Description

本発明は、電子機器、特に防水性能を有する携帯無線機等の端末機に実装された防水用キャップを有する携帯無線機に関するものである。   The present invention relates to a portable wireless device having a waterproof cap mounted on a terminal device such as a portable wireless device having waterproof performance, in particular, an electronic device.

電子機器、特に携帯電話等の携帯無線機の端末機では、他の電子機器との接続の為、或は端末機の調整を行う為のコネクタが実装されており、常時使用されないコネクタであることから該コネクタには防水用のキャップが装着され、該防水用キャップにより前記コネクタが保護される。   Electronic terminals, especially portable radio terminals such as mobile phones, are equipped with connectors for connecting to other electronic equipment or adjusting the terminal, and are not used at all times. Therefore, a waterproof cap is attached to the connector, and the connector is protected by the waterproof cap.

従来の携帯無線機の防水用キャップでは、ゴム材やエラストマ材、或はインサート成形や2色成形により成形された樹脂とエラストマの異種同時成形品が一般的に用いられているが、使用者がキャップの先端を引張った際にキャップが破断し、携帯無線機本体から脱落することが発生しており、キャップの着脱の際に求められる柔軟性と、着脱時に掛けられる大きな力に対向する引張り強度を兼ね備えた防水用キャップが求められている。   Conventional waterproof caps for portable radios generally use rubber materials, elastomer materials, or different types of resin and elastomer molded by insert molding or two-color molding. When the tip of the cap is pulled, the cap breaks and falls off the portable radio main unit. The flexibility required when attaching and detaching the cap and the tensile strength that opposes the large force applied when attaching and detaching the cap. There is a need for a waterproof cap that also has both.

然し乍ら、防水用キャップに求められる柔軟性と引張り強度の両立は困難であり、更に携帯無線機の小型化が進むにつれて、防水用キャップを携帯無線機本体に取付ける為のスペースが制限されることから、ゴム材、エラストマ材単体では所望の引張り強度を得ることが難しく、又異種同時成形品の場合もスペースの制限により合成樹脂とエラストマの接着面積が減少し、密着強度が低下することから、過度の引張り力が作用すると合成樹脂とエラストマが剥離する等所望の強度を得ることが難しいという問題があった。   However, it is difficult to achieve both the flexibility and tensile strength required for waterproof caps, and as the size of portable radios is further reduced, the space for attaching waterproof caps to portable radio units is limited. In addition, it is difficult to obtain the desired tensile strength with rubber materials and elastomer materials alone, and even in the case of different types of co-molded products, the adhesive area between the synthetic resin and the elastomer is reduced due to space limitations, so excessive adhesion There is a problem that it is difficult to obtain a desired strength, for example, the synthetic resin and the elastomer are peeled off when a tensile force is applied.

以下、図面を参照しつつ本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図1、図2に於いて、本発明に於ける防水用キャップ1及び該防水用キャップ1が取付けられる携帯無線機本体のシャーシ2について説明する。   1 and 2, a waterproof cap 1 and a chassis 2 of a portable radio main body to which the waterproof cap 1 is attached according to the present invention will be described.

先ず前記防水用キャップ1について説明する。該防水用キャップ1は異なる材質、例えば電気を通さず、水や薬品等により腐食され難く、強度や硬度が高い硬合成樹脂、例えばPC樹脂と、パッキン部、ヒンジ部、滑り止め部に最適な柔軟性と伸縮性に富む軟合成樹脂、例えばエラストマの異種材料とを一体成形したものであり、一体成形の方法としてはインサート成形、或は2色成形等の異種同時成形等がある。   First, the waterproof cap 1 will be described. The waterproof cap 1 is not suitable for different materials such as electricity, is hardly corroded by water or chemicals, and is ideal for hard synthetic resins such as PC resin, packing parts, hinge parts, and anti-slip parts. A soft synthetic resin rich in flexibility and stretchability, for example, a different material such as an elastomer, is integrally molded. As an integral molding method, there are insert molding, simultaneous molding such as two-color molding, and the like.

