  A method for assembling the foldable portable terminal described in Patent Document 1 will be described. Hereinafter, a case where the mobile terminal is a mobile phone will be described as an example. 10 and 11 are explanatory views showing an example of an assembly procedure of the folding cellular phone (hereinafter referred to as a specific example 1).

  Generally, a foldable mobile phone includes a key button side casing including a key operation unit and a display side casing including a liquid crystal display unit, and the key button side casing and the display side casing are interposed via a hinge unit. Connected. In the first specific example, in the key button side front case 82 constituting a part of the key button side casing, the cylindrical shape part 801 constituting a part of the hinge portion in a region facing the display side casing. Is formed. In addition, in the display-side front cage 81 that constitutes a part of the display-side casing, two cylindrical-shaped portions 802 that constitute another part of the hinge portion in a region facing the key button-side casing. , 803 are formed.

  Further, the cylindrical shape portion 801 on the key button side and the cylindrical shape portions 802 and 803 on the display side do not face each other in a state where the key button side case and the display side case are combined. Formed in position. Then, the key button side casing and the display side casing are combined in such a manner that the key button side cylindrical shape portion 801 is sandwiched between the two cylindrical shape portions 802 and 803 on the display side. By being configured in such a manner, in the first specific example, the hinge portion is configured in a manner in which the heel is divided into three parts in appearance. Hereinafter, the configuration method of the hinge portion configured in such a manner that it is divided into three parts in appearance is referred to as a three-division method.

  In the first specific example, as illustrated in FIG. 10A, a slit 821 is provided so as to be engaged with the cylindrical portion 801 of the key button side front case 82. Further, as shown in FIG. 10B, a key button side substrate 86 is incorporated in the key button side front case 82, and a flexible substrate 851 for connection to the key button side substrate 86 is connected to the display side substrate 85. Keep it. Then, the connector portion 852 of the flexible printed circuit board 851 is moved from the back side of the key button side front case 82 (the side opposite to the side where the key operation unit is provided) in the X direction shown in FIG. ) Through the slit 821, as shown in FIG. 11A, the key button side substrate 86 is connected.

  Next, as shown in FIG. 11A, the display-side front case 81 is attached to the key button-side front case 82 to which the substrate is attached. In this case, the two cylindrical portions 802 and 803 formed on the display-side front case 81 are combined so as to sandwich the cylindrical portion 801 formed on the key button-side front case 82. Then, the hinge unit 83 and the support 84 are attached to the combined cylindrical shape portions 801, 802, and 803.

  Next, the cellular phone is once folded, and the display side rear cover 88 and the key button side rear cover 87 are attached as shown in FIG. The display-side rear cover 88 is formed with a wall portion 881 so as to cover the hinge unit 83 and the support 84 in a state where the display-side rear cover 88 is attached to the mobile phone. Therefore, when the display-side rear cover 88 is attached to the mobile phone, the hinge unit 83 and the support 84 are fixed so as not to fall out of the hinge portion.

  As described above, the foldable mobile phone shown in the first specific example is assembled according to the procedure shown in FIGS.

  12 and 13 are explanatory diagrams showing another example of the procedure for assembling the foldable mobile phone (hereinafter referred to as specific example 2). Note that the mobile phone shown in the second specific example includes a three-part hinge structure as in the first specific example. In the second specific example, as in the first specific example, the key button side front case 91 is provided with a cylindrical shape portion 901, and the display side front case 92 is provided with two cylindrical shape portions 902 and 903. The two cylindrical shapes 902 and 903 on the display side are combined in such a manner as to sandwich the cylindrical shape portion 901 on the key button side.

  In the second specific example, as shown in FIGS. 12 and 13, a slit 921 is provided from one end of the cylindrical portion 901 of the key button side front case 92 toward the center. Also, as shown in FIG. 12, a key button side board 96 is incorporated in the key button side front case 92, and a flexible printed board 951 for connection to the key button side board 96 is connected to the display side board 95. . Then, the flexible printed circuit board 951 is slid from the side (in the Y direction shown in FIG. 12) with respect to the housing, and is passed through the slit 921 of the key button side front case 92, as shown in FIG. The connector portion 952 is connected to the key button side substrate 96. Then, the hinge unit 93 and the support 94 are inserted into the hinge cylinder portion of the key button side front case 92.

