Description

Technical Field

[0001] This application relates to the field of electronic product technology, and more particularly to a card holder and an electronic device. Background Technology

[0002] The development of electronic devices has changed our lifestyles, especially the development of tablets and mobile phones, which have brought great convenience to our lives. Electronic devices typically have a card slot for installing electronic cards, enabling the device's communication and storage functions. The card slot has a card tray on which the electronic card is placed. A clamping mechanism within the card slot is used to hold the card tray. Excessive clamping force on the card tray can lead to difficulty in inserting and removing the card, and can also cause significant material wear on the clamping mechanism itself. Summary of the Invention

[0003] This application provides a card holder and an electronic device. By rationally designing the structure of the card holder, this application achieves miniaturization and avoids the problems of difficulty in inserting and removing the card tray due to excessive clamping force of the clamping mechanism, as well as severe material wear of the clamping mechanism.

[0004] In a first aspect, embodiments of this application provide a card holder. The card holder is applied to an electronic device, which includes an electronic card. The card holder includes a housing, a card connector, a card tray, and a clamping mechanism. The card tray is movable into or out of the housing, and the card tray has a card slot, the extension direction of the short side of which is the same as the insertion direction of the card tray. The electronic card is located in the card slot. The housing can be made of metal, such as iron, copper, or aluminum.

[0005] Understandably, having the short side of the card slot extend in the same direction as the insertion direction of the card tray allows the electronic card to be inserted horizontally into the card slot. Horizontal insertion of the electronic card into the card slot helps reduce the size of the card slot in the insertion direction, promotes overall miniaturization of the card slot, reduces the space occupied by the card slot in the electronic device, reserves sufficient space for the installation of batteries and other components within the electronic device, and improves the space utilization rate of the electronic device.

[0006] The card connector is located within the housing. The card connector includes an insulating component and terminals. Each terminal includes a fixing portion, at least two spring arms, and a contact portion. The fixing portion is fixed to the insulating component, and the contact portion is spaced apart from the fixing portion. At least two spring arms are fixedly connected between the fixing portion and the contact portion, and the arrangement direction of the at least two spring arms forms an angle with the arrangement direction of the fixing portion and the contact portion. When the card tray is located within the housing, the contact portion corresponds to the card slot. The number of spring arms can be two, three, four, or five, etc., and multiple spring arms can be arranged side-by-side on the same side of the contact portion. The terminal can be a one-piece molded structure, which simplifies the manufacturing process and provides high structural strength. In other embodiments, the multiple structural components of the terminal can also be separate structures assembled and fixed to form the terminal. The insulating component can be made of materials 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 this embodiment, increasing the number of spring arms enhances the structural strength and stability of the terminal, which is beneficial for 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 disposed opposite to each other along a first direction, the first direction forming an angle with the insertion direction. When the card tray is moved into the housing, the card tray 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] Understandably, when the card slot allows for horizontal insertion of electronic cards, the smaller dimensions of the housing in the insertion direction result in smaller dimensions of the first and second clamping components in the same direction. If the first clamping component is integrally formed with the housing, its size will be further limited by certain structural features of the housing, making it difficult to increase its size. Excessively small dimensions of the first and second clamping components in the insertion direction lead to excessive clamping force on the card tray, making it difficult for the card tray to be moved into or out of the housing. Furthermore, during the process of moving the card tray into or out of the card slot, the first and second clamping components deform. Their excessively small dimensions result in significant material wear during repeated card tray movements, reducing their lifespan.

[0009] This embodiment of the application, by setting the first clamping member and the housing as separate structures, eliminates the size limitations of the first clamping member, which is not restricted by the structures on the housing. The first clamping member can be set to be longer in the insertion direction, avoiding excessive clamping force on the card tray that would make it difficult for the card tray to move, and preventing excessive material wear on the first clamping member. This embodiment of the application, by setting the first clamping member and the housing as separate structures, allows for high flexibility in setting the size, thickness, material, etc., of the first clamping member.

[0010] In one possible implementation, 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 housing, and the clamping portion is used to clamp the card tray. The first connecting portion connects one end of the mounting portion to one end of the clamping portion, and the second connecting portion connects the other end of the mounting portion to the other end of the clamping portion. The distance between the first connecting portion and the second connecting portion is greater than or equal to 4 mm. For example, the distance between the first connecting portion and the second connecting portion 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 as needed. By setting the distance between the first connecting portion and the second connecting portion to be greater than or equal to 4 mm, this embodiment of the application can ensure the size of the first clamping member in the insertion direction, avoiding the situation where the size of the first clamping member in the insertion direction is too short, resulting in excessive clamping force on the card tray, making it difficult for the card tray to be moved out or into the housing. In addition, by setting the distance between the first connecting part and the second connecting part to be greater than or equal to 4mm, it is beneficial to avoid the first clamping part being too small, which would cause severe material wear and reduce the service life of the first clamping part during the repeated removal and insertion of the card tray.

[0011] In one possible implementation, the mounting portion is bent toward one side of the clamping portion relative to the clamping portion. In this embodiment, by setting the mounting portion to bend 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 beneficial for miniaturizing the card holder.

[0012] In one possible implementation, the mounting portion is provided with a first positioning portion, and the housing is provided with a second positioning portion, the first positioning portion and the second positioning portion cooperating with each other. By providing the first positioning portion and the second positioning portion to cooperate, the first clamping member can be quickly and accurately fixed to the housing. The number of first positioning portions can be one or more, and the number of second positioning portions can also be one or more; "multiple" can be understood as two or more. When there are multiple first positioning portions, they are spaced apart. The multiple first positioning portions can be configured with structures of different sizes or shapes to achieve positioning of the first clamping member and the housing, avoiding positioning errors and facilitating direct and accurate positioning.

