Abstract

In the case of a retaining device for electrical telecommunications technology apparatus units, consisting of a cable shaft which is continuous from top to bottom and is located behind apparatus units (3) which are arranged in a plug-in manner, and whose lateral boundary is provided by two opposingly constructed L-shaped angled rails (1, 2), suspension devices (22) (which are constructed one above the other like brackets and are attached to the two angled rails) are arranged at the same distance as the vertical dimension of the apparatus units. The suspension devices (22) each have a cut-out on the top rear corners of the vertical limbs and an outwardly projecting pin (peg) (57) at the lower corners, and the L-shaped angled rails each have a bolt (55) with a head and each have a hole (56) (for the pins to snap into) at a height corresponding to the cut-outs in the bracket (22). The pins (52) for the bracket (22) consist of stamped regions in the sheet metal. <IMAGE>

Description

Holding device for device units of the electrical

The invention relates to a message transmission technique Receiving device for device units of electrical communication technology, in the one from top to bottom continuous, behind pluggable arranged device units lying cable duct is arranged, its lateral boundary by two opposite formed L-shaped angle rails is given in the distance of the vertical Dimension of the devices units one above the other, console-like, on the two Angle rails attached suspension devices are arranged on their inner Upper and lower side guide rails as well as fastening devices for fastening the device units are provided and that on the top or bottom of the device unit oppositely designed guide rails are attached, and the console-like trained suspension device at the rear upper corners of the vertical legs One cutout each and one pin protruding outward at each of the lower corners has, and the L-shaped angle rails at a corresponding height to the cutouts of the console one bolt with head each and one hole each for snapping in the tenons exhibit.

Such a device is contained in German Patent 2,161,862 and will be described later with reference to FIG. Based on such an arrangement The invention is based on the object of simplifying the production of the Bring about consoles.

This task is carried out in a facility of the type mentioned at the beginning solved in that the pins for the console consist of embossings in the sheet metal.

Further improvements to the facility can be found in the subclaims.

The invention is explained in more detail below with reference to figures.

Fig. 1 shows the suspension device mentioned at the beginning.

Figures 2, 3, 4 and 5 show the console-like in different views Bracket.

Figure 1 shows the suspension device mentioned above, which is attached to the rear upper corners of their vertical legs each have a cutout 58 and at the lower corners each has an outwardly protruding pin 57.

The support rails 2 of the frame contain a corresponding amount the cutouts of the receptacle each have a bolt with head 55 and matching the pin One hole 56 each.

When hanging, the two legs of the hanging device compressed by the height of the pin 57, the suspension device between the Support profiles guided and pushed up until the cutouts 58 with the bolts 55 are in engagement and the pins 57 snap into the bore 56.

Instead of the cutouts 58 and bolts 55, resilient pins can also be used step into the receptacle, which snap into the holes in the mounting rails.

Finally, one with upper guide rails is inserted into the suspension device provided with dashed lines drawn network device 3 inserted.

Since the journals of the known designs were turned parts that were inserted into the Recording were riveted, the production is relatively cumbersome and consequently expensive. The solid pins 57 are therefore through directly into the different thicknesses Replaced hollow pegs punched from sheet steel. This is also clear from the illustration the detail a (FIG. 5), which shows a section from FIG. 4, emerges.

By pre-punching with different hole diameters, the hollow pegs with the same outside diameter with one and the same tool in different thicknesses Low target steel sheets are produced in one pulling process.

Using a die it is possible to measure the outside diameter to be adhered to very precisely, e.g.

with a fit H9. The pin can be cylindrical or to compensate the bolt hole tolerances are made conical in a defined manner.

It is therefore a significant production simplification and cheaper possible.