  Next, as shown in FIG. 13, the display side front case 91 is attached to the key button side front case 92 to which the substrate is attached. In this case, the two cylindrical shapes 902 and 903 formed on the display-side front case 91 are combined so as to sandwich the cylindrical shape 901 formed on the key button-side front case 92.

  Next, the bracket 910 is attached so as to cover the combined cylindrical shape portions 901, 902, and 903, and the bracket 910 and the display-side front case 91 are fastened together with screws 9100. The display-side front case 91 is formed with a wall portion 912 so as to cover the hinge unit 93 and the support 94 in a state where the display-side front case 91 is attached to the mobile phone. Therefore, when the display-side front case 91 is attached to the mobile phone, the hinge unit 93 and the support 94 are fixed so as not to fall out of the hinge portion.

  In the mobile phone shown in the specific example 2, a display-side rear cover and a key button-side rear cover are further attached, but are not shown in FIGS. 12 and 13.

  As shown in specific example 1 and specific example 2, in a foldable mobile phone in which a so-called hinge portion is configured in a three-division method, first, either the key button side or the display type internal mounting substrate is used as a casing. Include. Next, the flexible printed circuit board portion of the other substrate is passed through the slit or hole of the housing, and then connected to the substrate already incorporated in the housing with a connector or the like. Then, it is necessary to assemble the hinge unit and the support after aligning the two hinge cylindrical portions of the housing.

  In the assembling methods shown in specific example 1 and specific example 2, the operation of passing the flexible board through the slit provided in the front case or the like of the housing is complicated, and the difficulty of the assembling operation is high. In addition, since the flexible substrate must be passed through a narrow slit, the flexible printed circuit board portion is easily damaged. Also, since one of the board on the key operation unit side and the board on the display side is built into the front case of the housing and then the other board is built in to connect the boards together, the panel before each board is built into the housing Inspection (combination operation test) in a state where (boards) are connected to each other cannot be performed.

  Further, in the case of the configuration as in the first specific example, after the board is connected to the slit 821 of the key button side front case 82 through the connector portion 852, the display side front case 81, the hinge unit 83, and the support 84 are assembled. For this reason, it is unstable for an operator to hold the display-side front case 81, the hinge unit 83, and the support 84 with both hands, and the workability is poor and the assembly work is laborious.

  In the case of the configuration as in the second specific example, the key button side board 96 is not first assembled in the key button side front case 92, but the display side board 95 and the key button side board 96 are connected first. It is possible to keep it. However, before attaching the rear case, the hinge unit 93 and the support 94 must first be attached to the cylindrical shape portion of the hinge. For this reason, the display-side front case 91 and the key button-side front case 92 cannot be assembled to prepare a front case subassembly in advance.

  Further, in the case of the configuration as in the second specific example, even if the display side substrate 95 and the key button side substrate 96 are connected to each other before being incorporated in the front case, the portion of the flexible printed circuit board 951 is placed on the side. Must slide through a narrow slit 921. Therefore, workability is still poor, and labor is required for assembling work.

  In the foldable portable terminal described in Patent Document 2, the applicant is able to insert the flexible substrate with the slit portions provided in the shaft member and the bearing member aligned in the same straight line, thereby improving workability. Has been improved to some extent. However, since a shaft member and a bearing member are required, there is room for improvement in that the number of parts increases. In addition, when considering the load on the internal substrate, the position of the slit portion must be arranged so that the mobile terminal is aligned in a straight line with a slight bend, and there is room for improvement in terms of workability. I can say that.

