Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to a card holder and an electronic device. Background Art

[0002] The development of electronic devices has transformed our lifestyles, particularly tablets and mobile phones, which have brought significant convenience to our lives. Electronic devices often feature a card holder for installing electronic cards, enabling communication, storage, and other functions. The card holder includes a card tray, which holds the electronic card. The clamping mechanism within the card holder holds the card tray. Excessive clamping force can make insertion and removal difficult and can lead to significant material loss. Summary of the Invention

[0003] The present invention provides a card holder and electronic device. The present invention realizes miniaturization of the card holder by rationally designing the card holder structure, and avoids the problem of difficult insertion and removal of the card holder and serious material loss of the clamping mechanism due to excessive clamping force on the card holder.

[0004] In a first aspect, embodiments of the present application provide a card holder. The card holder is used in an electronic device that includes an electronic card. The card holder includes a housing, a card connector, a card tray, and a clamping mechanism. The card tray can be moved into and out of the housing. The card tray is provided with a card slot, wherein the short side of the card slot extends in the same direction as the insertion direction of the card tray. The electronic card is positioned in the card slot. The housing can be made of metal, such as iron, copper, or aluminum.

[0005] Understandably, the direction in which the short side of the card slot extends is the same as the insertion direction of the card tray, allowing the electronic card to be inserted horizontally into the card holder. Inserting the electronic card horizontally into the card holder helps reduce the size of the card holder in the insertion direction, facilitating overall miniaturization of the card holder, reducing the space occupied by the card holder in the electronic device, and reserving sufficient space for batteries and other components within the electronic device, thereby improving space utilization in the electronic device.

[0006] The card connector is located within the housing. The card connector includes an insulating member and a terminal. The terminal includes a fixed portion, at least two elastic arms, and a contact portion. The fixed portion is fixed to the insulating member, the contact portion is spaced apart from the fixed portion, and at least two elastic arms are fixedly connected between the fixed portion and the contact portion. The at least two elastic arms are arranged at an angle to the arrangement of the fixed portion and the contact portion. When the card tray is located within the housing, the contact portion is arranged corresponding to the card slot. The number of elastic arms can be two, three, four, or five, and multiple elastic arms can be arranged side by side on the same side of the contact portion. The terminal can be an integrally molded structure, which facilitates simplified manufacturing and increased structural strength. In other embodiments, the multiple structural components of the terminal can also be separate structures and assembled and fixed to form the terminal. The insulating member can be made of a material such as plastic and serves to insulate the multiple terminals from each other and from other structural components that do not require electrical connection. In embodiments of the present application, increasing the number of elastic arms can enhance the structural strength and stability of the terminal, facilitating a stable electrical connection between the terminal and the electronic card.

[0007] The clamping mechanism includes a first clamping member and a second clamping member arranged relative to each other along a first direction, wherein the first direction is arranged at an angle to the insertion direction. When the card holder is moved into the housing, the card holder is located between the first clamping member and the second clamping member. The first clamping member and the housing are separate structures, and the first clamping member is assembled and fixed to the housing. For example, the first clamping member can be assembled and fixed to the housing by welding or gluing. The first direction can be perpendicular to the insertion direction.

[0008] It is understandable that when the card holder can realize the horizontal insertion of the electronic card, the size of the shell in the insertion direction is small, which will cause the size of the first clamping member and the second clamping member in the insertion direction to be small. If the first clamping member is integrally formed with the shell, the size of the first clamping member will also be limited by some structures on the shell, and the size is difficult to increase. If the size of the first clamping member and the second clamping member in the insertion direction is too small, it will cause the clamping force of the first clamping member and the second clamping member on the card tray to be too large, making it difficult for the card tray to move into the shell or difficult for the card tray to move out of the shell. In addition, during the process of the card tray being moved out of or into the card holder, the first clamping member and the second clamping member will be deformed. If the size of the first clamping member and the second clamping member is too small, it will cause serious material loss of the first clamping member and the second clamping member during the process of the card tray being repeatedly moved out of or into the card holder, thereby reducing the service life of the first clamping member and the second clamping member.

[0009] In the embodiment of the present application, by configuring the first clamping member and the housing as a separate structure, the size of the first clamping member is not restricted by certain structures on the housing. The first clamping member can be configured to be longer in the insertion direction, thereby preventing the first clamping member from exerting excessive force on the card tray, making it difficult to move the card tray, and preventing excessive material loss in the first clamping member. By configuring the first clamping member and the housing as a separate structure, the embodiment of the present application allows for greater flexibility in the configuration of the size, thickness, material, etc. of the first clamping member.

[0010] In one possible embodiment, the first clamping member includes a mounting portion, a first connecting portion, a second connecting portion and a clamping portion, the mounting portion and the clamping portion are spaced apart, the mounting portion is fixedly connected to the shell, the clamping portion is used to clamp the card holder, the first connecting portion connects one end of the mounting portion and one end of the clamping portion, the second connecting portion connects the other end of the mounting portion and the other end of the clamping portion, and the spacing between the first connecting portion and the second connecting portion is greater than or equal to 4mm. For example, the spacing between the first connecting portion and the second connecting portion can be 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm or 8mm, etc., and can be set as needed. By setting the spacing between the first connecting portion and the second connecting portion to be greater than or equal to 4mm, the embodiment of the present application can ensure the size of the first clamping member in the insertion direction, avoid the size of the first clamping member in the insertion direction being too short, resulting in excessive holding force of the first clamping member on the card holder, and the card holder is difficult to move out of or into the shell. In addition, by setting the distance between the first connecting part and the second connecting part to be greater than or equal to 4 mm, it is helpful to avoid the first clamping part being too small, which may cause serious material loss of the first clamping part during repeated movement of the card tray in or out, thereby reducing the service life of the first clamping part.

[0011] In one possible embodiment, the mounting portion is bent toward one side of the clamping portion relative to the clamping portion. In the embodiment of the present application, by setting the mounting portion to be bent toward one side of the clamping portion relative to the clamping portion, the space occupied by the first clamping member in the thickness of the card holder can be reduced, which is conducive to the miniaturization of the card holder.

[0012] In a possible embodiment, the mounting portion is provided with a first positioning portion, and the shell is provided with a second positioning portion, and the first positioning portion and the second positioning portion cooperate with each other. By providing the first positioning portion and the second positioning portion to cooperate with each other, the first clamping member can be quickly and accurately fixed to the shell. The number of first positioning portions can be one or more, and the number of second positioning portions can also be one or more, and multiple can be understood as two or more. When the number of first positioning portions is multiple, the multiple first positioning portions are distributed at intervals. The multiple first positioning portions can be set to structures of different sizes or shapes to achieve positioning of the first clamping member and the shell, avoid positioning errors between the first clamping member and the shell, and facilitate direct and accurate positioning.

[0013] In one possible embodiment, the first positioning portion is a protrusion, and the second positioning portion is a groove or an opening, or the first positioning portion is a groove or an opening, and the second positioning portion is a protrusion, with the protrusion located within the groove or the opening. Providing the protrusion in conjunction with the groove or the opening facilitates quick and accurate securing of the first clamping member to the housing. It is understood that the protrusion may be a raised point, a protruding column, or a conical protrusion, etc.