[0013] In one possible implementation, the first positioning part is a protrusion, and the second positioning part is a groove or opening; alternatively, the first positioning part is a groove or opening, and the second positioning part is a protrusion, with the protrusion located within the groove or opening. By providing a protrusion that engages with the groove or opening, it facilitates the quick and precise fixing of the first clamping member to the housing. Understandably, the protrusion can be a dot, a pillar, or a conical protrusion, etc.

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

[0015] In one possible implementation, the card holder includes a push rod slidably connected to the housing, the push rod being used to push the card tray out of the housing; when the card tray moves into the housing, the first clamping member and the push rod are located on the same side of the card tray, with the first clamping member 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 is integrally formed with the housing, the size of the first clamping member will be limited by the structure on the housing used to connect the push rod, making it difficult to increase its size. This embodiment of the application sets the first clamping member and the housing as a separate structure, so the size of the first clamping member is not limited by the structure on the housing used to connect the push rod. The dimension of the first clamping member in the insertion direction can be set to be longer, avoiding excessive clamping force on the card tray that would make it difficult for the card tray to move and avoiding excessive material consumption of the first clamping member.

[0016] In one possible implementation, the housing includes a folded portion, and the push rod is located within a track formed by the folded portion. The folded portion includes a first end and a second end disposed opposite to each other along the insertion direction, with a cutout between the first end and the second end. 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 is understood that the first clamping member and the housing are separate structures, and the size of the first clamping member is not limited by the structure (folded portion) on the housing used to connect the push rod. 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, this embodiment of the application facilitates ensuring that the size of the first clamping member in the insertion direction can be set relatively large.

[0017] In one possible implementation, the second clamping member and the housing are separate structures, with the second clamping member assembled and fixed to the housing. Exemplarily, the second clamping member can be assembled and fixed to the housing by welding or gluing. This embodiment of the application, by setting the second clamping member and the housing as separate structures, allows for high flexibility in the size, thickness, and material of the second clamping member. In other implementations, the second clamping member and the housing can be an integrally formed structure, eliminating the need for a fixed connection, which simplifies the process and improves the structural strength and stability of the second clamping member and the housing.

[0018] In one possible implementation, the contact portion between the clamping part of the second clamping member and the card tray is designated as the second portion, and the contact portion between the clamping part of the first clamping member and the card tray is designated as the first portion. The line connecting the first portion and the second portion is parallel to the long side of the card slot. This embodiment ensures uniform clamping force on both sides of the card tray by setting the line connecting the first portion and the second portion parallel to the long side of the card slot, thus preventing uneven force distribution and instability of the card tray within the card holder.

[0019] In one possible implementation, the second clamping member has the same dimension in the insertion direction as the first clamping member in the insertion direction to ensure that the card tray receives uniform clamping force on both sides and avoid instability of the card tray within the card holder due to uneven force on both sides. The dimension of the second clamping member is not limited by the structure connecting the push rod on the housing, allowing for high flexibility in dimension setting. In other embodiments, the dimension of the second clamping member in the insertion direction may also differ from that of the first clamping member in the insertion direction; this application does not limit this aspect.

[0020] In one possible implementation, the main body of the terminal includes at least two spring arms and a contact portion. The main body protrudes relative to the surface of the fixing portion, and the outer edge of the main body is bent in the opposite direction to the protrusion direction of the main body. By setting the outer edge of the main body to bend in the opposite direction to the protrusion direction of the main body, this embodiment of the application helps to avoid damage to the electronic card by the outer edge of the terminal during the insertion and removal of the electronic card. It is understood that the surface of the main body facing the electronic card can be a smooth curved surface to prevent damage to the electronic card by the terminal.

[0021] In one possible implementation, there are two card connectors, which are spaced apart from each other along a second direction to form slots. The second direction forms an angle with the insertion direction and with the first direction. There are also two card slots, arranged along the second direction. When the card tray is located in the slot, the terminal of one card connector corresponds to one of the card slots, and the terminal of the other card connector corresponds to the other card slot. In this embodiment, by using two card connectors and two card slots (i.e., two electronic cards), and arranging them stacked in the second direction and inserted laterally, the overall size of the card holder is reduced, preventing it from occupying too much area within the electronic device and improving its integration.

[0022] In one possible implementation, the first clamping member is assembled and fixed to the base plate of the housing, and one of the card connectors is fixed to the base plate. 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 act as inserts, integrally formed with the insulating member. In this embodiment, the terminal of the card connector fixed to the housing and the housing are molded into an integral structure through insert injection molding, simplifying the assembly process of the insulating member, terminal, and housing, and resulting in high connection strength between the insulating member, terminal, and housing, increasing the structural stability of the card holder. Furthermore, if the insulating member and the housing are separate structures and assembled and fixed by adhesive or welding, gaps may exist between the insulating member and the housing, potentially allowing dust or other impurities to enter. In this embodiment, by setting the terminal of the card connector fixed to the housing, the insulating member, and the housing to be molded into an integral structure through insert injection molding, there are no gaps between the insulating member and the housing, preventing foreign objects from entering between them.

[0023] In one possible implementation, the insulating member of the card connector fixed to the base plate has a recess, and the first clamping member has a protrusion; or, the insulating member of the card connector fixed to the base plate has a protrusion, and the first clamping member has a recess, with the protrusion located within the recess. Understandably, during the insertion and removal of the card tray, the first clamping member is subjected to a force from the card tray along the insertion direction. This may cause the connection strength between the first clamping member and the housing to decrease after repeated insertions and removals, potentially leading to the risk of the first clamping member detaching from the housing. This embodiment addresses this by providing a protrusion located within the recess, allowing the insulating member to constrain and support the first clamping member, preventing it from detaching from the housing after repeated insertions and removals.

[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. By positioning a portion of the first clamping member between the base plate and the insulating member of the card connector fixed to the base plate, this embodiment of the application facilitates the insulating member's ability to constrain and support the first clamping member, preventing the card tray from detaching from the housing after repeated insertions and removals.

