The invention relates to a splitter having raster-matched connections of incoming and outgoing conductor conductors which are part of connecting springs in an insulating carrier and arranged in rows on at least one side of the carrier according to similar conductors for communications, in particular telephone facilities.

In the case of splitters of this type, which are mostly built on their own room-height racks, the aim is to keep the connection density as high as possible, ie to fit as many subscriptions as possible per unit volume. In this case, the distance between the connecting springs is often only 5 mm. Such splitters are required that the wire connections for e.g. the a and b conductors of the outgoing lines (grouping lines) are arranged according to very similar conductors, i.e. that the a-conductors of the subscriber group of the telephone exchange are, for example, the b-conductors of this subscriber group. the wires are initialized, so that their use (grouping, modification, new joining) is greatly facilitated always on the basis of the same permanent order. Due to the very dense arrangement of the connecting springs of similar conductors of different wires and the use of 2 & 6600 higher frequencies and higher bandwidths, the coupling capacitances between adjacent connecting springs become very large, so disturbances between separate wires, e.g. crosstalk is inevitable.

In order to avoid such disturbances, it is known in electrical equipment to twist the movable connecting wires or cables necessary for connecting different plant parts. The electrical ends of these connecting wires or cables, whose separate conductors of different colors must then be twisted open and carefully handcrafted, corresponding to separate codes, must be connected to the interface element of the plant in question.

The object of the invention is now to provide such a divider as described above, so that even the narrowest fitting and the arbitrary design of the connecting springs can in particular avoid capacitive coupling between adjacent lines.

According to the invention, this object is achieved in that the connecting springs belonging to separate lines running in even or odd-numbered rows are crossed and that the even and odd-numbered connecting springs are provided with metal surfaces such that the partial capacitances of the connecting springs of adjacent conductors before and after crossing are at least equal. It is thus ensured that at least the connections of the outgoing lines (group lines) remain in a clear and regular order and that the harmful sub-capacitances thus generated before or after the cruising point are effectively compensated or even overcompensated on metal surfaces, depending on the size of these sub-capacities.

According to another embodiment of the invention, the connecting springs together with the metal surfaces form a stamping piece. In this case, the parts of the connecting springs already form part of these disconnecting capacitances after the cruising points, which may be brought to the required size by additional metal surfaces.

Other preferred aspects of the invention will become apparent from the exemplary embodiments shown in the drawings and described below.

In Fig. 1, reference numerals 1 denote an insulating material base provided with lateral, hook-shaped wire guide elements 2. On the front side of the insulating support 1, pin-shaped electrical connectors protrude, which, corresponding to the example of a splitter in telephone exchanges, include separate subscribers. johti-mi.in. Correspondingly, the subscriptions a1 and b1 of the subscriber 1 and the subscriptions a2 and b2 of the subscriber 2 are marked in the drawing, etc. For the sake of clarity, only the subscriptions of three subscribers are shown in the drawing, to which only the wires of the subscriber 1 are connected. It is noted that from the incoming line belonging to the subscriber 1, only the conductors 3 and 4 are connected to the busy ends of the terminals ai and bl by winding, while instead the leads 5 and 6 of the subscriber 1's output lines (grouping lines) are connected to the busy ends of the same terminals ai and bl. In the same way, the other raster-matched connectors of the other subscribers are connected, in which case the connectors of the a-conductors are in each case arranged in a vertical row and the connectors of the b-conductors in an adjacent vertical row. Connectors ai, bl; a2, b2; a3, b3, etc. are parts of the connecting springs which are molded into the er. It is clearly seen that the ai, bl, resp. a3, b7> etc. the connection springs are crossed inside the insulating support without touching each other, while instead of the even connections a2, b2, resp. a4, b4, etc. The connecting springs pass straight through. In addition, all connecting springs, i.e. both even and odd, are provided with metal surfaces Fal, Fbl; Fa2, Fb2, etc., which have a corresponding magnitude in order to compensate for harmful switching capacitances before the junctions 7, i.e. in the region of connecting springs arranged according to similar conductors, and thus always have a neighbor of a different conductor type, so before the capacitances. thereafter are at least equal, so that harmful crosstalk between adjacent subscriber lines is prevented.

The exemplary embodiments according to Figures 2-6 are part of a so-called separation and coupling rod formed by a plurality of flat, insulated supports 3 and 9 layered on top of each other.

The figure shows a divider in which the connections of the a and b conductors of separate subscribers arranged in a raster-like manner again protrude arranged according to similar conductors. In this case, ai, bl; a2, b2, etc. the connections of the wires entering the splitter, while a'l, b'l; a’2, bf2; a'3) b’3, etc. are the connections of the outgoing wires (grouping wires) with openings between them for 10 separator and connection plugs. Incoming wires can be fitted in the openings 11. Fig. 3 shows a first spring point, corresponding to the section line A-A according to Fig. 2, in which the connections arranged on each side of the line A-A are shown. According to the proposed arrangement, there are interfaces, e.g. ai, bl; a'1, b'l; a2, b2; a'2, b'2, etc. parts of bent and angled connecting springs which are arranged inside the support 8, 9 so that their associated contact points of the separators overlap and support each other. Thus, in Fig. 3, the contact points of the separators of the connecting springs a1-a'1 are at 12, while the contact points of the separators of the connecting springs b1-b'1 are at 13.

Accordingly, the separator contacts of the connecting springs a2-a * 2 are located at 14 and of the connecting springs b2-b'2 at 15 · As the figure shows, in these spring positions the connecting springs ai and bl, resp. a2 and b2, resp., their spring branches leading to the terminals 16 of the surge protectors, resp. 17, at point 7 without contacting each other, wherein according to the embodiment according to Fig. 1, the connecting springs are provided after this cruising point 7 with metal surfaces Pal, resp. FBL.

As can be seen from Fig. 4, which shows a view of the section B-B in Fig. 2, the connecting springs do not intersect at this spring point, so that their metallic surfaces Fa3 and Fb3 are adjacent so that the partial capacitances of adjacent pairs of connecting springs before and after the cruising point 7 are at least equal. The described arrangement and design of the connecting springs is kept the same in all dividers, in which case it does not matter whether the even or odd connecting springs intersect. The connecting springs can then form an embossing part which can be economically manufactured with the metal surfaces. Likewise, the metal surfaces Fal, Fbl, etc. can be evenly distributed over the entire spring cross-section after the cruising point 7.

Figure 5 shows a section of a divider such as that described above. Here, the contact points of the isolator, e.g. 13, and the connections of the surge protectors, e.g. 16, are observed. In addition, in a schematic representation, the position of the metal surfaces in the distributor is observed, which, depending on the conductor
