Nowadays, many electrical products have realized automation, and their performance is getting stronger and stronger, which requires higher information processing ability. As the main component of information control system, CEE connectors are already difficult to use, so it is extremely urgent to develop the next generation connectors. Embedded socket is embedded in an integrated communication cabinet, which provides DC basic power for communication and data equipment in the same cabinet. It has certain universality at the same time. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. The connector is developing towards the trend of "miniaturization", "high-speed mobility" and intelligence. 1. development of miniaturization of connectors. Due to the development of electronic technology, the product performance is much stronger than before, and the volume is much smaller than before, which brings the advantages of small occupied area and convenient use. As products get smaller and smaller, cee connectors must get smaller and smaller. The trend of miniaturization is obvious. Now many connector manufacturers are actively researching and developing microconnectors. Second, high-speed mobility. This technology is mainly applied to wireless communication equipment, and has a wide application prospect. Third, research and application of simulation software. Through the computer and the corresponding three software tools such as autocad and pro/e, the product model and data storage are established, and the mechanical and strength characteristics of the product are simulated, thus reducing the risk of product development failure caused by unreasonable material selection and structural design, improving work efficiency and enhancing the competitiveness of enterprises. 4. Intelligent connectors. The application of automation technology is becoming more and more popular in industry, and the information exchange of various electric lines is characterized by large capacity and high frequency. Intelligent connector can detect intelligent signals during circuit transmission, so as to ensure that the plug is inserted in place before it starts to work, and to prevent the adverse consequences of excessive current burning caused by the plug being connected when it is not inserted in place.
