Description

USB interface connectors and electronic devices

[0001] This application claims priority to Chinese patent application filed on January 15, 2025, with application number 202510068554.3 and entitled "USB Interface Connector and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic product technology, and in particular to a USB interface connector and electronic device. Background Technology

[0003] Electronic devices such as mobile phones, tablets, laptops, and power adapters typically have USB interfaces (e.g., Type-C interfaces) to enable functions such as data transfer, charging, and connection to external devices.

[0004] However, as the size of USB connectors shrinks, the installation space available for them also decreases. Existing USB connectors pose a risk of interference or scratching between the connector and the housing when assembled into electronic devices, potentially leading to improper connector assembly and hindering mass production. Summary of the Invention

[0005] This application provides a USB interface connector and an electronic device, which can solve the problem of interference and scratches between the USB interface connector and the housing of the electronic device, improve the positioning reliability of the USB interface connector, and facilitate the mass production of the electronic device.

[0006] One aspect of this application provides a USB interface connector for encapsulation onto a circuit board and installation in the housing of an electronic device. The USB interface connector includes: a conductive core; an outer frame sleeved on the outer periphery of the conductive core, with a stop portion provided at one end of the outer frame facing into the housing; wherein the stop portion includes a stop wall extending along the height direction of the outer frame and abutting against a first limiting wall of the housing.

[0007] The USB interface connector provided in this application includes a conductive core and an outer frame, with the outer frame fitted around the outer periphery of the conductive core. A stop portion is provided at one end of the outer frame facing into the housing of the electronic device, and a stop wall is designed on the stop portion, extending along the height direction of the outer frame. Thus, when the USB interface connector is installed in the housing of the electronic device, it is positioned at the first limiting wall by the abutment between the stop wall of the outer frame and the first limiting wall of the housing. This design prevents interference and abrasion between the USB interface connector and the housing, improving the assemblability of the USB interface connector. Furthermore, the larger contact area between the stop wall and the first limiting wall enhances the positioning reliability of the USB interface connector. Therefore, it is more conducive to the mass production and assembly of the entire electronic device.

[0008] In one possible implementation, the first end of the stop wall is connected to the outer frame, and the second end of the stop wall extends away from the circuit board.

[0009] In this way, the stop wall extends in the opposite direction to the circuit board, ensuring that it does not interfere with the connection between the circuit board and the USB interface connector. Furthermore, the stop wall extends towards the middle plate, making it easier for it to abut against the first limiting wall of the middle plate, resulting in a more secure positioning of the USB interface connector.

[0010] In one possible implementation, the stop portion further includes a guide wall connected to the second end of the stop wall, and the guide wall extends obliquely away from the first limiting wall.

[0011] In this way, guided by the guide wall, the stop wall can smoothly abut against the first limiting wall. This prevents the stop part of the outer shell from scraping against the first limiting wall of the middle plate, allowing the USB interface connector to be smoothly installed on the middle frame, thus ensuring the installation reliability of the USB interface connector.

[0012] In one possible implementation, the stop portion further includes a reinforcing wall connected to at least one of the left and right sides of the stop wall, the reinforcing wall extending from the stop wall to the other end of the outer frame.

[0013] In this way, the reinforcing wall increases the total surface area of ​​the stop, enhancing its structural strength. The included angle between the reinforcing wall and the stop wall allows the reinforcing wall to better distribute and counteract the forces acting on the stop wall, helping it resist deformation and improving its reliability.

[0014] In one possible implementation, the reinforcing wall is perpendicular to the stop wall.

[0015] In this way, the force transmission direction between the stop wall and the first limiting wall is mainly concentrated in the plane direction of the reinforcing wall. The force on the stop wall can be more fully transmitted to the reinforcing wall, resulting in better impact resistance, higher stability, and greater reliability of the stop wall.

[0016] In one possible implementation, the stops are located at both ends of the outer frame in the width direction.

[0017] In this way, the stop portion can avoid the contact end of the conductive core, and the contact end of the conductive core can be located between the stop portions at both ends of the outer shell, ensuring that the circuit board can connect to the contact end of the conductive core. Moreover, the force generated between the stop portions at both ends of the outer shell and the first limiting wall can balance the force on the entire USB interface connector, improving the reliability and service life of the USB interface connector.

[0018] In one possible implementation, the stop is integrally formed into the outer frame.

[0019] This makes the manufacturing process of the outer frame simpler, more efficient, and results in better overall integrity, consistency, and structural strength.

[0020] In one possible implementation, the outer frame is further provided with a claw portion that extends toward the circuit board and is configured to be inserted into a mounting hole on the circuit board.

[0021] In this way, by inserting the claws into the assembly hole, the USB interface connector can be positioned on the circuit board, improving the assembly accuracy between the USB interface connector and the circuit board and ensuring that the power connector's contact end is aligned with the power pads on the circuit board. Furthermore, by fixing the claws in place within the assembly hole, the USB interface connector connection is ensured to be stable, preventing the USB interface connector from tilting at the power contact end of the conductive core due to gravity, thus improving the reliability of the connection between the power contact end of the conductive core and the circuit board.

[0022] In one possible implementation, the claw portions are located at both ends of the outer frame in the width direction.

[0023] In this way, the claw portion does not occupy the area directly in front of the first end of the housing, avoiding the power connection terminal of the conductive core and not affecting the connection between the circuit board and the power connection terminal of the conductive core. Furthermore, the claw portion is not located on the top surface of the housing, avoiding areas not covered by the circuit board, facilitating the mating of the claw portion and the circuit board. In addition, both ends of the housing are connected to the circuit board via the claw portion, ensuring a balanced connection between the USB interface connector and the circuit board, resulting in high connection reliability.

[0024] In one possible implementation, the outer frame includes a first frame and a second frame that are joined together along the height direction, a stop portion is disposed on the first frame, and a claw portion is disposed on the second frame.

[0025] In this way, the first frame is located on the side of the outer casing near the middle plate. By setting the stop part on the first frame, it is easy to extend the stop part toward the middle plate without interfering with the second frame. The second frame is located on the side of the outer casing near the circuit board. By setting the claw part on the second frame, it is easy to extend the claw part toward the circuit board without interfering with the first frame.

[0026] In one possible implementation, both the first frame and the second frame include a main body and a docking part, with the docking part located at both ends of the main body; the main body of the first frame and the main body of the second frame together enclose a space for accommodating the conductive core, and the docking parts of the first frame and the second frame are relatively fitted together; wherein, a stop part is provided at the docking part of the first frame, and a claw part is provided at the docking part of the second frame.

[0027] In this way, both the main body of the first frame and the main body of the second frame can be semi-annular structures, and the main bodies of the first frame and the second frame together enclose an accommodating space, within which the conductive core and the inner frame are inserted. The mating parts of the first frame and the second frame are fitted together to achieve the connection between the first frame and the second frame. By placing the stop part on the mating part of the first frame and the claw part on the mating part of the second frame, it is convenient for the stop part to abut against the first limiting wall, and also convenient for the claw part to be inserted into the circuit board, without affecting the fit and connection between the mating parts of the first frame and the second frame.

[0028] In one possible implementation, the USB interface connector further includes: an inner frame disposed within an outer frame, with a conductive core inserted into the inner frame; wherein, one end of the inner frame facing outwards abuts against a second limiting wall of the housing, the second limiting wall being disposed opposite to the first limiting wall.

[0029] This allows the inner frame to be designed as a one-piece ring frame, through which the USB interface connector can abut against the second limiting wall of the housing. The seamless one-piece inner frame enables a better sealing connection between the outer shell and the middle frame, improving the sealing performance of the electronic device.

[0030] In one possible implementation, the inner frame includes an integrally formed main frame and a flanged portion, the flanged portion being folded outward at the end of the main frame facing outward from the housing, and the flanged portion abutting against the second limiting wall.

