The structure of above -mentioned line knot that walks who cut straightly type radio frequency connector constructs pad adopts the gradual change to walk the mode of line, and the line is walked in the gradual change makes the impedance continuously change, but not the sudden change reaches certain impedance compensation. Adopt not unidimensional anti - pad simultaneously, considered the different electromagnetism circumstances in different layers to optimized and walked the impedance characteristic that line knot constructs.
Description
Technical field
This utility model is related to a kind of direct plugging-in radio frequency connector, especially relates to a kind of walking of direct plugging-in radio frequency connector
Line structure.
Background technology
With the development of technology, sharply increasing of electronic functionalities leads to product design towards Highgrade integration, synthesis
The direction changed is developed.But at present in synthesization electronic equipment, due to the high performance requirements to signal transmission, tens megahertzs
Frequency microwave signal to several Gigahertzs still mainly adopts traditional interconnection mode of various radio-frequency cables so that cloth in frame
If radio-frequency cable number get more and more, cause product reliability to reduce, to the miniaturization of product, lighting, highly integrated set
Meter brings great adverse effect.
The frequency range of existing microwave backboard typically in the range of 1ghz～5ghz, for ensure plate on radiofrequency signal property
Can, typically can using radio-frequency maser costly, or even need to customize radio-frequency maser, this undoubtedly increased to our back plate design
Cost and device buying difficulty.At present, the signal pin of the Wiring structure of existing direct plugging-in radio frequency connector is similar to one
Via structure, its impedance is less than 50 Europe, and about generally 30 Europe, therefore this signal pin can bring impedance discontinuity problem.
Utility model content
The purpose of this utility model is to provide a kind of Wiring structure of direct plugging-in radio frequency connector, to solve prior art
The impedance discontinuity problem that middle direct plugging-in radio frequency connector brings because of signal pin.
For reaching this purpose, this utility model employs the following technical solutions:
A kind of Wiring structure of direct plugging-in radio frequency connector, it includes pcb plate, and described pcb plate is provided with for connecting
The pad of radio-frequency maser signal pin and several earth points, wherein, described pad includes rounded portions, and described rounded portions pass through cone
Shape portion is connected with radio-frequency maser signal pin, and one end that described tapered portion connects radio-frequency maser signal pin is less than the other end.
Especially, described pad and each layer of described pcb plate form anti-pad, and the size of each layer anti-pad is different, is located at
The anti-pad size of the bottom is minimum.
Especially, described earth point is set to 4, is square and is distributed in the outside of described pad.
The beneficial effects of the utility model are that compared with prior art the Wiring structure of described direct plugging-in radio frequency connector is deposited
In following advantage:
1) by the way of gradual change cabling, gradual change cabling makes impedance persistently change to the structure of pad, and not mutated, and by
There is anti-pad, therefore just cabling out, without reference to plane, reaches certain impedance from this disk at radio-frequency maser signal pin
Compensating action.
2) adopt various sizes of anti-pad it is contemplated that the different electromagnetism situation of different layers, thus optimizing Wiring structure
Impedance operator.
Brief description
Fig. 1 is that the structure of the Wiring structure of direct plugging-in radio frequency connector that this utility model specific embodiment 1 provides is shown
It is intended to.
Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
Refer to shown in Fig. 1, Fig. 1 is walking of the direct plugging-in radio frequency connector that this utility model specific embodiment 1 provides
The structural representation of line structure.
In the present embodiment, a kind of Wiring structure of direct plugging-in radio frequency connector includes pcb plate 1, and described pcb plate 1 is arranged
There are the pad 3 for connecting radio-frequency maser signal pin 2 and four grounded point 4, described four grounded point 4 is square and is distributed in institute
State the outside of pad 3.Described pad 3 includes rounded portions 30, and described rounded portions 30 pass through tapered portion 31 and radio-frequency maser signal pin 2
Connect, one end that described tapered portion 31 connects radio-frequency maser signal pin 2 is less than the other end, that is, the cabling drawn adopts gradual change cabling
Mode, gradual change cabling makes impedance persistently change, and not mutated, and there is anti-pad by radio frequency connector signal pin,
Therefore from this disk just cabling out without reference to plane, herein the impedance computation mode of cabling different with having with reference to flat backward
The normal cabling in face, therefore also can reach certain impedance-compensated effect using thicker cabling mode.
Described pad 3 forms anti-pad with each layer of described pcb plate 1, and the size of each layer anti-pad is different, positioned at the bottom
Anti-pad size minimum, in figure dotted line represents the different size size of each layer anti-pad.Various sizes of anti-pad can be excellent
Change the impedance operator of signal pin, for the structure of similar signal contact pin or via, increase the resistance that anti-pad can optimize structure
Anti- characteristic, typically all improves structural impedance and is allowed to be closer to 50 Europe of standard, thus reducing impedance discontinuity.Relatively
In the anti-pad of conventional uniform sizes, this programme anti-pad size considers the different electromagnetism situation of different layers.In general,
Solenoid condition for the plane layer near the routing layer having signal to connect and the top layer related to radio frequency connector is normal with other
Rule plane layer difference is larger, and anti-pad size therefore on this two classes plane layer can be with single optimization, and non-usage uniform sizes.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not subject to above-mentioned example
Limit, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and change, these changes
Change and change and both fall within the range of claimed this utility model.This utility model claims scope will by appended right
Ask book and its equivalent thereof.
