Description

one

The invention relates to switching technology, in particular, can be used in automatic telephone and telegraph stations for switching circuits of the spoken path and transmission paths of discrete information.

According to the basic invention, the multiple coordinate connectors contain orthogonal magnetic fields intended to change the magnetization state of the variable magnet at the selected switching point. Known connectors work on the magnetization-demagnetization cycle.

However, the known connectors have limited application due to the insufficient degree of anisotropy.

The aim of the invention is to reduce the requirements for stability of the amplitude of the control pulses.

To do this, two additional windings perpendicular to the coordinate system winding are placed on the variable magnets, while the coordinate and second windings of all switching points are connected in series along one coordinate, and the third windings are connected in series along the other coordinate.

The invention is illustrated in the drawings.

FIG. 1 is a diagram of the design of the crossing point; in fig. 2 is approximate

work program; in fig. 3 is an exemplary wiring diagram for connecting the control windings of the connector as a whole. The crossing point contains the first general coordinate winding 1 (winding X), a magnetizing alternating magnet in the direction of the working flow, orthogonal to the general coordinate winding 2 (winding Y), which creates a destructive magnetic field, perpendicular to the working direction, orthogonal winding 3 (winding XY), which creates a pattern that creates a magnetic field that creates a magnetic field, perpendicular to the working direction, orthogonal winding 3 (winding XY). field perpendicular to the working direction, alternating magnet 4, magnetically controlled contact 5.

The connector is an integrally formed board, the parts of which form individual variable magnets 4 switching points. The material for variable magnets is a low-caracter alloy (or ferrite) with a rectangular hysteresis loop. The system of variable magnets covers the X, Y, and XY coordinate planar windings (see Fig. 2) coofBeTCTseHHo (see Fig. 1)

1, 2 and 3. The windings X.Y (see Fig. 2) 3 (see Fig. 1) are wound individually on each of the variable magnets of the switching points and are connected in series along the corresponding winding X. Connection diagram

The windings according to FIG. 3 it is reasonable to perform with the same number of turns of the windings

YKXY.

The magnetization of the variable magnet at the selected switching point is as follows.

In all three windings of the selected coordinates (corresponding to Y, as well as X and XY), it is better at the same time at time o (see Fig. 2) a current pulse is sufficient to magnetize the variable magnet, while all variable magnets along the selected coordinate X and XY two mutually perpendicular fields act and weakly magnetize them. At this time, all the variable magnets along the selected Y coordinate, except for the point of crossing the coordinates, are magnetized in the perpendicular direction, and thus the variable magnets that were previously magnetized in the working direction lose their magnetization in this direction.

In order to reduce the power required to create the connection, it is rational at the time ti to end the action of the control current pulse in winding X, and the current pulse in

windings XY and Y finish later (fa) for the time of magnetization of the variable magnet, but simultaneously in both windings. In this case, all variable magnets at the selected coordinates will be demagnetized in the working direction (including those magnets that were magnetized earlier), except for the chosen crossing point, where the floor is orthogonal to the magnetizing windings

and XY offset each other.
