Description

本発明は、携帯電話、小型テレビ、小型ラジオなど、外観面の一部を構成するアンテナと板金筐体を有する携帯機器に関する。   The present invention relates to a portable device having an antenna and a sheet metal housing that constitute a part of an external surface, such as a mobile phone, a small television, and a small radio.

近時、携帯端末の小型化及び薄型化が進行しており、このため、筐体の一部にステンレス合金等の薄くて高剛性な金属板が使用されるようになってきた。この金属板は、プレス加工等の板金により、成形されている。アンテナについては、アンテナ特性に影響を与えないようにするため、アンテナ素子と周囲の金属類は一定の距離を設ける必要があることから、装置の小型化を実現するためには、実装場所が限定され、板金製の筐体の嵌合部をアンテナ側に大きく突出させることができないという問題点がある。このように、端末の小型化及び薄型化と、無線特性確保との両立のため、アンテナ素子と周囲の金属類は一定の距離を設ける必要があるために、筐体の外観面に露出して配置されることがある。   Recently, mobile terminals have been made smaller and thinner, and for this reason, a thin and highly rigid metal plate such as a stainless alloy has been used for a part of the housing. This metal plate is formed by sheet metal such as press working. As for the antenna, it is necessary to provide a certain distance between the antenna element and the surrounding metals so as not to affect the antenna characteristics. However, there is a problem that the fitting portion of the sheet metal casing cannot be protruded greatly toward the antenna side. As described above, in order to achieve both the miniaturization and thinning of the terminal and ensuring the wireless characteristics, the antenna element and the surrounding metal need to be provided with a certain distance. May be placed.

一方、板金製の筐体とアンテナが隣接した配置の場合、上述のアンテナ素子と周囲の金属類間の距離確保のため、嵌合フック等を筐体から突出させることができない。しかし、このように、板金製の筐体と外観面に露出したアンテナが隣接して配置されている場合、アンテナと板金製の筐体間に嵌合部を設けないと、外力が加わったときにアンテナ及び筐体が変形し、板金製の筐体の端部が露出してしまうという問題点がある。   On the other hand, in the case where the sheet metal casing and the antenna are arranged adjacent to each other, a fitting hook or the like cannot be protruded from the casing in order to secure the distance between the antenna element and the surrounding metal. However, when the sheet metal housing and the antenna exposed on the exterior surface are arranged adjacent to each other as described above, an external force is applied unless a fitting portion is provided between the antenna and the sheet metal housing. In addition, there is a problem that the antenna and the casing are deformed, and the end portion of the casing made of sheet metal is exposed.

また、アンテナ側の樹脂部を延長して金属筐体に結合させようとした場合、結合部の実装スペースが必要であり、端末の小型化を阻害してしまうという問題点が生じる。   Further, when the antenna-side resin portion is extended to be coupled to the metal casing, a mounting space for the coupling portion is required, which causes a problem that miniaturization of the terminal is hindered.

特開２００４−３１７５８８号公報JP 2004-317588 A

本発明はかかる問題点に鑑みてなされたものであって、プレス成形等により得た筐体と、その筐体に隣接し外観面が樹脂で被覆されたアンテナで構成された携帯機器において、外力が加わったときに板金製等の金属板製筐体がめくれ難く、またアンテナ特性にも影響せず、かつ少ない実装スペースの中で実現できる構造の携帯機器を提供することを目的とする。   The present invention has been made in view of such a problem, and in a portable device including a casing obtained by press molding or the like and an antenna having an exterior surface coated with a resin adjacent to the casing, an external force is provided. An object of the present invention is to provide a portable device having a structure in which a metal plate housing such as a sheet metal is difficult to be turned over when added, and does not affect antenna characteristics and can be realized in a small mounting space.

本発明に係る携帯機器は、金属板製の第１の筐体と、この第１の筐体が重ね合わされて固定され内部に素子収納空間を形成する金属板製の第２の筐体と、前記第１の筐体に隣接する位置にて前記第２の筐体に固定され絶縁層で被覆されたアンテナとを有し、前記第１の筐体は、その前記アンテナ側の端縁に設けられ前方部分が後方部分より低い段付き形状のフック部を有し、前記アンテナは、その前記第１の筐体側の端縁に設けられ前記フック部が挿入される孔部を有し、前記フック部が前記孔部に挿入された状態で前記フック部の前記前方部分が前記孔部の周縁部に係止されることを特徴とする。   A portable device according to the present invention includes a first casing made of a metal plate, a second casing made of a metal plate that overlaps and fixes the first casing and forms an element storage space therein, and An antenna fixed to the second casing and covered with an insulating layer at a position adjacent to the first casing, and the first casing is provided at an edge of the antenna side The antenna has a stepped hook portion whose front portion is lower than the rear portion, and the antenna has a hole portion which is provided at an edge of the first housing side and into which the hook portion is inserted. The front part of the hook part is locked to the peripheral part of the hole part with the part inserted into the hole part.

