Technical Field

[0001] The present application relates to the field of electronic product accessories, and in particular to a female socket interface, a male socket and an electronic device. Background Art

[0002] With the development of technology, portable electronic devices such as mobile phones and tablets have become necessities of life. These electronic devices generally consume a lot of power and need to be frequently charged to ensure the normal use of the product. Currently, the more commonly used charging ports on the market include Type-C interface, Lighting interface, Micro-USB interface, etc., among which Type-C interface is the most widely used.

[0003] The existing Type-C interface includes 24 pins. In order to facilitate mass production, the size of the Type-C interface usually needs to meet the design requirements of the standard interface, that is, the size of the Type-C interface is certain. If the pin setting is unreasonable, and the Type-C interface is in an open state when used in electronic devices, liquid is likely to enter the interface, which may cause a short circuit between the power pins and the risk of burning. Summary of the invention

[0004] The embodiments of the present application provide a female socket interface, a male socket and an electronic device, which can effectively reduce the risk of short circuit and burning of the female socket interface.

[0005] In a first aspect, an embodiment of the present application provides a female socket interface for connecting to a male socket, the female socket interface comprising:

[0006] An annular shell is formed with a receiving cavity;

[0007] A tongue plate, disposed in the accommodating cavity, the tongue plate comprising a first connecting surface; and

[0008] The first pin group includes a first positive pin, a first ground pin and multiple first signal pins. The first positive pin, multiple first signal pins and the first ground pin are arranged on the first connecting surface at intervals along the width direction of the tongue plate, and the minimum spacing between the first positive pin and the first ground pin is greater than the minimum spacing between adjacent first signal pins among the multiple first signal pins.

The third positive pin, multiple third signal pins and the third ground pin are arranged on the first inner wall at intervals along the width direction of the first inner wall, and the minimum spacing between the third positive pin and the third ground pin is greater than the minimum spacing between adjacent third signal pins among the multiple third signal pins.

[0013] The embodiments of the present application provide a female socket interface, a male socket and an electronic device, by configuring a first pin group arranged on one side of the tongue plate of the female socket interface to include a first positive pin, a first ground pin and a plurality of first signal pins, that is, there is only one first positive pin and only one first ground pin on the first connecting surface of the tongue plate. Compared with the related art in which two positive pins and two ground pins are arranged on one side of the tongue plate, the number of pins on one side of the tongue plate is reduced in the present application, so that more space can be freed up on the tongue plate. In this way, by utilizing the extra space, it can be ensured that the first positive pin and the first ground pin can be spaced sufficiently apart, that is, the spacing between the first positive pin and the first ground pin can be increased, thereby effectively reducing the probability of a short circuit between the first positive pin and the first ground pin after liquid enters the female socket interface, and reducing the risk of corrosion and burning. In addition, the minimum spacing between the first positive electrode pin and the first grounding pin is greater than the minimum spacing between adjacent first signal pins among the plurality of first signal pins, that is, the spacing between the first positive electrode pin and the first grounding pin can be made as large as possible to reduce the probability of short circuit between the first positive electrode pin and the first grounding pin after the female socket interface is filled with liquid, and reduce the risk of corrosion and burning. And by utilizing the extra space, the width of the first positive electrode pin and the width of the first grounding pin can be made as large as possible, so that the width of the first positive electrode pin and the width of the first grounding pin can be effectively increased to improve the overcurrent capacity of the first positive electrode pin and the first grounding pin, and provide support for high-power charging.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0024] The embodiment of the present application provides a female socket interface, a male socket and an electronic device, which can effectively reduce the risk of short circuit and burnout of the female socket interface. This will be described below with reference to the accompanying drawings.

The following description will take a mobile phone as an example. Figure 1 As shown, the electronic device 100 may include a housing 10 and a display component 20. The display component 20 is disposed on the housing 10 and may be used to display images.