  Therefore, the present invention can improve the workability at the time of assembling work, prevent damage to the flexible printed circuit board part, and increase the inspection efficiency, the mobile terminal hinge structure, the mobile terminal, and the mobile terminal manufacturing It aims to provide a method.

The first cutout portion is provided, and the second cutout portion is provided in the second cylindrical shape portion. Further, the first cutout portion and the second cutout portion are configured to be located on the same side surface in a state where the mobile terminal is opened. With such a configuration, when the mobile terminal is opened, the notches overlap each other and an opening through which the flexible printed board can be passed is formed. Therefore, the workability at the time of assembling work can be improved, the flexible printed circuit board portion can be prevented from being damaged, and the inspection efficiency can be increased.

  For example, in the conventional portable terminal, the assembly work is performed by providing a slit in a part of the casing component and passing the flexible printed board through the slit, so that the work is complicated and the flexible printed board is hooked. It was easy to break. On the other hand, according to the present invention, since the opening can be formed with the portable terminal opened, the portable terminal is placed on the table with the portable terminal opened, and the flexible printed circuit board is dropped thereon. A portable terminal can be assembled only by attaching in such a mode. Therefore, it is possible to eliminate the work of passing the flexible printed board through a narrow slit, to improve the workability during the assembly work and to prevent the flexible printed circuit board from being damaged.

  In addition, according to the present invention, a cylindrical support component to be attached in a state of being inserted into the hinge portion is provided, the third cutout portion is provided in the support component, and the third cutout portion is a mobile terminal. If it is configured to be located on the same side as the surface on which the first cutout portion and the second cutout portion are provided in a state in which the first cutout portion and the second cutout portion are provided, it can contribute to the slimming down of the mobile terminal. This can contribute to the reduction in size and weight of mobile terminals.

  For example, when two hinge units are used for the hinge portion of the portable terminal, the notch portion cannot be provided in the hinge unit, so that the path in which the flexible printed circuit board is stored passes through the substantially central portion of the hinge portion. Will form. Therefore, it is necessary to secure the length of the hinge part so as to secure at least the length of two hinge units and the length of the path of the flexible printed circuit board. On the other hand, according to the present invention, by forming a notch in the support component using a support component that is hollow inside, the path of the flexible printed circuit board can be formed so as to cover the support component. Compared with the case where two hinge units are used, the length of the hinge portion can be shortened. Therefore, it can contribute to the downsizing of the mobile terminal and can contribute to the reduction in size and weight of the mobile terminal.

  According to the present invention, the first cylindrical shape portion is formed so as to be located outside the wall portion of the first casing portion, and the second cylindrical shape portion is defined as the second casing portion. If it is configured to be positioned outside the wall portion, the hinge portion can be configured to be positioned outside the wall portion of the housing. Therefore, the workability during the assembly work can be improved without impairing the design.

  For example, in a conventional mobile terminal, the hinge portion is located on the inner side of the wall portion of each housing portion. Therefore, if an opening is provided in the wall portion of each housing portion, the state becomes visible from the outside. Therefore, in the conventional portable terminal, the opening part for letting a flexible printed board pass cannot be provided in the wall part of each housing | casing part. On the other hand, according to the present invention, since the hinge part is located inside the wall part of each casing part, the flexible printed circuit board is passed through the wall part of each casing part so that it cannot be visually recognized from the outside. A series of paths for passing the flexible printed circuit board from the opening provided in the wall portion of each housing portion to the opening formed by overlapping each notch portion. Can be formed. Therefore, it is possible to assemble the mobile terminal simply by placing it on the table with the mobile terminal open, and then mounting it in the manner of dropping the flexible printed circuit board from it. Can be improved.

It is a unit part for generating. The hinge unit 3 is a substantially cylindrical part, and includes a spring, a ball-shaped part made of metal, and a casing part made of metal or synthetic resin. For example, if the mobile phone 100 is simply rotatable via the hinge portion 120, the degree of fixation when the mobile phone 100 is fully opened or closed is weak. Further, when the user opens / closes the cellular phone 100, the user cannot feel whether the mobile phone 100 is fully opened or closed.

