Description
Technical field
The application belongs to microwave-radio technology field, specifically, is related to a kind of attenuator.
Background technology
Attenuator is widely used in microwave radio field, and such as radiofrequency signal is decayed, to prevent stop signal distortion etc.,
Because requirement of the attenuator to radiating is higher, therefore the structure of existing attenuator is unsuitable for being fabricated to the decay of relatively high power
Device.
The content of the invention
In view of this, technical problems to be solved in this application there is provided a kind of attenuator, is fixed and declined by heat-conducting glue
Subtract piece to transmission pole chamber, accelerate radiating, avoid the damage of attenuator.
In order to solve the above-mentioned technical problem, this application discloses a kind of attenuator, it includes transmission pole, had inside transmission pole
There is chamber；The input port and output port of transmission pole both sides are connected respectively；The attenuator being arranged in chamber, attenuator both sides
It is sticked in the groove of chamber, and coated with thermally conductive glue between groove and attenuator；Attenuator and input port and output are connected respectively
The contact pin of port；And it is arranged at multigroup fin of transmission pole.
According to an embodiment of the present invention, in addition to it is respectively sealed between output port, input port and transmission pole
Thermal conductive silicon rubber cushion.
According to an embodiment of the present invention, wherein being connected between above-mentioned contact pin and attenuator by conductive silver paste.
According to an embodiment of the present invention, wherein having preset distance between above-mentioned multigroup fin, preset distance is
8mm。
According to an embodiment of the present invention, wherein above-mentioned depth of groove is 3mm.
Compared with prior art, the application can be obtained including following technique effect：
1）Using chamber groove fixed attenuator, while heat-conducting glue heat conduction, improve radiating efficiency.
2）Thermal conductive silicon rubber cushion seals, water proof and dust proof, while radiating effect is preferable.
Certainly, implementing any product of the application must be not necessarily required to reach all the above technique effect simultaneously.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding of the present application, forms the part of the application, this Shen
Schematic description and description please is used to explain the application, does not form the improper restriction to the application.In the accompanying drawings：

Reference
Transmission pole 10, chamber 20, groove 21, input port 30, output port 31, attenuator 40, heat-conducting glue 50, contact pin 60, dissipate
Backing 70, thermal conductive silicon rubber cushion 80, conductive silver paste 90, preset distance L, depth H.
Embodiment
Presently filed embodiment is described in detail below in conjunction with drawings and Examples, and thereby how the application is applied
Technological means can fully understand and implement according to this to solve technical problem and reach the implementation process of technical effect.
Please also refer to Fig. 1 and Fig. 2, Fig. 1 is the attenuator stereogram of the embodiment of the present application；Fig. 2 is the embodiment of the present application
Attenuator schematic internal view.As illustrated, a kind of attenuator includes transmission pole 10, the inside of transmission pole 10 has chamber 20；Point
Not Lian Jie the both sides of transmission pole 10 input port 30 and output port 31；The attenuator 40 being arranged in chamber 20, attenuator 40
Both sides are sticked in the groove 21 of chamber 20, and coated with thermally conductive glue 50 between groove 21 and attenuator 40；Attenuator 40 is connected respectively
With input port 30 and the contact pin 60 of output port 31；And it is arranged at multigroup fin 70 of transmission pole 10.In the present invention one
In embodiment, attenuator changes circuit signal size by the attenuator 40 of inside, but buffers impedance when attenuator 40 is long,
Easily release amount of heat, if heat distributes not in time effectively, easily cause the damage of attenuator.Therefore, the present invention utilizes
The inside of chamber 20 sets groove 21, by the both sides inlay card of attenuator 40 in the stable peace that in groove 21, can either realize attenuator 40
Dress, it can also produce the convenient radiating in enough spaces of chamber 20.It is tightly connected simultaneously using heat-conducting glue 50, is improving the same of stability
When, efficiently by heat transmission to fin 70, improve radiating efficiency.Contact pin 60 realizes the transmission of variable signal, simple in construction,
It is practical.It is noted that in an embodiment of the present invention, the depth H of groove 21 is arranged to 3mm, and engaging is convenient, thickness
Suitably, convenient processing.
The present invention in one embodiment, in addition to is respectively sealed in output port 31, input port 30 and transmission pole 10
Between thermal conductive silicon rubber cushion 80.Because of output port 31, input port 30 be using threaded connection transmission pole 10, sealing compared with
Difference, space is easily produced, immerse moisture content and dust.Huge heat caused by other attenuator 40 can also pass over, and influence to connect
Performance is connect, thus thermal conductive silicon rubber cushion 80 just can play sealing and radiating effect, improve durability, ensure the normal work of attenuator
Make.
In addition, being connected between the contact pin 60 and attenuator 40 of the present invention by conductive silver paste 90, use when improving contact
Completeness, avoids contact with bad, and conductive silver paste 90 also has higher heat dispersion, practical.
It is noted that as shown in Fig. 2 it is 8mm to have preset distance L, preset distance L between multigroup fin 70,
Test of many times, controls mutual gap, and radiating effect is more preferable.
Some preferred embodiments of the application have shown and described in described above, but as previously described, it should be understood that the application
Be not limited to form disclosed herein, be not to be taken as the exclusion to other embodiment, and available for various other combinations,
Modification and environment, and above-mentioned teaching or the technology or knowledge of association area can be passed through in application contemplated scope described herein
It is modified., then all should be in this Shen and the change and change that those skilled in the art are carried out do not depart from spirit and scope
