Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an electrical connector, a circuit board assembly and an electronic device. Background Art

[0002] With the continuous development of electronic devices, miniaturization has gradually become a significant competitive advantage of electronic devices. At present, the connection between the screen, various sensors, etc. and the mainboard in common electronic devices mostly adopts a flexible printed circuit (FPC) transfer solution, and the FPC is electrically connected to the mainboard through a board to board connector (BTB) or a zero insertion force connector (ZIF). However, both the BTB connector and the ZIF connector require a press-fit structure to fix the FPC, resulting in a larger internal space of the electronic device, which is not conducive to the miniaturization of the electronic device. Summary of the invention

[0003] The present application provides an electrical connector, a circuit board assembly and an electronic device.

[0004] In a first aspect, an embodiment of the present application provides an electrical connector. The electrical connector is used for electrical connection between a circuit board and a signal transmission structure. The electrical connector includes an insulating shell and a terminal. The terminal is fixedly connected to the insulating shell. A plug-in space is provided inside the insulating shell. An opening is provided on the bottom surface of the insulating shell, and the opening connects the plug-in space and the outside of the insulating shell. The bottom surface of the insulating shell faces the circuit board. At least a portion of the first electrical connection end of the terminal is located in the plug-in space, which is used to electrically connect the signal transmission structure. The second electrical connection end of the terminal extends through the bottom surface of the insulating shell, which is used to electrically connect the circuit board. When the electrical connector is used to electrically connect the signal transmission structure, the signal transmission structure enters the plug-in space through the opening and connects the first electrical connection end of the terminal.

[0005] It can be understood that the electrical connector of the present application realizes electrical connection between the first electrical connection end and the second electrical connection end of the terminal on one side of the bottom surface of the electrical connector, and the signal transmission structure and the circuit board. In this way, the signal transmission structure can be fixed by utilizing the cooperation of the circuit board and the surrounding structure. Compared with the ZIF connector or the BTB connector, the electrical connector provided by the present application does not need to set up an additional pressing structure for fixing the signal transmission structure, which can effectively reduce the volume of the electrical connector and reduce the cost.

[0006] In a possible implementation, the terminal includes a first terminal and a second terminal, and a portion of a first electrical connection end of the first terminal and a portion of a third electrical connection end of the second terminal are located on both sides of the plug-in space. When the first plug-in end of the signal transmission structure is plugged into the plug-in space, the first electrical connection end of the first terminal and the third electrical connection end of the second terminal are respectively connected to both sides of the signal transmission structure.

[0007] It can be understood that the terminal includes a technical solution of a first terminal and a second terminal, and the first plug-in end of the signal transmission structure can realize double-sided signal output. When the number of terminals remains unchanged, compared with the solution of single-sided signal output, the volume of the electrical connector can be effectively reduced, which is conducive to the miniaturization of electronic equipment. In addition, the solution of double-row terminals can be compatible with both the signal transmission structure with single-sided signal output and the signal transmission structure with double-sided signal output, and the application scenario of the electrical connector is less restricted. When the signal transmission structure has double-sided signal output, contact areas are provided on both sides of the first plug-in end, and the first electrical connection end of the first terminal and the third electrical connection end of the second terminal are respectively connected to the contact areas on both sides of the first plug-in end.

[0008] In one possible implementation, the insulating housing is further provided with a first movable space. The first movable space is connected to the plug-in space and is located on one side of the plug-in space. The first terminal is partially located in the first movable space. The first terminal is also used to abut against the first plug-in end of the signal transmission structure when the first plug-in end of the signal transmission structure is plugged into the plug-in space. The first movable space is used to provide space for the deformation of the first terminal when the first terminal abuts against the first plug-in end of the signal transmission structure. And / or

[0009] The insulating housing is also provided with a second movable space. The second movable space is connected to the plug-in space and is located on a side of the plug-in space away from the first movable space. At least part of the second terminal is located in the second movable space. The second terminal is also used to abut against the first plug-in end of the signal transmission structure when the first plug-in end of the signal transmission structure is plugged into the plug-in space, and the second movable space is used to provide space for the deformation of the second terminal when the second terminal abuts against the first plug-in end of the signal transmission structure.

[0010] It can be understood that the first movable space is used to provide space for deformation of the first electrical connection end of the first terminal when the first terminal abuts against the first plug end of the signal transmission structure. The second movable space is used to provide space for deformation of the third electrical connection end of the second terminal when the second terminal abuts against the first plug end of the signal transmission structure.

[0011] In a possible implementation, the first electrical connection end of the first terminal is located on a side of the plug-in space away from the second electrical connection end of the first terminal. And / or

[0012] The third electrical connection end of the second terminal is located at a side of the plug-in space away from the fourth electrical connection end of the second terminal.

[0013] It can be understood that, compared with the first electrical connection end of the first terminal and the second electrical connection end of the first terminal being located on the same side of the first plug-in end, the first electrical connection end of the first terminal and the second electrical connection end of the first terminal are respectively located on both sides of the first plug-in end. When the first terminal abuts against the first plug-in end of the signal transmission structure, the deformation of the first terminal can be distributed more evenly to various positions of the first terminal, the deformation force exerted on the first terminal is more uniform, the service life of the first terminal is longer, and the reliability of the electrical connection between the electrical connector and the signal transmission structure is better.

[0014] Analogously to the arrangement of the first terminal, the third electrical connection end of the second terminal may also be located on a side of the plug-in space away from the second electrical connection end of the second terminal. The second terminal may be partially located in the first active space, and partially located in the second active space arranged opposite to the first active space. In this way, the deformation force on each part of the second terminal is more uniform, the service life of the second terminal is longer, and the electrical connection reliability of the electrical connector is better.

[0015] In a possible implementation, there are multiple first terminals, which are arranged at intervals along the extension direction of the plug-in space, and there are multiple second terminals, which are arranged at intervals along the extension direction of the plug-in space. Along the extension direction of the plug-in space, the multiple first terminals and the multiple second terminals are arranged alternately.

[0016] It can be understood that the plurality of first terminals and the plurality of second terminals are arranged alternately, so that the signal transmission is more compact.

[0017] In a possible implementation, the first electrical connection end of the first terminal and the second electrical connection end of the first terminal are located on the same side of the insertion space.

[0018] and / or

[0019] The third electrical connection end of the second terminal and the fourth electrical connection end of the second terminal are located on the same side of the plug-in space.

