Technical Field

[0001] The present application relates to the technical field of USB connectors, and in particular to an electronic device and a USB connector. Background Art

[0002] The circuit board in the electronic device is usually connected to the external device through a USB (Universal Ser ia l Bus, USB) connector for data transmission. Generally speaking, the USB connector is connected to the circuit board through a cable, which easily makes the cables in the device complicated and occupies volume. Therefore, how to design an electronic device with a USB connector that can be connected reliably and without cables is a problem that needs to be solved. Utility Model Content

[0003] Embodiments of the present application provide an electronic device and a USB connector capable of improving reliability.

[0004] In a first aspect, an embodiment of the present application provides an electronic device, including a housing, a circuit board and a USB connector, wherein the circuit board is accommodated in the housing; and the housing is provided with a through hole. The USB connector includes a first insulating shell, a second insulating shell, and an electrical connection body. The first insulating shell and the second insulating shell are slidably connected along the axial direction of the USB connector. The second insulating shell is penetrated in the through hole. The electrical connection body is penetrated in the first insulating shell and the second insulating shell, and one end of the electrical connection body is electrically connected to the circuit board.

[0005] The electronic device provided by the present application directly connects the electrical connection body to the circuit board, which can eliminate the cable between the circuit board and the USB connector. At the same time, in the axial direction of the USB connector, since the second insulating shell is connected to the first insulating shell by sliding along the axial direction of the USB connector, the first insulating shell and the second insulating shell are not locked and fixed with each other. In this way, during assembly or use, the second insulating shell can move or float relative to the first insulating shell in the axial direction of the USB connector, so that the USB connector can adapt to different distances between the shell and the circuit board to absorb the assembly tolerance between the USB connector and the shell, and can absorb the stress between the circuit board and the USB connector, which is conducive to reducing the risk of failure of the electrical connection between the electrical connection body and the circuit board, thereby solving the problem of cable-free connection and providing a reliable USB connector.

[0006] In addition, the USB connector adopts a floating design. When the USB connector is installed on the housing and the circuit board, the circuit board does not need to be provided with an on-board USB connector, and the internal part of the device or apparatus equipped with the USB connector does not need to add additional internal USB connector interfaces and wiring harnesses. In this way, the number of components is reduced, the connection structure between the circuit board and the USB connector is simplified, and the reliability of the electrical connection between the USB connector and the circuit board is reduced.

[0007] According to the first aspect, in a possible implementation, one end of the first insulating shell is accommodated in the second insulating shell, and the inner circumferential wall of the second insulating shell is provided with a first stop structure, and the first stop structure is used to abut against the first insulating shell in the axial direction of the USB connector.

[0008] According to the first aspect, in a possible implementation, one end of the first insulating shell is accommodated in the second insulating shell, and the inner circumferential wall of the second insulating shell is provided with a first stop structure, and the first stop structure is used to abut against the first insulating shell in the axial direction of the USB connector.

[0009] In this possible implementation, the first stop structure is used to abut against the first insulating shell in the axial direction to limit the movement stroke of the first insulating shell relative to the second insulating shell.

[0010] According to the first aspect, in a possible implementation, the inner circumferential wall of the second insulating shell is provided with a slide groove, the first stop structure is located at the axial end wall of the slide groove in the USB connector, and the outer circumferential wall of the first insulating shell is provided with a protrusion, which is accommodated in the slide groove, and the protrusion can be abutted against the first stop structure in the axial direction of the USB connector.

[0011] In this possible implementation, since the first stop structure is arranged on the end wall of the slide slot, that is, the end wall of the reused slide slot is used as the stop structure, the structure of the first insulating shell is simplified. The protrusion is accommodated in the slide slot, and the slide slot can guide the movement of the second insulating shell relative to the first insulating shell, thereby improving the smoothness of the movement of the second insulating shell relative to the first insulating shell.

[0012] According to the first aspect, in this possible implementation, the inner circumferential wall of the second insulating shell is also provided with a second stop structure, and the second stop structure is used to axially abut against the first insulating shell. In the axial direction of the USB connector, the distance between the first stop structure and the circuit board is greater than the distance between the second stop structure and the circuit board.