  As shown in FIG. 2, by using the hinge unit 3 for the hinge portion 120, a click force (latch force) is generated when the mobile phone 100 is fully opened or completely closed. It is possible to realize that the user is fully opened or closed. In addition, the degree of fixation when the cellular phone 100 is in a fully opened state or a closed state can be increased.

  The support 4 supports the cylindrical shape portion 201 of the display side front case 1 and the cylindrical shape portion 203 of the key button operation side front case 2 and supports the rotational movement via the hinge portion 120. It is a part. The support 4 is a cylindrical part and is manufactured using a metal or a synthetic resin material.

  The support 4 is accommodated in the hinge cylindrical shape portion 203 of the key button side front case 2. The length of the support 4 is longer than the length of the cylindrical portion 203 of the key button operation side front case 2. Therefore, when the support 4 is inserted from the cylindrical shape portion 203 side of the key button operation side front case 2, the front end portion of the support 4 on the notch portion 41 side reaches the hinge cylindrical shape portion 201 of the display side front case 1. Mounted to reach the protruding position. By being attached in such a manner, the cylindrical shape portion 201 of the display side front case 1 and the cylindrical shape portion 203 of the key button operation side front case 2 are fixed by the support 4, and the housing of the support 4 is not displaced from each other. To play a supporting role.

  Similarly, the length of the hinge unit 3 is longer than the length of the cylindrical portion 202 of the key button operation side front case 2. Therefore, when the hinge unit 3 is inserted from the cylindrical shape portion 202 side of the key button operation side front case 2, the distal end portion of the hinge unit 3 reaches a position protruding to the cylindrical shape portion 201 of the display side front case 1. And attached in a state of being fitted into the concave shape portion 210. By being attached in this manner, the cylindrical unit 201 of the display-side front case 1 and the cylindrical unit 202 of the key button operation-side front case 2 are fixed by the hinge unit 3, and the hinge unit 3 is configured so that the casings are It plays the role of supporting not to slip.

  Moreover, as shown in FIG. 3, the hinge cylindrical shape part 201 of the display side front case 1 is provided with the notch part 11 from which a part of the cylindrical shape is cut off. In addition, the hinge cylindrical shape portion 203 of the key button side front case 2 is provided with a cutout portion 21 in which a part of the cylindrical shape is cut off. The support 4 is also provided with a notch 41 in which a part of the cylindrical shape is cut off.

It is formed to be located. Note that the cut-out portion 11 on the display side and the cut-out portion 21 on the key button operation side are located on different surfaces when the mobile phone 100 is closed.

  Further, the side wall 1a of the display-side front case 1 is provided with an opening 1b through which a flexible printed board 51 (see FIG. 4) for connecting an internal mounting board is passed. In addition, an opening 2 b through which the flexible printed circuit board 51 is passed is provided in the side wall 2 a of the key button operation side front case 2.

  As already described, the mobile phone 100 is configured such that the hinge portion 120 is positioned outside the side wall 1a of the display-side front case 1 and the side wall 2a of the key button operation-side front case 2. The opening 1b provided in 1a and the opening 2b provided in the side wall 2a are in a state in which the mobile phone 100 is assembled (all front cases 1 and 2 and all rear covers 7 and 8 are attached). Therefore, it is hidden behind the hinge part 120 and cannot be visually recognized.

  Further, as shown in FIG. 3, in the side wall 1 a of the display-side front case 1, a region that is in contact with the cylindrical shape portions 202 and 203 in a state where the display-side housing 102 and the key button-side housing 112 are connected. 1c is formed in the shape curved inward (curved shape). In other words, when the side wall 1a of the display-side front case 1 is viewed in a cross section cut in the longitudinal direction, the region 1c is formed in a shape curved in an arc shape on the inside. Therefore, when the display-side housing 102 and the key button-side housing 112 are connected, the side wall 1a of the display-side front case 1 and the cylindrical shape portions 202 and 203 do not interfere with each other. Can be.