[0014] In a possible embodiment, the cross section of the protrusion perpendicular to the protrusion direction is an asymmetric structure, such as a polygon with unequal side lengths, so that the first clamping member and the shell can only be connected at a fixed angle to avoid inaccurate positioning.

[0015] In one possible embodiment, the card holder includes a push rod, which is slidably connected to the shell, and the push rod is used to push the card tray out of the shell; when the card tray moves into the shell, the first clamping member and the push rod are located on the same side of the card tray, and the first clamping member is located on the side of the push rod facing the card tray. Since the first clamping member and the push rod are located on the same side of the card tray, if the first clamping member and the shell are integrally formed, the size of the first clamping member will also be limited by the structure on the shell for connecting the push rod, and the size is difficult to increase. In the embodiment of the present application, by setting the first clamping member and the shell as a split structure, the size setting of the first clamping member does not need to be limited by the structure on the shell for connecting the push rod, and the size of the first clamping member in the insertion direction can be set longer, thereby avoiding the first clamping member from having too much clamping force on the card tray, which makes it difficult to move the card tray, and avoiding excessive material loss of the first clamping member.

[0016] In one possible embodiment, the shell includes a folding portion, the push rod is located in a track formed by the folding portion, the folding portion includes a first end and a second end arranged opposite to each other along the insertion direction, and the first end and the second end are hollowed out; the surface of the first connecting portion facing the second connecting portion is flush with the surface of the first end facing the second end, or the surface of the second connecting portion facing the first connecting portion is flush with the surface of the second end facing the first end. It can be understood that the first clamping member and the shell are split structures, and the size setting of the first clamping member does not need to be restricted by the structure (folding portion) on the shell for connecting the push rod. The embodiment of the present application ensures that the size of the first clamping member in the insertion direction can be set larger by setting the surface of the first connecting portion facing the second connecting portion to be flush with the surface of the first end facing the second end, or the surface of the second connecting portion facing the first connecting portion to be flush with the surface of the second end facing the first end.

[0017] In one possible embodiment, the second clamping member and the shell are split structures, and the second clamping member is assembled and fixed to the shell. For example, the second clamping member can be assembled and fixed to the shell by welding or gluing. In the embodiment of the present application, the second clamping member and the shell are arranged as a split structure, so that the size, thickness, and material of the second clamping member are highly flexible. In other embodiments, the second clamping member and the shell can be an integrally formed structure, which does not require a fixed connection, which is conducive to simplifying the process and also helps to improve the structural strength and stability of the second clamping member and the shell.

[0018] In one possible embodiment, the contact point between the clamping portion of the second clamping member and the card tray is the second point, the contact point between the clamping portion of the first clamping member and the card tray is the first point, and the direction of the line connecting the first point and the second point is parallel to the long side of the card slot. In this embodiment of the application, by setting the direction of the line connecting the first point and the second point to be parallel to the long side of the card slot, this ensures that both sides of the card tray are subjected to uniform clamping force, thereby preventing uneven force on both sides of the card tray from causing instability of the card tray within the card holder.

[0019] In one possible embodiment, the size of the second clamping member in the insertion direction is the same as the size of the first clamping member in the insertion direction to ensure that both sides of the card tray are subjected to uniform clamping force, thereby avoiding uneven force on both sides of the card tray causing instability of the card tray in the card holder. The size of the second clamping member is not limited by the structure of the push rod connected to the shell, and the size setting flexibility is relatively high. In other embodiments, the size of the second clamping member in the insertion direction may also be different from the size of the first clamping member in the insertion direction, and this embodiment of the application does not limit this.

[0020] In one possible embodiment, the main body of the terminal includes at least two elastic arms and the contact portion. The main body protrudes relative to the surface of the fixed portion, and the outer edge of the main body is bent in a direction opposite to the protruding direction of the main body. This embodiment of the present application advantageously prevents the outer edge of the terminal from damaging the electronic card during insertion and removal of the electronic card by setting the outer edge of the main body to bend in a direction opposite to the protruding direction of the main body. It is understood that the surface of the main body facing the electronic card can be a smooth curved surface to prevent the terminal from damaging the electronic card.

[0021] In one possible embodiment, there are two card connectors, which are spaced relative to each other along a second direction to form a slot, the second direction being angled with the insertion direction and the first direction; there are two card slots, which are arranged along the second direction; when the card tray is located in the slot, the terminals of one of the card connectors are arranged corresponding to one of the card slots, and the terminals of the other card connector are arranged corresponding to the other card slot. In the embodiment of the present application, by setting the number of card connectors to two and the number of card slots to two, that is, the number of electronic cards to two, the two electronic cards are stacked in the second direction and inserted laterally, which helps to reduce the overall size of the card holder, avoid the card holder occupying too large an area within the electronic device, and improve the integration of the card holder.

[0022] In one possible embodiment, the first clamping member is assembled and fixed to the base plate of the housing, one of the card connectors is fixed to the base plate, and a portion of the insulating member is provided between the terminal of the card connector fixed to the base plate and the base plate. During the injection molding process of the insulating member, the terminal and the housing serve as inserts and are integrally formed with the insulating member. In the embodiment of the present application, the terminal of the card connector fixed to the housing and the housing are formed into an integral structural member through an insert injection molding process, which simplifies the assembly process of the insulating member, the terminal, and the housing, and increases the connection strength between the insulating member, the terminal, and the housing, thereby increasing the structural stability of the card holder. In addition, if the insulating member and the housing are of a split structure and are assembled and fixed by gluing or welding, there will be a gap between the insulating member and the housing, and dust or other impurities may enter the gap. In the embodiment of the present application, by setting the terminal of the card connector fixed to the housing, the insulating member, and the housing to be formed into an integral structural member through an insert injection molding process, there is no gap between the insulating member and the housing, thus avoiding foreign matter between the insulating member and the housing.

[0023] In one possible embodiment, the insulating member of the card connector fixed to the base plate is provided with a recess, and the first clamping member is provided with a convex portion, or the insulating member of the card connector fixed to the base plate is provided with a convex portion and the first clamping member is provided with a recess, and the convex portion is located inside the recess. It is understandable that during the insertion and removal of the card tray, the first clamping member will be subjected to the force of the card tray on the first clamping member along the insertion direction, so that after multiple insertions and removals of the card tray, the connection strength between the first clamping member and the shell may be reduced, resulting in the risk of the first clamping member being separated from the shell. In the embodiment of the present application, by arranging the convex portion to be located inside the recess, the insulating member can limit and support the first clamping member, thereby preventing the first clamping member from being separated from the shell after multiple insertions and removals of the card tray.

[0024] In one possible implementation, a portion of the first clamping member is located between the base plate and the insulating member of the card connector fixed to the base plate. This embodiment of the present application positions a portion of the first clamping member between the base plate and the insulating member of the card connector fixed to the base plate, thereby enabling the insulating member to restrain and support the first clamping member, thereby preventing the first clamping member from detaching from the housing after repeated insertion and removal of the card tray.

