Description

  The present invention relates to an electronic device in which a first housing and a second housing are connected so as to be openable / closable and pivotable by two axes.

Some conventional electronic devices ensure the strength of the housing by using an insert metal plate (see, for example, Patent Document 1). In such an electronic device, the connection cable for electrically connecting the first housing and the second housing is routed by being overlapped with the insert sheet metal inside the housing.
In addition, there is a conventional electronic device in which a first housing having a display unit and a second housing having an operation unit are connected so as to be openable and closable and relatively rotatable. In the electronic device having such a structure, since the hinge portion is rotated around a plurality of rotation axes, a twisting force acts on the connection line connecting the first housing and the second housing. Therefore, if a flexible substrate is used as a connection line between the housings, disconnection is likely to occur. Therefore, in an electronic device having such a structure, a flexible connection cable such as a coaxial cable is used as a connection line between housings (see, for example, Patent Document 2).

  As shown in FIGS. 4 and 6, an insert sheet metal 28, which is a sheet metal member, is attached to the inner space 24 of the upper casing 20 in the center in the thickness direction. The company is trying to make it thinner. A liquid crystal display plate 25 is provided on the inner side surface 281 of the insert metal plate 28 via a backlight unit 29 that illuminates the liquid crystal display plate 25 from behind, and a touch panel 26 is attached to the inner surface side of the liquid crystal display plate 25. Yes. A first circuit board 31 on which various electronic components are mounted is attached to the outer side surface 282 of the insert sheet metal 28.

As shown in FIGS. 6 and 7, the touch panel 26 and the first circuit board 31 that drives the touch panel 26 are flexible printed boards (hereinafter referred to as “FPC”) 32 that are connection lines. Connected.
The touch panel 26 side of the FPC 32 is connected to an end portion (end surface 261A) of the glass substrate 261, and the connection portion 321 is a hinge of the side portion 22 of the upper housing 20 in order to avoid an increase in size of the upper housing 20. Projecting outward from the lower side portion 222 of the portion 50 side. This portion is a boundary portion with the hinge portion 50, and a space can be secured without providing a space for the FPC 32. For this reason, the FPC 32 is once routed (folded back 322) from the internal space 24 that is a waterproof area to the space of the hinge part 50 that is a non-waterproof area, and then drawn into the internal space 24 of the upper housing 20 again. .
In the present embodiment, waterproof FPC 32 is used. This prevents the wiring itself of the FPC 32 arranged in the non-waterproof area from being broken.

The lower side portion 222 of the upper casing 20 is provided with an FPC insertion hole 223 having, for example, a rectangular cross section that communicates the inside and outside of the upper casing 20, and the FPC 32 is drawn into the internal space 24 from the FPC insertion hole 223. . At this time, in order to maintain the waterproof property of the internal space 24, the grommet 33 is attached to the FPC insertion hole 223.
The grommet 33 is formed of an elastic member such as resin or rubber, has a thickness and width larger than the height and width of the rectangular FPC insertion hole 223, and is pressed into the FPC insertion hole 223 to stop. A water-stopping portion 331 having a rectangular cross section to be drained, a flange portion 332 that protrudes outward from the water stop portion 331 to position the grommet 33, and a guide portion 333 that protrudes from the flange portion 332 to the hinge portion 50 side. Have. In the center of the grommet 33, a through hole 334 having a flat rectangular shape and a cross section smaller than the cross section of the FPC 32 is formed so as to penetrate the water stop portion 331, the flange portion 332, and the guide portion 333. The FPC 32 is press-fitted and penetrated.

  In addition, a flat support plate 323 having a high rigidity, such as metal, is attached to the FPC 32 so that the waterproof property is not impaired by bending the through hole 334 of the grommet 33 when the FPC 32 is bent. Is made to penetrate straight.

As shown in FIGS. 8 to 10, a cushioning member 60 made of a flexible material such as resin or rubber is provided at a corner portion on the hinge portion 50 side of the upper housing 20. The buffer member 60 includes a buffer portion 61 that protects the hinge portion 50 side end surface and side corners of the upper housing 20, and a mounting portion 62 that attaches the buffer member 60 to the upper housing 20.
The buffer portion 61 is provided with a protrusion 611 that protrudes toward the hinge portion 50 side. Therefore, when the buffer member 60 comes into contact with the hinge portion 50, the protrusion 611 of the buffer portion 61 comes into contact first to prevent the hinge portion 50 and the upper housing 20 from being damaged.

