The invention relates to an electrical connection device with a plurality of intersecting input and output lines which are electrically isolated from one another and which are switched by means of a switching device are optionally connectable to each other, with each output line at the same time no longer can be connected as an input line.

One known connector (U.S. Patent 2,796,473) has an arrangement that is operable in a similar way. However, this known device has the disadvantage that the contact system only an insufficiently secure contact is guaranteed. There are only at each intersection Rails are provided which are brought into sliding contact with a sliding member which is connected to a Plate is connected, which is brought into contact with the other rail. In this version are two contact surfaces available, which can give rise to malfunctions.

Furthermore, a similar connecting device is known (German Auslegeschrift 1 011 032) in which the electrical connection at each intersection of an outgoing line with an incoming line can be produced by a rotary switch. Socket wrenches are required to operate the rotary switches provided, of which only one in the switch of a single outgoing line in the Off position can be inserted. However, this lock is very unsafe because the socket wrench is lost go or through reproduction several times or through damage to the pass openings in the case of wrong ones Outgoing lines can be plugged in.

In contrast, the electrical device according to the invention is characterized in that for a microswitch is provided at each crossing point of the input lines with the output lines and above that an insulating block is arranged so as to be displaceable in slide rails, in which an actuating plunger for selecting and actuating one microswitch each is arranged is guided along each of the output lines.

By arranging a microswitch for each crossing point, according to the invention much more reliable contact is achieved. By guiding the actuating tappets in slide rails a simple and safe locking is achieved.

F i g. 3 shows a plan view of the construction according to FIG.

Referring to FIG. 1 there are four input lines 7, 8, 9, 10 and four output lines 11, 12, 13, 14, the input lines and the output lines normally being non-electrical are connected to each other. At each intersection of an output line with an input line, a microswitch is arranged, one of which Pole is connected to the output line and the other pole of which is connected to the input line. Four actuating tappets 15,16,17,18 are slidably disposed in a direction parallel to the output lines and operable to establish electrical connection between an input line and an output line via the microswitch in question. Because the actuating plunger only works in one direction are slidable parallel to the output lines, each input line can be connected to a number of output lines can be connected, however, an output line cannot contain more than fed from an input line. Therefore, in the drawing, the input line 7 is with both output lines 11 and 13 connected.

The physical structure of the connecting device according to the invention is shown in FIG and 3 shown. A base plate 21 carries a plurality of parallel longitudinally extending channels 22 in which insulating blocks 23 are slidably arranged. Each block 23 carries an actuating plunger 24, the axial movement of which is limited by a stop 25 which is arranged in the block 23 and engages a slot in the plunger 24. the

Claims (1)

Blocks 23 are covered with a plate 26 through which the plungers 24 extend upward. On its underside, the base plate 21 carries a plurality of microswitches 27. These switches are arranged in longitudinal rows below the channels 22 and are also aligned in transverse rows, as shown in FIG. 3 can be seen. Each switch 27 includes an input terminal 28, an output terminal 29, and a conductive spring plate 30 which, attached to terminal 28 , is not normally in contact with terminal 29 . The leaf spring 30 is movable by a rotatable isolation lever 31 operated by a ball 32 to be brought into contact with the terminal 29. A portion of the ball extends outwardly from the housing and is located under the channel 22 in question. The terminals 28 of the switches in the transverse rows are interconnected to form an input line. Such an input line is shown in FIG. 2 ao shown. The terminals 29 of the switches in the longitudinal rows are connected together to form the output leads, three of which are shown in FIG. 2 are shown. By appropriately positioning the insulating blocks 23 , each output line can be connected to each input line, but only one input line can be connected to any output line. For some applications, the input and output lines can be exchanged, so that the actuating tappets are displaced parallel to the input lines. Claim: Electrical connection device with a plurality of crossing input and output lines, which are electrically separated from one another and which can be optionally connected to one another by means of a switching device, each output line being connectable to not more than one input line at the same time, characterized in that for each crossing point one of the input lines (7 to 10) with one of the output lines (11 to 14) a microswitch (27) is provided and an insulating block (23) , in which an actuating plunger (24) is arranged for selection and actuation each, is slidable in slide rails (22) a microswitch (27) is guided along one of the output lines (11 to 14).
