Stepping motor control-based high-power electronic switch

Abstract

The provides a stepping motor control-based high-power electronic switch and aims to solve the problems of small driving force and high requirements for a protection box of a traditional electronic switch. The stepping motor control-based high-power electronic switch comprises an electronic switch main body and a fixed box 8; the electronic switch body comprises an extra-thick current-carrying static contact conductive elastic sheet 1, an extra-thick current-carrying moving contact conductive elastic sheet 2, L-shaped conductive elastic sheet fixing plates 3, a PCB 5 and a plastic base 6. Thehigh-power electronic switch is characterized in that the high-power electronic switch comprises a stepping motor 4 and a Hall element 45; the stepping motor 4 is electrically connected with the PCB 5; the stepping motor 4 is electrically connected with the Hall element 45; the Hall element 45 is electrically connected with the PCB 5; the power source line of the PCB 5 can be electrically connected with a load; the number of the L-shaped conductive elastic sheet fixing plates 3 is at least two; and the two L-shaped conductive elastic sheet fixing plates 3 are fixed on the first surface of theplastic base 6.

Description

[0001] The invention belongs to the technical field of timers, and more specifically relates to a high-power electronic switch based on stepping motor control. Background technique

[0002] Most of the traditional electronic switches are mainly controlled by relays. The volume of the relay is relatively small, so the power is relatively small. Usually, the maximum power of the traditional electronic switch is 2HP (HP is the abbreviation of horsepower, Chinese horsepower). Traditional electronic switches are mainly used to drive loads such as motors. As the load increases, the power requirements for electronic switches are also increasing. When the load increases to a certain extent, traditional electronic switches cannot be driven. Therefore, the load that can be driven by electronic switches is relatively limited. Furthermore, traditional electronic switches are placed directly in the protective box, so the requirements for the protective box are relatively high. Contents o...