[0031] In this way, the inner frame abuts against the second limiting wall of the middle frame (e.g., the inner side wall of the frame portion) via the flanged portion, and the seal is disposed between the flanged portion and the second limiting wall. Furthermore, by integrally molding the flanged portion at the second end of the main frame, the assembly steps for the USB interface connector can be reduced, improving the assembly efficiency of the USB interface connector. Moreover, since there are no assembly tolerance issues, the flanged portion has high positional accuracy, which can precisely provide the mounting position for the seal, ensuring that the seal tightly seals the gap between the inner frame and the electronic device's housing, thus improving the overall sealing performance of the electronic device.

[0032] In one possible implementation, the flanged portion includes a first segment and a second segment extending sequentially from the main frame, the first segment extending toward the interior of the housing and the second segment extending away from the main frame.

[0033] In this way, the second section can form a mounting surface facing the second limiting wall of the housing. This mounting surface can be used to receive the seal, so that the seal can be squeezed by the second section of the flange. The first section, located between the main frame and the second section, can support the second section. The force on the second section can be transmitted to the main frame through the first section, thereby enhancing the structural strength and reliability of the flange.

[0034] In one possible implementation, the first segment is attached to the outer wall of the main frame, and the second segment is perpendicular to the first segment.

[0035] In this way, the first section is supported by the outer wall of the main frame, allowing for more efficient force transfer between the first section and the main frame. The second section can remain parallel to the second limiting wall, ensuring a tight seal between the second section and the second limiting wall, and resulting in a more balanced force distribution on the second section. Consequently, the overall support of the flange is better, and the flange's resistance to deformation is stronger.

[0036] In one possible implementation, the inner frame and the second limiting wall are in sealed contact by a seal.

[0037] In this way, the gap between the inner frame and the middle frame is sealed by the sealing element, thus achieving a sealed connection between the USB interface connector and the middle frame.

[0038] In one possible implementation, the conductive core includes: a main core; and a protective frame fitted around the outer periphery of the main core.

[0039] In this way, the main core is used to transmit signals, realizing the function of the USB interface connector. The protective frame is fitted around the outer periphery of the main core to protect it and enhance the integrity and reliability of the conductive core.

[0040] In one possible implementation, the protective frame includes a base and an extension, the extension being connected to the side of the base facing outwards from the housing, and the extension being located in the central region of the base in the height direction.

[0041] In this way, the height of the base of the protective frame matches the inner height of the outer shell (the distance between the two inner walls of opposite sides in the height direction of the outer shell), and the base fits against the inner wall of the inner frame to position the conductive core inside the outer shell. The height of the extension of the protective frame can be less than the inner height of the outer shell, and there can be gaps between the two side surfaces of the extension and the two side inner surfaces of the outer shell.

[0042] Furthermore, by positioning the extension in the center of the base, the main core can be positioned, ensuring the centering of the main core's insertion end in the height direction of the USB connector. This improves the positional accuracy of the main core, ensuring reliable insertion between the USB connector and the USB interface connector, and achieving stable and continuous signal transmission.

[0043] In one possible implementation, a notch is provided at one end of the protective frame facing outward from the housing. The notch is located on opposite sidewalls in the height direction of the protective frame, and the voltage terminals of the main core are located within the coverage area of ​​the notch.

[0044] In this way, within the coverage area of ​​the notch, the portion of the conductive terminal exposed on the surface of the main core is further away from the end of the protective frame facing the main core. This increased spacing between the conductive terminal and the end face of the protective frame reduces the risk of short circuits in the conductive core and enhances the reliability of signal transmission. Furthermore, by placing the voltage terminals within the coverage area of ​​the notch, the risk of short circuits in the voltage terminals is reduced, ensuring the operational reliability of the USB interface connector.

[0045] Another aspect of this application provides an electronic device including a housing and a USB interface connector as described above, the USB interface connector being mounted on the housing.

[0046] The electronic device provided in this application, since it includes the aforementioned USB interface connector, possesses all the technical effects of a USB interface connector, which will not be elaborated here. Attached Figure Description

Detailed Implementation

[0066] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0067] This application provides an electronic device, which can be a consumer electronics product. Exemplary examples include, but are not limited to, mobile phones, portable Android devices (PADs), laptops, laptop computers, netbooks, ultra-mobile personal computers (UMPCs), walkie-talkies, point-of-sale (POS) machines, personal digital assistants (PDAs), multimedia players, e-book readers, in-vehicle devices, wearable devices, virtual reality (VR) devices, and augmented reality (AR) devices. Wearable devices include, but are not limited to, smart bracelets, smartwatches, smart head-mounted displays, and smart glasses.

[0068] Figure 1 is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Referring to Figure 1, the electronic device 10 is taken as a candybar electronic device (e.g., a candybar mobile phone). The electronic device 10 includes a display screen 100 and a housing 200. One side surface of the display screen 100 is used to display image information, and this side surface of the display screen 100 is generally defined as its front side, and the other side surface opposite to its front side is its back side. The housing 200 surrounds the periphery and back side of the display screen 100, and is used to support and fix the display screen 100 and provide protection. The front side of the display screen 100 is exposed outside the housing 200 so that the user can view the content displayed on the display screen 100 or perform input operations on the electronic device 10.

[0069] The display screen of the candybar electronic device can be a rigid screen. For example, the display screen 100 can be an LCD (Liquid Crystal Display) display screen or an OLED (Organic Light-Emitting Diode) display screen.

[0070] Figure 2 is an exploded structural diagram of the electronic device shown in Figure 1. Referring to Figure 2, the housing 200 of the electronic device 10 may include a middle frame 210 and a back cover 220. The middle frame 210 is connected between the display screen 100 and the back cover 220. The display screen 100 is supported on one side surface of the middle frame 210, and the back cover 220 is connected to the other side surface of the middle frame 210. The middle frame 210 and the back cover 220 together form a receiving cavity, in which functional devices such as a circuit board 300, a battery 400, a camera 500, and a microphone (not shown in the figure) are installed.

[0071] The mid-frame 210 may include a mid-plate portion 211 and a frame portion 212. The mid-plate portion 211 is located between the display screen 20 and the back cover 220, and is generally arranged parallel to the display screen 20 and the back cover 220. The frame portion 212 surrounds the periphery of the mid-plate portion 211, and the frame portion 212 may extend perpendicularly to both sides of the mid-plate portion 211. For example, the frame portion 212 and the mid-plate portion 211 may be an integrally formed structure.

[0072] The display screen 20 is typically mounted on the middle plate 211 of the middle frame 210. The middle plate 211 supports the display screen 20, ensuring it is stable and secure. This provides the display screen 20 with sufficient strength to withstand frequent pressure. The frame 212 surrounds the display screen 20, protecting its edges and helping it withstand impacts, drops, and other risks, preventing damage.

[0073] The edge of the back cover 220 is connected to the side frame portion 212 of the middle frame 210, for example, the edge of the back cover 220 is bonded to the side frame portion 212. A gap exists between the middle plate portion 211 of the middle frame 210 and the back cover 220, forming a receiving cavity as described above, for mounting a device within the receiving cavity between the middle plate portion 211 of the middle frame 210 and the back cover 220. Exemplarily, the back cover 220 may be generally flat, with its edge overlapping the side frame portion 212 of the middle frame 210, the entire back cover 220 situated within the area enclosed by the side frame portion 212. Alternatively, the back cover 220 may have a flange that bends towards the middle frame 210, surrounding the outside of the side frame portion 212 of the middle frame 210 and enclosing the middle frame 210 within it.

[0074] Of course, electronic device 10 can also be a foldable electronic device (e.g., a foldable phone). A foldable electronic device may include at least two parts that can rotate relative to each other, and the foldable electronic device may have different usage states in different usage scenarios.

