Technical field
The utility model relates to a kind of isolator, particularly relates to a kind of waveguide isolator.
Background technology
The separate cavities of existing traditional waveguide isolator is whole chamber, and inside cavity poor flatness, size are difficult for guaranteeing, very inconvenience is installed, and efficient is low, and error is big, causes the inconsistent situation of installing easily.Existing waveguide isolator; Comprise upper cavity and lower chamber, metal matching blocks and following metal matching blocks on also correspondence is provided with respectively on the opposite face of said upper cavity and said lower chamber, said microwave ferrite is clipped in the said metal matching blocks and said down between the metal matching blocks that goes up; Said microwave ferrite and said going up between the metal matching blocks are provided with deielectric-coating; Be provided with down deielectric-coating between said microwave ferrite and the said following metal matching blocks, absorber is arranged in the groove of upper cavity, also is respectively arranged with the chamber, magnetic field on upper cavity and the said lower chamber; Said magnetic field is provided with permanent magnet in the chamber; Said permanent magnet is corresponding respectively to be encapsulated in said upper cavity and the said lower chamber through upper cover plate and lower cover correspondence, and upper cavity and lower chamber fix through the flange hole of four standards, and alignment error is bigger.
Because the defective that above-mentioned existing waveguide isolator exists, the design people actively studies innovation, in the hope of founding a kind of waveguide isolator of new structure, makes it have more practicality.
The utility model content
The main purpose of the utility model is, overcomes the defective that existing waveguide isolator exists, and a kind of waveguide isolator of new structure is provided; Technical problem to be solved is to make its efficient height that is located by connecting; Locate more accurate, thereby be suitable for practicality more, and have the value on the industry.
The purpose of the utility model and solve its technical problem and adopt following technical scheme to realize.Waveguide isolator according to the utility model proposition; Comprise upper cavity, microwave ferrite, absorber, chamber, magnetic field, match with ceramic post, following metal matching blocks, go up metal matching blocks, following deielectric-coating, go up deielectric-coating, upper cover plate and lower cover; Said upper cavity and said lower chamber are fixed through self draw-in groove and groove; Correspondence is provided with a plurality of bolts hole respectively on said upper cavity and said lower chamber, through bolt said upper cavity and said lower chamber is linked into an integrated entity.
Aforesaid waveguide isolator, wherein, said microwave ferrite is the anti-power ferrite of the nickeliferous TT2-101/3000 of triangle cylindricality.
Aforesaid waveguide isolator, wherein, said deielectric-coating down and last deielectric-coating are triangle PTFE medium film.
By technique scheme, the utility model waveguide isolator has advantage at least:
Not only pass through self draw-in groove and groove positioning and fixing between upper cavity of the utility model and the lower chamber; But also on upper cavity and lower chamber respectively correspondence be provided with a plurality of bolts hole, connect said upper cavity and said lower chamber is integral the formula structure through bolt.
In sum, the waveguide isolator of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
Description of drawings
Fig. 1 is the structural representation of waveguide isolator of the present invention.
Among the figure: 1, lower chamber; 2, upper cavity; 5, microwave ferrite; 6, absorber; 7, the first square draw-in groove; 8, the second square draw-in groove; 9, square groove; 10, bolt hole; 11, boss; Chamber, 12 magnetic field; 15, bolt; 31, following metal matching blocks; 32, go up metal matching blocks; 41, following deielectric-coating; 42, go up deielectric-coating; 131, first permanent magnet; 132, second permanent magnet; 141, upper cover plate; 142, lower cover.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the embodiment of the utility model specify as after.
As shown in Figure 1; Waveguide isolator; Comprise upper cavity 2, microwave ferrite 5, absorber 6, chamber, magnetic field, following metal matching blocks 31, go up metal matching blocks 32, following deielectric-coating 41, go up deielectric-coating 42, upper cover plate 141 and lower cover 142, upper cavity 2 is fixed through self draw-in groove and groove with lower chamber 1, and correspondence is provided with three bolts hole 10 respectively on upper cavity 2 and lower chamber 1; Through bolt 15 upper cavity 2 and lower chamber 1 are linked into an integrated entity; The waveguide isolator of the utility model is not only through self draw-in groove and groove positioning and fixing between upper cavity and the lower chamber, but also on upper cavity and lower chamber respectively correspondence be provided with a plurality of bolts hole, connect said upper cavity and said lower chamber is integral the formula structure through bolt; Install more conveniently, it is more accurate to locate.
Another innovative point of the utility model is that microwave ferrite 5 is the anti-power ferrite of the nickeliferous TT2-101/3000 of triangle cylindricality, and following deielectric-coating 41 is a triangle PTFE medium film with last deielectric-coating 42.
The above; It only is the preferred embodiment of the utility model; Not being that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment exposure as above, yet is not in order to limit the utility model; Anyly be familiar with the professional and technical personnel; In not breaking away from the utility model technical scheme scope, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents of above-mentioned announcement capable of using, be the content that does not break away from the utility model technical scheme in every case;, all still belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
