Description

Technical Field

[0001] This utility model relates to the field of surface mount inductor technology, specifically a combined surface mount inductor. Background Technology

[0002] When current flows through a coil, a magnetic field is induced within it. This induced magnetic field then generates an induced current that opposes the current flowing through the coil. This interaction between the current and the coil is called inductive reactance, and the device that provides inductance is called an inductor. An inductor is a component that can convert electrical energy into magnetic energy and store it.

[0003] Chinese patent CN221466386U discloses a combined surface-mount common-mode inductor, comprising a main body and a base. Two bottom frames are mounted on the upper end of the base, and two telescopic rods are fixed inside the bottom frames. Springs are mounted on the telescopic rods, and the upper ends of the telescopic rods are connected to a second limiting frame. A connecting plate is fitted inside the second limiting frame, and a crossbar is fixed between the two supporting plates. A connecting rod is fixed to the outside of the crossbar, and a coil is wound on the connecting rod. This invention, by fitting the two supporting plates into the second limiting frame in the base plate, utilizes the telescopic rods and springs to facilitate the engagement of the supporting plates, resulting in good stability, a simple structure, and convenient assembly and disassembly. This allows for more stable fixation of the supporting plates, crossbar, connecting rod, and coil inside the second limiting frame. Furthermore, the simple structure facilitates disassembly and assembly, simplifying future maintenance and parts replacement, thus saving costs.

[0004] However, the combined inductor disclosed in the above patent still has certain shortcomings in practical applications. It uses two support plates to be clamped inside the limiting frame two in the base plate and is covered with a stabilizing cover. However, this combination method occupies a large space and the internal space of the limiting frame two is limited, making it inconvenient to control the number of inductors and unable to combine and install more inductors, which is quite inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a modular surface mount inductor to solve the problems mentioned in the background art, such as the large space occupation of existing modular inductors, limited space making it inconvenient to control the number of inductors combined, and the inability to combine and install more inductors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined surface mount inductor, comprising a combination plate, wherein a mounting groove is formed on the top wall of the combination plate, an inductor is fixed in the cavity of the mounting groove, combination holes are formed on both sides of the top wall of the combination plate, and combination posts are fixedly installed on both sides of the bottom wall of the combination plate, the positions of the combination posts corresponding to the combination holes, positioning holes are formed on the surface of the post, and a positioning mechanism is provided on the circumferential side wall of the combination plate for combining two combination plates together.

[0007] Preferably, the positioning mechanism includes a positioning frame and a first bolt. The positioning frame is disposed on both sides of the combination plate, and the two positioning frames correspond to the combination holes on both sides respectively. The first bolt fixes the positioning frame to the combination plate.

[0008] Preferably, the positioning mechanism further includes a first through hole, a second through hole, and a positioning rod. The first through hole is formed on the circumferential side wall of the combination plate and communicates with the cavity of the combination hole. The second through hole is formed on the side wall of the positioning frame away from the combination plate. The first through hole and the second through hole are located on the same axis. One end of the positioning rod passes through the cavity of the second through hole, and the other end of the positioning rod passes through the cavity of the first through hole and is inserted into the cavity of the combination hole.

[0009] Preferably, the positioning mechanism further includes a pressing plate, a second bolt, a first threaded hole, and a second threaded hole. The first threaded hole is formed on the surface of the positioning rod, and the second threaded hole is formed on the plate of the pressing plate. The pressing plate is located in the frame of the positioning frame and is clamped on the rod of the positioning rod. The bolt of the second bolt fixes the pressing plate and the positioning rod together through the second threaded hole and the first threaded hole.

[0010] Preferably, the positioning mechanism further includes a lever and a spring. The lever is fixedly installed at the end of the positioning rod away from the combined hole. The spring is located in the frame of the positioning frame and sleeved on the surface of the positioning rod. The spring is located on the side of the extrusion plate away from the combined disc. The rod of the positioning rod is adapted to the cavity of the positioning hole.

