Description

Technical Field

[0001] This utility model belongs to the field of charging piles, and specifically relates to a wiring fixing device after the charging pile inlet line. Background Technology

[0002] As the low-carbon economy becomes the main theme of global economic development, electric vehicles, as an important component of the new energy strategy and smart grid, and one of the globally recognized strategic emerging industries, will inevitably become a key focus for the future development of the automotive and energy industries. However, the electric vehicle industry is a complex undertaking, and electric vehicle charging is a crucial link. The lack of unified standards for chargers currently produced worldwide significantly hinders the development of the electric vehicle charging industry in the context of economic globalization.

[0003] There are various AC charging piles on the market that are compatible with electric vehicles, each with its own design philosophy, striving to meet the requirements of different users. Although the AC charging piles on the market can generally meet the requirements, their designs are not very clever. The waterproofing of the inlet and outlet cables poses a hidden danger, and there is a risk of water leakage when the cables are pulled, making the AC charging piles a safety hazard. The wiring is also too rigid, making it inconvenient for customers to install. Utility Model Content
