General type power adapter three -pin plug connecting wire, universal plug (1) is connected to wire (2) rear end, by three oversheath claddings heart yearn (8) in wire (2), three heart yearn (8) are live wire L respectively, zero line N and ground wire E, three heart yearn (8) are respectively by wire (2) back termination play, installation adjustable electrode fixing base (5) on universal plug (1) terminal surface, arrange respectively on adjustable electrode fixing base (5) telluric electricity field (4), zero line electrode (6) and live wire electrode (7). The service life of the different standard power adapter's of connector assembly wire pair general type, configuration optimization succinctly rationally compromises different standards, is showing reduction manufacturing cost, the inventory management of being convenient for, the plug is light and electrode contact is good, insulating ageing resistance can be good, resistantly draw, counter -bending, interference immunity good, convenience safe in utilization, durable, overall structure is succinct pleasing to the eye, the suitability is strong, is prolonged it is long.
