Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to an antenna connection component and electronic device. Background Technology

[0002] In related technologies, electronic devices such as mobile phones and tablets have antennas mounted on their mid-frames, also known as mid-frame antennas. Mid-frame antennas typically utilize spring clips connected to the motherboard for electrical connection, enabling the antenna to function.

[0003] The spring contacts often occupy a large area on the motherboard, which reduces the area utilization of the motherboard. On the other hand, if the available area on the motherboard is small, the spring contacts cannot achieve a reliable connection, resulting in the mid-frame antenna not being able to be electrically connected to the motherboard. Summary of the Invention

[0004] Therefore, this utility model provides an antenna connection component and electronic device that can reduce the area occupied by the antenna connection component on the printed circuit board while ensuring the stability of the antenna connection. The technical solution is as follows:

[0005] A first aspect provides an antenna connection assembly, the antenna connection assembly including a first electrical connector and a second electrical connector;

[0006] The first electrical connector is used to be mounted on the printed circuit board of the electronic device and is electrically connected to the power supply circuit of the printed circuit board;

[0007] The second electrical connector includes a first connection structure, a spring arm, and a first contact structure;

[0008] The first connection structure is used to be installed on the inner side of the middle frame of the electronic device and electrically connected to the frame antenna inside the middle frame;

[0009] The first end of the spring arm is connected to the first connecting structure, and the second end of the spring arm extends obliquely toward the first electrical connector and is connected to the first contact structure, wherein the first contact structure abuts against the first electrical connector.

[0010] In this embodiment, the antenna connection assembly mounts a second electrical connector with a spring-loaded arm onto the inner side of the electronic device frame via a first connection structure. The spring-loaded arm allows the first contact structure to abut against the first electrical connector mounted on the printed circuit board of the electronic device, achieving a stable and reliable electrical connection between the printed circuit board and the frame antenna. Furthermore, because the second electrical connector has a spring-loaded abutment function, the first electrical connector does not need to employ a spring-loaded structure, thus reducing its footprint on the printed circuit board.

[0011] In some possible implementations, the first connection structure is used to be installed on the inside of one frame edge of the middle frame, and the first electrical connector includes a second connection structure and a second contact structure.

[0012] The second connection structure is adapted to be mounted on the front side of the printed circuit board and electrically connected to the power supply circuit of the printed circuit board;

[0013] The first end of the second contact structure is connected to the second connection structure, and the second end of the second contact structure extends in a third direction;

[0014] Wherein, the third direction is parallel to the second plane containing the length and width directions of the corresponding frame edge, and the first contact structure and the second contact structure abut against the side of the corresponding frame edge.

[0015] The second connection structure can be stably connected to the front of the printed circuit board. The second end of the second contact structure extends along the third direction, which helps to increase the contact area between the first contact structure and the second contact structure.

[0017] The side of the second contact structure away from the corresponding frame edge is attached to the end face of the printed circuit board, which can prevent the connection between the second connection structure and the printed circuit board from being displaced due to force, and prevent the second contact structure from deforming, resulting in poor contact between the second contact structure and the first contact structure.

[0020] Wherein, the first direction is the length direction of the corresponding frame edge, and the second direction is the width direction of the corresponding frame edge.

[0021] The spring arm extends along the length of the corresponding frame edge, allowing the second contact element to occupy a larger area on the frame edge for arrangement, which helps to improve the strength of the spring arm and reduce the yielding amount of the spring arm.

[0022] In some possible implementations, the first connection structure further includes a second extension connected to the first extension, both the first extension and the second extension being connected to the corresponding frame edge, and the second extension extending along the first direction.

[0023] The second extension can lengthen the lever arm of the first connecting structure, thereby improving the stability of the connection between the first connecting structure and the frame edge and preventing the connection between the first connecting structure and the frame edge from becoming loose.

