     BACKGROUND 
     1. Field 
     The disclosure relates to an electronic device and, for example, to an electronic device including a flexible printed circuit board. 
     2. Description of Related Art 
     In line with the development of information/communication technologies and semiconductor technologies, there has been widespread use of various kinds of electronic devices at a rapid place. Electronic devices have been developed to be carried and used for communication. 
     Electronic devices may refer to devices configured to perform specific functions according to installed programs, such as home appliances, electronic wallets, portable multimedia players, mobile communication terminals, tablet PCs, video/audio devices, desktop/laptop computers, and vehicle navigation systems. For example, electronic devices may output stored information as sounds or images. In line with the high degree of integration of electronic devices and the widespread use of super-fast large-capacity wireless communication, it has recently become possible to equip a single electronic device (for example, mobile communication terminal) with various functions. For example, not only a communication function, but also an entertainment function (for example, gaming), a multimedia function (for example, music/video playback), communication and security functions for mobile banking and the like, a scheduling function, and an electronic wallet function may be integrated into a single electronic device. Such electronic devices have become compact such that they can be conveniently carrier by users. 
     Recently, portable electronic devices (for example, smartphones) may be compact and flat, and there are demands for high levels of integration and performance, such as application of latest antenna-related technologies. As a result, electronic devices have reduced inner spaces for disposing printed circuit boards, and circuit boards are thus made compact and disposed separately to be spaced apart. 
     Therefore, some electronic devices have a flexible printed circuit board so as to connect the printed circuit boards that are separated and spaced apart. 
     An electronic device (for example, smartphone or tablet PC) may include electrical components (for example, battery and camera), a printed circuit board electrically connected to the electrical components, and a flexible printed circuit board for connecting electrical components or connecting separated printed circuit boards. The flexible printed circuit board may occupy a space inside the electronic device, and may include a connector to be connected and/or fastened to printed circuit boards. 
     The flexible printed circuit board may be disposed adjacent to electrical components or support members inside the electronic device. When the user uses the electronic device, the electrical components or support members of the electronic device may have relative movements with reference to the housing (for example, casing) of the electronic device inside the electronic device. A specific part of the flexible printed circuit board may be pulled by the electrical components or support members, and the connector of the flexible printed circuit board coupled to the printed circuit board may be fractured or detached accordingly. 
     SUMMARY 
     Provided is an electronic device capable of reducing detachment of a connector of a flexible printed circuit board from a printed circuit board. 
     Also provided is an electronic device capable of limiting collision between an area of a flexible printed circuit board and another area thereof.

In embodiments, the connection region  363  may be disposed between the battery  350  and the rear plate  380 . For example, the connection region  363  may be spaced apart from the battery  350  by a predetermined distance and may be spaced apart from the rear plate  380  by a predetermined distance. According to another embodiment, the connection region  363  may be disposed between the battery  350  and the front plate  320 .

     In embodiments, at least one part of the first housing  421  may include a support member  421   a  configured to support the first printed circuit board  441 . The support member  421   a  may be disposed between the first printed circuit board  441  (e.g., the first printed circuit board  341  of  FIG.  4   ) and the battery module  450  (e.g., the battery  350  of  FIG.  4   ). For example, the support member  421   a  may limit the collision between the first printed circuit board  441  and the battery module  450 .

In another embodiment, the second housing  422  may be understood as at least a part of a housing (e.g., the housing  310  of  FIGS.  2  to  3   ). 
     In embodiments, the first printed circuit board  441  may be disposed between the first housing  421  and the second housing  422 . In embodiments, the first printed circuit board  441  may have at least one part supported by the first housing  421  and include a third connector  441   a  disposed on one surface (e.g., a surface facing in the −Z direction) thereof facing the second housing  422 . For example, the third connector  441   a  may be electrically and/or physically connected to the first connector  461   a - 1  of the flexible printed circuit board  460 . 