[0020] It can be understood that the first terminal and the second terminal are respectively located on both sides of the plug-in space. When the signal transmission structure enters the plug-in space, the first terminal and the second terminal can be respectively located on both sides of the signal transmission structure.

[0021] In a possible implementation manner, the first electrical connection end of the first terminal and the third electrical connection end of the second terminal are arranged opposite to each other.

[0022] In one possible implementation, along the extension direction of the plug-in space, a projection of the first electrical connection end of the first terminal on a reference plane partially overlaps with a projection of the third electrical connection end of the second terminal on the reference plane, and the reference plane is perpendicular to the extension direction of the plug-in space.

[0023] It can be understood that along the extension direction of the plug-in space, the projection of the first electrical connection end of the first terminal on the reference plane and the projection of the third electrical connection end of the second terminal on the reference plane partially overlap, which is beneficial to reducing the volume of the electrical connector and miniaturizing the electronic device.

[0024] In a possible implementation, the first electrical connection end of the terminal is in a “V” shape, a “U” shape, an “S” shape, a wave shape, or a paper clip shape.

[0025] In a possible implementation, the insulating housing includes a positioning structure, and the positioning structure is a through hole or a groove.

[0026] It can be understood that the positioning structure can be used to assist in positioning during the installation of the circuit board assembly to improve the efficiency of the installation.

[0027] In a possible implementation, the electrical connector further includes a reinforcing piece made of metal material, the reinforcing piece is fixedly connected to the insulating housing, and the reinforcing piece is used to enhance the connection strength between the electrical connector and the circuit board.

[0028] It is understandable that the electrical connector can enhance the reliability of the connection with the circuit board by providing a reinforcement piece, thereby improving the reliability of the electrical connection between the electrical connector and the signal transmission structure.

[0029] In a second aspect, an embodiment of the present application provides a circuit board assembly. The circuit board assembly includes a circuit board and an electrical connector, wherein the electrical connector is fixedly connected to the circuit board.

[0030] It can be understood that the electrical connector realizes electrical connection with the signal transmission structure and the circuit board by connecting the first electrical connection end and the second electrical connection end of the terminal on one side of the bottom surface of the electrical connector. In this way, the signal transmission structure can be fixed by utilizing the cooperation between the circuit board and the insulating shell of the electrical connector. Therefore, compared with the ZIF connector or the BTB connector, the electrical connector provided in the present application does not need to additionally set up a pressing structure for fixing the signal transmission structure, which can effectively reduce the volume of the electrical connector and the volume of the circuit board assembly is also smaller.

[0031] In a possible implementation, the circuit board is provided with a first through hole, and the first through hole is arranged opposite to the electrical connector.

[0032] It is understandable that the first plug end of the signal transmission structure can pass through the circuit board through the first through hole and electrically connect the terminal. In this way, the signal transmission structure can be laid between the circuit board and the housing (as shown in the figure). The electrical connector is fixedly connected to the side surface of the circuit board away from the housing, and the signal transmission structure can be partially located between the circuit board and the housing. The circuit board and the housing cooperate to support the signal transmission structure, thereby achieving the fixation of the signal transmission structure.

[0033] In a third aspect, an embodiment of the present application provides an electronic device, wherein the electronic device comprises a housing and a circuit board assembly, wherein the circuit board assembly is installed in the housing.

[0034] It can be understood that the circuit board assembly is installed in the shell, the signal transmission structure can be laid between the circuit board and the shell, the electrical connector is fixedly connected to the side surface of the circuit board away from the shell, the signal transmission structure can be partially located between the circuit board and the shell, and the signal transmission structure is fixed by the circuit board and the shell cooperating to support the signal transmission structure.

[0035] In addition, compared with the solution in which the signal transmission structure is connected from the top surface or the peripheral side surface of the electrical connector, by connecting the signal transmission structure from the bottom surface of the electrical connector, the signal transmission structure can be set close to the circuit board, and the arrangement of the signal transmission structure is more compact, which is conducive to the miniaturization of electronic equipment.

[0051] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. 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. Among them, "fixed connection" means that the relative position relationship after connection remains unchanged. It should be understood that when component A is fixedly connected to component C through component B, the relative position relationship caused by the deformation of component A, component B and component C itself is allowed to change. "Rotational connection" means that they are connected to each other and can rotate relative to each other after connection. "Sliding connection" means that they are connected to each other and can slide relative to each other after connection. Among them, the two components are obtained by an integrated molding process to obtain an integrated structure, which means that in the process of forming one of the two components, the component is connected to the other component, and the two components do not need to be connected together by reprocessing (such as bonding, welding, snap connection, screw connection). In the present application, the relative arrangement of component A and component B can be that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, and projection C and projection D can at least partially overlap. The staggered arrangement of component A and component B may be such that component A is projected along the target direction to obtain projection C, component B is projected along the target direction to obtain projection D, and projection C and projection D have no overlapping portion at all.

[0052] The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "side", "top", "bottom", etc., are only references to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0053] The term "plurality" means at least two. The term "above" includes the number itself. The term "and / or" is a description of an association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. Terms such as "first" and "second" are used for descriptive purposes only and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0056] Figure 2 yes Figure 1 FIG. 1 is a cross-sectional view of an embodiment of an electronic device 1000 taken at AA.

[0057] like Figure 1 and Figure 2 As shown, the electronic device 1000 may include a housing 100, an electronic device 200, a circuit board assembly 300, and a signal transmission structure 400. The housing 100 encloses the internal space of the electronic device 1000. The circuit board assembly 300 and the signal transmission structure 400 may be installed in the internal space of the electronic device 1000, that is, in the housing 100.

[0058] The housing 100 may be made of metal, glass, plastic, or ceramic.

[0059] The electronic device 200 may include, but is not limited to, a wireless charging coil, a battery, a sensor, a processor, an internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, an earphone interface, a sensor module, a button, a motor or an indicator, and other devices that need to be electrically connected to the circuit board assembly 300. The electronic device 200 may be embedded in the housing 100, or may be exposed from the housing 100, or may be installed in the internal space of the electronic device 1000. Different electronic devices 200 may be positioned according to actual needs. For example, when the electronic device 1000 is a smart bracelet, the wireless charging coil of the smart bracelet may be embedded in the housing 100, and electronic devices such as a communication module (not shown) may be installed in the internal space of the electronic device 1000.