[0025] In one possible implementation, the housing is provided with a bridge, the bridge including an embedding portion and a first end and a second end disposed opposite to each other, the embedding portion being located between the first end and the second end; both the first end and the second end are fixed to the base plate, a gap is provided between the embedding portion and the base plate, and the embedding portion is embedded within the insulating member of the card connector fixed to the base plate. In this embodiment, by providing an embedding portion 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 implementation, the base plate is provided with a reinforcing hole or a reinforcing groove. The insulating component of the card connector fixed to the base plate includes an insulating body and an extension. The insulating body is fixed to the surface of the base plate, and the extension is embedded in the reinforcing hole or the reinforcing groove. In this embodiment, the extension being embedded in the inner wall of the reinforcing hole facilitates a reliable connection between the insulating component and the housing.

[0027] In one possible implementation, the main body of the terminal includes at least two spring arms and the contact portion, the housing includes a cutout area, and the main body is correspondingly disposed with the cutout area. One of the card connectors is fixed to the bottom plate of the housing. The correspondence between the main body of the terminal and the cutout area can be understood as the projection of the main body of the terminal onto the plane of the bottom plate of the housing being located in the cutout area. During the insertion of the card tray into the housing, the card tray exerts a force on the terminal towards the bottom plate, causing the main body of the terminal to deform and move closer to the bottom plate. Contact between the main body of the terminal and the metal housing can lead to a short circuit. In this embodiment, by providing the cutout area, the terminal will not contact the housing when subjected to a force towards the bottom plate, thus preventing short circuits caused by contact between the terminal and the housing during card tray insertion. Furthermore, providing the cutout area can reduce the weight of the housing, which is beneficial for achieving a lightweight design of the card holder.

[0028] Secondly, this application provides an electronic device, including a circuit board and a card holder as described in any of the foregoing embodiments. 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 tablet computer, or a candybar phone or a foldable phone, etc. A candybar phone can be understood as a non-foldable device. The electronic card can be a data card, a Subscriber Identity Module (SIM), or a Nano Memory Card (NM), etc., and this application does not limit the specific type of card.

[0029] In one possible implementation, the electronic device includes a housing, with the circuit board and the card holder both located within the housing. An opening is provided on the short side of the housing for the card holder to extend out of the housing. In other embodiments, the opening on the housing for removing or inserting the electronic card into the electronic device may also be located on the long side of the housing. This application does not limit this provision and the opening can be configured as needed.

[0030] The card holder in this embodiment allows for horizontal insertion of electronic cards, which helps reduce the size of the card holder in the insertion direction and contributes to the overall miniaturization of the card holder. This embodiment has at least two spring arms, increasing the structural stability of the terminals. By designing the first clamping member and the housing as separate structures, this embodiment offers high flexibility in the size setting of the first clamping member. The dimension of the first clamping member in the insertion direction can be set to be relatively long, avoiding excessive clamping force on the card tray that would make the card tray difficult to move and preventing excessive material wear on the first clamping member.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, a mating connection, or an integral connection; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an electronic device 100. The electronic device 100 can be a mobile phone or a tablet computer, etc. The electronic device 100 can be a candybar phone or a foldable phone, etc. A candybar phone can be understood as a non-foldable device. This application embodiment takes a candybar phone as an example for the description of the electronic device 100.

[0054] Electronic device 100 may include housing 10, display screen ( Figure 1 (Not shown) Camera module 20, battery 30, circuit board 40, and card slot 50. Electronic card 60 can be installed in the card slot 50 of electronic device 100 to realize communication or storage functions of electronic device 100. Housing 10 may include frame 11 and back cover 12. The back cover 12 may be integrally formed with frame 11, or it may be a separate structure and formed into an integral structure by assembly (e.g., glued connection). Display screen and back cover 12 are respectively installed on both sides of frame 11, together enclosing the inner cavity of the whole device, for installing camera module 20, battery 30, circuit board 40, card slot 50, electronic card 60 or other structural components. Display screen can be used to display images to meet user needs.

[0055] The camera module 20 can be mounted on the rear cover plate 12 as a rear camera of the electronic device 100. The rear cover plate 12 may have openings through which the camera module 20 collects light to capture images or videos. For example, the rear cover plate 12 may include a light-transmitting lens mounted in the openings to allow light to pass through and to provide dust and water resistance. In some other embodiments, the camera module 20 may also serve as a front camera of the electronic device 100.

[0056] Battery 30 can power electronic device 100. Battery 30 can be a lithium battery or a nickel-metal hydride battery, etc. The size of battery 30 affects its capacity. The larger the size of battery 30, the larger its capacity can be, and the longer the battery life of electronic device 100. Battery 30 can be square, round, or irregularly shaped, etc., and this application embodiment does not limit this.

[0057] Card holder 50 is fixed to circuit board 40. Card holder 50 includes card tray 53. Figure 1 Not shown, see reference Figure 3 The electronic card 60 can be installed on the card tray 53 or removed from the card tray 53. The electronic card 60 can be stored in the card holder 50 or removed from the card holder 50.

[0058] For example, the frame 11 of the housing 10 may be provided with openings ( Figure 1 (Not shown), the card tray 53 can extend from or into the frame 11 through the opening, meaning the electronic card 60 can extend from or into the frame 11 through the opening. In some embodiments, the frame 11 may include a first side 111, a second side 112, a third side 113, and a fourth side 114 connected in sequence. The first side 111 and the third side 113 are arranged opposite each other, and the length of the first side 111 may be the same as the length of the third side 113. The second side 112 and the fourth side 114 are arranged opposite each other, and the length of the second side 112 and the length of the fourth side 114 may be the same. The length of the first side 111 is greater than the length of the second side 112. The first side 111 is the long side of the electronic device 100, and the second side 112 is the short side of the electronic device 100. The fourth side 114 is located at the top of the electronic device 100, and the second side 112 is located at the bottom of the electronic device 100. The opening of the frame 11 may be provided on the second side 112, meaning the electronic card 60 can be removed from or installed into the card tray 53 from the bottom of the electronic device 100. The second side 112 may also be provided with a hole for inserting a charging plug, a hole corresponding to a speaker, etc. In the embodiments of this application, the opening for removing or installing the electronic card 60 is set at the bottom of the electronic device 100, which is beneficial to the centralized distribution of the openings of the electronic device 100 and improves the appearance of the electronic device 100.