  The mounting portion 62 has a top plate 621 protruding toward the upper housing 20 and a vertical wall 622 in the thickness direction of the upper housing 20 and has an L-shaped cross section. On the inner surface of the vertical wall 622, there are a plurality of ribs 623 and 624 that protrude toward the upper housing 20 and are fitted into mounting recesses 35 provided in the upper housing 20 so that the cushioning member 60 is raised. It is attached to the housing 20.

  That is, the rib 623 is provided along the mounting direction of the buffer member 60 from the central portion in the thickness direction of the upper housing 20 on the second rotation shaft 52 side, and the rib 623 and the mounting recess 35 of the upper housing 20 are provided. The ribs 351 provided in are fitted. In addition, a rib 624 that protrudes from the end of the buffer member 60 toward the upper housing 20 is fitted into the gap 352 of the mounting recess 35.

Further, the recess 630 (see FIG. 10) of the buffer member 60 and the rib 631 (see FIG. 9) of the upper housing 20 are fitted, and the claws 632 and 633 of the buffer member 60 are hooked portions of the upper housing 20. 634 is fitted. Thereby, the buffer member 60 is attached to the upper housing 20.
In addition, since the recessed part 630, the rib 631, the nail | claw 632,633, and the nail | claw fitting part 634 are provided along the attachment direction of the buffer member 60 with respect to the upper housing | casing 20, the recessed part 630, the rib 631, the nail | claw 632,633, The claw fitting portion 634 can also be used for positioning when the buffer member 60 is attached to the upper housing 20.

The top plate 621, the vertical wall 622, and the ribs 623 and 624 form a surrounding portion 63 that surrounds the folded portion 322 of the FPC 32 from the radial direction of folded axis lines 641 and 642 to be described later.
Note that a gap 625 between the top plate 621 and the rib 623 is wider than the rib 351. This is because if the gap 625 is narrowed, the gap 625 is also fitted with the rib 351, and a large force is required when the buffer member 60 is pushed.

As shown in FIG. 6, the folded portion 322 of the FPC 32 is bent in a semicircular shape when the FPC 32 is arranged (indicated by a broken line in FIG. 6). Then, the buffer member 60 is attached to the lower housing 40 from the hinge portion 50 side (in the direction of arrow C in FIG. 6), and the folded portion 322 is accommodated in the surrounding portion 63 of the buffer member 60, whereby the folded portion 322 is It is pressed by the vertical wall 622 of the buffer member 60.
Thereby, the folding | returning part 322 is return | folded as the folding | turning axis lines 641 and 642 (refer FIG. 9) along the width direction of the upper housing | casing 20, and becomes a part linear form. Note that the vertical wall 622 of the buffer member 60 does not always need to press the folded portion 322 of the FPC 32.

Further, the surrounding portion 63 of the buffer member 60 accommodates the guide portion 333 of the grommet 33, and the top plate 621 forming the surrounding portion 63 is disposed at the height position of the flange portion 332 of the grommet 33. As a result, when the grommet 33 drops from the FPC insertion hole 223, the flange portion 332 of the grommet 33 contacts the top plate 621, thereby preventing the grommet 33 from falling off.
The surrounding portion 63 also accommodates a support plate 323 attached through the grommet 33, and the tip of the support plate 323 extends to the vicinity of the inner surface of the vertical wall 622 of the buffer member 60. Thus, when the grommet 33 drops from the FPC insertion hole 223, the tip of the support plate 323 contacts the buffer member 60, so that the grommet 33 is prevented from dropping indirectly via the support plate 323.
The buffer member 60 is provided with a rib 635 that protrudes toward the grommet 33. Thereby, in addition to the top plate 621, the grommet 33 can be more reliably prevented from falling off.

Next, the arrangement of the FPC 32 and the attachment of the buffer member 60 will be described.
The FPC 32 having one end connected to the glass substrate 261 of the touch panel 26 is inserted into the through hole 334 of the grommet 33 with the other end at the top. At this time, the grommet 33 is inserted from the guide portion 333 side, and the support plate 323 is also inserted together. Next, the other end side of the FPC 32 is inserted into the insertion hole 223 of the side portion 22 of the upper housing 20 together with the support plate 323 (see arrow D in FIG. 4), and the water stop portion 331 of the grommet 33 is press-fitted into the insertion hole 223. To do. Thereafter, the buffer member 60 is pushed into the mounting recess 35 of the upper housing 20 and attached from the hinge part 50 side while pushing the bent back part 322 of the FPC 32.
At this time, since the recess 630, the rib 631, the claws 632, 633, and the claw fitting portion 634 are provided along the mounting direction of the buffer member 60 with respect to the upper housing 20, the recess 630, the rib 631, the claws 632, 633 are provided. And the claw fitting part 634 positions the buffer member 60 with respect to the upper housing 20.

