Speaking of plugs, the poor quality of sockets and converters is an important cause of fire. 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. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. The quality problems of small plugs and sockets and converters will pose a serious threat to consumers and property safety. But what is an industrial plug? An industrial plug is just a simple connector. Your suppliers and customers connect to a plug and a plug, and then plug it into each other. Generally, industrial plugs and mating connectors are used. Industrial plugs and sockets, also known as power sockets, iec309 plugs and sockets and European standard (European type) plugs and sockets, are widely used in industrial power distribution because of their waterproof and dustproof functions. Mainly used for power connection, input and distribution. There are many places where industrial plugs and sockets can be used, and I will briefly talk about them below. 1. Injection molding machine/extruder 2. Audio and video lighting equipment and engineering 3. Power generation equipment 4. Mechanical equipment: food machinery, mobile welding machine. 5. Cabinet industry 6. Industrial Automation Equipment Company 7. Packaging machinery (heat shrink packaging machine) 8. Construction projects: newly built factories (workshop renovation), subways, etc. 9. Distribution equipment (distribution cabinet, distribution box, etc.) 10. Air conditioning unit 1. Lighting fixtures 12、 Something something something 13、Something something something something 14. Energy generation (solar, wind, nuclear) 15. Parts processing 16. Mobile communication: special vehicles 17. Refrigeration equipment: Refrigerated containers (Port Authority), etc. 18. Measuring instruments 19. Machine tool industry