[0025] In one possible embodiment, the housing is provided with a bridge, the bridge comprising an embedded portion and a first end and a second end disposed opposite each other, the embedded portion being located between the first end and the second end; the first end and the second end are both fixed to the base plate, a gap is provided between the embedded portion and the base plate, and the embedded portion is embedded within the insulating member of the card connector fixed to the base plate. In this embodiment of the present application, by providing the embedded portion to be embedded within the insulating member of the card connector fixed to the base plate, the connection strength between the insulating member fixed to the housing and the housing is increased, thereby improving connection reliability.

[0026] In one possible embodiment, the base plate is provided with a reinforcement hole or reinforcement groove, and the insulating member of the card connector fixed to the base plate includes an insulating body and an extension portion, the insulating body being fixed to the surface of the base plate, and the extension portion being embedded in the reinforcement hole or reinforcement groove. In this embodiment of the present application, by providing the extension portion embedded in the inner wall of the reinforcement hole, a reliable connection between the insulating member and the housing is facilitated.

[0027] In one possible embodiment, the main body of the terminal includes at least two of the elastic arms and the contact portion, the shell includes a hollow area, and the main body is arranged corresponding to the hollow area. One of the card connectors is fixed to the bottom plate of the shell. The corresponding arrangement of the main body of the terminal and the hollow area can be understood as the projection of the main body of the terminal on the plane where the bottom plate of the shell is located is located in the hollow area. During the insertion of the card tray into the shell, the card tray will exert a force on the terminal in the direction of the bottom plate, the main body of the terminal will be deformed and close to the bottom plate, and the contact between the main body of the terminal and the metal shell will cause a short circuit. In the embodiment of the present application, by providing a hollow area, the terminal will not contact the shell when it is subjected to a force in the direction of the bottom plate, thereby avoiding the contact between the terminal and the shell when the card tray is inserted, causing a short circuit. In addition, by providing a hollow area, the weight of the shell can be reduced, which is conducive to the lightweight design of the card holder.

[0028] In a second aspect, the present application provides an electronic device comprising a circuit board and a card holder as described in any of the aforementioned embodiments, wherein the card holder is fixed to the circuit board, the card slot is used to install the electronic card, and the terminal electrically connects the electronic card and the circuit board. The electronic device can be a mobile phone or a tablet computer, and the electronic device can be a straight-screen device or a folding device, where a straight-screen device can be understood as a device that does not fold. The electronic card can be a data card, a subscriber identity module (SIM), or a nano memory card (NM), etc., and this embodiment of the present application does not limit this.

[0029] In one possible embodiment, the electronic device includes a housing, the circuit board and the card holder are both located within the housing, and an opening is provided on a short side of the housing, the opening being used for the card holder to extend out of the housing. In other embodiments, the opening on the housing for removing the electronic card from the electronic device or inserting the electronic card into the electronic device may also be provided on a long side of the housing. This embodiment of the present application is not limited to this, and may be provided as needed.

[0030] The card holder of the embodiment of the present application can realize the horizontal insertion of the electronic card, which is beneficial to reducing the size of the card holder in the insertion direction and facilitating the miniaturization of the card holder as a whole. The number of elastic arms in the embodiment of the present application is at least two, which can increase the structural stability of the terminal. The embodiment of the present application sets the first clamping member and the shell as a split structure, and the size setting of the first clamping member is highly flexible. The size of the first clamping member in the insertion direction can be set longer, avoiding the first clamping member from having an excessively large clamping force on the card tray, which makes the card tray difficult to move, and avoiding excessive material loss of the first clamping member.

The size and shape of the electronic device 100, as well as the size, shape, and installation position of the camera module 20, battery 30, circuit board 40, card holder 50, and electronic card 60, can be set as needed. The specific structure of the electronic device 100 is not limited in this embodiment of the application.

[0062] like Figure 2 、 Figure 3 and Figure 4 As shown, Figure 2 for Figure 1 The schematic diagram of the structure of the card holder 50 and the electronic card 60 is shown in FIG. Figure 3 for Figure 2 The schematic structural diagram of the card holder 50 and the electronic card 60 from another angle is shown.

The card tray 53 can be moved into or out of the housing 51 through the opening side 515.

[0064] In some embodiments, the length of the first side portion 511 and the length of the third side portion 513 can be the same, and the length of the first side portion 511 and the length of the third side portion 513 can both be less than the length of the second side portion 512. It is understandable that the lengths of the first side portion 511, the second side portion 512, and the third side portion 513 can be designed as needed, and the embodiment of the present application does not limit the lengths of the first side portion 511, the second side portion 512, and the third side portion 513.

[0065] The housing 51 can be made of metal, such as iron, copper, or aluminum. The housing 51 can provide a shielding function, shielding the electronic card 60 from external signals and preventing the electronic card 60 signals from interfering with other signals in the electronic device 100. The housing 51 can also enhance the overall structural strength of the card holder 50.

[0066] The card connector 52 is located within the housing 51 and can be spaced apart from the bottom plate 514 of the housing 51. A first slot 517 is formed between the card connector 52 and the bottom plate 514 of the housing 51. The first slot 517 is used to accommodate the card tray 53. In other words, the card tray 53 can be located within the first slot 517. It is understandable that the first slot 517 can be part of the accommodating cavity 516.

[0067] The card connector 52 may include an insulating member 521 and terminals 522 that are fixedly connected. The insulating member 521 may be made of plastic or other materials. The insulating member 521 may function to connect the plurality of terminals 522 ( Figure 3 The function of insulating the terminals 522 from each other (taking the number of terminals 522 as an example, which is six), and the function of insulating the terminals 522 from other structural parts that do not require electrical connection, such as the insulating member 521 can insulate the terminals 522 from the metal shell 51.

[0068] See Figure 5 and Figure 6 , Figure 5 for Figure 4 The schematic structural diagram of the terminal 522 is shown in FIG. Figure 6 for Figure 4 The schematic diagram of the structure of the card connector 52 is shown. It should be noted that, Figure 5 Terminal 522 and Figure 6 The viewing angle of terminal 522 is different. Figure 5 The terminal 522 in FIG. 5 is a perspective of the terminal 522 facing the electronic card 60. Figure 6The terminal 522 in the figure is viewed from the side of the terminal 522 facing away from the electronic card 60. The terminal 522 may include a fixed portion 523, at least two elastic arms 524, and a contact portion 525. The fixed portion 523 is fixed to the insulating member 521, and the contact portion 525 is spaced apart from the fixed portion 523, such that a gap exists between them, or other structures may be provided between them. The at least two elastic arms 524 are located on the same side of the contact portion 525 and spaced apart, each elastic arm 524 being fixedly connected between the fixed portion 523 and the contact portion 525. The contact portion 525 is elastically protruding from the surface of the insulating member 521. It will be understood that when the card tray 53 is located within the housing 51, the contact portion 525 is positioned corresponding to the card slot 531 and is used to contact and electrically connect the electronic card 60 in the card slot 531. The corresponding arrangement of the contact portion 525 and the card slot 531 can be understood as when the card tray 53 is located in the shell 51 , the projection of the contact portion 525 on the plane where the card tray 53 is located is located in the card slot 531 .

