Line concentration power adapter for notebook computer

Abstract

The invention discloses a line concentration power adapter for a notebook computer, which realizes the line concentration function on the basis of the function of the conventional ordinary power adapter, and has the characteristics of convenience in carrying, packaging and transportation, compact structure and high practicability. The power adapter is characterized by comprising a power adapter main body, a built-in winding device of the power adapter main body, a connecting line wound by the winding device and an alternating-current (AC) plug and a direct-current (DC) plug which are retractably and movably connected. When the power adapter is used, the AC plug or the DC plug can be stretched to a certain degree to be automatically positioned according to user requirements, and the connecting line can be wound and repositioned automatically only by pulling the AC plug or the DC plug lightly. The power adapter has a novel, simple, skillful and reasonable in structure, high practicability and reliability and is easy to implement.

Description

technical field [0001] The present invention relates to a power supply adapter, in particular, to a power supply adapter that realizes the hub function on the basis of the function of the existing ordinary power supply adapter, has the characteristics of being convenient to carry, convenient for packaging and transportation, and has a rigorous structure and strong practicability. Cord Laptop Power Adapter. Background technique [0002] The existing notebook computer market is thriving, with various styles, and the use of notebook computers has become increasingly common, but the fly in the ointment is that the power adapter of the existing notebook When using, the connecting wire and plug should be unfolded and connected with the corresponding interface, and the redundant connecting wire will be scattered everywhere, and when the user needs to store or carry the power adapter after use, the connecting wire should be wound into a shape. , although its connecting wire and plu...

Problems solved by technology

[0002] The existing notebook computer market is full of vigor and vitality, and various styles are available, and the use of notebook computers has become increasingly common, but the fly in the ointment is that the power adapter of the existing notebook computer is not equipped with a winding mechanism and does not have a line collection function. When using it, the connecting wire and plug should be unfolded and connected to the corresponding interface, while the redundant connecting wires are scattered everywhere, and when the user needs to store or carry the power adapter after use, the connecting wire must be wound into shape , although the connecting wire and plug can be wound together, they are separated from the main body of the power adapter, which still appear to be messy and not concentrated enough, and there is a lack of rigorous structure, which causes a lot of inconvenience to users.

Therefore, in view of the fact that the power adapter of the existing notebook computer does not have a hub function, with the continuous advancement of technology and the continuous upgrading of products, the power adapter of the existing notebook computer needs further improvement and innovation in order to adapt to the future notebook computer market. needs
