Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0038] The invention discloses a single spiral tube type changeover switch, which comprises a relay assembly, a reed transmission mechanism and a transmission line assembly.
[0039] Such as Figure 3a and Figure 3b As shown, the relay assembly includes core assembly 1, washer 2, insulating gasket 3, pad reed 4, upper end cover 5, snap reed 6, sleeve II7, coil assembly 8, top ring 9, magnetic steel 10, coil Guard sheet 11 and coil reed 12.

Abstract
The invention provides a novel single-spiral-tube type change-over switch. The switch comprises a relay assembly, a reed transmission mechanism and a transmission line assembly; the relay assembly comprises an iron core assembly, a gasket, an insulation spacer, a pad reed, an upper end cover, a clamping reed, a sleeve II, a coil assembly, a push ring, a magnetic steel, a coil protection sheet and a coil reed; the iron core assembly is successively provided with a push rod, an iron core, a clamping reed, a pad reed and a lower end cover from top to bottom; the reed transmission mechanism comprises a main reed assembly, a movable reed mounting plate, movable reeds and screw studs; and the transmission line assembly comprises four reed assemblies, four radio-frequency connectors and a radio-frequency cavity, and radio-frequency reeds are disconnected with the radio-frequency connectors in the absence of an external force. Only one iron core assembly drives a main reed and the movable reeds to achieve switching of the change-over switch, and flatness of the main reed and flatness of the movable reeds are easy to guarantee; and on one aspect, electromagnetic holding forces and drive forces of various paths are almost the same, and, on the other aspect, probability of change-over switch failure caused by a movement assembly failure is greatly reduced.
Description
technical field [0001] The invention relates to the field of switches, in particular to a single spiral tube type changeover switch. Background technique [0002] In recent years, both military electronic equipment and civilian electronic products have shown technical characteristics such as knowledge-intensive, high-tech content, high degree of integration, and complex structure, which has brought great difficulties to the testing and maintenance of equipment and products. This kind of demand, automatic test system (abbreviated as ATE) arises at the historic moment, it has the advantages of automation, integration and rapid measurement and diagnosis. The microwave switch is an important microwave device to realize ATE automation and plays a role of signal routing. Therefore, the reliability of the microwave switch directly determines the performance of the ATE. The transfer switch is a kind of microwave switch, such as figure 1 As shown, the transfer switch is a four-port...