[0059] In other embodiments, the openings on the frame 11 for the electronic card 60 to be removed from or inserted into the electronic device 100 may also be provided on the first side 111, the third side 113, or the fourth side 114, etc. This application embodiment does not limit this and can be set as needed.

[0060] In some embodiments, the electronic card 60 may be a data card, a Subscriber Identity Module (SIM) or a Nano Memory Card (NM), etc., and this application embodiment does not limit this.

[0061] Figure 1 The electronic device 100 in this embodiment is only schematic. 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. This application does not limit the specific structure of the electronic device 100.

[0062] like Figure 2 , Figure 3 and Figure 4 As shown, Figure 2 for Figure 1 The diagram shows the structure of the card holder 50 and the electronic card 60. Figure 3 for Figure 2 The diagram shows another angle of the card holder 50 and the electronic card 60. Figure 4 for Figure 3 An exploded view of the card holder 50 and electronic card 60 shown.

[0063] The card holder 50 may include a housing 51, a card connector 52, a card tray 53, and a clamping mechanism 55. The housing 51 may include a first side portion 511, a second side portion 512, a third side portion 513, a base plate 514, and an opening side portion 515. The first side portion 511, the second side portion 512, and the third side portion 513 are sequentially arranged around the edge of the base plate 514 to form a receiving cavity 516. The first side portion 511 and the third side portion 513 are arranged opposite to each other, and the opening side portion 515 is arranged opposite to the second side portion 512. The card tray 53 can be moved out of the housing 51 or into the housing 51 from the opening side portion 515.

[0064] In some embodiments, the lengths of the first side portion 511 and the third side portion 513 may be the same, and the lengths of both the first side portion 511 and the third side portion 513 may be less than the length of the second side portion 512. It is understood 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 embodiments of this application do 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 serve a shielding function, protecting the electronic card 60 from external signal interference and preventing the electronic card 60's signal from interfering with other signals of the electronic device 100. The housing 51 also enhances the overall structural strength of the card holder 50.

[0066] The card connector 52 is located inside the housing 51 and can be spaced apart from the base plate 514 of the housing 51. A first slot 517 is formed between the card connector 52 and the base plate 514 of the housing 51. The first slot 517 is used to receive the card tray 53. In other words, the card tray 53 can be located inside the first slot 517. Understandably, the first slot 517 can be part of the receiving cavity 516.

[0067] The card connector 52 may include an insulating component 521 and terminals 522 for fixed connection. The insulating component 521 may be made of a material such as plastic. The insulating component 521 serves to connect multiple terminals 522 ( Figure 3 (Taking six terminals 522 as an example) The terminals 522 serve to insulate each other and to insulate the terminals 522 from other structural components that do not require electrical connection. For example, the insulating component 521 can insulate the terminals 522 from the metal housing 51.

[0068] See Figure 5 and Figure 6 , Figure 5 for Figure 4 The schematic diagram of terminal 522 shown is as follows. Figure 6 for Figure 4 The diagram shows the structure of the card connector 52. It should be noted that... Figure 5 Terminal 522 in Figure 6 The viewing angle of terminal 522 is different. Figure 5 Terminal 522 is the view of terminal 522 facing the electronic card 60. Figure 6Terminal 522 is viewed from the side of terminal 522 away from electronic card 60. Terminal 522 may include a fixing part 523, at least two spring arms 524, and a contact part 525. The fixing part 523 is fixed to the insulating member 521, and the contact part 525 is spaced apart from the fixing part 523, such that there is a gap between the contact part 525 and the fixing part 523, or other structures can be provided between the contact part 525 and the fixing part 523. At least two spring arms 524 are located on the same side of the contact part 525 and are spaced apart, and each spring arm 524 is fixedly connected between the fixing part 523 and the contact part 525. The contact part 525 is elastically protruding relative to the surface of the insulating member 521. Understandably, when the card tray 53 is located inside the housing 51, the contact part 525 is correspondingly provided with the card slot 531, and the contact part 525 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 follows: when the card holder 53 is located inside the housing 51, the projection of the contact portion 525 on the plane where the card holder 53 is located is located inside the card slot 531.

[0069] Understandably, the number of spring arms 524 can be two, three, four, or five, etc., with multiple spring arms 524 arranged side by side on the same side of the contact portion 525. In this embodiment, increasing the number of spring arms 524 enhances the structural strength and stability of the terminal 522, which is beneficial for a stable electrical connection between the terminal 522 and the electronic card 60.

[0070] In some embodiments, the arrangement direction of at least two spring arms 524 is at an angle to the arrangement direction of the fixing part 523 and the contact part 525. This facilitates the miniaturization of the terminal 522 as a whole, avoids the terminal 522 occupying too much space in the card holder 50, and promotes the miniaturization of the card holder 50. For example, the arrangement direction of at least two spring arms 524 may be perpendicular to the arrangement direction of the fixing part 523 and the contact part 525.

[0071] In some embodiments, the fixing part 523, at least two spring arms 524 and the contact part 525 can be triangular in shape. 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 6Terminal 522 may also include a welding portion 526, one end of which is fixed to the fixing portion 523, and the other end of which can be welded to the circuit board 40. When the card holder 50 is installed on 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, realizing the fixed connection and electrical connection between the card connector 52 and the circuit board 40. Understandably, the welding portion 526 can be located between two adjacent spring arms 524, making full and reasonable use of the structural space of the terminal 522, which is conducive to the miniaturization of the terminal 522. Understandably, the terminal 522 can be a one-piece molded structure, which is conducive to simplifying the manufacturing process and has high structural strength. In other embodiments, the multiple structural components of the terminal 522 can also be a separate structure and assembled and fixed to form the terminal 522.