[0060] In some embodiments, when the electronic device 1000 has a display function, the electronic device 200 may further include a screen 500. The screen 500 is mounted on the housing 100, and the screen 500 and the housing 100 may enclose the internal space of the electronic device 1000. The screen 500 may be used to display images, videos, and the like. In some embodiments, the screen 500 may also have a touch sensing function, and the touch sensing function of the screen 500 is used to sense the user's touch action to achieve human-computer interaction. Exemplarily, the screen 500 may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, a flexible light-emitting diode (FLED) display, a Mini-LED display, a Micro-LED display, a Micro-OLED display, a quantum dot light emitting diode (QLED) display, and the like.

[0061] Figure 3a yes Figure 2 FIG. 1 is a schematic diagram of a partial structural assembly of an electrical connector 330, a signal transmission structure 400, and a circuit board 310 according to an embodiment of the present invention. Figure 3b yes Figure 3a An exploded schematic diagram of an embodiment of the structure shown in FIG.

[0062] like Figure 2 , Figure 3a as well as Figure 3b As shown, the circuit board assembly 300 may include a circuit board 310, an electronic component 320 and an electrical connector 330. The electronic component 320 and the electrical connector 330 are both fixedly connected to the circuit board 310. The electronic component 320 and the electrical connector 330 are arranged at intervals. The electrical connector 330 can be electrically connected to the electronic component 320 through the circuit board 310. Exemplarily, the electronic component 320 can be an active device such as a chip, or a passive device such as a capacitor, an inductor, and a resistor. It is understandable that those skilled in the art can select the type of electronic component 320 and its connection method on the circuit board 310, so that the circuit board assembly 300 with specific functions, such as the mainboard of the electronic device 1000, can be selected. The electrical connector 330 is used to transfer the signal of the signal transmission structure 400 to the circuit board 310. The specific structure of the electrical connector 330 will be specifically introduced below through the accompanying drawings, and will not be repeated here.

[0063] The signal transmission structure 400 is used to transmit the signal of the electronic device 200 to the circuit board assembly 300, or to transmit the signal of the circuit board assembly 300 to the electronic device 200. In this way, the signal of the electronic device 200 can pass through the signal transmission structure 400, the electrical connector 330 and the circuit board 310, and finally reach the electronic component 320 on the circuit board 310. The electrical signal on the electronic component 320 can pass through the circuit board 310, the electrical connector 330, the signal transmission structure 400 in sequence, and finally reach the electronic device 200. Exemplarily, the signal transmission structure 400 may include a first plug end 410, a transmission section 420 and a second plug end 430. The transmission section 420 is connected between the first plug end 410 and the second plug end 430. The first plug end 410 is used to electrically connect the electrical connector 330. The second plug end 430 is used to electrically connect the electronic device 200.

[0064] The signal transmission structure 400 may be a flexible cable structure such as FPC, FFC, etc., or a rigid structure such as an injection molded gold finger tongue core or a PCB board. The first plug end 410 may have a contact area 411, which may be an exposed area of ​​a metal wire inside the signal transmission structure 400, for achieving electrical connection with the electronic device 200 or the electrical connector 330. In some embodiments, the second plug end 430 may also have a contact area (not shown).

[0065] The number of signal transmission structures 400 included in the electronic device 1000 may be one or more. The number of electrical connectors 330 included in a circuit board assembly 300 may be one or more. Exemplarily, the number of electrical connectors 330 may be equal to the number of signal transmission structures 400. Multiple signal transmission structures 400 and multiple electrical connectors 330 are connected in a one-to-one correspondence. When the number of signal transmission structures 400 is multiple, the multiple signal transmission structures 400 can be used for signal transmission between different electronic devices 200 and circuit board assemblies 300. In addition, the number of circuit board assemblies 300 included in the electronic device 1000 may be one or more. Electrical connectors 330 may be provided on multiple circuit board assemblies 300. Multiple signal transmission structures 400 can be connected to different circuit board assemblies 300, respectively.

[0066] For example, Figure 2 , two signal transmission structures 400 and two electrical connectors 330 are illustrated. The first plug end 410 of the first signal transmission structure 400 is connected to the first electrical connector 330, and the second plug end 430 is connected to the screen 500. The first plug end 410 of the second signal transmission structure 400 is connected to the second electrical connector 330, and the second plug end 430 is connected to the wireless charging coil in the housing 100.

[0067] The circuit board 310 can be fixedly connected to the inner surface of the housing 100 of the electronic device 1000, and the inner surface of the housing 100 faces the internal space of the electronic device 1000. Exemplarily, the circuit board 310 can be fixedly connected to the housing 100 by means of gluing, snaps, screws, etc. In other embodiments, the circuit board 310 can also be fixedly connected to other structural parts inside the electronic device 1000.

[0068] Figure 4a yes Figure 3b An exploded view of one embodiment of an electrical connector 330 is shown in FIG.

[0069] like Figure 3b and Figure 4a As shown, the electrical connector 330 includes an insulating housing 331, a terminal 332 and a reinforcing member 333. The insulating housing 331 includes a top surface 3311, a bottom surface 3312 and a peripheral side surface 3313. The top surface 3311 and the bottom surface 3312 are arranged opposite to each other, and the peripheral side surface 3313 is connected between the top surface 3311 and the bottom surface 3312. The bottom surface 3312 faces the circuit board 310. The insulating housing 331 is made of an insulating material. Exemplarily, the material of the insulating housing 331 can be plastic, which is formed by an injection molding process.

[0070] Figure 4b for Figure 4a FIG. 3 is a schematic structural diagram of the insulating housing 331 at another angle.

[0071] like Figure 4b As shown, the insulating housing 331 may include a housing body 3318 and a baffle. The housing body 3318 is provided with a receiving groove 3319, and the opening of the receiving groove 3319 is located at the bottom surface of the housing body 3318. It can be understood that the bottom surface of the housing body 3318 is a part of the bottom surface 3312 of the insulating housing, or the bottom surface of the housing body 3318 is the bottom surface 3312 of the insulating housing 331, and the opening of the receiving groove 3319 is located at the bottom surface 3312 of the insulating housing 331. When the electrical connector 330 is fixed to the circuit board 310, the opening of the receiving groove 3319 faces the circuit board 310. The baffle is fixedly connected to the bottom wall 3363 and the side wall of the receiving groove 3319.

