Description

Technical Field

[0001] This application relates to the field of filter technology, and more particularly to a filter and electronic device. Background Technology

[0002] In electronic devices, the threaded connection assembly that connects the filter to the device body may become loose due to external forces such as vibration and impact. Therefore, it is necessary to take measures to prevent loosening of the connection between the filter and the device body.

[0003] Related technologies typically involve placing an elastic washer between the bolt head and the equipment body of the threaded connection assembly. The elastic washer provides a preload to achieve frictional anti-loosening between the bolt head and the equipment body.

[0004] However, under long-term external force, the elastic washer material will undergo elastic fatigue, which will weaken or even disappear the preload it provides, thus causing it to lose its anti-loosening function. Utility Model Content

[0005] This application provides a filter and an electronic device. The filter has a first anti-loosening member, and the probability of the first anti-loosening member failing to loosen is lower than that of the elastic washer. This can ensure the stability of the connection between the filter and the device body, thereby ensuring the reliability of the filter operation.

[0006] In a first aspect, embodiments of this application provide a filter, including:

[0007] Filter body;

[0008] A connector is fixedly connected to the filter body, and the connector has a limiting part.

[0009] Threaded fasteners;

[0010] The first anti-loosening component includes a first component, at least one second component, and at least one third component. The second and third components are both connected to the first component. The first component is located on the end face of the connecting seat. The threaded connector is used to be threadedly connected to the device body of the electronic device in sequence via the first component and the connecting seat.

[0011] The second component is connected to the limiting part so that the connecting seat restricts the rotation of the second component relative to the connecting seat; the third component abuts against the first side of the head of the threaded connector to restrict the rotation of the threaded connector relative to the connecting seat.

[0012] In some possible implementations, the connector has a first connecting hole, the first component has a second connecting hole, and the threaded connector is threadedly connected to the device body via the first connecting hole and the second connecting hole in sequence.

[0013] In some possible implementations, the limiting part is the side of the connecting seat, and the second component has a second side that abuts against the limiting part.

[0014] In some possible implementations, there are at least two limiting parts and at least two second components, with each second side abutting against each limiting part.

[0015] In some possible implementations, the limiting part is a first groove formed on the connecting seat, and at least a portion of the second component is inserted into the first groove.

[0016] In some possible implementations, the threaded connector includes a head and a rod arranged sequentially, the rod being threaded to the device body via the first component and the connector seat in sequence.

[0017] In some possible implementations, the threaded fastener is an external hexagonal bolt.

[0018] In some possible implementations, there are at least two first sides, and the third component has at least two third sides, with each third side corresponding to and abutting against each of the first sides.

[0019] In some possible implementations, the forward projection of the second component toward the connector is located within the connector.

[0020] In some possible implementations, the side of the connector facing away from the first component has a second groove, which communicates with the first connecting hole;

[0021] The filter also includes a second anti-loosening element, which is disposed in the second groove. The second anti-loosening element has a threaded connection hole, and the threaded connection element is threadedly connected to the second anti-loosening element through the second connection hole, the first connection hole and the threaded connection hole in sequence.

[0022] In some possible implementations, the second locking element is a nylon nut.

[0023] In some possible implementations, the filter also includes a wiring assembly, which includes a terminal and a first fastener, a first wedge washer, a second wedge washer, and a second fastener that are sequentially threaded onto the terminal. The terminal is fixedly connected to the filter body, and the terminal, the first fastener, the first wedge washer, the second wedge washer, and the second fastener are all conductive components.

[0024] The first fastener and the first wedge washer are used together to clamp the cable, or the second fastener and the first wedge washer are used together to clamp the cable.

[0025] In some possible implementations, the filter also includes an elastic washer disposed between the filter body and the first fastener.

[0026] In some possible implementations, the filter body includes:

[0027] A heat-conducting housing, the heat-conducting housing having a receiving cavity;

[0028] A heat-conducting inner shell is disposed inside a heat-conducting outer shell. The heat-conducting inner shell divides the receiving cavity into a first sub-cavity and a second sub-cavity. The first sub-cavity is located between the heat-conducting outer shell and the heat-conducting inner shell, and the second sub-cavity is located inside the heat-conducting inner shell.

[0029] Heating element, located within the second sub-cavity;

[0030] The heat-conducting housing has at least one first vent and at least one second vent, both of which connect the first sub-cavity to the outside of the heat-conducting housing, with the second vent located above the first vent.

[0031] The heat-conducting inner shell has at least one third vent and at least one fourth vent, both of which connect the first sub-cavity and the second sub-cavity, with the fourth vent located above the third vent.

[0032] The thermal conductivity of the inner heat-conducting shell is greater than that of the outer heat-conducting shell.