[0073] See Figure 3 , Figure 5 and Figure 6 The main body 527 of terminal 522 includes at least two spring arms 524 and a contact portion 525. The main body 527 protrudes from the surface of the fixing portion 523. The main body 527 includes an outer edge 5271 and an inner edge 5272, with the outer edge 5271 bent relative to the inner edge 5272 in a direction opposite to the protruding direction of the main body 527. By providing that the outer edge 5271 bends relative to the inner edge 5272 in a direction opposite to the protruding direction of the main body 527, this embodiment of the application helps to prevent damage to the electronic card 60 by the outer edge 5271 of terminal 522 during the 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 damage to the electronic card 60 by terminal 522.

[0074] See Figures 2 to 4 The card tray 53 can be located within the first slot 517 or removed from the first slot 517. The card tray 53 has a card slot 531 into which the electronic card 60 can be installed. The electronic card 60 can be generally rectangular, and can 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, allowing the electronic card 60 to be inserted laterally into the card holder 50. The ability of the electronic card 60 to be inserted laterally into the card holder 50 can be understood as follows: during the insertion of 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. The horizontal insertion of the electronic card 60 into the card holder 50 helps to reduce the size of the card holder 50 in the insertion direction A3, which is conducive to the overall miniaturization of the card holder 50, reduces the space occupied by the card holder 50 in the electronic device 100, reserves sufficient space for the battery 30 and other installations, and improves 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 disposed opposite to each other along a first direction A1. The first direction A1 is set 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 inside the housing 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 is removed from the card holder 50, it needs 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 is moved 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 within the card holder 50, at which point the first clamping member 551 and the second clamping member 552 stably place the card tray 53 within the card holder 50.

[0076] The first clamping member 551 and the housing 51 can be separate structures, with the first clamping member 551 assembled and fixed to the housing 51. For example, the first clamping member 551 can be fixed to the housing 51 by welding or gluing.

[0077] In some embodiments, the dimensions of the second clamping member 552 in the insertion direction A3 may be the same as those of the first clamping member 551 in the insertion direction A3, to ensure that the card tray 53 is subjected to uniform clamping force on both sides, and to avoid instability of the card tray 53 within the card holder 50 due to uneven force on both sides of the card tray 53. The dimensions of the second clamping member 552 are not limited by the structure of the push rod 54 connected to the housing 51, and the size setting is highly flexible. In other embodiments, the dimensions of the second clamping member 552 in the insertion direction A3 may also be different from those of the first clamping member 551 in the insertion direction A3, and this application embodiment does not limit this.

[0078] Understandably, when the card holder 50 allows the electronic card 60 to be inserted horizontally, the size of the housing 51 in the insertion direction A3 is smaller, that is, the sizes of the first side portion 511 and the third side portion 513 in the insertion direction A3 are smaller (understandably, the sizes of the first side portion 511 and the third side portion 513 in the insertion direction A3 are smaller than the size of the second side portion 512 in the first direction A1), which will result in the sizes of the first clamping member 551 and the second clamping member 552 being smaller in the insertion direction A3. If the first clamping member 551 is integrally formed with the housing 51, the size of the first clamping member 551 will be affected by the structure on the housing 51 used to connect the push rod 54 (see...). Figure 7 and Figure 8Due to the limitations of the folding portion 518 shown, its size is difficult to increase. If the dimensions of the first clamping member 551 and the second clamping member 552 in the insertion direction A3 are 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 housing 51 or to remove the card tray 53 from the housing 51. In addition, during the process of the card tray 53 being moved out or into the card holder 50, the first clamping member 551 and the second clamping member 552 will deform. If the dimensions of the first clamping member 551 and the second clamping member 552 are too small, the material wear of the first clamping member 551 and the second clamping member 552 will be severe during the repeated movement of the card tray 53, 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 diagram shows a partial structural design of the card holder 50. Figure 8 for Figure 7 This is a schematic diagram of the partial structure of the card holder from another angle. The housing 51 is provided with a folding portion 518, which can be part of the third side portion 513. The folding portion 518 is used to form a track 5183 that allows 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 folding portion 518. The folding portion 518 can limit the push rod 54 in the first direction A1, preventing the push rod 54 from moving in the first direction A1 and improving the structural stability of the card holder 50.

[0080] In some embodiments, the folding portion 518 may include a first end portion 5181 and a second end portion 5182 arranged along the insertion direction A3, with the first end portion 5181 and the second end portion 5182 spaced apart and hollowed out between them. If the first clamping member 551 is integrally formed with the housing 51, the two ends of the first clamping member 551 are limited by the space between the first end portion 5181 and the second end portion 5182, making it difficult to make the size of the first clamping member 551 large in the insertion direction A3, and it is usually small. In the embodiments of this application, the first clamping member 551 and the housing 51 are separate structures, 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 portion 5181 and the second end portion 5182 may also be non-hollowed out, and the first end portion 5181 and the second end portion 5182 may be connected as a whole.

[0081] In this embodiment, the first clamping member 551 and the housing 51 are designed as separate structures. The size of the first clamping member 551 is not limited by the structure on the housing 51 used to connect the push rod 54. The size, thickness, material, and position of the first clamping member 551 are highly flexible. The dimension of the first clamping member 551 in the insertion direction A3 can be set to be relatively long, avoiding excessive clamping force on the card tray 53 due to an excessively small size, which would make the card tray 53 difficult to move, and also avoiding excessive material wear on the first clamping member 551. The card holder 50 in this 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, promotes overall miniaturization of the card holder 50, and improves the space utilization of the electronic device 100. This embodiment of the application achieves a miniaturized design of the terminal 522 by arranging at least two spring arms 524 at an angle to the arrangement direction of the fixing part 523 and the contact part 525, thus avoiding excessive space occupation of the card holder 50 by the terminal 522 and facilitating the miniaturization of the card holder 50. The fact that this embodiment of the application has at least two spring arms 524 increases the structural stability of the terminal 522 and improves the reliability of the electrical connection between the terminal 522 and the electronic card 60.

