Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation application, claiming priority under §365(c), of an International application No. PCT/KR2022/017542, filed on Nov. 09, 2022, which is based on and claims the benefit of a Korean patent application number 10-2021-0153344, filed on Nov. 9, 2021, in the Korean Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     Various embodiments of the disclosure relate to an electronic device, for example, an electronic device in which a storage medium is detachably provided. 
     BACKGROUND ART 
     Typically, an electronic device means a device that performs a specific function according to a program incorporated therein, such as an electronic scheduler, a portable multimedia player, a mobile communication terminal, a tablet personal computer (PC), an image/sound device, a desktop/laptop PC, or a vehicle navigation system, as well as a home appliance. The above-mentioned electronic devices may output, for example, information stored therein as sound or an image. As the integration degree of electronic devices has increased and super-high speed and large-capacity wireless communication has become popular, various functions have recently been provided in a single mobile communication terminal. For example, various functions, such as an entertainment function (e.g., a game function), a multimedia function (e.g., a music/video playback function), a communication and security function for mobile banking, a schedule management function, or an e-wallet function, are integrated in a single electronic device, in addition to a communication function. 
     Among components or additional devices of an electronic device, a memory card (e.g., an SD card) may be useful for storing various document files or multimedia files. A memory card may be useful for expanding a storage capacity in storing, for example, various pieces of information received through the electronic device, generated by a user, or acquired through the electronic device. 
     An electronic device that is personally used by a user, such as a mobile communication terminal, may be provided with a subscriber identification module (SIM) for the purpose of user authentication or security. The subscriber identification module may take a form of a card that is similar to a memory card. For example, the subscriber identification module may be configured with a SIM card. When a storage medium, such as a memory card or a SIM card, is detachably provided, the storage medium may be useful for the expandability of a miniaturized electronic device, such as a mobile communication terminal. 
     DISCLOSURE 
     In making the exterior of a miniaturized electronic device beautiful, a single housing and/or a case structure (e.g., a unibody structure) using a metal material may be utilized. Even in the unibody structure, the housing may be provided with a jack or the like to connect an external device or to connect a connector for wired charging or an earphone. In an electronic device having a unibody structure, a tray structure may be used in detachably providing a storage medium in order to secure an expandability. For example, a tray on which a storage medium (e.g., a memory card or a SIM card) is seated may be inserted from the outside of the housing so as to mount the storage medium to the electronic device. 
     In a structure for detachably mounting a storage medium using a tray, for example, two different types of storage media (a subscriber identification module and a memory card) may be seated on a single tray. When two types of storage media are seated on a tray, it is necessary to provide two seating surfaces on the tray, and there may be a problem in that the thickness of the entire tray is increased with the two types of storage media. According to various embodiments of the disclosure, it is possible to provide an electronic device in which, in a structure for detachably mounting a storage medium by using a tray, the tray has a reduced thickness by integrating two types of storage media into one card. 
     Technical Solution 
     According to various embodiments of the disclosure, it is possible to provide an electronic device including: a housing constituting at least a portion of an exterior of the electronic device; a socket disposed inside the housing; a tray detachably provided in the socket; and a storage medium including a first terminal surface with a terminal and a second terminal surface with a terminal, the first and second terminal surfaces facing away from one another and the storage medium being seatable on the try, and wherein the socket includes a plurality of first conductive contacts that face the first terminal surface and come into contact with at least some of a plurality of pins provided on the storage medium, and a plurality of second conductive contacts that face the second terminal surface and come into contact with at least some of the plurality of pins of the storage medium in a state of being disposed not to come into contact with the plurality of first conductive contacts.

For example, a seating portion  402  for seating the storage medium  300  may be provided on one surface of the base plate  401 . In various embodiments of the disclosure, since only one storage medium  300  is seated on the tray  400 , the seating portion  402  may also be provided on only one surface of the base plate  401  to correspond to the storage medium. The seating portion  402  may have a shape corresponding to the shape of storage medium to be seated thereon. For example, the seating portion  402  may have a shape corresponding to the outer shape of the SIM card or a shape corresponding to the outer shape of the SD card. In addition, through the through hole  403  provided in the base plate  401 , not only one surface (e.g., the first terminal surface  301 ) of the storage medium  300 , but also the other surface (e.g., the second terminal surface  302 ) of the storage medium  300  may be exposed to the outside. Here, the “outside” may refer to the inner space of the socket  500  in the state in which the tray  400  is accommodated in the through hole  403 . For example, when the first terminal surface  301  of the storage medium  300  is seated on the seating portion  402  provided on one surface of the base plate  401 , the second terminal surface  302  of the storage medium  300  may be exposed to the outside as it is in a direction opposite to the first terminal surface  301 , and the first terminal surface  301  of the storage medium  300  may be exposed to the outside through the through hole  403 . When the storage medium  300  is seated on the seating portion  402 , the inner surface defining the seating portion  402  of the base plate  401  may support the edge portions of the storage medium  300  and stably maintain the position of the storage medium  300 . 
