  The connector has a board connection terminal for being electrically connected to the wiring of the main board. Water that has entered the opening of the connector may enter the inside of the electronic device from the location where the board connection terminals are disposed. For this reason, the connector is often covered with a seal member so as to cover the board connection terminals. However, since the board connection terminals occupy a predetermined area, many sealing members are required to waterproof the board connection terminals of the connector.

  Embodiments of an electronic device according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a schematic perspective view showing a configuration example of an electronic apparatus according to an embodiment of the present invention. Note that in this embodiment, an example in which a mobile phone is used as an electronic apparatus according to the present invention will be described. The electronic device is not limited to a mobile phone as long as it is a device having a connector having an opening for connecting external wiring. For example, a PDA (Personal Digital Assistant), a personal computer, a television receiver, a portable game Or a portable music player or portable video player. Moreover, as a connector having an opening for connecting external wiring, for example, an earphone jack or the like can be used.

  As shown in FIG. 1, the main body housing of the mobile phone 10 is formed by assembling an upper case 11 and a lower case 12. On the surface of the upper case 11, a touch panel 13, a receiver 14, a microphone 15, and a touch key 16 are provided.

  The touch panel 13 includes a display unit and a touch sensor as an input unit provided in the vicinity of the display unit. The display unit is configured by a general display output device such as a liquid crystal display or an OLED (Organic Light Emitting Diode) display. The touch sensor gives the information on the position indicated by the user on the touch sensor to the CPU of the mobile phone 10. Various types of touch sensors such as a capacitive sensor, a pressure-sensitive sensor, and a resistive film sensor are known, and any of these can be used.

  The receiver 14 outputs sounds corresponding to various types of information including received voices. The microphone 15 converts voice input by the user into a digital voice signal. The touch key 16 is composed of, for example, a capacitive touch sensor, and outputs a signal corresponding to a user's touch operation on the key.

  On the other hand, a power button 17 is provided on one side surface of the lower case 12 for receiving a system start instruction or end instruction by the user. An opening is provided on one side surface of the lower case 12, and the connector 20 is inserted into this opening.

  FIG. 2 is an exploded perspective view showing an example of the structure of the mobile phone 10 with a part thereof omitted. FIG. 3 is a bottom view showing a configuration example of the connector 20. 4 is a side view showing a configuration example of the connector 20 viewed from the IV direction of FIG. 3, and FIG. 5 is a side view showing a configuration example of the connector 20 viewed from the V direction of FIG. is there.

  As shown in FIG. 2, the main board 40 is assembled to the upper case 11 in advance. The connector 20 is assembled to the lower case 12 in advance. By assembling the screw holes 51 provided in the upper case 11 and the connection pins 52 provided in the lower case 12 to be engaged with each other, the housing of the mobile phone 10 is formed.

  A plurality of connector connection terminals 41 for electrical connection with the connector 20 are arranged on the main surface of the main board 40 on which the wiring is formed. The main board 40 is a printed circuit board, and an electronic circuit such as a CPU is disposed on the main surface.

  The connector 20 includes an external connection housing 21, a waterproof ring 22, and a support housing 23.

  The external connection housing 21 has a cylindrical shape with both ends opened, and a plug for external wiring is inserted into and removed from a jack 24 serving as an opening at one end. On the other hand, the opening 25 at the other end of the external connection housing 21 is blocked by a seal member 26 (see FIG. 4). For this reason, the water that has entered from the opening 24 does not leak into the mobile phone 10 from the opening 25 at the other end of the external connection housing 21.

  The waterproof ring 22 is made of resin or the like, and is tightly pressure-bonded to the inner wall of the lower case 12. The waterproof ring 22 prevents water from entering the inside of the mobile phone 10 from the gap between the opening of the lower case 12 and the outer periphery of the external connection housing 21.

  The support housing 23 has a locking piece 27 on the side surface. The support housing 23 is fixed to the lower case 12 via a locking piece 27 by screws or screws.

  A board connection terminal 28 and a buckling prevention part 29 for electrically connecting the connector 20 to the main board 40 are provided on the bottom surface of the support housing 23 (see FIG. 3).

  The board connection terminal 28 is formed of a conductive planar member, and is provided in a plane so as to be substantially in contact with the support housing 23. As the conductive planar member, for example, a metal thin plate or thin film, a conductive paste, or the like can be used. The board connection terminal 28 is configured to be electrically connected to the plug when the plug is inserted into the jack 24.

