Description

Sockets, plugs, electrical connectors, electronic components and equipment

[0001] This application claims priority to Chinese patent application filed on December 20, 2024, with application number 202411914439.5, entitled "Socket, Plug Component, Electrical Connector, Electronic Component and Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electrical connector structure technology, and in particular to a socket, plug component, electrical connector, electronic component and device. Background Technology

[0003] In related technologies, two circuit boards can be electrically connected via a board-to-board (BTB) connector. One circuit board has a socket (female), and the other has a plug (male). During the socket and plug engagement, only the socket is visible, and the plug is not; the engagement is achieved through blind snapping. To minimize the area occupied by the connector on the circuit board, the terminal dimensions and spacing within the connector need to be reduced. However, during blind snapping, significant engagement deviations are prone to occur between the socket and plug. Summary of the Invention

[0004] This application provides a socket, plug component, electrical connector, electronic component, and device to solve the problem of large engagement deviations that can easily occur during the blind snapping process of sockets and plugs.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a socket for mating with a plug. The plug is used to connect to an electronic component. The socket includes a first base and a first terminal group. The socket has a positioning portion. The positioning portion is used to be inserted into a positioning hole of the electronic component.

[0007] The socket provided in this application embodiment has a positioning part, and the electronic component connected to the plug has a positioning hole. Before the socket and plug are fastened together, the positioning part of the socket is inserted into the positioning hole of the electronic component, so as to realize the rapid pre-positioning of the socket and plug, so as to minimize the deviation before fastening, thereby enabling the socket and plug to be accurately fastened and matched, and reducing the damage caused by forcibly fastening the socket and plug.

[0008] In one alternative implementation, the first base may be made of an insulating material. The first terminal group has a plurality of first terminals, which may be made of conductive metal. The plurality of first terminals are fixed to the first base and insulated from each other. The plurality of first terminals may serve as signal terminals.

[0009] In one alternative implementation, the first base includes a pair of first sidewalls and a pair of first endwalls. The first sidewalls extend along the length of the first base, and the pair of first sidewalls are spaced apart along the width of the first base. The pair of first endwalls are distributed at opposite ends along the length of the first base. The two first sidewalls and the two first endwalls can be arranged in a generally rectangular shape. The first base also includes a central island portion located between the two first endwalls and also between the two first sidewalls. An annular groove is formed between the two first sidewalls, the two first endwalls, and the central island portion, and the annular groove has an opening.

[0010] In one alternative implementation, the first base further includes a first bottom plate, and the first end wall, the first side wall, and the central island portion are connected to the same side of the first bottom plate.

[0011] In one alternative implementation, the first base and the first terminal group in the socket can be an integral structure. During manufacturing, multiple first terminals are first stamped, and then an insert injection molding process is used to tightly bond the first base material to the first terminals to form an integral structure.

[0012] In one alternative implementation, the first base and the first terminal group can also be an assembly structure, wherein the first base and the first terminal group are first manufactured, and then the first terminal group is inserted into the first base.

[0013] In one alternative implementation, the top surface of the positioning part is higher than the top surface of the first base in the height direction. This facilitates the insertion of the positioning part of the socket into the positioning hole of the electronic component, enabling rapid pre-positioning of the socket and plug and minimizing the deviation before engagement.

[0014] In one alternative implementation, the socket has a pair of first reinforcing parts distributed at opposite ends along the length of the first base. The first reinforcing parts enhance the structural strength of the socket's end positions, reducing damage to the socket ends during the socket and plug insertion process. During the socket and plug insertion process, the first reinforcing parts provide a guiding function, ensuring smooth alignment and insertion of the socket and plug.

[0015] In one alternative implementation, the first reinforcing part includes a first end wall and a first fitting, the first fitting covering at least a portion of the surface of the first end wall. The first fitting can improve the structural strength at the first end wall location and reduce the possibility of contact wear and crush damage to the first end wall.

[0016] In one alternative implementation, the first fitting can be made of metal (such as copper) and can be manufactured using a drawing process, resulting in good structural strength.

[0017] In one alternative implementation, the first base can be injection molded using a first fitting as an insert, so that the material of the first base and the first fitting are tightly bonded together to form an integral structure.

[0018] In one alternative implementation, the first fitting may be assembled onto the first end wall by insert or other means. There may be a gap between the first end wall and the first fitting.

[0019] In one alternative implementation, the first reinforcing part can be a first end wall, and no first fitting is provided outside the first end wall. The first end wall is made of a high-strength material (such as ceramic).

[0020] In one alternative implementation, the bottom dimension of the first reinforcing part is larger than the top dimension of the first reinforcing part along the length of the first base. When the slot of the first base faces upward, the first reinforcing part is configured as a shape that is narrower at the top and wider at the bottom, such as a trapezoid or a dam shape. This can effectively improve the lateral strength of the first reinforcing part and reduce the possibility of damage to the first reinforcing part when the socket and plug are forcibly fastened due to large fastening deviations.

[0021] In one alternative implementation, the first reinforcing part includes a first end wall and a first fitting, with the first fitting covering the first end wall. The first end wall is configured to be narrower at the top and wider at the bottom, and the first fitting is also configured to be narrower at the top and wider at the bottom to cover the main body segment. This improves the thrust resistance of the first end wall and reduces the risk of damage to the first fitting and the first end wall when the socket and plug are forcibly fastened.

[0022] In one alternative implementation, the first reinforcing part is a first end wall, which is configured to be narrower at the top and wider at the bottom, thereby improving the thrust resistance of the first end wall and reducing damage to the first end wall when the socket and plug are forcibly fastened.

[0023] In one alternative implementation, the first reinforcing part is cut with a vertical plane in the width direction of the first base to form a cross-section. The outer surface of the first reinforcing part can be presented in a variety of predetermined shapes, such as an inclined line extending from the bottom towards the central island, an inclined line extending from the bottom away from the central island, or an outward convex arc line away from the central island.

[0024] In one alternative implementation, on the vertical plane along the height direction of the first base, the outer side projection of the first reinforcing part is at least partially convex arc-shaped. During the insertion process of the first base and the second base, the first end wall of the first base and the second end wall of the second base push against each other, causing extrusion deformation inside the first end wall. The convex arc-shaped first end wall can better disperse the internal stress, improve the structural strength of the first end wall, and reduce the possibility of the first end wall being crushed and damaged.

[0025] In one alternative implementation, the first fitting covers the outer side of the first end wall, and the first outer wall of the first fitting is convex arc-shaped.

[0026] In one alternative implementation, the first reinforcing part is a first end wall, and the outer surface of the first end wall is the outer surface of the first reinforcing part. The outer surface of the first end wall is convex arc-shaped.

[0027] In one alternative implementation, the first end wall includes a main body segment and a pair of auxiliary segments, the main body segment being located at the end along the length of the first base; the pair of auxiliary segments are respectively connected to both ends of the main body segment; the first fitting includes a main body portion and a pair of auxiliary portions, the pair of auxiliary portions being respectively connected to both ends of the main body portion, the main body portion covering at least a portion of the surface of the main body segment, and the auxiliary portions covering at least a portion of the surface of the auxiliary segments. By covering the main body segment with the main body portion, the structural strength of the main body segment is increased; by covering the auxiliary segments with the auxiliary portions, the structural strength of the auxiliary segments is increased. The first fitting and the first end wall are less likely to be damaged when the socket and plug are forcibly fastened.

[0028] In one alternative implementation, the main body segment can be arc-shaped, straight-lined, semi-circular, etc.

[0029] In one alternative implementation, the auxiliary segment can be linear or extend along the length of the first base or in other directions. The auxiliary segment of the first end wall can be connected to the first side wall to improve structural strength.

[0030] In one alternative implementation, the main body can be configured as a shape that is narrower at the top and wider at the bottom (such as a trapezoid or dam shape) to cover the main body section, thereby improving the thrust resistance of the main body section.

[0031] In one alternative implementation, the first outer wall of the first fitting is a smooth surface, and the first outer wall covers the outer surface of the first end wall, which can better disperse internal stress and improve structural strength.

[0032] In one alternative implementation, the bottom thickness of the appendage is greater than the top thickness. The appendage is designed with a shape that is narrower at the top and wider at the bottom (such as a trapezoid or dam shape) to enclose the appendage segment, which can improve the thrust resistance of the appendage segment.

[0033] In one alternative implementation, the bottom thickness of the appendix is ​​equal to the top thickness of the appendix.

[0034] In one alternative implementation, the outer wall of the main body is a continuous wall surface. This can improve the structural strength of the main body and the main body segment.

[0035] In one alternative implementation, the outer wall of the main body is a discontinuous wall surface. That is, the outer wall of the main body has holes, and the material of the main body can fill the holes, so that the materials of the main body and the main body segment are tightly bonded when the insert is injection molded into an integral structure.

[0036] In one alternative implementation, the outer wall of the appendage can be continuous or discontinuous. The inner wall of the appendage can also be continuous or discontinuous. When the appendage and the appendage segment are integrally molded as an insert, the materials of the appendage and the appendage segment are tightly bonded, resulting in a good bonding effect.

[0037] In one alternative implementation, the inner walls of the main body and the auxiliary body are connected. This improves the structural strength of both the main body and the auxiliary body. In another alternative implementation, the inner walls of the main body and the auxiliary body are spaced apart. That is, a hole is formed between the inner walls of the main body and the auxiliary body, and the first end wall material can fill the hole. During the injection molding of the insert to create an integral structure of the first fitting and the first end wall, the first fitting and the first end wall material are tightly bonded together.

[0038] In one alternative implementation, the first fitting has a first outer wall. The first outer wall of the first fitting can be presented in a variety of predetermined shapes by cutting the first fitting with a vertical plane in the width direction of the first base, such as an inclined line extending from the bottom towards the central island, an inclined line extending from the bottom away from the central island, or an outwardly convex arc line away from the central island.

[0039] In one alternative implementation, the first base includes a pair of first sidewalls extending along the length of the first base and spaced apart along the width of the first base. The first base also includes a pair of outer sidewalls spaced apart along the width of the first base, with the pair of first sidewalls located between the pair of outer sidewalls. The pair of first endwalls and the pair of outer sidewalls are combined to form a ring structure that surrounds the first sidewalls. A first fitting covers the first endwalls and also covers the outer sidewalls. This enhances the structural strength of the first base.

[0040] In one alternative implementation, the positioning portion is a protrusion formed on at least a portion of the top of at least one first fitting. Fabricating the protrusion and the first fitting as a single unit, such as a metal part manufactured using a drawing process, facilitates forming and provides good structural strength.

[0041] In one alternative implementation, two first fittings each have a protrusion, which are spaced apart along the length of the first base. The electronic component has two corresponding positioning holes. During the socket and plug engagement process, the two protrusions are inserted one-to-one into the two positioning holes. This enables quick and accurate engagement of the socket and plug, preventing damage to the socket and plug caused by tilted engagement.

[0042] In one alternative implementation, one of the first fittings has a protrusion, and the electronic component has a corresponding positioning hole. During the engagement of the socket and plug, the protrusion is inserted into the positioning hole to achieve pre-positioning of the socket and plug.

[0043] In one alternative implementation, the protrusion covers the filling material portion. The filling material portion is connected to the top of the first end wall.

[0044] In one optional implementation, the first fitting includes a first top wall, a first outer wall, and a first inner wall. The first top wall connects the first outer wall and the first inner wall. The first outer wall covers the outer surface of the first end wall and the outer surface of the filling material portion. The first inner wall covers the inner surface of the first end wall and the inner surface of the filling material portion. The first top wall at least covers the top surface of the filling material portion. The first fitting adopts a full-coverage method, covering the outer and inner surfaces of the first end wall, as well as the outer, top, and inner surfaces of the filling material portion. This can improve the structural strength of the first end wall and reduce contact wear between the first and second end walls.

[0045] In one alternative implementation, the first fitting includes a first top wall and a first outer wall, which are connected. The first outer wall covers the outer surface of the first end wall and the outer surface of the filling material portion, while the first top wall covers at least the top surface of the filling material portion. The first fitting employs a partial covering method, without a first inner wall, exposing the inner surface of the first end wall. This improves the structural strength of the first end wall and reduces damage to the first fitting and the first end wall when the socket and plug are forcibly fastened.

[0046] In one alternative implementation, the first fitting includes a first top wall and a first inner wall, which are connected. The first inner wall covers the inner surface of the first end wall and the inner surface of the filling material portion, and the first top wall covers at least the top surface of the filling material portion. The first fitting does not have a first outer wall; the outer surface of the first end wall is exposed. This improves the structural strength of the first end wall, reduces damage to the first fitting and the first end wall when the socket and plug are forcibly fastened, and reduces contact wear between the first end wall and the second end wall.

[0047] In one alternative implementation, the protrusion may not have a filling material section inside. The protrusion is part of the first fitting.

