Description

Technical Field

[0001] The invention relates to a vertical integrated inductor, belonging to the technical field of inductors. Background Art

[0002] The original model of the inductor element is a cylindrical coil wound with a wire. When a current i flows through the coil, a magnetic flux Φ is generated in the coil and energy is stored. The electromagnetic induction of the inductor element is divided into self-induction and mutual induction. The electromagnetic induction phenomenon caused by the change of magnetic flux generated by its own magnetic field in the coil is called "self-induction"; the electromagnetic induction phenomenon caused by the change of magnetic flux in the coil caused by the external magnetic field is called "mutual induction".

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1: Figure 1-Figure 10 As shown, a vertical integrated inductor is provided, including a housing 1, a bottom plate 2 is attached to the lower end of the housing 1, and a mounting carrier is provided for a positioning frame 21 and other components through the bottom plate 2, and the positioning frame 21 attached to the inner wall of the housing 1 is installed on the upper end of the bottom plate 2, and the housing 1 and the bottom plate 2 are positioned and installed through the positioning frame 21, and the outer end surfaces around the positioning frame 21 are all recessed inward to form a first threaded hole 22, and the first threaded hole 22 provides an installation space for the first bolt 11, and the outer end surfaces around the housing 1 are The first bolt 11 is recessed inward to form a stepped hole 12 extending to the inner wall of the housing 1 and connected to the outer end of the first threaded hole 22. The first bolt 11 is passed through the housing 1 through the stepped hole 12, and the cap of the first bolt 11 is hidden. Then, the rod of the first bolt 11 with the cap located in the stepped hole 12 is passed through the stepped hole 12 and is threadedly connected to the first threaded hole 22. The first bolt 11 and the first threaded hole 22 are used in conjunction with each other to fasten the housing 1 and the positioning frame 21, thereby making the bottom plate 2 and the housing 1 detachable and connected.

[0041] The positioning column 6 is installed on the middle part of the front end of the mounting plate 5 located in the housing 1. The mounting plate 5 is used to provide a mounting carrier for the positioning column 6 and other components. The inside of the metal coil 4 is positioned through the positioning column 6, and the metal coil 4 attached to the front end of the mounting plate 5 is sleeved on the outer end of the positioning column 6. The metal coil 4 is used to generate magnetic flux, and then the vertical parts of the two relatively arranged L-shaped terminal plates 3, which are located on the lower side of the first arc plate 51 and extend out of the lower side of the mounting plate 5 and are integrated with the metal coil 4 and located on the inner side of the positioning frame 21, are respectively installed on the front and rear ends of the metal coil 4. The two L-shaped terminal plates 3 are used in combination to enable the external power supply to transmit current to the metal coil 4;

[0042] The first curved plate 51 which is attached to the lower outer end of the metal coil 4 and is located between the two L-shaped terminal plates 3 is set on the front end of the mounting plate 5, and the second curved plate 52 which is attached to the upper outer end of the metal coil 4 is installed on the front end of the mounting plate 5. The first curved plate 51 and the second curved plate 52 are used together to position the outside of the metal coil 4, and the mounting plate 5, the positioning column 6, the first curved plate 51 and the second curved plate 52 are integrated. The design of the integrated structure is convenient for production. The rear end surface of the mounting plate 5 is recessed forward to form a concave hole extending into the positioning column 6 and located on the rear side of the third threaded hole 66. The concave hole reduces the production amount of the mounting plate 5 and the positioning column 6.

[0043] Two through grooves 23 are formed on the upper end surface of the bottom plate 2, and the vertical parts of the two L-shaped terminal plates 3 pass through the two through grooves 23 respectively. Through the through grooves 23, on the one hand, an installation space is provided for the insulating plate 32, and on the other hand, the L-shaped terminal plate 3 passes through the bottom plate 2, and the two insulating plates 32 installed on the upper ends of the horizontal parts of the L-shaped terminal plate 3 are respectively arranged in the two through grooves 23, and the contact part of the L-shaped terminal plate 3 is isolated from the metal coil 4 by the insulating plate 32;

[0044] The upper end surfaces of the lateral parts of the two L-shaped terminal plates 3 are recessed downward to form a U-shaped groove 31 penetrating the lateral part of the L-shaped terminal plates 3. The screws are passed through the lateral part of the L-shaped terminal plates 3 through the U-shaped groove 31. The lower end surfaces of the two insulating plates 32 are recessed upward to form a second threaded hole 33 connected to the upper end of the U-shaped groove 31. The second threaded hole 33 is used to provide installation space for the screws. Two limit plates 34 located at the upper end of the base plate 2 and arranged on the inner end of the vertical part of the L-shaped terminal plate 3 and located on the lower side of the mounting plate 5 are respectively arranged on the upper ends of the two insulating plates 32. The insulating plates 32 and the base plate 2 are limitedly installed through the limit plates 34.

