[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] In the related art, the terminals of the card holder are injection-molded together with the housing to form a whole, and then the card holder of the whole integrated structure is welded on the circuit board.

[0031] Since the card holder occupies a large space in the whole machine stacking and often encounters stacking bottlenecks in all directions, if the structure of the card holder is adjusted, the card holder mold needs to be remade, which is costly.

[0032] In order to solve the above technical problems, according to an embodiment of the present disclosure, a card socket, a middle frame assembly and an electronic device are provided, wherein the card socket comprises: a shell; a circuit board, the circuit board is arranged on the inner surface of the shell; and a terminal array, the terminal array is arranged on the circuit board.

[0033] The present disclosure achieves the separation of the terminal array and the shell by directly setting the terminal array on the circuit board and then setting the circuit board on the shell of the card holder, thereby improving the independence of the various components of the card holder, making each component relatively independent and variable, reducing the cost of changing the design of the card holder, and facilitating the design change of the card holder for the stacking design of the internal components of the electronic device.

[0034] It can be understood that the card holder involved in the present disclosure can be applicable to any terminal listed below.

[0035] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0036] Figure 1 The figure is a schematic diagram of the structure of a card holder according to an exemplary embodiment. Figure 2 It is a schematic diagram of the side structure of a card holder according to an exemplary embodiment. Figure 3 It is a schematic structural diagram of an upper shell according to an exemplary embodiment. Figure 4 The figure is a schematic diagram of a card holder structure including a card tray according to an exemplary embodiment.

[0037] In some embodiments, Figure 1-4 As shown, the card holder may include: a housing 100 , a circuit board 200 , and a terminal array 300 . The circuit board 200 may be disposed on the inner surface of the housing 100 , and the terminal array 300 may be disposed on the circuit board 200 .

[0038] The terminal array 300 may be a metal conductive component. When a function card such as a user identification card is inserted into the card holder, the terminal array 300 may serve as a connecting component electrically connecting the card holder and the function card, so that the function card can exchange data with the card holder.

[0039] The housing 100 can provide a mounting position for the circuit board 200 , and the housing 100 can fix the circuit board 200 , the terminals and the inserted function card.

[0040] The circuit board 200 may be bonded to the inner surface of the housing 100 , and the inner surface of the housing 100 may be the side of the housing 100 facing the function card after the function card is inserted into the card socket.

[0041] The disclosure is not limited thereto, and the circuit board 200 may also be fixed to the housing 100 by screws or welding.

[0042] The circuit board 200 can be electrically connected to the terminal array 300, and the terminal array 300 can be electrically connected to electronic components such as ports or processors outside the card holder through the wiring setting of the circuit board 200, so that when the terminal array 300 contacts the function card, the function card can exchange data with the electronic device through the terminal array 300 and the circuit board 200.

[0043] Since the terminal array 300, the circuit board 200 and the housing 100 are independent components, in the structural design of the card holder, the structural modification of the card holder can be achieved at a lower cost by changing the size of the housing 100, the size of the circuit board 200, the position or type of the terminal array 300, etc., so that the card holder can adapt to different electronic equipment stacking design requirements.

[0044] The present disclosure achieves the separation of the terminal array 300 and the shell 100 by directly setting the terminal array 300 on the circuit board 200 and then setting the circuit board 200 on the shell 100 of the card holder, thereby improving the independence of each component of the card holder, making each component relatively independent and variable, reducing the cost of changing the design of the card holder, and facilitating the design change of the card holder for the stacking design of the internal components of the electronic device.

[0045] In some embodiments, Figure 1-4 As shown, the terminal array 300 may include a plurality of terminals.

[0046] The terminal may be a metal conductive component. When the function card is inserted into the card holder, the terminal may serve as a connecting component for electrically connecting the card holder to the function card, so that the function card can exchange data with the card holder.

[0047] There can be multiple terminals, and the number and location of the terminals can be set according to the requirements of the function card and the card holder. For example, the number of terminals can be 6 for data exchange with a user identity card inserted into the card holder.

[0048] A plurality of terminals may be independently disposed on the circuit board 200 , and the terminals may be electrically connected via wiring of the circuit board 200 .

[0049] Illustratively, during the production process, each terminal can be welded onto the circuit board 200 as an independent component, and a plurality of terminals can form a terminal array 300 after being welded onto the circuit board 200 .

[0050] Due to the independence of the multiple terminals, structural connections between different terminals are avoided, so that the terminal arrangement design and the replacement of the terminal design are simpler, thereby reducing the design change cost of the terminal array 300.