前記防水用キャップ1は、硬度と強度を要求される部位を形成するキャップ部10及びスライドリング部9と、柔軟性、伸縮性を要求される表層部20から構成され、前記キャップ部10及び前記スライドリング部9は所要の硬度と強度を有する合成樹脂(硬樹脂材)、例えばPC樹脂であり、前記表層部20は所要の柔軟性、伸縮性を有する合成樹脂(軟樹脂材)、例えばエラストマである。   The waterproof cap 1 is composed of a cap portion 10 and a slide ring portion 9 that form a portion that requires hardness and strength, and a surface layer portion 20 that requires flexibility and stretchability. The slide ring portion 9 is a synthetic resin (hard resin material) having required hardness and strength, for example, a PC resin, and the surface layer portion 20 is a synthetic resin (soft resin material) having required flexibility and stretchability, for example, an elastomer. It is.

前記表層部20は、前記キャップ部10の反シャーシ側の面(外面)に表層部として一体化され、更に前記キャップ部10より延出する部分の先端部はスライド部8となっており、該スライド部8には前記スライドリング部9が埋設され、前記キャップ部10と前記スライドリング部9とは、前記表層部20により連結されると共にキャップ部10と表層部20、スライドリング部9と表層部20とは一体化された構成となっている。   The surface layer portion 20 is integrated as a surface layer portion on the surface (outer surface) of the cap portion 10 on the side opposite to the chassis, and the tip portion of the portion extending from the cap portion 10 is a slide portion 8. The slide portion 8 has the slide ring portion 9 embedded therein, and the cap portion 10 and the slide ring portion 9 are connected by the surface layer portion 20 and the cap portion 10 and the surface layer portion 20, the slide ring portion 9 and the surface layer. The unit 20 has an integrated configuration.

前記キャップ部10は、後述するシャーシ2に形成された接触部であるキャップ嵌合凹部17に水密に嵌合し、該キャップ嵌合凹部17に密閉された所要の空間を形成する。前記キャップ部10の外面には、該キャップ部10の中心から偏心した位置に、円錐台形状のネジ座部3が突出形成され、該ネジ座部3の外周面には半円筒状の欠切部3aが形成されている。前記ネジ座部3には中心を貫通する貫通孔4が形成され、前記キャップ部10の内面側からは前記表層部20と同心に螺子ボス収納凹部15が凹設されている。   The cap portion 10 is watertightly fitted into a cap fitting recess 17 which is a contact portion formed in the chassis 2 described later, and forms a required space sealed in the cap fitting recess 17. On the outer surface of the cap portion 10, a frustum-shaped screw seat portion 3 is formed so as to protrude from the center of the cap portion 10. A semi-cylindrical notch is formed on the outer peripheral surface of the screw seat portion 3. Part 3a is formed. A through hole 4 penetrating the center is formed in the screw seat portion 3, and a screw boss receiving recess 15 is formed concentrically with the surface layer portion 20 from the inner surface side of the cap portion 10.

前記ネジ座部3の頂面を除く前記キャップ部10の外面には、前記表層部20が密着一体化され、該表層部20の前記ネジ座部3を囲繞する部分には前記欠切部3aを充足する凸部6が形成される。   The surface layer portion 20 is tightly integrated with the outer surface of the cap portion 10 excluding the top surface of the screw seat portion 3, and the notched portion 3 a is formed in a portion surrounding the screw seat portion 3 of the surface layer portion 20. Is formed.

又、図3に示される様に、前記表層部20は前記ネジ座部3とは反対側に延出してスライド部8を形成し、前記キャップ部10の端を超えた近傍で、直角に屈曲され、更に所定長延出した位置で前記シャーシ2側に近接する様にクランク状に屈曲した段差部7が形成される。該段差部7より先端側に、前記スライドリング部9が前記表層部20に埋設されている。   Further, as shown in FIG. 3, the surface layer portion 20 extends to the opposite side of the screw seat portion 3 to form a slide portion 8, and bends at right angles in the vicinity beyond the end of the cap portion 10. Further, a stepped portion 7 bent in a crank shape so as to be close to the chassis 2 side at a position extending a predetermined length is formed. The slide ring portion 9 is embedded in the surface layer portion 20 on the tip side of the stepped portion 7.

