Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and relates to a high-tensile energy storage battery connecting cable. Background Art

[0002] At present, since energy storage cables need to be processed into wire harnesses first, plugs are generally made at both ends, and then installed and inserted between battery modules. During the production, installation, disassembly, and maintenance, the cables often need to bear the tension of plugging and unplugging, and the bending and tensile stresses near the fork joints are relatively large. The cables are prone to insulation cracking and conductor core breaking at the interfaces with the plugs.

[0003] For example, a utility model patent with an application number of CN202120841968.2 provides a 125°C tensile-resistant, heat-resistant, flame-retardant, and environmentally friendly energy storage cable, which includes a conductor assembly, an insulating sleeve sleeved outside the conductor assembly, and a sheath sleeved outside the insulating sleeve. The insulating sleeve is made of a 125°C environmentally friendly low-smoke, halogen-free, heat-resistant, flame-retardant polyolefin irradiated cross-linked insulating material, and the sheath is made of a 125°C environmentally friendly low-smoke, halogen-free, heat-resistant, flame-retardant polyolefin irradiated cross-linked sheath material.

[0004] In summary, some existing technical solutions still have problems of design redundancy in insulation temperature resistance, high cable cost, and deficiencies in tensile design, and there is a large room for improvement. Summary of the Invention
