Description

本発明は、防水機能を備えた電子機器に関する。 The present invention relates to an electronic device having a waterproof function.

近年、携帯電話機等の電子機器が防水機能を備えるようになってきたことに伴い、お風呂等の浸水する恐れのある場所で携帯電話機が使用される機会が増えている。防水機能を備えた携帯電話機において、充電端子は外部に露出させざるを得ない金属部品であるため、耐腐食性について考慮した設計をする必要がある。 In recent years, as electronic devices such as mobile phones have been provided with a waterproof function, the opportunities for using mobile phones in places where there is a risk of flooding such as baths are increasing. In a mobile phone having a waterproof function, the charging terminal is a metal part that must be exposed to the outside, and therefore, it is necessary to design it in consideration of corrosion resistance.

すなわち、携帯電話機が防水機能を備えていたとしても、充電端子等の金属部品が筐体の外部に露出していると、その露出した金属部品が腐食する恐れがあるため、外部に露出した金属部分に金メッキ処理、封孔処理等の防水処理を施すことによって、携帯電話機の充電端子等の金属部品を耐腐食性を有する状態に加工する必要がある。しかしながら、筐体から露出した金属部分に金メッキを施す際、金メッキ処理を行う領域が大きくなればなるほど、製造コストが高くなってしまうという問題があった。 That is, even if the mobile phone has a waterproof function, if metal parts such as charging terminals are exposed to the outside of the housing, the exposed metal parts may corrode. It is necessary to process a metal part such as a charging terminal of the mobile phone into a state having corrosion resistance by performing a waterproofing process such as a gold plating process or a sealing process on the part. However, when the metal portion exposed from the casing is subjected to gold plating, there is a problem that the manufacturing cost increases as the area for the gold plating process increases.

そこで、コストアップを招来することなく、内部に収容される充電池や保護回路等の電気部品を良好に保護することができる電子機器の保護ケースが提案されている（特許文献１参照）。この電子機器の保護ケースは、複数の電子部品が実装された保護回路とこの保護回路と導通する充電池とが樹脂製の容器に収容された充電池パックにおいて、保護回路または充電池とを導通するとともに、外部の所定の対象物と電気的な導通が可能とされた端子片を、容器に一体的にインサート成形したものである。
特開平１１−１８５７１９号公報 Therefore, a protective case for an electronic device has been proposed that can satisfactorily protect electrical components such as a rechargeable battery and a protection circuit accommodated therein without causing an increase in cost (see Patent Document 1). The protective case of the electronic device is a conductive battery pack in which a protective circuit in which a plurality of electronic components are mounted and a rechargeable battery that is electrically connected to the protective circuit are housed in a resin container. In addition, a terminal piece that can be electrically connected to a predetermined external object is integrally formed in a container by insert molding.

特許文献１に記載されているように端子片を外装筐体に一体的にインサート成形した場合、外装筐体の寸法にバラツキが生じやすいという問題があった。外装筐体の寸法にバラツキがあると、防水機能の信頼性が低下してしまう恐れがある。また、特許文献１の端子片（図４に示す第１端子片４）は、その構造上、スライド機構を有さない単純な金型構造においては金型から抜くことができないため、製造困難なものと思われる。さらに、特許文献１には基板（保護回路）の表面に形成された端子が端子片に接触することにより充電池と導通する構成が記載されているが、基板の寸法にはバラツキがあるため基板の端子が端子片に安定して接触する保証はなく、基板を支持部材として用いることは困難である。 As described in Patent Literature 1, when the terminal piece is integrally insert-molded with the exterior casing, there is a problem that the dimensions of the exterior casing are likely to vary. If there are variations in the dimensions of the exterior housing, the reliability of the waterproof function may be reduced. Further, the terminal piece (first terminal piece 4 shown in FIG. 4) of Patent Document 1 is difficult to manufacture because it cannot be removed from the mold in a simple mold structure having no slide mechanism. It seems to be. Furthermore, Patent Document 1 describes a configuration in which a terminal formed on the surface of a substrate (protection circuit) is brought into conduction with a rechargeable battery by contacting the terminal piece. It is difficult to use the substrate as a support member because there is no guarantee that the terminal of the terminal is in contact with the terminal piece stably.

