Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority from and the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2013-0106797, filed on Sep. 5, 2013, which is incorporated by reference for all purposes as if fully set forth herein. 
     BACKGROUND 
     1. Field 
     The present disclosure relates to a component connection member, a mobile communication device comprising the same and a manufacturing method thereof, and more particularly, to a component connection member that may connect components disposed in different directions using a simple method, a mobile communication device comprising the same, and a manufacturing method thereof. 
     2. Discussion of the Background 
     When applying a metal case to a mobile communication device, communication by an antenna can be obstructed due to properties of the metal case. To overcome this problem, attempts have been made to use a metal case as a part of an antenna by applying an electric current to the metal case and the antenna. 
     Specifically,  FIG. 1  is a diagram illustrating a cross section of a mobile communication device  1  according to a related art. 
     Referring to  FIG. 1 , the mobile communication device  1  may have a case unit of the mobile communication device constructed by assembling a first case  21  and a second case  25 . A first antenna  23  is formed to be attached to an inner surface of the first case  21 , and the second case  25 , also referred to as a second antenna, made of a metal, may be used as a second antenna. 
     To connect the first antenna  23  to the second antenna  25 , many components need to be added, and the addition of components causes many problems such as high manufacturing costs, an increase in manufacturing cost per unit, an increase in procedural defect ratio, and the like. 
     More specifically, connection of the first antenna  23  to the second antenna  25  is established through a substrate  15 . For example, the substrate  15  and the first antenna  23  may be connected by a first clip  11 , and the second antenna  25  and the substrate  15  may be connected by a second clip  13 . Also, the first clip  11  and the second clip  13  are connected through a conductive pattern  12  connecting the first clip  11  and the second clip  13  along the side surface of the substrate  15 . 
     Particularly, in the connecting of the second antenna  25  disposed outside to the substrate  15  disposed inside, such connection is established by welding a nut  14  to the second antenna  25  or the second case, fitting a screw  19  into the nut  14 , and forming a frame structure  17  to connect the screw  19  to the second clip  13 . 
     During this process, because the conductive pattern  12 , the frame structure  17 , the screw  19 , and the nut  14  are added, additional mounting and assembly operations for each component need to be added. 
     Particularly, the addition of the nut  14  and the screw  19  creates many problems. The addition of the welding process of the nut  14  to the second case  25  results in a significant reduction in production yield. Also, when a defect occurs in the nut  14 , there is a drawback that the entire case should be discarded. A faulty tapping process of the nut  14  could lead to a screw fastening defect, and a position deviation of the nut  14  may result in the battery case on a product being loose. 
     Also, to tune this antenna pattern, a plurality of screws needs to be mounted, but as the number of screws increases, the defect ratio increases, and assembly process time, material costs, and manufacturing costs increase. 
     Furthermore, to form the conductive pattern  12  or after forming the frame structure  17 , a plating process needs to be additionally performed. However, the addition of the plating process increases component manufacturing cost per unit. Also, because the clips for overall contact may be damaged during substrate delivery, there is a disadvantage of having to add a separate case to protect the clips.

       FIG. 2  is a perspective view illustrating a component connection member  30  according to an exemplary embodiment of the present invention, and  FIG. 3  is a cross-sectional view illustrating the component connection member  30  according to the embodiment of  FIG. 2  in a mounted state in a mobile communication device  2 . 
     Referring to  FIGS. 2 and 3 , the component connection member  30  according to an exemplary embodiment includes a support structure  35 , and a first contact part  31  and a second contact part  33  connected to each end of the support structure  35 , respectively. The support structure  35  may be formed to have at least one bent part. Accordingly, the support structure  35  may connect components disposed in various directions. 
     As illustrated in  FIG. 3 , the component connection member  30  according to an exemplary embodiment is mounted on the substrate  15 . The component connection member includes the support structure  35  formed to have at least one bent part, the first contact part  31  connected to one end of the support structure  35  and formed to come into contact with and be electrically connected to a first component disposed facing a first surface A of the substrate, and the second contact part  33  connected to the other end of the support structure  35  and formed to come into contact with and be electrically connected to a second component disposed facing a second surface B adjacent to the first surface A of the substrate or a third surface C opposite to the first surface A of the substrate. 