[0069] It is understood that the number of elastic arms 524 can be two, three, four, or five, and the plurality of elastic arms 524 can be arranged side by side on the same side of the contact portion 525. Increasing the number of elastic arms 524 in this embodiment of the present application can enhance the structural strength and stability of the terminal 522, thereby facilitating a stable electrical connection between the terminal 522 and the electronic card 60.

[0070] In some embodiments, the arrangement direction of the at least two elastic arms 524 is arranged at an angle to the arrangement direction of the fixing portion 523 and the contact portion 525, which is conducive to achieving a miniaturized design of the terminal 522 as a whole, preventing the terminal 522 from occupying too much space in the card holder 50, and facilitating the miniaturization of the card holder 50. For example, the arrangement direction of the at least two elastic arms 524 can be perpendicular to the arrangement direction of the fixing portion 523 and the contact portion 525.

[0071] In some embodiments, the fixing portion 523 , at least two elastic arms 524 and the contact portion 525 may be triangular in shape as a whole. The triangular terminal 522 has high structural stability, which is beneficial to improving the reliability of the electrical connection between the terminal 522 and the electronic card 60 .

[0072] See Figure 1 、 Figure 5 and Figure 6, the terminal 522 may further include a welding portion 526, one end of the welding portion 526 is fixed to the fixing portion 523, and the other end of the welding portion 526 may be welded to the circuit board 40. When the card holder 50 is installed to the circuit board 40, the card connector 52 is located between the housing 51 and the circuit board 40, and the welding portion 526 is welded to the circuit board 40, thereby achieving a fixed connection and electrical connection between the card connector 52 and the circuit board 40. It is understandable that the welding portion 526 may be located between two adjacent elastic arms 524, making full and reasonable use of the structural space of the terminal 522, which is conducive to miniaturization of the terminal 522. It is understandable that the terminal 522 may be an integrally formed structure, which is conducive to simplifying the manufacturing process and having high structural strength. In other embodiments, the multiple structural components of the terminal 522 may also be a split structure and assembled and fixed to form the terminal 522.

[0073] See Figure 3 、 Figure 5 and Figure 6 The main body 527 of the terminal 522 includes at least two elastic arms 524 and a contact portion 525. The main body 527 protrudes from the surface of the fixed portion 523. The main body 527 includes an outer edge 5271 and an inner edge 5272. The outer edge 5271 bends relative to the inner edge 5272 in a direction opposite to the protrusion direction of the main body 527. In this embodiment of the present application, by bending the outer edge 5271 relative to the inner edge 5272 in a direction opposite to the protrusion direction of the main body 527, the outer edge 5271 of the terminal 522 is prevented from damaging the electronic card 60 during insertion and removal of the electronic card 60. It is understood that in some embodiments, the surface of the main body 527 facing the electronic card 60 can be a smooth curved surface to prevent the terminal 522 from damaging the electronic card 60.

[0074] See Figures 2 to 4 The card tray 53 can be located in the first slot 517 or moved out of the first slot 517. The card tray 53 is provided with a card slot 531, and the electronic card 60 can be installed in the card slot 531. The electronic card 60 can be roughly rectangular and include a long side 61 and a short side 62. The extension direction of the short side 5311 of the card slot 531 is the same as the insertion direction A3 of the card tray 53, so that the extension direction of the short side 62 of the electronic card 60 is the same as the insertion direction A3 of the card tray 53, and the electronic card 60 can be inserted horizontally into the card holder 50. The electronic card 60 can be inserted horizontally into the card holder 50, which can be understood as that during the process of inserting the electronic card 60 into the card holder 50, the extension direction of the short side 62 of the electronic card 60 is the same as the insertion direction A3 of the card tray 53. Inserting the electronic card 60 horizontally into the card holder 50 is beneficial to reducing the size of the card holder 50 in the insertion direction A3, which is beneficial to the overall miniaturization of the card holder 50, reducing the space occupied by the card holder 50 in the electronic device 100, reserving sufficient space for the arrangement of the battery 30, etc., and improving the space utilization of the electronic device 100.

[0075] See Figures 2 to 4 The clamping mechanism 55 includes a first clamping member 551 and a second clamping member 552 that are arranged relative to each other along a first direction A1. The first direction A1 is arranged at an angle to the insertion direction A3. For example, the first direction A1 can be perpendicular to the insertion direction A3. When the card tray 53 is located in the shell 51, the card tray 53 is located between the first clamping member 551 and the second clamping member 552. The first clamping member 551 and the second clamping member 552 are used to clamp the card tray 53. When the card tray 53 moves out of the card holder 50, it is necessary to overcome the clamping force of the first clamping member 551 and the second clamping member 552 on the card tray 53. When the card holder 53 moves into the card holder 50, the first clamping member 551 and the second clamping member 552 generate a clamping force on the card tray 53 until the card tray 53 moves to a preset position in the card holder 50. The first clamping member 551 and the second clamping member 552 stably set the card tray 53 in the card holder 50.

[0076] The first clamping member 551 and the housing 51 may be of a separate structure, and the first clamping member 551 is assembled and fixed to the housing 51. For example, the first clamping member 551 may be fixed to the housing 51 by welding or gluing.

[0077] In some embodiments, the size of the second clamping member 552 in the insertion direction A3 can be the same as the size of the first clamping member 551 in the insertion direction A3 to ensure that both sides of the card tray 53 are subjected to uniform clamping force, thereby avoiding uneven force on both sides of the card tray 53, which may cause the card tray 53 to be unstable in the card holder 50. The size of the second clamping member 552 is not limited by the structure of the push rod 54 connected to the shell 51, and the size setting flexibility is relatively high. In other embodiments, the size of the second clamping member 552 in the insertion direction A3 can also be different from the size of the first clamping member 551 in the insertion direction A3, and this embodiment of the application is not limited to this.

[0078] It is understandable that the card holder 50 can achieve that when the electronic card 60 is inserted horizontally, the size of the shell 51 in the insertion direction A3 is smaller, that is, the size of the first side portion 511 and the third side portion 513 in the insertion direction A3 is smaller (it is understandable that the size of the first side portion 511 and the third side portion 513 in the insertion direction A3 is smaller than the size of the second side portion 512 in the first direction A1), which will cause the size of the first clamping member 551 and the second clamping member 552 in the insertion direction A3 to be smaller. If the first clamping member 551 is integrally formed with the shell 51, the size of the first clamping member 551 will be affected by the structure of the shell 51 for connecting the push rod 54 (see Figure 7 and Figure 8The first clamping member 551 and the second clamping member 552 are limited by the folding portion 518 shown in the figure, and the size is difficult to be increased. If the size of the first clamping member 551 and the second clamping member 552 in the insertion direction A3 is too small, the clamping force of the first clamping member 551 and the second clamping member 552 on the card tray 53 will be too large, making it difficult to push the card tray 53 into the shell 51 or the card tray 53 is difficult to move out of the shell 51. In addition, during the process of moving the card tray 53 out of or into the card holder 50, the first clamping member 551 and the second clamping member 552 will be deformed. If the size of the first clamping member 551 and the second clamping member 552 is too small, the material of the first clamping member 551 and the second clamping member 552 will be seriously lost during the process of repeatedly moving the card tray 53 out of or into the card holder, thereby reducing the service life of the first clamping member 551 and the second clamping member 552.

