[0029] In some embodiments, the electronic device may also be a data line.

[0030] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of an electronic device in some embodiments of the present application, Figure 2 yes Figure 1Schematic diagram of the exploded structure of the electronic device in some embodiments in the illustrated embodiment. The electronic device 100 may include a middle frame 101, a rear shell 102 disposed on one side of the middle frame 101 and connected to the middle frame 101 to form an accommodating space 1010, a circuit board 103 disposed in the accommodating space 1010, an electrical connector 104 disposed in the accommodating space 1010, and a display screen 105 disposed on the side of the middle frame 101 away from the rear shell 102. Among them, the middle frame 101 can be connected to the rear shell 102 to form an accommodating space 1010. The circuit board 103 and the electrical connector 104 are disposed in the accommodating space 1010. The circuit board 103 can be connected to the electrical connector 104. The electrical connector 104 can be connected to the outside of the accommodating space 1010, for example, the electrical connector 104 is connected to the connecting line, so as to realize the charging function and data interaction function of the electronic device 100. For example, the electrical connector 104 is connected to the connector of the connecting line, so as to realize the charging function and data interaction function of the electronic device 100. For example, the electrical connector 104 and the connecting wire, such as the connector, are plugged in and out to achieve connection, thereby realizing the charging function and data exchange function of the electronic device 100. At the same time, the electrical connector 104 can have waterproof performance during use. The display screen 105 can be used to provide image display for the electronic device 100.

[0031] See also Figure 2 , the middle frame 101 may include a middle plate 1011 and a frame 1012 surrounding the middle plate 1011. In some embodiments, the middle plate 1011 and the frame 1012 may be two independent structural members. The middle plate 1011 may be connected and fixed to the frame 1012 by assembly methods such as snap-on, screw-on, bonding, injection molding or welding. Of course, other methods may also be used for connection and fixing. In some embodiments, the middle plate 1011 may be an integral structure with the frame 1012. For example, the middle plate 1011 and the frame 1012 may be integrally formed by injection molding, stamping molding or heat absorption molding.

[0032] In some embodiments, the frame 1012 may be formed by extending the sidewall of the middle plate 1011 in the thickness direction of the middle plate 1011. The middle plate 1011 may cooperate with the frame 1012 and the rear shell 102 to form the accommodation space 1010.

[0033] The accommodating space 1010 can not only be used to install the circuit board 103 and the electrical connector 104 , but can also be used to install functional devices such as cameras, batteries, and sensors to realize various functional applications of the electronic device 100 .

[0034] The middle plate 1011 may be used to install the circuit board 103 and the electrical connector 104 , so that the circuit board 103 and the electrical connector 104 may be fixed in the accommodating space 1010 .

[0035] The frame 1012 may be provided with a through slot 1013 connecting the inside of the accommodating space 1010 and the outside of the accommodating space 1010 , so that a connecting wire, such as a connector, can be connected to the electrical connector 104 in the accommodating space 1010 through the through slot 1013 to realize the charging function and data interaction function of the electronic device 100 .

[0036] For example, the electrical connector 104 may be in contact with the frame 1012, so that the frame 1012 may be provided with a through slot 1013 at a corresponding position to connect the electrical connector 104, thereby realizing the connection between the electrical connector 104 and the outside of the accommodation space 1010. At the same time, part of the electrical connector 104 may be arranged in the through slot 1013, so that a sealing ring may be arranged between the electrical connector 104 and the inner wall of the through slot 1013 to ensure the sealing of the electronic device 100, and the sealing may further ensure the waterproof and dustproof performance of the electronic device 100. In some embodiments, the through slot 1013 may be square in shape to fit the connector of the mainstream connecting wire on the market. In some embodiments, the through slot 1013 may also be circular or any other shape in shape, and only the connecting wire, such as the connector, may be connected to the electrical connector 104 in the accommodation space 1010 through the through slot 1013.

