めに必要な高さhbが十分でないと端子がぐらつ
くという欠点もある。 As shown in FIG. 1a, the structure of a conventional thin transformer is that an L-shaped terminal 2 is embedded in the periphery of a winding frame 1, a winding 3 is wound around the winding frame 1, and the winding 3 is The lead wire 4 drawn out from the required part passes through the lead wire draw-out port 1a provided in the winding frame 1, and is wound two to three times around the lead wire binding part 2a of the terminal 2 and connected by soldering to the magnetic core. 5 is inserted into the winding frame 1 and tightened with a magnetic core clamping fitting 6. Mounting part 2 of the terminal 2
b is inserted into the component mounting hole of the printed board, attached to the printed board, and required connections are made. and,
Both the lead wire binding part 2a and the mounting part 2b are connected to the magnetic core 5.
It is located at the lower side in the figure, and is embedded and fixed to the peripheral edge of the winding frame 1. As shown in the side view of FIG. 1b, the height H of the winding frame 1 is the height H1 of the part where the terminal 2 is embedded, the height H2 of the part corresponding to the thickness of the magnetic core, and the winding 3 . It becomes the sum of the parts H 3 corresponding to the winding thickness of . The height H 1 of the part where the terminal 2 is embedded is structurally larger than the winding thickness H 3 of the winding 3, and therefore,
There is a drawback that the overall height H cannot be made small. FIG. 1c shows an enlarged cross-sectional view of the embedded portion of the terminal 2. In the same figure, the height H 1 of the embedded part is the height h a required for the escape of hot gas during printed board soldering, the height h b required for fixing the terminal, and the height h b required for fixing the terminal. The height h c corresponding to the diameter, the height h d required for connecting and soldering the lead wire, and the distance h necessary for insulating the lead wire 4 from the magnetic core 5 and the clamping fitting 6. The total height of e and e is required. Therefore, it is difficult to reduce the height H1 , resulting in the above-mentioned drawbacks. In order to reduce the overall height H, the thickness of the winding is increased to the height H 1 of the embedded part (increasing the number of turns of the winding), and the height H 2 is reduced by thinning the magnetic core.
It is also possible to make it smaller, but this has the disadvantage that the characteristics of the transformer are sacrificed. That is, there is a drawback that it becomes difficult to create a high-performance transformer. Furthermore, there is also a drawback that if the height h b necessary for fixing the terminal is not sufficient, the terminal will wobble.

ない。 FIG. 2a shows a perspective view of an embodiment of the present invention.
In the figure, reference numbers 1 and 3 to 6 respectively indicate the same elements as shown in FIG. 1, and reference number 7 indicates a terminal disposed through a hole provided in the thickness direction of the magnetic core 5. Reference numeral 8 is a supporting insulator that supports the plurality of terminals 7 in common, and reference numeral 10 is an insulating plate for insulating the lead wire binding portion 7a of the terminal 7 and the lead wire 4 from the magnetic core 5. Figure 2b
shows a side view of this embodiment. As understood from the figure, since there is no part of the winding frame 1 necessary for embedding the terminal 7, the height H1 can be made equal to the winding thickness of the winding 3. Therefore, there is an effect that the overall height H can be made smaller than that of the conventional one. In order to explain this in more detail, FIG. 2c shows an enlarged cross-sectional view of the penetrating portion of the terminal 7. A hole 5a penetrating the magnetic core 5 in the thickness direction is formed, a terminal 7 supported by a supporting insulator 8 passes through the hole 5a, and a lead wire tangle 7a projects through the hole of the insulating plate 10. An insulating tube 9 for insulating the terminal 7 from the magnetic core 5 is inserted into the hole 5a of the magnetic core 5. The terminal 7, the insulating tube 9, and the support insulator 8 may be integrally formed, and in this case, the terminal 7 can be firmly supported. Further, the support insulator 8 may be integrally formed with the winding frame 1. Furthermore, if the thickness of the supporting insulator 8 is made slightly smaller than the height H1 of the winding frame 1,
It can be used as an escape route for hot gas when soldering the transformer to a printed circuit board. Furthermore, even if the length for fixing the terminal 7 is not particularly considered, the thickness of the support insulator 8 alone can generally provide sufficient fixation and support, and the terminal will not wobble. Further, unlike the conventional case, the height corresponding to the terminal diameter (height h c shown in FIG. 1c) is not required. In addition, sufficient insulation between the lead wire tangle 7a and the lead wire 4 and the magnetic core 5 can be obtained by the insulating plate 10 , so the distance can be shortened . A portion has been appropriated. It is sufficient that a portion of the height H3 is also used for the tangled portion 7a of the lead wire. In summary, the height H of the winding frame 1 can be suppressed to the sum of the winding thickness (H 1 + H 3 ) and the magnetic core thickness H 2 required for the electrical performance design of the transformer. and does not require extra height for terminal mounting. Therefore, as described above, it is possible to obtain a thin transformer having a structure in which the height of the transformer is smaller than that of the conventional transformer. In order to make it easier to understand the structure of the transformer of this embodiment described above, the third
The figure shows a perspective view of the magnetic core 5 used in this example,
FIG. 4 shows a perspective view of the terminal 7, supporting insulator 8, and insulating cylinder 9. As shown in FIG.
A hole 5a for inserting the terminal 7 and the insulating tube 9 is formed on one side. As shown in FIG. 4, four terminals 7 are implanted perpendicularly to the support insulator 8 together with the insulating cylinder 9. The tip of the terminal 7 constitutes a lead wire binding part 7a, and the other end constitutes a mounting part 7.
constitute b. FIG. 5 is a perspective view showing the insulating plate 10, in which four holes are made through which the lead wires 7a of the terminals 7 are passed. Then, winding 3 is placed on winding frame 1.
, insert the magnetic core 5, tighten the circumference with the magnetic core clamping fitting 6, and insert the terminal 7, supporting insulator 8, and insulating tube 9 into the hole 5a of the magnetic core 5 as shown in FIG.
Insert the insulating plate 10 onto the facing surface of the magnetic core 5 and attach the lead wire of the terminal 7 to the exposed wire part 7a.
Install it so that it protrudes, and connect the winding lead wire 4.
is passed through the lead wire outlet 1a of the winding frame 1, wound two to three times around the lead wire tangle 7a of the terminal 7, and soldered to form the thin transformer shown in FIG. 2a. Each of the above constituent members is bonded to each other at required points. Further, it is possible to integrally mold any combination of two or more members in advance within a range that does not hinder assembly, and the combination is also free, and is not limited to the above-mentioned embodiments.

形成することができる。 Next, FIG. 6 shows another embodiment of the present invention. In this case, the winding thickness H 3 required for electrical characteristic design is very thin, and the lead wire binding portion 7 a is folded in the plane direction of the magnetic core 5 . This allows the lead wire 4 to be adjusted to the height H3 of the winding frame.
Since the lead wire can be wound and soldered around the tangled portion 7a within the range of 1.0, it is possible to form an extremely thin transformer.
また、磁心5はEE型、EI型、UI型、UU型、
LL型等いずれでも適用できる。 In addition, the magnetic core 5 is EE type, EI type, UI type, UU type,
Can be applied to any type such as LL type.

はない。 As described above, in the present invention, pin-shaped terminals are arranged in the thickness direction of the magnetic core, and the lead wire binding part and the mounting part of the terminal are located on opposite sides of the upper and lower surfaces of the magnetic core. Therefore, there is no need for extra height required for arranging terminals on one side of the magnetic core as in the conventional case. As a result, it is possible to provide a thin transformer that is thinner than conventional transformers, and its electrical characteristics do not deteriorate as a result.
