CLAIM OF PRIORITY 
     This application claims priority from and the benefit, under 35 U.S.C. §119(a), of Korean patent application no. 10-2015-0072796, filed on May 26, 2015, which is hereby incorporated by reference in its entirety. 
     BACKGROUND 
     Technical Field 
     Various exemplary embodiments of the present disclosure relate to an electronic device having a magnetic body and a connection member in order to connect a Printed Circuit Board (PCB) and an electronic component therein. 
     Description of the Related Art 
     In general, an electronic device such as a mobile terminal includes an electrically conductive member having a predetermined elastic force in order to transfer an electric signal between a PCB and a component terminal. Such an electrically conductive member performs a function of receiving an electric signal from the PCB and transferring an electric signal to each component through a terminal mounted in each component. 
     In order to prevent a contact point from being separated because of an external impact, the electrically conductive member has an elastic force and is located between the PCB. The electrically conductive member is designed to have a repulsive force of a predetermined value or more. Therefore, by such a repulsive force, the electrically conductive member applies a predetermined pressure to the PCB or the terminal connected to both ends thereof. While such a pressure is maintained, when an unintended impact occurs or an excessive pressure occurs in the electronic device, a problem may occur. For example, the electrically conductive member damages a component connected to both ends thereof or a component connected to both ends thereof is lifted. 
     In particular, when the terminal connected to the electrically conductive member is mounted in an antenna structure body, there is a problem that minute damage (e.g., crack phenomenon, structure body lifting phenomenon according to a repulsive force) may have a serious influence on an antenna performance deviation. Nothing in the foregoing discussion of the state of the art is to be construed as an admission of the prior art.

In order to cover a partial area of the rear case  170 , an upper portion of the antenna structure body  200  may be coupled to the rear case  170 , and by penetrating a portion of the rear case  170 , a bottom surface of a lower portion of the antenna structure body  200  may be coupled to the rear case  170  so as to expose in a PCB (not shown) direction.

The antenna structure body  200  of  FIG. 2B  may include an antenna radiating body. 
     According to another exemplary embodiment, the electronic device  100  may include a rear external type antenna structure body  200  and a rear case  170 , as shown in  FIG. 2C . The antenna structure body  200  may be received in a groove of the rear case  170 , and a portion of a lower portion of the antenna structure body  200  may be coupled to the rear case  170  to be exposed toward the PCB in a hole of the rear case  170 . As in  FIGS. 2A  and  2 B, the antenna structure body  200  of  FIG. 2C  may include an antenna radiating body. 
       FIGS. 3A to 3D  are diagrams illustrating a structure of a connection member  400  according to a magnetic body mounting location in an electronic device  100  according to various exemplary embodiments of the present disclosure. 
     For convenience of description, it is assumed that the antenna structure body  200  and the rear case  170  are the rear external carrier type antenna structure body  200  and the rear case  170  of  FIG. 2A . In the following exemplary embodiment, such a connection member  400  may be defined as a damping contact member  400 . 
     According to an exemplary embodiment, as a magnetic body  500 , a Neodymium (ND) magnet may be used, and in order to prevent oxidation and corrosion and to improve electric conductivity, the magnetic body  500  may be plated with gold or nickel. According to various exemplary embodiments of the present disclosure, the magnetic body  500  may have various intensities. For example, in order to maintain a contact point between the damping contact member  400  and the magnetic body  500 , the magnetic body  500  may be formed with a magnet having a magnetic force corresponding to pressing amount specification information of the damping contact member  400 . The magnetic body  500  shown in the following drawings may have various lengths and shapes according to a connection structure of the damping contact member  400  and an electronic component of the electronic device  100 . 
     According to an exemplary embodiment, when an external impact is applied, the damping contact member  400  may have a structure that provides a damper function. For this reason, the damping contact member  400  may be implemented in a shape “Z”, and the entire or a portion of the damping contact member  400  may be made of a material having a predetermined elastic force. In this case, in order to minimize a repulsive force of the damping contact member  400 , a pressing amount of the damping contact member  400  may be designed to correspond to a predetermined specification. Further, the damping contact member  400 , a terminal of the antenna structure body  200 , and a PCB  300  may be made of a material (e.g., ferromagnetic substance) that can contact with the magnetic body  500  by a magnetic force and may be made of a material having electric conductivity. 
