     With reference to  FIG.  1 A  to  FIG.  1 C , the electronic device  100  with the detachable plug of the disclosure includes a main body  110  and a plug body  120 . 
     With reference of  FIG.  1 D  and  FIG.  1 F  together, the main body  110  has a fitting recess FR, a first conductive terminal group  111 , and a press portion  112 . The fitting recess FR is formed on a side of the main body  110 , and the first conductive terminal group  111  is disposed in the fitting recess FR. The press portion  112  is located on at least one side of the fitting recess FR, and the press portion  112  is formed by at least one exterior side plate P 1  and at least one interior side plate P 2  of the main body  110  together. In this embodiment, the press portion  112  is located on two sides of the fitting recess FR, and the press portion  112  is formed by two exterior side plates P 1  and two interior side plates P 2  of the main body  110  together. In detail, the main body  110  is formed with the exterior side plates P 1  and the interior side plates P 2  separated from each other in a casing portion on the sides of the fitting recess FR, where each of the exterior side plates P 1  and the corresponding interior side plate P 2  may be disposed in parallel and maintain a distance, such that a press space PS exists between each of the exterior side plates P 1  and the corresponding interior side plate P 2  to form the press portion  112 . In this embodiment, each of the interior side plates P 2  has an opening OP communicating with the fitting recess FR, and each of the exterior side plates P 1  has a bump BP passing through the corresponding opening OP. With reference to  FIG.  1 E  together, after pressed by an external force F, each of the exterior side plates P 1  is bent and approaches the corresponding interior side plate P 2 , such that each of the bumps BP passes through the corresponding opening OP and enters the fitting recess FR, and two press spaces PS are reduced at the same time. Operation relation between the press portion  112  and the plug body  120  is further described in the following paragraphs. 
     The plug body  120  is detachably configured in the fitting recess FR of the main body  110 , where a width of the fitting recess FR is substantially equal to a width of the plug body  120  to facilitate the alignment and fixing of the plug body  120 . The plug body  120  has a power pin group  121  and a second conductive terminal group  122  (illustrated in the cross-sectional view of  FIG.  1 D ). The power pin group  121  protrudes from a top surface TS of the plug body  120 , and the power pin group  121  may be used to be connected to a mains socket. The second conductive terminal group  122  is configured in the plug body  120  and is electrically coupled to the power pin group  121 . With reference to  FIG.  1 A  and  FIG.  1 D , the first conductive terminal group  111  is adapted to pass through the plug body  120  and be coupled with the second conductive terminal group  122  to accommodate the plug body  120  in the fitting recess FR. Thus, the plug body  120  and the main body  110  are integrally connected, such that the first conductive terminal group  111  is electrically coupled with the power pin group  121  through the second conductive terminal group  122 . In some embodiments, each power pin in the power pin group  121  and the corresponding conductive terminal in the second conductive terminal group  122  may be independent from each other. In some embodiments, each power pin in the power pin group  121  and the corresponding conductive terminal in the second conductive terminal group  122  may be integrally formed. 
     In this embodiment, the second conductive terminal group  122  is made of an elastic material. When the first conductive terminal group  111  passes through the second conductive terminal group  122 , the second conductive terminal group  122  undergoes elastic deformation to clamp the first conductive terminal group  111  to improve electrical connection reliability. 
     With reference to  FIG.  1 G  and  FIG.  1 H , the plug body  120  is disposed with at least one elastic arm  123  corresponding to the press portion  112 . In this embodiment, the plug body  120  has two elastic arms  123 . An end of each of the elastic arms  123  is connected to an exterior wall surface S 1  of the plug body  120 , and a deformation space DS exists between each of the elastic arms  123  and the corresponding exterior wall surface S 1 . The elastic arm  123  is adapted to undergo elastic deformation in the deformation space DS. In this embodiment, the plug body  120  is disposed with a protruding portion  124  at a respective edge of two exterior wall surfaces S 1 . A front edge E of each of the elastic arms  123  is near the corresponding protruding portion  124 , and a distance D exists between each of the elastic arms  123  and the corresponding protruding portion  124 . 
