New description: [New technical field] The present invention relates to a transformer core member, in particular to a transformer core member that effectively utilizes the projected area of the transformer. [Prior Art] _ The conventional transformer is a combination of a core and a coil. In the center of the iron core, the center column is disposed on both sides of the center column, and two side walls extending in parallel and parallel with the center stomach column are disposed at equal intervals, and magnetically connected magnetic conductive portions are respectively disposed at the two ends of the center column and each side wall. A two-hole portion is formed between the center pillar, the two side walls, and the two magnetic conductive portions. Considering the efficiency of the magnetic flux flow during electromagnetic induction, the central cylindrical surface area perpendicular to the direction in which the center column extends is slightly equal to the sum of the two side wall surface areas perpendicular to the extending direction of the two side walls, and the central cylindrical surface area is slightly equal to two The sum of the cross-sectional areas of the two magnetic conductive portions perpendicular to the direction in which the magnetic conductive portion extends is preferable. The coil is wound around the center through the hole. Column. When making a transformer with such a core-wound coil, in order to reduce the magnetic resistance caused by the air enthalpy, the gap between the coil and the iron core is preferably as small as possible, that is, when designing the transformer, it is necessary to consider that the coil must fill the hole as much as possible. space. Therefore, the wire must be wound through the space of the limited hole portion, which is very inconvenient to manufacture. In order to facilitate the fabrication of the transformer, conventional techniques generally decompose an iron core into two core members so that the hole portion becomes a groove portion that is open on one side. And the coil is pre-rolled in a predetermined specification. After the coil is sleeved into the groove portion of the core member, the other core member is magnetically coupled to the core member that has been inserted into the coil, and then the two cores are fixed by fixing means 3 such as an adhesive, a casing, a screw, and a nail rivet. The member, which is drawn from the coil but in the above transformer, is located at the part and is made into a transformer. The coils outside the pole ice, the raw shovel, and the hole 4 are all leaked from the iron shovel. In this regard, the conventional technology sets the side wall with a ==='〒 shape, and the center column and the other side of the Qiu and Tianda Park I form a transformer coil: two == the wall thickness is slightly equal, so the groove The groove width of the portion is preferably equal. When the pre-performance is smeared, the coil system of the _a 圏a set of the core member is located in the c-shaped side wall, and the iron core of the cover can improve the leakage flux, but Since the magnetic connection 2 and the side (four) magnetic guides are connected to each other (the outer edge of the zigzag side wall, when the line == bow out of the outside), the tap must be placed outside the core. The configuration of 2 occupies the space of the circuit board, which does not meet the current small and compact requirements for various electronic devices. [New content] The element is L solution. The above problem is provided by the 'new type of transformer core' - the central column, and the side walls of the §-匚-shaped side are equally spaced on both sides of the middle tonnage The U-shaped opening is opposite to the column, and the stem is extended to the same side, and the two sidewalls are not connected to each other and the two sidewalls are formed with a 'drain 11 coil moment=slot portion'. The center pillar and the two sidewalls A magnetically coupled, = two magnetically conductive portion is disposed between the bottom portions, and the transformer core member includes two notches ' respectively located at opposite sides of the central portion of the central column. The central cylindrical area perpendicular to the extending direction of the 5 nautical column is slightly equal to the sum of the two side wall areas perpendicular to the extending direction of the two side walls: between the column and the two side walls: the cylindrical area of the two cores The side wall extending direction is perpendicular, and the sum of the cross-sectional areas of the magnetic conductive portion is preferable, and the center pillar is slightly equal to the transformer 11 in the transformer 11 which is perpendicular to the extending direction of the two magnetic conductive portions. The groove width of the groove portion is equal to the pressure change=core type transformer, which includes two of the above-mentioned knots; the center of the core member of the iron core member and the side wall are magnetically connected only from the notch to the second iron foot without the groove portion of the member. Coil. The tap of the coil ^^ does not extend beyond the outer edge of the side wall. Alternatively, the member is fixed by an adhesive, a casing, a wire, a wire, or the like. [Embodiment] Fig. 1 is a perspective view of a