[0037] The rear shell 102 can be used to protect the functional components arranged in the accommodating space 1010. The rear shell 102 can be covered on the side of the middle frame 101, such as the frame 1012, which is away from the display screen 105, so as to enclose the accommodating space 1010 together with the middle frame 101. In some embodiments, the material of the middle frame 101 and / or the rear shell 102 can be glass, metal, hard plastic, etc., so that the middle frame 101 and / or the rear shell 102 have a certain structural strength. At the same time, since the middle frame 101 and the rear shell 102 are generally directly exposed to the external environment, the middle frame 101 and the rear shell 102 can have certain wear resistance, corrosion resistance, scratch resistance and other properties, or a layer of functional material for wear resistance, corrosion resistance and scratch resistance can be applied on the outer surface of the middle frame 101 and the rear shell 102 (that is, the outer surface of the electronic device 100). In addition, in some embodiments, the middle frame 101 and the rear shell 102 can be designed with the same color to improve the appearance expression of the electronic device 100. In other embodiments, the middle frame 101 and the rear shell 102 may also be designed in different colors to show different appearance effects. At the same time, corresponding brand logos (LOGOs) may also be set on the middle frame 101 and the rear shell 102 to beautify the appearance of the electronic device 100 and improve brand recognition.

[0038] The display screen 105 can be disposed on the side of the middle frame 101, such as the frame 1012, away from the rear housing 102. The display screen 105 can be an AMOLED (Active-matrix organic light emitting diode) display screen, a Micro LED (micro light emitting diode) display screen, or even an LCD (Liquid Crystal Display) display screen or a QLED (Quantum dots Light-emitting Diodes) display screen, and the type of the display screen 105 is not limited.

[0039] The display screen 105 can be a flat screen, a hyperbolic screen, or a quad-curved screen in appearance, and the appearance of the display screen 105 is not limited. It should be noted that the above-mentioned flat screen means that the display screen 105 is set in a flat shape as a whole; the above-mentioned hyperbolic screen means that the left and right edge areas of the display screen 105 are set in a curved shape, and the other areas are still set in a flat shape, which can not only reduce the black edge of the display screen 105 and increase the visible area of ​​the display screen 105, but also increase the appearance and grip of the electronic device 100; the above-mentioned quad-curved screen means that the upper, lower, left and right edge areas of the display screen 105 are all set in a curved shape, and the other areas are still set in a flat shape, which can not only further reduce the black edge of the display screen 105 and increase the visible area of ​​the display screen 105, but also further increase the appearance and grip of the electronic device 100.

[0040] It is understandable that all directional indications in the embodiments (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0041] In some embodiments, the display screen 105 may include a transparent cover plate 1051, a display cover plate 1052, and a touch panel 1053 that are stacked. The touch panel 1053 is disposed between the transparent cover plate 1051 and the display cover plate 1052. The transparent cover plate 1051 is mainly used to protect the display cover plate 1052 and can be used as the outer surface of the electronic device 100. At the same time, the surface of the transparent cover plate 1051 also has a flat and smooth characteristic, so that the user can perform touch operations such as clicking, sliding, and pressing. Among them, the material of the transparent cover plate 1051 can be a rigid material such as glass, or a flexible material such as polyimide (PI), colorless polyimide (CPI), etc. The display cover plate 1052 is mainly used to display the screen, and can be used as an interactive interface to instruct the user to perform the above-mentioned touch operations on the transparent cover plate 1051. The touch panel 1053 is mainly used to respond to the user's touch operation and convert the corresponding touch operation into an electrical signal to be transmitted to the processor of the electronic device 100, so that the electronic device 100 can respond to the user's touch operation accordingly. In some embodiments, the transparent cover 1051, the display cover 1052 and the touch panel 1053 can be bonded together with the help of colloids such as OCA (Optically Clear Adhesive) or PSA (Pressure Sensitive Adhesive). In addition, in some embodiments, the outer surface of the electronic device 100 (that is, the outer surface of the transparent cover 1051) can also be provided with any one of other functional film layers such as tempered film, frosted film, decorative film, anti-peep film, hydrogel film, etc., so that the electronic device 100 can provide different usage effects for users.

