Abstract

A plurality of connecting elements (1) for plug cords (2) is housed in a common housing of a contact component (3). The connecting elements (1) extend from the front (4) to the rear of the contact component (3), where they are connected to a conductive film. The length of this film is greater than the width of the contact component and its ends are bent through 180 DEG . This section of the conductive film is connected with plug-type connectors (6) into which cable plugs (7) for the cables (8) to the transmitting devices can be inserted from the rear. This results in a compact arrangement of the contact components (3) on the frame of the distribution switchboard.

Description

Siemens Aktiengesellschaft Distributor in a telecommunication network The invention relates to a distributor in a telecommunication network, especially in a telephone exchange, the distributor being equipped with contact components which exhibit connecting elements for incoming lines at the front, the connecting elements being connected to plug-in contacts for pluggable outgoing lines at the rear.

Such a distributor has become known, for example, through German Offenlegungsschrift 26 43 167. According to this document, the internal lines leading to the exchange facility are connected at the plug-in connector. The patching lines leading to the subscribers are con15 nected to connecting elements at the front which are connected to contact springs protruding towards the rear. Due to these contact springs, the plug-in connectors for the internal lines can be plugged in at the rear of the contact components. Due to the lateral plugging-in, the plug-in connector can only contact one double row of contact springs in each case.

The invention is based on the object of being able to establish the connection to the exchange lines via conventional plug-in connectors and to adapt the number of plug-in points to the number of wires in the exchange cables.

This object is achieved by the invention according to Claim 1. The invention makes it possible to connect more than two rows of connecting elements to the plug-in contacts. By bending the ends of the conductor foil, the outgoing lines can be plugged on from the rear in a space-saving manner. As a result, the pitch width between adjacent blocks of contact components can remain smaller than in the case of plugs which are pushed in from the side. The type and number of plug-in contacts is now independent of the contact components. As a result, commercial plug-in connectors can be used which are adapted to the number of wires of the outgoing cables.

The connecting elements can be extended directly to the rear of the contact components and brought into contact with the conductor foil. However, it is also possible to provide between the incoming lines and the conductor foil two contact parts, one of which is constructed as contact spring which rests against the other one. This produces a contact which can be opened by a disconnect plug.

Advantageous further developments of the invention are characterised in Claims 2 to 5: The result of the further development according to Claim 2 is that only one contact component needs to be connected to a conductor foil. In this arrangement, it is possible to connect the contact component with the two plug-in connectors to the conductor foil in one work cycle, for example by flow soldering.

The further development according to Claim 3 makes it possible to connect the contact component and the plug-in connectors mechanically firmly to one another. In this arrangement, the conductor foil with the connected plug-in connectors is bent back on itself by 180° so that the cable plugs can be inserted in a spacesaving manner from the rear of the distributor. Due to the further development according to Claim 4, several contact components with the plug-in connectors attached thereto can be combined at a rail and, as a result, do not need to be individually screwed to the distributor rack.

Due to the further development according to Claim , the plug-in connectors and the contact component are inexpensively connected to the conductor foil in one work cycle. In this arrangement, the plug-in connectors and the contact component are held in a common receptacle.

In the text which follows, the invention will be explained in greater detail with reference to an illustrative embodiment shown in the drawing, in which: Figure 1 shows a perspective diagrammatic representation of a part of a distributor in a telephone IE 91734 exchange, and Figure 2 shows a top view of the distributor according to Figure 1.

According to Figures 1 and 2, a distributor is 5 provided at the front with connecting elements 1 for patching lines 2. These lead to a different distributor area in which the patching lines are connected to the incoming cables from the subscribers. The connecting elements 1 are inserted into contact components 3 in which eight rows of connecting elements 1 are combined.

The connecting elements 1 extend from the front 4 of the contact component 3 to its rear where they are soldered to a conductor foil 5. The conductor foil 5 is approximately as wide as the contact component 3 is high.

However, it is considerably longer than the contact component 3 is wide and is bent back on itself towards the rear by 180° with the protruding ends. At this end section of the conductor foil 5, plug-in connectors 6 are soldered on onto which a cable plug 7 for cables 8 leading to the exchange facilities are plugged on from the rear in each case. The conductor foil 5 is provided with conductor tracks 9 which essentially extend in their longitudinal direction and which with their ends are soldered to the connecting elements 1 or solder pins 9 of the plug-in connector 6. The plug-in connectors 6 are screwed to the contact component 3 by means of spacers 11.

The dot-dashed lines in Figure 2 show the conductor foil 5 with the plug-in connectors 6 before the bending-over. In this position, the solder pins 11 extend in the same direction as the connecting elements 1, constructed as insulation-displacing terminals, and can be connected jointly with these to the conductor foil 5, for example by flow soldering.

The contact components 3 are attached at the rear to a common rail 12 which is mounted to a holding angle 13 of a distributor rack.