[0013] In this possible implementation, the first stop structure is used to limit the movement stroke of the second insulating shell away from the circuit board, and the second stop structure is used to limit the movement stroke of the second insulating shell toward the circuit board. In this way, the movement stroke of the first insulating shell relative to the second insulating shell toward or away from the circuit board is restricted.

[0014] According to the first aspect, in this possible implementation, one end of the second stop structure is a free end extending toward the circuit board, and the free end includes a hook protruding toward the inner cavity of the second insulating shell, and the hook is used to abut against the end face of the first insulating shell axially facing the circuit board of the USB connector.

[0015] In this possible implementation, one end of the second stop structure is a free end to increase the deformation ability of the second stop structure and facilitate the first insulating shell to penetrate the second insulating shell. The second stop structure stops the end surface of the first insulating shell through the hook, which is conducive to improving the stopping effect and has a simple structure.

[0016] According to the first aspect, in this possible implementation, the second insulating shell is provided with a plug-in protrusion on one axial end face of the USB connector, the circuit board is provided with a plug-in hole, and the plug-in protrusion is inserted into the plug-in hole.

[0017] In this possible implementation, the plug-in hole and the plug-in protrusion can position the assembly between the circuit board and the second insulating shell, which is beneficial to improving the assembly accuracy and efficiency between the USB connector and the circuit board.

[0018] According to the first aspect, in this possible implementation, the USB connector also includes a first seal, which is sleeved on the first insulating shell. In the radial direction of the first insulating shell, the first seal is sealed and connected between the outer circumferential wall of the first insulating shell and the inner circumferential wall of the second insulating shell.

[0019] In this possible implementation, in the radial direction of the first insulating shell, the first sealing member is sealed and connected between the outer circumferential wall of the first insulating shell and the inner circumferential wall of the second insulating shell. In this way, the sealing performance between the first insulating shell and the second insulating shell is improved, and the possibility of water vapor entering the interior of the electronic device through the gap between the outer circumferential wall of the first insulating shell and the inner circumferential wall of the second insulating shell is reduced, thereby improving the reliability of the USB connector and the electronic device.

[0020] According to the first aspect, in this possible implementation, the outer peripheral wall of the first insulating shell is further provided with a receiving groove, and the first sealing member is received in the receiving groove.

[0021] In this possible implementation, the receiving groove can position and limit the first seal, which facilitates the assembly of the first seal on the first insulating shell and can also reduce the possibility that the position of the first seal will move due to external impact during the use of the USB connector.

[0022] According to the first aspect, in a possible implementation, the USB connector also includes a third insulating shell, which is sleeved outside the second insulating shell and located outside the shell, and the third insulating shell and the second insulating shell are used to clamp the shell between the third insulating shell and the second insulating shell to fix the second insulating shell to the shell.

[0023] According to the first aspect, in a possible implementation, the second insulating shell includes a base and a flange protruding from the outer peripheral wall of the base; the first insulating shell is passed through the base; the third insulating shell is sleeved on the base, and a clamping groove is formed between the third insulating shell and the flange, and the clamping groove is used to clamp the shell; the electrical connection body is passed through the first insulating shell and the base.

[0024] In this possible implementation, the flanges of the third insulating shell and the second insulating shell cooperate with each other in the axial direction of the USB connector to form a clamping groove to clamp the shell, thereby facilitating assembly and disassembly between the USB connector and the shell.

[0025] According to the first aspect, in a possible implementation manner, an outer wall of the base body is provided with an external thread, an inner peripheral wall of the third insulating shell is provided with an internal thread, and the external thread is threadedly connected with the internal thread.

[0026] In this possible implementation, threaded connection is adopted, which can improve the connection strength between the second insulating shell and the third insulating shell and reduce the possibility of the third insulating shell being separated from the second insulating shell.

[0027] According to the first aspect, in a possible implementation, the USB connector further includes a second seal, which is sleeved on the second insulating shell, and is used to seal the connection between the flange and the shell in the axial direction of the USB connector.

[0028] In this possible implementation, in the axial direction of the USB connector, since the second sealing member is sealed and connected between the flange and the shell, it is beneficial to improve the sealing performance of the USB connector in the axial direction of the USB connector, reduce the possibility of water vapor entering the interior of the USB connector through the gap between the flange and the shell, and improve the reliability of the USB connector.

