An embodiment of the present application provides a terminal device, which may be a mobile phone, a tablet computer, a personal digital assistant (personal digital assistant, PDA), a vehicle-mounted computer, and other electronic devices integrated with components such as a USB interface. The embodiment of the present application does not limit the specific form of the foregoing electronic device. As shown in FIG. 1 , for the convenience of description, the terminal device is a mobile phone as an example for description below.

In order to clearly describe the subsequent structural features and the positional relationship of the structural features, the positional relationship of the various structures in the mobile phone is specified in the X-axis direction, the Y-axis direction and the Z-axis direction. Wherein, as shown in FIG. 2 , the X-axis direction is the width direction of the mobile phone, the Y-axis direction is the length direction of the mobile phone, and the Z-axis direction is the thickness direction of the mobile phone.

As shown in FIG. 1 , a mobile phone 100 includes a display screen 10 , a middle frame 20 and a rear case (not shown). The display screen 10 , the middle frame 20 and the rear case can form an accommodating cavity. Various electronic devices, such as circuit boards, batteries, USB devices, etc., can be installed in the accommodating cavity, and these electronic devices are generally fixed on the middle frame 20 or fixed by the middle frame 20 . The middle frame 20 and the rear shell can adopt various suitable shapes and structures according to needs, which are not specifically limited here.

As shown in FIG. 2 , a circuit board is installed on the middle frame 20 . Exemplarily, the circuit board includes a main board 21 and a sub board (or small board) 22 . The main chips of the mobile phone 100 are arranged on the motherboard 21 , such as SOC (system on chip), memory chip, camera chip and so on. The sub-board (or small board) 22 is provided with other chips or electronic devices required by the mobile phone, such as a display chip or a power management chip. The main board 21 and the sub-board 22 can be electrically connected and communicated through connectors such as cables.

A USB interface 23 is installed on the sub-board 22 . The USB interface 23 is, for example, a Type-C USB interface, which is used to connect with the external USB data cable 40, so that the mobile phone 100 can be electrically connected or communicated with an external charger or other terminals, so as to perform charging or perform data interaction with external devices.

As shown in Figures 1 and 3, an opening 30 is also provided on the middle frame 20, and the USB interface 23 extends the pins of the USB interface 23 from the accommodating cavity to the outside of the cavity through the opening 30, so as to be able to communicate with the external USB The data line 40 is connected. The cross section of the opening 30 is, for example, a rectangle in the middle plus semicircles at both ends. The cross-sectional shape of the opening 30 is the shape of a plane taken along a sectional plane perpendicular to the longitudinal direction Y of the mobile phone.

For an electronic device with a waterproof function, the USB interface 23 must meet certain waterproof requirements, that is, the opening 30 must meet certain waterproof requirements. As shown in FIG. 3 , a waterproof structure is generally added to the middle frame 20 and the USB interface 23 at the position B (also called the sealing position) at the junction of the opening 30 and the receiving cavity, so that the USB interface 23 meets the waterproof requirements, and Prevent external moisture from entering the interior of the mobile phone 100 (that is, the housing cavity) through the opening 30 , causing damage to the electronic devices inside the mobile phone 100 .

The waterproof structure of the middle frame 20 and the USB interface 23 of the mobile phone 100 at the sealing position will be described in detail below with reference to FIG. 4 and FIG. 5 .