     According to various embodiments, the cover member  404  of the tray  400  may facilitate handling of the tray  400  by a user, and the tray  400  may close the tray hole (e.g., the tray hole  209  in  FIG.  2   ) in the state in which the tray  400  is inserted into the housing (e.g., the housing  210  of  FIG.  2   ). For example, the cover member  404  may close the tray hole  209  to reduce the inflow of foreign substances or the like into the housing  210 , while defining a portion of the exterior of the housing  210 . 
     Referring to  FIGS.  8  to  11    together, when the tray  400  is inserted into the housing (e.g., the housing  210  in  FIG.  2   ) in the state in which the storage medium  300  is seated on the tray  400 , at least a portion of the storage medium  300  may be disposed in the inner space of the socket  500 . Similarly to the socket  240  described above with reference to  FIGS.  4  to  6   , the socket  500  of  FIG.  8    may be provided to connect the storage medium  300  to electronic components (e.g., the processor  120  or the communication module  190  in  FIG.  1   ) provided on a circuit board (not illustrated) of the electronic device (e.g., the electronic device  101  in  FIG.  1   ) while providing a space  500  (hereinafter, referred to as a “slot  500   a ”) for accommodating the tray  400 . The socket  500  may include a first plate  501  and a second plate  502  as plates provided to surround at least a portion of the slot  500   a  in which the tray  400  is detachably provided. In the state in which the storage medium  300  is seated, when the tray  400  is inserted into the tray hole (e.g., the tray hole  209  in  FIG.  2   ), at least a portion of the storage medium  300  may be accommodated in the slot  500   a  of the socket  500 . The socket  500  may include a plurality of contacts  503  and  504  to come into contact with a plurality of connection pins (or pads) provided on each of both surfaces (the first terminal surface  301  and the second terminal surface  302 ) of the storage medium  300 . According to an embodiment, the socket may include a plurality of first conductive contacts  503  that face the first terminal surface  301  and come into contact with at least some of the plurality of pins provided on the storage medium  300  and a plurality of second conductive contacts  504  that face the second terminal surface  302  and come into contact with at least some of the plurality of pins of the storage medium  300  in the state of being disposed not to come into contact with the plurality of first conductive contacts  503 . For example, the plurality of first conductive contacts  503  and the plurality of second conductive contacts  504  may be terminals such as pins, pogo pins, and C-clips. 
     Referring to  FIG.  12   , in the case where the tray  400  on which the storage medium  300  is seated is accommodated and mounted in the slot  500   a  of the socket  500 , when the tray  400  enters, the plurality of first conductive contacts  503  may be pressed upward according to the insertion of the storage medium  300 , and the plurality of second conductive contacts  504  may be pressed downward according to the insertion of the storage medium  300 . According to various embodiments, the socket  500  may include a plurality of (1-1) th  conductive contacts  503   a  and a plurality of (1-2) th  conductive contacts  503   b , which are disposed, respectively, at a first portion and a second position, which are separated from each other in the longitudinal direction (e.g., the +Y direction) of the socket, and a plurality of (2-1) th  conductive contacts  504   a  and a plurality of (2-2) th  conductive contacts  504   b , which are disposed at the first position and the second position, respectively. Here, the “first position” may be an inner portion of the slot  500   a , and the “second position” may be an outer portion of the slot  500   a  (the portion which the tray  400  is to enter at the time of being mounted). Accordingly, at the time of first entry of the tray  400 , the plurality of (1-2) th  conductive contacts  503   b  and the plurality of (2-2) th  conductive contacts  504   b  may be pressed first, and then the plurality of (1-1) th  conductive contacts  503   a  and the plurality of (2-1) th  conductive contacts  504   a  may be pressed. When the tray  400  is fully mounted, the plurality of first conductive contacts  503  may come into contact with the first terminal surface  301  of the storage medium  300 , and the plurality of second conductive contacts  504  may come into contact with the second terminal surface  302  of the storage medium  300  through the through hole  403  of the tray  400 . 