[0029] According to the first aspect, in a possible implementation manner, a receiving recess is formed on a side of the flange facing the third insulating shell, and the second sealing member is received in the receiving recess.

[0030] In this possible implementation, the receiving recess can position and limit the second seal, making it easier to assemble the second seal on the second insulating shell, and can also reduce the possibility that the position of the second seal will move due to external impact during the use of the USB connector.

[0031] According to the first aspect, in a possible implementation, the USB connector further includes a protective cover component, which is used to be sleeved on the second insulating shell and an end of the electrical connection body away from the circuit board.

[0032] In this possible implementation, the protection cover component is used to protect the electrical connection body.

[0033] According to the first aspect, in a possible implementation, the protective cover component includes a connecting ring, a protective cover and a connecting object, the connecting object is connected between the connecting ring and the protective cover, the connecting ring is sleeved on the second insulating shell and is located outside the shell, in the axial direction of the USB connector, the connecting ring is located between the shell and the third insulating shell, the protective cover is used to be sleeved on the second insulating shell and the end of the electrical connection body away from the circuit board, and the third insulating shell is used to be arranged between the connecting ring and the protective cover.

[0034] In this possible implementation, since the circuit board is disposed between the connecting ring and the flange in the axial direction of the USB connector, the connecting ring and the protective cover are fixedly connected by a connecting object, so that the protective cover component will not be separated from the base, reducing the possibility of the protective cover being lost.

[0035] In a second aspect, an embodiment of the present application further provides a USB connector, comprising a first insulating shell, a second insulating shell, and an electrical connection body. One end of the first insulating shell is slidably connected to the second insulating shell along the axial direction of the USB connector, and the other end of the first insulating shell is connected to the circuit board. The second insulating shell is penetrated in the through hole. The electrical connection body is penetrated in the first insulating shell and the second insulating shell, and one end of the electrical connection body is electrically connected to the circuit board.

[0036] The USB connector provided by the present application has a second insulating shell that is slidably connected to the first insulating shell along the axial direction of the USB connector, and the first insulating shell and the second insulating shell are not locked and fixed to each other. When the USB connector, the shell, and the circuit board are assembled together or used, the second insulating shell can move or float relative to the first insulating shell in the axial direction of the USB connector, so that the USB connector can adapt to different distances between the shell and the circuit board to absorb the assembly tolerance between the USB connector and the shell, and can absorb the stress between the circuit board and the USB connector, which is beneficial to reducing the risk of failure of the electrical connection between the electrical connection body and the circuit board, thereby improving the reliability of the USB connector.

DETAILED DESCRIPTION

[0047] The present application relates to a USB connector, which is suitable for various electronic devices that need to use a USB connector to complete data transmission, specifically, various power equipment, such as photovoltaic inverters, energy storage converters, etc.

[0048] See also Figure 1 , Figure 1 This is a schematic diagram of the architecture of a photovoltaic system 1 applied to a household power station provided in one embodiment of the present application. In this architecture, the power equipment of the present application may be a photovoltaic inverter.

[0049] In one embodiment, the photovoltaic system 1 includes a photovoltaic assembly 20, a photovoltaic optimizer 30, a photovoltaic inverter, an energy storage system 40, an on-grid and off-grid controller 50, and a power sensor 60. This embodiment architecture is applicable to the on-grid and off-grid system architecture of a household power station.

[0050] The photovoltaic optimizer 30 is installed on the photovoltaic module 20, and the photovoltaic module 20 is used to convert light energy into electrical energy. The photovoltaic optimizer 30 is used to improve the power generation efficiency of the photovoltaic module 20. Among them, the photovoltaic optimizer 30 is a component-level power electronic device with DC input and DC output. By connecting it in series with the photovoltaic module 20, the predicted current and voltage technology is adopted to ensure that the module is always in the optimal working state. According to the working principle of the step-down topology, it is used to solve the influence of shadow obstruction, inconsistent orientation or difference in electrical specifications of the module on the power generation of the photovoltaic power station, realize the maximum power output of the module, and improve the power generation of the system.

