Technical Field

The invention relates to the technical field of radio frequency relays, in particular to a contact structure of a radio frequency relay.

Background

The radio frequency coaxial relay is also called as a microwave coaxial relay, and is a radio frequency relay taking a coaxial high-frequency joint as a radio frequency leading-out end, and because microwave signals transmitted by the coaxial high-frequency joint have the characteristics of high frequency, wide frequency band and large information quantity, the radio frequency coaxial relay is widely applied to systems such as multi-channel communication, relay communication, scattering communication, mobile communication, satellite communication, radar systems, navigation systems, electronic countermeasure, measurement and detection and the like in the fields of aerospace, aviation, navigation, communication, military, science and technology and the like, so the operation reliability and stability of the radio frequency coaxial relay are very important.

At present, in a pushing structure of a radio frequency coaxial relay, a push rod generally drives a movable contact spring (movable contact) to make linear motion in a pushing direction so as to realize closing and opening actions between a movable contact and a fixed contact. However, when the movable contact acts, the movable contact and the stop pin can rub against each other, and after the movable contact is used for a long time, a large amount of friction particles can be generated, so that the reliability of the product is influenced.
