Description

Shielding covers and electronic equipment

[0001] This application claims priority to Chinese Patent Application No. 202411525280.8, filed with the State Intellectual Property Office of China on October 29, 2024, entitled "Shielding Cover and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the technical field of electronic equipment, and particularly relates to a shielding cover and an electronic device. Background Technology

[0003] The electromagnetic waves generated by board-to-board (BTB) connectors during operation can cause electromagnetic interference to surrounding components, leading to performance degradation. For example, the BTB connector connecting the main camera to the motherboard is close to the mid-frame antenna and the main camera itself, posing a risk of interference with antenna and shooting performance due to the electromagnetic waves generated by the BTB connector. Therefore, it is necessary to install a shielding cover on the motherboard to isolate the BTB connector from electromagnetic interference. The BTB connector shielding cover typically consists of an interlocking base and a cover.

[0004] To mount the shielding cover's base onto the motherboard, the base is equipped with a pick-up section for use by a surface mount technology (SMT) pick-up nozzle, facilitating the transfer of the shielding cover's base onto the motherboard for mounting. Currently, after the shielding cover's base is mounted onto the motherboard, the position of the pick-up section means it needs to be pried off before the male connector of the BTB connector engages with the female connector. This damages the structure of the shielding cover's base, resulting in poor reliability of the shielding cover. Summary of the Invention

[0005] This application provides a shielding cover and an electronic device. The suction part of the shielding cover does not require material breaking, thereby improving the reliability of the shielding cover.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a shielding cover. The shielding cover includes a base and a cover. The base has a first opening on its bottom surface and a second opening communicating with the first opening on its top surface facing away from the bottom surface. The base includes a suction portion with its suction surface facing away from the bottom surface. The cover is used to detachably cover the base and cover the second opening. When the cover is on the base, the cover and the base enclose a shielding chamber. The shielding chamber is used to accommodate a female connector of a male-female connector extending through the first opening, and a male connector of a male-female connector extending through the second opening and engaging with the female connector. In a first direction, the orthographic projection of the suction portion does not overlap with the orthographic projection of the second opening. Furthermore, in a second direction, the orthographic projection of the suction portion does not overlap with the orthographic projection of the first opening. The first direction and the second direction are at least one of the vertical and extending directions of the suction surface, and the vertical and extending directions of the suction surface are perpendicular.

[0008] If the orthographic projection of the suction portion does not overlap with the orthographic projection of the second opening in the first direction, it indicates that the suction portion and the second opening are spaced apart in the direction perpendicular to the first direction.

[0009] When the first direction includes the vertical direction of the suction surface, the suction part and the second opening are spaced apart in the extending direction of the suction surface. Since the male connector extends into the shielding chamber through the second opening, the suction part is naturally spaced apart from the male connector in the extending direction of the suction surface. Thus, during the process of the male connector moving vertically along the suction surface to engage with the female connector, the suction part does not obstruct the movement of the male connector, thereby enabling the engagement of the male and female connectors. Therefore, the suction part in this embodiment does not require material breaking, solving reliability problems such as reduced flatness of the bottom surface, risk of poor soldering, material breaking burrs lifting the cover, poor flatness of the solder surface, and poor strength caused by material breaking.

[0010] When the first direction includes the extension direction of the suction surface, the suction part and the second opening are spaced apart in the vertical direction of the suction surface, that is, the suction part has a gap between the vertical direction of the suction surface and the second reference plane where the top surface is located. This gap can be adjusted as needed so that the suction part is spaced apart from the male seat in the vertical direction of the suction surface when the cover is placed on the base. In this way, during the process of the male seat moving vertically along the suction surface to engage with the female seat, the suction part will not obstruct the movement of the male seat because it is spaced apart from the male seat in the vertical direction of the suction surface, thereby achieving the engagement of the male seat and the female seat. Therefore, the suction part in this embodiment does not require material breaking, which solves the reliability problems caused by material breaking, such as reduced flatness of the bottom surface, risk of cold solder joint, material breaking burrs lifting the cover, poor flatness of the solder surface, and poor strength.

[0011] In the second direction, if the orthographic projection of the suction part does not overlap with the orthographic projection of the first opening, it indicates that the suction part and the first opening are spaced apart in the vertical direction of the second direction. When the second direction includes the vertical direction of the suction surface, the suction part and the first opening are spaced apart in the extending direction of the suction surface. Since the female base extends into the shielding chamber through the first opening, the suction part is naturally spaced apart from the female base in the extending direction of the suction surface. Thus, during the installation process where the base moves vertically along the suction surface to allow the female base to extend into the shielding chamber through the first opening, the suction part will not obstruct the movement of the base, thereby enabling the installation of the base. Therefore, in this embodiment, the suction part does not require material breaking, solving reliability problems such as reduced flatness of the bottom surface, risk of poor soldering, material breaking burrs lifting the cover, poor flatness of the solder surface, and poor strength caused by material breaking.

[0012] When the second direction includes the extension direction of the suction surface, the suction part and the first opening are spaced apart in the vertical direction of the suction surface, that is, the suction part has a gap between the vertical direction of the suction surface and the first reference plane where the bottom surface is located. This gap can be adjusted as needed so that the suction part is spaced apart from the female seat in the vertical direction of the suction surface when the cover is placed on the base. During the installation process where the base moves vertically along the suction surface to allow the female seat to extend into the shielding chamber through the first opening, the suction part, being spaced apart from the female seat in the vertical direction of the suction surface, will not obstruct the movement of the base, thus enabling the installation of the base. Therefore, the suction part in this embodiment does not require material breaking, solving reliability problems such as reduced flatness of the bottom surface, risk of poor soldering, material breaking burrs lifting the cover, poor flatness of the solder surface, and poor strength caused by material breaking.

[0013] In some embodiments of this application, the base includes a side frame. The side frame is located between the bottom surface and the top surface and has a first through hole. A first opening communicates with a second opening through the first through hole. A suction portion fixes the side frame.

[0014] This embodiment provides a specific implementation where a first opening on the bottom surface of the base and a second opening on the top surface communicate with each other. In this specific implementation, the suction part can be fixed to the side frame.

[0015] In some embodiments of this application, the side facing the wall of the first through hole is the inner side of the side frame. The suction portion extends from the side frame toward the inner side of the side frame, and the suction portion is spaced between the second reference plane where the top surface is located and the first reference plane where the bottom surface is located. In the extension direction of the suction surface, the suction portion does not overlap with the orthographic projection of the second opening and the first opening, respectively.

[0016] This embodiment provides a specific implementation in which the orthographic projection of the suction portion in the extension direction of the suction surface does not overlap with the orthographic projections of the second opening and the first opening, respectively. In this case, there is a gap between the suction portion and the second reference plane where the top surface is located, and the first reference plane where the bottom surface is located. This gap can be adjusted as needed so that the suction portion is vertically spaced from the male and female seats respectively in the suction surface when the cover is placed on the base. The implementation effect of this embodiment can be referred to the relevant description of the foregoing embodiment.

[0017] In some embodiments of this application, the side frame is constructed as a strip with a length greater than its width. The side frame has a long sidewall extending in the length direction. The suction portion extends from the long sidewall toward the inside of the long sidewall.

[0018] In this embodiment, since the long sidewall extends along the length of the side frame, the suction part can utilize the length advantage of the long sidewall to form a suction surface that meets the SMT suction requirements and whose length is significantly greater than its width. The smaller the width of the suction surface, the shorter the distance the suction part extends inward toward the long sidewall, the greater the distance between the suction part and the male / female connector, and the lower the risk of the suction part rubbing against the male / female connector.

[0019] In some embodiments of this application, the side frame includes a first long sidewall and a second long sidewall disposed opposite to each other, the second long sidewall being used to construct a cable tray opening. The suction portion extends from the first long sidewall toward the inner side of the first long sidewall.

[0020] In this embodiment, the suction portion extends from the first long side wall opposite the second long side wall toward the inside of the first long side wall. In this case, the FPC flexible flat cable passing through the cable tray of the second long side wall to the outside of the shield and the suction portion are located on opposite sides of the male connector, respectively. Friction between the suction portions of the FPC flexible flat cable is less likely to occur, thereby improving the electrical connection reliability of the FPC flexible flat cable.

[0021] In some embodiments of this application, the side frame has a top surface facing the cover. The base also includes a first plate portion. The first plate portion extends from the top surface of the side frame toward the inside of the side frame. The first plate portion includes a first plate surface and a second plate surface disposed opposite to each other, the second plate surface of the first plate portion forming a top surface. The first plate portion has a second through hole, the second through hole forming a second opening on the second plate surface of the first plate portion, communicating with the first through hole. Suction portions are spaced apart on the side facing the first plate surface of the first plate portion. In the vertical direction, the orthographic projection of the first plate portion does not overlap with the orthographic projection of the suction portion.

[0022] This embodiment provides a specific implementation of a base with a top surface and a second opening on the top surface communicating with a first through hole. In this specific implementation, the second surface of the first plate portion forms the top surface of the base. A suction portion is spaced between the first plate portion and the second plate portion, and spaced below the first plate portion, i.e., on the side facing the first plate portion. In order not to interfere with the SMT suction head's suction of the suction surface, the orthographic projection of the first plate portion and the orthographic projection of the suction portion do not overlap in the vertical direction of the suction surface, so that the orthographic projection of the suction surface along the vertical direction of the suction surface on the side facing the suction surface falls on the cover.

[0023] In some embodiments of this application, the first plate portion has a first long side plate portion corresponding to a first long side wall. The base has a first notch. The first notch penetrates the first long side plate portion and extends below the top surface of the first long side wall. The suction portion extends from the first long side wall along the bottom surface of the first notch to the inside of the first long side wall.

[0024] This embodiment provides a specific implementation scheme to ensure that the orthographic projection of the first plate portion in the vertical direction of the suction surface does not overlap with the orthographic projection of the suction portion. When the suction portion extends inside the first long side wall along the bottom surface of the first notch, since the first notch extends through the first long side plate portion in the vertical direction of the suction surface, the suction portion is directly opposite the opening formed by the first notch penetrating the first long side plate portion in the vertical direction of the suction surface. The first plate portion no longer has a blocking structure that can block the movement of the SMT suction head, thereby not interfering with the suction head's suction of the suction surface.

[0025] In some embodiments of this application, the first notch penetrates a portion of the first long side plate, so that the first long side wall has fastening holes distributed along the sides of the first notch in the length direction. The fastening holes are provided with fastening holes for inserting protrusions on the cover.

[0026] In this embodiment, because the first notch sinks down the first long sidewall, the portion of the first long sidewall at the bottom of the first notch does not meet the spacing requirements for the fastening holes. To provide fastening holes on the first long sidewall that engage with the protrusion of the cover, the first notch penetrates a portion of the first long sideplate and sinks down to the first long sidewall, so that the first long sidewall has fastening hole portions distributed along the sides of the first notch in the length direction of the side frame. In this case, the fastening holes can be provided on the fastening hole portions, corresponding to the protrusion of the cover, thereby reducing the risk of the cover becoming loose.

