Abstract

The invention relates to a modularized T-type microwave switch, which comprises a circuit board group, an electromagnetic group, an armature group, a cover plate-armature group and a guide system. The circuit board group is fixed above the electromagnetic group, the electromagnetic group is fixed at the upper part of the cover plate-armature group, the armature group is fixed on a cover plate by an installation shaft, and the cover plate-armature group is fixed on the guide system. The electromagnetic group is formed by three electromagnetic modules; the armature group is formed by an armature, a driving plate, bolts, a fixing plate and the installation shaft; the driving plate is fixed below the armature by the bolts and the fixing piece, and the installation shaft is arranged in the central hole of the armature. The guide system is formed by a base, four coaxial connectors, three long reed groups and three short reed groups; and one group of long reeds and one group of short reeds, which are vertical to each other, conduct the corresponding coaxial connectors simultaneously, so as to form a T-type microwave accessing state. The microwave switch is low in driving power, the electromagnetic system is modularized, the assembly and production difficulty is low, the product structure rigidity is good, and the vibration-resistance and impact-resistance performances of the product are strong.

Description

technical field [0001] The invention relates to a microwave switch, in particular to a T-shaped microwave switch. Background technique [0002] The existing T-type microwave switch is mainly composed of three sets of coils respectively controlling three sets of pressure springs to drive the structure of the microwave channel in the guiding system, such as the microwave switch disclosed in the US patent No. US5281936 and the name "microwave switch". . The electromagnetic group adopts a three-pronged magnetic circuit, the transmission system uses a long piece of compression spring transmission mode, and the guide system adopts single-sided contact. The long piece of compression spring has poor shock and vibration resistance, complex assembly and debugging, and reduces the cost of the entire product. Reliability cannot meet the use requirements in complex situations such as space environments. Contents of the invention [0003] The technical solution of the present inventio...