[0045] During manufacturing, the spiral metal material is firstly put onto the outer end of the positioning column 6, and the metal material is made to fit with the front end of the mounting plate 5. At this time, the metal material is located in the outer cylinder structure formed by the first arc plate 51 and the second arc plate 52. The metal material is then pressed by vertical cold pressing to press out the metal coil 4, and the two ends of the metal material are bent, and then two L-shaped terminal plates 3 extending from the lower side of the mounting plate 5 are manufactured at both ends of the front end of the metal coil 4. During the vertical pressing process of the metal coil 4, the positioning column 6 and the outer cylinder structure formed by the first arc plate 51 and the second arc plate 52 will position the pressed metal coil 4.

[0046] The metal coil 4 can be vertically positioned and pressed to effectively reduce the vertical and horizontal dimensions of the product, increase the number of high-performance components on the circuit board, effectively reduce the probability of defects such as damage, displacement, and cracking during the pressing of the metal coil 4, increase the pressing quality of the metal coil 4, and thus improve the inductance and saturation performance of the subsequently assembled product;

[0047] Then, the two L-shaped terminal plates 3 are respectively passed through the two through grooves 23 on the bottom plate 2, and then the two insulating plates 32 are respectively installed in the two through grooves 23. At this time, the two limiting plates 34 are set on the upper end of the bottom plate 2, and the two limiting plates 34 are respectively installed on the inner ends of the vertical parts of the two L-shaped terminal plates 3, and the insulating plates 32 and the through grooves 23 are limitedly installed, and the L-shaped terminal plates 3 and the through grooves 23 are limitedly installed, and then the transverse parts of the two L-shaped terminal plates 3 are respectively set on the lower ends of the two insulating plates 32;

[0048] The positioning and limited installation between the L-shaped terminal board 3 and the bottom plate 2 are realized, and the probability of defects such as tilting with the mounting surface of the circuit board during subsequent connection caused by deformation of the L-shaped terminal board 3 due to positioning and pressing is effectively reduced, and the use effect is improved, and the electrical performance of the product after installation is effectively guaranteed. In addition, the insulating plate 32 is used to insulate and isolate the lateral part of the L-shaped terminal board 3 from the metal coil 4, which effectively reduces the probability of interference between the magnetic flux generated by the metal coil 4 and the electrical performance of the mounting position of the L-shaped terminal board 3, and effectively guarantees the use effect of the product;

[0049] After the L-shaped terminal board 3 is installed between the bottom plate 2, the shell 1 is placed on the bottom plate 2, and the metal coil 4 and other components installed on the bottom plate 2 are protected by the shell 1, and then the four first bolts 11 are respectively passed through the four step holes 12 and are respectively threadedly connected with the four first threaded holes 22, so that the shell 1 and the positioning frame 21 are fastened and installed, so that the product is integrated, and the shell 1 and the bottom plate 2 are conveniently disassembled and assembled, and the internal components of the shell 1 can be inspected or maintained without disassembling the L-shaped terminal board 3;

[0050] After the shell 1 is installed between the base plate 2, one mounting method is to weld the lateral parts of the two L-shaped terminal boards 3 located at the lower end of the base plate 2 to the mounting surface of the circuit board by welding, so as to realize full contact installation between the product and the circuit board, with high installation stability and effectively guaranteeing the use effect of the product. Another mounting method is to place the lateral parts of the two L-shaped terminal boards 3 located at the lower end of the base plate 2 on the mounting surface of the circuit board, and then screw through the circuit board and the U-shaped groove 31 and threadedly connect them with the second threaded hole 33, so as to realize convenient disassembly and assembly between the product and the circuit board, facilitate replacement and maintenance, and effectively guarantee the use effect of the circuit board.

