Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to an electronic device. Background Technology

[0002] With the development of technology, people have increasingly higher requirements for the exquisite appearance of mobile phones and other electronic devices.

[0003] Electronic devices typically include a housing and a card tray. The housing has a frame with a card slot. The card tray consists of a card tray cap and a card tray body. The card tray cap is connected to the card tray body and is located within the card slot. The card tray body carries the electronic card and is installed inside the electronic device. Currently, the frame and card tray cap are usually obtained through injection molding. Because both the frame and the card tray cap are injection molded, when the card tray cap is placed within the card slot, the gap between the card tray cap and the card slot is too large along the length of the card tray cap. This results in a poor appearance and affects the user experience. Summary of the Invention

[0004] This application provides an electronic device that can reduce the single-sided gap between the position of the card holder on the outer surface and the circumferential outer wall of the frame along the length direction of the card holder, thereby improving the appearance refinement of the electronic device and enhancing the user experience.

[0005] This application provides an electronic device. The electronic device includes:

[0006] The housing includes a frame with a card slot. The card slot includes a first hole segment, which is disposed near the circumferential outer wall of the frame. The first hole segment is an outwardly expanding structure that expands toward the circumferential outer wall of the frame.

[0007] A card tray, including a card tray cap, the card tray cap including a first mating portion and a second mating portion in the thickness direction, the projection of the first mating portion onto the second mating portion covering the second mating portion; the second mating portion is located at one end of the card insertion hole near the circumferential inner wall of the frame, the first mating portion is located at one end of the card insertion hole near the circumferential outer wall of the frame, and the end face of the first mating portion facing away from the second mating portion forms the outer surface of the card tray cap.

[0008] The height of the first hole section is H1, and the height of the end face where the first mating part and the second mating part meet within the first hole section is H2, where H2 is greater than or equal to one-third of H1.

[0009] In this embodiment, with the frame structure and card holder thickness remaining unchanged, by setting H2 to be greater than or equal to one-third of H1, the contact position between the first and second mating parts can be made closer to the peripheral outer wall of the frame. This achieves an outward shift of the contact position between the first and second mating parts within the first hole segment. Since the first hole segment is an outward-expanding structure towards the peripheral outer wall of the frame, when the single-sided gap between the contact position of the first and second mating parts and the peripheral outer wall of the frame is controlled to the tolerance limit along the length direction of the card holder, the closer the contact position of the first and second mating parts is to the peripheral outer wall of the frame within the first hole segment, the smaller the single-sided gap between the position of the card holder on the outer surface and the peripheral outer wall of the frame. Therefore, by shifting the contact position of the first and second mating parts outward within the first hole segment, this embodiment can reduce the single-sided gap between the position of the card holder on the outer surface and the peripheral outer wall of the frame along the length direction of the card holder, thereby improving the aesthetics of the electronic device and enhancing the user experience.

[0010] The projection of the first mating part onto the second mating part covers the second mating part; therefore, the first mating part serves as the effective mating section between the card tray cap and the frame. Because the contact point between the first and second mating parts is shifted outward within the first hole section, the thickness of the first mating part can be reduced, thereby decreasing the effective mating hole height between the card tray cap and the frame. This reduces the friction area between the card tray and the frame during insertion and removal, solving the problem of card tray insertion / removal difficulties or excessive tightness caused by manufacturing process tolerances, and improving the user experience.

[0011] In some embodiments, H2 is greater than or equal to half of H1 and less than or equal to two-thirds of H1. This configuration can further reduce the single-sided gap between the position of the card holder on the outer surface and the circumferential outer wall of the frame along the length direction of the card holder. At the same time, it can also prevent the first mating part from protruding from the circumferential outer wall of the frame, which would affect the smoothness of the electronic device on the peripheral surface and improve the user's feel.

[0012] In some embodiments, the cassette cap is configured to be formed by injection molding;

[0013] The end face that connects with the first mating part and the second mating part is coplanar with the parting surface of the mold.

[0014] At this point, the outward shift of the contact point between the first and second mating parts within the first hole section can be understood as the outward shift of the parting surface within the first hole section. This allows the contact point between the first and second mating parts to shift outward within the first hole section when the card holder cap is positioned within the first hole section. Furthermore, with the card holder cap's thickness remaining constant, the outward shift of the contact point between the first and second mating parts within the first hole section also reduces the draft height of the slider in the mold, facilitating card holder cap demolding.

[0015] In some embodiments, the wall of the first hole segment is inclined in the direction away from the card holder cap;

[0016] The circumferential sidewall of the first mating part includes a first inclined surface, the inclination direction of which is opposite to the inclination direction of the hole wall.

[0017] The first inclined surface can be considered as the first draft angle of the card tray cap. Thus, when the card tray is injection molded, the first draft angle of the card tray cap facilitates its removal from the mold. In this embodiment, by shifting the position where the first mating part and the second mating part meet outward within the first hole segment, the single-sided gap between the card tray cap's position on the outer surface and the circumferential outer wall of the frame can be reduced, thereby improving the aesthetic refinement of the electronic device and enhancing the user experience.

[0018] In some embodiments, the wall of the first hole segment is inclined in the direction away from the card holder cap;

[0019] The circumferential sidewall of the first mating part includes a vertical surface, which is perpendicular to the outer surface. In this way, without changing the structure of the frame or the thickness of the card holder, the single-sided gap between the position of the card holder on the outer surface and the circumferential outer wall of the frame can be reduced, thereby improving the appearance and refinement of the electronic device.

[0020] In some embodiments, the second mating portion is in contact with a portion of the end face of the first mating portion, and the portion of the end face of the first mating portion not in contact with the second mating portion forms an interface.

[0021] By setting the interface, when forming the card holder through injection molding, it is only necessary to align the mold core and the slider at the parting surface (i.e., horizontal alignment), without the need for vertical alignment, thus reducing the difficulty of alignment. When the injection material for the card holder is injected into the mold, it will move to the position where the mold core and slider are misaligned. The injection material at this position serves as an effective structure of the first mating part after molding, eliminating the need for manual removal after demolding. Therefore, this application, through the interface design, can reduce circumferential burrs on the card holder cap formed during injection molding, improve the yield of the card holder cap, and reduce the manufacturing cost of the card holder.

[0022] In some embodiments, the interface is an annular structure surrounding the second mating portion, so that the interface is a closed annular structure.

[0023] Compared to a non-ringed structure at the interface, when the interface is a closed ring structure, burrs can be avoided at various circumferential positions of the card holder formed during injection molding, further improving the yield of the card holder and reducing the manufacturing cost of the card holder.

