Description

Technical Field

[0001] The utility model relates to the field of inductors, in particular to a base and a common-mode inductor thereof. Background Art

[0002] For a common-mode inductor, it includes a coil winding, a coil bracket, and a base body for mounting the coil bracket. Among them, in the preparation process of most common-mode inductors, an epoxy board is selected as the base body of the coil bracket. However, such a method requires an additional positioning tooling during the actual installation process. Moreover, as the base body, the epoxy board is difficult to ensure the balance of the coil bracket.

[0003] Among them, when the epoxy board is used as the base body of the common-mode inductor, it is difficult to ensure the consistency of the common-mode inductor product during the production process, and the assembly time of the common-mode inductor product is relatively long during the actual assembly process. At the same time, due to the lack of corresponding limiting structures in the existing base body, additional positioning tooling needs to be added, thereby increasing the corresponding production cost.

[0004] The present utility model is precisely generated based on the above deficiencies. Content of the Utility Model

[0005] The purpose of the present utility model is to overcome the problems of the prior art and provide a base that is convenient to install and can ensure the stable installation of the coil bracket and the base body.

[0006] The present utility model also provides a common-mode inductor that is convenient to install and can ensure the stable installation of the coil bracket and the base body.

[0007] In order to achieve the above purpose, the present utility model adopts the following solutions:

[0008] The first aspect of the present utility model provides a base, including: a base body, a coil bracket is connected to the base body, a protruding positioning portion is provided on the coil bracket, a connection structure capable of positioning the coil bracket is provided between the coil bracket and the base body, the connection structure includes a plurality of sliders slidably connected to the base body, a clamping position for the positioning portion to be inserted is provided on the slider, and a synchronous component rotatably connected to each slider and capable of driving each slider to move synchronously along the base body is further provided between the plurality of sliders.

[0009] The described synchronization component includes first protrusions provided on each of the sliders. The synchronization component further includes a rotating member rotatably connected to the base body. Second protrusions are provided on the rotating member. A connecting member capable of rotatably connecting with the first and second protrusions is provided between each of the first protrusions and the second protrusions. An activity groove capable of allowing the first protrusion or the second protrusion to be inserted and move therein is provided on the connecting member. When the rotating member rotates relative to the base body, the rotating member can drive each first protrusion to move, thereby causing each slider to slide relative to the base body.

[0010] A connecting plate extending outward is provided on the inner wall of the through groove of the coil support. The positioning portion includes a first connecting piece and a second connecting piece connected to one end of the connecting plate and extending obliquely outward, and the positioning portion further includes a third connecting piece and a fourth connecting piece connected to the other end of the connecting plate and extending obliquely outward.

[0011] The connecting plate and the positioning portion divide the through groove of the coil support into two equal wire passing holes.

[0012] The connecting plate and the positioning portion are arranged in an X shape.

[0013] The clamping position is an open clamping groove, and a rough surface capable of contacting the positioning portion is provided on the groove wall of the clamping position.

[0014] A plurality of connecting frames are further provided between the base body and the coil support. Clamping convex blocks protruding from both the left and right sides of the connecting plate are provided. A clamping groove capable of allowing the clamping convex blocks to be inserted is provided on the connecting frame. A plurality of buckles are further provided at the lower end of the connecting frame, and a clamping hole capable of allowing the buckles to be inserted is provided on the base body.

[0015] A screw assembly capable of connecting the base body and the rotating member is provided between the base body and the rotating member.

[0016] The coil support, the connecting plate, the first connecting piece, the second connecting piece, the third connecting piece and the fourth connecting piece are an integrally formed integral structure.

[0017] In a second aspect of the present invention, a common mode inductor is provided, including: the base as described above. A coil winding is further connected to the coil support. Pins are provided on each of the coil windings. A plurality of through holes capable of allowing the pins to pass through are provided on the base body.

[0018] Compared with the existing technology, the present invention has the following advantages:

[0019] 1. When the present structure is adopted, the positioning part on the coil support is aligned with the engaging position on each slider, and then the coil support is inserted into the slider. In the process of inserting the coil support into the slider, a plurality of sliders are synchronously slid relative to the base body through the synchronization component to adjust the position on the base body, so that the coil support can be accurately fixed, ensuring the correct placement and fixation of the coil support, avoiding the situation that the coil support is tilted or the installation position does not correspond when it is placed, and at the same time, the design of the sliding connection simplifies the adjustment process of the coil support, so that the user can easily adjust the position of the coil as needed, and through the cooperation of the slider and the positioning part, the base body is allowed to be applicable to coil bodies of various different specifications, which increases the versatility and applicability of the base and has a wider range of uses.