[0075] The housing 200 assembly of the foldable electronic device may include at least two housings 200 and a pivot, with adjacent housings 200 rotatably connected by the pivot. The pivot can enable the relative folding and unfolding of two adjacent housings 200, thereby switching the housing 200 assembly between a folded state and an unfolded state.

[0076] The display screen 100 of the foldable electronic device may include a foldable screen. The housing 200 assembly switches between a folded state and an unfolded state, causing the foldable screen to fold or unfold accordingly. If the foldable electronic device has an inward-folding architecture, when the electronic device 10 is in the folded state, the foldable screen is enclosed within the housing 200 and is not visible to the outside. In this case, the electronic device 10 may also be equipped with a flat screen, which is disposed on the surface of the housing 200 opposite to the foldable screen. In the folded state, the inward-folding foldable electronic device relies on the flat screen for display.

[0077] In the housing 200 assembly of the foldable electronic device, the housing 200 may also include a mid-frame 210 and a back cover 220. The mid-frame 210 and the back cover 220 (or a flat screen) together form a receiving cavity, in which functional devices such as a circuit board 300, a battery 400, a camera 500, and a microphone are installed. The mid-frame 210 may include a middle plate portion 211 and a side frame portion 212 surrounding the middle plate portion 211, which will not be described in detail here.

[0078] As electronic devices 10 continue to evolve towards thinner and lighter designs, new challenges are constantly being presented to the thinner and lighter design of the hardware configured within them. For example, the USB interface connector 600, which is located in the electronic device 10, is also being designed to reduce its length. Due to the reduced length of the USB interface connector 600, the installation space available for it is also less. Conventional device positioning methods can no longer meet the high-precision positioning requirements of the device.

[0079] Figure 3 is a structural schematic diagram of a USB interface connector in related technologies. Figure 4 is a cross-sectional structural diagram of the USB interface connector in Figure 3 in an electronic device.

[0080] Referring to Figure 3, taking the USB interface connector 600 (connector female) as an example of a Type-C interface connector, the USB interface connector 700 may include a conductive core 710 and a housing 720, with the housing 720 sleeved around the outer periphery of the conductive core 710. In related technologies, the USB interface connector 700 is typically positioned within the housing 200 of the electronic device 10 by the end face of its housing 720 (shown by the dashed box in Figure 3).

[0081] Referring to Figure 4, the USB interface connector 700 is mounted on the middle frame 210 of the housing 200. A through-hole 2121 is provided on the edge portion 212 of the middle frame 210. A positioning groove 2111 may also be formed on the middle plate portion 211 of the middle frame 210, located at the edge region of the middle plate portion 211 and extending to communicate with the 2121. The housing 720 of the USB interface connector 700 is disposed within the positioning groove 2111 and abuts against the edge portion 212, and the conductive core 710 of the USB interface connector 700 extends into the 2121 of the edge portion 212. The USB interface connector head (connector male socket) is inserted into the 2121 of the edge portion 212 to achieve electrical connection with the USB interface connector 700.

[0082] In this design, one end face of the outer shell 720 of the USB interface connector 700 facing inwards from the housing 200 (shown by the dashed box in Figure 3) abuts against the groove wall of the positioning groove 2111 on the middle plate portion 211 of the middle frame 210 (shown by the dashed box in Figure 4). This provides compressive force to the sealing ring 800 provided on the other end face of the outer shell 720 of the USB interface connector 700, ensuring tight contact between the sealing ring 800 and the frame portion 212. This achieves positioning and waterproof sealing of the USB interface connector 700.

[0083] However, with the extreme reduction in size of the USB interface connector 700, there is a risk of interference or scratching between the USB interface connector 700 and the middle frame 210 during installation (as shown in the dotted box in Figure 4), which may easily lead to improper assembly of the device and is not conducive to the mass production of the entire electronic device 10.

[0084] Furthermore, since the tail end of the conductive core 710 of the USB interface connector 700 (the end extending towards the middle plate 211) needs to be encapsulated in the circuit board 300, the tail end of the conductive core 710 usually protrudes beyond the housing 720. When the end face of the housing 720 abuts against the groove wall of the positioning groove 2111, the tail end of the conductive core 710 needs to be accommodated so that it can be suspended above the middle plate 211. Therefore, the groove depth of the positioning groove 2111 on the middle plate 211 needs to be designed, and the groove depth cannot exceed the distance between the bottom surface of the housing 720 and the tail end of the conductive core 710. Consequently, the portion of the USB interface connector 700 embedded within the middle plate 211 is small, while the portion of the USB interface connector 700 above the middle plate 211 is larger. Corresponding to the position of the USB interface connector 700, the frame portion 212 also needs to reserve enough space to open the insertion hole 2121. This makes the frame portion 212 thicker, which is not conducive to reducing the thickness of the middle frame 210, and thus affects the overall thinness of the electronic device 10.

[0085] In view of this, this application provides a USB interface connector 600, which includes a conductive core 610 and an outer frame 621, with the outer frame 621 sleeved around the outer periphery of the conductive core 610. A stop portion 6211 is provided at one end of the outer frame 621 facing into the housing 200 of the electronic device 10, and a stop wall 62111 is designed on the stop portion 6211, extending along the height direction of the outer frame 621. Thus, when the USB interface connector 600 is installed in the housing 200 of the electronic device 10, the stop wall 62111 of the outer frame 621 abuts against the first limiting wall 201 of the housing 200, positioning the USB interface connector 600 at the first limiting wall 201. This arrangement prevents interference and abrasion between the USB interface connector 600 and the housing 200, improving the assemblability of the USB interface connector 600. Furthermore, the larger contact area between the stop wall 62111 and the first limiting wall 201 improves the positioning reliability of the USB interface connector 600. This, in turn, facilitates the mass production and assembly of the entire electronic device 10.

[0086] Figure 5 is a partial structural diagram of the electronic device provided in an embodiment of this application from one perspective. Figure 6 is a partial structural diagram of the electronic device provided in an embodiment of this application from another perspective.

[0087] Referring to Figure 5, a partial structure of the electronic device 10 at the location of the USB interface connector 600 is shown. Specifically, the USB interface connector 600 is encapsulated on a circuit board 300 disposed within the housing 200 of the electronic device 10. The circuit board 300 can be mounted on the mid-frame 210 of the housing 200 to fix the circuit board 300 within the housing 200. Typically, the electronic device 10 contains two or more circuit boards 300, which may include a main board and a sub-board. The main board integrates the core components of the electronic device 10. Components that cannot be integrated onto the main board due to limitations in component placement or main board layout area can be disposed on the sub-board. The circuit board 300 used to encapsulate the USB interface connector 600 can be a sub-board, which is electrically connected to the main board (e.g., via a flexible circuit board) to control the USB interface connector 600 through the main board.

[0088] Referring to FIG6, the housing 200 of the electronic device 10 has a plug hole 2121, which can be located on the side frame 212 of the middle frame 210. The USB interface connector 600 extends into the plug hole 2121 of the housing 200, so that part of the USB interface connector 600 is exposed in the plug hole 2121. The USB interface connector head is inserted into the plug hole 2121 and mates with the USB interface connector 600.

[0089] Figure 7 is a partially exploded structural view of the electronic device provided in an embodiment of this application. Referring to Figure 7, a positioning groove 2111 is provided on the middle plate portion 211 of the middle frame 210. The positioning groove 2111 is located in the edge region of the middle plate portion 211, and the positioning groove 2111 corresponds to the insertion hole 2121 on the side frame portion 212 of the middle frame 210. The positioning groove 2111 is connected to the insertion hole 2121. Taking the insertion groove being located in the middle region of one side (e.g., the wide side) of the side frame portion 212 as an example, the positioning groove 2111 can be located in the middle region of that side edge of the middle plate portion 211.

