Description

Technical Field

[0001] This utility model relates to the field of inductor technology, specifically to a series integrated inductor device. Background Technology

[0002] Currently, inductors are core components in electronic circuits for storing and filtering electrical energy, and their performance directly affects the stability and energy efficiency of electronic devices.

[0003] However, in existing technologies, traditional inductors mostly adopt a split magnetic core and winding structure, resulting in a large overall size and low heat dissipation efficiency, making it difficult to meet the requirements of high-density circuit design. The connection between the coil and conductive components mostly relies on welding or a single elastic contact. Long-term use can easily lead to increased contact resistance due to oxidation and vibration, causing overheating or signal distortion. Components are mostly fixed by screws or welding, resulting in low assembly efficiency and difficulty in disassembly and replacement, increasing later maintenance costs. The open magnetic circuit design is susceptible to interference from external magnetic fields, and the lack of effective shielding between the magnetic core and the circuit affects the accuracy of signal transmission.

[0004] Therefore, it is necessary to propose a series integrated inductor device. Utility Model Content

The base plate 200 is located directly below the magnetic column 100. Side plates 201 are fixedly connected to both ends of the base plate 200.

A snap-fit ​​groove 204 is formed on the outer surface of the side plate 201. Two snap-fit ​​strips 401 are fixedly connected to the two side edges of the connecting plate 400. The connecting plate 400 is located inside the snap-fit ​​groove 204, and one of the snap-fit ​​strips 401 snaps into the groove wall of the snap-fit ​​groove 204. Electromagnetic induction is achieved by winding a coil 104 around the surface of the magnetic column 100, and the insulating plates 101 at both ends can effectively isolate the current path; the support frame formed by the base plate 200 and the side plate 201 can improve the structural stability of the device, the lateral layout of the skeleton 202 optimizes the space utilization, and the matching structure of the snap-fit ​​groove 204 and the snap-fit ​​strip 401 facilitates modular assembly.

The groove 102 on the side of the insulating plate 101 and the inner strip 203 on the inner wall of the side plate 201 form an engaging positioning structure, which can enhance the assembly accuracy of the magnetic column 100 and the base plate 200, prevent axial displacement between components, and reduce the impact of external vibration on the connection parts.

[0028] In a further preferred embodiment, a second metal conductive block 402 is embedded in the top of the connecting plate 400. A second metal elastic arc plate 403 is fixedly connected to both sides of the second metal conductive block 402. A through groove 404 is formed at the top of the second metal conductive block 402, passing through both the second metal conductive block 402 and the connecting plate 400. The second metal conductive block 402 at the top of the connecting plate 400, in conjunction with the second metal elastic arc plate 403, achieves elastic conductive contact. The through structure of the groove 404 facilitates the routing of wires from the end of the coil 104, while the deformation characteristics of the second metal elastic arc plate 403 buffer the mechanical stress at the connection point.

The groove 103 on the top of the insulating plate 101 and the metal conductive block 402 form a cooperative guiding structure to ensure precise docking of the end of the coil 104. The double-layer elastic contact design of the metal elastic arc plate 302 and the metal elastic arc plate 403 can eliminate the problem of poor contact caused by oxidation of the contact surface.

[0031] In a further preferred embodiment, a conductive metal sheet 303 is detachably inserted into the interior of the second wire trough 301. The top end of the conductive metal sheet 303 abuts against the first metal elastic arc plate 302, and the bottom end of the conductive metal sheet 303 is tightly fitted to the second metal elastic arc plate 403. The detachable conductive metal sheet 303 inside the second wire trough 301 forms a two-stage conductive path, with its upper and lower ends tightly fitted to the first metal elastic arc plate 302 and the second metal elastic arc plate 403, respectively. This ensures continuity of conductivity while allowing for individual replacement and maintenance of conductive components, thus improving the scalability of the device.
