Description
Technical Field
[0001] This application relates to the field of electromagnetic shielding technology, and more particularly to an electronic device. Background Technology
[0002] Electromagnetic shielding components are commonly found in electronic devices such as computing and communication equipment. In related technologies, these components consist of two connected metal structural members that enclose an electromagnetic shielding space, facilitating the assembly of electronic components within this space. However, in these technologies, electromagnetic leakage is prone to occur at the connection point between the two metal structural members, and the electromagnetic shielding effectiveness of the components needs further improvement. Utility Model Content
[0003] This application provides an electronic device that has a good electromagnetic shielding effect.
[0004] This application provides an electronic device comprising a first metal structural component, a second metal structural component, and a compressible conductive component. The first metal structural component includes a first connecting portion, and the second metal structural component includes a second connecting portion. The first and second metal structural components are connected via the first and second connecting portions, and are used to enclose an electromagnetic shielding space. The first connecting portion includes a plug-in structure, and the second connecting portion has a slot. The plug-in structure is inserted into the slot, and a bent gap channel exists between the slot wall and the plug-in structure. This bent gap channel, also known as a labyrinth channel, creates a labyrinth structure between the plug-in structure and the slot wall. The conductive component is pressed into the gap channel, and is in electrical contact with both the slot wall and the plug-in structure, thus electrically connecting the first and second metal structural components.
[0005] The electromagnetic shielding assembly provided in this application embodiment has a bent gap channel between the plug-in structure and the slot. This bent gap channel increases the complexity of the propagation path and the number of reflections of electromagnetic waves at the connection between the first and second metal structural components. This reduces electromagnetic leakage at the connection by attenuating electromagnetic energy, thereby improving the electromagnetic shielding effect. Furthermore, by pressing a conductive element between the plug-in structure and the slot wall, the conductive element can be in close contact with both the slot wall and the plug-in structure. This ensures a stable and reliable electrical connection between the first and second metal structural components, making the electrical connection at the connection continuous and reliable, thus reducing the likelihood of electromagnetic waves leaking through the gap between the plug-in structure and the slot. In addition, pressing a conductive element between the slot wall and the plug-in structure disrupts the cavity resonance condition of the gap channel formed between the plug-in structure and the slot, suppressing cavity resonance and reducing the negative impact on the shielding effectiveness of the electromagnetic shielding assembly caused by cavity resonance at the connection between the first and second metal structural components. In this way, the connection between the first metal structural component and the second metal structural component can achieve a good electromagnetic shielding effect.
[0006] In addition, by pressing the conductive component between the slot wall and the plug-in structure, the electromagnetic shielding effect after the first metal structural component and the second metal structural component are connected can be improved. While the electromagnetic shielding effect is good, the structural accuracy requirements of the first and second connecting parts can be reduced. The first and second connecting parts can have larger tolerances, which makes the assembly of the first and second metal structural components easier and the manufacturing cost lower.
[0007] For example, the slot has a plug-in interface, the slot wall includes a bottom wall, the bottom wall and the plug-in interface are located on both sides of the slot in the depth direction, and the plug-in structure passes through the plug-in interface.
[0008] In some possible implementations, the conductive element is pressed between the bottom wall and the plug structure.
[0009] This makes it easier to press the conductive component into the predetermined position in the slot, so as to achieve close contact between the conductive component and the first and second metal structural components, and the installation of the conductive component in the slot is relatively easy.
[0010] In some possible implementations, the gap between the bottom wall and the insertion structure along the depth direction of the slot is less than or equal to 2 mm.
[0011] This allows the plug-in structure and the bottom wall to press the conductive element located between them together, so that the conductive element can be in close contact with the first metal structural element and the second metal structural element.
[0012] In some possible implementations, the conductive element is bonded to the plug structure.
[0013] In this way, the conductive component can be inserted into the slot along with the plug-in structure, making it easier to install the conductive component. Furthermore, when the plug-in structure is pulled out of the slot, the conductive component can be pulled out along with it, making it convenient to remove the conductive component from the slot.