[0027] In some embodiments of this application, the first gap gradually narrows in the downward direction.

[0028] In this embodiment, the first notch gradually narrows in the downward direction, forming an inverted trapezoid, and the opening of the first notch is wider than its bottom. In this case, the snap-fit ​​holes distributed on the sides of the first notch become increasingly wider in the downward direction, providing more space for the snap-fit ​​holes. This allows the snap-fit ​​holes to move away from the corners between the two side walls, thereby increasing the distance between the snap-fit ​​holes and the corners between the two side walls, thus reducing the risk of excessive deformation of the snap-fit ​​holes during the base's processing.

[0029] In some embodiments of this application, the side facing the wall of the first through hole is the inner side of the side frame. The suction part extends from the top of the side frame towards the inner side of the side frame, the suction surface is located inside the top surface, and the second openings are arranged side by side on the side of the suction surface facing away from the side frame.

[0030] This embodiment provides a specific implementation in which the orthographic projection of the suction portion does not overlap with the orthographic projection of the second opening in the vertical direction of the suction surface, and in the extension direction of the suction surface, the orthographic projection of the suction portion does not overlap with the orthographic projection of the first opening.

[0031] In some embodiments of this application, the side frame is constructed as an elongated strip with a length greater than its width. The side frame has a short sidewall extending in the width direction. The suction portion extends from the top of the short sidewall toward the inside of the short sidewall.

[0032] It should be noted that when the suction part extends from the top of the short side wall towards the inside of the short side wall, the suction surface and the second opening of the suction part are distributed side by side in the length direction of the side frame, occupying more space in the length direction of the side frame. Therefore, the shield of this embodiment is suitable for electronic devices in which the male and female connectors and surrounding devices have sufficient spacing in the length direction of the side frame.

[0033] In some embodiments of this application, the base further includes a first plate portion. The first plate portion extends from the top surface of the side frame toward the inner side of the side frame. The first plate portion includes a first plate surface and a second plate surface disposed opposite to each other, with the top surface including the second plate surface of the first plate portion. The first plate portion has a second through hole, which forms a second opening on the second plate surface of the first plate portion, and communicates with the second plate surface of the first plate portion. The suction portion is the part of the first plate portion on the side of the second through hole near the short side wall.

[0034] In some embodiments of this application, the side frame has an outer wall surface facing away from the wall of the first through hole, and the side facing the outer wall surface of the side frame is the outer side of the side frame. The suction portion extends from the side frame to the outer side of the side frame. When the cover is placed on the base, the suction portion is located on the side of the cover facing the base.

[0035] This embodiment provides a specific implementation in which the orthographic projection of the suction portion in the vertical direction of the suction surface does not overlap with the orthographic projections of the first opening and the second opening, respectively, and in the extension direction of the suction surface, the orthographic projection of the suction portion does not overlap with the orthographic projection of the second opening. In this specific implementation, the suction portion is located on the side of the cover facing the base, and the suction portion does not interfere with the covering of the cover.

[0036] In some embodiments of this application, the suction portion extends from the bottom end of the side frame toward the outside of the side frame. The suction portion has a non-suction surface facing away from the suction surface, and the non-suction surface is inside the bottom surface.

[0037] In this embodiment, the suction part extends from the bottom end of the side frame to the outside of the side frame, which can make room for the cover in the vertical direction of the suction surface, so that the cover can extend to the outside of the side frame for fastening, thereby making the cover less likely to come loose.

[0038] In some embodiments of this application, the side frame is constructed as an elongated strip with a length greater than its width. The side frame has a long side wall extending in the length direction and a short side wall extending in the width direction. The suction portion extends from the bottom end of the long side wall toward the outside of the long side wall, or extends from the bottom end of the short side wall toward the outside of the short side wall.

[0039] In this embodiment, when the pick-up portion extends from the bottom end of the long sidewall towards the outside of the long sidewall, the pick-up portion can utilize the length advantage of the long sidewall to form a pick-up surface that meets SMT pick-up requirements and whose length is significantly greater than its width. The smaller the width of the pick-up surface, the shorter the distance the pick-up portion extends towards the outside of the long sidewall, and the lower the risk of the pick-up portion rubbing against the device on the outside of the long sidewall. It should be noted that when the pick-up portion extends from the bottom end of the long sidewall towards the outside of the long sidewall, the non-pick-up surface of the pick-up portion and the first opening are distributed side by side in the width direction of the side frame, occupying more space in the width direction of the side frame. Therefore, the shielding cover of this embodiment is suitable for electronic devices where the male and female connectors and surrounding devices have sufficient spacing in the width direction of the side frame.

[0040] When the suction part extends from the bottom end of the long sidewall towards the outside of the long sidewall, the short sidewall, being a short side, has a relatively limited dimension in the width direction of the side frame. Therefore, the fastening hole has no space to move towards the edge of the short sidewall in the width direction of the side frame. Based on this, to meet the required spacing between the fastening hole and the edge of the short sidewall in the vertical direction of the suction surface, the suction part is not suitable to move upwards on the short sidewall. Therefore, in this embodiment, the suction part extends from the bottom end of the short sidewall towards the outside of the short sidewall. It should be noted that the non-suction surface of the suction part and the first opening are distributed side-by-side in the length direction of the side frame, occupying a significant amount of space in that direction. Therefore, the shielding cover of this embodiment is suitable for electronic devices where the components surrounding the male and female connectors have sufficient spacing in the length direction of the side frame.

[0041] In some embodiments of this application, the side frame has a bottom end face facing away from the cover. The base also includes a second plate portion. The second plate portion includes a first plate surface and a second plate surface disposed opposite to each other. The first plate surface of the second plate portion forms a bottom surface, and the second plate surface of the second plate portion fixes the bottom end face of the side frame. The second plate portion extends to the outer side of the side frame. The second plate portion has a third through hole inside the side frame. The third through hole forms a first opening on the first plate surface of the second plate portion and communicates with the first through hole on the second plate surface of the second plate portion.

[0042] This embodiment provides a specific implementation of a base's bottom surface and a first opening on the bottom surface communicating with a first through hole. It should be noted that the bottom surface is used to solder the base to the motherboard of the electronic device. Here, the first surface of the second plate portion forms the bottom surface, and the first surface of the second plate portion is used to solder the base to the motherboard of the electronic device. In this embodiment, the second plate portion extends to the outer side of the side frame to widen the area for soldering the motherboard to the base, thereby improving connection reliability and reducing the risk of poor soldering.

[0043] In some embodiments of this application, the side frame has a second long sidewall extending in the longitudinal direction. A cable tray is formed between the shielding cover and the second long sidewall and the cover. The cable tray is used for the FPC flexible flat cable of the power supply connector to pass through the shielding cover. A second notch is provided on the outer side of the second long sidewall. The second notch faces away from the second long sidewall to avoid the FPC flexible flat cable.

[0044] It should be noted that during the daily use of electronic devices, the FPC flexible flat cable inevitably moves relative to the shielding cover. Because the second plate extends to the outer side of the side frame and is close to the FPC flexible flat cable, the cable is prone to rubbing against the second plate when it moves closer to the shielding cover. In this embodiment, the second plate avoids the FPC flexible flat cable by providing a second long sidewall facing it, thus reducing the risk of rubbing and extending the lifespan of the cable.

[0045] In some embodiments of this application, the cover includes a top and an extension. The top covers the top surface and covers the second opening. When the cover is placed on the base, the extension extends from the top to the outside of the side frame and is detachably engaged with the side frame.

[0046] In this embodiment, the cover extends to the outside of the side frame via an extension portion and is detachably engaged with the side frame. This creates a force from the cover towards the base, making the cover more securely mounted on the base and less prone to falling off, thereby improving the reliability of the shielding cover.

[0047] In some embodiments of this application, the extension includes a first inclined portion and a second inclined portion. A first end of the first inclined portion is connected to the top of the cover, and a second end of the first inclined portion extends inclinedly towards the side frame from the outside. A first end of the second inclined portion connects to the second end of the first inclined portion to form a bent portion, and a second end of the second inclined portion tilts away from the side frame from the outside. The bent portion abuts against the side frame at its bend position.

[0048] In this embodiment, the first inclined portion and the second inclined portion exert a force on the bent portion toward the side frame. This force can press the bent portion against the side frame, making the bent portion more firmly fit with the side frame, thereby making the cover more firmly placed on the base and less likely to fall off, thus improving the reliability of the shielding cover.

[0049] Furthermore, the second inclined portion slopes outward from the side frame, creating a funnel-shaped opening on the cover. This guides the cover during the fastening process, making it easier to align and fasten with the base. Additionally, during the fastening process, the surface of the second inclined portion, rather than a corner, contacts the base, reducing the risk of scratches and damage.

[0050] In some embodiments of this application, a third notch is provided on the second inclined portion, the third notch facing the side to which the second end of the second inclined portion faces. The third notch is used to avoid devices on the side to which the second end of the second inclined portion faces.

[0051] It should be noted that the installation of the shield requires sufficient clearance between it and the surrounding components of the male and female connectors to reduce the risk of scratches. However, because the second end of the second inclined portion gradually tilts away from the side frame, the distance between the second inclined portion and these surrounding components is relatively short. To meet the clearance requirement, in this embodiment, the second end of the second inclined portion is provided with a third notch facing the side towards which the second end of the second inclined portion faces, thereby avoiding the components on the side towards which the second end of the second inclined portion faces, thus ensuring that the shield meets the clearance requirement.

[0052] In some embodiments of this application, the extension further includes a protrusion located at the bend of the bent portion. A fastening hole is provided on the side frame. When the cover is placed on the base, the protrusion is inserted into the fastening hole and subjected to an interference fit.

[0053] In this embodiment, a simple structure with a convex bulge embedded in the fastening hole and an interference fit allows the bent portion to be securely fitted to the side frame, thereby improving the reliability of the shielding cover. Furthermore, in this embodiment, the convex bulge is located at the bent portion, and the forces exerted on the bent portion by the first and second inclined portions can be superimposed on the convex bulge, making it less likely for the convex bulge to detach from the fastening hole.

[0054] In some embodiments of this application, the side frame includes a first short sidewall and a second short sidewall disposed opposite to each other, and a second long sidewall and a first long sidewall disposed opposite to each other. The first long sidewall, the first short sidewall, the second long sidewall, and the second short sidewall are connected end to end in sequence. The second long sidewall is used to construct a cable tray opening. One or more of the first short sidewall, the second short sidewall, and the first long sidewall are provided with fastening holes.

[0055] In this embodiment, because the second long sidewall is used to construct the cable tray, its vertical height in the suction surface is relatively low, which does not meet the spacing requirements for the fastening holes. Therefore, in this embodiment, fastening holes are provided on one or more of the first short sidewall, the second short sidewall, and the first long sidewall.

