- Patent Document 1 discloses an FPC integrated gasket formed integrally with the FPC (30) and formed in a grommet shape.
- the FPC integrated gasket (1) is provided with a pair of gaskets (10) made of a rubber-like elastic body.
- a protrusion (50) that seals the through hole (3) of the housing (2) is provided at the tip of each gasket (10).
- the protrusion (50) has a tapered surface (53) inclined from the cross-sectional area surface (52) larger than the diameter of the through hole (3) of the housing (2) toward the tip surface (54).
- the pair of gaskets (10) can transmit and receive electrical signals between circuits in each casing (2) while waterproofing the two casings (2).
- the conventional FPC integrated gasket has the following problems.
- An object of the present invention is to provide a seal structure or the like in an electronic device or the like that can flexibly cope with a design change of a wiring member such as an FPC and can be formed at low cost.
- the seal structure of the present invention is a seal structure for sealing a through hole of a housing into which a wiring member is inserted.
- the seal structure includes a spacer member disposed on one side of the through hole, and includes a covering member that fixes and seals the spacer member, the wiring member, and the housing.
- the gap produced by the step corresponding to the thickness of the wiring member is filled with the covering by the seal structure of the present invention. This reliably prevents the entry of water or the like from the through hole.
- the covering body can be configured by providing an opening through which the wiring member is inserted in the spacer member and an adhesive layer that closes the opening while embedding a part of the wiring member.
- the wiring member extends from the through hole into the housing through the opening of the spacer member.
- the spacer member Since the spacer member is fixed to the region around the through hole of the housing, the inside of the housing can be reliably sealed.
- the spacer member only needs to have an opening through which the wiring member is inserted, and has a simple structure. Therefore, since the spacer member can be formed separately from the wiring member, the seal structure of the present invention can flexibly cope with a design change of the wiring member. Further, unlike Patent Document 1, it is not necessary to integrally mold with FPC or the like, so that the selection range of materials is expanded. Therefore, a waterproof structure can be realized at low cost by using a spacer member having a simple structure. If the spacer member is a thin ring or flat plate, a waterproof structure can be realized even in a narrow gap.
- the covering includes a cover member that faces the spacer member with a part of the wiring member interposed therebetween, and an adhesive layer that closes a gap between the spacer member and the cover member while embedding a part of the wiring member.
- This also provides a structure in which the wiring member and the spacer member are reliably sealed on one surface side of the spacer member. Therefore, a waterproof structure can be constructed at low cost by using a spacer member having a simpler structure without using a lid member.
- the covering body may be configured to include a fixing member disposed between a region surrounding the opening of the housing and the spacer member. By attaching the fixing member on the surface of the spacer member facing the housing in advance, the spacer member can be easily attached to the housing.
- a double-sided waterproof tape can be adopted as the fixing member.
- the adhesive layer can be made of a resin adhesive having repairability (peelability). Since the adhesive layer is made of a repairable resin adhesive, it is possible to reconnect the wiring members. Therefore, a highly practical seal structure can be obtained.
- thermosetting resin alone does not provide repairability and is not practical.
- thermoplastic resin alone has a low adhesive strength and is not reliable.
- the adhesive tape is used, the step due to the thickness of the wiring member is not filled.
- thermosetting resins such as epoxy resins, phenol resins, acrylic resins, urethane resins, alkyd resins, unsaturated polyester resins, polyvinyl alcohol resins, acrylic resins
- thermoplastic resins such as phenoxy resins and urethane resins
- the covering body preferably further includes a tape member that covers a region around the through hole of the housing.
- the stress applied to the covering can be relaxed by the tape member. Therefore, the reliability of the seal structure is improved.
- the method for forming the seal structure of the present invention can be performed by the following procedure. First, the wiring member is inserted through the through hole (step (a)). Next, in the region surrounding the through hole in a closed ring shape, the space between the spacer member, the wiring member, and the housing is filled with a fluid of a resin adhesive having a repair property (step (b)). Thereafter, the resin adhesive is solidified (step (c)).
- step (b) there is a method of pressing the spacer member from above after interposing the resin adhesive on at least a part of the surface where the spacer member contacts the wiring member or the casing.
- a semi-cured film-like resin adhesive is interposed between the wiring member and the housing and fluidized by a hot press.
- a resin adhesive that is a fluid is sandwiched between the wiring member and the housing and pressed from above the lid member.
- the space between the casing, the wiring member, and the spacer member is filled with the fluid of the resin adhesive. Therefore, a highly waterproof seal structure can be formed by a simple process.
- the covering portion includes a lid member facing the spacer member with a part of the wiring member interposed therebetween, and an adhesive layer that embeds a part of the wiring member and closes a gap between the spacer member and the lid member.
- the covering portion can be configured to include an adhesive layer that closes an opening of the spacer member while embedding a part of the wiring member.
- a fixing member constituting an adhesive layer can be provided in advance between the spacer member and the side opposite to the side where the adhesive layer is provided.
- a double-sided waterproof tape can be adopted as the fixing member. If this structure is employ
- the electronic device of the present invention has the above-described seal structure, and can form a waterproof structure for the electronic device at a low cost.
- a typical example is a mobile terminal.
- the wiring body is connected to the internal circuit of each casing through the through hole of each casing from the hinge portion or the slide portion.
- the seal structure seals the area around the through hole of each housing. In particular, when the present invention is applied to a slide-type portable terminal having a small space, significant effects can be exhibited.

