In response to the recess contact surface  244   a  and the first surface  281   a  in contact with each other, the fastening pin  280  may be no longer moved toward the recess (e.g., the recess  244  of  FIG. 4 ). The second surface  281   b  may be a surface in contact with a contact surface  252   b  of the coupling hole in response to fastening pin  280  separating from the housing  240 . In response to the second surface  281   b  in contact with a coupling hole contact surface (e.g., the coupling hole contact surface  252   b  of  FIG. 9 ), the fastening pin  280  may be no longer moved toward a communication path  255 . Details will be described later. The rounding portion  282  may be formed at both ends from which a coupling body  280   a  extends. The rounding portion  282  may allow the fastening pin  280  to be moved in response to pressurizing air. 
     According to an embodiment of the disclosure, a sealing member  290  may be coupled to the outside of the fastening pin  280 . In response to the fastening pin  280  being arranged in the coupling hole  252 , the sealing member  290  may be compressed in the coupling hole  252 . The sealing member  290  may prevent the fastening pin  280  from moving in a state in which the fastening pin  280  is arranged in the coupling hole  252 . Accordingly, it is possible to prevent the housing  240  and the fastening pin  280  from unexpectedly separating. In addition, the sealing member  290  may seal the space between the fastening pin  280  and the coupling hole  252  to prevent water and/or foreign substances (e.g., dust) from entering the housing  240 . For example, recently, a waterproof function has been required for electronic devices, and the sealing member  290  may prevent water from flowing into the housing  240 . In addition, air may be pressurized in order to couple the fastening pin  280  to the housing  240  and air may be sucked in order to separate the fastening pin  280  from the housing  240 , air may be sucked. Accordingly, the sealing member  290  may act as a seal so as to allow the fastening pin to couple to or separate from the housing  240 . Details will be described later. 
     In addition, the sealing member  290  may include a material having elasticity. For example, the sealing member  290  may include rubber or silicone.

     For example,  FIG. 7  is a view illustrating the cover  250  of  FIG. 3  as viewed from the −Z direction to the +Z direction. 
     Referring to  FIG. 7 , according to an embodiment of the disclosure, the cover  250  may include an air hole  254 . The air hole  254  may be formed in the outer surface  250   b  of the cover  250 . The air hole  254  may move the fastening pin (e.g., the fastening pin  280  of  FIG. 6 ) through a pressurizer (e.g., a pressurizer  300  of  FIG. 10 ) to be described later, so as to allow the fastening pin  280  to couple to and separate from the housing  240  and the fastening pin  280 . For example, air may move the fastening pin  280  through the air hole  254  and a communication path (e.g., the communication path  255  of  FIG. 9 ). Because the housing  240  and the cover  250  are coupled to each other in a simple manner, the productivity of the electronic device may be increased. In addition, a position at which a coupling protrusion (e.g., the coupling protrusion  251  in  FIG. 5 ) is formed is not limited and a structure for reinforcing the strength of the outer surface  250   b  of the cover is not required. Accordingly, the outer surface  250   b  of the cover may be formed in a smooth shape without the protrusion. Further, in response to the fastening pin  280  coupling to the housing  240 , the fastening pin  280  may not be seen through the air hole  254 . Accordingly, a producer and/or a user can recognize that the fastening pin  280  is coupled to the housing  240 , and the appearance of the cover  250  may be improved. Details will be described later. 
     According to an embodiment of the disclosure, the cover  250  may include a back glass mounting portion  250   c .

Accordingly, the sealing member  290  may be stably coupled to the fastening pin  280 . According to an embodiment of the disclosure, the sealing member  290  may seal the space between the inner wall  252   a  forming the coupling hole  252  and the fastening pin  280 . The sealing member  290  may prevent the fastening pin  280  from moving in the state in which the fastening pin  280  is arranged in the coupling hole  252 . Accordingly, the fastening pin can be prevented from unexpectedly separating from the housing  240 . In addition, the sealing member  290  may seal the space between the fastening pin  280  and the coupling hole  252  to prevent water from flowing into the housing  240 . For example, recently, a waterproof function has been required for electronic devices, and thus the sealing member  290  may prevent water from flowing into the housing  240 . The sealing groove  283  may be formed to correspond to the number and shape of the sealing members  290 . 
