SU354574A1 - ELECTRONIC KEY - Google Patents

Description

The invention relates to the field of no-tagged .co-mmutations, namely, electronic contacts based on the Hall effect, and can be used for (K01Mutro, VA, telemechanics, telemetry and digital information signals.

The well-known electronic keys made on the basis of the .eff, Hall effect with two pairs of leads consume a large amount of energy from the current source.

The purpose of the invention is to reduce the energy consumption from the current source Unval yugze chain.

For this, the electronic key contains two horseshoe-shaped cores made of a material with a rectangular hysteresis loop with inserted | Between the end: many HaiCTaiBKs of a magnet of dc material, IB air gap where the semiconductor -plate is located, and the control windings are made in two sections, stirring on cores.

The drawing shows a diagram of an electronic key.

In the air gap of two inserts / of magnet magnet (the material is placed plate 2 (film) of semiconductor material, I | Meyush, and two pairs of terminals. One pair of terminals 3 is connected to the power source 4, and the other 5 - to the receiver 6 signals.

Mounts / are located at the ends of two horseshoe-shaped cores 7 made of a material with a rectangular hysteresis loop, on which sections S and 901 windings are located, connected to pulsed current source 10 of the control unit and its chain. The number of winding sections may be more than two.

The circuit works in the following way.

By applying current to the winding section, both cores 7 are magnetised in one direction but the circumference, i.e., the north lolus of one is in contact with the south pole of the other. In this case, the magnetic fluxes from the chain of cores-7 to the circuit of nastavka 1 do not branch because the magnetic resistance of the value is high due to the presence of an air gap. In this case, the semi-conductor plate 2 (film) is not penetrated by a magnetic field, which means the absence of energy transfer from outputs 3 to output 5 (from input to output). | When serving in one of the sections 8 nl 9

the impeller windings, nonconvertible, its core 7 in the opposite direction, the north and south poles of both cores 7, are in contact with each other — single-handedly, with all of them moving under its action saturation. In this case, the tulip-vodpikova plate 2 (p.nka) is penetrated by a magnetic field, which means the presence of energy transfer from pins to pin 5 (from input to output). Thus, the control level in the control circuit is consumed only at the moments of switching.

Present Invention

The electronic key, executed on the basis of the Hall effect with two pairs of terminals,

characterized in that, in order to reduce energy consumption, from the current sources of the control circuit, it contains two horseshoe-shaped cores made of material with a 1Pr | Mogical loop of hysteresis with CO inserted between the ends of the Astormatic, magnet of a soft 1M material, in a KOTOpbix air gap there is a semiconductor 1Ba (Plate, and the control windings are made iB of the form of two sections, located on the core and x.
