Brief history of the development of lamp plug and socket
Lamp plug and socket, is very common in our lives electrical accessories, all electrical lamp plugs and sockets are required to work up the bridge. Long ago, when the lamp plug socket has not yet appeared, when connected to the electrical, people can twist the wires on the power supply terminal, which is relatively insecure and complex approach. With large numbers of appliances, lamp plugs and sockets products are born.
With the continuous development of computer network technology, lamp plug and socket products also continues to develop, the beginning of the lamp plugs and sockets are black phenolic resin powder (i.e. jade powder) based, and later in order to improve their safety, some studies in the lamp plug socket added protection, therefore, a great variety of outlets there.
In recent years, in addition to the trend of development in terms of security, but also made great progress on the function. Large domestic enterprises developed PDU socket, Continental PDU, British PDU, GB PDU, etc., a variety of multi-socket PDU also came into being, a regular function switch, waterproof socket, there are new products such as lightning protection socket, competitiveness constantly improved.
In the same time, the rapid development of the domestic PDU products, foreign trade has constantly increased. Foreign products are slowly entering the domestic market, such as the British PDU outlet. PDU outlet has gradually become international; countries can use the product to become many different types of composite jacks countries. Ensuring international standardization, we must also protect the safety and reliability of products used by PDU.
With the rapid development of the computer industry, a large data center, computer room will be more, as the core of the engine room of the socket; the demand has greatly improved its distribution. Domestic construction standards for the number of sockets made a higher demand for lamp plug and socket type electrical accessories industry, China as the world's factory, but also the future of the producing countries, although there are a lot of problems, I believe that in the future, China's industry will certainly jack lamp plug forefront.
