Description

本発明は、外部接続コネクタを有する携帯電話機などの携帯端末装置に関し、特に、外部接続コネクタの補強構造の改良に関する。   The present invention relates to a mobile terminal device such as a mobile phone having an external connection connector, and more particularly to improvement of a reinforcement structure of an external connection connector.

近年、携帯電話機等の携帯端末装置では、薄型化の要求が高まっている。また、携帯端末装置には、小型で軽量の外部接続コネクタが実装される。外部接続コネクタは、機器の外部から、プラグの抜き差しが行われる。特に、小型な外部接続コネクタは、強度が弱く、コンタクト（ソケット端子）や周囲配線や周囲部品が緩み変形し、断線する虞がある。   In recent years, there is an increasing demand for thinning mobile terminal devices such as mobile phones. The portable terminal device is mounted with a small and lightweight external connection connector. The external connection connector is inserted and removed from the outside of the device. In particular, a small external connector has low strength, and contacts (socket terminals), surrounding wiring, and surrounding parts may be loosened and deformed, resulting in disconnection.

特許文献１には、外部接続コネクタとは別体の補強板金を用いて、電子機器の筐体に実装された外部接続コネクタを補強する外部接続コネクタの補強構造が記載されている。特許文献１記載の外部接続コネクタの補強構造は、外部接続コネクタを別体の補強板金で押さえ、電子機器の角部ネジにより筐体と共締めする。補強板金は端部を折り曲げ加工し、内側は突起加工したボスにより左右上下に当て部を設けた構造としている。   Patent Document 1 describes a reinforcement structure for an external connection connector that reinforces an external connection connector mounted on a casing of an electronic device using a reinforcing sheet metal separate from the external connection connector. In the reinforcing structure of the external connection connector described in Patent Document 1, the external connection connector is pressed by a separate reinforcing sheet metal and is fastened together with the casing by a corner screw of the electronic device. The reinforcing sheet metal has a structure in which end portions are bent and the inner side is provided with contact portions on the left, right, top and bottom by protruding bosses.

特開２００８−１９９２２９号公報JP 2008-199229 A

しかしながら、特許文献１記載の外部接続コネクタの補強構造は、補強板金が大きいばかりか、その形状及び構造が複雑で、さらに上記補強板金の筐体への取付け方法も記載されていない。   However, the reinforcing structure of the external connection connector described in Patent Document 1 is not only a large reinforcing sheet metal, but also has a complicated shape and structure, and further does not describe how to attach the reinforcing sheet metal to the housing.

このため、外部接続コネクタの補強のためだけに、小型・薄型化が求められる携帯端末装置に、上記補強板金を実装することは考え難い。具体的には、長大な上記補強板金を、筐体に取り付けるためのネジ止め／ネジ受けなど新たな構造の付加によるコストアップ、上記補強板金が筐体内を専有することによる設置スペースの確保、長大な上記補強板金が設置されることによるアンテナ感度の低下やノイズ増大の課題がある。   For this reason, it is difficult to think of mounting the reinforcing sheet metal on a portable terminal device that is required to be small and thin only for reinforcing the external connection connector. Specifically, the cost is increased by adding a new structure such as screwing / screw receiving for attaching the long reinforcing sheet metal to the casing, securing the installation space by occupying the interior of the reinforcing sheet metal, and long There is a problem that antenna sensitivity is lowered and noise is increased due to the installation of the reinforcing sheet metal.

以上に加えて、特許文献１記載の外部接続コネクタの補強構造は、プラグの抜き差しについては記載されているものの、外部接続コネクタにプラグを挿した状態で、プラグを上下左右に少し振る、いわゆる抉り（コジリ）については記載がない。コジリ強度を強化するには、上記補強板金を精度良く加工する必要がある。特許文献１記載の外部接続コネクタの補強構造は、コジリに強い構造にはなっていない。上記補強板金の加工に困難性があることも、コジリ強化を妨げている。   In addition to the above, although the reinforcement structure of the external connection connector described in Patent Document 1 describes the insertion and removal of the plug, the plug is slightly swung up and down and left and right with the plug inserted into the external connection connector. (Kojiri) is not described. In order to enhance the strength, it is necessary to process the reinforcing sheet metal with high accuracy. The reinforcing structure of the external connection connector described in Patent Document 1 is not a structure that is strong against twisting. The difficulty in processing the reinforcing sheet metal also hinders strengthening.

