【考案の詳細な説明】
この考案は携帯時計で、特に電池ブタを使用する場合の
防水用電池ブタの構造に関するものである。[Detailed Description of the Invention] This invention relates to a waterproof battery cover structure for a portable watch, particularly when a battery cover is used.
従来の電池ブタを使用した電池ブタ部の防水構造は第1
図及び第3図に示すようにプレス成形したバヨネット爪
4を有する電池ブタを電池ブタバヨネット爪形状と緩嵌
する形状を有する裏ブタ3にパツキン2を介在して摺接
させ、バヨネット爪底面7を裏ブタ平面3aに摺動、取
着させることによって電池ブタ1を裏ブタ3に固定する
ものである。The waterproof structure of the battery cover using the conventional battery cover is the first.
As shown in FIGS. 3 and 3, a battery cover having a press-molded bayonet claw 4 is brought into sliding contact with a back cover 3 having a shape that fits loosely into the battery cover bayonet claw shape, with a packing 2 interposed therebetween, and a bayonet claw bottom surface 7 The battery cover 1 is fixed to the back cover 3 by sliding and attaching it to the back cover plane 3a.
しかしこのような構造ではバヨネット爪部の加工がプレ
ス成形が主体となる為に多種少量生産が不可能となり、
第2図に示す電池ブタ厚みLlを厚くする必要が生じて
ムーブメントとの干渉を防止する為の隙を設けることか
ら外装の総厚を厚くする等の欠点がある。However, with this structure, the processing of the bayonet claw part is mainly press molding, making it impossible to produce a wide variety of products in small quantities.
Since it is necessary to increase the battery cover thickness Ll shown in FIG. 2 and provide a gap to prevent interference with the movement, there are disadvantages such as increasing the total thickness of the exterior.
この考案は上記の欠点を除去するために、バヨネット爪
部の形状を切削加工が容易な形状にし、かつ電池ブタ厚
みを小さくして外装の総厚を薄くすることを目的とした
ものである。In order to eliminate the above-mentioned drawbacks, this invention aims to make the shape of the bayonet claw part easy to cut, and to reduce the thickness of the battery cover to reduce the total thickness of the exterior.
以下第4図、第5図、第6図により詳細に説明する。This will be explained in detail below with reference to FIGS. 4, 5, and 6.
第4図はこの考案の電池ブタの平面図であって、円形バ
ヨネット爪の外周部に2ケ所以上の対向する直線部を切
削加工により成形する。FIG. 4 is a plan view of the battery cover of this invention, in which two or more opposing linear portions are formed on the outer periphery of the circular bayonet claw by cutting.
裏ブタ乎面3aと摺動するパルネット爪4は第5図に示
す形状を有しており、バヨネット爪底面7は図のとおり
斜面状の形状を有している。The parnet claw 4 that slides on the back cover surface 3a has the shape shown in FIG. 5, and the bayonet claw bottom surface 7 has a sloped shape as shown in the figure.
以上の形状はすべて切削加工により成形する。All of the above shapes are formed by cutting.
第6図はこの考案の組立断面図であり、裏ブタ3にパツ
キンを介在して電池ブタ1を摺接させ、第5図のバヨネ
ット爪底面7を裏ブタ平面3aに摺動、取着させること
によって電池ブタ1を裏ブタ3に固定し、パツキンを圧
縮して防水を保持する。FIG. 6 is an assembled sectional view of this invention, in which the battery cover 1 is slid into contact with the back cover 3 through a gasket, and the bayonet claw bottom surface 7 of FIG. 5 is slid and attached to the back cover flat surface 3a. By doing this, the battery cover 1 is fixed to the back cover 3, and the gasket is compressed to maintain waterproofness.
以上述べたようにこの考案は斜面状のバヨネット爪底面

タ厚みL2を小さくでき、外装の総厚を薄くすることが
できる。As described above, in this invention, the battery cover thickness L2 can be reduced by attaching the sloped bayonet claw bottom surface and the sloped back cover plane, and the total thickness of the exterior can be reduced.
また電池ブタはすべて切削加工できることから多種少量
生産が可能となり、電池形状に応じた多種電池ブタ形状
の供給が容易となる。In addition, since all battery covers can be machined, it is possible to produce a wide variety of products in small quantities, making it easy to supply a wide variety of battery cover shapes according to battery shapes.
さらにパツキンは従来の上下に圧縮するパツキン本来の
正しい圧縮方式のため防水保持については従来通りの安
定性が得られる等の効果を有する。Furthermore, the packing has the effect of maintaining the same stability as before in terms of waterproofing because of the correct compression method originally used for packing, which compresses the packing vertically.
