Terminal contacting part included in a jig for charging and discharging a secondary battery and the jig including the same

A battery fixing part included in a jig for charging and discharging a secondary battery, comprising:

• a conductive unit for contacting an electrode lead of the secondary battery to flow current therein;
• a pressing unit for pressing the electrode lead for the conductive unit to be in tight contact with the electrode lead of the secondary battery;
• and
• a pair of fixed blocks installed on an upper surface of a main body and disposed side by side at an interval,
• wherein each fixed block includes a fixed hole,
• wherein the pressing unit comprises a pressing bar for operating the pressing unit, a compressing plate to contact with the electrode lead, and a lifting unit connecting the pressing bar and the compressing plate, rotation axes protruding from the pressing bar, and the pressing bar is operated for the compressing plate to descend vertically to be in tight contact with the electrode lead in all area of the compressing plate with a same pressure simultaneously,
• wherein each of the rotation axes is inserted into one of the fixed holes and is rotatably coupled to the fixed block,
• wherein the pressing bar is pivotally rotated around a horizontal rotation axis disposed on a center of the pressing bar,
• wherein the lifting unit is connected to the pressing bar by a pin and is moved in the vertical direction by pivoting motion of the pressing bar, and
• wherein the compressing plate is moved vertically in a direction depending on a vertical movement of the lifting unit.
