Abstract

The invention relates to a single-pole double throw high-power coaxial relay. An electromagnetic system (1)is fixed on a contact system (3) through an upright post (4); an armature iron part (2) is arranged on a cover plate (5) of the contact system (3) and below the electromagnetic system (1); a closed hood (6)is fixed above the contact system (3); and the electromagnetic system (1), the armature iron part (2) and the cover plate (5) are positioned in the closed hood (6). In the invention, the armature iron part installed on the cover plate of the contact system is driven under the action of the electromagnetic system to rotate, so as to push a push rod of the contact system, and a moveable spring moves freely to complete the contact conversion in the depth direction of a cavity body under the action of the push rod and a reset spring. The invention can work on microwave frequency band with direct current, has very low insertion loss and radio-frequency power transmission capability above 3KW, and is suitable for the occasions, such as high bandwidth, low loss, and high power.

Description

technical field [0001] The invention relates to a single-pole double-throw high-power coaxial relay. Background technique [0002] The maximum RF power transmission capacity of existing coaxial relays does not exceed 3KW, and coaxial relays with larger capacity are generally driven by motors, and the action (operation) time of coaxial relays driven by motors can reach more than 1S or even longer. At present, there is no action time in the market that is only tens or hundreds of milliseconds and has a magnetic holding (self-locking) function. The radio frequency interface is a high-power coaxial connector, and the radio frequency power transmission capacity can reach tens of kilowatts or even higher. High power coaxial relay products with point bandwidth from DC to the highest operating frequency. Contents of the invention [0003] The technical problem solved by the present invention is to design a single-pole, double-throw high-power coaxial relay. Its electromagnetic sy...