[0027] It can be understood that the electronic device 100 also includes a female socket interface 30, a circuit board 40 and a battery 50, the circuit board 40 and the battery 50 are both arranged in the housing 10, and the battery 50 and the display assembly 20 are respectively electrically connected to the circuit board 40. The female socket interface 30 is arranged in the housing 10, and the female socket interface 30 is electrically connected to the circuit board 40. Among them, the female socket interface 30 can be used to transmit data and to charge the battery 50 of the electronic device 100, such as, the female socket interface 30 can be connected to the male socket adapted thereto to realize the function of transmitting data or charging.

[0028] See also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of the female socket interface provided in the embodiment of the present application. Figure 3 for Figure 2 The schematic diagram of the structure of the annular shell of the female socket interface is shown. The female socket interface 30 may include an annular shell 31 and a tongue plate 32, the annular shell 31 is formed with a receiving cavity 311, and the tongue plate 32 is arranged in the receiving cavity 311. It can be understood that the tongue plate 32 is provided with pins, and when the male socket is plugged into the receiving cavity 311 of the annular shell 31, the pins on the male socket can contact the pins on the tongue plate 32, thereby realizing the electrical connection between the male socket pins and the tongue plate 32 pins, so as to realize the function of transmitting data or charging.

[0029] Exemplarily, the annular shell 31 forms a substantially cylindrical structure, and the longitudinal interface of the area surrounded by the annular shell 31 is substantially oblong (waist-shaped), the annular shell 31 forms a receiving cavity 311, and the tongue plate 32 is disposed in the receiving cavity 311. Figure 3 As shown, the accommodating cavity 311 has an insertion port 312 for inserting the male socket. The male socket can extend into the accommodating cavity 311 through the insertion port 312 to be electrically connected to the pins on the tongue plate 32.

[0030] Please continue to refer to 3 , the annular shell 31 may include a shell body 313 and a plurality of plug pins 314 , the shell body 313 is used to form a receiving cavity 311 , and the plug pins 314 are connected to the shell body 313 to fix the shell body 313 to the housing 10 of the electronic device 100 .

[0031] The shell body 313 includes a first wall 3131 and a second wall 3132, and a third wall 3133 and a fourth wall 3134. The third wall 3133 and the fourth wall 3134 are connected between the first wall 3131 and the second wall 3132. The first wall 3131, the second wall 3132, the third wall 3133 and the fourth wall 3134 form a receiving cavity 311. The first wall 3131 and the second wall 3132 are generally planar plate structures, and the third wall 3133 and the fourth wall 3134 are generally arc structures. The shell body 313 is a flat structure as a whole, and the area of ​​the first wall 3131 and the second wall 3132 is greater than the area of ​​the third wall 3133 and the fourth wall 3134.

[0032] The plug pin 314 is connected to one end of the shell body 313 away from the insertion port 312 and extends in a direction away from the shell body 313 . The plug pin 314 may be integrated with the shell body 313 or welded to the shell body 313 .

[0033] It should be noted that the shell body 313 and the plug pins 314 can be made of metal materials or alloys, for example, the shell body 313 and the plug pins 314 can be made of iron, aluminum, etc. In some other embodiments, the shell body 313 and the plug pins 314 can also be made of high-strength resin plastics, etc., which is not specifically limited here.

[0034] It should also be noted that, in some embodiments, the female socket interface 30 may not include an independently arranged annular shell 31. It can be understood that, in this case, a through hole can be set at the position on the outer shell 10 for setting the female socket interface 30, so that the annular shell 31 is formed locally on the outer shell 10.

[0035] The circuit board 40 can be used to control the display component 20 for display, and control the female socket interface 30 for data transmission and charging.

[0036] Exemplarily, the housing 10 of the electronic device 100 includes a bottom plate (not shown) and a side plate (not shown) bent and connected to the bottom plate. The bottom plate and the side plate enclose a receiving space, in which the circuit board 40 and the battery 50 are arranged, and the female socket interface 30 is located on the side plate. In some embodiments, the bottom plate and the side plate are an integral structure, and in other embodiments, the bottom plate and the side plate are formed separately and then connected together. In a specific embodiment, the bottom plate can be the back cover of the electronic device 100, and the side plate is the middle frame of the electronic device 100.