本発明は、上記課題を鑑みなされてものであり、防水機能を備えた電子機器であって、防水機能の信頼性を損なわずに製造コストを削減することができる電子機器を提供することを目的とする。 The present invention has been made in view of the above problems, and an object thereof is to provide an electronic device having a waterproof function, which can reduce the manufacturing cost without impairing the reliability of the waterproof function. And

本発明に係る電子機器によると、充電端子ユニットを筐体とは別ピースとして形成し、露出する金属部分を少なくして金メッキの領域をできる限り小さくするとともに、防水用パッキンの嵌合部分を全て樹脂部材で形成することにより、防水機能の信頼性を損なわずに製造コストを削減することが可能となる。 According to the electronic device of the present invention, the charging terminal unit is formed as a separate piece from the housing, the exposed metal portion is reduced to reduce the gold plating area as much as possible, and all the fitting portions of the waterproof packing are provided. By forming the resin member, the manufacturing cost can be reduced without impairing the reliability of the waterproof function.

As an electronic apparatus according to the present invention, a clamshell mobile phone 1 in which a plurality of housings are connected so as to be openable and closable will be described as an example. FIG. 1 is a perspective view showing the cellular phone 1 in an opened state.

携帯電話機１は、図１に示すように、主に、矩形の板状の上筐体１０と、この上筐体１０とほぼ同形状をした下筐体１１とにより構成されていて、これらの上筐体１０及び下筐体１１は、閉じた状態において相互に一面を覆うように積層されている。上筐体１０及び下筐体１１は、ヒンジ部１２を挟むようにヒンジ結合されていて、上筐体１０は下筐体１１に対して、ヒンジ部１２を軸にして、図１のＸ方向に所定角度だけ回転自在なように形成されている。携帯電話機１は、上筐体１０を下筐体１１に対して回転させることにより、閉じた状態から開いた状態に、あるいは開いた状態から閉じた状態に変形する。 As shown in FIG. 1, the mobile phone 1 is mainly composed of a rectangular plate-shaped upper housing 10 and a lower housing 11 having substantially the same shape as the upper housing 10. The upper housing 10 and the lower housing 11 are laminated so as to cover one surface in a closed state. The upper housing 10 and the lower housing 11 are hinged so as to sandwich the hinge portion 12, and the upper housing 10 is relative to the lower housing 11 with the hinge portion 12 as an axis in the X direction of FIG. It is formed so as to be rotatable by a predetermined angle. The cellular phone 1 is transformed from a closed state to an open state or from an open state to a closed state by rotating the upper housing 10 with respect to the lower housing 11.

上筐体１０の内面（下筐体１１に対面する側の面）には、文字や画像等の情報を含んだ表示画面６０を表示するための液晶ディスプレイ１３、音声を出力するためのスピーカ１４が設けられている。これらの液晶ディスプレイ１３やスピーカ１４は、携帯電話機１が閉じた状態のときには、下筐体１１により覆われていて外部に露出していないが、上筐体１０を下筐体１１に対して回転させて開いた状態に変形させたときには、外部に露出される。 On the inner surface of the upper housing 10 (the surface facing the lower housing 11), a liquid crystal display 13 for displaying a display screen 60 including information such as characters and images, and a speaker 14 for outputting sound. Is provided. The liquid crystal display 13 and the speaker 14 are covered with the lower casing 11 and not exposed to the outside when the mobile phone 1 is closed, but the upper casing 10 is rotated with respect to the lower casing 11. When it is deformed into an open state, it is exposed to the outside.

下筐体１１の内面（上筐体１０に対面する側の面）には、例えば、カーソルや表示画面を上下左右に移動させるための十字キーや、項目を選択するための選択キーや、数字を入力するための数字キー、発信処理を行うための発信キー等の操作キー１５が設けられている。また下筐体１１には、音声を集音するためのマイクロフォン１６が設けられている。これらの操作キー１５やマイクロフォン１６は、携帯電話機１が閉じた状態のときには、上筐体１０により覆われていて外部に露出していないが、上筐体１０を下筐体１１に対して回転させて開いた状態に変形させたときには、外部に露出される。 On the inner surface of the lower housing 11 (the surface facing the upper housing 10), for example, a cross key for moving the cursor and display screen up and down, left and right, a selection key for selecting an item, and a number There are provided operation keys 15 such as a numeric key for inputting "a" and a transmission key for performing transmission processing. The lower casing 11 is provided with a microphone 16 for collecting sound. These operation keys 15 and microphone 16 are covered with the upper casing 10 and are not exposed to the outside when the cellular phone 1 is closed, but the upper casing 10 is rotated with respect to the lower casing 11. When it is deformed into an open state, it is exposed to the outside.