[0079] See Figure 7 and Figure 8 , Figure 7 for Figure 4 The schematic structural diagram of a portion of the structure of the card holder 50 is shown. Figure 8 for Figure 7 The schematic diagram of the structure of the card holder is shown from another angle. The housing 51 is provided with a folded portion 518, which may be part of the third side portion 513. The folded portion 518 is used to form a track 5183 for the push rod 54 to slide. In other words, the push rod 54 can slide along the insertion direction A3 within the space of the folded portion 518. The folded portion 518 can limit the push rod 54 in the first direction A1, preventing it from moving in the first direction A1, thereby improving the structural stability of the card holder 50.

[0080] In some embodiments, the folding portion 518 may include a first end 5181 and a second end 5182 arranged along the insertion direction A3, the first end 5181 and the second end 5182 are spaced apart, and the space between the first end 5181 and the second end 5182 is hollow. If the first clamping member 551 is integrally formed with the shell 51, the two ends of the first clamping member 551 are limited by the space between the first end 5181 and the second end 5182, and the size of the first clamping member 551 in the insertion direction A3 is difficult to increase and is usually small. In the embodiment of the present application, the first clamping member 551 and the shell 51 are a split structure, and the size of the first clamping member 551 is not limited by the folding portion 518. The size setting of the first clamping member 551 in the insertion direction A3 is highly flexible and can be set as needed. In other embodiments, the space between the first end 5181 and the second end 5182 may also not be hollow, and the first end 5181 and the second end 5182 are connected as one body.

[0081] In the embodiment of the present application, the first clamping member 551 and the housing 51 are separated. The size of the first clamping member 551 is not restricted by the structure of the housing 51 for connecting the push rod 54. The size, thickness, material, and position of the first clamping member 551 are highly flexible. The first clamping member 551 can be set longer in the insertion direction A3, avoiding the first clamping member 551 being too small, which would result in the first clamping member 551 exerting excessive force on the card tray 53, making it difficult to move the card tray 53, and avoiding excessive material loss in the first clamping member 551. The card holder 50 of the embodiment of the present application allows the electronic card 60 to be inserted horizontally, which helps reduce the size of the card holder 50 in the insertion direction A3, facilitates the overall miniaturization of the card holder 50, and improves the space utilization of the electronic device 100. In this embodiment of the present application, by arranging at least two elastic arms 524 at an angle to the arrangement of the fixing portion 523 and the contact portion 525, a miniaturized design of the terminal 522 is achieved, preventing the terminal 522 from occupying excessive space in the card holder 50, thereby facilitating the miniaturization of the card holder 50. The presence of at least two elastic arms 524 in this embodiment of the present application increases the structural stability of the terminal 522 and facilitates improving the reliability of the electrical connection between the terminal 522 and the electronic card 60.

[0082] See Figure 4 In this embodiment of the present application, an electronic card 60 having six chip pins 63 is used as an example. The number of terminals 522 is six, with each terminal 522 electrically connected to a chip pin 63. In other embodiments, the number of chip pins 63 on the electronic card 60 may also be four, eight, or nine, etc., and this embodiment of the present application is not limited thereto. It is understood that the number of terminals 522 can be adjusted based on the number of chip pins 63 on the electronic card 60, and the number of terminals 522 and the number of chip pins 63 can be consistent.

[0083] See Figure 3 and Figure 7 The card holder 50 may include a detection mechanism 57, which is used to detect whether the card tray 53 is inserted. Exemplarily, the detection mechanism 57 may include an elastic member 571 and a matching member 572, the elastic member 571 includes a first end 573 and a second end 574, and the matching member 572 includes a third end 575 and a fourth end 576. During the process of inserting the card tray 53 into the shell 51, the card tray 53 compresses the elastic member 571, and the first end 573 is separated from the third end 575. By detecting that the electrical signal between the second end 574 and the fourth end 576 is open, it is determined that the card tray 53 is inserted. During the process of removing the card tray 53 from the shell 51, the elastic member 571 recovers its deformation, and the first end 573 contacts the third end 575. By detecting that the electrical signal between the second end 574 and the fourth end 576 is short, it is determined that the card tray 53 is removed.

[0084] See Figures 2 to 4, the card holder 50 may include a push rod 54, which may be slidably connected to the shell 51, and the push rod 54 is used to push the card tray 53 out of the shell 51. It can be understood that the push rod 54 can move back and forth along the insertion direction A3. When the card tray 53 is located in the shell 51, the first clamping member 551 and the push rod 54 are located on the same side of the card tray 53, and the first clamping member 551 is located on the side of the push rod 54 facing the card tray 53. Since the first clamping member 551 and the push rod 54 are located on the same side of the card tray 53, if the first clamping member 551 is integrally formed with the shell 51, the size of the first clamping member 551 will also be limited by the structure on the shell 51 for connecting the push rod 54, and the size is difficult to be increased. In the embodiment of the present application, the first clamping member 551 and the shell 51 are arranged as a split structure. The size setting of the first clamping member 551 does not need to be restricted by the structure on the shell 51 for connecting the push rod 54. The size of the first clamping member 551 in the insertion direction A3 can be set to be longer, so as to avoid the first clamping member 551 from exerting too much clamping force on the card tray 53, making the card tray 53 difficult to move, and avoiding excessive material loss of the first clamping member 551.

[0085] Illustratively, the card holder 50 may include a lever 561 and a rotation shaft 562. The rotation shaft 562 is fixed to the bottom plate 514 of the housing 51, and the lever 561 is rotatably connected to the rotation shaft 562. When the push rod 54 moves along the insertion direction A3 and approaches the second side portion 512, the push rod 54 acts on one end of the lever 561, pushing the lever 561 to rotate along the rotation shaft 562. The other end of the lever 561 acts on the card tray 53, removing the card tray 53 from the housing 51. When the card tray 53 is inserted into the housing 51, the card tray 53 acts on one end of the lever 561, causing the lever 561 to rotate along the rotation shaft 562. The other end of the lever 561 pushes the push rod 54 in a direction away from the second side portion 512.

[0086] It is understandable that the second clamping member 552 and the housing 51 can be integrally formed, eliminating the need for a fixed connection. This simplifies the process and improves the structural strength and stability of the second clamping member 552 and the housing 51. In other embodiments, the second clamping member 552 and the housing 51 can also be separate structures and secured to the housing 51 by welding or gluing. By configuring the second clamping member 552 and the housing 51 as separate structures, the embodiment of the present application allows for greater flexibility in the size, thickness, and material of the second clamping member 552.