[0024] In some possible implementations, the spring arm includes a first reinforcing section and a first biasing section connected together;

[0025] The first end of the first reinforcing segment is connected to the first extension, and the second end of the first reinforcing segment extends obliquely toward the first electrical connector along the first direction.

[0026] The first end of the first bias segment is connected to the second end of the first reinforcing segment, and the second end of the first bias segment bends toward the first electrical connector and extends toward the first electrical connector along the first direction;

[0027] The first contact structure is connected to the second end of the first bias segment.

[0028] The first reinforcing section and the first offset section are connected by a relative bend, which can improve the strength of the spring arm and help improve the stability of the antenna connection assembly.

[0029] In some possible implementations, the first connecting structure extends along a first direction and is connected to one edge of the middle frame;

[0030] The first end of the spring arm is connected to the first side of the first connecting structure, and the second end of the spring arm extends toward the second side of the first connecting structure and toward the first electrical connector, so that the first connecting structure is located on the side of the spring arm away from the first electrical connector.

[0031] Wherein, the first side and the second side are respectively the two opposite sides of the first connecting structure along the second direction, and the first direction is the length direction of the corresponding frame edge, and the second direction is the width direction of the corresponding frame edge.

[0032] The spring arm bends in the opposite direction to the first connecting structure, thus reducing the area occupied by the second electrical connector on the frame edge and saving space.

[0033] In some possible implementations, the spring arm includes a connected second reinforcing section and a second offset section;

[0034] The first end of the second reinforcing segment is connected to the first side of the first connecting structure, and the second end of the second reinforcing segment extends toward the second side of the first connecting structure;

[0036] The first contact structure is connected to the second end of the second bias segment.

[0037] The second reinforcing section and the second offset section are connected by a relative bend, which can improve the strength of the spring arm and help improve the stability of the antenna connection assembly.

[0045] The first electrical connector includes a second connection structure and a second contact structure;

[0047] The first end of the second contact structure is connected to the second connection structure, and the second end of the second contact structure extends into the clearance groove along the third direction. The side of the second contact structure facing the corresponding frame edge is flush with the top of the clearance groove. The first contact structure and the side of the second contact structure facing the corresponding frame edge are in contact with each other.

[0048] The second end of the second contact structure extends along the third direction into the clearance groove located on the end face of the printed circuit board, so that the side of the second contact structure facing the corresponding frame edge can be flush with the top of the clearance groove without protruding, thereby reducing the area occupied by the first electrical connector and avoiding space waste.

[0070] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0071] Firstly, reference Figure 1 As shown, this embodiment relates to an antenna connection assembly, which includes a first electrical connector 1 and a second electrical connector 2.

[0072] Among them, such as Figure 1 As shown, the first electrical connector 1 is used to be mounted on the printed circuit board 3 of the electronic device and is electrically connected to the power supply circuit of the printed circuit board 3. Combined with... Figure 15 and Figure 16 As shown, a solder plate 32 can be soldered to the front side of the printed circuit board 3. The first electrical connector 1 can be fixedly connected to the solder plate 32 by spot welding, thereby being fixedly installed on the front side of the printed circuit board 3 and electrically connected to the power supply circuit of the printed circuit board 3.

[0073] refer to Figure 3 or Figure 6 As shown, the second electrical connector 2 includes a first connecting structure 21, a spring arm 22, and a first contact structure 23. (Referring to...) Figure 2 and combined Figure 3 and Figure 6 As shown, the first connection structure 21 is used to be installed on the inner side of the middle frame 4 of the electronic device and electrically connected to the frame antenna inside the middle frame 4.

[0074] For example, the frame antenna is made of metal. To prevent interference with the frame antenna, the middle frame 4 also has a non-metallic support portion, such as plastic. In this embodiment of the invention, the frame antenna and the support portion can be integrally formed. For example, the frame antenna and the support portion can be formed into a single structure to form the middle frame 4 through a nano-injection molding process. Thus, the middle frame 4 has both metal and non-metal regions, where the metal region can serve as the frame antenna and the non-metal region can serve as the support portion. The first connecting structure 21 can be connected to the frame antenna by spot welding, or the first connecting structure 21 can be partially connected to the support portion by laser welding and partially connected to the frame antenna by spot welding.

