Description

Technical Field

[0001] This utility model relates to the field of inductance technology, and in particular to an inductor, an electrical device, and an electrical system. Background Technology

[0002] In related technologies, the inductor traces in inductors are routed outside the inductor housing. Therefore, after the inductor is packaged, the leads connecting the inductor and terminals are exposed on the outside of the inductor. This makes the leads susceptible to damage during manufacturing and assembly, thus affecting the stability and reliability of the inductor.

[0003] Therefore, improving the stability and reliability of inductors has become an urgent problem to be solved. Utility Model Content

[0004] This invention provides an inductor, an electrical device, and an electrical system to address how to improve the stability and reliability of inductors.

[0005] This utility model is implemented as follows: It provides an inductor, an electrical device, and an electrical system. An inductor includes: a main housing; a plurality of inductors disposed within the main housing; and a terminal block with a plurality of terminals, each terminal being conductively connected to an electronic wire. A wiring channel is formed between the inductors and the terminal block. The inductors are provided with leads conductively connected to them, and these leads are connected to the terminal block via the wiring channel. The inductors are conductively connected to the terminals via the leads and the electronic wires.

[0006] Furthermore, one end of the lead is connected to a single inductor, and the other end of the lead is sleeved on the electronic wire.

[0007] The number of terminals is multiple, and all of the terminals are disposed in the terminal holder. The terminal holder also includes a first insulating partition, and two adjacent terminals are separated by the first insulating partition.

[0008] Furthermore, the height of the wiring channel is 4mm to 15mm.

[0009] Furthermore, the electronic wire is surrounded by a protective shell.

[0010] Furthermore, along the extending direction of the main housing, limiting members are provided on both sides of the inductor, and the limiting members abut against the inductor.

[0027] The accompanying drawings provided in this application are schematic diagrams, and some elements are not shown in the drawings. The purpose is to clearly describe the technical solution and highlight the key features of the utility model. It is not intended to limit the technical solution to exclude these unshown elements. That is to say, the drawings are merely examples and do not represent a limitation on the specific form of the inductor 100.

[0028] like Figure 1 and Figure 2 As shown, the inductor 100 in this embodiment of the present invention includes: a main housing 10, a plurality of inductors 20, and a terminal block 30. The inductors 20 are disposed inside the main housing 10; the terminal block 30 is provided with a plurality of terminals 31, each terminal 31 being conductively connected to an electronic wire 70; a wiring channel 40 is formed between the inductors 20 and the terminal block 30, and the inductors 20 are provided with leads 50 that are conductively connected to the inductors 20. The leads 50 are connected to the terminal block 30 through the wiring channel 40, and the inductors 20 are conductively connected to the terminals 31 through the leads 50 and the electronic wires 70.

[0029] Thus, by forming a wiring channel 40 between the inductor 20 and the terminal block 30, the lead 50 of the inductor 20 can be routed and connected to the electronic wires within the wiring channel 40 in the main housing 10. This avoids the need for the lead 50 to be exposed on the external surface of the inductor 100 for routing. At the same time, after the inductor 100 is packaged, the electronic wires do not need to be exposed on the external surface of the inductor 100, avoiding external physical damage, environmental interference, and potential electrical fault risks caused by exposed electronic wires and lead 50, thereby improving the overall stability and reliability of the inductor 100.

[0030] Meanwhile, in the prior art, in order to protect the exposed leads 50 and electronic wires outside the inductor 100, it is often necessary to set an additional protective shell or external shielding material outside the leads 50 and electronic wires. In this embodiment of the present invention, since the electronic wires and leads 50 are hidden inside the main housing 10, no additional protective measures are needed. This not only simplifies the overall design structure of the inductor 100, but also reduces the production cost of the inductor 100.

[0031] Specifically, the inductor 100 of this invention includes a main housing 10. The main housing 10 is the outer frame of the inductor 100, and can be made of plastic, metal or composite material. It is used to protect the internal circuit components and connecting lines, and to provide mechanical support. The main housing 10 has sufficient space to accommodate the various circuit components.