[0087] See Figure 4 、 Figure 7 and Figure 9 , Figure 9 for Figure 7The first clamping member 551 is shown as a schematic structural diagram. The first clamping member 551 may include a mounting portion 5511, a first connecting portion 5512, a second connecting portion 5513, and a clamping portion 5514. The mounting portion 5511 and the clamping portion 5514 are spaced apart. The mounting portion 5511 is assembled and fixed to the bottom plate 514 of the housing 51, and the clamping portion 5514 is used to clamp the card tray 53. It can be understood that when the card tray 53 is located in the first slot 517, the mounting portion 5511 is located between the card tray 53 and the bottom plate 514, and the clamping portion 5514 is located on the side of the card tray 53. The first connecting portion 5512 connects one end of the mounting portion 5511 and one end of the clamping portion 5514, and the second connecting portion 5513 connects the other end of the mounting portion 5511 and the other end of the clamping portion 5514.

[0088] In some embodiments, the spacing L between the first connection portion 5512 and the second connection portion 5513 is greater than or equal to 4 mm. By setting the spacing L between the first connection portion 5512 and the second connection portion 5513 to be greater than or equal to 4 mm, the embodiment of the present application can ensure the size of the first clamping member 551 in the insertion direction A3, thereby preventing the first clamping member 551 from being too short in the insertion direction A3, resulting in the first clamping member 551 having an excessively large clamping force on the card tray 53, making it difficult for the card tray 53 to be moved out of or into the first slot 517. In addition, by setting the spacing L between the first connection portion 5512 and the second connection portion 5513 to be greater than or equal to 4 mm, it is helpful to avoid the first clamping member 551 from being too small, resulting in serious material loss of the first clamping member 551 during the repeated removal or insertion of the card tray 53, thereby reducing the service life of the first clamping member 551. Exemplarily, the distance L between the first connection portion 5512 and the second connection portion 5513 can be 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm or 8 mm, etc., and can be set according to specific needs.

[0089] In some embodiments, the mounting portion 5511 is bent toward one side of the clamping portion 5514 relative to the clamping portion 5514 , which helps to reduce the space occupied by the first clamping member 551 in the thickness of the card holder 50 and helps to miniaturize the card holder 50 .

[0090] It can be understood that in some embodiments, a groove can be provided on the base plate 514, and the mounting portion 5511 is fixed to the groove on the base plate 514, which can avoid the imbalance of the two sides of the card tray 53 caused by the mounting portion 5511 of the first clamping member 551 protruding from the surface of the base plate 514.

[0091] See Figure 4 and Figure 9In some embodiments, the clamping portion 5514 may include a first elastic arm 5515, an elastic section 5516, and a second elastic arm 5517, which are connected in sequence. The elastic section 5516 protrudes from the surfaces of the first elastic arm 5515 and the second elastic arm 5517. The elastic section 5516 may contact the card tray 53. When the card tray 53 moves into or out of the first slot 517, the elastic section 5516 contacts and squeezes the card tray 53, causing the first elastic arm 5515 and the second elastic arm 5517 to deform, and the first clamping member 551 generates a clamping force on the card tray 53.

[0092] See Figure 8 and Figure 9 In some embodiments, when the space between the first end portion 5181 and the second end portion 5182 is hollowed out, the surface of the first connecting portion 5512 facing the second connecting portion 5513 may be flush with the surface of the first end portion 5181 facing the second end portion 5182, or the surface of the second connecting portion 5513 facing the first connecting portion 5512 may be flush with the surface of the second end portion 5182 facing the first end portion 5181, or the surface of the first connecting portion 5512 facing the second connecting portion 5513 may be flush with the surface of the first end portion 5181 facing the second end portion 5182 and the surface of the second connecting portion 5513 facing the first connecting portion 5512 may be flush with the surface of the second end portion 5182 facing the first end portion 5181. It can be understood that the first clamping member 551 and the housing 51 are separate structures, and the size setting of the first clamping member 551 does not need to be limited by the structure (folded portion 518) on the housing 51 for connecting the push rod. In the embodiment of the present application, the surface of the first connecting part 5512 facing the second connecting part 5513 can be flush with the surface of the first end 5181 facing the second end 5182, or the surface of the second connecting part 5513 facing the first connecting part 5512 can be flush with the surface of the second end 5182 facing the first end 5181, which is beneficial to ensure that the size of the first clamping member 551 in the insertion direction A3 can be set larger.

[0093] See Figure 4 、 Figure 7 and Figure 9, the contact part between the clamping portion 5521 of the second clamping member 552 and the card tray 53 is the second part 5522. The contact part between the clamping portion 5514 of the first clamping member 551 and the card tray 53 is the first part 5510, and the first part 5510 is located in the elastic connection section 5516. The direction of the line connecting the first part 5510 and the second part 5522 is parallel to the long side direction of the card slot 531. It can be understood that the first part 5510 and the second part 5522 can be symmetrically distributed on opposite sides of the card tray 53 with respect to the card tray 53. In the embodiment of the present application, by setting the direction of the line connecting the first part 5510 and the second part 5522 to be parallel to the long side direction of the card slot 531, it is ensured that both sides of the card tray 53 are subjected to uniform clamping force, thereby avoiding uneven force on both sides of the card tray 53, which causes the card tray 53 to be unstable in the card tray 50.

[0094] See Figure 10 , Figure 10 for Figure 7 The schematic diagram of the exploded structure of the holder 50 is shown. The mounting portion 5511 of the first clamping member 551 is provided with a first positioning portion 5518, and the housing 51 is provided with a second positioning portion 519. The first positioning portion 5518 and the second positioning portion 519 cooperate to achieve positioning of the first clamping member 551 and the housing 51, facilitating quick and accurate fixing of the first clamping member 551 to the housing 51.

[0095] In some embodiments, the number of the first positioning portions 5518 can be one or more, and the number of the second positioning portions 519 can also be one or more, where "one or more" can be understood as two or more. Figure 10 For example, if there is one first positioning portion 5518 and one second positioning portion 519, when there are multiple first positioning portions 5518, the multiple first positioning portions 5518 are spaced apart. The multiple first positioning portions 5518 can be configured to have different sizes or shapes to achieve positioning between the first clamping member 551 and the housing 51, avoiding positioning errors between the first clamping member 551 and the housing 51 and facilitating direct and accurate positioning.

[0096] See Figure 10 In some embodiments, the first positioning portion 5518 may be a protrusion, and the second positioning portion 519 may be an opening. The protrusion is located within the opening to achieve positioning of the first clamping member 551 and the housing 51, facilitating quick and accurate fixation of the first clamping member 551 to the housing 51. It is understood that the protrusion may be a raised point, a raised column, or a conical protrusion. It is also understood that the second positioning portion 519 may also be a groove.