     With reference to  FIG.  1 D ,  FIG.  1 G , and  FIG.  1 H , each of the elastic arms  123  is further disposed with an elastic portion  1231 , an abutting portion  1232 , and a positioning block  1233 . The elastic portion  1231  extends obliquely outward from the corresponding exterior wall surface S 1 . The abutting portion  1232  is formed at an end of the elastic portion  1231  away from the exterior wall surface S 1  and parallel to the exterior wall surface S 1 . The positioning block  1233  is formed at the abutting portion  1232 . When the plug body  120  is accommodated in the fitting recess FR, each of the positioning blocks  1233  is engaged in the corresponding opening OP and abuts against the corresponding bump BP. In addition, each of the abutting portions  1232  partially abuts the corresponding interior side plate P 2 , and each of the protruding portions  124  abuts against the edge of the corresponding interior side plate P 2 . With the positioning block  1233  of the plug body  120  engaged into the opening OP of the main body  110 , the plug body  120  may be avoided from accidentally sliding out of the fitting recess FR during operation. 
     With reference to  FIG.  1 D ,  FIG.  1 G , and  FIG.  1 H , each of the positioning blocks  1233  has an inclined surface IS. The inclined surface IS is obliquely formed at the abutting portion  1232  and is located on a side near the elastic portion  1231 . In other words, the inclined surface IS is located on a side of the positioning block  1233  away from the protruding portion  124 . While the plug body  120  is entering the fitting recess FR, each of the interior side plates P 2  pushes each of the positioning blocks  1233  along the inclined surface IS to cause each of the elastic portions  1231  to be bent. At this time, each of the positioning blocks  1233  is adapted to enter the fitting recess FR along the corresponding interior side plate P 2  until positioned into the opening OP. With the inclined surface IS, each of the positioning blocks  1233  and the corresponding interior side panel P 2  do not block each other during insertion of the plug body  120 . In addition, after the positioning block  1233  is positioned into the opening OP, the positioning block  1233  is no longer pushed by the interior side plate P 2 , such that the elastic deformation of the elastic portion  1231  may be restored to avoid elastic fatigue of the elastic arm  123  due to long-term use, which may thereby prolong the service life. 
     With reference to  FIG.  1 E , each of the exterior side plates P 1  is adapted to be subject to the force F and approach the corresponding interior side plate P 2 , such that each of the bumps BP enters the fitting recess FR through the opening OP and pushes the corresponding positioning block  1233  away from the opening OP. At the same time, the elastic portion  1231  undergoes elastic deformation, such that each of the elastic arms  123  approaches the corresponding exterior wall surface S 1 . In this situation, the plug body  120  is adapted to slide along a horizontal direction PD to be separated from the fitting recess FR of the main body  110 . In this embodiment, the horizontal direction PD may be parallel to the top surface TS of the plug body  120 . 
     With reference to  FIG.  1 B ,  FIG.  1 C , and  FIG.  1 G , the main body  110  has two sliding rails SR, respectively configured on two interior side plates P 2 . The plug body  120  has two sliding grooves SG, respectively configured on two exterior wall surfaces S 1  of the plug body  120 . The two sliding grooves SG slidably accommodate the two sliding rails SR, respectively. With the limiting relation between the sliding rail SR and the sliding groove SG, the plug body  120  is accommodated in or is separated from the fitting recess FR of the main body  110  along the horizontal direction PD. 
     With reference to  FIG.  1 B ,  FIG.  1 C , and  FIG.  1 D , the main body  110  has a limiting block  113 , configured in the fitting recess FR and located among the first conductive terminal group  111  (such as located between two conductive terminals), and a limiting groove  125  is formed on a side of the plug body  120  facing the first conductive terminal group  111 . When the plug body  120  is accommodated in the fitting recess FR, the limiting block  113  of the main body  110  is fixed into the limiting groove  125  of the plug body  120 , and the plug body  120  is thereby positioned in the fitting recess FR more firmly. 
     In short, with reference to  FIG.  1 A  and  FIG.  1 B , the plug body  120  of the disclosure is adapted to enter the fitting recess FR of the main body  110  along the horizontal direction PD, and the two elastic arms  123  of the plug body  120  are respectively fixed to the two interior side plates P 2  of the press portion  112  to engage the plug body  120  into the main body  110 . With reference to  FIG.  1 D  and  FIG.  1 E , when the plug body  120  is disassembled, the external force F is exerted on the two exterior side plates P 1  of the press portion  112 , such that the two exterior side plates P 1  undergo elastic deformation and push the two elastic arms  123  to be separated from the two interior side plates P 2 , and the plug body  120  is thereby not engaged into the main body  110  to achieve the purpose of disassembling the plug body  120 . Since the structure for engaging and separating is designed at an interior junction of the main body  110  and the plug body  120 , rather than outside of the main body of the device, this hidden structure may improve product appearance and reduce water ingress. 