[0048] In one alternative implementation, the inner surface of the protrusion has a first guide surface; the first guide surface is used to mate with the second end wall of the plug. The first guide surface has a relatively long guiding distance, and during the insertion and connection of the socket and the plug, the first guide surface plays a good guiding role on the second end wall, enabling the socket and the plug to align quickly and smoothly, thereby achieving accurate engagement of the connector.

[0049] In one alternative implementation, the first guide surface can be set as an inclined surface or an arc surface.

[0050] In one alternative implementation, the upper part of the first inner wall of the first fitting can be an inclined first guide surface, which guides the second end wall, allowing the socket and plug to align quickly and accurately.

[0051] In one alternative implementation, the lower part of the first inner wall of the first fitting can be arranged vertically, that is, parallel to the height direction of the first base, so that the second end wall and the first end wall can push against each other, and the socket and plug are stably connected.

[0052] In one alternative implementation, the positioning part is a protrusion formed on a portion of the top of the first fitting. The electronic component has a positioning hole. The positioning hole and the positioning part are approximately dimensionally similar in both the length and width directions of the first base. During insertion into the positioning hole, the positioning part contacts the inner wall of the positioning hole, achieving positioning in the length direction of the first base. The positioning part also contacts the inner wall of the positioning hole, achieving positioning in the width direction of the first base. Positioning guidance in both directions is possible.

[0053] In one alternative implementation, the positioning part is a protrusion formed on a portion of the top of the first fitting. The electronic component has a positioning hole. The dimensions of the positioning hole and the positioning part are similar along the length of the first base. In the width direction of the first base, the size of the positioning hole is significantly larger than the size of the positioning part. During insertion of the positioning part into the positioning hole, the positioning part can contact the inner wall of the positioning hole, achieving positioning along the length of the first base. Positioning guidance in a single direction is possible.

[0054] In one alternative implementation, the positioning part is a boss located on the first base. For example, the positioning part can be located on the first end wall of the first base; the positioning part can be located on the central island portion of the first base; or the positioning part can be located on the first side wall of the first base. Positioning holes are provided at corresponding positions on the electronic component (second electronic component). By engaging the boss on the first base with the positioning holes, the pre-positioning of the socket and plug can be achieved.

[0055] In one alternative implementation, the positioning part can be assembled into the first base, or the positioning part can be integrally injection molded into the first base.

[0056] In one alternative implementation, the positioning part can be formed at the top of the island part. For example, a boss is provided at each end of the island part along the length of the first base, and positioning holes are provided at the corresponding positions of the second base of the plug and the electronic component.

[0057] In one alternative implementation, the boss is a columnar body extending along the height direction of the first base. Using a columnar boss allows for better mating with positioning holes on electronic components, achieving pre-positioning of the connector.

[0058] In one alternative implementation, the boss is connected to the first base and passes through the first fitting, making it easy to manufacture and assemble. During the engagement of the socket and plug, the boss is inserted into the positioning hole to achieve pre-positioning of the socket and plug.

[0059] In one alternative implementation, the first base has two columnar protrusions, which are correspondingly inserted into the first fitting. The two protrusions are spaced apart along the length of the first base, and the electronic component has two corresponding positioning holes. This enables the socket and plug to quickly and accurately engage and mate.

[0060] In one alternative implementation, the edge of the insertion end of the positioning part, which is inserted into the positioning hole, is chamfered. The chamfer of the positioning part serves as a guide, allowing the plug to smoothly enter the socket. Furthermore, the first end wall and the second end wall work together to provide segmented guidance, enabling the plug and socket to quickly engage.

[0061] In one alternative implementation, the wall of the positioning hole is chamfered, and the inner diameter of the positioning hole gradually decreases in the direction in which the positioning part is inserted into the positioning hole. During the insertion of the positioning part into the positioning hole, the wall of the positioning hole guides the positioning part, allowing the plug to smoothly enter the socket. Then, through the cooperation of the first end wall and the second end wall, segmented guidance is achieved, enabling the plug and socket to quickly engage.

[0062] In one alternative implementation, the first reinforcing part is a first end wall, meaning that no first fitting is provided outside the first end wall. The positioning part can be a boss located on at least part of the top of the first end wall. The inner side of the boss has a second guide surface; the second guide surface is used to mate with the second end wall of the plug. The second guide surface plays a good guiding role for the second end wall, enabling the socket and plug to align quickly and smoothly, thereby achieving accurate engagement of the connector.

[0063] In one alternative implementation, the second guide surface can be set as an inclined surface or an arc surface.

[0064] In one alternative implementation, each of the two first end walls has a boss, which enables the misalignment between the socket and plug to be less than or equal to 0.20 mm before they are engaged, thus achieving fast and accurate engagement of the socket and plug.

[0065] In one alternative implementation, the first terminal group in the socket includes multiple rows of first terminals, each row including multiple first inner terminals and multiple first outer terminals. The contact portions of the multiple first inner terminals are flush, and the contact portions of the multiple first outer terminals are also flush. The contact portions of the first inner terminals and the first outer terminals are spaced apart along the width direction of the first base. In the same row of first terminals, the first inner terminals and the first outer terminals are arranged alternately along the length direction of the first base. Viewed directly from the slot of the first base, the contact portions of the first inner terminals and the first outer terminals in the same row are arranged in a staggered, concave-convex manner. This prevents the first and second terminals from misaligning after the socket and plug are engaged, thus preventing circuit malfunction or short circuit risks. The socket and plug in the miniature connector can be quickly pre-positioned and accurately engaged, reducing damage caused by forcibly engaging the socket and plug when there is a large engagement deviation.

[0066] In one alternative implementation, the contact portion of the first inner terminal and the contact portion of the first outer terminal may have a generally U-shaped slot.

[0067] In one alternative implementation, in the socket, along the width direction of the first base, in two adjacent rows of first terminals, the first inner terminal in one row and the first outer terminal in the other row are arranged in a one-to-one correspondence.

[0068] In one alternative implementation, in the socket, along the width direction of the first base, the tail portion of the first inner terminal and the contact portion are arranged opposite to each other, and the tail portion of the first outer terminal and the contact portion are also arranged opposite to each other. The tail portion of the first inner terminal is located inside the first base along the width direction of the first base, and may be located in the central island portion. The tail portion of the first outer terminal is located outside the first base along the width direction of the first base, and may be located outside the first sidewall. The tail portions of the first inner terminal and the first outer terminal face opposite directions along the width direction of the first base. The first terminals in the same row can be reliably soldered onto the first electronic component, and adjacent first terminals are less likely to bridging during soldering.

[0069] In one alternative implementation, the first inner terminals and the first outer terminals in the same row of first terminals are arranged alternately, with their tails located correspondingly on the inner and outer sides of the first base. The spacing between adjacent first inner terminals and first outer terminals can be reduced by half, thereby reducing the length or area of ​​the socket. This achieves an ultra-miniature connector.

[0070] In one alternative implementation, the number of first terminal rows in the first terminal group and the number of second terminal rows in the second terminal group are equal, thus making them compatible.

[0071] Secondly, embodiments of this application provide a plug component, including a second electronic component and a plug, the plug being connected to the second electronic component; the plug includes a second base and a second terminal group, the second terminal group being disposed on the second base; the plug is used for insertion and mating with a socket, the socket having a positioning part; the second electronic component has a positioning hole, the positioning hole being used for insertion and mating with the positioning part.

[0072] The plug component provided in this application embodiment has a socket with a positioning part and a second electronic component connected to the plug with a positioning hole. Before the socket and plug are fastened together, the positioning part of the socket is inserted into the positioning hole of the electronic component (second electronic component) to achieve rapid pre-positioning of the socket and plug, so that the deviation before fastening is small, thereby enabling the socket and plug to be accurately fastened and matched, reducing the damage caused by forcibly fastening the socket and plug.

[0073] In one alternative implementation, the second electronic component may include a flexible circuit board and a reinforcing plate stacked on top of each other. The reinforcing plate can improve structural strength and can be a steel sheet, etc. Alternatively, the second electronic component may be a rigid circuit board. Alternatively, the second electronic component may be an electronic module. The second electronic component in the above embodiments can be equipped with a socket. The electronic module may be a camera module, a speaker module, etc.

[0074] In one alternative implementation, the positioning hole of the electronic component (second electronic component) can be a through hole that penetrates the electronic component, or a blind hole that does not penetrate the electronic component.

[0075] In one alternative implementation, the second electronic component includes a flexible circuit board and a reinforcing plate stacked on top of each other. A plug is connected to the flexible circuit board, and the reinforcing plate is located on the side of the flexible circuit board opposite to the plug. Openings can be provided at corresponding positions on the flexible circuit board and the reinforcing plate, and the two openings communicate to form positioning holes.

[0076] In one alternative implementation, the second base in the plug may be made of an insulating material (such as plastic). The second terminal group has multiple second terminals, which may be made of a conductive metal (such as copper). The multiple second terminals are fixed to the second base and insulated from each other. The multiple second terminals may serve as signal terminals.

[0077] In one alternative implementation, the second base in the plug includes a pair of second sidewalls and a pair of second endwalls. The second sidewalls extend along the length of the second base, and the pairs of second sidewalls are spaced apart along the width of the second base. The pairs of second endwalls are distributed at opposite ends along the length of the second base. The two second sidewalls and the two second endwalls can be arranged in a generally rectangular shape. A groove is formed between the two second sidewalls and the two second endwalls, and the groove has an opening.

[0078] In one alternative implementation, the second end wall and the second side wall can be connected to the same side of the second base plate.

[0079] In one alternative implementation, the second end wall and the second side wall are directly connected.

[0080] In one alternative implementation, the second base and the second terminal group in the plug can be an integral structure. During manufacturing, multiple second terminals are first stamped, and then an insert injection molding process is used to tightly bond the second base material to the second terminals to form an integral structure.

[0081] In one alternative implementation, the second base and the second terminal group can also be an assembly structure, in which the second base and the second terminal group are first manufactured, and then the second terminal group is inserted into the second base.

[0082] In one alternative implementation, during the insertion and connection of the socket and plug, the second sidewall and second endwall of the second base can be inserted into the annular groove of the first base, the second sidewall and second endwall surround the central island portion of the first base, and the central island portion of the first base can be inserted into the groove of the second base. When the socket and plug are fully inserted / engaged, the first sidewall and second sidewall push against each other in a corresponding manner, and the first endwall and second endwall push against each other in a corresponding manner.

[0083] In one alternative implementation, the plug has a pair of second reinforcing portions distributed at opposite ends along the length of the second base. The second reinforcing portions enhance the structural strength of the plug tip, reducing damage to the plug tip during the plug-socket connection process. During the plug-socket connection, the second reinforcing portions provide guidance, ensuring smooth alignment and insertion of the plug and socket.

[0084] In one alternative implementation, the second reinforcement includes a second end wall and a second fitting, the second fitting covering at least a portion of the surface of the second end wall. The second fitting can improve the structural strength at the second end wall location and reduce the possibility of contact wear and crush damage to the second end wall.

[0085] In one alternative implementation, the second fitting can be made of metal (such as copper) and can be manufactured using a drawing process, resulting in good structural strength.

[0086] In one alternative implementation, the second base can be injection molded using a second fitting as an insert, so that the material of the second base, the second fitting, and the second terminal group are tightly bonded together.

[0087] In one alternative implementation, the second fitting may be assembled onto the second base by insert or other means.

[0088] In one alternative implementation, the second reinforcing part is a second end wall, meaning that no second fitting is provided outside the second end wall. The second end wall is made of a high-strength material (such as ceramic).

[0089] In one alternative implementation, the bottom dimension of the second reinforcing part is larger than the top dimension of the second reinforcing part along the length of the second base. When the slot of the second base faces upward, the second reinforcing part is configured as a shape that is narrower at the top and wider at the bottom, such as a trapezoid or a dam shape. This can effectively improve the lateral strength of the second reinforcing part and reduce the possibility of damage to the second reinforcing part when the socket and plug are forcibly fastened due to large fastening deviations.

[0090] In one alternative implementation, the second reinforcing part includes a second end wall and a second fitting, with the second fitting covering the second end wall. When the slot of the second base faces upward, the second fitting is configured to be narrower at the top and wider at the bottom, covering the surface of the second end wall. This improves the thrust resistance of the second fitting and reduces damage to the second fitting and the second end wall when the socket and plug are forcibly fastened.

[0091] In one alternative implementation, the second reinforcing part is a second end wall. When the slot of the second base faces upward, the second end wall is set to a shape that is narrower at the top and wider at the bottom, which can improve the thrust resistance of the second end wall and reduce the damage to the second end wall when the socket and plug are forcibly fastened.

