Be equipped with identical via-hole array on described test plane and the boss, described via-hole array is corresponding one by one with the slurry through hole of battery sheet; The quantity of described through hole with distribute all with to carry on the back the slurry through hole that contacts the battery sheet corresponding, promptly determine by the structural design of the front and back of battery sheet; Generally speaking, the quantity of through hole is 16 ~ 80, and the size of through hole is about 1 ~ 1.5 cm.Thereby the hole resistance that the probe that utilizes testing tool comes the testing size through hole by the front electrode and the backplate both sides of each through hole contact battery sheet.
In the technique scheme, described test plane is as the criterion square, and the bottom on test plane is provided with at least 1 register pin; The boss bottom of described portable plate is provided with the groove that cooperates with described register pin.Described register pin can be cylindrical, and groove can be semicircle.Notch is formed on the bottom that acts on the test plane of register pin, to make things convenient for the fetching battery sheet.
In the technique scheme, described buffering elastic component is a spring, circumferentially be distributed in fixed head around.
In the technique scheme, described base, fixed head and portable plate are insulating part.As adopting conventional insulating material such as quartz or teflon.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model design has obtained a kind of test fixture that detects the battery sheet resistance that is exclusively used in, and can improve the efficient of test greatly, and prevent the error of manual operation greatly, has increased reliability of testing result.
2, of the present utility model rational in infrastructure, be easy to realize that cost is lower, and has good operability, practicality, is suitable for applying.
3, the utility model is provided with the guidepost and the pilot hole of magnetic, and the buffering elastic component is set between fixed head and portable plate simultaneously, thereby in locking back of the body contact battery sheet, has reduced the shortcoming of standard machinery clamp device, has reduced the fragment rate of battery sheet.
