Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a power adapter with a novel cable management device. Background Technology

[0002] A power adapter, also known as a power outlet, is an electrical device used to connect electrical appliances to a power supply system. It allows users to plug in various electrical devices to draw power from the grid. The design of a power outlet ensures that current can be safely and reliably transmitted from the power source to the device, while providing necessary protection against electrical accidents. The internal structure of a power outlet mainly includes key components such as electrical contactors, conductive materials, insulating materials, and connectors. These components work together to ensure reliable power delivery and user safety.

[0003] However, most existing power adapters have a relatively simple overall structure, usually consisting of a power cord and a power strip. The power cord is also quite long, so it cannot be adjusted according to the actual length of use, resulting in poor aesthetics. Although there are now retractable power sockets on the market, their retraction direction is fixed and inconvenient to adjust. Furthermore, rotating them for storage is also inconvenient and not very practical. In addition, existing power strips have poor waterproof performance, posing a safety hazard. Utility Model Content