     According to an exemplary embodiment, the PCB  300  may be a main PCB that supplies a signal such as a current to each component terminal within the electronic device  100 . The PCB  300  may further have a structure related to a corresponding component by the damping contact member  400  according to a component connected to the PCB  300 . For example, when the damping contact member  400  is connected to the terminal of the antenna structure body  200 , the PCB  300  may include a power supply unit for supplying a current to the terminal. 
     One end of the damping contact member  400  may be fixed to the antenna structure body  200  or the rear case  170 . For example, one end of the damping contact member  400  may be soldered to be fixed to the antenna structure body  200  or the PCB  300 . 
     Further, the other end of the damping contact member  400  may be connected to the magnetic body  500  in a form contacting with the magnetic body  500  by a magnetic force of the magnetic body  500 . Such a magnetic body  500  may be mounted in the terminal of the antenna structure body  200 , the PCB  300 , or the damping contact member  400 . 
     According to an exemplary embodiment, the electronic device  100  may have a structure in which the magnetic body  500  is mounted in the PCB  300 , as shown in  FIG. 3A . For example, the magnetic body  500  of  FIG. 3A  may be fixed to the PCB  300  by soldering. 
     According to an exemplary embodiment, an upper surface, which is one end of the damping contact member  400  may be fixed to the antenna structure body  200 . For example, an upper surface of the damping contact member  400  may be fixed to the terminal of the antenna structure body  200  by soldering. 
     According to an exemplary embodiment, a lower surface, which is the other end of the damping contact member  400 , may contact with the magnetic body  500  by a magnetic force. For example, a lower surface of the damping contact member  400  may rotate or may be inclined toward the magnetic body  500  by attraction. Such an inclination operation or a rotation operation may be performed through a structure of  FIGS. 4 to 8  to be described later. 
     The damping contact member  400  of  FIG. 3A  electrically connects the terminal of the antenna structure body  200  and the PCB  300  in which the magnetic body  500  is mounted, and one end thereof is fixed to the terminal of the antenna structure body  200  and the other end thereof contacts with the magnetic body  500  by a magnetic force. 
     According to an exemplary embodiment, the electronic device  100  may have a structure in which the magnetic body  500  is mounted in the antenna structure body  200 , as shown in  FIG. 3B . For example, the magnetic body  500  of  FIG. 3B  may be fixed to the terminal of the antenna structure body  200  by soldering or may be embedded in the terminal of the antenna structure body  200 . 
     In this case, unlike  FIG. 3A , a lower surface of the damping contact member  400  may be fixed to the PCB  300 . For example, a lower surface, which is one end of the damping contact member  400  may be fixed to the PCB  300  by soldering. Further, an upper surface, i.e., the other end of the damping contact member  400 , may contact with the magnetic body  500  by a magnetic force. For example, an upper surface of the damping contact member  400  may rotate or may be inclined toward the magnetic body  500  by attraction. Such an inclination operation or a rotation operation may be performed through a structure of  FIGS. 4 to 8  to be described later. 
     The damping contact member  400  of  FIG. 3A  may electrically connect the PCB  300  and the terminal of the antenna structure body  200  in which the magnetic body  500  is embedded, and one end thereof may be fixed to the PCB  300  and the other side thereof contacts with the magnetic body  500  by a magnetic force. 
     According to an exemplary embodiment, the electronic device  100  may have a structure in which the magnetic body  500  is mounted in the damping contact member  400 , as shown in  FIGS. 3C and 3D . For example, the magnetic body  500  may be mounted or embedded at any one end (e.g., an upper surface or a lower surface) of the damping contact member  400 . As shown in  FIGS. 3C and 3D , the embedded magnetic body  500  may be embedded at the inside of the damping contact member  400  not to be viewed from the outside of the damping contact member  400 . 
     As shown in  FIG. 3C , the electronic device  100  may have a structure in which the magnetic body  500  is embedded in an upper portion of the damping contact member  400 . According to an exemplary embodiment, a lower surface of the damping contact member  400  may be fixed to the PCB  300 . For example, a lower surface, which is one end of the damping contact member  400 , may be fixed to the PCB  300  by soldering. Further, an upper portion of the damping contact member  400  may contact with the terminal of the antenna structure body  200  by a magnetic force of the magnetic body  500  embedded in an upper portion of the damping contact member  400 . For example, the upper portion of the damping contact member  400  may rotate or may be inclined to contact with the terminal of the antenna structure body  200  by a magnetic force. For this reason, the damping contact member  400  may have a structure of  FIGS. 4 to 8  to be described later. 
