Description

The invention relates to a non-resonant resonant relay and can be applied, for example, for an integral reception method.

Known resonant relays

bass, including the PIO

The multi-vibrator containing several vibrators made of magnetically soft material and elastic elements set to different resonant mechanical frequencies and located in the frame window of the exciting coil, a permanent magnet with magnetic cores to create a bias magnetic field, a system of fixed adjustable contacts and movable non-adjustable subroutine contacts. on each vibrator.

However, in a conventional resonant relay, a long contact time of the vibrators is observed after the signal voltage on the exciting coil has been removed, which limits

send-receive rate tion

The purpose of the invention is the implementation of the method of integrated reception, increasing the term of slaukba and room stability.

For this, near the free ends of each vibrator on a non-magnetic base electrically insulated from the magnetic cores, electro-magnetic brakes of the vibrators are mounted, controlled by a special electronic circuit.

The resonant relay contains an excitation coil I with a frame, inside of which there are vibrators 2 of magnet of a soft material.

5 and elastic elements, each of which is tuned to resonance at a certain frequency. The vibrators are fixed on the base 3 so that their longitudinal axes are located along the axial lines of the magnetic field of the excitation pole. Magnetic cores 4 are located parallel to the plane of the vibrators on two external sides of the excitation coil, closing the magnetic circuit of the permanent magnets 5 through the air gap b in the zone of the free ends of the vibrators. On the vibrators, contact springs 7 are fixed with contacts 8, which are opposed to contact screws 9. Near the free ends of each vibrator on a non-magnetic (for example, brass) insulated with a gasket 10 from the magnetic cores, the ground brakes of the vibrators, each of which consists of the magnet of the soft cup 12, the coil 13, the core with the spring 14 and the adjusting screw 15, the ends of the windings of the electromagnets are led through the sealed insulators 16 to the outer surface of the cover 17. The resonant relay operates a trace in this way. When an alternating voltage is applied to the exciting coil I, an alternating magnetic field arises in it, in which the vibrators 2 are magnetised in accordance with the time direction of the alternating magnetic field and interact with the ends of the magnetic circuits 4 having a constant magnetization. When a periodic change of the polarity of the vibrators, a periodic change in the direction of their interaction with the ends of the magnetic cores occurs. In the case where the frequency of the alternating voltage supplied to the exciting coil is equal to the resonant mechanical frequency of one of the vibrators (or is within the bandwidth of the vibrator), after The one receives the maximum buildup and introduces into the periodic contacting a spring-loaded contact 8 with the contact screw 9, which are the switching elements of the electric A circuit of any device (for example, a decoder) In order to meet the requirements of the integral reception method, any vibrator (or a group of vibrators) is braked by the brakes of the vibrators. Electromagnets deactivating vibrators work as follows. A variable voltage with a frequency equal to the resonance of the echanic frequency of one of the ibrators comes from the amplifier frequency 18 to the resonance of the relay 19. After the working of the vibrating vibrator starts when the contact 8 contacts the contact screw 9, the decoder 20 works and forms the signal of the necessary shape for the terminal devices; In addition, the decoder generates a signal to the control circuit of the electromagnet braking vibrators 21. From this circuit, the signal goes to the corresponding electromagnet of the brake of the vibrator, which dampens the vibrations of the operating vibrator, while the measles with the spring 14 are attracted to the end of the cup 12 and the projecting end of the spring with some force it touches the oscillating End of the vibrator, dampens its oscillations and further holds it in this position until the brake signal is removed. At the time of deceleration of some vibrators, the control circuit may generate a signal for stopping deceleration of other vibrators. The temporal relationship of the electromagnet braking vibrators is determined by the specific circuit of the device that implements the integral reception. SUBJECT OF THE INVENTION A resonant low-frequency sound relay containing several vibrators made of elastic elements and a soft magnetic material tuned to different resonant mechanical frequencies and located in the window of the exciting coil's frame, a permanent magnet with magnetic cores to create a bias magnetic field, a system of fixed adjustable contacts and movable non-irregular spring-loaded contacts on each vibrator, characterized in that, in order to implement the method of integral reception, increase the number houstoychivosti and lifetime, near the free ends of each vibrator in the nonmagnetic electrically insulated from the magnetic cores based reinforced elektromagnignye brake with brake springs on the movable armatures.