[0020] 2. When the rotating member rotates relative to the base body, it can drive the second protrusion on it to rotate. When the second protrusion rotates, it drives the connecting member to move. When the connecting member moves, it pushes the first protrusion to move, so that the two sliders move synchronously along the base body. The design of the synchronization component ensures that each slider can move at the same time, improves the stability and consistency of the coil support, and avoids the imbalance caused by the independent movement of individual sliders. The user only needs to operate the rotating member to achieve the synchronous movement of all sliders, which simplifies the adjustment process, improves the convenience of operation, and improves the accuracy of the coil support positioning. By accurately controlling the movement of the slider, the space of the base body can be used more effectively to adapt to coil supports of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following further describes the present utility model in detail with reference to embodiments:

[0028] The following further describes in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] As Figures 1 to 5 shown, in the first aspect of the present utility model, a base is provided, including: a base body 1, a coil bracket 2 is connected to the base body 1, a protruding positioning portion 21 is provided on the coil bracket 2, and a connecting structure 3 capable of positioning the coil bracket 2 is provided between the coil bracket 2 and the base body 1. The connecting structure 3 includes a plurality of sliders 31 slidably connected to the base body 1, and a clamping position 311 capable of allowing the positioning portion 21 to be inserted is provided on the slider 31. A synchronization component 32 rotatably connected to each of the sliders 31 and capable of driving each of the sliders 31 to move synchronously along the base body 1 is further provided between the plurality of sliders 31.

[0030] When adopting this structure, align the positioning portion 21 on the coil bracket 2 with the clamping positions 311 on each slider 31, and then insert the coil bracket 2 onto the slider 31. During the process of inserting the coil bracket 2 onto the slider 31, the plurality of sliders 31 synchronously slide relative to the base body 1 through the synchronization component 32 to adjust their positions on the base body 1, so that the coil bracket 2 can be accurately fixed, ensuring the correct placement and fixation of the coil bracket 2, avoiding the situation of tilting or incorrect installation position when the coil bracket 2 is placed. At the same time, the design of the sliding connection simplifies the adjustment process of the coil bracket 2, enabling the user to easily adjust the position of the coil according to needs. Moreover, through the cooperation of the slider 31 and the positioning portion 21, the base body 1 is allowed to be applicable to various different specifications of coil bodies, increasing the versatility and applicability of the base, and having a wider range of use.

[0031] The synchronization component 32 includes a protrusion 321 provided on each of the sliders 31, and the synchronization component 32 also includes a rotating member 322 rotatably connected to the base body 1, and the rotating member 322 is provided with a movable groove 3221 for each of the protrusions 321 to be inserted and move therein, and when the rotating member 322 rotates relative to the base body 1, the rotating member 322 can drive each of the protrusions 321 to move, thereby causing each of the sliders 31 to slide relative to the base body 1.

[0032] The synchronization component 32 includes a first protrusion 321 provided on each of the sliders 31, and the synchronization component 32 also includes a rotating member 322 rotatably connected to the base body 1, and a second protrusion 3321 is provided on the rotating member 322, and a connecting member 323 that can be rotatably connected to the first protrusion 321 and the second protrusion 3321 is provided between the first protrusion 321 and the second protrusion 3321, and a movable groove 3231 is provided on the connecting member 323, in which the first protrusion 321 or the second protrusion 3321 can be inserted and moved, and when the rotating member 322 rotates relative to the base body 1, the rotating member 322 can drive each first protrusion 321 to move, thereby causing each slider 31 to slide relative to the base body 1. When the rotating member 322 rotates relative to the base body 1, it can drive the second protrusion 3321 thereon to rotate. When the second protrusion 3321 rotates, it drives the connecting member 323 to move. When the connecting member 323 moves, it pushes the first protrusion 321 to move, thereby making the two sliders 31 move synchronously along the base body 1. The design of the synchronization component 32 ensures that each slider 31 can move simultaneously, improves the stability and consistency of the coil support 2, and avoids the imbalance caused by the independent movement of individual sliders 31. The user only needs to operate the rotating member 322 to achieve the synchronous movement of all sliders 31, which simplifies the adjustment process, improves the convenience of operation, and improves the accuracy of the positioning of the coil support 2. By accurately controlling the movement of the slider 31, the space of the base body 1 can be more effectively utilized to adapt to coil supports 2 of different sizes.