  Further, as shown in FIG. 3, in the side wall 2 a of the key button operation side front case 2, a region 2 c that comes into contact with the cylindrical portion 201 in a state where the display side case 102 and the key button side case 112 are connected. However, it is formed in an inwardly curved shape. In other words, when the key button operation side front case 2 is viewed in a cross section cut in the longitudinal direction, the region 2c is formed in a shape curved in an arc shape on the inside. Therefore, when the display-side housing 102 and the key button-side housing 112 are connected, the side wall 2a of the key button operation-side front case 2 and the cylindrical portion 201 do not interfere with each other. Can be.

  Next, an internal mounting board mounted on the mobile phone 100 will be described. FIG. 4 is a diagram showing a housing internal mounting board mounted on the mobile phone 100. As shown in FIG. 4, the foldable mobile phone 100 includes a display side substrate 5 mounted on the display side housing 102 and a key button side substrate 6 mounted on the key button side housing 112. In addition, a flexible printed circuit board 51 and a connector portion 52 are connected to the display side substrate 5 in advance. In the present embodiment, the connector portion 52 of the display side substrate 5 is further connected to the key button side substrate 6 so that the display side substrate 5 and the key button side substrate 6 are connected.

  Note that the flexible printed circuit board 51 and the display-side board 5 may be connected in advance by connector connection, or may be connected in advance by ACF connection or the like. Further, the flexible printed circuit board 51 and the display side substrate 5 may be integrally configured in advance by adopting a rigid flexible structure or the like.

  In the present embodiment, the flexible printed circuit board 51 is connected in advance to the display side circuit board 5 side, but conversely, the flexible printed circuit board 51 is connected first to the key button side circuit board 6 side. After that, the display side substrate 5 may be connected.

  In this embodiment, as will be described later, after the display side substrate 5 and the key button side substrate 6 are connected in advance to assemble the subassembly of the substrate, the subassembly of the substrate is connected to the subassembly of the front case. It is configured to be combined.

  FIG. 5 is an exploded perspective view showing a state where the key button side rear cover 7 and the display side rear cover 8 are removed from the mobile phone 100. As shown in FIG. 5, the key button side rear cover 7 is formed with a covering portion 7 a that covers a part of the hinge portion 120. In FIG. 5, only one covering portion 7a is shown, but the key button side rear cover 7 has two covering portions so as to overlap the cylindrical shape portions 202 and 203 of the key button operation side front case 2. 7a is formed.

  The covering portion 7a is formed so as to cover the notch portion 21 provided in the cylindrical shape portion 203 in a state where the key button operation side front case 2 and the key button side rear cover 7 are combined.

  In addition, the display-side rear cover 8 is formed with a covering portion 8 a that covers a part of the hinge portion 120. The display-side rear cover 8 is formed with a cover portion 8a so as to cover the surface of the cylindrical-shaped portion 201 of the display-side front case 1 on which the cutout portion 11 is formed.

  The covering portion 8a is formed so as to cover the cutout portion 11 provided in the tubular shape portion 201 in a state where the display side front case 1 and the display side rear cover 8 are combined.

  In addition, slits 22 for fixing to the key button side rear cover 7 are respectively provided in the cylindrical shape portions 202 and 203 of the key button operation side front case 2. In addition, a protrusion 71 for fixing to the key button operation side front case 2 is formed on the covering portion 7 a of the key button side rear cover 7. In FIG. 5, only one protrusion 71 is shown, but the key button-side rear cover 7 has protrusions 71 formed on the two covering parts 7a. The key button side rear cover 7 is fixed to the key button operation side front case 2 by fitting the protrusions 71 formed on the covering portion 7a into the slits 22 provided in the cylindrical portions 202 and 203, respectively.

  FIG. 6 is a cross-sectional view showing the hinge portion 120 of the mobile phone 100 by cutting. 6 corresponds to a cross-sectional view (AA cross-sectional view shown in FIG. 2) in which the hinge portion 120 of the mobile phone 100 is cut in the longitudinal direction. As shown in FIG. 6, predetermined covering parts (hereinafter referred to as caps) 9a and 9b are attached to the hinge unit 3 and the support 4, respectively.

