Description

Integrated main divider for telecommunications technology

The invention relates to an integrated main divisor for telecommunications technology and is based on the problem of how to achieve a significant reduction in the spatial size of the divisor and thus the switchboard or how to reduce the number of shunting and separation strips and the number of components on the side of the control panel with a reduced number of connections.

The main coupler is known from DE 3728368, so-called. rod divider. For such dividers, mounting troughs as known from EP 0 743 700 are used. DE 39 17270 also includes connecting slats, which are equipped with contacts in both directions, as well as an upgraded movable or detachable storage tank. Similar to e.g. SI 8811480 provides the so-called solution for the above solutions. cutting contacts with a spacer for contactless contact for cable leads without the use of a soldering iron EP 0 296 095 shows the use of double-sided double contact, but only for cable heads for telecommunication connection units. Based on the aforementioned solutions, the technology of production of main dividers and assembly units for mounting telecommunication laths and overvoltage protection, which are very large in space, is available today, which results in high investment costs, frequency problems, a high degree of so-called. overhearing, high material consumption, problems with poor transparency or even the lack of transparency and, last but not least, the problematic approach to the use of protection and measuring methods. Thus, for example, Known older digital telephone exchanges requiring twenty-two 240 x 600 x 400 mm cabinets to install the required technical facilities for 2200 subscriber telephone connections. The most recent digital telephone exchanges known so far still required six cabinets of the dimensions specified.

According to the invention, the integrated telecommunication main divider comprises at least one shunt strip equipped with knife contacts, each of which is provided with two slots for receiving conductors and / or at least one separator strip with two types of contacts and two gas arrester tanks. In that case, said shunt strip in each of the two regions, preferably in its upper region and lower region, comprises two types of knife contacts, each of which is open and on each side, preferably above and below, comprises one gap. The contacts mentioned above are preferably spaced apart with respect to each other. In addition, a shunt panel for routing the conductors is installed in the shunt. For mounting the shunt lath, an assembly tool is designed that is designed to allow the coupling to be mounted by the switchboard. Furthermore, there is provided a housing that is adaptable to the shunt bar and serves as a cable carrier, and is preferably provided for receiving at least sixteen pairs of conductors. Further, a measuring assembly is provided comprising a dual measuring plug for simultaneous hugging of two contacts of the same pair and is connected via an intermediate cable to a contact module intended for connection to the separation strip. In addition, the shunt strip can also be mounted on a double C-. An H-profile mounted vertically or horizontally in the divider.

The divider strip according to the invention further comprises centrally arranged rows of chambers for laughing conductors, except that it is rotatable around the hinge of the carrier so that the grounding contact is interrupted during rotation. Furthermore, the integrated gas storage tanks are covered by a removable tank in the separation strip

cover. Furthermore, the separation strip comprises contact pens, which are interconnected with the solder, which in the case of overcurrent will melt, causing a break between the control panel side and the line side. In this case, the rough protection is performed by a separating strip and the fine protection by a protective plug. In the separation strip, the gas arresters are so selected that, in addition to the response voltage above the upper voltage value, the closing pressure of the gas arrester is below the value of the more permanent voltage peaks of the power supply.

The integrated telecommunications engineering main divider 1 of the invention on page 2 of the switchboard (Fig. 1) comprises shunt contact strips 7. Each of the latter is provided with blade contacts 10 (Fig. 5) arranged in two rows in the upper region 8 and lower area 9 of lath 7 (Fig. 4).

As can be seen in FIG. 5, each of said contacts 10 is provided with a spacer 11 so that incoming conductors al are possible and the same pairs (Fig. 5) from the input side 2 of the control panel can be connected by means of contacts 10 with conductors al ', bi' on the output side, which it also represents the shunting side. The lath 7 can e.g. it includes connectors for 4 x 8 pairs, which corresponds to 4 x 32 pin contacts 10, such that the end contacts are labeled a32, b32 or. a32 ', b32' (Fig. 10). Further, the shunt strip 7 of the divider 1 is provided with an intermediate partition plate 40 (Fig. 6) with ribs 21 for routing the conductors.

In FIG. 7 shows an embodiment of a divider shunt strip 7 whose contact box 23 enables shunt pairs to be shunted. In this case, the shunt strip 7 is provided for the attachment of the housing 27 (Fig. 8), which serves as the cable carrier. This enables the mounting of the shunt lath 7 to the shunting side as soon as the telephone exchange is constructed. The clamp 29 is adapted to different cable thicknesses (Figs. 8 and 9).

The shunt strip 7 is mounted in the divider 1 by means of a support 30, which is made as a U or double L profile. This ensures that the cabling is turned by the switchboard and that the corresponding clamp 29 of the fitted housing 27 or. lath cable carrier 7.