[0092] In one optional implementation, the second terminal group includes multiple rows of second terminals, each row including multiple second inner terminals and multiple second outer terminals. The contact portions of the multiple second inner terminals are flush, and the contact portions of the multiple second outer terminals are also flush. The contact portions of the second inner terminals and the second outer terminals are spaced apart along the width direction of the second base. In the same row of second terminals, the second outer terminals and the second inner terminals are arranged alternately along the length direction of the second base. Viewed directly from the slot of the second base, the contact portions of the second inner terminals and the second outer terminals in the same row of second terminals are arranged in an alternating concave-convex pattern. This prevents the first and second terminals from misaligning after the socket and plug are engaged, thus preventing circuit malfunction or short circuit risks. The sockets and plugs in the ultra-miniature connector can be quickly pre-positioned and accurately engaged, reducing damage caused by forcibly engaging the socket and plug when there is a large engagement deviation.

[0093] In one alternative implementation, the contact portion of the second inner terminal and the contact portion of the second outer terminal can be generally U-shaped.

[0094] In one alternative implementation, when the first base and the second base are plugged in, the contact portions of the first inner terminal and the second inner terminal abut against each other in a one-to-one manner, and the contact portions of the first outer terminal and the second outer terminal abut against each other in a one-to-one manner. The U-shaped contact portion of the second inner terminal is inserted into the corresponding contact portion (U-shaped slot) of the first inner terminal. The U-shaped contact portion of the second outer terminal is inserted into the corresponding contact portion (U-shaped slot) of the first outer terminal. This achieves both mechanical and electrical connection between the socket and the plug.

[0095] In one alternative implementation, in two adjacent rows of second terminals, the second inner terminal in one row and the second outer terminal in the other row are arranged in a one-to-one correspondence.

[0096] In one alternative implementation, in the plug, the tail portion and contact portion of the second inner terminal are positioned opposite each other along the width direction of the second base. The tail portion and contact portion of the second outer terminal are also positioned opposite each other. The tail portion of the second inner terminal is located inside the second base along the width direction of the second base, and may be located on the bottom surface of the recess. The tail portion of the second outer terminal is located outside the second base along the width direction of the second base, and may be located outside the second sidewall. The tail portions of the second inner terminal and the second outer terminal face opposite directions along the width direction of the second base. The second terminals in the same row can be reliably soldered onto the second electronic component, and adjacent second terminals are less prone to solder bridging during soldering.

[0097] In one alternative implementation, the second inner terminals and the second outer terminals in the same row of second terminals are staggered, and the distance between adjacent second inner terminals and second outer terminals located on the inner and outer sides of the second base can be reduced by half, thereby reducing the length or area of ​​the plug. This achieves an ultra-miniature connector.

[0098] In one alternative implementation, the number of first terminal rows in the first terminal group and the number of second terminal rows in the second terminal group are equal, thus ensuring compatibility between the two. For example, both the first and second terminals have two rows, or both have three rows.

[0099] Thirdly, embodiments of this application provide an electrical connector, including the aforementioned socket and plug. The socket and plug are mated together. The socket includes a first base and a first terminal group, the first terminal group being disposed on the first base. The plug includes a second base and a second terminal group, the second terminal group being disposed on the second base. When the first base and the second base are mated together, the first terminal group and the second terminal group abut against each other.

[0100] In one alternative implementation, a plurality of first terminals in the socket can be soldered to a first electronic component, and a plurality of second terminals in the plug can be soldered to a second electronic component. This electrical connector can function as a board-to-board connector, allowing for both mechanical and electrical connections between the socket and the plug, thus achieving an electrical connection between the first and second electronic components.

[0101] Fourthly, embodiments of this application provide an electronic component, including a first electronic component, a second electronic component, and the aforementioned electrical connector, with a socket connected to the first electronic component and a plug connected to the second electronic component.

[0102] Fifthly, embodiments of this application provide an electronic component, including a first electronic component, a socket, and the aforementioned plug component, wherein the socket is connected to the first electronic component.

[0103] The first and second electronic components are detachably connected via an electrical connector. When the socket and plug are inserted / engaged, the first and second electronic components are electrically connected, enabling the transmission of electrical signals and / or electrical energy. The plug can be soldered to the first electronic component, and the socket can be soldered to the second electronic component.

[0104] In one alternative implementation, the first electronic component may include a flexible circuit board and a reinforcing plate stacked on top of each other. The reinforcing plate can improve structural strength and can be a steel sheet, etc. Alternatively, the first electronic component may be a rigid circuit board. Alternatively, the first electronic component may be an electronic module. The first electronic component in the above embodiments can be equipped with a plug. The electronic module may be a display module, a speaker module, etc.

[0105] In one alternative implementation, the second electronic component may include a flexible circuit board and a reinforcing plate stacked on top of each other. The reinforcing plate can improve structural strength and can be a steel sheet, etc. Alternatively, the second electronic component may be a rigid circuit board. Alternatively, the second electronic component may be an electronic module. The second electronic component in the above embodiments can be equipped with a socket. The electronic module may be a camera module, a speaker module, etc.

[0106] In one alternative implementation, a locking element is also included to keep the socket and plug plugged in place. The locking element ensures a reliable connection between the socket and plug, preventing them from coming loose and improving connection reliability.

[0107] In one alternative implementation, the locking element includes a pressing part and a connecting part, which are connected. The pressing part abuts against the side of the second electronic component opposite to the plug, and the connecting part is assembled to the first electronic component. This achieves a reliable connection between the socket and the plug. The connecting part and the first electronic component can be connected by fasteners (such as screws), clips, adhesives, or other methods.

[0108] Sixthly, embodiments of this application provide a device including the aforementioned socket, or the aforementioned plug component, or the aforementioned electrical connector, or the aforementioned electronic component.

[0109] This application provides a socket, plug, electrical connector, electronic component, and device to solve the problem that the socket and plug are easily damaged when forcibly fastened due to a misalignment.

[0110] The embodiments of this application adopt the following technical solutions:

[0111] In a seventh aspect, embodiments of this application provide a socket for mating with a plug; the socket includes a first base and a first terminal group, the first terminal group being disposed on the first base. The socket has a pair of first reinforcing portions, the pair of first reinforcing portions being distributed at opposite ends along the length direction of the first base. Along the length direction of the first base, the bottom dimension of the first reinforcing portion is larger than the top dimension of the first reinforcing portion.

[0112] The socket provided in this application embodiment has a first reinforcing part that enhances the structural strength of the socket end, reducing damage to the socket end during the socket and plug insertion process. During the socket and plug insertion process, the first reinforcing part provides a guiding function, ensuring smooth alignment and insertion of the socket and plug. When the slot of the first base faces upwards, the first reinforcing part is configured as a shape that is narrower at the top and wider at the bottom, such as a trapezoid or dam shape. This effectively improves the thrust resistance of the first reinforcing part, reducing the likelihood of damage to the first reinforcing part when the socket and plug are forcibly fastened due to large engagement deviations.

[0113] In one alternative implementation, the first reinforcement includes a first end wall and a first fitting, the first fitting covering at least a portion of the surface of the first end wall.

[0114] In one alternative implementation, the first reinforcing part can be a first end wall, and no first fitting is provided outside the first end wall. The first end wall is made of a high-strength material (such as ceramic).

[0115] In one alternative implementation, the first reinforcing part is cut with a vertical plane in the width direction of the first base to form a cross-section. The outer surface of the first reinforcing part can be presented in a variety of predetermined shapes, such as an inclined line extending from the bottom towards the central island, an inclined line extending from the bottom away from the central island, or an outward convex arc line away from the central island.

[0116] In one alternative implementation, on the vertical plane of the height direction of the first base, the outer side projection of the first reinforcement is at least partially convex arc-shaped.

[0117] In one alternative implementation, the first end wall includes a main body segment and a pair of auxiliary segments, the main body segment being located at the end of the first base along its length; the pair of auxiliary segments are respectively connected to both ends of the main body segment; the first fitting includes a main body portion and a pair of auxiliary portions, the pair of auxiliary portions being respectively connected to both ends of the main body portion, the main body portion covering at least a portion of the surface of the main body segment, and the auxiliary portions covering at least a portion of the surface of the auxiliary segments.

[0118] In one alternative implementation, the first outer wall of the first fitting is a smooth surface, and the first outer wall covers the outer surface of the first end wall, which can better disperse internal stress and improve structural strength.

[0119] In one alternative implementation, the bottom thickness of the appendage is greater than the top thickness. The appendage is designed with a shape that is narrower at the top and wider at the bottom (such as a trapezoid or dam shape) to enclose the appendage segment, which can improve the thrust resistance of the appendage segment.

[0120] In one alternative implementation, the bottom thickness of the appendix is ​​equal to the top thickness of the appendix.

[0121] In one alternative implementation, the outer wall of the main body is a continuous wall surface. In another alternative implementation, the outer wall of the main body is a discontinuous wall surface. In another alternative implementation, the outer wall of the accessory portion can be continuous or discontinuous. In one alternative implementation, the inner wall of the main body and the inner wall of the accessory portion are connected. In another alternative implementation, the inner walls of the main body and the inner walls of the accessory portion are spaced apart.

[0122] In one alternative implementation, the first base includes a pair of first sidewalls extending along the length of the first base, and the pair of first sidewalls being spaced apart along the width of the first base. The first base also includes a pair of outer sidewalls spaced apart along the width of the first base, and the pair of first sidewalls being located between the pair of outer sidewalls.

[0123] In one alternative implementation, the socket has a positioning part; the plug and electronic components are connected; the positioning part can be inserted into the positioning hole of the electronic component. Before the socket and plug are engaged, the positioning part of the socket is inserted into the positioning hole of the electronic component, realizing rapid pre-positioning of the socket and plug, minimizing the deviation before engagement, and thus ensuring accurate engagement and mating of the socket and plug.

[0124] In one alternative implementation, the top surface of the positioning part is higher than the top surface of the first base in the height direction of the first base.

[0125] In one alternative implementation, the positioning portion is a protrusion formed on at least a portion of the top of at least one first fitting. Fabricating the protrusion and the first fitting as a single unit, such as a metal part manufactured using a drawing process, facilitates forming and provides good structural strength.

[0126] In one alternative implementation, the protrusion covers the filling material portion. The filling material portion is connected to the top of the first end wall.

[0127] In one alternative implementation, the protrusion may not have a filling material section inside. The protrusion is part of the first fitting.

[0128] In one alternative implementation, the inner side of the protrusion has a first guide surface; the first guide surface is used to mate with the second end wall of the plug.

[0129] In one alternative implementation, the positioning part is a boss located on the first base. The positioning part can be located on the first end wall of the first base; the positioning part can be located on the central island portion of the first base; or the positioning part can be located on the first side wall of the first base. Positioning holes are provided at corresponding positions on the electronic component (second electronic component). By engaging the boss on the first base with the positioning holes, the pre-positioning of the socket and plug can be achieved.

[0130] In one alternative implementation, the positioning part can be assembled into the first base, or the positioning part can be integrally injection molded into the first base.

[0131] In one alternative implementation, the boss is a column extending along the height direction of the first base.

[0132] In one alternative implementation, the boss is connected to the first base and passes through the first fitting, making it easy to manufacture and assemble.

[0133] In one alternative implementation, the edge of the insertion end of the positioning part inserted into the positioning hole is chamfered.

[0134] In one alternative implementation, the wall of the positioning hole is chamfered, and the inner diameter of the positioning hole gradually decreases in the direction in which the positioning part is inserted into the positioning hole.

[0135] In one alternative implementation, the first reinforcing part is a first end wall, meaning that no first fitting is provided outside the first end wall. The positioning part can be a boss located on at least a portion of the top of the first end wall. The inner surface of the boss has a second guide surface; the second guide surface is used to mate with the second end wall of the plug.

[0136] In one optional implementation, the first terminal group includes multiple rows of first terminals, each row of first terminals including multiple first inner terminals and multiple first outer terminals. The contact portions of the multiple first inner terminals are flush, and the contact portions of the multiple first outer terminals are flush. The contact portions of the first inner terminals and the contact portions of the first outer terminals are spaced apart along the width direction of the first base. In the same row of first terminals, the first inner terminals and the first outer terminals are arranged alternately along the length direction of the first base.

[0137] In one alternative implementation, the contact portion of the first inner terminal and the contact portion of the first outer terminal may have a generally U-shaped slot.

[0138] In one alternative implementation, in two adjacent rows of first terminals, along the width direction of the first base, the first inner terminal in one row and the first outer terminal in the other row are arranged in a one-to-one correspondence.

[0139] In one alternative implementation, along the width direction of the first base, the tail portion and contact portion of the first inner terminal are positioned opposite each other, and the tail portion and contact portion of the first outer terminal are also positioned opposite each other. The tail portion of the first inner terminal is located inside the first base along the width direction of the first base. The tail portion of the first outer terminal is located outside the first base along the width direction of the first base. The tail portions of the first inner terminal and the first outer terminal face opposite directions along the width direction of the first base. The first terminals in the same row can be reliably soldered onto the first electronic component, and adjacent first terminals are less prone to solder joints during soldering.

