Description

Technical Field

[0001] This application belongs to the field of electronic product technology, and specifically relates to an electronic device. Background Technology

[0002] Electrical connections between components in electronic devices typically rely on cables, and because electronic devices integrate a large number of components, they generally contain cables.

[0003] However, the current cable routing methods have shortcomings. Specifically, at least one cable needs to be electrically connected to the circuit board, and these cables are generally fixed to the surface of the circuit board using fasteners. These fasteners occupy some space on the circuit board, thus increasing its size. The increased circuit board size reduces the installation space for other components of the electronic device, thereby affecting the routing of those components. Utility Model Content

[0004] The purpose of this application is to provide an electronic device that can solve the problem of increased circuit board size caused by cable routing in related technologies.

[0005] This application provides an electronic device, including: Circuit board; A cover plate is stacked on a circuit board. The side of the cover plate away from the circuit board has a groove and a through hole. The cable is installed in the cable groove. The cable includes a first cable, which is electrically connected to the circuit board through a through hole.

[0006] In this embodiment, a wire groove is provided on the side of the cover plate opposite to the circuit board. The first cable is inserted into the wire groove and electrically connected to the circuit board through a through hole in the cover plate. This arrangement primarily relies on the wire groove on the cover plate to secure the first cable electrically connected to the circuit board. This eliminates the need for mounting hardware on the circuit board surface to fix the first cable, saving space occupied by mounting hardware and thus reducing the size of the circuit board.

[0009] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0012] Please refer to Figures 1 to 16 As shown, this application embodiment provides an electronic device, including: a circuit board 100, a cover plate 200, and a cable 300. Optionally, the electronic device is, for example, a smartphone, a tablet computer, or an e-book reader.

[0013] The cover plate 200 is stacked on the circuit board 100. The side of the cover plate 200 away from the circuit board 100 may be provided with a wire groove 210, and the cover plate 200 is provided with a through hole 220.

[0014] The cable 300 is fitted into the cable groove 210, and the cable 300 includes a first cable 300a, which is electrically connected to the circuit board 100 through a through hole 220. In some embodiments of this application, the through hole 220 communicates with the cable groove 210 in which the first cable 300a is located.

[0015] Optionally, the cable 300 is a coaxial cable, and there are multiple cables 300 and multiple cable trays 210, with each cable 300 corresponding to a cable tray 210. Furthermore, in this embodiment, the specific number of cables 300 and cable trays 210 is not limited and can be set according to actual needs.

[0016] In this embodiment, a wire groove 210 is provided on the side of the cover plate 200 opposite to the circuit board 100. The first cable 300a is inserted into the wire groove 210 and electrically connected to the circuit board 100 through the through hole 220 on the cover plate 200. In this configuration, the wire groove 210 on the cover plate 200 is primarily used to secure the first cable 300a to the circuit board 100. This eliminates the need for fixing components on the surface of the circuit board 100 to secure the first cable 300a, thus saving space occupied by fixing components and reducing the size of the circuit board 100.

[0017] In another embodiment, reference Figure 2 and Figure 16 As shown, a through groove 240 is provided between the first groove 210a and the second groove 210b, and the first groove 210a and the second groove 210b are connected through the through groove 240.

[0018] By adopting the solution of this embodiment, the material in the area corresponding to the through groove 240 is eliminated, thereby reducing the weight of the cover plate 200. In addition, the first cable groove 210a and the second cable groove 210b are connected through the through groove 240, which allows for more flexible cable routing and the cable 300 can be laid in the area corresponding to the through groove 240, thereby improving the space utilization of the cover plate 200 and helping to reduce the volume of the cover plate 200.

[0019] Further, refer to Figure 2 and Figure 16 As shown, the cables 300 are arranged side by side in the cable tray 210. This arrangement allows for a more compact layout of the cables 300, which also helps to reduce the size of the cover plate 200.

[0020] In other embodiments, each wire groove 210 may also be independent of each other and there is no connection between them.

[0021] In another embodiment, the cover plate 200 is equipped with a speaker. That is, the cover plate 200 is used to house the speaker. This layout is suitable for scenarios where the cable 300 passes through the location of the speaker. This embodiment can reuse the components used to house the speaker to secure the cable 300, thus eliminating the need for an additional cover plate 200, resulting in fewer components in the electronic device.

[0022] In other embodiments, the cover plate 200 may also be without a speaker.

