Description

1 84678

The present invention relates to an installation part with devices for placing and fixing it in duct ducts, in particular in handrail ducts, comprising an almost square housing with a bottom opening , and contact rails 10 provided on the end sides with devices for connecting electrical conductors.

Device mounting boxes for mounting standardized devices, e.g. switches, sockets, etc., in 15 conductor ducts are widely traded and are well known, for example from DE-U-7047743 or DE-U-7728102. On the bottom side, they are equipped with a device that allows attachment inside the conductor ducts. In order to insert the conductors passing through the conductor channels into the device mounting box 20 and to connect them to the mounting part, openings, for example, are formed in the walls of the box.

DE-B-2838371 discloses a multi-pin socket whose plugs are permanently wired by means of contact strips. These contact rails are equipped with plugs at their ends. When it is desired to install this multi-pin socket in the cable duct, a trough-like lower part is attached from behind and a flat front panel with sockets is fastened from the front by means of screws to the cover which closes the cable-30 channel.

The disadvantage of all known and commercially available mounting parts for ducts is the relatively large space requirement. This is because the mounting parts used are standardized parts, the standard being adapted to the size of the known and also standardized sockets under the plaster. Although the 2 84678 ka ducts are the subject of continuous further development, which has led to a reduction in size while maintaining the same efficiency, these commercially available mounting parts themselves set limits to this technical development.

5

Another limiting factor of the known solutions is the fact that the connection between the conductors and the installation parts can in practice only be realized on the construction site. Pre-installation in a workshop is only possible on a limited basis. Connecting the cable ends to the connections of commercial mounting parts is often time consuming, as is the subsequent installation of the parts in the device mounting box and the installation of the device mounting boxes in the cable duct. In addition to this, the part still has to be routed in the 15 ducts themselves, for which new installation measures are required.

This state-of-the-art protective contact rail is not upgradable for a number of reasons. First, it is disadvantageous to position the terminal contacts so that in each case the geometric groove of the terminal contacts connected in parallel is located on a different connecting line. Especially when connecting so-called corner plugs, this causes space problems because the angle-25 plugs are in the way of each other. In addition, minimizing the width requirement of the housing cannot be achieved due to the selected pole contact arrangement. Thirdly, it is disadvantageous that the housing parts have to be brought into contact with and connected to the duct cover one by one. Pressing the cover 30 into the housing seam may adversely affect the operation of the sockets. Fifth, fitting the individual parts of the sockets to the duct cover is very complicated. When the cover is normally only placed in place on the bottom of the channel 35, the cover can also be removed when the plug is pulled out. It is disadvantageous for six rails that have contact rails with plugs at their ends that can only be connected using 3,84678 fixed cable plugs. Seventh, it is disadvantageous that the end walls of the housing can be removed and that they are asymmetrical. The loss of these parts during installation is as far as possible.

The object of the present invention is therefore to provide an installation part of the type described above, which can also be installed simply, quickly and securely on site and can be connected without special structural elements and whose external dimensions can be reduced without compromising electrical safety.

This task is solved by extending the lower part over the upper part in one end surface in one piece so as to form a conductor connection space located asymmetrically with respect to the median side wall of the same housing, closed by a cover and provided with a conductor insertion opening. on the underside of the housing and can be operated from above the housing.

Thanks to the connection spaces arranged asymmetrically with respect to the central plane of the conductor duct, it is simply possible to insert the conductors from either the upper or lower duct into the mounting part by turning 25 mounting parts without having to pass through the dividing plane in the duct. The cover-closing connection compartments and the top of the housing make it easier to connect the wires, especially when quick-connect connectors or similar are used as wiring harnesses, and it allows a radical reduction of the external dimensions without compromising electrical safety. The access of the fastening devices from the top of the housing enables a particularly simple and quick fastening of the fastening point in the cable duct.

The asymmetrical conductor connection spaces formed on each end wall of the housing, in particular together with the permanently connected conductor connection devices in each connection space, make it possible to install the parts in a particularly simple manner, for example , is known for. According to a preferred further developed embodiment of the invention, the cover of the cable connection space is articulated to its lower part by means of a skull hinge and can be closed by means of a latch device. The upper part of the strain relief device is also preferably articulated to the lower part by means of a membrane hinge. In this way, the entire lower part of the mounting part, including both the connection space and the strain relief device, can be produced by a mold injection method in a single operation.

Since it is possible to use identical components, the manufacture can be further simplified when two of the kaa-20 game connection devices and possibly the through wiring are arranged symmetrically on both sides of the longitudinal center plane of the housing. In this case, identically shaped metal parts can be used, which are placed in a mirror-inverted position and are retained and supported by partitions formed in the lower part of the housing.

When a thermoplastic material is generally used for the lower part of the housing, a duroplastic material is preferably used for the special upper part of the housing. This is especially true when the mounting part is a socket, because in this case the heating due to the contact resistance between the contact spring and the contact pin must always be taken into account.

According to a preferred further developed embodiment of the invention, vertical latch devices 5,84678 are formed on the ends of the lower part of the housing in order to fasten the decorative front frame.

Another embodiment of the front frame can be directly locked to the conductor channel.

5

According to a preferred further developed embodiment of the invention, the front frame protrudes over the cover of the duct on both sides and thus covers any ugly cut marks.

10

In order to cover the devices themselves or, for example, the inserted plugs and to harmonize the appearance of the pre-installed cable duct, a cover is mounted on the front frame.

15

The cover can preferably be locked to the front frame.

According to another further developed embodiment 20 of the invention, the cover is vaulted and also leaves a gap between it and the front frame in the closed state. In this way, the cover can also be closed when, for example, electrical connection cables have been pulled into it.

