Description

The invention relates to a connecting device composed of multiple contact switches, which consists of constructed of sheet metal strips that cross each other at right angles and consist of ferromagnetic material is for telecommunications, especially telephone systems. The invention is based on the object based on creating a connecting device which is simple in structure and manufacture Individual parts of simple shape can be produced, has a multiple free of solder joints, low Requires space and works practically noiselessly.

The connecting device according to the invention is characterized in that the sheet metal strips through Insulating strips are electrically isolated from one another, that the sheet metal strips arranged parallel to one another the one crowd than at entrances, z. B. subscriber lines connectable participants seemed the individual entrances are assigned, while the individual sheet metal strips of the other group are used as connecting rails with the participant rails and with one or two more parallel to these participant rails arranged connecting rails can be optionally connected in an electrically conductive manner, and that the a multiple field forming connections for the speech wires and for control lines of several inputs and the same number of connecting bars as well as an associated connecting bar one above the other or one behind the other arranged levels.

In a further embodiment of the invention, the electrically conductive connection of the subscriber rails takes place and the connecting rails with the respectively associated connecting rails by the action a magnetic field which can be generated in field coils and which is applied to the sheet metal strips forming the subscriber rails resilient tabs arranged on one side have an elastically bending effect and thus the contact causes.

The connection device according to the invention is constructed so that several different inputs assigned multiple fields are arranged next to or one above the other. The other participants provided flaps are enclosed by field coils acting as group coils (e.g. as decade coils), whose field establishes contact between all enclosed subscriber rails with all assigned Can bring about connecting rails.

The selection of which of the inputs prepared in this way with a certain of several outputs are to be connected, is done in such a way that the individual busbars arranged lobes are enclosed by field coils acting as individual coils (e.g. as single coils) are whose field a contact between the associated coil in question Connection device composed of multi-contact switches

Interface rail and one of the connecting rails that can be assigned to the relevant interface rail can cause, so that thereby an electrical connection between a certain Input (e.g. subscriber line) and a certain one of several outputs (connection rail) can be produced. In the drawing, in

Fig. 1 shows a partial view of an embodiment of the invention in axonometric representation;

Fig. 2 shows a view in the direction of the arrow Fig. 1 represents;

Fig. 3 shows an arrangement of a connecting device in a schematic representation for a Telephone system.

The embodiment shown in Fig. 1 in axonometric representation of a connection device according to the invention, in which each point of intersection of subscriber or connection rails with the connection rails are assigned four connection points, two for the speech wires a, b and two for the control lines c, d, shows the construction. The subscriber rails 1 are arranged side by side in such a way that the subscriber fields come to lie next to one another, as shown in the drawing for the subscribers TIl to 7 * 15. The participant rails 1 they are crossing

Connecting rails 2 opposite, which are arranged so that their longitudinal direction with that of the subscriber rails forms a right angle. The subscriber rails 1 and the connecting rails 2 are through Insulating strips 3 electrically isolated from one another.

The subscriber rails 1 carry long resilient tabs 4 on one side, through which short, rigid tabs 5 arranged on the connecting rails 2 face a narrow air gap in the thickness of the insulating strips 3 separated from them. Field coils 6 comprise the resilient tabs 4 of a group of subscriber rails 1 of several adjacent ones Subscriber fields, in the exemplary embodiment shown, those of five subscriber fields. However, another grouping can also be used, e.g. B. a decadic, can be selected. When excited one of the Field coils 6 are all resilient tabs 4 that are enclosed by the relevant field coil, to the opposite short stiff tabs 5 of the connecting rails 2 and so make one electrically conductive contact.

Solder lugs 13 provided on the connecting rails 2 serve special purposes; they can also be left out will.

A specific group of participants is selected from the group of participants by the excitation of a specific individual coil 9 comprising the resilient tabs 4 of connection rails 7, 8 4 of the connection bar 7 assigned to the subscribers with an odd subscriber number or the connection bar 8 assigned to the subscribers with an even subscriber number against the short stiff tabs 5 of the selected connecting bar 2, whereby a specific input is connected to a specific one of several outputs.

In Fig. 3 it is shown how the subscriber rails 1 and the connection rails 7, 8 together With the connecting rails 2 formed solder-free multiple extending through the entire connecting device, so that further, the participants Interface rails 10 assigned with an even subscriber number or the subscribers with an odd number Connection rails 11 assigned to subscriber numbers also have access to subscriber rails 1 via connecting rails 2. Through this it is possible to use any participant connected to the connection device to connect any other participant.
