The present invention relates to EER and EI yarns for transformers used in various electric machines and electronic circuit devices.

And a high-frequency slit transformer composed of a coil field wound on a bobbin. In particular, the present invention provides a transformer in which a plurality of slits are formed at right angles to a central axis of a cylindrical wire portion formed on a bobbin of a transformer, and a primary coil and a secondary coil are wound in the slits. The present invention relates to providing a high-frequency slit transformer that automates the coil wire by reducing the manufacturing cost. Background art

A conventional high-frequency slit transformer will be described below with reference to the drawings. FIG. 1A is a perspective view of a bobbin used for a conventional transformer, and FIG. 1B is a cross-sectional view of FIG. 1A. As shown in FIGS.1A and 1B, the bobbin 1 has a fixing portion 3 for fixing the core support portion between two parallel-shaped rectangular parallelepiped stands 2a and 2b. . A lead wire connection terminal 8 of the core is provided on the lower surface of each of the tables 2a and 2b. On the upper part of the fixed part 3, a cylindrical ticket line part 6 is formed. A fixing portion 7 for fixing the support portion of the core is formed on the upper portion of the wire line portion 6, and a through hole 4 that penetrates the fixing portion 3, the fixing portion 7 and the wire line portion 6 at the same time is formed. I have.

FIGS. 2A and 2B (cross-sectional views of FIG. 1A) show a state in which a primary coil and a secondary coil are wound around a bobbin 1 having a structure as shown in FIG. 1A. As shown in FIG. 2A and FIG. 2B, a next coil 10a is wound first around the wire section 6, and a predetermined insulating tape 25a for insulation between layers is provided on the primary coil. Rolled up. Next, a secondary coil 20a is wound on the insulating tape 25a to provide a place for insulation between layers. A fixed insulating tape 25b is wound on the secondary coil. A primary coil 1 Ob is wound on the insulating tape 25b, and an insulating tape 25c is wound on the primary coil 10b. A secondary coil 20b is wound on the insulating tape 25c, and an insulating tape 25d is wound on the secondary coil 20b. In the above structure, a barrier tape 35 is wound between the primary coil and the secondary coil which are wired adjacent to the end of the wire section 6 of the bobbin in order to satisfy domestic and international insulation standards. The wired primary coil and secondary coil are connected to predetermined connection terminals 8 formed on the lower surfaces of the pedestals 2a and 2b. After the coil is wound on the bobbin 1 as shown in FIGS. 2A and 2B, an EER-shaped core like the structure in FIG. 3, that is, the protruding portions 3 2 protruding vertically at both ends of the support portion 29 Prepare two EER-type cores 30 each having a, 32 and a projection 31 protruding in the same direction as the projections 32a, 32b at the center of the support 29. A conventional high-frequency slit transformer is formed by sandwiching the through holes of the bobbin 1 from both directions and fixing them so that the tips of the protruding portions 32a and 32b of the two cores 30 come into contact with each other as shown in FIG.

However, in the conventional high-frequency slit transformer configured as described above, the primary coil and the secondary coil are wired in a direction perpendicular to the center axis of the cylindrical wire section 6 as shown in FIG. Therefore, in order to satisfy the specified insulation standard of the transformer, in the process of winding the primary coil and the secondary coil, be sure to wind the insulating tape on the boundary area between the primary coil and the secondary coil, and At both ends where the secondary coil and the secondary coil are wound, it is necessary to wrap a barrier tape with a predetermined distance between the primary and secondary coils. That is, a step of winding an insulating tape and a barrier tape after winding a primary coil on a bobbin, and then winding a secondary coil on the insulating tape is performed. Therefore, it is not possible to automate the wire winding process because the wire winding process of the insulating tape and the coil must be performed manually one by one.

In addition, since an insulating tape is wound on each coil layer during the varnish impregnation process to prevent short-circuiting of the coiled wire, a vacuum device is required separately to allow the varnish to penetrate all the coil layers. Is done. Disclosure of the invention The present invention has been made to solve the above problems, and has as its object to automate the coil wire.

