Description

TECHNICAL FIELD

[0001] The utility model relates to cylindrical battery technical field, concretely relates to a support for positive and negative electrode same side cylindrical battery. BACKGROUND

[0002] The application market of cylindrical battery is more and more extensive now, and the voltage and capacity of single cylindrical battery are limited, so in practical application, it is usually necessary to construct battery pack by means of series and parallel connection of multiple battery cells to obtain larger capacity and voltage. When several cylindrical battery cells are assembled into a battery pack, the cylindrical battery needs to be installed and fixed by a support, and the series / parallel connection is realized by welding of the current-carrying sheet and the positive or negative electrode. The positive and negative electrodes of the cylindrical battery can be arranged at two ends of the battery or at one end of the battery, and a suitable support needs to be selected according to the arrangement of the positive and negative electrodes of the battery during assembly of the battery pack. The positive electrode of the cylindrical battery is usually the negative electrode of the battery, and the battery shell is the positive electrode of the battery. During welding of the positive and negative electrodes, the support needs to expose the welding areas of the positive and negative electrodes. At present, most of the integral battery supports are open-mold supports, i.e. they are specially designed and developed according to the requirements of a certain battery pack. Such supports usually have a fixed structure, and the positive and negative electrode welding areas are fixed. During assembly of the battery module, the arrangement of the busbars is usually fixed, and the busbar wiring cannot be adjusted. Therefore, the general applicability is low, and the open-mold cost is high and the open-mold cycle is long. There are also a few public mold supports. Although the general applicability of such supports is improved, it is difficult to realize welding of the cylindrical battery on the same side. Even if the support can realize welding on the same side, the positive and negative electrodes are completely exposed, which leads to poor insulation of the welding surface. SUMMARY

[0003] The utility model discloses a support for positive and negative electrode same side cylindrical battery, which overcomes the defects of the prior art and realizes insulation of the positive and negative electrodes by arranging the pole post stop edge and the fan-shaped partition plate. By selectively dismounting the fan-shaped partition plate, the positive electrode welding area can be selected, and the wiring mode of different busbars can be adjusted, thereby improving the general applicability of the support.

When the positive and negative electrodes are connected in series / parallel, the fan-shaped partition 5 at a certain position can be selected and removed according to the wiring requirement of the busbar 7, so as to realize the position selection of the positive welding area 8. The positive and negative electrodes are insulated by the pole stop 3 and the fan-shaped partition 5, and the positive welding area 8 is selected by selectively removing the fan-shaped partition 5, so as to realize the adjustment of different busbar 7 wiring modes.

[0025] In some embodiments, the circumferential side of at least 2 sectors of the sector baffle 5 is connected to the single-hole support 1. It should be noted that the soft connection of the utility model refers to the connection strength of the circumferential side of the sector baffle 5 to the single-hole support 1, which is lower than that when the sector baffle 5 is fixedly connected to the single-hole support 1, and the sector baffle 5 can be easily removed from the single-hole support 1 by damaging the connection part by the user. The connection method known to those skilled in the art that meets the requirements can be applied to the utility model, for example, the circumferential side of the sector baffle 5 is connected to the single-hole support 1 through the connecting bridge 6.

[0029] In some embodiments, two adjacent rows of single-hole supports 1 are arranged in a staggered manner.