図4に示される様に、前記スライドリング部9は長円形状のリングであり、該スライドリング部9が形成する長孔11は、前記貫通孔4の中心線と平行な長径を有する長孔となっており、前記スライドリング部9の板厚は前記スライド部8の板厚と等しくなっている。   As shown in FIG. 4, the slide ring portion 9 is an oval ring, and the long hole 11 formed by the slide ring portion 9 is a long hole having a long diameter parallel to the center line of the through hole 4. Thus, the plate thickness of the slide ring portion 9 is equal to the plate thickness of the slide portion 8.

而して、前記キャップ部10と前記表層部20とが一体化した部分、前記スライドリング部9と前記表層部20とが一体化した部分は、硬樹脂材のキャップ部10とスライドリング部9によって変形せず、高強度であり、又前記表層部20のみの部分、即ち該表層部20の90°屈曲した部分、及び前記スライドリング部9に至る部分は軟樹脂材であるので、容易に屈曲し得、前記表層部20のみの部分はヒンジ部5を形成する。又、前記欠切部3aを充足すると共に一体化した前記凸部6は、前記ネジ座部3が前記表層部20に対して回転を抑止する回止めとなっている。   Thus, a portion where the cap portion 10 and the surface layer portion 20 are integrated, and a portion where the slide ring portion 9 and the surface layer portion 20 are integrated are a hard resin material cap portion 10 and the slide ring portion 9. The portion of the surface layer portion 20 alone, that is, the portion of the surface layer portion 20 bent by 90 ° and the portion reaching the slide ring portion 9 are made of a soft resin material. The portion of only the surface layer portion 20 that can be bent forms the hinge portion 5. In addition, the convex portion 6 that satisfies and integrates the notched portion 3 a is a rotation stop that prevents the screw seat portion 3 from rotating with respect to the surface layer portion 20.

前記キャップ部10の、前記表層部20より前記シャーシ2側に突出する部分はキャップ嵌合部12を形成する。該キャップ嵌合部12の下面には、後述する外部接続用基板21を収納可能なキャップ側基板収納凹部13が形成されると共に、前記キャップ嵌合部12の周面には全周に亘って連続する溝が刻設され、該溝には所要の柔軟性と弾力性を有する材質、例えばエラストマ製のパッキン16が嵌込まれ、該パッキン16は前記キャップ嵌合部12の周面より突出している。   A portion of the cap portion 10 that protrudes toward the chassis 2 from the surface layer portion 20 forms a cap fitting portion 12. On the lower surface of the cap fitting portion 12, a cap-side substrate storage recess 13 capable of storing an external connection substrate 21, which will be described later, is formed, and the peripheral surface of the cap fitting portion 12 extends over the entire circumference. A continuous groove is formed, and a material having required flexibility and elasticity, for example, an elastomer packing 16 is fitted into the groove, and the packing 16 protrudes from the peripheral surface of the cap fitting portion 12. Yes.

次に、前記防水用キャップ1が取付けられる前記シャーシ2の構造について説明する。該シャーシ2は、前記スライドリング部9及び前記キャップ部10と同材質の硬合成樹脂製であり、前記防水用キャップ1に対する取付け面(以下上面とする)には前記キャップ嵌合凹部17が形成され、該キャップ嵌合凹部17は、前記キャップ嵌合部12が嵌入可能であると共に、内寸が前記パッキン16の外寸よりも小さくなっている。   Next, the structure of the chassis 2 to which the waterproof cap 1 is attached will be described. The chassis 2 is made of a hard synthetic resin made of the same material as the slide ring portion 9 and the cap portion 10, and the cap fitting recess 17 is formed on a mounting surface (hereinafter referred to as an upper surface) with respect to the waterproof cap 1. The cap fitting recess 17 can be fitted with the cap fitting portion 12 and has an inner dimension smaller than an outer dimension of the packing 16.

前記キャップ嵌合凹部17には、前記キャップ嵌合部12が嵌合された状態で、前記ネジ座部3と同心となる様にネジボス部14が突出形成されている。該ネジボス部14の径は前記ネジボス部収納凹部15の径よりも小さく、前記ネジボス部14の高さは前記ネジボス部収納凹部15の深さより低くなっている。前記ネジボス部14には、該ネジボス部14が前記ネジボス部収納凹部15に収納された際に前記貫通孔4と同心となるネジ穴18が穿設されている。   A screw boss portion 14 is formed in the cap fitting recess 17 so as to be concentric with the screw seat portion 3 in a state where the cap fitting portion 12 is fitted. The diameter of the screw boss portion 14 is smaller than the diameter of the screw boss portion accommodating recess 15, and the height of the screw boss portion 14 is lower than the depth of the screw boss portion accommodating recess 15. The screw boss portion 14 is formed with a screw hole 18 that is concentric with the through hole 4 when the screw boss portion 14 is housed in the screw boss portion housing recess 15.

