[0017] In the above structure, during the assembly of the terminal equipment, the support part can serve as a fulcrum, which is conducive to the second conductive part abutting against the first conductive part and to forming an electrical connection structure that can be stably connected.
[0018] In conjunction with the first aspect, in some possible embodiments of this application, the first surface is provided with a convex hull for abutting against the second surface; or, the second surface is provided with a convex hull for abutting against the first surface.
[0019] In the above structure, the convex hull is used to increase the effective contact area and contact pressure of the first and second surfaces, which helps to reduce contact resistance and thus helps to improve the RSE problem.

[0050] Detailed Implementation
[0051] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this application; the described embodiments are merely some, not all, of the embodiments described in this application.
[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes all and any combination of one or more of the associated listed items.
[0053] In the various embodiments of this application, for ease of description and not limitation, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, whether direct or indirect. Terms such as "upper," "lower," "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.
[0054] Please see Figure 1 , Figure 1 This application provides an overall structural schematic diagram of a terminal device 100 according to an embodiment of the present application. Figure 1 The terminal device 100 shown is a mobile phone. In other embodiments, the terminal device 100 may also include, but is not limited to, electronic products such as tablet computers, laptops, cameras, and wearable devices. Wearable devices include, but are not limited to, smart bracelets, smartwatches, and smart glasses.
[0055] Please see Figure 2 and Figure 3 , Figure 2 A schematic diagram of the structure of some components of the terminal device 100 provided for related technologies. Figure 3 for Figure 2 A schematic diagram of the front structure of some components of the terminal device 100 shown.
[0056] The terminal device 100 includes multiple components. For example, the terminal device 100 may include a grounding member 10, a supporting member 20, a bracket 30, and a structural member 40. The grounding member 10 is used for grounding. One end of the supporting member 20 is fixed to the grounding member 10, one end of the bracket 30 is fixed to the structural member 40, and the other end of the bracket 30 abuts against the end of the supporting member 20. The supporting member 20 is used to limit the bracket 30 to prevent the bracket 30 from tilting.
[0057] To ensure the structural strength of the supporting member 20 and the bracket 30, the materials of the supporting member 20 and the bracket 30 are usually metals or metal alloys, such as copper, iron, aluminum, stainless steel, etc. Metals or metal alloys have electrical conductivity. The surface of the bracket 30 that contacts the supporting member 20 is provided with insulating varnish 292' to facilitate an insulated connection between the bracket 30 and the supporting member 20.
[0058] In actual products, the end of the retainer 20 is a cross-section with an uneven structure, typically containing burrs 29'. When the bracket 30 abuts against the end of the retainer 20, the burrs 29' can easily pierce the insulating varnish 292'. After piercing the insulating varnish 292', the burrs 29' become electrically connected to the bracket 30, making it difficult to achieve complete insulation between the bracket 30 and the retainer 20. Furthermore, due to limitations in actual manufacturing processes, the edge area of the bracket 30 (e.g., within a 0.1mm radius) may contain areas not covered by the insulating varnish 292', potentially leading to areas of electrical connection between the bracket 30 and the retainer 20. In other words, there is a "partially connected" phenomenon between the bracket 30 and the abutment 20, resulting in a high contact resistance between them. This can easily lead to failure in Radiated Spurious Emissions (RSE) testing during factory inspection of the terminal equipment 100. Furthermore, after the burr 29' pierces the insulating varnish 292' and becomes electrically connected to the bracket 30, a small portion of electrons tunnel through the varnish 292', generating a high third harmonic. This nonlinear electrical connection causes RSE problems, resulting in a high third harmonic, with far-field radiation levels (H3) even greater than or equal to 45 dBm. The terminal equipment 100 exhibits poor consistency, posing a potential threat to its stability and performance.
[0059] Please see Figures 4 to 12 , Figures 4 to 12 These are schematic front views of some components of a terminal device 100a (or 100b, 100c) provided in some embodiments of this application. The terminal device 100a (or 100b, 100c) provided in the embodiments of this application can improve the aforementioned RSE problem.