     As shown in  FIG. 3D , the electronic device  100  may have a structure in which the magnetic body  500  is embedded in a lower portion of the damping contact member  400 . According to an exemplary embodiment, an upper surface of the damping contact member  400  may be fixed to the terminal of the antenna structure body  200 . For example, an upper surface, which is one end of the damping contact member  400 , may be fixed to the terminal of the antenna structure body  200  by soldering. Further, the lower portion of the damping contact member  400  may contact with the PCB  300  by a magnetic force of the magnetic body  500 . For example, the lower portion of the damping contact member  400  may rotate or may be inclined to contact with the PCB  300  by a magnetic force. For this reason, the damping contact member  400  may have a structure of  FIGS. 4 to 8  to be described later. 
     As described above, a structure of the damping contact member  400  may be connected in a form in which one end thereof is fixed to a first component (e.g., terminal) and in which the other end thereof contacts with a second component (e.g., a PCB) by a magnetic force of the magnetic body. By minimizing a repulsive force of the damping contact member  400  by a fixing structure of the damping contact member  400  and a contact structure using the magnetic body  500 , physical damage of the antenna structure body  200  or the PCB  300  can be minimized. 
       FIG. 4  is a side view illustrating a damping contact member  400  according to an exemplary embodiment of the present disclosure. The damping contact member  400  of  FIG. 4  specifically illustrates a connection structure of the damping contact member  400  of  FIGS. 3A to 3D . Such a damping contact member  400  may include a first portion  410  and a second portion  450 . 
     The first portion  410  may be fixed to a specific component within the electronic device  100 . For example, the first portion  410  may be fixed to the terminal or the PCB  300  within the electronic device  100  by soldering. Specifically, an upper surface of the first portion  410  may be fixed to the terminal or the PCB  300  by soldering to perform a point contact, line contact, or surface contact. As at least a portion of the first portion  410  is fixed to another component, such a first portion  410  fixes the damping contact member  400 . As shown in  FIG. 4 , the first portion  410  may be formed in a “7”-shaped portion in a “Z” shaped damping contact member  400 . According to various exemplary embodiments, in the first portion  410 , a “−” shaped horizontal surface and a “/” shaped diagonal surface may be integrally formed in one piece. In order to provide a damper function, the first portion  410  may be formed in a predetermined thickness, and such a first portion may have a thickness different from or the same thickness as that of the second portion  450 . 
     It is shown that the first portion  410  of  FIG. 4  forms an upper portion of the damping contact member  400 , but it may form a lower portion of the damping contact member  400  according to a location and direction in which the damping contact member  400  is inserted within the electronic device  100 . For example, as shown in  FIGS. 3B and 3C , the first portion  410  may be formed in a “∠” shape, and a portion “_”, which is a lower surface, may be fixed to the PCB  300  by soldering. 
     The second portion  450  may directly contact with the magnetic body  500  by a magnetic force of the magnetic body  500  or may contact with a specific component within the electronic device  100  by including the magnetic body  500 . According to an exemplary embodiment, the second portion  450  of the damping contact member  400  may be moveably connected to the first portion  410 . As shown in  FIG. 4 , such a second portion  450  may be formed in a “_” or “−” shaped portion in a “Z”-shaped damping contact member  400 . It is to be understood that that “_” and “−” shaped portions refer to the upper and lower substantially parallel surfaces of the Z-shape. 
     As described above, because the damping contact member  400  forms a “Z”-shaped structure by coupling of the first portion  410  and the second portion  450 , the damping contact member  400  may stably provide a damper function, unlike an existing “C”-shaped connection member. Specifically, because the damping contact member  400  includes a flat surface in an upper portion and a lower portion, even if the damping contact member  400  vertically receives a load, the damping contact member  400  may stably perform a damper function. 
     According to an exemplary embodiment, the damping contact member  400  may include a connection portion  455 , which may be hinged, that connects the first portion  410  and the second portion  450 . The connection portion  455  may have a structure that guides the second portion  450  to rotate relative to the first portion  410 . Such a connection portion  455  may have a form of a hinge structure such that the second portion  450  coupled to the first portion  410  rotates. 