[0014] In some possible implementations, the conductive element is bonded to the end face of the plug structure near the bottom wall.
[0015] In this way, the conductive component is less likely to shift relative to the plug-in structure during insertion and removal, making it easier to install and remove the conductive component from the slot. Furthermore, it facilitates pressing the conductive component into a predetermined position within the slot to achieve tight contact between the conductive component and the first and second metal structural components.
[0016] In some possible implementations, the portion of the plug structure located within the slot has a dimension greater than or equal to 1 cm in the depth direction of the slot.
[0017] In this way, the gap channel formed between the plug-in structure and the slot is relatively deep, which has a better attenuation effect on electromagnetic waves, and electromagnetic leakage is less likely to occur at the connection between the first metal structural component and the second metal structural component.
[0018] In some possible implementations, the conductive element is an elastic element.
[0019] In this way, after the conductive component is compressed, its elastic restoring force allows it to make close contact with both the first and second metal structural components, ensuring a stable and reliable electrical connection at their joint. Furthermore, the conductive component can be reused after the first and second metal structural components are separated, making maintenance more convenient and cost-effective.
[0020] In some possible implementations, the compression ratio of the conductive element is greater than or equal to 30% and less than or equal to 70%.
[0021] Thus, a compression ratio of 30% or greater for the conductive component ensures close contact between the conductive component and the first and second metal structural components, resulting in better electromagnetic shielding after the connection of the first and second metal structural components. A compression ratio of less than 70% for the conductive component, when the conductive component is elastic, provides good resilience, facilitating close contact between the conductive component and the first and second metal structural components, further enhancing the electromagnetic shielding effect after the connection. Furthermore, this also helps to extend the service life of the conductive component, making the electromagnetic shielding effect after the connection of the first and second metal structural components more stable.
[0022] In some possible implementations, the conductive element is a conductive cloth, conductive foam, or conductive adhesive strip.
[0023] In this way, the conductive component has good elasticity and can have a high compression ratio, which is conducive to close contact between the conductive component and the first and second metal structural components, resulting in a better electromagnetic shielding effect after the first and second metal structural components are connected.
[0024] In some possible implementations, the first metal structural member further includes a first main body portion, and the first connecting portion further includes a first sub-part. The plug-in structure is staggered with the first main body portion along the width direction of the slot, and the plug-in structure is connected to the first main body portion through the first sub-part. The plug-in structure and the first main body portion are respectively located on both sides of the first sub-part in the depth direction of the slot.
[0025] The second metal structural member also includes a second main body portion, and the second connecting portion includes a second sub-part, a third sub-part, and a fourth sub-part. The third and fourth sub-parts are both connected to the second sub-part, and the second, third, and fourth sub-parts are used to enclose and form a slot. The second sub-part is located on one side of the slot in the depth direction. The third and fourth sub-parts are located on opposite sides of the slot in the width direction. The second main body portion is located on the side of the second sub-part away from the third and fourth sub-parts along the depth direction of the slot.
[0026] In this way, the insertion of the plug-in structure into the slot is more convenient, facilitating the connection between the first and second metal structural components. Furthermore, the plug-in structure and the first main body are staggered along the width of the slot, which helps to reduce the discontinuity on the outer surfaces of the first and second metal structural components after they are connected by the first and second connecting parts.

[0044] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0045] This application provides an electronic device, which may include, but is not limited to, computing devices and communication devices. For example, computing devices may include, but are not limited to, servers, supercomputers, edge computing devices, dedicated computing devices, micro data centers, cloud computing devices, artificial intelligence training devices, data processing devices, and industrial IoT devices. Communication devices may include, but are not limited to, terminal devices, base station devices, access network devices, core network devices, and satellite devices.
[0046] Figure 1 This is a schematic diagram of an electronic device with its top cover closed, provided in an embodiment of this application. Figure 2 This is a schematic diagram of an electronic device with its top cover open, as provided in an embodiment of this application.