[0051] The present disclosure realizes the separation of the terminal array 300 and the housing 100 by directly setting the terminal array 300 on the circuit board 200 and then setting the circuit board 200 on the housing 100 of the card holder. The independence of the terminal array 300, the circuit board 200 and the housing 100 is improved, and the independence of the terminals is improved by setting the terminals on the circuit board 200 independently of each other, thereby improving the independence of each component of the card holder, making each component relatively independent and variable, reducing the cost of card holder design changes, and facilitating the card holder to make design changes for the stacking design of internal components of electronic equipment.

[0052] In some embodiments, Figure 1-4 As shown, the housing may include an upper housing 101 , and the circuit board 200 may include a first circuit board 201 . The first circuit board 201 may be disposed on an inner surface of the upper housing 101 .

[0053] The terminal array may include a first terminal array 301 , and the first terminal array 301 may be disposed on the first circuit board 201 .

[0054] The first terminal array 301 may be a metal conductive component. When a function card such as a user identification card is inserted into the card holder, the terminal array may serve as a connecting component electrically connecting the card holder and the function card, so that the function card can exchange data with the card holder.

[0055] The upper housing 101 can provide a mounting position for the first circuit board 201 , and the upper housing 101 can fix the first circuit board 201 , the first terminal array 301 and the inserted function card.

[0056] The first circuit board 201 may be bonded to the inner surface of the upper housing 101 , and the inner surface of the upper housing 101 may be the side of the upper housing 101 facing the function card after the function card is inserted into the card socket.

[0057] Without limitation, the first circuit board 201 may also be fixed to the upper housing 101 by screws or welding.

[0058] The first circuit board 201 can be electrically connected to the first terminal array 301, and the first terminal array 301 can be electrically connected to electronic components such as ports or processors outside the card holder through the wiring setting of the first circuit board 201, so that when the first terminal array 301 contacts the function card, the function card can exchange data with the electronic device through the first terminal array 301 and the first circuit board 201.

[0059] Since the first terminal array 301, the first circuit board 201 and the upper shell 101 are independent components, in the structural design of the card holder, by changing the size of the upper shell 101, the size of the first circuit board 201, the position or type of the first terminal array 301 and other designs, the structural modification of the card holder can be achieved at a lower cost, so that the card holder can adapt to different electronic equipment stacking design requirements.

[0060] The present disclosure achieves the separation of the first terminal array 301 and the upper shell 101 by directly setting the first terminal array 301 on the first circuit board 201 and then setting the first circuit board 201 on the upper shell 101 of the card holder, thereby improving the independence of various components of the card holder, making each component relatively independent and variable, reducing the cost of design changes of the card holder, and facilitating the design changes of the card holder for the stacking design of internal components of the electronic device.

[0061] In some embodiments, the housing 100 may include a lower housing, which is spaced apart from the upper housing 101 .

[0062] The circuit board 200 may include a second circuit board 202, and the second circuit board 202 may be disposed on the inner surface of the lower housing;

[0063] The terminal array may include a second terminal array 302 , and the second terminal array 302 may be disposed on the second circuit board 202 .

[0064] The second terminal array 302 may be a metal conductive component. When a function card such as a user identification card is inserted into the card holder, the second terminal array 302 may serve as a connecting component electrically connecting the card holder and the function card, so that the function card can exchange data with the card holder.

[0065] When the function card is inserted into the card holder, the upper shell 101 can be located above the function card, and the lower shell can be located below the function card, so that the card holder can realize the recognition and data exchange of the stacked dual-function cards.

[0066] The lower shell can provide a mounting position for the second circuit board 202 , and the upper shell 101 and the lower shell can form a certain clamping effect on the card tray 400 and the function card when the card tray 400 is inserted into the card socket.

[0067] The second circuit board 202 may be bonded to the inner surface of the lower shell, and the inner surface of the lower shell may be the side of the lower shell facing the function card after the function card is inserted into the card socket.

[0068] Without limitation, the second circuit board 202 may also be fixed to the lower housing by screws or welding.

[0069] The second circuit board 202 can be electrically connected to the second terminal array 302, and the second terminal array 302 can be electrically connected to electronic components such as ports or processors outside the card holder through the wiring setting of the second circuit board 202, so that when the second terminal array 302 contacts the function card, the function card can exchange data with the electronic device through the second terminal array 302 and the second circuit board 202.

[0070] Since the first terminal array 301, the first circuit board 201, the upper shell 101, the second terminal array 302, the second circuit board 202 and the lower shell are independent components, in the structural design of the card holder, by changing the size of the shell 100, the size of the circuit board 200, the position or type of the terminal array 300 and other designs, the structural modification of the card holder can be achieved at a lower cost, so that the card holder can adapt to different electronic equipment stacking design requirements.

