The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0050] The present application is described below in conjunction with Figures 1-6 A magnetic ring cooperative integrated anti-interference inductance device is described.

[0051] As Figure 1 shown, in one embodiment, a magnetic ring cooperative integrated anti-interference inductance device includes winding coil 1, pin 2, skeleton 3, bottom plate 4, connecting seat 5 and magnetic ring 6.

[0052] It should be noted that the pin 2 is installed on the two ends of the winding coil 1 in a welded manner.

[0053] The skeleton 3 has a lower end plate 31 for supporting and fixing the winding coil 1.

[0054] It should be noted that the two groups of side walls of the lower end plate 31 are provided with coil receiving grooves.

[0055] The bottom plate 4 has a positioning member 41 installed below the skeleton 3 for providing a rigid mounting base for the skeleton 3.

[0056] The connecting seat 5 has a mounting claw 51 installed on the lower end plate 31 for locking the skeleton 3 to the bottom plate 4.

[0057] The positioning member 41 is a plurality of groups, each group of positioning member 41 includes two groups of positioning strips 41-1 and S-shaped elastic sheets 41-2, the same end of the two groups of positioning strips 41-1 is rotatably installed on the bottom plate 4, the other end of the two groups of positioning strips 41-1 is respectively connected to the two ends of the S-shaped elastic sheet 41-2, the positioning strip 41-1 has a locking groove 41-11, in the initial state, the two groups of positioning strips 41-1 are pushed apart by the S-shaped elastic sheet 41-2 to form a spreader shape.

[0058] Specifically, the locking groove 41-11 matches the width of the mounting claw 51. Preferably, the side wall edge of the locking groove 41-11 is chamfered to facilitate the smooth insertion of the mounting claw 51 into the locking groove 41-11.

[0059] The connecting seat 5 includes a heat dissipation piece 52 and connecting sliding plates 53 symmetrically arranged at both ends of the connecting seat 5. The mounting claw 51 is rotatably mounted at the end of the connecting sliding plates 53 away from each other. The heat dissipation piece 52 is slidably mounted on the top of the connecting seat 5. The top of the connecting sliding plate 53 has a synchronous push plate 53-1, the top end of which is provided in the heat dissipation piece 52, and the bottom end of the lower end plate 31 has a fin connecting piece 31-2.

[0060] It should be noted that the mounting claw 51 and the connecting sliding plate 53 are one-to-one corresponding.

[0061] Specifically, when the anti-interference inductance device based on the magnetic ring is installed on the bottom plate 4, the mounting claw 51 of the connecting seat 5 is aligned and mounted on the positioning strip 41-1. Specifically, the angle of the mounting claw 51 is adjusted to align the mounting claw 51 with the rotating end of the positioning strip 41-1. The mounting claw 51 is pushed onto the positioning strip 41-1. When the mounting claw 51 reaches the position of the locking groove 41-11, the movement of the mounting claw 51 is stopped, and the pre-installation of the connecting seat 5 to the positioning piece 41 is completed. During the movement of the mounting claw 51 to the locking groove 41-11, due to the fact that the two positioning strips 41-1 are in a spread shape at this time, the mounting claw 51 pulls the connecting sliding plate 53 to have a displacement in two directions, i.e., the connecting sliding plate 53 moves away from the connecting seat 5 while moving towards the S-shaped elastic piece 41-2. The connecting sliding plate 53 drives the synchronous push plate 53-1 to move in the direction away from the connecting seat 5, and the synchronous push plate 53-1 drives the heat dissipation piece 52 to move.

[0062] After completing the installation of the connecting seat 5 to the positioning strip 41-1, the skeleton 3 is aligned and clamped into the connecting seat 5. During this process, the fin connecting piece 31-2 of the lower end plate 31 is clamped with the heat dissipation piece 52, and the installation of the skeleton 3 to the connecting seat 5 is completed.