     According to various embodiments, the flexible printed circuit board  460  may include a bending part  461 , a first inclined part  464 , and a third flat part  463 . For example, at least one part of the flexible printed circuit board  460  may be disposed in the housing  420 , and may electrically connect a second printed circuit board (e.g., the second printed circuit board  342  of  FIG.  4   ) to a first printed circuit board  441 . 
     According to various embodiments, the bending part  461  may extend in a direction away from the second printed circuit board (e.g., the second printed circuit board  342  of  FIGS.  4  to  5   ) and then be bent so as to extend toward the second printed circuit board. 
     According to various embodiments, the bending part  461  may include a first flat part  461   a , a bent part  461   b , and/or a second flat part  461   c . In one embodiment, the bending part  461  may be understood as at least a part of a first region (e.g., the first region  361  of  FIGS.  4  to  5   ) of the flexible printed circuit board  460  connected to the first printed circuit board  441 . 
     In embodiments, the first flat part  461   a  may be disposed substantially parallel to the first printed circuit board  441 . For example, the first flat part  461   a  may extend from a part (e.g., a part where the first connector  461   a - 1  is disposed) connected to the first printed circuit board  441  in a direction (e.g., the +X direction) away from the second printed circuit board (e.g., the second printed circuit board  342  of  FIGS.  4  to  5   ). According to another embodiment, the first flat part  461   a  may be disposed to be inclined to form a predetermined angle (e.g., a predetermined angle with respect to the X-axis of  FIGS.  6 A to  6 B ) with respect to the first printed circuit board  441 , and may extend in a direction away from the second printed circuit board. 
     In embodiments, the first connector  461   a - 1  may be electrically and/or physically connected to the third connector  441   a  of the first printed circuit board  441 . In embodiments, the first printed circuit board  441  may be electrically connected to the second printed circuit board through a third connector  441   a , a first connector  461   a - 1 , a flexible printed circuit board  460 , and a second connector of the flexible printed circuit board  460 , and/or a fourth connector of the second printed circuit board. 
     In embodiments, a first end of the bent part  461   b  may be connected to a first end of the first flat part  461   a  (e.g., a part furthest from the second printed circuit board). In embodiments, a second end of the bent part  461   b  may be connected to a first end (e.g., a part furthest from the second printed circuit board) of the second flat part  461   c . In embodiments, the bent part  461   b  may have a shape curved toward the second printed circuit board. For example, at least one part of the bent part  461   b  may convexly protrude in a direction opposite to the second printed circuit board (e.g., the +X direction). 
     In embodiments, the second flat part  461   c  may be disposed substantially parallel to the first flat part  461   a . For example, the second flat part  461   c  may extend from the bent part  461   b  in a direction (e.g., the −X-axis direction of  FIGS.  6 A to  6 B ) in which the same becomes closer to the second printed circuit board. At least one part of the second flat part  461   c  may be disposed adjacent to the second housing  422 . According to another embodiment, the second flat part  461   c  may be inclined to form a predetermined angle with respect to the first flat part  461   a , and may extend in a direction in which the same becomes closer to the second printed circuit board. 
     In embodiments, a first end of the first inclined part  464  may be connected to the second end (e.g., a part closest to the second printed circuit board) of the second flat part  461   c . In embodiments, the first inclined part  464  may inclinedly extend to form a predetermined angle with respect to the longitudinal direction (e.g., the X-axis direction of  FIGS.  6 A to  6 B ) of the first housing  421 . For example, the first inclined part  464  may be disposed to be inclined toward a direction (e.g., the −X direction of  FIGS.  6 A to  6 B ) away from the first printed circuit board  441  and toward a direction (e.g., the −Z direction of  FIGS.  6 A to  6 B ) gradually away from the first housing  421 . 
     In embodiments, a first end of the third flat part  463  may be connected to the second end (e.g., a part furthest from the first printed circuit board  441 ) of the first inclined part  464 . In embodiments, the third flat part  463  may be disposed substantially parallel to the first housing  421 . In embodiments, the third flat part  463  may extend from the first inclined part  464  in a direction (e.g., the −X direction of  FIGS.  6 A to  6 B ) in which the same becomes closer to the second printed circuit board. In embodiments, at least one part of the third flat part  463  may be understood as a second region (e.g., the second region  362  of  FIGS.  4  to  5   ) of the flexible printed circuit board  460  connected to the second printed circuit board. 