[0082] See Figure 4 In this embodiment, the electronic card 60 has six chip pins 63, and the number of terminals 522 is six, with each terminal 522 electrically connected to one chip pin 63. In other embodiments, the number of chip pins 63 of the electronic card 60 may be four, eight, or nine, etc., and this embodiment does not limit this. It can be understood that the number of terminals 522 can be adjusted according to the number of chip pins 63 of the electronic card 60, and the number of terminals 522 can be consistent with the number of chip pins 63.

[0083] See Figure 3 and Figure 7 The card holder 50 may include a detection mechanism 57 for detecting whether the card tray 53 is inserted. Exemplarily, the detection mechanism 57 may include an elastic element 571 and a mating element 572. The elastic element 571 includes a first end 573 and a second end 574, and the mating element 572 includes a third end 575 and a fourth end 576. During the insertion of the card tray 53 into the housing 51, the card tray 53 compresses the elastic element 571, separating the first end 573 from the third end 575. Insertion is determined by detecting an open circuit in the electrical signal between the second end 574 and the fourth end 576. During the removal of the card tray 53 from the housing 51, the elastic element 571 recovers its deformation, and the first end 573 contacts the third end 575. Removal is determined by detecting a short circuit in the electrical signal between the second end 574 and the fourth end 576.

[0084] See Figures 2 to 4The card holder 50 may include a push rod 54, which is slidably connected to the housing 51. The push rod 54 is used to push the card tray 53 out of the housing 51. Understandably, the push rod 54 can reciprocate along the insertion direction A3. When the card tray 53 is located inside the housing 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 housing 51, the size of the first clamping member 551 will also be limited by the structure on the housing 51 used to connect the push rod 54, making it difficult to make the size large. In this embodiment, the first clamping member 551 and the housing 51 are set as separate structures. The size of the first clamping member 551 is not limited by the structure on the housing 51 used to connect 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 clamping force of the first clamping member 551 on the card tray 53 being too large, which would make the card tray 53 difficult to move, and to avoid excessive material wear of the first clamping member 551.

[0085] Exemplarily, the card holder 50 may include a lever 561 and a rotating shaft 562. The rotating shaft 562 is fixed to the base plate 514 of the housing 51, and the lever 561 is rotatably connected to the rotating 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 and pushes the lever 561 to rotate along the rotating shaft 562. The other end of the lever 561 acts on the card holder 53, moving the card holder 53 out of the housing 51. When the card holder 53 is inserted into the housing 51, the card holder 53 acts on one end of the lever 561, the lever 561 rotates along the rotating shaft 562, and the other end of the lever 561 pushes the push rod 54 to move away from the second side portion 512.

[0086] Understandably, 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 can be fixed to the housing 51 by welding or gluing. By setting the second clamping member 552 and the housing 51 as separate structures, this embodiment of the application allows for greater flexibility in setting the size, thickness, material, etc., of the second clamping member 552.

[0087] See Figure 4 , Figure 7 and Figure 9 , Figure 9 for Figure 7The diagram shows the structure of the first clamping member 551. 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 base plate 514 of the housing 51, and the clamping portion 5514 is used to clamp the card tray 53. Understandably, when the card tray 53 is located within the first slot 517, the mounting portion 5511 is located between the card tray 53 and the base 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 distance L between the first connecting portion 5512 and the second connecting portion 5513 is greater than or equal to 4 mm. By setting the distance L between the first connecting portion 5512 and the second connecting portion 5513 to be greater than or equal to 4 mm, this embodiment of the application ensures that the size of the first clamping member 551 in the insertion direction A3 is maintained, preventing the clamping force of the first clamping member 551 on the card tray 53 from being too large due to an excessively short size in the insertion direction A3, making it difficult for the card tray 53 to be moved out or into the first slot 517. Furthermore, by setting the distance L between the first connecting portion 5512 and the second connecting portion 5513 to be greater than or equal to 4 mm, it helps to avoid severe material wear and reduced service life of the first clamping member 551 during repeated removal and insertion of the card tray 53, which would be caused by an excessively small size of the first clamping member 551. For example, the distance L between the first connecting part 5512 and the second connecting part 5513 can be 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm or 8mm, etc., and can be set as needed.

[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] Understandably, in some embodiments, the base plate 514 may be provided with a groove, and the mounting part 5511 is fixed to the groove on the base plate 514, which can avoid the imbalance on both sides of the card holder 53 caused by the mounting part 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 spring-loaded arm 5515, a spring-loaded segment 5516, and a second spring-loaded arm 5517 connected in sequence. The spring-loaded segment 5516 protrudes from the surfaces of the first spring-loaded arm 5515 and the second spring-loaded arm 5517. The spring-loaded segment 5516 may contact the card tray 53. During the process of the card tray 53 moving into or out of the first slot 517, the spring-loaded segment 5516 contacts and compresses the card tray 53, and the first spring-loaded arm 5515 and the second spring-loaded arm 5517 may 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 there is a cutout between the first end 5181 and the second end 5182, the surface of the first connecting portion 5512 facing the second connecting portion 5513 can be flush with the surface of the first end 5181 facing the second end 5182; or, the surface of the second connecting portion 5513 facing the first connecting portion 5512 can be flush with the surface of the second end 5182 facing the first end 5181; or, the surface of the first connecting portion 5512 facing the second connecting portion 5513 can be flush with the surface of the first end 5181 facing the second end 5182, and the surface of the second connecting portion 5513 facing the first connecting portion 5512 can be flush with the surface of the second end 5182 facing the first end 5181. It is understood that the first clamping member 551 and the housing 51 are separate structures, and the size of the first clamping member 551 does not need to be limited by the structure (folding portion 518) on the housing 51 used to connect the push rod. In this embodiment of the application, by setting the surface of the first connecting part 5512 facing the second connecting part 5513 to 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 to be flush with the surface of the second end 5182 facing the first end 5181, it is beneficial to ensure that the size of the first clamping member 551 in the insertion direction A3 can be set to be larger.