In FIG. 10 shows a lath 7 having two types of knife contacts 10 in the upper region 8 and the lower zone 9, each of which is provided with a spacer on its upper and lower sides. detail according to Fig. 10 (bottom right) to ensure safety break-through distances. In case of failure of mounting contacts 10, by mounting the nameplate 31, it is possible to realize the so-called nameplate.

In FIG. Fig. 11 shows the assembly and / or assembly progress. installation of shunt lath 7 in the divider. In doing so, the lath 7 is temporarily fixed to the mounting tool 34, which is meanwhile temporarily attached to the trough 27 on the profiles 35. From this temporary position (Fig. 11 above), the lath 7 is then rotated to the working position (Fig. 11 below).

Unlike the prior art shunt strips consisting of eight plastic parts and 168 to 172 technologically demanding metal contacts, the splitter strip 7 according to the invention consists of only two plastic parts and 42 to 44 metal contacts.

In the further implementation of the shunting strip 7 of the divider 1 (Figs. 27 to 29), it is possible to use a double C or essentially an H-profile 149. For the installation of the lath 7, it is essentially an H-profile 149. This is used as a honeycomb-designed router 152 conductors arranged in the central part of the lath 7 and equipped with a foot 155 with snap pins 154 for attachment to said profile 149. In this way, the installation of the wiring harness 147 is even simpler, and the clamping earth connection 148 via the shielded jacket 157 and the corresponding contact 151 are made possible.

Further, a divider 1 according to the invention provides a measuring assembly 43 (FIG. 12) comprising a dual measuring plug 39 for simultaneous hugging of two contacts of the same pair and is connected via contact cables 135 to a contact module 44 intended to be connected to the separation strip 45.

The divider strip 45 of the dispenser 1 according to the invention is designed with two integrated tanks 46 gas arresters 48, 79 for rough protection (Fig. 15). In FIG. 16 shows the prior art separation strips consisting of a variety of complex components that can be replaced by a single divider strip 45 of the distributor 1 according to the invention. In addition, at junction 45, it is possible to retrofit the complex 54 for complex protection (Fig. 18), the fine protection assembly 55 (also Fig. 18) and the thermal protection assembly 56 (again Fig. 18), in different plugs 94 (FIG. 15) of the respective structure, examples of which are illustrated in FIG. 19.

The detachable lath 45 is rotatable about one of the longitudinal sides (Fig. 14), allowing measurements to be made, e.g. ground resistance measurements of lines and others. During the rotation in the direction of arrow 125 according to FIG. 25 around the circumference or. of hinge 60 of carrier 61 according to FIG. 14, the grounding contact is interrupted on one side of the carrier 61 of the lath 45 first on one side and then on the other. This makes it possible to perform line measurements without the influence of the gas arresters 48 installed in said tanks 46.

Also, for mounting the separation strip 45, a mounting tool 65 is provided on the longitudinal profiles or. brackets 61 attached to the respective double C-, respectively. H-profile 118 (Fig. 1) mounted vertically or horizontally in the splitter 1. On one side of the lath 45 there is a snap tooth 66 (eg Fig. 14).

The detachable lath 45 comprises two types of blade contacts 72, 73 (Fig. 20) in the central region of the lath 45, two interconnected arrays of sections 70, 71 are available to guide the conductors. Each of the halves of the separation strip 45 comprises two sets of storage tanks 77, 78 of gas arresters 79 to provide rough protection for telephone lines and switchboard.

The coarse protection assembly is integrated in lath 45. It is possible to perform measurements of gas arresters using external measuring plugs 44 (Fig. 12) without having to remove the reservoir 77, 78 as e.g. with prior art solutions.

Thermal current protection on the gas arresters themselves 79 (Fig. 15) is possible eg. s tkzv. thermoclip 81, whereby excessive heat causes overcurrent to short circuit and drain excess current into the ground.

In the version of the separation strip 45 according to FIG. 24 it is possible to open the circuit to the hot gas arrester in the case of so called. contact contact 230 V at 50 Hz. These are contact pens 84 connected to the solder, which in the case of overcurrent will melt, causing a disconnect between the control panel side and the line side.

One of the further advantages of the present invention may be that the coarse protection is performed by a separating strip (45) and the fine protection by a protective plug (94) according to FIG. 20.

With the separation strip 45, the contacts in the vertical direction are made without delay. Between the two parallel types of gas arresters 48 of each half of lath 45 (Fig. 15), a grounding strip 90 is installed in the middle. Because the gas arresters 48 are mounted on plastic supports, they can be removed and replaced in the event of damage based on measurements made after rotation of the lath 45 around its axis and the removal of the cover 92.

In addition, at the divider strip 45 of the divider 1 according to the invention, each gas arrester 48 can be so selected that, in addition to the response voltage above the upper voltage value, the closing pressure of the gas arrester 48 is below the value of the more permanent voltage spikes of the power supply.
