Abstract

The invention relates to electromechanical switching devices used in electrical engineering, radio engineering, communication technology, radio electronics. The purpose of the invention is to expand the scope by increasing the number of switched circuits. In the initial state, the sources of MDS 12 are not energized, the movable contact electrode (EC) 5 is located opposite any of the stationary CE 9, indicated 12 on the contact pair is open due to the interaction of spring contact parts (CD) 6 with ring-shaped permanent magnets (PM) 4 After applying a current pulse to the sources of MDS 12, located opposite the stationary CE 9 and drunk in pairs and sequentially, a magnetic flux is formed that is perpendicular to the moving axis 2, and crosses the magnetic field PM 4, interacts with it. Under its influence, CE 5 turns around, takes the required position, and CD 6 is attracted to CE 9, a short circuit. After the current pulse is removed from the sources of MDS 12, the QE 9 is demagnetized and the electric circuit is broken, the QE 5 returns to the initial state, in which CD 6 interacts with PM 4.

Description

f

The invention relates to electromechanical switching devices used in electrical engineering, radio engineering, communication technology, radio electronics.

The aim of the invention is to expand the scope by increasing the number of switched circuits.

FIG. 1 shows a multi-contact switching device, a longitudinal section; in fig. 2 - the same, top view.

The multi-contact switching device contains a sealed cylinder 1, a movable axis 2 located therein, a dielectric carrier part 3, two annular constant magnets 4, a movable contact electrode 5 made in the form of a rod permanent magnet and equipped with spring contact parts 6 of magnetically soft a material with an electrically conductive layer 7 and dielectric pads 8 located between the rod permanent magnet 4 and the spring contact parts 5, fixed contact electrodes 9 are made Eny in the form of inserts made of magnet of a flexible material, equipped with dielectric pads 10, covered with an electrically conductive layer 11, and sources of VAT 12, each of which is installed outside the sealed cylinder 1, opposite the stationary contact electrodes 9, and these fixed electrodes 9 are mounted on a dielectric support 3 between the two indicated annular permanent magnets 4, the movable axis 2 is placed in the center of the sealed container 1 perpendicular to its longitudinal axis, and the movable contact the electrode 5 is oriented along the longitudinal axis of the sealed balloon 1 and is rigidly fixed on the aforementioned movable axis 2.

The device works as follows SoM.

In the initial state, the sources of VAT 12 are not energized, the movable contact electrode 5 is located opposite any of the stationary contact electrodes 9, this contact pair is in the open state due to the interaction of spring contact parts 6 with ring-shaped permanent magnets 4.

The magnetic flux Φ arising in this position is equal to

Ф Ф + Ф,

where f, -, the magnetic flux rolling

contact electrode 5; F is a magnetic flux of ring-shaped permanent magnets, is closed and maintains viscous contacts in the initial position.

After applying a current pulse to the sources of MDS 12, located opposite the stationary contact electrodes 9 and washed in pairs and sequentially, a magnetic flux F, directed perpendicularly relative to the moving axis 2, is formed and the magnetic field of the ring-shaped permanent magnet 4 intersects interoperates with it, and since F.F., F, then under its influence the movable contact electrode 5 unfolds, takes the required position and the spring contact details 6 are attracted to the stationary contact electrodes 9, the short and an electrical circuit. After the current pulse is compressed from the sources of MDS 12, the demagnetization of the stationary contact electrodes 9 and the breakdown of the electric circuit of the switched contacts occur, the moving contact electrodes 5 return to the initial state, in which the spring contact parts 6 interact with the ring-shaped permanent magnets 4.

Thus, all contact ps. The conditions are the same.

ensures reliable closing and opening of electrical contacts and extends its scope by switching several independent circuits.
