In modern society, we often use a variety of electrical equipment, and the use of these devices can not be separated from the socket and power plug, and the national standard plug is currently in line with China's national standards of a universal power plug. Below, we will be from the definition of the national standard plug, structure, features and other aspects to explore the knowledge of the national standard plug.

First, the definition of the national standard plug

National standard plug refers to a kind of universal power plug that meets the national standard, that is to say, the plug used in the whole country must meet the national standard, so it needs to pass the ISO international standard certification and testing before it can be introduced into the market.

Second, the structure of the national standard plug

The national standard plug is divided into two parts: plug and socket. The plug has two or three pins, usually used to connect the current, electrostatic shielding and ground respectively; the socket has a corresponding number of jacks and paired electrodes to match the corresponding plug pins. In addition, the base of the plug is equipped with a brake pad, can be automatically disconnected from the power supply when the plug is pulled out to ensure the safety of use.

Third, the characteristics of the national standard plug

1, the national standard: in line with national standards, can ensure the safety and stability of use.

2, significant marking: plugs and sockets have significant voltage, current, plug type and other markings.

3、Excellent material: plugs and sockets are made of high quality engineering plastics, which have the characteristics of fireproof, anti-leakage and high temperature resistance.

4、Reasonable structure: the structure of plugs and sockets is reasonably designed, the number and arrangement of jacks are even, easy to plug and unplug.

five, Application of GB plugs

GB plugs are widely used in many fields, such as household appliances, electrical equipment, medical equipment, mechanical equipment and so on. In home use, we use GB plug price to connect TV, refrigerator, computer and other electrical appliances, in the industrial field, GB plug is widely used in motors, inverters, control cabinets and other equipment.

Sixth, the development prospects of GB plugs

With the rapid development of China's electrical equipment industry and the country's strict requirements for product quality and safety, GB plug manufacturers as a universal power plug will be more widely used and developed. In the future, with the rapid changes in science and technology and the fierce competition in the market, the national standard plug will also continue to carry out technological upgrading and innovation to meet the needs of different users.

In conclusion, as a kind of universal power plug, GB plug has been widely used in many fields with its features of conforming to relevant standards, reasonable structure and excellent material. At the same time, the national standard plug will also be more widely developed and applied with the continuous development of science and technology and the public's increasing demand for electrical safety.
