　近年、携帯端末の機能は多様化し、１つの携帯端末に複数のアンテナが設けられるようになっている。特許文献１のような携帯端末では、パッキン内部に１つのアンテナを設けることができるものの、他のアンテナはパッキンよりも内側でかつ他の金属部品と離れた場所に設けなければならない。このため、他のアンテナの設置が困難になる。 In recent years, the functions of mobile terminals have diversified, and a plurality of antennas are provided in one mobile terminal. In a portable terminal such as Patent Document 1, one antenna can be provided inside the packing, but the other antenna must be provided inside the packing and at a location away from other metal parts. This makes it difficult to install other antennas.
　また、特許文献２の携帯無線機においても１つのフレキシブルプリント基板しか設けられておらず、他のアンテナは、防水パッキンの内側の別の場所に設けなければならない。しかも、フレキシブルプリント基板であるため、撓みやすく、防水パッキンの取付の際にフレキシブルプリント基板の取り回しが困難であると共に、薄い基材の一方の面にしかアンテナをプリントできず、基板の接続方法もコネクタなどに限定されて設計自由度が低いという問題があった。 Also, the portable wireless device of Patent Document 2 is provided with only one flexible printed circuit board, and the other antennas must be provided at different locations inside the waterproof packing. Moreover, because it is a flexible printed circuit board, it is easy to bend, and it is difficult to handle the flexible printed circuit board when attaching the waterproof packing, and the antenna can be printed only on one side of a thin base material, and the connection method of the circuit board is also There was a problem that the degree of freedom in design was low due to being limited to connectors.
　本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、アンテナを狭いスペースに容易に配置することにある。 The present invention has been made in view of such a point, and an object of the present invention is to easily arrange an antenna in a narrow space.
　上記の目的を達成するために、この発明では、キャビネットの溝部に嵌め込まれるベース部に一体に設けた立体的な樹脂部材にアンテナ部を設けた。 In order to achieve the above object, in the present invention, an antenna portion is provided on a three-dimensional resin member provided integrally with a base portion fitted in a groove portion of a cabinet.

　上記携帯端末本体に設けられ、給電接点を有する基板と、
　上記キャビネットの周縁に設けられた溝部と、
　上記溝部に嵌め込まれる弾性部材よりなるベース部と、
　上記ベース部に一体に連続する立体形状の樹脂部材と、
　上記樹脂部材の表面に設けられ、上記給電接点によって給電されるアンテナ部とを備えている。 Specifically, in the first invention, a cabinet constituting a part of the mobile terminal body,

A base portion made of an elastic member fitted into the groove portion;
A three-dimensional resin member integrally continuous with the base portion;
And an antenna portion that is provided on the surface of the resin member and is fed by the feeding contact.
　上記の構成によると、立体形状の樹脂部材の表面にアンテナ部を設けているので、フレキシブルプリント基板では実現できない立体的なアンテナ部の配置が可能となり、狭い位置で長いアンテナ部を設けることができると共に、給電接点の設計自由度が上がる。また、立体形状の樹脂部材をベース部に一体に成形し、その樹脂部材にアンテナ部を設けているので、ベース部を溝部に嵌め込めば、アンテナ部を給電接点のある位置に簡単に配置でき、この給電接点に直接当接させることができるので、アンテナ部に接続端子を設ける必要がなく、給電接点とアンテナ部との接続が極めて容易である。また、アンテナ部をキャビネットとは別体に設けているので、キャビネット単体の単価が安くなり、色々なバリエーションのカラーのキャビネットを用意することができると共に、アンテナが故障したときの取替が容易である。 According to the above configuration, since the antenna portion is provided on the surface of the three-dimensional resin member, it is possible to dispose a three-dimensional antenna portion that cannot be realized with a flexible printed board, and a long antenna portion can be provided in a narrow position. At the same time, the design flexibility of the power supply contact increases. In addition, a three-dimensional resin member is molded integrally with the base part, and the antenna part is provided on the resin part. Therefore, if the base part is fitted into the groove part, the antenna part can be easily placed at the position where the feeding contact is located. Since it can be brought into direct contact with the power supply contact, there is no need to provide a connection terminal on the antenna portion, and the connection between the power supply contact and the antenna portion is extremely easy. In addition, since the antenna unit is provided separately from the cabinet, the unit price of the cabinet alone is reduced, and various color cabinets can be prepared, and replacement when the antenna breaks down is easy. is there.