本発明においては、金属板製の第１の筐体と第２の筐体とは、ねじ止め等により相互に固定されており、アンテナと第２の筐体とがねじ止め等により相互に固定されている。そして、フック部が第１の筐体に溶接等により固定されるか、又は第１の筐体に一体成形されており、このフック部をアンテナの孔部に挿入し、フック部の段付き形状の前方下段部を前記孔部の周縁部で係止させて、第１の筐体とアンテナとが相互に固定されている。このため、携帯機器に外力が作用し、アンテナと第１の筐体とが開く方向に応力が作用しても、前記フック部が前記孔部に係止されているので、第１の筐体がめくれてしまうことが防止される。また、アンテナ特性を劣化させず、実装スペースが小さくて済む。   In the present invention, the first casing and the second casing made of metal plates are fixed to each other by screwing or the like, and the antenna and the second casing are fixed to each other by screwing or the like. Has been. The hook portion is fixed to the first housing by welding or the like, or is integrally formed with the first housing, and the hook portion is inserted into the hole of the antenna to form a stepped shape of the hook portion. The first lower case and the antenna are fixed to each other by locking the front lower step portion of the first lower step portion at the peripheral edge portion of the hole portion. For this reason, even if an external force acts on the portable device and a stress acts in a direction in which the antenna and the first housing are opened, the hook portion is locked in the hole portion. It is prevented from turning over. Further, the antenna characteristics are not deteriorated, and the mounting space can be reduced.

本発明においては、前記フック部は前記第１の筐体とは別体で成形された金属板製の部材であり、前記第１の筐体に溶接により接合されたものであるか、又は前記フック部は前記第１の筐体と一体成形されたものであることが好ましい。   In the present invention, the hook portion is a member made of a metal plate formed separately from the first housing, and is joined to the first housing by welding, or The hook portion is preferably formed integrally with the first housing.

また、前記フック部を前記孔部に挿入し嵌合させた状態で、前記アンテナの面は前記第１の筐体の面よりも突出していることが好ましい。   Moreover, it is preferable that the surface of the antenna protrudes from the surface of the first housing in a state where the hook portion is inserted into the hole and fitted.

本発明によれば、携帯機器に外力が作用し、アンテナと第１の筐体とが開く方向に応力が作用しても、前記フック部が前記孔部に係止されているので、第１の筐体がめくれてしまうことが防止される。また、上記構造により、アンテナ特性を劣化させることがなく、また実装スペースが小さくて済み、端末の小型化を阻害することがない。   According to the present invention, even when an external force is applied to the portable device and a stress is applied in a direction in which the antenna and the first housing are opened, the hook portion is locked in the hole portion. It is possible to prevent the casing of the device from turning over. In addition, the above-described structure does not deteriorate the antenna characteristics, requires a small mounting space, and does not hinder downsizing of the terminal.

以下、本発明の実施の形態について、添付の図面を参照して具体的に説明する。図１は、本発明の第１の実施形態に係る携帯機器の組立斜視図、図２は組立後の斜視図、図３（ａ）乃至（ｃ）はその動作を示す図２のＡ−Ａ線による断面図である。   Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings. 1 is an assembled perspective view of a portable device according to the first embodiment of the present invention, FIG. 2 is a perspective view after assembly, and FIGS. 3A to 3C are AA views of FIG. It is sectional drawing by a line.

第１の筐体１及び第２の筐体３は、金属板をプレス成形等の板金により箱状に成形したものである。第２の筐体３はその１方の端部の若干の部分が側壁が若干高いものとなっている。そして、第２の筐体３の側壁が低い部分に、第１の筐体１の側壁が重ねられて、第１の筐体１及び第２の筐体３により囲まれた空間に、素子が収納されるようになっている。アンテナ２は第１の筐体１に隣接するように配置され、第２の筐体３の側壁の若干高い部分に重ねられている。アンテナ２はその外観が絶縁層としての樹脂で被覆されており、金属板製の第１の筐体１及び第２の筐体３に接触しても、アンテナ特性が劣化することはない。   The 1st housing | casing 1 and the 2nd housing | casing 3 shape | mold a metal plate in box shape with sheet metal, such as press molding. As for the 2nd housing | casing 3, the one part of the one end part has a slightly high side wall. Then, the side wall of the first housing 1 is overlapped on the portion where the side wall of the second housing 3 is low, and the element is placed in the space surrounded by the first housing 1 and the second housing 3. It is designed to be stored. The antenna 2 is disposed so as to be adjacent to the first housing 1 and is superimposed on a slightly higher portion of the side wall of the second housing 3. The external appearance of the antenna 2 is covered with a resin as an insulating layer, and the antenna characteristics do not deteriorate even if the antenna 2 contacts the first casing 1 and the second casing 3 made of metal plates.

