The invention relates to a contact device for detachable connection of the instrument block with a fixed conductive tyres with at least one contact element, as well as off of it unbent containing mounting shelf contact point of the flat material; a connecting part for connecting the contact point with the wire; with the body of insulating material with a compartment for receiving the contact block formed from the contact part and the connecting part; and a mounting shelf for connection with the connecting part has a through hole for a fastening means.

A significant area of application of the contact devices of this type are electrical switchgear, in particular, for low voltage, in which dash units contain a combination of switching devices, as required for the operation of the motor drives. The value of the instrument blocks depends among other things on providing power and is selected from a raster of a standard size, so it is good to use all available space.

The contact device with the aforementioned features is known from the patent for utility model DE 29505257 U1. The contact block when it is placed in the housing, which for this purpose comprises two connection is controlled locking elements halves. Building on its part is held by preferowanych locking elements in the holder, which is equipped with similar Windows holes in accordance with the number required in General contact blocks.

Other similar contact device with these characteristics has become known from DE 3729454 NW. Contact blocks here are made of flat material and have forked end to education facing each other of the contact elements. The case with multiple compartments receives a corresponding number of contact blocks.

In General for supply and drainage of the instrument unit, respectively, required three or four contact blocks, which interact with correspondingly spaced stationary conductive tires. It is essential that the contact pressure in each of the contact blocks has set a sufficient value, which is given only by the corresponding contact block. Due to the deviations in the location of the conductive tyres and contact blocks may, however, be the relative offset of functional groups and thus, due to the mechanical pre-stress, harmful reduction of the contact pressure.

The basis of the invention in this regard is the task of providing a simple means of compensation of deviations from specified the dimensions (tolerances) to ensure the necessary contact pressure.

This problem is solved according to the invention by the following features:

- connecting part is bent and held almost at right angles to the direction of movement and parallel to the mounting shelf mounting shelf,

- in compartment is located transversely to the direction of displacement of the partition as controvery mounting shelves and mounting shelves,

- partition contains the window to the rolling direction is located between the mounting shelf mounting shelf and connected with them the guide details

- guide component made so much thicker than the partition that the contact block in the compartment is partially movable transversely to the direction of the offset.

Unexpected despite a new principle of operation the simplicity of the contact device according to the invention is based on the fact that the interacting parts can have flat surfaces, and the possibility of displacement of the contact block inside the body contact device is achieved without any special configuration or alignment, exclusively by the Assembly of individual parts.

Rational manufacture of the contact device according to the shape of the further development of the invention can be facilitated due to the fact that the guide component with a rectangular core in the complete S-shaped and contains employee for directions in the box, a partition in the middle, and two end shelves, and end shelves take between a mounting shelf mounting details and coordinated with the width of the mounting shelf. It is the fulfillment of parts allows you to put a contact link, the guide part and the connecting part into the body contact device so that the parts find their correct position and without the aid of any device by simple connecting means (screws and nuts) can be connected in a contact block that is partially movable in the housing.

As already mentioned, for operation of various consumers are required, as appropriate, agreed dash units, contact devices which must therefore be calculated for different high load currents. Due to the form of execution of the invention is achieved in that the contact device with the same outer dimensions is applicable to a larger range of load currents. This is due to the fact that the through hole in the mounting shelf of the contact element is in the form of elongated holes, which runs in the longitudinal direction of the fixing shelves and is made of such size that the same is sent nested into each other connecting the same two contact parts is an aperture with at least a circular poperen the m section, passing through both the mounting shelves. Due to this, the load capacity current contact device can be raised from a single to a double value.

Due to the attachment of the contact over there is mutual offset interacting with conductive tire contact elements. Due to this effort, which should make the user remains unchanged, as in engagement with the respective conductive tyres come, first contact elements of one link and then contact elements of the second contact element.

Also when using the same contact links load capacity current contact device may be again raised if the compartments housing designed to receive three contact units, and two contact element nested within each other in the same direction, and the third contact element is rotated 180° and further, the elongated holes in the three mounting shelves are combined with the formation of holes, at least a circular form.