     According to various exemplary embodiments, the connection portion  455  may be formed with at least one protruding portion formed at one end of the first portion  410  and at least one housing hole formed at one end of the second portion  450  and that houses a protruding portion. In this case, the housing hole may be formed at a location that contacts with one end of the first portion  410 . When the protruding portion and the housing hole are coupled, the connection portion  455  may be formed in a predetermined specification such that the second portion  450  rotates based on the coupling. 
     The connection portion  455  of  FIG. 4  is generated by coupling of a partial area of the first portion  410  changed to a protruding portion and a partial area of the second portion  450  changed to a housing hole, but the present disclosure is not limited thereto. For example, the connection portion  455  may be formed in an independent configuration separate from the second portion  450  and the first portion  410 . In this case, the connection portion  455 , the second portion  450 , and the first portion  410  may include various connection means for a mutual connection. Further, the connection portion  455  may be generated by extension from or change of at least one of the first portion  410  and the second portion  450 . 
     According to various exemplary embodiments, it may be described that a structure of the damping contact member  400  is a change structure of the first portion  410  and the second portion  450  without necessity to separately define a structure of the damping contact member  400  by the connection portion  455 . For example, the first portion  410  of the damping contact member  400  may form at least one protruding portion at one end, and the second portion  450  may form at least one housing hole that houses the protruding portion at a location that contacts with one end of the first portion  410 . By coupling of the protruding portion and the housing hole, the second portion  450  may be rotatably coupled to the first portion  410 . 
     Further, the first portion  410  of the damping contact member  400  may form at least one fixing groove at one end, and the second portion  450  may form at least one corresponding groove facing the fixing groove at a location that contacts with one end of the first portion  410 . In this case, the damping contact member  400  may further include a fixing pin that fixes the first portion  410  and the second portion  450 . In particular, the fixing pin may penetrate the fixing groove and the corresponding groove. Various kinds and sizes of such a fixing pin may be used. By coupling of the fixing groove, the corresponding groove, and the fixing pin, the second portion  450  may be rotatably coupled relative to the first portion  410 . 
     According to an exemplary embodiment, the damping contact member  400  may include a stopper  415  that limits the second portion  450  from rotating in a direction that reduces an angle in which the second portion  450  forms with the first portion  410 . Such a stopper  415  may be formed by change of an area of at least one of the first portion  410  and the second portion  450  or may be mounted between the first portion  410  and the second portion  450  as an independent structure body. According to an exemplary embodiment, the stopper  415  of  FIG. 4  may protrude in a convex form from a partial area of the first portion  410  toward the second portion  450 . For example, the stopper  415  may protrude from one side of the first portion toward the second portion. 
     Such a stopper  415  limits the second portion  450  from rotating toward the first portion  410  to enable the damping contact member  400  to maintain a damper function. Specifically, when a lateral pressure is vertically applied to the damping contact member  400  as may result from an unintended impact to the electronic device  100 , the stopper  415  may prevent the second portion  450  from rotating toward the first portion  410  to support the damping contact member  400  to maintain a damper structure. In a state in which the stopper  415  does not exist, when a lateral pressure occurs, the second portion  450  rotates toward the first portion  410  and thus a “Z”-shaped damper structure may be collapsed. 
     The damping contact member  400  electrically connects the terminal and the PCB  300  of the electronic device  100  to transfer a signal (e.g., electrical signal) collected from the PCB  300  to the terminal. Further, the damping contact member  400  may include a first portion  410  fixed to a first component of the electronic device  100  and a second portion  450  rotatably connected to the first portion  410  and that contacts with the magnetic body  500  or a second component of the electronic device  100  by a magnetic force of the magnetic body  500 . Further, the damping contact member  400  further includes a connection portion  455  to connect the first portion  410  and the second portion  450 . In a state in which the first portion  410  is fixed to the first component of the electronic device  100 , the second portion  450  contacts with the magnetic body  500  or a second component of the electronic device  100  by a magnetic force, thereby minimizing a repulsive force because of the damping contact member  400 . 
     Unlike a case in which a “C”-shaped damping member is coupled between the first component and the second component of the electronic device  100 , because the damping contact member  400  according to various exemplary embodiments of the present disclosure has a structure in which a portion is fixed and other portions thereof rotate by a magnetic force, the damping contact member  400  may connect the PCB  300  and the terminal in a state in which a repulsive force is minimized. Thereby, damage that may occur in an internal component of the electronic device  100  can be minimized because of a repulsive force. 