[0024] In some embodiments, the width of the interface is e, which is greater than or equal to 0.03 mm, and the direction of the width of the interface is parallel to the length direction of the card holder cap.

[0025] By limiting the value of the interface width e, the interface width e can be limited to a more suitable range, so as to ensure that the interface settings can effectively prevent the card cap from generating fringe in the circumferential direction.

[0026] In some embodiments, the thickness of the first mating part is H3, and the thickness of the second mating part is H4, where H4 is greater than or equal to H3, so that the first mating part occupies a larger proportion in the thickness direction of the card holder cap. Thus, when the card holder cap is located in the first hole section, the second mating part will occupy more space in the hole height direction of the first hole section compared to the first mating part, allowing the first mating part to be closer to the circumferential outer wall of the frame within the first hole section. This way, without changing the structure of the frame or the thickness of the card holder cap, the end faces where the first and second mating parts meet can be closer to the circumferential outer wall of the frame, effectively shifting the position where the first and second mating parts meet outward within the first hole section.

[0027] In some embodiments, H3 is greater than 0.2 mm and less than or equal to 0.4 mm.

[0028] In this embodiment of the application, by limiting H3 to greater than 0.2 mm and less than or equal to 0.4 mm, while ensuring that the current mold process capability can produce a card holder that meets the requirements, it can not only reduce the risk of the card holder getting stuck in the card insertion hole and avoid problems such as the card holder not being easy to insert or remove or being too tight, but also ensure that the position where the first mating part and the second mating part meet has a large outward displacement in the first hole section, effectively reducing the single-sided gap between the position of the card holder on the outer surface and the circumferential outer wall of the frame.

[0029] In some embodiments, there is a clearance space between the second mating part and the hole wall of the first hole segment, and the second mating part has a clearance portion on the side adjacent to the first mating part, the clearance portion being used to increase the clearance space in the length direction of the card holder cap.

[0030] This embodiment, by setting up a clearance portion, can further increase the clearance space between the first hole segment and the second mating portion at the position of the circumferential inner wall near the frame, so as to further reduce the risk of jamming during the insertion and removal of the card tray and further improve the smoothness of the insertion and removal of the card tray.

[0031] In some embodiments, the second mating part is provided with a second inclined surface on the circumferential sidewall. The second inclined surface has a first side and a second side. The first side is connected to the first mating part, and the second side is inclined relative to the first side toward the center of the first hole segment.

[0032] The second slope forms a clearance section.

[0033] By tilting the second side, the circumferential dimension of the second mating part can be gradually reduced in the direction from the first side to the second side, thereby increasing the clearance space between the first hole segment and the second mating part at the position of the circumferential inner wall near the frame.

[0034] Compared to the second mating part having a circumferential sidewall perpendicular to the end face of the first mating part, the second inclined surface can reduce stress concentration at the intersection of the circumferential sidewall of the second mating part and the end face of the first mating part, thus ensuring a longer service life for the card holder.

[0035] In some embodiments, the circumferential sidewall of the second mating part is perpendicular to the end face of the first mating part;

[0036] The circumferential sidewall of the second mating part forms a clearance portion, which also increases the clearance space between the first hole segment and the second mating part at the position of the circumferential inner wall near the frame.

[0037] In some embodiments, the housing further includes a mounting plate, a frame surrounding the periphery of the mounting plate and in contact with the mounting plate; the card slot further includes a second hole segment communicating with the first hole segment, the second hole segment being disposed near the circumferential outer wall of the frame.

[0038] The cap also includes a third mating part, which is connected to the end of the second mating part away from the first mating part; at least a portion of the third mating part is located within the second hole segment;

[0039] The card tray also includes a card tray body, which is mounted on the mounting plate and connected to the third mating part to enable the card tray to be mounted on the housing.

[0040] In some embodiments, the electronic device further includes a card holder disposed on a mounting plate, the card holder having an open receiving cavity, a card tray body disposed within the receiving cavity, and the card tray body being detachable to enable a detachable connection of the card tray body to the mounting plate, so as to facilitate the user to insert and remove the card tray.

[0079] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0080] This application provides an electronic device, which may include, but is not limited to, mobile phones, tablets (i.e., pads), smart wearable devices, and other electronic devices with a SIM card tray. The mobile phone may be a foldable phone. Alternatively, the mobile phone may be a non-foldable phone. A non-foldable phone may also be a candybar phone. The smart wearable device may include, but is not limited to, smartwatches.

[0081] Figure 1 and Figure 2 The images show an overall view of an electronic device 100 from different perspectives. The electronic device 100 is a non-folding mobile phone.

[0082] The following example uses a non-foldable phone, combined with... Figure 1 and Figure 2 The structure of the electronic device 100 is described in detail.

[0083] For ease of description, a coordinate system is established for the electronic device 100. The length direction of the electronic device 100 is the Y-direction, the width direction is the X-direction, and the thickness direction is the Z-direction. Any two of the Y, X, and Z directions are perpendicular to each other.

[0084] See Figure 1 and Figure 2 The electronic device 100 includes a housing 1. The housing 1 provides a mounting platform for some components that can serve as the electronic device 100.

[0085] See Figure 2 When the electronic device 100 is a mobile phone, in some embodiments, the electronic device 100 may also include a back cover 2. The back cover 2 is applied to and attached to one side of the housing 1.

[0086] See also Figure 2 The electronic device 100 also includes a display screen 3. The display screen 3 and the back cover 2 are mounted on opposite sides of the housing 1 and connected to the housing 1, thereby enabling the display screen 3 and the back cover 2 to be installed and fixed on the housing 1. The display screen 3 can provide the electronic device 100 with a display interface and an interactive interface with the user.

[0087] For a mobile phone, since the housing 1 is sandwiched between the display screen 3 and the back cover 2, the housing 1 can be understood as the mid-frame of the mobile phone.

[0088] Figure 3 An exploded view of an electronic device 100 is shown. This electronic device 100 is still a non-foldable phone. Furthermore, in... Figure 3 The diagram only shows some components of the electronic device 100 and does not constitute a limitation on the structure of the electronic device 100. For example, Figure 3 The image shows the housing 1, display screen 3, back cover 2, and circuit board.

[0089] See Figure 3The housing 1 includes interconnected frame 11 and mounting plate 12. For a mobile phone, mounting plate 12 can be understood as the middle plate of the housing 1 (middle frame). Frame 11 can be a square-ring structure formed by multiple side frames 11 joined end-to-end. For example, frame 11 may include a top frame 11a, a left frame 11b, a bottom frame 11c, and a right frame 11d. The top frame 11a and bottom frame 11c are opposite each other in the length direction (Y direction) of the electronic device 100. The left frame 11b and right frame 11d are opposite each other in the width direction (X direction) of the electronic device 100.