なお、以下の説明において、外部接続コネクタにプラグを挿した状態で、プラグを上下左右などプラグ抜差しと違う方向に力を加え、その結果、プラグがプラグ抜差しと違う方向に動く状態を、コジリと呼ぶことにする。また、コジリ強度とは、プラグ抜差しと違う方向に力を加えても、コジリが生じない限界強さをいうものとする。   In the following explanation, with the plug inserted into the external connector, force is applied in the direction different from the plug insertion / removal, such as up / down / left / right. I will call it. In addition, the squeeze strength refers to a limit strength at which scouring does not occur even if a force is applied in a direction different from the plug insertion / removal.

本発明の目的は、補強板金の形状を、小型化・単純化すると共に加工の簡略化を図ることができ、コジリ強度を高めることができる携帯端末装置を提供することである。   An object of the present invention is to provide a portable terminal device capable of reducing the size and simplification of the shape of a reinforcing sheet metal and simplifying the processing, and increasing the squeezing strength.

本発明の携帯端末装置は、筐体と、前記筐体に収容される基板と、外形が略直方体で、一つの面に外部端子を差込み可能な差込口を有し、前記差込口が設けられた面と直交する一つの面である底面が、前記基板に固定された外部接続コネクタと、前記外部接続コネクタの前記底面以外の周囲を囲んで補強する補強板金と、を備える構成を採る。   The portable terminal device of the present invention has a housing, a substrate accommodated in the housing, a substantially rectangular parallelepiped shape, and an insertion port into which an external terminal can be inserted on one surface. A bottom surface, which is one surface orthogonal to the provided surface, has an external connection connector fixed to the substrate and a reinforcing sheet metal that surrounds and reinforces the periphery of the external connection connector other than the bottom surface. .

本発明によれば、外部接続コネクタを補強する補強板金の形状を、小型化・単純化すると共に加工の簡略化を図ることができ、コジリ強度を高めることができる。   According to the present invention, the shape of the reinforcing sheet metal that reinforces the external connection connector can be reduced in size and simplified, the processing can be simplified, and the galling strength can be increased.

（実施の形態）
図１は、本発明の一実施の形態に係る携帯端末装置の筐体の分解斜視図である。 (Embodiment)
FIG. 1 is an exploded perspective view of a housing of a mobile terminal device according to an embodiment of the present invention.

以下、本発明に係る携帯端末装置を、ＰＤＡ（Personal Digital Assistants）等の携帯情報端末で具現化する。また、カメラ付き携帯電話機／ＰＨＳ（Personal Handy-Phone System）の携帯通信端末に適用してもよい。   Hereinafter, the portable terminal device according to the present invention is embodied by a portable information terminal such as a PDA (Personal Digital Assistants). Further, the present invention may be applied to a camera-equipped mobile phone / PHS (Personal Handy-Phone System) mobile communication terminal.

図１に示すように、携帯端末装置１００は、バータイプの筐体１１０を備える。なお、携帯端末装置１００が、折畳式携帯電話機の場合、筐体１１０は、本体側筐体である。   As shown in FIG. 1, the mobile terminal device 100 includes a bar-type housing 110. When the mobile terminal device 100 is a foldable mobile phone, the housing 110 is a main body housing.

筐体１１０は、ケース１２０（第１筐体）と、ケース１２０に組み込まれる基板１３０と、基板１３０に底面１４０ｂ側が取り付けられた外部接続コネクタ１４０と、外部接続コネクタ１４０の周囲を底面１４０ｂ以外の三方面から囲んで補強する補強板金１５０と、ケース１２０に装着されるカバー１６０（第２筐体）と、を備える。   The housing 110 includes a case 120 (first housing), a substrate 130 incorporated in the case 120, an external connection connector 140 attached to the substrate 130 on the bottom surface 140b side, and the periphery of the external connection connector 140 other than the bottom surface 140b. A reinforcing sheet metal 150 that surrounds and reinforces from three sides and a cover 160 (second housing) attached to the case 120 are provided.

上記ケース１２０、基板１３０、補強板金１５０、及びカバー１６０は、ネジ１０１により共締めされる。   The case 120, the substrate 130, the reinforcing sheet metal 150, and the cover 160 are fastened together with screws 101.

