Distribution strip for elektriQch.e starting, insbooondero for

The innovation relates to a distribution strip for electrical systems, especially for telephone exchanges with wire ducts used for laying incoming and outgoing electrical lines, their outputs on the strip front and in the vicinity of their individually assigned connection elements lie.

In the case of distribution strips of the Yöi-genäSntefi type, ziunshinsnds! » Msßc the Pojaerus "table srhöhtsr üisisturi— controllability and connection density on the one hand and on the other according to a clear, unambiguous order system within the connection field and wire routing space, as well as uncomplicated usability and assembly brw.

To meet the latter Requirement, the distribution strip should be designed so that, on the one hand, the number of connection points can be adapted to the existing, current need for distribution points and that on the other hand Defective connection elements installed in the distribution strip (solder connections, clamp connections, winding connections) can be exchanged in a simple way.

In the case of a known distribution strip (German Gebraxichsinuster 7132 510), in which the incoming and outgoing

The electrical lines are routed in an orderly manner in shunting eyes arranged on the edge of the strip, the electrical lines are Connection elements can be plugged into pocket-like receiving openings in the strip body in a latching manner.

The boundary walls of these take-up openings have Latching means, the counter-latching means of the dimensionally stable connecting elements cooperate. This locking means can when plugging in and pulling out the Connection elements in the area of between the receiving openings Dodge placed sxeisparungen resiliently.

The innovation is now the object of auszugeetalten a rail of the type mentioned so that, as with the latter, known distribution strip the connecting elements are individually releasably retained in the lie! Accumulating body, but the available space is not limited by the spring ausweichbaren latching means or should be impaired in its clarity.

This object is achieved according to the innovation in that the wire guide channels closely adjacent openings are provided in the strip body that between the wire guide channels and the associated openings lying, resiliently deflectable partition walls haste means have and that the Ans chin ße equipped with counter locking means lenient θ in the aforementioned openings locking are pluggable. In this case, the wire guide channels that are present in each case are advantageously in which the incoming or outgoing electrical lines are laid loosely, used as floodplains for the resiliently movable locking means or for their Carriers (partition walls) so that special loads burden the installation space Price savings for this do not have to be available. By the geometrically close assignment of the openings or the in

these fixed connection elements for functionally related electrical lines or line cores (for example for the a and b cores of the electric lines assigned to a telephone subscriber) and the one who laid these lines Wire f'IlvrnTigaicanaie will continue to opt ie before Üaiex— separability of such a wire duct and connection " unit from a neighboring unit and, last but not least, the connection density within the distribution bar improved.

According to a further embodiment of the innovation, the partition walls are provided with detent knobs which protrude into the associated openings and which have run-out inclines pointing in the insertion and pull-out directions which can be locked with locking edges of the connection elements. Here, the run-up bevels pointing in the insertion and pull-out directions can be inclined differently, for example. elements less Xraftaux «* ai_d is required than for pulling the connection elements out of the openings, so that an unintentional loosening of the connection elements from their holder can be largely excluded.

A further refinement of the furnace is thereby

given that for the support of U-shaped Döppel-

connecting elements, preferably on double clamping elements, the partition walls delimiting the elongated openings in the central area with detent knobs have, which can be locked with the unfree legs of the U-shaped double connection elements. One Particularly space-saving design and a high connection density of the distribution strip results from this, that the elongated openings on both sides,

With a vertical arrangement of the elongated Openings can in particular significantly reduce the overall width of the distribution strip.

Other advantageous details of the innovation emerge from that shown in the drawing and below described embodiment.

The manifold shown in Figure 1 consists of a plurality of stacked and in Layered building blocks 1 held in a frame (not shown), only one of which is detailed in the figure is shown. In the exemplary embodiment, the layer building block 1 is made from two identical plastic parts 2 assembled, e.g. welded together using vibrations in the ultrasonic range. All layer building blocks 1, plastic parts 2 and those between the plastic parts 2 arranged thin-walled intermediate layers 3 form the strip body 1/3 of a distribution strip for a remote

With 4 and 5 wire guide channels are designated, whose Outputs on the front 6 of the strip body 1/3 are freely accessible. As on the cut part of the Layer building block 1 clearly recognizable, run Wire guide channels 5 arcuate to a side edge 7 of the strip body 1/3, while vice versa the wire guide channels 4 arcuate to the side edge 8.

The wire guide channels 4 and 5, which run in different planes, are through the intermediate layer 3 separated from each other.

In the individual plastic parts 2 of the last body 1/3 are along the two opposite vertical boundary sides of the wire guide channels 4.5 groove-like Openings 10 incorporated which have an elongated cross section. These openings 10 are formed through the groove-like openings 10 in the two plastic parts 2 of the layer structure component 1. In this area Openings 10, the intermediate layer 3 is interrupted.

The sectional view according to FIG. 2 shows a U-shaped, flat double clamping element 11, which has two clamping slots 12 on each free leg. This double clamping element 11 can, as also shown in FIG. 1 and FIG. 3, be inserted and pulled out in an elongated opening 10 of the strip body 3 in the direction of the arrow (FIG. 3). To latch the same in the opening 10, a latching knob 12 is used, which is part of a resiliently deflectable partition wall 13 which separates the opening 10 from the adjacent wire guide channel 4 or 5. This locking knobs 12, which in the exemplary embodiment consists of two knobs belonging to the combined plastic parts 2

share (Fig. 2) is formed, is placed in the central area of the partition wall 13, so that it, like Pig. 2 shows, with a locking edge 14 of the unfree leg 15 of the double clamping element 11 forms a locking connection. In addition, the partition walls 16 opposite the aforementioned partition walls 13 also have locking knobs 17 » which resiliently in between immediately adjacent cavities 18 (arrow) can evade.

When a double clamping element 11 is inserted into an opening 10, the front edge of the free leg 15 slides on a run-up slope 19 and a relatively large inclination presses the locking knobs 12 and 17 in the direction of the arrow until these locking knobs 12, 17 lock in a form-fitting manner behind the locking edge 14. Furthermore, the locking knobs 12 and 17 have run-up bevels 20 relatively low inclination through which the double clamping element 11 can only be pulled out of its opening with a relatively large amount of force. Through dash-dotted The elastic deformation of the partition walls 13 and 16 is indicated in FIG.

Figure 1 shows that two double clamping elements 11 and wire guide channel 4 »5 form a wire guide and connection unit for a telephone subscriber. The wire guide channel 4 and the terminals al and b1 are used for laying or the electrical connection of the a and b wires of a subscriber line arriving at the distributor and the wire guide channel 5 and the terminals a'1, b'V for laying or the electrical connection of the a and b wires to a jumper line going out from the distributor. The layer module shown in Figure 1 has 4 wire guide and connection units for 4 subscriber lines.

It is seen that by the perpendicular arrangement of the openings 10 in height of the wire guide channels 4> 5 and

by utilizing the partitions 13 as resilient Latching means a very compact design of the distributor with a very high connection density is achieved. File it can in many cases be considered sufficient if renouncing the additional Latching knobs 17 and the cavities 18 for locking the double clamping elements 11 only Latching knobs 12 are used.
