Description
Technical field
The present invention relates to electrical equipment, the leading rotor with leaf leading passage particularly on a kind of waveguide switch.
Background technology
Waveguide switch is as a kind of electromechanical integration assembly, be mainly used in switching between the selection in microwave signal transmission path, the break-make of waveguide energy or passage, it is widely used as the radar of high-power output and the change over switch for subsequent use of communication transmitter, in the Microwave emission equipment being simultaneously also widely used in Satellite Communication System and microwave observing and controlling engineering.The switching being commonly used to realize antenna in the 1:1 backup of core microwave equipment or microwave power signal and unloading between passage is one of critical component of satellite-signal emission system.
Waveguide switch is generally rotary structure, primarily of electromagnetic system and navigation system composition.The navigation system of waveguide switch is primarily of leading stator and leading rotor composition, and leading rotor does the rotation of finite angle in the cavity of navigation system, thus realizes the switching of microwave transmission passage.Existing waveguide switch leading rotor is square-section to process arc cavity for micro waveguide row of channels, this type of leading passage generally adopts electric spark formula processing method to be shaped, large, the consuming time length of difficulty of processing, costly, and processing after leading channel surface fineness poor, interchannel insertion loss is comparatively large, thus reduces the microwave transmission performance of waveguide switch entirety.
Summary of the invention
The technical problem to be solved in the present invention is: provide the leading rotor with leaf leading passage in a kind of waveguide switch, overcomes the problem that existing leading rotor large, the consuming time length of difficulty of processing that spark machined arc cavity exists as the technology of leading passage on square-section, leading channel surface fineness costly and after processing are poor.
Technical scheme of the present invention is: a kind of leading rotor with leaf leading passage, it is characterized in that, leading rotor is provided with leaf open leading chamber, leaf open leading chamber comprises the groove on the wall of the main part being formed in leading rotor, and the groove bottom surface be formed in the main part of leading rotor is plane.
Further, also comprise, central fovea sphere, to be recessedly arranged on the cutting face of groove.
Further, central fovea sphere arranges two.
Further, also comprise, central boss, protrude and be arranged on the cutting face of groove.
Further, central boss is arranged between two central fovea spheres.
Further, groove milling is formed on the wall of the main part of leading rotor.
The present invention's advantage is compared with prior art:
(1) present invention employs the micro waveguide row of channels that leaf Open architecture is waveguide switch, can be shaped by Rapid milling, reduce the difficulty of processing of leading passage, shorten processing consuming time, reduce processing cost.
(2) the present invention is relative to arc cavity leading passage, improves the fineness of leading channel surface, and this kind of structure can ensure that the insertion loss of waveguide switch at 40GHz place is to below 0.15dB.

Embodiment
The invention provides the waveguide switch leading rotor that a kind of structure is simple, be easy to processing, the micro waveguide row of channels of this leading rotor is made up of leaf open channel, two place's grooves, central boss and central fovea sphere.
Waveguide switch leading rotor structure of the present invention is simple, and its machining can be completed by milling, need with compared with spark machined with traditional cavity type structure, and light face fineness can significantly improve, and the insertion loss of microwave leading is optimized.
Shown in Figure 1, waveguide switch of the present invention forms primarily of electromagnetic system 1, navigation system 2.
Shown in Fig. 2,4, the traditional leading rotor a ' (shown in Figure 3) in the navigation system 2 of waveguide switch is mainly replaced with leading rotor a of the present invention by the present invention.Leading passage in tradition leading rotor a ' is a curved channel c '.And the feature of leading rotor a in the present invention is to have the two leaf open leading chamber g in place and (so-calledly leafly refers to that being formed as bottom surface is plane, the shape that another side is open), leaf open leading chamber g comprises leaf leading passage c, groove f, central boss d and central fovea sphere e.Particularly, leaf open leading chamber g comprises milling and is formed in groove f on the wall of the main part of leading rotor a, groove f cutting place is plane, there is in plane central fovea sphere e and central boss d, two central fovea sphere e go down in groove f bottom notch, and a central boss d is bottom groove f, protruding between two central fovea sphere e, like this, the space that groove f is formed on leading rotor a becomes leaf leading passage c.
The effect of grooves on two sides is used to harmonic inhabitation reflection, and reduce return loss, improve voltage standing wave ratio performance, the degree of depth of groove and fillet data, through simulation optimization, can meet and realize good humorous wave reflection inhibition in Ka frequency range.Central boss is consistent with grooves on two sides effect, is equally to reduce return loss, but principle is different, and central boss mainly compensates wide waveguide an actor's rendering of an operatic tune of leaf open end, causes at the interval occurrence frequency cut off phenomenon of Ka low-frequency range.Concave spherical surface hole Main Function in central boss is equivalent to a spherical cavity resonator, suppressed the leakage of leaf waveguide cavity axial direction by resonance, reduces insertion loss, improves isolation.
The operation principle of tradition leading rotor as shown in Figure 5, leading rotor a ' does the rotation of finite angle in the cavity of navigation system, two curved channel c ' are communicated with the waveguide mouth of leading stator b, thus realize the switching of microwave transmission passage, and the gap between rotor and stator is h.Operation principle of the present invention as shown in Figure 6, when leading rotor a stable in position time, four waveguide mouths of leading stator b are communicated with into two microwave transmission paths by the open leaf leading passage c in two places, and the gap between rotor and stator is h.The present invention is compared with traditional leading rotor structure, and its microwave transmission function is consistent, but in the present invention, micro waveguide row of channels is easier to processing, and surface smoothness is better, and insertion loss is optimized.
As shown in Figure 7, the waveguide switch insertion loss prepared by conventional arched waveguide cavity as shown in Figure 8 for the waveguide switch insertion loss prepared by leaf waveguide cavity.The insertion loss of visible leaf waveguide cavity in full frequency band is low, and has better planarization.And traditional arc waveguide cavity configuration, insertion loss value poor and can only in a bit of frequency range performance more consistent, the performance optimization of full frequency band can not be realized.
Structure of the present invention is simple, processing charges is lower, microwave transmission insertion loss is better, and application prospect is extensive.
The content be not described in detail in specification belongs to the known technology of professional and technical personnel in the field.
