Description

Bobbin assembly

[0001] The present invention relates to a bobbin assembly, and more particularly, to a bobbin assembly having a structure in which the bonding between each component is easy and the bonding strength can be improved.

[0002] A converter is a device that receives direct or alternating current and converts it back into direct or alternating current. Converters can be installed and used in any type of device that requires an external power supply.

[0003] Converters can take various forms depending on the power they receive and the power they supply. For example, converters can be configured to convert various types of current, such as DC / DC converters and AC / DC converters, into a preset current form.

[0004] To achieve this, converters typically comprise a core formed from a magnetizable material and a coil wound around the core. Considering manufacturing efficiency and the potential for electrical interference, the coil is wound around a structure called a bobbin. The core is housed within the bobbin, and the coil can be wound around the bobbin housing the core.

[0005] Recently, with the increasing size of industrial facilities and equipment, the rated capacity of converters has also increased. Consequently, the cores and coils used in converters are also growing in size. Consequently, the bobbins on which the cores are housed and the coils are wound are also growing in size.

[0006] Referring to FIGS. 21 to 26, a bobbin assembly (1000) according to the prior art is illustrated. The bobbin assembly (1000) according to the prior art is configured to include a winding frame (1200) on which a coil (C) is wound and which accommodates a core member (1300), and a support frame (1100) that is coupled to and supports the winding frame (1200).

[0007] The winding frame (1200) is provided as a pair, including a first winding frame (1200a) and a second winding frame (1200b). The coil (C) is wound on each of the first winding frame (1200a) and the second winding frame (1200b), and the coils (C) wound on the first winding frame (1200a) and the second winding frame (1200b) are continuous with each other.

[0008] Accordingly, as best illustrated in Fig. 22, the coil (C) wound on the first winding frame (1200a) and the second winding frame (1200b) is formed to have a cross-section in the shape of the number “8” rotated by 90°.

[0009] Therefore, when the first winding frame (1200a) and the second winding frame (1200b) are formed as a single member, the winding of the coil (C) must be performed manually by an operator. To this end, the bobbin assembly (1000) according to the prior art separately comprises the first winding frame (1200a) and the second winding frame (1200b). After the coil (C) is wound on the first winding frame (1200a) and the second winding frame (1200b), respectively, the first winding frame (1200a) and the second winding frame (1200b) can be coupled to each other.

[0010] That is, as best illustrated in Fig. 23, the first and second winding frames (1200a, 1200b) are coupled to each other (①) and then coupled to the support frame (1200) (②). Thereafter, one of the pair of core members (1300) is moved from the upper side to the lower side and coupled to the first and second winding frames (1200a, 1200b), and the other is moved from the lower side to the upper side and coupled to the support frame (1100).

[0011] At this time, the first and second winding frames (1200a, 1200b) are configured to include a winding head (1210) constituting the upper side, a winding body (1220) on which a coil (C) is wound, and a winding coupling part (1230) coupled with a support frame (1100).

[0012] The winding head (1210) is a portion where the first and second winding frames (1200a, 1200b) are joined to each other. In addition, a core member (1300) is inserted into the winding head (1210). As the core member (1300) is inserted, the first and second winding frames (1200a, 1200b) can be firmly joined to each other.

[0013] However, the first and second winding frames (1200a, 1200b) are connected to the support frame (1100) only by the winding coupling portion (1230). Specifically, as illustrated in FIGS. 24 to 26, the winding coupling portion (1230) is formed in the shape of a hook and is hook-connected to the support coupling portion (1110) formed in the shape of a groove.

[0014] Since the first and second winding frames (1200a, 1200b) that extend in the vertical direction are connected only by line contact through the winding joint (1230) and the support joint (1110), it is difficult to secure sufficient bonding strength.

[0015] Meanwhile, hook coupling requires a certain amount of clearance. Accordingly, the first and second winding frames (1200a, 1200b) are coupled to the support frame (1100) while ensuring a certain amount of clearance. Accordingly, there is a risk that the first and second winding frames (1200a, 1200b) may oscillate, thereby reducing the coupling strength with the support frame (1100).

[0016] Additionally, due to the nature of the hook connection, the connection is released when a force in a specific direction is applied. Therefore, as the first and second winding frames (1200a, 1200b) continue to swing, there is also a risk that the connection between the support connection part (1110) and the winding connection part (1230) may be randomly released.

[0017] Accordingly, a bobbin is required that can easily wind a coil (C) and be stably combined with other components.

[0018] Korean Patent Publication No. 10-2023-0146498 discloses an inductor and a DC converter including the same. Specifically, the inductor includes a pattern portion, which is wound along the outer circumference of a coil portion, and a plurality of metal conductors, each overlapping and wound together in the thickness direction, and extending along the winding direction, and a DC converter including the same are disclosed. The above-mentioned prior document discloses the effect of mitigating the skin effect by the pattern portion.

[0019] However, the inductor and DC converter including the same disclosed in the above-mentioned prior art document only provide a method for mitigating the skin effect. In other words, the above-mentioned prior art document does not provide a method for improving the coupling between the intermediate stage and other components while facilitating the winding of the coil portion.

[0020] Japanese Patent Publication No. 2023-139567 discloses an inductor and a DC / DC converter including the inductor. Specifically, the inductor includes a plurality of soft magnetic thin films, thereby reducing coupling between coil conductors wound around a magnetic core, and a DC / DC converter including the inductor.