[0051] Embodiment 2: A vertical cold pressing method is used and a structure formed by a mounting plate 5, a positioning column 6, a first arc plate 51 and a second arc plate 52 is adopted to perform vertical positioning pressing to produce a metal coil 4. However, the metal coil 4 that has just been pressed is prone to residual elasticity due to its positioning on the structure. As a result, under the effect of the residual elasticity, the produced metal coil 4 is more likely to have defects such as gaps and deformations along the positioning column 6, thereby affecting the pressing quality of the metal coil 4.

[0052] In order to solve the above problems, Figure 2 , Figure 6 , Figure 8 , Fig. 9 , Fig.11 , Fig.12 and Fig.13 As shown, the front end surface of the positioning column 6 is recessed backward to form a functional groove 64, through which a mounting space is provided for components such as the tapered column 62, and the rear wall surface of the inner part of the functional groove 64 is recessed backward to form a third threaded hole 66, through which a mounting space is provided for the second bolt 63, and the annular inner wall surface of the functional groove 64 is recessed outward to form a plurality of large grooves 67, through which the T-block 61 is limited, and the annular end surface of the positioning column 6 is recessed inward to form a plurality of large grooves 67 connected to the small grooves 65, and the large grooves 67 are used in conjunction with the small grooves 65 to allow the T-block 61 to pass through the positioning column 6;

[0053] A plurality of T-shaped blocks 61 are evenly mounted on the outer end of the positioning column 6, with the small blocks extending inwardly into the plurality of small grooves 65, the large blocks passing through the large grooves 67, and the large blocks extending inwardly into the functional grooves 64. The plurality of T-shaped blocks 61 are used in combination to restrict the installation between the metal coil 4 and the positioning column 6, and the rod of the second bolt 63 located in the functional groove 64 is threadedly connected with the third threaded hole 66. The second bolt 63 is used to provide a mounting carrier for the tapered column 62, and the tapered column 62 is moved, and then the tapered column 62 arranged to be wide at the front and narrow at the back is arranged on the outer end of the rod of the second bolt 63;

[0054] A third inclined surface 613 is provided at the inner end of the large block portion of the multiple T-blocks 61, which is fitted on the outer end of the inclined portion of the conical column 62. The third inclined surface 613 is used in conjunction with the conical column 62 to drive the multiple T-blocks 61 to move outward. A second inclined surface 612 extending into the small groove 65 is provided at the front corners of the outer ends of the small block portions of the multiple T-blocks 61, and the multiple second inclined surfaces 612 form a conical structure with a narrow front and a wide rear. The multiple second inclined surfaces 612 are used in conjunction to facilitate the assembly between the metal coil 4 and the positioning column 6. A first inclined surface 611 located on the rear side of the second inclined surface 612 is provided at the rear corners of the outer ends of the small block portions of the multiple T-blocks 61, and the multiple first inclined surfaces 611 form a conical structure with a wide front and a narrow rear. The multiple first inclined surfaces 611 are used in conjunction to facilitate the movement of the T-block 61 to the front end of the metal coil 4.

[0055] First, a metal material in a spiral state is fitted onto the outer end of the positioning column 6. During the fitting process, the metal material first contacts the plurality of second inclined surfaces 612, and the metal material and the second inclined surfaces 612 move relative to each other, so that the plurality of T-blocks 61 move inward along the channels formed by the plurality of large grooves 67 and the small grooves 65, respectively, so that the small block portion of the T-block 61 completely enters the small groove 65, so that the metal material is effectively fitted onto the outer end of the positioning column 6 and contacts the front end of the mounting plate 5, and then the metal material fitted onto the outer end of the positioning column 6 is pressed, and the metal material is pressed into a metal coil 4;

[0056] Then, the second bolt 63 is rotated. Since the second bolt 63 is threadedly connected with the third threaded hole 66, the second bolt 63 rotates and moves backwards at the same time, thereby causing the tapered column 62 to move backwards, and causing the inclined portion of the tapered column 62 to move relative to the plurality of third inclined surfaces 613, thereby causing the plurality of T-blocks 61 to move outwards along the channels formed by the plurality of large grooves 67 and the small grooves 65, respectively, and with the assistance of the plurality of first inclined surfaces 611, causing the plurality of T-blocks 61 to move to the front end of the coil, and at the same time causing the large block portion of the T-block 61 to contact the outer wall of the inner portion of the large groove 67 toward the outer end, thereby limiting the installation of the T-block 61 and the positioning column 6;

[0057] The pressed metal coil 4 can be shaped, and the probability of defects such as gaps and deformations in the pressed metal coil 4 due to factors such as residual elasticity can be effectively reduced, thereby effectively ensuring the pressing quality of the metal coil 4 and further effectively ensuring the use effect of the product.

