Views : Update time : 2021-08-20
Do you know the scientific name of their charging interface after using mobile phones for so many years? don't know. According to Xiaobian, there are three kinds of mobile phone charging interfaces, the old micro USB, the type-C from behind, and Apple's exclusive lightning interface. Before that, the charging interface of mobile phones continued to evolve and precipitate, and finally formed a tripartite situation. Come on, expose your age with weisp Xiaobian and claim the mobile phone charging interface you used in those years.
Circular interface
The earliest charging interface was round, and Nokia phones led the trend. The circular interface is large and small, and can be plugged in and out at will. However, because this interface has a single function, it is mostly only used for charging and cannot transfer files. With the circular design, in the long-term plugging process, it is easy to have problems such as loose interface and poor contact, so the circular interface gradually disappeared on the mobile phone.

Old long flat wide interface
The old long, flat and wide interface is mainly used in Samsung's anycall series mobile phones. It is an interface type exclusively customized by Samsung for its own mobile phones. At present, it is almost extinct. There are still some at home. The professor guesses that you should not be young.
The earliest iPhone to iphone4s series devices used a 30 pin dock interface, which was also a long, flat and wide shape. This interface has large volume, poor transmission speed, poor compatibility and openness.
Mini USB interface
This interface, also known as Mini USB, is T-shaped, small in size and excellent in anti misinsertion performance. Although many mobile phones are no longer used, some mobile hard disks, digital cameras, elderly machines, mobile POS machines and PSP game machines are still used. After all, they are small.
Micro USB interface
Micro USB interface is the next generation specification of Mini USB, which is a portable version of USB2.0 standard. It is compatible with USB1.1 and USB 2.0. It is smaller than Mini USB, with faster transmission speed and up to 10000 times of plug-in life and strength, but it can only be inserted on one side. Most mainstream flagship mobile phones now abandon this interface, and only some smart phones priced at 100 yuan and 1000 yuan are still in use.
Lightning interface
Starting with the iPhone 5, Apple has replaced the new lightning interface, which is smaller, more functional, and supports positive and negative insertion. This interface supports up to 2.4a current carrying capacity and the transmission speed is in the standard of USB2.0. Although the standard is a little low, the actual performance and experience are very good. At present, it is the standard interface of iPhone.
Type-C interface
After micro USB, type-C is another interface type widely used in Android smartphones. The type-C interface first appeared in Nokia n12015 and was used on Apple MacBook. LETV super phone 1 was the first to eat crab in China. Today, the type-C interface is already the standard interface for flagship mobile phones of major brands such as Huawei, Xiaomi and oppo, which has a promising future.
