Electronic switch and method for increasing current flux and preventing contacts from heating and burning

Abstract

The invention relates to an electronic switch and a method for increasing the current flux and preventing contacts from heating and burning. The electronic switch includes two electrode layers arranged in parallel up and down, an insulating layer between the two electrode layers and a lifting extension piece, an upper electrode layer and an insulating layer A movable through hole is opened through, and the movable through hole is insulated in the upper electrode layer; the lifting extension is arranged to align with the movable through hole and electrically connected to the lower electrode layer, and the lifting extension has a guide rod that can move in the movable through hole and The contact head connected to the top of the guide rod, the contact head faces the bottom of the guide rod to form a ring surface that is in electrical contact with the upper electrode layer, and the driving device is used to sink the lifting extension to engage with the upper electrode layer, and the ring surface is connected to the upper electrode layer The outer surface of the layer forms a ring-shaped electrical contact area around the active via, thereby solving the problem of contact heating and burning when the current flux increases.

Description

technical field [0001] The invention relates to an electronic switch for supplying current, in particular to an electronic switch and a method for increasing the current flux and preventing contacts from heating and burning. Background technique [0002] As an on-off device for power supply or signal transmission, the power-off switch can be divided into manual passive switch and programmable electronic switch. The size of the electronic switch can be further reduced and program monitoring can be realized. The existing electronic switches with large current flux generally use Darlington tubes, field sensors or relays. Darlington tubes and field switches are good for close control, but because of chip design, they cannot The power-off isolation effect is poor, and its product stability and reliability are not as good as relays. Although the relay can achieve power-off isolation, the contact area of ​​the two electrodes with elastic clips is uncontrollable and easy to age wh...
