In recent years, an LED (light emitting diode) is used as a notification means for notifying a user of an incoming call or a warning by light in an electronic device such as a mobile phone, a PDA, a digital camera, a digital video camera, or a personal computer (for example, Patent Document 1).

ところで、この種の電子機器のユーザーが帯電した状態で筐体に触れると、筐体とLEDカバーとの隙間からその静電気が筐体内に流れ込むことがある。そして、筐体内に流れ込んだ静電気は最も近くにある導体に流れ易く、例えば、流れ込んだ先が回路基板上のグランド用の導体パターン(導体配線)である場合には問題は生じないが、静電気がLEDに流れ込んだ場合には、LEDや、このLEDと電気的に接続された他の電気部品や電子部品に高電圧の電流が流れ、LEDや他の電気部品や電子部品が破損するといった課題があった。   By the way, when a user of this type of electronic device touches the casing in a charged state, the static electricity may flow into the casing through a gap between the casing and the LED cover. Static electricity that has flowed into the housing tends to flow to the nearest conductor. For example, if the flow point is a ground conductor pattern (conductor wiring) on the circuit board, there is no problem. When the LED flows into the LED, there is a problem that a high voltage current flows through the LED and other electrical components and electronic components that are electrically connected to the LED, and the LED and other electrical components and electronic components are damaged. there were.

In the electronic device comprising the closed electronic component and a closing member that closes the opening, the closing member forms a bottomed cylindrical body, the opening faces the electronic component side, and the opening of the bottomed cylindrical body The shortest distance from the peripheral opening side peripheral edge of the bottomed cylindrical body to the conductor wiring is determined from the peripheral opening side peripheral edge of the bottomed cylindrical body. It was made shorter than the shortest distance to the parts.

この発明は、筐体の開口部を塞ぐ閉塞部材を有底筒状体とし、該有底筒状体の外周開口側周縁から筐体内の回路基板上に形成されたグランド用の導体配線までの最短距離を、前記有底筒状体の外周開口側周縁から前記開口部に対峙する回路基板上に実装された電子部品までの最短距離よりも短くしたことから、筐体と閉塞部材の間より流れ込んだ静電気をグランド用の導体配線に逃がし、静電気が前記電子部品に流れ込むことを確実に防止することができる。そのため、前記電子部品や回路基板上に実装される他の電子部品が破損することを防止できる。   According to the present invention, the closing member that closes the opening of the housing is a bottomed cylindrical body, and from the outer peripheral opening side periphery of the bottomed cylindrical body to the conductor wiring for ground formed on the circuit board in the housing Since the shortest distance is shorter than the shortest distance from the outer peripheral opening side periphery of the bottomed cylindrical body to the electronic component mounted on the circuit board facing the opening, between the casing and the closing member The flowing static electricity is released to the conductor wiring for the ground, and it is possible to reliably prevent the static electricity from flowing into the electronic component. Therefore, it is possible to prevent the electronic components and other electronic components mounted on the circuit board from being damaged.
以下、この発明の一実施形態を、図面を参照して説明する。この発明にかかる電子機器は、携帯電話機や簡易型携帯電話機、PDA等の携帯可能な種々の電子機器を含むものであるが、以下の実施形態はこの発明を携帯電話機に適用したものである。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The electronic device according to the present invention includes various portable electronic devices such as a mobile phone, a simple mobile phone, and a PDA. In the following embodiments, the present invention is applied to a mobile phone.
この実施形態の携帯電話機は、図1〜図5に示すように筐体1が縦長の略矩形状に形成されたストレートタイブと呼ばれる筐体構造を有する電話機であり、筐体1は、厚み方向でほぼ半割りとされたフロントケース2とリヤケース3が相互に結合された構造となっている。   The mobile phone of this embodiment is a phone having a case structure called a straight tie in which the case 1 is formed in a vertically long, substantially rectangular shape as shown in FIGS. 1 to 5, and the case 1 has a thickness direction. Thus, the front case 2 and the rear case 3 which are substantially divided in half are coupled to each other.
