Industrial plugs are connectors used in industry and agriculture to install power circuits, cables and wires of distribution equipment. They are mainly used to protect the normal operation of equipment, so that the equipment is not affected by the social environment, resulting in common faults of distribution equipment, and even short-circuit faults. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. 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 universality. IP54, that is, dustproof level 5: it cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. Industrial plug plays an important role in the use of mechanical equipment, and it must have its unique advantages and functions. Today, I will introduce three main functions of industrial plugs.The first function is the connection function, in which the plug force detection of industrial plug is the test of its performance test method. The connection function of connector is an important factor to determine the service life of components. Similarly, the structure and rolling friction index of connector contact parts will also affect the service life of industrial plugs.The next feature is the contact resistance, grounding resistance of industrial plugs and the compressive strength of electrical equipment. As industrial power socket is a kind of equipment to prevent leakage and short circuit caused by external problems, it must have the function of protecting electrical equipment.Compared with traditional digital products, what are the advantages of using connectors?Long ago, digital products were used to transmit data, so the process would be troublesome, and the data might be lost, which would be unfavorable for storage. At present, it is changed into a connector, which can directly return the transmitted data, saving the cumbersome transportation in the middle.At present, people prefer to use connectors because they simplify the equipment process of digital products, that is, the mass production process.
