Description

Technical Field

[0001] The utility model relates to a winding frame, and in particular to a multi-directional winding frame. Background Art

[0002] Transformers are an essential component in electronic products. Their primary function is to convert the driving voltage within electronic circuits. For example, transformers in electronic devices can step up or down the operating voltage, or they can step down the mains voltage. Therefore, transformers come in a wide variety of specifications, with few fixed ones. Most transformers are custom-made to meet customer needs.

[0003] To meet customer needs, transformers require different winding frames. After the required number of turns is achieved, the wire exits the winding slot and connects to the baseboard along the winding direction. Therefore, winding frames can be simply categorized as vertical or horizontal, based on their orientation relative to the baseboard. However, even for winding frames with similar configurations, different winding frame orientations require different developments. This means that at least two production molds must be produced for each configuration, resulting in high costs. Utility Model Content

[0004] The utility model relates to a multi-directional winding frame and electronic equipment using the same, which can save the cost of mold development.

[0005] According to one aspect of the present invention, a multi-directional winding frame is proposed, comprising a main body, a winding trough, and a wire outlet trough structure. The main body is provided with a first wall structure, a second wall structure, and a through hole, wherein the first wall structure and the second wall structure are located at both ends of the main body in a first direction, and the through hole passes through the center of the main body, the first wall structure, and the second wall structure in the first direction. The winding trough is located between the first wall structure and the second wall structure, and the winding trough is arranged around the circumference of the main body. The wire outlet trough structure is arranged on the second wall structure, and the wire outlet trough structure has at least one first wire outlet trough and at least one second wire outlet trough, and the wire outlet direction of the first wire outlet trough is different from the wire outlet direction of the second wire outlet trough.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0036] Figure 1A and Figure 1B Schematic diagrams of an electronic device 100 with a multi-directional winding frame 120 and a magnetic core 110 thereof according to an embodiment of the present invention are respectively shown. Figure 2A and Figure 2B Schematic diagrams of an electronic device 100 and its magnetic core 110, each with a multi-directional bobbin 120, according to another embodiment of the present invention are shown. The electronic device 100 may be, for example, a transformer, such as one that steps up or down an operating voltage, or a power transformer that steps down a mains voltage. Furthermore, the electronic device 100 may also be an inductor used in a power supply. The electronic devices 100 of the two aforementioned embodiments share the same bobbin, saving mold development costs.

[0037] The electronic device 100 includes a magnetic core 110, a winding group 116, and a multi-directional winding frame 120. The magnetic core 110 has an outer ring portion 112 and a center column 114 disposed inside the outer ring portion 112. The outer ring portion 112 is disposed around the center column 114, and the axial direction of the center column 114 is substantially parallel or perpendicular to the direction of the winding group 116. This configuration in which the axial direction (Z-axis direction) of the center column 114 is parallel to the direction of the winding group 116 (Z-axis direction) can be called a vertical magnetic core 110, such as Figure 1A and Figure 1B Another configuration in which the axial direction (Z-axis direction) of the center column 114 is perpendicular to the outgoing direction (Y-axis direction) of the winding group 116 can be called a horizontal magnetic core 110, as shown. Figure 2A and Figure 2B shown.

[0038] The winding set 116 can be a set of coils or multiple sets of coils, which are wound on a multi-directional winding frame 120, such as Figure 1A and Figure 2AAs shown. The coil of the winding group 116 can extend from at least two outlet portions 118 at both ends of the multi-directional winding frame 120. The extension direction of the two ends of the coil away from the winding frame 120 after the last approach is the outlet direction, but the two outlet portions 118 are not limited, and the winding group 116 can be electrically connected to the external circuit board 102 through the outlet portion 118 to transmit current. The outlet direction of the winding group 116 can be adjusted according to demand. For example, the outlet direction of the winding group 116 can be changed to match the multi-directional winding frame 120 used in this embodiment. There is no need to develop a new mold, so as to reduce the development cost of the mold. The outlet directions of the two winding groups 116 are explained below.

[0039] Please refer to Figures 1A to 1C The multi-directional winding frame 120 includes a main body 121, a winding groove 125, and a wire outlet groove structure 126. The multi-directional winding frame 120 can be an integrally formed structure, and the main body 121 of the multi-directional winding frame 120 can be mounted in the center of the outer ring portion 112 of the magnetic core 110, so that the center column 114 can be inserted into the main body 121 of the multi-directional winding frame 120. The wire outlet groove structure 126 can be arranged outside the outer ring portion 112 to facilitate the winding group 116 to extend from the two ends of the outer ring portion 112 to form two wire outlet portions 118 and adjust the wire outlet direction.

[0040] like Figure 1C As shown, the body 121 is provided with a first wall structure 122, a second wall structure 123, and a through hole 124 extending through the center of the body 121. The first wall structure 122 and the second wall structure 123 are located at opposite ends of the body 121 in a first direction (e.g., the Z-axis direction). The through hole 124 extends through the center of the body 121, the first wall structure 122, and the second wall structure 123 in the first direction (e.g., the Z-axis direction).

