Field of the Invention The present invention relates to an inverter transformer for a lighting circuit for a backlight for a backlight for liquid crystal display. [Prior Art] In recent years, the price competition of electric equipments such as liquid crystal televisions and personal computers has become increasingly fierce, and electronic components such as inverters mounted on liquid crystal monitors have been continuously required to reduce costs and cut zeros. The number of pieces. In order to cope with this requirement, a two-inverted inverter is used as the inverter transformer. As such an inverter transformer, for example, it is disclosed in the patent document. Patent Document 1: JP-A-2001-267156 (First) In the inverter transformer disclosed in Patent Document 1, two rod-shaped magnetic cores are inserted inside the bobbin for the primary winding around which the primary winding is wound, and the secondary windings are wound separately. In the stomach, two rod-shaped magnetic cores are used. With such a configuration, the high-frequency voltages of the outer two primary windings are boosted and applied to two discharge lamps connected to the secondary windings to turn on the discharge lamps. The inverter transformer disclosed in Patent Document 1 has a history of the open magnetic circuit structure, so that a part of the magnetic flux generated by the electromagnetic coupling of the primary winding and the secondary winding leaks to the outside of the inverter transformer. The problem of noise generated by the liquid crystal monitor due to the magnetic flux leaking to the outside. The present invention has been made in view of the above circumstances, and an object thereof is to provide a 1308350 capable of preventing externally In order to solve the above problems, the inverter transformer of the present invention is a transformer for outputting the alternating current input to the primary side, and then discharging it to the secondary side. , in the middle, is provided with: a winding bobbin with a primary winding and a secondary winding to V eight, the intermediate bobbin 'clamped between the two coil bobbins' and at least one of the cores has a bobbin a pair of cores of the magnetic core legs having at least the same number of the intermediate line skeletons; the magnetic cores are respectively inserted into the plurality of coil bobbins and the inner side of the inter-thread bobbin to abut the pair of magnetic cores, and are smashed Connecting a plurality of magnetic cores from a pair of 〜 〜 破 破 形成 形成 形成 形成 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; a plurality of winding flange portions that are divided and wound in the axial direction of the bobbin, projecting from the outer surface of the bobbin and arranged to be arranged in plurality along the axial direction of the bobbin; volume The flange portion is provided with a missing portion for guiding the end of the secondary winding wound on the bobbin to the terminal of the bobbin i, and the terminal for guiding the secondary winding is disposed at a plurality In the notch portion on the winding flange portion, the first notch portion (12w) is cut longer than the other missing portion (12v). In the case of such a configuration, the magnetic wrap is inserted into the wound primary winding. And a pair of magnetic cores of the secondary winding are butted to form a closed magnetic circuit connecting the bobbins. Therefore, the magnetic force generated by the primary winding and the secondary winding forms a magnetic circuit in the closed magnetic circuit, thereby The case where the inverter transformer leaks the magnetic flux to the outside is prevented. Therefore, it is possible to prevent noise and eddy current from being generated by various liquid crystal devices equipped with the inverted phase 1308350. In addition, in the case of such a configuration, from the beginning Winding to the end winding, the secondary winding can be wound sequentially in the divided area. Therefore, it is not necessary to reciprocate the secondary winding on the bobbin, and it is possible to prevent the end of the winding winding from being terminated by the end of the winding winding which has the largest potential difference. Therefore, the ends of the windings cause dielectric breakdown between each other, and as a result, the ends can be prevented from being short-circuited with each other. Further, with such a configuration, the end can be bundled on the terminal without applying an excessive electric power to the end of the secondary winding. Therefore, it is possible to prevent the end of the winding from being broken. According to another aspect of the invention, in the coil bobbin, both flange portions (i2f, i2g) located on both end sides of the bobbin are formed to have the same length in the left-right direction and the upper portion, and are protruded downward. Prominent than the length of the other three directions. With the present invention, it is possible to prevent the magnetic flux from leaking to the outside of the inverter transformer.