[0090] The USB interface connector 600 is at least partially embedded in the positioning groove 2111 to position the USB interface connector 600 within the middle frame 210. A circuit board 300 for encapsulating the USB interface connector 600 can be mounted on the surface of the middle frame 211. The circuit board 300 and the middle frame 211 have a large contact area, ensuring the stability and reliability of the circuit board 300. The depth of the positioning groove 2111 can be less than the total thickness of the USB interface connector 600, and a portion of the USB interface connector 600 protrudes above the surface of the middle frame 211.

[0091] In other embodiments, the thickness of the middle plate portion 211 of the middle frame 210 can be relatively large, and the depth of the positioning groove 2111 formed on the middle plate portion 211 can be relatively large, so that the USB interface connector 600 can be completely accommodated within the positioning groove 2111 without protruding above the surface of the middle plate portion 211. Alternatively, when the thickness of the middle plate portion 211 of the middle frame 210 is too small to be suitable for forming the positioning groove 2111, the USB interface connector 600 can also be completely supported on the surface of the middle plate portion 211. In this case, there may be a certain gap between the circuit board 300 and the surface of the middle plate portion 211. A support structure can be provided on the surface of the middle plate portion 211 to support and fix the circuit board 300 to the middle plate portion 211.

[0092] Figure 8 is a structural schematic diagram of the USB interface connector provided in an embodiment of this application from one perspective. Figure 9 is an exploded structural diagram of the USB interface connector in Figure 8.

[0093] As shown in Figures 8 and 9, the USB interface connector 600 includes a conductive core 610 and a housing 620, with the housing 620 fitted around the outer periphery of the conductive core 610. As the core functional part of the USB interface connector 600, it is used to realize the signal transmission function of the USB interface connector 600. The housing 620 protects the conductive core 610, providing high structural strength for the overall USB interface connector 600 and improving its reliability. The USB interface connector 600 can be installed in the electronic device 10 using its housing 620, ensuring a secure installation and preventing damage to the conductive core 610.

[0094] The USB interface connector 600 has an open-end structure for its housing 620. The conductive core 610 passes through the housing 620, with both ends of the conductive core 610 extending beyond the housing 620 (see Figure 8). This allows for electrical contact between the conductive core 610 and the USB interface connector, as well as electrical connection between the conductive core 610 and the circuit board 300. Therefore, signals can be transmitted between the USB interface connector 600 and the circuit board 300.

[0095] For ease of explanation, in this embodiment, the two ends of the extension direction of the outer shell 620 (the X direction shown in FIG. 5) are defined as the first end and the second end, respectively. The first end of the outer shell 620 faces inward toward the inner side of the housing 200 and away from the side frame 212 of the middle frame 210, while the second end of the outer shell 620 faces outward toward the outer side of the housing 200 and toward the side frame 212 of the middle frame 210. The portion of the conductive core 610 extending beyond the first end of the outer shell 620 can be considered as the power receiving end 601 of the conductive core 610, which can be encapsulated on the circuit board 300. The portion of the conductive core 610 extending beyond the second end of the outer shell 620 can be considered as the insertion end 602 of the conductive core 610. The insertion end 602 of the conductive core 610 extends into the insertion hole 2121 on the side frame 212, and the USB interface connector can be inserted into the insertion end 602 of the conductive core 610 for communication.

[0096] When the USB interface connector 600 is installed on the middle frame 210, it can be positioned on the middle frame 210 by the outer shell 620. The first end of the outer shell 620 can abut against the first limiting wall 201 of the housing 200, and the second end of the outer shell 620 can abut against the second limiting wall 202 of the housing 200. The first limiting wall 201 and the second limiting wall 202 are arranged opposite to each other to confine the USB interface connector 600 between the first limiting wall 201 and the second limiting wall 202. For example, the first limiting wall 201 is one side wall of the positioning groove 2111 opened on the middle plate portion 211 of the middle frame 210. Specifically, the first limiting wall 201 can be one side wall of the positioning groove 2111 opposite to the side frame portion 212. The second limiting wall 202 can be the inner side wall of the side frame portion 212 (the side wall of the side frame portion 212 facing the middle plate portion 211). When the USB interface connector 600 is fully supported on the surface of the middle plate 211, the first limiting wall 201 can also be a protruding support structure on the middle plate 211.

[0097] Figure 10 is a structural schematic diagram of the USB interface connector in Figure 8 from another perspective. Figure 11 is a partial cross-sectional view of the electronic device along line AA in Figure 5. Figure 12 is a partial cross-sectional view of the electronic device along line BB in Figure 5. Figure 13 is an assembly structure diagram of the USB interface connector and circuit board in Figure 8.

[0098] It should be noted that Figure 8 mainly shows the view of the USB interface connector 600 from the side facing away from the middle plate portion 211 of the middle frame 210, while Figure 10 mainly shows the view of the USB interface connector 600 from the side facing the middle plate portion 211 of the middle frame 210. Referring to Figure 10, in this embodiment, a stop portion 6211 is provided at the first end of the housing 620 of the USB interface connector 600. The stop portion 6211 extends out of the first end of the housing 620, and the USB interface connector 600 can abut against the first limiting wall 201 on the middle plate portion 211 by relying on the stop wall 62111.

[0099] In this embodiment, the stop portions 6211 can be disposed at both ends of the width direction (Y direction shown in FIG. 5) of the housing 620. In this way, the stop portions 6211 can avoid the contact end 601 of the conductive core 610, and the contact end 601 of the conductive core 610 can be located between the stop portions 6211 at both ends of the housing 620, ensuring that the circuit board 300 can connect to the contact end 601 of the conductive core 610. Furthermore, the presence of stop portions 6211 at both ends of the housing 620, and the force generated between the stop portions 6211 at both ends and the first limiting wall 201, can balance the overall force on the USB interface connector 600, improving the reliability of the USB interface connector 600 and extending its service life.

[0100] Furthermore, when the contact end 601 of the conductive core 610 extends beyond the stop wall 62111 provided at the first end of the outer casing 620, the positioning groove 2111 opened on the middle plate portion 211 can be designed as a stepped groove (see Figure 7). The positioning groove 2111 may include a main groove portion 21111 and an expanded groove portion 21112 that are connected to each other. The expanded groove portion 21112 is located on the side of the main groove portion 21111 away from the frame portion 212, and the groove width of the expanded groove portion 21112 is smaller than the groove width of the main groove portion 21111. The first limiting wall 201 is a stepped groove wall formed between the expanded groove portion 21112 and the main groove portion 21111. The stop wall 62111 abuts against this stepped groove wall, and the contact end 601 of the conductive core 610 can be located inside the expanded groove portion 21112.

[0101] Of course, without interfering with the electrical connection terminal 601 of the conductive core 610, the stop portion 6211 can extend from one end to the other in the width direction of the outer shell 620, or multiple stop portions 6211 can be provided at intervals along the width direction of the outer shell 620. This embodiment does not impose specific limitations on this. The following description will take the example of the stop portions 6211 being provided at both ends in the width direction of the outer shell 620.

[0102] Specifically, the stop portion 6211 provided on the housing 620 of the USB interface connector 600 may include a stop wall 62111. The stop wall 62111 extends along the height direction of the housing 620 (the Z direction shown in FIG. 5) and may be parallel to the end face of the first end of the housing 620. Referring to FIG. 11 or FIG. 12, the USB interface connector 600 can be positioned by relying on the stop wall 62111. The stop wall 62111 provided at the first end of the housing 620 abuts against the first limiting wall 201 of the middle frame 210, and the second end of the housing 620 abuts against the second limiting wall 202 of the middle frame 210, thus restricting the housing 620 between the first limiting wall 201 and the second limiting wall 202. Since the stop wall 62111 extends along the height direction of the outer shell 620, the stop wall 62111 and the first limiting wall 201 are parallel to each other, and the stop wall 62111 and the first limiting wall 201 are in a face-to-face contact contact manner.

