The effect of support.
In the present embodiment, the central axes of the slide opening 64 and the central axes of jack 4 are overlapped, and are inserted into capacitor pin smoothly
In inner cavity 12.
In the present embodiment, 74 upper surface of supporting table is equipped with rubber layer, since the top of capacitor pin is in insertion
It is contacted after chamber 12 with supporting table 74, protection is played the role of by top of the rubber layer to capacitor pin.
In the present embodiment, 1 upper surface of pedestal is equipped with graduated scale 9, the graduated scale 9 and 2 opening of regulating tank
Top edge is parallel, is equipped with pointer 10 towards the side of graduated scale 9 on the adjusting block 3 of 2 inner right side of regulating tank, passes through scale
Ruler 9 and pointer 10, which facilitate, adjusts the distance between two adjusting blocks 3, between so that the distance between adjusting block 3 is adapted to capacitor pin
Away from.

Line between the zero graduation line of ruler 9 and 4 center of circle of jack of another 3 upper surface of adjusting block is parallel to the left edge of pedestal 1, uses
Spacing is observed when adjusting the spacing between adjusting block 3 come the personnel of being convenient for measuring.
The course of work and principle: it before measuring capacitor's capacity, is adjusted insert according to the pin spacing of detection sample 14 first
The center in hole 4 is away from the process of adjustment is: rotation adjusting rod 81 manually, and adjusting rod 81 drives 84 turns of driven wheel by driving wheel 83
It is dynamic, and then screw rod 85 is driven to rotate, since screw rod is threadedly coupled with threaded hole 87, and then pass through rectangular slab 86 drive it is corresponding
Adjusting block 3 moves on rectangular channel 88, observes position of the pointer 10 on graduated scale 9 at this time, when the signified graduated scale 9 of pointer 10
On scale with detection the pin spacing of sample 14 it is equal when, stop operating adjusting rod 81.After the completion, to will test sample 14 logical
Jack 4 is crossed to be inserted into inner cavity 12, detect sample 14 pin during insertion, it is possible that following situation: working as detection
When the pin of sample 14 is completely inserted into inner cavity 12, after the pin for detecting sample 14 touches supporting table 74, pass through adjusting
Screw rod 710 drives sliding bar 71 that the elastic force of the 4th spring 74 is overcome to move down in sliding cavity 78, while wing plate 77 is in wing plate
It is moved in slot 79, guarantees that sliding bar 71 not can rotate, during sliding bar 71 moves down, since check lock lever 66 is located at locking
Inside slot 75, therefore, sliding bar 77 drives drive block 61 to overcome the thrust of second spring 63 along side slot 65 to inner cavity 12
Lower part is mobile, and since drive block 61 moves down, traction rope 610 will have the state for tending to be loose, at this moment in tension spring 58
Pulling force effect under, make Rotational Cylindrical 55 upwards along annular guide post 57 rotate, when conductive end 51 start to pin clamp when,
Conductive end 51 can compress the first spring 53, and at this moment the pressure value of pressure sensor 54 can be with the pressure of the first spring 53
It contracts and increases, after pin is completely inserted into inner cavity 12, the pressure value that pressure sensor 54 is experienced remains inconvenient, is measuring
When capacitor, to guarantee that conductive end 51 and pin are in close contact, guarantee the stability being powered, while needing to take into account conductive end 51
Cannot be excessive to the pressure of pin, the excessive damage that will cause pin of pressure, therefore pressure sensor 54 is equipped with a threshold value, when
After detection sample 14 is completely inserted into inner cavity 12, if the threshold value that pressure sensor 54 is experienced is less than pressure threshold, explanation
The pin insufficient pressure of the 51 pairs of detection samples 14 in conductive end, turns adjusting screw rod 710 at this time, it is made to drive sliding bar 71 downward
It is mobile, conductive end at this moment will be driven to apply pressure to the pin of detection sample 14 by linkage mechanism 6, when the pressure applied
When power reaches the threshold value of pressure sensor 54, stop adjusting adjusting screw rod 710, if the threshold value that pressure sensor 54 is experienced is more than
Pressure threshold inverts adjusting screw rod 710, until the pressure that pressure sensor 54 is experienced reaches threshold value；When detection sample 14
Pin when being completely inserted into inner cavity 12, pin still can not touch supporting table 74, at this moment, pass through rotation threaded rod first
72, make threaded rod 72 that supporting table 74 be driven to touch pin, at this moment linkage mechanism 6 still can not move down, to can not make
Clamping device 5 grips effect to pin formation, will test sample 14 at this time and takes out, makes supporting table again by threaded rod 72
Face continues up raising suitable distance, then will test sample 14 again and is inserted into inner cavity 12, makes clamping device 5 to pin shape
At clamping action, the pressure of pressure sensor 54 is at this moment adjusted by adjusting screw rod 710 again.After the completion of adjusting, by electricity to be measured
Container pin is inserted into inner cavity 12 and is measured by jack 4, after measurement, by lower button 14, and at this moment electromagnet 68
Electric generation magnetic force is obtained, suction is generated to check lock lever 66, it is made to overcome the elastic force of third spring 67 to the direction close to electromagnet 68
It is mobile, when check lock lever 66 completely disengages locking slot 75, under the pulling force of second spring 63, it will drive drive block 61 to inner cavity
12 top is mobile, so that conductive end 51 be made to unclamp the pin of capacitor, at this moment takes out after release button 13 and surveys measured electricity
Container, in release button 13,68 power loss of electromagnet, surface of the check lock lever 66 under the thrust of third spring 67 with sliding bar 71
Contact, after taking out capacitor, under the elastic force of the 4th spring 76, sliding bar 71 is moved up, and in moving process, works as locking
When slot 75 and 66 face of check lock lever, check lock lever 66 is moved in locking slot 75 under the action of third spring 67, after the completion,
Measure next capacitor.
Based on above-mentioned, using a kind of pin clamping device of capacitive detection system of the invention, before measuring capacitance,
It first passes through regulating mechanism and adjusts distance of center circle between two jacks, keep distance of center circle equal with the pin spacing of capacitor, then basis is drawn
Foot length suitably adjusts driving mechanism, makes pin when being inserted into jack, can make driving mechanism normal driving linkage mechanism, survey
