Description

この発明は携帯電子機器のスイッチ作動用ゴムキーの防水構造に関する。   The present invention relates to a waterproof structure for a rubber key for operating a switch of a portable electronic device.

従来の携帯電子機器のスイッチ作動用ゴムキーの防水構造の例を図５〜図７により説明かる。図５に示す１は無線機外付け用スピーカマイク（スピーカおよびマイクロホンが単一のケースに収納されたもの）のケースであり、可動つまみ１が設けられている。可動つまみ１はＰＴＴ（PUSH to talk) として動作するものであり、これを押すことによりマイクロホンが作動状態となる。   An example of a waterproof structure of a conventional rubber key for operating a switch of a portable electronic device will be described with reference to FIGS. Reference numeral 1 shown in FIG. 5 is a case of a speaker microphone for external radio (a speaker and a microphone housed in a single case), and a movable knob 1 is provided. The movable knob 1 operates as PTT (PUSH to talk), and when this is pressed, the microphone is activated.

可動つまみ１は図５、図６に矢印で示すように回動中心軸５ａ回りに回動し、図示していないプリント基板に実装されたタクトスイッチ２をスイッチ作動用ゴムキー６を介して作動させる。スイッチ作動用ゴムキー６は図７に詳しく示すように、円筒形状の固定部６ｃの前後に夫々フランジ６ｄ、６ｄが形成され、さらに、固定部６ｃの内面にヒンジ６ｂ（図６）を介して作動杆６ａが一体に形成されたものであり、可動つまみ１により作動杆６ａが動かされタクトスイッチ２が作動する。   The movable knob 1 rotates about the rotation center axis 5a as shown by the arrows in FIGS. 5 and 6, and the tact switch 2 mounted on the printed circuit board (not shown) is operated via the switch operating rubber key 6. . As shown in detail in FIG. 7, the switch operating rubber key 6 is formed with flanges 6d and 6d on the front and rear sides of the cylindrical fixing portion 6c, respectively, and is further operated on the inner surface of the fixing portion 6c via a hinge 6b (FIG. 6). The rod 6a is integrally formed, and the actuating rod 6a is moved by the movable knob 1 to operate the tact switch 2.

図７の矢印で示すように、スイッチ作動用ゴムキー６をケース１の穴１ａに押し込み図６に示すようにフランジ６ｄの全周をボンド１１でケース１に固定することでスイッチ作動用ゴムキー６がケース１に固定される。また、ボンド１１はケース１の穴１ａの防水機能を果たし、ケース１へ水が侵入することが防止される。   As shown by the arrow in FIG. 7, the switch operating rubber key 6 is pushed into the hole 1a of the case 1 and the entire circumference of the flange 6d is fixed to the case 1 with a bond 11 as shown in FIG. Fixed to case 1. Further, the bond 11 fulfills the waterproof function of the hole 1a of the case 1 and prevents water from entering the case 1.

上記スイッチ作動用ゴムキーの防水構造によると、ボンドによりスイッチ作動用ゴムキー６をケース１に固定してしまうため、スイッチ作動用ゴムキー６が適切な位置に固定されなかったりするため、組立てが面倒であり、製造コストが高くなるという問題がぁつた。さらに、スイッチ作動用ゴムキー６またはケース１の一方が破損した場合に、その一方のみを交換することが不可能であり、保守のコストが高くなるという問題あった。   According to the waterproof structure of the switch operation rubber key, the switch operation rubber key 6 is fixed to the case 1 by bonding, and the switch operation rubber key 6 is not fixed at an appropriate position, so that the assembly is troublesome. There was a problem of high manufacturing costs. Furthermore, when one of the switch operating rubber key 6 or the case 1 is damaged, it is impossible to replace only one of them, resulting in an increase in maintenance costs.