[0051] The photovoltaic module 20 is electrically connected to the photovoltaic inverter, and the photovoltaic module 20 transmits direct current to the photovoltaic inverter. The photovoltaic inverter is electrically connected to the energy storage system 40 and the on-grid controller 50 respectively.

[0052] In one embodiment, the photovoltaic inverter has a DC conversion functional module, which can be used to convert the DC power generated by the photovoltaic inverter into the voltage required for storing energy in the energy storage system 40, and transmit it to the energy storage system 40 for energy storage.

[0053] In one embodiment, the photovoltaic inverter can convert the direct current provided by the photovoltaic assembly 20 into alternating current, and transmit the alternating current to the on-grid and off-grid controller 50. The on-grid and off-grid controller 50 is electrically connected to the power consumption device 2 on one hand, and can be electrically connected to the power grid 3 on the other hand. In actual application scenarios, the on-grid and off-grid controller 50 can control the photovoltaic system to be in an off-grid state or a grid-connected state.

[0054] When the on-grid controller 50 is in an off-grid state, there is no electrical connection between the on-grid controller 50 and the power grid 3, and the AC power transmitted by the photovoltaic inverter is only provided to the power-consuming device 2. The power-consuming device 2 includes household appliances, for example, including televisions, refrigerators, washing machines, etc.

[0055] When the on-grid and off-grid controller 50 is in the on-grid state, the on-grid and off-grid controller 50 is electrically connected to the power grid 3 through the power sensor 60. When the electric energy generated by the photovoltaic module 20 cannot meet the power demand of the power-consuming device 2, the power grid 3 can provide electric energy to the photovoltaic system 1 through the on-grid and off-grid controller 50. When the power generation of the photovoltaic module 20 exceeds the power used by the power-consuming device 2, the on-grid and off-grid controller 50 can transmit the excess power to the power grid 3. The power sensor 60 is used to measure the power flow between the photovoltaic system 1 and the power grid 3. Exemplarily, the power sensor 60 can be an electric meter.

[0056] In another embodiment of the photovoltaic system architecture of household green electricity, the above-mentioned on-grid and off-grid controller 50 may not be included, that is, the photovoltaic inverter may also be directly connected to the power device 2 and the power grid 3 to directly transmit the AC power to the power device 2. This embodiment architecture is suitable for the grid-connected system architecture of household power stations.

[0057] In some other power stations and industrial and commercial photovoltaic system architectures, the photovoltaic inverter can also be directly connected to the grid 3 to directly transmit AC power to the grid 3.

[0058] It should be noted that Figure 1 The application scenario of the photovoltaic system 1 in a household power station is schematically shown. The photovoltaic system 1 can also be used in an industrial photovoltaic power station. Figure 1 The structure of the photovoltaic system 1 illustrated does not represent the structure, size and position relationship of the internal components of the photovoltaic system 1 , and those skilled in the art may make adjustments according to actual needs.

[0059] The photovoltaic assembly 20 includes at least one photovoltaic panel 21, and the photovoltaic panel 21 is connected to a photovoltaic inverter. In one embodiment, the photovoltaic assembly 20 includes a plurality of photovoltaic panels 21 connected in series, and the direct current of the plurality of photovoltaic panels 21 is collected and connected to the photovoltaic inverter through the series connection.

[0060] Electronic devices are usually connected to external devices via USB (Universal Serial Bus, USB) connectors for data transmission. Generally speaking, USB connectors are connected to circuit boards via cables, i.e., additional internal USB connector interfaces, wiring harnesses, and on-board power connectors of circuit boards are added. This increases the number of components and complicates the structure, and the additional wiring harnesses, on-board power connectors, etc. also increase the risk of reliability. In the present application, one end of the USB connector can be directly extended into the interior of the housing to be electrically connected to the circuit board located inside the housing, and the other end of the USB connector needs to be connected to an external device, so that the USB connector can be connected to the circuit board without cables. However, since the USB connector also needs to be assembled and fixed together with the housing in the electronic device, and there is an assembly tolerance in the spacing between the circuit board and the housing, when the electrical connection conductor of the USB connector is directly assembled on the circuit board, stress will be caused between the USB connector and the circuit board.