[0037] It can be understood that the display component 20 can be, but is not limited to, one or more of a liquid crystal display component, a light emitting diode display component (LED display component), a micro light emitting diode display component (MicroLED display component), a sub-millimeter light emitting diode display component (MiniLED display component), an organic light emitting diode display component (OLED display component), etc.

[0038] Exemplarily, the circuit board 40 may include a processor and a memory. The processor is electrically connected to the display assembly 20, the female socket interface 30 and the memory respectively. The processor is used to control the display assembly 20 for display, and control the female socket interface 30 for data transmission or charging; the memory is used to store the program code required for the processor to run, the program code required to control the display assembly 20, the display content of the display assembly 20, the program code for controlling the female socket interface 30 for data transmission and charging, etc.

[0039] Optionally, the processor includes one or more general-purpose processors, wherein the general-purpose processor can be any type of device capable of processing electronic instructions, including a central processing unit (CPU), a microprocessor, a microcontroller, a main processor, a controller, and an ASIC, etc. The processor is used to execute various types of digital storage instructions, such as software or firmware programs stored in a memory, which enables the computing device to provide a wide variety of services.

[0040] Optionally, the memory may include a volatile memory (Volatile Memory), such as a random access memory (RAM); the memory may also include a non-volatile memory (NVM), such as a read-only memory (ROM), a flash memory (FM), a hard disk drive (HDD), or a solid-state drive (SSD). The memory may also include a combination of the above-mentioned types of memory.

[0041] It should be noted that the female socket interface 30 is a component that docks with the male socket. Exemplarily, the female socket interface 30 can be a Type-C interface. It can be understood that in related technologies, the Type-C interface usually adopts a 16-pin structure or a 24-pin structure, wherein the 16-pin structure means that the female socket interface includes 16 pins, wherein the 16 pins are symmetrically distributed on the two surfaces of the tongue plate in the female socket interface, that is, 8 pins are arranged on each side surface of the tongue plate.

[0042] The 24-pin structure means that the female socket interface includes 24 pins, wherein the 24 pins are symmetrically distributed on the two surfaces of the tongue plate in the female socket interface, that is, 12 pins are arranged on each side surface of the tongue plate.

[0043] Whether it is a 16-pin structure or a 24-pin structure, the pins include a positive pin and a ground pin for charging, and also include a signal pin for transmitting data, wherein a positive pin, a signal pin, and a ground pin are distributed on each surface of the tongue. In the related art, whether it is a 16-pin structure or a 24-pin structure, two positive pins and two ground pins are distributed on each surface of the tongue. Since the size of the Type-C interface usually needs to meet the design requirements of the standard interface, that is, the size of the Type-C interface is certain, in the related art, due to the large number of pins, if the pins are set unreasonably, and when the Type-C interface is applied to electronic devices, since the Type-C interface is in an open state, it is easy to have liquid ingress, which easily causes the risk of short circuit and burnout between the power pins (positive pin and ground pin).

