Description
Technical field
This utility model relates to a kind of high frequency coaxial part, particularly relates to a kind of closed type high frequency coaxial part.
Background technology
High frequency coaxial part, as the one of contact, be electric connector be a core component, be used for transmitting
High-frequency signal, owing to high-frequency signal is easily disturbed, the design of its structure is all succinct, to reduce difference contact
The impedance contrast opposite sex on face.At present, high frequency coaxial part conventional both at home and abroad, substantially by central contact, absolutely
Edge body, outer conductor three part form.As it is shown in figure 1, be existing same shaft member structure, such as need with shaft member to seal,
Generally realize by insulator 7 tight fit or at insulator 7 surface coating, but, by insulator 7
Tight fit or the sealing property of low index can only be realized in the mode of insulator 7 surface coating, and friction tight
Assembling mode is also unfavorable for production and processing.
Utility model content
The technical problems to be solved in the utility model is just to provide a kind of closed type high frequency coaxial part, solves existing
The problem that high frequency coaxial part sealing property is low.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: Yi Zhongmi
Envelope type high frequency coaxial part, including inner wire, outer conductor, the first insulator, the second insulator, inner wire
One end is built in the first insulator, and the other end of inner wire is built in the second insulator, the first insulator
All being built in outer conductor with the second insulator, also include that surface has the sealing of cementability, sealing sets
Putting between the first insulator and the second insulator, the edge of sealing contacts with outer conductor medial wall.
Preferably, sealing includes sealant layer and ceramic ring, and ceramic ring is arranged in sealant layer, seals
One end of glue-line contacts with the first insulator, the other end of sealant layer and the contact of the second insulator, can guarantee that
Can improve sealing property, simple in construction during with the transmission performance of shaft member, ceramic ring is conducive to sealant layer to solidify
Shrink, improve the adhesive property of sealant layer.
Preferably, the vertical axis of sealant layer overlaps with the vertical axis of ceramic ring, can guarantee that sealant layer
Stability, improve sealing effectiveness.
In sum, advantage of the present utility model: having the sealing of cementability by surface, to connect first exhausted
Edge body and the second insulator, and the edge of sealing contacts with the medial wall of outer conductor, can guarantee that same shaft member passes
On the premise of defeated performance does not reduces, improve sealing property, it is possible to according to the same shaft member of different model to sealing
The thickness in portion is adjusted, and Practical Performance is good, relative to the assembling mode of existing gluing close-fitting, improves and adds
Work efficiency rate.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of existing a kind of high frequency coaxial；
Fig. 2 is the structural representation of this utility model a kind of closed type high frequency coaxial part.
Detailed description of the invention
As in figure 2 it is shown, a kind of closed type high frequency coaxial part, insulate including inner wire 1, outer conductor 2, first
Body the 3, second insulator 4, one end of inner wire 1 is built in the first insulator 3, another of inner wire 1
End is built in the second insulator 4, and the first insulator 3 and the second insulator 4 are all built in outer conductor 2,
Also including that surface has the sealing 5 of cementability, sealing 5 is arranged on the first insulator 3 and the second insulator
Between 4, the edge of sealing 5 contacts with outer conductor 2 medial wall, and sealing 5 includes sealant layer 51 He
Ceramic ring 52, ceramic ring 52 is arranged in sealant layer 51, one end of sealant layer 51 and the first insulator
3 contacts, the other end and second insulator 4 of sealant layer 51 contact, and can guarantee that the transmission performance of same shaft member
Time can improve sealing property, simple in construction, ceramic ring is conducive to sealant layer cure shrinkage, improves fluid sealant
The adhesive property of layer, the vertical axis of sealant layer 51 overlaps with the vertical axis of ceramic ring 52, can guarantee that
The stability of sealant layer, improves sealing effectiveness.
During installation, inner wire 1 is loaded in the first insulator 3, then in overall loading outer conductor 1, so
After on the end face tank of the first insulator 3 sealant layer 51, then press people's ceramic ring 52, improve sealant layer 51
Adhesive property, then cover the second insulator 4, after sealant layer 51 solidification, sealing property can be realized,
According to different transmission performances, the thickness of sealant layer 51 and the thickness of ceramic ring 52 can be adjusted.
In addition to above preferred embodiment, the present invention also has other embodiment, and those skilled in the art are permissible
It is variously modified according to the present invention and deforms, without departing from spirit of the present utility model, all should be belonged to this
Scope defined in utility model claims.