[0097] In other embodiments, the first positioning portion 5518 may be an opening, and the second positioning portion 519 may be a protrusion. The protrusion is located within the opening to achieve positioning of the first clamping member 551 and the housing 51, facilitating quick and accurate fixation of the first clamping member 551 to the housing 51. It is understood that the protrusion may be a raised point, a raised column, or a conical protrusion. It is also understood that the first positioning portion 5518 may also be a groove.

[0098] In some embodiments, the cross section of the protrusion perpendicular to the protrusion direction is an asymmetric structure, such as a polygon with unequal side lengths, so that the first clamping member 551 and the shell 51 can only be connected at a fixed angle to avoid inaccurate positioning.

[0099] Combine Figure 2 and Figure 3 The embodiment shown, see Figure 11 、 Figure 12 and Figure 13 , Figure 11 This is a structural diagram of another card holder 50 and electronic card 60. Figure 12 for Figure 11 The schematic structural diagram of the card holder 50 and the electronic card 60 from another angle is shown. Figure 13 for Figure 12 The exploded structure diagram of the card holder 50 and the electronic card 60 is shown.

[0100] In the embodiment of the present application, there can be two card connectors 52. The two card connectors 52 are spaced relative to each other along the second direction A2 and form a slot 501. To distinguish it from the aforementioned first slot 517, the slot 501 between the two card connectors 52 is referred to as the second slot 501. The second direction A2 can be arranged at an angle to the insertion direction A3 and at an angle to the first direction A1. For example, the second direction A2 is perpendicular to the insertion direction A3 and perpendicular to the first direction A1.

[0101] One of the card connectors 52 is fixed to the bottom plate 514 of the housing 51, and the other card connector 52 is spaced apart from the bottom plate 514 of the housing 51. For example, the insulating member 521 of one of the card connectors 52 is fixed to the bottom plate 514 of the housing 51. The terminals of both card connectors 52 protrude toward the inside of the second slot 501.

[0102] See Figure 13 The insulating member 521 fixed to the bottom plate 514 includes a surface 5215, a side surface 5216, and a guide surface 5217. The guide surface 5217 is connected between the side surface 5216 and the surface 5215. The guide surface 5217 is used for inserting the card tray 53 and guides the insertion of the card tray 53, facilitating quick and accurate insertion of the card tray 53. The guide surface 5217 can be a flat surface or a curved surface, which is not limited in this embodiment of the application.

[0103] See Figure 14 and Figure 15 , Figure 14 for Figure 12 The schematic diagram of the partial structure of the card holder 50 shown in FIG. Figure 15 for Figure 14 A cross-sectional view of a portion of the card holder 50 is shown at XX. The housing 51 can be made of metal, which provides both shielding and electrical conductivity. A portion of the insulating member 521 is provided between the terminals 522 of the card connector 52, which is fixed to the base plate 514.

[0104] In some embodiments, during the process of injection molding the insulating member 521, the terminal 522 and the housing 51 serve as inserts and are integrally molded with the insulating member 521. It is understandable that the terminal 522 of the card connector 52 fixed to the housing 51, the insulating member 521, and the housing 51 are molded into an integral structural member through an insert injection molding process. For example, the housing 51 can be integrally molded through an injection molding process, with the first clamping member 551 fixed to the housing 51. The terminal 522 can also be integrally molded through an injection molding process, with the completed housing 51 and terminal 522 placed in a mold as inserts, and plastic melted at high temperature into a liquid is injected into the mold. After the plastic cools, the insulating member 521 is formed. It is understandable that during the process of forming the insulating member 521 after the plastic cools, the insulating member 521 securely connects the housing 51 and the terminal 522 together. In other embodiments, the housing 51 and the terminal 522 can also be manufactured through other processes, which are not limited in the embodiments of the present application.

[0105] In the embodiment of the present application, the terminals 522 of the card connector 52 fixed to the housing 51, the insulating member 521, and the housing 51 are formed into an integral structure through an insert injection molding process. This simplifies the assembly process of the insulating member 521, the terminals 522, and the housing 51, and increases the connection strength between the insulating member 521, the terminals 522, and the housing 51, thereby increasing the structural stability of the card holder 50. In addition, if the insulating member 521 and the housing 51 are of a separate structure and are assembled and fixed by gluing or welding, a gap will exist between the insulating member 521 and the housing 51, and dust or other impurities may enter the gap. In the embodiment of the present application, by setting the terminals 522 of the card connector 52 fixed to the housing 51, the insulating member 521, and the housing 51 as an integral structure through an insert injection molding process, there is no gap between the insulating member 521 and the housing 51, thereby preventing foreign matter from being present between the insulating member 521 and the housing 51.

[0106] See Figure 13, the number of electronic cards 60 is two, and the two electronic cards 60 can be arranged along the second direction A2 and placed in the card tray 53 at intervals. For example, the card tray 53 includes two card slots 531 arranged along the second direction A2, and the two electronic cards 60 are placed in the two card slots 531 respectively. The card tray 53 can be moved out of or into the second slot 501. Both electronic cards 60 can be inserted into the card holder 50 horizontally. It should be noted that Figure 13 In the angle state of the structure shown, an electronic card 60 and a card slot 531 can be shown. It can be understood that an electronic card 60 and a card slot 531 are also provided on the other side of the card tray 53. Figure 13 Not shown.

[0107] When the card tray 53 is located in the second slot 501, the terminals 522 of one card connector 52 are corresponding to one card slot 531, and the terminals 522 of the other card connector 52 are corresponding to the other card slot 531. This allows the terminals 522 of one card connector 52 to be electrically connected to one electronic card 60, while the terminals 522 of the other card connector 52 are electrically connected to the other electronic card 60. The two electronic cards 60 can operate independently without interfering with each other.

[0108] In some embodiments, the card tray 53 is provided with a carrier plate ( Figure 13 (not shown), two electronic cards 60 are located on opposite sides of the carrier plate. The carrier plate needs to have sufficient rigidity to support the two electronic cards 60.

[0109] In the embodiment of the present application, by setting the number of card connectors 52 to two and the number of electronic cards 60 to two, the two electronic cards 60 are stacked and arranged in the second direction A2 and inserted horizontally into the card holder 50, which is conducive to reducing the overall size of the card holder 50, avoiding the card holder 50 and the electronic card 60 from occupying too large an area in the electronic device 100, and improving the integration of the electronic device 100.

[0110] In some embodiments, see Figure 13 、 Figure 14 and Figure 16 , Figure 16 Schematic diagram of the structure of another terminal 522. Figure 16 The terminal 522 in the figure is a terminal 522 of the card connector 52 fixed to the housing 51. The terminal 522 of the card connector 52 fixed to the housing 51 includes a pin 528, one end of the pin 528 is fixedly connected to the fixing portion 523, and the other end of the pin 528 extends out of the insulating member 521 and is fixed to the circuit board 40, and the pin 528 is electrically connected to the circuit board 40. Figure 14In the example, the number of terminals 522 of the card connector 52 fixed to the shell 51 is six, and the number of pins 528 is also six. In other implementations, the number of terminals 522 can also be four, eight or nine, etc., and this embodiment of the present application does not limit this.