又、前記キャップ嵌合凹部17の底面には、前記ネジボス部14が形成された場所を避けてシャーシ側基板収納凹部19が形成される。該シャーシ側基板収納凹部19は、前記キャップ側基板収納凹部13との間に外部接続用基板21収納用の空間22を形成する(図5(B)参照)。前記シャーシ側基板収納凹部19にコネクタ等接続用部品が実装された前記外部接続用基板21が設けられ、該外部接続用基板21は、前記キャップ嵌合部12を外した状態で試験機等の外部装置と接続される様になっている。   In addition, a chassis-side board housing recess 19 is formed on the bottom surface of the cap fitting recess 17 so as to avoid a place where the screw boss 14 is formed. The chassis side substrate storage recess 19 forms a space 22 for storing the external connection substrate 21 between the cap side substrate storage recess 13 (see FIG. 5B). The chassis-side substrate storage recess 19 is provided with the external connection substrate 21 on which a connector or other connection component is mounted. The external connection substrate 21 is connected to a testing machine or the like with the cap fitting portion 12 removed. It is designed to be connected to an external device.

前記シャーシ2の前記キャップ嵌合凹部17と直交する面(側面)には、前記スライド部8が摺動可能な段差面24が形成されると共に該段差面24の略中央には抜止め凹部23が形成される。又側面には前記段差面24と対峙する様にスライド部抑え25が設けられ、前記段差面24の端部であり前記シャーシ2の角部には抜止め部31が設けられる。   A step surface 24 on which the slide portion 8 is slidable is formed on a surface (side surface) of the chassis 2 orthogonal to the cap fitting recess 17, and a retaining recess 23 is formed at the approximate center of the step surface 24. Is formed. A slide portion restraint 25 is provided on the side surface so as to face the step surface 24, and a retaining portion 31 is provided at an end portion of the step surface 24 and at a corner portion of the chassis 2.

前記スライド部抑え25は、該スライド部抑え25を前記シャーシ2に取付ける為の取付け部26と、前記段差面24と平行に延出するガイド部27と、該ガイド部27の先端から前記シャーシ2側に突設されたストッパ部28とを有する。該ストッパ部28の先端は前記抜止め凹部23に嵌合し、前記ストッパ部28を前記抜止め凹部23に嵌込んだ状態で、前記段差面24と前記ガイド部27との間には前記スライド部8が摺動可能な間隙29が形成される。   The slide part restraint 25 includes an attachment part 26 for attaching the slide part restraint 25 to the chassis 2, a guide part 27 extending in parallel with the stepped surface 24, and a front end of the guide part 27. And a stopper portion 28 projecting on the side. The tip of the stopper portion 28 is fitted in the retaining recess 23, and the slide portion 28 is inserted into the retaining recess 23 between the step surface 24 and the guide portion 27. A gap 29 in which the portion 8 can slide is formed.

前記スライド部8は、前記スライド部抑え25の先端を持ち上げた状態で、前記スライド部8を前記間隙29に挿入し、前記ストッパ部28が前記長孔11に嵌入された状態で前記スライド部抑え25を離すことで簡単に取付けられる。   The slide part 8 is inserted in the gap 29 with the tip of the slide part restraint 25 lifted, and the slide part restraint is inserted in the state where the stopper part 28 is fitted in the long hole 11. Can be easily attached by separating 25.

前記スライド部8は前記段差面24に沿って摺動され、又前記ストッパ部28と前記長孔11で摺動がガイドされると共に前記段差部7が前記抜止め部31に当接することで動きが規制され、前記ストッパ部28及び前記抜止め部31は前記スライド部8のストッパとなっている。   The slide portion 8 is slid along the stepped surface 24, and the sliding is guided by the stopper portion 28 and the long hole 11, and the stepped portion 7 moves by contacting the retaining portion 31. The stopper portion 28 and the retaining portion 31 serve as a stopper for the slide portion 8.