[0056] In some embodiments of this application, the number of fastening holes is less than or equal to eight. To meet the required spacing between the fastening holes and the corners of the two side walls, a maximum of two fastening holes spaced apart in the width direction can be provided on the first short side wall and the second short side wall. Without the first notch, a maximum of four fastening holes spaced apart in the length direction can be provided on the first long side wall. Therefore, the number of fastening holes in this embodiment is less than or equal to eight. It should be understood that a greater number of fastening holes results in a stronger fastening force, effectively reducing the risk of the male and female connectors becoming loose.

[0057] Secondly, embodiments of this application also provide an electronic device. This electronic device includes a motherboard, a male and female connector, and a shielding cover as described in any embodiment of the first aspect. The bottom surface of the base of the shielding cover is fixed to the motherboard. The male and female connector includes a male socket and a female socket. The female socket of the male and female connector is electrically connected to the motherboard and extends into the shielding chamber of the shielding cover through a first opening. The male socket of the male and female connector extends into the shielding chamber through a second opening to engage the female socket. In the vertical direction of the first direction, the suction portion is spaced apart from the male socket. In the vertical direction of the second direction, the suction portion is spaced apart from the female socket.

[0058] It should be noted that when the first direction is the vertical direction and the extension direction of the suction surface, then the vertical direction of the first direction also has two directions, namely the vertical direction of the suction surface and the vertical direction of the extension direction of the suction surface. When the second direction is the vertical direction and the extension direction of the suction surface, then the vertical direction of the second direction also has two directions, namely the vertical direction of the suction surface and the vertical direction of the extension direction of the suction surface.

[0059] In some embodiments of this application, the female connector includes a female connector body and a first mating portion. A main board is fixed to the bottom surface of the female connector body, and the first mating portion is disposed on the top surface of the female connector body. The male connector includes a male connector body and a second mating portion. The male connector body is disposed on the side of the female connector facing away from the main board, and the second mating portion is disposed on the surface of the male connector body facing the female connector. The second mating portion and the first mating portion are inserted to form a mating portion. The male connector body has an overflow portion that extends to the side of the mating portion in the extending direction. Suction portions are spaced apart on the side of the mating portion, and are spaced apart between the overflow portion and the reference plane containing the top surface of the female connector body.

[0060] In this embodiment, the shield needs to leave sufficient clearance to avoid surrounding components of the male and female connectors to prevent scratches and other problems. This results in less space available for the shield on the motherboard. In this embodiment, the suction section extends using the space below the overflow portion of the male connector, which can improve the space utilization of the shield on the motherboard.

[0061] In some embodiments of this application, the surface of the male connector facing away from the female connector is interference-fitted with the cover of the shield. In this embodiment, the cover, through the interference fit with the surface of the male connector facing away from the female connector, exerts a force on the male connector toward the female connector. This force can more firmly fasten the male connector onto the female connector, thereby improving the electrical connection reliability of the male and female connectors.

[0062] It is understood that the beneficial effects of the electronic device provided by the embodiments of the second aspect described above can be found in the relevant description of the shielding cover in the first aspect described above, and will not be repeated here.

[0092] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0093] This application provides an electronic device. Exemplarily, the electronic device may be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device, etc., including a BTB connector. This application does not impose any special limitations on the specific form of the electronic device. The following description uses a mobile phone as an example.

[0094] For example, please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of an electronic device 00 provided in an embodiment of this application, and Figure 2 is an exploded structural schematic diagram of the electronic device 00 shown in Figure 1.

[0095] In this embodiment, the electronic device 00 is a mobile phone, including a screen 01, a back cover 02, a mid-frame 03, a camera module 04 shown in FIG. 2, a battery 05, and a motherboard 06. It is understood that FIG. 1 only schematically shows some components included in the electronic device 00, and the actual shape, size, position, and structure of these components are not limited to FIG. 1. Furthermore, in other embodiments of this application, the electronic device 00 may include more or fewer components than shown, or combine some components, or split some components, or have different component arrangements.

[0096] Screen 01 is used to display images, videos, etc. Screen 01 includes a cover plate 011 and a display panel 012. The cover plate 011 and the display panel 012 are stacked together. The cover plate 011 mainly protects the display panel 012 and prevents dust. The material of the cover plate 011 can be, but is not limited to, glass. The display panel 012 can be a flexible display or a rigid display. For example, the display panel 012 can be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, a quantum dot light-emitting diode (QLED) display, or a liquid crystal display (LCD).

[0097] For ease of description below, an XYZ coordinate system is established, defining the width direction of electronic device 00 as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. It can be understood that the stacking direction of the inner screen cover 011 and the display screen 012 of electronic device 00 is the Z-axis. It should be noted that the coordinate system settings of electronic device 00 can be flexibly configured according to actual needs.

[0098] The back cover 02, also known as the battery cover, is used to protect the internal electronic components of the electronic device 00. The back cover 02 is located on the side of the display screen 012 away from the screen cover plate 011, and is stacked with the screen cover plate 011 and the display screen 012.

[0099] The mid-frame 03 is located between the screen 01 and the back cover 02, and is used to mount the internal functional components of the electronic device 00. For ease of explanation, in this embodiment, the structure formed by the mid-frame 03 and the internal functional components (such as the camera module 04, battery 05, and motherboard) mounted on the mid-frame 03 is referred to as functional part 03a. The mid-frame 03 includes a frame 031 and a middle plate 032.

[0100] The frame 031 surrounds the sides of the screen 01 and the back cover 02, and is fixedly connected to the screen 01 and the back cover 02 respectively. Exemplarily, the frame 031 can be fixedly connected to the screen 01 and the back cover 02 respectively using adhesive. In some other embodiments, the frame 031 and the back cover 02 can also be integrally formed, that is, the frame 031 and the back cover 02 are a single structure. It can be understood that the screen 01, the back cover 02, and the frame 031 together enclose a receiving space for the electronic device 00, so that the functional components of the electronic device 00 can be placed through this receiving space, such as the camera module 04, motherboard, battery 05, etc., as shown in FIG2, while simultaneously providing a sealing and protection function for the functional components located within the receiving space.

[0101] As shown in Figure 2, the middle plate 032 is fixed around the inner surface of the frame 031. Exemplarily, the middle plate 032 can be fixed to the frame 031 by welding. Alternatively, the middle plate 032 and the frame 031 can be integrally formed. The structure formed by the middle plate 032 and the frame 031 is commonly referred to as the middle frame 03. The middle plate 032 serves as the structural "skeleton" of the electronic device 00, housing functional components such as the camera module 04, battery 05, motherboard, etc.

[0102] For example, the motherboard is fixed to the surface of the middle plate 032 near the back cover 02. The motherboard has mounting holes through which the camera module 04 passes and is fixed to the middle plate 032. The battery 05 is fixed side-by-side to one side of the motherboard.

[0103] The camera module 04 is used to capture photos / videos. There can be one or more camera modules 04; only one camera module 04 is shown in the figure, used as the main camera 04. The camera module 04 is fixed in the housing space of the electronic device 00. Exemplarily, the camera module 04 can be fixed and supported on the middle plate 032 by means of threaded connection, snap-fit, welding, etc. In some embodiments, the camera module 04 can be used as a rear camera module 04; the illustrated camera module 04 is also referred to as the main camera 04. The light-incident surface of the camera module 04 faces the back cover 02, which has a camera decorative cover 021 for protecting and decorating the camera module 04. In some other embodiments, the camera module 04 can also be used as a front camera module 04. In this case, the camera module 04 can be fixed to the surface of the middle plate 032 near the screen cover 011. The light-incident surface of the camera module 04 faces the screen cover 011.

[0104] Battery 05 is used to power the functional components of electronic device 00 that require power.

[0105] The motherboard 06 (also known as a printed circuit board) is an important carrier for functional components. It typically has metal traces and / or interfaces to facilitate electrical connections between functional components, whether integrated or not. Specifically, functional components are electrically connected to the motherboard 06 through soldering or other methods, and can be electrically connected to other functional components through the metal traces and / or interfaces on the motherboard 06.

[0106] This application uses a microcontroller unit (MCU) (not shown in the figure) as the functional component and other functional components as the main camera 04 as an example for illustration.

[0107] For example, please refer to Figure 3, which is a schematic diagram of the cross-sectional structure obtained by cutting the functional part 03a shown in Figure 2 along the cutting line B1-B1.

[0108] In order to realize the electrical connection between the microcontroller and the main camera 04 through the motherboard 06, the electronic device 00 also includes a male and female connector 07.

[0109] The male and female connector 07 is a connector that includes a female socket 071 and a male socket 072. For example, the male and female connector 07 can be a BTB connector 07, and subsequent embodiments will be described using the BTB connector 07 as an example.

[0110] The female connector 071 of the male-female connector 07 is electrically connected to the motherboard 06, serving as an interface for the motherboard 06. The male connector 072 of the male-female connector 07 is typically electrically connected to one end of the flexible printed circuit (FPC) 041 (referred to as FPC flexible cable 041 in this embodiment), while the other end of the FPC flexible cable 041 is electrically connected to the main camera 04. In some embodiments, the FPC flexible cable 041 can be considered as part of the main camera 04. It is understood that in other embodiments, the FPC flexible cable 041 is not limited to being electrically connected to the main camera 04; subsequent embodiments will use the FPC flexible cable 041 and the main camera 04 as examples for illustration.

[0111] The male connector 072 can be engaged with the female connector 071, thus putting the male-female connector 07 in an engaged state. Alternatively, the male connector 072 can be removed from the female connector 071, thus separating the male-female connector 07. It can be understood that when the male connector 072 of the BTB connector 07 is engaged with the female connector 071, the main camera 04 can be electrically connected to the MCU via the motherboard 06, thereby enabling signal transmission between the main camera 04 and the MCU.

[0112] The electromagnetic waves generated by the BTB connector 07 during operation can cause electromagnetic interference to surrounding devices (such as device 09), thereby reducing the performance of these devices. For example, because the BTB connector 07 is close to the mid-frame antenna 31 (in the case where the frame 031 is used as an antenna) and the main camera 04, the electromagnetic waves generated by the BTB connector 07 may interfere with antenna performance and shooting performance.

[0113] Therefore, it is necessary to install a shielding cover 08 on the motherboard 06 to cover the BTB connector 07 in order to isolate the electromagnetic interference of the BTB connector 07 to surrounding devices.

[0114] For example, please refer to Figures 4 and 5. Figure 4 is a structural schematic diagram of a shield 08 provided in the embodiment of this application in an assembled state, and Figure 5 is a structural decomposition schematic diagram of the shield 08 shown in Figure 4 obtained by decomposing it in the Z-axis direction.

