いう技術問題も生じた。 It has been known to use this type of tape-shaped electric wire as a winding wire in a small transformer such as a DC-DC converter. However, conventionally, the bobbin and base of the transformer have been integrally formed, which is often inconvenient when automating assembly. For example, when winding is to be automated, the fact that the base is formed integrally with the bobbin is inconvenient because the bobbin cannot be easily attached to the winding machine. In addition, the base interferes with the processing of the lead wires, resulting in an increase in the number of man-hours. On the other hand, if the flange and base at one end of the bobbin were both omitted, a technical problem occurred in that the winding would protrude from the bobbin, resulting in poor formability of the winding.

ツク材から形成されている。 When winding tape-shaped electric wires as the primary winding 11 and secondary winding 12 around the winding portion 6, the lead wire 13 is pulled out at the level difference surface 14 as shown in FIG. This prevents the tape-shaped electric wire from bulging at the part where it is wound. Lead wire 13 is 1
Only the first winding of the next winding 11 is shown pulled out to the front for explanation, and the others are omitted. Incidentally, the bobbin 1 and the base 2 are made of ordinary plastic material.

位置出し精度を向上させることができる。 The transformer of the present invention thus constructed can be wound around the winding section 6 of the bobbin 1, the lead wire 13 can be pulled out, and after all winding-related work has been completed, the transformer can be fitted into the base 2 and fixed. After the bobbin 1 is fixed to the base 2, the core can be easily attached to the bobbin 1 from above and below. Furthermore, a portion of the box-shaped support base 4 doubles as the bobbin flange, and the surface 19 which also doubles as the flange is only located between the non-open side surfaces as described above. This makes it easy to pull out the lead wire 13 straight along the outside of the non-open side surfaces and prevents the winding from shifting. Furthermore, the combination of the obliquely cut shape and the surface 19 prevents the tape-shaped electric wire from getting caught on the surface 19, making it easier to wind it around the bobbin 1.
The positioning accuracy can be improved.

脱するものではない。 The present invention as described above is not limited to the embodiments and has a wide range of applications. For example, although the winding portion 6 is formed into a rectangular tube shape, it may also be cylindrical. Although only one set of parallel plates 8 protrudes above the collar 7, they may be divided into two or more sets. Furthermore, the support base 4 of the bobbin 1 may be provided with one or more slits perpendicularly on the side surface which is not open so that it can be partially deformed when the support base 4 is fitted into the hole 17. None of these depart from the scope of the present invention.