[0090] The frame 11 surrounds the peripheral edge of the middle plate and connects to the peripheral edge of the middle plate. When the rear cover 2 and the display screen 3 are mounted on one side of the mounting plate 12 in the thickness direction of the electronic device 100 and connected to the frame 11, the rear cover 2 covers and connects to one side of the housing 1. The display screen 3 is mounted on the other side of the mounting plate 12 in the thickness direction of the electronic device 100 and connected to the frame 11, thereby covering and connecting the display screen 3 to the other side of the housing 1.

[0091] It should be noted that, see again Figure 2 When the back cover 2 and the display screen 3 are both covered and connected to the housing 1, the top frame 11a, the left frame 11b, the bottom frame 11c and the right frame 11d are partially exposed outside the electronic device 100, forming the exterior surface 711 of the electronic device 100 together with the display screen 3 and the back cover 2.

[0092] When the rear cover 2 is installed and connected to one side of the housing 1, the rear cover 2 and the housing 1 form a cavity for housing components such as the circuit board, battery 5, and camera module 6 of the electronic device 100. The circuit board includes a main circuit board 4. The main circuit board 4 typically houses modules such as a processor module, a system-on-a-chip (SoC), a storage module, a communication module, a radio frequency module, and a power management module. The main circuit board 4 is located within the cavity formed by the rear cover 2 and the housing 1, and is situated on the side of the cavity adjacent to the top edge 11a. The display screen 3 can be electrically connected to the main circuit board 4 and can be used to display various information and receive user input.

[0093] See also Figure 3 The circuit board also includes a sub-circuit board, which typically carries modules such as electrical connectors and speakers. The sub-circuit board is located within the accommodating cavity formed by the rear cover 2 and the housing 1, and is located on the side of the accommodating cavity adjacent to the bottom frame 11c.

[0094] When the battery 5 is housed within the cavity formed by the rear cover 2 and the housing 1, it can be located between the main circuit board 4 and the sub-circuit board. The positions of the camera module 6 and other components within the cavity can be referenced from the configurations in existing mobile phones and other electronic devices 100, and are not further limited here.

[0095] In some embodiments, when the display screen 3 covers and is connected to the other side of the housing 1, the display screen 3 and the housing 1 can also form another accommodating cavity to accommodate devices such as the camera module 6. Similarly, the position of the camera module 6 within the accommodating cavity formed by the display screen 3 can be seen from the configuration in existing mobile phones and other electronic devices 100, and is not further limited here.

[0096] Figure 4 Another exploded view of the electronic device 100 provided in the embodiments of this application. Figure 5 It shows Figure 2 A partial schematic diagram of the electronic device 100.

[0097] See Figure 4 and Figure 5 The frame 11 has a card slot 113. The card slot 113 can penetrate the inner circumferential wall 112 and the outer circumferential wall 111 of the frame 11. That is, the card slot 113 is a through hole on the frame 11. Part of the outer circumferential wall 111 of the frame 11 forms the exterior surface 711 of the electronic device 100. Part of the inner circumferential wall 112 of the frame 11 is located inside the electronic device 100.

[0098] The electronic device 100 also includes a card tray 7. The card tray 7 carries an electronic card that is installed in the card slot 113. For example, the electronic card can be a SIM (Subscriber Identity Module) card, etc. When the card tray 7 carries a SIM card and is installed in the card slot 113, the electronic device 100 can have network communication capabilities. Alternatively, in some embodiments, the electronic card can also be a memory card. When the card tray 7 carries a memory card and is installed in the card slot 113, the storage capacity of the electronic device 100 can be expanded.

[0099] In some embodiments, the card slot 113 may be located on the left frame 11b so that the card tray 7 can be installed in the left frame 11b and the electronic device 100. However, this does not constitute a limitation on the location of the card slot 113 on the frame 11.

[0100] Figure 6 A schematic diagram of the structure of another electronic device 100 is shown.

[0101] See Figure 6 In other embodiments, the card slot 113 may also be located on the bottom frame 11c so that the card tray 7 can be installed in the bottom frame 11c and the electronic device 100.

[0102] The following section uses the example of the cassette 7 being installed in the left side frame 11b and the electronic device 100 to further illustrate the structure of the electronic device 100.

[0103] Figure 7A schematic diagram of the structure of a Cato 7 is shown.

[0104] See Figure 7 The card tray 7 includes a card tray cap 71 and a card tray body 72. The card tray cap 71 is connected to the card tray body 72. The card tray body 72 refers to the structure of the card tray 7 excluding the card tray cap 71. To enable the card tray 7 to hold electronic cards, the card tray body 72 has a card slot 721. The shape of the card slot 721 matches the shape of the electronic card so that the electronic card can be fixed in the card slot 721. In this way, when the card tray body 72 passes through the card insertion hole 113 and is mounted on the mounting plate 12, the electronic card can be installed in the electronic device 100. At this time, the card tray cap 71 is located in the card insertion hole 113.

[0105] It should be noted that the matching of the shape of A with the shape of B mentioned in the embodiments of this application can be understood as the shape of A being the same as or similar to the shape of B. For example, the matching of the shape of the card slot 721 with the shape of the electronic card mentioned above can be understood as the shape of the card slot 721 being the same as or similar to the shape of the electronic card. Similar interpretations will be made in the following text.

[0106] like Figure 7 As shown, the card tray body 72 may have two card slots 721, which may be arranged along the width direction of the electronic device 100. Alternatively, the two card slots 721 may also be arranged along the length direction of the electronic device 100 on the card tray body 72. Figure 7 This does not constitute a limitation on the number of card slots 721 on the card tray 7. For example, in some embodiments, the card tray body 72 may also have one card slot 721.

[0107] Figure 8 It indicates Figure 5 A partial cross-sectional view in the AA direction.

[0108] See Figure 8 The card holder cap 71 is located inside the card insertion hole 113. The card holder body 72 is mounted on the mounting plate 12 and connected to the card holder cap 71 to enable the card holder 7 to be mounted on the housing 1.

[0109] Specifically, the card tray body 72 is detachably mounted on the mounting plate 12 to facilitate user insertion and removal of the card tray 7. When the card tray body 72 is mounted on the mounting plate 12, it is connected to the circuit board. For example, when the housing 1 is mounted on the left side frame 11b, the card tray body 72 is connected to the main circuit board 4. As another example, when the housing 1 is mounted on the left side frame 11b, the card tray body 72 is connected to the secondary circuit board.