[0103] With this configuration, when the USB interface connector 600 is installed on the middle frame 210, an external force is applied to the first end of the housing 620 of the USB interface connector 600 toward the frame portion 212. As long as the stop wall 62111 on the housing 620 can contact the first limiting wall 201, the first limiting wall 201 can press against the stop wall 62111 and guide the installation, causing the stop wall 62111 to slide along the first limiting wall 201 toward the middle plate portion 211 until the USB interface connector 600 abuts against the surface of the middle plate portion 211 (e.g., the bottom of the positioning groove 2111). This prevents the housing 620 of the USB interface connector 600 from interfering with or rubbing against the middle frame 210, and prevents the housing 620 from failing to cross the first limiting wall 201 and abutting against it. Therefore, the USB interface connector 600 is easier to install and has higher installation reliability.

[0104] Furthermore, because the stop wall 62111 on the outer shell 620 of the USB interface connector 600 is in surface-to-surface contact with the first limiting wall 201 on the middle frame 210, the contact area between the stop wall 62111 and the first limiting wall 201 is large, resulting in a stronger mutual pushing force between them. This makes the overall force distribution on the USB interface connector 600 more balanced, improving its stability on the middle frame 210 and enhancing its positioning reliability. Consequently, the USB interface connector 600 has better installability, which is more conducive to the mass production and assembly of the electronic device 10.

[0105] The first end of the stop wall 62111 is connected to the housing 620 of the USB interface connector 600, and the second end of the stop wall 62111 extends away from the circuit board 300 (see Figure 11 or Figure 13). That is, the stop wall 62111 can extend towards the middle plate portion 211, for example, towards the bottom of the positioning groove 2111 of the middle plate portion 211. In this way, the extension direction of the stop wall 62111 is opposite to that of the circuit board 300, and the stop wall 62111 will not interfere with the connection between the circuit board 300 and the USB interface connector 600. Furthermore, the stop wall 62111 extending towards the middle plate portion 211 makes it easier for the stop wall 62111 to abut against the first limiting wall 201 of the middle plate portion 211, resulting in a larger contact area between the stop wall 62111 and the first limiting wall 201, and a more secure positioning of the USB interface connector 600.

[0106] It is understood that the stop wall 62111, connected to the first end of the housing 620, should have sufficient clearance from the bottom surface of the housing 620 (the surface of the housing 620 that is attached to the middle plate portion 211 (e.g., the bottom of the positioning groove 2111)). This clearance should be greater than or equal to the extension height of the stop wall 62111 to prevent the stop wall 62111 from interfering with the contact surface of the bottom surface of the housing 620 with the surface of the middle plate portion 211.

[0107] Therefore, when the USB interface connector 600 is housed in the positioning groove 2111 on the middle plate 211, since the stop wall 62111 and the first limiting wall 201 (one side wall of the positioning groove 2111) are in surface contact, to ensure sufficient contact area between the stop wall 62111 and the first limiting wall 201, the positioning groove 2111 must have sufficient depth. This results in a larger portion of the USB interface connector 600 within the positioning groove 2111, and a smaller portion protruding above the middle plate 211. Consequently, the USB interface connector 600 occupies less space in the receiving cavity, which is beneficial for the layout design of components within the cavity. Furthermore, for the thinner Type-C interface, the USB interface connector 600 itself occupies less thickness space, allowing for a smaller groove depth in the positioning groove 2111, thereby reducing the thickness of the middle plate 211 and the overall thickness of the middle frame 210, which is more conducive to the overall thinning and lightening of the electronic device 10.

[0108] Referring to Figures 10 and 11, the stop portion 6211 disposed at the first end of the housing 620 of the USB interface connector 600 may further include a guide wall 62112, which is connected to the second end of the stop wall 62111. That is, the guide wall 62112 is connected to the end of the stop wall 62111 extending towards the middle plate portion 211, and extends from the stop wall 62111 towards the middle plate portion 211. Furthermore, the guide wall 62112 extends away from the first limiting wall 201, and from the end of the guide wall 62112 connected to the stop wall 62111 to the other end of the guide wall 62112, the distance between the guide wall 62112 and the first limiting wall 201 gradually increases.

[0109] By extending a guide wall 62112 from the second end of the stop wall 62111, when the USB interface connector 600 is installed onto the middle frame 210, the guide wall 62112 first contacts the first limiting wall 201 of the middle plate portion 211. The guide wall 62112 slides along the first limiting wall 201 so that the stop wall 62111 can smoothly abut against the first limiting wall 201, limiting the first end of the housing 620 of the USB interface connector 600 to the first limiting wall 201. Under the guiding action of the guide wall 62112, the stop portion 6211 of the housing 620 can be prevented from scraping against the first limiting wall 201 of the middle plate portion 211, and the USB interface connector 600 can be smoothly installed onto the middle frame 210, thus ensuring the installation reliability of the USB interface connector 600.

[0110] Based on this, the stop portion 6211 provided in the housing 620 of the USB interface connector 600 may further include a reinforcing wall 62113, which is connected to the side of the stop wall 62111. The reinforcing wall 62113 may extend from the stop wall 62111 towards the second end of the housing 620, but the reinforcing wall 62113 will not exceed the stop wall 62111 to avoid affecting the first limiting wall 201 of the stop wall 62111 abutting against the middle plate portion 211. Furthermore, the reinforcing wall 62113 increases the total surface area of ​​the stop portion 6211, enhances the structural strength of the stop portion 6211, and improves the impact resistance of the stop portion 6211. There is an included angle between the reinforcing wall 62113 and the stop wall 62111. The reinforcing wall 62113 can better decompose and offset the force on the stop wall 62111, help the stop wall 62111 resist deformation, and improve the reliability of the stop wall 62111.

[0111] The reinforcing wall 62113 can be provided only on one side of the stop wall 62111, or it can be provided on both sides of the stop wall 62111, further improving the structural strength and reliability of the stop portion 6211 and increasing its impact resistance. When the reinforcing wall 62113 is provided only on one side of the stop wall 62111, it can be located on the side of the stop portion 6211 facing away from the outer shell 620. For the stop portions 6211 located at both ends of the width direction of the outer shell 620, the reinforcing wall 62113 can be located on the side of the two stop portions 6211 facing away from each other. In this way, the reinforcing wall 62113 is closer to the edge of the outer shell 620, which can prevent the reinforcing wall 62113 from interfering with the electrical connection terminal 601 of the conductive core 610.

[0112] For example, in the stop portion 6211 provided in the housing 620 of the USB interface connector 600, the reinforcing wall 62113 can be perpendicular to the stop wall 62111, and the reinforcing wall 62113 can extend along the plane direction containing the extension direction (X direction shown in FIG. 5) and the height direction (Z direction shown in FIG. 5) of the housing 620. In this way, the force transmission direction between the stop wall 62111 and the first limiting wall 201 of the middle plate portion 211 is mainly concentrated in the plane direction of the reinforcing wall 62113. The force on the stop wall 62111 can be more fully transmitted to the reinforcing wall 62113, which has a better buffering and decomposition effect on the force on the stop wall 62111, which can improve the impact resistance of the stop wall 62111, and the stability and reliability of the stop wall 62111 are higher.

[0113] In this embodiment, the housing 620 of the USB interface connector 600 may also be provided with a claw portion 6212 (see Figure 8 or Figure 9), which extends toward the circuit board 300. The circuit board 300 has a mounting hole 310 (see Figure 7), the position of which corresponds to the position of the claw portion 6212, and the claw portion 6212 is inserted into the mounting hole 310 (see Figure 13). Thus, the USB interface connector 600 is not only encapsulated on the circuit board 300 via the power terminal 601, but also connected to the circuit board 300 via the claw portion 6212. By inserting the claw portion 6212 of the USB interface connector 600 into the mounting hole 310 of the circuit board 300, the USB interface connector 600 can be positioned on the circuit board 300, improving the assembly accuracy between the USB interface connector 600 and the circuit board 300, ensuring that the power terminal 601 of the USB interface connector 600 can be aligned with the power pad on the circuit board 300, and ensuring the reliability of the electrical connection between the two.