[0044] Based on this, see Figure 4 and Figure 5 Combined with Figure 2 and Figure 3 , Figure 4 for Figure 2 Schematic diagram of the structure of the middle tongue plate and the first pin group, Figure 5 for Figure 2 Schematic diagram of the structure of the tongue plate and the second pin group. The female socket interface 30 provided in the embodiment of the present application may include a first pin group 33 and a second pin group 34. It can be understood that the tongue plate 32 includes a first connection surface 321 and a second connection surface 322 arranged opposite to each other, and the first connection surface 321 and the second connection surface 322 are located on opposite sides of the thickness direction of the tongue plate 32. Among them, the first connection surface 321 faces the first wall 3131 of the annular shell 31, and the second connection surface 322 faces the second wall 3132 of the annular shell 31. The first connection surface 321 and the second connection surface 322 can be roughly parallel to each other, and the first connection surface 321 can be roughly parallel to the first wall 3131, and the second connection surface 322 can be roughly parallel to the second wall 3132. The first pin group 33 is arranged on the first connection surface 321, and the second pin group 34 is arranged on the second connection surface 322. It can be understood that the first pin group 33 and the second pin group 34 are symmetrically arranged. The first pin group 33 and the second pin group 34 are respectively electrically connected to the circuit board 40 of the electronic device 100. The first pin group 33 and the second pin group 34 are used to be electrically connected to the male socket to achieve the function of transmitting data or charging.

[0045] It is understandable that the tongue plate 32 can be formed by plastic injection molding, the first pin group 33 and the second pin group 34 can be set on the first connection surface 321 and the second connection surface 322 by embedding, and the first pin group 33 and the second pin group 34 are at least partially exposed, so that the male socket can be electrically connected with the first pin group 33 and the second pin group 34 when inserted into the insertion hole. Exemplarily, the first pin group 33 and the second pin group 34 can be combined with the tongue plate 32 by integral injection molding.

[0046] Among them, see Figure 4 The first pin group 33 includes a first positive pin 331, a first ground pin 332 and multiple first signal pins 333. The first positive pin 331, multiple first signal pins 333 and the first ground pin 332 are arranged on the first connecting surface 321 at intervals along the width direction of the tongue plate 32. The minimum spacing between the first positive pin 331 and the first ground pin 332 is greater than the minimum spacing between adjacent first signal pins 333 among the multiple first signal pins 333.

[0047] By setting the first pin group 33 arranged on one side of the tongue plate 32 of the female socket interface 30 to include a first positive pin 331, a first ground pin 332 and a plurality of first signal pins 333, that is, there is only one first positive pin 331 and only one first ground pin 332 on the first connecting surface 321 of the tongue plate 32, compared with the related art in which two positive pins and two ground pins are set on one side of the tongue plate, the number of pins on one side of the tongue plate 32 is reduced in the present application, so that more space can be freed up on the tongue plate 32. In this way, by utilizing the extra space, it can be ensured that the first positive pin 331 and the first ground pin 332 can be spaced sufficiently apart, that is, the spacing between the first positive pin 331 and the first ground pin 332 can be increased, thereby effectively reducing the probability of a short circuit between the first positive pin 331 and the first ground pin 332 after the female socket interface 30 is filled with liquid, thereby reducing the risk of corrosion and burning. In addition, the minimum spacing between the first positive pin 331 and the first ground pin 332 is greater than the minimum spacing between adjacent first signal pins 333 among the plurality of first signal pins 333, that is, the spacing between the first positive pin 331 and the first ground pin 332 can be made as large as possible to reduce the probability of short circuit between the first positive pin 331 and the first ground pin 332 after the female socket interface 30 is filled with liquid, and reduce the risk of corrosion and burning. And by utilizing the extra space, the width of the first positive pin 331 and the width of the first ground pin 332 can be made as large as possible, so that the width of the first positive pin 331 and the width of the first ground pin 332 can be effectively increased to improve the overcurrent capacity of the first positive pin 331 and the first ground pin 332, and provide support for high-power charging.

[0048] It can be understood that the number of pins in the second pin group 34 is the same as the number of pins in the first pin group 33, the spacing between the pins in the second pin group 34 is the same as the spacing between the corresponding pins in the first pin group 33, and the width and structure of the pins are also the same. Figure 5 The second pin group 34 includes a second positive pin 341, a second ground pin 342 and multiple second signal pins 343. The second positive pin 341, multiple second signal pins 343 and the second ground pin 342 are arranged on the second connecting surface 322 at intervals along the width direction of the tongue plate 32. The minimum spacing between the second positive pin 341 and the second ground pin 342 is greater than the minimum spacing between adjacent second signal pins 343 among the multiple second signal pins 343.