[0075] like Figure 3 or Figure 6 As shown, the first end of the spring arm 22 is connected to the first connecting structure 21, and the second end of the spring arm 22 extends obliquely toward the first electrical connector 1 and is connected to the first contact structure 23. The first contact structure 23 abuts against the first electrical connector 1. Thus, a reliable electrical connection can be achieved between the frame antenna and the feed circuit of the printed circuit board 3 through the first electrical connector 1 and the second electrical connector 2.

[0076] Therefore, the antenna connection assembly of this embodiment, by mounting the second electrical connector 2 with a spring arm 22 on the inner side of the electronic device frame 4 through the first connection structure 21, and by using the spring arm 22 to make the first contact structure 23 abut against the first electrical connector 1 mounted on the printed circuit board 3 of the electronic device, can achieve a stable and reliable electrical connection between the printed circuit board 3 and the frame antenna. Furthermore, since the second electrical connector 2 has an elastic abutment function, the first electrical connector 1 does not need to use a spring-loaded or other elastic structure, thus reducing the area it occupies on the printed circuit board 3.

[0077] In some possible implementations, such as Figure 2 As shown, the first connecting structure 21 is used to install on the inner side of one frame edge 41 of the middle frame 4. (Reference) Figure 9 As shown, the first electrical connector 1 includes a second connection structure 11 and a second contact structure 12.

[0078] refer to Figure 12 As shown, the second connection structure 11 is adapted to be mounted on the front side of the printed circuit board 3 and electrically connected to the power supply circuit of the printed circuit board 3. For example Figure 16 As shown, the second connection structure 11 can be soldered to the front side of the printed circuit board 3 via the solder plate 32 and electrically connected to the power supply circuit of the printed circuit board 3.

[0079] Continue to refer to Figure 9 The first end of the second contact structure 12 is connected to the second connection structure 11, and the second end of the second contact structure 12 extends along the third direction.

[0080] Among them, for example Figure 10 and combined Figure 1 and Figure 2 As shown, the third direction is parallel to the second plane where the length and width directions of the corresponding frame edge 41 are located, and the first contact structure 23 and the second contact structure 12 abut against each other on the side facing the corresponding frame edge 41.

[0081] Thus, the first electrical connector 1 can maintain a stable connection with the printed circuit board 3 through the second connection structure 11. The second end of the second contact structure 12 extends in the third direction, which helps to increase the contact range between the first contact structure 23 and the second contact structure 12, thereby improving the stability of the antenna connection assembly connection.

[0082] In some possible implementations, refer to Figure 12As shown, the third direction intersects with the printed circuit board 3, and the second end of the second contact structure 12 extends toward the first end of the third direction. For example, the third direction can be perpendicular to the printed circuit board 3. Thus, the side of the second contact structure 12 away from the corresponding frame edge 41 can be attached to the end face of the printed circuit board 3. The corresponding frame edge 41 is the frame edge 41 connected to the first electrical connector 1.

[0083] In this way, when the second contact structure 12 is subjected to the compressive force of the first contact structure 23, the printed circuit board 3 can support the second contact structure 12. This prevents any impact on the stability of the connection between the second connection structure 11 and the printed circuit board 3. It also helps prevent deformation of the second contact structure 12, which could affect the stability of the contact between the second contact structure 12 and the first contact structure 23.

[0084] In some possible implementations, refer to Figure 12 As shown, the length of the second contact structure 12 is less than or equal to the thickness of the printed circuit board 3. This avoids wasting space by having the first end of the second contact structure 12 extend beyond the printed circuit board 3 in a third direction.