[0032] Specifically, a plurality of inductors 20 are provided inside the main housing 10. The number of inductors 20 can be one or more. The inductors 20 can be wire-wound inductors 20, surface-mount inductors 20 or integrated inductors 20, and are not limited here.

[0033] Specifically, the terminal block 30 is provided with a plurality of terminals 31, which are electrical connection interfaces of the inductor 100. Each terminal 31 is used to connect to an external electronic wire 70 or circuit. The terminals 31 on the terminal block 30 are also electrically connected to the leads 50 of the inductor 20 to realize the conductive connection between the inductor 20 and the electronic wire 70 or external circuit.

[0034] Specifically, regarding the connection method between the lead 50 and the inductor 20, one end of each lead 50 is connected to a single inductor 20, and the other end of each lead 50 is sleeved on the electronic wire 70 to achieve a conductive connection between the inductor 20 and the electronic wire 70.

[0035] Specifically, the wiring channel 40 is located between the inductor 20 and the terminal block 30. The lead 50 connected to the inductor 20 can be connected to the electronic wire located on the terminal block 30 through the wiring channel 40. It is understood that the wiring channel 40, located between the inductor 20 and the terminal block 30, means that when the lead 50 is connected, it is not exposed outside the inductor 100, reducing external electromagnetic interference to the lead 50. Connecting the lead 50 to the electronic wire located on the terminal block 30 through the wiring channel 40 also helps with electrical isolation between the lead 50 and other external electrical components, preventing short circuits.

[0036] Meanwhile, the lead 50 connected to the inductor 20 can be connected to the electronic wires located on the terminal block 30 through the wiring channel 40, which can also prevent damage or scratches to the external structure of the lead 50. In addition, there is no need to install a protective sleeve on the outside of the lead 50 of the inductor 20, reducing the production cost of the inductor 100.

[0037] Understandably, in its natural state, the wiring channel 40 is located on the side of the inductor 20 facing away from the inner bottom wall of the main housing 10. Specifically, the terminal block 30 is located on the side of the inductor 20 facing away from the inner bottom wall of the main housing 10, and the wiring channel 40 is located between the inductor 20 and the terminal block 30. The wiring channel 40 inside the main housing 10 connects the lead 50 to the electronic wire of the terminal block 30, thus forming a natural isolation barrier between the lead 50 and external circuits or other electrical appliances. This isolation helps prevent short circuits caused by external electrical interference or improper wiring, ensuring the safe operation of the inductor 100.

[0038] Optionally, in one possible implementation, the height of the trace channel 40 is 1mm to 10mm. For example, it can be 1mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 8mm, or 10mm. In this way, sufficient trace space can be provided for the traces of the lead 50, while also avoiding an excessively large overall size of the inductor 100.

[0039] In one possible implementation, the lead 50 is located on the side of the inductor 20 facing the terminal block 30. In this way, the lead 50 of the inductor 20 is not exposed to the outside of the inductor 100, further preventing the lead 50 from being interfered with or damaged by external structures.

[0040] Specifically, the lead 50 is located within the wiring channel 40. The lead 50 of the inductor 20 is positioned towards the terminal block 30. Alternatively, in its natural state, the lead 50 is positioned above the inductor 20.

[0041] In one possible implementation, there can be multiple inductors 20, and within the wiring channel 40, the leads 50 of each inductor 20 are staggered relative to each other in the width direction of the main housing 10. This staggered arrangement of the electronic wires of each inductor 20 within the wiring channel 40 avoids electromagnetic interference between inductors 20 and reduces crosstalk. Simultaneously, the staggered arrangement of the leads 50 allows each inductor 20 to be routed along different paths, reducing electromagnetic coupling between the leads 50 of adjacent inductors 20, thereby improving the stability of the inductor 100.

[0042] In one possible implementation, there are multiple terminals 31, all disposed on a terminal block 30. The terminal block 30 also includes a first insulating partition 32, with adjacent terminals 31 separated by the first insulating partition 32. Thus, the first insulating partition 32 provides electrical isolation, preventing electrical short circuits or interference between adjacent terminals 31. The insulating partition between each terminal 31 effectively isolates current paths on different terminals 31, avoiding interference or unnecessary current crosstalk between different terminals 31, thereby improving the performance and stability of the inductor 100.

