Embodiment Construction

[0030] like figure 1 , shown in 2, the present invention takes the single-pole six-throw suction type electromagnetically driven microwave coaxial switch as an example to illustrate, it includes: electromagnetic system 1 and guiding system 2 and signal input unit, the signal input unit is made up of 7 terminal posts 3 .

[0031] The microwave coaxial switch terminal 3 is located on the casing 7, and the electromagnetic system 1 is fixed on the cover plate 8 of the guide system 2 by screws. The housing 7 is fixed on the base 9 of the guide system 2 by screws.

[0032] like image 3 , 5 As shown, the electromagnetic system 1 adopts the suction electromagnetic drive mode, and is composed of 6 electromagnetic devices, 1 upper yoke 11 , 1 lower yoke 12 and 3 pillars 14 . The six electromagnetic devices are arranged in a regular hexagon, and are located between the upper yoke 11 and the lower yoke 12, and the upper yoke 11 and the lower yoke 12 are fixed by three pillars 14 arra...

Abstract

The invention relates to a single-pole multiple-throw suction type electromagnetic driving microwave coaxial switch. The switch comprises an electromagnetic system, guide systems and a signal input unit, wherein the signal input unit consists of n+1 microwave coaxial switch binding posts, wherein n is an integer of more than 2 and less than 7; the microwave coaxial switch binding posts are positioned on a shell; the electromagnetic system is fixed on a cover plate of the guide systems; the shell is fixed on a base of the guide systems; the electromagnetic system is in a suction type electromagnetic driving mode and consists of n electromagnetic devices, an upper yoke block, a lower yoke block and three struts which are arranged into a regular triangle; the guide systems consist of the cover plate, the base and n same guide devices; the n guide devices are sequentially arranged; the n guide systems share the cover plate and the base; and the cover plate is fixed above the base. The drive mode of the switch can be difficultly interfered by environment, and the switch has low coil current and low drive power and saves energy.

Description

technical field [0001] The invention relates to a microwave coaxial switch, in particular to a single-pole, multiple-throw suction type electromagnetically driven microwave coaxial switch. Background technique [0002] Microwave coaxial switches are mainly used in the field of microwave high frequency, which can be automatically controlled by voltage or computer programming, and play the role of signal switching in microwave circuits, transmitting signals from measuring instruments to devices under test (DUT). Most of the existing microwave coaxial switches can only realize the single-pole double-throw function, and the one-to-multipoint signal switching capability has certain limitations. [0003] On the other hand, the control part of the existing microwave coaxial switch adopts the armature structure, that is, the electromagnetic field generated by the coil excitation and the magnetic field of the magnetic steel work together to drive the armature part installed on the co...