而して、前記防水用キャップ1は前記スライド部8の可動範囲で前記シャーシ2に対して近接離反可能となっている。   Thus, the waterproof cap 1 can be moved close to and away from the chassis 2 within the movable range of the slide portion 8.

次に、前記防水用キャップ1を前記シャーシ2に固定する際に用いられる取付けネジ32について説明する。   Next, the mounting screw 32 used when the waterproof cap 1 is fixed to the chassis 2 will be described.

該取付けネジ32は、該取付けネジ32を回転させるネジ頭部33と前記ネジ穴18に螺入される螺部34とを有し、前記ネジ頭部33は使用者が指で摘める程度の大きさを有すると共に、ドライバやコイン等で締結及び解除ができる様スリット溝35が刻設されている。   The mounting screw 32 includes a screw head 33 that rotates the mounting screw 32 and a screw portion 34 that is screwed into the screw hole 18. The screw head 33 can be gripped by a user with a finger. In addition to having a size, a slit groove 35 is engraved so that it can be fastened and released by a driver, a coin or the like.

前記螺部34と前記ネジ頭部33との間には細径(全周に亘っている)部36が形成され、該細径部36と前記ネジ頭部33の間にはシール溝が刻設され、該シール溝にはシール部材であるOリング38が嵌込まれ、該Oリング38の外寸は、前記貫通孔4の内寸よりも大きくなっている。   A small diameter (over the entire circumference) portion 36 is formed between the screw portion 34 and the screw head 33, and a seal groove is formed between the small diameter portion 36 and the screw head 33. The O-ring 38 which is a sealing member is fitted in the seal groove, and the outer dimension of the O-ring 38 is larger than the inner dimension of the through hole 4.

前記螺部34の先端より金属製のワッシャ37が螺入可能となっており、該ワッシャ37が前記螺部34を越えた細径部36では、軸心方向に自在に変位可能となっている。   A metal washer 37 can be screwed in from the tip of the screw portion 34, and the washer 37 can be freely displaced in the axial direction at a small diameter portion 36 beyond the screw portion 34. .

又、上記した前記取付けネジ32は蝶ボルト等前記スリット溝35を有さず、使用者が指で着脱できる様なものであってもよい。又、前記ネジボス部14に螺入される前記取付けネジ32の螺部34の長さは、前記スライド部8が摺動する前記間隙29の長さよりも短くなっている。   The mounting screw 32 described above does not have the slit groove 35 such as a butterfly bolt, and may be one that can be attached and detached by a user with a finger. Further, the length of the screw portion 34 of the mounting screw 32 screwed into the screw boss portion 14 is shorter than the length of the gap 29 in which the slide portion 8 slides.

又、図4に示される様に、スライド部8に埋設された前記スライドリング部9は、外周面の所要位置より突設する所要数の凸部39を有している。   As shown in FIG. 4, the slide ring portion 9 embedded in the slide portion 8 has a required number of convex portions 39 protruding from a required position on the outer peripheral surface.

該凸部39は、前記スライドリング部9の平面部に所定数形成された平面部凸部39aと、前記スライド部8の先端側の曲面部に形成された曲面部凸部39bと、前記段差部7側の曲面部に形成された曲面部凸部39cとを有しており、前記平面部凸部39a及び前記曲面部凸部39bは前記スライドリング部9の周面に対し垂直方向に突出し、前記曲面部凸部39cは前記段差部7の板厚中心と平行となる様、傾斜して突出している。   The convex portion 39 includes a predetermined number of flat surface convex portions 39 a formed on the flat surface portion of the slide ring portion 9, a curved surface convex portion 39 b formed on the curved surface portion on the distal end side of the slide portion 8, and the step difference. A curved surface convex portion 39c formed on the curved surface portion on the side of the portion 7, and the flat surface convex portion 39a and the curved surface convex portion 39b project in a direction perpendicular to the peripheral surface of the slide ring portion 9. The curved surface convex portion 39c protrudes in an inclined manner so as to be parallel to the thickness center of the stepped portion 7.

