Further, the leading inside wall of described first outer conductor is provided with the first limited step, and described first insulating supporting is provided with the second fixing limited step that to cooperatively interact with described first limited step;
The lateral wall of described first inner wire is provided with the 3rd limited step, and the left end face of described 3rd limited step and the portion rear end face of described first insulating supporting cooperatively interact fixing; Its right end face of described 3rd limited step and the part front end face of described second insulating supporting cooperatively interact fixing;
The rear inside wall of described first outer conductor is provided with the 4th limited step, and the front end face of described 4th limited step and described second outer conductor cooperatively interacts fixing;

Acting as of described cavity: the 3rd limited step on described first inner wire is for fixing the position of the first inner wire, prevent the first inner wire axial endplay, according to difficulty of processing and impedance operator requirement, select air material with the dielectric corresponding to the 3rd limited step.
Be specially, due to designed connector demand fulfillment 50 ohm impedance characteristic, 50 ohm impedance characteristic formula are:
Wherein ε
rfor the relative dielectric constant of dielectric, D is the internal diameter of outer conductor, and d is the external diameter of inner wire;
Dielectric corresponding to cavity selects air material, is due to constant at outer conductor internal diameter, and when inner conductor outer diameter increases, namely in formula, D is constant, and d increases, so only have reduction ε
r, namely reduce the relative dielectric constant of dielectric, the requirement of connector 50 ohm impedance characteristic could be met.The relative dielectric constant ε of polytetrafluoroethylene
r≈ 2.02, the relative dielectric constant ε of air
r≈ 1.So select the air material that relative dielectric constant is lower, again reduce difficulty of processing simultaneously.
Compensate acting as of step: at the 3rd limited step place, due to the mutation disrupts impedance continuity of connector of the first inner wire diameter, coplanar compensation (i.e. where is it sudden change, just compensates at the same plane of sudden change) is carried out in the discontinuous impedance must introduced suddenling change due to the first inner wire diameter; Compensating the effect of step is exactly suddenly change the discontinuous impedance introduced to the impact of connector performance in order to reduce or compensate counteracting by the first inner wire diameter.
Further, the part front end face of described 4th limited step and described second outer conductor cooperatively interacts fixing;
The madial wall of the first outer conductor is provided with the 7th limited step, and the lateral wall of described second insulating supporting is provided with the 8th fixing limited step that to match with described 7th limited step;

Arranging the 7th limited step and the 8th limited step is to better ensure the first outer conductor, firm performance between the second insulating supporting and the second outer conductor after Automatic manual transmission, better ensure that the reliability of designed connector.
Further, the madial wall of described second insulating supporting is provided with the 9th limited step, and the lateral wall of described first inner wire is provided with the tenth fixing limited step that to match with described 9th limited step.
Arranging the 9th limited step with the object of the tenth limited step is: due to the first inner wire sometimes than the microstrip line that will be connected width also wide (coaxial microband connector is used to the interface unit connecting coaxial line and microstrip line), so in order to make the designed coaxial microband connector scope of application wider, so the width of inner wire is attenuated; When the first inner wire herein from the coarse to fine time, must carry out coplanar compensation to the discontinuous impedance introduced that suddenlys change due to the first inner wire diameter, the discontinuous impedance that present design adopts the 9th limited step and the tenth limited step to reduce or compensation counteracting inner wire diameter suddenlys change to be introduced is on the impact of connector performance.
Further, described jockey also comprises a tester, and described tester comprises the 3rd outer conductor, the 3rd insulating supporting, the second inner wire and two insulation spacers;
The two ends place of described 3rd outer conductor offers hole slot respectively along the axial direction of the 3rd outer conductor, is provided with vestibule between two hole slots along the axial direction of the 3rd outer conductor, this vestibule respectively with two through settings of hole slot; 3rd insulating supporting, the second inner wire and two insulation spacers are all arranged in described vestibule;
Described 3rd insulating supporting is set on the lateral wall of the second inner wire, and two insulation spacers are separately positioned on the left and right end face of the 3rd insulating supporting;
Axial direction at the two ends place of described second inner wire along the second inner wire offers connecting hole respectively, and two insulation spacers are equipped with the corresponding through hole that to match with described connecting hole, the aperture of this through hole is equal with the aperture of connecting hole.
Insulation spacer in tester to be used in compensating coaxial microband connector in the first inner wire and tester between the second inner wire because inner wire diameter is suddenly by carefully thicker introduced discontinuous impedance.
The effect of part of detecting and benefit: because designed coaxial microband connector is one port devices, in order to better know the quality of designed processing connector performance, just must test it, the discontinuous impedance introduced when tester effective compensation provided by the present invention coaxial microband connector is connected with tester, science is accurate more to make institute's test result.
Further, the internal diameter of described hole slot is greater than the internal diameter of described vestibule.
The internal diameter of hole slot is greater than the internal diameter of described vestibule, due to impedance operator requirement, when same dielectric medium, the internal diameter of the larger corresponding outer conductor of external diameter of inner wire is larger, if their diameter is equally large, so the thickness of the second outer conductor and the first outer conductor contact portion will be very thin, can not meet reliability requirement.
Further, the lateral surface of two insulation spacers is in same plane with the bottom surface of corresponding hole slot respectively.
The bottom surface of insulation spacer and hole slot is in same plane, is because the requirement of As soon as possible Promising Policy 50 ohm impedance characteristic is wanted in each cross section of coaxial microband connector, if outstanding or recessed, all can cause new resistance matching problem, and add design difficulty; In other words, concordantly can compensate the discontinuous impedance introduced when the first inner wire inserts the second inner wire well, there is structure simple, the advantage such as easy to process.
Further, connecting hole and vestibule are coaxial setting; The axial length of described 3rd insulating supporting is equal with the axial length of described second inner wire.
Connecting hole and vestibule are coaxial setting, and the 3rd insulating supporting has identical length with the second inner wire, are due to the 3rd insulating supporting, the 50 ohm impedance characteristic requirements meeting connector between the second inner wire and the 3rd outer conductor.It is to coaxial microband connector and tester be carried out being connected measuring that first inner wire inserts the second inner wire, and because inner wire diameter is by carefully thicker, carries out impedance-compensated so devise insulation spacer.