  As shown in FIG. 5, the buckling prevention portion 29 is configured to have a predetermined height D from the surface of the board connection terminal 28. The buckling prevention portion 29 is a member that abuts on the main surface of the main substrate 40 and is not a member that requires electrical connection with the main substrate 40, and therefore is configured of an insulating member such as a resin. Is preferred.

  As shown in FIG. 2, the board connection terminals 28 on the outer peripheral surface of the support housing 23 and the connector connection terminals 41 on the main surface of the main board 40 are arranged at positions corresponding to each other. Further, when the upper case 11 and the lower case 12 are assembled with each other, the connector connecting terminal 41 is contacted by the board connecting terminal 28 so that the support housing 23 is placed on the connector connecting terminal 41. The connector 20 and the main board 40 are supported so that the board connection terminals 28 and the connector connection terminals 41 are electrically connected to each other while being pressed.

  When the upper case 11 and the lower case 12 are assembled, the board connecting terminals 28 press the corresponding connector connecting terminals 41 while being in contact with each other. As a result, the board connection terminal 28 is electrically connected to the connector connection terminal 41, and the plug inserted into the jack 24 and the main board 40 are electrically connected.

  FIG. 6 is an explanatory diagram showing a configuration example of the connector connection terminal 41 provided on the main board 40.

  The connector connecting terminal 41 is a plug spring made of a conductive elastically deformable member such as a spring plate made of metal. The connector connection terminal 41 is configured to have a height d0 from the main surface of the main board 40. When the connector connecting terminal 41 is pressed by the planar board connecting terminal 28, the connector connecting terminal 41 is biased to return to the original position while yielding a predetermined distance.

  The height d0 of the connector connecting terminal 41 can be easily changed. For this reason, the mounting height of the connector 20 can be changed by changing the height d0 of the connector connection terminal 41.

  By the way, the connector connecting terminal 41 is formed of a member that can be elastically deformed. If a stress exceeding the elastic limit is applied and the member yields larger than the predetermined displacement amount d1, the member is inelastically deformed and cannot return to the original position. For this reason, it is preferable that the connector connecting terminal 41 does not yield more than a predetermined displacement d1.

  Therefore, the mobile phone 10 according to the present embodiment includes a buckling prevention portion 29 having a predetermined height D from the surface of the substrate connection terminal 28 of the support substrate 23. When the upper case 11 and the lower case 12 are assembled, the buckling prevention portion 29 abuts against the main surface of the main substrate 40, so that the main surface of the main substrate 40 and the surface of the substrate connection terminal 28 are predetermined. The height D can be separated.

  Therefore, by determining the predetermined height D so that the distance obtained by subtracting the predetermined height D from the height d0 of the connector connecting terminal 41 is smaller than the predetermined displacement d1, the connector connecting terminal 41 is , It will not yield more than the predetermined displacement d1. Therefore, according to the buckling prevention part 29, it is possible to prevent the connector connecting terminal 41 from being subjected to stress exceeding the elastic limit.

  When the board connecting terminal 28 is formed of a member that can be elastically deformed, it is necessary to waterproof a joint portion of the member that can be elastically deformed with the support member 23. Moreover, the range which can deform | transform this member will be limited by waterproofing a junction part.

  On the other hand, the board connection terminal 28 of the connector 20 of the mobile phone 10 according to the present embodiment is configured by a planar conductive member provided in a plane so as to be substantially in contact with the support member 23. Therefore, since the board connection terminal 28 does not operate and the operation area does not need to be waterproofed, the waterproof area of the connector 20 can be greatly reduced as compared with the case where the board 20 is constituted by an elastically deformable member.

  Further, the connector 20 of the mobile phone 10 according to the present embodiment is not a board mounting type, and it is not necessary to attach the connector 20 to the main board 40 of the upper case 11. Therefore, after the connector 20 is first assembled to the lower case 12, the upper case 11 and the lower case 12 can be assembled to form the casing of the mobile phone 10. Therefore, the mobile phone 10 according to the present embodiment is easy to assemble.

  Further, since the connector 20 can be assembled to the lower case in advance, the mating surface of the upper case 11 and the lower case 12 can be easily made flat, and the outer edge of the mating surface can be easily formed. Can be straight. Therefore, according to the mobile phone 10 according to the present embodiment, the degree of freedom in design increases.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