The tip end faces of the end core portions 24d, 24e of the core 24a and the core 24b The end faces of the end core portions 24d, 24e are on the outer side of the coil bobbin 35 In addition, the core end of each of the magnetic cores 2, the end faces of the 24h, 24g, and the respective core legs 2 of the core 24b, the end faces of the 2, 24g, are in the holes of the bobbin 12a. The inside of the hole 1 7a of the intermediate bobbin 16 and the hole 2d of the bobbin j 2b are in contact with each other, and the end core portions 24d and 24e and the core leg 24f of the magnetic cores 24a and 24b which are in contact with each other are The end faces of 24h and 24g were fixed with an adhesive. The magnetic body thus formed. The member 24 forms a closed ridge connecting the bobbins 1 2a, 1 2b, and 16 in a magnetic core member 24, and in the inverter transformer 1 ,, the voltage input to the primary winding is induced in the secondary winding. An electromagnetic coupling is formed between the primary winding and the secondary winding. Further, by the closed magnetic path formed between the respective bobbins 1 2t > 16 , the magnetic flux generated by the primary winding and the secondary winding wound around the bobbin turns 2a, 1 2b is in the closed magnetic path of the core member μ A magnetic circuit is formed inside. Because &, it is possible to prevent the magnetic flux generated by the primary winding and the secondary winding from being inverted and transformed! 1 0 outside the leak. Next, a method of manufacturing the inverter transformer 10 will be described. f First, one of the L-shaped terminals of the L-shaped terminal 31 is inserted into the terminal holes 4a of the four eight terminal grooves I3f formed by the respective flanges 13a and 13a of the bobbins 12a and 12b. Further, one of the L-shaped terminals of the L-shaped terminal 32 is inserted into the terminal holes 14b of the two total four terminal groove portions 13k formed in the wing portions 13b and 13b of the bobbins 12a and 12b. In the state in which the terminals 31 and 32 are inserted into the terminal holes 14a and 14b, the terminals 31 and 32 are formed to protrude toward the other end side of the wing portions 13a and 13b and the mounting surface side. Next, the primary winding and the secondary winding are wound around the respective primary side winding portions 1 2j and the secondary side winding portions 12k of the bobbins 12a and 1 2b. The winding of the primary windings to the bobbins 12a and 12b is such that one end is bundled on one of the four terminals 31 inserted into each of the bobbins 12a and 12b. The other end is passed through the guide groove 1. 3h, the groove portion 1 2i is guided to the primary side winding portion 12j. Then, the primary winding is wound around the primary side winding portion 12j, the other end is led to the terminal 31 through the groove portion 12j and the guide groove I3h, and the end is bundled on one of the remaining three terminals 31. As described above, the primary winding will be wound around the bobbins 1 2 a, 1 2 b. The winding of the secondary windings to the bobbins 12a and 1bb is one in which the ends of the secondary windings are inserted into the two terminals 各 of the respective bobbins 彳2a and 彳2b, and the secondary windings are passed through the grooves 13u. The tapered portion 13v is led to the secondary side winding portion 12k. Then, the secondary winding is wound on the divided area closest to the other end side of the secondary side winding portion 12k. Then, the secondary winding wound on the divided area closest to the other _= side is passed through the groove 彳2u, thereby moving to the divided area adjacent to the divided area, and the secondary winding is wound on the adjacent divided area . In this way, in the respective divided regions, the other end is led to the other end of the terminal 32 via the one end side missing portion 13q at the end closest to the split collar and the other end side 17 1308350, and because it is in phase, Reverse the phase, winding the secondary winding in turn. Then, after the portion on one end side of the field is wound, the mouth portion 12w, the notch portion 12v, the notch and the other side of the terminal 32 are so 'this is for the winding of the secondary winding to start winding and ending the volume When the winding is reversed, the end of the other end of the terminal 32 is drawn from the notch portion 1 3q to the secondary side winding portion 2k, and the secondary side is fine. The current group is sequentially wound in the divided region from the other end side to the one end side, and the other force is led to the terminal through the one end side notch portion 12W, the notch portion 12ν, and the groove portion 13u to the terminal. One of the 32's. Next, the intermediate skeleton „the skeleton 16 is disposed by the coil skeleton 12aV12b around which the primary winding and the secondary winding are wound, and the respective flanges formed on the wing portions 13b of the bobbin 12a, 2b are embedded in the intermediate bobbin 1 The longitudinal notch portion 卟 formed on the