     In particular, the support structure  35  according to an exemplary embodiment may be formed to connect the first component disposed facing the first surface A or any one surface formed on the substrate to the second component disposed facing the second surface B or the third surface C that is different in direction from the first surface A. Although the embodiments of  FIGS. 2 through 6  show the connection of components disposed in the first surface A direction and the second surface B direction adjacent thereto, and the embodiments of  FIGS. 7 through 9  show the connection of components disposed in the first surface A direction and the third surface C direction opposite thereto, the present disclosure is not necessarily limited thereto, and the support structure may be formed to have a bent part which is bent at various angles to connect components disposed in various directions. 
     Also, the support structure  35  may be disposed at the end portion of the substrate  15 , and may be disposed to be hung on the end as illustrated in  FIGS. 2 through 6  or may be placed on the end as illustrated in  FIGS. 7 through 9 . 
     Accordingly, the support structure  35  may be formed to connect components disposed in various directions at the end portion of the substrate  15 . 
     According to an exemplary embodiment, the first contact part  31  may be formed to come into contact with the first component disposed in the first surface A direction of the substrate  15 , and the second contact part  33  may be formed to come into contact with the second component disposed in the second surface B or the third surface C direction of the substrate  15 . 
     The first contact part  31  and the second contact part  33  may be made in a shape of a plate spring such that the first contact part  31  and the second contact part  33  are elastic against the first surface A and the second surface B or the third surface C, respectively. Accordingly, the contact may be more reliable. 
     As illustrated in  FIG. 2 , according to an exemplary embodiment, the support structure  35  may also include at least one fixing part  37  drawn from the support structure  35  and formed to be inserted into the substrate  15 . The fixing part  37  may not only serve to fix the support structure  35  to the substrate but also serve to electrically connect the support structure  35  to a component or circuit of the substrate  15 . Although the embodiment of  FIG. 2  shows two fixing parts  37  formed to be drawn out from the support structure  35 , the present disclosure is not necessarily limited thereto, and one or more fixing part(s) drawn out in different directions may be provided. 
     Although the present disclosure shows and describes that the component connection member connects, for example, a first antenna and a second antenna disposed in different directions in the mobile communication device, the present disclosure is not necessarily limited thereto, and various components disposed in different directions may be the first component and the second component. 
     Referring to  FIG. 3 , the component connection member  30  according to an exemplary embodiment of the present invention may be applied in the mobile communication device  2 . 
     A case of the mobile communication device  2  may be provided by assembling at least one case. In the exemplary embodiment of  FIG. 3 , the part disposed facing down in the drawing represents a display part which displays an image and the part disposed facing up represents a rear part where a battery or the like is disposed. 
     According to an exemplary embodiment, the mobile communication device  2  may be formed such that the first case  21  disposed on the rear surface is connected to the second case  25  disposed on the side surface directly or indirectly by the medium of another case. 
     The first case  21  may be formed to embed the first antenna  23  therein. The first case  21  may be formed, for example, by injection molding in a state in which the first antenna  23  is included in the inner surface of the first case  21 . But the method for forming the first case  21  with the first antenna embedded is not necessarily limited thereto, and the first case  21  may be formed to attach the first antenna  23  thereto in an inner surface of the device by various methods. 
     The second case  25  may be a side case formed to surround the mobile communication device  2 , and may be integrally formed to improve the strength of a product and the like. According to an exemplary embodiment, the second case  25  may be a side metal case formed to surround the side surface of the mobile communication device  2 . 
     When the second case  25  is formed in a metal case, the second case  25  may be used as a second antenna which may be connected to the first antenna  23  to improve the performance of the first antenna  23 . Accordingly, the second case  25  used as a second antenna, may be also referred to as a ‘second antenna’  25 . 
     The component connection member  30  may be used to connect the first antenna  23  formed in the first case  21  to the second antenna  25 . 
