Description

GERMAN

The invention relates to an arrangement with armature contacts arranged in protective tubes for Line switching in telecommunication systems, in particular telephone systems. Such a line through-connection is known to take place in dialing devices and coordinate switches. At the coordinate switches the line inputs and the line outputs are arranged according to coordinates. Your multiple lines form intersection points, which are in the crossbar through contact devices as required be switched through.

In known arrangements of this type, the individual contact devices (armature contacts) are row- and column-wise longitudinal coils are assigned which comprise all armature contacts of a row or column. By energizing a column and a row coil, that armature contact is actuated which is connected to is arranged at the intersection of these two coils. The number of anchor contacts at each crossing point usually corresponds to the number of those to be switched through Lines (veins).

These longitudinal coils each comprising a row or column of several armature contacts are very expensive to manufacture and mount; besides, changing is only one thing Crossing point concerned longitudinal coil not possible or associated with the difficulty that all a plurality of intersection points representing contacts, which includes the relevant longitudinal coil, from the replacement be affected.

Furthermore, relays are known as a plug-in unit in which several are arranged in protective tubes There are armature contacts whose connection ends are led out on one side. This known arrangement requires a base and is therefore complex and expensive. When shading with multiple cables Both coordinates are very close together, so that when using Multiple lines made of bare wire cause great difficulties due to the unilateral lead-out of the connection ends result. In addition, these known plug-in arrangements are prone to failure due to vibrations when used in mobile stations.

It is also known to insert the connection ends of the armature contact into the protective tube before melting it. to interlock against each other to the anchor contacts with the crossing multiple lines in two to be able to peel vertically abutting planes. However, this measure requires use from a special version of the armature contacts arranged in protective tubes.

The invention is now based on the object of avoiding these disadvantages of the known embodiment. It is thereby of an arrangement out of order for coordinate terms

going, which represents a coordinated through-connection network that is a relay or a Coil with armature contacts arranged in Schtitz tubes at each intersection of the two multiple fields and its parts serving for magnetic shielding either column-wise or line-wise get lost.

The invention consists in that the relays or bobbins assigned to each crossing point Columns or rows with approaches at their foot end in a correspondingly shaped cutout their support rail used and are thus fixed immovable in the plane and in their longitudinal direction by acting on the head end, designed as a bracket extensions of the shielding Part of the retaining rail can be held in the cutout of the retaining rail in a resiliently releasable manner and that the protruding on both sides from the protective tube, in each case parallel to each other Flat connecting ends of the armature contacts each jointly in one of the two angles lie between the planes bisecting the coordinates.

According to a further embodiment of the invention, the bobbins are open at the foot end and point to the Front side at the head end slots through which the connection ends of the armature contacts are inserted are. The open foot end of the bobbin is also provided with slots for the other connection ends the armature contacts provided with insulating material covered.

According to a further embodiment of the invention, the slots in the coil body form such an angle to the outer edges of the coils that the

The coil body 1 is arranged, for example, from thermal contacts 2, which is shown in FIG. 6 as being made of plastic material. All incisions and 7 and 7 illustrated embodiment a holding depressions on the bobbin are attached in its longitudinal rail 6, on the bobbin 1 with a larger direction. For this reason only a number of anchor contacts are arranged. Structure of the coil flange 1 'is provided at the foot end and the 55 and mode of operation are similar to the embodiment according to FIG. The armature contacts 2 with conductor 13 (FIG. 5) are not formed from bare wires, their one connection end 2 ". In slots 9 and 11 Coil or printed circuit body in application. The anchor contacts will come at the open foot. For better assembly, the insulating end of the bobbin 1 is at the level of the coil plate 5 to hold the connection ends 2 'in two inflansches V by a plastic sponge 4 in axially engaging comb-like parts 5 and 5 "in the upward direction and in a perpendicular direction The plastic sponge, e.g. made of foam, is supported on an insulating plate 5, 65 to protect the anchor contacts against vibrations between the The bobbin 1 and the retaining protection and the soldering points 2 'are mechanically de-splinted 6 (Fig. 2).

Since for this size the bobbin 1, a pocket 7 of the bobbin 1, which is no longer sufficient for a bracket 8, two brackets 8 ″ must accommodate the rectifier shown, each coil and 8 ′ ″ are provided. A slight single and disengaged body 1 in a corresponding cutout 6 ″ of 70 bar is also guaranteed here.

Since the individual bobbins 1 are magnetic only on one side due to the design of the holding rail 6 are shielded, it is appropriate to use the other coil body sides in a known, not shown Way to shield with a sheet metal cap. These caps are by spring action on the Coil bobbins attachable or held.