  As shown in FIGS. 11 and 12, one end 111 is connected to the first circuit board 31 of the upper housing 20 at the center in the width direction of the upper housing 20 on the outer side surface 282 of the insert metal plate 28, and the other end 112 is connected to the other end 112. A connection cable 11 connected to the second circuit board 43 of the lower housing 40 is arranged. The connection cable 11 is formed by bundling a plurality of thin electric wires in a circular cross section and has flexibility, and a second rotation shaft that rotatably connects the upper housing 20 and the lower housing 40. 52 is routed between the upper casing 20 and the lower casing 40 through the inside of the casing 52.

  Since the connection cable 11 is drawn into the upper housing 20 through the inside of the second rotation shaft 52, the connection cable 11 is introduced into the upper housing 20 from the central portion in the thickness direction of the upper housing 20. Accordingly, a cable insertion hole (insertion hole) 36 through which the connection cable 11 is passed is formed at a position corresponding to the second rotation shaft 52 in the lower side portion 222.

On the other hand, since the insert metal plate 28 is attached to the center of the upper housing 20 in the thickness direction, the connection cable 11 introduced into the upper housing 20 from the cable insertion hole 36 interferes with the insert metal plate 28. The first circuit board 31 that connects the one end 111 of the connection cable 11 is attached to the outer side surface 282 of the insert metal plate 28.
For this reason, a notch 283 is provided at a position corresponding to the cable insertion hole 36 at the hinge side end of the insert metal plate 28, and the connection cable 11 is introduced into the upper housing 20.

Thereby, the thickness of the housing can be suppressed while the housing is reinforced with the insert metal plate. However, in this case, the stress applied to the insert sheet metal is concentrated in the vicinity of the notch 283 having a low strength, and the vicinity of the notch 283 is easily damaged. Therefore, as will be described later, the force applied to the vicinity of the notch 283 is dispersed by the fixing member 70.
Further, the connection cable 11 is bent to the outer surface side by the notch 283 and connected to the first circuit board 31 provided on the outer surface side surface 282 of the insert sheet metal 28.

  As shown in FIG. 4, the connection cable 11 introduced into the upper housing 20 through the cable insertion hole 36 and bent and wired from the notch 283 of the insert sheet metal 28 to the outer surface side of the insert sheet metal 28 is fixed to the fixing member 70. Is attached to a predetermined position of the insert metal plate 28.

  As shown in FIGS. 12 to 14, the fixing member 70 has a linear tunnel portion 71 in which the connection cable 11 is accommodated, and an abutting contact with the outer side surface 282 of the insert metal plate 28 provided on both sides of the tunnel portion 71. A contact portion 72 and a fixing portion 73 provided outside the contact portion 72 and fixing the fixing member 70 to the insert metal plate 28 are provided. A plurality of cable retainers 711 that are protrusions for fixing the connection cable 11 to the tunnel portion 71 are provided on the inner surface of the tunnel portion 71 facing each other. Further, the fixing portion 73 is provided with a screw hole 731 for a screw 732 (see FIG. 4) that is fixed to the insert metal plate 28.

  A pair of left and right flat-plate-shaped covering portions 74 that cover the notches 283 of the insert metal plate 28 and a pair of left and right engaging protrusions that engage with the inner surface of the cable insertion hole 36 are formed at the end of the fixing member 70 on the hinge portion 50 side. 75. When the engagement protrusion 75 is inserted into the cable insertion hole 36, the top part abuts on the upper surface of the cable insertion hole 36, and the movement of the fixing member 70 upward (outer surface side) is restricted. Prevents jumping up.

  Therefore, when arranging the connection cable 11, the one end 111 (see FIG. 4) of the connection cable 11 is passed through the second rotation shaft 52 and from the cable insertion hole 36 of the upper case 20 to the inside of the upper case 20. And is bent from the notch 283 of the insert metal plate 28 to the outer side surface 282 of the insert metal plate 28 and arranged. Alternatively, the other end 112 of the connection cable 11 can be routed from the notch 283 of the insert metal plate 28 to the cable insertion hole 36 and routed to the lower housing 40 side through the second rotation shaft 52.