       FIG.  2 A  is a schematic perspective view of an electronic device with a detachable plug according to another embodiment of the disclosure.  FIG.  2 B  is a schematic partial exploded view of the electronic device with the detachable plug of  FIG.  2 A .  FIG.  2 C  is a schematic bottom view of a plug body of  FIG.  2 A .  FIG.  2 D  is a schematic partial cross-sectional view of the electronic device with a detachable plug of  FIG.  2 A  along a section line B-B′.  FIG.  2 E  is a schematic view of a press action of the electronic device with the detachable plug of  FIG.  2 D . 
     With reference to  FIG.  2 A  and  FIG.  2 B , an electronic device  100 A with a detachable plug of another embodiment of the disclosure is different from the electronic device  100  with the detachable plug of  FIG.  1 A . The difference between the two lies in that, with reference to  FIG.  2 B  and  FIG.  2 D , a main body  110   a  has at least one fixing block  113   a . In this embodiment, the main body  110   a  has two fixing blocks  113   a , respectively configured on two inner side plates P 2  and respectively near the corresponding opening OP. With reference to  FIG.  2 C  and  FIG.  2 D , a plug body  120   a  is disposed with a protruding portion  124   a  at a respective edge of the two exterior wall surfaces S 1 . A front edge E of each of elastic arms  123   a  is near the corresponding protruding portion  124   a , and a distance D exists between each of the elastic arms  123  and the corresponding protruding portion  124 . Each of the distances D forms a fixing space FS. Each of the fixing spaces FS communicates with the corresponding deformation space DS. When the plug body  120   a  is accommodated in the fitting recess FR of the main body  110   a , each of the fixing blocks  113   a  is engaged into the corresponding fixing space FS and abuts against the front edge E of the corresponding elastic arm  123   a , and each of the protruding portions  124   a  abuts against the edge of the corresponding interior side plate P 2 . With the fixing block  113   a  of the main body  110   a  engaged into the fixing space FS of the plug body  120   a , the plug body  120   a  may be avoided from accidentally sliding out of the fitting recess FR during operation. 
     Furthermore, with reference to  FIG.  2 C  and  FIG.  2 D , each of the elastic arms  123   a  is disposed with an elastic portion  1231   a  and an abutting portion  1232   a . The elastic portion  1231   a  extends obliquely outward from the corresponding exterior wall surface S 1 . The abutting portion  1232   a  is formed at an end of the elastic portion  1231   a  away from the exterior wall surface S 1  and parallel to the exterior wall surface S 1 . When the plug body  120   a  is accommodated in the fitting recess FR, each of the abutting portions  1232   a  is aligned to the corresponding opening OP and abuts against the corresponding bump BP. 
     With reference to  FIG.  2 D  and  FIG.  2 E , each of the exterior side plates P 1  is adapted to be subject to the force F and approach the corresponding interior side plate P 2 , such that each of the bumps BP enters the fitting recess FR through the opening OP, pushes the corresponding elastic arm  123   a  toward the corresponding exterior wall surface S 1 , and causes the front edge E of each of the elastic arms  123   a  to be separated from the corresponding fixing block  113   a . In this situation, the plug body  120   a  is adapted to slide along a horizontal direction PD to be separated from the fitting recess FR of the main body  110   a.    
       FIG.  3 A  is a schematic perspective view of an electronic device with a detachable plug according to another embodiment of the disclosure.  FIG.  3 B  is a schematic exploded view of the electronic device with the detachable plug in  FIG.  3 A .  FIG.  3 C  is a schematic partial cross-sectional view of the electronic device with the detachable plug of  FIG.  3 A  taken along a section line C-C′.  FIG.  3 D  is a schematic view of a press action of the electronic device with the detachable plug of  FIG.  3 C . 
     With reference to  FIG.  3 A  to  FIG.  3 C , an electronic device  100 B with a detachable plug of another embodiment of the disclosure is different from the electronic device  100  with the detachable plug of  FIG.  1 A . The difference between the two lies in that the electronic device with the detachable plug of the disclosure includes a main body  110   b  and a plug body  120   b , wherein the main body  110   b  includes a plug assembly  111   b  and a casing  112   b . The plug assembly  111   b  has a fitting recess FR and a first conductive terminal group  113   b . The first conductive terminal group  113   b  is disposed in the fitting recess FR. The casing  112   b  has a hole H. The plug assembly  111   b  is configured in the hole H and is combined with the casing  112   b.    
