The invention relates to a connector block for cable terminations of communication cables and control cables used for connecting, disconnecting and measuring NIN cable cores, as well as for connecting electrical structural elements, mainly for overvoltage shields. Distribution plates and connecting plates for cable terminations are known in which solder joints or screw joints on the side of the electrical installation of the cable end couplings are reduced in height from the edges of the plate inward. In one type of construction, tubular pins are provided with clamps, with groups of voltages in the corresponding grooves of the insulating base. These distribution and connecting plates are provided with holes transverse to the longitudinal axis of the connecting pins. Since the transverse holes in the outer row of plates lie at the height of the bridge, the inner row of plates and the inner row of plates are located displaced in the vertical direction relative to the outer row of plates, the installation wires can slip through the outer row of plates and connect to screw clamps of the inner row of plates (German Patent No. 1058120, Cl. 21 s 27/02 and German Patent No. 1415201, Cl. H 01 R 9 / However, in these cases, the wiring guide is interrupted. As a result, when skewed wires last Others touch the outer wall of the inner row of plates and the screw clamp, which makes installation difficult. The known distribution block (German Patent No. 2714448 for telephone sets with pre-formed wire guide channels connects the incoming and outgoing lines to the connecting elements Between two adjacent double rows of connecting elements, there are two guide shells for the incoming and at least one wire for the wires of the outgoing lines. With this device, incoming lines are connected to the connecting elements on one side, and outgoing lines leave a distribution block on the opposite side. The disadvantage is that for each row of connecting elements a double thickness of plates is required, as a result of which unfavorable use is obtained, the volume of the plates and the excessive height of the distribution block are obtained, which largely determines the construction height of the cable end device. The known connecting block of telephone installations with pre-molded wire-guide channels, (German patent No. 2558306), in which a simpler supply of the installation wires to the connecting elements is achieved, however, incoming and outgoing installation wires to the connecting elements are possible only on one side. In addition, with this arrangement of plates for one connecting

pads required double plate width. Moreover, the connecting elements and plates of insulating material are inseparably interconnected. Defective connecting elements cannot therefore be replaced.

On the basis of their structural design, such distribution and connecting blocks cannot be used for cable terminations with a cable compartment to be poured.

A cable end coupling is known, in which electrical components of the structure can be inserted in prefabricated frames in the cable compartment. The electrical components of the structure are located in box-shaped depressions and, through sliding contacts, are electrically connected to the connecting elements. In order to connect these connecting elements, which are located in the cable closure room, with other connecting elements entering the electrical installation room, additional contact elements are needed. The connection of connecting elements in two or several planes, which are mostly straight along each other, is produced with the help of parts or single piece joints (German Patent No. 1690784 and GDR Patent No. 74874).

This cable end coupling makes better use of the construction depth of the enclosure, however, it is difficult to access individual electrical components of the structure, in particular, if it is necessary to replace defective capacitors or fuses.

For this reason, with other known cable closures, the electrical components of the design are disassembled on the side of the electrical installation room of the connecting block in the chambers between the connecting elements. This is especially true for connecting blocks with overvoltage protection devices.

The interconnecting pads described above provide good accessibility to surge arresters, however, as a load of wealth, it should be noted that stores are firmly connected to connecting plates and end couplings, because this increases the need for space and tools.

JO A further disadvantage of an overvoltage protection plate of the type PLUs S 10 is that the number of connecting pins is twice as large as that of a surge protector.

