High-reliability relay for radio-frequency switch

Abstract

The invention relates to a high-reliability relay for a radio-frequency switch. The high-reliability relay comprises a lower cover plate, a long screw, a housing, a coil skeleton, an upper cover plate, an upper end cover, an iron core, a moving column and a coil. The magnetic-conductive-material-based housing and the upper end cover form an enclosed structure to reduce the magnetic leakage; and thus the magnetic energy is utilized to the greatest extent. The moving column is formed by an upper moving column and a lower moving column that are connected by threads and thus an upper insulating magnetic sheet, the iron core, and a lower insulating magnetic sheet are fixed; and the straightness of the moving column is guaranteed by threaded connection. The insulating magnetic sheet and the lower insulating magnetic sheet are able to buffer the impact forces in the presence of the impacts with the upper end cover and the housing; and the impact force of the moving column is cancelled effectively by using a buffer reed, so that noises during relay switching are reduced. An upper linear sliding bearing is in direct contact with the upper moving column and a lower linear bearing is in direct contact with the lower moving column, so that the friction force on the moving column is reduced effectively and thus the switching service life of the relay is prolonged.

Description

technical field [0001] The invention relates to a high-reliability relay for a radio frequency switch. Background technique [0002] The magnetic latching relay is a key component in the radio frequency switch. The moving column in the relay has two position states, one is that the moving column is located at the upper part of the relay, and the other is that the moving column is located at the lower part of the relay. The built-in permanent magnet (magnetic steel) of the relay provides magnetic force for the upper end cover and the outer shell, and the coil is excited by the instantaneous current to generate a magnetic force of opposite polarity to the upper end cover and outer shell on the iron core, so that the moving column fixed with the iron core goes up and down. The action can complete the switching of the two position states. After the instantaneous current on the coil is removed, the magnetic force on the iron core disappears, and the moving column in the relay rem...