The switchgear explained above dash units can be sent and mechanically protected in different ways. In particular, for relatively large and heavy instrument block when this proved the execution of the instrument block is found in the form of retractable elements and the separation chambers of the switchgear by means of the bottoms of the sections on the pull-out section. This has the consequence that the contact elements up to their entry into the stationary contact of a body moving along a grounded bottom section. If according to the form of execution of the invention on the body contact device under the contact elements of the contact block is protruding forward protective sponge, it is possible to prevent the occurrence of emergency electric arc accidentally left in drawers extraneous conductive body.

The invention is applicable for both single-pole and multi-pole contact devices. As distribution devices are frequently used system conductive tire with three or four parallel spaced conductive tires have been preferable if the contact device adapted for this purpose and contains in this case with lots of compartments for contact blocks corresponding to the number of parallel stationary conductive tires, and that further between connecting parts of the contact blocks and the adjacent walls of the instrument block is a common insulating jacket.

As an example for the application of a contact device according to the invention above has been called the supply of tyres cameras or other systems of conductive busbars in switchgear. The mandate to engage the bearing with the contact device of the contact body is formed of such a conductive tires. The same contact device, however, are also suitable for instrument output units, in particular if they are made in the form of retractable elements. In this case, the contact body are fixed to mounting devices for leading on the cables or wires.

The invention is explained in more detail below with the aid of the figures of the exemplary embodiment. When this show:

Figure 1 - in perspective disassembled image four-body contact device and component contact block, 2 and 3 the arrangement according to Figure 1 in assembled condition, the contact block in longitudinal section and in cross section. Figure 4 - dash unit with mounted on it contact device in the future. 5 and 6 in the view in Figure 3, but in somewhat reduced in comparison to the scale, the examples run with two or three contact parts of the contact block.

Shown in figure 1 the contact device 1 includes a housing 2 of insulating material with four compartments 3 for receiving a corresponding number of contact blocks 4. This contact block is represented in figure 1 in a disassembled state, in order to clearly show the various components.

Landing is shown in Figure 3, the conductive bus 14 each and the contact block 4 contains the contact link 5 from a flat material with two spring-loaded contact elements 6. Flexural spring 7, adjacent to the contact elements 6, for example, according to DE 3731625 A1, provides proportionate contact pressure. The contact elements 6 become bent at a right angle mounting shelf 8 which is provided with two parallel elongated holes 10.

Two screws 11 with sealing washers 12 provided as the fastening means, as will be explained, serve to secure the contact element 5.

As controvery and guide surface for each contact point 5, each of the compartments 3 contains the partition wall 13, the location of which can be best seen in Figure 3. As you can see, the contact element 5 adjacent its mounting shelf 8 to the partition wall 13 so that it now rests on the housing 2 relative to the effort that appears when inserting shown on the conductive bus 14. On the opposite mounting shelf 8 of the contact element 5 side of the partition 13 of the contact block 4 contains the guide part 15 and the connecting part 16. Guide component 15 is in accordance with C-shaped basic form of the middle portion 17, and spaced at a right angle end of the shelf 18. The length of the middle part 17 or, respectively, the distance between the leaf shelves 18 are designed so that the mounting shelf 20 p is soedinenii parts 16 can come to the imposition of the Central part 17. For the passage of fastening screws 11 middle portion 17 of the guide part 15 and the mounting shelf 20 of the connecting parts 16 like mounting shelf 8 of the contact element 5 provided with aligned elongated holes 9 or, respectively, 21.

As best seen from a consideration of Figure 2 and 3, the partition 13 in the compartments 3 of the housing 2 is equipped with the Windows 22, which are aligned with the guide part 15. Box 22 covers the middle portion 17 of the guide part 15, respectively, of Figure 3, while the side pockets 23 (Figure 2) take the end of the shelf 18. Through a suitable choice of the dimensions of the interacting parts is ensured that the guide component 15 is sent without distortion of box 22 and is known as shifting, respectively, are shown in Figure 2 double arrow 24 relative to the housing 2. Thereby the contact blocks 4 can be guided independently from each other and from the position of the body 2 is scheduled for 2 conductive bus 14 so that the contact pressing depend only on the properties of the contact parts 5.