  Then, after arranging the connection cable 11, the tip of the connection cable 11 is connected to the first circuit board 31, and the fixing member 70 is covered so that the connection cable 11 is accommodated in the tunnel portion 71 of the fixing member 70. At this time, the front end of the engagement protrusion 75 is inserted into the cable insertion hole 36 and engaged, and the notch 283 of the insert metal plate 28 is covered by the covering portion 74 and fixed to the insert metal plate 28 by the screw 732.

  As shown in FIG. 15, the fixing member 70 </ b> B may be configured by combining semi-fixing members 701 and 702 that are divided along the generatrix at the top portion 712 of the tunnel portion 71. In this case, since the left and right semi-fixing members 701 and 702 are integrated by being fixed to the insert metal plate 28 with screws 732, they can be used separately.

As described above, according to the mobile terminal 10 of the embodiment according to the present invention described above, the upper housing 20 having the frame-shaped side portion 22 is connected to the lower housing 40 via the hinge portion 50 so as to be opened and closed. An insert sheet metal 28 is disposed at the center in the thickness direction inside the upper housing 20. A first circuit board 31 is laminated on the insert metal plate 28, and a second circuit board 43 is provided inside the lower housing 40.
The first circuit board 31 and the second circuit board 43 are electrically connected by a connection cable 11 having flexibility. The connection cable 11 passes through the cable insertion hole 36 provided in the central portion in the thickness direction of the hinge-side side portion 22 of the upper housing 20 and enters the upper housing 20, and is provided on the insert sheet metal 28. The first circuit board 31 on the outer side surface 282 is reached after passing through the notch 283.

  The relative position of the connection cable 11 with respect to the insert sheet metal 28 is fixed by the fixing member 70 having the engaging protrusion 75 that engages with the inner surface of the cable insertion hole 36, so that the upper housing 20 and the lower housing are centered on the hinge portion 50. Even if the body 40 is opened / closed or rotated relatively, the fixing member 70 does not move. For this reason, it is possible to prevent the connection cable 11 from moving inside the upper housing 20, and to prevent disconnection of the connection cable 11 and damage to the first circuit board 31. The fixing member 70 has one end engaged with the inner surface of the insertion hole 36 and the other end fixed to the insert metal plate 28. Therefore, the force applied to the insert metal plate 28 is not concentrated in the vicinity of the notch 283 but is also distributed to the insertion hole 36. Therefore, the strength near the notch 283 can be increased.

  By attaching the fixing member 70, the thickness necessary for accommodating the vicinity of the fixing member 70 is increased accordingly. However, in this Embodiment, it is comprised so that the location which needs to provide the insertion hole 36 among the side walls of a housing | casing may become thick. For this reason, even if the thickness of the portion away from the insertion hole 36 is increased, the influence on the thickness of the entire housing is smaller than the increase in the thickness near the insertion hole 36. In the present embodiment, one end of the fixing member 70 extends to the insertion hole 36 and engages with the inner surface of the insertion hole 36. Therefore, the fixing member 70 does not affect the thickness near the insertion hole 36.

  In the present embodiment, since the first circuit board 31 is disposed at a position away from the insertion hole 36, there is a sufficient space in the thickness direction between the insertion hole 36 and the first circuit board 31. Therefore, the thickness of the entire housing can be suppressed by arranging the fixing member 70 in this space.

In addition, since the fixing member 70 has the tunnel portion 71 that covers the connection cable 11, a good shielding property (noise countermeasure) can be obtained by completely covering the connection cable 11 with the tunnel portion 71.
If the purpose is to reinforce the vicinity of the notch 283, it is sufficient that the fixing member 70 has a length that can be fixed to the insert metal plate 28 (for example, up to the vicinity of the screw hole 732). However, in this embodiment, in order to ensure the shielding property of the connection cable 11, the tunnel portion 71 of the fixing member 70 is extended to the vicinity of the first circuit board. Even if the length of the tunnel portion 71 is shorter, some shielding properties can be obtained.

  Furthermore, since the cable presser 711 protruding from the inner surface of the tunnel portion 71 is provided, the connection cable 11 can be reliably fixed inside the tunnel portion 71.