ケース１２０は、例えばＡＢＳ樹脂等の合成樹脂フレームと金属板から構成され、図示しない表示パネル、スピーカ、マイクロホン、カメラ等が搭載される。   The case 120 is made of, for example, a synthetic resin frame such as ABS resin and a metal plate, and is mounted with a display panel, a speaker, a microphone, a camera, and the like (not shown).

基板１３０は、外部接続コネクタ１４０、及びmicroＳＤカードスロット１３１等の部品が実装されている。   The substrate 130 is mounted with components such as an external connection connector 140 and a microSD card slot 131.

外部接続コネクタ１４０は、差込口１４０ａと、差込口１４０ａの外周を囲う、底面１４０ｂと、底面１４０ｂに向かい合う表面１４０ｃと、底面１４０ｂと表面１４０ｃ間の側面１４０ｄ，１４０ｅと、を有する。底面１４０ｂは、基板１３０上に直付け固定されている。底面１４０ｂと表面１４０ｃは、平坦部となっている。   The external connector 140 has an insertion port 140a, a bottom surface 140b surrounding the outer periphery of the insertion port 140a, a surface 140c facing the bottom surface 140b, and side surfaces 140d and 140e between the bottom surface 140b and the surface 140c. The bottom surface 140b is directly fixed on the substrate 130. The bottom surface 140b and the surface 140c are flat portions.

外部接続コネクタ１４０は、例えばMicroＵＳＢである。MicroＵＳＢは、ＰＣ及びその周辺機器だけでなく、携帯電話機やモバイルデバイスとのデータ送受信用に使用される。MicroＵＳＢは、MiniＵＳＢと比較して外形寸法が約半分となっている。小型化により抜き差しに対応する耐久性と外部からの加重に耐える構造であることが必要である。本実施の形態のように、外部接続コネクタ１４０が、MicroＵＳＢである場合、特にコジリ強度を確保する必要がある。なお、外部接続コネクタ１４０は、MicroＵＳＢに限定されるものではなく、MiniＵＳＢ、各種ＵＳＢ変換コネクタ、Micro HDMIコネクタなどが使用される。   The external connection connector 140 is, for example, a MicroUSB. MicroUSB is used for data transmission / reception with not only PCs and peripheral devices but also cellular phones and mobile devices. MicroUSB has about half the external dimensions compared to MiniUSB. It is necessary to have a structure that can withstand durability and resistance from external loads due to downsizing. In the case where the external connection connector 140 is a MicroUSB as in the present embodiment, it is particularly necessary to ensure the twist strength. The external connection connector 140 is not limited to MicroUSB, and MiniUSB, various USB conversion connectors, a Micro HDMI connector, and the like are used.

図２は、補強板金１５０の構成を示す斜視図である。図２（ａ）は、基板１３０への取付け方向を上面と見た場合の斜視図、図２（ｂ）は、その下面から見た場合の斜視図である。   FIG. 2 is a perspective view showing the configuration of the reinforcing sheet metal 150. 2A is a perspective view when the mounting direction to the substrate 130 is viewed from the top surface, and FIG. 2B is a perspective view when viewed from the bottom surface.

図２に示すように、補強板金１５０は、外部接続コネクタ１４０の、基板１３０への直付け底面１４０ｂ以外の三方面（表面１４０ｃ及び側面１４０ｄ，１４０ｅ）を外形近似して折り曲げた折曲部１５０ａ−１５０ｄと、折曲部１５０ｂと折曲部１５０ｃとの間の平坦部１５０ｅと、を有する。   As shown in FIG. 2, the reinforcing sheet metal 150 includes a bent portion 150 a obtained by bending the external connection connector 140 by approximating the outer shape of the three sides (surface 140 c and side surfaces 140 d and 140 e) other than the bottom surface 140 b directly attached to the substrate 130. -150d and a flat portion 150e between the bent portion 150b and the bent portion 150c.

補強板金１５０は、平坦部１５０ｅから折曲部１５０ａ−１５０ｄに直交する方向の外方に延びたストッパ部１５０ｆと、ストッパ部１５０ｆから前記折り曲げ方向に突出した引掛かり部１５０ｇと、を有する。   The reinforcing sheet metal 150 includes a stopper portion 150f extending outward from the flat portion 150e in a direction perpendicular to the bent portions 150a to 150d, and a hook portion 150g protruding from the stopper portion 150f in the bending direction.