[0021] However, the inductor and DC / DC / converter including the same disclosed in the above-mentioned prior art document only provide a method for eliminating electrical interference between coil conductors. The above-mentioned prior art document fails to provide a method for easily winding the coil conductor while improving the coupling between different components.

[0022] The present invention is intended to solve the above problems, and an object of the present invention is to provide a bobbin assembly having a structure that facilitates coil winding.

[0076] Referring to FIGS. 1 to 3, a bobbin assembly (10) according to an embodiment of the present invention is illustrated. The bobbin assembly (10) according to an embodiment of the present invention may be installed and utilized in any device in which a magnetic field is to be formed by an external current. In one embodiment, the bobbin assembly (10) may be installed in an inductor of a converter.

[0077] In the above embodiment, the bobbin assembly (10) can be equipped and utilized in a large-capacity converter, i.e., any device that can be formed. That is, the bobbin assembly (10) can be utilized in a converter that has a large current strength. To this end, the bobbin assembly (10) can be configured to include a coil (C) and core member (400) that are relatively larger in size than those equipped in a typical converter.

[0078] At this time, the bobbin assembly (10) according to the embodiment of the present invention is configured to easily wind, couple, and stably support the enlarged core member (400) and coil (C). Accordingly, even when the capacity of the converter equipped with the bobbin assembly (10) increases, the core member (400) and coil (C) can be easily coupled while the coupling state can be stably supported.

[0079] A coil (C) is wound on the bobbin assembly (10). As will be described later, the coil (C) is wound in a figure-of-eight shape on a winding frame (300) that accommodates a core member (400). At this time, a plurality of winding frames (300) are provided, and the plurality of winding frames (300) can be combined with other components of the bobbin assembly (10) after the coil (C) is wound on them.

[0080] Accordingly, the coil (C) winding process can be automatically performed by a machine or the like, thereby improving work efficiency.

[0081] In the illustrated embodiment, a bobbin assembly (10) according to an embodiment of the present invention may include a support frame (100), a cover frame (200), a winding frame (300), and a core member (400).

[0082] At this time, the winding frame (300) extends in one direction with a height, and the coil (C) can be wound.

[0083] And, the support frame (100) can be combined with the winding frame (300) while supporting the winding frame (300) from one side in one direction.

[0084] And, the core member (400) can be coupled while being at least partially accommodated within the interior of the winding frame (300) along one direction.

[0085] Meanwhile, the cover frame (200) can be coupled to the winding frame (300) by covering the coil (C) coupled to the winding frame (300) on one side in one direction opposite to the other side in one direction of the winding frame (300) to which the support frame (100) is coupled.

[0086] At this time, in the embodiment of the present invention, the winding frame (300) is coupled to the support frame (100) while sliding along a direction other than one direction, and at this time, the coupled portion can be coupled so as to be supported while at least partially making surface contact with the support frame (100).

[0087] Referring again to Figures 1 to 20, the following description is given in more detail.

[0088] The support frame (100) constitutes a portion of the outer shape of the bobbin assembly (10). The support frame (100) is coupled to other components of the bobbin assembly (10) to support them. The support frame (100) constitutes one side in the height direction of the bobbin assembly (10), i.e., the lower side in the illustrated embodiment. The support frame (100) supports other components of the bobbin assembly (10) from said one side, i.e., the lower side.

[0089] The support frame (100) is positioned apart from the cover frame (200). The support frame (100) is positioned apart from the cover frame (200) along the height direction of the bobbin assembly (10), i.e., the vertical direction in the illustrated embodiment. A winding frame (300) is positioned between the support frame (100) and the cover frame (200).

[0090] The support frame (100) is coupled with the winding frame (300). The support frame (100) supports the winding frame (300) from the lower side. At this time, the support frame (100) and the winding frame (300) may be coupled in a direction different from the height direction of the winding frame (300), for example, in the horizontal direction.

[0091] Accordingly, the support frame (100) and the winding frame (300) can be easily combined, while the combined state can be stably maintained. A detailed description thereof will be provided later.

[0092] The support frame (100) is coupled with the core member (400). The support frame (100) supports the second core member (400b) located on the one side, i.e., the lower side, of the pair of core members (400) in the height direction. As will be described later, the second core member (400b) is coupled to the support frame (100) while being coupled to the winding frame (300), so it can be said that the core member (400) is coupled to the support frame (100) via the winding frame (300).

[0093] In the embodiment shown in FIGS. 4 to 6, the support frame (100) includes a support body (110), a support rack (120), a winding frame receiving portion (130), and a core member receiving portion (140).

[0094] The support body (110) constitutes the outer shape of the support frame (100). The support body (110) can be combined with other components of the support frame (100) to support them. In addition, other components of the support frame (100) can be formed on the support body (110).

[0095] In the illustrated embodiment, the support body (110) is coupled to the support rack (120). In addition, a winding frame receiving portion (130) and a core member receiving portion (140) are formed inside the support body (110).

[0096] The support body (110) may be combined with other components of the support frame (100) to support them, or may have any shape that allows other components to be formed. In the illustrated embodiment, the support body (110) has a polygonal prism shape in which the length in the left-right direction is longer than the width in the front-back direction and the height in the up-down direction is greater.

[0097] The support body (110) is coupled with the support rack (120). The support body (110) can be positioned to be supported on the ground by the support rack (120). In the illustrated embodiment, one side of the support body (110) in the height direction, i.e., the lower side, is coupled with and supported by the support rack (120).