[0115] The shielding cover 08 includes a base 100 and a cover 200. The cover 200 is detachably mounted on the base 100. The aforementioned "assembled state" of the shielding cover 08 refers to the state where the cover 200 is mounted on the base 100. Correspondingly, the shielding cover 08 can also have a non-assembled state, that is, a state where the cover 200 is not mounted on the base 100 and is separated from the cover. It should be noted that the shielding cover 08 can be in the assembled state shown in Figure 4 or in a non-assembled state at the time of manufacture; this embodiment does not specifically limit this. The following description uses the shielding cover 08 in the assembled state as an example.

[0116] The base 100 and the cover 200 will be described in detail below.

[0117] First, the base 100 will be described by example.

[0118] Referring to Figure 5, the base 100 has a bottom surface S1 and a top surface S2 arranged opposite to each other in the Z-axis direction. The bottom surface S1 of the base 100 is fixed to the upper surface of the motherboard 06 in Figure 2. In practice, the bottom surface S1 of the base 100 can be soldered to the upper surface of the motherboard 06 using surface mount technology (SMT). In this case, the bottom surface S1 of the base 100 can also be referred to as the solder surface. To improve the reliability of the electrical connection, the bottom surface S1 of the base 100 is relatively flat; for example, the flatness of the bottom surface S1 of the base 100 is 0.1.

[0119] The bottom surface S1 has a first opening 100a, and the top surface S2 has a second opening 100b. The first opening 100a and the second opening 100b are connected.

[0120] For example, referring to FIG5, the base 100 includes a first plate portion 110, a second plate portion 120, and a side frame 130. In some other embodiments, the base 100 may also include more or fewer components. For example, the base 100 may not include the first plate portion 110; or, if the thickness of the side frame 130 is sufficient to meet the welding requirements, the base 100 may not include the second plate portion 120.

[0121] The side frame 130 is constructed as an elongated strip with a length greater than its width to accommodate the elongated BTB connector 07. Of course, in other embodiments, the BTB connector 07 can also have other shapes, and the side frame 130 can also be constructed in other shapes. When the side frame 130 is constructed as an elongated strip, it includes two opposing short sidewalls 132 and two opposing long sidewalls 131.

[0122] In this embodiment, the short sidewall 132 extends in the width direction (X-axis direction in the diagram), and the long sidewall 131 extends in the length direction (Y-axis direction in the diagram). For ease of distinction and explanation, the two short sidewalls 132 are referred to as the first short sidewall 1321 and the second short sidewall 1322, and the two long sidewalls 131 are referred to as the first long sidewall 1311 and the second long sidewall 1312. The first long sidewall 1311, the first short sidewall 1321, the second long sidewall 1312, and the second short sidewall 1322 are connected end to end in sequence to form a side frame 130 with a first through hole 100c extending along the Z-axis direction. Optionally, the position where each sidewall is connected, i.e., the corner position of each sidewall, is constructed as an R-angle.

[0123] In this embodiment, the wall of the first through hole 100c of the side frame 130 is referred to as the inner wall surface of the side frame 130, and the surface of the side frame 130 facing away from the inner wall surface is referred to as the outer wall surface of the side frame 130. The side facing the inner wall surface of the side frame 130 is called the inner side of the side frame 130, and the side facing the outer wall surface of the side frame 130 is called the outer side of the side frame 130.

[0124] The first plate portion 110 extends from the top of the side frame 130 toward the inner side of the side frame 130; therefore, the first plate portion 110 does not have a region extending to the outer side of the side frame 130. The first plate portion 110 includes a first plate surface and a second plate surface disposed opposite to each other in the Z-axis direction. For ease of understanding, in the embodiments of this application, the first plate surface of the first plate portion 110 is referred to as the lower plate surface of the first plate portion 110; and the second plate surface of the first plate portion 110 is referred to as the upper plate surface of the first plate portion 110.

[0125] The upper surface of the first plate portion 110 forms the top surface S2 of the base 100, and the lower surface of the first plate portion 110 fixes the top surface of the side frame 130. The first plate portion 110 has a second through hole that penetrates both the upper and lower surfaces of the first plate portion 110, forming a second opening 100b on the upper surface of the first plate portion 110, and communicating with the first through hole 100c on the lower surface of the first plate portion 110, thereby enabling the first opening 100a to communicate with the first through hole 100c.

[0126] Optionally, the outer wall surface of the side frame 130 and the upper plate surface of the first plate portion 110 have an arc-shaped surface. That is, the original right-angle corner between the outer wall surface of the side frame 130 and the upper plate surface of the first plate portion 110 is adjusted to an R-angle. In this way, when the cover 200 is moved along the negative Z-axis towards the base 100 to place the cover 200 on the base 100, the risk of the cover 200 being damaged by the original right-angle corner can be reduced.

[0127] The second plate portion 120 is the part of the base 100 that fixes the main board 06 shown in FIG2. In this embodiment, the second plate portion 120 extends along the bottom end surface of the side frame 130 in the O-XY plane and extends to the outside of the side frame 130. That is, the second plate portion 120 extends beyond the side frame 130 in the O-XY plane, and the orthographic projection of the side frame 130 in the Z-axis direction falls within the edge of the second plate portion 120. In this embodiment, the part of the second plate portion 120 that extends beyond the side frame 130 in the O-XY plane is referred to as the part of the second plate portion 120 outside the side frame 130. This part is also commonly referred to as the skirt, which is used to widen the area of ​​the base 100 for welding the main board 06 shown in FIG2.

[0128] The second plate portion 120 includes a first plate surface and a second plate surface disposed opposite to each other in the Z-axis direction. For ease of understanding, in the embodiments of this application, the first plate surface of the second plate portion 120 is referred to as the lower plate surface of the second plate portion 120; and the second plate surface of the second plate portion 120 is referred to as the upper plate surface of the second plate portion 120.

[0129] The lower surface of the second plate portion 120 forms the bottom surface S1 of the base 100, which is the area where the second plate portion 120 is specifically used to fix the main board 06 shown in FIG. 2. The upper surface of the second plate portion 120 fixes the bottom end surface of the side frame 130. The second plate portion 120 has a third through hole inside the side frame 130, that is, the orthographic projection of the third through hole in the Z-axis direction falls within the orthographic projection of the first through hole 100c in the Z-axis direction of the side frame 130. The third through hole penetrates the upper and lower surfaces of the second plate portion 120, forming a first opening 100a on the lower surface of the second plate portion 120, and communicating with the first through hole 100c on the upper surface of the second plate portion 120, thereby making the second opening 100b communicate with the first through hole 100c. It can be understood that when the second plate portion 120 is provided with a third through hole aligned with the second through hole, the second plate portion 120 is the part of the base 100 distributed on the outer side of the bottom end of the side frame 130.

[0130] It should be noted that the top surface of the side frame 130 is the end surface of the side frame 130 facing the cover 200; the bottom surface of the side frame 130 is the end surface of the side frame 130 facing away from the cover 200. The top and bottom surfaces of the side frame 130 are set opposite to each other in the Z-axis direction.

[0131] In this embodiment, since the top surface of the side frame 130 fixes the lower surface of the first plate portion 110, and the bottom surface of the side frame 130 fixes the upper surface of the second plate portion 120, the side frame 130 is naturally located between the upper surface of the first plate portion 110 and the lower surface of the second plate portion 120, that is, between the top surface S2 and the bottom surface S1 of the base 100. The second through hole of the first plate portion 110 connects the second opening 100b with the first through hole 100c, and the third through hole of the second plate portion 120 connects the first opening 100a with the first through hole 100c. Thus, the first opening 100a communicates with the second opening 100b through the first through hole 100c.

[0132] It is understood that when the base 100 does not include the first plate portion 110, the top surface of the side frame 130 forms the top surface S2 of the base 100; when the base 100 does not include the second plate portion 120, the bottom surface of the side frame 130 forms the bottom surface S1 of the base 100. In this case, the side frame 130 is naturally located between the top surface S2 and the bottom surface S2 of the base 100.

[0133] Please refer to Figure 5. The base 100 also includes a suction unit 140.

[0134] The suction unit 140 has a suction surface 141, which faces away from the bottom surface S1 of the base 100. During the process of mounting the base 100 onto the motherboard 06 in FIG2 using SMT, the suction surface 141 is used for the suction of the SMT-used pick-up tip (referred to as SMT pick-up tip).

[0135] To meet the requirements of SMT pick-up, in the specific implementation process, the pick-up surface 141 can be a surface with an area greater than or equal to 4mm2 and a width greater than or equal to 1mm. The width refers to the short side dimension of the pick-up surface 141.

[0136] In some embodiments, in order to ensure that the base 100 can be fixed to the motherboard 06 without tilting, the suction surface 141 is parallel to the reference plane where the bottom surface S1 is located. Thus, during the process of using an SMT pick-up tool to pick up the suction surface 141 and install the base 100 onto the motherboard 06 shown in FIG. 2, because the suction surface 141 is parallel to the motherboard 06 shown in FIG. 2, and the suction surface 141 is parallel to the reference plane where the bottom surface S1 of the base 100 is located, the bottom surface S1 of the base 100 can be fixed parallel to the motherboard 06 without tilting.

[0137] In the embodiment shown in Figure 5, the suction part 140 fixes the side frame 130 and extends from the side frame 130 toward the inside of the side frame 130, and is spaced between the first plate part 110 and the second plate part 120.

[0138] For example, referring to Figure 5, the suction part 140 fixes the long side wall 131 of the side frame 130 and extends from the long side wall 131 toward its inner side. It should be noted that the inner side of the long side wall 131 is the side facing which the inner wall surface of the long side wall 131 faces, and the area corresponding to the inner wall surface of the long side wall 131, i.e., the inner wall surface of the side frame 130, is the area of ​​the long side wall 131. Furthermore, this embodiment also relates to the outer side of the long side wall 131. The outer side of the long side wall 131 is the side facing which the outer wall surface of the long side wall 131 faces, and the area corresponding to the outer wall surface of the long side wall 131, i.e., the outer wall surface of the side frame 130, is the area of ​​the long side wall 131. Additionally, this embodiment also relates to the outer and inner sides of the short side wall, which can be understood with reference to the explanations herein and will not be repeated hereafter.

[0139] It should be noted that, since the long sidewall 131 extends in the length direction, the suction portion 140 can utilize the length advantage of the long sidewall 131 to form a suction surface 141 that meets the SMT suction requirements and whose length is significantly greater than its width. The smaller the width of the suction surface 141, the shorter the distance that the suction portion 140 extends inward toward the long sidewall 131, the larger the distance between the suction portion 140 and the BTB connector 07, and the lower the risk of the suction portion 140 rubbing against the aforementioned BTB connector 07. Of course, in some other embodiments, the suction portion 140 may also extend inward from other sidewalls of the side frame 130, and this application embodiment does not limit this.

[0140] Specifically, referring to Figure 5, the suction portion 140 extends from the first long side wall 1311 toward the inner side of the first long side wall 1311. The first long side wall 1311 is a long side wall 131 disposed opposite to the second long side wall 1312.

