Description

one

The invention relates to telecommunications and can be used in automatic telephone and telegraph stations.

A multiple coordinate connector is known which contains magnetically controlled contacts and alternating magnets encompassed by the control coordinate windings at the switching points, and a DC generator is connected to the control windings of one coordinate.

However, the known device requires two variable magnets at each switching point of the connector, and these magnets must have exactly the same parameters. In addition, the same restrictions are imposed on the parameters of the magnetically controlled contacts and on the accuracy of the assembly of the magnetic system.

The purpose of the invention is to simplify the design and increase its manufacturability, expanding circuit capabilities, as well as reducing the size and reducing the requirements for the parameters of the control current pulse.

To do this, a generator of alternating damped pulses is connected to the control windings of another coordinate.

In this case, a generator of alternating damped pulses is connected to the control windings of the coordinate perpendicular to the longitudinal axis of the magnetically controlled contacts.

Magnetically controlled contacts are covered by a short-circuited coil, made in the form of a ring of non-magnetic material with high electrical conductivity.

FIG. 1 shows the main elements of the connector design; Fig. 2 is a functional control circuit of a multiple coordinate connector.

The multiple coordinate connector contains a variable magnet 1, covered by the coordinate (Y and X) windings 2 and 3 of the control, respectively, of the magnetic circuit 4 and the magnetically controlled contacts 5.

Magnetically controlled contacts 5 are covered by a short-circuited coil, made in the form of a ring 6 of a nonmagnetic material with high electrical conductivity.

The DC generator 7 is connected to the windings 2 of the Y coordinate of the connector via the scheme 8 for the selection of the windings of the V coordinate. In the same way, through the circuit 9 for the selection of the windings of the X coordinate to the windings of the 3 X coordinates, a generator of 10 alternating decaying current pulses is connected. The windings 3 coordinates X are appendicular to the longitudinal axis of the magnetically controlled contacts 5.

The device works as follows.

When the generators 7 and 1 are turned on, the impedances of the control currents are fed to the selected coordinate windings. Moreover, the amplitude of the DC pulse is chosen in such a way that the state of the variable magnets 1 does not change from their separate operation, and the amplitude of alternating decaying current pulses is chosen so that from their operation individually any variable magnet 1 can be demagnetized. Moreover, due to their joint operation at the selected switching point, the variable magnet 1 is magnetized and the magnetoresur & Contact pins 5 are triggered.

In the direction perpendicular to the longitudinal axis of the magnetically controlled contacts 5, the opposite surfaces of the adjacent switching points have an area larger than in the direction coinciding with the above axis. Consequently, there is the possibility of a strong influence of a single switching point on the neighbor. But after passing alternating decaying current pulses along the coil of a coordinate perpendicular to the longitudinal axis of the magnetically controlled contacts, at this coordinate in the connector there can be no more than one variable magnet in the magnetized state, since all the variable magnets will be demagnetized except for the magnet at the selected switching point . Thus, the influence of the coordinate, on the winding of which alternating control current pulses pass between the adjacent switching points, is small.

All magnetic contacts 5, which lie on the selected coordinates, during the passage of control current pulses through

The windings are affected by a pulsed magnetic field. But at the same time, in a magnetically operated contact, the magnetic flux does not increase to a value sufficient for its operation, since in a ring 6 covering the magnetically controlled contacts 5, an emf is induced proportional to the change in flux. The current flowing through the ring 6 induces a flow directed oppositely to the flow induced by the pulses of the control current. The parameters of the ring 6 are chosen in such a way that the resulting flux does not cause the magnetically controlled contacts 5 to be earned at any operating value of the control current amplitude. After the termination of the control current pulses, the constant magnetic field of the variable magnet 1 triggers the magnetically controlled contacts 5 at the selected switching point.