[0058] Embodiment 3: A vertical pressing method is adopted to produce the metal coil 4. In order to ensure that the metal coil 4 can be effectively mounted on the circuit board, the pins of the metal coil 4 are generally bent to increase the mounting area between the pins and the circuit board. However, the bent portion of the pin is prone to thinning due to bending, resulting in pressure on the bent portion under the action of the weight of the metal coil 4 and other components after mounting, resulting in a high probability of cracking, deformation and other defects at the bent portion of the pin, affecting the use effect of the product.

[0059] In order to solve the above problems, Fig.14 and Fig.15 As shown, two relatively arranged second U-shaped plates 36 located in the positioning frame 21 are both installed on the upper end of the base plate 2, so that the two lateral parts of the second U-shaped plates 36 are arranged on the outward end of the limiting plate 34, and the vertical part of the L-shaped terminal plate 3 passes through the cavity formed by the second U-shaped plate 36 and the limiting plate 34, and the second U-shaped plate 36 is used in conjunction with the limiting plate 34 to wrap the upper part of the bending position of the L-shaped terminal plate 3, and two relatively arranged first U-shaped plates 35 are installed on the lower end of the base plate 2, so that the two first U-shaped plates 35 are respectively arranged on the outer ends of the lateral parts of the two L-shaped terminal plates 3, and the lower part of the bending position of the L-shaped terminal plate 3 is wrapped by the first U-shaped plate 35.

[0060] First, the two first U-shaped plates 35 and the two second U-shaped plates 36 are respectively installed on the upper and lower ends of the bottom plate 2, and then the two L-shaped terminal plates 3 are respectively inserted into the two through grooves 23 on the bottom plate 2, and then the two insulating plates 32 are respectively installed in the two through grooves 23. At this time, the two limit plates 34 are set on the upper end of the bottom plate 2, and the two limit plates 34 are respectively installed on the vertical parts of the two L-shaped terminal plates 3 facing the inner ends, and the two transverse parts of the second U-shaped plate 36 are contacted with the limit plates 34 facing the outer ends, and then the first U-shaped plate 35 and the second U-shaped plate 36 are connected to the corresponding L-shaped terminal plates 3;

[0061] At this time, the structure formed by the second U-shaped plate 36 and the limiting plate 34 is wrapped around the upper outer end of the bending position of the L-shaped terminal plate 3, and the first U-shaped plate 35 is wrapped around the lower outer end of the bending position of the L-shaped terminal plate 3, thereby strengthening the bending position of the installed L-shaped terminal plate 3, effectively reducing the probability of defects such as cracking and deformation of the L-shaped terminal plate 3, and effectively ensuring the use effect of the product.

[0062] Embodiment 4: Fig.16 and Fig.17As shown, during manufacturing, the spiral metal material is firstly put onto the outer end of the positioning column 6, and the metal material is fitted with the front end of the mounting plate 5. At this time, the metal material is located in the outer cylinder structure formed by the first arc plate 51 and the second arc plate 52. Then, the metal material is pressed to form the metal coil 4, and both ends of the metal coil 4 extend out of the lower side of the mounting plate 5. During the vertical pressing process of the metal coil 4, the positioning column 6 and the outer cylinder structure formed by the first arc plate 51 and the second arc plate 52 will position the pressed metal coil 4.

[0063] Then, the soft magnetic composite powder 101 is wrapped around the structure formed by the metal coil 4, the mounting plate 5 and other components, and the two ends of the metal coil 4 extend out of the lower side of the wrapped soft magnetic composite powder 101, and then a vertical cold pressing method is used for pressing, so that the soft magnetic composite powder 101, the metal coil 4, the mounting plate 5 and other components form a vertical integrated structure;

[0064] The two ends of the metal coil 4 are then bent to form L-shaped terminal boards 3 at both ends of the metal coil 4. At this time, the two L-shaped terminal boards 3 are attached to the lower end surface of the pressed soft magnetic composite powder 101, and then the surfaces of the two L-shaped terminal boards 3 are electroplated to form welding terminals connected to the pads of the circuit board, thereby improving the electrical reliability of the product and greatly reducing its size, which can effectively improve the space utilization of the circuit board.

[0065] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