フロントケース2の前面には、その中央に数字の入力を行う数字キー4a、オフフックボタンとしての通話キー4b、オンフックボタンとしての終話キー4cから成る操作キー群が配置されると共に、上端部と下端部に受話部5と送話部6が配置され、さらに下端部の送話部6の近傍には電波状況とバッテリーの残状況を知らせるためのLEDによる発光インジケータ部7及び電源のオン、オフのためのスライドスイッチ18が配置されている。一方、リヤケース3の背面には、その略下半領域にバッテリー交換用の蓋8が開閉可能に設けられると共に、上端部の左側(フロントケース2の前面から向かって見た場合。)に偏奇した位置にアンテナ収容部9が外側に円弧状に膨出して形成されており、そのアンテナ収容部9にアンテナ15が収容されている。   On the front surface of the front case 2, an operation key group including a numeric key 4a for inputting numbers, a call key 4b as an off-hook button, and an end key 4c as an on-hook button is arranged at the center, A receiver 5 and a transmitter 6 are arranged at the lower end, and a light emitting indicator 7 with an LED for notifying the radio wave status and the remaining battery status and power on / off in the vicinity of the transmitter 6 at the lower end. A slide switch 18 is provided. On the other hand, on the rear surface of the rear case 3, a battery replacement lid 8 is provided in a substantially lower half region so as to be openable and closable, and the rear case 3 is biased toward the left side of the upper end (when viewed from the front of the front case 2). The antenna accommodating portion 9 is formed at a position so as to bulge outward in an arc shape, and the antenna 15 is accommodated in the antenna accommodating portion 9.
筐体1の内部には、図4,図5に示すようにフロントケース2とリヤケース3に挟み込まれるかたちで、複数の電気/電子部品を実装する回路基板10が取り付けられると共に、この回路基板10の下面側(リヤケース3側)の中央付近に略矩形状のバッテリー11が収納されている。また、筐体1内には、この回路基板10とバッテリー11の他、受話用スピーカと送話用マイクロフォン(いずれも図示せず)が収納されている。なお、受話用スピーカーは報知用スピーカとしても機能するようになっている。   As shown in FIGS. 4 and 5, a circuit board 10 on which a plurality of electrical / electronic components are mounted is mounted inside the housing 1 so as to be sandwiched between the front case 2 and the rear case 3. A substantially rectangular battery 11 is housed in the vicinity of the center of the lower surface side (rear case 3 side). In addition to the circuit board 10 and the battery 11, a speaker for reception and a microphone for transmission (both not shown) are housed in the housing 1. The receiving speaker functions also as a notification speaker.
ここで、前記発光インジケータ部7は、フロントケース2の下端前面に形成された略楕円状の2つの開口部12に夫々嵌入されたLEDカバー14(閉塞部材)と、回路基板10上の各LEDカバー14に対峙する位置に実装された2つのLED13(電子部品)とを備えている。   Here, the light emitting indicator portion 7 includes an LED cover 14 (blocking member) fitted in two substantially elliptical openings 12 formed on the front surface of the lower end of the front case 2, and each LED on the circuit board 10. Two LEDs 13 (electronic components) mounted at positions facing the cover 14 are provided.
LEDカバー14は、図6〜図9に示すように有底筒状に形成され、その封止端側が照射窓になっている。LEDカバー14は、より具体的には、封止端側が開口部12とほぼ合致する略楕円状の断面形状とされると共に、開口端側が封止端側よりも一回り大きい略D字状の断面形状に形成されている。以下、封止端側の略楕円状の断面部を先端部14aと呼び、開口端側の略D字状の断面部分を台座部14bと呼ぶものとする。   The LED cover 14 is formed in a bottomed cylindrical shape as shown in FIGS. 6 to 9, and the sealing end side is an irradiation window. More specifically, the LED cover 14 has a substantially elliptical cross-sectional shape in which the sealing end side substantially coincides with the opening 12, and the opening end side is substantially D-shaped that is slightly larger than the sealing end side. It is formed in a cross-sectional shape. Hereinafter, the substantially elliptical cross-sectional portion on the sealing end side is referred to as a tip portion 14a, and the substantially D-shaped cross-sectional portion on the opening end side is referred to as a pedestal portion 14b.
また、LEDカバー14は透光性を有するプラスチック、樹脂、セラミックス、単結晶体のいずれかの絶縁性材料により形成してある。   The LED cover 14 is made of an insulating material of any one of plastic, resin, ceramics, and single crystal having translucency.
