Abstract

PURPOSE:To unnecessitate the coil spacer to be used for a secondary winding by a method wherein space is provided on a coil bobbin, another space is formed at the projected part to be used to secure a creeping distance, and the starting part and the finishing part of winding of a lead wire are wired in such a manner that they are hidden insaid space. CONSTITUTION:The coil bobbin to be used for a transformer has the protrusions 1a and 2 to be used to secure the spatial creeping distance between the primary and a secondary windings 3 and 7, and the primary winding 3 is wound around between the protrusions 1a and 2. Space 10a and 10b are provided on the protrusion 1a, and the starting part and the finishing part of the lead wires 5 and 6 are wound around a terminal through the space 10a and 10b. Subsequently, an insulating tape 4 is wound and the second winding 7 is wound thereon. According to this constitution, the lead wires 5 and 6 are hidden in the protrusion 1a, and the space and creeping distance between the primary and secondary windings 3 and 7 can be secured without using a coil spacer.

ペーサ８の上に２次巻線７が巻線されている。Conventional structure and its problems Coil bobbins used in transformers generally have convex portions as shown in Figures 1 and 2 in order to ensure the spatial creepage distance between the primary and secondary windings stipulated by safety standards. 1 and 2 are provided, and a primary winding 3 shown in FIG. 3 is wound therebetween. Thereafter, the insulating tape 4 shown in FIG. A secondary winding 7 is wound on the spacer 8 .

以上のようなトランスの構造では２次巻線用のコイルス
ペーサ８が必要でありトランスの材料費アップ及び工数

欠点があった。The transformer structure as described above requires a coil spacer 8 for the secondary winding, which increases the cost of materials and man-hours for the transformer, and has the disadvantage that the space factor of the coil also deteriorates.

サが削除でき安価なトランスを提供するものである。Purpose of the Invention The present invention provides a bobbin in which a winding start lead and a winding end lead of a primary winding are hidden in a convex part of the coil bobbin to ensure space and creepage distance between the primary and secondary windings. With this structure, the coil spacer for the secondary winding can be omitted, providing an inexpensive transformer.

The wiring is to be hidden. In this way, the pull-out lead can secure the space and creepage distance specified in the safety standards from the secondary winding.
Since the coil spacer for the next winding can be eliminated, the transformer can be manufactured at low cost.

距離が確実に確保することができる。This protrusion is integral with the bottle terminal portion 9, and spaces 1oa and 1ob are provided so that the lead-out leads at the beginning and end of winding can be wound around the bottle terminal. The winding start and winding end pull-out leads 5 and 6 are passed through the winding start and winding end so as to be hidden in this space and are wound around the bottle terminal portion. In this way, the lead wire is hidden inside the protrusion, and when winding the secondary winding 7 as shown in FIG. Space and creepage distance between lines can be ensured.