[0072] Exemplarily, the side wall of the receiving groove 3319 includes a first side wall 3364 and a second side wall 3365 that are arranged opposite to each other. The baffle includes a first baffle 3361 and a second baffle 3362 that are arranged opposite to each other and spaced apart. The first baffle 3361 is fixedly connected to the bottom surface of the receiving groove 3319 and the first side wall 3364. The second baffle 3362 is fixedly connected to the bottom wall 3363 and the second side wall 3365 of the receiving groove 3319. The first baffle 3361 has a first side surface 3366 facing the second baffle 3362, and the second baffle 3362 has a second side surface 3367 facing the first baffle 3361. The first side surface 3366, the second side surface 3367 and the bottom wall 3363 of the receiving groove 3319 enclose the plug-in space 3314. The bottom surface 3312 of the insulating housing 331 is provided with an opening 3315, and the opening 3315 is connected to the plug-in space 3314.

[0073] The number of the first baffles 3361 and the number of the second baffles 3362 are both multiple, and the number of the first baffles 3361 is equal to the number of the second baffles 3362. The multiple first baffles 3361 are arranged at intervals along the first direction, and the multiple second baffles 3362 are also arranged at intervals along the first direction. The multiple first baffles 3361 and the multiple second baffles 3362 are arranged relative to each other in a one-to-one correspondence. Exemplarily, Figure 4b The insulating shell 331 shown in FIG. 1 has six first baffles 3361 and six second baffles 3362 .

[0074] Two adjacent first baffles 3361 and the bottom wall 3363 and the first side wall 3364 of the receiving groove 3319 enclose a first activity space 3316. The first activity space 3316 is connected to the plug-in space 3314 and is located on one side of the plug-in space 3314. Two adjacent second baffles 3362 and the bottom wall 3363 and the second side wall 3365 of the receiving groove 3319 enclose a second activity space 3317. The second activity space 3317 is connected to the plug-in space 3314 and is located on one side of the plug-in space 3314 away from the first activity space 3316. The first activity space 3316 and the second activity space 3317 are located on both sides of the plug-in space 3314. It can be understood that the first baffle 3361 and the second baffle 3362 are used to separate the receiving groove 3319 into the plug-in space 3314, the first activity space 3316 and the second activity space 3317.

[0075] The number of the first activity space 3316 can be one or more. The number of the second activity space 3317 can be one or more. Figure 4b The insulating shell 331 shown in FIG. 3 has five first activity spaces 3316 and five second activity spaces.

[0076] In some embodiments, the housing body 3318 and the baffle plate may be integrally formed structural members. For example, the insulating housing 331 may be an integral structural member formed by an injection molding process.

[0077] Figure 4c yes Figure 3a FIG. 1 is a schematic diagram of the electrical connector 330 at another angle.

[0078] like Figure 3a and Figure 4c As shown, the terminal 332 is used to electrically connect the signal transmission structure 400 and the circuit board 310. The terminal 332 can be used to transmit the signal transmission structure 400 to the circuit board 310, or to transmit the signal of the circuit board 310 to the signal transmission structure 400. The terminal 332 is fixedly connected to the insulating shell 331. It can be understood that the terminal 332 can be fixedly connected to the insulating shell 331 by means of snaps, gluing, etc., and the terminal 332 can also be embedded in the insulating shell 331. For example, the terminal 332 and the insulating shell 331 can also be formed into an integral structural part by an insert molding process. The insert molding process refers to a molding method in which a pre-prepared insert is loaded into a mold and then a molten material is injected. The molten material is bonded and solidified with the insert to form an integrated product.

[0079] Exemplarily, the terminal 332 may have a first electrical connection end electrically connected to the signal transmission structure 400 and a second electrical connection end electrically connected to the circuit board 310 .

[0080] In some embodiments, the plug-in space 3314 of the insulating housing 331 can be used to accommodate the first plug-in end 410 of the signal transmission structure 400. It is understandable that the plug-in space 3314 can limit the first plug-in end 410 of the signal transmission structure 400, so that the signal transmission structure 400 is not easy to shake. At least part of the first electrical connection end of the terminal 332 is located in the plug-in space 3314, which is used to electrically connect the first plug-in end 410 of the signal transmission structure 400.

[0081] Exemplarily, the opening 3315 is located at the bottom surface 3312 of the insulating shell 331. The opening 3315 connects the plug-in space 3314 and the external space of the insulating shell 331. When the electrical connector 330 is electrically connected to the signal transmission structure 400, the first plug-in end 410 of the signal transmission structure 400 can enter the plug-in space 3314 through the opening 3315, and the first electrical connection end of the connection terminal 332, and the first electrical connection end of the electrical connection terminal 332. It should be noted that when the electrical connector 330 is installed in the internal space of the electronic device, the external space of the insulating shell 331 may refer to the internal space of the electronic device. When the electrical connector 330 is exposed to the electronic device, the outside world may be the external environment in which the electronic device is located. The connection may be direct connection or indirect connection.

[0082] In some embodiments, along the thickness direction of the electrical connector 330 (i.e., the direction from the bottom surface 3312 of the electrical connector 330 toward the top surface 3311), the opening 3315 can be arranged opposite to the insertion space 3314 (e.g., Figure 4c At this time, the opening 3315 can be directly connected to the insertion space 3314. The first electrical connection end of the terminal 332 can be exposed through the opening 3315 of the bottom surface 3312.

[0083] In other embodiments, along the thickness direction of the electrical connector 330, the opening 3315 can be staggered with the plug-in space 3314. In this case, the opening 3315 can be indirectly connected to the plug-in space 3314. For example, the insulating housing 331 can have a connecting channel. One end of the connecting channel is connected to the opening 3315, and the other end is connected to the plug-in space 3314. The opening 3315 can be indirectly connected to the plug-in space 3314 through the connecting channel. The first plug-in end 410 of the signal transmission structure 400 can enter the plug-in space 3314 through the opening 3315 and the connecting channel, and connect to the first electrical connection end of the terminal 332.

[0084] The second electrical connection end of the terminal 332 extends out through the bottom surface 3312 of the insulating housing 331 and is electrically connected to the circuit board 310. Exemplarily, the second electrical connection end of the terminal 332 may also extend out of the insulating housing 331 through the opening 3315 and connect to the circuit board 310 to achieve electrical connection with the circuit board 310. In some embodiments, the second electrical connection end of the terminal 332 may be electrically connected to the circuit board 310 by welding.

