technology can be cheaper Way a program of adapters and clamping rings are provided, which the assembly of conventional connector elements different Types allowed.

The adapter is preferably designed such that it is secured against rotation Installation in the wall opening allowed. An anti-rotation device is in principle by any shape of the adapter deviating from the circular shape, provided that Wall opening has a corresponding shape. In particular, the Adapter on its outer circumference circular with a radially protruding nose be formed, the nose in a corresponding recess of a circular wall opening can intervene. The twist-proof installation of the Adapters prevent the entire attachment plug element from rotating relative to the mounting wall.

According to a preferred embodiment of the clamping element, this is as one Cap nut is formed, which has an internal thread with which it is attached to a corresponding external thread of the adapter can be screwed on. Such a screw connection is easy to produce and can be done on the other hand infinitely adjustable, so that a fastening in assembly walls different Thickness with the desired clamping force is possible.

The threads on the union nut on the one hand and the adapter on the other are preferably designed self-locking in the latter embodiment, thus an undesirable independent loosening once screwed on union nut difficult for later use respectively is excluded.

Furthermore, the clamping element is advantageously on the with the mounting wall Contacting contact surfaces designed to prevent sliding, so that a Displacement relative to the mounting wall complicates respectively is prevented. This contributes to a clamping element designed as a union nut in addition to loosening protection. The escapement can Example can be achieved by using the contact surfaces on the clamping element teeth or projections directed towards the mounting wall are formed.

The attachment plug element preferably includes a seal, which between the outer section on the one hand and the mounting wall on the other hand, can be arranged around the inside of the mounting wall to seal against the outside. Such a seal is used Pinching the mounting wall between the outer section and the clamping element pressed with the required force.

Furthermore, the adapter is preferably designed such that it is connected by means of a Internal thread on an external thread of the base body of the plug device element can be screwed on and in the fully screwed on Condition engages on the base body. This snapping can, for example, via a happen on the adapter trained nose, the fully screwed State to lie in a corresponding recess of the base body comes, the nose is preferably beveled such that it relieves enters the recess and exits it only with difficulty. The attachment of the adapter on the base body is thus primarily done on that on both parts trained thread, the locking for securing the screwed together Condition and an undesirable automatic release of the Prevents adapters.

a) ein Adapter wird am Grundkörper des Steckvorrichtungselementes befestigt;

b) der Grundkörper wird mit dem daran befestigten Adapter durch die Wandöffnung gesteckt;

c) am Adapter wird ein Klemmelement derart befestigt, dass die Montagewand zwischen dem Außenabschnitt des Grundkörpers und dem genannten Klemmelement eingeklemmt wird.

The invention further relates to a method for mounting an add-on plug device element in the wall opening of a mounting wall, wherein the add-on plug device element can in particular be one of the type explained above. The process includes the following steps:

a) an adapter is attached to the base body of the plug element;

Figures 1 to 3 show the same extension plug element designed according to the invention 1, which is e.g. to a device socket of a power connector can act according to DIN VDE 0623, EN 60309-2. in this regard However, details are not relevant in the context of the present invention and therefore not shown in detail.

The device box is to be fastened in a wall opening of an assembly wall 5. It has a base body 2 consisting of an outer section 2a and an inner section 2b, by definition the outer section 2a the outside and the inner section 2b on the inside of the mounting wall 5 comes to rest. The matching plug can then be in the outer section 2a be plugged in, and on the inner section 2b the connection is made on the 5 installations located inside the mounting wall.

The base body 2 of the attachment device box is essentially in one of the State of the art trained manner. In particular, he points an external thread 10 (Figure 3), which when using the can as Coupling socket serves a rear socket housing (not shown) tightening. Others known from the prior art Connection options for a socket housing exist in one Bayonet lock, a snap connection or a screw connection by means of Screws.

The existing external thread 10 on the device box 2 is according to the invention exploited to screw an adapter ring 4, which for this purpose has a corresponding internal thread 9 (FIG. 3) on its inside.

If a different precaution, such as a bayonet lock, on the base body 2 would be provided, the adapter ring 4 would have to correspond with the corresponding one Connection technology.

The adapter ring 4 also has a radial and axial direction towards the outer section 2a protruding projection 12, the axial projection of this Projection 12 in the fully screwed-on state of the adapter ring 4 in a recess 13 snaps into the base body 2 and thus the adapter ring 4 secures against unwanted automatic loosening.

The device box with the screwed adapter ring 4 can then by a circular wall opening can be inserted in the mounting wall 5, the Outer section 2a of the base body 2 on the outside (left in the figures) and the inner section 2b on the inside (on the right in the figures) of the mounting wall 5 comes to rest. Because the outer portion 2a has a larger diameter than the wall opening in the mounting wall 5, it does not fit through the wall opening through, but lies circumferentially on the edge of the wall opening on the Outside of the mounting wall 5. As can be seen in particular from FIG. 3, can be a between the outer portion 2a and the mounting wall 5 (Three-dimensionally shaped) seal 3 made of rubber or a comparable Material can be inserted to prevent the entry of gases or moisture To prevent the inside of the mounting wall 5.

As can be seen from Figure 1, the circular wall opening has a radial Recess 11 in which the aforementioned radial projection 12 of the Adapter ring comes to rest, so that the adapter ring 4 and thus the entire Attachment socket 1 is inserted in the wall opening so that it cannot rotate.

After inserting the device box with the adapter ring 4 into the wall opening can from the inside of the mounting wall 5 ago as a union nut 6 trained clamping ring on the external thread 7 formed on the adapter 4 (Figure 3) are screwed. The threads 7 and 8 on the adapter ring respectively the union nut 6 are, as can be seen from Figure 3, self-locking trained to complicate an independent loosening of the screw connection.

Furthermore, the union nut 6 has on the mounting wall 5 facing Side on a toothing, which in the tightened state, a rotation of the Union nut 6 prevented relative to the mounting wall 5.

The add-on device box 1 according to the invention can thus be proportionate easy to install, with only a circular wall opening of the appropriate size is to be provided with a recess 11 in the mounting wall 5. Subsequently can be attached by simply screwing on the device box Union nut 6 on the adapter ring 4, the connection with the desired clamping force can be tightened.