[0042] See also Figure 3 and Figure 4 , Figure 3 yes Figure 1 The schematic diagram of the structure of the electrical connector 104 in some embodiments shown in the embodiment, Figure 4 yes Figure 3 Schematic diagram of the exploded structure of the electrical connector 104 in the illustrated embodiment. The electrical connector 104 is an input / output interface that connects the electronic device 100 with an external device using a serial bus standard. The electrical connector 104 may be a Type-C connector to implement the charging function and data interaction function of the electronic device 100. The electrical connector 104 may be manufactured using the USB-IF (USB Implementers Forum) organization standard of USB Type-C, and interfaces such as the power interface, USB interface, DP interface, HDMI interface, and VGA interface may be uniformly carried by the electrical connector 104.

[0043] The electrical connector 104 may include a docking tongue plate 10, a connection terminal 20 disposed on the docking tongue plate 10, and a housing 30 connected to the docking tongue plate 10 and surrounded by the docking tongue plate 10 to form a plug-in space 3001. The docking tongue plate 10 and the connection terminal 20 may be disposed in the plug-in space 3001. The plug-in space 3001 may facilitate the plug-in and pull-out operation between the electrical connector 104 and a connecting wire, such as a connector. When the electrical connector 104 and a connecting wire, such as a connector, are plugged in and out, the connecting wire, such as a connector, may be inserted into the plug-in and pull-out space 3001 of the housing 30, the docking tongue plate 10 cooperates with the connecting wire, such as a connector, and the connection terminal 20 disposed on the docking tongue plate 10 contacts the terminal of the connecting wire, such as a connector, to achieve conduction between the electrical connector 104 and the connecting wire, such as a connector, thereby achieving the charging function and data interaction function of the electronic device 100.

[0044] See also Figure 3 and Figure 4 The docking tongue plate 10 can be made of insulating materials such as plastic, and can be arranged in the plug-in space 3001 and connected to the housing 30, so as to achieve the fixation of the docking tongue plate 10 and the housing 30. At the same time, the docking tongue plate 10 can also be used to install the connecting terminal 20. When the connecting wire, such as a connector, enters the plug-in space 3001, the docking tongue plate 10 can contact the connecting wire, such as the connector, and then the connecting terminal 20 on the docking tongue plate 10 contacts the connecting wire, such as the connector, to achieve the conduction between the electrical connector 104 and the connecting wire, such as the connector, so as to achieve the charging function and data interaction function of the electronic device 100.

[0045] See also Figure 5 and Figure 6 , Figure 5 yes Figure 4 The embodiment shown is a schematic diagram of the exploded structure of the docking tongue plate 10 and the connecting terminal 20 in some embodiments when they are matched. Figure 6 yes Figure 5 A schematic diagram of the exploded structure of the docking tongue plate 10 and the connecting terminal 20 in another perspective when they are matched in the illustrated embodiment. The docking tongue plate 10 may include a tongue core 11 for setting the connecting terminal 20, a reinforcement layer 12 arranged on the surface of the tongue core 11 to expose the connecting terminal 20, and a waterproof rubber block 13 arranged at the tail end of the tongue core 11. The tongue core 11 can be used to fix and install the connecting terminal 20. The reinforcement layer 12 is formed on the surface of the tongue core 11, and can expose the connecting terminal 20, thereby facilitating the contact and conduction between the connecting terminal 20 and the connecting wire, such as a connector. The reinforcement layer 12 can reinforce the tongue core 11, and can also cooperate with the tongue core 11 to fix the connecting terminal 20, and can also improve the waterproof performance of the tongue core 11. The waterproof rubber block 13 can be arranged at the tail end of the tongue core 11 to waterproof the tongue core 11, reduce the possibility of water entering the electronic device 100 from the gap between the tongue core 11 and the connecting terminal 20, and improve the waterproof performance.

[0046] The tongue core 11 can be made by injection molding, stamping molding or heat absorption molding. The tongue core 11 can be a plate-shaped structure. The tongue core 11 can include a first tongue plate 111, a second tongue plate 112 that is mutually buckled with the first tongue plate 111 in the thickness direction of the tongue core 11, and a clamping strip 113 arranged between the first tongue plate 111 and the second tongue plate 112. The first tongue plate 111 and the second tongue plate 112 cooperate to fix and install the connecting terminal 20.