     With reference to  FIG.  3 B  and  FIG.  3 C , at least one first side plate P 3  of the plug assembly  111   b  has an opening OP communicating with the fitting recess FR, and at least one second side plate P 4  of the casing  112   b  has a bump BP. In this embodiment, two first side plates P 3  of the plug assembly  111   b  respectively have the opening OP communicating with the fitting recess FR, and two second side plates P 4  of the casing  112   b  respectively have the bump BP. When the plug assembly  111   b  is combined with the casing  112   b , each of the bumps BP passes through the corresponding opening OP. In this embodiment, the press portion  112  is located on two sides of the fitting recess FR, and the press portion  112  is formed by two first side plates P 3  and two second side plates P 4  together. In detail, each of the first side plates P 3  and the corresponding second side plate P 4  may be disposed in parallel, and each of the first side plates P 3  and the corresponding second side plate P 4  are separated from each other by a distance on the side of the fitting recess FR, such that the press space PS exists between each of the first side plates P 3  and the corresponding second side plate P 4  to form the press portion  112 . 
     Furthermore, with reference to  FIG.  3 B , the plug assembly  111   b  has multiple buckling grooves  1111   b , configured on two first side plates P 3 . The casing  112   b  has multiple buckling members  1121   b , configured on two second side plates P 4 . When the plug assembly  111   b  is combined with the casing  112   b , each of the buckling members  1121   b  is engaged with the corresponding buckling groove  1111   b . In short, the main difference between this embodiment and the embodiment shown in  FIG.  1 A  lies in that the main body  110   b  of this embodiment includes the plug assembly  111   b  and the casing  112   b  engaged and combined with each other, while the portion corresponding to the casing  112  of the main body  110  of the embodiment shown in  FIG.  1 A  may be one single component or be integrally formed. 
     With reference to  FIG.  3 A  to  FIG.  3 C , the plug body  120   b  is detachably configured in the fitting recess FR of the plug assembly  111   b , where a width of the fitting recess FR is substantially equal to a width of the plug body  120   b  to facilitate the alignment and fixing of the plug body  120   b . The plug body  120   b  has a power pin group  121   b  and a second conductive terminal group  122   b  (illustrated in the cross-sectional view of  FIG.  3 C ). The power pin group  121   b  protrudes from a top surface TS of the plug body  120   b , and the power pin group  121   b  may be used to be connected to a mains socket. The second conductive terminal group  122   b  is configured in the plug body  120   b  and is electrically coupled to the power pin group  121   b.    
     With reference to  FIG.  3 C  and  FIG.  3 D , the plug body  120   b  is disposed with at least one elastic arm  123   b . In this embodiment, the plug body  120   b  has two elastic arms  123   b . An end of each of the elastic arms  123   b  is connected to an exterior wall surface S 2  of the plug body  120   b , and a deformation space DS exists between each of the elastic arms  123   b  and the corresponding exterior wall surface S 2 . Each of the elastic arms  123   b  is adapted to undergo elastic deformation in the deformation space DS. 
     Furthermore, each of the elastic arms  123   b  is disposed with an elastic portion  1231   b , an abutting portion  1232   b , and a positioning block  1233   b . The elastic portion  1231   b  extends obliquely outward from the corresponding exterior wall surface S 2 .

The positioning block  1233   b  is formed at the abutting portion  1232   b . When the plug body  120   b  is accommodated in the fitting recess FR, each of the positioning blocks  1233   b  is engaged in the corresponding opening OP and abuts against the corresponding bump BP, and each of the abutting portions  1232   b  partially abuts the corresponding first side plate P 3 . 
     With reference to  FIG.  3 B  and  FIG.  3 C , each of the positioning blocks  1233   b  has an inclined surface IS. The inclined surface IS is obliquely formed at the abutting portion  1232   b  and is located on a side near the elastic portion  1231   b . While the plug body  120   b  is entering the fitting recess FR, each of the first side plates P 3  pushes each of the positioning blocks  1233   b  along the inclined surface IS to cause each of the elastic portions  1231   b  to be bent. At this time, each of the positioning blocks  1233   b  is adapted to enter the fitting recess FR along the corresponding first side plate P 3  until positioned into the opening OP without blocking or being blocked by the corresponding first side plate P 3 . In addition, after the positioning block  1233   b  is positioned into the opening OP, the elastic deformation of the elastic portion  1231   b  may be restored to avoid elastic fatigue of the elastic arm  123   b  due to long-term use, which may thereby prolong the service life. 