[0141] In this embodiment, the long side wall 131 closest to the camera module 04 shown in FIG3 is referred to as the second long side wall 1312. It is understood that, in order to allow the FPC flexible flat cable 041 in FIG3 to pass through the shielding cover 08, the long side wall 131 closest to the camera module 04 shown in FIG3 needs to be used to construct a cable port. The cable port is used for the FPC flexible flat cable 041 connecting the power connector 072 to pass through the shielding cover 08. Based on this, the second long side wall 1312 is the long side wall 131 among the two long side walls 131 used to construct the cable port.

[0142] The following description, in conjunction with Figure 6, provides an exemplary illustration of the specific implementation of the wiring port construction on the second long side wall 1312.

[0143] For example, please refer to Figure 6, which is a schematic diagram of the fastening process of the shield 08 shown in Figure 5 from another perspective.

[0144] The second long side wall 1312 and the second long side plate 1112 of the first plate 110 corresponding to the second long side wall 1312 sink down along the negative Z-axis to below the lower plate surface of the first plate 110. The first short side wall 1321 and a portion of the first short side plate of the first plate 110 corresponding to the first short side wall 1321 respectively tilt and transition to the sinking second long side wall 1312 and the second long side plate 1112. The second short side wall 1322 and a portion of the second short side plate of the first plate 110 corresponding to the second short side wall 1322 respectively tilt and transition to the sinking second long side wall 1312 and the second long side plate 1112, thereby forming a lower notch 100e on the base 100.

[0145] An upper notch 200a is formed on the cover 200. The upper notch 200a extends from one end of the top 210 of the cover near the second long side wall 1312 to an extension 220 on the outer side of the second long side wall 1312, and penetrates the extension 220 in the Z-axis direction to prevent the cover 200 from pressing on the FPC flexible flat cable 041. When the cover 200 is placed on the base 100, the cover 200 and the base 100 are enclosed by the upper notch 200a and the lower notch 100e to form the cable port 080a of the shield 08. The cable port 080a is used for the FPC flexible flat cable 041, which is electrically connected to the male connector 072, to pass through to the outside of the shield 08. It should be noted that in other embodiments, the specific formation of the cable port 080a may also be in other ways, and this application embodiment does not limit this.

[0146] Referring to Figure 5, the suction part 140 extends from the first long side wall 1311 opposite to the second long side wall 1312 toward the inside of the first long side wall 1311. In this case, the FPC flexible flat cable 041 passing through the cable port 080a of the second long side wall 1312 to the outside of the shield 08 and the suction part 140 are located on opposite sides of the male connector 072, respectively. The FPC flexible flat cable 041 is less prone to friction between the suction parts 140, thereby improving the electrical connection reliability of the FPC flexible flat cable 041.

[0147] It is understood that the suction portion 140 is spaced below the first plate portion 110, that is, on the side facing the lower surface of the first plate portion 110. In order not to interfere with the SMT suction head's suction of the suction surface 141, the orthographic projection of the first plate portion 110 and the orthographic projection of the suction portion 140 do not overlap in the vertical direction of the suction surface 141 (referred to as the vertical direction, i.e., the Z-axis direction shown in the figure), so that the orthographic projection of the suction surface 141 along the Z-axis direction onto the side facing the suction surface 141 falls on the cover 200. The orthographic projection of the suction surface 141 along the Z-axis direction onto the side facing the suction surface 141 is the orthographic projection of the suction surface 141 along the positive Z-axis direction.

[0148] It should be noted that when the base 100 does not have a shielding structure on the projection path of the suction surface 141 along the positive Z-axis, the positive projection of the suction surface 141 along the positive Z-axis falls on the cover 200. Thus, when the SMT nozzle moves towards the suction surface 141 along the negative Z-axis, the base 100 does not have a shielding structure that can block the movement of the SMT nozzle, thereby not interfering with the SMT nozzle's suction of the suction surface 141.

[0149] In order to ensure that the orthographic projection of the first plate portion 110 in the Z-axis direction does not overlap with the orthographic projection of the suction portion 140 in the Z-axis direction, optionally, referring to FIG5, the suction portion 140 extends from the first long side wall 1311 along the bottom surface of the first notch 100d of the base 100 toward the inside of the first long side wall 1311. In this case, the bottom surface of the first notch 100d is the suction surface 141 of the suction portion 140.

[0150] The first notch 100d extends along the Z-axis, penetrates the first long side plate portion 1111, and sinks below the top surface of the first long side wall 1311 (i.e., the side of the top surface facing the negative Z-axis). The first long side plate portion 1111 is the part of the first plate portion 110 corresponding to the first long side wall 1311. The part of the first plate portion 110 corresponding to the first long side wall 1311 refers to the part of the first plate portion 110 extending from the top surface of the first long side wall 1311 towards the inner side of the first long side wall 1311. The definitions of the second long side plate portion, the first short side plate portion, and the second short side plate portion involved in the embodiments of this application can be adapted to refer to the description of the first long side plate portion.

[0151] It should be noted that when the suction part 140 extends along the bottom surface of the first notch 100d to the inside of the first long side wall 1311, since the first notch 100d extends through the first long side plate 1111 in the Z-axis direction, the suction part 140 is directly opposite the opening formed by the first notch 100d penetrating the first long side plate 1111 in the Z-axis direction. The first plate 110 no longer has a shielding structure that can block the movement of the SMT suction head, so that the suction of the SMT suction head on the suction surface 141 can be carried without interference.

[0152] It should be noted that the components of the base 100 shown in Figure 5 can be integrally formed. Of course, in some other embodiments, the components of the base 100 can also be connected by welding or other methods, and this application does not limit this.

[0153] Next, the cover 200 will be described by way of example.

[0154] The cover 200 is used to detachably cover the base 100 and cover the second opening 100b.

[0155] For example, referring to FIG5, the cover 200 includes a top cover 210 and an extension 220. The top cover 210 is the portion of the cover 200 distributed on the side facing the top surface S2, and the top cover 210 covers the top surface S2 and covers the second opening 100b. The extension 220 fixes the top cover 210 and extends from the top cover 210 to the outside of the side frame 130, and is detachably engaged with the side frame 130 to detachably cover the cover 200 onto the base 100.

[0156] In practice, the extension 220 can be fixed to the top of the cover 210 by welding or other means, or it can be integrally formed with the top of the cover 210.

[0157] To facilitate the fastening of the cover 200, the extension 220 may optionally be cut at the radius (R) corners of the adjacent sidewalls; that is, the extension 220 may not have portions distributed at the radius (R) corners of the adjacent sidewalls. This allows the extension 220 to be more easily pushed outwards by the side frame 130, thereby making it easier for the cover 200 to move in the Z-axis direction for fastening.

[0158] Optionally, referring to Figure 5, the extension 220 includes a first inclined portion 221 and a second inclined portion 222. The first end of the first inclined portion 221 is fixedly connected to the top of the cover 210, and the second end of the first inclined portion 221 is inclined towards the side frame 130 from the outside. The first end of the second inclined portion 222 is connected to the second end of the first inclined portion 221 to form a bend 220a, and the second end of the second inclined portion 222 is inclined away from the side frame 130 from the outside.

[0159] On one hand, the second inclined portion 222 is inclined away from the side frame 130 on the outer side of the side frame 130, which can form a funnel-shaped opening on the cover 200. In this way, during the fastening process of the cover 200, it can guide the cover 200, making it easier to align the cover 200 with the base 100 for fastening. Furthermore, during the fastening process of the cover 200 moving in the negative Z-axis direction, the plate surface of the second inclined portion 222, rather than the corner, contacts the base 100, which can reduce the risk of scratch damage.

[0160] On the other hand, the extension 220 also allows the cover 200 to be more securely attached to the base 100 and less likely to fall off.

[0161] Specifically, please refer to Figures 5 and 7. Figure 7 is a schematic cross-sectional view of the shield 08 shown in Figure 4, obtained by cutting along the section line B2-B2.

[0162] The bent portion 220a abuts against the side frame 130. In this embodiment, the first inclined portion 221 and the second inclined portion 222 exert a force F1 on the bent portion 220a toward the side frame 130. This force F1 can press the bent portion 220a against the side frame 130, making the bent portion 220a more firmly engaged with the side frame 130. This makes the cover 200 more firmly placed on the base 100 and less likely to fall off, thereby improving the reliability of the shielding cover 08.

[0163] In some embodiments of this application, please continue to refer to FIG5. In order to make the cover 200 more securely cover the base 100, the extension 220 further includes a protrusion 223 provided on the bending portion 220a, and the side frame 130 is provided with a fastening hole 130a adapted to the protrusion 223. The fastening hole 130a adapted to the protrusion 223 refers to a hole whose size allows the protrusion 223 to be inserted and can form an interference fit with the protrusion 223.

[0164] Please refer to Figures 5 and 8. Figure 8 is a schematic cross-sectional view of the shield 08 shown in Figure 4, obtained by cutting along the section line B3-B3.

[0165] In the assembled state, the convex bulge 223 is inserted into the fastening hole 130a and subjected to an interference fit. In this embodiment, the simple structure of the convex bulge 223 being inserted into the fastening hole 130a and subjected to an interference fit allows the bent portion 220a to be firmly engaged with the side frame 130, thereby improving the reliability of the shielding cover 08.

[0166] Furthermore, in this embodiment, the protrusion 223 is disposed at the bend 220a. The force F1 exerted by the first inclined portion 221 and the second inclined portion 222 on the bend 220a can be superimposed on the protrusion 223, thereby making it difficult for the protrusion 223 to fall out of the fastening hole 130a. In this case, the bend 220a abuts against the side frame 130 at other locations besides the protrusion 223.

[0167] Of course, in other embodiments, the bent portion 220a and the side frame 130 can also be detachably fitted in other ways. For example, the bent portion 220a directly abuts against the side frame 130 via a protrusion 223. Another example is that the bent portion 220a directly abuts against the side frame 130; in this case, to reduce damage caused by the bent portion 220a scraping against the side frame 130, the bent portion 220a has an arc-shaped structure.

[0168] It should be noted that the one-piece molded base 100 is typically formed by stamping a flat substrate. During the stamping process, the closer the substrate is to the edge of the side frame 130 in the Z-axis direction, the greater the tensile force and the more obvious the deformation. The fastening holes 130a are also usually first formed on the substrate, and deform accordingly as the substrate is stamped.

[0169] Therefore, if the fastening hole 130a is too close to the edge of the side frame 130 in the Z-axis direction, the fastening hole 130a will be overstretched due to a large tensile force, forming an elongated hole. The elongated hole has two drawbacks: First, it cannot be fitted with the protrusion 223, and the protrusion 223 cannot be inserted into the fastening hole 130a for fastening; second, although the protrusion 223 can be inserted, it has a certain amount of movement in the Z-axis direction after insertion, making the cover 200 prone to loosening. Based on these two points, the fastening hole 130a and the edge of the side frame 130 in the Z-axis direction should maintain a sufficient distance.

