Small dual single-pole double-throw coaxial electromechanical switch

Abstract

The invention discloses a small dual single-pole double-throw coaxial electromechanical switch comprising a control circuit assembly, a relay assembly, a microwave signal transmission channel assembly, and a shell. The relay assembly is formed by combining relay assemblies of two single-pole double-throw switches. The microwave signal transmission channel assembly comprises a cavity assembly and a mounting board assembly, the mounting board assembly is formed by combining mounting board assemblies of two small single-pole double-throw switches, and the cavity assembly is formed by combining cavity assemblies of two small single-pole double-throw switches. The electromechanical switch of the invention adopts a relay assembly combination structure and a microwave signal transmission assembly combination structure, is integrated with two small single-pole double-throw switches which can be regarded as a small switch matrix, and can achieve the functions of a variety of forms of switches. A smaller dual switch is achieved, and the minimum size of the dual single-pole double-throw coaxial electromechanical switch can be 22.2mm*33.8mm*57.2mm.

Description

technical field [0001] The invention relates to the field of electromechanical switches, in particular to a small double single-pole double-throw coaxial electromechanical switch. Background technique [0002] The PXI / VXI bus microwave switch matrix module is the key equipment and core component unit of the miniaturized automatic test system based on the PXI / VXI module to realize the automatic comprehensive test function. With the popularization and application of miniaturized automatic test system based on PXI / VXI bus architecture, it can continue to expand and develop towards the top layer and in-depth direction. The requirements for serialized PXI / VXI bus microwave switch matrix modules are also increasing, requiring higher integration. , smaller coaxial electromechanical switches to fill the gap. The double SPDT coaxial electromechanical switch came into being. [0003] The double SPDT coaxial electromechanical switch has 6 signal input and output ports. The signal inp...