[0047] like Figure 1 , Figure 2 As shown, the electronic device includes a housing 10 and electronic components 20 disposed within the housing 10. The housing 10 includes a top cover 11 and a bottom cover 12, which are two independent components. The top cover 11 and the bottom cover 12 are fixedly connected, and the electronic components 20 are disposed within the space formed by the top cover 11 and the bottom cover 12.
[0048] This application also provides an electromagnetic shielding component. The electromagnetic shielding component may include, but is not limited to, an electromagnetic shielding cover, a housing 10, etc. An electronic device may include the electromagnetic shielding component. Alternatively, the electromagnetic shielding component may be a component of the electronic device.
[0049] This application uses the electromagnetic shielding component as the housing 10 of an electronic device as an example for illustration.
[0050] like Figure 1 , Figure 2 As shown, the electromagnetic shielding assembly includes a first metal structural member 100 and a second metal structural member 200. The first metal structural member 100 includes a first connecting portion 110, located on the side of the first metal structural member 100 closest to the second metal structural member 200. The second metal structural member 200 includes a second connecting portion 210, located on the side of the second metal structural member 200 closest to the first metal structural member 100. The first metal structural member 100 and the second metal structural member 200 are connected via the first connecting portion 110 and the second connecting portion 210. The first metal structural member 100 and the second metal structural member 200 are used to enclose and form an electromagnetic shielding space C, within which electronic components 20 are disposed.
[0051] For example, the electromagnetic shielding space C can be formed by the first metal structural member 100 and the second metal structural member 200. The electromagnetic shielding space C can also be formed by the first metal structural member 100, the second metal structural member 200 and other structural members together.
[0052] When the electromagnetic shielding component is the housing 10 of an electronic device, one of the first metal structural member 100 and the second metal structural member 200 is a top cover 11, and the other of the first metal structural member 100 and the second metal structural member 200 is a bottom shell 12. The top cover 11 and the bottom shell 12 are used to enclose and form an electromagnetic shielding space C. That is to say, the housing 10 is a metal housing 10, and the top cover 11 and the bottom shell 12 are both made of metal. The housing 10 can play the role of electromagnetic shielding.
[0053] For example, the first metal structural member 100 further includes a first main body portion 120, and a first connecting portion 110 is connected to the side of the first main body portion 120 near the second metal structural member 200. The first connecting portion 110 and the first main body portion 120 are integrally formed. The second metal structural member 200 further includes a second main body portion 220, and a second connecting portion 210 is connected to the side of the second main body portion 220 near the first metal structural member 100. The second connecting portion 210 and the second main body portion 220 are integrally formed. The first main body portion 120 and the second main body portion 220 are connected through the first connecting portion 110 and the second connecting portion 210.
[0054] Figure 3 This is a cross-sectional schematic diagram from one perspective of an electromagnetic shielding component provided in an embodiment of this application. Figure 4 for Figure 3 The diagram shows a cross-sectional view of the electromagnetic shielding assembly provided. In the diagram, direction a is the first direction, direction b is the second direction, and direction c is the third direction.
[0055] like Figure 3 , Figure 4 As shown, the first connecting portion 110 includes a plug-in structure 111, and the second connecting portion 210 has a slot G1. The first direction is the depth direction of the slot G1, the second direction is the width direction of the slot G1, and the third direction is the length direction of the slot G1. The plug-in structure 111 is inserted into the slot G1. Specifically, the plug-in structure 111 is inserted into the slot G1 along the first direction. The depth direction of the slot G1 is the insertion / removal direction between the plug-in structure 111 and the slot G1; that is, the first direction is also the insertion / removal direction between the plug-in structure 111 and the slot G1. A bent gap channel exists between the slot wall of the slot G1 and the plug-in structure 111. This bent gap channel can also be called a labyrinth channel, causing the plug-in structure 111 and the slot wall of the slot G1 to form a labyrinth structure. This increases the complexity of the propagation path and the number of reflections of electromagnetic waves at the connection between the first metal structure 100 and the second metal structure 200, thereby reducing electromagnetic leakage at the connection between the first metal structure 100 and the second metal structure 200 by attenuating electromagnetic energy, thus improving the electromagnetic shielding effect.