[0047] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should be understood by people with ordinary skills in the field to which this application belongs. The words "first", "second" and similar words used in this application specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one" or "one" do not indicate a quantitative limitation, but indicate the existence of at least one. "Multiple" or "several" means two or more.

[0048] The first tongue plate 111 may be a plate-shaped structure. The first tongue plate 111 may include a first sub-base portion 114, a first sub-extending portion 115, and a first sub-tongue plate portion 116 that are sequentially connected and respectively buckled with the second tongue plate 112. The first sub-base portion 114, the first sub-extending portion 115, and the first sub-tongue plate portion 116 cooperate to install the connection terminal 20.

[0049] The first sub-base portion 114 can be buckled with the second tongue plate 112. In some embodiments, the first sub-base portion 114 is provided with an embedded steel sheet 1141 on the side away from the second tongue plate 112 to be fixedly connected to the housing 30. In some embodiments, the side of the first sub-base portion 114 away from the first sub-extension portion 115 can serve as the tail end of the tongue core 11.

[0050] The first sub-extension portion 115 connects the first sub-base portion 114 and the first sub-tongue plate portion 116. In the thickness direction of the tongue core 11, the thickness of the first sub-extension portion 115 is smaller than the thickness of the first sub-base portion 114.

[0051] The first sub-extension portion 115 can be buckled with the second tongue plate 112. In some embodiments, see Figure 7 , Figure 7 yes Figure 4 The cross-sectional view of the electrical connector 104 at line VII-VII in the illustrated embodiment. A first pressure relief groove 1151 is provided on one side of the first sub-extension portion 115 close to the second tongue plate 112 to cooperate with the second tongue plate 112 to form a pressure relief space 1001 to improve the waterproof performance of the tongue plate 10, reduce the possibility of water entering the electronic device 100 from the gap between the tongue core 11 and the connection terminal 20, and improve the waterproof performance.

[0052] See also Figure 5 and Figure 6 The first sub-extension portion 115 is provided with a first mounting hole 1152 connected to the first pressure relief groove 1151 for mounting the connection terminal 20. The first mounting hole 1152 may extend on the first sub-extension portion 115 and may extend to the first sub-base portion 114 and the first sub-tongue portion 116, so that the first mounting hole 1152 may also be provided on the first sub-base portion 114 and the first sub-tongue portion 116, and further the first sub-base portion 114 and the first sub-tongue portion 116 may mount the connection terminal 20 through the first mounting hole 1152. Furthermore, the pressure relief space 1001, such as the first pressure relief groove 1151, may reduce the possibility of water entering the electronic device 100 from the first mounting hole 1152, and improve the waterproof performance.

[0053] In some embodiments, when the electrical connector 104 is plugged in or out with a connection line such as a connector, the connection line such as a connector enters the plug-in space 3001, so that the air pressure in the plug-in space 3001 increases. When there is water in the plug-in space 3001, the water may have a chance to enter the electronic device 100 through the first mounting hole 1152 such as the gap between the tongue core 11 and the connection terminal 20 under the action of air pressure, and the provision of the pressure relief space 1001 such as the first pressure relief groove 1151 can store and hinder water, increase the difficulty of water entering the electronic device 100, and further improve the waterproof performance of the electrical connector 104. In addition, the pressure relief space 1001 such as the first pressure relief groove 1151 can also hinder water by smoothing the air pressure in the plug-in space 3001, increase the difficulty of water entering the electronic device 100, and further improve the waterproof performance of the electrical connector 104.

[0054] It can be understood that with the cooperation of the first tongue plate 111 and the connecting terminal 20, the amount of water that can enter the first mounting hole 1152, such as the gap between the tongue core 11 and the connecting terminal 20, is extremely low, and can even be ignored in some scenarios. In some scenarios, when water does not generate air pressure in the plug-in space 3001, it will not enter the first mounting hole 1152, such as the gap between the tongue core 11 and the connecting terminal 20, thereby making the pressure relief space 1001, such as the first pressure relief groove 1151, sufficient to play a waterproof role, thereby improving the waterproof performance of the electrical connector 104.