     Further, the damping contact member  400  according to various exemplary embodiments of the present disclosure is formed in a “Z”-shaped structure that includes a stopper  415  and in which the second portion  450  is prevented from rotating toward the first portion  410 ; thus, an external impact can be effectively absorbed. 
       FIG. 5  is a front view illustrating the damping contact member  400  of  FIG. 4  viewed in a direction {circle around (1)} according to an exemplary embodiment of the present disclosure,  FIG. 6  is a rear view illustrating the damping contact member  400  of  FIG. 4  viewed in a direction {circle around (2)} according to an exemplary embodiment of the present disclosure, and  FIG. 7  is a perspective view illustrating the damping contact member of  FIG. 4  according to an exemplary embodiment of the present disclosure. 
     A description of constituent elements identical to or corresponding to the damping contact member  400  of  FIG. 4  in relation to the damping contact member  400  of  FIGS. 5 to 7  may be omitted. 
     According to various exemplary embodiments, the damping contact member  400  may be made of a ferromagnetic substance that can move according to magnetism. Further, the damping contact member  400  may be made of a Steel Use Stainless (SUS)-based material. In order to prevent oxidation and corrosion and to improve electric conductivity, gold or nickel plating may be applied to the outside of the damping contact member  400 . 
       FIG. 8  is an exploded perspective view illustrating a detailed coupling structure of the damping contact member  400  of  FIG. 4  according to an exemplary embodiment of the present disclosure. 
     In a description of  FIG. 8 , constituent elements identical to or corresponding to those in a description of  FIG. 4  may be omitted. 
     As shown in  FIG. 8 , the damping contact member  400  may be formed by coupling of the first portion  410  and the second portion  450 . For this reason, the first portion  410  may have a protruding portion  417  at both side portions of one end, and the second portion  450  may have a housing hole  457  at both side portions of one end so as to house the protruding portion  417 . In order to insert and fix the protruding portion  417  into the housing hole  457 , one end of the second portion  450  may be extended in a predetermined height. By coupling the protruding portion  417  of the first portion  410  and the housing hole  457  of the second portion  450 , a connection portion of the damping contact member  400  may be formed. 
     Although not shown in  FIG. 8 , a connection portion according to various exemplary embodiments of the present disclosure may include at least one fixing groove formed at one end of the first portion  410 , at least one corresponding groove formed opposite to the fixing groove, and a fixing pin that fixes the first portion  410  and the second portion  450  by penetrating the fixing groove and the corresponding groove. In this case, the corresponding groove may be formed in an area of the second portion  450  that contacts with one end of the first portion  410 . 
     Further, according to various exemplary embodiments of the present disclosure, in the damping contact member  400 , the first portion  410  and the second portion  450  may be integrally formed. For example, the second portion  450  may be extended to the first portion  410 . In this case, the second portion  450  may contact with the magnetic body  500  or a specific component of the electronic device  100  by a magnetic force of the magnetic body  500 . According to an exemplary embodiment, the second portion  450  may be made of a material having flexibility larger than that of the first portion  410 . Thereby, the second portion  450  may be bent by a magnetic force of the magnetic body  500 , and a bent portion may contact with the magnetic body  500  or a specific electronic component of the electronic device  100 . 
     As described above, the damping contact member  400  may guide a rotation of the second portion  450  through a configuration of a connection portion according to various exemplary embodiments. Thereby, the damping contact member  400  may stably connect the terminal and the PCB  300  while minimizing a repulsive force thereof. 
       FIG. 9  is a diagram illustrating a state in which the damping contact member  400  and the magnetic body (not shown) are located between a key FPCB and the PCB  300  according to various exemplary embodiments of the present disclosure. The key FPCB (or key PCB) is connected to a side key  800  to recognize pressing information of the side key  800  and may include a key FPCB contact terminal  700 . Such a key FPCB contact terminal  700  may collect a signal from the PCB  300  or may provide a signal collected from the side key  800  to the PCB  300 . 
     The electronic device  100  may mount the key FPCB contact terminal  700 , the damping contact member  400 , and the PCB  300 . Such a key FPCB contact terminal  700 , damping contact member  400 , and PCB  300  may be supported by the rear case  170 . Components of  FIG. 9  are shown to describe a specific portion of the electronic device  100 , and the electronic device  100  according to various exemplary embodiments of the present disclosure is not limited to such components. 