[0098] A winding frame receiving portion (130) is formed on the support body (110). The winding frame receiving portion (130) is formed on the other side in the height direction of the support body (110), in the illustrated embodiment, on the upper side.

[0099] A core member receiving portion (140) is formed inside the support body (110). The core member receiving portion (140) is formed to penetrate the horizontal inner side of the support body (110) in the height direction of the support body (110), i.e., in the up-down direction.

[0100] The support rack (120) is coupled to the support body (110) and supports it. The support body (110) can be positioned to float on the ground by the support rack (120).

[0101] A plurality of support racks (120) may be provided. The plurality of support racks (120) may be coupled to the support body (110) at different locations. In the illustrated embodiment, two pairs of support racks (120) are provided.

[0102] A pair of support legs (120) are connected to one longitudinal side of the support body (110), the lower side of the left end in the illustrated embodiment. The pair of support legs (120) are spaced apart in the width direction of the support body (110), the front-back direction in the illustrated embodiment.

[0103] Another pair of support legs (120) is connected to the other longitudinal side of the support body (110), i.e., the lower side of the right end in the illustrated embodiment. The other pair of support legs (120) are spaced apart in the width direction of the support body (110), i.e., in the front-back direction.

[0104] The winding frame receiving portion (130) is a portion where the support frame (100) is coupled to the winding frame (300). The winding frame (300) can be coupled to the winding frame receiving portion (130) and supported by the support frame (100).

[0105] The winding frame receiving portion (130) is formed in the support body (110), and one side in the other direction where the winding frame (300) is coupled to the support frame (100) is formed open, so that the winding frame (300) can be received in a withdrawable manner and the received winding frame (300) can be supported.

[0106] The winding frame receiving portion (130) is formed on one side in the height direction of the support body (110), that is, on the upper side in the illustrated embodiment. One side in the width direction of the winding frame receiving portion (130), that is, on the front side in the illustrated embodiment, is closed. The other side in the width direction of the winding frame receiving portion (130), that is, on the rear side in the illustrated embodiment, is formed at least partially open.

[0107] Accordingly, the winding frame (300) can be moved to one side in the width direction of the support body (110), i.e., the front side, and coupled with the winding frame receiving portion (130). In addition, the winding frame (300) can be moved to the other side in the width direction of the support body (110), i.e., the rear side, and separated from the winding frame receiving portion (130). In one embodiment, the winding frame (300) can be slidably coupled to or separated from the winding frame receiving portion (130).

[0108] As a specific example, referring to FIG. 11, the winding frame (300) extends in one direction, has a coil (C) wound around it, and includes a winding body (310) that at least partially accommodates a core member (400) therein.

[0109] And, the winding frame (300) is continuous with one side of the extension direction of the winding body (310) and includes a winding base (320) that is retractably received in the above-described winding frame receiving portion (130).

[0110] At this time, the winding base (320) can be slidably coupled to or separated from the winding frame receiving portion (130).

[0111] Referring again to FIGS. 4 to 6, the winding frame receiving portion (130) is located on the inside of the support body (110). Specifically, the winding frame receiving portion (130) is located on the inside along the longitudinal and width directions of the support body (110). In the illustrated embodiment, the winding frame receiving portion (130) is located on the inside of the left and right ends of the support body (110). In addition, the winding frame receiving portion (130) is located on the inside of the front end of the support body (110).

[0112] A plurality of winding frame receiving portions (130) may be provided. The plurality of winding frame receiving portions (130) may be spaced apart from each other and may be respectively coupled to and support the plurality of winding frames (300).

The moving space (133) is connected to the inlet opening (131) and the receiving space (135), respectively. The moving space (133) movably accommodates the winding base (320).

[0132] The moving space (133) extends in the width direction of the support body (110), in the front-back direction in the illustrated embodiment. One side of the moving space (133) in the extension direction, the front side in the illustrated embodiment, is formed open and communicates with the receiving space (135). The other side of the moving space (133) in the extension direction, the rear side in the illustrated embodiment, is formed open and communicates with the inlet opening (131) and the outside.

[0133] The moving space (133) is defined by being partially surrounded by the upper surface of the support body (110) and the guide cover (132).

[0138] The limiting protrusion (134) is positioned on one side in the height direction of the receiving space (135), on the upper side in the illustrated embodiment, and is arranged to cover the receiving space (135) in the height direction. The limiting protrusion (134) covers and supports one side in the length direction of the winding base (320) received in the receiving space (135), on the upper side of the front in the illustrated embodiment.

[0139] The limiting protrusion (134) extends a predetermined length in the longitudinal direction of the support body (110), i.e., in the left-right direction in the illustrated embodiment. At this time, each end of the limiting protrusion (134) in the extending direction is positioned to be spaced apart from a pair of guide covers (132). A support space (136) may be formed between each end of the limiting protrusion (134) in the extending direction and the pair of guide covers (132).

[0140] The receiving space (135) receives the winding frame (300) that is completely received in the winding frame receiving portion (130). Specifically, when the winding frame (300) continues to move along the inlet opening (131) and the moving space (133), the winding body (310) comes into contact with the limiting protrusion (134). In this state, one longitudinal side of the winding base (320) that supports the winding body (310), the front side in the illustrated embodiment, is received in the receiving space (135).