[0060] Third harmonic current I at the contact point of the electrical connection 3rd Proportional to contact resistance R cThe third harmonic current I is the cube of the fundamental current amplitude I0. 3rd With contact resistance R c The relationship between the fundamental current amplitude I0 and the fundamental current amplitude can be approximated as:
[0061] I 3rd ∝R c ·I0 3
[0062] In some implementations, this can be achieved by reducing the contact resistance R. c And / or reduce the fundamental current amplitude I0 to reduce the third harmonic current, thereby improving the RSE problem. When two components are in a "closed-to-close" connection, specifically, for example, the contact resistance R between the two components... c The resistance is 4.5Ω, and the fundamental current amplitude I0 is 1A. When the contact resistance R... c After reducing the Ω to 0.45Ω, while keeping the fundamental current amplitude I0 unchanged, the third harmonic current I... 3rd The fundamental frequency power can be reduced accordingly; for example, it can be reduced by 20 dB. When the fundamental current amplitude I0 is reduced, the third harmonic current I... 3rd The power can also be reduced accordingly; the fundamental power can be reduced by 30dB to 60dB (according to the approximate formula for the third harmonic current). 3f0 =a3·I f0 3 +a5·I f0 5 (Calculated by +……). In Figures 4 to 12 In the illustrated embodiment, by reducing the contact resistance R c This reduces the third harmonic current, thereby improving the RSE problem.
[0063] Please see Figures 4 to 12 The terminal device 100a (or 100b, 100c) may include a grounding component 10, a supporting component 20a, a bracket 30, and a structural component 40. The grounding component 10 is used for grounding and may be a shield. The supporting component 20a and the grounding component 10 are fixed to each other, and the bracket 30 and the structural component 40 are fixed to each other. The bracket 30 and the supporting component 20a are electrically connected. Since both the supporting component 20a and the bracket 30 can be grounded through the grounding component 10, the electrical connection between the supporting component 20a and the bracket 30 will not affect the original circuit design of the terminal device 100a (or 100b, 100c). The grounding component 10... Figure 4 It is shown in the figure, but not in other figures.
[0064] It should be noted that, unless otherwise specified in this application, "mutual fixation" means that two or more components are connected or combined with each other in some way to maintain the stability of their relative position or state. Mutual fixation includes direct fixation and indirect fixation. For example, two components are directly fixed by welding, riveting or other methods, or two components are indirectly fixed by bolts, nuts or other methods, or the two components can be an integral structure.
[0065] Please see Figures 4 to 10 The abutment member 20a may include a first fixing part 21, a first connecting part 23, and a first conducting part 25a that are fixed to each other, and the abutment member 20a may be an integral structure. The first connecting part 23 connects the first fixing part 21 and the first conducting part 25a, and the first fixing part 21 and the first conducting part 25a are respectively connected to opposite ends of the first connecting part 23. The first fixing part 21 and the first conducting part 25a are both bent relative to the first connecting part 23, and the first fixing part 21 and the first conducting part 25a may be located on the same side of the first connecting part 23 or on opposite sides of the first connecting part 23. Figure 4 In the embodiment shown, the first fixing part 21 and the first conducting part 25a are located on the same side of the first connecting part 23, and the cross-section of the abutment 20a along one direction is approximately C-shaped.
[0066] The first fixing part 21 is fixed to the grounding member 10, and the first fixing part 21 and the grounding member 10 are electrically connected. The first conductive part 25a includes a first surface 252, which is used for electrical connection with the bracket 30. In this embodiment, the first fixing part 21 is welded to the surface of the grounding member 10; the first surface 252 is the surface of the first conductive part 25a facing away from the first fixing part 21.
[0067] The bracket 30 may include a second fixing part 31, a second connecting part 33, and a second conducting part 35 that are fixed to each other. The bracket 30 may be an integral structure. The second connecting part 33 connects the second fixing part 31 and the second conducting part 35, and the second fixing part 31 and the second conducting part 35 are respectively connected to opposite ends of the second connecting part 33. Both the second fixing part 31 and the second conducting part 35 are bent relative to the second connecting part 33. The second fixing part 31 and the second conducting part 35 may be located on the same side of the second connecting part 33 or on opposite sides of the second connecting part 33. Figure 4 In the embodiment shown, the second fixing part 31 and the second conducting part 35 are located on opposite sides of the second connecting part 33, and the cross-section of the bracket 30 along one direction is approximately Z-shaped.