図８に示す従来の携帯電子機器のスイッチ作動用ゴムキーの防水構造の他の例では、プリント基板４にメンブレンスイッチ３が設けられており、ゴム５ｂが貼着された可動つまみ５が防水シート１２を介してメンブレンスイッチ３を作動させる。防水シート１２には両面テープ１２ａが貼付けられており、防水シート１２が両面テープ１２ａによりケース１に貼付けられ、ケース１の穴から水が入ることが防止される。   In another example of the waterproof structure of the switch operating rubber key of the conventional portable electronic device shown in FIG. 8, the membrane switch 3 is provided on the printed circuit board 4, and the movable knob 5 with the rubber 5 b attached is the waterproof sheet 12. The membrane switch 3 is operated via Double-sided tape 12 a is affixed to the waterproof sheet 12, and the waterproof sheet 12 is affixed to the case 1 with the double-sided tape 12 a, and water is prevented from entering through the holes in the case 1.

上記スイッチ作動用ゴムキーの防水構造によると、ゴム部品とスイッチの間に両面テープ付防水シートが別部品として必要であり、また、防水シートが剥がれないように何かで押えつけておく必要があり、部品点数および組立て工数が増大してコスト増大要因となっていた。また、防水シートを介してスイッチを作動させるため、スイッチのクリック感を損ねるという問題があった。   According to the waterproof structure of the switch operation rubber key, a waterproof sheet with double-sided tape is required as a separate part between the rubber part and the switch, and it is necessary to hold it in place so that the waterproof sheet does not peel off. As a result, the number of parts and the number of assembling steps have increased, which has been a factor in increasing costs. Further, since the switch is operated via the waterproof sheet, there is a problem that the click feeling of the switch is impaired.

図９〜図１１に従来の携帯電子機器のスイッチ作動用ゴムキーの防水構造のさらに他の例を示す。図９は従来の携帯電子機器のスイッチ作動用ゴムキーの防水構造のさらに他の例を示す分解斜視図、図１０は同スイッチ作動用ゴムキーの防水構造を示す分解断面図、図１１は同スイッチ作動用ゴムキーの防水構造を示す断面図である。   9 to 11 show still another example of a waterproof structure for a rubber key for switch operation of a conventional portable electronic device. FIG. 9 is an exploded perspective view showing still another example of a waterproof structure for a switch operating rubber key of a conventional portable electronic device, FIG. 10 is an exploded sectional view showing the waterproof structure of the switch operating rubber key, and FIG. It is sectional drawing which shows the waterproof structure of the rubber key for water.

この例では図５〜図７で説明した従来の例におけるスイッチ作動用ゴムキー６がボンドによりケース１に固定されるのではなく、スイッチ作動用ゴムキー６のフランジ６ｄがケース１にボンドにより固定されるのではなく、固定部６ｃの外周面に設けられた防水リブ６ｅがゴムの弾力によりケース１の穴１ａの内周面に圧接されることにより防水機能を得ている。他の構成は図５〜図７に説明したものと同様であり、同一の機能を有する部材に同一の符号を付して詳細な説明を省略する。   In this example, the switch operating rubber key 6 in the conventional example described in FIGS. 5 to 7 is not fixed to the case 1 by bonding, but the flange 6d of the switch operating rubber key 6 is fixed to the case 1 by bonding. Instead, the waterproof rib 6e provided on the outer peripheral surface of the fixed portion 6c is pressed against the inner peripheral surface of the hole 1a of the case 1 by the elasticity of rubber, thereby obtaining a waterproof function. Other configurations are the same as those described with reference to FIGS. 5 to 7, members having the same functions are denoted by the same reference numerals, and detailed description thereof is omitted.

上記スイッチ作動用ゴムキーの防水構造では、防水リブ６ｅが円筒形状の固定部６ｃのゴム弾力でケース１の穴１ａの内周面に圧接されるため、圧接力を十分に大きくすることができず、ある限度を越える水圧に耐えられないという問題があった。   In the waterproof structure of the switch operating rubber key, the waterproof rib 6e is pressed against the inner peripheral surface of the hole 1a of the case 1 by the rubber elasticity of the cylindrical fixing portion 6c, so that the pressing force cannot be sufficiently increased. There was a problem that it could not withstand water pressure exceeding a certain limit.