[0142] The receiving space (135) is defined by being surrounded by the support body (110), the guide cover (132), and the limiting protrusion (134). In the illustrated embodiment, one side in the height direction of the receiving space (135), i.e., the lower side, is surrounded by the upper surface of the support body (110). Each side in the width direction of the receiving space (135), i.e., the left and right sides, is surrounded by a pair of guide covers (132). The other side in the height direction of the receiving space (135), i.e., the upper side in the illustrated embodiment, is partially surrounded by the guide cover (132) and the limiting protrusion (134), respectively.

[0143] As described above, the guide cover (132) and the limiting protrusion (134) are spaced apart from each other. The receiving space (135) is connected to the support space (136) formed between the guide cover (132) and the limiting protrusion (134).

[0145] In an embodiment not shown, a fastening member (not shown) may be shown on one side of a support body (110) surrounding the receiving space (135) from the front side. The fastening member (not shown) may be detachably connected to a joining member (not shown) provided at the front end of the winding base (320).

[0146] In the above embodiment, when the winding base (320) is fully inserted into the receiving space (135), the fastening member (not shown) and the coupling member (not shown) can be coupled. In the above embodiment, the coupling strength between the support frame (100) and the winding frame (300) can be improved.

[0147] The support space (136) accommodates a guide rail (330) provided on the winding frame (300).

The upper side of the core member receiving portion (140) is in communication with the winding frame receiving portion (130) and the winding frame (300) received therein. The lower side of the core member receiving portion (140) is formed to be open and is in communication with the outside.

[0155] Accordingly, the second core member (400b) can be inserted and connected to the winding frame (300) accommodated in the winding frame accommodation portion (130) by being introduced through the lower side of the core member accommodation portion (140).

[0156] The core member receiving portion (140) may have a shape corresponding to the shape of the second core member (400b).

[0160] The cover frame (200) is connected to a plurality of winding frames (300) and supports them. In addition, the cover frame (200) supports a first core member (400a) that is connected to the plurality of winding frames (300) on one side in the height direction.

[0161] The cover frame (200) constitutes the other side of the bobbin assembly (10) in the height direction, the upper side in the illustrated embodiment. The cover frame (200) is positioned opposite the support frame (100) along the height direction of the bobbin assembly (10). The cover frame (200) is positioned facing the support frame (100) with the winding frame (300) interposed therebetween.

[0162] The cover frame (200) is coupled with a winding frame (300). That is, a plurality of winding frames (300) are provided, but the plurality of winding frames (300) are not directly coupled to each other.

[0163] Accordingly, in the bobbin assembly (10) according to an embodiment of the present invention, one side in the height direction of the winding frame (300), that is, the lower side in the illustrated embodiment, is coupled with the support frame (100), and the other side in the height direction of the winding frame (300), that is, the upper side in the illustrated embodiment, is coupled with and supported by the cover frame (200). That is, each side in the height direction of the winding frame (300) is coupled with the support frame (100) and the cover frame (200), respectively.

[0164] Accordingly, the coupling state between the winding frame (300) and other components can be stably maintained.

[0165] In the embodiments illustrated in FIGS. 7 to 9, the cover frame (200) includes a cover body (210), a cover base (220), and a winding frame coupling portion (230).

[0166] The cover body (210) constitutes the outer shape of the cover frame (200). Other configurations of the cover frame (200) may be combined or formed on the cover body (210). In the illustrated embodiment, a cover base (220) is combined on the cover body (210), and a winding frame coupling portion (230) is formed.

[0167] The cover body (210) may have a shape corresponding to the shape of the support body (110) or the direction of separation of the plurality of winding frames (300). In the illustrated embodiment, the cover body (210) is formed in a three-dimensional shape in which the length in the left-right direction is longer than the length in the front-back direction and the height in the up-down direction is greater.

[0168] A space is formed inside the cover body (210). The space is formed to have a shape corresponding to the shape of the cover body (210), i.e., a length in the left-right direction is longer than a width in the front-back direction and a height in the up-down direction. One side of the height direction of the space, in the illustrated embodiment, the upper side, is formed open so that the first core member (400a) can be inserted.

[0174] The grip groove (211) is formed recessed on the other side of the cover body (210) in the height direction, that is, on the upper end in the illustrated embodiment. The portion of the cover body (210) where the grip groove (211) is formed may be formed to have a relatively lower height than other portions. Accordingly, the first core member (400a) accommodated in the self-interest space may be exposed horizontally through the grip groove (211). The worker can easily separate the first core member (400a) by gripping the portion of the first core member (400a) exposed through the grip groove (211).

[0175] A plurality of gripping grooves (211) may be formed. The plurality of gripping grooves (211) may be formed at different locations of the cover body (210).

For this purpose, the horizontal end of the cover base (220) may be positioned outside the outer periphery of the coil (C).

[0183] In the illustrated embodiment, the cover base (220) includes a separation plate (221).

[0184] The separation plate (221) physically separates a plurality of winding frames (300) formed inside the cover body (210). The separation plate (221) is located inside the cover body (210).

[0185] In the illustrated embodiment, the spacer plate (221) is positioned at the central portion in the longitudinal direction of the cover body (210), between the first winding frame coupling portion (230a) positioned on the left and the second winding frame coupling portion (230b) positioned on the right. The spacer plate (221) supports the winding body (310) inserted into the winding frame coupling portion (230) from the inside.