[0111] See Figure 14 The housing 51 may have a hollow region 502, which is a hollow area. The main body 527 of the terminal 522 is disposed corresponding to the hollow region 502. The corresponding arrangement of the main body 527 of the terminal 522 with the hollow region 502 can be understood as meaning that the projection of the main body 527 of the terminal 522 on the plane of the bottom plate 514 of the housing 51 is located in the hollow region 502. It can be understood that the insulating member 521 has a hollow region corresponding to the hollow region 502 for accommodating the main body 527 of the terminal 522.

[0112] It is understandable that when the card tray 53 is inserted into the housing 51, the card tray 53 will exert a force on the terminal 522 of the card connector 52 fixed to the housing 51 in the direction toward the bottom plate 514, causing the main body 527 of the terminal 522 to deform and approach the bottom plate 514. The main body 527 of the terminal 522 will contact the metal housing 51, causing a short circuit. In the embodiment of the present application, the hollow area 502 is provided, so that when the terminal 522 is subjected to a force in the direction toward the bottom plate 514, it will not contact the bottom plate 514 of the housing 51, thereby preventing the terminal 522 from contacting the housing 51 when the card tray 53 is inserted. In addition, the hollow area 502 can reduce the weight of the housing 51, which is conducive to achieving a lightweight design of the card holder 50.

[0113] In some embodiments, see Figure 14 The hollow areas corresponding to the three terminals 522 arranged side by side along the insertion direction A3 can be connected, which is beneficial to the lightweight of the card holder 50.

[0114] See Figure 14 and Figure 15 The bottom plate 514 of the housing 51 is provided with a reinforcement hole 503. The insulating member 521 of the card connector 52, which is fixed to the bottom plate 514, includes an insulating body 5212 and an extension 5213. The insulating body 5212 is fixed to the surface of the bottom plate 514, and the extension 5213 is embedded in the inner wall of the reinforcement hole 503. In this embodiment of the application, the extension 5213 is embedded in the inner wall of the reinforcement hole 503 to facilitate a reliable connection between the insulating member 521 and the housing 51. In other embodiments, the housing 51 may be provided with a reinforcement groove, and the extension 5213 is located in the reinforcement groove.

[0115] It is understandable that in the embodiment of the present application, the hollow area 502 and the reinforcement hole 503 may have the same structure. In other embodiments, the hollow area 502 and the reinforcement hole 503 may also have different structures.

[0116] See Figure 14 The insulating member 521 of the card connector 52 fixed to the base plate 514 is provided with a recess 5214, and the mounting portion 5511 of the first clamping member 551 is provided with a protrusion 5519, which is located within the recess 5214. It is understandable that during the insertion and removal of the card tray 53, the first clamping member 551 is subjected to a force exerted by the card tray 53 along the insertion direction A3. This may cause the connection strength between the first clamping member 551 and the housing 51 to decrease after multiple insertions and removals of the card tray 53, resulting in a risk of the first clamping member 551 detaching from the housing 51. In this embodiment of the present application, by arranging the protrusion 5519 of the first clamping member 551 within the recess 5214 of the insulating member 521, the insulating member 521 can limit and support the first clamping member 551, thereby preventing the first clamping member 551 from detaching from the housing 51 after multiple insertions and removals of the card tray 53.

[0117] In other embodiments, the insulating member 521 of the card connector 52 fixed to the base plate 514 may be provided with a protrusion, and the mounting portion 5511 of the first clamping member 551 may be provided with a recess, with the protrusion located within the recess.

[0118] In some embodiments, the mounting portion 5511 of the first clamping member 551 can be located between the base plate 514 and the insulating member 521 of the card connector 52 fixed to the base plate 514, which is beneficial for the insulating member 521 to limit and support the first clamping member 551, thereby preventing the first clamping member 551 from being separated from the shell 51 after multiple plugging and unplugging of the card tray 53.

[0119] See Figure 14 and Figure 17 , Figure 17 for Figure 13 The schematic diagram of a partial structure of the card holder 50 is shown. The housing 51 is provided with a bridge 505, which is located within the housing 51. The bridge 505 includes an embedding portion 506, a first end 507, and a second end 508. The first end 507 and the second end 508 are arranged opposite each other, and both the first end 507 and the second end 508 are fixed to the base plate 514. The embedding portion 506 is located between the first end 507 and the second end 508. A gap is provided between the embedding portion 506 and the base plate 514, and the embedding portion 506 is embedded in the insulating member 521 of the card connector 52 fixed to the base plate 514. It can be understood that the embedding portion 506 embedded in the insulating member 521 of the card connector 52 fixed to the base plate 514 helps to increase the connection strength between the insulating member 521 of the card connector 52 fixed to the base plate 514 and the housing 51, thereby improving the reliability of the connection.

[0120] In some embodiments, the housing 51 may include a filling hole 504 , the first end 507 and the second end 508 are both fixed to the edge of the filling hole 504 , and a portion of the insulating member 521 may be disposed in the filling hole 504 .

[0121] In other embodiments, the card connector 52 may include eight terminals, which may include six triangular terminals 522 and two strip-shaped terminals, so that the card holder 50 can be installed with a SIM card and an NM card. The strip-shaped terminal may include a contact portion and two fixing portions, the contact portion being located between the two fixing portions, and both fixing portions being fixed to the insulating member. For example, the six triangular terminals 522 refer to FIG. Figure 6 The card connector 52 includes six triangular terminals 522, two elongated terminals secured to the insulator 521 and positioned around the six triangular terminals 522. The card connector 52, equipped with the six triangular terminals 522 and two elongated terminals, can be electrically connected to an NM card. The eight terminals are electrically connected to the eight chip pins on the NM card. In other embodiments, the card connector 52 may include more or fewer than eight terminals to correspond to the chip pins on the corresponding NM card.

[0122] It can be understood that the two electronic cards 60 in the embodiment of the present application can both be SIM cards, or one electronic card 60 can be a SIM card and the other electronic card 60 can be an NM card. The two electronic cards 60 can also be other types of electronic cards, which is not limited in this application.

[0123] The card holder 50 of the present embodiment allows for the horizontal insertion of the electronic card 60, which helps reduce the size of the card holder 50 in the insertion direction A3, facilitates the overall miniaturization of the card holder 50, and improves the space utilization of the electronic device 100. The number of elastic arms 524 in the present embodiment is at least two, which can increase the structural stability of the terminal 522 and improve the reliability of the electrical connection between the terminal 522 and the electronic card 60. By providing the first clamping member 551 and the housing 51 as separate structures, the size of the first clamping member 551 is no longer restricted by the structure of the push rod 54 connected to the housing 51. The first clamping member 551 can be longer in the insertion direction A3, avoiding the first clamping member 551 being too short, which would result in excessive clamping force on the card tray 53, making it difficult to move the card tray 53, and avoiding excessive material loss in the first clamping member 551 due to excessive clamping force on the card tray 53.

[0124] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