下筐体１１の側面には、外部バッテリの接続端子や充電器の接続端子を接続することにより、携帯電話機１に外部から電力を供給したり内蔵バッテリ６４の充電を行ったりするための充電端子ユニット１７が備えられている。充電端子ユニット１７は、携帯電話機１が閉じた状態のときでも開いた状態のときでも外部に露出されているため、いつでも外部バッテリの接続端子や充電器の接続端子を接続することができる。 A charging terminal for supplying power to the mobile phone 1 from the outside or charging the built-in battery 64 by connecting a connection terminal of an external battery or a connection terminal of a charger to the side surface of the lower housing 11. A unit 17 is provided. Since the charging terminal unit 17 is exposed to the outside even when the cellular phone 1 is in the closed state or the opened state, the connection terminal of the external battery or the connection terminal of the charger can be connected at any time.

充電端子ユニット１７は、金属材料で形成されるとともに常に携帯電話機１の外部に露出している部品であるため、携帯電話機１が防水機能を備えるためには、この充電端子ユニット１７に対して耐腐食性を考慮した設計をするとともに、下筐体１１の内部への浸水を防止する必要がある。そこで、本発明の携帯電話機１において、充電端子ユニット１７を下筐体１１とは別ピースとして形成するとともに、充電端子ユニット１７の金属部分の一部のみを下筐体１１から露出させ、また、ゴムパッキン（後述するゴム部材２３）を使用して下筐体１１の内部の浸水を防止することで、信頼性の高い防水機能と実現させている。 Since the charging terminal unit 17 is formed of a metal material and is always exposed to the outside of the mobile phone 1, the charging terminal unit 17 is resistant to the charging terminal unit 17 in order to have a waterproof function. It is necessary to design in consideration of corrosiveness and to prevent water from entering the lower housing 11. Therefore, in the mobile phone 1 of the present invention, the charging terminal unit 17 is formed as a separate piece from the lower casing 11, and only a part of the metal portion of the charging terminal unit 17 is exposed from the lower casing 11, By using a rubber packing (rubber member 23 described later) to prevent water in the lower casing 11 from being flooded, a highly reliable waterproof function is realized.

一対の舌片４１において、平板部４０に対抗する側の面には、矩形状の溝部４９がそれぞれ設けられているとともに、これらの溝部４９の中央部にはそれぞれ円形の貫通孔５０が設けられている。溝部４９は、第１の金属部材２０及び第２の金属部材２１の第３の平板部３３と同形状に形成されており、第１の金属部材２０及び第２の金属部材２１が樹脂部材２２に嵌め込まれる際、第１の金属部材２０及び第２の金属部材２１の第３の平板部３３がそれぞれ舌片４１の溝部４９に嵌め込まれる。この際、樹脂部材２２において、円形の貫通孔５０を介して、嵌め込まれた金属部材２０、２１の第３の平板部がそれぞれ露出する。 In the pair of tongue pieces 41, rectangular grooves 49 are provided on the surface facing the flat plate portion 40, and circular through holes 50 are provided in the center of these grooves 49. ing. The groove portion 49 is formed in the same shape as the third flat plate portion 33 of the first metal member 20 and the second metal member 21, and the first metal member 20 and the second metal member 21 are the resin member 22. The third flat plate portion 33 of the first metal member 20 and the second metal member 21 is fitted into the groove portion 49 of the tongue piece 41, respectively. At this time, in the resin member 22, the third flat plate portions of the fitted metal members 20 and 21 are exposed through the circular through hole 50.

