The invention relates to electrical devices structures of communication networks and primarily can be used on the cable communication lines, sealing systems, pulse code modulation (PCM), is characterized by the presence of the linear tract of digital transmission systems (DSPS) signals of the two transmission directions and different levels of these signals regenerators linear path. On the lines sequentially, several unattended regionalnej cable with two or more cables, y coupler. Typical fan clutch imply branching of the main cable is not more than three directions. If necessary, the branching of the main cable to a larger number of areas subject to special (non-standard) coupling the cluster core cable with four or more cables are in the station branch closure. Also known y-coupler for venting a single cable ground coupling  case which has a T-shape. All known constructions of connective and y couplings do not have separation of an inner space of the housing is a flat metal screens. Use the last known only in some cable terminal devices, in particular in a shielded terminal boxes for type BM  and end sealing symmetric cable chetverochka twisting  For inclusion in a cable communication line APC you want to output in one place of the linear cable four or more stackable that can be achieved using a cascade of y-couplings in two directions  or by using the station y coupling with the appropriate number of branches (fingers). Station y coupling  his konstrukcii, because the pairs in the cable core fixed structurally twisted in polivy or beams, their position relative to each other consistently throughout the construction length of the cable and splice couplings twisting pairs in polivy or bundles impossible, as the main cable is spliced with several cables of different design, which leads to chaotic intersections of pairs in the cluster among themselves; not possible to mechanically separate the pair in the cluster into four groups and screening of the latter from each other, as in the clutch housing, there is no relevant structural elements. All this is not to put in the same cluster station y coupling a pair of one direction, but at different levels of the transmission signals, as it gives the possibility of spurious relationships of the input and output of the regenerator DSPS signals, and does not allow time to be there couple of different directions of signal transmission, as in this case there are interacting transient communication between regenerators DSPS signals in different directions, disrupting the operation of the linear tract of PCM systems. In addition, it complicates the use of station y couplings in wells phone systems, pateena external axis of the clutch cover approximately 50% of the circumference of the joint, on the inner axes 0%) complicates the connection technology cable sheath with fingers and taking into account the fact that the line can be from two to several dozen pieces y couplings, it greatly reduces the operating characteristics of the communication line, the reliability of the tightness of her sheath.The aim of the invention is a special fan clutch, allowing one to include in a cable communication line several CHP systems PCM in one place or display another purpose of the cable lines of the group of conductors and type them back in the same place, in which pairs are divided into groups corresponding to the transmission directions of signals and their levels and eliminated the electromagnetic interaction between them, provided greater access to the circumference of the junction of each of the finger sheath of cables are inserted into them, which, in addition,allows you to enable APC in the cable line without stackable, to include CHP in existing cable line in any way, without the need for cables.The goal is addressed through the following means. Branch openings through which are introduced the group of conductors from APCS, are not in the cover of the clutch, and in the middle part of the side stink he crosses all branch openings, made in the wall of the housing, one on them of the axis. Metal screen located in the casing throughout its length along its longitudinal axis, divides the inner space of the coupling into two halves, shielded from each other (hereinafter longitudinal half of coupling). Drop holes made in the body in the middle part of its side wall, divide longitudinal half of each of them into two parts, separated in space these holes. Thus, the inner space of the coupling is divided into four parts. In these four parts of the internal space of the coupling are four added pairs. Splices are protected against electromagnetic influences on each other the metal screen and the separation of parts in the space of the longitudinal halves of the coupling. Each drop hole surrounded by closed along the perimeter wall with the formation of branches of the body in the form of a sleeve, a finger to put in the