At present, the waterproof structure of the middle frame 20 and the USB interface 23 of the mobile phone 100 at the sealing position B is a Y-direction sealing structure. In the first way, as shown in Figure 4, a sealing feature is formed at the sealing position B on the middle frame 20, such as a step structure, a groove structure or other structures, and a sealing soft glue 231 is formed on the USB interface 23, the sealing soft glue 231 may be formed on the USB interface 23 by dispensing glue or the like. When the USB interface 23 is inserted into the opening 30, the soft sealing glue 231 forms an interference fit with the sealing feature of the middle frame, so that the USB interface 23 and the opening 30 are sealed at the sealing position B, providing a sealed environment for the internal cavity . And in order to form an interference fit between the sealing soft glue 231 and the sealing feature of the middle frame 20, the positioning features are formed at the C1 and D2 positions of the middle frame 20, and the limiting features are formed at the C2 and D2 positions of the USB interface 23. When the After the USB interface 23 is inserted into the opening 30 , the positioning features and limit features at the positions of C1 and C2 and D1 and D2 will provide a force in the Y direction so that the sealing rubber 231 forms an interference fit with the sealing features of the middle frame 20 . The matching manner of the positioning features and limit features at positions C1 and C2 and D1 and D2 can refer to the corresponding features at positions C and D in FIG. 5 . This method of implementing interference fit through Y-direction force to achieve sealing is referred to as Y-direction sealing herein.

Although this method can make the USB interface 23 and the opening 30 be sealed at the sealing position B, because the USB interface 23 needs to be welded to the sub-board 22 first during the assembly process, and the sub-board 22 is huge in size compared to the USB interface 23, Therefore, in the process of inserting the USB interface 23 into the opening 30, only an oblique insertion method can be used, and due to the existence of the above-mentioned positioning features and limit features, it is very inconvenient to install the USB interface 23 or remove the USB interface 23, and it is easy to damage. cause damage to some areas. Moreover, with the requirement of thinner and lighter mobile phones, setting positioning features on the middle frame will bring more difficulties to the layout and installation of circuit boards and components inside the mobile phone.

The second method is as shown in FIG. 5 , at the sealing position B, a sealing foam 232 is pasted between the middle frame 20 and the USB interface 23 to realize sealing, so as to provide a sealed environment for the internal cavity. And similar to that shown in FIG. 4 , positioning features and limiting features are respectively formed on the middle frame 20 and the USB interface 23 at positions C and D. When the USB interface 23 is inserted into the opening 30, the positioning features at positions C and D The and limiting feature will provide a Y-direction force, so that the sealing foam 232 can fit more firmly at the sealing position B, thereby achieving a better sealing effect between the USB interface 23 and the opening 30 at the sealing position B. In addition, in order to facilitate the installation of the USB interface 23 into the opening 30 of the middle frame 20, the USB interface 23 is first welded together with the flexible circuit board 233, and after the USB interface 23 is installed in the opening 30 of the middle frame 20, the The flexible circuit board 233 is connected to the main board 21 or the sub-board 22 . In this way, since there is no need to weld the USB interface 23 on the sub-board 22 first, the installation of the USB interface 23 is relatively easy because it is not fixed with the sub-board 22 during the installation of the USB interface 23 . However, due to the existence of the above-mentioned limiting features and positioning features, this sealing method still has the problem of difficult disassembly, and the requirements of the above-mentioned positioning features and limiting features lead to cumbersome manufacturing processes for the middle frame 20 and USB interface 23, and will occupy the mobile phone. The internal space of the mobile phone is not good for the thinning and lightening of the mobile phone.

The embodiment of the present application provides a sealing structure for a USB interface based on the above description, which makes the installation and removal of the USB interface easier, and can reduce the occupation of internal space, which is conducive to the thinner and lighter requirements of the mobile phone.

As shown in Figure 6, an elastic sealing ring 234 is provided at the position corresponding to the USB interface 23 and the sealing position B. The size of the elastic sealing ring 234 is larger than that of the USB interface 23 and inserted into the opening 30. After the middle frame 20 and the USB interface 23 are at the sealing position The gap at B, therefore, when the USB interface 23 is inserted into the opening 30 , at the sealing position B, the middle frame 20 and the elastic sealing ring 234 will squeeze each other in the Z direction, thereby achieving sealing. Since this sealing method achieves sealing through the force in the Z direction, it is called Z-direction sealing in this article. Compared with the Y-direction seal shown in Figure 4 and Figure 5, the Z-direction seal does not require Y force, so there is no need to make positioning features and limit features on the middle frame 20 and USB interface 23, as shown in the dotted line area in Figure 6 As shown, there are no positioning features and limit features shown in FIG. 4 and FIG. 5 on the middle frame 20 and the USB interface 23 . This not only makes the installation and disassembly of the USB interface 23 easier, but also greatly reduces the manufacturing complexity of the middle frame 20 and the USB interface 23, reduces the cost, and reduces the occupation of the internal space of the mobile phone 100, which is conducive to further thinning of the mobile phone. change.