引掛かり部１５０ｇは、ケース１２０に形成された補強板金引掛け部１２２（図４参照）に挿入され、引掛かり部１５０ｇを係止させる。ストッパ部１５０ｆは、引掛かり部１５０ｇの係止後、ケース１２０に形成された補強板金脱落防止リブ１２３（図４参照）に当接して、ストッパ部１５０ｆの脱落を防止する。   The hook portion 150g is inserted into a reinforcing sheet metal hook portion 122 (see FIG. 4) formed in the case 120, and locks the hook portion 150g. The stopper part 150f contacts the reinforcing sheet metal drop-off prevention rib 123 (see FIG. 4) formed on the case 120 after the hook part 150g is locked, thereby preventing the stopper part 150f from dropping off.

補強板金１５０は、基板１３０にネジ止めするためのネジ穴１５０ｈ，１５０ｉを両端に有する。補強板金１５０は、外部接続コネクタ１４０が固定された基板１３０に、外部接続コネクタ１４０を覆って、ケース１２０と共にネジ１０１で共締めされる。なお、補強板金１５０は、外部接続コネクタ１４０の外周面突起に合わせた切欠部１５０ｊを有する。   The reinforcing sheet metal 150 has screw holes 150 h and 150 i at both ends for screwing to the substrate 130. The reinforcing sheet metal 150 covers the external connection connector 140 on the substrate 130 to which the external connection connector 140 is fixed, and is fastened together with the case 120 with the screw 101. The reinforcing sheet metal 150 has a notch 150j that matches the protrusion on the outer peripheral surface of the external connector 140.

このように、補強板金１５０は、外部接続コネクタ１４０の底面１４０ｂ以外の三方面（表面１４０ｃ及び側面１４０ｄ，１４０ｅ）を外形近似して、折曲部１５０ａ−１５０ｄにより折り曲げた構成となっている。図２から分かるように、補強板金１５０は、形状が従来例と比べ非常に単純化されている。形状が単純化されているので、加工工程も単純化されることになる。また、このような単純化された補強板金１５０は、単板を、打ち抜き・曲げ加工するだけで作成することができる。本実施の形態では、補強板金１５０の折り曲げ回数が少ないことから、加工の簡略化を図ることができる。   As described above, the reinforcing sheet metal 150 is configured by approximating the outer shape of the three sides (the surface 140c and the side surfaces 140d and 140e) other than the bottom surface 140b of the external connection connector 140 and bending them by the bent portions 150a to 150d. As can be seen from FIG. 2, the shape of the reinforcing sheet metal 150 is greatly simplified as compared with the conventional example. Since the shape is simplified, the machining process is also simplified. Further, such a simplified reinforcing sheet metal 150 can be produced by simply punching and bending a single plate. In the present embodiment, since the number of times the reinforcing sheet metal 150 is bent is small, the processing can be simplified.

また、補強板金１５０は、外部接続コネクタ１４０の必要強度に合わせて厚さを選定することも可能である。補強板金１５０の厚さの選定は、補強板金１５０の形状、及び加工の容易性に依存する。本実施の形態では、補強板金１５０は、形状が単純化されているので、必要強度に合わせた厚さの選定することができ、適用範囲を広げることができる。   Further, the thickness of the reinforcing sheet metal 150 can be selected according to the required strength of the external connection connector 140. The selection of the thickness of the reinforcing sheet metal 150 depends on the shape of the reinforcing sheet metal 150 and the ease of processing. In the present embodiment, since the shape of the reinforcing sheet metal 150 is simplified, the thickness according to the required strength can be selected, and the applicable range can be expanded.

図３は、補強板金１５０の外部接続コネクタ１４０への取付けを示す斜視図である。図３（ａ）は、その取付け後の斜視図、図３（ｂ）は、その基板１３０への取付け方向を上面と見た場合の斜視図、図３（ｃ）は、その下面から見た場合の斜視図である。   FIG. 3 is a perspective view showing attachment of the reinforcing sheet metal 150 to the external connection connector 140. 3 (a) is a perspective view after the mounting, FIG. 3 (b) is a perspective view when the mounting direction to the substrate 130 is viewed from the top, and FIG. 3 (c) is viewed from the bottom. FIG.