また、一対の舌片４１のうちの一方（第２の金属部材２１に当接する方）の溝部４９の外縁において、樹脂部材２２の平板部４０の短辺方向の２辺には切込部５１が設けられていて、樹脂部材２２に第２の金属部材２１を嵌め込む際、第２の金属部材２１の第３の平板部３３の一対の係止片３７が、これらの切込部５１をそれぞれ貫通する。 Further, at the outer edge of the groove portion 49 of one of the pair of tongue pieces 41 (the one contacting the second metal member 21), cut portions 51 are formed on two sides in the short side direction of the flat plate portion 40 of the resin member 22. When the second metal member 21 is fitted into the resin member 22, the pair of locking pieces 37 of the third flat plate portion 33 of the second metal member 21 causes these cut portions 51 to be inserted. Each penetrates.

これらの第１の金属部材２０、第２の金属部材２１、樹脂部材２２、ゴム部材２３を用いて充電端子ユニット１７を作成する際、図７（Ａ）に示すように、樹脂部材２２の平板部４０の外面４０ａの内側切込部４５に第１の金属部材２０及び第２の金属部材２１の連結部３１が位置するように、樹脂部材２２に第１の金属部材２０及び第２の金属部材２１が組み込まれ、この外面４０ａの溝部４４に第１の金属部材２０及び第２の金属部材２１の第１の平板部３０がそれぞれ嵌め込まれる。 When the charging terminal unit 17 is formed using the first metal member 20, the second metal member 21, the resin member 22, and the rubber member 23, as shown in FIG. The first metal member 20 and the second metal are disposed on the resin member 22 so that the connecting portion 31 of the first metal member 20 and the second metal member 21 is positioned in the inner cut portion 45 of the outer surface 40a of the portion 40. The member 21 is incorporated, and the first metal member 20 and the first flat plate portion 30 of the second metal member 21 are fitted into the groove portions 44 of the outer surface 40a.

また、図７（Ｂ）に示すように、樹脂部材２２の平板部４０の内面４０ｂの溝部４７に第１の金属部材２０及び第２の金属部材２１の第２の平板部３２が嵌め込まれる。この際、第１の金属部材２０及び第２の金属部材２１の第３の平板部３３は、樹脂部材２２の舌片４１の溝部４９に嵌め込まれる。また、リング状のゴム部材２３が樹脂部材２２の平板部４０の外側面を全周囲に渡って覆うように、台部４６に嵌められる。 As shown in FIG. 7B, the first flat plate portion 32 of the first metal member 20 and the second metal member 21 is fitted into the groove portion 47 of the inner surface 40 b of the flat plate portion 40 of the resin member 22. At this time, the third flat plate portion 33 of the first metal member 20 and the second metal member 21 is fitted into the groove portion 49 of the tongue piece 41 of the resin member 22. Further, the ring-shaped rubber member 23 is fitted to the base portion 46 so as to cover the outer surface of the flat plate portion 40 of the resin member 22 over the entire circumference.

これにより、図７（Ａ）及び図７（Ｃ）に示すように、樹脂部材２２の外面４０ａから第１の金属部材２０及び第２の金属部材２１の第１の平板部３０がそれぞれ露出する。また、図７（Ｂ）及び図７（Ｃ）に示すように、樹脂部材２２の内面４０ｂから第１の金属部材２０及び第２の金属部材２１の第２の平板３２及び第３の平板３３がそれぞれ露出する。また、露出した第１の金属部材２０及び第２の金属部材２１の第１の平板部３０、及び露出した第１の金属部材２０及び第２の金属部材２１の第２の平板部３２の間の位置に、ゴム部材２３が固定される。よって、充電端子ユニット１７において、外部に露出する金属部分は、金属部材２０、２１の第１の平面部３０、第２の平面部３２、第３の平面部３３のみとなる。 As a result, as shown in FIGS. 7A and 7C, the first flat plate portions 30 of the first metal member 20 and the second metal member 21 are exposed from the outer surface 40a of the resin member 22, respectively. . Further, as shown in FIGS. 7B and 7C, the second flat plate 32 and the third flat plate 33 of the first metal member 20 and the second metal member 21 from the inner surface 40b of the resin member 22 are used. Are exposed. Further, between the exposed first flat plate portion 30 of the first metal member 20 and the second metal member 21 and the exposed second flat plate portion 32 of the first metal member 20 and the second metal member 21. The rubber member 23 is fixed at the position. Therefore, in the charging terminal unit 17, the metal portions exposed to the outside are only the first plane portion 30, the second plane portion 32, and the third plane portion 33 of the metal members 20 and 21.

