In coaxial configuration design, the coaxial configuration of mainly internal and external conductor designs, in order that RF coaxial pole assembly 14
Regard as on the whole as approximate a bit of hard coaxial line with radio-frequency (RF) coaxial plugging hole component 24, reduce structure as far as possible in design
Part.In order to make it have good interface fit, during structure design, axial interface size substantially conforms to standard；Radial direction interface dimensions
The inserting diameter conformance with standard of only inner wire requires, and diameter is taken as 1mm.According to the theory of coaxial transmission line, for propagation TEM
The coaxial line of ripple；
The characteristic impedance of its cross section is calculated as follows：
In formula：Z0 characteristic impedance (Ω)；
D outer conductor internal diameter (m)；
D inner conductor outer diameter (m)；
The relative dielectric constant of dielectric material between ε i internal and external conductor.

GB9020—88《Video coaxial connector generic specification》Design, produce and using video coaxial connector according to
According to, but this standard specify only technical requirements and the method for inspection of video coaxial connector, specific structure is not done and specifies.
GB9020 defines the structure of the video coaxial connector of several models, but inner wire diameter is bigger than normal, so video axial contact
Assembly requires designed, designed according to the specifically used of whole machine.
The structure design principle of power pin assembly 13 and supply hub assembly 23 is as follows：
The core number of power pin assembly 13 and supply hub assembly 23 inner wire is 3, and wherein G foot is earthing pole, in it
Conductor diameter is 1.57mm, and rated current is 10A, is equivalent to No. 16 contact pins specified in GJB598A, requires 16 in GJB598A
Minimum spacing between number contact is 0.9mm, be according to this according to design insulated mounting plate hole position arrangement as Fig. 7 it is ensured that each
Between individual contact, the distance between contact and shell be all higher than or be equal to 0.9mm.Shell and the installing plate of power connector

Docking cooperation well.
The low frequency configuration design principle of filtering contact pin component 16 and filtering plugging hole component is as follows：
Low frequency contact is formed with filtering plugging hole component by filtering contact pin component 16, has 30 low frequency contacts.Elasticity is inserted
The cylinder that the structure design of hole contact is common opens the fan-shaped reed structure of two grooves.Filtering contact pin uses π type low pass filtered
Ripple device, filter element adopts tubular structure.The filter element of tubular capacitor and tubulose magnetic core composition is loaded contact pin and terminals
Low frequency filtering contact pin component is formed between son.
The structure design design principle of grounding reed 17 is as follows：
Take shielding measure and filter circuit to combine be the method for modal suppression interference, therefore often filter circuit
Also serve as a kind of shielding measure.From the point of view of anti-interference, in addition to shielding measure, also there is a grounded circuit problem, if
Screen imperfect earth can affect shield effectiveness, so the design of earthed system is equally the subject matter of disturbance-proof design, in knot
It is necessary to give enough attention during structure design.Filtering contact pin earth-return circuit in the design is by grounding reed 17 and filter
The tubular condenser of ripple contact pin and electric connector housing coordinate, and then electric connector housing is fixed on to be formed with frame in frame and connects
Ground network, in addition, for the methods of parasitic feedback suppressing earth-current to produce through base, using one point earth, will radio frequency, video and
Form cooperation between the outer conductor of electrical power contacts assembly and grounding reed 17.So the design of grounding reed 17 is to ensure that ground connection can