Another object of the present invention is to provide a high-frequency slit transformer that automates the coil wire of a coil and eliminates an insulating tape or the like interposed between the coiled wires to reduce the manufacturing cost. I do.

Another object of the present invention is to perform varnish impregnation for preventing a short circuit of a coil wired at normal atmospheric pressure without a vacuum device.

To achieve the objects of the invention, the geometry of the conventional bobbin is modified, in particular in order to automate the winding of the coil.

As shown in FIGS. 5A and 5B, the bobbin 101 of the present invention is provided with a fixing portion 103 for fixing a core supporting portion between the parallelly configured bases 102a and 102b. A plurality of connection terminals 108 are provided on the lower surface of b. A cylindrical wire section 106 is provided above the fixing section 103, and a fixing section 107 for fixing a supporting portion of the core is provided above the wire section 106. Further, a through-hole 104 is provided which penetrates through the lower fixing portion 103, the cylindrical ticket line portion 106, and the upper fixing portion 107 at the same time. In particular, the cylindrical wire portion 106 is provided with a plurality of slits 150 having a predetermined interval so as to be perpendicular to the center axis of the through hole 104 formed in the cylindrical wire portion 106.

The partition wall 151 formed between the slits 150 in the bobbin structure of the present invention is made of an insulator, and the thickness of the partition wall 151 is determined in consideration of various international standards, characteristics, efficiency, and the like. Should. Similarly, the height of the partition wall 151 of the slit is determined by setting the coil height on the final surface of the coiled coil and the coil drawn out to each connection terminal of the transformer after the coil is wired on each slit. The distance should be set so that an appropriate space distance can be maintained depending on the distance from the lead wire.

On the other hand, in the high-frequency slit transformer of the present invention using the flyback method, the core 130 is provided in an ERR type or the like as shown in FIG. Projecting portions 132a and 132b are erected at a predetermined length. At the center of the support portion 129, a protrusion 131 standing in the same direction as the protrusions 132a and 132b is fixed. The length of the protrusion 131 is smaller than the length of the protrusions 132a and 132b, the two cores are arranged symmetrically, and the protrusions 132a and 132b are fixed respectively. The protruding portions 131 are formed such that the ends of the protruding portions 131 do not abut each other and have a certain interval. In addition, as shown in Fig. 7 showing a cross section of a flyback type high frequency slit lance, the primary coil is perpendicular to the central axis of the projection 131 with respect to the window area where the projection 131 of the core is formed. The secondary coil is wired and the primary coil and the secondary coil are arranged in the selected slits in a direction parallel to the central axis of the protrusion 131. The leakage inductance may be relatively higher than in conventional wire structures due to the linkage of the magnetic field between the coiled wires. Therefore, in order to maintain the coupling coefficient between the primary coil and the secondary coil at an appropriate level, the coils should be divided and arranged according to the prescribed rules.

In addition, it should be arranged so that the loss of the linkage flux between the primary coil and the secondary coil is reduced by appropriate distribution of the divided primary coil and secondary coil.

In a high-frequency slit transformer using not the flyback method but a forked method, it is not necessary to form the core with a structure as shown in FIG. A core having a shape or the like is used.

The lead wire of the primary coil and the secondary coil is connected to the selected connection terminal 108 of the bobbin alternately in both of the slits 150 on both sides based on the gap formed by 131.

The symbol “¾_Nf” shown in FIG. 7 is a feedback coil.

With reference to FIGS. 5A, 5B and 10, a forked high-frequency slit transformer according to another structure of the present invention is configured such that the bobbin 101 includes a wire portion 106 and the wire portion 106. Fixing portions 103 and 107 respectively provided at both ends of the fixing member 103, a through hole 104 penetrating the bill wire portion 106 and the fixing string portions 103 and 107, and a plurality of connection terminals 108 provided in the fixing portion 103. The core 400 includes protrusions 232 a and 232 b at both ends of the first support 229 in the same direction, and a protrusion 231 at the center of the first support 229 and the protrusion 232 a. , 232b, and the second support 230, which is in contact with the protrusions 231, 232a, and 232b, and the primary wire P1, P2 ' · Ρη, Ρ-1, Ρ-2 '· · 高周波-π and secondary coil Sl, S2---Sn. S-1, S- 2--' High frequency slit transformer with S-π Oite,

