Abstract

The invention relates to the field of electrical engineering. The purpose of the invention is to increase the vibration resistance. The magnetically controlled contact contains a movable contact electrode (EC) 2, crimping spherical CE 5 and protrusions 6 on both sides. creates a pressure wave on the protrusions 6. As a result, the mobile CE 2 moves with spherical CE 5, which in turn closes alternately with the stationary CE 3. 1 Cp f-ly, 2 ill. W | SL

The magnetically controlled contact contains a sealed balloon 1j under a sliding contact electrode 2, freely located in a sealed balloon 1, and stationary contact electrodes 3 located in opposite walls of the balloon, stationary contact electrodes 4 located in the ends of a sealed balloon 1, spherical moving contact electrodes 5 On the wall 6 of the sealed container 1, two projections are made inside it.

The device works in the following way.

The control coils are wound on the right and left parts of the cylinder (not shown). When the control signal is applied to the control coil of the right side of the cylinder 1, the right end of the moving contact electrode 2 and the stationary contact electrode 4 installed in the right end of the sealed cylinder 1j become magnetized. supplying an alternating current to the control coil, the right end of the moving contact electrode 2 vibrates by colliding with the fixed contact electrode 4, or, if the magnitude of the controlled the signal is small, the moving contact electrode 2 makes forced bending vibrations not income to a fixed one. The oscillatory motion made by the right end of the movable contact electrode 2 is transmitted in the form of waves to the rest of the movable contact of electrode 2. The waves excited in this way, the passage of the protrusions 6, are pressed into them so that the movable contact electrode 2 begins to move in the right direction .

Spherical movable electrodes 5 perform the role of directing ush, rolling, while reducing the decelerating movable contact electrode 2 th

together with the protrusions in the inner wall of the balloon compresses the mobile contact electrode 2 on both sides, slightly deforming it. The lateral deformation of the movable contact electrode 2, provided by the selection of the diameters of the spherical contact electrodes 5, causes its deflections, which serve as a reliable fixation for the vaporous contact electrodes 5 and do not allow free movement. In addition, due to the slight elastic deformation of the movable contact electrode 2, the spherical contact electrodes 5 are pressed against the end surfaces of the stationary contact electrodes 3 installed in the opposite walls of the sealed balloon 1. As a result of this fixation, when the movable contact electrode 2 is moved to the right side, all spherical contact electrodes 5, closing and opening alternately with fixed contact electrodes 3 in the walls of the cylinder 1 Sufficient the masses of the electrodes, the forces of pressing and the switching process without chattering make it possible to commute large currents. Switched circuits can be connected to the terminals of the fixed contact electrodes 3 located in the walls. The rotation of the MOVING contact electrode 2 around the axis together with the spherical contact electrodes 5 is prevented by means of projections 6 in the wall of the cylinder 1

If it is necessary to move the movable contact electrode 2 to the left, the control coil of the left side of the magnetic spindle contact is connected and the process is repeated.

The proposed device has a high vibration resistance, since large forces are needed to separate the spherical electrodes when they are closed with stationary electrodes in the walls of the balloon.

When removing the control signal, the mobile electrode remains in place of the pressure of the spherical electrodes to the fixed

Offer: 1 D) the magnetic control contact is distinguished by enhanced switching capabilities, since it can be used to switch circuits connected to fixed contact electrodes in the walls and at the cylinder end. In addition, at the ends of the cylinder on the axis, it is possible to introduce two more fixed electrodes, which are closed with movable during stopping in the extreme right or left position.