     According to various embodiments, at least one part of the first inclined part  464  and/or the third flat part  463  of the flexible printed circuit board  460  may face an electrical component (e.g., the battery module  450 ). For example, the first inclined part  464  and/or the third flat part  463  of the flexible printed circuit board  460  may be disposed to be spaced apart from the electrical component (e.g., the battery module  450 ) by a predetermined distance. 
     In embodiments, at least one part of the electrical component (e.g., the battery module  450 ) of the electronic device  101  may be fixed and/or supported by the first housing  421 . 
     According to various embodiments, the buffer member  470  may be disposed inside the bent part  461 . In embodiments, the buffer member  470  may be disposed between the first flat part  461   a  and the second flat part  461   c . For example, the height (h 1 ) (e.g., the length in the Z-axis direction) of the buffer member  470  may be smaller than the spacing distance (s 1 ) between the first flat part  461   a  and the second flat part  461   c . For example, the buffer member  470  may be formed of an elastic member, such as rubber or synthetic resin, and may limit a direct collision between the first flat part  461   a  and the second flat part  461   c . For another example, the buffer member  470  may be formed of various members limiting a direct collision between the first flat part  461   a  and the second flat part  461   c . In embodiments, the buffer member  470  may be disposed on one surface (e.g., a surface facing in the −Z direction of  FIGS.  6 A to  6 B ) of the first flat part  461   a . According to another embodiment, the buffer member  470  may be disposed on one surface (e.g., a surface facing in the +Z direction) of the second flat part  461   c . According to still another embodiment, the buffer member  470  may be disposed on one surface (e.g., a surface facing in the +X direction) of the reinforcing member  490 . According to various embodiments, the buffer member  470  may be disposed between one part (e.g., the first flat part  461   a ) of the bending part  461  and the other part (e.g., the second flat part  461   c ) of the bending part facing the one part of the bending part. In embodiments, the buffer member  470  may be disposed between the first flat part  461   a  and the second flat part  461   c  facing the first flat part  461   a.    
     According to various embodiments, at least one part of the reinforcing member  490  may be coupled to the flexible printed circuit board  460 . In embodiments, the reinforcing member  490  may be coupled to a surface of the flexible printed circuit board  460  opposite to the surface to which the first connector  441   a  is coupled. For example, the first connector  441   a  may be coupled to the first surface (e.g., a surface facing in the +Z direction) of the first flat part  461   a , and the reinforcing member  490  may be coupled to the second surface (e.g., a surface facing in the −Z direction) of the first flat part  461   a . In embodiments, at least one part of the reinforcing member  490  may include a protrusion (e.g., the protrusion  492  of  FIG.  7   ) configured to support the housing (e.g., the second housing  422 ). 
     Hereinafter, a state before and after deformation of the bending part  461  will be described with reference to  FIGS.  6 A and  6 B . 
     Referring to  FIG.  6 A , the bending part  461  may be disposed at a first position before being deformed. In embodiments, in a state in which the bending part  461  is disposed at the first position, the first inclined part  464  and/or the third flat part  463  of the flexible printed circuit board  460  may be maintained to be spaced apart from the battery module  450 . The electronic device  101  may be pressed in an unspecified direction during the use thereof. In this case, the electrical component (e.g., the battery module  450 ) of the electronic device  101  may move inside the electronic device  101 , relative to the electronic device  101 . For example, the battery module  450  may move inside the electronic device  101  in one direction (e.g., the −Z direction). The movement of the battery module  450  may be restricted in the longitudinal direction (e.g., the X-axis direction) of the battery module  450  by the support member  421   a  and/or the second printed circuit board. The movement of the battery module  450  may be restricted in one direction (e.g., the +Z direction) among the thickness directions (e.g., the Z-axis directions) of the battery module  450  by the first housing  421 . The battery module  450  may move inside the electronic device  101  in one direction (e.g., the −Z direction) by an impact or force applied to the electronic device  101 . When the battery module  450  moves in one direction (e.g., the −Z direction), the battery module  450  may collide with at least one part of the first inclined part  464  and/or at least one part of the third flat part  463 . The first inclined part  464  and/or the third flat part  463  may move in one direction (e.g., −Z direction) by the battery module  450 , and accordingly, a force (e.g., a force pulling in the −X direction) may be applied to the bending part  461  such that the bending part  461  connected to the first inclined part  464  is pulled toward the second printed circuit board. 