[0068] The second fixing part 31 is fixed to the structural member 40. In this embodiment, the second fixing part 31 and the structural member 40 can be fixed by a fixing member (not shown). The structural member 40 can be a camera, a board-to-board connector (BTB connector), etc. The second connecting part 33 and the first connecting part 23 can be substantially parallel, and the abutment member 20a is located on the side of the second conductive part 35 where the second connecting part 33 is located. The second conductive part 35 includes a second surface 352, which is used for electrical connection with the first surface 252 of the abutment member 20a. In this embodiment, the second surface 352 is the surface of the second conductive part 35 near the side where the second fixing part 31 is located.
[0069] exist Figures 4 to 10 In the illustrated embodiment, the first surface 252 and / or the second surface 352 are curved surfaces, meaning at least one of the first surface 252 and the second surface 352 is curved. Compared to a cross-sectional connection, this embodiment uses a smoothly transitioned curved surface for connection, providing sufficient effective contact area between the first surface 252 and the second surface 352, which helps reduce the contact resistance R between the first conductive portion 25a and the second conductive portion 35. c This improves the RSE problem; furthermore, the curved surface can abut against the other surface, increasing the contact pressure between the first conductive part 25a and the second conductive part 35, thereby helping to further reduce the contact resistance R between the first conductive part 25a and the second conductive part 35. c This will help to further improve the RSE problem.
[0070] exist Figure 4 In the embodiment shown, the first conductive part 25a is bent and protrudes toward the second conductive part 35. The first surface 252 is arc-shaped and convex. The second surface 352 is flat and abuts against the first surface 252.
[0071] exist Figure 5 In the illustrated embodiment, both the first conductive portion 25a and the second conductive portion 35 are bent, and both the first surface 252 and the second surface 352 are arc-shaped and convex. The protrusion directions of the first conductive portion 25a and the second conductive portion 35 are different. In this embodiment, the first conductive portion 25a protrudes in a direction away from the second connecting portion 33, and the second conductive portion 35 protrudes in a direction towards the first conductive portion 25a. Both the first conductive portion 25a and the second conductive portion 35 have a certain deformation space, which is beneficial to further increase the contact pressure, thereby helping to further reduce the contact resistance R between the first conductive portion 25a and the second conductive portion 35. c This will help to further improve the RSE problem.
[0072] exist Figure 6 In the illustrated embodiment, both the first conductive portion 25a and the second conductive portion 35 are bent, and both the first surface 252 and the second surface 352 are arc surfaces, with the first surface 252 being concave and the second surface 352 being convex. The first conductive portion 25a and the second conductive portion 35 protrude in the same direction. In this embodiment, both the first conductive portion 25a and the second conductive portion 35 protrude in a direction away from the structural member 40. In other embodiments, both the first conductive portion 25a and the second conductive portion 35 protrude in other directions, such as away from the grounding member 10, away from the first fixing portion 21, or towards the first fixing portion 21; in other embodiments, the first surface 252 may also be convex and the second surface 352 concave.
[0073] exist Figure 7 In the illustrated embodiment, both the first conductive portion 25a and the second conductive portion 35 are bent, and there are multiple bends in the first conductive portion 25a and the second conductive portion 35. This increases the effective contact area of the first conductive portion 25a and the second conductive portion 35 and helps to reduce the contact resistance R. c This will help to further improve the RSE problem.
[0074] exist Figure 8 and Figure 9 In the illustrated embodiment, the bracket 30 further includes a support portion 37, which is disposed on the second fixing portion 31, and the support portion 37 is surface-connected to the structural member 40. During the assembly of the terminal device 100a, the abutment 20a and the grounding member 10 are first fixed relative to each other, and the position of the structural member 40 is also fixed relative to each other; then, the second conductive portion 35 of the bracket 30 passes through the gap between the abutment 20a and the structural member 40, and the support portion 37 contacts the structural member 40; the second fixing portion 31 of the bracket 30 is pressed towards the structural member 40, with the bracket 30 acting as a spring arm and the support portion 37 acting as a fulcrum, and the second conductive portion 35 abutting against the first conductive portion 25a in a direction opposite to the pressing direction F; finally, the bracket 30 and the structural member 40 are fixed, thereby forming an electrical connection structure that can be stably connected.