[0023] In one specific implementation, circuit board 100 is a sub-board, and correspondingly, the first cable 300a is used to realize the electrical connection between circuit board 100 and the main board of the electronic device. In this way, the size of the sub-board can be reduced using the solution of this embodiment, which helps to increase the battery capacity of the electronic device, thereby enhancing the market competitiveness of the electronic device.

[0024] Optionally, refer to Figure 1 As shown, cable 300 also includes a second cable 300b, and the electronic device also includes an antenna module 900. The mainboard of the electronic device is electrically connected to the antenna module 900 via the second cable 300b. Furthermore, the antenna module 900 and the sub-board are both located between the housing 700 and the cover plate 200, and the antenna module 900 and the sub-board are arranged sequentially along the width direction of the housing 700, while the mainboard and the sub-board are arranged sequentially along the length direction of the housing 700. The width direction of the housing 700 is, for example, [missing information]. Figure 1 The direction indicated by arrow C in the figure, for example, is the length direction of the housing 700. Figure 1 The direction indicated by the arrow line D in the diagram.

[0025] In another embodiment, reference Figure 3 As shown, the side wall of the cable tray 210 is provided with a first snap-fit ​​part 411 and a second snap-fit ​​part 412. The first snap-fit ​​part 411 and the second snap-fit ​​part 412 are arranged opposite to each other and are both snap-fitted with the cable 300.

[0026] In this embodiment, the first latching part 411 and the second latching part 412 can prevent the cable 300 from coming out of the cable groove 210, thereby improving the stability of the cable 300. Furthermore, both the first latching part 411 and the second latching part 412 are located on the side wall of the cable groove 210 and are integrated into the same component. This facilitates control over the alignment accuracy of the first latching part 411 and the second latching part 412, thereby improving the reliability of the first latching structure 410 when latching the cable 300.

[0027] Optionally, the structure formed by the opposing first latching portion 411 and the second latching portion 412 is defined as a first latching structure 410. For example, at least two first latching structures 410 are provided along the extension direction of the cable groove 210 to further improve the stability of the cable 300. Here, the extension direction of the cable groove 210 is, for example,... Figure 16 The direction indicated by the arrow N in the diagram. Of course, the number of the first snap-fit ​​structure 410 can also be one, depending on the actual needs of the design.

[0028] In other embodiments, the sidewall of the wire groove 210 may not have the first snap-fit ​​part 411 and the second snap-fit ​​part 412.

[0029] In another embodiment, reference Figure 4 As shown, the second cable tray 210b is located near the edge of the cover plate 200. The side wall of the second cable tray 210b is provided with a third snap-fit ​​part 421, and the housing 700 of the electronic device is provided with a fourth snap-fit ​​part 422. The third snap-fit ​​part 421 and the fourth snap-fit ​​part 422 are arranged opposite to each other and are snap-fitted with the second cable 300b.

[0030] In this embodiment, the third latching portion 421 and the fourth latching portion 422 can restrict the second cable 300b from coming out of the second cable groove 210b, thereby improving the stability of the second cable 300b.

[0031] Furthermore, the side wall of the second groove 210b is provided with a third latching part 421, and the housing 700 of the electronic device is provided with a fourth latching part 422. That is, only the third latching part 421 is provided on the cover plate 200. In this way, the size requirements of the cover plate 200 are reduced. When the size of the cover plate 200 is insufficient to provide the fourth latching part 422, the housing 700 can be used to provide the fourth latching part 422.

[0032] Specifically, refer to Figure 2 , Figure 4 as well as Figure 16 As shown, the cable tray 210 includes a first cable tray 210a and a second cable tray 210b. The first cable 300a mentioned above is located in the first cable tray 210a, which communicates with the through hole 220. The second cable 300b mentioned above is located in the second cable tray 210b. The second cable tray 210b is located near the edge of the cover plate 200, and the side wall of the second cable tray 210b near the housing 700 has a notch 280 facing the housing 700. A third latching part 421 is provided on the side wall of the second cable tray 210b away from the housing 700 and corresponding to the notch 280. A fourth latching part 422 corresponding to the third latching part 421 is provided on the housing 700. The third latching part 421 and the fourth latching part 422 are offset in the thickness direction of the cover plate 200, for example, in the thickness direction of the cover plate 200. Figure 9 The direction indicated by the arrow E in the diagram allows for adaptation to the routing of the second cable 300b, which helps improve the stability of the second cable 300b.