Contact parts 5, the guide part 15 and the connecting parts 16 parts are manufactured using a simple workflow as cutting, piercing, flexible, or, respectively, flared, flat work surfaces. When mon is even and the introduction of the compartments 3 of mutually oriented and receive their mutual connection and simultaneously connected with the housing 2 by screws 11. Significant here is the calculation of the partition 13 and the guide part 15 so that the guide component 15 extends past the partition wall 13 and thus also after tightening the screws 11 and nuts 19 remains a gap, which provides mentioned the possibility of displacement of the contact block 4 relative to the housing 2.

Below the contact parts 5 passes respectively extending from the housing 2 protective sponge 27, which improves in switchgear with the bottoms of the compartments reliable protection from accidental electric arcs.

From figures 1 and 4 it is seen that the housing 2 of the contact device 1 around the perimeter of the holding protrusions 25. They are located in parallel rows to the one shown in Figure 3 by a distance 26. Due to this, there is formed a groove, whereby the contact device 1 may be injected into the cutout of the wall 28, as shown in the Figure 4. The wall 28 refers to the box-shaped body 29 of the instrument unit 30, which is on the front side of the switching, control and protective equipment 31. The contact device 1 in the example according to Figure 4 is equipped with four contact blocks 4, while the rest of the compartment 3 of the housing 2 is empty. It can optionally be supplied with an additional contact block, if, for example, the system tokoprovodyaschym corresponding switchgear contains three phase wires and one neutral wire.

In the beginning it was mentioned that the contact device according to the invention can be equipped with the same dimensions of the contact blocks, which contain, respectively, two or three contact point. In this regard, figure 5 illustrates an example implementation that uses the contact units 32 respectively with the two contact parts 5. Both link are nested into each other in one direction, and due to the oblong holes 10 in the mounting shelves 8 have holes for the passage of fastening screws 11 is sufficient, that is, at least corresponding to the diameter of the screws 11. Due to the attachment of the contact elements 6 both contact parts 5 are mutually shifted. Therefore, when nadhani contact blocks 32 on the conductive bus 14 can't doubling of demand in the power, as it would have occurred, if the contact elements would be aligned on the same line with each other.

In another example, run on 6 provides contact blocks 33, respectively, with three contact units 5. In this case the position of the two contact parts 5 corresponds to the arrangement according to Figure 5, while the third contact element 5 is in a position rotated 180°.

In order to align the contact block 33 in accordance 6 with high load with what osobnosti current, next there is a second connection piece 16, which is similar to the contact parts 5 is nested in one direction with one another with the contact element 5, are available in standard execution of the contact device (Figure 3). Also here, the elongated holes 9 (Fig 1) allow the passage of fastening screws 11. Thereby the contact blocks can be manufactured using standard parts from single to triple load current. Accordingly dash units according to Figure 4 can be provided with contact devices in standard sizes and with standard box enclosure, but with a variety of switching, control and protective equipment for building switchgear.

Electrical connection apparatus 31 with the contact device 1 can occur in a known manner by means (not shown) of the cables, which are secured on the mounting parts 16. For this purpose, the elongated holes 34 (Figure 1). They allow in the case of the contact block 33 in the sense, as already described, by means of a single clamping screw to connect the cable with the two connecting parts 16. Cables can be laid in the box-shaped body 29 of the instrument block and withdrawn forward in the right place through the CTE is rste receiving apparatus 31 of the base plate. It is expedient in the box-shaped body 29 to position the insulating casing 35, which is shown in Figure 3 as a separate part. The casing 35 also improves the reliability of protection against leakage currents and emergency electric arcs.

The contact device 1 according to the invention was described above in connection with plug-in control unit 30, which it solves the problem of connection with the feeding conductive tires. It may be provided that lead to consumers cables connect directly to the switching apparatus 31. If, in contrast, should be made possible rapid replacement of the instrument unit, it is advantageous form of execution of instruments section in the form of a sliding element, which has split contacts for power supply and outputs. These plug contacts can be formed of the same contact device 1.