[0061] Based on this, see Figure 2 and Figure 3The present application provides an electronic device 10, which includes a housing 101, a circuit board 103 and a USB connector 105. The circuit board 103 is accommodated in the housing 101. The housing 101 is provided with a through hole 1011. The USB connector 105 includes a first insulating shell 11, a second insulating shell 12, and an electrical connection body 13. One end of the first insulating shell 11 is slidably connected to the second insulating shell 12 along the axial direction of the USB connector 105. The second insulating shell 12 is penetrated in the through hole 1011. The electrical connection body 13 is penetrated in the first insulating shell 11 and the second insulating shell 12. One end of the electrical connection body 13 is electrically connected to the circuit board 103.

[0062] The USB connector 105 and the electronic device 10 provided in the present application are axially connected to each other by sliding the second insulating shell 12 and the first insulating shell 11 along the axial direction of the USB connector 105. In this way, the relative positions of the second insulating shell 12 and the first insulating shell 11 in the axial direction can float, so that the USB connector 105 can adapt to different distances between the shell 101 and the circuit board 103 to absorb the assembly tolerance between the USB connector 105 and the shell 101, and can absorb the stress between the circuit board 103 and the USB connector 105, which is beneficial to reduce the risk of failure of the electrical connection between the electrical connection body 13 and the circuit board 103, thereby improving the reliability of the USB connector 105.

[0063] In this embodiment, the USB connector 105 adopts a floating design, and there is no need to set an on-board power connector on the circuit board 103, and there is no need to add an additional internal USB connector interface and wiring harness inside the electronic device 10. In this way, the number of components of the electronic device 10 is reduced, the connection structure between the circuit board 103 and the USB connector 105 is simplified, and the reliability of the electrical connection between the USB connector 105 and the circuit board 103 is reduced.

[0064] In some embodiments of the present application, the USB connector 105 further includes a third insulating shell 14, which is sleeved on the second insulating shell 12 and located outside the housing 101. The third insulating shell 14 is used to cooperate with the second insulating shell 12 to install the USB connector 105 on the housing 101. In some possible implementations, the third insulating shell 14 can be omitted, and the second insulating shell 12 can be directly fixed to the housing 101 by bonding or the like. For example, the second insulating shell 12 is snapped into the through hole 1011.

[0065] See also Figure 3, the second insulating shell 12 also includes a base 122 and a flange 123. The base 122 is sleeved outside the first insulating shell 11 and penetrates the third insulating shell 14, and is used to connect with the third insulating shell 14. The third insulating shell 14 is sleeved outside the base 122, and a clamping groove 126 is formed between the third insulating shell 14 and the flange 123 in the axial direction of the USB connector 105, and the clamping groove 126 is used to clamp the housing 101. When the USB connector 105 and the housing 101 are assembled together, the flange 123 is located in the housing 101, and the flange 123 is located between the third insulating shell 14 and the circuit board 103. The third insulating shell 14 and the flange 123 of the second insulating shell 12 cooperate in the axial direction of the USB to form a clamping groove 126 to clamp the housing 101, so that the housing 101, the second insulating shell 12, and the third insulating shell 14 are assembled together, which facilitates the assembly and disassembly between the USB connector 105 and the housing 101.

[0066] Please refer to Figure 3 , Figure 4 The second insulating shell 12 further includes a plugging protrusion 124, which is protruding from the end surface of the base 122 on the side of the USB connector 105 facing the circuit board 103. In this embodiment, the circuit board 103 is provided with a plugging hole 1031 (such as Figure 3 As shown). The plug-in protrusion 124 is used to be plugged into the plug-in hole 1031 to realize the physical connection between the second insulating shell 12 and the circuit board 103. When the second insulating shell 12 moves relative to the first insulating shell 11, the second insulating shell 12 can move relative to the circuit board 103. The circuit board 103 and the second insulating shell 12 are connected through the plug-in structure. The plug-in hole 1031 and the plug-in protrusion 124 can position the assembly between the circuit board 103 and the second insulating shell 12, which is conducive to improving the assembly accuracy and efficiency between the USB connector 105 and the circuit board 103. It can be understood that the second insulating shell 12 may not be connected to the circuit board 103.