     With reference to  FIG.  3 C  and  FIG.  3 D , each of the second side plates P 4  is adapted to be subject to a force to approach the corresponding first side plate P 3 , such that each of the bumps BP enters the fitting recess FR through the corresponding opening OP and pushes the corresponding positioning block  1233   b  away from the corresponding opening OP. At the same time, the elastic portion  1231   b  undergoes elastic deformation, such that each of the elastic arms  123   b  approaches the corresponding exterior wall surface S 2 . In this situation, the plug body  120   b  is adapted to slide along a horizontal direction PD to be separated from the fitting recess FR of the main body  110   b.    
     In other embodiments, the main body  110   a  of the embodiment shown in  FIG.  2 A  and  FIG.  2 B  may also use the plug assembly and the casing that are assembled in the embodiment of  FIG.  3 B , such that the main body  110   a  may replace a damaged plug assembly or casing. Reference may be made to the previous embodiments for related description, and details are not described herein. 
       FIG.  4 A  is a schematic perspective view of an electronic device with a detachable plug according to another embodiment of the disclosure.  FIG.  4 B  is a schematic perspective view of a storage state of a plug body of  FIG.  4 A . 
     With reference to  FIG.  4 A  and  FIG.  4 B , an electronic device  100 C with a detachable plug of this embodiment includes a main body  110   c  and a plug body  120   c . The difference between this embodiment and the previous embodiments lies in that the plug body  120   c  has a power pin group  121   c  and multiple storage grooves  123   c . The power pin group  121   c  is rotatably configured at the plug body  120   c . With reference to  FIG.  4 A , in the use state, the power pin group  121   c  protrudes from the storage grooves  123   c  of the plug body  120   c , and the power pin group  121   c  is used to be connected to a mains socket. With reference to  FIG.  4 B , in the storage state, the power pin group  121   c  rotates relative to the plug body  120   c  and enters the storage grooves  123   c  to facilitate reduction of the volume. 
       FIG.  5 A  is a schematic perspective view of a plug body according to another embodiment of the disclosure, and  FIG.  5 B  is a schematic exploded view of the plug body in  FIG.  5 A . 
     With reference to  FIG.  5 A  and  FIG.  5 B , a plug body  120   d  of this embodiment has a first casing  121   d , an elastic arm structural member  122   d , and a second casing  123   d . A power pin group  124   d  protrudes from a top surface TS of the first casing  121   d , and the elastic arm structural member  122   d  is disposed between the first casing  121   d  and the second casing  123   d . The elastic arm structural member  122   d  has a positioning portion  1221   d  and two elastic arms  1222   d . The two elastic arms  1222   d  are connected to two opposite sides of the positioning portion  1221   d , and the two elastic arms  1222   d  are bent and extended from the positioning portion  1221   d . The elastic arm  1222   d  of the elastic arm structural member  122   d  is similar to the elastic arm  123  (or the elastic arm  123   a ) of the previous embodiment, and details are not described herein. In detail, the first casing  121   d  has an accommodating space AS. When the plug body  120   d  is assembled, the second casing  123   d  is disposed in the accommodating space AS to clamp the elastic arm structural member  122   d , the positioning portion  1221   d  of the elastic arm structural member  122   d  is engaged in the first casing  121   d  and the second casing  123   d , and the connecting position between each elastic arm  1222   d  and the positioning portion  1221   d  (i.e., the bending position) is engaged in a groove PG on the side of the second casing  123   d , such that the two elastic arms  1222   d  extend out of the second casing  123   d  from the grooves PG. As shown in  FIG.  5 A  and  FIG.  5 B , the first casing  121   d  is provided with openings at the positions corresponding to the elastic arms  1222   d , such that the elastic arms  1222   d  may be exposed from the plug body  120   d  in order to fix the plug body  120   d  to the main body or disassemble the plug body  120   d  from the main body. In this embodiment, the elastic arm structural member  122   d , the first casing  121   d , and the second casing  123   d  are separately designed, which may reduce the difficulty of component manufacturing and maintain assembly convenience. 
     In summary, the electronic device with the detachable plug of the disclosure has the plug body detachably configured in the fitting recess of the main body and may replace plug bodies of corresponding specifications according to requirements to be applicable to mains sockets of different specifications. In addition, the main body and the plug body of the disclosure adopt a hidden connection structure, which may improve product appearance and reduce water ingress.