特開平９−３０５２８１号公報に提案された防水構造では、キーボードの外面に沿うように成形された弾性体の防水カバー４３がその周囲に形成されたパッキン部４６をキーボードのサポートパネル４１とサポートベース４２で強圧させることで防水空間を形成し、防水空間内のキーボードの防水機能を得ている。   In the waterproof structure proposed in Japanese Patent Laid-Open No. 9-305281, a packing portion 46 formed around the outer surface of the keyboard and formed of an elastic waterproof cover 43 is formed around the keyboard support panel 41 and the support base. The waterproof space is formed by applying a strong pressure at 42, and the waterproof function of the keyboard in the waterproof space is obtained.

この防水構造では多くのキースイッチの防水機能を１つの防水カバー４３で得ているが、防水カバーが大きいため、部品コストをおよび組立て工数が増大し、単体のスイッチの防水構造には適していない。
特開平９−３０５２８１号公報、段落００２４〜段落００３８、図１〜図４ In this waterproof structure, the waterproof function of many key switches is obtained by one waterproof cover 43. However, since the waterproof cover is large, the parts cost and the number of assembling steps increase, and it is not suitable for the waterproof structure of a single switch. .
JP-A-9-305281, paragraphs 0024 to 0038, FIGS. 1 to 4

この発明は上記した点に鑑みてなされたものであって、その目的とするところは、単体のスイッチの作動に適し、製造および保守のコストが安く、しかも高いレベルの防水機能が得られる携帯電子機器のスイッチ作動用ゴムキーの防水構造を提供することにある。また、この発明の他の目的はスイッチを作動させるクリック感が得られ、スイッチを確実に作動させることができる携帯電子機器のスイッチ作動用ゴムキーの防水構造を提供することである。   The present invention has been made in view of the above points, and its object is to provide a portable electronic device that is suitable for the operation of a single switch, has low manufacturing and maintenance costs, and provides a high level waterproof function.

以下この発明を実施するための最良の形態を実施例に即して説明する。   The best mode for carrying out the present invention will be described below with reference to examples.

図１はこの発明の実施例１である携帯電子機器のスイッチ作動用ゴムキーの防水構造を示す分解斜視図、図２は同スイッチ作動用ゴムキーの防水構造を示す断面図である。   1 is an exploded perspective view showing a waterproof structure of a switch operating rubber key of a portable electronic device according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view showing the waterproof structure of the switch operating rubber key.

図１および図２に示すスイッチ作動用ゴムキー６は固定部６ｃの外周面に凹部６ｆが形成されている。そして、図１に矢印で示すようにケース１の穴１ａに嵌め込まれた後、ボンドでケース１に固定されないが、固定部６ｃの前後端に形成されたフランジ６ｄ、６ｄがケース１の表裏面を係止することで位置決めされる。   The switch operating rubber key 6 shown in FIGS. 1 and 2 has a recess 6f formed on the outer peripheral surface of the fixed portion 6c. Then, as shown by the arrows in FIG. 1, the flanges 6 d and 6 d formed at the front and rear ends of the fixing portion 6 c are not fixed to the case 1 by bonding after being fitted into the holes 1 a of the case 1. It is positioned by locking.

このスイッチ作動用ゴムキー６に樹脂製または金属製の剛体リング７が押し込まれ剛体リング７の外周面に形成された凸部７ａがスイッチ作動用ゴムキー６の外周面に凹部６ｆに嵌まり込むことにより剛体リング７の抜け止めがなされる。他の構成は図９で説明したものと同様であり、同一の機能を有する部材に同一の符号を付して詳細な説明を省略する。   A resin-made or metal-made rigid ring 7 is pushed into the switch operating rubber key 6, and a convex portion 7 a formed on the outer peripheral surface of the rigid ring 7 is fitted into the concave portion 6 f on the outer peripheral surface of the switch operating rubber key 6. The rigid ring 7 is prevented from coming off. Other configurations are the same as those described with reference to FIG. 9, and members having the same functions are denoted by the same reference numerals and detailed description thereof is omitted.

