Description

Technical Field

[0001] The utility model relates to the technical field of battery connection, in particular to an anti-rupture soft connection structure for new energy batteries. Background Art

[0002] Flexible connectors are used for connecting new energy battery packs and related products. They are made of bare copper wire or tinned copper braided wire (stranded wire) through cold pressing. The copper busbar flexible connector's interface is formed using molecular diffusion welding technology in a single pass. The product features high quality, strong conductivity, high current tolerance, low resistance, and durability. Another type of flexible connector is a metal conductor with a hole cut into the connecting portion, a plastic insulating sleeve placed in the middle, and then folded to the desired shape.

[0003] 1. In the prior art, although the traditional soft connection structure can be folded according to the required shape, this structure has a complex process, especially the hidden danger of the plastic insulating sleeve being easily broken after folding. This has certain shortcomings, is not conducive to people's use, and cannot well meet people's use needs.

[0004] 2. In the existing technology, the traditional soft connection structure can be folded during use, which makes it easier for oil and dust to accumulate in the gaps of the soft connection structure. Therefore, the copper busbar and copper foil need to be cleaned before installation to ensure that there is no oil, dust and other impurities on the surface. However, it is inconvenient to clean, remove dust and oil multiple times. Utility Model Content

It can also effectively protect the copper wire fitted with the inner wall of the explosion-proof inner sleeve, thereby greatly improving the safety and practicality of the flexible connecting structure.

[0010] A further improvement of the technical solution of the present utility model is that the interior of the explosion-proof inner sleeve is filled with flame-retardant fiber, and the outer wall of the flame-retardant fiber is fitted and connected to the outer wall of the copper wire.

[0011] The above technical solution is adopted.

[0015] By adopting the above technical solution, the use of the hexagonal screw and the fixing device in this solution can fix the fixing device to the flange through the hexagonal screw. The eight sets of hexagonal screws greatly improve the stability of the fixing device.