The aim of the invention is to provide a connector block for the cable terminations of the communication cables and control cables, in which the load bone is increased despite multiple operation and cost-effective production is ensured. The basis of the invention is to develop a connector block for cable terminations, which, thanks to the expedient design of the insulating housings connected to each other in a series of insulating housings, allows for any expansion that has a small need for space, which can be used in clamping, separating and transitional terminations and which makes it possible, thanks to the arrangement of contacts at the connecting elements, to additionally insert measuring and disconnecting plugs, as well as cassettes with electrical elements designs. At the same time, it should be possible to supply the installation wires with a ho0; accessibility on both sides to the connecting elements and the connecting elements should be made of simple stamped parts and replaced in case of

 needs

The problem is solved due to the fact that each insulating body has a plate designed to accommodate contacts that have

The end section is a meandering section, the openings and channels of which are closed on the same plane on both sides by adjacent intermediate plates or outer plates. The protrusions located on the intermediate plates and the outer plates interact with the holes and channels of the plate in which

A swarm of placed contacts and fix the contact elements in their position. Bushing holes are made on the outer sides to the clamping part of the contact elements in the plate intended for their placement. The adjacent contact elements rotated respectively 180 relative to the plug contact and the sliding contacts entering the chamber are arranged in rows with each other in the plate, Izol The housings are detachably interconnected.

The holes and channels in the carrier plate of the contacts, as well as the elevations and protrusions of the intermediate ppastin, are rotated 180 ° relative to the vertical baseline of the left half opposite the right half.

Sliding contacts entering the chamber are fixed in the plate - carrier of contacts one above the other in rows.

From the outer sides to the clamping part of the contact element, there is a passage through the hole dp of guiding the wires in the carrier plate.

On both sides of the carrier plate of the contacts, a wedge-shaped expansion with grating-like partition walls is made in the limit of the holes.

To the carrier plate of the contacts in the chamber, geometrically closed fastened one another against the other, the protrusions and at the head end are parallel opposing fixing elements.

The projections are suitably made in the form of a dovetail. In the contact carrier plate, there is an opening in the bottom of the chamber in which a grounding contact is connected, connected to the grounding bar.

This opening is made in the form of a round hole or in the form of a slot. To both outer sides of the carrier plate of the contacts on top of the wedge-shaped extension, locking cams for a fitted cap are protected against dust In another embodiment, without sliding contacts, insulating plates with geometric clamping are laid between the carrier plate of the contacts and contact elements within the wire guide 6

channel in the grooves of the plate - carrier contacts diametrically opposite.

The diametrically opposed grooves in the contact carrier plate and the insulation plates are designed to be the same.

Conductive channels, molded on both sides of the plate - carrier of contacts, are made on the outer sides with sector-like, and at the opening holes they are conically widened upwards.

In the sectorial back of the conductor channels of the carrier plate of the contacts, directional stop spikes are molded down on both sides.

The sectoral expansions of the conductive channels, molded to the plate-carrier of contacts, are made at the intermediate plates and at the outer plates so that they overlap the mounted bundles of wiring wires. The sector angle is about 30,

Intermediate plates and outer plates close the chamber in the contact carrier plate in the vertical direction.

Cover plates on the side facing the plate - the contact carrier correspond to the outer contour of the intermediate plate, in

While the outer side of the cover plate is made flat.

The connecting element consists of a single conductive contact strip, provided with a bend at the bottom edge of the carrier plate of the contact and a loose part that is inseparably connected at the head end.

At the contact strip of the connecting elements there are cutouts, which are split together with cams, which are molded against the plate - carrier of contacts. In one embodiment, a curved sliding contact is formed to the side contact strip. In another type of embodiment, the sliding contact is made as a separate high-stamped part and is permanently connected with the contact strip.

In addition, the sliding contact, made in the form of a stamped part, is connected to a contact part 7, 1

Soi thanks to the appropriate contact pressure.

The connecting block consists of several insulating housings connected to each other in a row, into which the contact elements for four or five twin cores, respectively, are inserted. Typically, cable terminations for communication cables and control cables use connecting pads within eight to one hundred paired wires. According to the invention, it is possible to manufacture connecting pads for any other number of napHbtx wires.

