The coil winding method according to claim 15, wherein the fixture is elastically moved to move the core with the front end, and the hanging body is disposed on the jig and is synchronously displaced with the fixture. A coil winding method for winding a wire on an iron core, comprising: providing an iron core having a plurality of welded seats at a flange portion of the wire end and a plurality of flange portions at the outlet end a welding seat, between the flange portion of the inlet end and the flange portion of the outlet end is a core portion for winding the wire; a jig is provided, located between the two welded seats of the core; The wire rod of the welded portion of the portion passes through the jig and is bent against the welded seat on both sides of the jig for the wire to form a solder joint there. The coil winding method according to any one of the preceding claims, wherein the jig is provided with a first hanging line portion and a second hanging line portion, and the wire around the jig A solder joint is formed around the first wire-hanging portion and the second wire-hanging portion, and a core outlet end flange portion therebetween. The coil winding method of claim 18, wherein the wire passing through the solder joint between the first hanging portion and the second hanging portion is staggered before passing through the solder joint, and then bypassed The first hanging line portion turns the original staggered upwardly inclined wire into an oblique position but abuts against the welded seat where the iron core is located, and passes around the second hanging line portion and then turns straight to the two hanging body. The coil winding method according to claim 18, wherein the wire wound around the first threaded portion and the second threaded portion is simultaneously blocked by the first rib and the second rib above it, The restraint is positioned at an appropriate height and is free from the first hanging line portion and the second hanging line portion. The method of winding a coil according to any one of the preceding claims, wherein the fixture comprises a nested top; the fixture is embedded between the core and the solder joint. Interval. The coil winding method according to claim 21, wherein the embedded top portion comprises a cushion protruding from the front of the fixture seat and a bracket protruding laterally in front of the cushion; The insert is embedded in the interval between the two core welded joints. The coil winding method according to claim 22, wherein the first hanging portion is formed in the insert, and the second hanging portion is formed on the cushion.