clutch housing of stackable. The coupler is a compound item, the serial connection of which with the help of a pipe with a metal screen along its entire length, forming a multiple splitter clutch to enable the cable line in one place and two more the Oia pairs stackable, enter through these holes, or all pairs in the first longitudinal half of the coupling or the second, or pairs are divided between the first and second longitudinal halves of the coupling. Likewise is determined by the separation of pairs of linear cables inserted into the coupling on both its longitudinal halves. Thus, the design of the coupling determines the multiplicity of the location of the pairs of linear connections of cables between themselves and with pairs of stackable four clusters coupling. Its possible that in one longitudinal half couplings are clusters of pairs of one transmission direction, and one end of a longitudinal half of the cluster pairs of the same level, at the other end of the splice pairs of another signal DSPS, similarly positioned in the second longitudinal half coupling two cluster pairs of the second direction of transmission, i.e. the coupling design allows you to splice a pair of forward and reverse directions of transmission signals of different levels in one clutch and turn it stackable from APCS in the cable line. Its possible that in one longitudinal half of the clutch are located in opposite corners, two splice different directions, but the same level, similarly arranged in the second the other two cluster pairs different level of Signa in and to the outlet of line cables allows a pair of cable lines, which is not derived from this clutch, to splice directly in the coupling.The separation of the aggregates from the middle to the ends of the longitudinal halves allows for the selection of pairs for systems PCM from the core of the current cable cut these pairs at the midpoint of the future of the coupling, thus forming the two ends of each pair sufficient to splice them in the opposite splices of the longitudinal halves of the coupling with pairs stackable. A pair of operating links are not cut and placed in the clutch housing in its longitudinal halves from input to output line cables. For the clutch apply split along the longitudinal axis design. Therefore, the above coupler allows you to include your cabling CHP systems PCM without a break existing ties and without the use of additional cables. Location of branch holes (finger) in a number of provides free access to the fingers on both sides, which allows them to carry out the connection of the finger shell stackable entered into them, as free access to the place of connection in this case is not less than 80% of the circumference of the joint.In Fig.1 shows a special splitter clutch to activate APCS in two-cable l is zobrazen section a-a in Fig.1; in Fig.3 cross-section B-B in Fig.2; Fig.4 shows a special splitter clutch to activate one APC in single-cable line without stackable; Fig.5 section b-b of Fig.4; Fig.6 coupling to include two APCS in single-cable line without stackable; Fig.7 shows the location of the splices in the coupling; Fig.8 the location of the four clusters stackable linear cables and the latter with each other, the section G-G in Fig.7; Fig.9 section d-D in Fig.8; Fig.10 shows the arrangement of four clusters of groups of conductors from APCS with linear cables and the latter with each other; Fig.11 shows a circuit of five containers NBC-12-4 system PCM-30-4 two-cable line capacity h with one special fan clutch.Special y-shaped coupling (Fig.4 and 5) consists of a casing 1, having three parts medium 7 and the two extreme 8, drop hole 19 made in the middle part 7 of the housing of the clutch cones 17 and 18 for input and output of a linear cable, metal screen 9, crossing all three parts of the hull and branch openings 19.Coupling branches (PI.1, 2 and 3) consists of a casing 1, having three parts medium 7 and two end 8, of the branches in the form of fingers 2, cover 3 with on screen 9, crossing all three parts of the body and the fingers 2.Composite clutch in Fig. 6 consists of couplings shown in Fig.4 and 5, the elements 21, the pipe 20 with the metal screen, connecting elements 21, cones 17 and 18 for input and output of the linear cable.Special splitter coupler has four separated was added (Fig. 7-10) of the two transmission directions of signals DSPS a-B and B-a and two power levels of these signals Piand Powhere Pithe low level signal, Pohigh. In the upper longitudinal half of the clutch (Fig.8) on the left side 8 of the casing is located a cluster of 10 B-AND Pilinear cable 11 B-And B-groups of conductors 15 stackable 12, entered through the fingers 2 of the entrance APCS, at the right side 8 of the casing is located a cluster of 10 a-B Polinear cable 11 B And with groups of conductors 15 stackable 13, entered through the fingers 2 from the output of the APC.