前記スライド部8(表層部20)は、前記スライドリング部9を包込み一体成形されるので、前記凸部39a〜39cは、前記スライド部8の内部に食込んだ状態となり、前記スライドリング部9と前記スライド部8との境界面に於いて剥離、ずれに対する抵抗力を発揮する様になっている。   Since the slide portion 8 (surface layer portion 20) encloses the slide ring portion 9 and is integrally formed, the convex portions 39a to 39c are in a state of being bitten into the slide portion 8, and the slide ring portion 9 and the slide portion 8 are designed to exhibit resistance to peeling and displacement.

図5を参照して、前記防水用キャップ1を前記シャーシ2に取付ける場合を説明する。尚、スライド部8は予め前記間隙29に挿入された状態とする。先ず前記取付けネジ32の前記螺部34を前記貫通孔4に挿通し、前記螺部34を挿通させた状態で該螺部34の先端から前記ワッシャ37を前記細径部36迄螺入させる。   The case where the waterproof cap 1 is attached to the chassis 2 will be described with reference to FIG. The slide portion 8 is inserted in the gap 29 in advance. First, the screw portion 34 of the mounting screw 32 is inserted into the through hole 4, and the washer 37 is screwed from the tip of the screw portion 34 to the small diameter portion 36 with the screw portion 34 inserted.

次に、前記ネジボス部14が前記ネジボス部収納凹部15に収納される様前記キャップ嵌合部12を前記キャップ嵌合凹部17に嵌合させ、前記貫通孔4に挿通された前記取付けネジ32を前記ネジ穴18に螺入させ、前記キャップ嵌合部12の内面が前記キャップ嵌合凹部17の底面に当接する迄、前記ネジ頭部33を締込む。   Next, the cap fitting portion 12 is fitted into the cap fitting concave portion 17 so that the screw boss portion 14 is accommodated in the screw boss portion accommodating concave portion 15, and the mounting screw 32 inserted through the through hole 4 is inserted. The screw head 33 is screwed into the screw hole 18 until the inner surface of the cap fitting portion 12 contacts the bottom surface of the cap fitting recess 17.

前記キャップ嵌合部12の前記キャップ嵌合凹部17への嵌合、及び前記取付けネジ32の締込みで、前記スライド部8も変位し、該スライド部8は前記段差面24に沿ってスライドする。   When the cap fitting portion 12 is fitted into the cap fitting recess 17 and the mounting screw 32 is tightened, the slide portion 8 is also displaced, and the slide portion 8 slides along the step surface 24. .

この時、前記パッキン16の外寸は、前記キャップ嵌合凹部17の内寸よりも大きいので、前記キャップ嵌合部12が嵌合される際に、前記キャップ嵌合凹部17の内壁によって前記パッキン16が圧縮され、弾性変形することで該パッキン16が前記キャップ嵌合凹部17の内壁と密着し、前記防水用キャップ1、前記シャーシ2間がシールされる。   At this time, since the outer dimension of the packing 16 is larger than the inner dimension of the cap fitting recess 17, the packing is caused by the inner wall of the cap fitting recess 17 when the cap fitting portion 12 is fitted. When the 16 is compressed and elastically deformed, the packing 16 comes into close contact with the inner wall of the cap fitting recess 17, and the waterproof cap 1 and the chassis 2 are sealed.

又、前記Oリング38の外寸は、前記貫通孔4の内寸よりも大きいので、前記取付けネジ32が挿通される際に、前記貫通孔4の内壁によって前記Oリング38が圧縮され、弾性変形することで該Oリング38が前記貫通孔4の内壁と密着し、前記防水用キャップ1、前記取付けネジ32間がシールされる。   Further, since the outer dimension of the O-ring 38 is larger than the inner dimension of the through-hole 4, the O-ring 38 is compressed by the inner wall of the through-hole 4 when the mounting screw 32 is inserted, and elastic. By deforming, the O-ring 38 comes into close contact with the inner wall of the through hole 4, and the space between the waterproof cap 1 and the mounting screw 32 is sealed.

前記パッキン16及び前記Oリング38の圧縮方向は、前記取付けネジ32の締付け方向とは直角の方向であるので、前記取付けネジ32の締付け力に拘らず、前記パッキン16及び前記Oリング38のシール力は一定しており、確実な水密性が得られる。   Since the compression direction of the packing 16 and the O-ring 38 is a direction perpendicular to the tightening direction of the mounting screw 32, the seal of the packing 16 and the O-ring 38 is irrespective of the tightening force of the mounting screw 32. Force is constant and reliable water tightness is obtained.