[0075] Please refer to it again. Figure 8 and Figure 9The first surface 252 or the second surface 352 is provided with a protrusion 27. Taking the second surface 352 as an example, the number of protrusions 27 can be multiple, and the multiple protrusions 27 are distributed on the second surface 352. The protrusions 27 protrude towards the first surface 252 relative to the second surface 352, and the protrusions 27 are used to abut against the first surface 252. When the first surface 252 is provided with a protrusion 27, the protrusions 27 protrude towards the second surface 352 relative to the first surface 252, and the protrusions 27 are used to abut against the second surface 352. The protrusions 27 are used to increase the effective contact area and contact pressure of the first surface 252 and the second surface 352, which helps to reduce the contact resistance R. c This will help improve the RSE problem.
[0076] Please see Figure 10 ,and Figures 4 to 9 The embodiment shown differs from the one described above in that... Figure 10 In the illustrated embodiment, both the first surface 252 and the second surface 352 are planar. Compared to a cross-sectional connection, this embodiment increases the effective contact area between the first surface 252 and the second surface 352, which helps to reduce the contact resistance R. c This helps to improve the RSE problem. When both the first surface 252 and the second surface 352 are planar, structures such as the support portion 37 and the convex hull 27 can also be provided accordingly.

The first connecting part 23 connects the first fixing part 21 and the first conducting part 25, and the first fixing part 21 and the first conducting part 25 are respectively connected to opposite ends of the first connecting part 23. The first fixing part 21 is bent relative to the first connecting part 23, while the first conducting part 25 is not bent relative to the first connecting part 23, and the cross-section of the abutment 20 along one direction is approximately L-shaped. The structure of the bracket 30 can be referred to Figures 4 to 10 The example shown.
[0078] The first conductive portion 25 includes an end face 254, which is the surface of the first conductive portion 25 facing away from the first connecting portion 23. The end face 254 may have burrs 29' formed on it. The terminal device 100b also includes a first conductive element 51b, which connects the end face 254 of the first conductive portion 25 and the second surface 352 of the second conductive portion 35.
[0079] The first conductive element 51b can be at least one of conductive paste, conductive adhesive, and conductive cloth. The conductive paste can be formed by soldering, for example, solder paste, silver paste, etc. The conductive adhesive or conductive cloth can be bonded between the end face 254 of the first conductive portion 25 and the second surface 352 of the second conductive portion 35. By providing the first conductive element 51b between the first conductive portion 25 and the second conductive portion 35, even if burrs 29' are formed on the end face 254, the first conductive element 51b can fill the gap between the end face 254 of the first conductive portion 25 and the second surface 352 of the second conductive portion 35, which helps to improve the electrical connection reliability of the first conductive portion 25 and the second conductive portion 35, thereby helping to reduce the contact resistance R between the first conductive portion 25 and the second conductive portion 35. c This will help improve the RSE problem.
[0080] Please see Figure 12 Alternatively, the retaining member 20 and the bracket 30 can be fixed by setting fastener 55c. Fastener 55c connects the retaining member 20 and the bracket 30, and serves to secure the retaining member 20 and the bracket 30. This improves the electrical connection reliability of the first conductive part 25 and the second conductive part 35, thereby reducing the contact resistance R between the first conductive part 25 and the second conductive part 35. c This will help improve the RSE problem.
[0081] In this embodiment, the fastener 55c may be arranged in a ring around the first connecting portion 23 and the second connecting portion 33 to secure the abutment 20 and the bracket 30. In other embodiments, the fastener 55c may also pass through the first connecting portion 23 of the abutment 20 and the second connecting portion 33 of the bracket 30 to secure the abutment 20 and the bracket 30.
[0082] In some related technologies, a snap-fit connector is used to securely connect two electrical connectors. However, this snap-fit connection method involves complex structures, requiring a high degree of matching between the snap-fit's structure and the structure of the connection area. Otherwise, assembly tolerances can easily exist between the snap-fit and the electrical connector, reducing the reliability of the electrical connection. In other related technologies, the metal contacts of the circuit board and antenna often experience friction, leading to oxide buildup on their surfaces and affecting contact reliability. Springs are used to connect the circuit board and the housing to prevent friction between the circuit board and the metal contacts. Still other related technologies use a snap-fit electrical connector to connect the two electrical connectors. All of the above related technologies require the addition of extra components to electrically connect the two electrical connectors. Figures 4 to 11 In the illustrated embodiment, the reliability of the electrical connection between the first conductive part 25 and the second conductive part 35 can be increased without adding additional components. Figure 12Although the embodiment shown adds a fastener 55c, the structure of the fastener 55c is simple and is not directly related to the structure of the first conductive part 25 and the second conductive part 35, and will not reduce the electrical connection reliability of the electrical connection area.