[0056] For example, the first connecting part 110 and the second connecting part 210 engage with the slot G1 through the plug-in structure 111.
[0057] For example, slot G1 has a plug-in interface H. The slot wall of slot G1 includes a bottom wall 2111, a first side wall 2121, and a second side wall 2131. The bottom wall 2111 and the plug-in interface H are located on both sides of the slot G1 in the depth direction, and the first side wall 2121 and the second side wall 2131 are located on both sides of the slot G1 in the width direction. The first side wall 2121 and the second side wall 2131 are used to enclose and form the plug-in interface H. The plug-in structure 111 passes through the plug-in interface H. Along the second direction, the plug-in structure 111 is located between the first side wall 2121 and the second side wall 2131. The insertion structure 111 has gaps between itself and the first side wall 2121, the second side wall 2131, and the bottom wall 2111. The gaps between the insertion structure 111 and the first side wall 2121, the gaps between the insertion structure 111 and the bottom wall 2111, and the gaps between the insertion structure 111 and the second side wall 2131 are connected to form a bent gap channel.
[0058] For example, the plug-in structure 111 includes an insertion end and a connection end, which are located at the two ends of the plug-in structure 111 in the first direction. The insertion end is the end of the plug-in structure 111 near the bottom wall 2111 and is located inside the slot G1. The connection end is fixedly connected to the first main body 120 and can be located outside the slot G1. The insertion end is inserted into the slot G1 through the plug interface H.
[0059] In some examples, the plug-in structure 111 is offset from the first main body portion 120 along a second direction. The first connecting portion 110 also includes a first sub-portion 112, through which the plug-in structure 111 is fixedly connected to the first main body portion 120, in order to reduce the discontinuity on the outer surfaces of the first metal structural member 100 and the second metal structural member 200 after they are connected by the first connecting portion 110 and the second connecting portion 210.
[0060] For example, the second connecting portion 210 includes a second sub-portion 211, a third sub-portion 212, and a fourth sub-portion 213. The third sub-portion 212 and the fourth sub-portion 213 are both connected to the second sub-portion 211. The second sub-portion 211, the third sub-portion 212, and the fourth sub-portion 213 are used to enclose and form a slot G1. The second sub-portion 211 is located on one side of the slot G1 in the depth direction, and the third sub-portion 212 and the fourth sub-portion 213 are located on both sides of the slot G1 in the width direction.
[0061] For example, the third sub-part 212 and the fourth sub-part 213 are arranged opposite to each other and spaced apart along the second direction. The third sub-part 212 and the fourth sub-part 213 are located on the same side of the second sub-part 211 in the first direction. The second sub-part 211 is used to form the bottom wall 2111 of the slot G1, the third sub-part 212 is used to form the first side wall 2121 of the slot G1, and the fourth sub-part 213 is used to form the second side wall 2131 of the slot G1.
[0062] For example, the dimensions of the third sub-part 212 and the fourth sub-part 213 in the depth direction of the slot G1 may be the same or different. The overlapping portion of the third sub-part 212 and the fourth sub-part 213 is used to form the first sidewall 2121, and the overlapping portion of the fourth sub-part 213 and the third sub-part 212 is used to form the second sidewall 2131.
[0063] In some examples, the plug-in structure 111 and the first main body 120 are located on both sides of the first sub-part 112 in the first direction, and the second main body 220 is located on the side of the second sub-part 211 away from the third sub-part 212 and the fourth sub-part 213 in the first direction, making it easier to plug the plug-in structure 111 into the slot G1.
[0064] In some examples, along the second direction, the outer surface of the third sub-part 212 is flush with the outer surface of the second main body 220.
[0065] In some examples, along the second direction, the outer surface of the third sub-part 212 is flush with the outer surface of the first main body 120.