[0140] In one alternative implementation, the first inner terminals and the first outer terminals in the same row of first terminals are arranged alternately, with their tails located correspondingly on the inner and outer sides of the first base. The spacing between adjacent first inner terminals and first outer terminals can be reduced by half, thereby reducing the length or area of ​​the socket. This achieves an ultra-miniature connector.

[0141] In one alternative implementation, the number of first terminal rows in the first terminal group and the number of second terminal rows in the second terminal group are equal, thus making them compatible.

[0142] Eighthly, embodiments of this application provide a plug for mating with a socket. The plug includes a second base and a second terminal group, the second terminal group being disposed on the second base. The second base has a pair of second reinforcing portions, the pair of second reinforcing portions being distributed at opposite ends along the length direction of the second base. Along the length direction of the second base, the bottom dimension of the second reinforcing portion is larger than the top dimension of the second reinforcing portion.

[0143] The plug provided in this application embodiment has a second reinforcing part that enhances the structural strength of the plug end, reducing damage to the plug end during the socket and plug insertion process. During the socket and plug insertion process, the second reinforcing part provides a guiding function, ensuring smooth alignment and insertion of the socket and plug. When the slot of the second base faces upwards, the second reinforcing part is configured as a shape that is narrower at the top and wider at the bottom, such as a trapezoid or dam shape. This effectively improves the thrust resistance of the second reinforcing part, reducing damage to the second reinforcing part caused by forcibly fastening the socket and plug when there is a large misalignment.

[0144] In one alternative implementation, the second base in the plug may be made of an insulating material (such as plastic). The second terminal group has multiple second terminals, which may be made of a conductive metal (such as copper).

[0145] In one alternative implementation, the second base includes a pair of second sidewalls and a pair of second endwalls. The second sidewalls extend along the length of the second base, and the pairs of second sidewalls are spaced apart along the width of the second base. The pairs of second endwalls are distributed at opposite ends along the length of the second base. The two second sidewalls and the two second endwalls can be arranged in a generally rectangular shape. A groove is formed between the two second sidewalls and the two second endwalls, and the groove has an opening.

[0146] In one alternative implementation, the second end wall and the second side wall can be connected to the same side of the second base plate.

[0147] In one alternative implementation, the second end wall and the second side wall are directly connected.

[0148] In one alternative implementation, the second reinforcement includes a second end wall and a second fitting, the second fitting covering at least a portion of the surface of the second end wall.

[0149] In one alternative implementation, the second reinforcing part is a second end wall, that is, no second fitting is provided outside the second end wall.

[0150] In one alternative implementation, the second reinforcing part includes a second end wall and a second fitting, with the second fitting covering the second end wall. When the slot of the second base faces upward, the second fitting is configured to be narrower at the top and wider at the bottom, covering the surface of the second end wall. This improves the thrust resistance of the second fitting and reduces damage to the second fitting and the second end wall when the socket and plug are forcibly fastened.

[0151] In one alternative implementation, the second reinforcing part is a second end wall. When the slot of the second base faces upward, the second end wall is set to a shape that is narrower at the top and wider at the bottom, which can improve the thrust resistance of the second end wall and reduce the damage to the second end wall when the socket and plug are forcibly fastened.

[0152] In one optional implementation, the second terminal group includes multiple rows of second terminals, each row including multiple second inner terminals and multiple second outer terminals. The contact portions of the multiple second inner terminals are flush, and the contact portions of the multiple second outer terminals are flush. The contact portions of the second inner terminals and the contact portions of the second outer terminals are spaced apart along the width direction of the second base. In the same row of second terminals, the second outer terminals and the second inner terminals are arranged alternately along the length direction of the second base.

[0153] In one alternative implementation, the contact portion of the second inner terminal and the contact portion of the second outer terminal can be generally U-shaped.

[0154] In one alternative implementation, in two adjacent rows of second terminals, the second inner terminal in one row and the second outer terminal in the other row are arranged in a one-to-one correspondence.

[0155] In one alternative implementation, the tail portion and contact portion of the second inner terminal are positioned opposite each other along the width direction of the second base. The tail portion and contact portion of the second outer terminal are also positioned opposite each other. The tail portion of the second inner terminal is located inside the second base along the width direction of the second base. The tail portion of the second outer terminal is located outside the second base along the width direction of the second base. The tail portions of the second inner terminal and the second outer terminal face opposite directions along the width direction of the second base. The second terminals in the same row can be reliably soldered onto the second electronic component, and adjacent second terminals are less prone to solder joints during soldering.

[0156] In one alternative implementation, the second inner terminals and the second outer terminals in the same row of second terminals are staggered, and the distance between adjacent second inner terminals and second outer terminals located on the inner and outer sides of the second base can be reduced by half, thereby reducing the length or area of ​​the plug. This achieves an ultra-miniature connector.

[0157] In one alternative implementation, the number of first terminal rows in the first terminal group and the number of second terminal rows in the second terminal group are equal, thus making them compatible.

[0158] Ninthly, embodiments of this application provide an electrical connector, including a socket and a plug. The socket and plug are mated together.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0199] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0200] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0201] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0202] Referring to Figure 1(a), an electrical connector 1 in the related art includes a socket 2 and a plug 3. The socket 2 has two rows of first terminals 2a, each with oppositely distributed contact portions 2b and tail portions 2c. The contact portions 2b of the same row of first terminals 2a are flush and have generally U-shaped slots. The tail portions 2c of the same row of first terminals 2a are flush and located outside the width direction of the socket base 2d, and are soldered to a first circuit board (not shown). Socket fittings 2e are distributed at opposite ends along the length direction of the socket 2. The plug 3 has two rows of second terminals 3a, each with oppositely distributed contact portions 3b and tail portions 3c. The contact portions 3b of the same row of second terminals 3a are flush and have generally U-shaped shapes. The tail portions 3c of the same row of second terminals 3a are flush and located outside the width direction of the plug base 3d, and are soldered to a second circuit board (not shown). The plug 3 has plug fittings 3e distributed at opposite ends along its length. During the engagement of the socket 2 and the plug 3, the socket fittings 2e and the plug fittings 3e abut against each other, and the contact portions 2b of the first terminal 2a and the second terminal 3a abut against each other one-to-one. The U-shaped contact portion 3b is inserted into the U-shaped slot of the contact portion 2b. This achieves the electrical connection between the first circuit board and the second circuit board.

[0203] The adjacent terminal spacing A0 refers to the distance between the center lines of two adjacent terminals. The smaller the adjacent terminal spacing A0, the smaller the length and area of ​​the electrical connector 1. By reducing the adjacent terminal spacing A0, the area occupied by the electrical connector 1 on the circuit board can be reduced. If the adjacent terminal spacing A0 is too close, it can cause solder bridging during the soldering process, making it difficult to further reduce the adjacent terminal spacing A0. Under current soldering technology, the minimum adjacent terminal spacing A0 is approximately 0.30 millimeters (mm).

[0204] Referring to Figure 1(b), the socket fitting 2e and plug fitting 3e work together to provide a certain guiding effect, enabling the socket 2 and plug 3 to engage. The contact arc 2f of the socket fitting 2e is relatively small, and the guiding distance B0 is approximately 0.15 mm to 0.25 mm, resulting in minimal guiding effect on the plug base 3d / plug fitting 3e. The guiding distance B0 is the distance at the contact arc 2f of the fittings in the insertion direction of the socket 2 and plug 3.

[0205] The miniaturized electrical connector 1 results in lower structural strength for the fittings and terminals. During the blind-clamping process of the socket 2 and plug 3, the clamping deviation is significant. Forced clamping may cause the fittings / base to collapse and be damaged, or prevent clamping altogether. As shown in Figure 1(b), during the clamping process, the socket fitting 2e and plug fitting 3e may be deformed by compression. For example, the left socket fitting 2e may be compressed and bulge outwards to the left, becoming the socket fitting 2e' shown by the double-dotted line. The right plug fitting 3e may be compressed and deformed to the right, becoming the plug fitting 3e' shown by the double-dotted line.

[0206] Referring to Figure 1(c), during the blind snapping process of socket 2 and plug 3, an excessive length deviation C is likely to occur between socket 2 and plug 3, causing the first terminal 2a and the second terminal 3a to not be connected one-to-one. Instead, two adjacent second terminals 3a are connected by the same first terminal 2a, which may cause circuit malfunction or short circuit risk.

[0207] Referring to Figures 2(a) to (c), this embodiment of the application provides an electronic component 1000, including a first electronic component 200, a second electronic component 300, and an electrical connector 100. The electrical connector 100 includes a socket 10 and a plug 20. The socket 10 is connected to the first electronic component 200, and the plug 20 is connected to the second electronic component 300. The first electronic component 200 and the second electronic component 300 are detachably connected via the electrical connector 100. When the socket 10 and the plug 20 are plugged in / out, the first electronic component 200 and the second electronic component 300 are electrically connected, enabling the transmission of electrical signals and / or electrical energy. The plug 20 can be soldered to the first electronic component 200, and the socket 10 can be soldered to the second electronic component 300.

[0208] There are several possible implementations for the first electronic component 200. In some embodiments, referring to FIG2(a), the first electronic component 200 may include a flexible circuit board 201 and a reinforcing plate 202 stacked together. The reinforcing plate 202 can improve structural strength and may be a steel sheet, etc. Alternatively, referring to FIG2(b) and (c), the first electronic component 200 may be a rigid circuit board 203. Alternatively, the first electronic component 200 may be an electronic module. The first electronic component 200 in the above embodiments can be equipped with a plug 20. The electronic module may be a display module, a speaker module, etc.

[0209] There are several possible implementations for the second electronic component 300. In some embodiments, referring to Figures 2(a) and (b), the second electronic component 300 may include a flexible circuit board 301 and a reinforcing plate 302 stacked together. The reinforcing plate 302 can improve structural strength and may be a steel sheet, etc. Alternatively, referring to Figures 2(b) and (c), the second electronic component 300 may be a rigid circuit board 303. Alternatively, the second electronic component 300 may be an electronic module. The second electronic component 300 in the above embodiments can be equipped with a socket 10. The electronic module may be a camera module, a speaker module, etc.

[0210] For example, referring to Figure 2(a), the first electronic component 200 includes a flexible circuit board 201 and a reinforcing plate 202 stacked on top of each other, and the second electronic component 300 includes a flexible circuit board 301 and a reinforcing plate 302 stacked on top of each other.

[0211] For example, referring to Figure 2(b), the first electronic component 200 is a rigid circuit board 203, and the second electronic component 300 includes a flexible circuit board 301 and a reinforcing plate 302 stacked on top of each other.

[0212] For example, referring to (c) in Figure 2, the first electronic component 200 is a rigid circuit board 203, and the second electronic component 300 is a rigid circuit board 303.

[0213] For example, both the first electronic component 200 and the second electronic component 300 are electronic modules.

[0214] For example, the first electronic component 200 is a rigid circuit board 203, and the second electronic component 300 is an electronic module.

[0215] In some embodiments, referring to FIG3, a locking member 400 is further included for keeping the socket 10 and the plug 20 plugged in place. The locking member 400 ensures a reliable connection between the socket 10 and the plug 20, preventing them from coming loose and improving connection reliability.

[0216] For example, the locking member 400 includes a pressing part 401 and a connecting part 402, which are connected. The pressing part 401 abuts against the side of the second electronic component 300 opposite to the plug 20, and the connecting part 402 is assembled to the first electronic component 200. This achieves a reliable connection between the socket 10 and the plug 20. The connecting part 402 and the first electronic component 200 can be connected by fasteners 403 (such as screws), clips, adhesives, etc. The locking member 400 can be formed by bending a steel sheet.

[0217] Referring to Figures 4 to 7, this application embodiment provides an electrical connector 100, including a socket 10 and a plug 20. The socket 10 and the plug 20 are inserted into each other. The socket 10 includes a first base 11 and a first terminal group 12, with the first terminal group 12 disposed on the first base 11. The plug 20 includes a second base 21 and a second terminal group 22, with the second terminal group 22 disposed on the second base 21. When the first base 11 and the second base 21 are inserted into each other, the first terminal group 12 and the second terminal group 22 abut against each other.

[0218] In the socket 10, the first base 11 may be made of an insulating material (such as plastic). The first terminal group 12 has a plurality of first terminals 12a, which may be made of a conductive metal (such as copper). The plurality of first terminals 12a are fixed to the first base 11 and are insulated from each other. The plurality of first terminals 12a may serve as signal terminals.

[0219] In the plug 20, the second base 21 may be made of an insulating material (such as plastic). The second terminal group 22 has a plurality of second terminals 22a, which may be made of a conductive metal (such as copper). The plurality of second terminals 22a are fixed to the second base 21 and are insulated from each other. The plurality of second terminals 22a may serve as signal terminals.