[0110] The electronic device 100 also includes a card holder. The card holder is disposed on the mounting plate 12. The card holder has an open receiving cavity. The card tray body 72 is disposed within the receiving cavity and is detachable to enable a detachable connection of the card tray body 72 to the mounting plate 12, so as to facilitate the user to insert and remove the card tray 7.

[0111] For example, when the card tray body 72 is disposed in the receiving cavity, the card tray body 72 can be elastically engaged with the card holder, so that the card tray body 72 can be detached from the mounting plate 12 by the card holder.

[0112] See you again Figure 5 The electronic device 100 may have a pin hole 117 on its periphery. The pin hole 117 may be located on the frame 11, or it may be located on the card tray cap 71. If the user needs to remove the card tray 7 from the electronic device 100, the user can place the end of the pin in the pin hole 117 so that the card tray cap 71 extends out of the card insertion hole 113, making it convenient for the user to remove the card tray 7.

[0113] It should be noted that the principle of the needle being placed in the needle hole 117 so that the card holder cap 71 extends out of the card insertion hole 113 can be determined based on the structure of existing mobile phones, and will not be repeated in this embodiment.

[0114] The card tray cap 71 and the card tray body 72 can be detachably connected. Alternatively, the card tray cap 71 and the card tray body 72 can be integrally connected, making the card tray 7 a single structural component. The connection between the card tray cap 71 and the card tray body 72 can be determined based on the structure of the card tray in existing electronic devices, and will not be elaborated further in this application.

[0115] Currently, card holder caps are typically obtained by injection molding. The mold can be a plastic mold, etc. The frame 11, especially the portion with at least the card insertion hole 113, is also typically obtained by injection molding. Since both the frame 11 and the card holder cap are injection molded, when the card holder cap is placed inside the card insertion hole 113, the single-sided gap between the card holder cap and the card insertion hole 113 in the length direction is relatively obvious.

[0116] With the development of technology, people have increasingly higher requirements for the appearance and sophistication of mobile phones and other electronic devices. When the gap between the card tray cap and the card slot 113 is relatively obvious on one side along the length, it will make the appearance and sophistication of the electronic device 100 poor, affecting the user experience.

[0117] Therefore, the inventors of this application have studied and analyzed the reasons for the excessive unilateral gap between the card holder cap and the card insertion hole 113.

[0118] Figure 9a A schematic diagram of a card holder 7a and a frame 11 in the related art is shown. Figure 9b It shows Figure 9aEnlarged view at point a. Figure 10 A schematic diagram of a card holder 7, a frame 11, and a mold 200 in the related art is shown.

[0119] See Figures 9a to 10 Research has shown that, to facilitate the ejection of the card holder cap 71a from the mold 200, the card holder cap 71a typically also has a first draft angle 712. The angle α between the first draft angle 712 and the demolding direction of the mold 200 can be called the draft angle of the card holder cap 71a. By setting the draft angle on the card holder cap 71a, a smaller structure can be formed at the end of the card holder cap 71a away from the card holder body 72a, while a larger structure can be formed at the end closer to the card holder body 72a, thus facilitating the ejection of the card holder cap 71a from the mold 200. The draft angle of the card holder cap 71a is typically between 1° and 3°.

[0120] The following is combined Figure 9a and Figure 10 The draft angle and demolding direction are explained.

[0121] See Figure 10 The mold 200 typically includes a mold core 210 and a slider 220. After the mold core 210 and slider 220 are closed, they form a cavity 230 that matches the shape of the card holder 7. The injection molding material of the card holder cap 71a fills the cavity 230, and after the injection molding material forms the card holder cap 71a, the portion of the card holder cap 71a with the first draft angle 712a is located within the slider 220, while the remaining portion of the card holder cap 71a is located within the mold core 210. The mold core 210 and slider 220 part around the periphery of the card holder cap 71a; therefore, the parting surface 240 of the mold 200 is also located around the periphery of the card holder cap 71a. When the mold core 210 and slider 220 are closed, the surfaces of the mold core 210 and slider 220 that meet are the parting surface 240. The slider 220 moves along the V direction to move away from the mold core 210 and part from the mold core 210, allowing the card holder cap 71a to be demolded. The V direction can be regarded as the demolding direction of mold 200.

[0122] See you again Figure 9a Research revealed that along the height of the card insertion hole 113, the card insertion hole 113 includes a first hole segment 114 and a second hole segment 115 communicating with the first hole segment 114. The first hole segment 114 is located near the circumferential outer wall 111 of the frame 11. The second hole segment 115 is located near the circumferential outer wall 111 of the frame 11. Furthermore, a stepped structure is formed between the first hole segment 114 and the second hole segment 115 in the card insertion hole 113. When the card tray body 72a is installed on the mounting plate 12 through the card insertion hole 113, a portion of the card tray cap 71a will be located within the first hole segment 114, and another portion will be located within the second hole segment 115.

[0123] See you again Figure 9bTo facilitate the ejection of the frame 11 from the mold 200, a second draft angle 116 is typically provided on the wall of the first hole section 114 in related technologies. The angle β between the second draft angle 116 of the first hole section 114 and the demolding direction of the mold 200 can be called the draft angle. By setting the draft angle, it is easier for the frame 11 to eject from the mold 200. The draft angle of the frame 11 is also between 1° and 3°.

[0124] Due to the presence of the second draft slope 116, the first hole segment 114 will form an outwardly expanding structure that expands towards the circumferential outer wall 111 of the frame 11. That is, the diameter of the first hole segment 114 gradually increases in the direction from the circumferential inner wall 112 of the frame 11 to the circumferential outer wall 111.

[0125] Therefore, when the card holder cap 71a is disposed within the first hole section 114, since the inclination directions of the first draft slope 712a and the second draft slope 116 are opposite, this causes the single-sided gap between the card holder cap 71a and the circumferential outer wall 111 of the frame 11 to gradually increase along the length direction from the circumferential inner wall 112 of the frame 11 to the circumferential outer wall 111 (this direction is parallel to the width direction of the electronic device). That is, in the length direction of the card holder cap 71a, the single-sided gap D1 between the position of the card holder cap 71a at the outer surface 711a and the circumferential outer wall 111 of the frame 11 reaches its maximum. Here, the single-sided gap D1 can also be understood as the distance between the two adjacent edges of the outer surface 711a and the circumferential outer wall 111 of the frame 11 in the length direction of the card holder cap 71a.