[0083] Please see Figures 13 to 18 as well as Figure 20 , Figures 13 to 18 as well as Figure 20 This is a front structural schematic diagram of some components of the terminal device 100d (or 100e, 100f) provided in other embodiments of this application. The terminal device 100d (or 100e, 100f) provided in the embodiments of this application increases a stable conductive area to achieve a current shunting effect, which is equivalent to reducing the fundamental current amplitude I0, thereby reducing the third harmonic current and improving the RSE problem.
[0084] Terminal equipment 100d (or 100e, 100f) includes a grounding component 10, a supporting component 20, a bracket 30, and a structural component 40. For details on the structure of the grounding component 10, the supporting component 20, the bracket 30, and the structural component 40, please refer to [reference needed]. Figures 4 to 12 The embodiment shown is intended to clearly illustrate the relationship between the support member 20 and the bracket 30. Figures 13 to 18 as well as Figure 20 Grounding component 10 and structural component 40 are not shown in the attached diagrams. For details regarding grounding component 10 and structural component 40, please refer to [reference needed]. Figure 4 .
[0085] and Figures 4 to 12 The embodiment shown differs from the one described above in that... Figures 13 to 18 as well as Figure 20 In the illustrated embodiment, the terminal device 100d (or 100e, 100f) may further include a second conductive element 53, which is electrically connected to the support element 20 and the bracket 30, thereby serving as a current shunt. It is understood that the second conductive element 53 is made of a conductive material. Specifically, the areas where the first conductive portion 25 and the second conductive portion 35 are electrically connected (see details...) Figures 4 to 12 The structure of the first conductive area is used as the first conductive area, and the area where the second conductive element 53 connects the support 20 and the bracket 30 is used as the second conductive area. Increasing the second conductive area can reduce the current in the first conductive area (i.e., reduce the fundamental current amplitude I0) so as to play a shunting role and thus improve the RSE problem.
[0086] exist Figure 13In the illustrated embodiment, the second conductive element 53 can be made of conductive paste, conductive adhesive, conductive cloth, conductive foam, or conductive silicone, etc. The second conductive element 53 connects the first connecting part 23 and the second connecting part 33. When the second conductive element 53 is conductive paste, conductive adhesive, or conductive cloth, the support member 20 and the bracket 30 are non-separable; that is, if the support member 20 and the bracket 30 are separated and the terminal device 100d is reassembled, the second conductive element 53 can no longer provide electrical connection. When the second conductive element 53 is conductive foam or conductive silicone, the support member 20 and the bracket 30 are separable; that is, if the support member 20 and the bracket 30 are separated and the terminal device 100d is reassembled, the second conductive element 53 can still provide electrical connection.
[0087] exist Figures 14 to 17 In the illustrated embodiment, the second conductive element 53 can be a first spring 531e, which can deform during the assembly of the terminal device 100e. The first spring 531e can include a first end 5312e and a second end 5314e, which are opposite ends of the first spring 531e. The first end 5312e is fixed to one of the abutment 20 and the bracket 30, and the second end 5314e abuts against the other of the abutment 20 and the bracket 30.
[0088] Please see Figure 14 and Figure 15 Taking the first spring clip 531e fixed to the abutment 20 as an example, please refer to the following for details. Figure 14 The first end 5312e of the first spring piece 531e is roughly plate-shaped and is fixed to the surface of the first fixing part 21 of the abutment member 20. The second end 5314e of the first spring piece 531e is roughly bent, that is, the cross section of the second end 5314e is roughly arc-shaped. The second end 5314e is raised relative to the first connecting part 23 toward the bracket 30 and abuts against the second connecting part 33 to realize the electrical connection between the abutment member 20 and the bracket 30.
[0089] The second end 5314e has an opening after bending. To prevent scraping during the assembly of the abutment 20, the first spring 531e, and the bracket 30, the direction of movement of the abutment 20 or the bracket 30 is related to the direction of the opening of the second end 5314e. For example, when the abutment 20 with the first spring 531e fixed thereon acts as a static component and the bracket 30 acts as a dynamic component, the bracket 30 is moved along the first direction L1 so that the second connecting part 33 and the second end 5314e of the first spring 531e come into contact, and the second conductive part 35 and the first conductive part 25 come into contact; then the bracket 30 is acted on along the second direction L2, and the second end 5314e deforms and abuts against the second connecting part 33 to complete the assembly process.
