Plug-in high precision electrical parameters detection anchor clamps
Technical field
The utility model relates to a kind of anchor clamps of clamping workpiece for measurement, especially relates to a kind of structural improvement that cooperates the anchor clamps of the magnetic test coil inductance that high precision electrical parameters detection device uses.
Background technology
Some industry requires to have reached microhenry even nanohenry level to the accuracy of detection of the inductance value of coil.For this reason, people have carried out various explorations, have developed the instrument of the electrical quantity such as inductance, electric capacity, resistance of multiple high Precision Detection element.The measuring accuracy of these instruments self has reached quite high level, and reacting phase can satisfy Testing requirement fully when sensitive; But problem of ubiquity---lack the anchor clamps that are used for the clamping element under test.Therefore, in measuring process, need to make the detection line of instrument contact with element under test by manual.Because operating personnel are stable inadequately to the element under test applied pressure when detecting, so the error of its measurement is bigger.Become the bottleneck that improves accuracy of detection just because of the anchor clamps this point that lacks the clamping element under test.In the measuring instrument of other industry, the invention that detects anchor clamps is also reported to some extent, for example Chinese patent literature has been announced a kind of detection anchor clamps (application number: 01257698.0) that is applicable to semiconductor laser, side at the carriage of placing laser instrument to be checked is provided with 5 to 30 square grooves, the outer of this square groove bottom and both sides is provided with hard contact, anchor clamps comprise that also one has the clamping part of the protuberance that matches with square groove simultaneously, and the forcing screw by alternate band spring between carriage and the clamping part accurately reaches fixing in the location.This detection anchor clamps, simple to operate, the way of contact of its squash type can reduce in the testing process the damage of pipe, can be suitable for using in the industrialized large-scale production.But this anchor clamps can only be suitable for and this kind equipment, and its versatility is relatively poor, can't use with other coordinative composition of equipments, thereby use cost are higher.And, can also not report to some extent so far with the anchor clamps that high Precision Detection electrical quantity instrument matches.In addition, because the precision of measuring is higher, treat that the pin of test coil also can cause significant impact to measurement result in measuring process.The error recovery procedure of existing detecting instrument is comparatively complicated, and calibration result is also not satisfactory.And in testing process, superimposed current is bigger, the precision that influence detects.
Summary of the invention
The utility model mainly is to solve the existing in prior technology element under test to be difficult for the location, detects between contact and element under test not balance very of pressure, and the disturbing factor of manual inspection is too much, and accuracy of detection is not high enough, the technical matters of the excessive grade of the superimposed current during detection.
The utility model has solved the trimming process complexity of existing in prior technology anchor clamps simultaneously again, and calibration result is not satisfactory, and versatility is bad, the technical matters that use cost is more high.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: plug-in high precision electrical parameters detection anchor clamps, comprise the chuck supporting plate, on the chuck supporting plate, be provided with the workpiece locating piece, it is characterized in that on described chuck supporting plate, being provided with gathering sill, be provided with the jack that links to each other with terminal block in the described gathering sill, described jack is provided with plug type sheet inductance; Both sides at described terminal block are respectively equipped with grip block, and the end of described grip block matches with elastic body.The utility model positions magnetic core by two grip blocks being located in the gathering sill, and the sheet inductance links to each other with terminal block by unique plug-in structure.Be convenient to the adjustment of sheet inductance like this, change; Make that simultaneously contact is more tight, measuring error significantly reduces.
For the accuracy that guarantees to measure, as preferably, the utility model also is provided with correcting member, and described correcting member system is by insulation handle and provided thereon forming with the corresponding some contact pins of jack.Because what the utility model adopted is the plug-in contact, thereby the replacing between sheet inductance and the correcting member is very convenient.Can earlier correcting member be inserted in before using with jack that terminal block links to each other in carry out the short circuit correction.After correction is finished, correcting member is extracted, plugged the sheet inductance and can measure, its error recovery procedure is very convenient.
As preferably, described plug type sheet inductance comprise telefault and with the corresponding some pins of jack.So both helped telefault and be connected, helped the carrying out of error correction again with the tight of checkout equipment.
In order to guarantee the effect of error correction, as preferably, the equal in length of the pin length of described plug type sheet inductance and the contact pin of correcting member.The error that pin brought and all the other errors of plug type sheet inductance can be corrected effectively like this.
As preferably, a described grip block matches with two groups of elastic bodys at least, is provided with plectrum on described grip block.Two groups of elastic bodys are set have further improved grip block traveling comfort in gathering sill, plectrum is set on grip block simultaneously is convenient to operation grip block.
In order to improve grip block traveling comfort in gathering sill, as preferably, be provided with the guiding push rod between described grip block and elastic body, described elastic body is located in the pilot hole of gathering sill.Make it stressed steadily like this, unlikely generation grip block stuck phenomenon.
In order further to improve the guide effect to grip block, as preferably, described grip block is made as one with the guiding push rod.
As preferably, the outer rim of described grip block matches with the inner edge of gathering sill, is provided with the guide and limit bar on described gathering sill.
As preferably, described plug type sheet inductance is made by 1~3 sheet metal, and its inductance size is 0.010000 microhenry~0.080000 microhenry.
Therefore, the utlity model has following advantage: 1, realized the clamping of element under test effectively, avoided hand to pinch the drawback of detection; 2, pick-up unit and element under test contact closely, the pressure during detection is even; 3, error correction is convenient, and calibration result is obvious; 4, antijamming capability is strong, and line design is reasonable; 5, highly versatile, can with the supporting use of multiple inductance measuring tester; 6, measuring accuracy height, good operating stability, use cost is low.