A plurality of slits 150 are provided in the bill portion 106 of the bobbin 101, and a first support portion 229 and a second support portion 230 of the core 400 are fixed to fixing portions 103, 107 at both ends of the bobbin 101, respectively. The protruding portion 231 of the core 400 penetrates through the through hole 104 of the bobbin 0 and contacts and is fixed to the central portion of the second support portion 230. The protruding portions 232a and 232b of the core are The outer side of the wire portion 106 is in contact with and fixed to both end portions of the second support portion 230,

The primary coil and the secondary coil that are wired to the wire section 106 are alternately wired to the respective slits 150 such that the primary coil and the secondary coil are symmetrical about the central section with respect to the wire section 106. The lead wires of the secondary coil and the secondary coil are connected to the selected connection terminal 108 of the bobbin 101.

The wire method and operation of the high-frequency slit transformer of the present invention will be described in detail below.

As shown in FIG. 5A and FIG. 5B, the space between the bases 102a and 102b arranged substantially in parallel is A fixing portion 103 for fixing the supporting portion of the carrier is provided, a plurality of connection terminals 108 are provided on the lower surface of the bases 102a and 102b, and a cylindrical wire portion 106 is provided on the upper portion of the fixing portion 103. A fixing portion 107 for fixing a supporting portion of a core is provided on the upper portion of the wire portion 106; a plurality of slits 150 having a predetermined interval are provided in the wire portion 106; A bobbin 101 is composed of a lower fixing portion 103, a cylindrical ticket line portion 106, and a through hole 104 penetrating the upper fixing portion 107 simultaneously.

The other parts of the bobbin 101 except for the connection terminal 108 are molded and injected integrally using an insulating plastic material. In particular, the thickness and height of the partition wall 151 between the slits 150 provided in the wire section 106 are determined in consideration of various international standards, efficiency, and the like of the transformer.

A primary coil and a secondary coil are alternately wired in each slit 150 in the bobbin wire section 106 area, and then, as an example, EER type cores 200 and 300 are inserted and mounted on the bobbin and fixed. Then, it is configured as shown in FIG. The core is not limited to the EER type, and an EE type core or the like having a structure as shown in FIG. 12 can be used. When the EE type core or the like is used, the structure of the ticket wire portion of the bobbin is shown in FIG. It is desirable that it be formed in the form of

In the bobbin 101 like the structure of FIG. 13, the coil wire portion 106 and the through hole 104 of the coil are not cylindrical but have a rectangular pattern. Therefore, the shape of the through hole and the wire section can be changed depending on the form of the core.

As shown in FIG. 7, the ends of the protrusions 131 of the upper and lower cores are not in contact with each other at the center of the through hole 104 of the bobbin, and a predetermined gap is formed. The primary coil and the secondary coil are alternately wired in each of the slits 150 formed on the bobbin wire section, and one slit is formed based on the gap formed between the protrusions 131 of the core. The primary coil is wired in both slits adjacent to the slit, and the secondary coil is placed in the next slit adjacent to the slit where the primary coil is wired. The coils are wired in the manner that they are wired. In other words, the primary coils P1 and P-1 are respectively wired in both slits based on the gap formed by the protrusions 131 of the upper core 300 and the lower core 200, and the outer coil of the primary coil P1 has two coils. The secondary coil S-1 is wired, and the secondary coil S-1 is placed in the slit outside the primary coil P-1. The primary coil P2 is wired in the outer slit of the secondary coil SI, the primary coil P-2 is wired in the outer slit of the secondary coil S-1, and the primary coil P2 is wired. The secondary coil S2 is wired to the outer slit, and the secondary coil S-2 is wired to the outer slit of the primary coil P-2.

A minimum of 4 or 5 slits are formed to increase the thickness of the partition wall of the slit in the central part, and the partition wall is used as a boundary, or one slit in the central part is used as a boundary and both are used. The high-frequency slit transformer of the present invention can be constructed by connecting the primary coil to the outside of the secondary coil, and the number of the slits 150 is increased as much as possible. The number of times the coil is divided and wound by the wire method further improves the performance of the transformer. However, when the size of the wire section is limited, the number of the slits is also limited. Therefore, it is desirable to determine the number of the slits in consideration of the size and characteristics of the transformer. In Fig. 7 and Fig. 10, nine slits are configured.)

