And a hinge 30 that rotatably connects the upper housing 10 and the lower housing 20. The electronic components mounted on the upper housing 10 include a display and the like. The electronic components mounted on the lower housing 20 include a keypad having a plurality of operation keys and an electronic board having a signal processing circuit and a control circuit.

  The upper housing 10 and the lower housing 20 are connected via a cable 50, and supply of power supply voltage and input / output of electric signals are performed between them. As the cable 50, for example, flexible wiring (FPC: Flexible printed circuits) or coaxial thin wire can be employed. The cable 50 is disposed between the upper housing 10 and the lower housing 20 through the hinge 30.

  The upper housing 10 has an internal accommodation space 11 as a waterproof region. Although not particularly limited, the upper casing 10 has the rear panel 18 bonded to the rear opening, and the rear opening is water-stopped.

<Configuration of cable lead-out part of upper housing>
FIG. 2 is a perspective view showing a waterproof member fitted to the upper housing. FIG. 3 is a plan view showing a state in which a waterproof member is fitted to the upper housing.

  Around the cable lead-out portion of the upper housing 10, there are a through hole 12 (see FIG. 3) of the upper housing 10, a waterproof member 52, an anti-detachment component 40, and a hinge cover (corresponding to an outer cover) 31. Is provided.

  The through hole 12 (see FIG. 3) is a hole through which the cable 50 passes through the accommodation space 11 of the upper housing 10. The through-hole 12 is provided at a location facing the hinge 30 of the upper housing 10.

  The waterproof member 52 is a member that covers the cable 50 and fits into the through hole 12. The waterproof member 52 has elasticity, and prevents water from entering the through hole 12 when fitted to the through hole 12. The waterproof member 52 includes a press-fit portion 52a on one end side and a stopper portion 52b on the other end side.

  As shown in FIG. 3, in the waterproof member 52, the press-fit portion 52 a is press-fit from the hinge 30 side to the accommodation space 11 side, and the stopper portion 52 b is locked and fixed in front of the through hole 12. The press-fit portion 52 a is fixed before passing through the through hole 12. Therefore, when the waterproof member 52 is fixed, the waterproof member 52 may come out of the through hole 12 by applying a force to pull the cable 50 or vibration.

  The hinge cover 31 is a component that covers the portion where the cable lead-out portion of the upper housing 10 is located and becomes an exterior of the apparatus. In the assembly process of the portable terminal device, the cable 50 and the waterproof member 52 are assembled with the hinge cover 31 removed.

  FIG. 4 is a perspective view of the removal preventing part. FIG. 5 is a perspective view showing a state in which the removal prevention component is fixed to the upper housing.

  The removal preventing part 40 is a member that serves as a stopper of the waterproof member 52 and prevents the waterproof member 52 from coming out of the through hole 12. The removal prevention component 40 is fixed to the upper housing 10 inside the hinge cover 31 so as to face the rear end of the waterproof member 52. As shown in FIG. 5, the drop prevention component 40 is fixed in a state where the waterproof member 52 can be visually recognized from above without covering the entire waterproof member 52.

  The disconnection prevention component 40 includes a fixing portion 41, a gate portion 42, a stopper portion 43, and two top surfaces 44 and 45 having different heights.

  The fixing portion 41 is fitted in the concave groove 13 (see FIG. 3) of the upper housing 10 to fix the removal preventing component 40. The stopper portion 43 is disposed opposite to the rear end of the waterproof member 52 to prevent the waterproof member 52 from coming off. The cable 50 is led out to the hinge 30 side through the gate portion 42.

  The top surface 44 is pressed by the hinge cover 31 and serves to eliminate backlash of the removal preventing part 40.

  The other top surface 45 is disposed adjacent to the alignment surface 14 of the upper housing 10 and at substantially the same height (specifically, slightly lower) as the alignment surface 14 in a normal fixed state. . The top surface 45 makes it possible to identify when the waterproofing member 52 is in an abnormally fixed state such as a state where the removal preventing part 40 is forcibly pushed in at a stage where the waterproof member 52 has not been inserted to the end. In the assembly process of the apparatus, the operator can identify the normal fixed state or the abnormal fixed state by comparing the heights of the top surface 45 and the alignment surface 14.

  The top surface 45 for height comparison may be changed to a rib.

<Effect of cable lead-out part of upper housing>
With the configuration described above, in the mobile terminal device according to the present embodiment, the waterproof member 52 is normally and properly removed by the disconnection prevention component 40 before the hinge cover 31 is fixed to the hinge 30 and the cable 50 and the waterproof member 52 are covered. It is fixed so that it does not come off.

  Therefore, it can be avoided that the waterproof member 52 is fixed in an abnormal state in the device assembly process, and the waterproof property of the upper housing 10 is deteriorated.

  Further, when the stopper of the waterproof member 52 is configured by providing a relatively long rib on the inside of the hinge cover 31 by integral molding of resin, defects such as sink marks may occur on the outer surface of the hinge cover 31. However, in the mobile terminal device of the present embodiment, there is no possibility that such a defect will occur on the outer surface of the hinge cover 31.

<Configuration of lower cable section>
FIG. 6 is an exploded perspective view showing the lower casing of the mobile terminal device according to the embodiment of the present invention.