[0090] Please see Figure 15 The first end 5312e of the first spring piece 531e is generally plate-shaped and is fixed to the surface of the first connecting part 23 of the abutment member 20; the second end 5314e of the first spring piece 531e is generally bent and is raised towards the bracket 30 relative to the first connecting part 23 and abuts against the second connecting part 33 to realize the electrical connection between the abutment member 20 and the bracket 30.
[0091] During the assembly of terminal device 100e, when the abutment 20 with the first spring piece 531e fixed thereon acts as a dynamic component and the bracket 30 acts as a static component, the abutment 20 is moved along the first direction L1 so that the second end 5314e of the first spring piece 531e contacts the second connecting part 33 of the bracket 30, and the first conductive part 25 and the second conductive part 35 contact each other. Then, the abutment 20 is acted on along the second direction L2, and the second end 5314e deforms and abuts against the second connecting part 33 to complete the assembly process.
[0092] Please see Figure 16 It is understood that in other embodiments, the first spring piece 531e can also be fixed to the bracket 30, that is, the first end 5312e of the first spring piece 531e is fixed to the surface of the second fixing part 31 of the bracket 30, and the second end 5314e is raised relative to the second connecting part 33 toward the abutment 20 and abuts against the first connecting part 23, so as to realize the electrical connection between the abutment 20 and the bracket 30.
[0093] Please see Figure 17 In some embodiments, the first end 5312e of the first spring piece 531e is fixed to the surface of the second connecting portion 33, and the second end 5314e is raised relative to the second connecting portion 33 toward the abutment 20 and abuts against the first connecting portion 23 to realize the electrical connection between the abutment 20 and the bracket 30.
[0094] exist Figure 18 In the illustrated embodiment, the second conductive element 53 can be a second spring 532f, which can deform during the assembly of the terminal device 100f. The second spring 532f may include a first end 5322f, a second end 5324f, and an intermediate segment 5326f. The first end 5322f and the second end 5324f are opposite ends of the second spring 532f, and the intermediate segment 5326f is located between the first end 5322f and the second end 5324f. The first end 5322f is fixed to one of the first connecting portion 23 and the second connecting portion 33, the second end 5324f is movably connected to one of the first connecting portion 23 and the second connecting portion 33, and the intermediate segment 5326f abuts against the other of the first connecting portion 23 and the second connecting portion 33.
[0095] In this embodiment, the second spring piece 532f is located between the first connecting portion 23 and the second connecting portion 33. The first end 5322f is fixed to the bracket 30, and the second end 5324f is movably connected to the bracket 30. The middle section 5326f abuts against the abutment member 20. Specifically, the first end 5322f is fixed to the second connecting portion 33, the second end 5324f is connected to the surface of the second connecting portion 33 and can move relative to the surface of the second connecting portion 33; the middle section 5326f is bent and protrudes towards the first connecting portion 23, and the middle section 5326f is used to abut against the first connecting portion 23 to realize the electrical connection between the abutment member 20 and the bracket 30.
[0096] Please see Figure 19 , Figure 19 To make Figure 18 The diagram shows the structure of the bracket 30. The second spring 532f and the bracket 30 can be an integral structure. For example, during the manufacturing process of the bracket 30, an elastic part 5328f is formed on the surface of the bracket 30. The elastic part 5328f and the bracket 30 are an integral structure. One end of the elastic part 5328f is connected to the second connecting part 33, and the other end is disconnected from the bracket 30. The middle area of the elastic part 5328f is stretched in a direction away from the second connecting part 33 and bent. At this time, the disconnected end of the elastic part 5328f and the bracket 30 moves relative to the bracket 30.
[0097] When the second conductive element 53 is the first spring 531e or the second spring 532f, the support 20 and the bracket 30 are separable. If the support 20 and the bracket 30 are separated and the terminal device 100f is reassembled, the second conductive element 53 can still play the role of electrical connection.
[0098] Please see Figure 20 The first end 5322f of the second spring piece 532f is fixed to the abutment 20, and the second end 5324f is movably connected to the abutment 20; the middle section 5326f abuts against the bracket 30. For detailed structure, please refer to [reference needed]. Figure 18 The example shown.