Since the primary coil and the secondary coil are arranged in a direction parallel to the central axis of the protruding portion 131, each of the primary coil and the secondary coil is different from the conventional coil structure. In some cases, the leakage inductance is relatively high at the boundary of the projection or at the gap of the projection 131. Therefore, in order to maintain the coupling coefficient between the primary coil and the secondary coil at an appropriate level, the thickness of the partition wall 151, the width of the slit where the coil in the central part is not wired, and the gap formed by the core protrusion 131 are formed. Etc. should be properly arranged.

In particular, the number of lines of P1 and the number of lines of P-1 are the same, the number of lines of P2 and the number of lines of P-2 are the same, and the number of lines of S1 and S- It is preferable that the number of lines of 1 is the same, and that the number of lines of S2 and the number of lines of S-2 be the same. It is desirable to reduce the loss in the interlinkage magnetic flux between the coils by laying wires at a ratio of 1.3: 1 or more.

In addition, the height of the partition 151 of the slit 150 is determined by determining the height of the wire on the last surface of the coil and the coil to be drawn out to each connection terminal of the transformer after the wire is wound on each slit. Set so that an appropriate spatial distance can be maintained in consideration of the distance. As shown in FIG. 7, when the switching device having the feedback coil Nf is attached, the primary coil and the secondary coil are alternately wired in the central axis direction of the cylindrical wire portion. Therefore, if the feedback coil Nf is arranged symmetrically with respect to the center axis of the wire section or is arranged in parallel, the switching device will be stable due to geometrical magnetic field mismatch. Not done.

Therefore, in order to maintain the stability of the switching device, the feedback coil is one of the primary coil P2 or P-2, which is the outermost wire of the primary coil. It is desirable to be connected to the line. The reason why the feedback coil is wired on the wire portion of the primary coil as described above is to maintain an insulation state between the feedback coil and the secondary coil. In FIG. 7, the feedback coil Nf is wired in the primary coil wire section of P-2 for the above reason. Also, as another form of the feedback coil Nf, the number of slits is small, or it is difficult to secure the distance from the core gap, so that the feedback coil is wired on the secondary coil. Sometimes. When a feedback coil is wired on the secondary coil, it is necessary to cut off the secondary coil and the feedback coil so that they are sufficiently insulated. Therefore, a feedback coil covered with a triple insulating film It is desirable to use Also in the above case, it is desirable that the feedback coil be wired on the secondary coil wire part as far as possible from the core gap.

FIG. 8A is a diagram in which FIG. 7 is configured by an equivalent circuit. FIG. 8 shows a switching device including a footback coil Nf, a switch 415, a control circuit 410, and the like. The feedback coil Nf of the switching device is connected to a high-frequency slit transformer 500. Np is a wire of the primary coil, Ns is a wire of the secondary coil, 416 is a commutator for rectifying the output voltage, and 417 is a capacitance for flat use. The wire Np of the primary coil and the wire Ns of the secondary coil can be wired as shown in Fig. 9. In other words, the primary coils P1 and P-1 are respectively wired in both slits based on the gap formed by the protrusion 131 of the upper core 300 and the lower core 200, and the secondary coil is disposed in the outer slit of the primary coil P1. S1 is wired and the secondary coil S-1 is wired in the outer slit of the primary coil P-1 and the primary coil is inserted in the outer slit of the secondary coil S1. P2 is a ticket line and a secondary coil! The secondary coil P-2 is wired on the outer slit of the secondary coil, the secondary coil S2 is wired on the outer slit of the primary coil P2, and the secondary coil S is placed on the outer slit of the primary coil P2. -2 is a circuit equivalent to a structure with a wire.

