Abstract
The utility model relates to a short circuit plunger of a circular groove waveguide, which is a waveguide element used for circular groove waveguide systems. The short circuit plunger of a circular groove waveguide is composed of a waveguide, short circuit plates and a screw micrometer, wherein, the waveguide is composed of two metal flat plates which are separated by an upper insulation strip and a lower insulation strip; a circular through hole along the direction of the length of the metal flat plates is arranged on the center of symmetry of an end face; the short circuit plates are three metal plates of which the thicknesses is one quarter of wavelength and have identical hollow figures as the end surface of the waveguide; the metal flat plates are arranged on a screw mandrel of the screw micrometer at an interval of one quarter the wavelength. The screw micrometer is fixed to an end cover on one end of the waveguide. The utility model is suitable for being used for transmitting a short millimeter wave and a submillimeter wave.
Description
The utility model is a kind of waveguide component that is used for the circular recess wave guide system, belongs to millimeter wave, submillimeter wave technical field.
The transmission line of microwave band and light-wave band has many researchs, the millimeter wave between this two wave band, and the submillimeter wave wave band is then developed laterly, especially short millimeter and submillimeter region.Short millimeter wave, the novel transmission line of submillimeter wave are all being sought to be suitable in countries in the world at present.In the prior art, short millimeter band also adopts the standard rectangular waveguide usually, but loss is very big; Submillimeter region often adopts beam waveguide, but physical dimension is too huge, and assembling is debugged also very difficult; The rectangular channel waveguide is because it is not easy to be connected and experience difficulties with the gyrotron that can export great power now.Because the energy output device of gyrotron is a circular waveguide.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of waveguide component that uses in the circular recess wave guide system of high-power millimeter wave, submillimeter wave---circular recess wave guide short-circuit plunger that is suitable for transmitting is provided.
The utility model designs according to the circular recess wave guide transmission theory, it is by waveguide, short board and micrometer caliper are formed, it is characterized in that two metal plates that the waveguide employing is separated by upper and lower insulation strip constitute, and have a manhole along the metal plate length direction in the symmetrical centre position of its end face; Short board is that three thicknesss of slab are quarter-wave, shape and the identical metallic plate of the hollow figure of Waveguide end face, and they are by being installed on the screw mandrel of micrometer caliper at a distance of quarter-wave; The micrometer caliper frame is fixed on the end cap of waveguide one end.The turn micrometer caliper can make short board parallel moving in waveguide space, and the distance that moves can be read from micrometer caliper.For the ease of the connection between the waveguide component, on the wall of the other end limit of waveguide, be provided with connecting hole.
The utility model is based upon on the circular recess wave guide basis, compared with prior art, has low-loss, low chromatic dispersion, the waveguide cross-section size is big, and the power capacity of transmission is big, be convenient to and produce short millimeter wave, the gyrotron of submillimeter wave great power is connected and waits the advantage of giving prominence to.The little order of magnitude of the standard rectangular waveguide that its loss ratio is traditional; Cross sectional dimensions is bigger 6～8 times than the standard rectangular waveguide under the same frequency; So the power capacity of transmission is than the big manyfold of standard rectangular waveguide.The energy output device of gyrotron is a circular waveguide, so can change with circular recess wave guide easily, circular recess wave guide provides the energy transform device of function admirable for it.The utility model is one of necessary element of forming the circular recess wave guide transmission system, be particularly suitable for short millimeter and submillimeter region high power transmission, its effect is the short-circuit plunger in existing other various Wave guide systems, for example rectangle short-circuit plunger, circular short-circuit plunger, institute is irreplaceable.