[0170] In Figure 5, because the second long side wall 1312 is used to construct the cable tray, its height in the Z-axis direction is relatively low, which does not meet the spacing requirements of the fastening hole 130a. Therefore, in Figure 5, the first short side wall 1321, the second short side wall 1322, and the first long side wall 1311 are provided with fastening holes 130a.

[0171] Because the first notch 100d is recessed at the bottom of the first long side wall 1311, the spacing required for the fastening hole 130a is not met at the bottom of the first long side wall 1311. To provide the fastening hole 130a on the first long side wall 1311, the first notch 100d penetrates a portion of the first long side plate 1111 and is recessed into the first long side wall 1311, so that the first long side wall 1311 has fastening hole portions 131a distributed along the sides of the first notch 100d in the length direction. In this case, the fastening hole 130a can be provided on the fastening hole portion 131a.

[0172] As can be seen, in this embodiment, since the first long sidewall 1311 is a long side, its dimension in the Y-axis direction is relatively wide. Therefore, the first long sidewall 1311 has space in the Y-axis direction to support the fastening hole portion 131a provided on the side of the first notch 100d. In other words, when the suction portion 140 extends from the first long sidewall 1311 toward the inner side of the first long sidewall 1311, it is suitable to sink to the bottom of the first notch 100d.

[0173] It should be noted that, for a similar reason as the aforementioned snap-fit ​​hole 130a being overstretched, the substrate experiences greater tensile force as it approaches the corner between the two side walls during the stamping process. Therefore, the snap-fit ​​hole 130a and the corner between the two side walls should maintain a sufficient distance.

[0174] Based on this, in Figure 5, to meet the required spacing between the locking hole 130a and the corners of the two side walls, two locking holes 130a are provided on the first short side wall 1321 and the second short side wall 1322, spaced apart in the X-axis direction. On the first long side wall 1311, one locking hole 130a is provided on each of the locking hole portions 131a on opposite sides of the first notch 100d. In this configuration, a total of six locking holes 130a are provided in Figure 5, resulting in a stronger locking force and effectively reducing the risk of the BTB connector 07 becoming loose.

[0175] Optionally, referring to Figure 5, the first notch 100d gradually narrows in the downward direction (negative Z-axis direction in the figure), forming an inverted trapezoid, and the opening of the first notch 100d is wider than its bottom. In this case, the fastening hole portions 131a distributed on the sides of the first notch 100d become wider in the negative Z-axis direction, leaving more space for the fastening hole 130a. In this case, the fastening hole 130a can move away from the corner between the two side walls, thereby increasing the distance between the fastening hole 130a and the corner between the two side walls.

[0176] Since the first inclined portion 221 and the second inclined portion 222 provided in the aforementioned extension 220 can reduce the risk of the BTB connector 07 falling off, based on this, in some other embodiments, the number of fastening holes 130a on the first short side wall 1321, the second short side wall 1322, and the first long side wall 1311 can be less, for example, one or none. This application embodiment does not limit this. In this case, one or more of the first short side wall 1321, the second short side wall 1322, and the first long side wall 1311 are provided with fastening holes 130a, and the number of fastening holes 130a on the side frame 130 is less than or equal to 6.

[0177] The components of the cover 200 shown in Figure 5 can be integrally formed. Of course, in some other embodiments, the components of the cover 200 can also be fixed by welding or other methods, and this application does not limit this.

[0178] Please refer to Figure 8. In the assembled state, the cover 200 covers the base 100, forming a shielding chamber 080b. The shielding chamber 080b is used to accommodate the female connector 071 extending through the first opening 100a, and the male connector 072 extending through the second opening 100b and engaging with the female connector 071 to form the male-female connector 07, so as to cover the BTB connector 07 and thus achieve electromagnetic shielding.

[0179] The following describes the installation process of the shield 08 being installed onto the motherboard 06 shown in Figure 2 to cover the BTB connector 07, with reference to Figure 9.

[0180] For example, please refer to Figure 9, which is a schematic diagram of the installation process of the shield 08 shown in Figure 5.

[0181] First, as shown in Figure 9(a), the female connector 071 is electrically connected to the motherboard 06. Using the suction head involved in STM, the suction surface 141 on the base 100 is picked up, and the base 100 is aligned with the female connector 071 (i.e., the first opening 100a of the bottom surface S1 in Figure 5 is aligned). Then, the base 100 is moved along the negative Z-axis until the bottom surface S1 of the base 100 is soldered to the motherboard 06 in Figure 2, thus realizing the installation of the base 100, presenting the state shown in Figure 9(a).

[0182] Next, as shown in Figure 9(b), after aligning the male connector 072 connected to one end of the FPC flexible flat cable 041 with the second opening 100b on the top surface S2, move it along the negative Z-axis until the male connector 072 and the female connector 071 are engaged, presenting the state shown in Figure 9(b).

[0183] Finally, as shown in Figure 9(c), the cover 200 is moved along the negative Z-axis until the protrusion 223 on the cover 200 slides along the outer wall of the side frame 130 into the fastening hole 130a shown in Figure 9(b), thus fastening the cover 200 and achieving the state shown in Figure 9(c). This completes the installation of the shielding cover 08.

[0184] Please refer to Figures 9 and 10. Figure 10 is a schematic cross-sectional view of the structure shown in (c) of Figure 9, obtained by cutting along the cutting line B4-B4.

[0185] With the shielding cover 08 installed, the cover 200 is placed on the base 100 and covers the second opening 100b. The cover 200 and the base 100 together form a shielding chamber 080b and a ribbon cable port 080a communicating with the shielding chamber 080b. The female connector 071 of the BTB connector 07 extends into the shielding chamber 080b through the first opening 100a on the bottom surface S1, and the male connector 072 of the BTB connector 07 extends into the shielding chamber 080b through the second opening 100b on the top surface S2. The FPC flexible ribbon cable 041 exits the shielding cover 08 through the ribbon cable port 080a.

[0186] In the embodiment shown in Figure 10, the suction part 140 is located between the first plate part 110 and the second plate part 120, and is naturally also spaced between the second reference plane P2 where the top surface S2 of the base 100 is located and the first reference plane P1 where the bottom surface S1 is located. That is, there is a gap between the suction surface 141 of the suction part 140 and the second reference plane P2, and there is a gap between the non-suction surface 142 (the non-suction surface that is disposed opposite to the suction surface 141) of the suction part 140 and the bottom surface S1.

[0187] When the suction part 140 is located inside the side frame 130 and the suction surface 141 has a distance between it and the second reference plane P2 where the top surface S2 is located and the first reference plane P1 where the bottom surface S1 is located, the orthographic projection of the suction surface 141 in the extension direction of the suction surface 141 (i.e., any direction in the O-XY plane, such as the X-axis direction or the Y-axis direction; in this embodiment, the X-axis direction is used as an example for explanation) does not overlap with the orthographic projection of the first opening 100a and the orthographic projection of the second opening 100b.

[0188] In the X-axis direction, the orthographic projection of the suction part 140 does not overlap with the orthographic projection of the second opening 100b, so that the suction part 140 and the male seat 072 are spaced apart in the Z-axis direction.

[0189] In related technologies, as shown in Figure 11, Figure 11 is a schematic diagram of two installation positions of the suction unit 140 on the base 100. For ease of understanding, the male seat 072 is also shown in the figure.

[0190] Since the second opening 100b of the base 100 allows the male seat 072 to extend into the shielding chamber 080b, considering space utilization, the size of the second opening 100b is roughly matched with the size of the male seat 072, and will not be much larger.

[0191] In Figure 11(a), the suction part 140 extends from the top of the second long side wall 1312 toward the inner side of the second long side wall 1312 and is located within the second opening 100b, occupying a portion of the second opening 100b. This is manifested in that the orthographic projection of the suction part 140 overlaps with the orthographic projection of the second opening 100b in both the X-axis and Z-axis directions. The complete second opening 100b is shown by dashed lines in Figure 11(a).

[0192] In Figure 11(b), the suction part 140 forms a transverse rib spanning the first short sidewall 1321 and the second short sidewall 1322, and is located within the second opening 100b, occupying a portion of the second opening 100b. This is manifested in that the orthographic projection of the suction part 140 overlaps with the orthographic projection of the second opening 100b in both the X-axis and Z-axis directions. The complete second opening 100b in Figure 11(b) can be seen in the schematic diagram in Figure 11(a).

[0193] Because the suction part 140 occupies the second opening 100b, the male connector 072 is blocked by the suction part 140 during its movement along the negative Z-axis to engage with the female connector 071, thus preventing the male connector 072 from engaging with the female connector 071. Therefore, after installing the base 100 and before engaging the male connector 072, in Figure 11(a), the suction part 140 along with the second long side wall 1312 needs to be removed (i.e., material removal) to obtain the complete second opening 100b and the cable tray 080a; in Figure 11(b), only the suction part 140 needs to be removed to obtain the complete second opening 100b. After material removal, the male connector 072 can smoothly extend into the shielding chamber 080b through the second opening 100b and engage with the female connector 071.

[0194] It should be noted that the placement of the suction part 140 in Figure 11 necessitates a material breaking process, leading to high labor costs and reliability issues such as the risk of poor soldering, burrs lifting the cover 200, poor flatness of the solder surface, and poor strength caused by the material breaking. Furthermore, in Figure 11(a), since the second long sidewall 1312 needs to be broken off along with the material, the flatness of the solder surface, i.e., the bottom surface S1, is easily reduced, thus increasing the risk of poor soldering of the base 100.

[0195] Compared to Figure 11, in Figure 10, the suction part 140 and the male seat 072 are spaced apart in the Z-axis direction, and there is no interference between them. Because the suction part 140 is located between the top surface S2 and the bottom surface S1, the spaced separation between the suction part 140 and the male seat 072 in the Z-axis direction allows the suction part 140 to sink to the side of the male seat 072 facing the motherboard 06, and to remain spaced apart from the male seat 072. Therefore, during the process of the male seat 072 aligning with the second opening 100b and moving in the negative Z-axis direction to engage the female seat 071, the suction part 140 will not obstruct the movement of the male seat 072. In this embodiment, the suction part 140 does not require material breaking, solving the problems of high labor costs caused by material breaking, as well as reliability issues such as reduced flatness of the bottom surface S1, risk of poor soldering, material breaking burrs lifting the cover 200, poor flatness of the solder surface, and poor strength caused by material breaking.

[0196] As can be seen, in the aforementioned embodiment, the distance between the suction surface 141 and the top surface S2 is based on the standard that the suction part 140 can be moved to the side of the male seat 072 facing the motherboard 06 and spaced apart in the Z-axis direction. This embodiment does not limit the specific size of this distance.

