In 2016, there was a term that was very popular on mobile phones. Almost all Almost all mobile phones will mention it. Speaking of this, we should have guessed that the term is: type-c interface, which is full name: usb type-c. Everyone must have heard of this term, but most people's understanding of this interface may only be superficial, and the channels of understanding may also be limited to some promotion by mobile phone manufacturers. So let's introduce this interface in detail below.

1、 What is the USB type-c interface

The USB type-c interface is a type of USB interface. There are currently four main types of USB interfaces:

1. USB type-a, which is the most common USB interface we use, is mainly used on computers, chargers, mice, keyboards, USB drives, and other devices.

2. USB type-b, this type of interface is mainly used on devices such as printers, and it is not common to have a type-a interface.

3. Micro-b, we have all seen this type of interface, which is the interface for mobile phone chargers.

4. USB type-c, which is our main character today, is the development trend of USB interfaces in the future.

2、 Features and advantages of USB type-c

The most obvious feature of USB type-C is its support for blind insertion on both sides. With this feature, mothers no longer need to worry about the wrong direction of the USB drive.

The advantages of USB type-c mainly include the following:

1. Supporting high current and high voltage charging can help improve charging speed. It can be said that the type-c interface is designed for fast charging technology, and there will definitely be more and more fast charging technologies for USB type-c interfaces in the future.

2. Support bidirectional power supply, using the USB type-c interface can charge the device itself and power external devices. (This way, we can achieve series charging by connecting different devices in series with a USB type-C interface cable.).

3. Strong scalability, USB type-c can transmit audio and video signals, so it can be extended to various audio and video output interfaces, such as HDMI, DVI, and VGA interfaces (in simple terms, it can be used as HDMI, DVI, and VGA interfaces, so as long as there is a USB type-c interface cable, there is no need to buy some HDMI, DVI, or VGA interface cables).

The Relationship between USB Type-C and USB 3.1

Nowadays, most people have a vague boundary between the words USB 3.1 and USB type-c. Believing that USB 3.1 and USB type-c are the same concept (mainly due to some mobile phone manufacturers intentionally confusing the concept). First of all, let's talk about what USB 3.1 is.

USB 3.1 is the latest USB transport protocol, which is

Developed by the USB IF Association. There are mainly several types of USB transmission protocols:

1. USB 1.0

2. USB 2.0

3. USB 3.0

4. USB 3.1

5. Thunderbolt interface, developed by Apple itself, has the fastest transmission speed.

The main difference between these transmission protocols is the transmission speed. USB 1.0 and USB 2.0 are relatively old transmission protocols with relatively slow speed. At present, the most widely used are USB 3.0 and USB 2.0. The laptops, U disks, Portable storage device and other devices we usually use are generally a combination of USB 2.0 and USB 3.0.

The relationship between USB 3.1 and USB type-c

After reading the introduction to USB 3.1, you must know that these two concepts are actually different things, and there is no relationship between the two.

USB 3.1 is a transmission standard, while USB type-c, to be precise, is an interface standard (interface type). So, the USB 3.1 protocol can support USB type-a, USB type-b (micro USB), and the latest USB type-c interface types. The USB type-C interface can also use transmission protocols such as USB 2.0, USB 3.0, and USB 3.1.

At present, some mobile phone manufacturers intentionally promote the idea that phones using the USB Type-C interface have fast transmission speeds. This view is incorrect, as only Type-C interfaces using the USB 3.1 protocol have faster transmission speeds.

The Prospects of USB Type-C Interface

It is obvious that the USB type-C interface will be the standard for future interfaces, and this type of interface will definitely be widely used.

1. Widely used in fast charging technology as a carrier (supporting high current and high voltage charging, which determines its application).

2. Unified interface type, due to its powerful scalability and support for transmitting audio and video signals, it can completely replace interface cables such as HDMI, DVI, VGA in the future, which can help us get rid of various transmission lines in our lives. And it can also liberate electronic products such as laptops and tablets, making them even lighter and thinner.

However, it will take a long time to popularize this type of interface, as there are various interfaces mixed in the market, including various adapters, peripherals, accessories, etc. Many people are unwilling to touch the interests of this market.