[0220] The multiple first terminals 12a in the socket 10 can be soldered to the first electronic component 200, and the multiple second terminals 22a in the plug 20 can be soldered to the second electronic component 300. The electrical connector 100 can be used as a board-to-board connector, and the socket 10 and the plug 20 can be mechanically and electrically connected to achieve an electrical connection between the first electronic component 200 and the second electronic component 300.

[0221] In some embodiments, referring to Figures 9, 10, and 11, in the socket 10, the first base 11 includes a pair of first sidewalls 111 and a pair of first endwalls 112. The first sidewalls 111 extend along the length direction X1 of the first base 11, and the pair of first sidewalls 111 are spaced apart along the width direction Y1 of the first base 11. The pair of first endwalls 112 are distributed at opposite ends of the length direction X1 of the first base 11. The two first sidewalls 111 and the two first endwalls 112 may be arranged in a generally rectangular shape. The first base 11 also includes a central island portion 113, which is located between the two first endwalls 112 and also between the two first sidewalls 111. An annular groove 114 is formed between the two first sidewalls 111, the two first endwalls 112, and the central island portion 113, and the annular groove 114 has a notch 114a.

[0222] The first base 11 also includes a first base plate 115, and a first end wall 112, a first side wall 111 and a central island portion 113 are connected to the same side of the first base plate 115.

[0223] The first base 11 and the first terminal group 12 in the socket 10 can be an integral structure. During manufacturing, multiple first terminals 12a are first stamped and then an insert injection molding process is used to tightly bond the material of the first base 11 with the first terminals 12a to form an integral structure.

[0224] The first base 11 and the first terminal group 12 can also be an assembly structure, in which the first base 11 and the first terminal group 12 are first manufactured, and then the first terminal group 12 is inserted into the first base 11.

[0225] In some embodiments, referring to Figures 9, 10, and 12, in the plug 20, the second base 21 includes a pair of second sidewalls 211 and a pair of second endwalls 212. The second sidewalls 211 extend along the length direction X2 of the second base 21, and the pairs of second sidewalls 211 are spaced apart along the width direction Y2 of the second base 21. The pairs of second endwalls 212 are distributed at opposite ends along the length direction X2 of the second base 21. The two second sidewalls 211 and the two second endwalls 212 may be arranged in a generally rectangular shape. A groove 213 is formed between the two second sidewalls 211 and the two second endwalls 212, and the groove 213 has a slot 213a.

[0226] The second end wall 212 and the second side wall 211 can be connected to the same side of the second base plate 214. Alternatively, the second base plate 214 can be omitted, and the second end wall 212 and the second side wall 211 can be directly connected.

[0227] The second base 21 and the second terminal group 22 in the plug 20 can be an integral structure. During manufacturing, multiple second terminals 22a are first stamped, and then an insert injection molding process is used to tightly bond the material of the second base 21 with the second terminals 22a to form an integral structure.

[0228] The second base 21 and the second terminal group 22 can also be an assembly structure, in which the second base 21 and the second terminal group 22 are first made, and then the second terminal group 22 is inserted into the second base 21.

[0229] During the insertion and connection of the socket 10 and the plug 20, the second sidewall 211 and the second endwall 212 of the second base 21 can be inserted into the annular groove 114 of the first base 11. The second sidewall 211 and the second endwall 212 surround the central island portion 113 of the first base 11, and the central island portion 113 of the first base 11 can be inserted into the groove 213 of the second base 21. When the socket 10 and the plug 20 are fully inserted / closed, the first sidewall 111 and the second sidewall 211 push against each other in a corresponding manner, and the first endwall 112 and the second endwall 212 push against each other in a corresponding manner.

[0230] The first end wall 112 and the second end wall 212 push against each other, meaning there is a mutual pushing force between them. They do not necessarily have direct contact; instead, there are other parts or structures between them. For example, the outer surface of the first end wall 112 can cover the first fitting 14, and the outer surface of the second end wall 212 can cover the second fitting 23. When the socket 10 and the plug 20 are connected, the first end wall 112 and the second end wall 212 push against each other, and the first fitting 14 and the second fitting 23 are located between the first end wall 112 and the second end wall 212, abutting against each other.

[0231] Referring to Figures 4 to 7, this embodiment of the application provides a socket 10 for mating with a plug 20. The plug 20 is used to connect to an electronic component (such as a second electronic component 300). The socket 10 includes a first base 11 and a first terminal group 12. The socket 10 has a positioning portion 13. Referring to Figures 8(a) to (d), the positioning portion 13 is used to be inserted into a positioning hole 311 of the electronic component (second electronic component 300).

[0232] The positioning hole 311 of the electronic component (second electronic component 300) can be a through hole that penetrates the electronic component or a blind hole that does not penetrate the electronic component.

[0233] The socket 10 provided in this embodiment has a positioning part 13, and the electronic component (second electronic component 300) connected to the plug 20 has a positioning hole 311. As shown in Figures 8(a) and (b), before the socket 10 and the plug 20 are fastened together, the positioning part 13 of the socket 10 is inserted into the positioning hole 311 of the electronic component (second electronic component 300) to achieve rapid pre-positioning of the socket 10 and the plug 20, so that the deviation before fastening is small, as shown in Figures 8(c) and (d), thereby enabling the socket 10 and the plug 20 to be accurately fastened together and reducing the damage caused by forcibly fastening the socket 10 and the plug 20.

[0234] In some embodiments, referring to FIG8(a), in the height direction Z1 of the first base 11, the top surface 13a of the positioning part 13 is higher than the top surface 11a of the first base 11. The height direction Z1 of the first base 11 is the direction in which the socket 10 and the plug 20 are inserted. When the socket 10 and the plug 20 are inserted, the height direction Z1 of the first base 11 and the height direction Z2 of the second base 21 can be parallel. Referring to FIG4 and FIG8(a), when the slot 114a of the first base 11 faces upward, the top surface 13a of the positioning part 13 is the highest position of the positioning part 13, and the top surface 11a of the first base 11 is the highest position of the first base 11.

[0235] This facilitates the insertion of the positioning part 13 of the socket 10 into the positioning hole 311 of the electronic component (second electronic component 300), enabling the socket 10 and plug 20 to be quickly pre-positioned, thus minimizing the deviation before engagement.

[0236] In some embodiments, referring to FIG4, the second electronic component 300 includes a flexible circuit board 301 and a reinforcing plate 302 stacked on top of each other. A plug 20 is connected to the flexible circuit board 301, and the reinforcing plate 302 is located on the side of the flexible circuit board 301 opposite to the plug 20. Openings may be provided at corresponding positions on the flexible circuit board 301 and the reinforcing plate 302, and the two openings communicate to form a positioning hole 311.

[0237] In some embodiments, referring to Figures 4 and 8, the socket 10 has a pair of first reinforcing portions 10a, which are distributed at opposite ends along the longitudinal direction X1 of the first base 11. The first reinforcing portions 10a can enhance the structural strength of the end position of the socket 10, reducing damage to the end of the socket 10 caused by the insertion process of the socket 10 and the plug 20. During the insertion and mating process of the socket 10 and the plug 20, the first reinforcing portions 10a can provide a certain guiding effect, so that the socket 10 and the plug 20 can be smoothly aligned and inserted.

[0238] In some embodiments, referring to Figures 4, 8 to 10, and 15 to 17, the first reinforcing portion 10a includes a first end wall 112 and a first fitting 14, the first fitting 14 covering at least a portion of the surface of the first end wall 112. The first fitting 14 can improve the structural strength at the location of the first end wall 112 and reduce the possibility of contact wear and crush damage to the first end wall 112.

[0239] For example, the first fitting 14 may be made of metal (such as copper), may be made by drawing process, is easy to form, and has good structural strength.

[0240] For example, the first base 11 can be injection molded with the first fitting 14 as an insert, so that the material of the first base 11 and the first fitting 14 are tightly combined to form an integral structure.

[0241] For example, the first fitting 14 may be assembled onto the first end wall 112 by insert or other means. There may be a gap between the first end wall 112 and the first fitting 14.

[0242] In other embodiments, the first reinforcing part 10a can be a first end wall 112, that is, the first end wall 112 is not provided with a first fitting 14. The first end wall 112 is made of a high-strength material (such as ceramic), so there is no need to provide a first fitting 14.

[0243] In order to improve the structural strength of the first reinforcing part 10a, in some embodiments, referring to Figures 13 and 18, the bottom 10b dimension D1 of the first reinforcing part 10a is larger than the top 10c dimension D2 of the first reinforcing part 10a in the length direction X1 of the first base 11.

[0244] The bottom 10b of the first reinforcing part 10a is the lowest position of the first reinforcing part 10a when the slot 114a of the first base 11 faces upwards. The dimension D1 of the bottom 10b of the first reinforcing part 10a refers to the dimension of the bottom 10b of the first reinforcing part 10a along the length X1 of the first base 11. The top 10c of the first reinforcing part 10a is the highest position of the first reinforcing part 10a when the slot 114a of the first base 11 faces upwards. The dimension D2 of the top 10c of the first reinforcing part 10a refers to the dimension of the top 10c of the first reinforcing part 10a along the length X1 of the first base 11.

[0245] When the slot 114a of the first base 11 faces upward, the first reinforcing part 10a is configured to be narrower at the top and wider at the bottom, such as a trapezoid or dam shape. The first reinforcing part 10a is configured with a thicker bottom, which can better improve the thrust resistance of the first reinforcing part 10a, reduce the possibility of damage to the first reinforcing part 10a when the socket 10 and plug 20 are forcibly fastened due to a large fastening deviation, and improve reliability.

[0246] For example, the first reinforcing part 10a includes a first end wall 112 and a first fitting 14, the first fitting 14 covering the first end wall 112. The first end wall 112 is configured to be narrower at the top and wider at the bottom (such as a trapezoid or dam shape), and the first fitting 14 is also configured to be narrower at the top and wider at the bottom to cover the first end wall 112. This can improve the thrust resistance of the first end wall 112 and reduce the damage to the first fitting 14 and the first end wall 112 when the socket 10 and the plug 20 are forcibly fastened.

[0247] For example, the first reinforcing part 10a is a first end wall 112, which is configured to be narrow at the top and wide at the bottom (such as trapezoidal or dam-shaped), which can improve the thrust resistance of the first end wall 112 and reduce the damage to the first end wall 112 when the socket 10 and plug 20 are forcibly fastened.

[0248] In some embodiments, referring to Figures 13 and 18, the first reinforcing portion 10a is cut along a vertical plane (i.e., the plane containing X1 and Z1) in the width direction of the first base 11. The outer surface 10d of the first reinforcing portion 10a can have various predetermined shapes, such as an inclined line extending from the bottom towards the central island portion 113, an inclined line extending from the bottom away from the central island portion 113, or an outwardly convex arc line away from the central island portion 113. Making the bottom 10b of the first reinforcing portion 10a thicker can improve the lateral strength of the first reinforcing portion 10a.

[0249] To enhance the structural strength of the first reinforcing part 10a, in some embodiments, referring to Figures 4 and 6, the projection of the outer surface 10d of the first reinforcing part 10a onto the vertical plane (i.e., the plane containing X1 and Y1) in the height direction Z1 of the first base 11 is at least partially convex arc-shaped. The projection of the outer surface 10d of the first reinforcing part 10a can be understood as the pattern presented by the cross-section formed by cutting the first reinforcing part 10a with the vertical plane (i.e., the plane containing X1 and Y1) in the height direction Z1 of the first base 11. The outer surface 10d of the first reinforcing part 10a is convex arc-shaped, and this convex arc-shaped projection is outward from the central island portion 113.

[0250] During the insertion of the first base 11 and the second base 21, the first end wall 112 and the second end wall 212 push against each other, causing compression deformation inside the first end wall 112. The outwardly convex arc-shaped first end wall 112 can better disperse the internal stress, improve the structural strength of the first end wall 112, and reduce the possibility of the first end wall 112 being crushed and damaged. The outwardly convex arc shape can be a circular arc, an elliptical arc, or a combination of multiple outwardly convex arc shapes.

[0251] For example, on the vertical plane of the height direction Z1 of the first base 11 (i.e., the plane containing X1 and Y1), the projection of the outer surface 10d of the first reinforcing part 10a is entirely outwardly convex arc-shaped. The first reinforcing part 10a with the outwardly convex arc-shaped outer surface 10d can effectively disperse internal stress and improve the structural strength of the first reinforcing part 10a.

[0252] For example, referring to Figure 9, the first fitting 14 covers the outer surface of the first end wall 112, and the outer surface of the first outer wall 142 of the first fitting 14 is the outer surface 10d of the first reinforcing part 10a. The first outer wall 142 of the first fitting 14 is convex arc-shaped.