[0063] As shown in FIGS. Figure 2 , Figure 3 and Figure 6 In one embodiment, a first through-hole 42 is provided through the bottom plate 4, and a second through-hole 54 is provided through the connecting seat 5. The inner diameters of the first through-hole 42 and the second through-hole 54 are greater than the outer diameter of the pin 2.

[0064] Specifically, due to the different curvatures of the pins 2, by setting the inner diameters of the first pin hole 42 and the second pin hole 54 to be greater than the outer diameter of the pins 2, the magnetic ring-based anti-interference inductance device is facilitated to be installed to the connecting seat 5 and the pins 2 are facilitated to be installed to the bottom plate 4. Meanwhile, the pins 2 have a certain displacement space in the first pin hole 42 and the second pin hole 54 during the installation process, which reduces the situation that the pins 2 are driven to be angularly offset by the inner walls of the first pin hole 42 or the second pin hole 54 during the installation process of the pins 2, and the welding points between the pins 2 and the winding coil 1 are damaged.

[0065] In the embodiment, the connecting seat 5 includes a first plate body 55 and a second plate body 56. The first plate body 55 is arranged parallel to the bottom plate 4, and the second plate body 56 is symmetrically and perpendicularly arranged at two ends of the first plate body 55.

[0066] The first plate body 55 is provided with a translation channel 55-1 penetrating through the outer wall of the second plate body 56. The connecting slide plates 53 are symmetrically arranged in the translation channel 55-1 and slide in the translation channel 55-1. The opposite ends of the two groups of connecting slide plates 53 are respectively provided with rubber blocks 53-2.

[0067] Preferably, in order to balance the insulation effect and the heat conduction characteristic of the connecting seat 5, the first plate body 55 and the second plate body 56 are made of metal with an insulation layer.

[0068] Specifically, the rubber block 53-2 is arranged in a T shape. The end of the connecting slide plate 53, on which the rubber block 53-2 is arranged, is provided with a T-shaped groove. The rubber block 53-2 is slidingly arranged in the T-shaped groove. The bottom end of the rubber block 53-2 is provided with a first guide surface.

[0069] The inner bottom wall of the translation channel 55-1 is symmetrically provided with a release groove. The release groove is in the shape of an inverted right-angled triangle. The non-right-angled side of the release groove is arranged away from the second pin hole 54. A limiting guide block is penetratingly arranged on the inner bottom wall of the T-shaped groove. The bottom end of the limiting guide block is matched with the shape of the release groove. The top end of the limiting guide block is provided with a second guide surface. The second guide surface is arranged parallel to the first guide surface. When the bottom end of the limiting guide block is located in the release groove, the top end of the limiting guide block is flush with the bottom end of the rubber block 53-2. The rubber block 53-2 is slidable in the T-shaped groove. When the bottom end of the limiting guide block moves out of the release groove, the side wall of the limiting guide block is in contact with the side wall of the rubber block 53-2. The rubber block 53-2 is not slidable in the T-shaped groove.

[0070] In the embodiment, the second plate body 56 is provided with an installation hole 56-1 penetrating therethrough.

[0072] The bottom of the heat dissipation frame 52-1 is lower than the top of the connecting slide plate 53, and the bottom of the heat dissipation frame 52-1 is higher than the top of the positioning strip 41-1.

[0073] The movable fins 52-3 are two groups, which are symmetrically installed at both ends of the heat dissipation frame 52-1, and are installed on the heat dissipation frame 52-1 and can be displaced up and down along the height direction.

[0074] The fixed fins 52-2 are fixedly installed on the heat dissipation frame 52-1, and the fixed fins 52-2 are located between the two groups of movable fins 52-3.

[0075] Specifically, a plurality of fixed fins 52-2 are equidistantly arranged and fixedly installed on the inner wall of the heat dissipation frame 52-1, and the two groups of fixed fins 52-2 arranged in the middle have a driven block on the opposite surfaces, and the top of the connecting slide plate 53 has a T-shaped pressing block. When the connecting slide plate 53 translates into the translation channel 55-1, the T-shaped pressing block moves into the middle of the two groups of fixed fins 52-2, the top of the T-shaped pressing block is attached to the driven block, and the connecting slide plate 53 moves into the translation channel 55-1 at the same time. The limiting effect of the overall height of the heat dissipation piece 52 is achieved, and the heat dissipation piece 52 is installed in the limiting groove 55-2.

