Embodiment
Currently preferred embodiment of the invention is reference will now be made in detail to now, its example is shown in the drawings.In whole accompanying drawings
Identical is represented using identical accompanying drawing or similar part as much as possible.
Accompanying drawing 1 is compareed, a kind of impedance adjustable section millimeter wave bent type radio frequency coaxial connector performs assembling in the following order：
Inner wire 1 is loaded into the 3rd shell 7, the second bushing 4 is loaded into the first shell 5, insulator 2 is used into cut, is reloaded into interior
On conductor 1, the first bushing 3 is pressed into, second housing 6 is screwed on；Second bushing 4 is loaded into the first shell 5, insulator 2 is used into blade
Cut, be reloaded on inner wire 1, press upper first bushing 3, screw on the 3rd shell 7.Snap ring 8 is loaded into second housing 6, then by spiral shell
Set 9 is pressed on snap ring 8.Product is connected on progress electrical property debugging on Network Analyzer.Apply and lead in right amount on the screw thread of adjusting screw 10
Electric glue, is screwed into the first shell 5, by the position adjustment product standing wave of adjusting screw 10, meets and is placed after requiring, treats that conducting resinl is consolidated
After change, repetition measurement index is qualified to apply appropriate epoxy resin encapsulated to the afterbody of adjusting screw 10 afterwards.
Accompanying drawing 2 and accompanying drawing 2-1 are compareed, the first shell 5 has adjusting screw hole, product impedance is realized by adjusting screw
Regulation.Millimeter wave product precision prescribed when designing production is very high, the slightly overproof electrical property reduction that may may result in product,
This proposes a great problem to processing.Domestic existing level of processing is difficult to meet so high required precision, and part is not
Qualification rate is very high.In order to solve this problem, it is proposed that the impedance time domain for adjusting product by adjusting screw in corner is special
Property, the error in Product processing manufacturing process is offset, the voltage standing wave ratio and qualification rate of product is lifted.
Accompanying drawing 3 is compareed, product is used the first shell 5, second housing 6, the Split type structure of the 3rd shell 7, connected using screw thread
Binding structure.In order to improve the electrical performance indexes of product, integral inner wire bending structure is employed.Integral inner wire can not be by such as
The endoporus of this length loads product, therefore employs split shell mechanism.And the first shell 5 is general part in split shell,
Second housing 6, the 3rd shell 7 are apolegamy part, and two second housings 6, which are coupled, in the first shell 5 can realize the double sun connections of curved formula
Device, two the 3rd shells 7, which are coupled, in the first shell 5 can realize curved formula jack to jack adapter connector.By curved formula structure is than straight structure institute
The strength and moment of torsion to be born is bigger, and in order to avoid obscission occurs in curved formula shell, product employs screw connection structure.
Accompanying drawing 3-1 is compareed, product uses the first shell 5, second housing 6, the Split type structure of the 3rd shell 7, using welding
Fixed structure.
Accompanying drawing 3-2 is compareed, product uses the first shell 5, second housing 6, the Split type structure of the 3rd shell 7, using riveting
Fixed structure.
Accompanying drawing 4, such as accompanying drawing 4-1, Fig. 4-2 and accompanying drawing 4-3,5 milling of the first shell, two breach and an oblique angle are compareed, with reality
The normal loading of existing integrative-structure inner wire 1.Product is loading the first shell 5 using integral bending inner conductor structure, inner wire 1
When due to aperture it is smaller, and inner wire 1 is longer, so the situation of interference occurs.In order that inner wire 1 can load production
Product, two breach of milling on the first shell 5, while add an oblique angle structure in corner.
Accompanying drawing 5, such as accompanying drawing 5-1, Fig. 5-2 and accompanying drawing 5-3,5 milling of the first shell, one breach and an oblique angle are compareed, with reality
The normal loading of existing integrative-structure inner wire 1.Product is loading the first shell 5 using integral bending inner conductor structure, inner wire 1
When due to aperture it is smaller, and the contact pin end longer dimension of inner wire 1, so the situation of interference occurs.Because inner wire is inserted
Nose end size is shorter, can also realize that inner wire 1 loads product by milling one breach, and milling one lacks on the first shell 5
Mouthful, while adding an oblique angle structure in corner.
Accompanying drawing 6 and accompanying drawing 6-1 are compareed, inner wire 1 is using integral milling oblique angle structure.Adjusting screw 10 stretches into the first shell 5
The depth of cavity is deeper, and characteristic impedance herein can be lower.In order that characteristic impedance reaches 50 Ω requirement, first it can be led interior
The milling oblique angle of body 1 so that the impedance of the empty cavity position of the first shell 5 is slightly above 50 Ω, adjusts production by adjusting screw 10 again afterwards
Product impedance is allowed to be finally reached 50 Ω matchings, improves product radio frequency transmission performance.
It will be apparent for a person skilled in the art that various modifications and variations can be made to the present invention without departing from this hair
Bright spirit and scope.Therefore it is contemplated that the modification and variation of the present invention are covered, as long as these modification and variation are appended