図３（ｂ）（ｃ）に示すように、外部接続コネクタ１４０を、補強板金１５０と基板１３０とで挟み込み、図３（ａ）に示すように、補強板金１５０を基板１３０に固定する。補強板金１５０と基板１３０とは、図１に示すように、ネジ１０１によるケース１２０、補強板金１５０、基板１３０、及びカバー１６０を共締めして固定される。共締めに筐体（ケース１２０及びカバー１６０）を含むことにより、筐体１１０の強度を取り込んだ強度向上を図ることができる。   As shown in FIGS. 3B and 3C, the external connector 140 is sandwiched between the reinforcing sheet metal 150 and the substrate 130, and the reinforcing sheet metal 150 is fixed to the substrate 130 as shown in FIG. As shown in FIG. 1, the reinforcing sheet metal 150 and the substrate 130 are fixed by tightening together the case 120, the reinforcing sheet metal 150, the substrate 130, and the cover 160 using the screws 101. By including the casing (the case 120 and the cover 160) in the joint fastening, the strength can be improved by incorporating the strength of the casing 110.

また、図３（ａ）に示すように、補強板金１５０は、外部接続コネクタ１４０の両脇直近にネジ穴１５０ｈ，１５０ｉが形成されている。補強板金１５０は、外部接続コネクタ１４０の直近にネジ穴１５０ｈ，１５０ｉを形成しているので、小型化を図ることができる。携帯電話等の電波を有する電子機器において、補強板金１５０の小型化は、アンテナ感度や、ノイズへの影響を小さくする効果がある。さらに、補強板金１５０は、外部接続コネクタ１４０の直近にネジ穴１５０ｈ，１５０ｉを形成しているので、コジリの際の補強板金１５０のたわみ変形量を少なくすることができ、強度アップを図ることができる。   As shown in FIG. 3A, the reinforcing sheet metal 150 has screw holes 150 h and 150 i formed in the immediate vicinity of both sides of the external connection connector 140. Since the reinforcing sheet metal 150 is formed with the screw holes 150h and 150i in the immediate vicinity of the external connection connector 140, it can be reduced in size. In an electronic device having radio waves such as a cellular phone, the reduction in size of the reinforcing sheet metal 150 has an effect of reducing the antenna sensitivity and the influence on noise. Further, since the reinforcing sheet metal 150 is formed with screw holes 150h and 150i in the immediate vicinity of the external connector 140, the amount of deformation of the bending of the reinforcing sheet metal 150 at the time of twisting can be reduced and the strength can be increased. it can.

図４は、補強板金１５０とケース１２０との取付けを示す斜視図であり、図５は、図４の要部拡大図である。図４は、ケース１２０を背面すなわち基板１２０側から見た図である。   4 is a perspective view showing attachment of the reinforcing sheet metal 150 and the case 120, and FIG. 5 is an enlarged view of a main part of FIG. FIG. 4 is a view of the case 120 as viewed from the back, that is, from the substrate 120 side.

図４に示すように、ケース１２０には、補強板金１５０及び外部接続コネクタ１４０を収納する収納部１２１が形成されている。収納部１２１は、補強板金１５０の引掛かり部１５０ｇが係止する補強板金引掛け部１２２と、補強板金１５０のストッパ部１５０ｆが当接する補強板金脱落防止リブ１２３と、を有する。   As shown in FIG. 4, the case 120 is formed with a storage portion 121 that stores the reinforcing sheet metal 150 and the external connection connector 140. The storage part 121 includes a reinforcing sheet metal hooking part 122 that the hooking part 150g of the reinforcing sheet metal 150 is engaged with, and a reinforcing sheet metal drop-off preventing rib 123 with which the stopper part 150f of the reinforcing sheet metal 150 abuts.

補強板金引掛け部１２２は、図５に示すように、断面コ字形状に形成されており、補強板金１５０の引掛かり部１５０ｇが挿入され、引掛かり部１５０ｇを引っ掛けて係止する。   As shown in FIG. 5, the reinforcing sheet metal hooking portion 122 is formed in a U-shaped cross section, and the hooking portion 150 g of the reinforcing metal plate 150 is inserted, and the hooking portion 150 g is hooked and locked.

補強板金脱落防止リブ１２３は、引掛かり部１５０ｇが挿入された補強板金１５０のストッパ部１５０ｆに当接して補強板金１５０の脱落を防止する。   The reinforcing sheet metal drop prevention rib 123 abuts against the stopper portion 150f of the reinforcing sheet metal 150 into which the hook portion 150g is inserted to prevent the reinforcing sheet metal 150 from falling off.