[0093] See Figure 4 , Figure 7 and Figure 9The contact portion 5521 of the second clamping member 552 with the card tray 53 is the second portion 5522. The contact portion 5514 of the first clamping member 551 with the card tray 53 is the first portion 5510, which is located in the spring-loaded section 5516. The line connecting the first portion 5510 and the second portion 5522 is parallel to the long side of the card slot 531. It can be understood that the first portion 5510 and the second portion 5522 can be symmetrically distributed on opposite sides of the card tray 53. In this embodiment, by setting the line connecting the first portion 5510 and the second portion 5522 to be parallel to the long side of the card slot 531, a uniform clamping force is ensured on both sides of the card tray 53, preventing uneven force on both sides of the card tray 53 from causing instability within the card holder 50.

[0094] See Figure 10 , Figure 10 for Figure 7 The diagram shows an exploded view of part of the structure of the card holder 50. The mounting part 5511 of the first clamping member 551 is provided with a first positioning part 5518, and the housing 51 is provided with a second positioning part 519. The first positioning part 5518 and the second positioning part 519 cooperate to realize the positioning of the first clamping member 551 and the housing 51, so as to facilitate the quick and accurate fixing of the first clamping member 551 to the housing 51.

[0095] In some embodiments, the number of first positioning parts 5518 can be one or more, and the number of second positioning parts 519 can also be one or more. Multiple can be understood as two or more. Figure 10 Taking a case where there is one first positioning part 5518 and one second positioning part 519, when there are multiple first positioning parts 5518, the multiple first positioning parts 5518 are distributed at intervals. The multiple first positioning parts 5518 can be configured with structures of different sizes or shapes to achieve positioning of the first clamping member 551 and the housing 51, avoid positioning errors between the first clamping member 551 and the housing 51, and facilitate direct and accurate positioning.

[0096] See Figure 10 In some embodiments, the first positioning part 5518 can be a protrusion, and the second positioning part 519 can be an opening. The protrusion is located within the opening to position the first clamping member 551 and the housing 51, facilitating the quick and accurate fixing of the first clamping member 551 to the housing 51. Understandably, the protrusion can be a dot, a pillar, or a conical protrusion, etc. Understandably, the second positioning part 519 can also be a groove.

[0097] In other embodiments, the first positioning part 5518 can be an opening, and the second positioning part 519 can be a protrusion. The protrusion is located within the opening to position the first clamping member 551 and the housing 51, facilitating the quick and accurate fixing of the first clamping member 551 to the housing 51. Understandably, the protrusion can be a dot, a pillar, or a conical protrusion, etc. Understandably, the first positioning part 5518 can also be a groove.

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

[0099] Combination Figure 2 and Figure 3 The implementation method shown is described in the following reference. Figure 11 , Figure 12 and Figure 13 , Figure 11 This is a schematic diagram of another type of card holder 50 and electronic card 60. Figure 12 for Figure 11 The diagram shows another angle of the card holder 50 and the electronic card 60. Figure 13 for Figure 12 The diagram shows the exploded structure of the card holder 50 and the electronic card 60.

[0100] In this embodiment, there can be two card connectors 52, which are spaced apart along the second direction A2 to 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 angled with both the insertion direction A3 and the first direction A1. For example, the second direction A2 is perpendicular to both the insertion direction A3 and the first direction A1.

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

[0102] See Figure 13 The insulating member 521 fixed to the base plate 514 includes a surface 5215, a side surface 5216, and a guide surface 5217. The guide surface 5217 connects 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, which is beneficial for quick and accurate insertion of the card tray 53. The guide surface 5217 can be a plane or a curved surface, and this embodiment does not limit it.

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

[0104] In some embodiments, during the injection molding process of the insulating member 521, the terminal 522 and the housing 51 are integrally formed with the insulating member 521 as inserts. It is understood that the terminal 522 of the card connector 52 fixed to the housing 51, the insulating member 521, and the housing 51 are formed into an integral structural component through an insert injection molding process. Exemplarily, the housing 51 can be integrally formed by injection molding, with the first clamping member 551 fixed to the housing 51. The terminal 522 can also be integrally formed by injection molding, with the completed housing 51 and terminal 522 placed as inserts in the mold, and high-temperature molten plastic injected into the mold. After the plastic cools, the insulating member 521 is formed. It is understood that during the process of the insulating member 521 forming after the plastic cools, the insulating member 521 fixes the housing 51 and the terminal 522 together. In other embodiments, the housing 51 and the terminal 522 can also be manufactured by other processes, which are not limited in this application.

[0105] In this embodiment, the terminals 522 and insulating member 521 of the card connector 52 fixed to the housing 51 are integrally formed with the housing 51 through an insert injection molding process. This simplifies the assembly process of the insulating member 521, terminals 522, and housing 51, and increases the connection strength between them, thereby improving the structural stability of the card holder 50. Furthermore, if the insulating member 521 and housing 51 are separate structures assembled and fixed by adhesive or welding, gaps may exist between them, potentially allowing dust or other impurities to enter. This embodiment, by integrating the terminals 522 and insulating member 521 of the card connector 52 fixed to the housing 51 into an integral structure through an insert injection molding process, eliminates gaps between the insulating member 521 and housing 51, preventing foreign matter from entering them.