  In FIG. 5, the height of the protruding portion 71 formed on the covering portion 7 a of the key button side rear cover 7 is higher than the thickness of the cylindrical portions of the cylindrical shape portions 202 and 203. Therefore, when the protruding portion 71 is fitted into the slit 22 provided in the cylindrical shape portions 202 and 203, the tip portion of the protruding portion 71 protrudes inside the cylindrical shape portions 202 and 203 as shown in FIG. It becomes a state.

  As shown in FIG. 6, a groove portion 43 (see FIG. 3) is formed in the cap 9 b attached to the support 4. Therefore, when the projection 71 is fitted with the support 4 attached, the tip of the projection 71 is fitted in the groove 43 of the cap 9 b and the support 4 is fixed to the hinge portion 120. Accordingly, the protrusion 71 and the slit 22 also serve to fix the support 4 to the hinge portion 120.

  Similarly, as shown in FIG. 6, a groove portion 33 is formed in the cap 9 a attached to the hinge unit 3. Therefore, when the projection 71 is fitted with the hinge unit 3 attached, the tip of the projection 71 is fitted in the groove 33 of the cap 9a, and the hinge unit 3 is fixed to the hinge 120. Therefore, the protrusion 71 and the slit 22 also serve to fix the hinge unit 3 to the hinge 120.

  Next, a procedure for assembling the foldable mobile phone 100 will be described. FIG. 7 is a flowchart showing the procedure for assembling the foldable mobile phone 100. In the present embodiment, mobile phone 100 is assembled, for example, by a manual assembly operation by an operator. For example, the mobile phone 100 is assembled by an assembly device or an assembly robot that operates by program control.

  First, the display-side front case 1 is manufactured so as to form the cylindrical shape portion 201 provided with the notches 11 in advance when manufacturing housing parts such as each front case and each rear case. Further, the key button operation side front case 2 is manufactured so as to form the cylindrical shape portion 203 provided with the cylindrical shape portion 202 and the cutout portion 21 in advance.

  Further, as shown in FIG. 2, the display-side front case 1 and the key button operation-side front case 2 are combined in such a manner that the cylindrical shape portion 201 is sandwiched between the cylindrical shape portions 202 and 203. Also, as shown in FIGS. 2 and 3, the hinge unit 3 and the support 4 are assembled by being fitted into the cylindrical portions 201, 202, and 203, respectively (step S1). In this way, the display side front case 1, the key button operation side front case 2, the hinge unit 3 and the support 4 assembled are referred to as a front case subassembly.

  Next, as shown in FIG. 4, the display side substrate 5 and the key button side substrate 6 are connected via the connector portion 52 and the flexible printed circuit board 51 (step S2). The state in which the display side substrate 5 and the key button side substrate 6 are connected in this manner is called a substrate subassembly.

  By the above assembling operation or assembling process, two of the sub-assembly of the front case of the housing and the sub-assembly of the substrate are produced.

  Next, as shown in FIG. 8, the substrate subassembly assembled in step S2 is attached to the front case subassembly assembled in step S1 (step S3). In this case, as shown in FIG. 8, with the front case sub-assembly open, the sub-assembly of the substrate from the back side (the side that cannot be seen when the cellular phone 100 is assembled). Is attached (in the Z direction shown in FIG. 8).

  As already described, the notches 11, 21, 41 are provided so as to be on the same surface side when the mobile phone 100 is opened (that is, the front case subassembly is opened). Openings 1b and 2b are provided in the side walls 1a and 2a of the front cases 1 and 2, respectively. Therefore, as shown in FIG. 9, when the sub-assembly of the front case is opened, the flexible printed circuit board 51 is passed from the inside of the display side front case 1 to the inside of the key button operation side front case 2 on the back side. The path is formed. Therefore, the flexible printed circuit board 51 can be attached to the cylindrical shape parts 201, 202, and 203 constituting the hinge part 120 only by attaching the board subassembly in a state in which the front case subassembly is opened. It can be attached in a state of being housed in the housing.