LEDカバー14は、図7,図8に示すように2つ一組とされ、これらの各台座部14bが、黒色のゴム材から成る絶縁性の弾性ホルダー15に保持されている。この弾性ホルダー15は、全体がほぼ矩形の板状に形成され、その板状のベース部に、各LEDカバー14の先端部が挿入される貫通孔16を有すると共に、各貫通孔16の孔縁にLEDカバー14の台座部14bが嵌合される略D字状の窪み部17が形成されている。また、この窪み部17の周壁には、図10に示すように凹部17aが形成され、この凹部17aに台座部14b周縁のフランジ部18が嵌合されるようになっている。   As shown in FIGS. 7 and 8, the LED covers 14 are made into a set, and each of these pedestals 14b is held by an insulating elastic holder 15 made of a black rubber material. The elastic holder 15 is formed in a substantially rectangular plate shape as a whole, and has a through hole 16 into which the tip end portion of each LED cover 14 is inserted in the plate-like base portion, and a hole edge of each through hole 16. A substantially D-shaped recess portion 17 into which the base portion 14b of the LED cover 14 is fitted is formed. Further, as shown in FIG. 10, a concave portion 17a is formed on the peripheral wall of the hollow portion 17, and the flange portion 18 on the periphery of the pedestal portion 14b is fitted into the concave portion 17a.
ここで、窪み部17の高さは台座部14bの高さよりも高く設定されており、窪み部17に台座部14bを嵌合した状態において、図9,図10に示すように台座部14bの裏面が弾性ホルダー15の背面から一段窪むようになっている。したがって、弾性ホルダー15の背面が回路基板10に当接した状態においては、LEDカバー14の台座部14bと回路基板10が非接触状態に維持される。   Here, the height of the dent portion 17 is set higher than the height of the pedestal portion 14b. When the pedestal portion 14b is fitted to the dent portion 17, the pedestal portion 14b has a height as shown in FIGS. The back surface is recessed by one step from the back surface of the elastic holder 15. Therefore, in a state where the back surface of the elastic holder 15 is in contact with the circuit board 10, the base portion 14b of the LED cover 14 and the circuit board 10 are maintained in a non-contact state.
また、弾性ホルダー15の略中央には長孔状の係合孔19が形成され、フロントケース2の背面の開口部12に近接した位置には、弾性ホルダー15の係合孔19が嵌合される舌片状の係止突起20が形成されている。   In addition, an elongated engagement hole 19 is formed in the approximate center of the elastic holder 15, and the engagement hole 19 of the elastic holder 15 is fitted at a position close to the opening 12 on the back surface of the front case 2. A tongue-like locking projection 20 is formed.
2つのLEDカバー14は、図7,図8に示すように予め弾性ホルダー15に組み付けて組立体を形成し、その状態でLEDカバー14の先端部14aを開口部12に嵌合し、かつ、弾性ホルダー15の係合孔19にフロントケース2の係合突起20を嵌合することによって、図4,図9,図10に示すようにフロントケース2に固定される。   As shown in FIGS. 7 and 8, the two LED covers 14 are assembled in advance to the elastic holder 15 to form an assembly, and in this state, the front end portion 14a of the LED cover 14 is fitted into the opening 12, and By fitting the engaging protrusion 20 of the front case 2 into the engaging hole 19 of the elastic holder 15, the elastic holder 15 is fixed to the front case 2 as shown in FIGS. 4, 9 and 10.
一方、回路基板10の開口部12に対応する位置には、図9に示すようにランド部21が形成され、そのランド部21にLED13がはんだ結合されている。前述のようにフロントケース2に固定された各LEDカバー14は、フロントケース2を回路基板10に結合したときにLED13の前方を覆うこととなるが、このとき、弾性ホルダー15の窪み部17の周縁部が各LED13の周域に密接するようになる。ここで、弾性ホルダー15は黒色のゴム材によって形成されているため、このときLED13の周域からの光の漏れはこの弾性ホルダー15によって阻止される。   On the other hand, a land portion 21 is formed at a position corresponding to the opening 12 of the circuit board 10 as shown in FIG. 9, and the LED 13 is soldered to the land portion 21. As described above, each LED cover 14 fixed to the front case 2 covers the front of the LED 13 when the front case 2 is coupled to the circuit board 10. At this time, the LED cover 14 of the elastic holder 15 has a recess 17. The peripheral edge comes into close contact with the peripheral area of each LED 13. Here, since the elastic holder 15 is formed of a black rubber material, at this time, leakage of light from the peripheral area of the LED 13 is blocked by the elastic holder 15.