このように形成された充電端子ユニット１７は、図８に示すように、下筐体１１の内部に組み込まれる。下筐体１１は、内側側面の所定位置に、充電端子ユニット１７の樹脂部材２２の平板部４０と同形状（樹脂部材２２を収容する形状）に、一対の窓部１８を内部に含むように形成された溝部１９を備えている。また下筐体１１は、内側底面の所定位置に所定サイズで設けられた溝部１９ａを備えている。充電端子ユニット１７は、下筐体１１の内側側面の溝部１９に、第１の金属部材２０、第２の金属部材２１の第１の平板部３０がそれぞれ窓部１８に当接するような状態で嵌め込まれる。これにより、下筐体１１に充電端子ユニット１７が嵌め込まれた状態において、金属部材２０、２１の第１の平板部３０が下筐体１１の窓部１８からそれぞれ露出する。外部バッテリや充電器の接続端子を、下筐体１１の窓部１８から露出した第１の平板部３０に接触させることにより、携帯電話機１に対する電力の供給が行われる。 The charging terminal unit 17 formed in this way is incorporated into the lower housing 11 as shown in FIG. The lower housing 11 includes a pair of window portions 18 at a predetermined position on the inner side surface in the same shape as the flat plate portion 40 of the resin member 22 of the charging terminal unit 17 (a shape that accommodates the resin member 22). A formed groove 19 is provided. In addition, the lower housing 11 includes a groove portion 19a provided in a predetermined size at a predetermined position on the inner bottom surface. The charging terminal unit 17 is in a state in which the first flat plate portion 30 of the first metal member 20 and the second metal member 21 is in contact with the window portion 18 in the groove portion 19 on the inner side surface of the lower housing 11. It is inserted. Thereby, in a state where the charging terminal unit 17 is fitted in the lower housing 11, the first flat plate portions 30 of the metal members 20 and 21 are respectively exposed from the window portion 18 of the lower housing 11. By connecting the connection terminal of the external battery or the charger to the first flat plate portion 30 exposed from the window portion 18 of the lower housing 11, power is supplied to the mobile phone 1.

またこの際、樹脂部材２２の外周（外側面）部分に嵌め込まれたゴム部材２３が下筐体１１の溝部１９に隙間なく密着するように当接することにより、ゴム部材２３は防水用パッキンの役割を果たし、窓部１８を介して下筐体１１の内部に水が浸入することが防止される。 At this time, the rubber member 23 fitted into the outer peripheral (outer side) portion of the resin member 22 contacts the groove portion 19 of the lower housing 11 so as to be in close contact with each other, so that the rubber member 23 serves as a waterproof packing. This prevents water from entering the lower housing 11 through the window 18.

充電端子ユニット１７が下筐体１１に嵌め込まれた後、充電端子ユニット１７は固定部材６０で更に固定される。すなわち、この固定部材６０は突出部６１を備えていて、この突出部６１が充電端子ユニット１７を外部方向に押し付けるように当接し、突出部６１ａが下筐体１１の内側底面に設けられた溝部１９ａに嵌め込まれることにより、充電端子ユニット１７を下筐体１１に固定する。これにより、充電端子ユニット１７は下筐体１１と固定部材６０とで押さえつけられ、下筐体１１に強い水圧が加わった場合や下筐体１１が強く揺さぶられた場合であっても、位置がずれることがない。 After the charging terminal unit 17 is fitted into the lower housing 11, the charging terminal unit 17 is further fixed by the fixing member 60. That is, the fixing member 60 includes a protrusion 61, the protrusion 61 abuts on the charging terminal unit 17 so as to press it outward, and the protrusion 61 a is a groove provided on the inner bottom surface of the lower housing 11. The charging terminal unit 17 is fixed to the lower housing 11 by being fitted into 19a. As a result, the charging terminal unit 17 is pressed by the lower casing 11 and the fixing member 60, and even when a strong water pressure is applied to the lower casing 11 or when the lower casing 11 is shaken strongly, the position is maintained. There is no deviation.