     One end of the support structure  35  may have a first support surface  39   a  which may be disposed on the first surface A of the substrate  15 . The first support surface  39   a  may be adhered on the surface of the substrate  15 . For example, the first support surface  39   a  may be welded, soldered, attached, fixed, or the like on the surface of the substrate  15 . Further, an adhesive, an adhesive tape, or the like may be disposed between the first support surface  39   a  and the one end of the support structure  35 . The other end of the support structure  35  may have a second support surface  39   b  which may be disposed in the second surface B direction. The first support surface  39   a  and the second support surface  39   b  may be connected by a bent part of the support structure  35 . 
     Although the embodiment of  FIG. 3  shows that only the first support surface  39   a  is adhered on the surface A of the substrate  15  and the second support surface  39   b  is not in a close contact with the second surface B, the present disclosure is not necessarily limited thereto, and both the first and second support surfaces  39   a  and  39   b  may be welded, soldered, attached, fixed, or the like, on different surfaces of the substrate  15 . Further, an adhesive, an adhesive tape, or the like may be disposed between both the first and second support surfaces  39   a  and  39   b  and different surfaces of the substrate  15 . 
     The first support surface  39   a  may be formed to be connected to the first contact part  31  to come into contact with the first antenna  23 . The second support surface  39   b  may be formed to be connected to the second contact part  33  to come into contact with the second antenna  25 . 
       FIG. 4  is an internal exploded perspective view illustrating an inside of a mobile communication device  3  in which the component connection member  30  according to an exemplary embodiment is mounted on the substrate  15 . 
     According to an exemplary embodiment, at least one component connection member  30  may be disposed at the end portion of the substrate  15 . The antenna characteristics may change based on a location of the substrate  15 , a contact location with the first antenna  23 , and a contact location with the second antenna  25 . 
     Accordingly, when assembling a mobile communication device, an antenna tuning operation is needed to adjust the contact locations. 
     In the embodiment of  FIG. 4 , considering the antenna characteristics, at least one component connection member  30  may be disposed at the end portion of the substrate  15  where the first antenna  23  and the second antenna  25  are connected, to allow a connection with the first antenna and a connection with the second antenna to be established at a desired location. 
     An antenna tuning operation may be performed by controlling a number of component connection members or a number of branches to be described later, or by adjusting a location of a component connection member or a branch to be connected, during antenna tuning. 
     For antenna tuning, to select a first contact part and a second contact part of a desired component connection member  30  and to connect them to the first antenna  23  or the second antenna  25 , first contact part(s) and second contact part(s) apart from those selected may be shorted or open. 
     More specifically, in the fixed component connection member, to allow only desired first and second contact parts to come into contact with the first antenna  23  or the second antenna  25  and to preclude the remaining first and second contact parts from coming into contact with the first antenna  23  or the second antenna  25 , antenna tuning may be performed by adjusting the contact location by, for example, bending, cutting, or interposing an insulation material. 
     During antenna tuning at the product development stage, as a number of essential factors affecting the tuning increases, the number of tuning tests increases. However, according to the exemplary embodiment, where only one component connection member is used to connect antennas, the number of essential factors affecting the antenna tuning reduces. Thus, tuning may be performed quickly in a simple and easy manner, and antenna performance may be ensured. 
     According to an exemplary embodiment, a tuning or testing operation may be performed within a very short time and performance may be ensured at an earlier time, compared to a conventional method such as screw clamping or the like. 
     According to an exemplary embodiment, the component connection member  30  may be mounted on the substrate by a surface mount technology (SMT), or may be manufactured as a component connection module which is formed to be assembled on the substrate. 
     More specifically, during the substrate processing, the substrate may be prepared in a state in which the component connection member  30  is pre-mounted on the substrate. Also, an electrical connection of the first antenna  23  and the second antenna  25  may be established by assembling the substrate  15  between the first case  21  and the second case  25 . Accordingly, the first antenna  23  and the second antenna  25  may be connected by a simple method without going through additional conventional processes to add components such as a screw, a nut, and a plating process of a conductive pattern. 