　以下、本発明の実施形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図２は本発明の実施形態の携帯端末としての携帯電話機１を示す。この携帯電話機１は、表示部２が設けられた第１の筐体３と、表面に操作部４を有する携帯端末本体としてのこの第２の筐体５とを備え、これら第１の筐体３と第２の筐体５とがヒンジ部６を介して折畳み開閉可能に連結されている。 FIG. 2 shows a mobile phone 1 as a mobile terminal according to an embodiment of the present invention. The mobile phone 1 includes a first casing 3 provided with a display unit 2 and a second casing 5 as a mobile terminal body having an operation unit 4 on the surface thereof. 3 and the second housing 5 are connected via a hinge portion 6 so as to be foldable.
　図１に示すように、第２の筐体５は、操作部４の操作キー７が設けられる表側キャビネット８と、この表側キャビネット８の裏側に嵌め込まれる裏側キャビネット９とを備えている。 As shown in FIG. 1, the second housing 5 includes a front cabinet 8 provided with an operation key 7 of the operation unit 4, and a back cabinet 9 fitted into the back side of the front cabinet 8.
　図１０に示すように、表側キャビネット８には、給電接点１０を有する基板１１が嵌め込まれている。給電接点１０は、例えば裏側キャビネット９の左右側壁側に１箇所、上側に２箇所の合計３箇所に設けられている。なお、図３では、簡略化のために基板１１は省略している。 As shown in FIG. 10, a substrate 11 having a feeding contact 10 is fitted in the front cabinet 8. The power supply contacts 10 are provided at a total of three places, for example, one place on the left and right side walls of the back cabinet 9 and two places on the upper side. In FIG. 3, the substrate 11 is omitted for simplification.
　図７に示すように、裏側キャビネット９の上下左右周縁には、全周にわたり、溝部１２が形成されている。具体的には、この溝部１２は、裏側キャビネット９に収容する部品の配置に合わせて厚さ方向に高低差があるように連続して設けられている。 As shown in FIG. 7, grooves 12 are formed on the upper, lower, left, and right peripheral edges of the back cabinet 9 over the entire periphery. Specifically, the groove 12 is continuously provided so that there is a height difference in the thickness direction in accordance with the arrangement of the components accommodated in the back cabinet 9.
　図４及び図５に示すように、この溝部１２には、防水パッキン２０が嵌合されている。具体的には、図１、図３、図６及び図９に示すように、防水パッキン２０は、シリコンなどの弾性部材よりなる環状のベース部２１を有し、このベース部２１の外周の一部（例えば上下左右の内側）に適度な弾性を有するポリカーボネイト樹脂よりなる樹脂部材２２（図面では、見やすくするために斜線を加えている）が一体成形されている。この樹脂部材２２は、溝部１２の高低差に合わせた立体形状を有する。樹脂部材２２をポリカーボネイトで構成することで、適度な剛性及び柔軟性を与えてベース部２１の形状保持を容易にすることができる。ベース部２１の全周にわたり樹脂部材２２を設けてもよいが、例えば、図６に示すように、左右１箇所ずつ樹脂部材２２を設けない部分（調整部２４）がある方が、この調整部２４が溝部１２の全長と、防水パッキン２０の全長との誤差を吸収できて望ましい。ベース部２１だけでは、撓みすぎて一定の形状を保つことはできないが、このシリコンなどのベース部２１よりも剛性が高い樹脂部材２２により、防水パッキン２０の形状がある程度保たれている。 As shown in FIGS. 4 and 5, a waterproof packing 20 is fitted in the groove 12. Specifically, as shown in FIGS. 1, 3, 6, and 9, the waterproof packing 20 has an annular base portion 21 made of an elastic member such as silicon, and an outer periphery of the base portion 21. A resin member 22 (in the drawing, hatched lines are added for ease of viewing) made of polycarbonate resin having appropriate elasticity is formed integrally with the portion (for example, inside of the top, bottom, left, and right). The resin member 22 has a three-dimensional shape that matches the height difference of the groove 12. By configuring the resin member 22 with polycarbonate, it is possible to easily maintain the shape of the base portion 21 by giving appropriate rigidity and flexibility. The resin member 22 may be provided over the entire circumference of the base portion 21. For example, as shown in FIG. 6, the adjustment portion has a portion (adjustment portion 24) where the resin member 22 is not provided on each of the left and right sides. 24 is desirable because it can absorb an error between the total length of the groove 12 and the total length of the waterproof packing 20. Although the base portion 21 alone is too flexible to maintain a certain shape, the shape of the waterproof packing 20 is maintained to some extent by the resin member 22 having a higher rigidity than the base portion 21 such as silicon.
