SU1309115A1 - Relay based on hermetically-sealed ferreed switches - Google Patents

Abstract

This invention relates to high frequency switching devices. The relay allows to increase the separation between the input and output in the on state by introducing into the known relays an additional two reed switches, the switching contacts of which serve as relay outputs, the disconnecting contacts connected to the same contacts of the first and third reed switches, and the closing contacts and the opening contact of the second reed switch connected to the screen. 1 il.

The invention relates to electrical engineering, in particular to switching elements dp; coordinate antenna switches, and can be used to switch various high-frequency low-current circuits.

The aim of the invention is to increase the isolation between the inputs and outputs of the relay in the on position,

The drawing shows a diagram of the connection of reed switches.

The relay consists of five sealed switching reed switches 1-5, a control winding 6, a screen 7 with four high-frequency outputs 8-11. The reed switches have contacts 12 and 13 of a ferromagnetic material and contact 14 of a non-ferromagnetic material. Contacts 12 are closing 13 - switching, 14 - opening contacts. Contacts 14 reed switches 4 and 1, as well as reed switches 3 and 5 are interconnected. Contact 12 of reed switch 1 is connected to contact 13 of reed switch 2, contacts 12 of reed switches 2 and 3 are interconnected. , the contacts 12 of the reed switches 4 and 5 and the contact 14 of the reed switch 2 are connected to the screen 7 o All the reed switches are located inside the control winding 6. The switching contacts of the first and third reed switches are connected to the input terminals of the relay, and the switching contacts of the fourth and fifth are connected to the output terminals of the relay

The relay works as follows

In the off position of the relay, Toe in the absence of a controlling magnetic field, the spring contacts 13 in all the reed switches are pressed to the contacts 14, the High-frequency signal received at the inputs 9 and 10 pass through the contacts 13 and 14 of the reed switches 1.4 and 3.5 on outputs respectively 11

In this way, it is possible to build a coordinate switch with cutting loops by connecting the high-frequency outputs of one relay to the inputs of the next relay. A constant voltage is applied to turn on the relay to winding 6. Under the action of the magnetic field of the winding 6, the contacts 13 in all reed switches are closed with contacts 12, circuits 8 and 9, and also 10 and 11 are opened, and the circuit between outputs 9 and 10 is closed, thus all unused loops are disconnected and the outputs 8 and 11 on the screen.

The proposed relay can be implemented on high-frequency reed switches such as MK, KEM, etc.
