Abstract

The invention relates to electrical engineering. The aim of the invention is to reduce chatter and increase productivity. The movable contact-part (KD) 2 is made with a bent free end 3. KD 5 is made movable and form disconnecting contact pairs. When a control signal is applied, the fixed CD 4 is magnetized and attracts the mobile CD 2. When the control signal is removed, the bent end 3 of the mobile CD 2, returning to the initial position, excites a bending wave, which, propagating, contributes to alternately shorting and opening contact pairs of mobile CD 5. 3 Il.

The invention relates to switching devices and may find application in the design of relays, switches, used in both fixed and mobile equipment.

The purpose of the invention is to reduce chatter and increase sensitivity.

FIG. 1 shows a magnetoelectric contact, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one.

The magnetic contact contains a sealed cylinder 1, a movable ferromagnetic contact piece 2 with a bent free end 3, a pair of stationary ferromagnetic contact pieces 4, which form a closing contact pair with the movable contact piece 2. Movable contact parts 5, made of a non-magnetic material, mounted in the opposite walls of the balloon 1 perpendicular to its longitudinal axis, form between themselves. pair with one another break contact pairs. The movable contact piece 2, except for the bent end 3, is covered with an insulating layer 6 on both sides.

Magnetically operated contact works as follows.

The control coils are wound on the leads of a pair of fixed contact parts 4 (not shown). When a control signal is applied, the stationary contact parts 4 are magnetized and the bent end 3 of the movable contact part 2 is attracted. When the control signal is removed, the bent end 3 of the movable contact part 2, returning to its initial position, excites the outgoing wave propagating in the direction of its consolidation. The wave propagation along the longitudinal movable contact part 2 contributes to alternately opening and closing the permanently closed moving contact parts 5. First of all, the closest ones to the bent one open.

the end of the pair of transverse contact parts 5. In view of the fact that part of the energy dissipates in the material of the movable contact part 2, the amplitude of the bending wave decreases in the contact piece fixing bar 2. In connection with this, the transverse movable contact parts 5 have

closer to the free end of the movable contact part 2. The insulating layer 6 between the movable transverse and longitudinal contact details prevents the occurrence of electrical contact between them. After removing the control signal, the movable contact part 2 is rectified and the movable contact parts 5 are closed.

Formula of invention

Magnetically controlled contact containing a sealed cylinder, movable and stationary contact parts, with a movable and at least

One of the fixed contact parts is installed at opposite ends of the sealed balloon, is made of ferromagnetic material and forms a closing contact pair, while the remaining contact parts are made of non-magnetic material and mounted perpendicular to the longitudinal axis of the sealed balloon in its walls one opposite

another, and. mobile contact

the part is covered with an insulating layer on one side, with the exception of the contacting section at the free end, characterized in that, in order to increase sensitivity and reduce chatter, the free contacting area of the movable contact part is bent perpendicular to the longitudinal axis of the sealed balloon. covered with an insulating layer on the other hand, the contact parts installed in the walls of the sealed container are movable and form in pairs one with the other ontaktnye pair.
