Probe for testing secondary battery

The present invention relates to in recessed portion can improve the charge and discharge efficiency to ensure sufficient contact between the charge and discharge probe secondary battery testing of the terminal, is in contact with the electrode of the battery charge-discharge operation when the battery in the charging and discharging probe for applying an electric current in, the interior of the through-tube to the vertical; And possibly through the lifting insert to the tube, and inside the through up and down, the first chungbang all in contact with the electrode at the bottom of the cell; The tubular body and is arranged between the first elastic member 1 chungbang all push downward the first charge-discharge portion; The first enable saptal fitted inside the lower end of chungbang all, protrudes downward and contacts the lower end of the battery electrode, the interior of all the second chungbang the through up and down; It said first, second, and non-contact each other to enable the lifting insert doedoe the chungbang all through, the voltage measurement unit in contact with the electrode at the bottom of the cell; The first is the one naeseol chungbang all of the second elastic member to push downward the voltage measurement portion; characterized in that it comprises a. According to this embodiment, such an advantage can be more stably proceed with the charge-discharge operation, since the contact is made over the terminal across all including the cup area of ​​the terminal.