[0033] A connecting plate 23 is extended outwardly on the inner wall of the through groove 22 of the coil bracket 2, and the positioning portion 21 includes a first connecting piece 211 and a second connecting piece 212 connected to one end of the connecting plate 23 and extending outwardly at an angle, and the positioning portion 21 also includes a third connecting piece 213 and a fourth connecting piece 214 connected to the other end of the connecting plate 23 and extending outwardly at an angle.

[0034] The connecting plate 23 and the positioning portion 21 divide the through slot 22 of the coil support 2 into two equally divided wire holes 221. By dividing the through slot 22 into two equally divided wire holes 221, the design may achieve symmetry, which helps to maintain the balance and stability of the coil support 2. At the same time, the equally divided design may help to optimize the arrangement of the coil winding on the coil support 2, making the coil winding more neat and orderly.

[0035] The connecting plate 23 and the positioning part 21 are arranged in an X shape, which is convenient for processing and can limit the inclination angle of the positioning part 21 extending obliquely.

[0036] The clamping position 311 is an open slot, and a rough surface 3111 capable of contacting the positioning part 21 is provided on the slot wall of the clamping position 311. The clamping position 311 being an open slot facilitates the quick installation of the positioning part 21. The rough surface 3111 on the slot wall of the clamping position 311 may provide better friction, which helps to fix the positioning part 21 and prevent the coil bracket 2 from shifting during use.

[0037] A plurality of connecting frames 4 are further provided between the base body 1 and the coil bracket 2. Clamping bumps 231 protruding from both the left and right sides of the connecting plate 23 are provided. A slot 41 for the clamping bumps 231 to fit into is provided on the connecting frame 4. A plurality of buckles 42 are further provided at the lower end of the connecting frame 4, and a card hole 11 for the buckles 42 to snap into is provided on the base body 1. Two connecting frames 4 are arranged on both sides of the coil bracket 2 to prevent the coil bracket 2 from disengaging from the clamping position 311 laterally, which is safer. It can be quickly installed on the base body 1 through the buckles 42, making the connection more convenient. At the same time, the clamping bumps 231 and the slots 41 are used for cooperation to quickly position the connecting frame 4 and the coil bracket 2.

[0038] A screw assembly 5 capable of connecting the base body 1 and the rotating part 322 is provided therebetween. The connection is faster and more stable.

[0039] The coil bracket 2, the connecting plate 23, the first connecting piece 211, the second connecting piece 212, the third connecting piece 213 and the fourth connecting piece 214 are of an integrally formed overall structure, which is more convenient for processing.

[0040] Such as Figures 1 to 5As shown, the second aspect of the present utility model provides a common mode inductor, comprising: the base as described above, a coil winding 6 is further connected to the coil bracket 2, pins 61 are provided on each of the coil windings 6, and a plurality of through holes 12 through which the pins 61 can pass are provided on the base body 1. When adopting this structure, align the positioning portion 21 on the coil bracket 2 with the clamping positions 311 on each slider 31, and then snap the coil bracket 2 onto the slider 31. During the process of snapping the coil bracket 2 onto the slider 31, the plurality of sliders 31 slide synchronously relative to the base body 1 through the synchronous component 32 to adjust their positions on the base body 1, so that the coil bracket 2 can be accurately fixed, ensuring the correct placement and fixation of the coil bracket 2, avoiding the situation of tilting or incorrect installation position when the coil bracket 2 is placed. At the same time, the design of the sliding connection simplifies the adjustment process of the coil bracket 2, enabling the user to easily adjust the position of the coil as needed. Moreover, through the cooperation of the slider 31 and the positioning portion 21, the base body 1 is allowed to be applicable to coil bodies of various different specifications, increasing the versatility and applicability of the base and having a wider range of use. At the same time, the setting of the plurality of through holes 12 can accommodate pins 61 of different designs.