     Referring to  FIG.  6 B , the bending part  461  may be disposed at the second position after being deformed. The second flat part  461   c  may move a predetermined distance from the first position (e.g., the position of the second flat part  461   c  of  FIG.  6 A ) toward the second printed circuit board to be disposed at the second position. The bent part  461   b  may be bent at the first position (e.g., the position of the bent part  461   b  of  FIG.  6 A ) toward the second printed circuit board and thus be disposed at the second position. At least one part (e.g., a part connected to the bent part  461   b  and a part adjacent thereto) of the first flat part  461   a  may be bent toward the second printed circuit board. The position of the other part (e.g., a part to which the first connector  461   a - 1  is coupled and a part adjacent thereto) of the first flat part  461   a  may be fixed despite a force applied to the bending part  461 . When the second flat part  461   c  moves a predetermined distance, a part of the bent part  461   b  and/or a part of the first flat part  461   a  may be bent and deformed to accommodate the amount of movement, so that a part of the first flat part  461   a  to which the first connector  461   a - 1  is coupled may not move. Accordingly, in the electronic device  101  of the disclosure, even when a force by an electrical component (e.g., the battery module  450 ) acts on the flexible printed circuit board  460 , the escape of the first connector  461   a - 1  from the third connector  441   a  of the first printed circuit board  441  may be restricted. 
     According to another embodiment, the structure and/or arrangement relationship of the bending part  461 , the buffer member  470 , and/or the reinforcing member  490  may be formed on a region (e.g., the second region  362  of  FIG.  5   ) connected to the second printed circuit board (e.g., the second printed circuit board  342  of  FIGS.  4  to  5   ) of the flexible printed circuit boards  460  (e.g., the flexible printed circuit board  360  of  FIGS.  4  to  5   ). 
       FIG.  7    is a cross-sectional view taken along line B-B′ of  FIG.  5    according to various embodiments of the disclosure. 
     Referring to  FIG.  7   , the electronic device  101  according to various embodiments may include a second housing  422 , a flexible printed circuit board  460 , a reinforcing member  490 , and/or a first printed circuit board  441 . The configuration of the second housing  422 , the flexible printed circuit board  460 , the reinforcing member  490 , and/or the first printed circuit board  441  of  FIG.  7    may be partially or entirely the same as that of the second housing  422 , the flexible printed circuit board  460 , the reinforcing member  490 , and/or the first printed circuit board  441  of  FIGS.  6 A to  6 B . 
     According to various embodiments, one surface (e.g., a surface facing in the +Z direction) of the reinforcing member  490  may be coupled to at least a part (e.g., the first flat part  461   a ) of the flexible printed circuit board  460 . In embodiments, the width of the reinforcing member  490  may be substantially the same as the width of the first flat part  461   a . According to another embodiment, the width of the reinforcing member  490  may be smaller or greater than the width of the first flat part  461   a.    
     According to various embodiments, at least one part of the reinforcing member  490  may include a protrusion  492  configured to support the housing (e.g., the second housing  422 ). For example, the protrusion  492  may have one surface (e.g., a surface facing in the −Z direction) directly or indirectly supporting the second housing  422 , so that the spacing distance between the second housing  422  and the first printed circuit board  441  can be maintained. In one embodiment, it may be understood that at least one part (e.g., the protrusion  492 ) of the reinforcing member  490  is coupled to the housing (e.g., the second housing  422 ). 