[0033] In some possible implementations, the filter also includes a liquid cooling heat dissipation assembly, which includes a heat-conducting element and a liquid cooling pipe. The heat-conducting element has a channel, and the liquid cooling pipe is located within the channel and is used to house the coolant.

[0034] Secondly, embodiments of this application provide an electronic device, including a device body and any of the filters provided in the first aspect connected to the device body.

[0035] The filter and electronic device provided in this application embodiment have a second component connected to a limiting part. When the filter is subjected to external forces such as vibration or impact, the connecting seat can restrict the rotation of the second component relative to the connecting seat. Since both the second and third components are connected to the first component, the connecting seat can restrict the rotation of the third component relative to the connecting seat. Based on this, by abutting the third component against the first side of the head of the threaded connector, the third component can restrict the rotation of the threaded connector relative to the connecting seat, thereby achieving anti-loosening of the threaded connector.

[0036] In this embodiment, mechanical anti-loosening is achieved by setting a first anti-loosening component. Compared with the frictional anti-loosening achieved by using the elastic deformation of elastic washers in related technologies, as long as the first anti-loosening component does not break, it can maintain its anti-loosening function. The probability of anti-loosening failure is lower than that of elastic washers, which can ensure the stability of the connection between the filter and the device body, thereby ensuring the reliability of the filter operation.

Where there is no conflict, embodiments of this application and the various features thereof can be combined with each other, all of which are within the scope of protection of this application.

[0060] The electronic devices provided in this application can be applied to the photovoltaic, automotive electronics, industrial, medical equipment, and communication fields. Specifically, in the photovoltaic field, the electronic devices can be inverters, combiner boxes, energy storage devices, etc. In the automotive electronics field, the electronic devices can be in-vehicle entertainment devices, in-vehicle network devices, and driver assistance devices, etc. In the industrial field, the electronic devices can be data acquisition devices, main control devices, etc. In the medical field, the electronic devices can be electrocardiographs, magnetic resonance imaging (MRI) machines, etc. In the communication field, the electronic devices can be wireless equipment, fiber optic communication equipment, satellite communication equipment, etc. This application uses electronic devices in the photovoltaic field as an example for illustration.

[0061] Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0062] like Figure 1 As shown, the electronic device includes a device body 10 and a filter 20. The filter 20 is fixedly connected to the device body 10. The filter 20 can be used for power filtering, and / or signal filtering, and / or suppression of electromagnetic interference (EMI), etc.

[0063] In some embodiments, such as Figure 1As shown, the device body 10 may include a housing 11 and multiple electronic components 12. The filter 20 and the multiple electronic components 12 can be fixedly connected to the inner surface of the housing 11, and the housing 11 provides protection for the filter 20 and the electronic components 12. The filter 20 can be fixedly connected to the inner surface of the housing 11 by means of snap-fit, welding, screwing, etc. The electronic components 12 can be fixedly connected to the inner surface of the housing 11 by means of snap-fit, welding, screwing, etc.

[0064] Of course, in addition to being fixedly connected to the inner surface of the housing 11, in some embodiments, the filter 20 can also be fixedly connected to the outer surface of the housing 11. Alternatively, in some embodiments, a receiving groove is provided on the wall of the housing 11, and the filter 20 is located in the receiving groove and fixedly connected to the housing 11.

[0065] Of course, in addition to being fixedly connected to the inner surface of the housing 11, in some embodiments, the electronic device 12 can also be fixedly connected to the outer surface of the housing 11. Alternatively, in some embodiments, a receiving groove is provided on the wall of the housing 11, and the electronic device 12 is located in the receiving groove and fixedly connected to the housing 11.

[0066] In some embodiments, the device body 10 may further include a circuit board. The circuit board may be electrically connected to the various electronic devices 12.

[0067] In related technologies, electronic devices include filters and device bodies. The filters are fixedly connected to the device bodies via threaded connection components. These threaded connection components may loosen due to external forces such as vibration and impact. Therefore, anti-loosening measures are required for the connection between the filters and the device bodies.

[0068] Related technologies typically involve placing an elastic washer between the bolt head and the equipment body. When the bolt is tightened, the elastic washer is compressed, generating an outward elastic restoring force. This restoring force acts between the bolt head and the equipment body, creating a preload. This preload increases the contact pressure between the bolt head and the equipment body, thereby increasing friction to resist bolt loosening and achieving frictional anti-loosening between the bolt head and the equipment body.

[0069] However, elastic washers are made of elastic materials. Under long-term external force, the material will undergo elastic fatigue, which will weaken or even disappear the preload it provides, thus causing it to lose its anti-loosening function.

[0070] Figure 2 This is a schematic diagram of the structure of the filter 20 provided in the embodiment of this application. Figure 3This is a positional relationship diagram of the connector 200, threaded connector 300, and first anti-loosening member 400 provided in an embodiment of this application. In the diagram, the X-axis is defined as the length direction of the filter 20, the Y-axis is defined as the width direction of the filter 20, and the Z-axis is defined as the height direction of the filter 20.