     According to various embodiments of the disclosure, a double-sided contact structure may be provided from the viewpoint of the storage medium  300 , but a single-sided contact structure may be provided from the viewpoint of each of cards (e.g., a SIM card and an SD card). According to this, for example, when a SIM card and an SD card are provided, respectively, on one surface and the other surface of the storage medium  300 , user authentication and expansion of storage capacity or function of the electronic device  101  may be implemented by using only one storage medium  300 . For example, only one storage medium  300  may be seated on the tray  400  illustrated in  FIGS.  8  to  12   . The storage medium  300  may have a thickness of t3, and the total height of the tray  400  on which the storage medium  300  is seated may be the sum of the thickness of one storage medium  300  and the thickness of the base plate  401 . The tray  400  on which one storage medium  300  is seated as described above may be configured to have a smaller height than the tray  219  on which two storage media  220  and  230  according to the comparative embodiment described above in  FIGS.  4  to  6    are seated, thereby following the trend of miniaturization and improvement of portability of electronic devices. 
     In the embodiment illustrated in  FIGS.  8  to  12   , for example, when a SIM card is provided on the first terminal surface  301  of the storage medium  300  and an SD card is provided on the second terminal surface  302  of the storage medium  300 , the plurality of (1-1) th  conductive contacts  503   a  and the plurality of (1-2) th  conductive contacts  503   b  may come into contact with metallic terminals (e.g., pins) of the SIM card on the first terminal surface  301 , and the plurality of (2-1) th  conductive contacts  504   a  may come into contact with metallic terminals (e.g., pins) of the SD card of the second terminal surface  302 . Meanwhile, unlike the plurality of (1-1) th  conductive contacts  503   a , the plurality of (1-2) th  conductive contacts  503   b , and the plurality of (2-1) th  conductive contacts  504   a , which come into contact with metallic terminals (e.g., pins), the plurality of (2-2) th  conductive contacts  504   b  may not come into contact with metallic terminals (e.g., pins). The sizes of the tray and the socket may vary depending on the types of storage media seated on the tray, the number of storage media, and an arrangement method when there are a plurality of storage media. In addition, the sizes of a tray and a socket are closely related to the size of an electronic device, and thus may be an important factor in designing the electronic device. The type, number, and arrangement method of storage media may be predetermined in the design stage of the electronic device. When a SIM card is provided on one surface of a storage medium and an SD card is provided on the other surface, factors such as the number and positions of contacts of the socket may be determined in consideration of the arrangement of the storage media. For example, when a SIM card is provided on one surface and an SD card is provided on the other surface, in some comparative embodiments (e.g., the embodiment of  FIG.  6   ), two different positions (the first position and the second position) on the side that is in contact with the SIM card may be provided with contacts, and one position (the first position) that is in contact with the SD card may be provided with a contact. Unlike this, according to various embodiments of the disclosure, even on the side that is in contact with the SD card, each of two positions (the first position and the second position) may be provided with a contact. At this time, a contact positioned in a portion that does not come into contact with the metallic terminals (e.g., pins) of the SD card may be a balance tuning contact (hereinafter, referred to as a “balance contact”) for ensuring the stability of the contact by providing a uniform contact pressure (e.g., the force in the arrow direction in  FIG.  8   ). 
       FIG.  13    is a view illustrating a socket according to various embodiments.  FIG.  14    is a view illustrating a cross section of the socket according to various embodiments, cut in a width direction.  FIG.  15    is a view illustrating a cross section of the socket according to various embodiments, cut in a longitudinal direction. 
     According to various embodiments, the socket  500  may include a plurality of (1-1) th  conductive contacts  503   a  and a plurality of (1-2) th  conductive contacts  503   b , which are disposed, respectively, at a first portion and a second position, which are separated from each other in the longitudinal direction (e.g., the +Y direction) of the socket, and a plurality of (2-1) th  conductive contacts  504   a  and a plurality of (2-2) th  conductive contacts  504   b , which are disposed at the first position and the second position, respectively. Here, a plurality of (1-1) th  conductive contacts  503   a  and a plurality of (2-1) th  conductive contacts  504   a  may be provided at the first position, and a plurality of (1-2) th  conductive contacts  503   b  and a plurality of (2-2) th  conductive contacts  504   b  may be provided at the second position, as illustrated in  FIG.  13   .  FIG.  13    may illustrate, for example, cross sections of the (1-1) th  conductive contacts  503   a  and the (2-1) th  conductive contacts  504   a  at the first position in the width direction (e.g., in the +X direction of  FIG.  14   ). In the embodiment illustrated in  FIG.  13    as well, there may be provided a plurality of (1-1) th  conductive contacts  503   a  and a plurality of (2-1) th  conductive contacts  504   a . Here, the number of contacts is not limited to a specific embodiment and may vary from embodiment to embodiment. 