[0126] It should be noted that the outer surface 711a of the card tray cap 71a refers to the side of the card tray cap 71a that is away from the card tray body 72a. When the card tray cap 71a is provided in the first hole section 114, the outer surface 711a of the card tray cap 71a is flush with the circumferential outer wall 111 of the frame 11. Alternatively, when the card tray cap 71a is provided in the first hole section 114, the outer surface 711a of the card tray cap 71a may also have a small step difference from the circumferential outer wall 111 of the frame 11.

[0127] In addition, due to the arcuate surface design of the cassette cap 71a on the side near the circumferential outer wall 111 of the frame 11, and the arcuate surface design of the hole wall of the first hole segment 114 on the end near the circumferential outer wall 111 of the frame 11, the single-sided gap D1 between the position of the cassette cap 71a on the outer surface 711a and the circumferential outer wall 111 of the frame 11 is further increased along the length direction of the cassette cap 71a. This results in poor appearance refinement of the electronic device and affects the user experience. It should be noted that the arcuate surface is formed by rounded corners.

[0128] See you again Figure 9bCurrently, along the length of the card holder cap 71a, the single-sided gap D2 between the periphery of the card holder cap 71a at the position corresponding to the parting surface 240 of the mold 200 and the circumferential outer wall 111 of the frame 11 has been controlled to the tolerance limit (i.e., controlled to the minimum, approximately 0.05mm). At this time, the single-sided gap D1 is usually still 0.256mm. Due to the existence of the single-sided gap D1, the single-sided gap between the card holder cap 71a and the card insertion hole 113 in the length direction is relatively obvious.

[0129] Therefore, how to reduce the single-sided gap between the position of the card holder 71a on the outer surface 711a and the circumferential outer wall 111 of the frame 11 along the length direction of the card holder 71a without affecting the structure of the frame 11 has become a technical problem to be solved.

[0130] In view of this, the electronic device provided in this application has an optimized design of the card holder cap structure. Without affecting the frame structure, it can reduce the single-sided gap between the position of the card holder cap on the appearance surface and the circumferential outer wall of the frame along the length direction of the card holder cap, so as to improve the appearance refinement of the electronic device and enhance the user experience.

[0131] The structure of the card cap 71 provided in the embodiments of this application will be further described below with reference to the accompanying drawings and embodiments.

[0132] Figure 11 It shows Figure 8 Enlarged view at point B.

[0133] See Figure 11 The card tray 7 includes a card tray cap 71. The card tray cap 71 includes a first mating portion 713 and a second mating portion 714 that meet in the thickness direction. The projection of the first mating portion 713 onto the second mating portion 714 covers the second mating portion 714, such that the second mating portion 714 is obscured by the first mating portion 713 in the direction viewed from the circumferential outer wall 111 of the frame 11 towards the circumferential inner wall 112. To achieve the projection of the first mating portion 713 onto the second mating portion 714 covering the second mating portion 714, the maximum circumferential dimension of the first mating portion 713 should be greater than or equal to the maximum circumferential dimension of the second mating portion 714.

[0134] The first mating part 713 is located at one end of the first hole section 114 near the circumferential outer wall 111 of the frame 11, and the second mating part 714 is located at one end of the first hole section 114 near the circumferential inner wall 112 of the frame 11, so that the first mating part 713 is closer to the outer surface of the housing 1. The end face of the first mating part 713 facing away from the second mating part 714 forms the outer surface 711 of the card holder cap 71. At this time, while the card holder body 72 is installed on the mounting plate 12, a part of the card holder body 72 is located in the second hole section 115 and connects with the second mating part 714 to realize the installation of the card holder 7 on the housing 1.

[0135] The height of the first hole section 114 is H1. The height of the end faces of the first mating part 713 and the second mating part 714 within the first hole section 114 is H2. That is, the distance between the end faces of the first mating part 713 and the second mating part 714 and the bottom wall of the hole in the first hole section 114 is H2. H2 is greater than or equal to one-third of H1. For example, H2 can be greater than or equal to two-fifths of H1. Or, H2 can also be greater than or equal to one-half of H1, etc. Or, H2 can be greater than or equal to two-fifths of H1 and less than or equal to one-half of H1, etc.

[0136] It should be noted that when the card holder cap 71 is provided in the first hole section 114, the thickness direction of the card holder cap 71 is parallel to the hole height direction of the first hole section 114.

[0137] According to related technology, when the card holder cap 71a is disposed in the first hole section 114, the position of the peripheral side of the card holder cap 71a corresponding to the parting surface 240 is close to the second hole section 115 within the first hole section 114. The height of the position of the peripheral side of the card holder cap 71a corresponding to the parting surface 240 within the first hole section 114 is H0. H0 is approximately located at 1 / 6H1 to 1 / 8H1, so that the position of the peripheral side of the card holder cap 71a corresponding to the parting surface 240 within the first hole section 114 is close to the inner side of the first hole section 114.

[0138] Compared to related technologies (such as Figure 9a As shown in the figure, in this embodiment of the application, with the structure of the frame 11 and the thickness of the card holder cap 71 remaining unchanged, by setting H2 to be greater than or equal to one-third of H1, the position where the first mating part 713 and the second mating part 714 meet can be closer to the peripheral outer wall of the frame 11, that is, the position where the first mating part 713 and the second mating part 714 meet is moved outward within the first hole section 114.

[0139] It should be noted that the unchanged structure of the frame 11 includes the unchanged structure of the first hole segment 114 and the unchanged hole height H1.

[0140] Since the first hole segment 114 is an outwardly expanding structure that expands towards the circumferential outer wall 111 of the frame 11, when the single-sided gap D3 between the position where the first mating part 713 and the second mating part 714 meet and the circumferential outer wall 111 of the frame 11 is controlled to the tolerance limit along the length direction of the card cap 71, the single-sided gap D3 is the same as the single-sided gap D2.

[0141] If the position where the first mating part 713 and the second mating part 714 meet is closer to the side of the circumferential outer wall 111 of the frame 11 within the first hole section 114, the single-sided gap D1 between the position of the card holder cap 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 will be smaller.

[0142] Therefore, in this embodiment of the application, when the position where the first mating part 713 and the second mating part 714 meet is moved outward within the first hole section 114, the single-sided gap D1 between the position of the card holder cap 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be reduced, thereby improving the appearance refinement of the electronic device 100 and enhancing the user experience.