[0071] In this embodiment, filter 20 can be an active filter or a passive filter. When the filter is a passive filter, filter 20 can be an electromagnetic compatibility (EMC) filter. An EMC filter can suppress electromagnetic interference within an electronic device. Specifically, an EMC filter filters high-frequency noise within the electronic device and attenuates electromagnetic interference signals, so that the electronic device is not affected by the external electromagnetic environment and does not interfere with other devices.

[0072] like Figure 2 As shown, the filter 20 includes a filter body 100, a connector 200, a threaded connector 300, and a first anti-loosening component 400. Among them, as... Figure 3 As shown, the connector 200 is fixedly connected to the filter body 100, and the connector 200 has a limiting part 220. Figure 3 As shown, the first anti-loosening component 400 includes a first component 410, at least one second component 420 and at least one third component 430. The second component 420 and the third component 430 are both connected to the first component 410. The first component 410 is located on the end face of the connector 200. The threaded connector 300 is used to be threadedly connected to the device body 10 of the electronic device in sequence via the first component 410 and the connector 200.

[0073] like Figure 3 As shown, the second component 420 is connected to the limiting portion 220 so that the connecting seat 200 restricts the rotation of the second component 420 relative to the connecting seat 200. The third component 430 abuts against the first side 311 of the head 310 of the threaded connector 300 to restrict the rotation of the threaded connector 300 relative to the connecting seat 200.

[0074] The number of connectors 200 can be one or more. When there are two or more connectors 200, the connectors 200 can be spaced apart. For example, each connector 200 can be arranged along a direction perpendicular to the thickness direction of the filter 20 (e.g., Figure 2 The Y-direction of the filter 20 is located on both sides of the filter body 100. Each connector 200 is connected to the device body 10. Multiple connectors 200 can improve the stability of the connection between the filter 20 and the device body 10.

[0075] During assembly, the connector 200 serves as the base for connecting the filter 20 to the device body 10. The threaded connector 300 is connected to the device body 10 of the electronic device via the first component 410 and the connector 200, thereby fixing the entire filter 20 to the device body 10.

[0076] When the second component 420 is connected to the limiting part 220, the connecting seat 200 can restrict the rotation of the second component 420 relative to the connecting seat 200 when the filter 20 is subjected to external forces such as vibration or impact. Since both the second component 420 and the third component 430 are connected to the first component 410, the connecting seat 200 can restrict the rotation of the third component 430 relative to the connecting seat 200. Based on this, by abutting the third component 430 against the first side 311 of the head 310 of the threaded connector 300, the third component 430 can restrict the rotation of the threaded connector 300 relative to the connecting seat 200, thereby achieving the anti-loosening of the threaded connector 300.

[0077] In this embodiment, mechanical anti-loosening is achieved by setting a first anti-loosening component 400. Compared with the frictional anti-loosening achieved by using the elastic deformation of elastic washers in related technologies, as long as the first anti-loosening component 400 does not break, the first anti-loosening component 400 can maintain its anti-loosening function. The probability of anti-loosening failure is lower than that of elastic washers, which can ensure the stability of the connection between the filter 20 and the device body 10, thereby ensuring the reliability of the operation of the filter 20.

[0078] In some embodiments, the filter body 100 includes other components that enable the filter 20 to function, such as capacitors, inductors, resistors, and ferrite elements.

[0079] In some possible implementations, the connector 200 has a first connecting hole 210, and the first component 410 has a second connecting hole 411. The threaded connector 300 is threadedly connected to the device body 10 via the first connecting hole 210 and the second connecting hole 411. In this way, the connector 200 can position the threaded connector 300 through the second connecting hole 411, and the threaded connector 300 can position and fix the first anti-loosening component 400 through the second connecting hole 411.

[0080] The first connecting hole 210 can be a through hole or a threaded hole. When the first connecting hole 210 is a through hole, the through hole can be a regular shape such as a round hole or a square hole, or it can be an irregular shape.

[0081] The second connecting hole 411 can be a through hole or a threaded hole. When the second connecting hole 411 is a through hole, the through hole can be a regular shape such as a round hole or a square hole, or it can be an irregular shape.

[0082] In some possible implementations, such as Figure 3As shown, the threaded connector 300 may include a head 310 and a rod 320 arranged sequentially. The rod 320 passes through the first connecting hole 210 and is threadedly connected to the device body 10. In this way, the filter 20 can be connected to the device body 10.

[0083] In some embodiments, the second component 420 and the limiting part 220 are fixedly connected by means of screwing, snap-fitting, or other methods. In this way, the connection between the second component 420 and the limiting part 220 is relatively stable, which can effectively prevent the second component 420 from rotating relative to the connecting seat 200.