  Around the cable lead-out portion of the lower housing 20, a through hole 22, a waterproof member 53, an antenna substrate 60, an antenna plate (corresponding to a disconnection prevention component) 70, and an outer cover 80 are provided. Yes. In the following description, the lower housing 20 corresponds to the first housing, and the upper housing 10 corresponds to the second housing.

  The through hole 22 is a hole through which the cable 50 passes through the accommodation space 21 (see FIG. 11) of the lower housing 20. The accommodation space 21 is a waterproof area. The through hole 22 is provided in the vicinity of the hinge 30 of the lower housing 20.

  The waterproof member 53 is a member that covers a part of the cable 50 and fits into the through hole 22. The waterproof member 53 has elasticity, and prevents water from entering the through hole 22 when fitted into the through hole 22. The shape of the waterproof member 53 and the manner of fitting into the through hole 22 are substantially the same as the waterproof member 52 of the upper housing 10.

  The antenna substrate 60 is a substrate (for example, FPC) on which a conductor serving as an antenna is formed. For example, the antenna substrate 60 is electrically connected to a circuit board inside the lower housing 20 via a contact exposed on the outer surface of the lower housing 20. Connected.

  The antenna substrate 60 is bonded and fixed to the back surface of the antenna plate 70, for example.

  7 is a plan view showing the front side of the antenna plate, FIG. 8 is a plan view showing the back side of the antenna plate, and FIG. 9 is a perspective view of the antenna plate viewed from the back side.

  The antenna plate 70 is a member that covers the antenna substrate 60 and fixes the antenna substrate 60 at a predetermined position. The antenna plate 70 prevents the antenna substrate 60 from touching the user's hand and deteriorating the antenna performance. The antenna plate 70 is not particularly limited, but is fixed to the lower housing 20 with screws.

  The antenna plate 70 has a stopper portion 71, and the stopper portion 71 faces the rear end of the waterproof member 53 fitted in the through hole 22 to prevent the waterproof member 53 from coming off. The stopper portion 71 is formed with a first rib (corresponding to a first protrusion) 72 and a second rib (corresponding to a first protrusion) 73 having different heights.

  FIG. 10 is a perspective view showing a state where the antenna plate is fixed to the lower housing. FIG. 11 is a longitudinal sectional view showing a portion of the lower housing where the waterproof member is fitted.

  The first rib 72 is formed in a range that covers the cable 50 in the stopper portion 71. The first rib 72 is a rib that protrudes inward of the lower housing 20. The first rib 72 abuts against the cable 50 even when the cable 50 is bent toward the antenna substrate 60 due to product variations or the like, and the cable 50 is very close to the antenna substrate 60. To prevent it.

  The second rib 73 is formed in a range avoiding the cable 50 in the stopper portion 71. The second rib 73 projects to the inside of the lower housing 20 with a larger projecting amount than the first rib 72. The second rib 73 is in contact with the outer peripheral portion 25 of the lower housing 20 and serves to float the antenna substrate 60 from the outer peripheral portion 25 of the lower housing 20 by a certain amount. Further, the second rib 73 serves to float the first rib 72 from the outer surface of the lower housing 20 by a predetermined amount so that the first rib 72 does not contact the cable 50 more than necessary.

  Further, as shown in FIGS. 10 and 11, the antenna plate 70 is fixed in a state where a part of the waterproof member 53 is exposed without covering the entire waterproof member 53. That is, in a state where the antenna plate 70 is fixed, the stopper portion 53 b of the waterproof member 53 is exposed in a gap between the stopper portion 71 of the antenna plate 70 and the outer peripheral surface of the lower housing 20.

  Furthermore, as shown in FIGS. 10 and 11, in a normal fixed state, the stopper portion 71 of the antenna plate 70, the stopper portion 53b of the waterproof member 53, and the outer surface 24 of the lower housing 20 adjacent thereto are Arranged at almost the same height. Therefore, by comparing these heights, the operator of the assembly process can identify whether or not the waterproof member 53 is in an abnormally fixed state. That is, when the waterproof member 53 is not normally pushed into the through hole 22, the antenna plate 70 is lifted when the antenna plate 70 is in an abnormally fixed state, such as being fixed so as to crush the waterproof member 53. ing.

<Effect of cable lead-out part of lower housing>
With the above configuration, in the mobile terminal device according to the present embodiment, before the cable 50 and the waterproof member 53 are covered with the outer cover 80, the waterproof member 53 is prevented from being normally removed by the stopper portion 71 of the antenna plate 70. Can be fixed to.

  Therefore, the inconvenience that the waterproof member 53 is fixed in an abnormal state in the assembly process of the apparatus and the waterproof property of the lower housing 20 is lowered can be avoided.

  Further, when the stopper of the waterproof member 53 is configured by providing a relatively long rib on the inner side of the outer cover 80 by integral molding of resin, defects such as sink marks may occur on the outer surface of the outer cover 80. However, in the mobile terminal device of the present embodiment, there is no possibility that such a defect will occur on the outer surface of the outer cover 80.

  The embodiments of the present invention have been described above.

  In the above-described embodiment, a configuration in which a flexible cable or a coaxial thin wire is used as the cable has been described as an example. However, various types of cables such as a normal conductive wire may be used.

  The present invention is applicable to portable terminal devices such as a mobile phone, a portable information terminal, and a portable music player.