　そして、このベース部２１に沿う樹脂部材２２の一部には、ベース部２１が収まるほぼ一定幅の溝部１２よりも幅の大きい２つの膨出部２３が設けられている。なお、膨出部２３の部分の溝部１２が膨らんで、この膨らんだ溝部１２内に膨出部２３が収まっていてもよい。これら膨出部２３は、給電接点１０に合わせて間隔をあけて設けられ、各膨出部２３の表面に給電接点１０によって給電されるアンテナ部２５（見やすくするためにクロスハッチングで示す）が設けられている。アンテナ部２５の形状は、受信する信号によって異なるが、膨出部２３の形状が立体形状であるので、例えばその表面に蛇行させて導電性インクを印刷してアンテナ部２５を設ければ、アンテナ部２５の長さを確保しやすい。そして、図６に示すように、１つの膨出部２３に間隔をあけて２つ以上のアンテナ部２５を導電印刷して配置することもできる。アンテナ部２５は、例えば、通話用アンテナ、ブルートゥース（ＢＴ）、無線ＬＡＮ、ＧＰＳ、ＦＭトランスミッタ、ＮＦＣ（Near Field Communication）よりなる。導電性インクを印刷するのではなく、導電性塗料を塗布するようにしてもよい。なお、膨出部２３の導電印刷する部分をＡＢＳ樹脂で二色成形し、その部分に導電性のある金属のメッキを施してもよい。これにより、メッキの密着性がよくなって剥がれにくなる。 And, a part of the resin member 22 along the base portion 21 is provided with two bulging portions 23 having a larger width than the groove portion 12 having a substantially constant width in which the base portion 21 is accommodated. In addition, the groove part 12 of the part of the bulging part 23 may swell, and the bulging part 23 may be contained in this swelled groove part 12. These bulges 23 are provided at intervals in accordance with the power feed contacts 10, and antenna parts 25 (shown by cross-hatching for the sake of clarity) are provided on the surfaces of the bulges 23 by the power feed contacts 10. It has been. The shape of the antenna unit 25 varies depending on the signal to be received. However, since the shape of the bulging unit 23 is a three-dimensional shape, for example, if the antenna unit 25 is provided by meandering the surface and printing conductive ink, the antenna It is easy to secure the length of the portion 25. And as shown in FIG. 6, the two or more antenna parts 25 can also be electrically printed and arrange | positioned at intervals in one bulging part 23. As shown in FIG. The antenna unit 25 includes, for example, a call antenna, Bluetooth (BT), wireless LAN, GPS, FM transmitter, and NFC (Near Field Communication). Instead of printing the conductive ink, a conductive paint may be applied. The conductive printing portion of the bulging portion 23 may be two-color molded with ABS resin, and the portion may be plated with conductive metal. As a result, the adhesion of the plating is improved and peeling becomes difficult.
　なお、膨出部２３に板金等よりなるアンテナ部２５の一部を埋め込むようにインサート成形してもよい。 In addition, you may insert-mold so that a part of antenna part 25 which consists of sheet metal etc. may be embedded in the bulging part 23. FIG.
　一方、図９に示すように、基板１１表面に設けた給電接点１０は、例えば図示しない弾性部材でアンテナ部２５へ付勢される給電ピンよりなり、アンテナ部２５は、この給電接点１０が押しつけられて給電されるように構成されている。つまり、膨出部２３が立体的な形状をしているので、弾性を有する給電接点１０を当接させることができるようになっている。このため、アンテナ部２５に接続をするためのコネクタなどの端子を設ける必要がない。 On the other hand, as shown in FIG. 9, the power supply contact 10 provided on the surface of the substrate 11 includes, for example, a power supply pin that is urged to the antenna unit 25 by an elastic member (not shown), and the antenna unit 25 is pressed against the power supply contact 10. And is supplied with power. That is, since the bulging portion 23 has a three-dimensional shape, the power feeding contact 10 having elasticity can be brought into contact therewith. For this reason, it is not necessary to provide a terminal such as a connector for connecting to the antenna unit 25.
　このように構成することにより、立体形状の膨出部２３の表面にアンテナ部２５を設けているので、フレキシブルプリント基板では実現できない立体的なアンテナ部２５の配置が可能となり、狭い位置で長いアンテナ部２５を設けることができると共に、給電接点１０の設計自由度が上げることができる。 With this configuration, since the antenna portion 25 is provided on the surface of the three-dimensional bulging portion 23, it is possible to arrange the three-dimensional antenna portion 25 that cannot be realized with a flexible printed board, and a long antenna in a narrow position. The portion 25 can be provided, and the design flexibility of the power supply contact 10 can be increased.
　また、樹脂部材２２を防水パッキン２０に沿って一体に設けることで、立体的な形状を保つことができるので、防水パッキン２０を溝部１２に嵌め込むのが極めて容易となり、防水パッキン２０が噛み込まないので、防水パッキン２０の寿命が延びる。 In addition, since the three-dimensional shape can be maintained by integrally providing the resin member 22 along the waterproof packing 20, it is very easy to fit the waterproof packing 20 into the groove portion 12, and the waterproof packing 20 is bitten. Therefore, the life of the waterproof packing 20 is extended.
