Description

Technical Field

[0001] This utility model relates to the field of common mode inductor technology, and in particular to a common mode inductor packaging structure with high magnetic shielding. Background Technology

[0002] With the increasing integration and miniaturization of electronic devices, the performance requirements for electronic components are becoming increasingly stringent. Common-mode inductors, as a commonly used anti-interference component, are widely used in various electronic devices to suppress common-mode interference signals and improve circuit stability and reliability.

[0003] The high-magnetic-shielded common-mode inductor package structure mainly consists of inductor elements, copper wires, a shielding layer, and pins. When the common-mode inductor is connected to a circuit, the winding generates a magnetic field through current, and the magnetic core guides the magnetic field to form an efficient magnetic circuit. The shielding layer prevents the internal magnetic field from leaking out and interfering with surrounding components, while also isolating the external magnetic field from affecting the internal winding and magnetic core. Fixed pins ensure stable transmission of electrical signals, while the sealant layer and insulation layer ensure long-term stable operation of the entire structure in complex environments, ultimately achieving the efficient anti-interference function of the common-mode inductor in environments with strong electromagnetic interference.

[0004] In the prior art, some high magnetic shielding common mode inductor packaging structures cannot be quickly disassembled and installed when equipment parts need to be replaced, making equipment maintenance complex and inefficient. To address this issue, a high magnetic shielding common mode inductor packaging structure is proposed. Utility Model Content

Together with the shielding layer inside the seat ring, it achieves shielding of the components, improves the working life of the equipment, and solves the problems of poor heat dissipation and poor shielding of the equipment.

Connecting post a9 serves a connecting function. Each connecting post a9 has a button 11 fixedly connected to its exterior. The button 11 is a manually operated trigger component. A connecting plate b8 is fixedly connected to the outer side of the connecting post a9, serving a connecting, fixing, and limiting function. A spring 10 is sleeved on the outside of the connecting post a9. The spring 10 provides elastic force and is often used to reset the position of the component. The outer side of each spring 10 is fixedly connected to the side of the button 11. Two locking blocks 6 are slidably connected inside the cylindrical retainer 12. A connecting plate a7 is fixedly connected to the outer side of the locking block 6, serving a connecting function. The bottom of each connecting plate a7 is slidably connected inside the retainer 5. A connecting post b13 is fixedly connected to the outside of the cylindrical retainer 12, serving a supporting connection function. A rotating component is provided on the outer right side of the connecting post b13.

[0034] The rotating assembly includes a positioning block 15, which is fixed to a limiting block 14. The bottom of the positioning block 15 is fixedly connected to the top of the shielded heat-conducting base 1. The top of the positioning block 15 is fixedly connected to two limiting blocks 14, which are components that restrict the movement of the bearing 21. The bearing 21 is rotatably connected inside the two limiting blocks 14. The bearing 21 rotates flexibly while supporting its radial direction. The bearing 21 is fixedly connected to the outside right side of the connecting column b13. The top of the connecting plate b8 is fixedly connected to the inside top side of the cylindrical retainer 12. The button 11 is slidably connected to the outside of the cylindrical retainer 12. The top of the shielded heat-conducting base 1 is fixedly connected to a seat ring 2, which is usually used for sealing between components. The external side of the locking block 6 is slidably connected to the inside of the retainer 5. The locking block 6 is a component that corresponds to the groove to prevent accidental dislodgement.

[0035] Reference Figure 4 and Figure 5 The shielded thermally conductive base 1 has a heat dissipation assembly inside, which includes a heat-conducting plate 16. The heat-conducting plate 16 is used to expand the heat dissipation area and transfer heat. The left side of the heat-conducting plate 16 is fixedly connected to the inner top side of the shielded thermally conductive base 1. The right side of the heat-conducting plate 16 is fixedly connected to multiple heat-conducting aluminum blocks 19, which serve as heat dissipation mediums. The right side of the heat-conducting plate 16 is fixedly connected to a connecting block 20, which is used to connect two different components. The top of the connecting block 20 is fixedly connected to the bottom of the inductor 18, which is the core component of the electronic component.

The outer side of the inductor 18 is fitted with two copper wires 17, which are highly conductive copper wires.

[0036] Working principle: First, the inductor 18 with two connecting blocks 20, along with the copper wire 17, is placed on the heat-conducting plate 16 in the shielded heat-conducting base 1. Then, the shielding layer 4, along with the card holder 5, is placed inside the seat ring 2 and fixed on the connecting plate 20 outside the inductor 18 to prevent the inductor 18 from deviating from its position in the shielded heat-conducting base 1. By rotating the connecting column b13, the two card blocks 6 inside the cylindrical card case 12 are locked into the card slots inside the card holder 5, thus completing the fixation of the inductor 18 and achieving high magnetic shielding. When it is necessary to replace the inductor 18, press the buttons 11 on both sides of the cylindrical housing 12 to make the connecting post a9 move towards the connecting plate a7. The locking block 6 moves into the cylindrical housing 12 along with the connecting plate a7 until it is completely separated from the locking seat 5. At this time, rotate the connecting post b13 to make the cylindrical housing 12 separate from the locking seat 5, and the inductor 18 can be taken out together with the shielding layer 4. At the same time, the spring 10 and the connecting plate b8 make the components reset more convenient. Replacing the components allows the equipment to continue working more quickly, improving the working efficiency and replacement convenience of the equipment.

[0037] When the equipment is working, the inductor 18 and copper wire 17 in the shielded heat-conducting base 1 continuously release heat. The heat is quickly transferred to the shielded heat-conducting base 1 through the connecting block, the heat-conducting plate 16 and multiple heat-conducting aluminum blocks 19, achieving rapid heat dissipation and together with the shielding layer 4 in the seat ring 2, achieving shielding of the components and improving the service life of the equipment.
