Specific embodiment
With reference to the accompanying drawings and examples, the present invention will be described in detail.
Embodiment, a kind of test device of rf probe, as shown in Figure 1, the perforative RF coaxial shell 1 in both ends, grafting
It is being installed on the test adaptor device 2 of 1 axial end portion of RF coaxial shell and is being electrically connected to the host control terminal of test adaptor device 2
3.When detecting rf probe, rf probe is inserted into RF coaxial shell 1 and test adaptor device 2 is electrically connected, so that rf probe
Output radiofrequency signal test adaptor device 2 conversion after be transported to host control terminal 3.
As shown in Figure 1, 2, specifically, RF coaxial shell 1 includes offering mounting hole for the inner shaft of rf probe grafting
Cylinder 11, be arranged the outer bottom cylinder 12 being fixed on interior beam barrel 11 towards 2 side of test adaptor device, sliding is sheathed on interior beam barrel 11 far from surveying
It tries the outer top cylinder 13 of 2 side of adapter and is set between outer bottom cylinder 12 and outer top cylinder 13 to have to drive outer top cylinder 13 far from outer
The elastic component 14 of 12 elasticity of bottom cylinder.The structure of mounting hole corresponds to rf probe and is set as the small stepped hole 15 of outer imperial palace, mounting hole
Internal diameter be slightly larger than the outer diameter of corresponding rf probe, enable rf probe that beat occurs in mounting hole.
As shown in Figure 1, 2, the limit that restricted outer top cylinder 13 skids off interior beam barrel 11 is set between outer top cylinder 13 and interior beam barrel 11
Position is secondary；When the limit secondary by limit of outer top cylinder 13, outer top axial end face of the cylinder 13 far from rf adapter is from interior beam barrel 11 from penetrating
It is protruded at the axial end face of frequency adapter.Therefore under the action of elastic component 14, when non-stress, outer top cylinder 13 is to separate outer bottom cylinder
12 direction sliding is remain the state that outer top 13 axial end face of cylinder is protruded from interior 11 end face of beam barrel by the secondary limit of limit.
As shown in Figure 1, 2, the axial length of outer bottom cylinder 12 is about the 2/3 of interior beam barrel 11, and the axial length of outer top cylinder 13 is big
About the 1/5 of axial length, elastic component 14 are the pressure spring being sheathed on interior beam barrel 11, and the both ends of pressure spring are connected to outer top cylinder respectively
13 and outer bottom cylinder 12.
As shown in Figure 1, 2, it is arranged between the outer circle of beam barrel 11 and the inner circle of outer top cylinder 13 in outer top cylinder 13 and interior beam barrel 11
There is beat interval.So that the different circumferential positions of the outer top cylinder 13 of disalignment pressing, outer top cylinder 13 can drive rf probe to send out
Raw axial beat.Specifically, top axial end face of the cylinder 13 far from rf adapter is from interior beam barrel 11 from rf adapter outside
The distance protruded at axial end face is 1.0 to 1.6mm, so that radio-frequency probe has the surplus axially slid in mounting hole, and
Guaranteeing the connection between test adaptor device 2 and radio-frequency probe in slipping.The outer circle of beam barrel and it is outer top cylinder 13 inner circle it
Between beat be set to 0.1 to 0.16mm.
Further, as shown in Figure 1, 2, it includes being integrally connected to interior 11 outer circle of beam barrel far from 12 side of outer bottom cylinder that limit is secondary
Outer ring flange 16 and be integrally connected to it is outer top 13 inner circle of cylinder face out bottom cylinder 12 sides interior ring flange 17.Outer ring flange 16
Interval between outer top 13 inner circle of cylinder is greater than the interval between interior 11 outer circle of beam barrel and interior ring flange 17.Specifically, outer ring convex
0.16mm is divided between edge 16 and outer 13 inner circle of top cylinder, between interior 11 outer circle of beam barrel and interior ring flange 17 between be divided into
0.1mm.By the spacing of beam barrel 11 outer circle and interior ring flange 17 in reducing, cylinder 13 and interior beam barrel 11 are pushed up outside when being able to ascend beat
Between the stability that connects.
As shown in Figure 1, 2, host control terminal 3 receives the standing wave signal transmitted from test adaptor head, calculates and obtains standing wave letter
Number test standing-wave ratio, based on compare test standing-wave ratio and default standing-wave ratio threshold value output judge signal.Testing standing-wave ratio can
React the comparison of the information of the output of rf probe and reference information in each period, in a short time can be multiple to radio frequency
The sending detection information of probe realizes the accurate detection to rf probe.
In general standing-wave ratio SWR=R/r, wherein R and r is output impedance and input impedance respectively.Therefore by obtaining one
As the output impedance R of the rf probe and input impedance r of test adaptor head, the standing-wave ratio threshold value SWR of standard can be got.
And when testing the detection standing-wave ratio of radio-frequency probe, by obtaining the standing wave power of forward and reverse, wherein positive
Standing wave power is that P is just anti-with reversed standing wave power P, and to calculate standing-wave ratio, calculation formula is as follows:
Therefore host control terminal 3 is stayed by the detection that preset standard standing wave threshold value SWR and calculating are obtained test radio-frequency probe
Bobbi SWR is compared, and be will test and is obtained the be above standard radio-frequency probe of standing-wave ratio threshold value SWR of detection standing-wave ratio SWR and be labeled as
It is unqualified.Wherein positive standing wave power be the P just anti-sampling period with reversed standing wave power P can be standing wave half period or
Person's a cycle.
The test method of test device rf probe, comprising:
Step 1, rf probe is inserted into the mounting hole of RF coaxial shell 1, so that the acquisition rf probe of test adaptor device 2 is defeated
Radiofrequency signal out；
Step 2, along the circumferential pressing rf probe of rf probe, so that rf probe generates axial sliding in mounting hole, and
Occurs the beat of all angles in mounting hole；
It preferably, include along 0 °, 90 °, 180 ° and 270 ° of position of frequency probe along the circumferential pressing rf probe of rf probe
It presses rf probe 5 times respectively.It is about 5 times/2 seconds that the frequency for pressing rf probe, which is frequency,.To penetrate in pressing rf probe
While frequency probe slides in mounting hole, it may occur that beat；It realizes quickly and comprehensively to the signal detection of rf probe.
Step 3, host control terminal 3 receives the standing wave signal that transmit from test adaptor head, based on compare test standing-wave ratio with
Default standing-wave ratio threshold value output judges signal.
As long as test standing-wave ratio occur in period exceeds default standing-wave ratio threshold value, host control terminal 3 will occur unqualified
Judgement signal.
The present invention has the beneficial effect that:
Since outer top cylinder 13 is protruded above from interior beam barrel 11, and can slide on interior 11 outer wall of beam barrel, therefore operator can
By pressing rf probe, so that rf probe generates axial sliding while testing, beat occurs on one side.And every time
It can all automatically reset under the action of elastic component 14 after axial sliding, then be slid next time；To in test rf probe
When, rf probe is not the characteristic for testing rf probe in the stationary case, to obtain under more type multiple-situation, is more surveyed comprehensively
Measure rf probe performance.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
