Distribution frame for telecommunications, in particular telephone systems

The invention relates to a distribution frame with Terminal strips for the connection of incoming lines and not locally separated from them, but on the same Connection strips arranged on the frame side for the connection of outgoing lines, which connection strips for the incoming lines with the connection strips for the outgoing lines through jumper wires are optionally connected, for Fernir.elde-, in particular Telephone system * !.

In a telephone dialing system there is a large number of structural units in relation to the total number of units that cannot be wired directly to one another, since their interconnection changes with the respective traffic conditions, e.g. when expanding. The connecting lines between such structural units are routed through distributors that are housed in special distributor racks. It is known to connect the inputs of the dialing stage preceding in the direction of the connection establishment or the lines arriving from the outside in the telephone housing to connection strips attached vertically to the distributor, which can be designed, for example, as soldering lines. The 'outgoing from the distributor pipes, for example, _o lead to the following selection stage, v / ground while on the opposite side of the manifold to horizontally arranged in the distribution frame Anschlunslelsten (soldering strips) are connected. The electrical connection between the connection boxes of the incoming and outgoing lines is made with the help of shunting tone

Manufactured to be easily interchangeable.

It is now a distribution frame "known in which all connection strips are located on one side of the distribution frame ", so that such a distribution frame is suitable for installation on a wall. The connection strips are in this distribution frame e.g. for the incoming lines in the upper half of the rack level and arranged horizontally, while the connection strips e.g. for the outgoing lines in the lower half of the rack level,

ψ are arranged vertically. Due to the vertical and horizontal arrangement of the connection strips, the jumper wires, which are usually only laid at the installation site, must be laid vertically and horizontally according to the course of the connection strips used for connecting these jumper wires, for which purpose rod-shaped deflection elements attached to the distribution frame, for example, are used = Another disadvantage of such a distribution frame is that the jumper wires, which are placed vertically on top of each other, usually lead through behind the connection strips if they are to be laid on the shortest route from connection point to connection point.

"have to be threaded, which complicates the wiring work and the jumper wiring is confusing.

The object of the invention is now to provide a distribution frame to create, in which the maneuvering work is facilitated and in which the connection part density can be increased without the clarity is decreased.

According to the invention, this is done in that - the connection strips for the incoming lines and the end strips for the outgoing lines in the same

In a simple manner, it is thus possible to use the preferably vertically one above the other connection points of the contracting connection strips through free and mostly straight insertion of the jumper wires with each other electrically connect to. This and the presence of an additional, horizontal maneuvering channel In any case, a threading of jumper wires through closed jumper channels, for example avoided, and thus the workload for creating a jumper wiring is significantly reduced. Of course int it is possible, through the back-to-back arrangement of such distributors, a bilateral operable To form upright distributors, whereby a routing of these two distributors with one another is possible.

According to a further development of the invention, the connection points of local connection strips used for connecting the jumper wires are located in one plane on the front of the distribution frame. In this way, all follow-up work that occurs during shunting can be carried out according to I3. can solder or glue the jumper pins to solder .

can be, whereby the clarity of the jumper wiring can be improved and whereby the connection points can be moved closer together to increase the connection density.

According to a further embodiment of the invention are the connection strips together with their incoming or outgoing lines attached as prefabricated structural units to the extension arms of the frame. The assembly of the • According to the invention distribution frame is thereby It is much easier that the jumper wires are now in the simple manner given by the invention at the installation site Must be connected and routed in the manner in which they are connected. It is advantageous to have the structural units with a so large number of incoming and outgoing lines; as well as to be provided with appropriate connection points, that almost any expansion of the distribution system at any time can be caught.

In a further development of the invention, the jumper channels by wire connection hooks in at least two; perpendicular to the Frame level subdivided wire guide paths one behind the other. This advantageously makes it possible to the jumper wiring provided when creating the distributor, e.g. into the wiring that is lower in the frame Insert wire guide paths in order to create a special second wire guide path for a subsequent one in this way Change of routing or expansion to be carried out to be kept free. -.

According to a further embodiment of the invention all connection strips aligned in rows with their long edges and their front edges arranged at a distance from one another and form between them a multitude of intersecting, horizontal and vertical marshalling ducts.
