Magnetic latching type solenoid control microwave switch driving system

Abstract

The invention discloses a magnetic latching type solenoid control microwave switch driving system, which mainly comprises an upper coil assembly, a lower coil assembly, a magnetic steel array group, an iron core group and a yoke group, wherein the upper coil assembly and the lower coil assembly consist of upper and lower groups of coils, of which the parameters are the same, and the encircling direction of the current of the upper and lower groups of coils are opposite; the magnetic steel array group comprises a plurality of pieces of block-type magnetic steel which are arranged along the circumference and homopolarly centripetal; the iron core group consists of a transmission shaft and an iron core relatively fixed with the transmission shaft; the magnetic steel array group encircles the iron core; the iron core group passes through the axes of magnetic stele arrays; and yokes covers a whole mechanism. Under the condition that the coils are not powered on, the driving system can keep an upper stable state and a lower stable state of the iron core group; when a pulse signal passes through the lower coils, the iron core group moves upwards from the lower state; when the pulse signal passes through the upper coils, the iron core group moves downwards from the upper state; and the travel change of the iron core group reflects switch on and switch off of a travel control microwave switch of an execution mechanism. The magnetic latching type solenoid control microwave switch driving system has the characteristics of large travel, energy saving, compact structure, small volume and the like.

Description

technical field [0001] The invention relates to a microwave switch drive system. Background technique [0002] Due to its own structural characteristics, the solenoid-controlled microwave switch has the advantage of a larger stroke than the traditional driving method. At present, this kind of switch mostly adopts a suction structure. The action principle of this structure is to put metal movable parts in the energized coil (only one coil). After the coil is energized, the metal parts move in the magnetic field to push the transmission mechanism to move. The original position is restored by the restoring force of the transmission mechanism. This structure requires continuous power supply to the drive coil to maintain the action state, which consumes a lot of power. Due to the high power of the conduction microwave signal, the high-power microwave switch has a large action stroke of the corresponding conduction part, and there is a power-saving requirement in the aerospace en...
