The invention discloses a connection structure of an outgoing line of a three-phase winding brushless motor and a winding method for the connection structure. The connection structure comprises a stator body, an insulating bracket and a patch board, wherein the stator body comprises a three-phase winding; each phase of the three-phase winding comprises at least two single windings; the insulating bracket is arranged at the top of the stator body; a metal leading-out terminal is correspondingly arranged between two adjacent single windings on the insulating bracket; the leading-out ends of various single windings are respectively arranged on the metal leading-out terminals; the patch board is arranged on the insulating bracket and comprises an insulating plate and three metal conducting plates; the three metal conducting plates are respectively arranged on the insulating plate and are electrically insulated with one another; a leading-out port is arranged on each metal conducting plate; and each metal conducting plate is electrically connected with the corresponding metal leading-out terminal on the insulating bracket respectively. According to the connection structure, the leading-out ends are not separated due to vibration; and according to the winding method for the connection structure, a worker can quickly and accurately identify the windings corresponding to the leading-out ends, so that the production efficiency is improved; and the qualified rate is ensured.
