Federal Republic of Germany-Förbundsrepubliken Tyskland (DE) (7I +) Berggren Oy Ab (5I +) Distribution equipment for electrical equipment, in particular for telephone installations -Fördelningsanordning för elektriska anläggningar, speciellt för telefoncentraler (6l)

The invention relates to a dispensing device according to the main patent No. 55280 for electrical appliances, in particular telephone installations, having conductor control channels for receiving electrical wires running in an insulating body, the inputs of which are divided in groups on the front sides of the device and arcuately extending to the front side of the device. in the region are located close to the connecting members arranged therein, whereby the outlets of the channels for the circuit-connected incoming and outgoing lines running in several parallel planes and intersecting are located immediately next to each other and to the connecting and connecting elements separated and then built into the device.

Such known dispensers have subscriber and connection elements stored in a separate piece, i.e. in several superimposed flat pieces of insulating material, which form integrated parts of the dispenser. These subscriber and connector elements may, for example, be formed of single or double clamp connectors, for the direct electrical connection of incoming lines to the lines leaving the device, or as isolating contact elements in pairs of detachable, respectively, disconnected contact connectors. These subscriber-resp. the wires are usually brought to the junctions of the connecting elements in a more or less bundled form, and several are counted together in the wiring ducts, from which they are divided and connected to their respective subscriber points by time-consuming work.

Due to the described construction method, difficulties arise both in the design and installation of the distribution device, especially in the distribution devices of the telephone exchange. As in telephone technology, as in all fields of messaging technology, the number of subscribers, i.e. the number of connection points, is constantly increasing, it must be taken into account when designing a distribution device that the supply of connection points is sufficient for several years. Thus, for example, when designing a telephone exchange, it must be taken into account that sufficient distribution points are reserved for a longer period of time, for example for 30 years, in order to be able to connect new subscribers during such a period.

The purpose of the main patent No. 55280 is to eliminate the remaining difficulties in the known devices by providing a dispensing device which is capable of reducing the financial costs when setting up the device and of ensuring that the device is easily adapted to the prevailing requirements.

The object of the present invention is to further improve the suitability of the dispensing device for the prevailing connection requirements, as well as to increase the operational reliability of the device and to facilitate maintenance.

According to the invention, this is achieved in this way and is characterized by the invention that in the distribution device the components are arranged in the spaces reserved for them to be inserted and pulled out separately, each of which forms a single connection point for incoming and outgoing connection elements. In connection with the advantages of individual arrangement of cables and installation in cable ducts, it is now possible to provide a distribution device which does not require any prior measures to install incoming cables or the necessary components, thus having only as many cables and components as are currently needed. Restricting the components to only one connection point in each case, i.e. to a single subscriber, results in the failure of only this single component in the event of a fault, without disturbing the nearby subscriber connections.

A further development of the invention is possible in that the component consists of an insulating material support with connecting springs and connecting elements for projecting and outgoing lines freely projecting on one of its support sides, from which the connecting springs of the incoming lines can be connected to the ground

3,57510

The connecting elements can be formed as solder pins or a crimp connection lug in a known manner. Such an overvoltage fuse may be provided for the incoming lines for each separate connection spring, so that each private subscriber line is protected against excessive voltages. The connection springs for incoming lines passing through the entire component may be provided with notches or recesses so that individually tuned capacitance smoothing surfaces can be provided between immediately adjacent components, through which a reduction in crosstalk can be achieved.

According to another embodiment of the invention, the connection springs of both the incoming lines and also of the ground connection elements protrude freely from the support side sides opposite the connection elements, between which overvoltage fuses are arranged. These overvoltage fuses are most preferably fixed, i.e. soldered or welded in place. The fixed arrangement of the overvoltage fuses increases the load capacity of the device and sets the destruction time of the component and the overvoltage fuses so high that the break in the event of a load is limited to a few special cases.

According to another embodiment of the invention, the connecting springs of the incoming lines are separable. In another embodiment of this feature, a test plug is inserted into the second support side of the insulating material carrier containing the connecting elements, an accessible opening for separating the connection springs and connecting the part of the connection spring connected to the overvoltage fuse to the test voltage source. This test plug is most preferably coated on one side with an insulating layer, so that when the test plug is inserted into the opening, the part of the connection plug without electrical contact without the contact plug is pushed away from the other part of the connection spring. At the same time the overvoltage fuses are connected. Overvoltage fuses can thus be tested in a very simple way for their reliability.

Other advantageous details of the invention will be apparent from the working examples shown in the drawing and described below.

Fig. 10 is a substitute diagram for the components of the embodiments of Figs. 5, 6 and 9.

Fig. 11 is a substitute diagram for the component according to Fig. 7.

In the exemplary embodiments according to Figures 1 and 2, 1 denotes a U-shaped, metal, grounded support frame, which in both free arms is provided with open guide slots on one side, with retaining openings 3 provided in the open side area. These layer slots are further inserted into these guide slots. are provided with a number of conductor ducts arranged in parallel planes. The layer components 4, which may be one-piece pieces or consist of several interconnected parts, are provided in the device end side area with two retaining elements in the form of a flexible retaining hook 6, which engage the retaining openings 3 when the layer members 4 are pushed into the guide slots.

