- the electrical connection between the first connector 131 and the electrode tab of the cylindrical cell C is maintained due to the insulating member 121 of the upper plate 120 of the tray. It can be.
- the tray upper plate 120 may further include the electrical characteristic measurer 140 if necessary.
- FIG 5 shows the hinge frame 111a and the first connector 131 included in the cell tray 100 according to the second embodiment of the present invention.
- one hinge frame 111a includes four hinge coupling parts S, and four first connectors 131 are hinged to each of the hinge coupling parts S. can know that
- FIG. 6 The structure of the cell tray 100 to which the configuration of the hinge frame 111a and the first connector 131 is applied is shown in FIG. 6 .
- FIG. 6 is a cross-sectional view and a plan view of a cell tray 100 according to a second embodiment of the present invention.
- the hinge frame 111a has four hinge coupling parts S, and the four first connectors 131 are hinged to the hinge coupling parts S, respectively, and the hinge frame 111a has the lattice shape.
- the four hinge coupling parts S are installed so as to face the diagonal direction of the lattice space formed by the partition walls 111, so that the first The connector 131 rotates up and down in a diagonal direction of the lattice-like space.
- the hinge frame 111a is positioned above the partition wall 111 and four first connectors 131 are hinged to one hinge frame 111a. Unlike the first connector 131 included in the cell tray 100 according to the first embodiment, the first connector 131 is hingedly rotated toward the receiving portion A located in the diagonal direction.
- the cell tray 100 according to the second embodiment can further secure the inner space of the tray body 110, , it can be seen that the usability has been improved.