     According to various embodiments, the first conductive contacts  503  and the second conductive contacts  504  may have an overlapping structure in the height direction (e.g., the +Z direction) of the socket  500  as illustrated in  FIGS.  14  and  15    in order to secure a stable amount of pressing. For example, the plurality of (1-1) th  conductive contacts  503   a  and the plurality of (2-1) th  conductive contacts  504   a  disposed at the first position may at least partially overlap in the height direction by the thickness h thereof (e.g., the +Z direction) of the socket  500 , and the plurality of (1-2) th  conductive contacts  503   b  and the plurality of (2-2) th  conductive contacts  504   b  disposed at the second position may at least partially overlap by the thickness h thereof in the height direction of the socket  500  (e.g., the +Z direction). 
       FIG.  16    is a view illustrating an arrangement relationship between first conductive contacts and second conductive contacts in a cross section of a socket according to various embodiments, cut in a longitudinal direction.  FIG.  17    is a view illustrating an arrangement relationship between first conductive contacts and second conductive contacts in a cross section of a socket according to various embodiments, cut in a longitudinal direction. 
     According to  FIGS.  16  and  17   , the tips P1 of a plurality of (1-1) th  conductive contacts  503   a  and the tips P3 of a plurality of (2-1) th  conductive contacts  504   a  disposed at a first position may be disposed not to interfere with each other in the height direction of the socket  500  (e.g., the +Z direction), and the tips P2 of a plurality of (1-2) th  conductive contacts  503   b  and the tips P4 of a plurality of (2-2) th  conductive contacts  504   b  disposed at a second position may be disposed not to interfere with each other in the height direction of the socket  500  (e.g., the +Z direction). In this case, the tips P1 of the (1-1) th  conductive contacts  503   a  and the tips P3 of the plurality of (2-1) th  conductive contacts  504   a  may be spaced apart from each other by a first distance d1 in the longitudinal direction of the socket  500  (e.g., the +Y direction), and the tips P2 of the (1-2) th  conductive contacts  503   b  and the tips P4 of the plurality of (2-2) th  conductive contacts  504   b  may be spaced apart from each other by a second distance d2 in the longitudinal direction of the socket  500  (e.g., the +Y direction). Here, the first distance d1 and the second distance d2 may be different from or the same as each other. 
     In addition, the tips P1 of the plurality of (1-1) th  conductive contacts  503   a  are disposed at positions corresponding to the inclined portions C3 of the plurality of (2-1) th  conductive contacts  504   a , and the tips P3 of the plurality of (2-1) th  conductive contacts  504   a  may be disposed at positions corresponding to the inclined portions C1 of the plurality of (1-1) th  conductive contacts  503   a . Furthermore, the tips P2 of the plurality of (1-2) th  conductive contacts  503   b  are disposed at positions corresponding to the inclined portions C4 of the plurality of (2-2) th  conductive contacts  504   b , and the tips P4 of the plurality of second conductive contact  504   b  may be disposed at positions corresponding to the inclined portion C2 of the plurality of (1-2) th  conductive contacts  503   b . In order to increase the amount of pressing of the plurality of contacts, the contact arrangement structure illustrated in  FIGS.  16  and  17    may be provided. 
       FIG.  18    is a view illustrating an arrangement relationship between first conductive contacts and second conductive contacts in a cross section of a socket according a comparative embodiment, cut in a longitudinal direction. 
     The socket  240  according to the comparative embodiment may include a (1-1) th  conductive contact  243   a  and a second conductive contact  244  disposed at a first position. In addition, the socket  240  may include a (1-2) th  conductive contact  243   b  at a second position. Referring to  FIG.  18   , the (1-1) th  conductive contact  243   a  and the second conductive contact  244  may not interfere with each other even if the respective tips P5 and P6 thereof are configured to overlap each other in the state of facing each other. However, in such a structure, the size (e.g., thickness) of the tray to be inserted into the slot of the socket  240  can be very large, which may be in opposition to the trend of miniaturization of electronic devices. In contrast to this, according to various embodiments of the disclosure, there is no interference while providing a sufficient amount of pressing when the tray is mounted since the tips at positions corresponding to each other are staggered to each other in the state in which the plurality of conductive contacts overlap each other.