[0076] Referring to Figure 3 In this embodiment, the limiting groove 55-2 is in the shape of a convex letter, and the limiting groove 55-2 includes a movable piece descending groove 55-21 and a fixed piece installation groove 55-23.

[0078] In this embodiment, the top of the heat dissipation frame 52-1 has a clamping block 52-12.

[0079] The fin connecting piece 31-2 is two groups, which are symmetrically arranged at the bottom of the lower end plate 31, and the fin connecting piece 31-2 includes a fin connecting block 31-22, a clamping groove 31-24, a driving block 31-26 and a correcting block 31-28. A plurality of fin connecting blocks 31-22 are equidistantly arranged at the bottom of the lower end plate 31, the top of the clamping block 52-12 has a first driving surface 52-11, and the bottom end of the fin connecting block 31-22 has a second driving surface 31-21.

[0080] The engaging slot 31-24 includes an engaging channel 31-25 and a slot 31-27. The engaging channel 31-25 is disposed through the bottom of the lower end plate 31. The width of the engaging channel 31-25 matches the thickness of the engaging block 52-12. The slot 31-27 is connected to the top of the engaging channel 31-25 and the shape of the slot 31-27 matches that of the engaging block 52-12.

[0081] The drive blocks 31-26 are symmetrically located at both ends of the fin connecting blocks 31-22 in the arrangement direction. The straightening block 31-28 is located on the other side of the snap-in channel 31-25 relative to the fin connecting blocks 31-22. The bottom end of the straightening block 31-28 has a third drive surface 31-23.

[0082] like Figure 5 As shown, in one embodiment, the movable fin 52-3 is arranged in an isosceles trapezoidal shape. The lower bottom edge of the movable fin 52-3 is attached to one end of the heat sink 52-1 adjacent to the positioning strip 41-1, and the upper bottom edge of the movable fin 52-3 is attached to one end of the heat sink 52-1 away from the positioning strip 41-1. The non-right-angle waist of the movable fin 52-3 is located at the bottom of the movable fin 52-3.

[0083] The bottom of the movable fin 52-3 has an inverted L-shaped limiting opening 52-31.

[0084] When the locking block 52-12 moves up and down along the locking channel 31-25, the vertical inner wall of the inverted L-shaped limiting port 52-31 is located above the moving plate lower groove 55-21.

[0085] When the snap-fit ​​block 52-12 enters the slot 31-27, the vertical inner wall of the limiting port 52-31 and the side wall of the first plate 55 are on the same vertical plane, and at this time the two sets of positioning strips 41-1 are in the shape of "11", and the two sets of positioning strips 41-1 are respectively attached to the side wall of the corresponding movable fin 52-3.

[0094] When the moving installation claw 51 moves on the position of the positioning strip 41-1, because the two groups of positioning strips 41-1 are arranged in a spread shape, the two groups of installation claws 51 are pulled by the positioning strip 41-1 to move in the direction away from the connecting seat 5 in the process of moving along the positioning strip 41-1, the installation claw 51 drives the connecting sliding plate 53 to move together, which drives the connecting sliding plate 53 and the rubber block 53-2 to move to the channel opening of the translation channel 55-1, and the two groups of rubber blocks 53-2 are driven away from the first pin hole 42 and the second pin hole 54, so that in the installation of the anti-interference inductance device based on the magnetic ring cooperation integration, the pin 2 can be smoothly inserted into the first pin hole 42 and the second pin hole 54.