[0114] It should be noted that, since the circuit board 300 needs to connect to the power terminal 601 on the conductive core 610 of the USB interface connector 600, and the conductive core 610 is located inside the housing 620, the power terminal 601 of the conductive core 610 is generally located within the height space of the housing 620, and there is a gap between the power terminal 601 of the conductive core 610 and the surface of the housing 620 facing the circuit board 300. Therefore, the circuit board 300 typically needs to avoid the housing 620 when connecting to the conductive core 610. The circuit board 300 does not cover the top surface of the housing 620 (the surface of the housing 620 facing the circuit board 300).

[0115] Therefore, in order for the USB interface connector 600 to connect with the circuit board 300 via the claw portion 6212, the claw portion 6212 can be positioned at both ends of the housing 620 in the width direction, and the claw portion 6212 can be located in the middle area of ​​the housing 620 in the height direction. In this way, the claw portion 6212 does not occupy the area directly in front of the first end of the housing 620, avoiding the power receiving end 601 of the conductive core 610, and does not affect the connection between the circuit board 300 and the power receiving end 601 of the conductive core 610. Furthermore, the claw portion 6212 is not located on the top surface of the housing 620, and avoids areas not covered by the circuit board 300, facilitating the mating of the claw portion 6212 and the circuit board 300.

[0116] Correspondingly, the circuit board 300 can be designed with a U-shaped structure (see Figure 7). The circuit board 300 has a clearance notch 320 on the top surface of the housing 620 of the USB interface connector 600, allowing the housing 620 of the USB interface connector 600 to partially pass through the clearance notch 320, thus enabling the conductive core 610's contact terminal 601 to mate with the circuit board 300. Furthermore, the sides of the circuit board 300 cover both ends of the housing 620 of the USB interface connector 600 in the width direction, allowing mounting holes 310 to be provided on both sides of the circuit board 300, so that the mounting holes 310 on the circuit board 300 correspond to the claw portions 6212 of the USB interface connector 600.

[0117] The claw portion 6212 of the USB interface connector 600 can also be fixedly connected to the mounting hole 310 on the circuit board 300, for example, the claw portion 6212 is soldered or glued to the mounting hole 310. When the USB interface connector 600 is only encapsulated on the circuit board 300 through the power terminal 601, due to the weight of the USB interface connector 600 itself, the USB interface connector 600 may fall into the clearance notch 320 of the circuit board 300 on the side where the second end of the outer shell 620 is located, while the USB interface connector 600 on the side where the first end of the outer shell 620 is located may exhibit a lifting phenomenon, causing the power terminal 601 of the conductive core 610 to be loosely connected to the circuit board 300 or even unable to be reliably connected. However, in this embodiment, by fixing the USB interface connector 600 to the circuit board 300 through the claw portion 6212, the connection strength between the USB interface connector 600 and the circuit board 300 can be further increased, the USB interface connector 600 is connected stably, and the connection reliability between the power terminal 601 of the conductive core 610 and the circuit board 300 can be enhanced. In addition, both ends of the housing 620 are connected to the circuit board 300 via the claw portion 6212, and the USB interface connector 600 is balanced with the circuit board 300, resulting in high connection reliability.

[0118] Figure 14 is an exploded structural view of the housing of the USB interface connector in Figure 8. Referring to Figure 14, considering the processing difficulty and sealing performance of the housing 620 of the USB interface connector 600, this embodiment of the application designs the housing 620 as a separate unit. The housing 620 may include an outer frame 621 and an inner frame 622. The inner frame 622 is disposed within the outer frame 621 and surrounds the outer periphery of the conductive core 610. Both the inner frame 622 and the outer frame 621 can be metal frames to ensure the overall structural strength of the housing 620. For example, both the inner frame 622 and the outer frame 621 are made of stainless steel.

[0119] With this configuration, the stop portion 6211 that needs to cooperate with the middle frame 210 and the claw portion 6212 that needs to cooperate with the circuit board 300 can both be located on the outer frame 621. In this way, the stop portion 6211 and the claw portion 6212 on the outer frame 621 are located on the outermost side of the outer shell 620, which facilitates the stop portion 6211 to extend towards the middle plate portion 211 and the claw portion 6212 to extend towards the circuit board 300.

[0120] Furthermore, the inner frame 622 can be configured as a one-piece ring-shaped frame, with one end of the inner frame 622 extending beyond the corresponding end of the outer frame 621 towards the edge portion 212 of the middle frame 210. This end of the inner frame 622 serves as the second end of the outer shell 620. In this way, the USB interface connector 600 can abut against the second limiting wall 202 (e.g., the inner sidewall of the edge portion 212) of the middle frame 210 through the second end of the inner frame 622. The seamless end face of the second end of the one-piece inner frame 622 can better achieve a sealed connection between the outer shell 620 and the middle frame 210, preventing external moisture and dust from entering the electronic device 10 through the gap between the insertion hole 2121 and the inner frame 622, thereby improving the sealing performance of the electronic device 10.

[0121] The inner frame 622 may have a sealing element 630 at its second end. The sealing element 630 is pressed between the inner frame 622 and the second limiting wall 202 of the middle frame 210 (see Figure 11 or Figure 12). The sealing element 630 is in close contact with both the inner frame 622 and the second limiting wall 202. The sealing element 630 seals the gap between the inner frame 622 and the middle frame 210, achieving a sealed connection between the USB interface connector 600 and the middle frame 210. For example, the sealing element 630 can be UV (Ultraviolet Rays) adhesive applied to the inner frame 622.

[0122] Referring again to Figure 14, both the stop portion 6211 and the claw portion 6212 are disposed on the outer frame 621. Furthermore, this embodiment further incorporates a split design for the outer frame 621. The outer frame 621 may include a first frame 6213 and a second frame 6214. The first frame 6213 is located on the side of the outer shell 620 near the middle plate portion 211, and the second frame 6214 is located on the side of the outer shell 620 near the circuit board 300. The first frame 6213 and the second frame 6214 are joined together along the height direction of the outer shell 620 to form the outer frame 621. The stop portion 6211 may be disposed on the first frame 6213, and the claw portion 6212 may be disposed on the second frame 6214.

[0123] Since the first frame 6213 is close to the middle plate portion 211 of the middle frame 210, by providing the stop portion 6211 to the first frame 6213, it is easy to extend the stop portion 6211 toward the middle plate portion 211 without interfering with the second frame 6214. Similarly, since the second frame 6214 is close to the circuit board 300, by providing the claw portion 6212 to the second frame 6214, it is easy to extend the claw portion 6212 toward the circuit board 300 without interfering with the first frame 6213.

[0124] Specifically, both the first frame 6213 and the second frame 6214 may include a main body 6215 and a mating portion 6216, with the mating portion 6216 located at both ends of the extending direction of the main body 6215. Both the main body 6215 of the first frame 6213 and the main body 6215 of the second frame 6214 can be semi-annular structures, forming an accommodating space. The conductive core 610 and the inner frame 622 sleeved around the conductive core 610 pass through this accommodating space. The mating portions 6216 of the first frame 6213 and the second frame 6214 are fitted together. For example, the mating portions 6216 of the first frame 6213 and the second frame 6214 are welded, bonded, or connected by fasteners to fix the first frame 6213 and the second frame 6214.

