Description

本発明は、電子機器の密封部材に係り、更に詳しくは、携帯電話端末等の電子機器の内部へ水滴が浸入しないようにシールする構造に関するものである。
従って、本発明の密封部材は、防水電子機器のシール構造として好適に利用される。 The present invention relates to a sealing member of an electronic device, and more particularly to a structure that seals water droplets from entering an electronic device such as a mobile phone terminal.
Therefore, the sealing member of the present invention is suitably used as a sealing structure for waterproof electronic equipment.

図６に示す様に、例えば携帯電話端末においては、互いに嵌合するハウジング１００、２００を組み合わせて、ケースが形成されており、このケース内に水滴が浸入しないように、ハウジング１００、２００間には、ゴム単体のＯリング等よりなるガスケット３００が介装されている（特許文献１）。   As shown in FIG. 6, for example, in a mobile phone terminal, a housing is formed by combining housings 100 and 200 that are fitted to each other. Is provided with a gasket 300 made of a rubber O-ring (Patent Document 1).

また、ガスケット３００は、その圧縮量（潰し代）を一定に保つべく、ハウジング２００に設けた環状溝６００内に配置される。
このことにより、ハウジング１００、２００相互が当接することにより、それ以上過大にガスケット３００が圧縮される事は無い。
そして、近年、ケースの小型化及び薄肉化が要求されているため、ここに使用されるガスケット３００についても、ハウジング１００，２００に対してできるだけ負荷をかけないよう、小断面化および低硬度材化が要求されている。 Further, the gasket 300 is disposed in an annular groove 600 provided in the housing 200 in order to keep the compression amount (crushing allowance) constant.
As a result, the gaskets 300 are not excessively compressed when the housings 100 and 200 come into contact with each other.
In recent years, there has been a demand for downsizing and thinning of the case, so that the gasket 300 used here has a small cross section and a low hardness material so as not to apply a load to the housings 100 and 200 as much as possible. Is required.

しかしながら、このようにガスケット３００を小断面化及び低硬度材化を進めると、ガスケット３００自体の剛性が非常に小さく成らざるを得ない。
この結果、ガスケット３００のハンドリング性（取り扱い作業性）が低下することから、
ガスケット３００の組付作業の作業効率が悪化する問題を招来した。 However, if the gasket 300 is reduced in cross section and reduced in hardness as described above, the rigidity of the gasket 300 itself has to be very small.
As a result, the handling property (handling workability) of the gasket 300 decreases,
The problem that the working efficiency of the assembling work of the gasket 300 deteriorated was caused.

この問題を解決するには、図７に示すように、ゴム単体ガスケット３００の剛性を高めて、ハンドリング性（取り扱い作業性）を向上させる試みがなされた。
すなわち、ガスケット３００に樹脂フィルム５００を全周に亙って一体化することが試みられた。
このことにより、樹脂フィルム５００は、ゴム単体のガスケット３００よりも剛性が高いことから、樹脂フィルム５００をゴム単体のガスケット３００に一体化することによりガスケット３００が変形しにくくなり、ガスケット３００のハンドリング性（取り扱い作業性）が向上した。 In order to solve this problem, as shown in FIG. 7, an attempt was made to improve the handling property (handling workability) by increasing the rigidity of the single rubber gasket 300.
That is, it has been attempted to integrate the resin film 500 over the entire circumference with the gasket 300.
Accordingly, since the resin film 500 has higher rigidity than the gasket 300 made of a single rubber, by integrating the resin film 500 into the gasket 300 made of a single rubber, the gasket 300 is less likely to be deformed. (Handling workability) improved.

しかしながら、このようなガスケット３００も、図６に示す様な、ハウジング２００に設けた環状溝６００内に配置して使用する必要があった。
このため、ハウジング２００に環状溝６００を形成する為の費用が嵩むばかりでなく、ハウジング２００が肉厚にならざるを得ず、ケースの小型化及び薄肉化を阻害する要因の一つとなっていた。 However, such a gasket 300 also needs to be used by being disposed in an annular groove 600 provided in the housing 200 as shown in FIG.
For this reason, not only the cost for forming the annular groove 600 in the housing 200 is increased, but the housing 200 has to be thick, which is one of the factors that hinder the downsizing and thinning of the case. .

この対策の一つとして、図８に示す様に、ゴム単体ガスケット３００が接着剤層７００を介して、ハウジング１００側に固着され、平坦面の（溝を設けない）ハウジング２００との間で挟持する態様が提案された（特許文献２）。
しかし、ハウジング１００，２００間の圧縮量（間隙）がばらつく為、ガスケット３００の安定したシール性能が得られない問題を惹起した。 As one countermeasure against this, as shown in FIG. 8, a single rubber gasket 300 is fixed to the housing 100 side via an adhesive layer 700 and is sandwiched between a flat surface (no groove) housing 200. The mode to do was proposed (patent document 2).
However, since the amount of compression (gap) between the housings 100 and 200 varies, a problem that the stable sealing performance of the gasket 300 cannot be obtained is caused.

There is no danger.
Moreover, this kind of sealing member 3 can be suitably used for a waterproof cellular phone, in which case one housing member 1 is a waterproof cellular phone case, and the other housing member 2 is a cellular phone lid. Become.

更に、この種密封部材３は、図３に示す様に、両ハウジング部材１、２の平坦な両面間に挟持され態様としているが、必ずしも両ハウジング部材１、２が平坦である必要はなく、図４に示す様に、他方のハウジング部材２に環状の溝６を設け、この溝６内に密封部材３を配置する形で使用する事も可能である。   Further, as shown in FIG. 3, the seed sealing member 3 is sandwiched between both flat surfaces of the housing members 1 and 2, but the housing members 1 and 2 are not necessarily flat.

特に、保持部材３１が樹脂材製であることが、上金型８１及び下金型８２との良好な密接状態を維持できる為、バリの発生を抑止できる要因となっている。 FIG. 5 is a state diagram in which the seed sealing member 3 is molded in a mold, and annular protrusions 811, 812, 821, and 822 provided on the upper mold 81 and the lower mold 82 are resin materials. Since the rubber material of the seal members 32a and 32b is prevented from flowing out as burrs by coming into contact with the holding member 31, the generation of burrs can be suppressed.
In particular, the fact that the holding member 31 is made of a resin material can maintain a good close contact state with the upper mold 81 and the lower mold 82, which is a factor that can suppress the occurrence of burrs.