The support ring 1 together with the layer components 4, as well as the connection components described below, forms a distribution device, i.e. a part of the distribution plant. The dispensing device can be connected to a vertical or horizontal rail (not shown) on the back side of the device, in the embodiment example on the back side of the support ring 1, also in a stand not shown.

In the exemplary embodiment, the 4 marked layer components are formed in each case from a flat insulating body, which is provided on both sides with layers 5, which layers 3 in turn have rib-shaped guide elements 7 for the components described below. The insulating material body has two ducts 8 and 9 in parallel planes, which are in each case divided into separate ducts by intermediate steps. Figure 2 clearly shows that the ducts 8 and 9 in successive planes run from opposite sides of the dispenser in an arc to the front side 2 of the device, so that the inlets of these ducts 8 and 9, which are staggered, will be on the side surfaces and the outlets of these ducts on the end side 2.

In the exemplary embodiment, conductor channels 8 are used for matching incoming lines and conductor channels 9 for matching outgoing or arranging lines. The conductor ducts are arranged in such a way that the outlets of the wires belonging to the connections 5 57510 are the end side of the device!] A 2 immediately next to each other. The layer components 4 are arranged at a distance from each other in the support ring 1 so that spaces are formed between the adjacent layer components 4 for the components described below.

In Figures 1 and 2, two components 12 are arranged in these spaces marked 10. These components are controlled by guide bars 7.

As shown in Fig. 4, the structural member 12 has a flexible retaining element 13 which engages the retaining opening 14 in the region of the conductor channel of the layer structural member 4. Most preferably, a pliers-type pull hook 15 is used to pull the component 12 out of the insulating body formed by the layer components 4, the Haa shoulders Ib of which can be inserted into the recesses of the retaining elements 13 on either side of the component 12. By compressing can be pulled out to the gripping position.

Fig. 4, as well as Figs. These connection springs are provided with recesses with which they can be inserted into the retaining bladder 22, and its thermoforming joints are connected to the insulating material carrier 23 of the structural part 12. Fig. 4 shows an unshaped and a right-shaped retaining bladder 22 on the left.

There are separate openings 24 in the insulating material carrier 23 of the embodiment between the connection springs 17 and 1. In the area of these openings 24, the incoming and outgoing connecting springs of the two-wire subscriber line make contact (see also Fig. 1). For example, inserting a test plug into this opening 24

As will be seen in more detail in the following figures, the connecting springs of the incoming lines pass through the component 12 along their entire length to the rear support side, where they are connected to the rear support side in the presence of an overvoltage fuse 23, a bifurcated spreading spring 2b as a grounding element. The spreading springs 2b can be inserted into the gap 27 in the support ring 1 and engage it at its edges 2ö.

As shown in Fig. 2, the connecting springs are provided with alternating intersecting capacitance smoothing surfaces 29 to reduce the crosstalk attenuation of the subscriber components below each other.

Fig. 3 shows a second design of the earth conductor element formed by a U-shaped spring 30 which resiliently supports the support ring 31.

Figure 5 shows a separate structural part 32, the shape of the insulating material carrier being shown by a dotted line. The connection springs are provided with connection elements shaped as compression connection lugs 33.

The connection springs 34 of the incoming line a and b conductors as well as the grounding element 35, which is connected to the protective plate 3b partially surrounding the component 32, protrude freely from the rear support side. A surge fuse 25 is soldered or welded in between. The figure also clearly shows that the connection springs of the incoming and outgoing lines are electrically connected at the disconnection points 37.

A similar embodiment of the structural part 3ö is shown in Fig. B, in which the connecting elements are formed by winding pins.

In the component 39 according to Fig. 7, the connection springs 40 are bent several times and in each case consist of parts 41 connected to the connection elements and parts 42 directly connected to the overvoltage fuses 25. The overlapping ends of these parts are bent and form disconnections 43. From the end of the device 2 the test plug 44 shown in Fig. 6 is inserted and inserted between the ends of the parts 41 and 42. The test plug 44, which is connected to the test voltage source, is provided with two separate tongues 45, which are partly completely surrounded by the insulating layer 46. The upper sides 47 of the protruding tongues 45 are also coated with an insulating layer, whereas instead the lower sides of these tongues 45 form contact surfaces and can make electrical contact with the parts 42 of the connecting springs 40. For the function test of the overvoltage fuses, the connection system is thus separated so that only the earthing circuit remains connected.

In the component 4b according to Fig. 9, an overvoltage fuse 49 is soldered or welded between the connection springs 50 of the incoming line and the grounding element 51. Parts 50 and 51 are tensioned relative to each other. The connecting springs 50 have a bend 52 with a small distance 53 from the ground element 51. The overvoltage fuse heats up strongly when the AC load is pulled, the solder of the overvoltage fuse evaporates and the contact point closes so that the overvoltage is applied to ground. The earth fault element 51 and the connecting spring 50 form a holding contact.

Fig. 10 shows a substitution diagram of the embodiment according to Figs. 5, 6 and 9 with a separator point 37 and an earth fault, while Fig. 11 shows the coupling structure of the component 39 according to Fig. 7. In this case, 54 denotes the point of separation of the connecting springs of the incoming and outgoing lines and 43 the point of separation of the connecting spring 40 of the incoming line according to Fig. 7, already described.