[0085] In some possible implementations, refer to Figure 9 and Figure 12 As shown, the second connecting structure 11 and the second contact structure 12 are integrally formed sheet-like structures. The second connecting structure 11 is bonded to the printed circuit board 3; for example, the second connecting structure 11 can be soldered to and bonded to the printed circuit board 3 via a solder pad 32. The second contact structure 12 is bent from the second connecting structure 11 and extends in a third direction.

[0086] This not only reduces the number of parts, improving the assembly and manufacturing efficiency of the antenna connection assembly, but also enhances the strength of the first electrical connector 1 and the stability of the antenna connection assembly. Furthermore, it reduces the possibility of damage to the first electrical connector 1 and extends its service life.

[0087] In addition, the second connection structure 11 is attached to the printed circuit board 3, which helps to improve the stability of the connection between the second connection structure 11 and the printed circuit board 3 and prevents the first electrical connector 1 from falling off.

[0088] In some possible implementations, refer to Figure 9 As shown, the second connecting structure 11 and the second contact structure 12 are integrally formed T-shaped sheets. The lateral extension of the T-shaped sheet becomes the second connecting structure 11, and the vertical extension of the T-shaped sheet becomes the second contact structure 12. Therefore, the lateral extension of the T-shaped sheet as the second connecting structure 11 helps to improve the stability of the connection between the second connecting structure 11 and the printed circuit board 3.

[0089] In some possible implementations, refer to Figure 9 As shown, the lateral extension has two process grooves 111 on the side near the vertical extension. The process grooves 111 extend through the lateral extension along its thickness direction, and the two process grooves 111 are located on opposite sides of the second contact structure 12. The presence of the two process grooves 111 facilitates the bending process of the vertical extension, making the manufacturing of the first electrical connector 1 simpler.

[0090] In some possible implementations, refer to Figure 3 and combined Figure 2 As shown, the first connecting structure 21 includes a first extension 213, which extends along a second direction and is connected to a frame edge 41 of the middle frame 4. For example, the first extension 213 and the metal area of ​​a frame edge 41 can be fixedly connected together by spot welding.

[0091] refer to Figure 3 and Figure 10 As shown, the first end of the spring arm 22 is connected to the first extension 213, and the second end of the spring arm 22 extends obliquely toward the first electrical connector 1 along the first direction.

[0092] Among them, combined Figure 1 and Figure 2 As shown, the first direction is the length direction of the corresponding frame edge 41, and the second direction is the width direction of the corresponding frame edge 41.

[0093] In this embodiment, since the first extension 213 extends along the second direction and the second end of the spring arm 22 extends obliquely towards the first electrical connector 1 along the first direction, the second contact 2 can occupy a larger area on the frame edge 41 for arrangement, which is beneficial to improving the strength of the spring arm 22 and thus improving the stability of the antenna connection assembly. At the same time, it is also beneficial to reduce the yielding amount of the spring arm 22 and improve the service life of the spring arm 22.

[0094] In some possible implementations, refer to Figure 3 As shown, the first connecting structure 21 also includes a second extension 214 connected to the first extension 213. Both the first extension 213 and the second extension 214 are connected to the corresponding frame edge 41, and the second extension 214 extends along the first direction. For example, both the first extension 213 and the second extension 214 can be fixedly connected to the metal area of ​​the corresponding frame edge 41 by spot welding.

[0095] Since the second extension 214 extends along the first direction, and both the first extension 213 and the second extension 214 are connected to the frame edge 41, the lever arm of the first connecting structure 21 along the first direction can be increased. This is beneficial to improving the stability of the connection between the first connecting structure 21 and the frame edge 41 when the spring arm 22 is squeezed by the first electrical connector 1, and helps to prevent the connection between the first connecting structure 21 and the frame edge 41 from becoming loose.

[0096] In some possible implementations, refer to Figure 3 As shown, the first end of the second extension 214 is connected to the first extension 213, and the second end of the second extension 214 and the second end of the spring arm 22 both extend toward the first end in the first direction.