[0055] In addition, the provision of the pressure relief space 1001 , such as the first pressure relief groove 1151 , allows the electrical connector 104 to omit the glue dispensing process, thereby omitting the glue dispensing groove and the anti-glue overflow baffle, so that the length of the electrical connector 104 can be reduced.

[0056] In addition, the provision of the pressure relief space 1001 , such as the first pressure relief groove 1151 , allows the electrical connector 104 to omit the waterproof rubber block 13 while meeting the same waterproof requirement, thereby reducing the length of the electrical connector 104 .

[0057] In some embodiments, the pressure relief space 1001 , such as the first pressure relief groove 1151 , can enable the electrical connector 104 to have a waterproof rating of IPX8 when no glue dispensing process is performed.

[0058] In some embodiments, the first mounting hole 1152 may penetrate the first sub-base portion 114 and the first sub-tongue portion 116. In some embodiments, the first mounting hole 1152 may communicate with the outside at a side of the first sub-tongue portion 116 facing away from the second tongue 112. In some embodiments, the first mounting hole 1152 may communicate with the outside at a side of the first sub-tongue portion 116 facing away from the first sub-extension portion 115.

[0059] A reinforcement block 1153 may be provided on the surface of the first sub-extension portion 115 to cooperate with the reinforcement layer 12 .

[0060] The first sub-tongue plate portion 116 is connected to the first sub-extension portion 115 and is disposed on a side of the first sub-extension portion 115 away from the first sub-base portion 114. In some embodiments, in the thickness direction of the tongue core 11, the thickness of the first sub-tongue plate portion 116 is smaller than the thickness of the first sub-extension portion 115. In some embodiments, the side of the first sub-tongue plate portion 116 away from the first sub-extension portion 115 can serve as the head end of the tongue core 11.

[0061] The first sub-tongue plate portion 116 can be buckled with the second tongue plate 112. In some embodiments, a positioning groove 1161 is provided on one side of the first sub-tongue plate portion 116 close to the second tongue plate 112. The first sub-tongue plate portion 116 can be buckled with the second tongue plate 112 through the positioning groove 1161. In some embodiments, a positioning block 1162 is provided on one side of the first sub-tongue plate portion 116 close to the second tongue plate 112. The first sub-tongue plate portion 116 can be buckled with the second tongue plate 112 through the positioning block 1162. It can be understood that the positioning groove 1161 and / or the positioning block 1162 can be provided on the surface where the first sub-tongue plate portion 116 and the second tongue plate 112 cooperate, and the specific setting position may not be limited. In addition, the positioning groove 1161 and / or the positioning block 1162 can also be provided on the surface where the first sub-base portion 114 and the second tongue plate 112 cooperate. In addition, the positioning groove 1161 and / or the positioning block 1162 may also be disposed on the surface where the first sub-extension portion 115 cooperates with the second tongue plate 112 .

[0062] In some embodiments, a reinforcement groove 1163 is provided on the side of the first sub-tongue plate portion 116 facing away from the second tongue plate 112.

In some embodiments, a reinforcement block 1164 is provided on the side of the first sub-tongue plate portion 116 facing away from the second tongue plate 112. The first sub-tongue plate portion 116 can be connected and fixed to the reinforcement layer 12 through the reinforcement block 1164. It can be understood that the reinforcement groove 1163 and / or the reinforcement block 1164 can be set on the surface where the first sub-tongue plate portion 116 cooperates with the reinforcement layer 12, and the specific setting position may not be limited. In addition, the reinforcement groove 1163 and / or the reinforcement block 1164 can also be set on the surface where the first sub-base portion 114 cooperates with the reinforcement layer 12. In addition, the reinforcement groove 1163 and / or the reinforcement block 1164 can also be set on the surface where the first sub-extension portion 115 cooperates with the reinforcement layer 12.

[0063] The second tongue plate 112 may be a plate-shaped structure. The second tongue plate 112 may include a second sub-base portion 117, a second sub-extension portion 118, and a second sub-tongue plate portion 119 that are sequentially connected and respectively buckled with the first tongue plate 111. The second sub-base portion 117, the second sub-extension portion 118, and the second sub-tongue plate portion 119 cooperate to install the connection terminal 20.