前記防水用キャップ1を前記シャーシ2から取外す際には、前記ネジ穴18に螺入された前記取付けネジ32を回転させ、該取付けネジ32を前記ネジ穴18から脱着させる。この時、前記取付けネジ32の変位に応じて前記ワッシャ37が前記細径部36を摺動し、該細径部36の端部に突当った前記ワッシャ37が前記ネジボス部収納凹部15の底面を押圧することで、前記キャップ嵌合部12が前記キャップ嵌合凹部17から嵌脱され、前記防水用キャップ1が前記シャーシ2から取外される。   When removing the waterproof cap 1 from the chassis 2, the attachment screw 32 screwed into the screw hole 18 is rotated, and the attachment screw 32 is detached from the screw hole 18. At this time, the washer 37 slides on the small-diameter portion 36 according to the displacement of the mounting screw 32, and the washer 37 hitting the end of the small-diameter portion 36 is the bottom surface of the screw boss portion housing recess 15. , The cap fitting portion 12 is fitted and detached from the cap fitting concave portion 17, and the waterproof cap 1 is removed from the chassis 2.

この時、前記ネジボス部14に螺入された前記螺部34の長さは前記スライド部8が摺動する前記間隙29の長さよりも短くなっているので、前記取付けネジ32脱着の際に、前記スライドリング部9が前記ストッパ部28に突当り、前記防水用キャップ1の取外しを妨げない様になっている。又、前記取付けネジ32が前記ネジ穴18から完全に取外された場合であっても、前記段差部7が前記抜止め部31と係合すると共に、前記ストッパ部28が前記スライドリング部9の内周面と接触し前記スライド部8の動きを規制するので、該スライド部8が前記ガイド部27から抜出し、前記防水用キャップ1が前記シャーシ2から外れない。更に、前記ストッパ部28の先端が前記抜止め凹部23に嵌込んでいるので、前記スライド部8が引張られ、前記スライドリング部9と当接した前記ストッパ部28に前記防水用キャップ1嵌脱側への力が加わった場合でも、前記ストッパ部28が前記抜止め凹部23の側面と突当ることで前記ストッパ部28が前記シャーシ2の側面から浮き上がり、前記防水用キャップ1が前記シャーシ2から外れることがない。   At this time, since the length of the screw portion 34 screwed into the screw boss portion 14 is shorter than the length of the gap 29 in which the slide portion 8 slides, The slide ring portion 9 abuts against the stopper portion 28 so as not to prevent the waterproof cap 1 from being removed. Even when the mounting screw 32 is completely removed from the screw hole 18, the stepped portion 7 is engaged with the retaining portion 31 and the stopper portion 28 is engaged with the slide ring portion 9. Since the movement of the slide portion 8 is restricted by contact with the inner peripheral surface of the slide portion 8, the slide portion 8 is pulled out from the guide portion 27, and the waterproof cap 1 is not detached from the chassis 2. Further, since the tip of the stopper portion 28 is fitted in the retaining recess 23, the slide portion 8 is pulled, and the waterproof cap 1 is inserted into and removed from the stopper portion 28 that is in contact with the slide ring portion 9. Even when a force is applied to the side, the stopper portion 28 comes into contact with the side surface of the retaining recess 23 to lift the stopper portion 28 from the side surface of the chassis 2, and the waterproof cap 1 is removed from the chassis 2. It will not come off.

上述の様に、本実施例の前記防水用キャップ1は軟樹脂材であるエラストマと硬樹脂材であるPC樹脂との異種同時成形品であり、柔軟性が必要な前記ヒンジ部5をエラストマ製とし、所要の硬度と強度が必要な前記キャップ部10と前記シャーシ2をPC樹脂製としたので、携帯無線機本体に落下や振動等の外的衝撃が加わった場合、或は使用者が前記防水用キャップ1を引張り前記ネジ座部3及びネジボス部14に応力が掛った場合でも前記防水用キャップ1が破損することがない。   As described above, the waterproof cap 1 according to the present embodiment is a heterogeneous co-molded product of an elastomer that is a soft resin material and a PC resin that is a hard resin material, and the hinge portion 5 that requires flexibility is made of an elastomer. Since the cap 10 and the chassis 2 that require the required hardness and strength are made of PC resin, when an external impact such as dropping or vibration is applied to the portable radio main unit, or the user Even when the waterproof cap 1 is pulled and stress is applied to the screw seat portion 3 and the screw boss portion 14, the waterproof cap 1 is not damaged.