[0084] In some embodiments, at least a portion of the second component 420 is bent toward the limiting portion 220, and at least a portion of the second component 420 extends toward the limiting portion 220.

[0085] After assembly, at least a portion of the second component 420 is bent toward the limiting portion 220, such that at least a portion of the second component 420 extends toward and connects with the limiting portion 220. For example, a portion of the second component 420 extends toward the limiting portion 220 while another portion does not. When the filter 20 is subjected to external forces such as vibration or impact, the limiting portion 220 can limit the second component 420 to prevent it from rotating relative to the connecting seat 200, thereby preventing the third component 430 from rotating. Alternatively, the second component 420 itself can be a bent part. After assembly, it is not necessary to bend the second component 420 to allow at least a portion of it to extend toward the limiting portion 220. This reduces the number of installation steps for the filter 20 and improves the installation efficiency of the filter 20.

[0086] In some embodiments, such as Figure 3 As shown, the limiting portion 220 is a side surface of the connector 200. For example, the limiting portion 220 can be a direction of the connector 200 perpendicular to the height direction of the filter 20 (e.g., ...). Figure 3 The second component 420 has a second side surface 421, which, exemplarily, can be the side surface of the connector 200 in the direction perpendicular to the height of the filter 20 (e.g., in the Y direction). Figure 3 The second side 421 abuts against the limiting part 220 on the side in the Y direction.

[0087] When the filter 20 is subjected to external forces such as vibration or impact, the threaded connector 300 will tend to rotate. At this time, the head 310 of the threaded connector 300 will transmit a rotational torque to the second component 420 through the first component 410 and the third component 430 of the first anti-loosening component 400, causing the second component 420 to also tend to rotate. Since the limiting part 220 and the second side surface 421 abut against each other, when the second component 420 tends to rotate due to the rotational torque, the limiting part 220 can physically block the second side surface 421 to prevent the second component 420 from rotating, thereby preventing the threaded connector 300 from rotating and thus achieving anti-loosening of the threaded connector 300. This ensures the stability of the connection between the filter 20 and the equipment body 10, thereby ensuring the reliability of the filter 20's operation.

[0088] In some possible implementations, the limiting part 220 is a plane, and the second side 421 is a plane. This reduces the processing difficulty of the connecting seat 200 and the first anti-loosening member 400, thereby reducing the manufacturing cost of the connecting seat 200 and the first anti-loosening member 400.

[0089] Of course, in addition to being a plane, the second side surface 421 can also be other non-circular surfaces other than a plane in some embodiments, such as a sawtooth surface, a curved surface, etc.

[0090] Of course, in addition to being a plane, the limiting part 220 can also be other non-circular surfaces other than a plane in some embodiments, such as a sawtooth surface, a curved surface, etc.

[0091] It is understood that the second side surface 421 and the limiting part 220 may be of the same or different types. For example, if they are different types, the second side surface 421 may be flat and the limiting part 220 may be serrated. This application embodiment does not limit the combination of the two types, as long as it can ensure that the limiting part 220 can restrict the rotation of the second side surface 421.

[0092] Figure 4 Another positional relationship diagram of the connector 200, threaded connector 300 and first anti-loosening member 400 provided in the embodiments of this application.

[0093] In some possible implementations, such as Figure 4 As shown, the number of limiting parts 220 is at least two, for example, the number of limiting parts 220 is two.

[0094] The number of second components 420 is at least two, for example, the number of second components 420 is two. Each second side 421 abuts against each limiting part 220.

[0095] Each second side 421 corresponds to each limiting part 220. Each limiting part 220 can restrict the rotation of the second side 421 in different directions, which can further improve the anti-loosening performance of the first anti-loosening member 400.

[0096] Figure 5 Another positional relationship diagram of the connector 200, threaded connector 300 and first anti-loosening member 400 provided in the embodiments of this application.

[0097] In some embodiments, such as Figure 5 As shown, the limiting part 220 is a first groove formed on the connecting seat 200, and at least a portion of the second component 420 is inserted into the first groove.

[0098] Since at least a portion of the second component 420 is inserted into the first groove, when the second component 420 tends to rotate due to the rotational torque, the sidewall of the first groove can physically block the second component 420 to prevent it from rotating, thereby preventing the threaded connector 300 from rotating and thus preventing the threaded connector 300 from loosening. This ensures the stability of the connection between the filter 20 and the device body 10, thereby ensuring the reliability of the filter 20's operation.

[0099] Furthermore, the second component 420 itself can be a bent part. After assembly, there is no need to bend the second component 420; at least a portion of the second component 420 can be located within the first groove. This design reduces the number of installation steps for the filter 20 and improves the installation efficiency of the filter 20.

[0100] In some possible implementations, the third component 430 is at least partially bent toward the head 310 of the threaded connector 300 and extends to one side of the first side 311.

