Description

밀봉부재{SEALING MEMBER}Sealing member {SEALING MEMBER}

본 발명은, 전자기기의 밀봉부재에 관한 것으로서, 더욱 자세하게는, 휴대전화 단말 등의 전자기기의 내부에 액적(液滴)이 침입하지 않도록 시일하는 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing member of an electronic device, and more particularly, to a structure that seals a droplet so that it does not intrude into an electronic device such as a mobile phone terminal.

따라서, 본 발명의 밀봉부재는, 방수 전자기기의 시일 구조로서 적합하게 이용된다.Therefore, the sealing member of this invention is used suitably as a seal structure of waterproof electronic equipment.

도 6에 나타낸 바와 같이, 예컨대 휴대전화 단말에 있어서는, 서로 끼움결합 하는 하우징(100, 200)을 조합하여, 케이스가 형성되어 있으며, 이 케이스 내에 액적이 침입하지 않도록, 하우징(100, 200) 사이에는, 고무 단일체(單體)의 Ｏ링 등으로 이루어지는 개스킷(300)이 장착되어 있다(특허문헌 1).As shown in Fig. 6, for example, in a cellular phone terminal, a case is formed by combining housings 100 and 200 which are fitted to each other, and between the housings 100 and 200 so that droplets do not enter the case. The gasket 300 which consists of an O-ring etc. of a rubber unitary body is attached to this (patent document 1).

또한, 개스킷(300)은, 그 압축량(찌그러짐 여유, collapsing margin)을 일정하게 유지하기 위해, 하우징(200)에 설치한 환상(環狀) 홈(600) 내에 배치된다.Moreover, the gasket 300 is arrange | positioned in the annular groove 600 provided in the housing 200, in order to keep the compression amount (collapsing margin) constant.

이에 따라, 하우징(100, 200) 상호가 맞닿음으로써, 더 이상 과대하게 개스킷(300)이 압축되는 일은 없다.Accordingly, when the housings 100 and 200 abut each other, the gasket 300 is no longer excessively compressed.

그리고, 최근, 케이스의 소형화 및 슬림화가 요구되고 있기 때문에, 여기에 사용되는 개스킷(300)에 대해서도, 하우징(100,200)에 대하여 가능한 한 부하를 가하지 않도록, 소(小)단면화 및 저경도재(低硬度材)화가 요구되고 있다.In recent years, since miniaturization and slimming of the case are required, the small cross-section and the low hardness material are also applied to the gasket 300 used here so as not to put a load on the housings 100 and 200 as much as possible. Increasing levels of demand are required.

그렇지만, 이와 같이 개스킷(300)에 대하여 소단면화 및 저경도재화를 진행시키면, 개스킷(300) 자체의 강성(剛性)이 매우 작아질 수밖에 없다. However, when the small cross-section and the low hardness material are advanced to the gasket 300 in this way, the rigidity of the gasket 300 itself is inevitably reduced.

그 결과, 개스킷(300)의 핸들링성(취급 작업성)이 저하하기 때문에, 개스킷(300)의 조립작업의 작업 효율이 악화하는 문제를 초래했다.As a result, since the handling property (handling workability) of the gasket 300 falls, it caused the problem that the work efficiency of the assembly work of the gasket 300 deteriorates.

이 문제를 해결하기 위해서는, 도 7에 나타낸 바와 같이, 고무 단일체 개스킷(300)의 강성을 높여, 핸들링성(취급 작업성)을 향상시키는 시도가 이루어졌다.In order to solve this problem, as shown in FIG. 7, an attempt was made to increase the rigidity of the rubber monolithic gasket 300 and to improve handling (handling workability).

즉, 개스킷(300)에 수지 필름(500)을 전체 둘레에 걸쳐 일체화하는 것이 시도되었다. That is, it was attempted to integrate the resin film 500 in the gasket 300 over the whole perimeter.

이에 따라, 수지 필름(500)은, 고무 단일체의 개스킷(300)보다도 강성이 높기 때문에, 수지 필름(500)을 고무 단일체의 개스킷(300)에 일체화함으로써 개스킷(300)이 변형되기 어려워, 개스킷(300)의 핸들링성(취급 작업성)이 향상했다.Accordingly, since the resin film 500 is higher in rigidity than the gasket 300 of the rubber monolith, the gasket 300 is difficult to deform by integrating the resin film 500 into the gasket 300 of the rubber monolith. Handling property (handling workability) of 300) improved.

그러나, 이러한 개스킷(300)도, 도 6에 나타내는 바와 같은, 하우징(200)에 설치한 환상 홈(600) 내에 배치하여 사용할 필요가 있었다.However, such a gasket 300 also had to be disposed and used in the annular groove 600 provided in the housing 200 as shown in FIG. 6.

이 때문에, 하우징(200)에 환상 홈(600)을 형성하기 위한 비용이 높아질 뿐만 아니라, 하우징(200)의 두께가 두꺼워질 수밖에 없어, 케이스의 소형화 및 슬림화를 저해하는 요인의 하나로 되고 있었다.For this reason, the cost for forming the annular groove 600 in the housing 200 not only increases, but also the thickness of the housing 200 becomes thick, which is one of the factors that hinder the miniaturization and slimming of the case.