The insulating body consists of a plate designed to accommodate the contacts Id and 1b, bounded on the side by two identical intermediate plates 2a and 26. At the same time, the intermediate plates 2a and 2b simultaneously serve to limit adjacent contact plates 1a and 1v in the case of addition in a row At the head end, the corresponding connecting block is closed with the outer plate Za and Sv and at the main end with the outer plate 4oi and 4b. and 8b

24488

The outer plates 3a, 4b, 4a and 4y on the side facing the Koiftact plate 1a and 1c are designed as an intermediate plate 2 a and 5 2c.

The difference between the intermediate plate 2a and 2b consists only in the fact that the outer side of the outer plates Za, Zv, 4a and 4c is made 10 flat. As a consequence, it is also possible to manufacture connecting blocks for four or five paired cores as the smallest structural unit.

(Fig.13

On the contact plate cx, 1 in on both sides, in the direction of the middle, there are four or five holes 5 on each side in vertical directions and, to them at an angle of 90 20, channels 6 for mounting contact elements.

The holes 5 in their contours correspond to the contact elements, which ensures a reliable and durable 25 fit.

The meandering section of the carrier plate of contacts lex and 1 in is shown in FIG. 3 and 10. The offset-inserted contact elements give 30 the opportunity to significantly reduce the construction height of the connecting block or to increase the loading capacity per unit area. Transversely with holes 5 in the carrier plate of contacts 1 & On both sides there are five conductive channels 6, which communicate with the clamping part of the contact element. Due to this, grazing and pinching of the installation wires in channels 6 are avoided.

In the contact plate 1a, the same effect is achieved for guiding the wire by means of four through-holes 8, respectively. The conductor channels 6 on both the detectable sides are sector-widened and arcuate from above. In addition, the introduction holes 9 are wire guides. channels 6 from above are extended conically.

In contrast, to lengthen the electrical leakage path within the openings 8 on both

the outer sides of the contact plate 1b are wedge-shaped extensions with lattice-shaped partitions 10. Following .9. Therefore, in both embodiments, the inlets are clearly visible from above. In addition, installation wiring is foreseeable. FIG. Figure 5 shows how the contact elements are inserted into the contact plate IQ. For fixing the contact elements, as well as for closing the holes 5 and the channels 11, intermediate plates 2cx and 2c or outer plates Z., 3 V, 4 cc and 4 are used. on the head and main ends of the connecting block. Intermediate plate 2cx. and 2i and outer plates ZS (, Sv, 4 (X and 4 also perform the function of electrically separating the drainage paths and air gaps. On both sides of the intermediate plate 2a and 2b there are extension lugs 12 and 13 and under in the second corner, protrusions 14-16 are attached to them with the help of which the grooves 5, the wire guide channels 6 and the channels 11 are closed, in the embodiment with wire guide channels 6 at the points of intersection of the wire guide channels 6 and connecting elements for potential separation Capacity 17a and 170 plas The contact carrier carriers 1c are clamped by insulating plates 18a and 186 (indicated by dashed lines in Fig. 9). The left insulating plate 18 oi is / -shaped, and the right insulating plate 18 V is right-angled. On the reverse side of the plate is a contact carrier 1b, the insulation plates 12c (and 12e are fixed in the recesses 17q and 17 diametrically opposite the front side. The insulation plates 18 and 18 amps are additionally fixed by the protrusions 16 of the intermediate plate 2 or y. Zb and 4c plates. The connecting block is provided with a conductive contact strip 19, which is made at the point of exit from the la and 16 contact plate with bend 20 and at the main end with an ear for soldering 21. At the head end, the contact strip 19 is bent and cut out so that the bracket part 22 could be stuck and soldered, welded or attached. In the assembled clamping part 7 there is a clamping screw 23. To the side of the right 810, a plug contact 24 is made for disconnection and measurement. The connecting element is designed so that it is possible to reliably connect, respectively, two conductors more than conductors with diameters of 0.4 - 1.7 mm. The cutouts 25 located in the contact strip 19 serve to secure the connecting elements in the insulating body. Cutouts 25 on the contact plate 1a and Ic install preformed cams 26. With the contact plate 1a, at the contact strip 19, the sliding contacts 27 are located at a 90 ° angle, which are located with their ends in the horizontal direction in the groove 28. placing the sliding contacts 27 in the middle of the plate - carrier contacts 1a. In the groove 28 of each lex contact plate in rows one above the other on each side are four sliding contacts 27, the ends of which are opposite each other and create electrical contact with the surge arrester or other structural elements in the plug 29 or in the cassette . Since overvoltage arresters must lie near ground potential, a ground bus 30 is mounted below the junction block. The ground bus 30 has earthed contacts 31, respectively, fixed in the opening 32 on the bottom of the groove 28 and providing ground wires for protection against overvoltages, i To reduce electrical transient resistances, the galvanized sliding contact 27 forms with the contact strip 19 one structural unit, i.e. performed in one piece. It is also possible to make the sliding contact 27 as a separate part, and then either connect it non-detachably with contact strip 19, or connect them with appropriate contact pressure, such as spring pressure. The decisive condition for this is that the necessary contact resistance is observed in the conditions of long-term operation, taking into account the various applications of cable ends. out couplings.

