Each cell 14 is provided therein with a pole group (not shown) of a conventional structure, which generally includes a positive electrode plate, a negative electrode plate and a separator, and the separator is coated on the surface of the positive electrode plate and/or the negative electrode plate to separate the positive electrode plate from the negative electrode plate to avoid a short circuit. Two bus bars 3 are arranged at the top of each pole group, and pole plates with the same polarity are connected in parallel by a single bus bar. The adjacent pole groups are connected in series in sequence through a bridge 4, and pole posts 6 penetrating through the slot covers are arranged on the two pole groups at the two most sides.

Theoretically, the bus bar 3 and the bridge 4 may be staggered in height, but from the standpoint of saving the amount of lead used, flush is the best choice. In one embodiment, the bus bar 3 and the bridge 4 are at the same height, the same height means that the bottom surfaces are flush, so that the junction between the two sides of the protruding portion 41 and the bus bar 3 is provided with a recess 43 for avoiding the two sides of the glue groove 21, and the depth of the recess 43 is about 1/2-1/3 of the thickness of the bus bar 3.
In one embodiment, the notch 12 is inverted-splayed, the included angle between the side edge and the horizontal plane is 15-30 degrees, the minimum width is 1-5 mm larger than the width of the busbar 3, the depth is 1.5-3.5 mm larger than the thickness of the busbar 3, and the notch 12 has enough space for assembling the concave sealing gasket 5.
The shape of the concave sealing pad 5 is the same as the shape of the notch 12, in which, in one embodiment, as shown in fig. 12, the concave sealing pad 5 includes a main body 51 and a plug portion 52, the thickness of the plug portion 52 is only half of the thickness of the main body 51, and the inner side of the corresponding notch 12 has a slot 14 matched with the plug portion 52. When assembled, as shown in fig. 3 and 10, the insertion portion 52 is inserted into the insertion groove 14, and the inner side surface of the notch 12 is completely abutted against the outer side surface of the main body 51 to fix the concave gasket 5.
In one embodiment, the maximum dimension of the opening of the concave sealing gasket 5 is 0.5-2mm smaller than the width of the busbar 3, the depth of the recess is 0.5-2mm smaller than the thickness of the busbar, after the assembly is completed, the protruding part 41 is flush with the upper edge of the partition 11, and the concave sealing gasket 5 is in sealing fit with the two side surfaces and the bottom surface of the busbar 3 after being extruded, in theory, the protruding part 41 can be higher than the partition 11, but the lead consumption can be correspondingly increased.
In one embodiment, as shown in fig. 9 and 10, the thickness of the main body 52 is the same as that of the partition 11, and both sides thereof are flush with the partition 11, and also flush in the height direction. The two sides of the protruding part 41 of the bridge 4 are also flush with the two sides of the partition 11, and in order to increase the strength of the protruding part 41, the root of the protruding part 41 is provided with a bevel 42.
In one embodiment, as shown in fig. 4-7, the front surface of the slot cover 2 is provided with a cover plate slot 27 and a terminal slot 26, the terminal slot 26 is used for fixedly mounting a wiring terminal, color fixing glue is filled in the terminal slot 26, and the pole 6 passes through the slot bottom of the terminal slot 26 and is welded with the wiring terminal.

In one embodiment, some of the bus bars 3 have a longer length, and the outer side of the ribs 21 has a recess 23 for avoiding the bus bars 3.
Since the protruding portion 41 is located at the notch 12, it is naturally also partially inserted into the glue groove 21, and the glue is solidified to seal the upper surface of the protruding portion and the groove cover 2, while the other surfaces of the protruding portion and the concave sealing pad 5 form a seal, so that the occurrence of liquid mixing between the single cells 14 can be prevented. Since the concave gasket 5 and the convex portion 41 are partially entered into the inside of the glue groove, the sealing can be completely performed by the glue, and thus the sealing between them and the separator may not be formed.
In one embodiment, in order to prevent the battery from sliding, the bottom surface of the tank body 1 is provided with anti-skidding ribs 13, and the anti-skidding ribs 13 are criss-cross to form a grid shape, so that the anti-skidding effect is further improved.