[0197] Meanwhile, in order to avoid interference between the sunken suction part 140 and the female seat 071, which would prevent the base 100 from being installed, in FIG10, the orthographic projection of the suction part 140 and the orthographic projection of the first opening 100a do not overlap in the X-axis direction, so that the suction part 140 and the female seat 071 are spaced apart in the Z-axis direction.

[0198] The suction part 140 and the female seat 071 are spaced apart in the Z-axis direction, and there is no interference between them in the Z-axis direction. Since the suction part 140 is located between the top surface S2 and the bottom surface S1, the spaced separation between the suction part 140 and the female seat 071 in the Z-axis direction places the suction part 140 on the side of the female seat 071 facing away from the main board 06, and it is spaced apart from the female seat 071. Based on this, during the installation process where the first opening 100a of the base 100 is aligned with the female seat 071 and moved along the negative Z-axis direction, the female seat 071 does not obstruct the movement of the base 100 along the negative Z-axis direction, thus enabling the installation of the base 100.

[0199] As can be seen, in the aforementioned embodiment, the distance between the suction surface 141 and the bottom surface S1 is based on the standard that the suction part 140 can move to the side of the female seat 071 facing the male seat 072 and be spaced apart in the Z-axis direction. This embodiment does not limit the specific size of this distance.

[0200] The following description, in conjunction with Figure 10, details the specific implementation of the suction unit 140 being spaced apart from the male seat 072 and the female seat 071 in the Z-axis direction.

[0201] Please refer to Figure 10. The female connector 071 includes a female connector body 0711 and a first mating portion 0712 disposed on the female connector body 0711. The female connector body 0711 includes a bottom surface and a top surface disposed opposite to each other in the Z-axis direction. The bottom surface of the female connector body 0711 is fixed to the main board 06, and the first mating portion 0712 is disposed on the top surface of the female connector body 0711.

[0202] The male connector 072 includes a male connector body 0721 and a second mating portion 0722 disposed on the male connector body 0721. The male connector body 0721 is located on the side of the female connector 071 facing away from the main board 06, and also includes a bottom surface and a top surface facing away from each other in the Z-axis direction. The bottom surface of the male connector body 0721 faces the female connector 071, and the top surface of the male connector body 0721 faces the cover 200 and faces away from the female connector 071. The second mating portion 0722 is disposed on the top surface of the male connector body 0721, so that the second mating portion 0722 and the first mating portion 0712 can face each other and be inserted, thereby achieving the engagement of the male connector 072 and the female connector 071.

[0203] The second docking part 0722 and the first docking part 0712 are inserted to form the docking part 07a. Both the male connector 0721 and the female connector 0711 extend to the side of the docking part 07a in the X-axis direction. It should be noted that the side of the docking part 07a refers to one side of the docking part 07a in the X-axis direction, that is, the side of the docking part 07a facing the side frame 130. In this embodiment, the portion of the male connector 0721 that extends to the side of the docking part in the X-axis direction is referred to as the overflow portion 0721a.

[0204] The suction section 140 is spaced apart on the side of the docking section 07a, and the suction section 140 is spaced apart between the overflow section 0721a and the reference plane where the top surface of the female body 0711 is located.

[0205] In this embodiment, the suction part 140 is spaced between the overflow part 0721a and the reference plane where the top surface of the female body 0711 is located. This means that the suction part 140 extends to the lower part of the overflow part 0721a (towards the main body) and above the reference plane where the top surface of the female body 0711 is located (towards the back of the main board 06), and is spaced apart from the reference plane where the overflow part 0721a and the top surface of the female body 0711 are located, respectively.

[0206] When the suction portion 140 extends below and is spaced apart from the overflow portion 0721a, the suction portion 140 is spaced apart from the male seat body 0721 in the Z-axis direction, thereby achieving a Z-axis separation from the male seat 072. When the suction portion 140 extends above and is spaced apart from the reference plane containing the top surface of the female seat body 0711, the suction portion 140 is spaced apart from the female seat body 0711 in the Z-axis direction, thereby achieving a Z-axis separation from the female seat 071. In this case, in the aforementioned embodiment, the distance between the suction surface 141 and the top surface S2 and the bottom surface S1 is based on the standard that the suction portion 140 can move to the side of the docking portion and is spaced apart from the male seat body 0721 and the female seat body 0711 in the Z-axis direction.

[0207] It should be noted that in the embodiment shown in Figure 9, because the portion of the female body 0711 overflowing onto the side of the docking portion 07a in the X-axis direction is relatively small, to avoid the suction portion 140 and the docking portion 07a being too close, the suction portion 140 is not spaced above the portion of the female body 0711 that overflows onto the side of the docking portion 07a, resulting in the suction portion 140 and the female body 0711 being spaced apart in the X-axis direction. Of course, in some other embodiments, the suction portion 140 may also be spaced above the portion of the female body 0711 that overflows onto the side of the docking portion 07a, and this application embodiment does not limit this.

[0208] The shield 08 needs to leave sufficient clearance to avoid surrounding components of the BTB connector 07 to prevent scratches and other issues. This reduces the available space on the motherboard 06 for the shield 08. In this embodiment, the suction part 140 extends using the space below the overflow portion 0721a of the male connector 0721, which improves the space utilization of the shield 08 on the motherboard 06. In other words, there is no need to widen the size of the shield 08 in the X-axis direction to avoid these obstacles. This is also why the suction part 140 is recessed in this embodiment.

[0209] In some embodiments of this application, referring to FIG9, the surface of the male connector 072 facing away from the female connector 071, i.e., the top surface S2 of the male connector 072, is interference-fitted with the cover 200 of the shielding cover 08. Through the interference fit with the surface of the male connector 072 facing away from the female connector 071, the cover 200 exerts a force F2 on the male connector 072 toward the female connector 071. This force F2 can more firmly fasten the male connector 072 onto the female connector 071, thereby improving the electrical connection reliability of the BTB connector 07.

[0210] In some embodiments of this application, please refer to Figure 12, which is a schematic diagram of the structure shown in Figure 9(c) from another perspective.

[0211] In this figure, the second plate portion 120 has a second notch on the outer side of the second long side wall 1312. The second notch faces away from the second long side wall 1312, that is, towards the FPC flexible flat cable 041. The second notch is used to avoid the FPC flexible flat cable 041. In order to avoid the FPC flexible flat cable 041, the dimension of the second notch in the Y-axis direction is larger than the width of the FPC flexible flat cable 041, and the position of the second notch on the second plate portion 120 is opposite to the FPC flexible flat cable 041.

[0212] It should be noted that during the daily use of electronic devices, the FPC flexible flat cable 041 will inevitably move relative to the shielding cover 08. Because the second plate portion 120 extends to the outside of the side frame 130 and is close to the FPC flexible flat cable 041, the FPC flexible flat cable 041 is prone to rubbing against the second plate portion 120 when it moves close to the shielding cover 08. In this embodiment, the second plate portion 120 avoids the FPC flexible flat cable 041 by providing a second long sidewall 1312 facing the FPC flexible flat cable 041, thereby reducing the risk of rubbing between the FPC flexible flat cable 041 and the second plate portion 120 and improving the service life of the FPC flexible flat cable 041.

[0213] In some embodiments of this application, please refer to Figure 13, which is an enlarged schematic diagram of the structure circled by the dashed rectangle in (c) of Figure 9.

[0214] In this figure, a device is located on the outer side of the first long sidewall 1311. Correspondingly, a third notch is provided at the second end of the second inclined portion 222 on the outer side of the first long sidewall 1311, and the third notch faces the side to which the second end of the second inclined portion 222 faces. The third notch is used to avoid the device on the side to which the second end of the second inclined portion 222 faces. In order to avoid the device on the side to which the second end of the second inclined portion 222 faces, the dimension of the third notch in the Y-axis direction is larger than the dimension of the device in the Y-axis direction, and the third notch is opposite to the device.

[0215] It should be noted that the installation of the shield 08 requires sufficient clearance between it and the surrounding components of the BTB connector 07 to reduce the risk of scratches. However, in Figure 13, because the second end of the second inclined portion 222 gradually tilts away from the side frame 130, the distance between the second inclined portion 222 and these surrounding components is relatively close. To meet the clearance requirement, in this embodiment, the second end of the second inclined portion 222 is provided with a third notch facing the side towards which the second end of the second inclined portion 222 is facing, thereby avoiding the components on the side towards which the second end of the second inclined portion 222 is facing, thus enabling the shield 08 to meet the clearance requirement.

[0216] It should be noted that Figure 13 illustrates an example of a device located on the outer side of the first long sidewall 1311 of the side frame 130. In other embodiments, the device may also be located on the outer side of other sidewalls, in which case the position of the third notch is adjusted accordingly.

[0217] In addition, this application embodiment also provides another shield 08.

[0218] For example, please refer to Figure 14, which is a structural schematic diagram of the base 100 of another shielding cover provided in an embodiment of this application. The cover 200 of the shielding cover is not shown in the figure. The cover 200 of the shielding cover can be adapted to the relevant description of the cover 200 of the shielding cover shown in Figure 4, and will not be repeated here. The differences of the base 100 will be explained in detail below.

[0219] Unlike the base 100 in Figure 4, in the base 100 shown in Figure 14, the suction part 140 extends from the top of the side frame 130 toward the inside of the side frame 130. The suction surface 141 of the suction part 140 is located inside the top surface S2, that is, the suction surface 141 of the suction part 140 is part of the top surface S2. The second opening 100b is distributed side by side on the side of the suction surface 141 facing away from the side frame 130.

[0220] In this embodiment, when the second openings 100b are arranged side-by-side on the side of the suction surface 141 facing away from the side frame 130, the orthogonal projections of the second openings 100b and the suction portion 140 in the Z-axis direction do not overlap. Since the male connector 072 extends into and engages with the female connector 071 through the second openings 100b, the orthogonal projections of the male connector 072 and the suction portion 140 in the Z-axis direction also do not overlap. In this case, the suction portion 140 is spaced apart from the male connector 072 in the X-axis direction. Therefore, during the process of aligning the male connector 072 with the second openings 100b and moving it along the negative Z-axis direction for engagement, the suction portion 140 does not obstruct the movement of the male connector 072. Thus, in this embodiment, the suction portion 140 does not require material breaking, solving the problems of high labor costs caused by material breaking, as well as reliability issues such as the risk of poor soldering, material breaking burrs lifting the cover 200, poor flatness of the solder surface, and poor strength caused by material breaking.

[0221] Meanwhile, since the suction surface 141 is on the top surface S2 and the first opening 100a is located on the bottom surface S1, the orthographic projections of the suction part 140 and the first opening 100a on the bottom surface S1 do not overlap in the X-axis direction, thus separating the suction part 140 from the female seat 071 in the Z-axis direction. Based on this, during the installation process of the base 100 moving along the negative Z-axis direction with the first opening 100a aligned with the female seat 071, the female seat 071 does not obstruct the movement of the base 100 along the negative Z-axis direction, thereby enabling the installation of the base 100.

