What Is a USB Socket?

The USB socket is a general-purpose socket that is safe and energy-saving and has a USB interface, and includes a socket body. It belongs to weak electric products, and the output voltage is about 5v.

USB socket

USB socket is a kind of universal socket with safe power saving and USB interface.

The application range is very wide, such as:
1. Audio and video products:

Contact resistance: Contact Resistance 30mm

Rated load: Rated Load 30V DC 0.5A

Insulation Resistance: 100M

Insertion and extraction force: Insertion and Extraction Force 3N ~ 20N

Withstand voltage: Withstand Voltage 500V, AC / min Electrical life: Life 5000 times

Temperature range: Temperature -20 ~ + 70

Many people are worried about the safety of this new type of electronic product, which is actually not the case. ^[1] USB sockets are weak electronic products. ^[2] The output voltage is only about 5v. A good USB socket has intelligent distribution Current function, so how do we choose a USB socket?
1. Look at the price. The cost of a USB socket with intelligent current distribution is naturally indispensable. These price standards can refer to the price of a large brand USB socket. If it is too low, you must consider its safety performance. After all, it is safe. First, remember not to be greedy, cheap, or fluke.
2. It is better to choose a USB socket with indicator light, which can show whether the contact is good, and whether the internal circuit is smooth, which plays a warning role in terms of safety. (Misunderstanding: the indicator light is not the automatic disconnection of the USB socket, the indicator light only indicates that there is normal power on when plugged in, whether the plug is inserted normally, not whether there is power on standby . The core type automatic on / off USB socket belongs Very few brands of patents, usually marked with automatic switching on and off)
3. It is best to choose a USB socket with a button or an automatic switch, so that the USB does not need to run for a long time, consume power, and generate heat (the details are described in detail in the current market types)

4. When using automatic on / off USB socket, select the automatic USB socket with automatic on / off or door switch.
5. The tightness of the USB socket is just right, it is not too tight if it is not loose, and the insertion and removal strength is acceptable.
6. It is better to choose a USB socket with PC fireproof material. ^[3]
7. The internal copper sleeve design should be adopted. The color of the copper sheet is purple-red, which is better, such as tin phosphor bronze and high-precision phosphor copper. ^[3]