[0143] For example, with the dimensions of the first hole section 114 (including hole height H1, draft angle, etc.), the thickness of the card holder cap 71, and the curvature of the arc surfaces on the first hole section 114 and the card holder cap 71 remaining unchanged, experiments have verified that when the position where the first mating part 713 and the second mating part 714 meet is shifted inward or outward from the first hole section 114, compared to... Figure 9b The single-sided clearance D1 is 0.256mm, and the single-sided clearance D1 between the card cap 71 at the position of the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be reduced to at least 0.224mm. Among them, the dimensions of the first hole segment 114 include the hole height H1, draft angle, etc.

[0144] Therefore, it can be seen that by optimizing the structure of the card holder in this embodiment, the single-sided gap D1 between the card holder 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be significantly reduced, thereby improving the appearance and refinement of the electronic device 100.

[0145] Because the assembly of the card tray 7 on the electronic device 100 is affected by multiple components such as the housing 1, circuit board, and card holder, the assembly of the card tray 7 on the electronic device 100 is easily affected by many tolerances. These tolerances may include, but are not limited to, the machining tolerances of the housing 1, card holder, and card tray 7, as well as the assembly tolerances of the card tray 7 within the card insertion hole 113. This can easily cause user experience problems such as difficulty in inserting and removing the card tray or excessive tightness in the electronic device 100.

[0146] The projection of the first mating part 713 onto the second mating part 714 covers the second mating part 714. Therefore, the first mating part 713 serves as the effective mating section between the card holder cap 71 and the frame 11. Consequently, the greater the effective mating hole height between the card holder cap 71 and the frame 11, the larger the friction area between the card holder 7 and the frame 11 during insertion and removal. Due to the influence of manufacturing process tolerances, the risk of the card holder 7 getting stuck in the insertion hole 113 increases, making it easier for problems such as uneven insertion and removal or excessive tightness to occur.

[0147] Because the position where the first mating part 713 and the second mating part 714 meet is moved outward within the first hole section 114, the thickness of the first mating part 713 can also be reduced, thereby reducing the effective mating hole height between the card holder cap 71 and the frame 11. This reduces the friction area between the card holder 7 and the frame 11 during insertion and removal, thus solving the problem of the card holder cap 71 being difficult to insert or remove or too tight due to the influence of manufacturing process tolerances, and improving the user experience.

[0148] It should be noted that the manufacturing process tolerances include the machining tolerances of the housing 1, card holder and card tray 7 mentioned above, as well as the assembly tolerances of the card tray 7 in the card insertion hole 113.

[0149] In some embodiments, H2 can be greater than or equal to half of H1 and less than or equal to two-thirds of H1.

[0150] If H2 is greater than one-third of H1 and can be less than one-half of H1, then while ensuring that the card holder cap 71 can be processed and formed, the degree of outward movement of the position where the first mating part 713 and the second mating part 714 meet within the first hole section 114 can be further improved. Therefore, the single-sided gap D1 between the position of the card holder cap 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 has room for further reduction.

[0151] If H2 is greater than two-thirds of H1, then due to the influence of the above-mentioned manufacturing process tolerance, when the card holder cap 71 is placed in the card slot 113, part of the card holder cap 71 may protrude from the circumferential outer wall 111 of the frame 11, affecting the smoothness of the electronic device 100 on the peripheral surface.

[0152] Therefore, when H2 is greater than or equal to half of H1 and less than or equal to two-thirds of H1, H2 can be controlled within a suitable range. This further reduces the single-sided gap D1 between the position of the card holder 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 along the length direction of the card holder 71. At the same time, it also prevents the first mating part 713 from protruding from the circumferential outer wall 111 of the frame 11, which would affect the smoothness of the electronic device 100 on the peripheral surface and improve the user's feel.

[0153] The card holder cap 71 also includes a third mating portion 715. The third mating portion 715 is connected to the end of the second mating portion 714 away from the first mating portion 713. Furthermore, at least a portion of the third mating portion 715 is located within the second hole section 115. The card holder body 72 is mounted on the mounting plate and connected to the third mating portion 715 to realize the mounting of the card holder 7 on the housing 1.

[0154] See Figure 11When the card holder cap 71 is located within the first hole section 114, the end of the second mating part 714 facing away from the first mating part 713 can abut against the stepped surface of the stepped structure within the card insertion hole 113. Alternatively, when the card holder cap 71 is located within the first hole section 114, the end of the second mating part 714 facing away from the first mating part 713 can also have a gap with the stepped structure.

[0155] Figure 12 It shows Figure 11 A schematic diagram of the structure of the card tray 7, the frame 11, and the mold 200.

[0156] See Figure 12 In some embodiments, the card holder 71 can be configured to be injection molded by mold 200. The first mating portion 713 can be located within the slider 220, and the second mating portion 714 and the third mating portion 715 can be located within the mold core 210. The end faces of the first mating portion 713 and the second mating portion 714 that meet are coplanar with the parting surface 240 of the mold 200. That is, the end faces of the first mating portion 713 and the second mating portion 714 that meet are located on the same plane as the parting surface 240. In this case, the outward shift of the position where the first mating portion 713 and the second mating portion 714 meet within the first hole section 114 can be understood as the outward shift of the parting surface 240 within the first hole section 114.

[0157] By reducing the groove depth within the slider 220 of the mold 200, the first mating part 713 can occupy a smaller proportion in the thickness direction of the card holder cap 71 while maintaining the same thickness. Compared to the card holder cap 71a mentioned in related technologies, this allows the position where the first mating part 713 and the second mating part 714 meet to shift outward within the first hole section 114 when the card holder cap 71 is located within the first hole section 114. Furthermore, when the first mating part 713 occupies a smaller proportion in the thickness direction of the card holder cap 71, the draft height h of the slider 220 can also be reduced, facilitating the demolding of the card holder cap 71.

[0158] It should be understood that the groove depth of the slot in the slider 220 can be understood as the draft height h of the slider 220.

[0159] In other embodiments, the cap 71 can also be formed by machining. In this application, the forming process of the cap 71 is not further limited.

[0160] The following section uses the example of the cassette cap 71 being formed by injection molding through mold 200 to further illustrate the structure of the cassette cap 71.

[0161] Figure 13 It shows Figure 11 Enlarged view at point C.

[0162] See Figure 13In some embodiments, the wall of the first hole segment 114 is inclined away from the card holder cap 71, so that the first hole segment 114 forms an outwardly expanding structure that expands toward the circumferential outer wall 111 of the frame 11. The inclined wall of the first hole segment 114 forms a second draft slope 116. Thus, when the portion of the frame 11 with the insertion hole is injection molded by the mold 200, the second draft slope 116 facilitates the removal of the frame 11 from the mold 200.