[0049] It can also be understood that the structure of the second positive pin 341 is the same as that of the first positive pin 331, the structure of the second ground pin 342 is the same as that of the first ground pin 332, and the number and structure of the second signal pin 343 are also the same as the number and structure of the first signal pin 333.

[0050] Exemplarily, the plurality of first signal pins 333 of the present application may include 4 first signal transmission pins or 8 first signal transmission pins. That is, when the plurality of first signal pins 333 include 4 first signal transmission pins, the second signal pins 343 also include 4 second signal transmission pins. When the plurality of first signal pins 333 include 4 first signal transmission pins, the second signal pins 343 also include 4 second signal transmission pins.

[0051] It should be noted that, in a conventional 16-pin female socket interface, one side of its tongue plate includes 2 positive pins, 2 ground pins and 4 signal transmission pins, and in the present application, when the multiple first signal pins 333 include 4 first signal transmission pins, that is, the transmission capacity of the female socket interface 30 of the present application (at this time the female socket interface 30 can be called a 12-pin female socket interface) is roughly the same as that of the conventional 16-pin female socket interface. It can be understood that the size of the 16-pin female socket interface usually needs to meet the design requirements of the standard interface, that is, the size of the female socket interface 30 is certain, or the size of the tongue plate 32 is certain, because the first positive pins on the first connecting surface 321 of the tongue plate 32 of the present application There is only one positive pin 331 and one first ground pin 332. Compared with the 16-pin female socket interface in the related art, which has two positive pins and two ground pins on one side of the tongue plate, the number of pins on one side of the tongue plate 32 is reduced in the present application, so that more space can be freed up on the tongue plate 32. In this way, by utilizing the extra space, it can be ensured that the first positive pin 331 and the first ground pin 332 can be spaced sufficiently apart, that is, the spacing between the first positive pin 331 and the first ground pin 332 can be increased, thereby effectively reducing the probability of a short circuit between the first positive pin 331 and the first ground pin 332 after the female socket interface 30 is filled with liquid, thereby reducing the risk of corrosion and burning. And by utilizing the extra space, the width of the first positive pin 331 and the width of the first ground pin 332 can be made as large as possible. In this way, the width of the first positive pin 331 and the width of the first ground pin 332 can be effectively increased to improve the current capacity of the first positive pin 331 and the first ground pin 332, thereby providing support for high-power charging.

[0052] It can be understood that when the multiple first signal pins 333 include four first signal transmission pins, the four first signal transmission pins can be respectively: a configuration channel signal pin (Configuration channel, CC1 pin), a first differential signal pin (Dp1 pin, USB2.0 differential signal, positive), a second differential signal pin (Dn1 pin, USB2.0 differential signal, negative) and an auxiliary signal pin (SBU1 pin). Among them, the configuration channel signal (CC1 pin) is used for device discovery, configuration and management. Exemplarily, the configuration channel signal (CC1 pin) can be used to detect positive and reverse insertion. SBU1 is an auxiliary signal and has different uses in different application scenarios. For example, when DP signal transmission is performed in ALT MODE mode, the auxiliary signal pin (SBU1 pin) can be used as an audio transmission channel. When entering the TYPE-C analog audio headset accessory mode, the auxiliary signal pin (SBU1 pin) is used as a microphone signal transmission channel.

