Abstract: A transformer includes a main body, at least a rubber piece and a wire-guiding groove. The main body has a primary winding partition, several secondary winding partitions and two end portions. Several leads are disposed in either end portion. The rubber piece provides the buffer action, and it makes the secondary wire of the transformer which is pulled from several primary leads run closely and automatically fitted on the surface of the rubber piece and the primary end piece. The transformer used the rubber piece as buffer to avoid bending and breakage. The wire-guiding groove is formed in the primary end piece. The wire-guiding groove can guide the secondary wire to keep the secondary wire running closely and neatly on the lower surface of the primary winding partition.

Abstract: A transformer includes a main body and a wire. The main body has several winding partitions and two end portions. Several leads are disposed in either end portion and a buffer region is formed between the right end portion and the right-most winding partition. An intermediate area is disposed between the buffer region and the right-most winding partition. One end of the wire is connected to one of the leads and the wire passes the right end portion. Before the wire goes into the buffer region, the wire is folded for several times and then is twisted and rolled for several turns to make the wire thicker. Next, the thicker wire is wound around the iron core in the buffer region for several turns and then the thicker wire passes the intermediate area and goes into the right-most winding partition.