[0163] The circumferential sidewall of the first mating part 713 may include a first inclined surface, the inclination direction of which is opposite to the inclination direction of the hole wall. The first inclined surface can be regarded as a first draft slope 712. In this way, when the card holder 7 is injection molded through the mold 200, the first draft slope 712 of the card holder cap 71 facilitates the card holder 7 to be pulled out from the mold 200.

[0164] Because the inclination direction of the first inclined surface is opposite to the inclination direction of the hole wall, the single-sided gap between the position of the card holder 7 on the outer surface 711 and the first hole segment 114 in the length direction of the card holder cap 71 gradually increases from the circumferential inner wall 112 to the circumferential outer wall 111 of the frame 11. In this embodiment, by shifting the position where the first mating part 713 and the second mating part 714 meet outward within the first hole segment 114, the single-sided gap D1 between the position of the card holder cap 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be reduced, thereby improving the appearance refinement of the electronic device 100 and enhancing the user experience.

[0165] It should be noted that when the wall of the first hole segment 114 is inclined away from the card holder cap 71, and the difficulty of pulling the card holder out of the mold 200 is not too high, or when the card holder 7 is machined, the circumferential sidewall of the first mating part 713 can also be a vertical surface, which can be perpendicular to the outer surface 711. In this way, without changing the structure of the frame 11 and the thickness of the card holder cap 71, the single-sided gap between the position of the card holder cap 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be reduced, thereby improving the appearance refinement of the electronic device 100.

[0166] The end face of the first mating part 713 facing the second mating part 714 is the contact surface. The second mating part 714 is in contact with the contact surface to achieve the connection between the second mating part 714 and the first mating part 713. One side of the circumferential sidewall of the first mating part 713 is in contact with the contact surface, and the other side is in arc-shaped contact with the outer surface 711.

[0167] Figure 14 for Figure 11 Dimensional diagram of the middle card holder 7.

[0168] See Figure 14The thickness of the first mating part 713 is H3, and the thickness of the second mating part 714 is H4. H4 is greater than or equal to H3.

[0169] Compared to related technologies, when H4 is greater than or equal to H3, the first mating part 713 occupies a larger proportion in the thickness direction of the card holder cap 71. Thus, when the card holder cap 71 is located in the first hole section 114, the second mating part 714 occupies more space in the hole height direction of the first hole section 114 compared to the first mating part 713, allowing the first mating part 713 to be closer to one side of the circumferential outer wall 111 of the frame 11 within the first hole section 114. With the structure of the frame 11 and the thickness of the card holder cap 71 remaining unchanged, the end faces where the first mating part 713 and the second mating part 714 meet are closer to the circumferential outer wall of the frame 11. This achieves an outward shift of the meeting position of the first mating part 713 and the second mating part 714 within the first hole section 114, thereby reducing the single-sided gap D1 between the position of the card holder cap 71 on the outer surface 711 and the circumferential outer wall 111 of the frame 11, improving the aesthetic refinement of the electronic device 100.

[0170] It should be noted that when the second mating part 714 abuts against the bottom wall of the first hole section 114, H4 is equal to H2.

[0171] In some embodiments, H3 is greater than 0.2 mm and less than or equal to 0.4 mm.

[0172] Since the minimum value of H3 is limited by the current processing capability of mold 200, it is difficult to manufacture a card holder 7 that meets the requirements (H3 less than 0.2mm) when H3 is less than 0.2mm, based on the current processing capability of mold 200.

[0173] When H3 is greater than 0.4mm, the effective mating hole height between the card holder cap 71 and the frame 11 is relatively large. Due to the influence of the manufacturing process tolerance, the card holder 7 is more likely to get stuck in the card insertion hole 113, which may easily lead to problems such as difficulty in insertion and removal or excessive tightness.

[0174] Furthermore, since the first hole segment 114 is configured as either an outward expansion structure or a first inclined surface on the first mating part 713, when H3 is greater than 0.4mm, the position where the first mating part 713 and the second mating part 714 meet is closer to the inner wall of the periphery of the frame 11. This results in a smaller outward displacement of the position where the first mating part 713 and the second mating part 714 meet within the first hole segment 114, thus limiting the improvement in the appearance refinement of the electronic device 100.

[0175] Therefore, by limiting H3 to greater than 0.2 mm and less than or equal to 0.4 mm, this embodiment of the application ensures that the current mold 200 has the capability to produce a compliant card holder 7. This not only reduces the risk of the card holder 7 getting stuck in the card insertion hole 113 and avoids problems such as the card holder 7 not being easy to insert or remove or being too tight, but also ensures that the position where the first mating part 713 and the second mating part 714 meet has a large outward displacement within the first hole segment 114. This effectively reduces the single-sided gap D1 between the position of the card holder on the outer surface 711 and the circumferential outer wall 111 of the frame 11, effectively improving the appearance and refinement of the electronic device 100.

[0176] For example, experimental verification shows that when H3 is greater than 0.2mm and less than or equal to 0.4mm, the single-sided gap D1 between the card holder cap 71 at the position of the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be reduced to at least 0.224mm. Therefore, it can be seen that by optimizing the structure of the card holder cap in this embodiment, the single-sided gap D1 between the card holder cap 71 at the position of the outer surface 711 and the circumferential outer wall 111 of the frame 11 can be significantly reduced, improving the aesthetic refinement of the electronic device 100.

[0177] Figure 15 This is a structural schematic diagram of an injection molded part 300 and a mold 200 provided in an embodiment of this application.

[0178] See Figure 15 When injection material is injected into mold 200 and forms injection molded part 300 within cavity 230 of mold 200, point A of mold core 210 and point B of slider 220 need to be aligned to ensure that the mold core 210 and slider 220 both form a plane facing the inside of cavity 230, and to ensure that mold core 210 and slider 220 are in contact. Since alignment of points A and B requires alignment in both the horizontal and vertical directions, this alignment is quite difficult. The horizontal direction can be referenced to direction W1, and the vertical direction to direction W2.

[0179] If points A and B are not aligned, the mold core 210 and the slider 220 will be misaligned on the parting surface 240, resulting in a gap between them. Alternatively, the mold core 210 and the slider 220 may be misaligned vertically. When the injection material is injected into the mold 200, it will run into the gap between the mold core 210 and the slider 220, or into the misaligned area. This will cause burrs 310 to form on the periphery of the molded part 300 at the corresponding parting surface 240. Since burrs 310 are ineffective parts of the molded part 300, their presence affects the yield of the molded part 300. Therefore, burrs 310 need to be manually removed.