[0067] In this implementation, please refer to Figure 3 One end of the first insulating shell 11 is accommodated in the second insulating shell 12, and the inner wall of the base 122 is provided with a first stop structure 1223, which is used to abut against the first insulating shell 11 in the axial direction of the USB connector 105 to limit the axial relative movement of the second insulating shell 12 and the first insulating shell 11.

[0068] The second insulating shell 12 further includes a slide groove 127 disposed on the inner peripheral wall of the base 122, the first stop structure 1223 is located at the end wall of the slide groove 127 in the axial direction of the USB connector 105, and the outer peripheral wall of the first insulating shell 11 is provided with a protrusion 111, which is received in the slide groove 127, and the protrusion 111 can abut against the first stop structure 1223 in the axial direction of the USB connector 105. Since the first stop structure 1223 is disposed on the end wall of the slide groove 127, that is, the end wall of the reused slide groove 127 is used as a stop structure, the structure of the first insulating shell 11 is simplified. The slide groove 127 can guide the movement of the second insulating shell 12 relative to the first insulating shell 11, thereby improving the smoothness of the movement of the second insulating shell 12 relative to the first insulating shell 11.

[0069] The second insulating shell 12 further includes a second stop structure 1225 disposed on the inner peripheral wall of the base 122, and the second stop structure 1225 is used to abut against the first insulating shell 11 in the axial direction. In the axial direction of the USB connector 105, the distance between the first stop structure 1223 and the circuit board 103 is greater than the distance between the second stop structure 1225 and the circuit board 103. The first stop structure 1223 is used to limit the movement stroke of the second insulating shell 12 away from the circuit board 103, and the second stop structure 1225 is used to limit the movement stroke of the second insulating shell 12 toward the circuit board 103.

[0070] In this implementation, please refer to Figure 3 and Figure 5 The second stop structure 1225 is roughly strip-shaped. One end of the second stop structure 1225 is fixed to the inner peripheral wall of the base 122, and the other end of the second stop structure 1225 is a free end extending toward the circuit board 103. The free end includes a hook protruding toward the inner cavity of the second insulating shell 12, and the hook is used to abut against the end surface of the first insulating shell 11 facing the circuit board 103 in the axial direction of the USB connector. In this way, the deformation ability of the second stop structure 1225 is increased, and the first insulating shell 11 is convenient for passing into the second insulating shell 12.

[0071] In a possible implementation, the axial distance between the circuit board 103 and the housing 101 is D1 (eg Figure 2 and Figure 3 As shown in the figure, when the USB connector 105, the circuit board 103, and the shell 101 are assembled together, the relative positions of the second insulating shell 12 and the first insulating shell 11 along the axial direction of the USB connector 105 are adjusted so that the USB connector 105 is adapted to the axial direction D1 between the circuit board 103 and the shell 101, the USB connector 105 is in the first state, and the first insulating shell 11 is abutted against the first stop structure 1223.

[0072] like Figure 6 and Figure 7As shown, the axial distance between the circuit board 103 and the housing 101 is D2, and D2 is greater than D1. Along the axial direction of the USB connector 105, if the USB connector 105 is initially in the first state, the second insulating shell 12 is moved in a direction away from the circuit board 103 to adjust the distance between the second insulating shell 12 and the circuit board 103, so that the USB connector 105 adapts to the axial distance D2 between the circuit board 103 and the housing 101, thereby adjusting the USB connector 105 from the first state to the second state to effectively absorb the assembly tolerance between the circuit board 103 and the housing 101. When the USB connector 105 is in the second state, there is a gap between the first insulating shell 11 and the first stop structure 1223.

[0073] It is understandable that the USB connector 105 can also switch from the second state to other states. For example, along the axial direction of the USB connector 105 , the second insulating shell 12 can be moved toward the direction where the circuit board 103 is located.

