A transmission mechanism for a microwave switch

Abstract

The invention discloses a transmission mechanism for a microwave switch. Driving plates are J type spring plates and include long sides and short sides; the long sides and the short sides are connected based on arc structures; lug plates with through holes are arranged on the short sides and the short sides are connected to a cover plate by support bolts; and the long sides are arranged between an armature group and driving rods. A permanent magnet, a magnetic conductive plate, and iron cores of a left coil group and a right coil group form an enclosed magnetic circuit for generate magnetic forces; and the generated magnetic forces are applied to the armature group. An armature has a V-shaped structure; the armature and a carrying and touch body are fixedly connected; protruding lugs in contact with the driving plates are arranged at the lower sides of the two ends of the armature, so that the strokes of the driving rod can be enlarged. According to the invention, the strokes of the driving rods can be effectively enlarged; and on the premise that the effective stroke is realized, the appearance dimension of the product and the product complexity are reduced.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a transmission mechanism for a microwave switch, which belongs to the field of mechanical design. Background technique [0002] The main function of the mechanical microwave switch for aerospace is to realize the transmission and switching of the microwave signal path of the satellite system. It is a device that uses vacuum isolation and switches microwave signals through mechanical actions. It is an important part of the microwave communication system and an important, necessary and irreplaceable key component of the microwave link in the entire microwave system. Its main function is to select microwave signal routing and improve the flexibility of system function combination; second is to build a microwave transmission loop to back up microwave equipment and stand-alone devices with high failure rates to improve the reliability of the entire system.

Problems solved by technology

[0003] The driving piece used in the existing mechanical coaxial microwave switch is a planar driving piece. This type of driving piece is fixed on the armature group. The driving piece drives the driving rod and the reed to move downward with the rotation of the armature. The structure of the driving piece The limitation of the reed stroke is limited, and it is difficult to meet the transmission requirements of the large stroke of the high-power microwave switch.