     Finally, according to an exemplary embodiment, manufacturing the mobile communication device may be implemented in a simple and easy manner, and due to the component connection member being prepared in a pre-mounted state, a defect ratio that occurs during an assembly process may be reduced. Also, because various components and a plating process or an assembly process does not need to be added, the product cost and the assembly cost may be reduced and the assembly time may also be shortened. 
       FIG. 5  is an exploded view illustrating a component connection module according to an exemplary embodiment of the present invention.  FIG. 6  is a cross-sectional view illustrating a cross section of a device  4  having the component connection module according to the embodiment of  FIG. 5  mounted therein. According to the exemplary embodiments of  FIGS. 5 and 6 , the component connection member may be formed to be assembled in a modular state and assembled on a substrate, but not mounted on a substrate. 
     As illustrated in  FIGS. 5 and 6 , according to an exemplary embodiment, the component connection module  30 ′ includes a housing  40  in which the support structure  35  is mounted on, and a drawn fixing part  38  (see  FIG. 6 ) connected to the support structure  35  and drawn outside the housing  40  to form a connection terminal to the substrate. 
     Accordingly, the component connection member  30 ′ may be provided in a state of a component connection module after being coupled with the housing  40 . The component connection module in a mounted state on the substrate  15  may be assembled between the first case  21  and the second case  25 , which may connect the first antenna  23  and the second antenna  25 . 
     Thus, as illustrated in  FIG. 5 , the component connection member  30 ′ may be mounted on the substrate  15  only by a process of assembling the component connection module on the substrate. When a product is provided in a modularized state, the mobility of the product may increase, and detachment and replacement of the product may be facilitated. 
     Meanwhile, the support structure  35  is formed by connecting at least one of branches  36   a ,  36   b ,  36   c ,  36   d , and  36   e  having at least one bent part. Each of the branches  36   a ,  36   b ,  36   c ,  36   d , and  36   e  may be formed to be connected to first contact parts  31   a ,  31   b ,  31   c ,  31   d , and  31   e  at one end and second contact parts  33   a ,  33   b ,  33   c ,  33   d , and  33   e  at the other end. 
     Because the component connection member is composed of a support structure  35  including the at least one branch  36   a ,  36   b ,  36   c ,  36   d , and  36   e  connected, a cumbersome task of attaching the component connection member to the substrate one by one may be avoided. Also, the component connection member including the support structure  35  composed of a plurality of branches may be also mounted on the substrate by a surface mount technology, and as shown in  FIG. 5 , may be provided in a type of a module after being mounted on the housing  40 . 
     Specifically, the component connection module includes the housing  40  for mounting the support structure  35  formed by connecting at least one of branches  36   a ,  36   b ,  36   c ,  36   d , and  36   e , in which the branches  36   a ,  36   b ,  36   c ,  36   d , and  36   e  include the first contact parts  31   a ,  31   b ,  31   c ,  31   d , and  31   e  and the second contact parts  33   a ,  33   b ,  33   c ,  33   d , and  33   e , respectively connected to each end, and at least one drawn fixing part  38   a ,  38   b ,  38   c ,  38   d , and  38   e  each connected to the branches  36   a ,  36   b ,  36   c ,  36   d , and  36   e  and drawn outside the housing to form a connection terminal to the substrate. 
     As illustrated in  FIG. 5 , according to an exemplary embodiment, the substrate  15  or the housing  40  may have a mounting hole H to include the support structure, the drawn fixing part, a portion of the first contact part, and a portion of the second contact part therein, and the housing  40  may be molded by an insert injection molding process or the like, in a state in which the housing  40  includes the component connection member inside. 
     According to an exemplary embodiment, the substrate  15  or the housing  40  may include the mounting hole H for mounting the support structure  35  to protect a portion of the first contact part  31  and a portion of the second contact part  33  within the housing  40 . 
     Although the embodiment of  FIG. 5  shows that the mounting hole H is disposed in the housing for modularization, the mounting hole H is not necessarily limited thereto and may be disposed at the end part of the substrate  15 . 