[0033] It is understood that the housing 700 of the electronic device can be the main board cover of the electronic device, or it can be the middle frame of the electronic device. Further, the housing 700 may include a partition, with a fourth latching portion 422 disposed on the partition, the partition facing the side wall of the second cable tray 210b. The second cable 300b can be latched between the partition and the side wall of the second cable tray 210b, and its stability is enhanced by the fourth latching portion 422 and the third latching portion 421.

[0034] Optionally, the structure formed by the third snap-fit ​​portion 421 and the fourth snap-fit ​​portion 422 arranged opposite to each other is defined as the second snap-fit ​​structure 420. For example, at least one second snap-fit ​​structure 420 is provided along the extension direction of the second groove 210b. The specific number of second snap-fit ​​structures 420 depends on the actual situation. In this embodiment, there is no limitation on this.

[0035] In other embodiments, the sidewalls of the wire groove 210 may not have the third snap-fit ​​portion 421 and the fourth snap-fit ​​portion 422.

[0036] In another embodiment, reference Figures 6 to 9 As shown, one end of the first cable 300a is provided with a first electrical connector 310, which is electrically connected to the circuit board 100. The electronic device also includes a bracket 500, which is pressed onto the side of the first electrical connector 310 away from the circuit board 100 and covers the through hole 220.

[0037] Under the pressing action of the bracket 500, the electrical connection between the first electrical connector 310 and the circuit board 100 is not easily broken, thereby improving the reliability of the electrical connection between the two.

[0038] Optionally, the circuit board 100 may be provided with a second electrical connector, the first electrical connector 310 being engaged with the second electrical connector, and the bracket 500 being pressed onto the side of the first electrical connector 310 away from the second electrical connector.

[0039] Specifically, the first electrical connector 310 is located inside the through hole 220, and the bracket 500 is, for example, a plate-like structure to increase the mating area between the bracket 500 and the first electrical connector 310.

[0040] In other embodiments, the electronic device may also exclude the bracket 500.

[0041] In another embodiment, reference Figures 6 to 8 As shown, one of the bracket 500 and the cover plate 200 is provided with a positioning post 230, and the other is provided with a positioning hole 510. The positioning post 230 and the positioning hole 510 are positioned and engaged.

[0042] During actual assembly, the position of the bracket 500 can be pre-positioned by the positioning pin 230 and the positioning hole 510, thereby reducing the assembly difficulty of the bracket 500.

[0043] Optionally, the bracket 500 is provided with a positioning hole 510 and the cover plate 200 is provided with a positioning post 230. Of course, it is also possible that the bracket 500 is provided with a positioning post 230 and the cover plate 200 is provided with a positioning hole 510. This application embodiment does not limit this.

[0044] In some embodiments of this application, the bracket 500 covers the through hole 220.

[0045] In other embodiments, the positioning post 230 and the positioning hole 510 may be omitted.

[0046] In another embodiment, the bracket 500 is bonded to the cover plate 200. By bonding the bracket 500 to the cover plate 200, the position of the bracket 500 can be fixed, which simplifies the installation operation of the bracket 500 and reduces the assembly difficulty of the bracket 500.

[0047] Optionally, refer to Figure 8 As shown, the bracket 500 is provided with an adhesive part 540, and the bracket 500 is bonded to the cover plate 200 through the adhesive part 540. The adhesive part 540 is, for example, double-sided adhesive.

[0048] In other embodiments, there may be no adhesive relationship between the bracket 500 and the cover plate 200.

[0049] In one optional embodiment, one of the bracket 500 and the cover plate 200 is provided with a positioning post 230 and the other is provided with a positioning hole 510. The positioning post 230 and the positioning hole 510 are positioned and engaged, while the bracket 500 is bonded to the cover plate 200, so as to make the assembly of the bracket 500 easier.

[0050] In another embodiment, reference Figure 8 As shown, the bracket 500 has an elastic element 530 on the side facing the first electrical connector 310, and the bracket 500 is pressed against the first electrical connector 310 by the elastic element 530.

[0051] After assembly, the elastic element 530 is in a compressed state. In this state, the elastic element 530 can apply a certain pre-pressure to the first electrical connector 310. Under the action of this pre-pressure, the first electrical connector 310 and the circuit board 100 are reliably connected together.

[0052] Furthermore, the elastic element 530 is an insulating element, thus also providing electrical isolation and improving the safety of the electronic device. Specifically, the elastic element 530 is, for example, a foam element.

[0053] In other embodiments, the electronic device may also exclude the elastic element 530.

