In our daily life, the USB cable interface is used most. A variety of appliances are now common USB fast charger interfaces. U disk is also more frequently used. For example, one end of our cell phone charging cables is a USB cable interface. And our computer mouse is also a USB cable interface. The top of the router we often use also has a common USB cable interface, and the charger of the mini usb cable fan is also a USB cable interface.
In our daily life, we use USB fast chargers in particular a lot of places. Due to our improper use or high frequency of use, the USB cable interface is particularly prone to loosen or break down. If the USB cable interface is loose or broken, don't throw it in a hurry. Generally, the home data cable has a mobile phone connector at one end and a USB cable interface at the other end. Both the charging data cable and the data cable are the same type of USB cable interface. Figure out its interface, we will be easy to handle it.
First of all, we have to figure out what these four lines represent, how are they positive and how are they negative. After we studied it carefully, we found that whether it is the USB connector of the U disk, the USB connector of the data cable, or other types of the USB cable connector, the data distribution cable is similar.
We not only need to understand the structure diagram of the data cable and USB fast charger connector, but also need to understand the four color small cables contained in the data cable. How should they be connected? What do they represent respectively?
Generally, there are four colors inside the data cable:
Red: The red wire is generally connected to the positive side of the circuit according to our daily habits.
White: The negative wire connected to the data is generally ranked second.
Green: The positive wire connected to the data is generally ranked in the third position.
Black: This wire is connected to the negative pole of the wire and is generally placed at the bottom.
Most of the USB cable interfaces we currently use on the market use surface soldering technology. In the process of use, users often insert the interface backward, use excessive force, or use it improperly. These behaviors can cause the interface shift or indentation, then lead to poor contact of our data USB cable interface.
