The both ends of frock insulation shell 1 are tightly connected；The bottom of frock contact point 2 is provided with hole slot；The described both ends of copper-manganese sampling resistor 3 point
It is not plugged in the hole slot of two frock contact points；Above-mentioned two frock contact point 2 is both positive and negative polarity contact point.
Further, the bottom hole slot inner surface of described frock contact point 2 is provided with nickel coating.
The operation principle of present embodiment：When in use, frock contact point 2 crimps calibration tool with probe groups, manganese
Copper sampling resistor 3 turns on, the resistance and the calibration of copper-manganese sampling resistor 3 that now can detect probe side give offset；Then will
Calibration tool is crimped with lithium ion battery, and the open-circuit voltage of lithium ion battery has been calibrated with offset.
Embodiment：
Referring to Fig. 3, circular lithium-ion batteries open-circuit voltage calibration tool and practical lithium-ion are in the same size, directly will
Calibration tool batch is put into lithium ion battery pallet to be crimped with probe groups, it is possible to implements test function.
After said structure, present embodiment has the beneficial effect that：Circular lithium described in present embodiment from
Sub- battery open circuit voltage calibration tool, it is possible to increase trim efficiency, avoid the situation for occurring loose contact and fracture during crimping, dress
Easy replacing is put, it is easy to operate, influence of other media to measurement accuracy in air is reduced, ensure that the precision of equipment, and production
The security of product, the utility model have simple in construction, and it is reasonable to set, the advantages that low manufacture cost.
It is described above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