[0074] See also Figure 7 The USB connector 105 further includes a first sealing member 16, which is sleeved outside the first insulating shell 11. In the radial direction of the first insulating shell 11, the first sealing member 16 is sealed and connected between the outer peripheral wall of the first insulating shell 11 and the inner peripheral wall of the second insulating shell 12. In this way, the sealing performance between the first insulating shell 11 and the second insulating shell 12 is improved, and the possibility of water vapor entering the interior of the electronic device 10 from the gap between the outer peripheral wall of the first insulating shell 11 and the inner peripheral wall of the second insulating shell 12 is reduced, thereby improving the reliability of the USB connector 105. The outer peripheral wall of the first insulating shell 11 is also provided with a receiving groove 1113, and the first sealing member 16 is received in the receiving groove 1113. The receiving groove 1113 can position and limit the first sealing member 16, which is convenient for the first sealing member 16 to be assembled on the first insulating shell 11, and can also reduce the possibility that the position of the first sealing member 16 will move due to external impact during the use of the USB connector 105.

[0075] The USB connector 105 further includes a second sealing member 17, which is sleeved on the second insulating shell 12, and is used to be sealed and connected between the flange 123 and the housing 101 in the axial direction of the USB connector 105. In the axial direction of the USB connector 105, since the second sealing member 17 is sealed and connected between the flange 123 and the housing 101, it is beneficial to improve the sealing performance of the USB connector 105 in the axial direction of the USB connector 105, reduce the possibility of water vapor entering the interior of the USB connector 105 from the gap between the flange 123 and the housing 101, and improve the reliability of the USB connector 105.

[0076] The flange 123 forms a receiving recess 1231 on one side facing the fixing sleeve, and the second sealing member 17 is received in the receiving recess 1231. The receiving recess 1231 can position and limit the second sealing member 17, making it convenient for the second sealing member 17 to be assembled on the second insulating shell 12, and can also reduce the possibility that the position of the second sealing member 17 will move due to external impact during the use of the USB connector 105.

[0077] In this embodiment, the outer peripheral wall of the base 122 is provided with an external thread, the third insulating shell 14 is a nut, and the inner peripheral wall of the third insulating shell 14 is provided with an internal thread. The threaded connection is adopted to improve the connection strength between the second insulating shell 12 and the third insulating shell 14. The present application does not limit the structure of the third insulating shell 14, and the connection method between the second insulating shell 12 and the third insulating shell 14 is not limited to the threaded connection. For example, the second insulating shell 12 and the third insulating shell 14 can be connected by interference locking, clamping, screw fastening, etc.

[0078] In this implementation, please refer to Figure 8 The USB connector 105 further includes a protective cover component 19, which is used to be sleeved on the base 122 and the second end of the electrical connection body 13 to protect and seal the interface of the electrical connection body 13 and reduce the possibility of water vapor entering the interface.

[0079] At least part of the protective cover component 19 is located on the side of the third insulating shell 14 away from the flange 123 in the axial direction of the USB connector 105. The protective cover component 19 includes a connecting ring 194, a protective cover 195, and a connecting object 196. The connecting object 196 is connected between the connecting ring 194 and the protective cover 195. The connecting ring 194, the protective cover 195, and the connecting object 196 can be formed in one piece or in separate pieces. The connecting ring 194 and the protective cover 195 are both sleeved on the base 122. In the axial direction of the USB connector 105, the connecting ring 194 is accommodated in the clamping groove 126, the connecting ring 194 is located between the third insulating shell 14 and the flange 123, and the third insulating shell 14 is located between the connecting ring 194 and the protective cover 195.

[0080] The protective cover 195 is used to be sleeved on the base 122 and cover the base 122 and the second end of the electrical connection body 13. When the USB connector 105, the housing 101, and the circuit board 103 are assembled together, the housing 101 is located between the connecting ring 194 and the second sealing member 17, and the housing 101 fits the connecting ring 194. Since the circuit board 103 is arranged between the connecting ring 194 and the flange 123 in the axial direction of the USB connector 105. The connecting ring 194 and the protective cover 195 are fixedly connected by the connecting object 196, so that the protective cover component 19 will not be separated from the base 122, reducing the possibility of losing the protective cover 195. It can be understood that the protective cover component 19 can omit the connecting ring 194 and the connecting object 196.

[0081] In this embodiment, the inner wall of the protective cover 195 is provided with an internal thread, and the internal thread of the protective cover 195 is screwed with the external thread of the base 122 to achieve a fixed connection between the second insulating shell 12 and the protective cover 195 .