Similar to that shown in FIG. 5 , in the solution shown in FIG. 6 , in order to facilitate the installation of the USB interface 23 into the opening 30 of the middle frame 20 , the USB interface 23 is first welded together with the flexible circuit board 233 . After the flexible circuit board 233 is installed in the opening 30 of the middle frame 20, the flexible circuit board 233 is connected to the main board 21 or the sub-board 22. In this way, since there is no need to weld the USB interface 23 on the sub-board 22 first, the installation of the USB interface 23 is relatively easy because it is not fixed with the sub-board 22 during the installation process of the USB interface 23 . And because of the existence of the flexible circuit board 233, the USB interface 23 can be directly connected and communicated with the chip (such as SOC) on the main board 21 through the flexible circuit board 233 as required, without first being connected to the sub-board 22, and then through the sub-board 22. The board 22 communicates with chips on the motherboard 21 .

It should be understood that although the USB interface 23 can directly connect and communicate with the chip on the motherboard 21 through the flexible circuit board 233, this is not necessary. In other embodiments, the USB interface 23 can still be It is also feasible to communicate with the sub-board 22 first, and then communicate with the chips on the main board 21 through the sub-board 22 .

As shown in Figure 7, an elastic sealing ring 234 is provided at the position corresponding to the USB interface 23 and the sealing position B. The size of the elastic sealing ring 234 is larger than that of the USB interface 23 and inserted into the opening 30. After the middle frame 20 and the USB interface 23 are in the sealing position The gap at B, therefore, when the USB interface 23 is inserted into the opening 30 , at the sealing position B, the middle frame 20 and the elastic sealing ring 234 will squeeze each other in the Z direction, thereby achieving sealing. Since this sealing method achieves sealing through the force in the Z direction, it is called Z-direction sealing in this article. Compared with the Y-direction seal shown in Figures 4 and 5, the Z-direction seal does not require Y force, so there is no need to make positioning features and limit features on the middle frame 20 and USB interface 23, as shown in the dotted line area in Figure 7 As shown, there are no positioning features and limit features shown in FIG. 4 and FIG. 5 on the middle frame 20 and the USB interface 23 . This not only makes the installation and disassembly of the USB interface 23 easier, but also greatly reduces the manufacturing complexity of the middle frame 20 and the USB interface 23, reduces the cost, and reduces the occupation of the internal space of the mobile phone 100, which is conducive to further thinning of the mobile phone. change.

Different from that shown in FIG. 6, in the solution shown in FIG. 7, the USB interface 23 is connected to the sub-board 22. However, since there are no positioning features and limitations shown in FIGS. Therefore, even if the USB interface 23 is connected to the sub-board 22 first, it can be easily installed into the opening 30 by inserting it obliquely during installation.

It should be understood that the specific structures of the middle frame 20 and the USB interface 23 shown in FIG. 6 and FIG. 7 do not limit the present application, and are only exemplary. The core of this application is to adopt Z-direction sealing between the USB interface 23 and the middle frame 20, so that there is no need to make positioning features and limit features on the middle frame 20 and the USB interface 23, not only the USB interface can be easily installed and disassembled, but also The manufacturing complexity of the middle frame 20 and the USB interface 23 is greatly reduced, the cost is reduced, and the occupation of the internal space of the mobile phone 100 is reduced, which is conducive to further thinning and thinning of the mobile phone.