[0095] In the above process, the connecting slide plate 53 drives the heat dissipation piece 52 to move away from the connecting seat 5 by synchronously pushing the slide plate 53-1, so that the heat dissipation piece 52 is translated relative to the L-shaped limiting block 55-22 to a position where the inner wall of the fixed fin 52-2 is in contact with the side wall of the L-shaped limiting block 55-22, so that in the process of moving the lower end plate 31 downward, the fin connecting piece 31-2 can be smoothly clamped on the heat dissipation piece 52.

[0096] In the process of installing the skeleton 3 to the connecting seat 5, if the installation claw 51 has not moved to the position of the locking groove 41-11 and the inner wall of the fixed fin 52-2 has been in contact with the side wall of the L-shaped limiting block 55-22, continue to move the connecting seat 5 to continuously displace the installation claw 51 along the positioning strip 41-1, and rotate the positioning strip 41-1 inward by a certain angle to move the installation claw 51 to a position capable of being engaged with the locking groove 41-11. In the subsequent process of moving the lower end plate 31 downward relative to the heat dissipation piece 52, the fin connecting piece 31-22 first abuts against the bottom end of the clamping block 52-12 on the heat dissipation piece 52, and the second driving surface 31-21 of the fin connecting piece 31-22 extrudes the first driving surface 52-11 to make the heat dissipation piece 52 translate as a whole away from the installation claw 51, so that the top end of the clamping block 52-12 enters the clamping channel 31-25, and the fin connecting piece 31-22 smoothly moves downward through the gap between the fixed fins 52-2. As the lower end plate 31 continuously moves downward, the clamping block 52-12 moves upward in the clamping channel 31-25, and the fin connecting piece 31-22 moves downward between the fixed fins 52-2, and the driving block 31-26 begins to abut against the top of the movable fin 52-3.

[0097] If the installation claw 51 has moved to the position of the locking groove 41-11 and the fixed fin 52-2 has not been in contact with the side wall of the L-shaped limiting block 55-22, in the process of moving the lower end plate 31 downward relative to the heat dissipation piece 52, the correction block 31-28 first abuts against the top end of the clamping block 52-12, and the third driving surface 31-23 of the correction block 31-28 extrudes the clamping block 52-12 to displace the heat dissipation piece 52 in the horizontal direction to adjust the displacement, so that the clamping block 52-12 is aligned with the clamping channel 31-25.

[0098] With the lower end plate 31 continuously descending, the driving block 31-26 pressed on the top end of the movable fin 52-3 follows the descending, the movable fin 52-3 is pushed by the driving block 31-26 to descend, the bottom end of the movable fin 52-3 descends through the movable fin descending groove 55-21 and abuts against the side wall of the connecting slide plate 53, the bottom inclined surface of the movable fin 52-3 extrudes the connecting slide plate 53, prompting the connecting slide plate 53 to be extruded and displaced into the translation channel 55-1, when the connecting slide plate 53 moves to the limiting opening 52-31 of the movable fin 52-3, at this time, the connecting slide plate 53 is completely extruded into the translation channel 55-1, and the side wall of the connecting slide plate 53 leaves a spacing with the channel opening of the translation channel 55-1. In this process, the connecting slide plate 53 is displaced inward by the traction of the mounting claw 51, the mounting claw 51 pulls the positioning strip 41-1 to rotate inward and extrudes the S-shaped elastic sheet 41-2 in the middle, so that the positioning strip 41-1 initially in the outer swing state is pulled by the mounting claw 51 to rotate to be parallel to the second plate body 56 and then continuously rotate inward by a certain angle, at this time, the positioning strip 41-1 is below the heat dissipation frame 52-1 in the height direction.

[0099] In the process of moving the connecting slide plate 53 into the translation channel 55-1, the connecting slide plate 53 drives the limiting guide block and the rubber block 53-2 to approach the lead 2, when the limiting guide block moves to the position aligned with the release slot, the bottom end of the limiting guide block moves into the release slot, and the rubber block 53-2 is slidable in the T-shaped slot.

