　図５は、図２中の矢印Ｖに示す方向から見た携帯型電話機を示す図である。図２および図５を参照して、パッキン３１は、プラグ挿入部２１の開口形状に対応した形状、本実施の形態では、円形の平面視を有する。パッキン３１は、プラグ挿入部２１の開口を塞ぐ第１位置にある時に、プラグ挿入部２１の開口の外周で外面１３と重なり合うように設けられている。パッキン３１は、プラグ挿入部２１の開口よりも大径を有して形成されている。 FIG. 5 is a diagram showing the mobile phone viewed from the direction indicated by the arrow V in FIG. 2 and 5, packing 31 has a shape corresponding to the opening shape of plug insertion portion 21, in this embodiment, a circular plan view. The packing 31 is provided so as to overlap the outer surface 13 on the outer periphery of the opening of the plug insertion portion 21 when the packing 31 is in the first position for closing the opening of the plug insertion portion 21. The packing 31 has a larger diameter than the opening of the plug insertion portion 21.
　このような構成によれば、パッキン３１とプラグ挿入部２１の開口との間に隙間が生じることを抑制し、パッキン３１による異物の侵入を防ぐ効果を高めることができる。 According to such a configuration, it is possible to suppress the occurrence of a gap between the packing 31 and the opening of the plug insertion portion 21, and to enhance the effect of preventing the foreign material from entering by the packing 31.
　プラグ７２がプラグ挿入部２１に挿入されていない通常時、電極部４２は、プラグ挿入部２１より退避した電極部収容部１８に収容されている。このとき、板ばね４１の第２辺部４４は、側面４７に面接触した状態で、第３辺部４３から第１辺部４５に近づくほど第２底壁部１７からの距離が大きくなるように傾斜している。 When the plug 72 is not inserted into the plug insertion part 21, the electrode part 42 is accommodated in the electrode part accommodation part 18 retracted from the plug insertion part 21. At this time, the distance from the second bottom wall portion 17 increases as the second side portion 44 of the leaf spring 41 comes into surface contact with the side surface 47 and approaches the first side portion 45 from the third side portion 43. It is inclined to.
　図３を参照して、携帯型電話機１０のバッテリ充電時、充電用コネクタ７０のプラグ７２がプラグ挿入部２１に挿入される。 Referring to FIG. 3, when battery of mobile phone 10 is charged, plug 72 of charging connector 70 is inserted into plug insertion portion 21.
　パッキン３１は、プラグ７２に押されることによって、プラグ挿入部２１の開口を塞ぐ第１位置から、プラグ挿入部２１の開口から見て電極部４２よりも奥まった第２位置に向けて移動する。パッキン３１は、柔軟性を有するため、プラグ挿入部２１の開口よりも大径を有するにもかかわらず、変形しながらプラグ挿入部２１内に進入する。第２位置において、パッキン３１は、プラグ挿入部２１に対するプラグ７２の挿入方向において、電極部挿入孔２４と第１底壁部２３との間に位置決めされる。 When the packing 31 is pushed by the plug 72, the packing 31 moves from the first position where the opening of the plug insertion portion 21 is blocked toward the second position deeper than the electrode portion 42 when viewed from the opening of the plug insertion portion 21. Since the packing 31 has flexibility, the packing 31 enters the plug insertion portion 21 while being deformed despite having a larger diameter than the opening of the plug insertion portion 21. In the second position, the packing 31 is positioned between the electrode portion insertion hole 24 and the first bottom wall portion 23 in the insertion direction of the plug 72 with respect to the plug insertion portion 21.
　本実施の形態では、ステム３３、プレート３５および板ばね４１が、パッキン３１と電極部４２との間を連結し、プラグ挿入部２１へのプラグ７２の挿入時、第１位置から第２位置に移動するパッキン３１の動きを、電極部４２を電極部収容部１８からプラグ挿入部２１に向けて移動させる動きに変換する移動機構部として設けられている。 In the present embodiment, the stem 33, the plate 35, and the leaf spring 41 connect the packing 31 and the electrode portion 42, and when the plug 72 is inserted into the plug insertion portion 21, the first position is changed to the second position. The moving packing 31 is provided as a moving mechanism that converts the movement of the packing 31 into movement that moves the electrode 42 from the electrode housing 18 toward the plug insertion portion 21.
　すなわち、パッキン３１が第１位置から第２位置に移動すると、その動きがステム３３を介してプレート３５に伝わる。プレート３５は、コイルばね３７を押し縮めながら基板電極３９に近接していく。このプレート３５の動きに伴って、プレート３５に接続された第１辺部４５が支持台４６の側面４８に近接していくことにより、第２辺部４４が頂辺４６ｐを支点に倒れ、側面４８に載置された状態となる。このとき、第３辺部４３が支持台４６の側面４７から離れる方向に移動することにより、電極部４２が電極部挿入孔２４を通じてプラグ挿入部２１に進入する。 That is, when the packing 31 moves from the first position to the second position, the movement is transmitted to the plate 35 via the stem 33. The plate 35 approaches the substrate electrode 39 while pushing and shrinking the coil spring 37. As the plate 35 moves, the first side 45 connected to the plate 35 approaches the side surface 48 of the support base 46, so that the second side 44 falls over the top side 46 p as a fulcrum, and the side surface 48 is placed. At this time, the third side portion 43 moves in a direction away from the side surface 47 of the support base 46, whereby the electrode portion 42 enters the plug insertion portion 21 through the electrode portion insertion hole 24.
