Industrial plug and socket coupler is mainly divided into plugs, sockets, connectors, and equipment input socket four categories. Commonly referred to as industrial plug socket.

Industrial plug socket has the following features:

1. Safe and reliable

(1) this kind of product with shell color said rated voltage, such as blue on behalf of 220 v, the red represents 380 v, be clear at a glance, easy to difference, won't make a mistake.

(2) the diameter of the product, the number of different specification, grounding contact position each are not identical, only the same specification can splice, so as to prevent it.

(3) protection against electric shock. Plug in the socket grounding set longer than phase extremely, central plug set, this will ensure the plug plug in on phase before on earth, and finally, grounding as it is pulled out, use is very safe.

(4) high protection grade. There are IP44 splash proof, IP67 immersion type, etc. The body cannot touch the live parts not only, still can be used under different environmental conditions, to ensure safety.

(5) set upon elastic band. Ensure that after the bolt is tight, conductive good contact, long service life.

Holding device is (6), so that the plug socket after plug card each other tight to prevent fall off, greatly improve the reliability.

(7) cables are clamp device, able to grip the cable sheath, fixed will not be pulled off, use safety.

2. Durable

(1) mechanical performance is good, the shell is made of high quality nylon products, its high strength, impact resistance, not afraid of falling, or trampling. All of rubber and plastic with aging resistance, not only can be used with indoor, can also be used in outdoor, durable.

(2) heat resistant, resistant to burning. Shell and internal insulation parts with heat resistance, temperature can reach to 100 + 5 ℃, the important components tolerated (125 + / - 5 ℃; And flame retardant.

(3) use more resistant to pull out. Products such as rated current 16 a, pull out plug normal operating cycle number in more than 5000 times.

Conducting contact head (4) a (pin and plug set) temperature &production) more than 50 k, suitable for long-term use.

3. Strong commonality

Product by GB/T 11918-11919-2001 standard, it is equivalent to standard IEC 60309-1/2, fully in line with international standards. Therefore, this kind of products in the domestic and international general. At the same time, the specification variety, can satisfy all kinds of occasions and purposes.

These characteristics of industrial plug sockets, make it has high safety and reliability and generality. So also gradually be taken seriously in domestic, through years of continuous popularization and application, industrial plug socket has entered all walks of life, such as electric power, construction, ports, large construction machinery industry and modern. The manufacturer also from the initial development of several to several hundred now. At the same time, along with the development of science and technology, industrial plug and socket continuous innovation, a variety of quick installation technology has been applied on the plug socket, make it more convenient.