さらに、充電端子ユニット１７が固定部材６０により固定された後、図９に示すように、基板部材６２が下筐体１１の内部に組み込まれる。この際、基板部材６２に設けられた突起部６３が、下筐体１１の内部に組み込まれている充電端子ユニット１７を外部方向に押し付けるように当接することにより、充電端子ユニット１７は、固定部材６０に加えて基板部材６２により二重に固定される。 Further, after the charging terminal unit 17 is fixed by the fixing member 60, the substrate member 62 is incorporated into the lower housing 11 as shown in FIG. 9. At this time, the protrusion 63 provided on the board member 62 abuts the charging terminal unit 17 incorporated in the lower housing 11 so as to press it outward, so that the charging terminal unit 17 is fixed to the fixing member. In addition to 60, the substrate member 62 is fixed in a double manner.

一般的に、基板の寸法はバラツキが生じやすい。充電端子ユニット１７がゴム部材２３を有さずに剛体だけで形成されている場合は、剛体である基板と剛体同士で接触することになるため、基板を支持部材として使用するためにはシビアな寸法管理や調整が必要となってしまう。しかしながら、本発明の携帯電話機１では、下筐体１１の溝部１９の外周に充電端子ユニット１７のゴム部材２３を密着させて固定するため、基板部材６２の寸法に多少のバラツキが生じた場合であっても、ゴム部材２３の弾性を利用してそのバラツキを吸収して基板部材６２で充電端子ユニット１７を固定することが可能となる。 In general, the substrate dimensions tend to vary. When the charging terminal unit 17 is formed of only a rigid body without having the rubber member 23, the rigid body substrate and the rigid body are in contact with each other, so that it is severe to use the substrate as a support member. Dimension management and adjustment are required. However, in the mobile phone 1 of the present invention, the rubber member 23 of the charging terminal unit 17 is fixed in close contact with the outer periphery of the groove portion 19 of the lower housing 11, so that the substrate member 62 has some variation in dimensions. Even if it exists, it becomes possible to absorb the variation using the elasticity of the rubber member 23 and to fix the charging terminal unit 17 with the board member 62.

そして、図１０（Ａ）乃至図１０（Ｃ）に示すように、さらに下筐体１１の内部において、基板部材６２の上部に内蔵バッテリ６４が収納される。この内蔵バッテリ６４の接続端子が充電端子ユニット１７の第３の平板部３３に接触することで、第１の平板部材３１に接続された外部バッテリや充電器等から内蔵バッテリ６４に電力が供給される。 Then, as shown in FIGS. 10A to 10C, a built-in battery 64 is housed in the upper portion of the board member 62 inside the lower housing 11. When the connection terminal of the internal battery 64 comes into contact with the third flat plate portion 33 of the charging terminal unit 17, electric power is supplied to the internal battery 64 from an external battery, a charger, or the like connected to the first flat plate member 31. The

このように、充電端子ユニット１７が下筐体１１に組み込まれた状態で、下筐体１１が浸水した場合、下筐体１１の溝部１９の外周に密着したゴム部材２３によって下筐体１１の内部に水が浸入するのが食い止められるため、図１１に示すように、充電端子ユニット１７のゴム部材２３を境に、下筐体１１の外側（第１の平板部３０の側）は水没するが、下筐体１１の内側（第２の平板部３２及び第３の平板部３３の側）は水没することが防止されている。 As described above, when the lower housing 11 is submerged in a state where the charging terminal unit 17 is incorporated in the lower housing 11, the rubber member 23 that is in close contact with the outer periphery of the groove portion 19 of the lower housing 11 is used. Since water is prevented from entering the inside, as shown in FIG. 11, the outer side of the lower housing 11 (the first flat plate portion 30 side) is submerged with the rubber member 23 of the charging terminal unit 17 as a boundary. However, the inner side of the lower housing 11 (the second flat plate portion 32 and the third flat plate portion 33 side) is prevented from being submerged.

充電端子ユニット１７において、樹脂部材２２から露出している金属部分は、第１の金属部材２０及び第２の金属部材２１の第１の平板部３０、第２の平板部３２、第３の平板部３３であり、また、充電端子ユニット１７が下筐体１１に嵌め込まれた際に、これらの金属部分のうちのゴム部材２３よりも外側（水没する側）において露出している部分は、第１の平板部３０に限定されるため、この第１の平板部３０にのみ、腐食を防ぐために、例えば金メッキ等のメッキ処理を行えば良い。 In the charging terminal unit 17, the metal portions exposed from the resin member 22 are the first flat plate portion 30, the second flat plate portion 32, and the third flat plate of the first metal member 20 and the second metal member 21. When the charging terminal unit 17 is fitted into the lower housing 11, the portion of the metal portion that is exposed outside (submerged in) the rubber member 23 is the first portion 33. Since it is limited to one flat plate portion 30, only the first flat plate portion 30 may be subjected to a plating process such as gold plating in order to prevent corrosion.

