Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a transformer used in consumer equipment.

0002

[Conventional technology]

There have been various types of transformer coil bobbins, but Of these, as shown in Figure 3, the winding section of the low voltage section and the winding section of the high voltage section are Some have a multi-segment structure in which the main body is divided by a plurality of flanges 20 and 21.

0003 In this case, in order to wind the high voltage side coil C1, the coil wire S1 at the beginning of winding must be The flange 22 is guided to the body 23 side through the groove 22a formed in the flange 22, and then the flange is The winding is started from the inner surface of the flange 22 to form a coil, and the coil is spaced apart from the flange 22 and arranged opposite to the flange 22. After winding a predetermined number of times between the inner first high pressure section flanges 20, Then, through the cut groove 20a formed in the inner first high pressure section flange 20, Then guide the coil wire to the next section, and in the same way, wind the wire a predetermined number of times to complete the coil. It comprised C2.

0004 Therefore, the coil wire F1 at the end of winding is connected to the first high voltage section flange 2. from the second high pressure section flange 21 side located further inside than the first The front outer flange is inserted through the guide notch 20b of the high pressure section flange 20. 22 side.

[0005]

[Problem that the idea aims to solve]

Therefore, the coil wire F1 at the end of winding does not pass over the coils C2 and C1. Therefore, in order to ensure insulation, the coil wire F1 and coil C2 at the end of winding are , C1, and whether the coil wire F1 at the end of the winding is outside because it crosses in the air. The protection of these people was an issue.

[0006] This invention was proposed in view of the above, and its purpose is to Prevents the coil wire from passing over the top of the coil, and prevents the coil wire at the end of winding. Eliminates the need for insulation treatment between the coil and the coil, and protects the coil wire at the end of winding from the outside. To provide a coil bobbin that does not require any countermeasures, is easy to process, and has a simple configuration. It is in.

[0007]

[Means to solve the problem]

In order to achieve the above purpose, the present invention divides the coil into multiple parts other than at both ends of the body. Multiple flanges are formed to divide the coil into high pressure and low pressure sections. and the high pressure section is divided into a plurality of regions by the flange. In a transformer equipped with a coil bobbin, the innermost part of the high voltage section The coil wire at the beginning of winding is wound in the area, and the area is reached from the outer flange. A guide groove for guiding the coil wire at the beginning of winding is formed in the other area up to , the coil wire is wound from the innermost region to the other region on the front side. It is characterized by its structure.

[0008]

[Effect]

In this invention, the order of starting the winding of the coil wire on the high voltage section side is Start winding from the innermost side, that is, the back side, and wind it sequentially toward the front, until the end of the winding. The element wire F can be immediately pulled out from inside the outer flange 2, and the winding is completed. The aim is to simplify the processing of the coil strands F.

[0009] In this case, the coil wire S at the beginning of winding is guided to the innermost high voltage section side. However, a guide groove 7 is formed on the body 4, and the coil wire at the beginning of winding is S is stored in the guide groove 7, and the coil wire S at the beginning of winding is protected. I have to.

【Example】

FIG. 1 shows one embodiment of the invention. 1 in the figure shows outer flanges at both ends of the hollow body 4. 2 and 3 are formed on the outer periphery of the body 4, for example. Two first and second high pressure section flanges 5, 6 are formed with a preferred spacing. has been done.

[0011] In this case, the first high pressure section flange 5 is separated from one outer flange 2. They are placed facing each other. In addition, the thick part 2a of one flange 2 has a starting point of winding. The kerf 2b for guiding the coil wire S to the body 4 side and the coil wire F at the end of winding. A cut groove or the like is formed to draw out the material to the outside.

0012 Furthermore, the outer periphery of the body 4 between the flange 2 and the first high pressure section flange 5 , the first and second high voltage parts are the winding start area of the coil wire S at the innermost winding start. A guide groove 7 is formed to guide the section between the flanges 5 and 6. Corresponding to the position of the groove 7, the first high pressure section flange 5 has a coil element inside thereof. A deep groove 5a for guiding the wire S is formed.

[0013] FIG. 2 shows an example of the guide groove 7, in which the guide groove 7 has a substantially L-shaped cross section and is bent. By inserting the coil wire S at the beginning of winding into the part 7a, the lower layer of the coil and the coil wire S are connected. The coil wire S can be protected by the inclusion of the coil bobbin itself between the upper There is no need to take insulation measures such as interposing an insulating tape for the coil C wound around the coil C. More preferable.

[0014] In this example, the case where there are two high pressure section flanges is shown. may be two or more, and in this case, the guide groove 7 can be designed to extend as appropriate. Of course.

[0015] Therefore, when assembling, the gap between the high pressure section flange 6 and flange 3 is As is well known, if a low voltage section coil (not shown) is wound around the low voltage section side of the good.

[0016] In addition, the high pressure section is the innermost first winding region with respect to the outer flange 2. and a second winding area on this side, and the coil wire S at the beginning of winding is divided into a flange. The kerf 2b of the shaft 2, the guide groove 7 formed in the second winding region of the body 4, and the first high pressure section guided to the first winding region via a cut groove 5a formed in the section flange 5, It is wound a predetermined number of turns between the first and second high pressure section flanges 5 and 6.

[0017] After winding the predetermined number of turns, the coil wire is wrapped around the first high voltage section flange 5. The coil wire F at the end of the winding is brought over the second winding area, and the coil wire F at the end of the winding is placed on the flange. The coil C may be constructed by winding a predetermined number of turns so as to end on the near side.

[0018] Then, the coil wire F at the end of winding is pulled out to the outside through the cut groove 2c of the flange 2. As with other windings, it is tied to the base of a predetermined terminal 8 implanted in the thick wall portion 2a. and soldered.

[0019] In addition, if you incorporate an iron core (not shown) into this coil bobbin 1, you can install a transformer. Obtainable.

[0020]

[Effect of the idea]

As described above, according to the present invention, the coil wire F at the end of winding is attached to the outer flange 2. Make sure that it is pulled out from the front side, so that the coil wire at the end of the winding does not cross over the coil. This has the effect of making the processing easier because there are no errors.