[0085] It is understandable that, combined with Figure 2 , Figure 3a and Figure 4cAs shown, the electrical connector 330 of the present application realizes electrical connection with the signal transmission structure 400 and the circuit board 310 by connecting the first electrical connection end and the second electrical connection end of the terminal 332 on one side of the bottom surface 3312 of the electrical connector 330, so that the signal transmission structure 400 can be fixed by using the cooperation of the circuit board 310 and the surrounding structure, and then compared with the ZIF connector or the BTB connector, the electrical connector 330 provided by the present application does not need to set up an additional pressing structure for fixing the signal transmission structure 400, which can effectively reduce the volume of the electrical connector 330, which is conducive to the miniaturization of the electronic device 1000 and reduces the cost. In addition, compared with the solution of connecting the signal transmission structure 400 from the top surface 3311 or the peripheral side surface 3313 of the electrical connector 330, the signal transmission structure 400 is connected from the bottom surface 3312 of the electrical connector 330, and the signal transmission structure 400 can be set close to the circuit board 310, and the arrangement of the signal transmission structure 400 is more compact, which is conducive to the miniaturization of the electronic device 1000.

[0086] For example, the signal transmission structure 400 can be laid between the circuit board 310 and the housing 100 (eg Figure 2 ). The electrical connector 330 is fixedly connected to a side surface of the circuit board 310 away from the housing 100, and the signal transmission structure 400 may be partially located between the circuit board 310 and the housing 100. The circuit board 310 and the housing 100 cooperate to support the signal transmission structure 400, thereby achieving the fixation of the signal transmission structure 400. Exemplarily, the circuit board 310 may be provided with a first through hole 311, and the first through hole 311 is arranged opposite to the bottom surface 3312 of the electrical connector 330. The first plug-in end 410 of the signal transmission structure 400 may pass through the circuit board 310 through the first through hole 311 and be electrically connected to the terminal 332.

[0087] like Figure 3a and Figure 4cAs shown, the terminal 332 may include a first terminal 334 and a second terminal 335. The first terminal 334 may have a first electrical connection end 3341 electrically connected to the signal transmission structure 400 and a second electrical connection end 3342 electrically connected to the circuit board 310. The second terminal 335 may also have a third electrical connection end 3351 electrically connected to the signal transmission structure 400 and a fourth electrical connection end 3352 electrically connected to the circuit board 310. Part of the first electrical connection end 3341 of the first terminal 334 and part of the third electrical connection end 3351 of the second terminal 335 are arranged opposite to each other. Part of the first electrical connection end 3341 of the first terminal 334 and part of the third electrical connection end 3351 of the second terminal 335 are located in the plug-in space 3314, and are used to electrically connect the first plug-in end 410 of the signal transmission structure 400. When the first plug-in end 410 is plugged into the plug-in space 3314 , the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 may be connected to two sides of the first plug-in end 410 , respectively.

[0088] It can be understood that the terminal 332 includes a technical solution of a first terminal 334 and a second terminal 335, and the first plug-in end 410 of the signal transmission structure 400 can realize double-sided signal output. When the number of terminals 332 remains unchanged, compared with the solution of single-sided signal output, the volume of the electrical connector 330 can be effectively reduced, which is conducive to the miniaturization of the electronic device 1000. In addition, the solution of double-row terminals 332 can be compatible with both the signal transmission structure 400 with single-sided signal output and the signal transmission structure 400 with double-sided signal output, and the application scenario of the electrical connector 330 is less restricted. When the signal transmission structure 400 outputs double-sided signals, contact areas are provided on both sides of the first plug-in end 410, and the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 are respectively connected to the contact areas on both sides of the first plug-in end 410.

[0089] In other embodiments, the signal transmission structure 400 can also be laid between the circuit board 310 and the electrical connector 330 (not shown), in which case the signal transmission structure 400 is partially located between the insulating housing 331 of the electrical connector 330 and the circuit board 310, and the electrical connector 330 can cooperate with the circuit board 310 to hold the signal transmission structure 400, thereby fixing the signal transmission structure 400. It is understandable that, compared with the solution in which the signal transmission structure 400 is laid between the circuit board 310 and the electrical connector 330, the signal transmission structure 400 is laid between the circuit board 310 and the housing 100, and the side of the circuit board 310 away from the housing 100 does not need to avoid the signal transmission structure 400. On the one hand, while the number of electronic components 320 on the circuit board 310 remains unchanged, the area of ​​the circuit board 310 can be reduced, which is beneficial to the miniaturization of the electronic device 1000. On the other hand, the area of ​​the circuit board 310 originally used to avoid the signal transmission structure 400 can be used to set the electronic components 320, and more functional components can be arranged in a limited space, which is beneficial to the multifunctionality of the electronic device 1000.

[0090] In other embodiments, when the circuit board 310 is mounted on other internal structural components of the electronic device 1000 , the signal transmission structure 400 may be laid between the circuit board 310 and the housing of the structural component.

[0091] Figure 5 yes Figure 3a A partial cross-sectional view of an embodiment of the structure shown in FIG. 1 at section line BB.

[0092] like Figure 5 As shown, the first electrical connection end 3341 of the first terminal 334 can be a metal spring. When the first terminal 334 is connected to the signal transmission structure 400, the first electrical connection end 3341 of the first terminal 334 can abut against the first plug-in end 410 of the signal transmission structure 400. In this way, the risk of displacement of the signal transmission structure 400 can be reduced, and the reliability of the electrical connection between the first terminal 334 and the signal transmission structure 400 is better. Exemplarily, the first electrical connection end 3341 of the first terminal 334 can be "V" shaped, "U" shaped, "S" shaped, wavy or paper clip shaped.

[0093] Exemplarily, when the first terminal 334 abuts against the first plug end 410 of the signal transmission structure 400, the first electrical connection end 3341 of the first terminal 334 is deformed. Part of the first electrical connection end 3341 of the first terminal 334 may be located in the first movable space 3316. The first movable space 3316 is used to provide space for the deformation of the first electrical connection end 3341 of the first terminal 334 when the first terminal 334 abuts against the first plug end 410 of the signal transmission structure 400. In other embodiments, the insulating housing 331 may not be provided with the first movable space 3316, and the part of the first terminal 334 located in the first movable space 3316 may be embedded in the insulating housing 331.

[0094] Exemplarily, the first electrical connection end 3341 of the first terminal 334 may be located at a side of the plug-in space 3314 away from the second electrical connection end 3342 of the first terminal 334. When the first plug-in end 410 of the signal transmission structure 400 is plugged into the plug-in space 3314, the first electrical connection end 3341 of the first terminal 334 and the second electrical connection end 3342 of the first terminal 334 are respectively located at two sides of the first plug-in end 410. The first terminal 334 may be partially located in the first active space 3316, and partially located in the second active space 3317 arranged opposite to the first active space 3316.