     According to an embodiment of the disclosure, the coupling protrusion  251  may be arranged between the plurality of fixing ribs  243 .

For example, a portion of the coupling body may be accommodated in the accommodating space  252   c . In addition, the other portion of the fastening pin  280  may be accommodated in the recess  244 . For example, the other portion of the coupling body may be accommodated in the accommodating portion  244   c . Accordingly, the fastening pin  280  may be coupled to the housing  240 , and the cover  250  may be coupled to the housing  240 . 
     According to an embodiment of the disclosure, in response to fastening pin  280  coupling to the housing  240 , the first surface  281   a  may be in contact with the recess contact surface  244   a . The fastening pin  280  may be no longer moved to the side out of the coupling hole  252 , a portion of the coupling body may be accommodated in the accommodating space  252   c , and the other portion thereof may be accommodated in the recess  244 . Accordingly, cover  250  may be coupled to the housing  240 . In addition, the plurality of constraining surfaces  244   b  may be provided in each of the Z direction and the −Z direction of the fastening pin  280  to restrict the Z direction movement of the fastening pin  280 . Accordingly, in the state in which the fastening pin  280  is coupled to the housing  240 , the fastening pin  280  may not be separated in the Z direction. Even when the fastening pin  280  is shaken in the coupling hole  252  due to an unexpected external force, the housing  240  and the fastening pin  280  may be stably coupled due to the plurality of constraining surfaces  244   b . The position of the fastening pin  280  coupled to the housing  240  may be referred to as a first position. 
       FIGS. 10 to 12  are cross-sectional views illustrating a process in which the fastening pin is coupled to the housing in the electronic device according to one of the various embodiments of the disclosure.  FIG. 13  is a flowchart illustrating the process in which the fastening pin is coupled to the housing in the electronic device according to one of the various embodiments of the disclosure. 
     Referring to  FIGS. 10 to 13 , according to an embodiment of the disclosure, the pressurizer  300  may be arranged on the outer surface  250   b  of the cover  250 . In addition, the cover  250  may include the communication path  255  connected to the air hole  254  and the coupling hole  252 , respectively. The communication path  255  may be connected at one end of the coupling hole  252 . For example, the air hole  254  may be an inlet and/or an outlet of the communication path  255 . The communication path  255  may be connected to a region adjacent to the coupling hole contact surface  252   b  to allow air to flow through the coupling hole  252 . The pressurizer  300  may inject air into the air hole  254  to move the fastening pin  280  toward the recess  244  side. 
     According to various embodiments of the present disclosure, as for an assembling method (e.g., a manufacturing method of the electronic device  200 ) of an electronic device (e.g., the electronic device  200  of  FIG. 2 ), the housing  240  is arranged, the display  210  is coupled to one side of the housing  240 , the cover  250 , in which the coupling pin  280  is accommodated, is arranged at the other side of the housing  240 , and the coupling pin is coupled to the housing  240 . Accordingly, the electronic device  200  may be assembled. However, the order, in which the housing  240 , the display  210 , or the cover  250  are arranged, may be changed. 