[0071] The present disclosure achieves the separation of the terminal array 300 from the housing by directly setting the terminal array 300 on the circuit board 200 and then setting the circuit board 200 on the housing of the card holder. Data transmission can be achieved for a stacked dual-function card through the first terminal array 301 and the second terminal array 302. The independence of the terminal array 300, the circuit board 200 and the housing is improved, and the independence of the terminals is improved by setting the terminals on the circuit board 200 independently of each other, thereby improving the independence of each component of the card holder, making each component relatively independent and variable, reducing the cost of the card holder design change, and facilitating the card holder to make design changes for the stacking design of the internal components of the electronic device.

[0072] Figure 5 It is a schematic structural diagram of a terminal array according to an exemplary embodiment.

[0073] In some embodiments, Figure 2 and Figure 5 As shown, the circuit board 200 may include a second circuit board 202, which may be arranged on a side of the middle frame 70 facing the upper shell 101, and the terminal array 300 may include a second terminal array 302, which may be arranged on the second circuit board 202. Exemplarily, the second circuit board 202 may be adhesively connected to the middle frame 70.

[0074] The upper shell 101 can cooperate with the middle frame 70 so that the upper shell 101 and the middle frame 70 can form a certain clamping effect on the card tray 400 and the function card when the card tray 400 is inserted into the card socket.

[0075] By directly setting the second circuit board 202 on the middle frame 70, the overall thickness of the card holder is further saved, the installation space of the card holder is reduced, the position occupied by the card holder in the electronic device is reduced, and the internal stacking design pressure of the electronic device is alleviated.

[0076] Figure 6 It is a schematic structural diagram of a terminal array according to an exemplary embodiment.

[0077] In some embodiments, Figure 6 As shown, the terminal array 300 may include a third terminal array 303 , and the third terminal array 303 may be disposed on the first circuit board 201 .

[0078] The third terminal array 303 may be a metal conductive component. When a function card such as a user identification card is inserted into the card holder, the third terminal array 303 may serve as a connecting component electrically connecting the card holder and the function card, so that the function card can exchange data with the card holder.

[0079] When two function cards laid flat on the card tray 400 are inserted into the card socket, the two function cards can respectively contact the first terminal array 301 and the third terminal array 303 arranged on the first circuit board 201, so that the card socket can realize the recognition and data exchange of the two function cards laid flat on the card tray 400, so that the electronic device can achieve the effect of dual-card dual-standby, providing convenience for users to use electronic devices.

[0080] Figure 7 The figure is a schematic diagram showing the structure of a middle frame according to an exemplary embodiment.

[0081] In some embodiments, Figure 7 As shown, the housing 100 may include a fixing portion 103 , and the housing 100 may be fixed to the middle frame 70 via the fixing portion 103 .

[0082] When the shell 100 is fixed to the middle frame 70, the circuit board 200 arranged on the shell 100 and the terminal array 300 arranged on the circuit board 200 are also fixed relative to the shell 100, which can keep the card seat structure stable, ensure the stable contact between the terminal array 300 and the function card inserted into the card seat, prevent relative displacement between the terminal array 300 and the function card, thereby ensuring the contact effect between the terminal array 300 and the function card, and ensuring the stability of data transmission.

[0083] Exemplarily, the fixing portion 103 may be a screw hole, the middle frame 70 may be provided with a threaded hole, and the fixing portion 103 and the middle frame 70 may be fixed by screws.

[0084] In some embodiments, Figure 5As shown, the fixing parts 103 can be arranged on both sides of the housing 100 , so that the fixing effect received by the housing 100 is uniform, thereby improving the fixing effect of the housing 100 .

[0085] In some embodiments, Figure 1 and 2 As shown, the portion of the shell 100 provided with the circuit board 200 protrudes outward relative to the fixing portion 103. Since the circuit board 200 is provided with a terminal array 300, the terminal array 300 needs to face the function card when the function card is inserted into the card holder. Therefore, by protruding the portion of the shell 100 provided with the circuit board 200 relative to the fixing portion 103, the space for accommodating the card tray 400 and the function card in the card holder can be expanded, thereby making the internal structure of the card holder more compact and reasonable, reducing the installation space of the card holder, and facilitating the development of high-density, high-reliability and miniaturization of electronic equipment.

[0086] In some embodiments, the circuit board 200 is a flexible circuit board.

[0087] The flexible circuit board can be bent and folded freely, so that the circuit board 200 can be arranged according to the changes in the internal space layout of the card holder. And the circuit board 200 can be led out from the inside of the card holder to the outside of the card holder by bending and folding, which improves the laying flexibility of the circuit board 200 and reduces the design difficulty of the circuit board 200.

[0088] In addition, the thickness of the flexible circuit board is relatively low, which can make the internal structure of the card holder more compact and reasonable, reduce the installation space of the card holder, and is conducive to the development of high-density, high-reliability and miniaturization of electronic equipment.