[0186] The separation plate (221) may have a shape corresponding to another part of the cover base (220).

[0188] Each side in the height direction of the winding frame coupling portion (230), the upper side and the lower side in the illustrated embodiment, are formed as open. One side in the height direction of the winding frame coupling portion (230), the upper side in the illustrated embodiment, is formed as open so that the first core member (400a) can be inserted. The other side in the height direction of the winding frame coupling portion (230), the lower side in the illustrated embodiment, is formed as open so that the winding body (310) of the winding frame (300) can be inserted.

[0189] The winding frame coupling portion (230) is located inside the cover body (210) and the cover base (220). The winding frame coupling portion (230) can be defined by being surrounded by the inner periphery of the cover body (210) and the cover base (220).

[0190] In the illustrated embodiment, each side in the width direction, i.e., the front-back direction, of the winding frame coupling portion (230) is defined by being surrounded by the inner periphery of the cover body (210) and the cover base (220). The outer side in the length direction, i.e., the left or right side, of the winding frame coupling portion (230) is also defined by being surrounded by the inner periphery of the cover body (210) and the cover base (220). The inner side in the length direction, i.e., the left or right side, of the winding frame coupling portion (230) is defined by being surrounded by the spacer plate (221).

[0191] The winding frame coupling portion (230) may have a shape corresponding to the shape of the winding body (310) of the winding frame (300). In the illustrated embodiment, the winding frame coupling portion (230) is formed as a polygonal prism-shaped space having a rectangular cross-section and a vertical height.

[0192] At this time, a portion of the upper side of the winding frame joint (230) may be surrounded by the cover step (212). Accordingly, as described above, the insertion length of the winding frame (300) may be limited.

[0193] A plurality of winding frame coupling parts (230) may be formed. The plurality of winding frame coupling parts (230) may each accommodate a plurality of winding frames (300) at different locations. In the illustrated embodiment, the winding frame coupling part (230) includes a first winding frame coupling part (230a) and a second winding frame coupling part (230b).

[0194] The first winding frame coupling portion (230a) is located on one side of the cover body (210) in the longitudinal direction, i.e., on the left side, and accommodates the first winding frame (300a). The second winding frame coupling portion (230b) is located on the other side of the cover body (210) in the longitudinal direction, i.e., on the right side, and accommodates the second winding frame (300b).

[0195] A spacing plate (221) is positioned between the first winding frame coupling portion (230a) and the second winding frame coupling portion (230b). The inner sides of the first winding frame (300a) and the second winding frame (300b) accommodated in the first winding frame coupling portion (230a) and the second winding frame coupling portion (230b), respectively, can be supported by the spacing plate (221).

[0196] The winding frame (300) is configured to wind a coil (C). The winding frame (300) at least partially accommodates a core member (400). That is, the coil (C) can be wound on the winding frame (300) while the core member (400) is accommodated therein.

[0197] The winding frame (300) is coupled with the support frame (100). The winding frame (300) can be supported while coupled to the winding frame receiving portion (130). At this time, the winding frame (300) can be coupled to and separated from the support frame (100) by sliding along one side of the horizontal direction, not the height direction of the support frame (100), in the front-back direction in the illustrated embodiment.

[0198] In addition, the winding frame (300) coupled to the support frame (100) can be supported by at least partially making surface contact with the configuration of the winding frame receiving portion (130). Accordingly, the support frame (100) and the winding frame (300) can be easily coupled and separated while maintaining a stable coupling state.

[0199] The winding frame (300) is coupled with the cover frame (200). The winding frame (300) is accommodated in the winding frame coupling portion (230) formed in the cover frame (200) and can be supported by the cover body (210) and the cover base (220).

[0200] The winding frame (300) is coupled to the core member (400). The winding frame (300) can at least partially accommodate the core member (400). Accordingly, the coil (C) can achieve the effect of being wound around the core member (400).

[0201] A plurality of winding frames (300) may be provided. A plurality of winding frames (300) are respectively coupled to a plurality of winding frame receiving portions (130) and winding frame coupling portions (230), and coils (C) can be wound on each of them.

[0202] In the illustrated embodiment, the winding frame (300) is configured to include a first winding frame (300a) coupled with a first winding frame receiving portion (130a) and a first winding frame coupling portion (230a), and a second winding frame (300b) coupled with a second winding frame receiving portion (130b) and a second winding frame coupling portion (230b).

[0203] In other words, the winding frame (300) may include a first winding frame (300a) coupled to the support frame (100), and a second winding frame (300b) coupled to the support frame (100) while being physically spaced apart from the first winding frame (300a) - for example, spaced apart from each other left and right in FIG. 2. Preferably, the first winding frame (300a) and the second winding frame (300b) may have the same size and shape.

[0204] At this time, the first winding frame (300a) and the second winding frame (300b) may be configured to be physically separated from each other. That is, the first winding frame (300a) and the second winding frame (300b) may be separated from each other and after the coil (C) is wound, they may be respectively coupled to the support frame (100) and the cover frame (200).

[0205] Therefore, the coil (C) winding process can be performed automatically, so that work efficiency can be improved.

[0206] The first winding frame (300a) and the second winding frame (300b) have different positions where they are connected to the support frame (100) or the cover frame (200), but their structures and functions are identical. Accordingly, the common parts of the first winding frame (300a) and the second winding frame (300b) are collectively referred to as the winding frame (300) hereinafter.

