Description

Known electronic wristwatches using a magnetoelectric ave. vivoda with contactless current interrupter, collected on a semiconductor triode. The clock magnetic system is mobile and mounted on a balance, the pulse coil and the feedback coil are stationary. Practical, the use of such clocks is impossible, since the drive circuits of their balance in the non-contact version do not provide small dimensions of the drive (mainly in height), and with a corresponding decrease in it does not create the necessary magnetic field strength in the gap.

The use of the interturn capacity of coils in the electrical circuit as a factor for locking the blocking made it possible to exclude a significant number of elements from the circuit.

To achieve this effect, a horseshoe-shaped magnetic core embedded in the balance rim of the clock is used in the proposed watch design; Two disk-shaped permanent magnets are fixed at its ends. To create an inter-turn capacitance sufficient to close the blocking, the windings of the coils are laid simultaneously in two wires.

FIG. 1 shows a magnetic system; in fig. 2 - electrical circuit.

The magnetoelectric drive represents a closed magnetic system and an electrical circuit on a semiconductor triode. The power circuit consists of a chemical element with a voltage of 56c.

The magnetic system contains two platinum-cobalt disk-shaped permanent magnets 1, connected by a horseshoe-shaped magnetic core 2 with a bend, which makes it possible to reduce the height of hours.

No. 147146-2. The electrical circuit is an amplifier on semiconductor triode 3 with positive feedback.

When the oscillatory movement of the balance 4 magnetic system intersects the windings of the coils 5 m. 6, combined into a common coil 7.

Induced in the winding coil 5 emf. abruptly opens the semiconductor triode, and a current pulse flows through the winding of the coil 6. The magnetic flux of the winding of the coil 6, interacting with the field of the magnetic system, imparts an energy pulse to the balance 4, due to which a balance oscillates without fading. For the full period of oscillation, the balance receives two pulses.

Structurally, the windings of the coils 5 and b are made in the form of a single flat coil of round shape.

By using the Melswitch capacitance of the magnetic coil as an element of locking the blocking, it became possible to exclude a number of parts from the circuit and thereby simplify the circuit.

As tests of prototypes have shown, the amplitude of balance oscillations is very stable. Batteries with a capacity of 100 magas are enough to power the watch for a year.

The clockwork has a height of 6.25 mm and a diameter of 26.6 mm.