また、図9に示すように回路基板10のLED13の配置される側の面にはグランド用の導体配線22が設けられている。この導体配線22は、少なくとも各LEDカバー14の台座部14bの直下位置を横切るように設けられている。この状態において、LEDカバー14の外周開口側周縁から導体配線22までの最短距離d1はLEDカバー14の外周開口側周縁からLED13までの最短距離d2よりも短くなるように設定されている。
また、回路基板10上のLED13用のランド部21と導体配線22の間にはレジスト膜23が設けられ、LED13をランド部21にはんだ結合する際に、はんだクリームが導体配線22に流れ出すのをそのレジスト膜23によって阻止し得るようになっている。
Further, as shown in FIG. 9, a ground conductor wiring 22 is provided on the surface of the circuit board 10 on the side where the LEDs 13 are arranged. The conductor wiring 22 is provided so as to cross at least a position directly below the base portion 14b of each LED cover 14. In this state, the shortest distance d1 from the outer periphery opening side periphery of the LED cover 14 to the conductor wiring 22 is set to be shorter than the shortest distance d2 from the outer periphery opening side periphery of the LED cover 14 to the LED 13.
Further, a resist film 23 is provided between the land portion 21 for the LED 13 on the circuit board 10 and the conductor wiring 22, and the solder cream flows out to the conductor wiring 22 when the LED 13 is solder-bonded to the land portion 21. The resist film 23 can prevent this.
この携帯電話機は以上のような構成であるため、着信等によってLED13が点灯すると、そのLED13の発した光がLEDカバー14の照射窓を通して前方に照射される。このときLEDカバー14の内周は球面状に湾曲して形成されているため、LEDカバー14の内面に当たった光は多用な方向に拡散し、ムラのない均一な光が前方に照射される。また、この携帯電話機においては、LEDカバー14の台座部14bの周囲が、黒色ゴムから成る弾性ホルダー15によって囲繞され、LED13の周囲からの光の漏れが確実に防止されているため、照射窓からのみ光を照射することができる。   Since this mobile phone has the above-described configuration, when the LED 13 is lit by an incoming call or the like, the light emitted from the LED 13 is irradiated forward through the irradiation window of the LED cover 14. At this time, since the inner periphery of the LED cover 14 is curved in a spherical shape, the light hitting the inner surface of the LED cover 14 diffuses in various directions, and uniform light without unevenness is irradiated forward. . Further, in this cellular phone, the periphery of the base portion 14b of the LED cover 14 is surrounded by the elastic holder 15 made of black rubber, and light leakage from the periphery of the LED 13 is reliably prevented. Only light can be irradiated.
また、ユーザーが帯電した手で筐体1に触れ、静電気が筐体2とLEDカバー14の隙間に流れ込むと、静電気はLEDカバー14の外周面を流れ、台座部14bから回路基板10上のグランド用の導体配線22上に流れる。つまり、LEDカバー14の台座部14bからグランド用の導体配線22までの最短距離d1をLED13までの最短距離d2よりも短く設定してあるため、LEDカバー14の台座部14bに達した静電気はLED13側には流れず、グランド用の導体配線22側に確実に逃がすことができる。   Further, when the user touches the housing 1 with a charged hand and static electricity flows into the gap between the housing 2 and the LED cover 14, the static electricity flows through the outer peripheral surface of the LED cover 14, and the ground on the circuit board 10 from the pedestal portion 14b. It flows on the conductor wiring 22 for use. That is, since the shortest distance d1 from the pedestal portion 14b of the LED cover 14 to the ground conductor wiring 22 is set shorter than the shortest distance d2 to the LED 13, the static electricity reaching the pedestal portion 14b of the LED cover 14 is reduced to the LED13. It does not flow to the side and can be surely escaped to the ground conductor wiring 22 side.
また、この携帯電話機の場合、LEDカバー14が、回路基板10との間に隙間ができるように弾性ホルダー15に保持されているため、仮に,筐体1の外部からLEDカバー14に回路基板10方向の押圧力が作用しても、このとき回路基板10に作用する応力を弾性ホルダー15による緩衝機能によって大きく緩和することができる。したがって、回路基板10に局部的な応力が作用することによる実装部品の剥離を未然に防止することができる。   In the case of this cellular phone, the LED cover 14 is held by the elastic holder 15 so that a gap is formed between the LED board 14 and the circuit board 10. Even if the pressing force in the direction acts, the stress acting on the circuit board 10 at this time can be greatly relieved by the buffer function by the elastic holder 15. Therefore, it is possible to prevent the mounted component from being peeled off due to local stress acting on the circuit board 10.
以上、この発明の一実施形態について説明したが、筐体2の開口部12に対峙する回路基板10上に実装されるこの発明における電子部品は、発光ダイオード(LED)だけに限らず、光センサ等の静電気を嫌う他の電子部品にも適用できる。
