This American standard NEMA 5-15R three hole female socket extension socket strictly follows the UL62 and NEMA electrical standards in the United States. It has passed UL safety certification and is suitable for 125V 60Hz civilian power supply systems in North America such as the United States and Canada. It is commonly used as an adapter for American standard power lines and as an output terminal for extension lines. It is compatible with all NEMA 5-15P American standard three pin Male connectors on the market and is widely used for temporary power supply adapters in office equipment, home appliances, digital products, and small industrial equipment. It is a highly versatile power adapter accessory in the North American market.

The socket adopts a standard NEMA 5-15R three pole open hole layout, with the upper circular hole as the grounding socket, and the lower two parallel flat holes corresponding to the live wire and neutral wire respectively. The hole size and inter pole spacing fully comply with the North American unified specifications, and can smoothly insert the American standard two flat and one round grounding plug. After insertion, the card position is tight and there will be no looseness, virtual connection, or detachment problems. The grounding hole combined with internal grounding spring can construct a complete grounding circuit for metal shell equipment such as refrigerators, computer hosts, printers, and power tools. When the equipment leaks electricity, it can quickly export the fault current, avoid the risk of electric shock, and meet the mandatory grounding safety requirements of Class I electrical appliances in North America. The metal spring inside the socket is made of high elasticity copper alloy stamped and formed, with nickel plating on the surface for rust prevention and oxidation resistance. It can be inserted and removed tens of thousands of times with strong clamping force, and the temperature rise is stable when powered on for a long time at full load, making it less likely to heat up or ignite.

The shell is made of integrated injection thickened flame-retardant PVC, which meets the V0 flame-retardant standard. It is impact resistant, high and low temperature resistant, and anti-aging. It is not easy to crack and deform after long-term indoor use. Multiple vertical anti slip ribs are designed on the outer side of the shell, providing sufficient friction and effortless grip when inserting and removing plugs; The output position is integrally formed with a buffer wire protection structure, with reserved buffer space inside to disperse the stress caused by wire pulling and bending, effectively preventing repeated cracking at the root of the wire and internal copper wire breakage, greatly extending the service life of the wire. Reserved heat dissipation holes in the shell can dissipate internal heat during load operation, reducing the risk of high temperature aging and adapting to long-term continuous power on scenarios. Internally, a lock wire crimping structure is used, with the wire tightly pressed against the conductive spring plate. Through North American standard tensile testing, daily dragging of the wire will not cause core loosening or power failure.

The supporting cable adopts multi stranded oxygen free copper stranded conductors with low conductivity loss and stable current carrying capacity. The outer layer is thickened with weather resistant PVC insulation sheath, which is flexible, wear-resistant, bending resistant, and oil resistant. It is suitable for various use environments such as offices, homes, and small workshops. Before leaving the factory, the finished product undergoes a complete set of safety tests, including voltage insulation testing, temperature rise load testing, plug-in durability testing, and wire tension testing. Only when all meet the standards can it be circulated in the North American market. The rated specification is 15A 125V, supporting power supply for various small and medium-sized household appliances and office equipment.Applicable scenarios cover both household and commercial fields: household can be converted to desktop computers, monitors, televisions, speakers, and small kitchen appliances; Adapt to office environments with printers, copiers, projectors, switches, and live streaming equipment; At the same time, it can be used as a replacement part for equipment maintenance, a matching mother base for cross-border American standard extension cables, and a temporary wiring adapter for exhibitions. Taking into account grounding safety, durable structure, and wide adaptability, it complies with North American electrical safety regulations and is an indispensable power adapter component in American standard power supply environments.