The upper housing 20 includes a rectangular frame side part 22, a bottom part 23 provided on the flat part 228 on one end side of the side part 22, and a touch panel 26 provided on the flat part 221 on the other end side of the side part 22. The first circuit board 31 accommodated in the internal space 24 and the glass substrate 261 of the touch panel 26 outside the internal space 24 are connected by the FPC 32.
The end surface 261A of the glass substrate 261 is located outside the upper housing 20, and the FPC 32 drawn out from the end surface 261A of the glass substrate 261 passes outside the upper housing 20 and communicates with the inside and outside of the upper housing 20. The first circuit board 31 in the upper housing 20 is connected through the FPC insertion hole 223. At this time, since the grommet 33 provided in the FPC 32 is press-fitted and fitted into the FPC insertion hole 223, reliable waterproofness can be obtained even if the FPC 32 is routed from the outside of the upper housing 20 to the inside.

  In addition, since the hinge portion 50 side of the upper housing 20 has a dead space such as a relief portion for a screw for attaching the hinge portion 50 to the upper housing 20, the rectangular first circuit board 31 interferes with the relief portion. It is arranged at the position not to. Although the escape portion itself is a small space, since the rectangular first circuit board 31 is disposed at the retracted position, a dead space is generated as a result. Since the folded portion 322 of the FPC 32 is disposed at this location, a new space is not required, and the enlargement and thickness of the upper housing 20 can be avoided.

  Further, since the receiver cover 341 that covers the other end of the side portion 22 is provided on the opposite side of the glass substrate 261 from the side from which the FPC 32 is drawn, there is no need to provide a hole for the receiver 34 in the glass substrate 261.

Further, the upper housing 20 and the lower housing 40 are connected to the upper housing 20 and orthogonal to the first coaxial 51 and are arranged along the width direction of the upper housing 20. The hinge portion 50 having the second coaxial 52 is connected to be openable and closable and rotatable. Further, the connection line 32 having both ends connected to the inside of the upper housing 20 has the folded portion 322 arranged outside the upper housing 20.
A buffer member 60 is provided at the corner of the upper housing 20 on the hinge portion 50 side, and the buffer member 60 can contact at least a part of the folded portion 322 of the FPC 32, so that the FPC 32 extends. It is possible to limit the deformation to be attempted and to arrange a predetermined position.
Therefore, when the upper housing 20 is rotated with respect to the lower housing 40 about the second rotation shaft 52, the corner portion of the upper housing 20 damages the lower housing 40 by the same buffer member 60. Since the deformation of the FPC 32 is restricted, the number of parts can be reduced.

  The FPC 32 has a belt-like shape, and both end portions thereof are fixed to the upper housing 20, but are temporarily routed outside the side portion 22 of the upper housing 20 in the middle. In the FPC 32, a folded portion 322 is formed on the outside of the upper housing 20 with the lines along the width direction of the upper housing 20 as folding shafts 641 and 642, and the surrounding portion 63 of the buffer member 60 is Since the folded portion 322 is surrounded from the radial direction, it is possible to prevent the arrangement position of the FPC 32 from being shifted.

  In addition, since the buffer member 60 is attached to the upper housing 20 from the hinge portion 50 side, the buffer member 60 pushes the FPC 32 in parallel with the direction of the axis of the FPC 32 during installation, thereby shifting the routing position. The buffer member 60 can be attached without any problem.

  The buffer member 60 is provided with ribs 623 and 624 that protrude toward the upper housing 20, and the ribs 623 and 624 are formed from the center in the thickness direction of the upper housing 20 on the second rotation shaft 52 side. Since it is provided along the mounting direction of the buffer member 60, the buffer member 60 can be positioned and mounted without shifting the routing position of the FPC 32.

  Since the hinge portion 50 has convex portions 53 and 54 that extend from the widthwise end of the upper housing 20 toward the upper housing 20, and the upper housing 20 has concave portions 226 and 227 corresponding to the convex portions 53 and 54, It is possible to prevent the upper housing 20 from rattling against the hinge portion 50.

In the above-described embodiment, the waterproof structure and the configuration in which the housings are connected with the connection cable have been described. However, the present invention is not limited to this. The technical idea shown in the present embodiment can be widely applied to the configuration in which the insert sheet metal is provided in the housing.
The reason why the insertion hole 36 is configured as a hole formed in the side wall of the housing 20 is to close the insertion hole 36 when waterproofing. Therefore, when waterproofing is not considered, the side wall of the housing 20 may be made lower and the insertion hole 36 may be configured as a simple notch. In this case, the fixing member 70 is configured to engage with a cover that is fitted to the upper housing 20 instead of engaging with the inner wall of the insertion hole 36.
Note that the electronic apparatus of the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