[0066] like Figure 4 As shown, the portion of the insertion structure 111 located within the slot G1 has a depth dimension of d1 in the slot G1. That is, the portion of the insertion structure 111 that overlaps with the first sidewall 2121 and the second sidewall 2131 has a depth dimension of d1 in the slot G1. Alternatively, the portion of the insertion structure 111 that overlaps with both the third sub-part 212 and the fourth sub-part 213 has a depth dimension of d1 in the slot G1. At this time, the gap formed between the insertion structure 111 and the first sidewall 2121 and the second sidewall 2131 has a depth dimension of d1 in the slot G1.
[0067] For example, along the depth direction of slot G1, the distance between the insertion end and the end of the third sub-part 212 away from the second sub-part 211 is D1, and the distance between the insertion end and the end of the fourth sub-part 213 away from the second sub-part 211 is D2. When D1 and D2 are equal, both D1 and D2 are equal to d1. When D1 and D2 are not equal, d1 is equal to the smaller of D1 and D2.
[0068] The gap channel formed between the plug-in structure 111 and the slot G1 will experience cavity resonance, leading to a decrease in the shielding effectiveness of the electromagnetic shielding assembly at the resonant frequency of the cavity resonance. Specifically, cavity resonance will occur in both the length and depth directions of the gap channel formed between the plug-in structure 111 and the slot G1. The depth direction of the gap channel is the same as the depth direction of the slot G1, and the length direction is the same as the length direction of the slot G1. The wavelength of the lowest resonant frequency of the cavity resonance generated in the length direction of the gap channel is twice the length of the gap channel. Since the gap channel is often relatively long, the wavelength and resonant frequency of the cavity resonance generated in the length direction of the gap channel are often relatively long and relatively low.
[0069] Figure 5 This is a shielding effectiveness curve of an electromagnetic shielding component. Figure 5 To pass Figure 3 , Figure 4 The diagram shows the shielding effectiveness curves of an electromagnetic shielding assembly formed by a first metal structural member 100 and a second metal structural member 200 connected in a labyrinth structure (no conductive element 300 is provided between the slot wall of slot G1 and the plug-in structure 111). L1 represents the shielding effectiveness curve when d1 = 4 mm, L2 represents the shielding effectiveness curve when d1 = 10 mm, and L3 represents the shielding effectiveness curve when d1 = 20 mm. Figure 5 As shown, due to cavity resonance generated along the length of the gap channel, the shielding effectiveness of L1, L2, and L3 is poor in the low-frequency band below 3 GHz. When d1 = 20 mm, the resonant frequency of the cavity resonance generated along the depth of the gap channel falls between 5 GHz and 8 GHz, resulting in poor shielding effectiveness of L3 in the 5 GHz to 8 GHz band.
[0070] like Figure 3 , Figure 4 As shown in the embodiment of this application, the electromagnetic shielding assembly further includes a compressible conductive element 300, which is pressed into the gap channel. That is, the conductive element 300 is pressed between the slot wall of the slot G1 and the plug-in structure 111. The conductive element 300 is in electrical contact with both the slot wall of the slot G1 and the plug-in structure 111. The conductive element 300 enables the first metal structure 100 to be electrically connected to the second metal structure 200.
[0071] In this way, by compressing the conductive element 300, it is pressed into the gap channel formed between the slot wall of the slot G1 and the plug-in structure 111. This ensures close contact between the conductive element 300 and the slot wall of the slot G1 and the plug-in structure 111, thereby enabling a stable and reliable electrical connection between the first metal structural element 100 and the second metal structural element 200. This ensures a continuous and reliable electrical connection at the connection point between the first metal structural element 100 and the second metal structural element 200, making it less likely for electromagnetic waves to leak through the gap channel between the plug-in structure 111 and the slot G1. Furthermore, by pressing the conductive element 300 between the slot wall of the slot G1 and the plug-in structure 111, the cavity resonance condition of the gap channel formed between the plug-in structure 111 and the slot G1 can be disrupted. This suppresses cavity resonance in the gap channel between the plug-in structure 111 and the slot G1, reducing the negative impact on the shielding effectiveness of the electromagnetic shielding assembly caused by cavity resonance at the connection point between the first metal structural element 100 and the second metal structural element 200. In this way, the electromagnetic shielding components can have a better electromagnetic shielding effect.