[0253] For example, the first reinforcing part 10a is a first end wall 112, and the outer surface of the first end wall 112 is the outer surface 10d of the first reinforcing part 10a. The outer surface of the first end wall 112 is convex arc-shaped.

[0254] In some embodiments, referring to Figures 9, 15 to 19, the first end wall 112 includes a main body segment 1121 and a pair of auxiliary segments 1122. The main body segment 1121 is located at the end of the first base 11 in the longitudinal direction X1. The pair of auxiliary segments 1122 are respectively connected to both ends of the main body segment 1121. The first fitting 14 includes a main body portion 144 and a pair of auxiliary portions 145. The pair of auxiliary portions 145 are respectively connected to both ends of the main body portion 144. The main body portion 144 covers at least a portion of the surface of the main body segment 1121, and the auxiliary portions 145 cover at least a portion of the surface of the auxiliary segments 1122. By covering the main body segment 1121 with the main body portion 144, the structural strength of the main body segment 1121 is improved. By covering the auxiliary segments 1122 with the auxiliary portions 145, the structural strength of the auxiliary segments 1122 is improved. The first fitting 14 and the first end wall 112 are less likely to be damaged when the socket 10 and the plug 20 are forcibly fastened.

[0255] The main body segment 1121 can be arc-shaped, straight, semi-circular, etc. The auxiliary segment 1122 can be straight, etc., and can extend along the length direction X1 or other directions of the first base 11. The auxiliary segment 1122 of the first end wall 112 can be connected to the first side wall 111 to improve the structural strength. The main body 144 and the auxiliary body 145 can be metal walls, which can correspondingly cover the main body segment 1121 and the auxiliary segment 1122.

[0256] When the first base 11 and the first fitting 14 are made using an insert injection molding process, the material of the main body section 1121 is tightly bonded to the main body part 144, and the material of the auxiliary section 1122 is tightly bonded to the auxiliary part 145.

[0257] When the first base 11 and the first fitting 14 are assembled, the main body 144 is assembled on the main body section 1121 and the auxiliary part 145 is assembled on the auxiliary section 1122.

[0258] For example, the main body 144 is arc-shaped, and the main body segment 1121 is arc-shaped. The main body 144 covers the main body segment 1121. The auxiliary part 145 is straight, and the auxiliary segment 1122 is straight, with the auxiliary part 145 covering the auxiliary segment 1122.

[0259] For example, the main body 144 is semi-circular, and the main body segment 1121 is semi-circular. The main body 144 covers the main body segment 1121. The appendix 145 is linear, and the appendix segment 1122 is linear, with the appendix 145 covering the appendix segment 1122.

[0260] For example, referring to Figure 18, the main body 144 can be configured as a shape that is narrow at the top and wide at the bottom (such as a trapezoid or dam shape) to cover the main body section 1121, which can improve the thrust resistance of the main body section 1121.

[0261] For example, the first outer wall 142 of the first fitting 14 is a smooth surface. The first outer wall 142 covers the outer surface of the first end wall 112, which can better disperse internal stress and improve structural strength.

[0262] In some embodiments, referring to FIG19, the bottom thickness D11 of the appendix 145 is greater than the top thickness D21 of the appendix 145.

[0263] The bottom of the appendage 145 is the lowest position of the appendage 145 when the slot 114a of the first base 11 faces upward. The top of the appendage 145 is the highest position of the appendage 145 when the slot 114a of the first base 11 faces upward. The thickness of the appendage 145 is the dimension of the appendage 145 in the width direction Y1 of the first base 11.

[0264] The appendix 145 is designed with a shape that is narrow at the top and wide at the bottom (such as a trapezoid or dam shape) to cover the appendix 1122, which can improve the thrust resistance of the appendix 1122.

[0265] In other embodiments, the bottom thickness of the appendix 145 is equal to the top thickness of the appendix 145. The appendix 145 may not be configured as being narrower at the top and wider at the bottom. By making the bottom thickness of the main body 144 greater than the top thickness of the main body 144, the thrust resistance of the first end wall 112 can be improved.

[0266] In some embodiments, referring to (a) to (d) in FIG20, the outer wall 144a of the main body 144 is a continuous wall surface. This can improve the structural strength of the main body 144 and the main body segment 1121 to a certain extent, and the first fitting 14 is not easily damaged when the socket 10 and the plug 20 are forcibly fastened.

[0267] In some embodiments, referring to (a) to (d) in Figures 21 and 22, the outer wall 144a of the main body 144 is a discontinuous wall surface. That is, the outer wall of the main body 144 has holes 1441, and the material of the main body 144 can be filled into the holes 1441. When the main body 144 and the main body segment 1121 are integrally formed by insert injection molding, the materials of the main body 144 and the main body segment 1121 are tightly bonded, and the bonding effect is good.

[0268] In some embodiments, the outer wall of the appendix 145 may be continuous or discontinuous. The inner wall of the appendix 145 may be continuous or discontinuous. When the appendix 145 and the appendix segment 1122 are integrally molded as an insert, the materials of the appendix 145 and the appendix segment 1122 are tightly bonded, resulting in a good bonding effect.

[0269] In some embodiments, referring to (a) to (d) in FIG20 and (a) to (d) in FIG21, the inner wall 144b of the main body 144 and the inner wall of the accessory 145 are connected. This can improve the structural strength of the main body 144 and the accessory 145 to a certain extent, and the first fitting 14 is not easily damaged when the socket 10 and the plug 20 are forcibly fastened.

[0270] In some embodiments, referring to Figures 22(a) to (d), the inner wall 144b of the main body 144 and the inner wall of the appendage 145 are spaced apart. That is, a hole 1442 is formed between the inner wall of the main body 144 and the inner wall of the appendage 145. The material of the first end wall 112 can be filled into the hole 1442. When the first fitting 14 and the first end wall 112 are integrally formed by insert injection molding, the materials of the first fitting 14 and the first end wall 112 are tightly bonded, resulting in a good bonding effect.

[0271] In some embodiments, referring to Figures 13 and 18, the first fitting 14 has a first outer wall 142. The first outer wall 142 of the first fitting 14 can have various predetermined shapes when cut along a vertical plane (i.e., the plane containing X1 and Z1) in the width direction of the first base 11. These include an inclined line extending from the bottom towards the central island 113, an inclined line extending from the bottom away from the central island 113, or an outwardly convex arc line away from the central island 113. Making the bottom of the first fitting 14 thicker can improve the thrust resistance of the first end wall 112 and the first fitting 14.

[0272] The following is a strength simulation experiment of the fittings, comparing the related technical socket fitting 2e (hereinafter referred to as the comparative fitting) and the first fitting 14 of this embodiment as shown in Figure 1. In this embodiment, the first fitting 14 of the electrical connector 100 covers the first end wall 112. The first fitting 14 is designed to be narrower at the top and wider at the bottom, roughly trapezoidal or dam-shaped. The comparative fitting and the first fitting 14 of this embodiment use the same material and have the same length and width dimensions. The first set of simulation experiments simulates the process where the socket and plug just make contact but are not fully engaged. The socket fitting 2e / first fitting 14 of the socket will be subjected to the tilting thrust of the plug. As the engagement amount of the socket and plug increases, the tilting thrust of the socket fitting 2e / first fitting 14 of the socket gradually increases. When the engagement amount is 0.20 mm, the tilting thrust of the comparative fitting is 32.94 Newtons (N), and the tilting thrust of the first fitting 14 of this embodiment is 62.95 N. Compared to the comparative fittings, the strength of the first fitting 14 in this embodiment is increased by approximately 1.9 times.

[0273] The second set of simulation experiments simulates the process before the socket and plug are fully engaged. The socket fitting 2e / first fitting 14 experiences a horizontal thrust from the plug. As the engagement depth increases, the horizontal thrust on the socket fitting 2e / first fitting 14 gradually increases. At an engagement depth of 0.028 mm, the horizontal thrust of the comparative fitting is 16.57 N, while the horizontal thrust of the first fitting 14 in this embodiment is 27.39 N. Compared to the comparative fitting, the strength of the first fitting 14 in this embodiment is increased by approximately 1.65 times.

[0274] Based on the above strength simulation experiments, it can be concluded that the first fitting 14 in this embodiment has high strength and is not easily crushed or damaged when forcibly fastened.

[0275] There are several possible implementation methods for setting the positioning part 13. For example, the positioning part 13 can be a protrusion formed on the top of the first hardware 14, or the positioning part 13 can be a boss provided on the first base 11.

[0276] In some embodiments, referring to Figures 14(a) to (d), the positioning portion 13 is a protrusion 131 formed on at least a portion of the top 14a of at least one first fitting 14. The top 14a of the first fitting 14 is the highest position of the first fitting 14 when the slot 114a of the first base 11 faces upward. The at least a portion of the top 14a of the first fitting 14 can be the entire top of the first fitting 14 or a partial top of the first fitting 14. The protrusion 131 and the first fitting 14 are made into an integral structure, such as a metal part manufactured by a drawing process, which is easy to form and has good structural strength. The positioning portion 13 can be inserted into the positioning hole 311 of the second electronic component 300, enabling rapid pre-positioning of the socket 10 and the plug 20, resulting in a smaller deviation before engagement.

[0277] For example, referring to Figures 4 and 8, two first fittings 14 each have a protrusion 131, which are arranged at intervals along the length X1 of the first base 11. The electronic component (second electronic component 300) has two corresponding positioning holes 311. During the engagement of the socket 10 and the plug 20, the two protrusions 131 are inserted into the two positioning holes 311 one-to-one. This ensures that the deviation between the socket 10 and the plug 20 before engagement is less than or equal to 0.20 mm, enabling the socket 10 and the plug 20 to engage quickly and accurately, and preventing damage to the socket 10 and the plug 20 caused by tilting during engagement.

[0278] For example, one of the first fittings 14 has a protrusion 131, and the electronic component (second electronic component 300) has a corresponding positioning hole 311. During the engagement of the socket 10 and the plug 20, the protrusion 131 is inserted into the positioning hole 311 to achieve pre-positioning of the socket 10 and the plug 20.

[0279] In some embodiments, referring to FIG13, the protrusion 131 is covered with a filling material portion 131b. The filling material portion 131b covering the inside of the protrusion 131 may be the material of the first base 11. The filling material portion 131b is connected to the top 10c of the first end wall 112. By insert injection molding, the protrusion 131 and the integral metal part of the first fitting 14 are combined with the material of the first base 11 to obtain the socket 10.

[0280] In some embodiments, referring to Figures 9, 13, and 14, the first fitting 14 includes a first top wall 141, a first outer wall 142, and a first inner wall 143. The first top wall 141 connects the first outer wall 142 and the first inner wall 143. The first outer wall 142 covers the outer surface 112c of the first end wall 112 and the outer surface 131b1 of the filling material portion 131b. The first inner wall 143 covers the inner surface 112d of the first end wall 112 and the inner surface 131b2 of the filling material portion 131b. The first top wall 141 at least covers the top surface 131b3 of the filling material portion 131b. The outer surface 112c and the inner surface 112d of the first end wall 112 are arranged back-to-back, and the inner surface 112d of the first end wall 112 is located near the central island portion 113. The outer side 131b1 and inner side 131b2 of the filling material section 131b are arranged back to back, and the inner side of the filling material section 131b is arranged close to the central island section 113.

[0281] The first fitting 14 adopts a full-coverage method, covering the outer surface 112c and inner surface 112d of the first end wall 112, and also covering the outer surface 131b1, top surface 131b3, and inner surface 131b2 of the filling material portion 131b. This can improve the structural strength of the first end wall 112 and reduce contact wear between the first end wall 112 and the second end wall 212. When the positioning portion 13 is a protrusion 131 formed on a partial top 14a of the first fitting 14, the first fitting 14 can also cover the top surface of the first end wall 112 in the area where the protrusion 131 is not provided.

[0282] In some embodiments, the first fitting 14 includes a first top wall 141 and a first outer wall 142, which are connected. The first outer wall 142 covers the outer surface 112c of the first end wall 112 and the outer surface 131b1 of the filling material portion 131b, while the first top wall 141 covers at least the top surface 131b3 of the filling material portion 131b. The first fitting 14 is partially covered, without a first inner wall 143, exposing the inner surface 112d of the first end wall 112. This improves the structural strength of the first end wall 112 and reduces the risk of damage to the first fitting 14 and the first end wall 112 when the socket 10 and plug 20 are forcibly fastened.

[0283] In some embodiments, the first fitting 14 includes a first top wall 141 and a first inner wall 143, which are connected. The first inner wall 143 covers the inner surface 112d of the first end wall 112 and the inner surface 131b2 of the filling material portion 131b, and the first top wall 141 covers at least the top surface 131b3 of the filling material portion 131b. The first fitting 14 does not have a first outer wall 142, and the outer surface 112c of the first end wall 112 is exposed. This can improve the structural strength of the first end wall 112, reduce damage to the first fitting 14 and the first end wall 112 when the socket 10 and the plug 20 are forcibly fastened, and reduce contact wear between the first end wall 112 and the second end wall 212.