[0064] The second sub-base portion 117 can be buckled with the first tongue plate 111, such as the first sub-base portion 114. In some embodiments, the second sub-base portion 117 is provided with an embedded steel sheet 1171 on a side away from the first tongue plate 111, such as the first sub-base portion 114, so as to be fixedly connected with the housing 30. In some embodiments, the side of the second sub-base portion 117 away from the second sub-extension portion 118 can serve as the tail end of the tongue core 11.

[0065] The second sub-extension portion 118 connects the second sub-base portion 117 and the second sub-tongue plate portion 119. In the thickness direction of the tongue core 11, the thickness of the second sub-extension portion 118 is smaller than the thickness of the second sub-base portion 117.

[0066] The second sub-extension portion 118 can be engaged with the first tongue plate 111, such as the first sub-extension portion 115. In some embodiments, see Figure 7 A second pressure relief groove 1181 is provided on one side of the second sub-extension portion 118 close to the first tongue plate 111, such as the first sub-extension portion 115, so that when the second sub-extension portion 118 is buckled with the first tongue plate 111, such as the first sub-extension portion 115, it cooperates with the first tongue plate 111, such as the first pressure relief groove 1151, to form a pressure relief space 1001, thereby further improving the waterproof performance of the docking tongue plate 10, reducing the possibility of water entering the electronic device 100 from the gap between the tongue core 11 and the connecting terminal 20, and improving the waterproof performance.

[0067] In some embodiments, the second sub-extension 118 is located on a side close to the first tongue plate 111, such as the first sub-extension 115, and a second pressure relief groove 1181 is provided in a portion corresponding to the first pressure relief groove 1151, so that the first pressure relief groove 1151 is connected to the second pressure relief groove 1181 to form a pressure relief space 1001.

[0068] See also Figure 5 and Figure 6 The second sub-extension portion 118 is provided with a second mounting hole 1182 communicating with the second pressure relief groove 1181 for mounting the connection terminal 20. The second mounting hole 1182 may extend on the second sub-extension portion 118 and may extend to the second sub-base portion 117 and the second sub-tongue portion 119, so that the second mounting hole 1182 may also be provided on the second sub-base portion 117 and the second sub-tongue portion 119, and further the second sub-base portion 117 and the second sub-tongue portion 119 may mount the connection terminal 20 through the second mounting hole 1182. Furthermore, the pressure relief space 1001, such as the second pressure relief groove 1181, may reduce the possibility of water entering the electronic device 100 from the second mounting hole 1182, and improve the waterproof performance.

[0069] In some embodiments, when the electrical connector 104 is plugged in or out with a connection line such as a connector, the connection line such as a connector enters the plug-in space 3001, so that the air pressure in the plug-in space 3001 increases. When there is water in the plug-in space 3001, the water may have a chance to enter the electronic device 100 through the second mounting hole 1182 such as the gap between the tongue core 11 and the connection terminal 20 under the action of air pressure, and the provision of the pressure relief space 1001 such as the second pressure relief groove 1181 can store and hinder water, increase the difficulty of water entering the electronic device 100, and further improve the waterproof performance of the electrical connector 104. In addition, the pressure relief space 1001 such as the second pressure relief groove 1181 can also hinder water by smoothing the air pressure in the plug-in space 3001, increase the difficulty of water entering the electronic device 100, and further improve the waterproof performance of the electrical connector 104.

[0070] It can be understood that with the cooperation of the second tongue plate 112 and the connecting terminal 20, the amount of water that can enter the second mounting hole 1182, such as the gap between the tongue core 11 and the connecting terminal 20, is extremely low, and can even be ignored in some scenarios. In some scenarios, when water does not generate air pressure in the plug-in space 3001, it will not enter the second mounting hole 1182, such as the gap between the tongue core 11 and the connecting terminal 20, thereby making the pressure relief space 1001, such as the second pressure relief groove 1181, sufficient to play a waterproof role, thereby improving the waterproof performance of the electrical connector 104.