[0011] Preferably, the mounting slot has multiple heat dissipation fins installed on both sides of the cavity, and the inductor's two sides abut against the heat dissipation fins on both sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention mounts inductors in mounting slots on a combination plate. Combination holes and combination posts are provided on the top and bottom walls of the combination plate, with positioning holes on the combination posts. This allows for stacking of inductors. During assembly, a lever on the bottom combination plate is pulled, causing two positioning rods to move. Since the extrusion plate is fixed to the positioning rods via a first threaded hole, a second threaded hole, and a second bolt, the movement of the positioning rods causes the extrusion plate to move along with it, compressing the spring. Once the positioning rods are withdrawn from the combination holes, the combination post of the top combination plate is inserted into the combination hole on the top wall of the bottom combination plate. Then, the lever is released, and the spring causes the extrusion plate to automatically reset the positioning rods, allowing them to automatically insert into the positioning holes. This completes the stacking assembly of the two combination plates. This stacking assembly method has a small lateral space requirement and is quick to install, facilitating the stacking of multiple combination plates carrying inductors. There is no limit to the number of combinations; they can be assembled according to actual needs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a combined surface mount inductor, including a combination plate 1, a mounting groove 2 formed on the top wall of the combination plate 1, an inductor 4 installed in the groove cavity of the mounting groove 2, two combination holes 5 respectively formed on the left and right top walls of the combination plate 1, two combination posts 17 respectively welded to the left and right bottom walls of the combination plate 1, the positions of the combination posts 17 and the combination holes 5 are corresponding, the purpose of which is to ensure that the combination posts 17 of the top combination plate 1 can be inserted into the combination holes 5 located on the top wall of the bottom combination plate 1, a positioning hole 18 formed on the surface of the post 17, and a positioning mechanism set on the circumferential side wall of the combination plate 1 for combining the two combination plates 1 together.

[0017] The positioning mechanism includes a positioning frame 6 and a first bolt 12. The positioning frames 6 are located on the left and right sides of the combination plate 1, and the two positioning frames 6 correspond to the combination holes 5 on both sides respectively. The first bolt 12 fixes the positioning frames 6 to the combination plate 1, which is to facilitate the disassembly of the positioning frames 6 from the combination plate 1 via the first bolt 12. The positioning mechanism also includes a first through hole 7, a second through hole 8, and a positioning rod 10. The first through hole 7 is opened on the circumferential side wall of the combination plate 1 and is connected to the cavity of the combination hole 5. The second through hole 8 is opened on the positioning frame 6 away from the combination plate 1. On one side wall, the first through hole 7 and the second through hole 8 are located on the same axis. One end of the positioning rod 10 passes through the cavity of the second through hole 8, and the other end of the positioning rod 10 passes through the cavity of the first through hole 7 and is inserted into the cavity of the combination hole 5. The positioning mechanism also includes a pressing plate 13, a second bolt 14, a first threaded hole 15, and a second threaded hole 16. The first threaded hole 15 is opened on the surface of the positioning rod 10, and the second threaded hole 16 is opened on the plate of the pressing plate 13. The pressing plate 13 is located in the frame of the positioning frame 6, and the pressing plate 13... The second bolt 14, secured to the positioning rod 10, uses its bolt body to fix the extrusion plate 13 to the positioning rod 10 via the second threaded hole 16 and the first threaded hole 15. This allows the extrusion plate 13 to be removed from the positioning rod 10. The positioning mechanism also includes a lever 9 and a spring 11. The lever 9 is welded to the end of the positioning rod 10 away from the assembly hole 5, facilitating movement of the positioning rod 10 via the lever 9. The spring 11 is located within the frame of the positioning bracket 6 and is fitted onto the surface of the positioning rod 10. The 1 is located on the side of the extrusion plate 13 away from the combination plate 1. Its purpose is to enable the positioning rod 10 to be automatically reset. The rod body of the positioning rod 10 is adapted to the cavity of the positioning hole 18. Its purpose is to enable the positioning rod 10 to be inserted into the positioning hole 18. Multiple heat dissipation fins 3 are installed on both sides of the cavity of the mounting groove 2. The two sides of the inductor 4 abut against the heat dissipation fins 3 on both sides. Its purpose is to dissipate the heat generated by the inductor 4 during operation through the heat dissipation fins 3, so as to prevent it from being in a high-temperature operating state for a long time.

[0018] Working principle: By installing the inductor 4 in the mounting slot 2 on the combination plate 1, and by setting combination holes 5 and combination posts 17 on the top and bottom walls of the combination plate 1 respectively, and setting positioning holes 18 on the combination posts 17, the inductors 4 can be stacked vertically when they need to be combined. When combining, first pull the lever 9 on the bottom of the combination plate 1 to move the two positioning rods 10. Since the extrusion plate 13 is fixed to the positioning rods 10 through the first threaded hole 15, the second threaded hole 16 and the second bolt 14, the movement of the positioning rods 10 drives the extrusion plate 13 to move together, and the extrusion plate 13 moves along with the positioning rods 10. 3. When the spring 11 is squeezed and the positioning rod 10 is pulled out from the combination hole 5, the combination post 17 of the top combination plate 1 is inserted into the combination hole 5 on the top wall of the bottom combination plate 1. Then the lever 9 is released, and under the action of the spring 11, the squeezing plate 13 drives the positioning rod 10 to automatically reset, so that the positioning rod 10 is automatically inserted into the positioning hole 18, thereby completing the stacking combination between the two combination plates 1. This stacking combination method has a small lateral space occupation rate and is a quick way to install and combine. It is convenient to stack multiple combination plates 1 carrying inductors 4, and there is no limit to the number of combinations. It can be combined according to actual needs.