[0072] In addition, by pressing the conductive element 300 between the slot wall of the slot G1 and the plug-in structure 111, the electromagnetic shielding effect of the electromagnetic shielding assembly can be improved. While the electromagnetic shielding effect is good, the structural accuracy requirements of the first connecting part 110 and the second connecting part 210 can be reduced. The first connecting part 110 and the second connecting part 210 can have larger tolerances, which makes the assembly of the electromagnetic shielding assembly easier and the manufacturing cost lower.
[0073] It should be noted that the conductive component 300 in this application refers to the conductive component located in the gap channel between the slot wall of the slot G1 and the plug-in structure 111. Other conductive components may also be provided at other locations of the electromagnetic shielding assembly.
[0074] In some possible implementations, the conductive element 300 is pressed between the bottom wall 2111 and the plug structure 111.
[0075] This makes it easier to press the conductive element 300 into the predetermined position in the slot G1, so as to achieve close contact between the conductive element 300 and the first metal structure 100 and the second metal structure 200, and the installation of the conductive element 300 in the slot G1 is relatively easy.
[0076] For example, the conductive element 300 is pressed between the bottom wall 2111 and the insertion end.
[0077] In some possible implementations, the distance between the bottom wall 2111 and the insertion structure 111 along the depth direction of the slot G1 is d2. That is, the distance between the bottom wall 2111 and the end face of the insertion end is d2. d2 is less than or equal to 2 mm.
[0078] This allows the plug-in structure 111 and the bottom wall 2111 to press the conductive element 300 located between them together, so that the conductive element 300 can be in close contact with the first metal structure 100 and the second metal structure 200.
[0079] For example, d2 can be 4.5mm, 1mm, 0.75mm, etc.
[0080] In some possible implementations, the conductive element 300 is bonded to the plug-in structure 111.
[0081] In this way, the conductive element 300 can be inserted into the slot G1 along with the plug-in structure 111, making it easier to insert the conductive element 300 into the slot G1. In addition, when the plug-in structure 111 is pulled out of the slot G1, the conductive element 300 can be pulled out with it, making it easier to remove the conductive element 300 from the slot G1.
[0082] For example, during the assembly of the electromagnetic shielding assembly, the conductive element 300 can be first bonded to the plug-in structure 111, and then the plug-in structure 111 with the conductive element 300 bonded to it can be inserted into the slot G1, so that the plug-in structure 111 and the slot G1 are engaged, and the conductive element 300 is pressed tightly, thereby compressing the conductive element 300.
[0083] In some possible implementations, the conductive element 300 is bonded to the end face of the insertion structure 111 near the bottom wall 2111. That is, the conductive element 300 is bonded to the end face of the insertion end.
[0084] In this way, the conductive component 300 is less likely to shift relative to the insertion structure 111 when it is inserted or removed, making it easier to install and remove the conductive component 300 from the slot G1. Furthermore, it facilitates pressing the conductive component 300 into a predetermined position within the slot G1 to achieve tight contact between the conductive component 300 and the first metal structural component 100 and the second metal structural component 200.
[0085] In some possible implementations, d1 is greater than or equal to 1 cm.
[0086] In this way, the gap channel formed between the plug-in structure 111 and the slot G1 is relatively deep, which has a better attenuation effect on electromagnetic waves, and electromagnetic leakage is less likely to occur at the connection between the first metal structure 100 and the second metal structure 200.
[0087] For example, d1 can be 1.5cm, 2cm, 2.5cm, etc.
[0088] In some possible implementations, the conductive element 300 is an elastic element.
[0089] In this way, after the conductive component 300 is compressed, the elastic restoring force of the conductive component 300 allows it to make close contact with the first metal structural component 100 and the second metal structural component 200, thus ensuring a stable and reliable electrical connection between them. Furthermore, the conductive component 300 can be reused after the first metal structural component 100 and the second metal structural component 200 are separated, making maintenance more convenient and cost-effective.
