Abstract

PURPOSE:To eliminate that the molten dross of an exfoliated insulating film adheres to the boundary part between the end of a coil and an insulating film by a method wherein the end of the coil is pulled up to the outside of a molten solder from the position which is moved at a certain distance from the position where it has been immersed in the molten solder. CONSTITUTION:The end of a coil 5 is moved and immersed in a molten solder 23 inside a solder tank 22. Then, it is moved to the transverse direction. After that, it is pulled up in the upward direction or in the obliquely upward direction. Although the molten dross of an insulating film is floated on the surface of the molten solder 23, the molten dross does not adhere to the end of the oil 5 because the end of the coil 5 is pulled up by avoiding the molten dross; the end of the coil is coated with the solder. Thereby, it is possible to eliminate that the molten dross of the exfoliated insulating film adheres to the boundary part between the solder coating part at the end of the coil and the insulating film at the end.

As described above, the solder dipping method and apparatus for immersing a coil terminal in molten solder in a solder bath and coating the coil with solder at the same time as peeling off an insulating film are as follows. The end of the coil is pulled up to the outside of the molten solder in the solder tank from a position moved a certain distance from the position where immersion into the molten solder starts. Since the scum can be pulled up from a place where it is not floating, the molten scum of the peeled insulating coating does not adhere to the boundary between the solder coating at the end of the coil and the insulating coating at the end. Therefore, when the end of the coil is connected to another current-carrying part, the melted residue will not cause problems such as catching or disconnection. Since the length of the solder coating portion is stabilized, it is possible to connect it to other current-carrying portions with good dimensional accuracy.