又、前記スライド部8にPC樹脂製の前記スライドリング部9を埋設したことで、前記防水用キャップ1の取外し時に引張り応力が発生した場合でも前記スライドリング部9を介して前記スライド部8が引延され、該スライド部8に局部的に力が作用し、該スライド部8が破断することがない。   Further, since the slide ring portion 9 made of PC resin is embedded in the slide portion 8, the slide portion 8 can be interposed via the slide ring portion 9 even when a tensile stress is generated when the waterproof cap 1 is removed. It is stretched and a force is applied locally to the slide portion 8 so that the slide portion 8 is not broken.

又、前記スライドリング部9の外周面に前記凸部39を形成し、前記スライド部8との係合力を高め、エラストマの破断を防止し、更に前記凸部39を前記スライド部8に曲げ応力や引張り応力が加わった際に境界面の剥離に対する抵抗を持つ様な形状としたので、前記スライド部8に応力が加わった場合でも前記スライドリング部9と前記スライド部8との境界面に於ける剥離を抑制でき、密着強度をより高めることができる。   Further, the convex portion 39 is formed on the outer peripheral surface of the slide ring portion 9 to increase the engagement force with the slide portion 8 to prevent the elastomer from being broken. Further, the convex portion 39 is bent to the slide portion 8. In other words, even when a stress is applied to the slide portion 8, the boundary surface between the slide ring portion 9 and the slide portion 8 is formed. Peeling can be suppressed, and the adhesion strength can be further increased.

又、前記キャップ嵌合部12の外周面に全周に亘る溝を刻設し、該溝即ち前記防水用キャップ1の着脱方向に対して垂直にエラストマ製のパッキン16を嵌込んだので、前記防水用キャップ1を前記シャーシ2に取付ける際の前記取付けネジ32の締付け力に拘らず前記パッキン16の潰し代が一定であり、締付け力のばらつきが該パッキン16の潰し代に影響することはなく、安定した防水性能を実現することができる。   Further, a groove is formed on the outer peripheral surface of the cap fitting portion 12 over the entire circumference, and an elastomer packing 16 is fitted perpendicularly to the groove, that is, the attaching / detaching direction of the waterproof cap 1. Regardless of the tightening force of the mounting screw 32 when the waterproof cap 1 is attached to the chassis 2, the crushing allowance of the packing 16 is constant, and variations in the tightening force do not affect the crushing allowance of the packing 16. Stable waterproof performance can be realized.

又、前記防水用キャップ1と前記シャーシ2は前記取付けネジ32により固定されているので、携帯無線機本体に落下の振動や外的衝撃が加えられた場合でも、前記防水用キャップ1の前記シャーシ2からの浮き上がりや中心ずれが発生せず、防水性能の劣化を防止することができる。   Further, since the waterproof cap 1 and the chassis 2 are fixed by the mounting screws 32, the chassis of the waterproof cap 1 can be used even when a drop vibration or an external impact is applied to the portable radio device body. No lifting or center deviation from 2 occurs, and deterioration of waterproof performance can be prevented.

更に、前記取付けネジ32は前記細径部36を摺動する前記ワッシャ37を有し、該ワッシャ37が前記取付けネジ32の脱着と連動して前記防水用キャップ1を嵌脱方向へとスライドさせるので、該防水用キャップ1の取外しを行う際には前記取付けネジ32を緩めるだけでよく、作業性を向上させることができる。   Further, the mounting screw 32 has the washer 37 that slides on the small-diameter portion 36, and the washer 37 slides the waterproof cap 1 in the fitting / removing direction in conjunction with the mounting / demounting of the mounting screw 32. Therefore, when the waterproof cap 1 is removed, it is only necessary to loosen the mounting screw 32, and the workability can be improved.
