Description

[Detailed description of the invention] The present invention relates to transformer winding, which eliminates the need for insulating the lead-out end of a coil, and further includes a terminal connected to the lead-out end.
The connection part of the leader wire or connecting parts such as diodes and their connection parts are locked and stored in the flange, thereby saving the need for insulation, making the structure more compact and easy to manufacture, and further improving the tensile strength of the leader wire part. It is characterized by:

Conventionally, in a transformer in which a primary coil and a secondary coil are wound in an overlapping manner, the secondary coil is first wound in an overlapping manner, and then a tape is wrapped around the outer surface of the secondary coil for insulation, and then the secondary coil is further wound.

However, in order to pull out the end of the secondary coil, it is necessary to insulate it from the secondary coil, and this is done using a separate insulating tape or the like.

That is, before winding the secondary coil, the lead-out end of the secondary coil is pulled out along the flange (generally referred to as a rising part).

) After insulating it by covering it with insulating tape, etc., the secondary coil is wound.

However, when the winding work is performed using a winding machine, there is a drawback that the work must be temporarily interrupted in order to insulate the drawn-out end.

Conventionally, when connecting terminals, lead wires, etc. to the coil lead-out end, a so-called press pod made of cardboard or the like is used on the outer surface of the coil between the upper and lower brim, and the connecting portion is bent and locked to the upper end of the press pod, and the outer surface It is wrapped with insulating tape to give it tensile strength.

However, they are very labor intensive to manufacture.

Furthermore, conventional transformers have been provided with parts such as small diodes installed depending on the purpose, but these are attached after the coil is wound due to manufacturing reasons, and they protrude from the coil part, resulting in an unsightly appearance. Furthermore, there is a drawback that it requires a lot of manufacturing effort.

The present invention eliminates the above drawbacks.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The winding frame 1 includes a winding part 2 and upper and lower flanges 3 and 4, and for example, the upper collar 3 is provided with a cut hole 5 close to the winding part 2.

Next, on the upper surface of the notch hole 5, there is provided a locking storage part A that locks and stores terminals connected to the coil, connecting parts of lead wires, or connecting parts and their connecting parts.

In FIGS. 1 and 2, the lock storage section A is constructed as follows.

That is, an upright wall 7 is provided at the end of the winding frame 1 on the side of the core mounting hole 6, a partition wall 8 is provided between the cut holes 5, and a partition wall 8 is provided above the partition wall 8 at an appropriate distance from the upper collar 3. A cover plate 9 is provided from the upright wall 7, and a cover plate 10 is provided at both ends of the cover plate 9 at an appropriate distance from the upper flange 3. Fold it and further fold it inward to form a U-shaped portion 12.

In this embodiment, after winding the primary coil, the cut hole 5 is
If you pull out the winding start end and the winding end end, you can wrap the insulation tape around the outer surface of the secondary coil and immediately start the secondary coil without insulating the area between the pulled out end and the secondary coil (conventional rising part). When a coil can be wound and a terminal, lead wire, etc. is connected to the lead-out end, the connecting part If stored in the U-shaped portions at both ends of the connector, the connecting portion X will be bent to engage the cover plates 1 and 0 and the upper flange 3, and will not protrude beyond the upright wall 7 and its U-shaped portion 12. Insulation with the core is also ensured.

In this embodiment, the cover plates 9 and 10 are provided with an appropriate interval between them, but this has the effect of making the connection work easier by pulling out the end of the leader line between them. It is sufficient to store it between the cover plate 9,1/O and the upper collar 3.

3 and 4, its structure is almost the same as that of the embodiment shown in FIGS. It is constructed so that the lead wire connected to the lead-out end of the secondary coil can be pulled out, and since the partition wall 8 is eliminated, it is also possible to store a diode etc. between the upper flange and the cover plate. be.

Note that the various embodiments described above may be provided at opposing positions on the collar.

As described above, according to the winding frame of the present invention, it is possible to eliminate the need for insulating the lead-out end of the coil, and to connect terminals connected to the lead-out end, connection parts of lead wires, connecting parts such as diodes, and their connections. The part is locked and stored in the flange, saving the need for insulation.
Furthermore, it is compact and easy to manufacture, and has the effect of improving the tensile strength of the leader line portion.