both side surfaces of the wing portion 18 is formed by fixing the bobbins 12a and 12b to the intermediate bobbin skeleton to form the bobbin body 35. After the coil bobbin body 35 is formed, The core leg portions 24f, 24h, and 24g of the magnetic core 24a constituting the core member 24 are respectively inserted into the hole 12d of the bobbin 12a, the hole 17a of the intermediate bobbin skeleton, and the hole 12d of the bobbin 12b, and also magnetically: The magnetic core leg portions 24f, 24h, 24g of the 3⁄4 24b are inserted into the hole 12d of the bobbin 12a, the intermediate bobbin, the hole 7a of the bobbin 12b, and the hole 12d of the bobbin 1 2b, and then the core 2 4 a and the core 2 4 b is butted from both sides of the coil bobbin 35. Then, the end core portions 24d, 24e of the magnetic cores 24a, 24b and the 18 1308350 of the core legs 24f, 24h, 24g are as described above. The end face of the inverter transformer was manufactured with a primer fixed at 10. In the inverter transformer configured as described above, the core member 24 forms a closed magnetic circuit that connects the respective bobbins 彳 2a, 彳 2b, 16 constituting the coil bobbin 35. Therefore, it is generated by the primary winding and the secondary winding. The magnetic flux forms a magnetic circuit in the closed magnetic circuit. Therefore, it is possible to prevent the magnetic flux from leaking from the inversion phase to the outside, thereby preventing the liquid crystal display having the inverted phase change pressure. ϋ胄There is noise and eddy current in various electrical equipment. Also, 'in the inverter transformer! 〇, because the intermediate bobbin, 6 is arranged around the magnetic foot legs 24h, 24h', so even if the magnetic core is docked In the case of a leakage type inverting transformer in which a gap is formed between the portions 24h and 24h, the magnetic flux leaking from the gap can be closed by the intermediate bobbin 16. Further, in the inverter transformer 10, the bobbin 12a and the coffee are used. On the stage side winding portion 12k, the winding flange portions 12n, 12s are arranged to be aligned along the longitudinal direction of the bobbins 12a, 12b. Therefore, the secondary winding can be wound by sequentially winding the secondary windings in the divided region. From the line The other end of the f-frame 12 is wound side-to-end side. Therefore, it is not necessary to make the secondary winding reciprocally wound on the bobbin, so that the potential difference can be prevented from riding at the end of the winding winding and the material I group. At the end (four) touch. In this case, the insulation is broken between the ends of the group and the end of the group. The result is that the ends can be prevented from knowing each other. --- mouth" I (on the corner of the square The notch portion 12ν as a notch is formed, and the winding flange portion formed at the position closest to the one end side of the notch portion 12ν is cut to the upper end of the other portion than the other notch '12v. In the side notch, the secondary and = ends wound on the secondary side winding portion 彳2k can be surely led to the terminal & provided at the wing portion i3b. Further, since the end-side notch portion 12w is cut at a position above the other notch portion i2v, it is not applied to the end of the secondary winding, and the end is bundled on the terminal 32. Therefore, the endfelf line of the secondary winding can be prevented. The fork, the field or the n is deep because the notch portion 12V and the one end side notch portion 12w == the edge portion 12" the left and right sides, so that the secondary winding starts winding regardless of which of the two terminals 32 on the crucible 13b become possible.

In the above embodiment, the core member 2 is provided by two magnetic core legs 24f, 24g, and 24h on the core of the Γ7 word 20 1308350. Although the core members 24a and 24b are configured, the magnetic core members 24 may be formed of a magnetic core having three core legs and a 丨-type magnetic core provided on a U-shaped magnetic core. Further, the lengths of the end core portions 24d and 24e and the core leg portions 24f, 24g, and 24h provided in the magnetic cores 24a and 24b may be different lengths. Further, in the above-described embodiment, the number of the winding flange portions 2 n and 12 s is five, but the number is not limited thereto, and the number of each may be four or four or less, six or six. the above. Further, in the above-described embodiment, the tubular portion 12c has a tubular shape having a substantially square cross section. However, the tubular portion 12c is not limited thereto, and may be a tubular body having a rectangular, circular or elliptical cross section. Further, in the above embodiment, the side of the inverter transformer 1Q that is not provided with the board is not covered by the member " The inverting transformer 10 can be completely covered by the ferrite Π:::: 4 提 by raising the height. Not installed - since. Thereby, the magnetic flux m is leaked from the inverter transformer 1 to the outside more reliably.