なお、第１の金属部材２０及び第２の金属部材２１の形状はこれに限定されず、第１の平板部３０が下筐体１１の外部に露出し、第２の平板部３２または第３の平板部３３が下筐体１１の内部に露出するような形状なら、任意の形状に形成されて良い。 Note that the shapes of the first metal member 20 and the second metal member 21 are not limited to this, and the first flat plate portion 30 is exposed to the outside of the lower housing 11, and the second flat plate portion 32 or the third metal member 21 is exposed. As long as the flat plate portion 33 is exposed to the inside of the lower housing 11, it may be formed in an arbitrary shape.

また、防水用パッキンとしての役割を担うゴム部材２３が携帯電話機１において嵌合する部位が、全て樹脂材料（樹脂部材２２の台部４６）で形成されることにより、このゴム部材２３を充電端子ユニット１７に嵌め込む際、または、充電端子ユニット１７を下筐体１１に組み込む際に、ゴム部材２３に傷を付けてしまう可能性が小さくなり、防水機能の信頼性を向上させることが可能となる。 Further, all the parts where the rubber member 23 serving as a waterproof packing fits in the cellular phone 1 are formed of a resin material (the base portion 46 of the resin member 22). When fitting into the unit 17 or when incorporating the charging terminal unit 17 into the lower casing 11, the possibility of scratching the rubber member 23 is reduced, and the reliability of the waterproof function can be improved. Become.

本発明に係る電子機器（携帯電話機１）によると、充電端子ユニット１７を下筐体１１とは別ピースとして形成するとともに、ゴムパッキン（ゴム部材２３）を用いて筐体１１の内部への浸水を防止し、充電端子ユニット１７において水没する恐れのある金属部分を少なくすることにより、金メッキを行う領域をできる限り少なくすることができる。これにより、防水機能を備えた携帯電話機１の製造コストを大幅に削減することが可能となる。また、防水用パッキンとなるゴム部材２３の嵌合部分を全て樹脂部材２２で形成することにより、防水機能の信頼性を高めることができる。 According to the electronic device (mobile phone 1) according to the present invention, the charging terminal unit 17 is formed as a separate piece from the lower casing 11, and water is immersed into the casing 11 using the rubber packing (rubber member 23). By preventing the metal portion that is likely to be submerged in the charging terminal unit 17, it is possible to reduce the region where gold plating is performed as much as possible. Thereby, the manufacturing cost of the mobile phone 1 having a waterproof function can be greatly reduced. Moreover, the reliability of the waterproof function can be improved by forming all the fitting portions of the rubber member 23 to be the waterproof packing with the resin member 22.

また、本発明に係る電子機器（携帯電話機１）によると、固定部材６０を用いて充電端子ユニット１７を下筐体１１に固定することにより、電子機器に強い水圧が加わった場合や電子機器が強く揺さぶられた場合であっても、充電端子ユニット１７の位置がずれることが防止される。さらに、基板部材６２において充電端子ユニット１７に当接する突起部６３を設けて、この基板部材６２を充電端子ユニット１７に当接させることにより充電端子ユニット１７を下筐体１１に固定することで、充電端子ユニット１７を下筐体１１の内部に強固に固定することが可能となる。 In addition, according to the electronic device (mobile phone 1) according to the present invention, the charging terminal unit 17 is fixed to the lower casing 11 using the fixing member 60, so that a strong water pressure is applied to the electronic device or the electronic device is Even when it is strongly shaken, the position of the charging terminal unit 17 is prevented from shifting. Furthermore, by providing a protrusion 63 that contacts the charging terminal unit 17 in the board member 62 and fixing the charging terminal unit 17 to the lower housing 11 by bringing the board member 62 into contact with the charging terminal unit 17, The charging terminal unit 17 can be firmly fixed inside the lower housing 11.