[0095] It can be understood that, compared with the first electrical connection end 3341 of the first terminal 334 and the second electrical connection end 3342 of the first terminal 334 being located on the same side of the first plug-in end 410, the first electrical connection end 3341 of the first terminal 334 and the second electrical connection end 3342 of the first terminal 334 are respectively located on both sides of the first plug-in end 410. When the first terminal 334 is against the first plug-in end 410 of the signal transmission structure 400, the deformation of the first terminal 334 can be more evenly distributed to various positions of the first terminal 334, the deformation force applied to the first terminal 334 is more uniform, the service life of the first terminal 334 is longer, and the reliability of the electrical connection between the electrical connector 330 and the signal transmission structure 400 is better.

[0096] Figure 6 yes Figure 3a A partial cross-sectional view of one embodiment of the structure shown in FIG. 1 at section line CC.

[0097] like Figure 6As shown, the third electrical connection end 3351 of the second terminal 335 can also be a metal spring. When the second terminal 335 is connected to the signal transmission structure 400, the third electrical connection end 3351 of the second terminal 335 can abut against the first plug-in end 410 of the signal transmission structure 400. In this way, the risk of displacement of the signal transmission structure 400 can also be reduced, and the reliability of the electrical connection between the second terminal 335 and the signal transmission structure 400 is better. Exemplarily, the third electrical connection end 3351 of the second terminal 335 can be a "V"-shaped, "U"-shaped electrical connection end, and the shape can be the same or different.

[0098] Exemplarily, when the second terminal 335 abuts against the first plug end 410 of the signal transmission structure 400, the third electrical connection end 3351 of the second terminal 335 is deformed. Part of the third electrical connection end 3351 of the second terminal 335 may be located in the second active space 3317. The second active space 3317 is used to provide space for the deformation of the third electrical connection end 3351 of the second terminal 335 when the second terminal 335 abuts against the first plug end 410 of the signal transmission structure 400. In other embodiments, the second terminal 335 may also be partially embedded in the insulating housing 331, that is, in this case, the insulating housing 331 may not be provided with the second active space 3317, and the part of the second terminal 335 located in the second active space 3317 may be embedded in the insulating housing 331.

[0099] Analogously to the arrangement of the first terminal 334, the third electrical connection end 3351 of the second terminal 335 may also be located at a side of the insertion space 3314 away from the second electrical connection end of the second terminal 335. The second terminal 335 may be partially located in the first active space 3316, and partially located in the second active space 3317 arranged opposite to the first active space 3316. In this way, the deformation force on each part of the second terminal 335 is more uniform, the service life of the second terminal 335 is longer, and the electrical connection reliability of the electrical connector 330 is better.

[0100] In other embodiments, the first terminal 334 may be a metal spring sheet as a whole. The second terminal 335 may be a metal spring sheet as a whole. For example, a metal strip having a certain shape may be formed by a process such as cutting, and then the first terminal 334 and the second terminal 335 having a specific bending shape may be formed by a bending process.

[0101] In some embodiments, when the signal transmission structure 400 is routed between the circuit board 310 and the insulating housing 331, the position where the second electrical connection end 3342 of the first terminal 334 or the fourth electrical connection end 3352 of the second terminal 335 protrudes from the bottom surface 3312 of the insulating housing 331 can avoid the signal transmission structure 400. Exemplarily, when the signal transmission structure 400 is routed from the side where the first electrical connection end 3341 of the first terminal 334 is located, the fourth electrical connection end 3352 of the second terminal 335 and the second electrical connection end 3342 of the first terminal 334 can be located on the same side of the insertion space 3314 to avoid interference between the fourth electrical connection end 3352 of the second terminal 335 and the signal transmission structure 400.

[0102] The number of the first terminal 334 may be one or more. The number of the second terminal 335 may be one or more. The number of the first terminal 334 and the number of the second terminal 335 may be equal or unequal. Exemplarily, the number of the first terminal 334 is multiple, and the multiple first terminals 334 are arranged at intervals along the extension direction of the plug-in space 3314. The number of the second terminal 335 may also be multiple, and the multiple second terminals 335 are arranged at intervals along the extension direction of the plug-in space 3314.

[0103] In some embodiments, along the extension direction of the plug-in space 3314, the projection of the first electrical connection end 3341 of the first terminal 334 on the reference plane and the projection of the third electrical connection end 3351 of the second terminal 335 on the reference plane partially overlap, and the reference plane is perpendicular to the extension direction of the plug-in space 3314. In this way, the volume of the electrical connector 330 can be further reduced, which is conducive to the miniaturization of the electronic device 1000. Exemplarily, along the extension direction of the plug-in space 3314, multiple first terminals 334 and multiple second terminals 335 can be arranged alternately. That is, one second terminal 335 is arranged between any two adjacent first terminals 334, and one first terminal 334 is arranged between any two adjacent second terminals 335.

[0104] In other embodiments, the electrical connector 330 may include only one of the first terminal 334 and the second terminal 335. When the signal transmission structure 400 is plugged into the electrical connector 330, the first terminal 334 or the second terminal 335 abuts against one side of the first plugging end 410 of the signal transmission structure 400.

[0105] like Figure 4b As shown, the second side wall 3365 of the receiving groove 3319 may be recessed in a direction away from the first side wall 3364 to form a first groove 3310. The opening of the first groove 3310 may be located on the second side wall 3365. The first groove 3310 may communicate with the second activity space 3317.

[0106] Figure 7 yes Figure 4c The electrical connector 330 shown in FIG. 1 is a cross-sectional view of an embodiment at a section line DD at another angle.

[0107] like Figure 4a and Figure 7 As shown, the first terminal 334 may also include a convex portion 3344. When the first terminal 334 is fixedly connected to the insulating housing 331, the convex portion 3344 may be located in the first groove 3310, and the convex portion 3344 of the first terminal 334 may form a concave-convex matching relationship with the first groove 3310. In the process of installing the first terminal 334 to the insulating housing 331, the setting of the convex portion 3344 may assist in positioning and improve assembly efficiency. In other embodiments, the convex portion 3344 of the first terminal 334 may also be interference fit with the wall surface of the first groove 3310 to achieve the fixed connection of the first terminal 334 to the insulating housing 331. The second terminal 335 may also be provided with a convex portion. The specific setting of the convex portion of the second terminal 335 and the way in which the second terminal 335 is fixed to the insulating housing 331 may refer to the setting of the convex portion 3344 of the first terminal 334, which will not be repeated here.

[0108] In some embodiments, when the first terminal 334 is an integrally formed metal terminal, a metal strip having a protrusion may be first formed by cutting, die-casting, or the like, and then the first terminal 334 having the protrusion 3344 may be formed by a bending process.

