Connection strip for electrical installation devices such as switches, sockets, etc.

The invention relates to a connection strip for electrical installation devices such as switches, sockets and the like, essentially consisting of a housing for housing the device inserts and a base plate, whereby the housing has at least one cutout for at least one device insert fastened to the housing in the area of the cutout by fastening elements and the devices can be connected to the mains via at least one connection terminal arranged on one end of the housing.

Such a connection strip for electrical installation devices is already known from DE-OS 36 40 207. The disadvantage of the known connection strip is that it consists of many parts and that the device inserts are difficult to assemble.

The invention is therefore based on the object of creating a connection block which is both simpler in construction and easier to install.

This problem was solved according to the characterizing part of claim 1. In the housing, a corresponding cutout is provided for each device insert, in which the device insert is secured flush with the surface of the housing and can be re-soldered using locking means.

In the connection strip according to the invention, the arrangement of the cutouts in the housing and the attachment

&ngr;&ogr;&iacgr;. locking means ensure that the device inserts can be inserted into the housing from the bottom in a particularly advantageous manner. In this way, each device insert is attached to the inside of the housing with a single movement so that the surface of the device insert(s) is flush with the surface of the housing on the outside.

Thanks to this extremely clever arrangement, it is no longer necessary, as was the case with the state of the art, to additionally attach a cover frame to conceal the fastening elements after installing the device inserts in the housing - which was more complicated in the case. The locking elements molded onto the inside also make it very simple and easy to use to connect the device inserts to the housing.

The connection of the housing to the base plate has also been simplified in a positive way, as the connecting pins molded onto the housing must be pressed into the holes in the base plate during assembly. This creates a secure and removable connection between the base plate and housing that can be made without tools.

Advantageously, this connection is designed in such a way that it cannot be opened by laymen or children using a simple tool, but only with a special tool, so that the live parts inside are safely protected.

Another positive aspect of the inventive connection strip is the simple means of fixing the connectors using fixing elements arranged on the housing or on the base plate.

Further advantages arise from the dependent claims and the following description of an embodiment shown in the drawings. The drawings show

Fig. 1 a complete connection block in diagonal >.isi <"ht,

Fig. 2 a section of a longitudinal section through the terminal block,

Fig. 3 a section through a fastening zone of the connector,

Fig. 4 a section along the section line IV-IV of Fig. 1,

Fig. 5 a section through a connection area between housing and base plate and

Fig. 6 shows a section along the section line VI-VI of Fig. 5.

In the drawings, the terminal block as a whole is designated with the reference number 10.

The connection block 10 essentially consists of a housing 11, a base plate 12 and device inserts 13 that can be locked into the housing 12, such as switches, sockets or the like.

The housing 11 consists of a housing base 14, in which cutouts 15 are arranged that are matched to the outlines of the device inserts 13, the side walls 16 and the end walls 17. The end walls 17 are each provided with one to

provided with a rectangular cutout 19 extending to the lower edge 18 of the housing 11.

As shown in Fig. 1 and 2, a latching tongue 20 is formed on the inside 21 of the housing base 14 on each side of a cutout 15 for a device insert 13.

Fig. 3 and Fig. 5 show that connecting pins 33 directed towards the base plate 12 are arranged in the corner areas of the housing 11. The connecting pins 33 are preferably molded onto the inside of the housing base 14 made of plastic. Collar-like webs 22 for receiving a plug connector 23 are molded onto the housing base 14, each assigned to the rectangular cutouts 19 in the end walls 17.

The base plate 12 fits flush into the lower, open and largely circumferential edge of the housing 11. In the area of the rectangular cutouts 19 on the end walls 17 of the housing 11, the base plate 12 has an outwardly projecting tab 26, which is penetrated by a hole 27 and serves to screw on the connection strip 10.

To fix each connector 23, two positioning pins 28 are formed on the base plate 12 approximately opposite the collar-like web 23 and a support part 29 is formed in front of the rectangular cutout 19 on the front side 17 of the housing 11.

In Fig. 3 and 4 it can be seen how the fastening pins 30 of the plug connector 23 are clamped in the internally conical cantilever-like web 22 and how the plugs 31 on the mains connection side are held by the positioning pins 28 and the support part 29.

Fig. 4 and 5 show the type of connection between the housing 11 and the base plate 12. The connecting pins 33 are provided with a longitudinal slot 34 and each consist of a shaft 35 and a locking head 36. The base plate 12 has rings 37 which are aligned with the connecting pins 33 and which are narrowed in cross-section approximately in the middle by a shoulder .!8.

When assembling the connection strip 10, first the device inserts 13 are inserted into the housing interior and firmly connected to the housing 11 using the locking tongues 20. This means that the surfaces 39, 40 of the device inserts 13 and the housing 11 lie blindly next to one another. After the device inserts 13 have been wired, the base plate 12 is inserted into the housing 11. In the process, each connector 23, which is fixed in position by the positioning pins 2b, is pressed into the conical interior of the circumferential collar web and thus held and finally securely supported by the support 29 in this intended position. At the same time, the connecting pins 33 engage with their heads 36 in the holes 37 of the base plate 12 in such a way that each locking head 36 is held by the shoulder 38. This connection can only be released by pressing the locking heads 36 together with a special tool.

To additionally secure the connection between housing 11 and base plate 12, it is possible to press a split pin 40 into the longitudinal slot 34.