[0284] In some other embodiments, the protrusion 131 may not have a filling material portion 131b inside. The protrusion 131 is part of the first fitting 14.

[0285] In some embodiments, referring to Figures 8, 13, and 14, the inner surface of the protrusion 131 has a first guide surface 131a; the first guide surface 131a is used to mate with the second end wall 212 of the plug 20. As shown in Figure 8(a), the second end wall 212 is separated from the first guide surface 131a of the protrusion 131. As shown in Figure 8(b), the second end wall 212 and the first guide surface 131a push against each other to guide the second end wall 212, as shown in Figure 8(c), until the second end wall 212 and the opening 114a of the annular groove 114 are aligned in preparation for insertion. As shown in Figure 8(d), the second end wall 212 is fully engaged in the annular groove 114, and the second end wall 212 and the first end wall 112 push against each other.

[0286] Compared to the relatively short guide distance B0 of 0.20 mm for the electrical connector fittings shown in Figure 1 of related technologies, as shown in Figure 13, the guide distance B1 of the first guide surface 131a in this embodiment is longer. During the insertion process of the socket 10 and the plug 20, the first guide surface 131a plays a better guiding role for the second end wall 212, enabling the socket 10 and the plug 20 to align quickly and smoothly, thereby achieving accurate connector engagement. The guide distance B1 of the first guide surface 131a is the dimension of the first guide surface 131a in the insertion direction of the socket 10 and the plug 20 (i.e., the height direction Z1 of the first base 11). When the socket 10 and the plug 20 are inserted, the height direction Z1 of the first base 11 and the height direction Z2 of the second base 21 can be parallel. The first guide surface 131a can be set as an inclined surface or an arc-shaped surface.

[0287] For example, the inner surface of the protrusion 131 has a first guide surface 131a. The guide distance B1 of the first guide surface 131a is relatively long, reaching more than 0.3 mm. The first guide surface 131a plays a good guiding role for the second end wall 212. The guide distance B1 of the first guide surface 131a can be from 0.3 mm to 1 mm, such as 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc., and can be set as needed.

[0288] For example, referring to Figure 14, the upper part of the first inner wall 143 of the first fitting 14 can be an inclined first guide surface 131a, which guides the second end wall 212, allowing the socket 10 and plug 20 to align quickly and accurately. The lower part of the first inner wall 143 of the first fitting 14 can be arranged vertically, that is, parallel to the height direction Z1 of the first base 11, so that the second end wall 212 and the first end wall 112 can push against each other, and the socket 10 and plug 20 are stably connected.

[0289] In some embodiments, referring to Figures 9(a) to (c), 10, and 11, in the socket 10, the first terminal group 12 includes multiple rows of first terminals 12a, each row of first terminals 12a including multiple first inner terminals 121 and multiple first outer terminals 122. The contact portions 121b of the multiple first inner terminals 121 are flush, and the contact portions 122b of the multiple first outer terminals 122 are flush. The contact portions 121b of the first inner terminals 121 and the contact portions 122b of the first outer terminals 122 are spaced apart along the width direction Y1 of the first base 11. The contact portions 121b of the first inner terminals 121 and the contact portions 122b of the first outer terminals 122 may have generally U-shaped slots. In the same row of first terminals 12a, the first inner terminals 121 and the first outer terminals 122 are arranged alternately along the length direction X1 of the first base 11. Referring to Figure 11, looking directly at the slot 114a of the first base 11, the contact portion 121b of the first inner terminal 121 and the contact portion 122b of the first outer terminal 122 in the same row of first terminals 12a are arranged in an alternating concave-convex manner.

[0290] In some embodiments, referring to Figures 9(a) to (c), 10, and 12, in the plug 20, the second terminal group 22 includes multiple rows of second terminals 22a, each row of second terminals 22a including multiple second inner terminals 221 and multiple second outer terminals 222. The contact portions 221b of the multiple second inner terminals 221 are flush, and the contact portions 222b of the multiple second outer terminals 222 are flush. The contact portions 221b of the second inner terminals 221 and the contact portions 222b of the second outer terminals 222 are spaced apart along the width direction Y2 of the second base 21. The contact portions 221b of the second inner terminals 221 and the contact portions 222b of the second outer terminals 222 may be generally U-shaped. In the same row of second terminals 22a, along the length direction X2 of the second base 21, the second outer terminals 222 and the second inner terminals 221 are arranged alternately. Referring to Figure 12, looking directly at the slot 213a of the second base 21, the contact portion 221b of the second inner terminal 221 and the contact portion 222b of the second outer terminal 222 in the same row of second terminals 22a are arranged in an alternating concave-convex manner.

[0291] When the first base 11 and the second base 21 are plugged in, the contact portions 121b of the first inner terminal 121 and the contact portions 221b of the second inner terminal 221 abut against each other in a corresponding manner, and the contact portions 122b of the first outer terminal 122 and the contact portions 222b of the second outer terminal 222 abut against each other in a corresponding manner. The U-shaped contact portion 221b of the second inner terminal 221 is inserted into the corresponding contact portion 121b (U-shaped slot) of the first inner terminal 121. The U-shaped contact portion 222b of the second outer terminal 222 is inserted into the corresponding contact portion 122b (U-shaped slot) of the first outer terminal 122. This achieves both mechanical and electrical connection between the socket 10 and the plug 20.

[0292] The contact portions of the first terminal 12a and the second terminal 22a are arranged in an alternating concave-convex pattern. Only when the first inner terminal 121 and the second inner terminal 221 are in one-to-one contact, and the first outer terminal 122 and the second outer terminal 222 are in one-to-one contact, can the socket 10 and plug 20 achieve complete engagement and effective electrical connection. If the first inner terminal 121 and the second inner terminal 221 are misaligned (the first outer terminal 122 and the second outer terminal 222 are misaligned), the second inner terminal 221 will be blocked by the adjacent first outer terminal 122 and cannot be further inserted, and the second outer terminal 222 will be blocked by the adjacent first inner terminal 121 and cannot be further inserted. This prevents the socket 10 and plug 20 from fully engaging, thus preventing misalignment of the first terminal 12a and the second terminal 22a after engagement, which could lead to circuit malfunction or short circuit risk.

[0293] The contact portion of the first terminal 12a of the socket 10 and the contact portion of the second terminal 22a of the plug 20 are arranged in an alternating concave-convex manner. Combined with the positioning portion 13 of the socket 10 and the positioning hole 311 of the electronic component (second electronic component 300) for mating, the socket 10 and plug 20 in the miniature connector can be quickly pre-positioned and accurately engaged, reducing the damage caused when the socket 10 and plug 20 are forcibly engaged due to large engagement deviation.

[0294] In some embodiments, referring to FIG9, in the socket 10, in two adjacent rows of first terminals 12a, along the width direction Y1 of the first base 11, the first inner terminal 121 in one row of first terminals 12a and the first outer terminal 122 in the other row are arranged opposite each other. In the plug 20, in two adjacent rows of second terminals 22a, the second inner terminal 221 in one row of second terminals 22a and the second outer terminal 222 in the other row of second terminals 22a are arranged opposite each other. When the first base 11 and the second base 21 are plugged in, the contact portion 121b of the first inner terminal 121 and the contact portion 221b of the second inner terminal 221 abut against each other, and the contact portion 122b of the first outer terminal 122 and the contact portion 222b of the second outer terminal 222 abut against each other.

[0295] In some embodiments, referring to Figures 9 to 11, in the socket 10, along the width direction Y1 of the first base 11, the tail portion 121a and the contact portion 121b of the first inner terminal 121 are disposed opposite to each other, and the tail portion 122a and the contact portion 122b of the first outer terminal 122 are disposed opposite to each other. The tail portion 121a of the first inner terminal 121 and the tail portion 122a of the first outer terminal 122 are the positions where they are soldered to the first electronic component 200. The tail portion 121a of the first inner terminal 121 is located inside the first base 11 along the width direction Y1 of the first base 11, and may be located in the central island portion 113. The tail portion 122a of the first outer terminal 122 is located outside the first base 11 along the width direction Y1 of the first base 11, and may be located outside the first sidewall 111. The tail portions of the first inner terminal 121 and the first outer terminal 122 face opposite directions along the width direction Y1 of the first base 11. The first terminals 12a in the same row can be reliably soldered onto the first electronic component 200, and adjacent first terminals 12a are not prone to bridging during soldering.

[0296] In some embodiments, referring to Figures 9, 10, and 12, in the plug 20, along the width direction Y2 of the second base 21, the tail portion 221a and the contact portion 221b of the second inner terminal 221 are disposed opposite to each other. The tail portion 222a and the contact portion 222b of the second outer terminal 222 are disposed opposite to each other. The tail portions 221a of the second inner terminal 221 and the tail portions 222a of the second outer terminal 222 are the positions where they are soldered to the second electronic component 300. The tail portion 221a of the second inner terminal 221 is located inside the second base 21 along the width direction Y2 of the second base 21, and may be located on the bottom surface of the groove 213. The tail portion 222a of the second outer terminal 222 is located outside the second base 21 along the width direction Y2 of the second base 21, and may be located outside the second sidewall 211. The tail portions of the second inner terminal 221 and the second outer terminal 222 face opposite directions along the width direction Y2 of the second base 21. The second terminals 22a in the same row can be reliably soldered onto the second electronic component 300, and adjacent second terminals 22a are less likely to brittle during soldering.

[0297] Compared to the related electrical connectors shown in Figure 1, in this embodiment, the first inner terminal 121 and the first outer terminal 122 in the same row of first terminals 12a are arranged alternately, and their tails are located on the inner and outer sides of the first base 11 respectively. The distance A1 between adjacent first inner terminals 121 and first outer terminals 122 can be reduced by half, thereby reducing the length or area of ​​the socket 10. In this embodiment, the second inner terminal 221 and the second outer terminal 222 in the same row of second terminals 22a are arranged alternately, and their tails are located on the inner and outer sides of the second base 21 respectively. The distance A1 between adjacent second inner terminals 221 and second outer terminals 222 can be reduced by half, thereby reducing the length or area of ​​the plug 20. This achieves an ultra-miniature connector. The distance A1 between adjacent terminals refers to the distance between the center lines of two adjacent terminals.

[0298] For example, as shown in FIG1, the minimum spacing A0 between adjacent terminals in the related art electrical connector 100 is 0.30 mm. As shown in FIGS. 11 and 12, in this embodiment, the spacing A1 between the first inner terminal 121 and the first outer terminal 122 can be reduced to 0.15 mm. In this embodiment, the spacing A1 between the second inner terminal 221 and the second outer terminal 222 can also be reduced to 0.15 mm. With the development of soldering technology, the minimum spacing between adjacent terminals will be further reduced.

[0299] When setting up the socket 10 and plug 20, the number of rows of the first terminal 12a in the first terminal group 12 is equal to the number of rows of the second terminal 22a in the second terminal group 22, so that the two are compatible. For example, the first terminal 12a and the second terminal 22a are both two rows, or the first terminal 12a and the second terminal 22a are both three rows, and the specific number of rows is set as needed.

[0300] In some embodiments, referring to FIG. 23 and FIG. 24(a), the positioning part 13 is a protrusion 131 formed on a partial top 14a of the first fitting 14. The second electronic component 300 is provided with a positioning hole 311. The positioning hole 311 and the positioning part 13 are similar in size in the length direction X1 of the first base 11, and similar in size in the width direction Y1 of the first base 11. During the insertion of the positioning part 13 into the positioning hole 311, the positioning part 13 can contact the inner wall 311a of the positioning hole 311, thereby achieving positioning in the length direction X1 of the first base 11. The positioning part 13 can contact the inner wall 311b of the positioning hole 311, thereby achieving positioning in the width direction Y1 of the first base 11. Positioning guidance in two directions can be achieved.

[0301] In some embodiments, referring to FIG. 23 and FIG. 24(b), the positioning portion 13 is a protrusion 131 formed on a partial top 14a of the first fitting 14. The second electronic component 300 is provided with a positioning hole 311. The positioning hole 311 and the positioning portion 13 are approximately the same size in the longitudinal direction X1 of the first base 11. In the width direction Y1 of the first base 11, the size of the positioning hole 311 is significantly larger than the size of the positioning portion 13. During the insertion of the positioning portion 13 into the positioning hole 311, the positioning portion 13 can contact the inner wall 311a of the positioning hole 311, thereby achieving positioning in the longitudinal direction X1 of the first base 11. Positioning guidance in a single direction can be achieved.