[0071] In addition, the provision of the pressure relief space 1001 , such as the second pressure relief groove 1181 , allows the electrical connector 104 to omit the glue dispensing process, thereby omitting the glue dispensing groove and the anti-glue overflow baffle, so that the length of the electrical connector 104 can be reduced.

[0072] In addition, the provision of the pressure relief space 1001 , such as the second pressure relief groove 1181 , allows the electrical connector 104 to omit the waterproof rubber block 13 while meeting the same waterproof requirement, thereby reducing the length of the electrical connector 104 .

[0073] In some embodiments, the pressure relief space 1001 , such as the second pressure relief groove 1181 , can enable the electrical connector 104 to have a waterproof rating of IPX8 when no glue dispensing process is performed.

[0096] See also Figure 3 , Figure 4 and Fig. 9 , Fig. 9 yes Figure 4 An exploded view of the housing 30 in the illustrated embodiment. The housing 30 can be used to install components required for the electrical connector 104, and the housing 30 can also be connected to the circuit board 103 to fix the electrical connector 104 on the circuit board 103, thereby preventing the electrical connector 104 and the circuit board 103 from moving relative to each other, resulting in poor contact between the electrical connector 104 and the circuit board 103.

[0097] The housing 30 may be a metal housing, for example, but not limited to, a housing made of aluminum, aluminum alloy, etc., and of course, a hard housing made of other materials. The housing 30 may include an inner housing 31 for forming a plug-in space 3001 and fixedly connected to the docking tongue plate 10, and an outer housing 32 connected to the circuit board 103 and sleeved around the inner housing 31. The inner housing 31 and the outer housing 32 are fixedly connected.

[0098] The side wall of the inner shell 31 can be barrel-shaped to form a plug-in space 3001. The plug-in space 3001 in the inner shell 31 can be used to accommodate the docking tongue plate 10. The plug-in space 3001 can be connected to the through slot 1013, so that the connection wire, such as the connector, can pass through the through slot 1013 during the plug-in operation to enter the plug-in space 3001 and connect with the connection terminal 20 on the docking tongue plate 10. In addition, the shape of the plug-in space 3001 can be adapted to the shape of the connection wire, such as the connector, so as to facilitate the connection between the electrical connector 104 and the connection wire, such as the connector.

[0099] In some embodiments, a partial area of ​​the inner shell 31 can be disposed in the through groove 1013, so that a sealing ring can be disposed between the side wall of the inner shell 31 and the inner wall of the through groove 1013 to improve the sealing of the electronic device 100.

[0100] In some embodiments, the inner shell 31 may be sealed and connected to the waterproof glue block 13. In some embodiments, waterproofing may be achieved by applying waterproof glue on the side of the base 14 away from the extension 15 so that the waterproof glue solidifies and blocks the gap between the inner shell 31 and the base 14.

[0101] The outer shell 32 can be disposed around the inner shell 31 and respectively connected to the circuit board 103 and the inner shell 31 to limit the inner shell 31 and prevent the inner shell 31 and the circuit board 103 from making relative movement, resulting in poor contact between the electrical connector 104 and the circuit board 103 .

[0102] The outer shell 32 may include a first cover 321 and a second cover 322 that are snap-fitted. Partial areas of the first cover 321 and the second cover 322 may be stacked. The first cover 321 and the second cover 322 may be fixed together by welding. At the same time, the first cover 321 and the second cover 322 may also be surrounded to form a limiting space 3002 to accommodate the inner shell 31 through the limiting space 3002, so that the inner shell 31 can be clamped in the middle by the first cover 321 and the second cover 322, thereby realizing the limiting of the inner shell 31 by the outer shell 32.

[0103] In some embodiments, the first cover 321 and the second cover 322 may be connected to the outer surface of the inner shell 31 by welding to improve the connection firmness between the outer shell 32 and the inner shell 31. At the same time, the outer shell 32 may also be connected to the circuit board 103.

[0104] In some embodiments, a portion of the first cover 321 may extend toward the second cover 322 to form a connecting arm 3211. The connecting arm 3211 may be connected to the circuit board 103 to achieve connection between the outer shell 32 and the circuit board 103, so that the inner shell 31 may be fixed to the circuit board 103 through the outer shell 32.
