The alternator stator assembly structure with outwardly extending wire is disclosed. The alternator stator assembly structure includes a stator, a rotor, a rectifier and a plurality of connecting components. The stator includes a plurality of conducting wires extended outwardly thereon. The rotor is passed through the stator. The rectifier is disposed on the stator and has a plurality of connecting portions. Each connecting component has a base and a constraining wall, and the base is engaged and electrically connected to corresponding connecting portion by concavo-convex engagement or screwing, and the conducting wire is fastened by clamping of the constraining wall for adjusting or welding conveniently, so that the stator and the rotor can connect electrically.
