Description

762 35 Mounting base for electronic adapters or switching units. - Monteringsunderlag för elektriska anpassings- eller kcpplingsenheter.

The electronic control of various equipment and processes requires a number of different signal adapters, controllable switches, auxiliary relays or the like on the input and output side of the central unit, which are collectively referred to herein as matching! switching units.

The mounting bases of such matching or coupling units are now manufactured separately for each purpose as a single unit comprising a certain number of matching or coupling units. Such fabrication results in certain standard configurations, making it cumbersome to modify, expand, or shrink the fabricated assembly to accommodate changes in operating conditions. Expansion requires a completely new device, either to replace or replace your old one. Shrinkage is possible by disabling some of the device's matching or coupling units, but the chassis structure cannot be shrunk.

The object of the invention is to provide a mounting base for electrical fitting or connection units which can be assembled into desired units from as many prefabricated parts as possible, which can be easily changed afterwards by changing, adding or reducing the manufactured unit.

To achieve this object, the invention is based on a vessel frame self-adjusting from other connections (e.g. U.S. Pat. No. 4,171,862), which consists of, for each mating unit, a separate plastic molding made of chassis units, the sides of which are gripping members for connecting the base-frame units. In this case, different and easily modifiable assemblies can be assembled from the same prefabricated parts.

In order for this vessel frame known per se to be suitable for use in the mounting base object of the invention, the mounting base according to the invention is characterized in that a circuit board extends for a certain distance between the base frame units connected to each other to form an electrical connection between each adapter or connection. The length of the circuit board can be cut in each application to correspond to the length of the substrate body, which in turn depends on the the number of electronic fitting or connection units required for the application.

In a preferred embodiment of the invention, the gripping members consist of dovetail joints, the height of which determines the free air gap between the base frame units, and each end of the base frame units has a dovetail notch into which a dovetail rail fitted prevents dovetailing between the base frame units. The free air gap between the chassis units acts as an insulating gap and allows air circulation for cooling if necessary.

In the following, some embodiments of the invention will be described in more detail with reference to the accompanying drawings, in which Fig. 1 shows a perspective view of the connection of a fitting or switching unit to a circuit board part.

Fig. 2 shows a top view of the base frame unit belonging to the part of the mounting base according to Fig. 1, and Fig. 3 shows the unit according to Fig. 2 in a perspective view.

Fig. 4 shows a side view of a matching or switching device assembled from the parts according to Figs. 1-3, to which a circuit board connecting the units has been added.

Figure 5 shows the fitting of Figure 4 or the end of the switching device seen from the arrow V direction.

Figure 6 shows the fitting of Figures 4 and 5 of the coupling device or a single module, that is the assembled components of Figure 1-3 under the module, seen from the end, that is, the direction of the arrow VI of Figure 5.

Figure 7 shows the module of Figure 6 from the bottom side.

Fig. 8 shows a fitting or coupling unit which differs from the embodiment of Fig. 1 in that the connector pins of the fitting or coupling unit are intended to be mounted on the sockets of a circuit board part 3 76235 si, whereby a detachable connection is formed.

Fig. 9 shows a mounting base according to a second embodiment of the invention, on which the fitting or switching units according to Fig. 8 can be mounted.

In the case of Fig. 1, the circuit board part 2 is permanently fixed by soldering to the connection terminals 15 of the matching or coupling unit 1. In addition, both ends of the circuit board part 2 have screw terminals 4, the connection terminals of which are also soldered to the circuit board part 2. As can be seen. and between the screw terminals 4.

The unit according to Fig. 1 can be attached to the substrate frame unit according to Figs. 2 and 3, which is made as a plastic mold so that the circuit board part 2 fits inside the edges of the unit 3. The end edges of the circuit board part 2 engage behind the cams 7 while the circuit board part 2 rests on the support surfaces 10. When the unit according to Fig. 1 is mounted on the chassis frame unit according to Figs. 2 and 3, a fitting or coupling module is formed, by connecting which fitting or coupling devices of the desired size can be built. This interconnection of the modules takes place by means of dovetail joints 5 and 6 on the side surfaces of the base frame units 3. The other side has dovetail-shaped protrusions 6 which fit into the dovetail notches 5a in the protrusions 5 on the other side. At the same time, the height of the protrusions 5 determines the distances between the modules and the free air gap, which forms the electrical insulation gap between the modules and allows the circulation of cooling air. In order to prevent the dovetail connections 5, 6 between the modules from opening during transport, handling, installation and use of the devices, the modules are still locked together by means of dovetail notches 8 made at the ends of the base frame units 3 and a dovetail rail 9 fitted thereto. There are V-shaped grooves on both narrow sides of the dovetail rail 9.

When the required number of modules, e.g. 10 to 20 pieces, have been assembled into a single unit, an electrical connection is formed between the matching or coupling units 1 and the wiring connector 11 on a circuit board 2a extending the entire length of the mounting base and having contact pins 2b attached to the other ends of the circuit board parts. 4.

In the embodiment of Figures 8 and 9, the interconnected base frame units 3 have one integral circuit board 2 ', into the terminal holes 14 of which the terminal pins 15 of the unit 1 can be inserted to form an electrical connection between the units 1 and the wiring connector 11'. Also in this case the edges of the circuit board 2 'stick below the cams 7. The screw terminals 4 are only on the other side of the circuit board 2 '.

The circuit board 2 'is provided with transverse notches extending over most of its width at the free air gaps 21 between the base body pieces 3.