[0043] Meanwhile, the mechanical stability of the inductor 100 can also be enhanced by the provision of the first insulating partition 32. It can be understood that the partition not only ensures electrical isolation between the terminals 31, but also prevents the terminals 31 from changing position due to external vibration or impact, thus maintaining their stable connection.

[0044] Specifically, the first insulating partition 32 may include one or more of the following: PI (polyimide) insulating partition, PPS (polyphenylene sulfide) insulating partition, PC (polycarbonate) insulating partition, or PP (polypropylene) insulating partition.

[0045] Specifically, the first insulating partition 32 can be integrally formed with the terminal block 30, or the first insulating partition 32 can be separately formed from the terminal block 30, which is not limited here.

[0046] In one possible implementation, the electron wire is surrounded by a protective shell. This protects the electron wire and prevents it from being damaged.

[0047] Specifically, the protective shell surrounding the electronic wires is an insulating protective shell. This prevents the electronic wires from coming into contact with other electrical structures, which could lead to a short circuit.

[0048] In one possible implementation, limiting members 60 are provided on both sides of the inductor 20 along the extending direction of the main housing 10, and the limiting members 60 abut against the inductor 20. Thus, the limiting members 60 can fix the position of the inductor 20, preventing the inductor 20 from shifting or displacing within the main housing 10. Simultaneously, it can also improve the stability of the inductor 20; when the inductor 20 is subjected to external vibration or other physical disturbances, the limiting members 60 can effectively prevent changes in the position of the inductor 20.

[0049] Furthermore, the limiting member 60 directly abuts against both sides of the inductor 20, ensuring that the inductor 20 will not shift along the extension direction of the main housing 10. The limiting member 60 can firmly fix the inductor 20 while avoiding damage or excessive compression to the inductor 20.

[0050] Specifically, the limiting member 60 may include one or more of the following: PI (polyimide) limiting member 60, PPS (polyphenylene sulfide) limiting member 60, PC (polycarbonate) limiting member 60, or PP (polypropylene) limiting member 60.

[0051] Specifically, the limiting member 60 can be integrally formed with the main housing 10, or the limiting member 60 can be separately formed from the main housing 10, which is not limited here.

[0052] In one possible implementation, there are multiple inductors 20, and the main housing 10 includes multiple second insulating partitions 11 located between adjacent inductors 20. Thus, the second insulating partitions 11 provide electrical isolation between adjacent inductors 20, preventing short circuits or signal interference between them, thereby improving the electrical stability of the inductor 100. Simultaneously, by providing the second insulating partitions 11, electrical coupling between different inductors 20 can be effectively reduced, ensuring that the signal processing of each inductor 20 is not affected by other inductors 20.

[0053] It can be understood that the second insulating partition 11 can also enhance the mechanical structure of the main housing 10, making the fixation between the various inductors 20 more stable. The second insulating partition 11 can prevent the inductors 20 from being displaced or damaged due to vibration or external force during operation, thereby improving the mechanical stability of the inductor 100.

[0054] Specifically, the second insulating partition 11 may include one or more of the following: PI (polyimide) insulating partition, PPS (polyphenylene sulfide) insulating partition, PC (polycarbonate) insulating partition, or PP (polypropylene) insulating partition.

[0055] Specifically, the second insulating partition 11 can be integrally formed with the main housing 10, or the second insulating partition 11 can be separately formed from the main housing 10, which is not limited here.

[0056] Furthermore, the second insulating partition 11 can further position the inductor 20, facilitating its installation. Simultaneously, it effectively optimizes the internal spatial layout, making the spacing between the inductors 100 more reasonable and preventing electrical losses caused by excessively close spacing between the inductors 20.

[0057] like Figure 3 As shown, this embodiment of the utility model also provides an electrical device 1001, which includes the inductor 100 described above. Specifically, the electrical device 1001 can be a photovoltaic inverter, an energy storage converter, a power supply, a radio frequency device, an electrical control device, a lighting device, a communication device, a home appliance, a medical device, an automotive electronic device, an industrial automation device, a consumer electronic device, etc., and is not limited thereto.