[0180] When the card holder 71 is formed by injection molding, the card holder 71 is an injection molded part 300. If the end faces of the first mating part 713 are all connected to the second mating part 714, then the A point of the mold core 210 and the B point of the slider 220 also need to be aligned, which may produce a burr 310 in the circumferential direction of the card holder 7.

[0181] See you again Figure 13 In some embodiments, to prevent burrs 310 from forming on the circumferential surface of the cap 71, the second mating portion 714 is in contact with a portion of the end face of the first mating portion 713, and the portion of the end face of the first mating portion 713 not in contact with the second mating portion 714 can form an interface 7131. That is, the second mating portion 714 is in contact with a portion of the contacting surface, and the portion of the contacting surface not in contact with the second mating portion 714 can form an interface 7131.

[0182] By setting the interface 7131, when the card holder cap 71 is formed by injection molding, it is only necessary to have the mold core 210 and the slider 220 abut against each other at the parting surface 240 (i.e., at...). Figure 15 As shown in the diagram, the horizontal alignment (W1) is sufficient. The mold core 210 and slider 220 are slightly misaligned in the vertical direction, eliminating the need for vertical alignment and reducing the difficulty of aligning them. Thus, when the injection material for the card holder cap 71 is injected into the mold 200, it will move to the position where the mold core 210 and slider 220 are misaligned. The injection material at this position then serves as an effective structure of the first mating part 713 after molding, eliminating the need for manual removal after demolding the injection molded part 300. Therefore, this application, through the design of the interface 7131, can reduce the circumferential burr 310 of the card holder cap 71, improve the yield of the card holder cap 71, and reduce the manufacturing cost of the card holder 7.

[0183] See you again Figure 13 In some embodiments, the interface 7131 can be an annular structure surrounding the second mating portion 714, so that the interface 7131 is a closed annular structure. It should be understood that when the second mating portion 714 and the first mating portion 713 are in contact, and the circumferential dimension of the second mating portion 714 is smaller than the circumferential dimension of the first mating portion 713, and the second mating portion 714 is centered relative to the first mating portion 713 rather than being located at the edge, an annular interface 7131 can be formed on the end face of the first mating portion 713.

[0184] Alternatively, in other embodiments, when the second mating part 714 and the first mating part 713 are in contact, the circumferential dimension of the second mating part 714 is smaller than the circumferential dimension of the first mating part 713, and the second mating part 714 is provided on one side edge of the first mating part 713, the interface 7131 on the end face of the first mating part 713 can be a non-circular structure.

[0185] Compared to non-ring structures, when the interface 7131 is a closed ring structure, it can avoid the generation of burrs 310 at various circumferential positions of the card holder 71 formed during injection molding, thereby further improving the yield of the card holder 71 and reducing the manufacturing cost of the card holder 7.

[0186] The structure of the card cap 71 will be further explained below, taking the interface 7131 as an example of the above-mentioned annular structure.

[0187] See you again Figure 13 In some embodiments, the width of the interface 7131 is e, which can be greater than or equal to 0.03 mm. For example, the width of the interface 7131 is in the direction parallel to the length direction of the card holder cap 71.

[0188] If the width e of the interface 7131 is less than 0.03mm, the width e of the interface 7131 is too small, and the degree of misalignment between the mold core 210 and the slider 220 in the vertical direction is small. Although the interface 7131 is set, the circumferential direction of the card cap 71 may still produce a burr 310.

[0189] In this embodiment of the application, by limiting the value of the width e of the interface 7131, when the width e of the interface 7131 is greater than or equal to 0.03mm, the width e of the interface 7131 can be limited to a more suitable range, so as to ensure that the setting of the interface 7131 can effectively prevent the circumferential burr 310 from being generated by the card holder cap 71.

[0190] See you again Figure 13 In some embodiments, a clearance space 8 is provided between the second mating portion 714 and the hole wall of the first hole segment 114. The second mating portion 714 has a clearance portion 7141 on the side adjacent to the first mating portion 713. The clearance portion 7141 is used to increase the clearance space 8 in the length direction of the card holder cap 71.

[0191] Due to the outward expansion structure of the first hole segment 114, the diameter of the first hole segment 114 becomes smaller the closer it is to the circumferential inner wall 112 of the frame 11. This results in a smaller clearance space 8 between the first hole segment 114 and the second mating part 714 at the position closer to the circumferential inner wall 112 of the frame 11. Although clearance space 8 is provided, due to the machining tolerances of the first hole segment 114, the card holder 7, etc., or the assembly tolerances of the card holder 7 within the first hole segment 114, there is still a risk of the card holder 7 getting stuck during insertion and removal, affecting the smoothness of insertion and removal.

[0192] Therefore, by providing the avoidance part 7141, this embodiment can further increase the avoidance space 8 between the first hole segment 114 at the position of the circumferential inner wall 112 near the frame 11 and the second mating part 714, so as to further reduce the risk of jamming during the insertion and removal of the card holder 7 and further improve the smoothness of the insertion and removal of the card holder 7.

[0193] See you again Figure 13 In some embodiments, the second mating portion 714 has a second inclined surface on its circumferential sidewall, the second inclined surface having a first side and a second side. The first side is connected to the first mating portion 713, and the second side is inclined relative to the first side towards the center of the first hole segment 114. The second inclined surface forms a clearance portion 7141.

[0194] By tilting the second side, the circumferential dimension of the second mating part 714 can be gradually reduced in the direction from the first side to the second side, so as to increase the clearance space 8 between the first hole segment 114 at the position of the circumferential inner wall 112 near the frame 11 and the second mating part 714.

[0195] Figure 16 A schematic diagram of another type of cap 71 is shown.

[0196] See Figure 16 In some embodiments, when the end face of the second mating part 714 is in contact with the end face of the first mating part 713, the circumferential sidewall of the second mating part 714 can also be perpendicular to the end face of the first mating part 713, forming a clearance part 7141. This also increases the clearance space 8 between the first hole segment 114 near the circumferential inner wall 112 of the frame 11 and the second mating part 714. However, since the circumferential sidewall of the second mating part 714 is perpendicular to the end face of the first mating part 713, the stress on the card holder cap 71 may concentrate at the intersection of the circumferential sidewall of the second mating part 714 and the end face of the first mating part 713, affecting the service life of the card holder 7.

[0197] Compared to the fact that the circumferential sidewall of the second mating part 714 is perpendicular to the end face of the first mating part 713, the setting of the second inclined surface can reduce the stress concentration at the intersection of the circumferential sidewall of the second mating part 714 and the end face of the first mating part 713, thus ensuring that the card holder 7 has a longer service life.