[0125] The stop portion 6211 can be disposed on the mating portion 6216 of the first frame 6213, and the stop portion 6211 extends and folds over from the mating portion 6216 of the first frame 6213 toward the middle plate portion 211. The claw portion 6212 can be disposed on the mating portion 6216 of the second frame 6214, and the claw portion 6212 extends and folds over from the mating portion 6216 of the second frame 6214 toward the circuit board 300. In this way, it is convenient for the stop portion 6211 to abut against the first limiting wall 201 on the middle plate portion 211, and it is also convenient for the claw portion 6212 to be inserted into the circuit board 300. At the same time, it does not affect the fit and connection between the mating portion 6216 of the first frame 6213 and the mating portion 6216 of the second frame 6214.

[0126] Furthermore, the stop portion 6211 can be integrally formed onto the outer frame 621, and the first frame 6213 can also be a one-piece molded part. For example, the first frame 6213 can be formed by stamping, or it can also be formed by metal injection molding (MIM). Similarly, the claw portion 6212 can also be integrally formed onto the outer frame 621, and the second frame 6214 can also be a one-piece molded part. For example, the second frame 6214 can be formed by stamping, or the first frame 6213 can also be formed by metal injection molding. In this way, the manufacturing process of the first frame 6213 and the second frame 6214 is simpler and more efficient, and the integrity and consistency of the first frame 6213 and the second frame 6214 are better. The structural strength of the first frame 6213 and the second frame 6214 is also higher, and the outer frame 621 formed by the two is more reliable and has a longer service life.

[0127] Figure 15 is a schematic diagram of the inner frame provided in an embodiment of this application. Referring to Figure 15, the inner frame 622 may include a main frame 6221 and a flange 6222. The flange 6222 is located at the second end of the main frame 6221 (the end of the main frame 6221 facing outwards from the housing 200 of the electronic device 10). The main frame 6221 is the main structure of the inner frame 622, and the two axial ends of the main frame 6221 are the two axial ends of the inner frame 622. The flange 6222 is folded outwards at the second end of the main frame 6221. The inner frame 622 abuts against the second limiting wall 202 (e.g., the inner sidewall of the side frame 212) of the middle frame 210 by means of the flange 6222. The sealing member 630 is disposed between the flange 6222 and the second limiting wall 202.

[0128] Compared to related technologies that design the inner frame as a straight cylinder and connect (e.g., weld) a separate stop ring to the outer wall of the straight cylindrical inner frame, relying on the stop ring to abut against the second limiting wall 202 of the middle frame 210, this design typically involves assembling the stop ring onto the outer wall of the inner frame using a jig, resulting in assembly tolerances. Furthermore, the stop ring is subjected to high temperatures during welding to the inner frame, and its position may change. This leads to a larger positional error in the stop ring, affecting the parallelism between the stop ring and the second limiting wall 202. Consequently, the sealing ring / sealing adhesive cannot be tightly compressed between the stop ring and the second limiting wall 202, increasing the overall protection risk of the electronic device 10.

[0129] In this embodiment, by integrally molding the flange 6222 onto the second end of the main frame 6221, the inner frame 622 becomes a single-piece component. This reduces the assembly steps of the USB interface connector 600, improving its assembly efficiency. Furthermore, since there are no assembly tolerance issues, the flange 6222 has high positional accuracy, precisely providing the mounting position for the seal 630. This ensures that the seal 630 tightly seals the gap between the inner frame 622 and the housing 200 of the electronic device 10, improving the overall sealing performance of the electronic device 10.

[0130] For example, the inner frame 622 can be formed by stamping, deep drawing or metal injection molding.

[0131] Referring again to Figure 15, the flange 6222 may include a first segment 62221 and a second segment 62222, which extend sequentially from the second end of the main frame 6221. The first segment 62221 extends inward toward the housing 200, while the second segment 62222 extends away from the main frame 6221. Thus, the second segment 62222 forms a mounting surface for the second limiting wall 202 facing the housing 200. This mounting surface can be used to receive the seal 630, allowing the second segment 62222 of the flange 6222 to compress the seal 630. The first segment 62221, located between the main frame 6221 and the second segment 62222, supports the second segment 62222. Forces acting on the second segment 62222 can be transmitted to the main frame 6221 through the first segment 62221, enhancing the structural strength and reliability of the flange 6222.

[0132] The first segment 62221 of the flange 6222 can extend in the opposite direction parallel to the side wall of the main frame 6221, and can fit against the outer wall of the main frame 6221 (see Figure 11). Thus, the first segment 62221 is entirely supported by the outer wall of the main frame 6221, allowing for more efficient force transfer between the first segment 62221 and the main frame 6221. The flange 6222 provides better overall support and stronger resistance to deformation, enabling reliable and durable compression sealing of the seal 630, thereby improving the overall sealing performance of the electronic device 10.

[0133] The second segment 62222 of the flanged portion 6222 can extend along a direction perpendicular to the side wall of the main frame 6221, and the second segment 62222 can be parallel to the first segment 62221 (see Figure 11). In this way, the second segment 62222 can remain parallel to the second limiting wall 202, ensuring that the seal 630 can fit tightly between the second segment 62222 and the second limiting wall 202. Furthermore, the second segment 62222 has a more balanced overall force distribution, stronger resistance to deformation, and higher stability and reliability.

[0134] Figure 16 is a schematic diagram of the conductive core provided in an embodiment of this application. Figure 17 is an exploded structural view of the conductive core in Figure 16. Referring to Figures 16 and 17, the conductive core 610 of the USB interface connector 600 may include a main core 611 and a protective frame 612. The main core 611 is used to transmit signals and realize the function of the USB interface connector 600. The protective frame 612 is sleeved on the outer periphery of the main core 611 to protect the main core 611 and enhance the integrity and reliability of the conductive core 610.

[0135] In the USB interface connector 600, in its extension direction (the insertion direction of the USB interface connector head), a protective frame 612 is fitted over the middle portion of the main core 611, with both ends of the main core 611 exposed outside the protective frame 612. One end of the main core 611 exposed outside the protective frame 612 is the electrical connection terminal 601 of the conductive core 610, and the other end is the insertion terminal 602 of the conductive core 610. Furthermore, the outer wall surface of the protective frame 612 contacts the inner wall surface of the outer shell 620, and the outer wall surface of the protective frame 612 and the inner wall surface of the outer shell 620 (i.e., the inner wall surface of the inner frame 622) can be welded or bonded together to achieve the assembly of the conductive core 610 and the outer shell 620. Additionally, the protective frame 612 can be a metal sleeve to provide sufficient rigidity and improve the reliability of the conductive core 610.

[0136] Referring again to Figures 16 and 17, in this embodiment, the protective frame 612 may include a base portion 6121 and an extension portion 6122, with the extension portion 6122 connected to the side of the base portion 6121 facing outwards from the housing 200. That is, the base portion 6121 is located on the side of the protective frame 612 near the power connection terminal 601 of the main core 611, while the extension portion 6122 is located on the side of the protective frame 612 near the insertion terminal 602 of the main core 611. Along the height direction of the USB interface connector 600, the height of the base portion 6121 is greater than the height of the extension portion 6122, forming a step between the base portion 6121 and the extension portion 6122.

[0137] The height of the base portion 6121 of the protective frame 612 matches the inner height of the outer shell 620 (the distance between the inner walls of opposite sides of the outer shell 620 in the height direction). The base portion 6121 is attached to the inner wall of the inner frame 622 to position the conductive core 610 within the outer shell 620. The height of the extension portion 6122 of the protective frame 612 can be less than the inner height of the outer shell 620, and there can be gaps between the two side surfaces of the extension portion 6122 and the two side inner surfaces of the outer shell 620. Correspondingly, the thickness of the main core 611 can be differentiated by region. The main core 611 is thicker in the portion covered by the base portion 6121, allowing its outer surface to fit tightly against the inner wall of the base portion 6121. The main core 611 is thinner in the portion covered by the extension portion 6122, allowing its outer surface to also fit tightly against the inner wall of the extension portion 6122.