[0097] Thus, since both the second end of the second extension 214 and the second end of the spring arm 22 extend towards the first end in the first direction, when the spring arm 22 is compressed by the first electrical connector 1, the second end of the second extension 214 can extend the lever arm of the first connecting structure 21 along the first direction by providing support. Therefore, compared to the second ends of the second extension 214 and the spring arm 22 extending in opposite directions, the fact that both the second ends of the second extension 214 and the spring arm 22 extend towards the same end in the first direction provides better stability.

[0098] In some possible implementations, refer to Figure 4 As shown, the projection of the second extension 214 onto the frame edge 41 does not overlap with the projection of the spring arm 22 onto the frame edge 41. This prevents the spring arm 22 from obstructing the second extension 214, thus facilitating the connection between the second extension 214 and the corresponding frame edge 41.

[0099] In some possible implementations, refer to Figures 3 to 5 As shown, the spring arm 22 includes a first reinforcing section 223 and a first offset section 224 connected together.

[0100] Among them, reference Figure 5 and Figure 10 As shown, the first end of the first reinforcing segment 223 is connected to the first extension 213, and the second end of the first reinforcing segment 223 extends obliquely toward the first electrical connector 1 along a first direction. The first end of the first biasing segment 224 is connected to the second end of the first reinforcing segment 223, and the second end of the first biasing segment 224 bends toward the first electrical connector 1 and extends toward the first electrical connector 1 along a first direction. The first contact structure 23 is connected to the second end of the first biasing segment 224.

[0101] In this way, the bending arrangement of the first reinforcing section 223 and the second offset section 224 can improve the strength of the spring arm 22, which is beneficial to improving the stability of the antenna connection assembly.

[0102] In some possible implementations, refer to Figure 3 and combined Figure 5 As shown, the first connecting structure 21 and the spring arm 22 are integrally formed sheet-like structures. The spring arm 22 bends from the first connecting structure 21 toward the first electrical connector 1 and extends toward the first electrical connector 1 along a first direction. For example, the first extension 213, the second extension 214, the first reinforcing section 223, and the second offset section 224 are all integrally formed.

[0103] In this way, the first connecting structure 21 and the spring arm 22 are integrally formed as a sheet, which not only reduces the number of parts and improves the assembly and manufacturing efficiency of the antenna connection assembly, but also enhances the strength of the second electrical connector 2 and the stability of the antenna connection assembly. Furthermore, it helps to reduce the possibility of damage to the second electrical connector 2 and extends its service life.

[0104] In some possible implementations, refer to Figure 6 and combined Figure 2 As shown, the first connecting structure 21 extends along a first direction and is connected to one edge 41 of the middle frame 4. For example, the first connecting structure 21 can be fixedly connected to the frame antenna by spot welding.

[0105] refer to Figure 6 and Figure 11 As shown, the first end of the spring arm 22 is connected to the first side of the first connecting structure 21, and the second end of the spring arm 22 extends toward the second side of the first connecting structure 21 and toward the first electrical connector 1, thereby, as Figure 11 As shown, the first connecting structure 21 is located on the side of the spring arm 22 away from the first electrical connector 1.

[0106] Among them, combined Figure 1 and Figure 2 As shown, the first side and the second side are opposite sides of the first connecting structure 21 along the second direction, and the first direction is the length direction of the corresponding frame edge 41, and the second direction is the width direction of the corresponding frame edge 41.

[0107] In this embodiment, since the first end of the spring arm 22 is connected to the first side of the first connecting structure 21, and the second end of the spring arm 22 extends toward the second side of the first connecting structure 21, the spring arm 22 bends in the opposite direction relative to the first connecting structure 21. Therefore, the area occupied by the second electrical connector 2 on the frame edge 41 can be reduced, saving space.