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

[0107] When the card tray 53 is located in the second slot 501, the terminal 522 of one card connector 52 is correspondingly configured with one card slot 531, and the terminal 522 of the other card connector 52 is correspondingly configured with the other card slot 531, so that the terminal 522 of one card connector 52 is electrically connected to one electronic card 60, and the terminal 522 of the other card connector 52 is electrically connected to another electronic card 60. The two electronic cards 60 can operate independently without interfering with each other.

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

[0109] In this embodiment, 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 on the second direction A2 and inserted into the card holder 50 laterally, which helps to reduce the overall size of the card holder 50, avoid the card holder 50 and electronic cards 60 occupying too much area in the electronic device 100, and improve the integration of the electronic device 100.

[0110] In some embodiments, see Figure 13 , Figure 14 and Figure 16 , Figure 16 This is a schematic diagram of another type of terminal 522. Figure 16 Terminal 522 is the 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 part 523, and the other end of the pin 528 extends out of the insulating member 521 and is fixed to the circuit board 40. The pin 528 is electrically connected to the circuit board 40. Figure 14In this embodiment, the number of terminals 522 of the card connector 52 fixed to the housing 51 is six, and the number of pins 528 is also six. In other embodiments, the number of terminals 522 may be four, eight or nine, etc. This application does not limit this.

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

[0112] Understandably, during the insertion of the card tray 53 into the housing 51, the card tray 53 exerts a force on the terminal 522 of the card connector 52 fixed to the housing 51 in the direction of the base plate 514. The main body 527 of the terminal 522 deforms and approaches the base plate 514. Contact between the main body 527 of the terminal 522 and the metal housing 51 can cause a short circuit. In this embodiment, by providing a cutout area 502, the terminal 522 will not contact the base plate 514 of the housing 51 when subjected to a force in the direction of the base plate 514, thus preventing the terminal 522 from contacting the housing 51 when the card tray 53 is inserted. In addition, by providing the cutout area 502, the weight of the housing 51 can be reduced, which is beneficial 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 weight reduction of the card holder 50.

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

[0115] Understandably, in this embodiment, the hollow area 502 and the reinforcing hole 503 can have the same structure. In other embodiments, the hollow area 502 and the reinforcing hole 503 can also have different structures.

[0116] See Figure 14 The insulating part 521 of the card connector 52, which is fixed to the base plate 514, has a recess 5214, and the mounting part 5511 of the first clamping member 551 has a protrusion 5519, which is located within the recess 5214. Understandably, during the insertion and removal of the card tray 53, the first clamping member 551 will be subjected to a force from 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 repeated insertions and removals, potentially leading to the risk of the first clamping member 551 detaching from the housing 51. In this embodiment, by setting the protrusion 5519 of the first clamping member 551 within the recess 5214 of the insulating part 521, the insulating part 521 can limit and support the first clamping member 551, preventing the first clamping member 551 from detaching from the housing 51 after repeated insertions and removals.

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

[0118] In some embodiments, the mounting portion 5511 of the first clamping member 551 may be located between the base plate 514 and the insulating member 521 of the card connector 52 fixed to the base plate 514. This is beneficial for the insulating member 521 to limit and support the first clamping member 551, and to prevent the card tray 53 from causing the first clamping member 551 to detach from the housing 51 after multiple insertions and removals.

[0119] See Figure 14 and Figure 17 , Figure 17 for Figure 13 The diagram shows a partial structural schematic of the card holder 50. The housing 51 has a bridge 505 located within it. The bridge 505 includes an insert 506, a first end 507, and a second end 508. The first end 507 and the second end 508 are oppositely disposed and both are fixed to the base plate 514. The insert 506 is located between the first end 507 and the second end 508. A gap is provided between the insert 506 and the base plate 514, and the insert 506 is embedded within the insulating member 521 of the card connector 52 fixed to the base plate 514. It is understood that the embedding of the insert 506 within the insulating member 521 of the card connector 52 fixed to the base plate 514 increases the connection strength between the insulating member 521 of the card connector 52 fixed to the base plate 514 and the housing 51, improving connection reliability.

[0120] In some embodiments, the housing 51 may include a filling hole 504, with the first end 507 and the second end 508 both fixed to the edge of the filling hole 504, and a portion of the insulating element 521 may be provided inside 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 elongated terminals, allowing the card holder 50 to accommodate SIM cards and NM cards. The elongated terminals may include a contact portion and two retaining portions, with the contact portion located between the two retaining portions, both of which are fixed to an insulating member. Exemplarily, the six triangular terminals 522 are described in [reference needed]. Figure 6 The card connector 52 has six triangular terminals 522 arranged in a central configuration, with two elongated terminals fixed to the insulating member 521 and located around the six triangular terminals 522. The card connector 52, equipped with the six triangular terminals 522 and the two elongated terminals, can be electrically connected to an NM card, with eight terminals respectively electrically connected to eight chip pins on the NM card. In other embodiments, the card connector 52 may also include more or fewer than eight terminals to correspond to the chip pins of the respective NM card.

[0122] It is understood that both electronic cards 60 in the embodiments of this application can 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, and this application does not limit them.

[0123] The card holder 50 in this 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, promotes the overall miniaturization of the card holder 50, and improves the space utilization of the electronic device 100. The number of spring arms 524 in this embodiment is at least two, which increases the structural stability of the terminal 522 and improves the reliability of the electrical connection between the terminal 522 and the electronic card 60. In this embodiment, by setting the first clamping member 551 and the housing 51 as a separate structure, the size of the first clamping member 551 is not limited by the structure of the connecting push rod 54 on the housing 51. The size of the first clamping member 551 in the insertion direction A3 can be set to be relatively long, avoiding excessive clamping force on the card tray 53 due to an excessively short first clamping member 551, which would make the card tray 53 difficult to move, and avoiding excessive material wear of 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 this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