　電極部４２は、電極部収容部１８からプラグ挿入部２１に進入することにより、プラグ７２と接触する。プラグ７２から供給される電力は、電極部４２、板ばね４１、プレート３５およびコイルばね３７を順に伝わって、基板電極３９に送られる。 The electrode part 42 comes into contact with the plug 72 by entering the plug insertion part 21 from the electrode part accommodating part 18. The electric power supplied from the plug 72 is transmitted to the substrate electrode 39 through the electrode portion 42, the leaf spring 41, the plate 35, and the coil spring 37 in order.
　コイルばね３７が押し縮められることにより、コイルばね３７からパッキン３１に対して、第２位置から第１位置に押し戻す力が作用される。バッテリ充電の終了後、プラグ挿入部２１からプラグ７２を引き抜く際に、コイルばね３７からパッキン３１に作用する力によって、パッキン３１を第２位置からプラグ挿入部２１の開口を塞ぐ元の第１位置に戻す。 When the coil spring 37 is compressed, a force to push back the coil spring 37 from the second position to the first position is applied to the packing 31. When the plug 72 is pulled out from the plug insertion portion 21 after the battery charging is finished, the first position where the packing 31 is closed from the second position to the opening of the plug insertion portion 21 by the force acting on the packing 31 from the coil spring 37. Return to.
　本実施の形態における携帯型電話機１０では、バッテリ充電時にコイルばね３７の弾性力に抗して、パッキン３１を第２位置に保持するためのロック機構が設けられている。 The mobile phone 10 according to the present embodiment is provided with a lock mechanism for holding the packing 31 in the second position against the elastic force of the coil spring 37 when the battery is charged.
　より具体的には、本体ケース１２は、プラグ挿入部２１に挿入されたプラグ７２が嵌め合わされる嵌合部１５を有する。嵌合部１５は、外面１３と第１側壁部２２との角部に設けられている。一方、図３中に示すように、プラグ７２は、小径部７３と、小径部７３よりも大きい直径を有する大径部７４とを有する。プラグ挿入部２１へのプラグ７２の挿入時、小径部７３がパッキン３１と当接し、大径部７４が嵌合部１５に嵌め合わされる。 More specifically, the main body case 12 has a fitting portion 15 into which the plug 72 inserted into the plug insertion portion 21 is fitted. The fitting portion 15 is provided at a corner portion between the outer surface 13 and the first side wall portion 22. On the other hand, as shown in FIG. 3, the plug 72 has a small diameter portion 73 and a large diameter portion 74 having a diameter larger than that of the small diameter portion 73. When the plug 72 is inserted into the plug insertion portion 21, the small diameter portion 73 comes into contact with the packing 31, and the large diameter portion 74 is fitted into the fitting portion 15.
　このような構成により、大径部７４と嵌合部１５との間に、コイルばね３７からパッキン３１に作用する力よりも大きい摩擦力を生じさせ、バッテリ充電時にパッキン３１を第２位置に保持する。 With such a configuration, a frictional force larger than the force acting on the packing 31 from the coil spring 37 is generated between the large-diameter portion 74 and the fitting portion 15, and the packing 31 is held in the second position when the battery is charged. To do.
　本実施の形態における携帯型電話機１０においては、プラグ挿入部２１へのプラグ７２の挿入に伴って、パッキン３１がプラグ挿入部２１の開口を塞ぐ第１位置から電極部４２よりも奥まった第２位置に押し込まれるため、バッテリを充電するごとにパッキン３１を取り外す必要がない。このため、パッキン３１の劣化の進行を抑え、パッキン３１のシール部材としての機能を長期に渡って維持することができる。 In the mobile phone 10 according to the present embodiment, the second position where the packing 31 is deeper than the electrode portion 42 from the first position where the packing 31 closes the opening of the plug insertion portion 21 with the insertion of the plug 72 into the plug insertion portion 21. Since it is pushed into the position, it is not necessary to remove the packing 31 every time the battery is charged. For this reason, progress of deterioration of packing 31 can be suppressed and the function as a sealing member of packing 31 can be maintained over a long period of time.
　また、本実施の形態では、プラグ７２をプラグ挿入部２１に挿入する動作に連動して、電極部４２を電極部収容部１８からプラグ挿入部２１に進入させる。これにより、プラグ挿入部２１へのプラグ７２の挿入時に、プラグ７２と電極部４２とが干渉することを防ぐとともに、プラグ７２の挿入後には、電極部４２とプラグ７２とを接触させることができる。 Further, in the present embodiment, the electrode part 42 is caused to enter the plug insertion part 21 from the electrode part accommodating part 18 in conjunction with the operation of inserting the plug 72 into the plug insertion part 21. This prevents the plug 72 and the electrode portion 42 from interfering when the plug 72 is inserted into the plug insertion portion 21, and allows the electrode portion 42 and the plug 72 to contact each other after the plug 72 is inserted. .
　また、本実施の形態では、本体ケース１２に、プラス端子に対応するプラグ７２Ａが挿入されるプラグ挿入部２１Ａと、マイナス端子に対応するプラグ７２Ｂが挿入されるプラグ挿入部２１Ｂとが別々に設けられている。このような構成によれば、万が一プラグ挿入部２１Ａおよびプラグ挿入部２１Ｂのいずれか一方に水が侵入することがあっても短絡が生じるということがない。 In the present embodiment, the main body case 12 is provided with a plug insertion portion 21A into which the plug 72A corresponding to the plus terminal is inserted and a plug insertion portion 21B into which the plug 72B corresponding to the minus terminal is inserted. It has been. According to such a configuration, even if water enters one of the plug insertion portion 21A and the plug insertion portion 21B, a short circuit does not occur.