     The key FPCB contact terminal  700  may correspond to an antenna terminal included in the antenna structure body  200  of  FIGS. 2A to 3D . The damping contact member  400  of  FIG. 9  may correspond to the damping contact member  400  of  FIGS. 3 to 8 . Further, the PCB  300  of  FIG. 9  may correspond to the PCB  300  of  FIGS. 3A to 3D . Further, in the key FPCB contact terminal  700  and the PCB  300 , the magnetic body (not shown) may be mounted to correspond to a location of the magnetic body  500  of  FIGS. 3A to 3D . 
     A difference between a configuration of  FIG. 9  and a configuration of the foregoing drawings is that the damping contact member  400  and the magnetic body (not shown) may be connected to other components other than the antenna structure body  200 . In other words, the damping contact member  400  of  FIG. 9  is located between the key FPCB contact terminal  700  and the PCB  300  to provide a damper function and a contact point function. Further, the magnetic body (not shown) may be mounted or embedded in at least one of the key FPCB contact terminal  700 , the PCB  300 , and the damping contact member  400  with the same principle as that of  FIGS. 3A to 3D . 
       FIG. 10  is a diagram illustrating a state in which the damping contact member  400  and the magnetic body (not shown) are located between a motor FPCB and the PCB  300  according to various exemplary embodiments of the present disclosure. 
     The motor FPCB is connected to a motor  600  to recognize driving information of the motor  600  and may include a motor FPCB contact terminal  700 . Such a motor FPCB contact terminal  700  may collect a signal from the PCB  300  or may provide a signal collected from the motor  600  to the PCB  300 . 
     A difference between a configuration of  FIG. 10  and a configuration of the foregoing drawings is that the damping contact member  400  and the magnetic body (not shown) may be connected to other components other than the antenna structure body  200  and the key FPCB contact terminal  700 . In other words, the damping contact member  400  of  FIG. 10  is located between the motor FPCB contact terminal  700  and the PCB  300  to provide a damper function and a contact point function. Further, the magnetic body (not shown) may be mounted or embedded in at least one of the motor FPCB contact terminal  700 , the PCB  300 , and the damping contact member  400  with the same principle as that of  FIGS. 3A to 3D . 
     In exemplary embodiments described in relation to  FIGS. 9 and 10 , the damping contact member  400  and the magnetic body (not shown) according to various exemplary embodiments of the present disclosure may be connected to various electronic components within the electronic device  100 . In this case, similarly, the damping contact member  400  and the magnetic body (not shown) may maintain a contact point between components by minimizing a repulsive force of the damping contact member  400  and provide a stable damper function by a structure of the damping contact member  400 . 
     Further,  FIGS. 9 and 10  illustrate that the PCB  300  and a specific FPCB of electronic components of the electronic device  100  are connected through the damping contact member  400  and the magnetic body (not shown), but the present disclosure is not limited thereto. The damping contact member  400  and the magnetic body (not shown) according to various exemplary embodiments of the present disclosure may function as a contact structure between the PCB  300  and the FPCB and function as a contact structure of the FPCB and the PCB  300  regardless of a kind and form of a component. 
       FIG. 11A  is a diagram illustrating a damping contact member  400  and a magnetic body  500  according to various exemplary embodiments of the present disclosure, and  FIG. 11B  is a diagram illustrating an electronic device  100  further including a strength reinforcing member  250  according to a kind of a rear case  170 . 
     As shown in  FIG. 11A , the electronic device  100  may include a rear case  170 , antenna structure body  200 , PCB  300 , damping contact terminal  400 , and magnetic body  500 . A configuration of the electronic device  100  of  FIG. 11A  may correspond to a structure of  FIG. 2A  or  FIG. 2B . 
     According to an exemplary embodiment, the antenna structure body  200  may be classified into a flexible type (FPCB structure) and a hard type (carrier structure or SUS structure) according to a material. In a case of  FIG. 11A , because an upper portion of the antenna structure body  200  is supported by the rear case  170 , the antenna structure body  200  is not lifted or pulled by the damping contact member  400  regardless of a material. 
     The electronic device  100  of  FIG. 11B  may include a rear case  170 , antenna structure body  200 , strength reinforcing member  250 , PCB  300 , damping contact member  400 , and magnetic body  500 . A configuration of the electronic device  100  of  FIG. 11B  may correspond to a structure of  FIG. 3A . 