[0108] In some possible implementations, refer to Figure 6 and Figure 8As shown, the first end of the spring arm 22 is connected to the middle section of the first side of the first connecting structure 21. The first connecting structure 21 has two connecting parts 211, which are located on opposite sides of the spring arm 22 along the first direction. The first connecting structure 21 is adapted to be connected to the corresponding frame edge 41 through the two connecting parts 211.

[0109] Thus, the first end of the spring arm 22 is connected to the middle section of the first side of the first connecting structure 21, and the first connecting structure 21 is connected to the frame edge 41 through two connecting portions 211 located on opposite sides of the spring arm 22 along the first direction. Therefore, when the spring arm 22 is subjected to the compressive force of the first electrical connector 1, the supporting force of the first connecting structure 21 on both sides of the spring arm 22 is relatively balanced, which helps to improve the stability of the spring arm 22 under force, thereby helping to improve the stability of the antenna connection assembly connection.

[0110] In addition, since the two connecting parts 211 are located on both sides of the spring arm 22, the spring arm 22 avoids obstructing the connecting parts 211, which facilitates the connection between the connecting parts 211 and the corresponding frame edge 41.

[0111] In some possible implementations, refer to Figures 6 to 8 As shown, the spring arm 22 includes a second reinforcing section 221 and a second offset section 222 connected together.

[0112] Among them, reference Figure 7 and Figure 11 As shown, the first end of the second reinforcing segment 221 is connected to the first side of the first connecting structure 21, and the second end of the second reinforcing segment 221 extends toward the second side of the first connecting structure 21. The first end of the second biasing segment 222 is connected to the second end of the second reinforcing segment 221, and the second end of the second biasing segment 222 bends toward the first electrical connector 1 and extends toward the second side of the first connecting structure 21. The first contact structure 23 is connected to the second end of the second biasing segment 222.

[0113] In this way, the bending arrangement of the second reinforcing section 221 and the second offset section 222 can improve the strength of the spring arm 22, which is beneficial to improving the stability of the antenna connection assembly.

[0114] In some possible implementations, refer to Figure 6 As shown, the first connecting structure 21 and the spring arm 22 are integrally formed sheet-like structures. The spring arm 22 bends from the first side of the first connecting structure 21 and extends towards the second side of the first connecting structure 21 and facing the first electrical connector 1. For example, the first connecting structure 21, the second reinforcing section 221, and the second offset section 222 can all be integrally formed.

[0115] In this way, the first connecting structure 21 and the spring arm 22 are integrally formed as a sheet, which not only reduces the number of parts and improves the assembly and manufacturing efficiency of the antenna connection assembly, but also enhances the strength of the second electrical connector 2 and the stability of the antenna connection assembly. Furthermore, it helps to reduce the possibility of damage to the second electrical connector 2 and extends its service life.

[0116] In some possible implementations, the second side of the first connecting structure 21 has a protrusion 212 that fits against the frame edge 41.

[0117] Thus, the protrusion 212 is located on the second side of the first connecting structure 21, while the first end of the spring arm 22 is connected to the first side of the first connecting structure 21, and the second end of the spring arm 22 extends towards the second side of the first connecting structure 21 and towards the first electrical connector 1. Therefore, the presence of the protrusion 212 can lengthen the lever arm between the first and second sides of the first connecting structure 21, thereby improving the stability of the connection between the first connecting structure 21 and the frame edge 41 when the spring arm 22 is squeezed by the first electrical connector 1, and helping to prevent the connection between the first connecting structure 21 and the frame edge 41 from loosening. At the same time, the protrusion 212 occupies a small area, saving space.

[0118] In some possible implementations, refer to Figure 8 As shown, both the protrusion 212 and the spring arm 22 are symmetrically arranged with the first plane as the central plane, wherein the first plane is perpendicular to the first direction. In this way, the forces on both sides of the spring arm 22 are relatively balanced, which is conducive to further improving the stability of the antenna connection assembly. Moreover, the relatively balanced forces on both sides of the protrusion 212 are conducive to further reducing the possibility of loosening of the connection between the first connecting structure 21 and the frame edge 41.