[0109] In some embodiments, multiple first terminals 334 can be connected by an insulating member (not shown), and multiple first terminals 334 form a structural member. In the process of installing the first terminal 334 to the insulating housing 331, on the one hand, the insulating member can be used as a positioning structure, and a groove is provided in the receiving groove 3319 for assembly and positioning between the first terminal 334 and the insulating housing 331. On the other hand, the number of installations of the first terminal 334 can be reduced, and multiple first terminals 334 can be installed on the insulating housing 331 at one time. In some embodiments, multiple second terminals 335 can also be connected by an insulating member (not shown), and multiple first terminals 334 form a structural member.

[0110] In other embodiments, when the first terminal 334 and the second terminal 335 are embedded in the insulating housing 331, the first terminal 334 and the second terminal 335 may not be provided with a convex portion. The structural shape of the first terminal 334 and the second terminal 335 can be set according to requirements, and the first terminal 334 and the second terminal 335 in the drawings of the present application are only examples of one embodiment.

[0111] Figure 8 yes Figure 3aA partial cross-sectional view of an embodiment of the structure shown in FIG. 1 at section line EE.

[0112] like Figure 3a and Figure 8 As shown, the reinforcing member 333 has a first portion 3331 fixedly connected to the insulating housing 331 and a second portion 3332 fixedly connected to the circuit board 310. The first portion 3331 and the second portion 3332 can be arranged at intervals. It can be understood that the electrical connector 330 can be provided with the reinforcing member 333 to enhance the connection reliability between the electrical connector 330 and the circuit board 310, thereby improving the reliability of the electrical connection between the electrical connector 330 and the signal transmission structure 400.

[0113] Exemplarily, the reinforcing member 333 may be a structural member made of a metal material, so that the reinforcing member 333 may be fixedly connected to the circuit board 310 by welding. For example, the reinforcing member 333 may be made of a metal material such as aluminum, steel or copper.

[0114] The reinforcing piece 333 can be fixedly connected to the insulating housing 331 by means of concave-convex matching. For example, the insulating housing 331 can include a concave portion 337, and the shape of the concave portion 337 can match the first portion 3331. In this way, the first portion 3331 can be located in the concave portion 337, and the first portion 3331 can form a concave-convex matching relationship with the concave portion 337, so that the reinforcing piece 333 is fixedly connected to the insulating housing 331. In other embodiments, the reinforcing piece 333 can also be fixedly connected to the insulating housing 331 by means of gluing, screw connection, etc.

[0115] The number of reinforcing pieces 333 may be one or more. Exemplarily, the number of reinforcing pieces 333 is two, and the two reinforcing pieces 333 are located on both sides of the plug-in space 3314. In this way, the force on the electrical connector 330 is relatively balanced. In other embodiments, the reinforcing piece 333 may also be fixedly connected to other positions of the insulating housing 331, which will be described in detail later through the drawings and will not be repeated here.

[0116] The reinforcing piece 333 may be "U" shaped, and the two legs of the "U" shape may be used to be fixedly connected to the circuit board 310, that is, one reinforcing piece 333 and the circuit board 310 may have two second parts 3332, and the two second parts 3332 are located on the same side of the insertion space 3314. In other embodiments, the two second parts 3332 may also be located on both sides of the insertion space 3314.

[0117] In other embodiments, the reinforcing member 333 and the insulating housing 331 may be formed into an integral structural member by insert molding. Insert molding refers to a molding process in which a pre-prepared insert is placed in a mold and then molten material is injected, and the molten material is bonded and solidified with the insert to form an integrated product.

[0118] In other embodiments, the electrical connector 330 may not be provided with the reinforcing piece 333, and the insulating housing 331 is fixedly connected to the circuit board 310 by gluing or the like. It is understandable that, compared with the gluing method, by providing the reinforcing piece 333, the insulating housing 331 is not easy to fall off from the circuit board 310, and the connection reliability between the insulating housing 331 and the circuit board 310 is better.

[0119] Fig. 9 yes Figure 3a A partial cross-sectional view of one embodiment of the structure shown in FIG. 1 at section line FF.

[0120] like Figure 3b and Fig. 9 As shown, the insulating housing 331 has a positioning structure. The positioning structure can be used to assist positioning during the installation of the circuit board assembly 300 to improve the efficiency of the installation. The positioning structure can be a through hole or a groove. Exemplarily, the insulating housing 331 is provided with a through hole 338, and the two openings 3381 of the through hole 338 are respectively located on the top surface 3311 and the bottom surface 3312 of the insulating housing 331. When the circuit board 310 is fixedly connected to the housing 100, the electronic device 1000 may include a positioning column 110, and the positioning column 110 may be fixedly connected to the inner surface of the housing 100, that is, the positioning column 110 and the circuit board 310 are installed on the same side of the housing 100. The circuit board 310 may be provided with a second through hole 312, and the second through hole 312 and the through hole 338 are arranged opposite to each other. The positioning column 110 is located in the second through hole 312 and the through hole 338. The first through hole 311 and the second through hole 312 may be arranged at intervals or may be connected. When the circuit board 310 is installed on other structural parts, the positioning column 110 can be fixedly connected to the other structural parts, that is, the setting position of the positioning column 110 can be adjusted according to the installation position of the circuit board 310, so as to facilitate the positioning column 110 to assist in positioning during the installation of the circuit board assembly 300, thereby improving the installation efficiency of the circuit board assembly 300.

[0121] In other embodiments, the positioning structure may also be a convex block structure, and in this case, the housing 100 may be provided with a groove matching the positioning structure, thereby achieving a rapid positioning effect.

[0122] In some embodiments, the same technical contents as those of the electrical connector 330 in the previous embodiments are not repeated. Fig.10 yes Figure 2A structural schematic diagram of another embodiment of an electrical connector 330 is shown in FIG. Fig.11 yes Fig.10 The electrical connector 330 shown in FIG. 1 is a cross-sectional view of an embodiment at a section line GG at another angle.

[0123] like Fig.10 and Fig.11 As shown, the electrical connector 330 may include an insulating housing 331, a terminal 332, and a reinforcing member 333. The insulating housing 331 includes a top surface 3311 and a bottom surface 3312 that are arranged opposite to each other. The terminal 332 is fixedly connected to the insulating housing 331. The terminal 332 has a first electrical connection end electrically connected to the signal transmission structure 400 and a second electrical connection end electrically connected to the circuit board 310. The first electrical connection end of the terminal 332 is exposed at the bottom surface 3312 of the insulating housing 331 for electrically connecting the signal transmission structure 400, and the second electrical connection end of the terminal 332 extends through the bottom surface 3312 of the insulating housing 331 for electrically connecting to the circuit board 310.