     Hereinafter a process in which the housing  240  and the fastening pin  280  are coupled will be described with reference to  FIG. 13 . According to an embodiment of the disclosure, the pressurizer  300  may inject air into the air hole  254  ( 1310 ). Air injected into the air hole  254  may flow to the fastening pin  280  through the communication path  255 . The air flowing toward the fastening pin  280  may press the rounding portion  282  and the sealing member  290  mounted on the fastening pin  280 . Because air flows from the coupling hole  252  toward the recess  244  side, the fastening pin  280  and the sealing member  290  may be also moved toward the recess  244  side ( 1320 ). In this case, the sealing member  290  may seal the space between the inner wall  252   a  forming the coupling hole  252  and the coupling body  280   a . Therefore, the air may not be discharged into the space between the inner wall  252   a  and the fastening pin  280  and may press the sealing member  290  to move the fastening pin  280  and the sealing member  290 . As illustrated in  FIG. 11 , a space may be formed between the coupling hole contact surface  252   b  and the second surface  281   b  as the fastening pin  280  and the sealing member  290  are moved toward the recess  244  side. As illustrated in  FIG. 12 , the first surface  281   a  may come into contact with the recess contact surface  244   a , thereby stopping the movement of the fastening pin  280  ( 1330 ). In this case, it can be seen that the housing  240  and the fastening pin  280  are coupled, and the housing  240  and the cover  250  are coupled. In response to the completion of the coupling of the housing  240  and the cover  250 , it is possible to stop the injection of air into the air hole  254  through the pressurizer  300  ( 1340 ). 
       FIG. 14  is a perspective view illustrating a state in which the housing and the fastening pin are separated from each other in the electronic device according to one of the various embodiments of the disclosure.  FIG. 15  is a cross-sectional view illustrating a state in which the housing and the fastening pin are separated from each other in the electronic device according to one of the various embodiments of the disclosure. 
     Referring to  FIGS. 14 and 15 , according to an embodiment of the disclosure, in response to the fastening pin separating from the housing  240 , the coupling hole contact surface  252   b  may be in contact with the second surface  281   b . For example, the coupling hole contact surface  252   b  may be in contact with the second surface  281   b . The accommodating space  252   c  may be provided to accommodate the fastening pin  280 . The fastening pin  280  may be moved toward the communication path  255 . The entire coupling body  280   a  may be accommodated in the accommodating space  252   c . For example, the fastening pin  280  may not be accommodated in the accommodating portion  244   c  of the recess, but may be accommodated only in the coupling hole  252 . Accordingly, the recess contact surface  244   a  may not be in contact with the plurality of constraining surfaces  244   b  and the housing  240  may be separated from the cover  250 . The position of the fastening pin  280  separated from the housing  240  may be referred to as a second position. 
       FIGS. 16 to 18  are cross-sectional views illustrating a process in which the fastening pin is coupled to the housing in the electronic device according to one of the various embodiments of the disclosure.  FIG. 19  is a flowchart illustrating the process in which the housing and the fastening pin are separated from each other in the electronic device according to one of the various embodiments of the disclosure. 
     Referring to  FIGS. 16 to 19 , according to an embodiment of the disclosure, the pressurizer  300  may be arranged on the outer surface  250   b  of the cover  250 . The pressurizer  300  may suck air through the air hole  254  and the communication path  255  to allow the fastening pin  280  to be moved toward the accommodating space  252   c  side. 
     Hereinafter a process in which the housing  240  and the fastening pin  280  are separated from each other will be described with reference to  FIG. 19 . According to an embodiment of the disclosure, the pressurizer  300  may suck air through the air hole  254  ( 1910 ). In response to sucking air through the air hole  254 , air present in the communication path  255  and the accommodating space  252   c  may also be sucked. Air is sucked into the communication path  255  and the air hole  254  through the pressurizer  300 , and the sealing member seals the space between the fastening pin  280  and the inner wall  252   a  to prevent air from leaking. Accordingly, a difference in air pressure may occur between the accommodating space  252   c  and recess  244 . For example, the accommodating space  252   c  connected to the communication path  255  may have a lower pressure than the accommodating portion  244   c . According to the pressure difference, the fastening pin  280  may be pressed toward the accommodating space  252   c  side connected to the communication path  255 . Accordingly, the fastening pin  280  may be moved toward the accommodating space  252   c  side connected to the communication path  255  ( 1920 ). In this case, the sealing member may seal the space between the inner wall  252   a  forming the coupling hole  252  and the coupling body  280   a . Therefore, the air may not be discharged into the space between the inner wall  252   a  and the fastening pin  280 , and thus the fastening pin  280  and the sealing member may be moved by the difference in air pressure. As illustrated in  FIG. 17 , a space may be formed between the recess contact surface  244   a  and the first surface  281   a  as the fastening pin  280  and the sealing member are moved toward the accommodating space  252   c  side. As illustrated in  FIG. 18 , the second surface  281   b  may be in contact with the fastening pin contact surface  281  and thus the movement of the fastening pin  280  may be stopped ( 1930 ). In this case, it can be seen that the housing  240  and the fastening pin  280  are separated from each other, and the housing  240  and the cover  250  are separated from each other. In response to the completion of the separation of the housing  240  and the cover  250 , it is possible to stop the suction of the air through the pressurizer  300  ( 1940 ). 