[0119] In some possible implementations, refer to Figure 3 and Figure 6 As shown, the spring arm 22 is plate-shaped, and its second end has a linear or circular protrusion, which serves as the first contact structure 23. Using the linear or circular protrusion on the spring arm 22 as the first contact structure 23 reduces the number of components, improving the assembly and manufacturing efficiency of the antenna connection assembly. It also enhances the strength of the second electrical connector 2, improving the stability of the antenna connection assembly. Furthermore, it reduces the possibility of damage to the second electrical connector 2, extending its service life. Simultaneously, the linear or circular protrusion ensures stable contact with the first electrical connector 1.

[0120] Secondly, refer to Figures 13 to 18As shown, this embodiment provides an electronic device, which includes a printed circuit board 3, a middle frame 4, and the antenna connection assembly of this utility model.

[0121] like Figure 13 As shown, the middle frame 4 includes multiple frame edges 41, which are connected end to end to form the middle frame 4. The printed circuit board 3 is located inside the middle frame 4.

[0122] like Figure 14 As shown, the first electrical connector 1 is mounted on the printed circuit board 3 of the electronic device and is electrically connected to the power supply circuit of the printed circuit board 3. The first connection structure 21 is mounted on the inner side of a frame edge 41 and is electrically connected to the frame antenna inside the middle frame 4.

[0123] The electronic device in this embodiment uses the antenna connection component of this application, and can have all the beneficial technical effects of the embodiments of this application.

[0124] In some possible implementations, refer to Figure 15 As shown, the end face of the printed circuit board 3 has a clearance groove 31, which penetrates at least the front surface of the printed circuit board 3 along a third direction. This third direction is parallel to the second plane containing the length and width directions of the corresponding frame edge 41. For example, the third direction can also be perpendicular to the printed circuit board 3.

[0125] refer to Figure 16 As shown, the first electrical connector 1 includes a second connection structure 11 and a second contact structure 12. The second connection structure 11 is adapted to be mounted on the front side of the printed circuit board 3 and electrically connected to the power supply circuit of the printed circuit board 3.

[0126] refer to Figure 17 or Figure 18 As shown, the first end of the second contact structure 12 is connected to the second connection structure 11, and the second end of the second contact structure 12 extends into the relief groove 31 in a third direction. The side of the second contact structure 12 facing the corresponding frame edge 41 is flush with the top of the relief groove 31. The first contact structure 23 and the side of the second contact structure 12 facing the corresponding frame edge 41 are in contact.

[0127] In this embodiment, since the second end of the second contact structure 12 extends in a third direction into the clearance groove 31 located on the end face of the printed circuit board 3, the side of the second contact structure 12 facing the corresponding frame edge 41 can be flush with the top of the clearance groove 31 without protruding. This helps to reduce the area occupied by the first electrical connector 1 and avoid space waste.

[0128] In some possible implementations, the electronic device can be any of a variety of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or a smartphone. For example, iPhone™-based phones, Android™-based phones, portable gaming devices such as Nintendo DS™, PlayStation Portable™, Gameboy Advance™, iPhone™, laptops, PDAs, portable internet devices, music players and data storage devices, other handheld devices, and such as headsets, etc. The electronic device can also be other wearable devices that require charging, such as head-mounted devices (HMDs) such as electronic bracelets, electronic necklaces, electronic devices, or smartwatches.

[0129] Electronic devices can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smartphones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transport instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbooks, personal digital assistants (PDAs), portable multimedia players (PMPs), MPEG-1 or MPEG-G-2 audio layer 3MP3 players from the Moving Image Experts Group, portable medical devices, and digital cameras and combinations thereof.

[0130] In some cases, electronic devices can perform multiple functions (e.g., playing music, displaying video, storing pictures, and receiving and sending telephone calls). If desired, electronic devices can be such as cellular phones, media players, other handheld devices, wristwatches, pendant devices, handset devices, or other compact portable devices.