     In embodiments, the protrusion  492  may include a first protrusion  492   a , and a second protrusion  492   b  spaced apart from the first protrusion  492   a  in the width direction of the housing (e.g., the second housing  422 ). In embodiments, the thickness of the protrusion  492  (e.g., the thickness of the first protrusion  492   a  and the thickness of the second protrusion  492   b , and the length in the Z-axis direction) may be greater than the thickness of the flexible printed circuit board  460 . For example, the thickness of the protrusion  492  (e.g., the thickness of the first protrusion  492   a  and the thickness of the second protrusion  492   b ) may be greater than the thickness of the second flat part  461   c  (e.g., the length in the Z-axis direction). In embodiments, the spacing distance (s 2 ) between the first protrusion  492   a  and the second protrusion  492   b  may be greater than the width (w 1 ) (e.g., the length in the Y-axis direction) of the flexible printed circuit board  460 . In one embodiment, since the thickness of the first and second protrusions  492   a  and  492   b  and the spacing distance therebetween are greater than the thickness and width of the second flat par  461   c , the second flat part  461   c  may be allowed to move in a movable space  490   a  formed by the second housing  422 , the protrusion  492 , and the reinforcing member  490 . For example, the second flat part  461   c  may secure a space enabling the same to move in the movable space  490   a  in the width direction (e.g., the Y-axis direction) and/or the thickness direction (e.g., the Z-axis direction) of the second housing  422 . In another embodiment, the movable space  490   a  may be understood as an element of the reinforcing member  490 . For example, the reinforcing member  490  may include a first surface facing in the first direction (e.g., the −Z direction of  FIG.  7   ), a second surface facing in the second direction (e.g., the +Z direction of  FIG.  7   ) facing a direction opposite to the first direction, and the movable space  490   a  recessed in at least one part of the first surface toward the second direction. In another embodiment, the depth (e.g., the length in the Z-axis direction of  FIG.  7   ) of the movable space  490   a  may be greater than the thickness of the flexible printed circuit board  460  (e.g., the thickness (e.g., the length in the Z-axis direction of  FIG.  7   )) of the second flat part  461   c . In another embodiment, the width (e.g., the length in the Y-axis direction of  FIG.  7   ) of the movable space  490   a  may be greater than the width of the flexible printed circuit board  460  (e.g., the width (e.g., the length in the Y-axis direction of  FIG.  7   ) of the second flat part  461   c ). 
       FIG.  8 A  is a front view of a flexible printed circuit board before a bending part of an electronic device is formed, according to various embodiments of the disclosure,  FIG.  8 B  is a rear view of a flexible printed circuit board before a bending part of an electronic device is formed, according to various embodiments of the disclosure, and  FIG.  8 C  is a rear perspective view of a flexible printed circuit board before a bending part of an electronic device is formed, according to various embodiments of the disclosure. 
     The configuration of the flexible printed circuit board  560  of  FIGS.  8 A to  8 C  may be partially or entirely the same as that of the flexible printed circuit board  360  of  FIGS.  4  to  5    and/or the configuration of the flexible printed circuit board  460  of  FIGS.  6  to  7   . The configuration of the buffer member  570  of  FIGS.  8 A to  8 C  may be partially or entirely the same as that of the buffer member  470  of  FIGS.  6  to  7   . The configuration of the reinforcing member  590  of  FIGS.  8 A to  8 C  may be partially or entirely the same as that of the reinforcing member  490  of  FIGS.  6  to  7   . 
     According to various embodiments, the flexible printed circuit board  560  may include a first region  561 , a second region  562 , and/or a connection region  563 . 
     In embodiments, the flexible printed circuit board  560  may include a first connector  561   a - 1  (e.g., the first connector  461   a - 1  of  FIGS.  6  to  7   ) disposed on the front surface (e.g., the surface shown in  FIG.  8 A ) of the first region  561  (e.g., the first region  361  of  FIGS.  4  to  5   ). In one embodiment, the first connector  561   a - 1  may be electrically and/or physically connected to a first printed circuit board (e.g., the first printed circuit board  341  of  FIGS.  4  to  5   ). In one embodiment, the first connector  561   a - 1  may be understood as at least a part of the flexible printed circuit board  560 .
