Description
Technical field
The present invention relates to the type millimeter-wave coaxial connectors and its insulation support body in millimeter-wave signal transmission field.
Background technique
Existing type millimeter-wave coaxial connector includes inner conductor, outer conductor and the insulation branch being set between inner and outer conductor
Support body.Wherein the specific structure of insulation support body is as shown in Figure 1 and 2: including ontology 2 made of insulating materials, body central position
Place is provided with the inner conductor mounting hole 4 for installing for corresponding inner conductor, in order to reduce the dielectric constant between inner and outer conductor,
Be provided on the body it is multiple positioned at inner conductor mounting hole periphery along the circumferentially spaced periphery holes 3 of ontology.Simultaneously at this
The end of body is additionally provided with the impedance-compensated slot 1 for impedance matching compensation, and impedance-compensated slot 1 is that one isometrical and bottom is flat
The structure in face.Existing this insulation support body structure has problems in that: as the millimeter-wave signal of Technology for Modern Equipment uses
Frequency is higher and higher, and type millimeter-wave coaxial connector unavoidably increasingly tends to miniaturization, millimeter international at present
Wave coaxial connector, highest frequency of use is 1.0 type connectors, and frequency of use is up to 110GHz, but structure is very small,
Its outer conductor internal diameter only has 1.0mm, so small size, will bring very big be stranded for designing and manufacturing for its insulation support body
It is difficult.
For existing this insulation support body when in face of so small size, the promotion of difficulty of processing at double is existing first
The peripheral pore structure for reducing dielectric constant is too small, it is difficult to process, even if inadequate machine-shaping will also result in, hole wall is excessively thin, and part becomes
Shape.Secondly because periphery holes are too small, it is seldom generally to remove material for part, can not be effectively reduced between internal and external conductor
The dielectric constant of insulating supporting.Again, the collocation structure of this blocked impedance of flat annular groove is only capable of providing fixed offset,
Type millimeter-wave coaxial connector frequency of use is increasingly difficult to bring better compensation effect when higher and higher, to influence millimeter wave
The whole radio-frequency performance of coaxial connector.
Summary of the invention
The purpose of the present invention is to provide a kind of insulation support body that can be improved more preferable compensation effect, the purpose of the present invention
It also resides in and a kind of type millimeter-wave coaxial connector using the insulation support body is provided.
To solve the above-mentioned problems, the present invention in insulation support body technical solution are as follows:

The sectional dimension of slot is gradually become smaller by notch to slot bottom.
The cross sectional shape of the impedance-compensated slot is V-arrangement.
Impedance-compensated slot by joint match therewith V-arrangement lathe tool blade car at.
Be provided on the outer peripheral surface of ontology multiple circumferentially spaced arrangements, along the longitudinal direction run through the ontology periphery
Slot, the cross sectional shape of peripheral groove be it is arc-shaped, peripheral groove by joint match therewith milling cutter milling at.
The technical solution of type millimeter-wave coaxial connector in the present invention are as follows:
Type millimeter-wave coaxial connector, including inner and outer conductor and the insulation support body being set between inner and outer conductor, insulation
Supporter includes the ontology that axis extends along the longitudinal direction, and the mounting hole installed for the inner conductor is provided in the middle part of ontology,
In the impedance-compensated slot that has been peripherally installed with of the mounting hole at least one end end face of ontology, the sectional dimension of impedance-compensated slot by
Notch gradually becomes smaller to slot bottom.
The cross sectional shape of the impedance-compensated slot is V-arrangement.
Impedance-compensated slot by joint match therewith V-arrangement lathe tool blade car at.
Be provided on the outer peripheral surface of ontology multiple circumferentially spaced arrangements, along the longitudinal direction run through the ontology periphery
Slot, the cross sectional shape of peripheral groove be it is arc-shaped, peripheral groove by joint match therewith milling cutter milling at.
The type millimeter-wave coaxial connector is plug or socket.
Before setting is known as there are two the insulation support body, the forward insulation support body in position between inner and outer conductor absolutely
Edge supporter, the insulation support body of position rearward be known as after insulation support body, inner conductor include be sequentially arranged from front to back insert
It connects conductor, switching conductor and rear conductor, the rear end of grafting conductor to pass through in the mounting hole by preceding insulation support body, conductor of transferring
Rear end passes through in the mounting hole by rear insulation support body, after the front end for conductor of transferring is provided with the rear end inserting for grafting conductor
The switching conductor jack of welding, the front end of rear conductor are provided with the rear conductor welded after the rear end inserting for conductor of transferring and insert
Hole.
The invention has the benefit that in the present invention, sectional dimension, that is, slot diameter of impedance-compensated slot by notch to slot bottom by
Gradual change is small, to provide a kind of smooth transition type collocation structure that impedance gradually changes from large to small, can get better impedance
Compensation effect.
Further, for insulation support body lesser for diameter, in the difficult processing for being injection moulded impedance-compensated slot
Degree is very high, and the cross sectional shape of impedance-compensated slot is V-arrangement, can use lathe tool vehicle in this way and goes out impedance-compensated slot, convenient
The processing and fabricating of impedance-compensated slot.
It is by another effect that impedance-compensated tank car goes out using lathe tool, since the wall thickness of insulation support body is smaller, phase
Answer the milling cutter of size very expensive, if processed using milling cutter, processing cost and requirement on machining accuracy are all very high, and are easy
Make insulation support body machining deformation, and use matching V-arrangement lane sword that can go out impedance-compensated slot with a knife vehicle, processing is got up
It is comparable simple and convenient.