     When the component connection member is entirely exposed, there was a concern about damage of the connection member during component transfer or assembly with other component, however because the mounting hole H is formed to protect the support structure, a portion of the first contact part and a portion of the second contact part inside the hole H, damage of the component connection member that may occur during product delivery may be decreased. Also, a need for a separate case for protecting the component connection member is eliminated. 
       FIG. 7  is an internal exploded perspective view illustrating a component connection member according to an exemplary embodiment and an inside of a device  5  in which the connection member is assembled, and  FIG. 8  is an internal exploded perspective view illustrating a component connection member according to an exemplary embodiment and an inside of a device  6  in which the connection member is assembled. 
     The component connection members  50  and  70  according to the embodiments may include first support surfaces  59   a  and  79   a  which are disposed on the first surface A of the substrate  15 , second support surfaces  59   b  and  79   b  which are disposed on the third surface C opposite to the first surface A, and support structures  55  and  75  connecting the first support surfaces  59   a  and  79   a  and the second support surfaces  59   b  and  79   b . Also, the component connection members  50  and  70  may be formed to include first contact parts  51  and  71  connected to one end of the first support surfaces  59   a  and  79   a  and second contact parts  53  and  73  connected to one end of the second support surfaces  59   b  and  79   b.    
     The component connection members  50  and  70  according to the embodiments of  FIGS. 7 and 8  are formed such that the first support surfaces  59   a  and  79   a , the support structures  55  and  75 , and the second support surfaces  59   b  and  79   b  surround an end portion of the substrate, the end portion of the substrate  15  fitting into the component connection members  50  and  70 . Accordingly, the component connection members  50  and  70  may be assembled by a more simple and easy method. 
     For example, referring to  FIG. 7 , the first contact part  51  and the second contact part  53  may be connected to the first support surface  59   a  and the second support surface  59   b , and formed to extend along an end line L of the substrate  15 . Thus, when the component connection member  50  is placed on the end portion of the substrate, the first contact part  51  and the second contact part  53  may be disposed to extend along the end line L of the substrate. Accordingly, the component connection member  50  may be formed to be mounted on a narrow space at an edge of the substrate  15  (see  FIG. 9 ). 
     That is, according to the exemplary embodiment, in the design of the substrate  15 , the component connection member  50  that may connect the components by making use of the narrow space at the edge may be provided. Accordingly, the connection member  50  with high flexibility that may be applicable to various components may be provided. 
     Referring to  FIG. 8 , the first contact part  71  or the second contact part  73  may be connected to the first support surface  79   a  and the second support surface  79   b , and formed to extend in a direction crossing the end line L of the substrate  15 . Accordingly, the component connection member  70  may connect components formed at various locations near the substrate  15  as well as components formed near the end portion of the substrate  15 . 
     Although the embodiments of  FIGS. 7 and 8  show that both the first contact part and the second contact part are disposed in the same direction with respect to the substrate, the first contact part and the second contact part are not necessarily limited thereto, and any one of the first contact part and the second contact part may be disposed to extend along the end line L of the substrate  15  and the remaining contact part may extend in a direction crossing the end line L of the substrate  15 . 
       FIG. 9  is a cross-sectional view illustrating a state in which the component connection member  50  of  FIG. 7  is assembled in a device. 
     Referring to  FIG. 9 , in connecting the first antenna  23  disposed within the first case  21  to the second case  25 ′ or a metal side case, the component connection member  50  according to the embodiment of  FIG. 7  may be mounted on the substrate  15 . 
     Specifically, as illustrated in  FIG. 9 , the first case  21  may be a case which forms a rear surface of the device where the first antenna  23  is embedded or attached, while a display unit  27  is disposed facing down. 
     The second case  25 ′ may be, for example, a metal case which forms a side surface of the device. The first case  21  may be disposed in the first surface A direction of the substrate  15 , and the second case  25 ′ may further include a first frame  25   a  disposed in the second surface B direction adjacent to the first surface A of the substrate, and a second frame  25   b  extending from the first frame  25   a  toward the third surface C opposite to the first surface A. 