The primary coil and the secondary coil are connected to a selected connection terminal 108 of the bobbin. In particular, the primary coil is connected to the input connection terminal, and the secondary coil is connected to the output connection terminal. The wiring connection between the primary coil and the secondary coil can be connected in various ways depending on the characteristics of the transformer. As an example, the primary coils P1 and P-1 are connected in parallel, P2 and P-2 are connected in parallel, and the secondary coils S1 and S-1 are connected in parallel, S2 and S-2 are connected in parallel, and the primary coils Pl and P-1 connected in parallel are connected in series with the primary coils P2 and P-2 connected in parallel and the secondary is connected in parallel The connection terminal 108 is connected using a lead wire so as to be connected in series with the secondary coils S2 and S-2 in which the coils Sl and S-1 are connected in parallel.

The high-frequency slit transformer of the basic flyback type configured as described above has an external structure as shown in Fig. 11, and the most distinguishing point from the conventional high-frequency slit transformer is the bobbin. Is divided into a number of slits, and a primary coil and a secondary coil are alternately arranged in the slit along the central axis of the bobbin.

As shown in Fig. 8A, the basic structure of a flyback type high frequency slit transformer has a secondary auxiliary coil on or below the secondary coil, and the secondary auxiliary coil is used as an auxiliary output power supply. Can also be used. The structure of the high-frequency slit transformer in which the secondary auxiliary coil is wired is equivalent to the circuit diagram of FIG. 8B. In the circuit diagram of FIG. 8B, Ns is a wire portion of the secondary coil and functions as a main output power, and Nsa, Nsb, Nsc ... are wire portions of the secondary auxiliary coil and functions as an auxiliary output power.

The physical wire structure of the secondary auxiliary coil will be described below using the structure of FIG. 8C as an example. As shown in FIG. 8C, the secondary coil wire lines Sl, .S2 and the primary coil wire line P2 are respectively wired in slits of the wire portion of the bobbin 101. Here, the secondary coil wire S1 + S2 constitutes the main output power, and the primary coil wire P2 constitutes the main input power. S2 ', which is wired on the secondary coil S2, is the secondary auxiliary coil. The secondary auxiliary coil S2 'serves as an auxiliary output power source like Nsa in Fig. 8B. The secondary auxiliary coil S2 ′ can be wired before the secondary coil S2 is wired, and can also be wired to the secondary coil S 1. That is, the secondary auxiliary coil S2 'Is

In the area of the slit where the secondary coils S l and S2 are wired, one or more wires can be wired by the function of a high frequency slit transformer and used as an auxiliary output power supply.

The high-frequency slit transformer of the present invention maintains at least the characteristics of the conventional high-frequency slit transformer or has better characteristics even if the coil is wired so as to have the above-described structure. Therefore, due to the structural change of the high-frequency slit transformer of the present invention, the coil lamination process, which cannot be performed in the conventional structure, can be automated, and the insulating tape or the barrier tape is separately provided. Since there is no need to do this, the unit price of products can be reduced by more than 30% compared to the past. Unlike the flyback type high frequency slit transformer, the forward type high frequency slit transformer has a structure as shown in FIG. The difference between the structure of the flyback method and the structure of the forward method is that, as shown in FIGS. 7 and 10, the protruding portion 231 of the core inserted and mounted in the through-hole 104 is not cut off inside the through-hole 104; That is being done. The winding process and assembly process of the coil of the forward type high frequency slit transformer are almost the same as those of the flyback type. Industrial applicability

The high-frequency slit transformer according to the present invention is provided with a plurality of slits 150 having a predetermined interval in the wire line portion 106 of the bobbin, as shown in FIGS. 5A and 5B, and is provided in each of the slits. By alternately laminating the 1 ^ coil and the secondary coil, the insulating tape or barrier tape can be eliminated, and the coil lamination process can be automated.

Further, in the conventional high-frequency slit transformer, after the coil is wired, a varnish impregnation step in a vacuum device is required to prevent the coil from being short-circuited. Therefore, the impregnation process can be performed at normal atmospheric pressure without a vacuum device.

Therefore, the present invention can dramatically reduce the unit price of a product by automating the coil winding process of the coil and eliminating insulating tapes and the like used in the wire section, thereby achieving a stable product. Can be produced and supplied. BRIEF DESCRIPTION OF THE FIGURES
