This Japanese standard three pole grounded power plug strictly follows the Japanese JIS C 8303 industrial standard for household plugs and sockets. It has passed the Japanese PSE electrical product safety certification and is compatible with Japan's domestic 100V/125V, 50Hz/60Hz dual standard civilian and commercial power supply networks. It is a standard power supply access component for a type of electrical equipment with a metal shell. With a complete grounding protection mechanism, reliable structural design, and stable electrical performance, it is widely used in power supply matching for various household appliances, office electronic equipment, and commercial appliances. It is also the core plug-in component for exporting electrical appliances to the Japanese market, cross-border electrical matching, and overseas engineering wiring.

The plug adopts a Japanese standard one round two flat three pole structure, with two parallel flat pins carrying the live and neutral wires respectively. The independent cylindrical pin is a dedicated grounding electrode, and the length of the grounding pin is significantly longer than that of the neutral pin. When inserting into the socket, the grounding circuit is first conductive, and when unplugged, it is finally disconnected, forming a safety logic of "ground first, power on later; power off first, ground off later". When the metal casing equipment such as refrigerators, washing machines, microwave ovens, and computer hosts have insulation damage or leakage faults, the grounding circuit can instantly introduce the fault current into the ground, avoiding electric shock accidents when the human body touches the metal casing, greatly improving the electrical safety factor of high-power electrical appliances. Both flat pins are designed with dedicated positioning circular holes at the ends, which can accurately fit with the positioning protrusions inside the socket. After insertion, they have sufficient retention force, effectively avoiding accidental contact and wire pulling that may cause the plug to fall off, ensuring the continuity and stability of power supply. The key parameters such as pin size and inter pole spacing are strictly in accordance with JIS standards, and have complete interchangeability with various compliant wall sockets and mobile plugs in Japan. They can be smoothly plugged in and out, avoiding safety hazards such as loose insertion, virtual connection heating, and poor contact caused by non-standard parts from the root.

The plug shell adopts integrated injection molding technology, with a tight and seamless overall structure. The shell shape conforms to the grip habits of the hand, making the insertion and removal operation easy and effortless; The shell end face is clearly stamped with rated parameters, certification marks, and polarity differentiation marks, fully complying with the labeling specifications of Japanese electrical products, making it easy to quickly identify product specifications and circuit polarity. The tail integrates a multi tiered anti bending and bending wire protection structure, which evenly disperses the stress generated by the pulling and repeated bending of the wire through multiple circular grooves. It can effectively alleviate the fatigue loss at the root of the wire, reduce the probability of internal copper wire fracture and outer sheath cracking, and significantly extend the overall service life of the matched Power cord. The plug is equipped with a stable locking wire fastening structure inside, which is combined with precision cold pressing technology to firmly bond the wire core and pins. The tensile strength meets the requirements of Japanese industrial standards, and it is not easy to cause problems such as wire core loosening and terminal detachment during daily dragging and bending use, ensuring long-term electrical connection stability.

The conductive pins are made of high-purity copper alloy substrate and precision processed into shape. The surface is uniformly nickel plated with anti-oxidation treatment, which has excellent conductivity, low contact resistance, and stable temperature rise under long-term rated load conditions. It is not easy to oxidize or ignite, and can maintain tight and reliable electrical contact performance after thousands of repeated insertions and removals. The insulation shell is made of engineering plastic that meets the Japanese standard flame retardant requirements. It has high electrical insulation strength, excellent impact resistance, and high and low temperature resistance. It can quickly self extinguish in the presence of external open flames, completely isolate internal live parts, and comprehensively prevent electric shock and fire risks.

The mainstream rated specification of the product is 15A 125V, which can cover the current carrying requirements of the vast majority of Class I electrical appliances. It is widely suitable for various electrical products with metal shells such as refrigerators, washing machines, air conditioners, microwave ovens, electric ovens, desktop computers, servers, printers, etc. It can be integrated into various finished power cords as an original factory supporting component, or used separately for customized wire processing, maintenance and replacement of old equipment, overseas engineering wiring matching and other scenarios. It is a standard power plug-in component with high safety level, strong compliance and outstanding practicality in the Japanese standard power supply system.