[0041] In addition, the winding groove 125 is disposed around the circumference of the body 121 and is located between the first wall structure 122 and the second wall structure 123 , so that the winding assembly 116 can be wound around the winding groove 125 .

[0042] In addition, the wire outlet trough structure 126 is provided on the second wall structure 123. The wire outlet trough structure 126 has a first wire outlet trough 127 and a second wire outlet trough 128. The wire outlet direction of the first wire outlet trough 127 is different from the wire outlet direction of the second wire outlet trough 128. The first wire outlet trough 127 or the second wire outlet trough 128 can be provided separately or in pairs. The following description takes the provision of a pair (two) of first wire outlet troughs 127 or a pair (two) of second wire outlet troughs 128 as an example, but the actual number is not limited. Figure 1C and Figure 2CAs shown, the two first outlet grooves 127 are respectively located at the two ends of the outlet groove structure 126 in the second direction (for example, the X-axis direction), or the two second outlet grooves 128 are respectively located at the two ends of the outlet groove structure 126 in the second direction (for example, the X-axis direction). The outlet direction (for example, the Z-axis direction) of the first outlet groove 127 is substantially parallel to the axial direction (for example, the Z-axis direction) of the through hole 124. In other words, the outlet direction (for example, the Z-axis direction) of the first outlet groove 127 is substantially parallel to the axial direction of the central column 114 of the magnetic core 110 (see Figure 1B and Figure 2B ). In addition, the wire outlet direction (e.g., Y-axis direction) of the second wire outlet slot 128 is substantially perpendicular to the axial direction (e.g., Z-axis direction) of the through hole 124. In other words, the wire outlet direction (e.g., Y-axis direction) of the second wire outlet slot 128 is substantially perpendicular to the axial direction of the central column 114 of the magnetic core 110 (see Figure 1B and Figure 2B ).

[0043] In one embodiment, the center column 114 of the magnetic core 110 can be inserted into the through hole 124 of the multi-directional winding frame 120, and the winding group 116 extends from the two ends of the multi-directional winding frame 120 in the second direction (e.g., the X-axis direction) to form two outlet portions 118, and can be selectively extended from the first outlet slot 127 or the second outlet slot 128 located at the two ends of the second direction (e.g., the X-axis direction). Figure 1A As shown, when the winding group 116 is discharged from the first outlet slot 127, the outlet direction (Z-axis direction) of the winding group 116 is substantially parallel to the axial direction (Z-axis direction) of the central column 114 of the magnetic core 110. Figure 2A As shown, when the winding set 116 is discharged from the second outlet slot 128 , the outlet direction (Y-axis direction) of the winding set 116 is substantially perpendicular to the axial direction (Z-axis direction) of the central column 114 of the magnetic core 110 .

[0044] Please refer to Figure 3A In one embodiment, the first outlet groove 127 and the second outlet groove 128 can be two outlet grooves that intersect vertically. The outlet direction of the first outlet groove 127 and the outlet direction of the second outlet groove 128 have an intersection point C1 to form a cross-shaped structure. The cross-shaped structure can facilitate the winding group 116 (not shown) to enter from any direction of the cross-shaped structure (for example, direction A1) and then exit from one of the other three directions (for example, direction A2, A3 or A4). Please refer to Figure 3BIn another embodiment, the first outlet slot 127 and the second outlet slot 128 may be two perpendicularly intersecting outlet slots, with the outlet directions of the first outlet slot 127 and the second outlet slot 128 intersecting at a point C2, thereby forming a T-shaped structure. The T-shaped structure facilitates the winding assembly 116 (not shown) to enter from any orientation of the T-shaped structure (e.g., orientation A1) and exit from one of the other two orientations (e.g., orientations A2 or A3).

[0045] This embodiment does not limit the shape of the first outlet groove 127 and the second outlet groove 128. Figure 3C The first outlet groove 127 and the second outlet groove 128 can also be two independently arranged outlet grooves, and the outlet direction of the first outlet groove 127 and the outlet direction of the second outlet groove 128 have no intersection. For example, the first outlet groove 127 is I-shaped, and the second outlet groove 128 is L-shaped. In this way, the outlet direction of the first outlet groove 127 (for example, direction A3) and the outlet direction of the second outlet groove 128 (for example, direction A2) can be different, and vice versa. In addition, please refer to Figure 3D The first wire outlet groove 127 and the second wire outlet groove 128 can also be two wire outlet grooves with a cross structure or two wire outlet grooves with a T-shaped structure (not shown). In this way, the winding group 116 (not shown) can enter from any direction of the cross structure or the T-shaped structure (for example, direction A1) and then exit from another direction (for example, direction A2 or A3). In this way, the wire outlet direction of the first wire outlet groove 127 can be different from the wire outlet direction of the second wire outlet groove 128.

[0046] In summary, although the present invention has been disclosed above with reference to the embodiments, these are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended patent claims.
