ger to wire, whereby in the inserted state the connection of the components via a connector strip arranged on the frame he follows. For larger components, e.g. relays, the components are placed on a frame made of profile rails. In the case of components of a smaller size, e.g. resistors, transistors and the like, the components are on a Plate arranged and wired together.

The . the task is to create a slot which with a given installation volume the largest possible number of components in a clear and easily accessible form can accommodate. This object is achieved in that as a carrier between two superposed levels of plug-in organs three insulating plates in one for wiring purposes are firmly connected to each other at a small distance and the upper and lower plate are provided with soldered connections on one side, so that the carrier can be equipped with components from both sides. Do a further training which is the middle one The plate of the carrier is provided with soldering pins passing through the upper and lower plates, which make the electrical connection Manufacture from one support plate level to the other.

With a structure of the connector strip and the carrier plate according to the, a Clear arrangement of the components achieved. In addition, this structure is easy to replace the individual

Components possible and heat dissipation is not impaired. The middle insulating plate prevents contact between opposing soldering pins, so that the plates in can be populated more densely to save space.

The ψ & ^ η & χχφβ is explained in the following description with reference to the figures.

FIG. 2 shows such an insert in section, FIG. 3 shows a detail from the carrier plate.

In a tap 1, a carrier 2 is provided on its top are located according to Fig. 1 jumper strips 3 and protective frame 4 for magnetic ring cores. There are side recesses in the rager 5 and lugs 6 provided on the frame. The back of the slip has plug contact organs 7 in two superimposed Levels on.

The mounting plate is fastened in the slide-in frame in such a way that that when inserting the protruding from the frame rabbits 6 pass through the corresponding recesses 5 of the carrier plate. Then the plate is adjusted by one of the width of the rabbit Shifted amount and finally held with a single screw 8. This type of fastening makes the plate

temperature fluctuations expand on all sides. This type of mounting iot very advantageous, cheap to manufacture and time-saving. *) tension-free ■ ·

The formation of the deceiver can be seen from Figures 2 and 3, which is composed of the insulating plates 2a - c. The plates 2a and 2e are perforated in the same way, for example and provided with solder connections 9 fitted on one side. The plate 2b can also be perforated and equipped with continuous soldering pins, which then make the electrical connection of a Create support plate level to the other. With these solder connections Components such as rectifiers 11, transistors 12 or diodes, etc. can be connected. The carrier plate lies in each case with one hand on a square-shaped attachment 13 and 14. The slight distance between the insulating plates 2a to c creates space for connecting wires, especially for winding connections of magnetic ring cores.

In the pig. 3 shows a soldering pin 10 passing through the Dräger plates and two soldering pins 9 fastened on one side. It can be clearly seen from this figure that the middle plate 2b prevents contact between opposing soldering pins.