       FIG. 20  is a plan view illustrating a portion C in which a state in which the fastening pin is coupled to the housing in the electronic device according to one of the various embodiments of the disclosure.  FIG. 21  is a plan view illustrating a portion C in which a state in which the housing and the fastening pin are separated from each other in the electronic device according to one of the various embodiments of the disclosure. 
     Referring to  FIG. 20 , according to an embodiment of the disclosure, in response to the completion of the coupling of the housing  240  and the fastening pin  280 , the fastening pin  280  may not be seen through the air hole  254 . For example, the fastening pin  280  may be coupled to the recess contact surface  244   a . The accommodating space  252   c  may be formed in a region adjacent to the coupling hole contact surface  252   b  (refer to  FIG. 9 ). In this case, the accommodating space  252   c  may be a separation space  252   c  in which the coupling hole contact surface  252   b  and the fastening pin  280  are spaced apart. An area of the separation space  252   c , an area of the communication path  255 , and an area of the air hole  254  may be the same or similar. As a result, the fastening pin  280  may be positioned in the coupling hole  252  so as not to be seen through the air hole  254  formed on the outer surface  250   b . Accordingly, the producer and/or the user can recognize that the fastening pin  280  is coupled to the housing  240 . 
     Referring to  FIG. 21 , according to an embodiment of the disclosure, in response to the fastening pin  380  separated from the housing  240 , the fastening pin  280  may be seen through the air hole  254 . For example, the fastening pin  280  may be coupled to the fastening hole contact surface  252   b . As a result, the fastening pin  280  may be positioned in the coupling hole  252  to be seen through the air hole  254  formed in the outer surface  250   b . Accordingly, the producer and/or the user can confirm that the housing  240  and the fastening pin  280  are separated from each other.

     Referring to  FIG. 22 , according to another embodiment of the disclosure, a fastening pin  280  and a sealing member  291  may be formed by insert injection. For example, it is possible to form the fastening pin  280  and the sealing member  291  at once by insert injection without separately assembling the fastening pin  280  and the sealing member  291 . 
     Referring to  FIGS. 23 and 24 , according to another embodiment of the disclosure, a fastening pin  280  and sealing members  292  and  293  may be formed by insert injection. For example, the sealing member  292  may be injected into entire outer surface  284  of the fastening pin  280 . The sealing member  293  may be injected in such a way that only a portion of the outer surface  284  of the fastening pin is exposed. This may be effective when the fastening pin  280  is insulated from other components. For example, when the housing  240 , the cover  250 , and the fastening pin  280  are all formed of metal, components inside the housing  240  may be damaged due to an unexpected overcurrent. In this case, the sealing members  292  and  293  may insulate between the components.

     Referring to  FIGS. 26 and 27 , according to still another embodiment of the disclosure, a fastening pin  280  may include a tapered portion  282   a  and an edge portion  282   b . The tapered portion  282   a  and the edge portion  282   b  may be formed at both ends from which the coupling body  280   a  extends. The tapered portion  282   a  may allow the fastening pin  280  to be moved in response to pressurizing air. 
