Description

Probe for battery test and its probe module {PROBE FOR BATTERY TEST AND THE PROBING MODULE}

The present invention relates to a battery test probe and a probe module thereof.

Current and voltage are applied to the active charging/discharging environment of the secondary battery. Specifically, current and voltage are applied by a battery test probe, also called a battery pin. Therefore, in the test process after production of a secondary battery, that is, a battery, this battery pin plays an important role.

Specifically, when current and voltage are applied, the battery pins contact the secondary battery, and accordingly, durability and reliability of the battery pins become very important factors.

In general, battery makers' replacement cycle of battery pins is at least one year, and depending on the number of uses, the contact surface of the battery that is in contact with the battery's electrodes (positive and negative electrodes) cannot always be in good condition. Accordingly, when the contact surface of the battery pin becomes dull and gas and arc discharge due to foreign substances are not conspicuously generated, the yield of the battery to be tested is lowered and defects increase in the charging/discharging process.

In addition, when the battery pin is replaced with a cylindrical body, a high cost is incurred.