[0101] With this configuration, after assembly, when the filter 20 is subjected to external forces such as vibration and impact, the third component 430 can limit the head 310 through the first side 311 to prevent the head 310 from rotating, thereby preventing the rod 320 from rotating, and thus achieving the anti-loosening of the threaded connector 300.

[0102] In some possible implementations, such as Figure 3 As shown, the third component 430 includes a third side surface 431. Exemplarily, the third side surface 431 can be the third component 430 along the length direction of the filter 20 (e.g., Figure 3 The third side 431 abuts against the first side 311 on the side in the X direction.

[0103] Therefore, the third component 430 can restrict the head 310 of the threaded connector 300 from rotating relative to the connector 200, so as to prevent the threaded connector 300 from loosening, and can ensure the stability of the connection between the filter 20 and the device body 10, thereby ensuring the reliability of the operation of the filter 20.

[0104] In some embodiments, the first side 311 is a plane, and the third side 431 is a plane. This configuration can reduce the processing difficulty of the head 310 and the first anti-loosening member 400, thereby reducing the manufacturing cost of the threaded connector 300 and the first anti-loosening member 400.

[0105] Of course, in addition to being a plane, the first side surface 311 can also be other non-circular surfaces besides a plane in some embodiments, such as a sawtooth surface, a curved surface, etc.

[0106] Of course, in addition to being a plane, the third side surface 431 can also be other non-circular surfaces other than a plane in some embodiments, such as a sawtooth surface, a curved surface, etc.

[0107] It is understood that the types of the first side surface 311 and the third side surface 431 can be the same or different. For example, if the types are different, the first side surface 311 may be a plane and the third side surface 431 may be a serrated surface. This application embodiment does not limit the combination of the two types, as long as it can ensure that the third side surface 431 can restrict the rotation of the first side surface 311.

[0108] In some possible implementations, such as Figure 4 As shown, the number of first side panels 311 is at least two, for example, the number of first side panels 311 is two.

[0109] The number of third components 430 is at least two, for example, there are two third components 430. Each third side 431 abuts against each first side 311. It is understood that the second component 420 can be directly connected to the first component 410, or the second component 420 can be connected to the first component 410 through the third component 430.

[0110] Since each first side 311 corresponds to each third side 431, each third side 431 can restrict the rotation of the first side 311 in different directions, which can further improve the anti-loosening performance of the first anti-loosening component 400.

[0111] In some embodiments, such as Figure 5As shown, the threaded connector 300 is a hexagonal head bolt. Since the head 310 of the hexagonal head bolt includes six planes, using a hexagonal head bolt makes it easier to prevent loosening of the threaded connector 300 when the third component 430 includes at least one third side 431, and the third side 431 is a plane. At the same time, the hexagonal head bolt has good anti-loosening performance. Furthermore, the hexagonal head bolt is an existing, mature structure. Using a hexagonal head bolt and the first anti-loosening component 400 to achieve anti-loosening can reduce the design cost of the threaded connector 300, thereby reducing the manufacturing cost of the filter 20.

[0112] In some embodiments, the forward projection of the second component 420 toward the connector 200 is located within the connector 200.

[0113] When the connector 200 is threaded to the device body 10 via the threaded connector 300, since the forward projection of the second component 420 toward the connector 200 is located within the connector 200, the second component 420 will not contact the device body 10, and no interference will occur between the second component 420 and the device body 10. Furthermore, the first anti-loosening component 400 achieves anti-loosening through the connector 200 and does not depend on the device body 10. Therefore, it is unnecessary to design a limiting structure (such as a plane or a first groove) on the device body 10 to limit the first anti-loosening component 400. This avoids the need for additional structural design on the device body 10 and ensures the structural integrity of the device body 10.

[0114] Figure 6 A positional relationship diagram of the connector 200, threaded connector 300, first anti-loosening member 400 and second anti-loosening member 500 provided in the embodiments of this application.

[0115] In some possible implementations, such as Figure 6 As shown, the connecting seat 200 has a second groove 230 on the side opposite to the first component 410, and the second groove 230 communicates with the first connecting hole 210.

[0116] The filter 20 may also include a second anti-loosening element 500, which is disposed in the second groove 230. The second anti-loosening element 500 has a threaded connection hole 510. The threaded connector 300 is threadedly connected to the second anti-loosening element 500 in sequence through the second connection hole 411, the first connection hole 210 and the threaded connection hole 510.

[0117] The second groove 230 can be a regular shape such as a circle, a regular pentagon or a regular hexagon, or it can be an irregular shape.

[0118] The second anti-loosening component 500 can be a regular shape such as a circle, a regular pentagon or a regular hexagon, or it can be an irregular shape.