[0124] Exemplarily, the insulating housing 331 has an insertion space 3314 . The insertion space 3314 can be used to accommodate the first insertion end 410 of the signal transmission structure 400 . The bottom surface 3312 of the insulating housing 331 is provided with an opening 3315 , and the opening 3315 is connected to the insertion space 3314 .

[0125] Exemplarily, the terminal 332 may include a first terminal 334 and a second terminal 335. The first terminal 334 may have a first electrical connection end 3341 electrically connected to the signal transmission structure 400 and a second electrical connection end 3342 electrically connected to the circuit board 310. The second terminal 335 may also have a third electrical connection end 3351 electrically connected to the signal transmission structure 400 and a fourth electrical connection end 3352 electrically connected to the circuit board 310. Part of the first electrical connection end 3341 of the first terminal 334 and part of the third electrical connection end 3351 of the second terminal 335 are located in the plug-in space 3314, and are used to electrically connect the first plug-in end 410 of the signal transmission structure 400.

[0126] Part of the first electrical connection end 3341 of the first terminal 334 and part of the third electrical connection end 3351 of the second terminal 335 can be located on both sides of the plug-in space 3314. When the first plug-in end 410 of the signal transmission structure 400 is plugged into the plug-in space 3314, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 can be connected to both sides of the signal transmission structure 400, respectively. In this way, the first plug-in end 410 of the signal transmission structure 400 can realize double-sided signal transmission. When the number of terminals 332 remains unchanged, compared with the single-sided signal transmission solution, the volume of the electrical connector 330 can be effectively reduced, which is conducive to the miniaturization of the electronic device 1000. In addition, the solution of double-row terminals 332 can also be compatible with the signal transmission structure 400 with single-sided signal output, and the application restrictions of the electrical connector 330 are smaller.

[0127] In some embodiments, the first electrical connection end 3341 of the first terminal 334 and the second electrical connection end 3342 of the first terminal 334 may be located on the same side of the plug-in space 3314. The third electrical connection end 3351 of the second terminal 335 and the second electrical connection end of the second terminal 335 may be located on the same side of the plug-in space 3314. When the first plug-in end 410 of the signal transmission structure 400 is plugged into the electrical connector 330, the first terminal 334 and the second terminal 335 are located on both sides of the first plug-in end 410, respectively.

[0128] The first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 can be metal springs. Exemplarily, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 are wavy. It is understandable that the shapes of the first terminal 334 and the second terminal 335 can be designed according to requirements, and this application does not limit them.

[0129] In some embodiments, the insulating housing 331 may further have a first active space 3316 and a second active space 3317. The first active space 3316 and the second active space 3317 are both connected to the plug-in space 3314 and are respectively located on both sides of the plug-in space 3314. The arrangement of the plug-in space 3314, the first active space 3316, and the second active space 3317 may refer to the arrangement of the plug-in space 3314, the first active space 3316, and the second active space 3317 in the embodiment shown above, and will not be repeated here.

[0130] Part of the first terminal 334 may be located in the first active space 3316. Part of the second terminal 335 may be located in the second active space 3317. In this way, when the signal transmission structure 400 is plugged into the electrical connector 330, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 are held against the signal transmission structure 400, the first active space 3316 may provide space for the deformation of the first terminal 334, and the second active space 3317 may provide space for the deformation of the second terminal 335.

[0131] In some embodiments, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 may be arranged opposite to each other. That is, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 may be arranged completely opposite to each other, or may be arranged partially opposite to each other. Exemplarily, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 are arranged completely opposite to each other. In other embodiments, the first electrical connection end 3341 of the first terminal 334 and the third electrical connection end 3351 of the second terminal 335 may also be staggered.

[0132] In some embodiments, along the extension direction of the plug-in space 3314, the projection of the first electrical connection end 3341 of the first terminal 334 on the reference plane partially overlaps with the projection of the third electrical connection end 3351 of the second terminal 335 on the reference plane, and the reference plane is perpendicular to the extension direction of the plug-in space 3314. In this way, the width of the electrical connector 330 in the first direction can be further reduced, and the volume of the electrical connector 330 can be reduced, which is conducive to the miniaturization of the electronic device 1000.

[0133] The number of reinforcing members 333 may be two. The two reinforcing members 333 are arranged at intervals along the extension direction of the plug-in space 3314. The two second parts 3332 of the reinforcing member 333 may be located on both sides of the plug-in space 3314. The two reinforcing members 333 are fixedly connected to both ends of the insulating housing 331. It is understood that the number, shape and connection position of the reinforcing members 333 with the insulating housing 331 can be designed according to actual needs, and this application does not impose any restrictions.

[0134] The present application introduces several different structures of electrical connectors 330 in conjunction with the accompanying drawings. The electrical connector 330 is electrically connected between the circuit board 310 and the signal transmission structure 400, and is used to realize the electrical connection between the signal transmission structure 400 and the circuit board 310. The electrical connector 330 includes an insulating housing 331 and a terminal 332, the terminal 332 is fixedly connected to the insulating housing 331, the first electrical connection end of the terminal 332 is exposed at the bottom surface 3312 of the insulating housing 331, and is used to electrically connect the signal transmission structure 400, the second electrical connection end of the terminal 332 extends through the bottom surface 3312 of the insulating housing 331, and is used to electrically connect the circuit board 310, and the bottom surface 3312 of the insulating housing 331 faces the circuit board 310. The signal transmission structure 400 can be electrically connected to the terminal 332 via the bottom surface 3312 of the electrical connector 330.

[0135] When the signal transmission structure 400 is laid between the electrical connector 330 and the circuit board 310, it enters the receiving groove 3319 through the opening 3315 to electrically connect the terminal 332. At this time, the signal transmission structure 400 is partially located between the circuit board 310 and the electrical connector 330, and the insulating housing 100 of the electrical connector 330 can cooperate with the circuit board 310 to support the signal transmission structure 400, thereby fixing the signal transmission structure 400. In this way, compared with the BTB connector or the ZIF connector, the electrical connector 330 of the present application does not need to be additionally provided with a pressing structure, which effectively reduces the volume of the electrical connector 330 and is conducive to the miniaturization of the electronic device 1000.

[0136] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. In other words, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0137] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.

[0138] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