[0053] It should also be noted that, in a conventional 24-pin female socket interface, one side of its tongue plate includes 2 positive pins, 2 ground pins and 8 signal transmission pins, and in the present application, when the multiple first signal pins 333 include 8 first signal transmission pins, that is, the transmission capacity of the female socket interface 30 of the present application (at this time, the female socket interface 30 can be called a 20-pin female socket interface) is roughly the same as that of the conventional 24-pin female socket interface. It can be understood that the size of the 24-pin female socket interface usually needs to meet the design requirements of the standard interface, that is, the size of the female socket interface 30 is certain, or the size of the tongue plate 32 is certain, because the first connection surface 321 on the tongue plate 32 of the present application There is only one positive pin 331 and only one first ground pin 332. Compared with the 24-pin female socket interface in the related art, which has two positive pins and two ground pins on one side of the tongue plate, the number of pins on one side of the tongue plate 32 is reduced in the present application, so that more space can be freed up on the tongue plate 32. In this way, by utilizing the extra space, it can be ensured that the first positive pin 331 and the first ground pin 332 can be spaced sufficiently apart, that is, the spacing between the first positive pin 331 and the first ground pin 332 can be increased, thereby effectively reducing the probability of a short circuit between the first positive pin 331 and the first ground pin 332 after the female socket interface 30 is filled with liquid, thereby reducing the risk of corrosion and burning. And by utilizing the extra space, the width of the first positive pin 331 and the width of the first ground pin 332 can be made as large as possible. In this way, the width of the first positive pin 331 and the width of the first ground pin 332 can be effectively increased to improve the current capacity of the first positive pin 331 and the first ground pin 332, thereby providing support for high-power charging.

[0054] It can be understood that when the plurality of first signal pins 333 include 8 first signal transmission pins, the 8 first signal transmission pins can be respectively: a first high-speed transmission signal pin (SSTXp1 pin, SuperSpeed ​​differential signal 1, positive), a second high-speed transmission signal pin (SSTXn1 pin, SuperSpeed ​​differential signal 1, negative), a configuration channel signal pin (Configuration channel, CC1 pin), a first differential signal pin (Dp1 pin, USB2.0 differential signal, positive), a second differential signal pin (Dn1 pin, USB2.0 differential signal, negative), an auxiliary signal pin (SBU1 pin), a third high-speed transmission signal pin (SSTXn2 pin, SuperSpeed ​​differential signal 2, negative) and a fourth high-speed transmission signal pin (SSTXp2 pin, SuperSpeed ​​differential signal 2, positive). Among them, the configuration channel signal (CC1 pin) is used for device discovery, configuration and management. Exemplarily, the configuration channel signal (CC1 pin) can be used to detect forward and reverse insertion. SBU1 is an auxiliary signal and has different uses in different application scenarios. For example, when DP signal is transmitted in ALT MODE mode, the auxiliary signal pin (SBU1 pin) can be used as an audio transmission channel. When entering the TYPE-C analog audio headset accessory mode, the auxiliary signal pin (SBU1 pin) is used as a microphone signal transmission channel.

[0055] Taking the structure of the present application applied to a conventional 24-pin female socket interface as an example, it can be understood that the size of the tongue plate 32 is certain, such as the width of the portion of the tongue plate 32 used to receive the pin is 6.69 mm ± 0.1 mm. Since the center distance between the pins on one side of the tongue plate 32 is certain, such as the center distance between the pins is usually 0.5 mm, the minimum spacing between the pins is related to the width of the pins. The larger the width of the pin, the smaller the spacing between the pins. If the spacing is too small, it is easy to cause a short circuit between the pins. The existing 24-pin Type C is composed of 4 positive pins (VBUS pins), 4 ground pins (GND pins) and 16 signal pins, that is, one side of the tongue includes 2 positive pins (VBUS pins), 2 ground pins (GND pins) and 8 signal pins. The width of the VBUS pin and the GND pin are both 0.30 mm, and the distance between the VBUS pin and the GND pin is only 1.2 mm. When liquid enters, it is easy to cause a short circuit between the VBUS pin and the GND pin, resulting in electrochemical corrosion. The surface of the pin will be electrolyzed or corroded, and the surface contact impedance will change, which will cause charging abnormalities.

