(57) [Summary] [Purpose] A waterproof structure for the housing that is easy to manufacture and highly waterproof. [Structure] A casing cover and a thermoplastic elastomer are two-color molded, and a convex portion of the thermoplastic elastomer serving as a waterproof packing is arranged on a joint surface between the casing cover and the main body of the casing.
Description
【０００１】[0001]
本考案は、携帯用通信機、音響機器等の筐体の防水構造に関するものである。 The present invention relates to a waterproof structure for housings of portable communication devices, audio equipment and the like.
【０００２】[0002]
従来の防水は、筐体の開口と同一形状の帯状の弾性パッキンを別途加工し、筐 体の開口部に装着するか、開口部の端面に液状ゴムを塗布して行っている。 Conventional waterproofing is performed by separately processing a band-shaped elastic packing having the same shape as the opening of the housing and mounting it on the opening of the housing, or by applying liquid rubber to the end surface of the opening.
【０００３】[0003]
従来の帯状パッキンを装着する方式は、自動化が難しく手間が掛かる。また液 状ゴムを塗布する方式は、筐体の開口部の形状に制約が多い。 The conventional method of attaching the band-shaped packing is difficult to automate and takes time. In addition, the method of applying liquid rubber has many restrictions on the shape of the opening of the housing.
【０００４】[0004]
本考案においては、筐体のカバーの全表面および筐体の本体との接合面に至る までを熱可塑性エラストマーと筐体を形成する熱硬化性樹脂とで二色成形した。 この際、筐体のカバーと本体との接合面における熱可塑性エラストマー端部が接 合面全周にわたり凸になるようにすると有利である。このようにパッキンを形成 することにより、筐体カバーと本体とを結合するだけで、両者の接合面において パッキンの凸部が圧縮され、シール性を完全にする。 In the present invention, the entire surface of the cover of the housing and the joint surface with the main body of the housing are two-color molded with the thermoplastic elastomer and the thermosetting resin forming the housing. At this time, it is advantageous that the end portion of the thermoplastic elastomer on the joint surface between the cover of the housing and the main body is convex over the entire circumference of the joint surface. By forming the packing in this way, only by joining the housing cover and the main body, the convex portion of the packing is compressed at the joint surface between the two, and the sealing property is perfected.
【０００５】[0005]
次に図面に示す一実施例に従って本考案を説明する。 The present invention will be described below with reference to an embodiment shown in the drawings.
【０００６】 熱硬化性樹脂と熱可塑性エラストマーとの二色成形により、熱硬化性樹脂から なる筐体のカバー１と熱可塑性エラストマーからなる防水パッキン２を作成して ある。そして筐体のカバー１と筐体の本体３との結合する接合面ａに位置する熱 可塑性エラストマーの防水パッキン２の端面を接合面全周にわたり帯状の凸部４ を形成してある。したがって、図２に示すように筐体のカバー１と筐体の本体３ とを結合した時に、凸部が圧縮されて接合面ａを完全にシールする。A two-color molding of a thermosetting resin and a thermoplastic elastomer is used to prepare a cover 1 of a casing made of a thermosetting resin and a waterproof packing 2 made of a thermoplastic elastomer. The end face of the waterproof packing 2 made of thermoplastic elastomer, which is located on the joint surface a where the cover 1 of the housing and the main body 3 of the housing are joined, is formed with a band-shaped convex portion 4 over the entire circumference of the joint surface. Therefore, when the cover 1 of the housing and the main body 3 of the housing are joined as shown in FIG. 2, the convex portion is compressed and the joint surface a is completely sealed.
【０００７】[0007]
本考案によれば、熱可塑性エラストマーを防水パッキンとして二色成形するの で、従来のようにパッキンを別途作成したり、あるいは液状パッキン材を塗布し たりする工程が省略でき、コスト低減につながるとともに、防水パッキンが筐体 カバーと筐体本体の接合面を凸部の圧縮変形によりシールするので、防水性が完 全となっている。 According to the present invention, since the thermoplastic elastomer is molded in two colors as the waterproof packing, it is possible to omit the step of separately preparing the packing or applying the liquid packing material, which leads to the cost reduction. Since the waterproof packing seals the joint surface between the case cover and the case body by compressive deformation of the convex part, the waterproof property is perfect.
