It is known in electrical systems to connect devices to multi-core lines, especially for devices with a movable device cable, via distribution boxes to enable proper wiring. To achieve These distribution boxes are easy to replace and monitor the devices provided with easily detachable contact strips, one of which The strip carries the equipment supply cable, while the other with the wires of the line cable connected is. Such arrangements are found particularly in telephone systems Application, wherein the distribution arrangement is mounted in an auxiliary box of conventional design associated with the telephone set is. In the use of the previous version of the side boxes in line voter systems However, the difficulty turns out that by the incoming and outgoing line end of the line line conditional, several lines under one Contact screw are to be placed, which is essential for maintaining safe operation is to be discarded. Experience has shown, however, that normal supplementary boxes for Telephones on ending lines also for devices of a line line use, so that the task was set to use the existing side boxes without significant structural changes for both To use apparatus types. According to the invention, an additional arrangement for normal additional boxes is therefore made by which will eliminate the defects listed above.

A distributor plate, at whose contacts the incoming and outgoing line ends can be connected to a line cable is designed so that it can be used as an add-on on the contact pins of a normal accessory box using the associated Contact screws can be attached so that when replacing an apparatus It is only necessary to unscrew this distributor plate without interrupting and endangering operation on the line. The connection contacts of the distribution board for incoming and outgoing Lines can be designed with a suitable arrangement that for each line end a special clamping screw can be provided at each contact point. This is advantageously achieved in such a way that each terminal contact from an angular upwardly bent metal strip consists of the two at its free end Contact screws for one incoming and one outgoing line each, while the other End preferably by means of a tubular rivet on the distributor made of insulating material

plate is attached, this type of attachment at the same time the insertion of the for allows the fastening of the distributor plate serving terminal screws. In this way, the great advantage is achieved that additional boxes are more normal and uniform Construction for devices on ending lines also for devices on continuous lines Line lines by placing the distributor plate on the existing arrangement use.

The drawing illustrates the subject matter of the invention using an exemplary embodiment, namely shows Fig. ι a cross section through a supplementary box, Fig. 2 a Top view of a distributor plate, Fig. 3 shows a detail of the distributor plate.

In the additional box α there is an insulating plate c placed on the mounting base b , on which contact pins d are attached. Contact screws c , which can be screwed into it from below, are used to connect the lines leading to the apparatus. A distributor plate / can be placed on the contact pins d , also made of insulating material, the connection points of which consist of tubular rivets g and terminal lugs h held by them. The incoming and outgoing lines i are clamped to these angularly bent attachments by means of screws k. The distributor plate is expediently held on the contact pins by screws m , which can be pushed through the tubular rivets g and can be screwed into the contact pins d from above.

If, for example, it is to be replaced as a result of a malfunction of an apparatus, it is no longer necessary, as before, to detach all incoming and outgoing lines from the contact pins d , after which they are connected and insulated accordingly in order to avoid disruption of operation had to be, but it is sufficient to lift the distributor plate f by loosening the screws m from the contact pins d of the accessory box and remove this together with the device. Through the use of the distributor plate, all the continuous switching connections of this call station remain, so that it is now sufficient to attach another device with a corresponding accessory box, on whose contact pins d the distributor plate is clamped in the same way by means of the screws m , whereby the metallic again Connection via the angle h, tubular rivets g and contact pins d between the switching lines i and the apparatus is established.

Claims (3)

Patent claims: i. Distribution arrangement (additional boxes), in particular for line selection systems the incoming and outgoing lines with the associated one. Lines leading to the apparatus are connected, characterized in that one the incoming and outgoing lines leading distributor plate easily detachable with the contact pins of an accessory box, which is one in telephone systems with lines leading to only one subscriber set each has, is connected, the clamping screws of the contact pins for fastening the distributor plate to serve. 2. Device according to claim 1, 8a, characterized in that the connection points for the incoming and outgoing lines are designed in such a way that they are on the one hand with special Connections for each incoming and outgoing line, on the other hand with tubular rivets for their attachment to the distributor plate and for the same insertion of the terminal screws are provided for fastening the distribution plate go. 3. Device according to claim 2, characterized in that the connection points are bent upwards at an angle, with the ends facing the contact screws for the incoming ones and outgoing lines. 1 sheet of drawings