이러한 대책의 하나로서, 도 8에 나타낸 바와 같이, 고무 단체 개스킷(300)이 접착제층(700)을 사이에 두고, 하우징(100) 측에 고착되며, 평탄면의(홈을 설치하지 않은) 하우징(200)과의 사이에서 끼워 유지되는 양태가 제안되었다(특허문헌 2).As one such countermeasure, as shown in FIG. 8, the rubber single-piece gasket 300 is fixed to the housing 100 side with the adhesive layer 700 interposed therebetween, and has a flat surface (with no groove). The aspect which pinched | interrupts with (200) was proposed (patent document 2).

그러나, 하우징(100,200) 사이의 압축량(틈새)에 편차가 있기 때문에, 개스킷(300)의 안정된 시일 성능이 얻어지지 않는다는 문제를 야기했다.However, since there is a deviation in the amount of compression (gap) between the housings 100 and 200, it has caused a problem that stable sealing performance of the gasket 300 cannot be obtained.

The relief parts 4 of the lip parts 321a and 321b when the 32a and 32b are pressed and held between the two housing members 1 and 2 are provided.

이에 따라, 하우징 부재(1, 2)와 유지부재(31) 사이에서, 시일부재(32a, 32b)가 물려 들어가는 것에 의한 손상을 방지하는 동시에, 안정된 시일면압을 유지할 수 있다.As a result, damage between seal members 32a and 32b can be prevented between housing members 1 and 2 and holding member 31, and stable seal surface pressure can be maintained.

더욱이, 밀봉부재(3)는, 단면이 대략 H형상의 수지재로 만든 유지부재(31)를 사이에 두고, 하우징 부재(1, 2) 사이에, 확실히 안정된 상태로 끼워 유지되기 때문에, 밀봉부재(3)가 비틀려 장착될 위험성이 없다.Furthermore, since the sealing member 3 is held between the housing members 1 and 2 in a stable state with the holding member 31 made of a substantially H-shaped resin material in between, the sealing member is sealed. There is no danger of (3) being twisted and mounted.

또한, 이러한 종류의 밀봉부재(3)는, 방수 휴대전화에 적합하게 사용할 수 있으며, 이 경우, 일방의 하우징 부재(1)가 방수 휴대전화의 케이스이며, 타방의 하우징 부재(2)가 휴대전화 덮개가 된다.Moreover, this kind of sealing member 3 can be suitably used for a waterproof mobile phone, in which case one housing member 1 is a case of a waterproof mobile phone, and the other housing member 2 is a mobile phone. It becomes a cover.

게다가, 이러한 종류의 밀봉부재(3)는, 도 3에 나타내는 바와 같이, 양 하우징 부재(1, 2)의 평탄한 양면 사이에 끼워 유지되는 양태로 되어 있지만, 반드시 양 하우징 부재(1, 2)가 평탄할 필요는 없으며, 도 4에 나타낸 바와 같이, 타방의 하우징 부재(2)에 환상의 홈(6)을 설치하고, 이 홈(6) 내에 밀봉부재(3)를 배치하는 형태로 사용하는 것도 가능하다.Moreover, although this kind of sealing member 3 is shown to be sandwiched and held between the flat both surfaces of both housing members 1 and 2, as shown in FIG. It is not necessary to be flat, and as shown in FIG. 4, the annular groove 6 is provided in the other housing member 2, and it is also used in the form which arrange | positions the sealing member 3 in this groove 6. It is possible.

도 5는, 이러한 종류의 밀봉부재(3)가, 금형 내에 형성되어 있는 상태도이지만, 상부 금형(81) 및 하부 금형(82)에 각각 설치한 환상 돌기(811, 812, 821, 822)가 수지재로 만든 유지부재(31)에 맞닿아, 시일부재(32a, 32b)의 고무 재료가 버(burr)로서 유출되는 것을 저지하고 있기 때문에, 버의 발생을 억제할 수 있다.Although FIG. 5 is a state diagram in which this kind of sealing member 3 is formed in a metal mold | die, the annular protrusions 811, 812, 821, and 822 provided in the upper metal mold | die 81 and the lower metal mold | die 82 are resin, respectively. Since the rubber material of the sealing members 32a and 32b is prevented from coming out as a burr in contact with the holding member 31 made of ash, generation | occurrence | production of a burr can be suppressed.

특히, 유지부재(31)가 수지재로 만든 것이지만, 상부 금형(81) 및 하부 금형(82)과의 양호한 밀착접촉상태를 유지할 수 있기 때문에, 버의 발생을 억지할 수 있는 요인으로 되고 있다.In particular, although the holding member 31 is made of a resin material, it is possible to maintain good close contact with the upper mold 81 and the lower mold 82, which is a factor capable of inhibiting the occurrence of burrs.