[0100] Subsequent lower end plate 31 continues to descend, and clamping block 52-12 moves upward along the clamping channel 31-25 to a position aligned with the clamping slot 31-27. At this time, the positioning strip 41-1 is subjected to a reverse rotation force by the S-shaped elastic piece 41-2, and the connecting slide plate 53 is also subjected to a reverse force by the rubber block 53-2 pressed on both sides of the pin 2, which promotes the reverse movement of the connecting slide plate 53 when the clamping block 52-12 is highly aligned with the clamping slot 31-27, and pushes the movable fin 52-3 to move reversely. The movable fin 52-3 translates the clamping block 52-12 into the clamping slot 31-27 through the heat dissipation frame 52-1. At the same time, the connecting slide plate 53 drives the mounting claw 51 to move reversely, which promotes the reverse rotation of the positioning plate that originally has a reverse rotation tendency by a certain angle. At this time, the positioning strip 41-1 is turned to an angle that fits the side wall of the movable fin 52-3. When the heat dissipation frame 52-1 moves reversely, it synchronously moves the L-shaped rod 52-14, and the first inclined surface 52-13 of the L-shaped rod 52-14 moves horizontally along the second inclined surface 56-11 of the displacement guide block 56-12 while moving downward, which promotes the bottom end of the L-shaped rod 52-14 to move downward to a position lower than the top of the positioning strip 41-1, so that the positioning strip 41-1 is clamped between the vertical rod body of the L-shaped rod 52-14 and the movable fin 52-3. At this time, the positioning strip 41-1 blocks the inward movement of the L-shaped rod 52-14, and further prevents the inward movement of the heat dissipation frame 52-1 to block the clamping block 52-12 from moving out of the clamping slot 31-27, thereby locking the connection between the lower end plate 31 and the heat dissipation piece 52. At this time, the positioning strip 41-1 fits the side wall of the movable fin 52-3, which can transfer part of the heat generated by the bottom plate 4 to the movable fin 52-3 to accelerate the heat dissipation of the bottom plate 4. Moreover, the bottom end of the vertical rod body of the L-shaped rod 52-14 is located in the reverse rotation path of the positioning strip 41-1, which can prevent the reverse rotation of the positioning strip 41-1, so that the positioning strip 41-1 remains in contact with the movable fin 52-3, and the rubber block 53-2 remains in contact with both sides of the pin 2 to protect the pin 2 and reduce the deformation of the pin 2 caused by external force.

[0101] During the process of clamping block 52-12 clamping into clamping slot 31-27, the connecting slide plate 53 translates to the channel opening of the translation channel 55-1, and the connecting slide plate 53 drives the limiting guide block to move out of the release slot. During the upward movement of the release slot, the rubber block 53-2 is pushed to move towards the pin 2, thereby achieving the clamping effect of the rubber block 53-2 on the pin 2.

[0102] When the inductance device needs to be detached from the bottom plate 4, the positioning strip 41-1 is pinched at one end adjacent to the S-shaped elastic sheet 41-2, the positioning strip 41-1 is rotated inward and the movable fin 52-3 is pushed inward, the movable fin 52-3 drives the clamping block 52-12 to move out of the clamping groove 31-27 through the heat dissipation frame 52-1. In this process, the bottom end of the limiting guide block moves into the release slot again, the limiting of the rubber block 53-2 is released, and then the clamping state of the rubber block 53-2 to the pin 2 is released, so as to facilitate the upward movement of the inductance device as a whole to separate from the connecting seat 5.

[0103] Referring to Figure 1 In the embodiment, the anti-interference inductance device based on the magnetic ring cooperative integration further comprises a magnetic ring 6, the magnetic ring 6 is tightly sleeved and installed on the framework 3, and the magnetic ring 6 and the winding coil 1 are distributed in an up-down manner on the framework 3.

[0104] Specifically, by increasing the magnetic ring 6 to reduce the magnetic flux dispersion range of the magnetic core inductance, the magnetic flux interference between inductances can be reduced, the inductance precision of the magnetic core inductance in the whole working current range can be improved, and the distribution density of the inductance in space can be increased.