     Accordingly, the first case  21 , and the first frame  25   a  and the second frame  25   b  of the second case  25 ′ in a sequential order may form a ‘C-type’ or ‘symmetrical C-type’ structure. Although the exemplary embodiment as illustrated in  FIG. 9  shows an embodiment of forming a ‘symmetrical C-type’ structure, the present disclosure is not necessarily limited thereto, and placement may be made to have a ‘C-type’ structure. Thus, the first contact part  51  of the component connection member  50  may be connected to the first case  21  disposed in the first surface A direction, and the second contact part  53  may be connected to the second frame  25   b  of the second case  25 ′ disposed in the third surface C direction. 
     Particularly, with regard to the component connection member  50  of the exemplary embodiment in  FIG. 9 , due to it being capable of connecting the components even when mounted on a narrow space at the edge of the substrate, even if the second frame  25   b  has a short length extending in the third surface C direction, the second frame  25   b , also referred to as the second antenna  25 ′, may be connected to the first antenna  23 . Therefore, according to the exemplary embodiment, minimization of the device may be achieved by reducing a width between the component connection member  50  and an edge frame, the second frame  25   b , of the device. 
     If the second frame  25   b  is disposed in the third surface C direction, when utilized as a structure in which a display panel or a cover glass covering the display panel are disposed, such application may minimize the thickness of the device. In addition, because the first antenna  23  and the second antenna  25 ′ are connected by the component connection member  50 , a stable connection of the antennas may be ensured and signal loss may be minimized, and moreover, slimming and minimization of the device may be achieved by optimizing the component placement inside the device. 
     According to an exemplary embodiment, the component connection member which may connect components disposed in a vertical or horizontal direction may be provided. Thus, compared to a conventional structure where many complicated components need to be added to connect components, in the exemplary embodiment components may be connected by just one member, the component connection member. 
     Because the component connection member of the present disclosure may be provided in a unitary connected state, the strength of a product may be improved, the damage to components may be decreased, and component handling may be facilitated when compared to a structure where a plurality of components are connected. By simplifying a signal connection structure, signal loss may be minimized at each transmission step, and as a result, signal transmission efficiency and performance of the antenna may be improved. 
     Also, a method of manufacturing the mobile communication device according to an exemplary embodiment includes preparing the first case  21  in which the first antenna  23  is disposed in an inner surface of the device, the second case comprising the second antenna  25 , made of a metal and disposed in an outer surface of the device, and the substrate  15  disposed within the device, and mounting the at least one component connection member  30  on the substrate  15 , the component connection member  30  including the support structure  35  formed to have at least one bent part, the first contact part  31  connected to one end of the support structure  35  and formed to come into contact with and be electrically connected to the first antenna disposed facing the first surface A of the substrate, and the second contact part  33  connected to the other end of the support structure  35  and formed to come into contact with and be electrically connected to the second antenna  25  disposed facing the second surface B adjacent to the first surface A of the substrate or the third surface C opposite to the first surface A. 
     The mounting of the component connection member may include mounting the component connection member  30  on the substrate by a surface mount technology, or assembling as a component connection module. 
     To tune the first antenna  23  and the second antenna  25 , at least one component connection member selected among the at least one or more component connection members mounted on the substrate  15  may be shorted, and a remaining component connection member among the at least one or more component connection member may be open. 
     According to the method of manufacturing the mobile communication device according to the exemplary embodiment, because the component connection member may be mounted on the substrate by a surface mount technology or a modular technology, a mounting process may be simplified to a simple method and a defect ratio may be reduced. Thus, costs incurred by faulty products may be reduced. 
     The component connection member of the present disclosure may be disposed at a corresponding location to the antenna. For antenna tuning, at least one component connection member may be disposed, or a component connection member having a plurality of branches may be disposed. Also, tuning may be performed in a simple manner by only a process that causes each component connection member or each branch to be shorted or open. 
     It will be apparent to those skilled in the art that various modifications and variation can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
