Abstract
Description
Technical Field
[0001] This utility model relates to the field of inductor technology, and in particular to a sealed filter inductor. Background Technology
[0002] A filter inductor is an electronic component mainly used to remove high-frequency noise and spurious signals from circuits, making the signals in the circuit purer and more stable. By inserting an inductor into the circuit, the filtering purpose is achieved by utilizing the impedance characteristics of the inductor to the current.
[0003] Traditional filter inductors consist of a frame, capacitor, and coil. However, due to the lack of external protection, the capacitor and coil are exposed, making them prone to loosening or damage due to external forces such as collisions during use. Furthermore, external dust easily adheres to the surface of the coil, which can negatively impact the performance of the filter inductor.
[0004] Therefore, this patent provides a sealed filter inductor. Utility Model Content
[0005] To overcome the shortcomings of traditional filter inductors, such as lack of external protection, exposed capacitors and coils, easy loosening or damage due to external forces such as collisions, and easy adhesion of external dust to the coil surface, which affects the use of filter inductors, this utility model provides a sealed filter inductor.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: a sealed filter inductor comprising a housing, an inductor body, a heat conductor, and heat sinks. A sealing plate is provided at the opening of the housing, forming a closed space with the sealing plate. The inductor body is located inside the housing, comprising a capacitor and a coil. The capacitor is installed inside the housing, and the coil is wound around the outer surface of the capacitor. The leads at both ends of the coil extend through the sealing plate to provide connection to external devices. A heat conductor is embedded in the middle of the housing, and several heat sinks are provided on the outer surface of the housing.
[0007] Furthermore, the sealing plate is engaged with the outer casing.
[0008] Furthermore, it also includes a fixed rod, a rotating shaft, a protective shell, and a magnet. The fixed rods are fixedly connected to the sealing plate in a symmetrical arrangement. A rotating shaft is rotatably mounted on the fixed rod. A protective shell is fixedly connected to the rotating shaft. Magnets are embedded in the sides of the two protective shells that are in contact with each other.
[0009] Furthermore, it also includes a fixing block, a rotating rod, a torsion spring, and an anti-bend sleeve. The fixing block is fixedly attached to the sealing plate in a staggered arrangement. The rotating rod is rotatably mounted on the fixing block. The torsion spring that resets the rotating rod is sleeved on the fixing block. An anti-bend sleeve is provided at one end of the rotating rod near the coil pin. The sealing plate is fixedly attached with the same anti-bend sleeve. The anti-bend sleeve can clamp and protect the coil pin.
[0010] Furthermore, the anti-folding sleeve is provided with heat dissipation grooves.
[0011] Furthermore, a heat insulation layer is provided on the surface of the sealing plate.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a shell outside the filter inductor, the capacitor and coil are protected, which can effectively prevent the capacitor and coil from becoming loose or damaged due to external forces. At the same time, the shell is sealed by a sealing plate to prevent external dust from entering.
[0013] 2. By installing a heat conductor and heat sink on the casing, the heat on the filter inductor is conducted outward and dissipated, solving the heat dissipation problem of the inductor body under sealed conditions.
[0014] 3. Protect the exposed coil leads by clamping them with anti-bending sleeves to prevent them from being bent, pulled, or worn. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Example 1
[0024] Please see Figures 1-3 A hermetically sealed filter inductor includes a housing 1, an inductor body, a heat conductor 5, and heat sinks 6. A sealing plate 2 is provided at the opening of the housing 1. The sealing plate 2 is snap-fitted to the housing 1 and is detachable. The sealing plate 2 and the housing 1 can be combined to form a closed space, with the inductor body located inside the housing 1. The housing 1 protects the inductor body. The inductor body includes a capacitor 3 and a coil 4. The capacitor 3 is installed inside the housing 1, and the coil 4 is wound around the outer surface of the capacitor 3. The leads at both ends of the coil 4 extend through the sealing plate 2 to provide connection to external devices. The heat conductor 5 is embedded in the middle of the housing 1, and several heat sinks 6 are provided on the outer surface of the housing 1. The heat sinks are evenly distributed around the heat conductor 5. The heat conductor 5 and the heat sinks 6 are used to dissipate heat from the inductor body. A heat insulation layer 15 is provided on the surface of the sealing plate 2 to enhance the heat insulation performance of the sealing plate 2 and prevent heat from the housing 1 from dissipating to the leads of the coil 4.
[0025] The outer casing 1 is installed on the outside of the inductor body to protect the capacitor 3 and the coil 4. This effectively prevents the capacitor 3 and the coil 4 from becoming loose or damaged due to external forces. At the same time, the sealing plate 2 seals the outer casing 1 to prevent external dust from entering. During the operation of the inductor body, the heat conductor 5 conducts heat out and then dissipates it to the outside through the heat sink 6, thus solving the heat dissipation problem of the inductor body under sealed conditions.

[0027] Based on Example 1, please refer to Figure 4 and Figure 5It also includes a fixing rod 9, a rotating shaft 8, a protective shell 7, and a magnet 10. The sealing plate 2 is fixedly connected to the fixing rod 9, which is symmetrically distributed vertically. The rotating shaft 8 is rotatably mounted on the fixing rod 9. The protective shell 7 is fixedly mounted on the rotating shaft 8. The protective shell 7 is used to protect the exposed coil 4 pins. The two protective shells 7 are embedded with magnets 10 on the side where they contact each other, and the two protective shells 7 are attracted and fixed by the magnets 10.
[0028] Please see Figure 5 and Figure 6 It also includes a fixing block 11, a rotating rod 12, a torsion spring 13, and an anti-bending sleeve 14. The fixing block 11 is fixedly connected to the sealing plate 2 and arranged vertically and staggeredly. The rotating rod 12 is rotatably mounted on the fixing block 11. The torsion spring 13 is sleeved on the fixing block 11 to reset the rotating rod 12. The two ends of the torsion spring 13 are respectively connected to the fixing block 11 and the rotating rod 12. An anti-bending sleeve 14 is provided at one end of the rotating rod 12 near the coil 4 pin. The sealing plate 2 is fixedly connected to the same anti-bending sleeve 14. The anti-bending sleeve 14 can clamp and protect the coil 4 pin to prevent the coil 4 pin from being bent, pulled, or worn. By rotating the rotating rod 12, one side of the anti-bending sleeve 14 can be removed to facilitate subsequent maintenance and repair of the coil 4 pin. In addition, the anti-bending sleeve 14 is provided with heat dissipation grooves to dissipate heat from the coil 4 pin.
