At present, the connectors on the market (i.e. industrial plugs and sockets) have the following four problems in practical use:(1) Not suitable for frequent or frequent operation;(2) It is more difficult to plug in and out, and the labor intensity is high;(3) Frequent plugging and unplugging will easily loosen and wear the female bushing shaft, which will lead to poor contact, increased current and heating. In severe cases, the three currents will be unbalanced, which will cause serious hidden trouble to equipment or electrical components, and at the same time, it will also be a potential danger to external electrical circuits that will cause fire due to increased current and heating;(4) Not suitable for live operation and load operation. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors. A switch is arranged between the weatherproof socket resistor and the electromagnetic switch, the fuse and the electromagnetic switch are connected with a power line, the power line is provided with a normally open switch of the electromagnetic switch, and the normally open switch of the electromagnetic switch is connected with the jack. Embedded socket is embedded in the integrated communication cabinet, which is a power supply device that provides basic DC power for communication and data equipment in the same cabinet. It also has certain versatility.After years of practice, I have mastered the skills to solve these problems, and found a correct way for the development of domestic CEE connectors.Cee connector adopts special design, which makes plugging and unplugging simple and clever. It breaks through the defects that the traditional industrial plug is difficult to insert and easy to loosen. It can be opened with a light press, which is effortless and reduces the burden. We added a fastening device at the end of the product. By tightening the external cable fastening bolt, the fastening device automatically and synchronously fastens the sealing ring, and automatically closes the connector back cover after unlocking, thus avoiding forgetting problems and being safe and reliable. The connector is made of special materials, which are different from the materials commonly used in the industry, have high strength and conductivity, and are dustproof and waterproof.At the same time, the special design greatly prolongs the life of the socket, greatly reduces the loss, and solves the problems such as the burning of socket motor equipment caused by unstable current. It solves the security problem, and at the same time, it also reduces the maintenance cost after your purchase, without worries.
