This national standard two pole power plug is designed and manufactured in strict accordance with China's national electrical safety standards as a mains power access component. It is suitable for domestic 220V/50Hz civilian and commercial power supply systems and mainly provides standardized and stable power connection solutions for double insulated electrical equipment. It is a widely used basic plug-in component in low-voltage power scenarios and is widely matched with various products such as household appliances, lighting equipment, digital peripherals, and small electronic devices.

The design and production of the product fully comply with core national standards such as GB 2099.1 "plugs and sockets for household and similar purposes - Part 1: General requirements" and GB 1002 "Types, basic parameters and dimensions of single-phase plugs and sockets for household and similar purposes", and have passed China's mandatory product certification (3C certification). The key dimensions such as pin thickness, pin length, and center to center distance between poles are strictly limited by national standards. Products of the same specification have complete interchangeability and can be smoothly connected to all wall sockets, mobile sockets, and extension sockets that comply with national standards, avoiding safety hazards such as loose insertion, virtual connection heating, and poor contact caused by non-standard plugs from the root, and ensuring the basic safety of the power supply chain. The mainstream rated parameter of the product is 10A 250V, which can cover the current carrying requirements of the vast majority of small and medium power Class II electrical appliances, and has a wide range of adaptability.

In terms of structural design, the plug adopts the national standard two pole flat plug structure, with two conductive pins arranged in parallel and symmetrical, making it easy to insert and align, and the insertion and removal operation smooth and efficient. This plug corresponds to the power supply requirements of Class II electrical appliances and is suitable for electrical equipment with dual insulation protection and no need for grounding protection. It has a simple and practical structure and strong adaptability. The tail of the plug integrates a multi-stage anti bending and wire protection structure, which evenly disperses the stress generated during wire bending and pulling through multiple layers of circular grooves. It can effectively alleviate the repeated bending and damage at the root of the wire during daily use and storage, reduce the probability of wire core fracture and sheath cracking, and significantly extend the overall service life of the Power cord. The overall use of integrated injection molding technology, the shell structure is tight and seamless, the appearance is flat and smooth without burrs, and anti slip ribs are added to the side of the shell. When holding and inserting, the hand feel is solid, and the force is convenient and not easy to slip.

At the material and process level, the conductive pins are made of high-purity copper alloy substrate and precision stamped. The surface is uniformly nickel plated and treated with anti-oxidation, which has excellent conductivity, low contact resistance, stable temperature rise under long-term rated load conditions, and is not easy to oxidize or ignite. It can maintain reliable electrical contact performance for a long time. The insulation shell is made of flame-retardant engineering plastic injection molding, which has excellent electrical insulation strength and impact resistance mechanical properties. It 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 plug is equipped with a stable crimping and locking structure inside, which uses precision crimping technology to firmly bond the wire core and pins, with strong tensile strength. It is not easy to cause the wire core to loosen or fall off during daily dragging and bending, ensuring long-term electrical connection stability.

The core performance indicators of the finished plug, such as insulation resistance, electrical withstand voltage, contact temperature rise, and plugging and unplugging life, have all passed standard testing. Under normal rated conditions, it can operate stably for a long time and maintain a tight and reliable contact effect after thousands of repeated plugging and unplugging. This plug can be flexibly matched with various wires such as PVC insulated sheathed wire, Rubber sheathed wire, etc., to adapt to different usage environments: ordinary indoor scenes are matched with PVC wires, which are lightweight and easy to wire, suitable for home and office environments; In scenarios with frequent movement and relatively complex working conditions, rubber wires can be used for flexibility, bending resistance, and higher mechanical strength.

This two pole plug is widely compatible with various double insulated electrical products such as desk lamps, decorative lighting, power adapters, small kitchen appliances, audio-visual equipment, digital peripherals, decorative light strings, etc. It is a standard power access component for Class II appliances in the domestic market, and is also suitable for indoor engineering wiring, equipment maintenance and replacement, wire customization processing, DIY circuit assembly and other diverse application scenarios. It is one of the most widely used basic plug-in components in the low-voltage civil electrical field.