図６乃至図９は、ケース１２０への補強板金１５０の取付け方法を説明する図である。図６は、ケース１２０への補強板金１５０の取付けを示す斜視図、図７は、図６のＡ−Ａ矢視断面図である。図８は、ケース１２０への補強板金１５０の取付け後の状態を示す斜視図、図９は、図８のＡ−Ａ矢視断面図である。   6 to 9 are views for explaining a method of attaching the reinforcing sheet metal 150 to the case 120. 6 is a perspective view showing attachment of the reinforcing sheet metal 150 to the case 120, and FIG. 7 is a cross-sectional view taken along line AA in FIG. 8 is a perspective view showing a state after the reinforcing sheet metal 150 is attached to the case 120, and FIG. 9 is a cross-sectional view taken along line AA in FIG.

図６及び図７に示すように、ケース１２０の収納部１２１に補強板金１５０を配置する。この配置は、補強板金引掛け部１２２に、補強板金１５０の引掛かり部１５０ｇが向かい合う位置である。   As shown in FIGS. 6 and 7, the reinforcing sheet metal 150 is disposed in the storage part 121 of the case 120. This arrangement is a position where the catching portion 150 g of the reinforcing sheet metal 150 faces the reinforcing sheet metal hooking portion 122.

まず、ケース１２０の補強板金引掛け部１２２に、補強板金１５０の引掛かり部１５０ｇの先端を差し込んで引っ掛ける。   First, the front end of the catching part 150 g of the reinforcing sheet metal 150 is inserted into the reinforcing sheet metal hooking part 122 of the case 120 and hooked.

そして、図６及び図７矢印に示すように、補強板金１５０のネジ穴１５０ｈ側を押し込むと、引掛かり部１５０ｇは、補強板金引掛け部１２２の奥まで進入し、ストッパ部１５０ｆは、補強板金脱落防止リブ１２３の面取り部分を滑って収納部１２１底部まで押し込まれる。   6 and FIG. 7, when the screw hole 150h side of the reinforcing sheet metal 150 is pushed in, the hooking part 150g enters the depth of the reinforcing sheet metal hooking part 122, and the stopper part 150f is inserted into the reinforcing sheet metal. The chamfered portion of the drop-off prevention rib 123 is slid and pushed to the bottom of the storage unit 121.

図６及び図７に示すように、ストッパ部１５０ｆが、収納部１２１底部まで押し込まれると、ケース１２０への補強板金１５０の取付けは終了する。この状態では、ストッパ部１５０ｆの端面は、ストッパ部１５０ｆの側面にほぼ垂直で当接するので、当接した面同士が簡単に離れることはない。このため、ストッパ部１５０ｆは、収納部１２１から飛び出すことはなく、補強板金１５０は、ケース１２０の収納部１２１に、確実に取り付けられた状態となる。   As shown in FIGS. 6 and 7, when the stopper portion 150f is pushed down to the bottom of the storage portion 121, the attachment of the reinforcing sheet metal 150 to the case 120 is finished. In this state, the end surfaces of the stopper portion 150f abut substantially perpendicularly to the side surfaces of the stopper portion 150f, so that the abutted surfaces are not easily separated from each other. For this reason, the stopper portion 150 f does not jump out of the storage portion 121, and the reinforcing sheet metal 150 is securely attached to the storage portion 121 of the case 120.

このように、補強板金１５０は、ケース１２０には簡単に取り付けられるが、抜けない構造となっている。   As described above, the reinforcing sheet metal 150 is easily attached to the case 120, but has a structure that does not come off.

また、ケース１２０の組み立てと同時に補強板金１５０が取り付けられるので、組み立てが簡単である利点がある。また、補強板金引掛け部１２２や補強板金脱落防止リブ１２３は、ケース１２０側で構成されるので、補強板金１５０の形状は単純であり、保持のための曲げ加工も不要である。さらに、補強板金１５０は、直接ケース１２０に取り付けられるので、取り付けるための粘着テープなどの別部品が不要という利点がある。   Further, since the reinforcing sheet metal 150 is attached simultaneously with the assembly of the case 120, there is an advantage that the assembly is easy. Further, since the reinforcing sheet metal hooking portion 122 and the reinforcing sheet metal drop prevention rib 123 are configured on the case 120 side, the shape of the reinforcing sheet metal 150 is simple, and bending processing for holding is unnecessary. Further, since the reinforcing sheet metal 150 is directly attached to the case 120, there is an advantage that a separate part such as an adhesive tape for attachment is unnecessary.