この例では、スイッチ作動用ゴムキー６の固定部６ｃが剛体リング７により内側から外側方向に押されるため、防水リブ６ｅがケース１の穴１ａ内面に強く圧接され、ＩＰ−＊７防水レベル（ＪＩＳ保護等級７級）の高い防水機能が得られた。また、スイッチ作動用ゴムキー６がケース１にボンドで固定されていないため、分解が容易であり、保守および分別廃棄が低コストで行える。   In this example, since the fixing portion 6c of the switch operating rubber key 6 is pushed from the inside to the outside by the rigid ring 7, the waterproof rib 6e is strongly pressed against the inner surface of the hole 1a of the case 1, and the IP- * 7 waterproof level (JIS A waterproof function with a high protection grade of 7) was obtained. Further, since the switch operating rubber key 6 is not fixed to the case 1 with a bond, disassembly is easy, and maintenance and separation and disposal can be performed at low cost.

図３（ａ）はこの発明の実施例２である携帯電子機器のスイッチ作動用ゴムキーの防水構造を示す断面図、図３（ｂ）は同防水構造を示す部分斜視図である。この例では、剛体リング８にフランジ８ａが形成されており、外周面の凸部が形成されていない。この例では可動つまみ５と剛体リング８のフランジ８ａの間にクッション９が圧縮状態で介装されている。クッション９により剛体リング８の抜け止めがなされる。他の構成は実施例１で説明したものと同様であり、同一の機能を有する部材に同一の符号を付して詳細な説明を省略する。   3A is a cross-sectional view showing a waterproof structure of a switch operating rubber key of a portable electronic device according to Embodiment 2 of the present invention, and FIG. 3B is a partial perspective view showing the waterproof structure. In this example, the flange 8a is formed in the rigid ring 8, and the convex part of the outer peripheral surface is not formed. In this example, a cushion 9 is interposed between the movable knob 5 and the flange 8a of the rigid ring 8 in a compressed state. The cushion 9 prevents the rigid ring 8 from coming off. Other configurations are the same as those described in the first embodiment, and members having the same functions are denoted by the same reference numerals and detailed description thereof is omitted.

この例は実施例１と同様の効果が得られるが、さらに、実施例１の剛体リング７の凸部７ａを設けるスペースがないときに有効に適用される。   This example can obtain the same effect as that of the first embodiment, but is also effectively applied when there is no space for providing the convex portion 7a of the rigid ring 7 of the first embodiment.

図４はこの発明の実施例３である携帯電子機器のスイッチ作動用ゴムキーの防水構造を示す断面図である。この例では、可動つまみと剛体リング８のフランジ８ａの間にスプリング１０が圧縮状態で介装されている。スプリング１０により剛体リング８の抜け止めがなされる。他の構成は実施例２で説明したものと同様であり、同一の機能を有する部材に同一の符号を付して詳細な説明を省略する。この例によっても実施例２と同様の効果が得られる。   4 is a cross-sectional view showing a waterproof structure of a switch operating rubber key of a portable electronic device which is Embodiment 3 of the present invention. In this example, a spring 10 is interposed between the movable knob and the flange 8a of the rigid ring 8 in a compressed state. The spring 10 prevents the rigid ring 8 from coming off. Other configurations are the same as those described in the second embodiment, and members having the same functions are denoted by the same reference numerals and detailed description thereof is omitted. The effect similar to Example 2 is acquired also by this example.

実施例は以上のように構成されているが発明はこれに限られず、例えば、タクトスイッチを用いることなく、プリント基板に設けたメンブレンをスイッチ作動用ゴムキーの作動杆で作動させてもよい。また、プリント基板に設けた導体パターンをスイッチ作動用ゴムキーの作動杆に設けた導体膜で導通させるようにしてもよい。   The embodiment is configured as described above, but the invention is not limited to this. For example, a membrane provided on a printed circuit board may be operated by an operating rod of a switch operating rubber key without using a tact switch. Alternatively, the conductor pattern provided on the printed circuit board may be made conductive by a conductor film provided on the switch operating rubber key.
