Description
【0001】[0001]
本考案は電子腕時計の静電シールド構造に関するものである。 The present invention relates to an electrostatic shield structure for an electronic wrist watch.
【0002】[0002]
最近の腕時計は、プラスチックの地板及び受で構成したムーブメントを、プラ スチックの外装に収納することにより、低価格やデザインの多様化に対応するも のが増えてきた。 ところで、プラスチックの地板や受で構成されたムーブメントでは、回路ブロ ックに載置されているICがプラスチック部品に囲まれた構造となっている。こ のため、これらのプラスチック部品に静電気が帯電しやすい。さらにプラスチッ クの外装を使用したものでは、地板や受ばかりでなく外装にも帯電する。 In recent wristwatches, the movement consisting of a plastic base plate and a bridge is housed in a plastic exterior, so that it is becoming more and more versatile to meet lower prices and diversify designs. By the way, in a movement composed of a plastic base plate and a bridge, the IC mounted on the circuit block is surrounded by plastic parts. Therefore, these plastic parts are easily charged with static electricity. Furthermore, in the case where a plastic exterior is used, not only the ground plane and the receiver but also the exterior are charged.
【0003】[0003]
しかしながら、プラスチック部品やプラスチックの外装に帯電した静電気の影 響で、ICが携帯中に誤動作してしまうという欠点を有している。マイコンIC を使用した、例えばクロノグラフやアラーム付の多機能時計では、この誤動作は 致命的である。 However, there is a drawback that the IC malfunctions while being carried by the influence of static electricity charged on the plastic parts and the exterior of the plastic. This malfunction is fatal in, for example, a chronograph or a multifunctional watch with an alarm using a microcomputer IC.
【0004】 本考案の目的は、上記課題を解決しようとするもので、従来の電子腕時計に対 し、耐静電気の向上を図る構造を提供するものである。An object of the present invention is to solve the above problems, and to provide a structure for improving the resistance to static electricity, as compared with a conventional electronic wrist watch.
【0005】[0005]
上記目的を達成するための本考案の要旨は、プラスチック製の地板と、該地板 の上面方向に配置される回路ブロックに載置されたICと、該ICの電源となる 電池より構成された電子腕時計のムーブメントに於いて、前記地板の下面方向に 配置される金属製の裏板と、該裏板と前記電池とを導通させる接続手段を設けた ことを特徴とするものである。 The gist of the present invention for achieving the above object is an electronic device including a plastic base plate, an IC mounted on a circuit block arranged in the upper surface direction of the base plate, and a battery serving as a power source of the IC. In a movement of a wristwatch, a metal back plate arranged in a lower surface direction of the main plate and a connecting means for electrically connecting the back plate and the battery are provided.
【0006】[0006]
本考案に於ける耐静電気構造は、文字板方向に電池と導通した裏板を設けた為 、プラスチック製の外装に帯電した静電気がICに影響させることが少なくなり 、また、地板を帯電させることも少なくなって、耐静電気を向上する構造になっ ている。 In the antistatic structure of the present invention, since the back plate which is electrically connected to the battery is provided in the dial direction, the static electricity charged on the plastic exterior is less likely to affect the IC, and the main plate is charged. It also has a structure that improves static resistance.
【0007】[0007]
以下図面により本考案の実施例を詳述する。図1は本考案の1つの実施例を示 す断面図である。回路ブロック1は、電池5で駆動されるIC1aを搭載するプ リント基板1bで構成されている。2は地板でありプラスチックで作られている 。3は回路ブロック1を地板2に固定させると共に、回路ブロック1の裏蓋9方 向の静電気シールドを果たす金属で作られている電池押エ板であり、一部に電池 5を押圧し、導通をとる押エ部3aを有している。4は地板2の文字板7方向の 静電気シールドを果たす金属製の裏板である。裏板4の一部に電池押エ板3とそ れを地板2に固定するネジを取り付ける支柱2aと圧接して導通をとるバネ部4 aを有している。文字板7は裏板4に載っている。プラスチックで作られた外装 の胴8、裏蓋9、風防ガラス10でムーブメントが囲まれている。6は裏蓋9を 固定するネジ、11はリューズである。バネ部4aは裏板4と一体でなくても良 く、別のバネ部品や、ネジで裏板4と電池押エ板3を導通させる方法もある。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing one embodiment of the present invention. The circuit block 1 is composed of a print substrate 1b on which an IC 1a driven by a battery 5 is mounted. Reference numeral 2 is a base plate, which is made of plastic. Reference numeral 3 denotes a battery pressing plate made of metal that serves to fix the circuit block 1 to the main plate 2 and also serves as an electrostatic shield in the direction of the back cover 9 of the circuit block 1. It has a pressing portion 3a for taking. Reference numeral 4 is a metal back plate which serves as an electrostatic shield in the direction of the dial 7 of the main plate 2. The back plate 4 is provided with a spring portion 4a which is brought into pressure contact with a battery pressing plate 3 and a pillar 2a to which a screw for fixing the battery pressing plate 3 to the base plate 2 is attached for electrical connection. The dial 7 is placed on the back plate 4. The movement is surrounded by a plastic outer casing 8, case back 9 and windshield 10. 6 is a screw for fixing the back cover 9, and 11 is a crown. The spring portion 4a does not have to be integrated with the back plate 4, and there is another spring component or a method of connecting the back plate 4 and the battery pressing plate 3 with a screw.
【0008】 IC1aは、裏板4の影にあってさらに電池押エ板3に挟まれた構造になって いるので、風防ガラス10や裏蓋9に帯電した静電気の影響を受け難くなってい る。Since the IC 1 a has a structure in which it is in the shadow of the back plate 4 and further sandwiched between the battery pressing plates 3, it is less susceptible to the static electricity charged on the windshield 10 and the back cover 9. .
【0009】[0009]
以上の説明で明らかなように、本考案によれば、プラスチック製の地板で構成 されたムーブメントを、上下面両方向より同電極性の金属部品で静電気シールド することにより、耐静電気が向上し、信頼性をますます高めた電子腕時計を提供 することができる。 As is clear from the above description, according to the present invention, the movement composed of the plastic base plate is electrostatically shielded by the metal parts having the same electrode property from both sides of the upper and lower surfaces, whereby the static electricity resistance is improved and the reliability is improved. It is possible to provide an electronic wrist watch with improved performance.