  In step S3, the flexible printed circuit board 51 is connected to the cylindrical shape portions 201, 202, through the openings formed by the cutout portions 11, 21, 41 overlapping each other with the cellular phone 100 opened. It is stored inside 203.

  Next, as shown in FIG. 5, the sub-assembly of the front case to which the internal mounting board is attached in step S3 is temporarily folded (step S4). Then, the key button side rear cover 7 and the display side rear cover 8 are fitted in the folded state, thereby completing the assembly of the casing of the mobile phone 100 (step S5).

  In step S5, as shown in the cross-sectional view of FIG. 6, the protrusion 71 formed on the key button side rear cover 7 is provided with the slit 22 provided in the cylindrical shape portions 202 and 203 of the key button side front case 2. Are inserted respectively. In this case, the protruding portion 71 is also inserted into the groove portions 33 and 43 of the caps 9a and 9b via the cylindrical shape portions 202 and 203. In such a state, the caps 9a and 9b serve as a blindfold inside the hinge portion 120, and also serve as a retaining unit for the hinge unit 3 and the support 4.

  As described above, according to the present embodiment, the display-side front case 1, the key button operation-side front case 2, and the support 4 are provided with the notches 11, 21, and 41, respectively. In addition, each of the cutout portions 11, 21, 41 is provided so as to be positioned on the same side surface when the mobile phone 100 is open. Therefore, when the cellular phone 100 is in an open state, the notches 11, 21, 41 overlap each other, and an opening through which the flexible printed board 51 can be passed is formed.

  Moreover, according to this Embodiment, each cylindrical shape part 201,202,203 is formed so that it may be located in the outer side of the side walls 1a, 2a of each front case 1, 2, and the hinge part 120 is the side walls 1a, 2a. It is formed so that it may be located outside. Therefore, openings 1b and 2b for allowing the flexible printed circuit board 51 to pass through can be provided on the side walls 1a and 2a of the front cases 1 and 2 so that they cannot be seen from the outside.

  According to the present embodiment, the mobile phone 100 can be simply installed by placing the front case sub-assembly on the table with the back side up and dropping the substrate sub-assembly from the front case. The mobile phone 100 can be easily assembled. Therefore, the work of passing the flexible printed circuit board 51 through the slit of the housing becomes unnecessary, and the workability at the time of assembling the mobile phone 100 is improved.

  Further, according to the present embodiment, it is not necessary to perform the operation of passing the flexible printed circuit board 51 through the slit of the housing. Therefore, it is possible to prevent a situation such as the flexible printed circuit board 51 being caught by the slit and being damaged, Damage to the flexible printed circuit board 51 during assembly work can be prevented.

  In addition, according to the present embodiment, the display side substrate 5 and the key button side substrate 6 are first connected to produce a subassembly of the substrate, and then assembled in such a manner that it is dropped into the subassembly of the front case as it is. Work can be done. For example, as shown in FIGS. 10 to 13, in general, in a three-fold type folding mobile phone, the display side substrate and the key button side substrate must be connected after passing through a slit provided in the housing. The sub-assembly of the substrate cannot be assembled by connecting the display side substrate and the key button side substrate in advance. Therefore, in general, inspection such as a combined operation test of the substrates cannot be performed in a state where the display-side substrate and the key button-side substrate are connected and the sub-assembly of the substrate is assembled.

  On the other hand, according to the present embodiment, since the sub-assembly of the substrate can be manufactured before being incorporated into the housing, the operation test of the substrate or the like can be performed with the display side substrate 5 and the key button side substrate 6 combined. Inspection can be performed and inspection efficiency can be improved. In addition, since a combination operation test or the like can be performed in a state in which the substrates are integrated, the reliability of the product can be improved as compared with the case where the display side substrate 5 and the key button side substrate 6 are inspected alone. .

