This national standard two pole eight shaped tail Power cord strictly follows national electrical safety standards such as GB 2099.1 and GB 1002. It has passed 3C mandatory product certification and is suitable for domestic 220V/50Hz civilian and commercial power supply environments. It is a standard power transmission connection line for various double insulated electronic and electrical equipment, widely used for power supply access of household digital, small household appliances, lighting equipment and other products. It has the characteristics of convenient connection, safety and stability, and strong universality.

The input end of the product is a national standard two pole flat plug, and the pin size and inter pole spacing strictly follow the national standard specifications. It has universal interchangeability and can be smoothly connected to all wall sockets, mobile sockets, and extension sockets that comply with the national standard, avoiding adaptation problems and safety hazards such as virtual connection heating and loose insertion caused by non-standard plugs from the root. The plug adopts an integrated injection molding process, with a tight and seamless shell structure, and anti slip textures added to the side. When holding and inserting, it feels solid and not easy to slip; The tail integrates multiple circular anti bending wire protection structures, which can evenly disperse the stress generated by wire pulling and repeated bending, effectively alleviate the stress loss at the root of the wire, reduce the probability of internal copper wire breakage and sheath cracking, and significantly extend the overall service life of the power cord.

The output terminal is a standard IEC 60320 C7 octagonal power connector, commonly known as an octagonal socket. The interface design follows international standards and has strong adaptability, making it perfect for all devices with C8 octagonal input interfaces. The interface adopts a foolproof asymmetric design, which can only be inserted into the device in the correct direction to avoid poor contact and equipment damage caused by reverse insertion. The insertion and removal operation is smooth, and the holding force after engagement is moderate. It is not easy to loosen during normal use and can ensure the continuous stability of electrical connections. The tail of the connector is also equipped with anti bending wire protection structure, which is firmly connected to the wire and can withstand the pulling stress caused by daily plugging and unplugging. It is not easy to have wire core detachment problems after long-term use.

The conductive components are made of high-purity copper alloy substrate precision machining, and the pins and contact spring surfaces are uniformly nickel plated and treated with anti-oxidation. The conductivity is excellent, the contact resistance is low, and the temperature rise is stable under long-term rated load conditions. It is not easy to oxidize or ignite, and can continue to maintain reliable electrical contact performance. The insulation shell and connector housing are both made of flame-retardant engineering plastic injection molding, with electrical insulation strength meeting standards, excellent impact resistance, and high and low temperature resistance. They can quickly self extinguish in the event of external open flames, completely isolate internal live parts, and comprehensively prevent electric shock and fire risks. The supporting cable uses multiple strands of oxygen free copper stranded conductors inside, with low conductivity loss, stable current carrying capacity, moderate flexibility of the wire body, and can be bent and stored freely, making it less prone to dead bending damage; The outer insulation sheath is wear-resistant and anti-aging, and can adapt to various bending and pulling scenes in indoor daily use.The mainstream rated specification of the finished product is 10A 250V, which can meet the power supply needs of the vast majority of small and medium power Class II electrical appliances. Before leaving the factory, it undergoes multiple testing processes such as insulation withstand voltage, conductivity performance, plug and unplug life, and tensile strength. All performance indicators meet national standards and can maintain stable and reliable contact performance even after thousands of repeated plug and unplug operations. This power cord is widely compatible with various double insulated devices such as laptop power adapters, monitors, printers, projectors, digital camera Chargers, small speakers, desk lamps, decorative light strings, small appliances, etc. It can be used as an original factory power cord for complete machines, as well as for equipment maintenance and replacement, office consumables procurement, engineering wiring matching and other diverse scenarios. It is a standard power connection cable with a wide range of applications and strong universality in the field of civil low-voltage electrical.
