Description

  The present invention relates to a portable electronic device including a functional member such as a detachable battery that transmits and receives electric power.

  Paper diapers and sanitary products that use water-absorbing performance such as high water-absorbing polymers and high water-absorbing polymer gels are widespread, and water-absorbing and expanding members that are formed into sheets so that they can be used in other applications are also widely known. ing. And the prior art which utilized the water absorption expansion | swelling member for the waterproof use of the electronic device is disclosed by patent document 1 as a battery pack.

  The battery pack described in Patent Document 1 includes a buffer body having a window hole corresponding to the terminal window of the input / output terminal and abutting on the outer periphery of the terminal window. And this buffer body contains the water absorption expansion | swelling material which absorbs water and expand | swells. According to this configuration, the water-absorbing expansion material that has absorbed water expands, and the buffer closely adheres to the inner wall of the battery pack storage unit that stores the battery pack. As a result, since the intrusion of water from the periphery of the buffer body to the inner window hole is suppressed, the intrusion of water from the terminal window into the battery pack is also suppressed.

JP 2009-48914 A (pages 5-7, FIG. 6)

  However, the conventional battery pack maintains the electrical connection between the battery pack and the electronic device that stores the battery pack even when water enters the buffer body including the water absorbing and expanding material. As a result, if water that exceeds the water absorption capacity of the water-absorbing expansion material enters the location of the buffer body, the input / output terminals may get wet, causing malfunctions in the electronic equipment, wear-out of electronic components due to electrical leakage, and electric shock to the user. There is a possibility.

  The present invention has been made in view of the above points, and provides a portable electronic device that can prevent malfunction, leakage, and electric shock when wet, and is improved in safety. The purpose is to do.

  In order to solve the above-described problems, the present invention provides a portable electronic device having a functional member having a member terminal for transmitting and receiving electric power, the functional member being detachably accommodated and the member being accommodated when the functional member is accommodated. The member terminal is separated from the storage portion terminal when water is absorbed by being provided at a location between the storage portion where the storage portion terminal electrically connected to the terminal is disposed and the functional member in the storage portion. And a water absorbing expansion member that expands in the direction in which the functional member is moved and releases the electrical connection between the member terminal and the storage portion terminal.

  According to this configuration, the water-absorbing expansion member is provided at a location between the storage portion and the functional member in the storage portion of the functional member, and the functional member is moved so that the member terminal is separated from the storage portion terminal when water is absorbed. Inflates in the direction. And a water absorption expansion member cancels | releases the electrical connection of the member terminal of a functional member, and the accommodating part terminal of the accommodating part.

  The “functional member” means a member that operates by supplying electric power from a terminal (member terminal) or receiving electric power. This “functional member” can be a member such as “battery” or “ion generator” as in the means and embodiment described later, and is not limited to these members. The “functional member” may be, for example, a card-type memory device.

  Moreover, the portable electronic device having the above-described configuration is characterized in that the storage portion includes a gap that can store the functional member that moves due to expansion of the water-absorbing expansion member.

  According to this configuration, even if the functional member is moved by the water absorption and expansion of the water absorbing / expanding member, it does not protrude from the storage unit or the exterior of the portable electronic device does not come off. Thereby, a water absorption expansion member cancels | releases the electrical connection of the member terminal of a functional member, and the accommodating part terminal of the accommodating part, without changing the external appearance of a portable electronic device.

  In the portable electronic device having the above structure, the functional member is a battery for supplying power.

  According to this configuration, the water absorbing expansion member releases the electrical connection between the battery member terminal and the storage portion terminal of the storage portion. Thereby, when the portable electronic device gets wet, the power supply from the battery is cut off.

  In the portable electronic device having the above-described configuration, the functional member is an ion generator that emits ions.

  According to this configuration, the water-absorbing expansion member releases the electrical connection between the member terminal of the ion generator and the storage portion terminal of the storage portion. As a result, when the portable electronic device gets wet, the power supply to the ion generator is cut off.

  According to the configuration of the present invention, when the water-absorbing expansion member gets wet, the electrical connection between the member terminal of the functional member such as the battery or the ion generator and the storage unit terminal of the storage unit is released to cut off power transmission / reception. Therefore, it is possible to prevent the occurrence of malfunction, electric leakage, and electric shock due to getting wet with water, and it is possible to provide a portable electronic device with improved safety.