以上詳細に説明したように、本実施の形態の携帯端末装置１００の筐体１１０は、ケース１２０と、ケース１２０に組み込まれる基板１３０と、基板１３０に底面側が取り付けられた外部接続コネクタ１４０と、外部接続コネクタ１４０の周囲を底面１４０ｂ以外の三方面から囲んで補強する補強板金１５０と、ケース１２０に装着されるカバー１６０と、を備える。補強板金１５０は、外部接続コネクタ１４０の底面１４０ｂ以外の周囲を外形近似した折曲部１５０ａ−１５０ｄを有する。また、ケース１２０、補強板金１５０、基板１３０、及びカバー１６０は、ネジ１０１により共締めして固定される。   As described above in detail, the housing 110 of the mobile terminal device 100 of the present embodiment includes the case 120, the substrate 130 incorporated in the case 120, the external connection connector 140 attached to the substrate 130 on the bottom surface side, A reinforcing sheet metal 150 that surrounds and reinforces the periphery of the external connection connector 140 from three sides other than the bottom surface 140b and a cover 160 that is attached to the case 120 are provided. The reinforcing sheet metal 150 has bent portions 150a to 150d whose outer shape is approximate to the periphery of the external connection connector 140 other than the bottom surface 140b. The case 120, the reinforcing sheet metal 150, the substrate 130, and the cover 160 are fixed together by screws 101.

この構成により、外部接続コネクタ１４０は、補強板金１５０で覆われ、かつ基板１３０との間で挟み押さえ込まれることで、コジリ強度を高めることができる。また、ケース１２０、補強板金１５０、基板１３０、及びカバー１６０を共締めして固定することで、筐体１１０の強度を取り込むことができ、より一層コジリ強度を向上させることができる。   With this configuration, the external connection connector 140 is covered with the reinforcing sheet metal 150 and is sandwiched and pressed between the substrate 130 and the strength of the connection can be increased. Moreover, the case 120, the reinforcing sheet metal 150, the substrate 130, and the cover 160 are fastened together and fixed, whereby the strength of the housing 110 can be taken in and the squeezing strength can be further improved.

また、補強板金１５０が小型化されるので、本外部接続コネクタの補強構造を、携帯電話等の電波を有する電子機器に適用した場合、アンテナ感度やノイズへの影響を小さくすることができる。   Further, since the reinforcing sheet metal 150 is reduced in size, when the reinforcing structure of the external connection connector is applied to an electronic device having radio waves such as a mobile phone, the influence on the antenna sensitivity and noise can be reduced.

本実施の形態では、共締めのネジ１０１の位置を、外部接続コネクタ１４０の直近に配置したので、補強板金１５０の撓みによる変形量をより少なくすることができ、コジリ強度をより一層高めることができる。   In the present embodiment, since the position of the joint screw 101 is arranged in the immediate vicinity of the external connection connector 140, the amount of deformation due to the bending of the reinforcing sheet metal 150 can be reduced, and the squeeze strength can be further increased. it can.

また、補強板金１５０は、ケース１２０の収納部１２１に、簡単に組み込まれるので、組み立て性の向上を図ることができる。因みに、基板１３０側に、補強板金１５０を取り付けようとする場合には、補強板金１５０を取り付けた基板１３０を、ケース１２０に組み込むまでの間の保持が困難である。   Further, since the reinforcing sheet metal 150 is easily incorporated into the housing part 121 of the case 120, the assemblability can be improved. Incidentally, when the reinforcing sheet metal 150 is to be attached to the substrate 130 side, it is difficult to hold the substrate 130 to which the reinforcing sheet metal 150 is attached until it is incorporated into the case 120.

さらに、補強板金１５０を両面テープ等の別部品を用いることなく、ワンタッチで取り付けることができ、補強板金１５０の組み立て性をより一層向上させることができる。   Further, the reinforcing sheet metal 150 can be attached with one touch without using another part such as a double-sided tape, and the assemblability of the reinforcing sheet metal 150 can be further improved.
