Description

  The present invention relates to a mobile terminal device.

  As mobile terminal devices such as smartphones and tablet computers are being reduced in size, the space in which cables can be routed within the housing has become narrower.

JP 2007-80929 A

  In order to improve the performance of mobile terminal devices, the adoption of batteries having a high current supply capacity is being promoted. In this case, a cable having a large diameter is used as a cable for supplying current from the battery to the component. Since a cable with a large diameter has high rigidity, it is desirable to firmly fix a member that suppresses the movement of the cable to the housing in order to store the cable in a predetermined position. However, since the space in the housing is narrow, it is not preferable from the viewpoint of space saving that the number of parts is increased by the member that suppresses the movement of the cable.

  An object of one aspect is to save space.

  According to one embodiment, a housing, a cable provided on a substrate disposed in the housing, connected to a battery, a vibration source provided on the substrate, and provided on the substrate, And a fixture that fixes the vibration source to the substrate and covers at least a part of the cable.

  As one aspect, space saving can be achieved.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view of the mobile terminal device 100 according to the embodiment. The mobile terminal device 100 according to the embodiment is an information terminal device that is used while being carried by a user, such as a smartphone or a tablet personal computer. As illustrated in FIG. 1, the mobile terminal device 100 according to the embodiment includes a housing 10 in which a front case 12 and a rear case 14 are combined. The front case 12 and the rear case 14 are made of, for example, a resin material. The front case 12 has a touch panel assembled on the front surface.

  FIG. 2 is an exploded perspective view of the front case 12 with the rear case 14 removed. As shown in FIG. 2, a battery 20 and a component 22 such as a printed circuit board and / or an antenna for NFC (Near Field Communication) are mounted in the front case 12. The battery 20 is a battery having a high current supply capability. For this reason, the battery 20 is upsized and occupies more than half the area of the front case 12.

  3 is an enlarged perspective view of a part of FIG. As shown in FIG. 3, the battery 20 is mounted on the front case 12 while being fixed to the battery cover 18 with claws or the like. A cable 24 is connected to the battery 20. The cable 24 has a connector 26 on one end side, and is connected to the battery 20 by the connector 26 being inserted into the battery 20. Since a battery having a high current supply capability is used for the battery 20, a cable having a large diameter is used as the cable 24 in order to flow a large current. Therefore, the cable 24 has a property that it has high rigidity and is difficult to bend.

  FIG. 4 is a perspective view for explaining the cable 24. As shown in FIG. 4, the printed circuit board 30 is disposed in the front case 12. The printed circuit board 30 is equipped with a connector 32 and electronic components such as a CPU (Central Processing Unit). The cable 24 has a connector 28 on the other end side, and the connector 28 is inserted into a connector 32 provided on the printed circuit board 30. As a result, each electronic component mounted on the printed circuit board 30 is supplied with power from the battery 20 via the cable 24.

  Both the connector 26 at one end and the connector 28 at the other end of the cable 24 are inserted into the battery 20 and the connector 32 from a direction parallel to the upper surface of the printed circuit board 30. The connector 28 on the other end side of the cable 24 is inserted into the connector 32 from the same direction as the direction in which the connector 26 on the one end side is inserted into the battery 20. For this reason, the cable 24 is bent in a U shape so that the connector 26 on one end side is positioned above the printed circuit board 30 than the connector 28 on the other end side. The reason why the cable 24 is bent in a U-shape is to secure the extra length of the cable 24 and make it easy to insert and remove the connector 26 on one end side of the cable 24 from the battery 20.

  Since the cable 24 is highly rigid and difficult to bend, when the cable 24 is bent, a large force is generated in the cable 24 to return to the original state (for example, a state in which the cable 24 extends straight). For this reason, the cable 24 tends to move above the printed circuit board 30. If the cable 24 moves above the printed circuit board 30, when the rear case 14 is assembled to the front case 12, the cable 24 may interfere and the assembly may not be successful. For this reason, it is desirable to suppress the movement of the cable 24 above the printed circuit board 30.

  FIG. 5 is a perspective view of the battery 20 with the battery 20 removed in FIG. As shown in FIG. 5, a cover 40 is provided on the printed circuit board 30 to cover the cable 24. The cover 40 is made of, for example, a synthetic resin such as ABS resin or polycarbonate. The cover 40 covers, for example, the vicinity of the bent portion of the cable 24, and does not cover the vicinity of the one end side and the vicinity of the other end side of the cable 24. The cover 40 only needs to cover at least a part of the cable 24 and may cover the entire cable 24. The cover 40 is firmly fixed to the printed circuit board 30 by screws 42, screws 44, and screws 46 (not shown in FIG. 5). For this reason, even when the rigidity of the cable 24 is high, the movement of the cable 24 above the printed circuit board 30 can be suppressed.

  6 is a cross-sectional view taken along a line AA in FIG. As shown in FIG. 6, a display device 62 including a touch panel 60 is attached to the front surface of the front case 12. The touch panel 60 includes, for example, an LCD (Liquid Crystal Display), and displays images, various types of information, and operation input images such as touch operation buttons. On the printed circuit board 30 disposed in the front case 12, a cable 24, a battery 20, and the like are provided. A connector 26 at one end of the cable 24 is inserted into the battery 20, and a connector 28 at the other end is inserted into a connector 32 provided on the printed circuit board 30.

  A space 66 is formed on the opposite side of the cable 24 from the bent portion 64 of the cable 24 that is bent in a U-shape. By forming the space 66, when the battery 20 is inserted and removed from the battery cover 18 with the connector 26 on one end side of the cable 24 being inserted into the battery 20, it is possible to secure an area for movement and deflection of the cable 24. .

  A space 68 may be formed between the cable 24 and the portion of the cover 40 that covers the cable 24, or the cable 24 may be in contact with the cover 40 without forming the space 68. Good. The space 68 is preferably formed from the viewpoint of securing the movement and bending area of the cable 24.

  A rear case 14 is fitted to the outside of the front case 12. A seal member 16 made of an elastic member is provided around the rear case 14. Since the seal member 16 abuts on the front case 12, the waterproof property of the space formed between the front case 12 and the rear case 14 is secured. Note that the rear case 14 may be fitted inside the front case 12.

  FIG. 7 is an exploded perspective view in which components mounted on the printed circuit board 30 are disassembled. 8 is a cross-sectional view taken along the line AA in FIG. FIG. 9 is a view of the state in which the parts disassembled in FIG. 7 are combined as seen from the Z direction. As shown in FIGS. 7 to 9, a vibration source 34 such as a vibrator is mounted on the printed circuit board 30 in addition to the cable 24 and the like. By mounting the vibration source 34, the housing 10 can be shaken by the vibration source 34 when a predetermined condition is satisfied, and the user can be notified. The vibration source 34 is firmly fixed by a cover 40 fixed to the printed circuit board 30 with a screw 42, a screw 44, and a screw 46. For this reason, the vibration of the vibration source 34 is efficiently transmitted to the housing 10.

  The cable 24 and the vibration source 34 are arranged side by side without any other components other than the cover 40 therebetween. For example, the cable 24 and the vibration source 34 are arranged side by side with their longitudinal directions facing substantially the same direction. Thereby, the mounting space in the direction in which the cable 24 and the vibration source 34 are arranged can be reduced.
