Abstract

<P>PROBLEM TO BE SOLVED: To provide a winding structure of transformer where a forward/backward direction of enameled wire is easily recognized without the need of referring to a drawing when the enameled wire is wound around a bobbin, the direction of route of winding the enameled wire from a starting-side pin to the bobbin and the direction of the route from the bobbin to a finishing-side pin are easily found out, so that a mistake in recognizing the starting-side and the finishing-side of the enameled wire wound around the bobbin is surely prevented, thereby preventing the breakage of a set. <P>SOLUTION: According to a winding structure of transformer, an enameled wire 20 is wound around a bobbin 24 through a groove shaped route 23 from a pin 22 on a starting side of transformer 21, and then is attached to a pin 26 on a finishing side after passing through a groove shaped route 25 from the bobbin. Several parts of the enameled wire are colored with different colors 20a and 20b, each indicating a forward direction and a backward direction. The groove shaped route through which the enameled wire passes from the starting-side pin to the bobbin is designed in such a way that the width of route at the starting-side pin is made wider and that of the bobbin-side narrower. The groove shaped route through which the enameled wire passes from the bobbin to the finishing-side pin is designed in such a way that the width of route at the bobbin side is made wider and that of the finishing-side pin narrower. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  In the present invention, an enameled wire is wound around a bobbin from a pin on the lower side of the transformer via a groove-shaped path, and then the enameled wire is attached to the finish-side pin from the bobbin via another groove-shaped path. The present invention relates to the winding structure of the transformer.

  In general, if there is a mistake in the start and finish of the winding of the transformer, there is a problem that if this transformer is mounted on a real machine, the voltage becomes abnormal and the set may be destroyed.

  The first prior art is shown in FIGS. As shown in FIGS. 5 (a) and 5 (b), this conventional insulation-coated conductor direction indication structure is a transformer including a plurality of insulation-coated conductors 105 wound around a core. By providing a direction indicator 106 indicating one of the axial directions on the outer surface of 105, the winding direction, the winding start end and the winding end end of the insulating coated conductor 105 are clearly shown. (For example, refer to Patent Document 1).

However, in this case, since the winding direction of the insulation coated conductor 105 is not provided in the core, there is a problem that it cannot be understood without looking at the drawing before the insulation coated conductor 105 is wound.

  The present invention has been made in view of the above-described conventional problems, and when the enamel wire is wound around the bobbin, it is not necessary to look at the drawing, and the front-rear direction of the enamel wire can be easily understood, and the enamel wire is connected to the start side. The direction of the path from the pin to the bobbin and the direction of the path from the bobbin to the finish side pin can be easily understood, and the start and finish of the enamel wire wound around the bobbin of the transformer can be surely prevented. An object of the present invention is to provide a winding structure of a transformer capable of avoiding destruction of a set.

  The present invention has been proposed in order to solve the above-mentioned problems, and the invention according to claim 1 is characterized in that an enameled wire is wound around a bobbin via a groove-shaped path from a start-side pin at the bottom of a transformer. In the transformer winding structure in which the enamel wire is attached to the finish-side pin from the bobbin via another groove-shaped path, the enamel wire has a plurality of different colors in front and back to indicate the front-rear direction. The groove-shaped path through which the enamel wire is passed from the start side pin to the bobbin is formed so that the start pin side is wide and the bobbin side is narrow, and the bobbin to the finish side pin The groove-shaped path through which the enamel wire passes is characterized by being formed so that the bobbin side is wide and the finish pin side is narrow.

  The invention according to claim 2 is the invention according to claim 1, wherein the groove shape path on the pin side of the start is colored with different front and rear colors similar to the front and rear colors colored on the enamel wire, The groove-like path on the pin side of the finish is also colored with different front and rear colors similar to the front and rear different colors colored on the enamel wire.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a cover is provided in each of the groove-shaped paths.

  According to the first aspect of the present invention, the front and rear direction of the enamel wire can be easily understood because the enamel wire is colored with a plurality of different colors in order to indicate the front and rear direction. Furthermore, the groove-shaped path through which the enamel wire passes from the start side pin to the bobbin is formed so that the start side pin side is wide and the bobbin side is narrow, and the enamel wire is passed from the bobbin to the finish side pin. The groove-shaped path is formed so that the bobbin side is wide and the finish-side pin side is narrow, so the groove-shaped path for winding the enamel wire from the start-side pin to the bobbin and the groove from the bobbin to the finish-side pin The direction of the path of the shape can be easily understood without looking at the drawing. Accordingly, it is possible to surely prevent the start and finish of the enamel wire wound around the bobbin of the transformer from being mistaken, and avoid breaking the set.

  According to the second aspect of the present invention, the pin-side channel on the start side is colored with different front and rear colors similar to the front and back different colors colored on the enamel wire, and the pin-side groove on the finish side. Since the front and back are colored with different colors before and after the enameled wire, the direction of the path from the start pin to the bobbin and the direction from the bobbin to the finish pin Can be solved even more easily. In addition, it is possible to easily check whether the direction of the enamel wire passing through the groove-shaped path from the pin on the start side matches this groove-shaped path, and finish from the bobbin through the groove-shaped path. It is easy to check whether the direction of the enameled wire passing to the pin on the side matches the channel of this groove.

  According to the third aspect of the present invention, since the cover is provided in each groove-shaped path, it is possible to prevent the enamel wire from coming off from the path on each groove side and to protect the enamel wire covered with the cover. can do.