　また、防水パッキン２０を溝部１２に嵌め込めば、アンテナ部２５を給電接点１０のある位置に簡単に配置でき、この給電接点１０に直接当接させることができるので、アンテナ部２５に接続端子を設ける必要がなく、給電接点１０とアンテナ部２５との接続が極めて容易である。 Further, if the waterproof packing 20 is fitted into the groove portion 12, the antenna portion 25 can be easily disposed at a position where the power supply contact 10 is located, and can be brought into direct contact with the power supply contact 10. Therefore, a connection terminal is connected to the antenna portion 25. There is no need to provide it, and the connection between the feeding contact 10 and the antenna unit 25 is extremely easy.
　また、アンテナ部２５を裏側キャビネット９とは別体に設けているので、裏側キャビネット９単体の単価が安くなり、色々なバリエーションのカラーの裏側キャビネット９を用意することができると共に、アンテナが故障したときの取替が容易である。 Further, since the antenna unit 25 is provided separately from the back side cabinet 9, the unit price of the back side cabinet 9 can be reduced, and various types of back side cabinets 9 of various colors can be prepared, and the antenna has failed. It is easy to replace when.

FIG. 11 shows a first modification of the embodiment of the present invention, which differs from the first embodiment in that the configuration of the power supply contact 10 is different. In the following modifications, the same parts as those in FIGS. 1 to 10 are denoted by the same reference numerals and detailed description thereof is omitted.
　すなわち、給電接点１０を板バネ１１０で構成してもよい。この板バネ１１０を基板１１の表面に弾性を有するように設けて膨出部２３の裏面側のアンテナ部２５を押さえ付けるようにしてもよい。この場合も、接触により給電可能となっているので、フレキシブルプリント基板のように端子を接続する必要はない。 That is, the power supply contact 10 may be constituted by the leaf spring 110. The leaf spring 110 may be provided on the surface of the substrate 11 so as to have elasticity, and the antenna portion 25 on the back surface side of the bulging portion 23 may be pressed. Also in this case, since power can be supplied by contact, it is not necessary to connect terminals like a flexible printed circuit board.
　－実施形態の変形例２－
　図１２に示すように、基板１１の裏面側から板バネ１１０を延ばし、板バネ１１０によって膨出部２３の裏面側のアンテナ部２５を押さえ付けるようにしてもよい。この場合には、基板１１とアンテナ部２５との位置が基板１１の厚さ方向で同等の位置にあるので、第２の筐体５の厚さを薄くすることができる。 -Modification Example 2-
As shown in FIG. 12, the leaf spring 110 may be extended from the back surface side of the substrate 11, and the antenna portion 25 on the back surface side of the bulging portion 23 may be pressed by the leaf spring 110. In this case, since the positions of the substrate 11 and the antenna unit 25 are in the same position in the thickness direction of the substrate 11, the thickness of the second housing 5 can be reduced.
　－実施形態の変形例３－
　図１３に示すように、膨出部２２３のベース部２１と反対側の表面（左右内側表面）２２３ａにアンテナ部２５を設けてもよい。この場合には、図９のようにアンテナ部２５と給電接点１０とを厚さ方向に上下に並べる必要がないので、膨出部２２３、給電接点２１０及びその周辺の厚さを薄くすることができ、第２の筐体５全体の厚さが減って携帯性を向上させることができる。 —Modification 3 of Embodiment—

In this case, as shown in FIG. 9, it is not necessary to arrange the antenna part 25 and the power supply contact 10 vertically in the thickness direction, so that the bulging part 223, the power supply contact 210 and the surrounding thickness can be reduced. In addition, the thickness of the entire second housing 5 can be reduced and portability can be improved.
　－実施形態の変形例４－
　図１４に示すように、膨出部３２３に基板１１を挟み込む凹部３２３ａを形成し、この凹部３２３ａの対向する表面にアンテナ部２５をそれぞれ設けてもよい。この構成によると、膨出部３２３と基板１１とを厚さ方向で同じ高さに配置でき、２つのアンテナ部２５が１つの膨出部３２３に設けられるので、ベース部２１を溝部１２に嵌め込んだときに、膨出部３２３の２つのアンテナ部２５をそれぞれの給電接点３１０に容易に接続することができるので、省スペース及び組立工数低減の観点で望ましい。 —Modification 4 of Embodiment—
As shown in FIG. 14, a recess 323 a that sandwiches the substrate 11 may be formed in the bulging portion 323, and the antenna portion 25 may be provided on the opposing surface of the recess 323 a. According to this configuration, the bulging portion 323 and the substrate 11 can be arranged at the same height in the thickness direction, and the two antenna portions 25 are provided in one bulging portion 323. Therefore, the base portion 21 is fitted into the groove portion 12.
