This national standard three pole elbow power plug is designed and manufactured in strict accordance with China's national electrical safety standards as a mains power access component. It is compatible with domestic 220V/50Hz civil and commercial power supply networks and is the core connecting component for safe power transmission between various electrical equipment and power sockets. It is widely used in household appliances, office electronics, small industrial equipment and other products, and is the basic core component for ensuring electrical safety in low-voltage electrical scenarios.

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 pin size, inter electrode spacing, grounding structure, and rated parameters are all strictly regulated and limited. Products of the same specification have complete interchangeability and can be smoothly connected to all wall sockets and extension cords that comply with national standards. This fundamentally eliminates the potential electrical hazards and equipment damage risks caused by non-standard components' virtual connections, misconnections, and misconnections. The mainstream rated specification of the product is 10A 250V, which can cover the current carrying requirements of the vast majority of household and light commercial appliances, and has a wide range of adaptability.

In terms of structural design, the product adopts an L-shaped elbow integrated structure, which is more in line with the wall than a straight plug. After insertion, the wire extends smoothly along the wall, greatly reducing the space distance for the plug to protrude outward. It is especially suitable for use in confined spaces such as furniture, electrical appliances, cabinet gaps, etc., which can avoid the wire being in a forced bending state for a long time and effectively reduce the probability of wire root breakage and core breakage. The plug adopts a three pole flat insertion system, and the length of the grounding pin is significantly longer than that of the live and neutral wire pins, achieving a safety logic of prioritizing ground conduction and finally disconnecting when power is cut off; If there is a leakage fault in the supporting metal shell equipment, the fault current can be immediately introduced into the ground, greatly reducing the risk of personal electric shock. The three pins are arranged in a fixed polarity and have a dedicated foolproof structure. They can only be inserted into the socket in the correct direction, effectively preventing equipment charging, circuit faults, and other problems caused by zero fire reverse connection. The tail of the plug integrates multiple circular anti bending and wire protection structures, which evenly distribute the stress during wire bending and pulling through multiple grooves. It can effectively protect the root of the wire during daily insertion, removal, dragging, and storage, and 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 without burrs, and the grip and insertion feel is smooth and moderate.

At the material and process level, the conductive pins are made of high-purity copper alloy substrate through precision stamping processing, and the surface is uniformly nickel plated with anti-oxidation treatment. The conductivity is excellent, the contact resistance is low, and the temperature rise is stable under long-term rated load conditions, making it less prone to oxidation, sparking, overheating and other abnormalities. The insulation shell is made of flame-retardant engineering plastic through integrated 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 can firmly clamp the cable core and has strong tensile strength. It is not easy to cause the 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, all meet the standard requirements. It can operate stably for a long time under normal rated load and maintain tight and reliable contact performance even 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 meet the needs of different usage environments. It is widely suitable for household and office equipment such as air conditioners, refrigerators, washing machines, kitchen appliances, computer hosts, monitors, etc. It can also be matched with small power tools, commercial lighting equipment and other products. It is a standard power access component for circulating electrical appliances in the domestic market, and is also suitable for various application scenarios such as engineering wiring, equipment maintenance and replacement, and customized wire processing.
