Abstract
PURPOSE: To accurately mould the terminal part of a transformer coil with resin without using an injected-type metal mould, by using a simple terminal mould which is made of metal and covers only the tap lead part of the transformer coil.
CONSTITUTION: On the way of winding a coil conductor 6, a tap lead 2 is extended out and a tap changing terminal 4 is fixed. The terminal mould 9, which is made of thin steel sheet having holes for moulding only the tap lead part with the resin containing a filler, is prepared. After the lead 2 is coupled to the terminal 4, the terminal mould 9 is fixed on the surface of the coil by a fitting metal 12 and the filler 10 such as polyester is filled around the lead 2. Then, the coil 1 is dipped together with the terminal mould 9 in the resin. The resin is heated and hardened while the coil 1 and the terminal mould 9 are revolved. Thereafter, the terminal mould 9 is removed, so that the terminal part which has good appearance and whereon terminal screws are accurately arranged is obtained.