[0119] The shape of the second groove 230 may be the same as or different from the shape of the second anti-loosening member 500. When the shape of the second groove 230 is different from the shape of the second anti-loosening member 500, it is necessary to ensure that the second groove 230 has a limiting effect on the second anti-loosening member 500.

[0120] The second anti-loosening component 500 can be fixedly connected to the inner wall of the second groove 230 by means of snap-fitting, bonding or other methods.

[0121] Regardless of whether the filter 20 is installed on the device body 10, when the second anti-loosening member 500 is set in the second groove 230 and the threaded connector 300 is threadedly connected to the second anti-loosening member 500 through the threaded connection hole 510, the connecting seat 200 can fix the second anti-loosening member 500, and the second anti-loosening member 500 can fix the threaded connector 300, thereby improving the stability of the connection between the threaded connector 300 and the connecting seat 200, so as to prevent the threaded connector 300 from loosening or falling off the connecting seat 200, thereby achieving the anti-loosening of the threaded connector 300.

[0122] In some possible implementations, the second anti-loosening component 500 is a nylon nut. Nylon nuts offer good anti-loosening performance, further enhancing the stability of the connection between the threaded connector 300 and the connector 200.

[0123] Figure 7 for Figure 2 Side view, Figure 8 for Figure 7 Enlarged view of point A in the image.

[0124] In some embodiments, such as Figure 7 As shown, the filter 20 also includes a wiring assembly 600, such as Figure 8 As shown, the wiring assembly 600 includes a terminal 610 and a first fastener 620, a first wedge washer 630, a second wedge washer 640, and a second fastener 650 that are sequentially threaded onto the terminal 610. The terminal 610 is fixedly connected to the filter body 100. The terminal 610, the first fastener 620, the first wedge washer 630, the second wedge washer 640, and the second fastener 650 are all conductive components.

[0125] The first fastener 620 and the first wedge washer 630 are used together to clamp the cable, or the second fastener 650 and the first wedge washer 630 are used together to clamp the cable. The cable can be a grounding cable or a power cable, etc. The terminal 610, the first fastener 620, the first wedge washer 630, the second wedge washer 640, and the second fastener 650 are all conductive components, enabling electrical connection between the cable and the filter 20.

[0126] The first wedge washer 630 and the second wedge washer 640 are both existing structural designs in the art, and will only be briefly described here:

[0127] Both the first wedge washer 630 and the second wedge washer 640 include wedge-shaped toothed surfaces and radial fine teeth. When the first fastener 620 and the second fastener 650 are tightened, the two radial fine teeth contact the first fastener 620 and the second fastener 650 respectively, and the two wedge-shaped toothed surfaces mesh and lock. Compared with a smooth plane, the friction between each fastener and each radial fine tooth is greater, making the first fastener 620 and the second fastener 650 less prone to loosening. In addition, the included angle between the wedge-shaped toothed surfaces of the first wedge washer 630 and the second wedge washer 640 is greater than the helix angle of the terminal 610. When loosening occurs, the amount of axial thickening of each wedge washer is greater than the amount of axial creep of the threads of each fastener, thereby increasing the axial preload of the first fastener 620 and the second fastener 650, which can effectively prevent the first fastener 620 and the second fastener 650 from loosening.

[0128] In some embodiments, such as Figure 8 As shown, the filter 20 may further include an elastic washer 660, which is disposed between the filter body 100 and the first fastener 620. The elastic washer 660 provides a preload to prevent loosening due to friction between the first fastener 620 and the filter body 100, making it less prone to loosening.

[0129] Figure 9 This is a cross-sectional schematic diagram of the filter 20 provided in an embodiment of this application.

[0130] In some possible implementations, such as Figure 9 As shown, the filter body 100 includes a heat-conducting outer shell 110, a heat-conducting inner shell 120, and a heating element. The heat-conducting outer shell 110 has a receiving cavity, and the heat-conducting inner shell 120 is disposed inside the heat-conducting outer shell 110. The heat-conducting inner shell 120 divides the receiving cavity into a first sub-cavity 111 and a second sub-cavity 112. The first sub-cavity 111 is located between the heat-conducting outer shell 110 and the heat-conducting inner shell 120, and the second sub-cavity 112 is located inside the heat-conducting inner shell 120. The second sub-cavity 112 is used to accommodate the heating element of the filter 20. The heat-conducting outer shell 110 also has at least one first vent 113 and at least one second vent 114. Both the first vent 113 and the second vent 114 communicate with the first sub-cavity 111 and the outside of the heat-conducting outer shell 110, along the height direction of the filter 20 (e.g., ...). Figure 9(in the Z direction), the second vent 114 is located above the first vent 113. The heat-conducting inner shell 120 has at least one third vent 121 and at least one fourth vent 122, both of which connect the first sub-cavity 111 and the second sub-cavity 112. Along the height direction of the filter 20, the fourth vent 122 is located above the third vent 121.