[0090] In some possible implementations, the compression ratio of the conductive element 300 is greater than or equal to 30%.
[0091] In this way, the conductive component 300 can be in close contact with the first metal structural component 100 and the second metal structural component 200, resulting in a better electromagnetic shielding effect of the electromagnetic shielding assembly.
[0092] In some possible implementations, the compression ratio of the conductive element 300 is less than or equal to 70%.
[0093] Thus, when the conductive component 300 is an elastic component, it has good resilience, which facilitates close contact between the conductive component 300 and the first metal structural component 100 and the second metal structural component 200, resulting in a better electromagnetic shielding effect of the electromagnetic shielding assembly. Furthermore, it also helps to extend the service life of the conductive component 300, making the electromagnetic shielding effect of the electromagnetic shielding assembly more stable.
[0094] For example, the compression ratio of the conductive element 300 can be greater than or equal to 45% and less than or equal to 55%, for example, the compression ratio of the conductive element 300 can be about 50%.
[0095] In some possible implementations, the conductive element 300 is a conductive cloth, conductive foam, or conductive adhesive strip.
[0096] In this way, the conductive component 300 has good elasticity and can have a high compression ratio, which is conducive to the close contact between the conductive component 300 and the first metal structural component 100 and the second metal structural component 200, resulting in a better electromagnetic shielding effect of the electromagnetic shielding assembly.
[0097] Taking the first metal structural component 100 and the second metal structural component 200 as sheet metal parts with a length of 10cm, the first connecting part 110 and the second connecting part 210 are respectively located on the long side of the first metal structural component 100 and the second metal structural component 200, with d1 being 2cm and d2 being 0.75mm. Taking the conductive component 300 as an example, which is made of conductive foam with a thickness of 1.5mm, after the conductive foam is pressed between the bottom wall 2111 and the plug-in structure 111, the compression ratio of the conductive component 300 is about 50%. The electromagnetic shielding assembly can provide a shielding effectiveness of 30dB in the 5GHz~8GHz frequency band.
[0098] Figure 6 This is a cross-sectional schematic diagram of another electromagnetic shielding component provided in an embodiment of this application.
[0099] like Figure 6 As shown, the second connecting part 210 has a plurality of slots G1 arranged along the width direction of the slot G1, and the first connecting part 110 has a plurality of plug-in structures 111 corresponding to the slots G1. The plug-in structures 111 are inserted into the corresponding slots G1 to form a more complex bend gap channel, which helps to improve the attenuation effect of electromagnetic waves.
[0100] In some examples where the second connection portion 210 has multiple slots G1 arranged along the width direction of the slot G1, a conductive element 300 can be pressed into one of the slots G1.
[0101] Figure 7 This is a cross-sectional schematic diagram of another electromagnetic shielding component provided in an embodiment of this application.
[0102] like Figure 7 As shown, in some examples where the second connecting portion 210 has multiple slots G1 arranged along the width direction of the slot G1, a conductive element 300 can be pressed into each of the multiple slots G1. For example, a conductive element 300 can be pressed into each slot G1.
[0103] Figure 8 This is a cross-sectional schematic diagram of another electromagnetic shielding component provided in an embodiment of this application.
[0104] like Figure 8 As shown, in some examples, the first connecting portion 110 and the second connecting portion 210 can be connected by a reverse snap-fit. Specifically, along the first direction, the third sub-part 212, the fourth sub-part 213, and the second main body portion 220 are located on the same side of the second sub-part 211, and the end of the third sub-part 212 away from the second sub-part 211 is fixedly connected to the second main body portion 220. The first main body portion 120 and the plug-in structure 111 are fixedly connected to the first sub-part 112 on the same side of the first direction, and a snap-fit groove G2 is formed between the plug-in structure 111, the first sub-part 112, and the first main body portion 120, and the fourth sub-part 213 is inserted into the snap-fit groove G2. At this time, the gap formed between the snap-fit groove G2 and the fourth sub-part 213 can play a role in attenuating electromagnetic waves, and the electromagnetic shielding assembly has a good electromagnetic shielding effect.