  From the above, according to the present embodiment, it is possible to improve workability during assembly work, prevent damage to the flexible printed circuit board portion, and increase inspection efficiency.

  For example, in general, in a foldable mobile phone, it is desirable that the hinge unit 120 is configured in a manner that is divided by the smallest possible number of appearances from the viewpoint of design. For this reason, in consideration of technical restrictions, it is preferable from the viewpoint of design that the hinge portion is configured in about three divisions, and the degree of freedom in design is improved.

  As shown in FIGS. 10 to 13, generally, a three-fold type folding mobile phone is configured such that the hinge portion is positioned inside the side wall of the housing. Then, since the side wall of the housing is visible from the outside, it is not possible to provide an opening for allowing the flexible substrate to pass therethrough. It cannot be mounted in such a manner that it is dropped. For this reason, as shown in FIGS. 10 to 13, it is necessary to provide a slit for passing the flexible printed board, and the workability is not good.

  In addition, in the mobile phone shown in FIGS. 10 to 13, it may be possible to attach the substrate in such a manner that the substrate is dropped as it is by opening part or all of the side wall of the housing. Therefore, it is necessary to attach a covering component for closing the opening of the side wall of the housing. For this reason, the number of parts increases and the design is impaired.

  In the present embodiment, the hinge portion 120 is configured to be located outside the side walls 1a and 2a of the housing, so that the side walls 1a and 2a on the side where the hinge portion 120 is configured cannot be seen from the outside. it can. For this reason, the cylindrical shaped portions 201 and 203 and the support 4 can be provided with notches 11, 21, and 41, and the openings 1b and 2b can be provided on the side walls 1a and 2a of the housing. A path for passing the flexible printed circuit board 51 can be formed on the back surface side. Therefore, it is possible to perform the assembling work in such a manner that the substrate subassembly is dropped as it is into the front case subassembly, and the workability can be improved without impairing the design.

  Further, in the mobile phone shown in FIGS. 10 to 13, the display substrate and the key button operation substrate must be connected after the flexible substrate is passed through the slit provided in the housing. Therefore, the display side board and the key button operation side board cannot be connected by a method such as soldering because the casing made of synthetic resin is damaged. In this embodiment mode, the substrate subassembly can be manufactured in advance before being attached to the housing by the above-described configuration. Therefore, there is no fear of damaging the casing, and it is also possible to connect the display side board and the key button operation side board by a method such as soldering, and the display side board and the key button operation side board can be connected more reliably. The connection can be made by the method, and the reliability can be improved.

  In the present embodiment, the hinge unit 3 and the support 4 are used to fix the cylindrical portions 201, 202, and 203 to form the hinge unit 120. However, the hinge unit is used instead of the support 4. Two hinges 3 may be used to form the hinge portion 120.

  However, in the present embodiment, it is possible to form the notch 41 in the support 4 by using the support 4 that is a cylindrical part. Therefore, the path in which the flexible printed circuit board 51 is accommodated can be formed in a mode close to the support 4 side, which is advantageous for making the mobile phone 100 thinner.

  For example, when two hinge units 3 are used, a cutout portion cannot be provided in the hinge unit 3, so a path for storing the flexible printed circuit board 51 is formed so as to pass through a substantially central portion of the hinge portion 120. Will do. Then, it is necessary to secure the length of the hinge portion 120 so as to secure at least the length of two hinge units 3 and the length of the path of the flexible printed circuit board 51.

  In the present embodiment, since the support 4 having a hollow shape is used, a cutout portion 41 can be formed to form a path of the flexible printed circuit board 51 so as to cover the support 4, and the hinge unit 3. Compared with the case where two are used, the length of the hinge part 120 can be shortened. Therefore, it is possible to contribute to the downsizing of the mobile phone 100, and it is possible to contribute to the reduction in size and weight of the mobile phone 100.

  The present invention can be suitably applied to a foldable mobile phone.