[0138] Based on this, in the height direction of the USB interface connector 600, the extension 6122 of the protective frame 612 is located in the central region of the base 6121 of the protective frame 612. Alternatively, the centerline of the protective frame 612 and the centerline of the base 6121 of the protective frame 612 are on the same straight line, which is the height centerline of the USB interface connector 600. Therefore, the distance between the top surface of the extension 6122 (the outer surface of the extension 6122 facing the circuit board 300) and the inner top wall of the inner frame 622 (the inner wall of the inner frame 622 facing the circuit board 300) is equal to the distance between the bottom surface of the extension 6122 (the outer surface of the extension 6122 facing the middle plate 211) and the inner bottom wall of the inner frame 622 (the inner wall of the inner frame 622 facing the middle plate 211).

[0139] This configuration, using the extension 6122 of the protective frame 612 to position the main core 611, ensures the centering of the insertion end 602 of the main core 611 in the height direction of the USB interface connector 600. This improves the positional accuracy of the main core 611, ensuring reliable insertion between the USB interface connector and the USB interface connector 600, and achieving stable and continuous signal transmission. Furthermore, as long as the base 6121 of the protective frame 612 reliably fits against the inner wall of the housing 620, the extension length of the base 6121 is not required. Correspondingly, the length of the portion of the main core 611 covered by the base 6121 is also not required. This reduces the overall length of the conductive core 610, which is beneficial for the miniaturization of the USB interface device. It also reduces the space occupied by the USB interface connector 600 within the housing 200's receiving cavity, facilitating the layout design of other components within the receiving cavity.

[0140] Figure 18 is a schematic diagram of the structure of the main core 611 after removing part of the plastic body according to an embodiment of this application. Referring to Figures 17 and 18, regarding the structural design of the main core 611, the main core 611 typically includes multiple conductive terminals 6111 and a plastic body 6112 enclosing these conductive terminals 6111. The conductive terminals 6111 are typically made of metal and are used for signal transmission. By enclosing each conductive terminal 6111 with the plastic body 6112, the plastic body 6112 can fix and protect the conductive terminals 6111, forming an integral main core 611. The plastic body 6112 can fix the conductive terminals 6111 in a spaced-apart state, ensuring that the main core 611 can reliably transmit signals and avoiding the risk of short circuits in the main core 611.

[0141] The conductive terminals 6111 provided in the main core 611 typically include a ground terminal 61111 (equivalent to the negative terminal), a voltage terminal 61112 (equivalent to the positive terminal), and a signal terminal 61113 for transmitting data signals. Taking a Type-C interface connector as an example, the conductive terminals 6111 in the main core 611 have a double-sided symmetrical design. Two rows of conductive terminals 6111 are symmetrically arranged in the main core 611. The ground terminal 61111, voltage terminal 61112, and signal terminal 61113 are symmetrically arranged on both the front side (the surface facing the circuit board 300) and the back side (the surface facing the middle plate 211). Furthermore, an isolation plate 6113 is usually provided between the two rows of conductive terminals 6111 to electrically isolate the two rows of conductive terminals 6111.

[0142] Figure 18 illustrates a 16-pin Type-C interface connector. Both ends of the main core 611 have grounding terminals 61111. Adjacent to the grounding terminals 61111 are voltage terminals 61112. Four signal terminals 61113 are arranged between the two voltage terminals 61112 in each row of power terminals 601. Thus, there are a total of four grounding terminals 61111, four voltage terminals 61112, and eight signal terminals 61113 on both sides, for a total of 16 conductive terminals 6111. Of course, the isolation plate 6113 located between the two rows of conductive terminals 6111 can also be grounded. A grounding pin needs to be led out from the isolation plate 6113, and this grounding pin is connected to the circuit board 300 along with each conductive terminal 6111. For example, a grounding pin can be led out from one end of the isolation plate 6113, or from both opposite ends of the isolation plate 6113.

[0143] Compared to the 24-pin Type-C connector, the 16-pin Type-C connector provides space for four conductive terminals 6111 on both sides of the main core 611. This allows for two additional conductive terminals 6111 between the ground terminals 61111 and the adjacent voltage terminals 61112 on both sides of the main core 611. This increases the spacing between the voltage terminals 61112 and the ground terminals 61111, enhancing the electrical isolation reliability of the voltage terminals 61112 and the ground terminals 61111, reducing the short-circuit risk of the USB connector 600, and improving the overall reliability of the USB connector 600.

[0144] Additionally, as one implementation, the protective frame 612 fitted over the main core 611 may also be designed with a notch 6123, located at the end of the protective frame 612 facing outwards from the housing 200. In other words, the notch 6123 is provided at the end of the protective frame 612 facing the insertion end 602 of the main core 611 (see Figure 16). Specifically, the notch 6123 may be provided at the end of the extension 6122 of the protective frame 612 away from the base portion 6121. Notches 6123 are provided on both opposite sidewalls in the height direction of the protective frame 612, and the notches 6123 on the two sidewalls of the protective frame 612 may, for example, be symmetrical to each other. Furthermore, the voltage terminals 61112 on both sides of the main core 611 are located within the coverage area of ​​the corresponding notch 6123.

[0145] It should be noted that within the portion of the main core 611 where the plug-in end 602 is located, the conductive terminals 6111 are exposed on both sides of the main core 611. When the main core 611 is plugged into the USB interface connector, the conductive terminals 6111 exposed on the surface of the main core 611 make electrical contact with the USB interface connector. Similarly, within the portion of the main core 6111 where the power receiving end 601 is located, the conductive terminals 6111 are also exposed outside the plastic body 6112 to facilitate electrical contact between the conductive terminals 6111 and the circuit board 300. The middle portion of the conductive terminals 6111 is completely enclosed within the plastic body 6112 to electrically isolate the conductive terminals 6111 and the protective frame 612. The conductive terminal 6111, which is exposed on the surface of the main core 611 and serves as the plug-in end 602, can be a certain distance from the end of the protective frame 612 facing the plug-in end 602 of the main core 611, to ensure that the conductive terminal 6111 does not make contact with the protective frame 612.

[0146] A notch 6123 is formed at one end of the protective frame 612 facing the insertion end 602 of the main core 611, and the notch 6123 is recessed at the other end of the protective frame 612. Within the coverage area of ​​the notch 6123, the conductive terminal 6111, which is exposed on the surface of the main core 611 and serves as the insertion end 602, is further away from the end of the protective frame 612 facing the insertion end 602 of the main core 611. Thus, the notch 6123 increases the distance between the conductive terminal 6111 and the end face of the protective frame 612, reducing the short-circuit risk of the conductive core 610 and enhancing the reliability of signal transmission by the conductive core 610. Furthermore, the larger the distance between the conductive terminal 6111 and the end face of the protective frame 612, the longer the flow path of liquid between the conductive terminal 6111 and the protective frame 612 when liquid ingress occurs in the electronic device 10, further reducing the short-circuit risk between the conductive terminal 6111 and the protective frame 612.

[0147] With voltage terminal 61112 located within the coverage area of ​​notch 6123, the distance between voltage terminal 61112 and the end face of protective frame 612 is increased, reducing the short-circuit risk of voltage terminal 61112. This allows the USB interface connector 600 to transmit voltage signals more stably and reliably, resulting in higher operational reliability. Furthermore, when all signal terminals 61113 are located between the voltage terminals 61112 on both sides, notch 6123 covers the voltage terminals 61112, meaning it can cover all signal terminals 61113. Notch 6123 enables all signal terminals 61113 to transmit data signals more reliably, ensuring stable operation of the USB interface connector 600.

[0148] Additionally, for the 16-pin Type-C connector, there is ample space between the voltage terminal 61112 and the ground terminal 61111 for two conductive terminals 6111. Therefore, there is sufficient space on the end face of the protective frame 612 to create the notch 6123. Even if the notch 6123 extends to cover the voltage terminals 61112 on both sides, there can still be a certain distance between the notch 6123 and the two side edges of the protective frame 612.
