As shown in Figure 1 to Figure 3, the radio-frequency devices of cavity 200 that the present embodiment is provided, including with multiple enclosure walls 210
Cavity 200, cavity 200 is externally provided with the wiring groove 230 defined by enclosure wall 210 and for installing transmission cable 100, transmission cable
100 outer conductor is fixedly connected by scolding tin 300 with wiring groove 230, and the filling of covering scolding tin 300 is also formed in wiring groove 230
Sealing 400, enclosure wall 210 is provided with the anticreep locating part for being used for limiting casting glue 400.
The radio-frequency devices of cavity 200, it is simple in construction, transmission cable 100 is being fixed on wiring groove 230 using scolding tin 300
On the basis of interior, by that in the outer setting casting glue 400 of cavity 200 and anticreep locating part, can prevent that it is same that scolding tin 300 from aoxidizing
When play the double effectses for greatly improving the structural reliability for constraining in transmission cable 100 in wiring groove 230, it is to avoid scolding tin
300 insecure, poor reliability and situation about easily being released by factors such as environment, external force, in the long-term use of the radio-frequency devices of cavity 200
During can greatly lift intermodulation index, improve the stability of electric property, reduce potential safety hazard, be adapted in communication base station day
The popularization and application of line technology field.
Because transmission cable 100 is typically that scolding tin 300 is carried under exterior vibration or pulling force effect from formation wiring groove 230
Enclosure wall 210 peel off and come off and cause to loosen between transmission cable 100 and cavity 200, therefore casting glue 400 is either right
Scolding tin 300 carries out covering sealing or carries out covering sealing to scolding tin 300 and exposed transmission cable 100, can be in contact
The effect for preventing that transmission cable 100 from releasing is reached after fixation.Certainly, it can be covered in for preferably casting glue 400 whole exposed
Scolding tin 300 and transmission cable 100, preferable protective effect can also so be played to transmission cable 100.It should be noted that
Above-mentioned exposed transmission cable 100 and exposed scolding tin 300 refer to the respective surfaces close to the notch end of wiring groove 230.
In actual production, scolding tin 300 often covers the surrounding of transmission cable 100, in this case, it should be appreciated that above-mentioned
400 pairs of exposed scolding tin 300 close to the notch end of wiring groove 230 of casting glue carries out covering comprehensively and seals and contact fixation, without
It can be in contact with transmission cable 100.
Above-mentioned wiring groove 230 can be with " U "-shaped, semicircle, " L " shape or other required shapes.Specifically in the present embodiment
In, wiring groove 230 is generally " U "-shaped to be convexly equipped in outside cavity 200.
Above-mentioned casting glue 400 can using common glass cement or other be suitable to the material applied in radio-frequency devices.
Further, in the present embodiment, at least including two spaced wiring grooves 230, two wiring grooves 230 it
Between form medial launder 240, casting glue 400 is in the medial launder 240, be integrally formed on enclosure wall 210 and scolding tin 300.Such knot
On the one hand structure can play spacing locking effect to casting glue 400 using medial launder 240；Another aspect casting glue 400 can be with
Interconnection structure is formed between medial launder 240 and scolding tin 300, in the premise for the complexity for not increasing the moulding process of casting glue 400
Under overall construction intensity can be made preferable；Therefore, such structure can be improved further between transmission cable 100 and enclosure wall 210
Structural soundness and reliability.In addition, such structure can also make the transmission electricity in two wiring grooves 230 using clad
Cable 100 remains mutually isolated, and radio-frequency devices compact overall structure.
Specifically in the present embodiment, in order to simplify processing and fabricating step and improve integrally-built compactness, anticreep is spacing
Part is a pair of the spacing blocking arms put and extended along the groove sidewall of wiring groove 230 towards inner bending relative with the bottom land of wiring groove 230
211.So spacing blocking arm 211 mainly plays a part of longitudinal spacing to casting glue 400, scolding tin 300 and transmission cable 100, profit
Cross spacing effect can be carried out to transmission cable 100, with the groove sidewall of wiring groove 230 so as to reach simplified anticreep locating part
Purpose.
Further, in the present embodiment, spacing blocking arm 211 is integrally formed with enclosure wall 210 by pultrusion or die casting, with
Simplify manufacturing process, and beneficial to batch production.
Further, the spacing knot of cross-connect between scolding tin 300 and enclosure wall 210 can be made by being additionally provided with wiring groove 230
Structure.Position limiting structure as making the medium of cross-connect between scolding tin 300 and enclosure wall 210, relatively simple be by scolding tin 300 from
Body is served as, i.e.,：Position limiting structure include it is recessed in the appearance tin space 231 in wiring groove 230, and/or, be at least convexly equipped in wiring groove
Jut in 230 groove sidewall（It is not shown）.Holding the setting in tin space 231 can enable part scolding tin 300 during welding enter this
Hold tin space 231, so cause after the solidification of scolding tin 300 the part scolding tin 300 can be stuck in appearance tin space 231 and with formation
The enclosure wall 210 for holding tin space 231 is fixedly connected and is difficult to peel off from wiring groove 230 to come off, and greatly improves solder joint
Fastness and reliability.Above-mentioned appearance tin space 231 preferably in wiring groove 230 it is uniform or it is discrete set, be preferably also arranged at cloth
The groove sidewall of wire casing 230 and the intersection of groove bottom wall., can also be by setting jut when the groove width of wiring groove 230 is larger
To reach the purpose of backstop scolding tin 300, while reaching the purpose for reducing the materials of scolding tin 300.
It should be appreciated that above-mentioned scolding tin 300 refers to the tin material after welding solidification.
Specifically in the present embodiment, cavity 200 is substantially in cuboid, and its periphery has the enclosure wall in four faces
210, two end faces of its longitudinally at least end face does not set enclosure wall 210 with reserved opening, and cavity 200 is internally formed cavity
220, radio circuit 500 is arranged in cavity 220, and above-mentioned radio circuit 500 includes but is not limited to phase shifter circuit, wave filter electricity
At least one of road, power divider circuit, coupler circuit, duplexer circuit, combiner circuit and bridge circuit.Above-mentioned wiring
Groove 230 is at least set in an outside of enclosure wall 210, and the groove sidewall of wiring groove 230 is by any projection outwardly of enclosure wall 210
Extension is formed, the groove bottom wall of wiring groove 230 by four faces enclosure wall 210 any one offer.Basis is penetrated on wiring groove 230
Provided with the through hole at least one insertion to cavity 200 the need for the lead of frequency circuit 500, transmission cable 100 is passed through after the through hole
It is connected with radio circuit 500.The material of cavity 200 is metal, and the pore size of through hole should also be arranged to allow transmission cable 100
Medium pass through so that the inner wire of cavity 200 and transmission cable 100 insulate.
Each technical characteristic of above example can be combined arbitrarily, to make description succinct, not to above-described embodiment
In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance
Shield, is all considered to be the scope of this specification record.