[0054] In another embodiment, reference Figures 6 to 9 As shown, the electronic device also includes a connector 600, one end of which passes through the bracket 500, the cover plate 200 and the circuit board 100 in sequence, and is connected to the housing 700 of the electronic device.

[0055] With the solution of this embodiment, the probability of separation between the bracket 500 and the first electrical connector 310 is low under the connection action of the connector 600, thereby improving the reliability of the electrical connection between the first electrical connector 310 and the circuit board 100.

[0056] In addition, in this embodiment, the connector 600 passes through the bracket 500, the cover plate 200 and the circuit board 100 at the same time. In this way, the connector 600 can fix the bracket 500 on the one hand, and fix the cover plate 200 and the circuit board 100 on the other hand. This reduces the number of parts used to fix the cover plate 200 and the circuit board 100, thereby simplifying the structure of the electronic device.

[0057] Optionally, the connector 600 may be a threaded connector, for example, which has better connection reliability, thereby improving the stability of the bracket 500.

[0058] Optionally, refer to Figure 7 As shown, the bracket 500 is provided with a clearance hole 520, and one end of the connector 600 passes through the clearance hole 520 to pass through the bracket 500.

[0059] Furthermore, the bracket 500 may be provided with the adhesive portion 540 mentioned above, and one of the bracket 500 and the cover plate 200 may be provided with the positioning post 230 mentioned above, and the other may be provided with the positioning hole 510 mentioned above.

[0060] refer to Figure 6 As shown, during actual assembly, the first electrical connector 310 is first engaged with the second electrical connector on the first circuit board 100. Then, the bracket 500 is installed, allowing the positioning post 230 to engage with the positioning hole 510, and the adhesive part 540 to be bonded to the cover plate 200 to pre-fix the position of the bracket 500. Finally, the connector 600 is installed, completing the overall assembly of the first electrical connector 310 and the bracket 500. During this assembly process, the bracket 500 is pre-bonded to the cover plate 200 via the adhesive part 540. This prevents the bracket 500 from tilting before the connector 600 is installed and reduces shaking during the installation process, thus improving the stability of the bracket 500.

[0061] In other embodiments, the electronic device may not include the connector 600, or the electronic device may include the connector 600, but the connector 600 does not pass through the cover plate 200 and the circuit board 100, that is, the connector 600 does not have the function of fixing the cover plate 200 and the circuit board 100.

[0062] In another embodiment, reference Figure 5 as well as Figures 10 to 15As shown, the electronic device also includes: at least one grounding member 800, which is disposed in the cable trough 210; the grounding member 800 includes a clamping part 820 and a grounding part 810, which are connected; the clamping part 820 clamps the cable 300; and the grounding part 810 is fixed to the cable trough 210.

[0063] In this embodiment, the grounding component 800 is located inside the wire groove 210, which reduces the space occupied outside the wire groove 210, thereby reducing the size of the electronic device.

[0064] Furthermore, the clamping part 820 of the grounding component 800 clamps the cable 300, so that the cable 300 and the grounding component 800 are reliably connected together and are not easily separated.

[0065] It should be noted that the number of grounding components 800 can be arbitrary, and the specific number depends on the actual situation. This application embodiment does not impose any restrictions on this.

[0066] In other embodiments, at least a portion of the grounding element 800 may also be located outside the cover plate 200.

[0067] In another embodiment, reference Figure 5 and Figure 10 As shown, the clamping part 820 and the grounding part 810 together form a first groove 850. The opening of the first groove 850 faces away from the cover plate 200. Specifically, the opening of the first groove 850 faces away from the bottom wall of the wire groove 210. At least a portion of the cable 300 is clamped in the first groove 850, and the grounding part 810 is fixed to the bottom wall of the wire groove 210.

[0068] Using the scheme of this embodiment, the cable 300 is sequentially inserted into the first groove 850 through the groove opening of the wire groove 210 and the groove opening of the first groove 850, thereby assembling the cable 300 and the grounding component 800. Conversely, the cable 300 is sequentially removed from the wire groove 210 through the groove opening of the first groove 850 and the groove opening of the wire groove 210, thereby disassembling the cable 300 and the grounding component 800. In this way, the disassembly and assembly of the cable 300 are more convenient, thereby reducing the difficulty of replacing the cable 300.