[0207] In the embodiment shown in FIGS. 10 to 12, the winding frame (300) includes a winding body (310), a winding base (320), a guide rail (330), and a winding cavity (340).

[0208] The winding body (310) constitutes a portion of the outer shape of the winding frame (300). The winding body (310) is a portion where the winding frame (300) is coupled to the cover frame (200). In the illustrated embodiment, one side in the height direction of the winding body (310), i.e., the upper side, is accommodated in the winding frame coupling portion (230).

[0209] The winding body (310) is coupled to the winding base (320). The other side of the winding body (310) in the height direction, the lower side in the illustrated embodiment, is coupled to the winding base (320). The winding body (310) can be supported by the winding base (320).

[0210] A winding cavity (340) is formed inside the winding body (310). The inner circumference of the winding body (310) can surround the winding cavity (340) in a horizontal direction, i.e., on the front side, rear side, left side, and right side in the illustrated embodiment. The winding body (310) surrounds and supports the core member (400) accommodated in the winding cavity (340).

[0211] The winding body (310) may have a shape corresponding to the shape of the winding frame coupling portion (230) or the core member (400). In the illustrated embodiment, the winding body (310) has a polygonal prism shape with a rectangular cross-section and a vertical height.

[0212] In the illustrated embodiment, the winding body (310) includes a winding support surface (311) and a core receiving opening (312).

[0213] The winding support surface (311) supports the first core member (400a) coupled with the winding frame (300). The winding support surface (311) is defined as a portion of the outer surface of the winding body (310). In the illustrated embodiment, the winding support surface (311) is defined as the inner surface in the width direction of the winding frame (300). Specifically, the winding support surface (311) of the first winding frame (300a) is defined as the right side, and the winding support surface (311) of the second winding frame (300b) is defined as the left side.

[0214] The winding support surface (311) may be formed to have a relatively low height, i.e., a length in the vertical direction, compared to the other outer surfaces of the winding body (310). At this time, one side of the height direction of the winding support surface (311), the lower side in the illustrated embodiment, may be combined with the winding base (320) at the same position as the other outer surfaces of the winding body (310).

[0215] Accordingly, the difference in height can be formed by adjusting the height of the other side, i.e., the upper side, in the height direction of the winding support surface (311). To this end, a core receiving opening (312) is formed on the other side in the height direction of the winding support surface (311).

[0216] The core receiving opening (312) is formed recessed on the upper side of the other side in the height direction of the winding support surface (311). The core receiving opening (312) communicates with the outside along the width direction, or left and right direction in the illustrated embodiment, of the winding hollow (340).

[0217] As the core receiving opening (312) is formed, the height of the upper end of the winding support surface (311) is positioned lower than other parts. The first core member (400a) can be received in the core receiving opening (312) and supported on the upper end of the winding support surface (311).

[0218] The winding base (320) constitutes another part of the outer shape of the winding frame (300). The winding base (320) is a part where the winding frame (300) is connected to the support frame (100). The winding base (320) is accommodated in the inlet opening (131), the moving space (133), and the accommodation space (135) of the winding frame accommodation portion (130).

[0219] The winding base (320) can be supported by another configuration of the support body (110) or the winding frame receiving portion (130).

[0220] Specifically, the winding base (320) positioned in the inlet opening (131) and the moving space (133) can be supported on its lower side by the upper surface of the support body (110) and on each side in the width direction by a guide cover (132). In addition, the upper side of the winding base (320) can be supported by the guide cover (132).

[0221] In addition, the winding base (320) located in the receiving space (135) can be supported on its lower side by the upper surface of the support body (110) and on each side in the width direction by a guide cover (132). In addition, the upper side of the winding base (320) can be supported by the guide cover (132) and the limiting protrusion (134), and the front side can be supported by the front side of the support body (110).

[0222] At this time, the winding base (320) can be in surface contact with the other components of the support body (110) or the winding frame receiving portion (130). Accordingly, the coupling state of the winding base (320) and the other components can be stably maintained.

[0223] The winding base (320) is coupled to the winding body (310). The winding base (320) is coupled to the other side of the winding body (310) in the height direction, the lower side in the illustrated embodiment. The winding base (320) supports the winding body (310).

[0224] The winding base (320) is coupled with a guide rail (330). A guide rail (330) is positioned on one side of the winding base (320) in the height direction, i.e., on the upper side in the illustrated embodiment. At this time, the guide rail (330) may extend to surround the winding body (310) in the width direction, i.e., on the left or right side in the illustrated embodiment.

[0225] A winding hollow (340) extends inside the winding base (320). The winding hollow (340) penetrates the winding base (320) and its lower end is formed open. The winding base (320) can support a second core member (400b) inserted into the winding hollow (340).

[0226] The winding base (320) is coupled with the winding body (310) and the guide rail (330), and can have any shape that can be supported by being coupled with the support frame (100). In the illustrated embodiment, the winding base (320) is formed in a polygonal plate shape in which the length in the front-back direction is longer than the width in the left-right direction and the thickness in the up-down direction is greater.

[0227] In an embodiment not shown, one side of the winding base (320) that is accommodated in the accommodation space (135), in the embodiment shown, the front side may be provided with a fastening member (not shown) that is positioned inside the accommodation space (135) and a joining member (not shown) that is fastened thereto.

