Description
Technical field
The utility model is related to a kind of cavity more particularly to a kind of cavitys applied to path filter.
Background technology
Several waveguide channels are offered on the cavity of existing path filter, however, the waveguide channels in existing cavity
In the presence of the problem of unreasonable is arranged, the normal work of path filter is thus affected.
Therefore, in view of the above-mentioned problems, it is necessary to propose further solution.
Utility model content
The purpose of this utility model is to provide a kind of cavity, to overcome the deficiencies in the prior art.
To realize above-mentioned purpose of utility model, the utility model provides a kind of cavity, is applied to path filter, bag
It includes：Substrate, several waveguide channels being hollowly arranged on the top surface of the substrate；
A part in several waveguide channels is distributed in one side of the top surface, its in several waveguide channels
Remaining part point is symmetrically distributed in the another side of the top surface, and any waveguide channels include：First straight line passage, bending are logical
Road, second straight line passage and U-shaped channel, the first straight line passage include first segment and second segment, the one of the first segment
End is connected by the second segment with the bending channel, and the bending channel passes through the second straight line passage and the U
Shape passage is connected.
The improvement of cavity as the utility model is provided with the first recess, opposite side on the one side side of the substrate
The second recess is provided on opposite side.
The improvement of cavity as the utility model, the width on described substrate one side are less than the width of the substrate another side
Degree.
The improvement of cavity as the utility model, the quantity of the waveguide channels is 8, and one side of the top surface is distributed
There are four waveguide channels, and four additional waveguide channels are distributed in another side.
The improvement of cavity as the utility model, the waveguide channels are integrally machined shaping by machining.
Compared with prior art, the beneficial effects of the utility model are：The cavity of the utility model passes through to waveguide channels
Arrangement is optimized, which obviates and makes a difference between waveguide channels, and then the normal work of path filter has been effectively ensured.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments described in the utility model, for those of ordinary skill in the art, is not making the creative labor
On the premise of, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the stereoscopic schematic diagram of a specific embodiment of the cavity of the utility model.
Specific embodiment
The utility model is described in detail in shown each embodiment below in conjunction with the accompanying drawings, but it should explanation,
These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works
Energy, method or equivalent transformation or replacement in structure, belong within the scope of protection of the utility model.
As shown in Figure 1, the cavity of the utility model is applied to path filter, specifically, the cavity includes：Substrate 1,
Several waveguide channels 2 being hollowly arranged on the top surface of the substrate 1.
The first recess 11 is provided on the one side side of the substrate 1, it is recessed to be provided with second on the opposite side of opposite side
Fall into 12.Wherein, first recess 11 and the described second 12 asymmetric settings of recess.In this way, the width on described 1 one side of substrate is small
Width in 1 another side of substrate.
A part in several waveguide channels 2 is distributed in one side of the top surface, in several waveguide channels 2
Rest part is symmetrically distributed in the another side of the top surface.Wherein, there is certain interval between adjacent waveguide channels 2.Such as
This, by the way that waveguide channels are optimized with arrangement, which obviates and makes a difference between waveguide channels, and then passage has been effectively ensured
The normal work of wave filter.In one embodiment, the quantity of the waveguide channels 2 is 8, and one side of the top surface is distributed
There are four waveguide channels 2, and four additional waveguide channels 2 are distributed in another side.
Specifically, any waveguide channels 2 include：First straight line passage 21, bending channel 22, second straight line passage 23
And U-shaped channel 24.Wherein, connection is kept between each passage, and any waveguide channels 2 are integrally machined by machining
Type.Specifically, the first straight line passage 21 includes first segment and second segment, and one end of the first segment passes through the second segment
It is connected with the bending channel 22, the bending channel 22 passes through the second straight line passage 23 and 24 phase of U-shaped channel
Connection.
In conclusion the cavity of the utility model which obviates waveguide channels by the way that waveguide channels are optimized with arrangement
Between make a difference, and then the normal work of path filter has been effectively ensured.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