[0099] In some embodiments, depending on the electrical connection performance requirements, the area of the first connection portion 23 or the second connection portion 33 used for electrical connection may be plated with a high conductivity (e.g., σ>10). 7 Metals with a conductivity of S / m or coated with conductive adhesive are used to increase conductivity.
[0100] It should be noted that, Figures 13 to 18 as well as Figure 20 Improving the technical characteristics corresponding to the RSE problem by reducing the fundamental current amplitude I0, and Figures 4 to 12 The embodiment shown employs a method to reduce contact resistance R. cThe methods used to improve the technical characteristics corresponding to the RSE problem are not contradictory; therefore, they are applicable to... Figures 4 to 12 The technical features of the first conductive part 25 and the second conductive part 35 shown can also be further applied to Figures 13 to 18 as well as Figure 20 The embodiment shown is equivalent to simultaneously increasing the connection reliability between the support member 20 and the bracket 30 to reduce the contact resistance R. c Furthermore, by increasing the conductive area to shunt the current, the amplitude of the fundamental current I0 is reduced, which is beneficial to further improve the RSE problem.
[0101] Please see Figure 21 , Figure 21 This is a front structural schematic diagram of some components of the terminal device 100g provided in some embodiments of this application. In this embodiment, the support member 20 and the bracket 30 are insulated from each other, that is, there is no contact resistance R between the support member 20 and the bracket 30. c And the fundamental current amplitude I0, thereby improving the RSE problem.
[0102] The abutment 20 may include a first fixing part 21, a first connecting part 23, and a first conducting part 25 that are fixed to each other, and the abutment 20 may be an integral structure. The first connecting part 23 connects the first fixing part 21 and the first conducting part 25, and the first fixing part 21 and the first conducting part 25 are respectively connected to opposite ends of the first connecting part 23. Both the first fixing part 21 and the first conducting part 25 are bent relative to the first connecting part 23, and the first fixing part 21 and the first conducting part 25 may be located on the same side of the first connecting part 23 or on opposite sides of the first connecting part 23. Figure 21 In the embodiment shown, the first fixing part 21 and the first conducting part 25 are located on the same side of the first connecting part 23, and the cross-section of the abutment member 20 along one direction is approximately C-shaped.
[0103] The bracket 30 may include a second fixing part 31, a second connecting part 33, and a second conducting part 35 that are fixed to each other. The bracket 30 may be an integral structure. The second connecting part 33 connects the second fixing part 31 and the second conducting part 35, and the second fixing part 31 and the second conducting part 35 are respectively connected to opposite ends of the second connecting part 33. Both the second fixing part 31 and the second conducting part 35 are bent relative to the second connecting part 33. The second fixing part 31 and the second conducting part 35 may be located on the same side of the second connecting part 33 or on opposite sides of the second connecting part 33.
[0104] The first conductive portion 25 includes a first surface 252, and the second conductive portion 35 includes a second surface 352. An insulating layer 39g is disposed on the first surface 252 and / or the second surface 352, located between the first surface 252 and the second surface 352. The insulating layer 39g can be made of insulating varnish. The first surface 252 and / or the second surface 352 are curved surfaces. Compared to a cross-sectional connection, this embodiment uses a smoothly transitioned curved surface for connection. The curved surface is smoother, which helps protect the integrity of the insulating layer 39g, and provides stable insulation between the first conductive portion 25 and the second conductive portion 35.
[0105] When manufacturing the bracket 30 or the abutment 20, an insulating layer 39g is usually set first, and then the bracket 30 or the abutment 20 is made into a specific shape. The insulating layer 39g may crack, but since the first surface 252 and / or the second surface 352 are curved, the first surface 252 and the second surface 352 will not be directly connected, and a stable insulating connection can still be achieved between the first conductive part 25 and the second conductive part 35.
[0106] The structures of the first conductive section 25 and the second conductive section 35 can be adopted. Figures 4 to 10 The structure in the illustrated embodiment is sufficient to achieve a stable insulating connection between the first conductive part 25 and the second conductive part 35.
[0107] The embodiments of this application can improve the RSE problem by means of stable electrical connection, current shunting or stable insulation between the support member 20 and the bracket 30.
[0108] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