[0056] In this application, please refer to Figure 4In the present application, the first pin group 33 located on one side of the tongue plate 32 is arranged to include a first positive pin 331, a first ground pin 332 and a plurality of first signal pins 333, that is, there is only one first positive pin 331 (first VBUS pin) and only one first ground pin 332 (first GND pin) on the first connection surface 321 of the tongue plate 32. Compared with the related art in which two positive pins and two ground pins are arranged on one side of the tongue plate, the number of pins on one side of the tongue plate 32 is reduced in the present application, so that more space can be freed up on the tongue plate 32. In this way, by utilizing the extra space, it can be ensured that the first positive pin 331 and the first ground pin 332 can be spaced sufficiently large, that is, the spacing between the first positive pin 331 and the first ground pin 332 can be increased, thereby effectively reducing the probability of a short circuit between the first positive pin 331 and the first ground pin 332 after the female socket interface 30 is filled with liquid, thereby reducing the risk of corrosion and burning.

[0057] Exemplarily, the minimum spacing D between the first positive pin 331 and the first ground pin 332 is set in the range of 1.61 mm to 1.75 mm. In this way, the minimum spacing between the first positive pin 331 and the first ground pin 332 is greatly increased, thereby effectively reducing the probability of short circuit between the first positive pin 331 and the first ground pin 332 after the female socket interface 30 is filled with liquid, and reducing the risk of corrosion and burns. For example, the minimum spacing D between the first positive pin 331 and the first ground pin 332 can be 1.61 mm, 16.2 mm, 1.65 mm, 1.71 mm, 1.73 mm or 1.75 mm.

[0058] In order to fully utilize the space on the tongue plate 32 and make the minimum distance between the first positive pin 331 and the first ground pin 332 as large as possible, please refer to Figure 4 , at least one first signal pin 333 may be provided between the first positive pin 331 and the first ground pin 332. In this way, the space between the first positive pin 331 and the first ground pin 332 can be utilized so that the minimum spacing between the first positive pin 331 and the first ground pin 332 can be made larger. Exemplarily, one first signal pin 333, two first signal pins 333, three first signal pins 333, four first signal pins 333 or five first signal pins 333 may be provided between the first positive pin 331 and the first ground pin 332, and the present application does not make any limitation thereto. Figure 4 As shown in , three first signal pins 333 may be disposed between the first positive pin 331 and the first ground pin 332 .

[0059] In order to improve the overcurrent capacity of the first positive pin 331 and the first ground pin 332, the maximum width of the first positive pin 331 is three times the maximum width of the first signal pin 333, and the maximum width of the first ground pin 332 is three times the maximum width of the first signal pin 333. In this way, the width of the first positive pin 331 and the width of the first ground pin 332 can be effectively increased to improve the overcurrent capacity of the first positive pin 331 and the first ground pin 332, and provide support for high-power charging.

[0060] It can also be understood that by utilizing the extra space on the tongue plate 32, the width of the first positive pin 331 and the width of the first ground pin 332 can be made as large as possible. Exemplarily, the maximum width of the first positive pin 331 and the maximum width of the first ground pin 332 range from 0.6 mm to 0.82 mm, wherein the maximum width of the first signal pin 333 ranges from 0.21 mm to 0.29 mm. By setting the maximum width of the first positive pin 331 and the maximum width of the first ground pin 332 to range from 0.6 mm to 0.82 mm, compared to the VBUS pin and the GND pin in the related art, which are both 0.30 mm wide, the widths of the first positive pin 331 and the first ground pin 332 of the present application are greatly increased, thereby effectively improving the overcurrent capacity of the first positive pin 331 and the first ground pin 332, and providing support for high-power charging, such as the first positive pin 331 and the first ground pin 332 of the present application can carry a current of 15A. Exemplarily, the maximum width of the first positive pin 331 and the maximum width of the first ground pin 332 may both be 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, or 0.82 mm.