25

In connection with the manufacture of the contact rail, in particular the protective contact rail, special advantages are achieved because it is a stamping part in the form of a die, in which case it simultaneously forms two cross rails. In this connection, it is particularly advantageous for the cross-rails to be uniformly shaped with bushings forming hollow rivet arms and for the earthing contacts to be riveted by means of these bushings. This eliminates the need for separate hollow rivets.

35

By simply replacing the stamping tool, simple holes can also be punched into the cross rails instead of through the 6 84678 road, for example when it is desired to attach other components, such as the solid pins used in France.

The invention will be explained in more detail below with reference to the structural examples shown in the drawing, in which:

Fig. 1 is a perspective view of a mounting part shaped as a double socket, 10

Fig. 2 shows a top view of the device of Fig. 1, partially opened,

Fig. 3 shows a cross-section of the conductor duct and the mounting part 15 placed therein in an exploded view,

Fig. 4 is a front view of the cable duct and the mounting part placed therein and the attached front frame,

Fig. 5 shows a protective contact rail and cross rails and earthing brackets attached to them by riveting,

Fig. 6 shows a cross-section of the stamping part 25 of Fig. 5 along the line VI-VI,

Fig. 7 shows a modified structure of the stamping part of Fig. 5, and Fig. 8 shows a section of the stamping part of Fig. 7 along the line VIII-VIII and a ground pin placed in place.

Figure 1 shows a mounting part 1, which is a double-point-35 socket and which is intended to be used in conductor channels.

The housing consists of a lower part 2, for example of thermoplastic, and an upper part 3, which is preferably of 7 84678 duroplastic materials. Support legs 4 are formed on the lower surface of the lower part 2, by means of which the device 1 rests on the bottom of the conductor channel, and guide cams 5, which can be placed in the longitudinal grooves of the conductor channel. The upper and lower parts 5 2, 3 of the housing are fastened to each other by means of rivets.

Each end face of the housing has a conductor connection space 6, 6 'which is offset with respect to the same end surface of the housing and is integral with the lower part 2 of the housing.

10

The cable connection spaces 6, 6 'consist of a fixed lower part 7 and a fixed cover 8 articulated through a membrane hinge 11, the upper surface of which is formed by a duct partition extension 10. The opening 12 for inserting the cable 17 is located next to a central plane passing through the duct partition 10.

The cover 8 and the lower part 7 of the connection spaces 6, 6 'are locked together by means of a latch device 9, which can be opened again 20 only by means of a tool, for example a blade of a screwdriver.

The upper part 3 of the housing has two sockets 13 with protective contacts 14, which are of the German earthed plug-25 socket type. Between the sockets 13 there is access to the central fastening device 15 at the bottom of the lower part 2, by means of which the device 1 is fastened to the conductor channel.

A conductor end 17 is fixedly mounted in the rearmost conductor connection space 6 'in order to speed up the installation work to be carried out on the construction site.

Fig. 2 shows a view angle into the interior space 35 of the device of Fig. 1, in which the second connection space 6 is opened and the upper part 3 of the housing is largely cut away.

β 84678

In the open connection space 6, a strain relief device consisting of a fixed lower part 18 and a movable upper part 19, which parts are connected to each other via a membrane hinge 20, can be seen.

In addition, fixed wire connection devices 21,22 can be seen, which in this case are screw terminals. However, quick connectors, crimp connectors, solder joints or the like can also be used instead of Ruu connectors. The terminals 21 for the phase and neutral conductors are symmetrical with respect to the central plane 40, while the terminal 22 for the protective conductor 24, to which the protective contacts 14 are attached, is moved to the side.

The symmetrical arrangement of the phase and neutral conductors allows the use of identically shaped metal parts 23 mounted in a mirror-inverted manner.

All the metal parts 21, 22, 23, 24, 14 remain in place 20 and are supported by partitions 25 formed in the lower part 2, whereby a corresponding design in the upper part 3 of the housing secures the metal parts.

Figure 3 shows a cross-section of a duct 25, 25 with a mounting groove 26 formed in the bottom, a mounting part 1 and a decorative front frame 39. Due to the considerably reduced size of the mounting part 1, in particular its reduced width, there is sufficient space between the part 1 and the duct 25 fastening devices 38. -30 to suggest 17 times.

Vertical latch devices 16 are formed on the end faces of the device 1. These latch devices 16 are locked by corresponding mating pieces 16 'on the lower surface of the decorative front frame 39. In this way, an easily assembled and disassembled structure is obtained.

Figure 4 is a perspective view of a conductor duct, for example a handrail duct, seen from the outside, with a built-in double socket as an example of a mounting part. The channel 25 is covered in the conventional manner by means of an end-piece 29. In the vicinity of the mounting part, the decorative front frame 31 is locked to the channel 25, which covers the ends of the channel cover 30 on both sides. The outer frame 31 is provided with side walls 32 and a movable cover 33, which can be latched onto the side walls 32 in a closed space by means of latch projections 36. The cover 33 is vaulted and leaves a gap 34 at its lower end between it and the front frame 31 in the closed state. In this way, it is possible to close the cover 33 with the connection cables 35 already inserted in order to provide a visually pleasing device.

Fig. 5 shows a protective contact rail 24 in which two cross rails 44 are formed so as to form a shaped stamping part. A ground bracket 41 is attached to each cross rail 44 by means of a rivet-20 path.

As shown in the cross-section shown in Fig. 6, bushings 42 are initially formed in the cross rails 44, which are then inserted in the manner of hollow rivets 43, whereby they connect the cross rail 44 and the ground bracket 41 to each other.

Figure 7 shows a protective contact rail 24 'formed in accordance with a foreign standard. Simple holes 45 are formed in the cross rails 30 44. For example, a solid ground pin 46 is riveted to these holes 45, as shown in Fig. 8.
