The invention discloses a linear type waveguide switch which consists of a stator casing, an active cell assembly and two groups of drive assemblies. The active cell assembly consists of an active cell casing, a straight waveguide tube, a bent waveguide tube and two pieces of magnet steel. The straight waveguide tube and the bent waveguide tube are installed in a cavity of the active cell assembly, the two pieces of magnet steel are respectively installed on two end faces of the active cell assembly, and dovetail grooves are processed on two sides of the active cell casing. Each group of drive assemblies consists of a stator cover, a circuit board and a solenoid, wherein the solenoid is fixed on the stator cover, and the circuit board is installed in the solenoid. The two groups of drive assemblies are installed at two ends of the stator casing, two sides of an inner wall of the stator casing are provided with rams for installing active cell assembly, and a waveguide window for forming a waveguide channel together with the straight waveguide tube or the bent waveguide tube in the active cell assembly is processed on the stator casing. The linear type waveguide switch is simple in structure, light in weight and high in switching speed.
Description
technical field [0001] The invention relates to a linear waveguide switch, in particular to a linear single-pole double-throw or double-pole double-throw waveguide switch, which belongs to the field of electromechanical technology. Background technique [0002] As a mechatronic component, the waveguide switch is mainly used for the selection of the microwave signal transmission path, the on-off of the waveguide transmission energy or the switching between channels. It is widely used as a backup switch for radar and communication transmitters with high power output. At the same time It is also widely used in microwave launch equipment and microwave measurement and control projects of satellite communication systems. It is often used to realize the 1:1 backup of the core microwave equipment or the switching between the antenna and the unloading channel on the microwave power signal. It is one of the key components of the satellite signal transmission system. [0003] The trad...
