Description

Technical Field

[0001] This utility model relates to the field of inductors, and more particularly to high-current anti-interference T-core inductors. Background Technology

[0002] In electronic devices and communication systems, interference immunity is a crucial factor in ensuring system stability and reliability. With the rapid development of electronic technology, the operating frequencies of various electronic devices and communication systems are increasing, leading to ever-growing demands for circuit interference immunity. Traditional inductor designs exhibit lower-than-expected performance in high-frequency applications, especially in environments with strong electromagnetic interference. Traditional inductors often fail to meet the required interference immunity, resulting in decreased system reliability and negatively impacting user experience.

[0003] There is currently a Chinese patent application (CN202123107495.2) for an inductor that can improve tensile strength. The inductor includes a substrate, a T-shaped core, and a flat coil. The substrate is formed by pressing magnetic powder and covers the outside of the T-shaped core and the flat coil. The T-shaped core includes a base plate and a cylindrical protrusion. The flat coil is wound on the cylindrical protrusion. The base plate has a notch at each of its four corners. Each notch has an angle A that slopes upwards towards the solid side at the bend of the flat coil, thus effectively increasing the pull-out reaction force when the bend passes through that point. This solution effectively increases the pull-out reaction force while avoiding the risk of short circuits.

[0004] However, the above-mentioned patent has certain defects in use. Since the inductor only contacts the iron core through the substrate during actual operation, it is prone to electromagnetic interference during long-term operation, which affects the inductor performance. In addition, due to the limited contact area between the substrate and the iron core during installation, the installation requires high precision and is prone to installation errors.

[0005] To address these issues, a high-current anti-interference T-core inductor is proposed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, such as limited contact area between the substrate and the iron core, high precision requirements during installation, and easy installation errors, this utility model provides a high-current anti-interference T-core inductor.

[0007] This utility model is achieved using the following technical solution:

[0008] The high-current anti-interference T-core inductor includes a base, a base platform on the top of the base, a coil wound on the base platform, a base shell tightly attached to the outer wall of the base platform, the coil being wrapped inside the base shell, and multiple pins branching off at the end of the coil; mounting ports are provided around the base, including a first socket and a second socket;

[0009] The base is located at the bottom of the base, and the top of the base is provided with a plurality of first plug blocks that are adapted to the first plug.

[0010] The shielding shell is fitted over the base shell, and the bottom of the shielding shell is provided with a plurality of second plug blocks that are adapted to the second plug.

[0011] As a preferred embodiment of this utility model, the base is symmetrically provided with reserved areas, the number of mounting ports is the same as the number of pins, the front end of the pins passes through the mounting ports and extends into the reserved areas, and the pins located in the reserved areas are welded with electrodes.

[0012] As a preferred embodiment of this utility model, the second socket is provided with symmetrical grooves on both sides, and the second plug is provided with symmetrical sliders on both sides. The sliders cooperate with the grooves, and the sliders and grooves are assembled together.

[0013] As a preferred embodiment of the present invention, a filler is provided at the bottom of the groove, and the filler is in close contact with the bottom of the groove and in contact with the slider.

[0014] In a preferred embodiment of this utility model, a connecting member is provided on the outer peripheral wall of the shielding shell and the base, and the connecting member is in close contact with the outer peripheral wall of the shielding shell and the base. The connecting member is specifically a welding rod.

[0015] As a preferred embodiment of this utility model, the base and the platform are in a T-shape.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. By providing a shielding shell on the base and installing a base at the bottom of the base, the shielding shell is installed by inserting the second plug into the second socket when the second plug is installed, and the base is installed by inserting the first plug into the first socket when the first plug is installed. This makes installation convenient, improves the overall structural stability, and the shielding shell effectively reduces electromagnetic interference.

[0018] 2. When installing the shielding shell, when the second insert is inserted into the corresponding second socket, the sliders on both sides of the second insert are inserted into the grooves on both sides of the second socket. The sliders slide along the grooves until they are fully embedded. When the sliders slide into place in the grooves, the filler fits tightly. After subsequent hot pressing, the filler melts and firmly fixes the sliders and grooves, ensuring that the shielding shell and the base shell are tightly bonded.