[0131] The number of first vents 113 can be one or more. When there are multiple first vents 113, each first vent 113 can be arranged on the same side or different sides of the heat-conducting housing 110 along a direction perpendicular to the height direction of the filter 20. This arrangement can increase the amount of air entering.

[0132] The shape of the first ventilation opening 113 is not limited in this embodiment. For example, the first ventilation opening 113 may be a regular shape such as circular, elliptical, or square, or it may be an irregular shape.

[0133] The number of second vents 114 can be one or more. When there are multiple second vents 114, each second vent 114 can be arranged on the same side or different sides of the heat-conducting housing 110 along a direction perpendicular to the height direction of the filter 20. This arrangement can increase the airflow.

[0134] The shape of the second vent 114 is not limited in this application embodiment. For example, the second vent 114 may be a regular shape such as circular, elliptical, or square, or it may be an irregular shape.

[0135] The number of third vents 121 can be one or more. When there are multiple third vents 121, each third vent 121 can be arranged on the same side or different sides of the heat-conducting inner shell 120 along a direction perpendicular to the height direction of the filter 20. This arrangement can increase the amount of air entering.

[0136] The shape of the third ventilation opening 121 is not limited in this embodiment. For example, the third ventilation opening 121 may be a regular shape such as circular, elliptical, or square, or it may be an irregular shape.

[0137] The number of fourth vents 122 can be one or more. When there are multiple fourth vents 122, each fourth vent 122 can be arranged on the same side or different sides of the heat-conducting inner shell 120 along a direction perpendicular to the height direction of the filter 20. This arrangement can increase the airflow.

[0138] The shape of the fourth ventilation opening 122 is not limited in this embodiment. For example, the fourth ventilation opening 122 may be a regular shape such as circular, elliptical, or square, or it may be an irregular shape.

[0139] It is understandable that the number of the first ventilation opening 113, the second ventilation opening 114, the third ventilation opening 121, and the fourth ventilation opening 122 may be the same or different.

[0140] It is understood that the shapes of the first vent 113, the second vent 114, the third vent 121, and the fourth vent 122 may be the same, or at least two of the first vent 113, the second vent 114, the third vent 121, and the fourth vent 122 may have different shapes.

[0141] When the filter 20 is operating, the heating element located in the second sub-cavity 112 generates heat. Cold air with a lower temperature and higher density from the external environment is naturally drawn into the first sub-cavity 111 through the first vent 113 at the bottom of the heat-conducting outer shell 110. Subsequently, this cold air continues to flow into the second sub-cavity 112 through the third vent 121 at the bottom of the heat-conducting inner shell 120, directly reaching the vicinity of the heating element. As the cold air flows past the heating element, it absorbs a large amount of heat, causing its temperature to rise and its density to decrease. This heated air naturally rises and flows out of the second sub-cavity 112 through the fourth vent 122 at the top of the heat-conducting inner shell 120, returning to the upper space of the first sub-cavity 111. Finally, the hot air collected in the upper part of the first sub-cavity 111 is discharged to the outside of the filter 20 through the second vent 114 at the top of the heat-conducting outer shell 110.

[0142] The filter body 100 of this application embodiment utilizes the physical principle that hot air has a low density and cold air has a high density to construct a self-driven natural convection heat dissipation circuit that does not require additional power (such as a fan), which can effectively dissipate heat from heat-generating components and achieve heat dissipation at a low cost.

[0143] In some embodiments, such as Figure 9 As shown, along the height direction of filter 20 (e.g.) Figure 9 In the Z direction of the filter 20, the end of the second vent 114 near the first sub-cavity 111 is lower than the end away from the first sub-cavity 111. Along the height direction of the filter 20, the end of the fourth vent 122 near the second sub-cavity 112 is lower than the end away from the second sub-cavity 112.

[0144] Both the second vent 114 and the fourth vent 122 slope upwards from the inside to the outside of the heat-conducting housing 110, forming an upward-sloping exhaust channel from the inside to the outside. Since air, which becomes less dense after heating, naturally rises, the upward-sloping exhaust channel adapts to the natural movement of hot air, reducing the flow resistance and energy loss at the outlet, making the exhaust process smoother and accelerating the airflow velocity throughout the air circulation loop. This means that more heat is expelled from the filter 20 per unit time, thereby improving the heat dissipation efficiency of the filter 20.

[0145] In some embodiments, such as Figure 9 As shown, along the height direction of filter 20 (e.g.) Figure 9 (As shown in the Z direction), the end of the first vent 113 near the first sub-cavity 111 is lower than the end away from the first sub-cavity 111. Along the height direction of the filter 20, the end of the third vent 121 near the second sub-cavity 112 is lower than the end away from the second sub-cavity 112.