[0222] Optionally, the suction portion 140 may extend from the top of the first short sidewall 1321 toward the inside of the first short sidewall 1321. Of course, in some other embodiments, the suction portion 140 may also be obtained by extending inward from other sidewalls of the side frame 130, and this application embodiment does not limit this.

[0223] It should be noted that, because the first short sidewall 1321 is a short side, its dimensions in the X-axis direction are relatively limited. Therefore, the fastening hole 130a has no space to move towards the edge of the first short sidewall 1321 in the X-axis direction. Based on this, in order to meet the required spacing between the fastening hole 130a and the upper and lower edges of the first short sidewall 1321, the suction part 140 is not suitable to sink into the first short sidewall 1321. Therefore, in this embodiment, the suction part 140 extends from the top of the first short sidewall 1321 towards the inside of the first short sidewall 1321. Of course, in some other embodiments, if the fastening hole 130a is not provided on the first short sidewall 1321, the suction part 140 can also extend from the top of the first short sidewall 1321 towards the inside of the first short sidewall 1321. This application does not limit this aspect.

[0224] It should also be noted that when the suction part 140 extends from the top of the first short side wall 1321 toward the inside of the first short side wall 1321, the suction surface 141 and the second opening 100b of the suction part 140 are arranged side by side in the X-axis direction, occupying more space in the X-axis direction. Therefore, the shield 08 of this embodiment is suitable for electronic devices in which the BTB connector 07 and surrounding devices have sufficient spacing in the X-axis direction.

[0225] In Figure 14, since the upper surface of the first plate portion 110 forms the top surface S2 of the base 100, the suction portion 140 can be considered as part of the first plate portion 110, and the suction surface 141 of the suction portion 140 is part of the upper surface of the first plate portion 110. Since the upper surface of the first plate portion 110 belongs to the top surface S2, the suction surface 141 of the suction portion 140 is naturally located within the top surface S2 of the base 100.

[0226] Specifically, when the suction part 140 extends from the top of the first short side wall 1321 toward the inside of the first short side wall 1321, the suction part 140 is specifically the part of the first plate part 110 on the side of the second through hole near the first short side wall 1321, that is, the part of the first plate part 110 between the outer wall surface of the first short side wall 1321 and the second through hole.

[0227] In the embodiment shown in Figure 14, since the first long sidewall 1311 does not sink, unlike the shield 08 shown in Figure 4, more fastening holes 130a can be opened on the first long sidewall 1311, such as three or four, so as to make the fastening force greater.

[0228] In addition, this application embodiment also provides another shield 08.

[0229] For example, please refer to Figure 15, which is a structural schematic diagram of the base 100 of another shielding cover provided in an embodiment of this application. The cover 200 of the shielding cover is not shown in the figure. The cover 200 of the shielding cover can be adapted to the relevant description of the cover 200 of the shielding cover shown in Figure 4, and will not be repeated here. The differences of the base 100 will be explained in detail below.

[0230] Unlike the base 100 in the embodiment shown in FIG4, in the base 100 shown in FIG15, the suction part 140 extends from the bottom end of the side frame 130 toward the outside of the side frame 130, and the non-suction surface 141 of the suction part 140 is inside the bottom surface S1.

[0231] Since the suction part 140 extends from the bottom end of the side frame 130 towards the outside of the side frame 130, the suction part 140 is on the outside of the side frame 130, while the second opening 100b is located on the inside of the side frame 130. Obviously, the orthographic projection of the second opening 100b and the suction part 140 in the Z-axis direction does not overlap. Since the male seat 072 extends into the shielding chamber 080b through the second opening 100b and engages with the female seat 071, the orthographic projection of the male seat 072 and the suction part 140 in the Z-axis direction also does not overlap. In this case, the suction part 140 is spaced apart from the male seat 072 in the X-axis direction. Based on this, during the process of aligning the male connector 072 with the second opening 100b and moving it along the negative Z-axis for engagement, the suction part 140 will not interfere with the male connector 072, and the suction part 140 will not obstruct the movement of the male connector 072. Therefore, in this embodiment, the suction part 140 does not require material breaking, solving the problems of high labor costs caused by material breaking, as well as reliability issues such as reduced flatness of the bottom surface S1, risk of cold solder joints, material breaking burrs lifting the cover 200, poor flatness of the solder surface, and poor strength caused by material breaking. In addition, in this embodiment, the orthogonal projections of the suction part 140 and the second opening 100b do not overlap in the X-axis direction, and the suction part 140 and the male connector 072 are spaced apart in the Z-axis direction.

[0232] Meanwhile, the first opening 100a is also located inside the side frame 130. Obviously, the orthogonal projection of the first opening 100a and the suction part 140 on the outside of the side frame 130 in the Z-axis direction does not overlap. Since the female seat 071 extends into the shielding chamber 080b through the first opening 100a, the orthogonal projections of the female seat 071 and the suction part 140 in the Z-axis direction also do not overlap. In this case, the suction part 140 is spaced apart from the female seat 071 in the X-axis direction. Based on this, during the installation process of the base 100 moving along the negative Z-axis direction with the first opening 100a aligned with the female seat 071, the female seat 071 will not obstruct the movement of the base 100 along the negative Z-axis direction, thus enabling the installation of the base 100.

[0233] Furthermore, in this embodiment, the suction portion 140 extends from the bottom end of the side frame 130 toward the outer side of the side frame 130, providing space for the cover 200 in the Z-axis direction so that the cover 200 can extend to the outer side of the side frame 130 for fastening. Of course, in some other embodiments, the suction portion 140 may also move upward on the side frame 130 without interfering with the cover 200; this embodiment does not limit this.

[0234] Alternatively, the suction portion 140 may extend from the bottom end of the first short side wall 1321 toward the outside of the first short side wall 1321.

[0235] It should be noted that when the suction part 140 extends from the bottom end of the first short side wall 1321 toward the outside of the first short side wall 1321, the non-suction surface 141 of the suction part 140 and the first opening 100a are arranged side by side in the Y-axis direction, occupying more space in the Y-axis direction. Therefore, the shield 08 of this embodiment is suitable for electronic devices in which the BTB connector 07 and surrounding devices have sufficient spacing in the Y-axis direction.

[0236] Because the first short sidewall 1321 is a short side, its dimensions in the X-axis direction are relatively limited. Therefore, the fastening hole 130a has no space to move towards the edge of the first short sidewall 1321 in the X-axis direction. Based on this, in order to meet the required spacing conditions between the upper and lower edges of the fastening hole 130a and the first short sidewall 1321, the suction part 140 is not suitable for moving upwards on the first short sidewall 1321. Therefore, in this embodiment, the suction part 140 extends from the bottom end of the first short sidewall 1321 towards the outside of the first short sidewall 1321.

[0237] In the embodiment shown in Figure 15, since the first long sidewall 1311 does not move upward, unlike the shield 08 shown in Figure 4, more fastening holes 130a can be opened on the first long sidewall 1311, such as three or four, so as to make the fastening force greater.

[0238] Of course, in some other embodiments, the suction portion 140 may also be obtained by extending outward from the bottom end of other sidewalls of the side frame 130, and this application embodiment does not limit this. For example, FIG16 shows the case where the suction portion 140 extends from the bottom end of the first long sidewall 1311 toward the outside of the first long sidewall 1311.

[0239] For example, please refer to Figure 16, which is a structural schematic diagram of the base 100 of another shielding cover provided in an embodiment of this application. The cover 200 of the shielding cover is not shown in the figure. The cover 200 of the shielding cover can be adapted to the relevant description of the cover 200 of the shielding cover shown in Figure 4, and will not be repeated here. The differences of the base 100 will be explained in detail below.

[0240] Unlike the base 100 in the embodiment shown in FIG15, in the base 100 shown in FIG16, the suction part 140 extends from the bottom end of the first long side wall 1311 toward the outside of the first long side wall 1311, and the non-suction surface 141 of the suction part 140 is also in the bottom surface S1.

[0241] In this embodiment, the suction part 140 also does not require material breaking, which solves the problem of high labor costs caused by material breaking, as well as reliability problems such as reduced flatness of the bottom surface S1, risk of poor soldering, material breaking burrs lifting the cover 200, poor flatness of the solder surface, and poor strength caused by material breaking. For a detailed analysis, please refer to the description of the embodiment shown in Figure 15.

[0242] It should be noted that in the embodiment shown in FIG16, when the suction part 140 extends from the bottom end of the first long side wall 1311 toward the outside of the first long side wall 1311, the non-suction surface 141 of the suction part 140 and the first opening 100a are arranged side by side in the X-axis direction, occupying more space in the X-axis direction. Therefore, the shield 08 of this embodiment is suitable for electronic devices in which the BTB connector 07 and surrounding devices have sufficient spacing in the X-axis direction.

[0243] Furthermore, compared to the pick-up portion 140 shown in Figure 15, since the first long sidewall 1311 extends in the length direction, the pick-up portion 140 can utilize the length advantage of the first long sidewall 1311 to form a pick-up surface 141 that meets the SMT pick-up requirements and whose length is significantly greater than its width. The smaller the width of the pick-up surface 141, the shorter the distance the pick-up portion 140 extends to the outside of the first long sidewall 1311, and the lower the risk of the pick-up portion 140 rubbing against the devices on the outside of the first long sidewall 1311.

[0244] In this embodiment, the suction part 140 extends from the bottom end of the first long sidewall 1311 towards the outer side of the first long sidewall 1311, providing space for the cover 200 in the Z-axis direction so that the cover 200 can extend to the outer side of the side frame 130 for fastening. Of course, in some other embodiments, without interfering with the cover 200, the suction part 140 can also move upward on the first long sidewall 1311. Furthermore, in order to provide a fastening hole 130a on the first long sidewall 1311, the suction part 140 can occupy a portion of the first long sidewall 1311 in the Y-axis direction to reserve a fastening hole portion 131a similar to that described above. Since the first long sidewall 1311 in Figure 16 has not moved upward, more fastening holes 130a can be opened on the first long sidewall 1311, for example, three or four, to make the fastening force greater. This application embodiment does not limit this.

[0245] In Figure 16, since the lower plate surface of the second plate portion 120 forms the bottom surface S1 of the base 100, the suction portion 140 can be considered as a part of the second plate portion 120, and the suction surface 141 of the suction portion 140 is a part of the lower plate surface of the second plate portion 120. When the suction portion 140 extends from the bottom end of the first short side wall 1321 to the outside of the first short side wall 1321, the suction portion 140 is specifically the part of the second plate portion 120 on the outside of the first short side wall 1321.

[0246] Finally, it should be noted that specific features, structures, etc., described in this specification can be combined in any suitable manner in one or more embodiments or examples. Furthermore, the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