[0069] Optionally, the clamping part 820 has a claw-like structure, and the wire groove 210 includes a first groove segment 211 and a second groove segment 212 connected sequentially along its own extending direction. The clamping part 820 is located within the first groove segment 211, and the width of the first groove segment 211 is greater than the width of the clamping part 820, so as to form a deformation space 250 between the two. The width direction of the first groove segment 211 is, for example, as follows: Figure 5 The direction indicated by the arrow M in the diagram, and the extension direction of the groove 210 here, for example, is... Figure 5The direction indicated by the arrow line L in the diagram. Due to the existence of the deformation space 250, during the process of the cable 300 entering the first groove 850, the clamping part 820 can slightly expand in the width direction of the first groove segment 211, which can reduce the difficulty of assembling and disassembling the cable 300.

[0070] Specifically, refer to Figure 10 As shown, the clamping part 820 includes a first clamping claw 822 and a second clamping claw 823. The first clamping claw 822 and the second clamping claw 823 are arranged opposite to each other in the width direction of the first groove 211. One end of the first clamping claw 822 and the second clamping claw 823 are connected to the grounding part 810. The first clamping claw 822 and the second clamping claw 823 and the grounding part 810 together form a first groove 850.

[0071] Optionally, refer to Figure 5 and Figure 10 As shown, the grounding portion 810 has a plate-like structure. The length of the grounding portion 810 along the extension direction of the groove 210 is greater than the length of the clamping portion 820 along the extension direction of the groove 210. A portion of the grounding portion 810 is located within the first groove segment 211 and forms a first groove 850 with the clamping portion 820. Another portion of the grounding portion 810 is located within the second groove segment 212 and engages with the second groove segment 212 at its upper limit in the width direction of the second groove segment 212. The width direction of the second groove segment 212 is, for example, the same as the width direction of the first groove segment 211. With this arrangement, the movement of the grounding portion 810 in the width direction of the second groove segment 212 is restricted, thereby improving the stability of the grounding portion 810.

[0072] In another embodiment, the wire groove 210 and the grounding member 800 are engaged at the upper limit of the extension direction of the wire groove 210, where the extension direction of the wire groove 210 is, for example, also... Figure 5 The direction indicated by the arrow line L in the diagram. With this configuration, the movement of the grounding element 800 in the extension direction of the groove 210 is restricted, thereby improving the stability of the grounding element 800.

[0073] Specifically, refer to Figure 5 As shown, the wire trough 210 is provided with a first step portion 213 and a second step portion 214. In the extension direction of the wire trough 210, the opposite ends of the grounding member 800 are respectively limited to the first step portion 213 and the second step portion 214 to achieve the upper limit cooperation between the wire trough 210 and the grounding member 800 in the extension direction of the wire trough 210.

[0074] In another embodiment, reference Figures 11 to 15As shown, the clamping part 820 has a second groove 821, the opening of the second groove 821 facing the cover plate 200. Specifically, the opening of the second groove 821 is set facing the bottom wall of the wire trough 210. At least a portion of the cable 300 is clamped in the second groove 821. The side wall of the wire trough 210 is provided with a snap-fit ​​groove 290, and the grounding part 810 is fixed in the snap-fit ​​groove 290.

[0075] In this embodiment, the opening of the second groove 821 is positioned facing the bottom wall of the wire groove 210. In this way, the bottom wall of the wire groove 210 can prevent the cable 300 from coming out of the second groove 821, thereby improving the stability of the cable 300.

[0076] Optionally, refer to Figure 11 As shown, the clamping part 820 has a semi-annular structure, and the grounding part 810 has an ear-shaped structure. There are two grounding parts 810, with grounding parts 810 at both ends of the clamping part 820. Correspondingly, each of the two opposite side walls of the wire groove 210 has a snap-fit ​​groove 290, and the two clamping parts 820 are respectively located in the two snap-fit ​​grooves 290. In this way, the two clamping parts 820 share the force, thereby preventing excessive local stress in the grounding component 800 and extending the service life of the grounding component 800.

[0077] Optionally, a portion of the sidewall of the wire groove 210 is recessed to form a snap-fit ​​groove 290.

[0078] Optionally, refer to Figure 14 As shown, one end of the grounding part 810 is connected to the clamping part 820, and the other end is folded 180 degrees to form a folded part 830. In this configuration, the folded part 830 occupies a portion of the space in the snap-fit ​​groove 290, thereby making the end of the grounding part 810 away from the clamping part 820 fit more tightly with the snap-fit ​​groove 290, thus improving the stability of the grounding component 800.