Abstract
Description
特許文献1の図1~図3には、FPC(30)と一体でグロメット状に形成されたFPC一体化ガスケットが開示されている。FPC一体ガスケット(1)には、ゴム状弾性体からなる1対のガスケット(10)が設けられている。各ガスケット(10)の先端部には、筐体(2)の貫通孔(3)をシールする突起(50)が設けられている。突起(50)は、筐体(2)の貫通孔(3)の径よりも大きい断面積面(52)から先端面(54)に向かって傾斜するテーパ面(53)を有している。 Conventionally, an FPC-integrated gasket having a sealing structure for sealing a through hole provided in a casing of an electronic device such as a portable terminal is known.
1 to 3 of
第1に、突起(50)とFPC(30)を一体的に成形する金型などが必要である。そのため、FPCの設計変更のたびに新たな射出成形金型が必要になり、コストが高くなる。
第2に、FPC(30)と一体成形する必要があるため、ガスケット(10)を構成するゴム状弾性体の材料が限られる。
第3に、スライド式携帯端末のスライド部のように、電子機器内で2つの筐体間の狭い空間で、筐体と配線部材とをシールしなければならない場合がある。上記の構造では、ガスケット全体の高さ寸法が相当大きくなるので、このような小さな隙間に配置するのは困難である。 However, the conventional FPC integrated gasket has the following problems.
First, a mold for integrally molding the protrusion (50) and the FPC (30) is required. Therefore, a new injection mold is required every time the design of the FPC is changed, which increases the cost.
Second, since it is necessary to integrally mold with the FPC (30), the material of the rubber-like elastic body constituting the gasket (10) is limited.
Third, there may be a case where the housing and the wiring member need to be sealed in a narrow space between the two housings in the electronic device, such as a slide portion of a sliding portable terminal. In the above structure, since the height dimension of the entire gasket becomes considerably large, it is difficult to arrange in such a small gap.
図1は、本発明が適用される携帯端末(電子機器)の構造を概略的に示す斜視図である。
携帯端末1は、各種情報を表示するための表示部3と、入力部4と、スライド部8とを備えている。表示部3には、液晶表示パネルを用いた表示装置6やスピーカ等が設けられている。入力部4には、入力キーやマイクが設けられている。スライド部8は、表示部3側に設けられた外枠8aと、入力部4側に設けられた内枠8bとを、滑動自在に嵌合させて構成されている。 (Embodiment 1)

なお、本変形例2の接着剤層17の上に、図11に示すシールテープ19を貼り付けてもよい。これにより、蓋部材がないことによる信頼性の低下を防止することができる。 In the second modification, a waterproof structure can be realized without using a lid member. Since the lid member is unnecessary, a thinner seal structure than that of the third embodiment can be obtained.
In addition, you may affix the sealing
図14(a)は実施の形態3の変形例3に係るスペーサ部材の平面図、図14(b)は実施の形態3の変形例4に係るスペーサ部材の平面図である。
ハーネス部25a、25bが予め取り付けられたFPC21を用いてスペーサ部材11の開口に挿通する場合、図10(a)や図13(a)に示すスペーサ部材11では、その開口の周囲が閉じた状態であるため、前記開口の幅をハーネス部25a、25bの幅より広くする必要がある。
従って、ハーネス部25a、25bの幅がFPCの幅に比べてかなり大きい場合には、スペーサ部材11の開口幅もFPCの幅よりもかなり大きくする必要が生じる。従って、前記開口を接着剤で埋める必要が生じるため、あまり好ましいことではない。
そこで、図14(a)に示す実施の形態3の変形例3に係るスペーサ部材11では、その一箇所に開口から側方外部に通じた分断部11bを設けたものにしている。
これにより、ハーネス部25a、25bを予め取り付けたFPC21であっても、FPC21の部分をもって、側方から直接的に前記分断部11bを介して開口に入れることができる。
前記分断部11bは、その後の接着剤層17を形成する際に、結合して一体化状態とすることができる。よって、スペーサ部材11は、FPC21の幅に合わせて、その開口寸法を考慮すればよくなり、良好なシール構造を得ることができる。 -

前記一対のスペーサ片11c、11cは、その後の接着剤層17形成の際に、結合して一体化することができる。即ち、スペーサ部材11は、シール構造15として組み込まれた状態では、開口を備えて環状につながっている必要はあるが、組み込み前の状態では、必ずしも一体形状である必要はない。
よって、本変形例4においても、スペーサ片11c、11cからなるスペーサ部材11は、FPC21の幅に合わせてその開口寸法を考慮すればよくなり、良好なシール構造を得ることができる。 In the