transformer core member of the present invention. Fig. 2 is a plan view of the transformer core and members of Fig. 1. As shown in the figure, a central column 1〇〇 is arranged in the center of the transformer core member, and a U-shaped side wall 2〇〇A, 200B′ is provided on both sides of the center column 100 at equal intervals. The U-shaped opening extends toward the same side of the center post 100 and the center post 100, and the two side walls 2〇〇a, 200B do not contact each other. The efficiency of the magnetic flux flow during electromagnetic induction is 丨1〇, which is perpendicular to the direction in which the center pillar 100 extends, and is slightly equal to the sum of the areas of the two side wall surfaces 210A, 210B perpendicular to the extending direction of the two side walls 200A, 200B. The rectangular groove portion 500 in which the transformer coil is disposed is formed between the center column 100 and the two side walls 200A, 200B. Since the coil wall thickness M399420 of the coil is slightly equal, the groove width of the groove portion 500 is preferably equal. A magnetically coupled magnetic conducting portion 300 is disposed between the center post 100 and the bottoms of the two side walls 200A, 200B. In addition, the transformer core member of the present invention includes two notches 400 which are respectively located on opposite sides of the bottom side walls 200A, 200B of the center column 100. Due to the arrangement of the two notches 400, the magnetic conductive portion 300 is not connected to the outer edges of the double-shaped side walls 200A, 200B, but in consideration of electromagnetic induction, the magnetic flux is arranged in a fan shape from the side walls 200A, 200B toward the center column 100, so even The magnetic conductive portion 300 is continuously disposed at the position of the notch 400, and little magnetic flux passes therethrough. However, it is considered that the efficiency of the magnetic flux flow during electromagnetic induction is the area of the central cylindrical surface 110 perpendicular to the extending direction of the central column 100, which is slightly equal to the direction perpendicular to the direction in which the two magnetic conductive portions 300 extend toward the side walls 200A, 200B, and is centered on the central column 100 and the side wall 200A. The sum of the cross-sectional areas of the two magnetic conductive portions 300 between 200B is preferable. In addition, when designing the iron core, the energy consumption loss of the iron core is considered according to the following formula. B= (ExlO8) / (4^-fxNxAe)

Frequency of current 6 M399420 If the effective core cross-sectional area (Ae) increases while other values do not change, the magnetic flux density ( B) reduction, therefore, the loss of core performance is also reduced by the transformer core member of the present invention, because the side walls 200Α, 200Β are U-shaped, if the same cross-sectional area, the U-shaped side walls 200Α, 200Β compared to The cylindrical side walls enclose the coil in a surrounding manner, and the magnetic flux of the coil is fully utilized by the side walls 200Α, 200Β, that is, the effective core wearing area (Ae) is increased, and the magnetic flux density (Β) is relatively reduced. It can be seen that the application of the transformer core member of the present invention also has the effect of reducing the iron core effect energy consumption. When the transformer is fabricated using the transformer core member of the present invention, the pre-wound coil is inserted into the groove portion 500 of the core member, and the other core member and the core member that has been fitted into the coil are assembled as in the prior art. The center pillar is magnetically coupled to the side wall, and then the two core members are fixed by fixing means such as an adhesive, a casing, a screw, and a nail rivet, and the tap of the coil is taken out to the outside. However, when the tap of the coil is drawn, the tap of the coil is only pulled downward from the notch 400 without exceeding the outer edge connection range of the side walls 200A, 200B. The position of the coil tap is fixed to complete the transformer. The transformer made of the transformer core member of the present invention is composed of two iron core members, which facilitates the assembly of the coil and the iron core, and the coil is completely located in the U-shaped sidewall, which can improve the leakage flux and reduce the iron core. The loss of performance, in addition to the configuration of the gap, the tap of the coil is only pulled out from the gap without exceeding the outer edge of the side wall, that is, it does not occupy the space outside the core, and effectively utilizes the projected area of the transformer. When such a transformer is applied to an electronic product, other components can be densely arranged on the circuit board next to the transformer 7 M399420, which meets the current demand for compactness of various electronic products. Although the embodiment of the transformer core structure of the present invention has been disclosed in the specification and drawings, it is not intended to limit the present invention, and the patent scope of the present invention is defined in accordance with the scope of the patent application.