[0061] In some embodiments, see Figure 4 The tongue plate 32 includes a first side wall 323 and a second side wall 324, which are arranged opposite to each other in the width direction of the tongue plate 32. The first side wall 323 is provided with a first buckle piece 35 protruding from the first side wall 323, and the second side wall 324 is provided with a second buckle piece 36 protruding from the second side wall 324, wherein the first buckle piece 35 and the second buckle piece 36 can be used for buckling with the male seat, and by providing the first buckle piece 35 and the second buckle piece 36, the docking stability between the female seat interface 30 and the male seat can be improved. The first buckle piece 35 and the second buckle piece 36 are made of metal materials, such as stainless steel, so that the wear resistance of the first buckle piece 35 and the second buckle piece 36 can be improved.

[0062] Since the first buckle tab 35 and the second buckle tab 36 made of metal are conductive, in order to prevent the first positive pin 331 from being short-circuited with the first buckle tab 35 and the second buckle tab 36 on both sides, in the present application, Figure 4 As shown, the first positive pin 331 is spaced apart from the side edge of the tongue plate 32 in the width direction by at least the first ground pin 332 or the first signal pin 333, or in other words, the first positive pin 331 is not disposed at the edge of the tongue plate 32, so that the first positive pin 331 can be effectively prevented from being short-circuited with the first buckle piece 35 or the second buckle piece 36. Exemplarily, the first positive pin 331 can be disposed approximately in the middle of the tongue plate 32.

[0063] On the other hand, see Figure 6 , Figure 6 A schematic diagram of the structure of the connecting wire provided in the embodiment of the present application.

The connector 230 is used to connect to an external power source, such as a household power supply (220V), or to connect to other electronic devices 100, such as a USB port on a computer, a power bank, or a power adapter. The connector 230 can be configured in a variety of forms, such as a USB connector, a Micro USB connector, a Type-C connector, etc. The connector 230 can also be directly configured as an adapter structure, which is not limited here. The wire 220 can be set to any length and covered with an outer sheath made of a plastic insulating member.

[0064] The male socket 210 can be adapted to the aforementioned female socket interface 30, and the male socket 210 can be inserted into the accommodating cavity 311 of the annular shell 31 of the female socket interface 30, so that the pins on the male socket 210 can contact the first pin group 33 and the second pin group 34 of the female socket interface 30 to realize the function of transmitting data or charging.

[0065] See also Figure 7 Combined with Figure 2 , Figure 7The cross-sectional view of the male socket provided in the embodiment of the present application. The male socket 210 includes a plug shell 211 and a third pin group 212 and a fourth pin group 213 arranged on the inner wall of the plug shell 211, wherein the structure of the plug shell 211 is adapted to the structure of the annular shell 31 of the female socket interface 30, so that the plug shell 211 can extend into the accommodating cavity 311 surrounded by the annular shell 31 through the insertion port 312 of the annular shell 31, and when the plug shell 211 extends into the accommodating cavity 311, there can be interference between the plug shell 211 and the annular shell 31, so that the male socket 210 can be relatively fixed with the female socket interface 30. The plug-in shell 211 forms an inner cavity 2111. When the plug-in shell 211 is inserted into the female socket interface 30, the tongue plate 32 of the female socket interface 30 is inserted into the inner cavity 2111 of the plug-in shell 211, wherein the plug-in shell 211 includes a first inner wall 2112 and a second inner wall 2113 relative to each other, the third pin group 212 is arranged on the first inner wall 2112, and the fourth pin group 213 is arranged on the second inner wall 2113. When the male socket 210 is docked with the female socket interface 30, the third pin group 212 is electrically connected to the first pin group 33, and the fourth pin group 213 is electrically connected to the second pin group 34.

[0066] The third pin group 212 and the fourth pin group 213 can both be electrically connected to the wire 220 to receive external power feeding. The third pin group 212 includes a third positive pin 2121, a third ground pin 2122 and a plurality of third signal pins 2123. The third positive pin 2121, the plurality of third signal pins 2123 and the third ground pin 2122 are arranged on the first inner wall 2112 at intervals along the width direction of the first inner wall 2112.