[0019] 3. Set the coil at the end of the coil and branch multiple pins. The pins extend to the reserved area through the mounting port. The electrode is soldered to the front end of the pin to ensure stable current transmission and improve the overall anti-interference performance. Attached Figure Description

[0033] In this embodiment, the base 4 is the bottom shell of the entire device. The base 4 is installed by inserting from bottom to top. The top of the base 4 is provided with a first insertion block 41. The number of first insertion blocks 41 corresponds to the number of first sockets 21. The first insertion blocks 41 and the first sockets 21 are an assembly structure. When the base 4 needs to be installed, the first insertion blocks 41 are aligned with the first sockets 21 and inserted to complete the pre-positioning installation.

[0034] The shielding shell 3 is fitted outside the base shell 12, and the bottom of the shielding shell 3 is provided with a plurality of second plug blocks 31 that are adapted to the second plug 22.

[0035] In this embodiment, the shielding shell 3 serves as the outer protective shell of the entire device, playing a role in shielding electromagnetic interference. The shielding shell 3 is installed by fitting it from top to bottom. The shielding shell 3 has an inward opening in the middle. After the shielding shell 3 is installed, it is tightly attached to the outer surface of the base shell 12 and then hot-pressed. The bottom of the shielding shell 3 is provided with a second insert 31. The number of second inserts 31 corresponds to the number of second sockets 22, and the second inserts 31 and the second sockets 22 are assembled. When the shielding shell 3 needs to be installed, the second inserts 31 are aligned with the second sockets 22 and inserted to ensure that the shielding shell 3 and the base shell 12 fit tightly together to achieve the best shielding effect.

[0036] Specifically, the base 4 is symmetrically provided with a reserved area 42, the number of mounting ports 2 is the same as the number of pins 51, the front end of the pin 51 passes through the mounting port 2 and extends into the reserved area 42, and the pin 51 located in the reserved area 42 is welded with an electrode 52.

[0037] In this embodiment, the base 4 has a reserved area 42, which is symmetrically distributed. The number of pins 51 is the same as the number of mounting ports 2. During installation, the coil 5 is wound on the base 11. Multiple pins 51 first extend into the mounting port 2, and then extend into the reserved area 42. Then the base 4 is fitted on. Electrodes 52 are welded to the pins 51 in the reserved area 42. The electrodes 52 are firmly connected to the pins 51 to ensure stable current transmission.

[0038] Specifically, the second insertion port 22 is symmetrically provided with sliding grooves 23 on both sides, and the second insertion block 31 is symmetrically provided with sliders 32 on both sides.

The sliders 32 and the sliding grooves 23 cooperate with each other. When installing the shielding shell 3, in order to ensure stable installation, in addition to inserting the second plug 31 into the second socket 22, sliders 32 and sliding grooves 23 are also provided. During installation, after the second plug 31 is inserted into the second socket 22, the sliders 32 slide along the sliding grooves 23 to further lock the position and ensure that the shielding shell 3 and the base shell 12 are tightly connected to prevent loosening.

[0040] Specifically, a filler 24 is provided at the bottom of the groove 23, and the filler 24 is in close contact with the bottom of the groove 23 and the slider 32.

[0041] In this embodiment, a filler 24 is provided at the bottom of the slide groove 23. The function of the filler 24 is to fill the gap between the slide groove 23 and the slider 32 after hot pressing. After the slider 32 slides along the slide groove 23 to the predetermined position, the filler 24 expands due to heat, fills the gap, and enhances the structural stability.

[0042] Specifically, the shielding shell 3 and the base 1 are provided with connecting parts on their outer peripheral walls, and the connecting parts are in close contact with the outer peripheral walls of the shielding shell 3 and the base 1. The connecting parts are specifically welding rods 6.