[0079] It should also be noted that in other embodiments, other components may be additionally connected to the end of the grounding portion 810 away from the clamping portion 820 to make the fit between the end of the grounding portion 810 away from the clamping portion 820 and the snap-fit ​​groove 290 more tight. Additionally, refer to... Figure 11 As shown, the end of the grounding portion 810 away from the clamping portion 820 may not be folded.

[0080] In one alternative embodiment, reference is made to... Figure 15 As shown, the grounding component 800 is, for example, an elastic structure, and the cover plate 200 is, for example, provided with an assembly chamfer 270. The assembly chamfer 270 is guided and engaged with the grounding component 800 so as to fix the grounding part 810 in the snap-fit ​​groove 290.

[0081] During actual assembly, the grounding component 800 undergoes elastic deformation to avoid the cover plate 200, thereby allowing the grounding part 810 to be placed into the snap-fit ​​groove 290. After installation, the grounding component 800 returns to its initial shape, thus ensuring that the grounding part 810 is reliably installed in the snap-fit ​​groove 290.

[0082] In another embodiment, reference Figures 13 to 15 As shown, a conductive insert 260 is provided inside the cover plate 200, and the grounding part 810 is electrically connected to the conductive insert 260.

[0083] In this embodiment, the conductive insert 260 is located inside the cover plate 200, which reduces the space occupied outside the cover plate 200, thereby helping to reduce the size of the electronic device.

[0084] Furthermore, to enhance the strength of the cover plate 200, the cover plate 200 itself may be embedded with a conductive insert 260. In this case, the conductive insert 260 of the cover plate 200 itself can be directly connected to the grounding part 810 to achieve grounding of the grounding part 810. This grounding method directly reuses the conductive insert 260 of the cover plate 200 itself, thereby simplifying the structure of the electronic device.

[0085] In other embodiments, the cover plate 200 may also be without the conductive insert 260. In this case, the electronic device may include a conductive part located outside the cover plate 200, and the grounding part 810 is grounded through the conductive part.

[0086] In one alternative embodiment, the conductive insert 260 forms the bottom wall of the groove 210. With this arrangement, a portion of the conductive insert 260 is exposed, which facilitates the connection of the grounding member 800 to the conductive insert 260.

[0087] Optionally, refer to Figure 5 As shown, the grounding part 810 is directly fixed to the conductive insert 260, thereby fixing the grounding part 810 to the bottom wall of the wire groove 210 and simultaneously achieving electrical connection between the grounding part 810 and the conductive insert 260. Specifically, the grounding part 810 is, for example, soldered to the conductive insert 260.

[0088] Optionally, the aforementioned snap-fit ​​slot 290 has an opening facing the conductive insert 260, and the grounding portion 810 is snapped into the snap-fit ​​slot 290 and makes conductive contact with the conductive insert 260. With this configuration, the cable 300, for example along... Figure 13 The path indicated by the middle arrow or Figure 14 The path indicated by the middle arrow is grounded. Additionally, in this configuration, cable 300 can, for example, directly contact the conductive insert 260, allowing cable 300 to... Figure 13 and Figure 14The path indicated by the middle arrow is grounded, meaning that cable 300 can be grounded sequentially through grounding component 800 and conductive insert 260. On the other hand, cable 300 can be grounded directly through conductive insert 260, thereby improving the grounding effect of cable 300.

[0089] Optionally, when the grounding portion 810 has a folded portion 830, the folded portion 830 is disposed away from the conductive insert 260.

[0090] It should also be noted that the conductive insert 260 and the grounding element 800 in this embodiment are two separate components. Therefore, the material of the grounding element 800 is not limited to the material of the conductive insert 260, thus allowing for greater design flexibility for both the grounding element 800 and the conductive insert 260. Specifically, the grounding element 800 can be, for example, a metal component, or more specifically, a steel component.

[0091] In one alternative embodiment, reference is made to... Figure 5 As shown, the cable 300 is provided with a grounding ring 320, which is sleeved on the cable 300 and electrically connected to the cable 300. The grounding ring 320 makes conductive contact with the grounding component 800 and / or the conductive insert 260 to achieve grounding of the cable 300.

[0092] Further, refer to Figure 11 As shown, the clamping part 820 mentioned above, for example, has a grounding protrusion 840. The grounding protrusion 840 makes conductive contact with the grounding ring 320, thereby achieving an electrical connection between the clamping part 820 and the cable 300. Compared to other positions of the clamping part 820, the grounding protrusion 840 is closer to the grounding ring 320, and it is more tightly connected to the grounding ring 320, thereby achieving good grounding of the cable 300.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