in the chamber 28 of the contact plate 1 o. opposing protrusions 23 are arranged to serve for lateral direction of the cassettes (not shown Hbii; .equipped with electrical structural elements. Instead of the cassettes, plugs 29 with dischargers for voltage distribution or other electrical structural elements are placed in separate chambers 28 (Fig. ). At the top of the chamber 28 are locking elements 34, covering respectively formed molded parts, a plug 29 or cassettes. Due to this, the female parts simultaneously prevent the arms from extending oh plate 1a if the plug 29 or the cassettes are pressed into the mechanical load chambers 28.

Contact plate lot and 1c, intermediate plate 2 and outer plates Za, Zb, 4ci and A & They are made of high-quality thermoplastic material using injection molding technology. Considering the appropriate fixtures, the installation of building parts can be significantly mechanized. In this case, the structural parts are stacked on top of each other in the following sequence: outer plate 3 and 3, provided with contact nonocoil 19, contact plate lo, and 1c and intermediate plate 2a and 2B, the sequence between the contact plate and intermediate plate 2a and 2 b depending on from the desired number of connecting elements can continue. The assembly is completed with other outer plates 4a and 4e.

If there is a sliding contact 27, it is possible to place an external plate Sv with the profile of the intermediate plate 2 according to FIG. P. The connecting elements are then superimposed so that the cams 26 enter, or engage the notches 25, and the connecting elements are fixed.

812

Now the contact plate i B with clamped insulating plates 18a and 18 v is fitted onto the outer plate 3 equipped with connecting elements so that the connecting elements fit into the holes 5. The plug contact 24 is then inserted into the groove 35. The free holes 5 the contact plate 1, directed upward, are inserted the connecting elements rotated 180. The intermediate plate 2 is again put in place, the holes 5 and the conductive channels 6 are closed.

The assembled parts of the connecting block are fixed on the holding plate with the corresponding recesses. For this serve fixing

cams 36, formed on the lower end of the carrier plate of contacts lex and b. In the same way, it is possible to screw together or pull together separate insulating shells. In spite of

reliable performance of the contact elements, with the installation or with the necessary switching work, the clamping screw 23 is twisted. In this case, it is possible to replace

defective contact elements and re-use the rebuilt connecting pads.

In the embodiment with a wire; by the guide channels 6, the withdrawn connecting wires are bent around the fastening cam 37 and are carried out as a bundle of connecting wires under a sector-like extension. In this way and in the assembled state, the connecting block will receive the required appearance and the necessary wiring of the wires.

In order to protect the contact elements from piercing, as well as the electrical components of the structure, which are located in the plug 29 or in the cassette, the mounted connecting block is protected (not shown) with a transparent sheet. At the end section of the contact plate Iq and 1c, locking cams 38 are formed on both sides, providing the installation of a protective cover.