[0146] Or in other embodiments, along the height direction of filter 20 (e.g.) Figure 9 (As shown in the Z direction), the end of the first vent 113 near the first sub-cavity 111 is higher than the end away from the first sub-cavity 111. Along the height direction of the filter 20, the end of the third vent 121 near the second sub-cavity 112 is higher than the end away from the second sub-cavity 112.

[0147] In some embodiments, both the thermally conductive outer shell 110 and the thermally conductive inner shell 120 can be used to conduct heat, with the thermal conductivity of the inner shell 120 being greater than that of the outer shell 110. Thus, the inner shell 120 can rapidly absorb heat, while the outer shell 110 can efficiently dissipate heat, thereby improving the heat dissipation effect of the filter 20.

[0148] In some possible implementations, the thermally conductive housing 110 has at least one first vent group and at least one second vent group, each first vent group including a plurality of first vents 113, which can be arranged in an array, for example along the height direction of the filter 20 (e.g., Figure 9 The Z-direction shown) and / or the length direction of filter 20 (as shown) Figure 9 As shown in the X direction, each second vent group includes multiple second vents 114, which can be arranged in an array, for example, along the height direction and / or the length direction of the filter 20. Along the height direction of the filter 20, the second vent group is located above the first vent group.

[0149] The heat-conducting inner shell 120 has at least one third vent group and at least one fourth vent group. The third vent group includes multiple third vents 121, which can be arranged in an array, for example, along the height direction and / or the length direction of the filter 20. The fourth vent group includes multiple fourth vents 122, which can also be arranged in an array, for example, along the height direction and / or the length direction of the filter 20. Along the height direction of the filter 20, the fourth vent group is located above the third vent group.

[0150] With this configuration, within the same area, compared to setting a single large vent, such as a single second vent 114, a single large vent results in a smaller contact area between the filter body 100 and the airflow. However, by setting a group of vents, that is, setting multiple small vents arranged in an array, such as multiple second vents 114 arranged in an array, the contact area between the filter body 100 and the airflow can be increased. For example, the contact area between the heat-conducting outer shell 110 of the filter body 100 and the airflow can be increased, so that the airflow can carry away more of the heat conducted by the filter body 100, thereby improving the heat dissipation efficiency of the filter 20.

[0151] The number of the first, second, third, and fourth vent groups can each be one or more. When there are multiple groups, the air intake and air outflow can be increased.

[0152] In some embodiments, the filter body 100 may further include a top shell 130 and a bottom shell 140. The top shell 130 may be fixedly connected to the top of the heat-conducting outer shell 110 and the heat-conducting inner shell 120, and the bottom shell 140 may be fixedly connected to the bottom of the heat-conducting outer shell 110 and the heat-conducting inner shell 120. The bottom shell 140 may close the bottom of the receiving cavity, and the top shell 130 may close the top of the receiving cavity.

[0153] In some embodiments, such as Figure 9 As shown, the filter 20 also includes a liquid cooling heat dissipation assembly 700, which includes a heat-conducting element 710 and a liquid cooling pipe 720. The heat-conducting element 710 has a channel 711, and the liquid cooling pipe 720 is located within the channel 711. The liquid cooling pipe 720 is used to dispose of coolant. Exemplarily, the liquid cooling pipe 720 includes an inlet and an outlet, the inlet for coolant to enter, and the outlet for coolant to flow out.

[0154] The heat-conducting component 710 can be disposed on the bottom shell 140, or the heat-conducting component 710 can be connected to the bottom shell 140, and the heat-conducting component 710 and the bottom shell 140 together seal the bottom of the receiving cavity.

[0155] The heat-generating element of the filter 20 can be mounted on the liquid cooling heat dissipation assembly 700, or it can be mounted on one side of the liquid cooling heat dissipation assembly 700. The heat dissipated by the heat-generating element can be transferred to the liquid cooling pipe 720 through the heat-conducting component 710.

[0156] When the coolant flows inside the liquid cooling pipe 720, the coolant can absorb the heat on the liquid cooling pipe 720 and carry it to the outside of the liquid cooling pipe 720, thereby achieving liquid cooling heat dissipation for the heat-generating components.

[0157] Of course, in addition to including the liquid cooling pipe 720, in some embodiments, the liquid cooling heat dissipation assembly 700 may also omit the liquid cooling pipe 720. In this case, the channel 711 can be used to contain coolant, the inlet of the channel 711 can be used for coolant to enter, and the outlet of the channel 711 can be used for coolant to flow out.

[0158] Of course, in addition to including the heat-conducting component 710 and the liquid cooling pipe 720, in some embodiments, the liquid cooling heat dissipation component 700 may also include devices that enable it to function, such as liquid storage components, water pumps, etc.

[0159] In some possible implementations, the heat-conducting component 710 may also be called a liquid cooling plate.

[0160] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
