[0098] It is understandable that the orientation of the first direction X is not limited and can be selected according to actual use requirements, as long as it is ensured to be perpendicular to the height direction of the support member 200 along the first direction X.

[0099] It should be noted that, when the first direction X has multiple different orientations, the second direction Y has multiple different orientations. The orientations of the second direction Y are described below with examples in sequence.

[0100] In a feasible embodiment, when the first direction X is the length direction of the square frame connector 100, the second direction Y is the width direction of the square frame connector 100, that is, the second direction Y is perpendicular to the height direction of the support member 200, and the first direction X and the second direction Y intersect.

[0114] It should be noted that the liquid injection hole is communicated with the installation space 101 .

[0115] It is understandable that the injection hole is in communication with the installation space 101 , so that the electrolyte can enter the interior of the installation space 101 through the injection hole to meet the normal use of the battery.