[0302] In some embodiments, referring to FIG25, the first base 11 includes a pair of first sidewalls 111 extending along the length direction X1 of the first base 11, and the pair of first sidewalls 111 being spaced apart along the width direction Y1 of the first base 11. The first base 11 also includes a pair of outer sidewalls 116 spaced apart along the width direction Y1 of the first base 11, and the pair of first sidewalls 111 being located between the pair of outer sidewalls 116.

[0303] The paired first end walls 112 and paired outer walls 116 are combined to form a ring structure, which can be roughly elliptical, circular, or other ring-shaped, and this ring structure surrounds the first side wall 111. The first fitting 14 covers the first end wall 112 and also covers the outer wall 116. This can improve the structural strength of the first base 11 and reduce the possibility of damage to the socket 10 and plug 20 during engagement. This method is suitable for scenarios where space is not restricted.

[0304] In some embodiments, referring to Figures 26 to 31, the positioning part 13 is a boss 132 provided on the first base 11. The positioning part 13 can be provided at different positions on the first base 11. For example, as shown in Figures 26 and 28, the positioning part 13 can be provided on the first end wall 112 of the first base 11; as shown in Figures 30 and 31, the positioning part 13 can be provided on the central island portion 113 of the first base 11; the positioning part 13 can be provided on the first side wall 111 of the first base 11. The electronic component (second electronic component 300) is provided with positioning holes 311 at corresponding positions. By the insertion and cooperation of the boss 132 of the first base 11 and the positioning holes 311, the pre-positioning of the socket 10 and the plug 20 can be realized.

[0305] As shown in Figures 26, 28 and 30, the positioning part 13 can be assembled into the first base 11, or, as shown in Figure 31, the positioning part 13 can also be integrally injection molded into the first base 11.

[0306] For example, referring to FIG30, the positioning part 13 may be formed at the top position of the island part 113. For instance, a boss 132 may be provided at both ends of the island part 113 along the length direction X1 of the first base 11, and positioning holes 311 may be provided at corresponding positions of the second base 21 of the plug 20 and the electronic component (second electronic component 300). During the engagement of the socket 10 and the plug 20, the boss 132 is inserted into the positioning hole 311 to achieve the pre-positioning of the socket 10 and the plug 20.

[0307] In some embodiments, referring to Figures 26 to 30, the boss 132 is a columnar body extending along the height direction Z1 of the first base 11. The columnar boss 132 can better engage with the positioning hole 311 on the electronic component (second electronic component 300) to achieve pre-positioning of the connector.

[0308] For example, referring to Figures 26 and 27, the boss 132 is connected to the first base 11 and passes through the first fitting 14, making it easy to manufacture and assemble. During the engagement of the socket 10 and the plug 20, the boss 132 is inserted into the positioning hole 311 to achieve the pre-positioning of the socket 10 and the plug 20.

[0309] For example, the first base 11 has two columnar protrusions 132, which are correspondingly inserted into the first fitting 14. Two protrusions 131 are spaced apart along the length X1 of the first base 11, and the electronic component (second electronic component 300) has two corresponding positioning holes 311. During the engagement of the socket 10 and plug 20, the two protrusions 131 are inserted into the two positioning holes 311. This ensures that the deviation between the socket 10 and plug 20 before engagement is less than or equal to 0.20 mm, enabling quick and accurate engagement of the socket 10 and plug 20.

[0310] In some embodiments, referring to Figures 28 and 29, the insertion end edge of the positioning part 13, which is inserted into the positioning hole 311, has a chamfer 133. During the process of inserting the positioning part 13 into the positioning hole 311, the chamfer 133 of the positioning part 13 acts as a guide, allowing the plug 20 to smoothly enter the socket 10. Then, through the cooperation of the first end wall 112 and the second end wall 212, segmented guidance is achieved, so that the plug 20 and the socket 10 can be quickly fastened together.

[0311] In some embodiments, referring to Figures 28 and 29, the wall surface of the positioning hole 311 is chamfered 312, and the inner diameter of the positioning hole 311 gradually decreases in the direction in which the positioning part 13 is inserted into the positioning hole 311. During the process of inserting the positioning part 13 into the positioning hole 311, the wall surface of the positioning hole 311 guides the positioning part 13, allowing the plug 20 to smoothly enter the socket 10. Then, through the cooperation of the first end wall 112 and the second end wall 212, segmented guidance is achieved, so that the plug 20 and the socket 10 can be quickly fastened together.

[0312] For example, the boss 132 is a columnar body extending along the height direction Z1 of the first base 11. The edge of the insertion end of the positioning part 13 inserted into the positioning hole 311 is provided with a chamfer 133, and the wall surface of the positioning hole 311 is provided with a chamfered surface 312. When the columnar boss 132 is inserted into the positioning hole 311, the socket 10 and the plug 20 can be easily and quickly and accurately engaged.

[0313] In some embodiments, referring to Figures 32 and 33, the first reinforcing part 10a is a first end wall 112, that is, no first fitting 14 is provided on the outside of the first end wall 112. The first end wall 112 is made of a high-strength material (such as ceramic), so there is no need to provide the first fitting 14. The positioning part 13 can be a boss 132 provided on at least part of the top of the first end wall 112. The inner side of the boss 132 has a second guide surface 132a; the second guide surface 132a is used to mate with the second end wall 212 of the plug 20.

[0314] Compared to the shorter guide distance B0 of the related electrical connector fittings shown in Figure 1, the guide distance B2 of the second guide surface 132a in this embodiment is longer. During the insertion process of the socket 10 and the plug 20, the second guide surface 132a plays a better guiding role for the second end wall 212, enabling the socket 10 and the plug 20 to align quickly and smoothly, thereby achieving accurate connector engagement. The guide distance B2 of the second guide surface 132a is the dimension of the second guide surface 132a in the insertion direction of the socket 10 and the plug 20 (the height direction Z1 of the first base 11). The second guide surface 132a can be set as an inclined surface or an arc-shaped surface.

[0315] For example, each of the two first end walls 112 is formed with a boss 132, which can make the deviation between the socket 10 and the plug 20 less than or equal to 0.20 mm before they are engaged, so as to achieve quick and accurate engagement of the socket 10 and the plug 20 and prevent damage to the socket 10 and the plug 20 caused by tilting during engagement.

[0316] Referring to Figures 4 to 10, this application embodiment provides a plug component 300a, including a second electronic component 300 and a plug 20, the plug 20 being connected to the second electronic component 300; the plug 20 includes a second base 21 and a second terminal group 22, the second terminal group 22 being disposed on the second base 21; the plug 20 is used to engage with a socket 10, the socket 10 having a positioning part 13; the second electronic component 300 has a positioning hole 311 for engaging with the positioning part 13.

[0317] The plug component 300a provided in this application embodiment has a socket 10 with a positioning part 13 and a second electronic component 300 connected to the plug 20 with a positioning hole 311. As shown in Figures 8(a) and (b), before the socket 10 and the plug 20 are fastened together, the positioning part 13 of the socket 10 is inserted into the positioning hole 311 of the electronic component (second electronic component 300) to achieve rapid pre-positioning of the socket 10 and the plug 20, so that the deviation before fastening is small, as shown in Figures 8(c) and (d), thereby enabling the socket 10 and the plug 20 to be accurately fastened together and reducing the damage caused by forcibly fastening the socket 10 and the plug 20.

[0318] It is understandable that the aforementioned plug embodiments 20 can all be applied to the plug component 300a of this embodiment, and will not be described again here.

[0319] In some embodiments, referring to Figures 4 and 16, the plug 20 has a pair of second reinforcing portions 20a, which are distributed at opposite ends along the longitudinal direction Y2 of the second base 21. The second reinforcing portions 20a enhance the structural strength of the plug 20's end position, reducing damage to the plug 20's end during the insertion process of the socket 10 and plug 20. During the insertion process of the socket 10 and plug 20, the second reinforcing portions 20a provide a guiding effect, ensuring smooth alignment and insertion of the socket 10 and plug 20.

[0320] In some embodiments, referring to Figures 5, 9, 10, and 13, the second reinforcing portion 20a includes a second end wall 212 and a second fitting 23, the second fitting 23 covering at least a portion of the surface of the second end wall 212. The second fitting 23 can improve the structural strength at the location of the second end wall 212 and reduce the possibility of contact wear and crush damage to the second end wall 212.

[0321] For example, the second fitting 23 can be made of metal (such as copper), can be manufactured by drawing process, is easy to form, and has good structural strength.

[0322] For example, the second base 21 can be injection molded with the second fitting 23 as an insert, so that the material of the second base 21 and the second fitting 23 and the second terminal group 22 are tightly bonded together.

[0323] For example, the second fitting 23 may be assembled onto the second base 21 by insert or other means.

[0324] In some embodiments, the second reinforcing part 20a is a second end wall 212, that is, no second fitting 23 is provided outside the second end wall 212. The second end wall 212 is made of a high-strength material (such as ceramic), so there is no need to provide a second fitting 23.

[0325] In some embodiments, referring to Figures 13 and 18, in the length direction of the second base 21, the bottom dimension D3 of the second reinforcing part 20a is greater than the top dimension D4 of the second reinforcing part 20a.

[0326] The bottom of the second reinforcing part 20a is the lowest position of the second reinforcing part 20a when the slot 213a of the second base 21 faces upwards. The bottom dimension D3 of the second reinforcing part 20a refers to the bottom dimension of the second reinforcing part 20a along the length direction X2 of the second base 21. The top of the second reinforcing part 20a is the highest position of the second reinforcing part 20a when the slot 213a of the second base 21 faces upwards. The top dimension D4 of the second reinforcing part 20a refers to the top dimension of the second reinforcing part 20a along the length direction X2 of the second base 21.

[0327] When the slot 213a of the second base 21 faces upward, the second reinforcing part 20a is configured to be narrower at the top and wider at the bottom, such as a trapezoid or dam shape. The second reinforcing part 20a is configured with a thicker bottom, which can better improve the thrust resistance of the second reinforcing part 20a, reduce the possibility of damage to the second reinforcing part 20a when the socket 10 and plug 20 are forcibly fastened due to a large fastening deviation, and improve reliability.

[0328] For example, the second reinforcing part 20a includes a second end wall 212 and a second fitting 23, with the second fitting 23 covering the second end wall 212. When the slot 213a of the second base 21 faces upward, the second fitting 23 is configured to be narrower at the top and wider at the bottom, covering the surface of the second end wall 212. This improves the thrust resistance of the second fitting 23 and reduces the risk of damage to the second fitting 23 and the second end wall 212 when the socket 10 and plug 20 are forcibly fastened.

[0329] For example, the second reinforcing part 20a is the second end wall 212. When the slot 213a of the second base 21 faces upward, the second end wall 212 is set to a shape that is narrow at the top and wide at the bottom, which can improve the thrust resistance of the second end wall 212 and reduce the damage to the second end wall 212 when the socket 10 and the plug 20 are forcibly fastened.

[0330] Referring to Figure 34, an embodiment of this application provides a device 2000, including the aforementioned socket 10, or the aforementioned plug 20, or the aforementioned plug component 300a, or the aforementioned electrical connector 100, or the aforementioned electronic component 1000.

[0331] Among them, device 2000 can be a mobile phone, tablet computer, super mobile personal computer, e-book reader, netbook, personal digital assistant, wearable device, augmented reality (AR) device, virtual reality (VR) device, television, drone, action camera, dashcam, in-vehicle equipment, robot, etc.

[0332] For example, referring to Figure 34, device 2000 is a folding machine, which includes a first housing 2001, a second housing 2002, and a pivot assembly 2003. The first housing 2001 and the second housing 2002 are connected by the pivot assembly 2003. Both the first housing 2001 and the second housing 2002 can rotate relative to the pivot assembly 2003, realizing the switching between the flattened state and the closed state of the folding machine. The first housing 2001 and the second housing 2002 can be a middle frame.

[0333] A first circuit board 2004 is housed within a first housing 2001, and a second circuit board 2005 is housed within a second housing 2002. Both circuit boards 2004 and 2005 are rigid circuit boards. The first circuit board 2004 and the second circuit board 2005 are connected by a through-shaft circuit board 2006, which is a flexible circuit board and is inserted into the rotating shaft assembly 2003. One end of the through-shaft circuit board 2006 is connected to the first circuit board 2004 via an electrical connector 100a. The other end of the through-shaft circuit board 2006 is connected to the second circuit board 2005 via an electrical connector 100b. This ensures that the first circuit board 2004 and the second circuit board 2005 are electrically connected via the through-shaft circuit board 2006.

[0334] The first housing 2001 contains a battery 2007, which has a first flexible plate 2007a. The first flexible plate 2007a and the first circuit board 2004 are connected by an electrical connector 100c.

[0335] The first housing 2001 is provided with a camera module 2008, which has a second flexible plate 2008a. The second flexible plate 2008a and the first circuit board 2004 are connected by an electrical connector 100d.