     Unlike the antenna structure body  200  of  FIG. 11A , in the antenna structure body  200  of  FIG. 11B , a rear case area that supports the antenna structure body  200  does not exist. When the antenna structure body  200  is made of a flexible type material and when the strength reinforcing member  250  does not exist, the antenna structure body  200  may be lifted by the damping contact member  400  or may be pulled by the magnetic body  500 . Therefore, the electronic device  100  further includes a strength reinforcing member  250 , thereby preventing the antenna structure body  200  from being damaged. When the antenna structure body  200  is made of a hard type (e.g., injection, metal, plating structure) material, the strength reinforcing member  250  may be omitted or may be included. 
     According to various exemplary embodiments, the strength reinforcing member  250  may be formed with a battery cover or back glass. For example, at least one of the antenna structure body  200  and the strength reinforcing member  250  may be mounted in a battery cover or back glass of the electronic device  100 . According to various exemplary embodiments, the strength reinforcing member  250  may be made of various materials, for example, it may be made of a material formed by injection of a synthesis resin such as plastic and may be made of a material such as glass or ceramic. 
       FIGS. 12A and 12B  are diagrams illustrating a comparison experimental value of an antenna performance before and after using the damping contact member  400  and the magnetic body  500  in the electronic device  100  according to an exemplary embodiment of the present disclosure. 
     A graph  1201  indicated by a solid line represents a Voltage Standing Wave Ratio (VSWR) measurement value, which is an antenna performance before applying the damping contact member  400  and the magnetic body  500  in the electronic device  100 , and a graph  1205  indicated by a dotted line represents a VSWR measurement value when applying the damping contact member  400  and the magnetic body  500  according to various exemplary embodiments of the present disclosure. Such an experiment graph enables to determine whether an antenna performance is deteriorated when the magnetic body  500  contacts with the damping contact member  400 . 
     As shown in  FIGS. 12A and 12B , even if the magnetic body  500  contacts with the damping contact member  400  according to various exemplary embodiments of the present disclosure, it may be determined through a graph and a numerical value that little difference exists in an antenna performance. That is, by using the damping contact member  400  and the magnetic body  500  according to various exemplary embodiments of the present disclosure, while maintaining an antenna performance, peripheral components can be prevented from being damaged and a damper function can be stably provided. 
       FIGS. 13A and 13B  are diagrams illustrating a coupling structure of the connection member  400  and the magnetic body  500  according to an exemplary embodiment of the present disclosure. 
     As shown in  FIG. 13A , according to an exemplary embodiment, in the electronic device  100 , the rear case  170  and the antenna structure body  200  are coupled according to an assembly process, and the first portion  410  of the damping contact member  400  may be fixed to a terminal of the antenna structure body  200  by soldering. Further, the magnetic body  500  may be mounted in the PCB  300 . In this case, the magnetic body  500  may be fixed to the PCB  300  by soldering. The second portion  450  of the damping contact member  400  may be inclined in an opposite direction of the first portion  410  in a state connected to the first portion  410 . According to various exemplary embodiments, according to a level of a coupling force of the first portion  410  and the second portion  450 , the second portion  450  is not inclined to a lower portion but is fixed to the first portion  410  to maintain a shape “Z”. 
     As shown in  FIG. 13B , a coupling member of the rear case  170 , the antenna structure body  200 , and the first portion  410  and a coupling member of the second portion  450 , the magnetic body  500 , and the PCB  300  may be coupled. In this case, the rotatable second portion  450  may rotate toward the first portion  410 . Further, the second portion  450  may be limited from rotating to the first portion  410  to a predetermined level by the stopper  415 . 
     As described above, as the second portion  450  connected to rotate relative to the first portion  410  is pulled by the magnetic body  500 , the damping contact member  400  may connect the PCB  300  and an electronic component (the antenna structure body  200 ). Thereby, the damping contact member  400  supports a stable damper function and can minimize damage of an electronic component connected to a connection member by minimizing a repulsive force of the connection member. 
     As described above, an electronic device according to various exemplary embodiments of the present disclosure minimizes a repulsive force of a connection member through a combination of a magnetic body and the connection member, thereby minimizing damage from occurring in an electronic component connected to the connection member. 
     Further, while minimizing a repulsive force of a connection member through a magnetic body and a connection member according to various exemplary embodiments of the present disclosure, a damper function can be efficiently performed. 
     Although exemplary embodiments of the present disclosure have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein described, which may appear to those skilled in the art, will still fall within the spirit and scope of the exemplary embodiments of the present disclosure as defined in the appended claims.