[0228] In the above embodiment, the winding base (320) can be additionally coupled to the support body (110) by coupling the fastening member (not shown) and the coupling member (not shown). As a result, the coupling strength of the winding frame (300) and the support frame (100) can be improved.

[0229] The guide rail (330) is supported by another configuration of the support frame (100). As the guide rail (330) is formed, the bonding strength between the winding frame (300) and the support frame (100) can be improved compared to when only the winding base (320) is provided.

[0230] Specifically, the guide rail (330) is supported in its width direction, i.e., on the left and right sides, by the guide cover (132) and the limiting protrusion (134). When the winding base (320) is accommodated in the accommodation space (135), the guide rail (330) is accommodated in the support space (136), so that one end in the extension direction, i.e., the front end, can be supported by the front side of the support body (110).

[0231] The guide rail (330) is coupled to the winding base (320). The guide rail (330) is formed to protrude from one side in the thickness direction of the winding base (320), in the illustrated embodiment, from the upper surface.

[0232] The guide rail (330) extends in the direction in which the winding frame (300) is coupled or separated from the support frame (100). In other words, the guide rail (330) extends in the direction in which the winding base (320) moves toward the inlet opening (131), the moving space (133), or the receiving space (135), or in the opposite direction thereto.

[0233] In the illustrated embodiment, the guide rail (330) extends in the forward-backward direction. At this time, the extension length of the guide rail (330), i.e., the length in the forward-backward direction, may be equal to the length of the winding base (320), i.e., the length in the forward-backward direction.

[0234] The guide rail (330) may have a shape corresponding to the shape of the support space (136). In the illustrated embodiment, the guide rail (330) has a polygonal prism shape with a rectangular cross-section and a length in the front-back direction.

[0235] A plurality of guide rails (330) may be provided. The plurality of guide rails (330) may be accommodated in each of the plurality of support spaces (136). In the illustrated embodiment, a pair of guide rails (330) are provided, and are each retractably accommodated in each of the pair of the plurality of support spaces (136). The pair of guide rails (330) are arranged to face each other with the winding body (310) interposed therebetween.

[0236] The winding cavity (340) is a space that accommodates the core member (400). The winding cavity (340) is formed penetrating the interior of the winding body (310) and the winding base (320). The winding cavity (340) is defined by being surrounded by the inner circumference of the winding body (310) and the winding base (320).

[0237] The winding hollow (340) extends in the extension direction of the winding body (310), in the vertical direction in the illustrated embodiment. Each end of the extension direction of the winding hollow (340), in the illustrated embodiment, the upper and lower ends, are each formed open.

[0238] The first core member (400a) can be inserted into the winding hollow (340) through one end in the extension direction of the winding hollow (340), the upper end in the illustrated embodiment. The second core member (400b) can be inserted into the winding hollow (340) through the other end in the extension direction of the winding hollow (340), the lower end in the illustrated embodiment.

[0239] The winding hollow (340) may have a shape corresponding to the shape of the first core member (400a) or the second core member (400b). In the illustrated embodiment, the winding hollow (340) is formed as a polygonal prism-shaped space having a rectangular cross-section and a vertical height.

[0240] Referring again to FIGS. 1 to 3, a bobbin assembly (10) according to an embodiment of the present invention includes a core member (400).

[0241] The core member (400) is magnetized to form a magnetic field for generating an induced current. An induced current is generated by the magnetic field formed by the core member (400), thereby achieving the function of an inductor, i.e., the function of stabilizing the current.

[0242] The core member (400) may be formed of a magnetic material. This is to enhance the strength of the magnetic field formed and the strength of the current induced thereby. In one embodiment, the core member (400) may be formed of a ferrite material.

[0243] In particular, the bobbin assembly (10) according to an embodiment of the present invention may have a larger core member (400) in order to be applied to a large-capacity converter. Even in this case, the core member (400) is stably supported and the coil (C) can be easily wound by the support frame (100), cover frame (200), winding frame (300) and their combined structure described above according to an embodiment of the present invention. A detailed description thereof will be provided later.

[0244] The core member (400) may have any shape that can be inserted into the winding hollow (340) and supported by the winding body (310). In the illustrated embodiment, the core member (400) includes a first portion extending in the left-right direction and a pair of second portions extending in the up-down direction and each end of the first portion is continuous.

[0245] A plurality of core members (400) may be provided. The plurality of core members (400) may be respectively coupled to the support frame (100), the cover frame (200), and the winding frame (300) at different locations. In the illustrated embodiment, the core members (400) are provided as a pair, including a first core member (400a) and a second core member (400b). At this time, the first core member (400a) and the second core member (400b) may be formed to have the same shape.

[0246] The first core member (400a) is positioned on one side of the bobbin assembly (10) in the height direction, that is, on the upper side in the illustrated embodiment. The first core member (400a) is inserted into the winding hollow (340) through the upper end of the winding hollow (340) of the winding frame (300) coupled to the winding frame coupling portion (230).

[0247] At this time, the first part of the first core member (400a) can cover the separation plate (221) of the cover frame (200) and be combined with the cover frame (200). In addition, the second part of the first core member (400a) can penetrate the winding frame coupling portion (230) and be accommodated in the winding hollow (340).

[0248] The second core member (400b) is positioned on the other side in the height direction of the bobbin assembly (10), i.e., the lower side in the illustrated embodiment. The second core member (400b) passes through the core member receiving portion (140) of the support frame (100) and is inserted into the receiving portion (340) through the lower end of the receiving portion (340) of the receiving frame (300) coupled to the receiving portion (130) of the supporting frame (100).