[0089] In some embodiments, the terminal array 300 is configured to perform data transmission with a user identification card or a memory card, thereby expanding the data transmission capabilities of the card holder and meeting different usage requirements of users.

[0090] Exemplarily, when the terminal array 300 includes a first terminal array 301 and a second terminal array 302 , the first terminal array 301 may be used for data transmission with a user identification card, and the second terminal array 302 may be used for data transmission with a memory card.

[0091] Exemplarily, when the terminal array 300 includes the first terminal array 301 and the second terminal array 302 , the first terminal array 301 may be used for data transmission with a user identity card, and the second terminal array 302 may be used for data transmission with a user identity card.

[0092] Exemplarily, when the terminal array 300 includes a first terminal array 301 and a second terminal array 302 , the first terminal array 301 may be used for data transmission with a memory card, and the second terminal array 302 may be used for data transmission with a memory card.

[0093] In some embodiments, the housing 100 is a stamped part. For example, the housing 100 can be a stamped metal part.

[0094] The stamped shell 100 has high production efficiency and does not require high-cost mold replacement. The cost of replacing the shell 100 design is low, which helps reduce the cost of changing the card holder design and is conducive to the card holder making design changes for the stacking design of internal components of the electronic device.

[0095] In some embodiments, Figure 1 As shown, the card holder may further include a push arm 50 and a push rod 60 , and the middle portion of the push arm 50 is hingedly connected to the middle frame 70 , so that the push arm 50 can rotate relative to the middle frame 70 .

[0096] One end of the push arm 50 can abut against the card tray 400, and the other end of the push arm 50 can be connected to the push rod 60. When the push arm 50 rotates, the first end of the push arm 50 can push the card tray 400 out of the card seat along the sliding direction of the card tray 400.

[0097] One end of the push rod 60 may be configured as a push portion 61, and the other end of the push rod 60 may be connected to the other end of the push arm 50. The push portion 61 may be exposed on the surface of the machine body, and the user may push the push rod 60 by pressing the push portion 61, so that the push rod 60 drives the push arm 50 to rotate, and when the push arm 50 rotates, the first end of the push arm 50 may push the card tray 400 that is against the push arm 50 out of the card holder along the sliding direction of the card tray 400.

[0098] By hingedly connecting the middle part of the push arm 50 to the middle frame 70, the push arm 50 and the push rod 60 can be independently arranged with the shell 100, thereby helping to reduce the cost of changing the design of the card holder and facilitating the design change of the card holder for the stacking design of the internal components of the electronic device.

[0099] In some embodiments, the size of the housing 100 can be changed according to stacking design requirements. After being able to accommodate the card tray 400 and the function card required by the design, the size of the housing 100 can be reduced.

[0100] Exemplarily, when the design of the card socket is changed from a dual-card socket to a single-card socket, the area of ​​the circuit board 200 can be reduced from that required to accommodate two sets of terminal arrays 300 to that required to accommodate one set of terminal arrays 300, and the size of the housing 100 can be reduced as the area of ​​the circuit board 200 is reduced.

[0101] This allows the card holder to be compatible with stacked dual cards, flat dual cards, user identification cards, memory cards, etc., simply by changing the design of the housing 100, the circuit board 200 and the terminal array 300.

[0102] Based on the same concept, the embodiment of the present disclosure also provides a middle frame 70 assembly.

[0103] In some embodiments, Figure 7 As shown, the middle frame 70 component may include: a middle frame 70 and a card socket. The shell 100 of the card socket may be fixedly connected to the middle frame 70, which can keep the card socket structure stable, ensure the stable contact between the terminal array 300 and the functional card inserted into the card socket, prevent relative displacement between the terminal array 300 and the functional card, thereby ensuring the contact effect between the terminal array 300 and the functional card, and ensuring the stability of data transmission.

[0104] Based on the same concept, an embodiment of the present disclosure also provides an electronic device.

[0105] The electronic device may be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a message transceiver, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, and a wearable device such as a watch or a bracelet, and may be any electronic device having a card holder. In the following description, a mobile phone is used as an example, but the present disclosure is not limited thereto.

[0106] In some embodiments, the electronic device may include a body, a card socket and a card tray 400. The card socket may be disposed in the body, and the card tray 400 may be slidably disposed in the card socket. The card tray 400 may deliver the function card into the inner cavity of the card socket. The card socket may be used to accommodate the function card and be connected to the function card through the terminal array 300. Exemplarily, the card socket may accommodate a user identification card.

[0107] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.

[0108] It is further understood that the terms "second", "secondary", etc. are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other and do not indicate a specific order or degree of importance. In fact, the expressions "secondary", "secondary", etc. can be used interchangeably.