       FIG. 28  is a perspective view illustrating a state in which a fastening pin is coupled to a housing in an electronic device according to still another of the various embodiments of the disclosure. 
     Referring to  FIG. 28 , according to still another embodiment of the disclosure, a sealing member  294  may be attached to an inner wall  252   a  of a coupling protrusion  251 . The sealing member  294  may be attached to the inner wall  252   a  of the coupling protrusion  251  to seal a space between a fastening pin  280  and the inner wall  252   a . The sealing member  294  may prevent the fastening pin  280  from moving in a state in which the fastening pin  280  is arranged in the coupling hole  252 . In addition, the sealing member  294  may seal the space between the fastening pin  280  and the coupling hole  252  to prevent water from flowing into the housing  240 . In addition, air may be pressurized in order to couple the fastening pin  280  to the housing  240  and air may be sucked in order to separate the fastening pin  280  form the housing  240 . Accordingly, the sealing member  294  may act as a seal so as to allow the housing  240  and the fastening pin  280  to be coupled to each other or to be separated from each other. 
       FIG. 29  is a perspective view illustrating a state in which a housing and a fastening pin are separated from each other an electronic device according to still another of the various embodiments of the disclosure.

     In the state in which the fastening pin  280  is coupled to the housing  240 , the compression of the at least one sealing member  290  may be released. That is, in the state in which the fastening pin  280  is coupled to the housing  240 , the at least one sealing member  290  may be returned to its original state. In a state in which the fastening pin  280  and the housing  240  are coupled, the sealing member  290  may be caught by the separation prevention portion  256 . The separation prevention portion  256  may prevent the fastening pin  280 , to which the sealing member  290  is coupled, from moving toward the coupling hole contact surface  252   b  side. The separation prevention portion  256  may prevent the coupling pin  280 , to which the sealing member  290  is coupled, from separating from the housing  240 . Accordingly, the separation prevention portion  256  may increase a coupling force between the fastening pin  280  and the housing  240 . 
       FIG. 31  is a view illustrating a fastening pin and a sealing member in an electronic device according to still another of the various embodiments of the disclosure. 
     Referring to  FIG. 31 , according to still another embodiment of the disclosure, a fastening pin  280  may include a sealing groove  283  into which a sealing member  290  is inserted. The sealing groove  283  may include a first sealing groove  283   a  and a second sealing groove  283   b . The first sealing groove  283   a  and the second sealing groove  283   b  may be formed to have different depths. For example, the first sealing groove  283   a  may be formed to have a depth less than that of the second sealing groove  283   b . As described above, a sealing member  290  may be compressed upon being arranged in a coupling hole  252   b . A sealing member  290   a  inserted into the first sealing groove  283   a  may be a first sealing member  290   a . A sealing member  290   b  inserted into the second sealing groove  283   b  may be the second sealing member  290   b . The first sealing member  290   a  may be compressed more than the second sealing member  290   b . In response to the fastening pin  280  coupled to the housing  240 , the first sealing member  290   a  may be more caught by the separation prevention portion  256 . It is possible to further prevent the coupling pin  280 , to which the sealing member  290  is coupled, from moving toward the coupling hole contact surface  252   b  side.

As described above, the sealing member  290  may be compressed upon being arranged in the coupling hole  252   b . Because the diameter of the first sealing member  295   a  is greater than that of the second sealing member  295   b , the first sealing member  295   a  may be compressed more than the second sealing member  295   b . In response to the fastening pin  280  coupled to the housing  240 , the first sealing member  295   a  may be more caught by the separation prevention portion  256 . It is possible to further prevent the coupling pin  280 , to which the sealing member  295  is coupled, from moving toward the coupling hole contact surface  252   b  side. Accordingly, the coupling force between the fastening pin  280  and the housing  240  may be increased. 
     In the drawing, two sealing members  295  are shown, but the disclosure is not limited thereto. Alternatively, a single sealing member  295  may be provided, or three or more sealing members  295  may be provided.