[0249] At this time, the first part of the second core member (400b) covers the lower surface of the support body (110) of the support frame (100) and can be accommodated in the core member receiving portion (140). In addition, the second part of the second core member (400b) can be partially accommodated in the core member receiving portion (140) and accommodated in the winding hollow (340).

[0250] Referring to FIGS. 13 to 20, the process of manufacturing a bobbin assembly (10) according to an embodiment of the present invention and the coupling relationship between each component of the manufactured bobbin assembly (10) are illustrated as examples.

[0251] Referring to Fig. 13, first, a coil (C) is wound on a winding frame (300). A first coil (C1) is wound on a first winding frame (300a), and a second coil (C2), which is connected to the first coil (C1) through a connecting coil (CC), is wound on a second winding frame (300b).

[0252] As described above, the first winding frame (300a) and the second winding frame (300b) may be provided separately from each other. Accordingly, the process of winding the first coil (C1) on the first winding frame (300a) and the process of winding the second coil (C2) on the second winding frame (300b) may be automatically performed by any device or the like.

[0253] Referring to Fig. 14, the winding frame (300) on which the coil (C) has been wound is moved toward one side of the support frame (100) in the width direction, that is, toward the front side in the illustrated embodiment. At this time, the winding base (320) is sequentially moved through the inlet opening (131) and the moving space (133) and is accommodated in the accommodation space (135).

[0254] At this time, the winding frame (300) can be moved until one longitudinal end of the winding base (320), the front end in the illustrated embodiment, comes into contact with the front end of the support body (110). At the same time, the winding frame (300) can be moved until the winding body (310) comes into contact with the rear end of the limiting protrusion (134). Furthermore, the winding frame (300) can be moved until the front end of the guide rail (330) comes into contact with the front end of the support body (110).

[0255] While the winding frame (300) is moved, the winding base (320) and the guide rail (330) can be moved while being supported by the guide cover (132). Accordingly, the movement of the winding frame (300) can be easily performed.

[0256] Referring to Fig. 15, when the coupling of the winding frame (300) and the support frame (100) is completed, the cover frame (200) is coupled to the winding frame (300). The cover frame (200) moves from the upper side to the lower side in the height direction of the bobbin assembly (10) in the illustrated embodiment to cover the coil (C) and is coupled to the winding frame (300).

[0257] One side in the height direction of the winding body (310) of the first and second winding frames (300a, 300b), the upper side in the illustrated embodiment, is inserted into the first and second winding frame connecting portions (230a, 230b), respectively. The winding bodies (310) of the first and second winding frames (300a, 300b) can be inserted into the first and second winding frame connecting portions (230a, 230b), respectively, until the upper end thereof contacts the cover step (212).

[0258] Referring to FIG. 16, the core member (400) is combined with the support frame (100), the cover frame (200), and the winding frame (300).

[0259] At this time, the first core member (400a) positioned on the upper side is moved in the same direction as the movement direction of the cover frame (200), i.e., from the upper side to the lower side, and is coupled with the cover frame (200) and the winding frame (300). The first part of the first core member (400a) is accommodated in a space formed inside the cover body (210), and the second part of the first core member (400a) penetrates the winding frame coupling portion (230) and is inserted into the upper side of the winding hollow (340).

[0260] In addition, the second core member (400b) positioned at the lower side is moved in a direction opposite to the movement direction of the cover frame (200), i.e., from the lower side to the upper side, and is coupled with the support frame (100) and the winding frame (300). The second part of the second core member (400b) is accommodated in the core member receiving portion (140), and the second part of the second core member (400b) penetrates the core member receiving portion (140) and is inserted into the lower side of the winding hollow (340).

[0261] Referring to FIGS. 17 to 20, a bobbin assembly (10) manufactured through the above-described process is illustrated.

[0262] The winding base (320) is accommodated in the moving space (133) and the receiving space (135), and is supported by the upper surface of the support body (110) and the guide cover (132) in surface contact. The guide rail (330) is also at least partially accommodated in the supporting space (136), and is supported by the guide cover (132) and the limiting protrusion (134) in surface contact.

[0263] At this time, the winding base (320) and the guide rail (330) can be supported by making surface contact with the upper surface of the support body (110), the guide cover (132), and the limiting protrusion (134) at multiple points.

[0264] Therefore, the support frame (100) and the winding frame (300) can be easily and stably combined.

[0265] As described above, in an embodiment in which a coupling member (not shown) is provided on the winding base (320) and a fastening member (not shown) is provided on the front side of the support body (110) surrounding the receiving space (135) from the front side, the winding base (320) and the winding frame receiving portion (130) can be more stably coupled.

[0266] In addition, the first winding frame (300a) and the second winding frame (300b) are provided as separate members, and the coil (C) can be wound on each. Accordingly, the first coil (C1) can be automatically wound on the first winding frame (300a). In addition, the second coil (C2), which is connected to the first coil (C1) by the connecting coil (CC), can also be automatically wound on the second winding frame (300b) and then combined with the support frame (100) and the cover frame (200).

[0267] As a result, even when the core member (400) and the coil (C) are enlarged, the coil (C) winding process can be automatically performed by any device, etc. Accordingly, work convenience and efficiency can be improved.

[0268] Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