第２の筐体３の４隅部には、ボルト４ａ、４ｂが螺合するねじ孔付きのボス３１，３２が設けられている。また、第１の筐体１のアンテナ２から離れた側の端部には、ボルト４ａが挿通する孔１２が形成されており、この孔１２にボルト４ｂを挿入し、孔１２を挿通してボルト４ｂをボス３２のねじ孔に螺合させることにより、第１の筐体１が第２の筐体３に固定されるようになっている。また、アンテナ２の第１の筐体１側の端部には、ボルト４ｂが挿通する孔２２が形成されており、この孔２２にボルト４ａを挿入し、孔２２を挿通してボルト４ａをボス３１のねじ孔に螺合させることにより、アンテナ２が第２の筐体３に固定されるようになっている。   Bosses 31 and 32 with screw holes into which bolts 4 a and 4 b are screwed are provided at the four corners of the second housing 3. In addition, a hole 12 through which the bolt 4a is inserted is formed at the end of the first casing 1 on the side away from the antenna 2, and the bolt 4b is inserted into the hole 12 and the hole 12 is inserted through the hole 12. The first casing 1 is fixed to the second casing 3 by screwing the bolts 4 b into the screw holes of the bosses 32. A hole 22 through which the bolt 4b is inserted is formed at the end of the antenna 2 on the first housing 1 side. The bolt 4a is inserted into the hole 22, and the bolt 4a is inserted through the hole 22. The antenna 2 is fixed to the second housing 3 by being screwed into the screw hole of the boss 31.

第１の筐体１のアンテナ２側の端部１３には、２個のフック部１１が設けられている。このフック部１１は、断面がカギ形又はクランク形状をなし、後方部分が高く、前方部分が低い段付き形状をなしている。そして、このフック部１１は、第１の筐体１と同様に金属板のプレス成形により成形されており、後方の上段部分が第１の筐体１の内面にスポット溶接等により固定されている。一方、アンテナ２の第１の筐体１側の端部２３には、平面視でコ字状の孔部２１が、アンテナ２の端面から突出するようにして形成されている。これにより、孔部２１は、アンテナ２の端部２３と共に、４辺が囲まれた矩形の孔を構成している。   Two hook portions 11 are provided at the end 13 on the antenna 2 side of the first housing 1. The hook portion 11 has a stepped shape with a cross section having a key shape or a crank shape, a high rear portion, and a low front portion. And this hook part 11 is shape | molded by the press molding of a metal plate similarly to the 1st housing | casing 1, The back upper stage part is being fixed to the inner surface of the 1st housing | casing 1 by spot welding etc. . On the other hand, a U-shaped hole 21 in a plan view is formed at the end 23 of the antenna 2 on the first housing 1 side so as to protrude from the end surface of the antenna 2. Thereby, the hole 21 constitutes a rectangular hole surrounded by four sides together with the end 23 of the antenna 2.

上述の如く構成されたアンテナ２，第１の筐体１及び第２の筐体３は、以下のようにして組み立てられる。先ず、アンテナ２を第２の筐体３の上に重ね、ボルト４ａを孔２２に挿通させて、第２の筐体３のボス３１のねじ孔に螺合させる。そして、第１の筐体１のフック部１１を孔部２１内に挿入しフック部１１の前方部分の下段部分を孔部２１の周縁部の下面に係止させる。この状態で、アンテナ２の上面と、第１の筐体１の上面とが、ほぼ面一になり、ボルト４ｂを孔１２に挿通させて第２の筐体３のボス３２のねじ孔に螺合させる。これにより、第１の筐体１及びアンテナ２と第２の筐体３とが固定され、更に、アンテナ２と第１の筐体１とが係合固定される。   The antenna 2, the first casing 1 and the second casing 3 configured as described above are assembled as follows. First, the antenna 2 is stacked on the second housing 3, and the bolt 4 a is inserted through the hole 22 and screwed into the screw hole of the boss 31 of the second housing 3. Then, the hook portion 11 of the first housing 1 is inserted into the hole portion 21 and the lower portion of the front portion of the hook portion 11 is locked to the lower surface of the peripheral portion of the hole portion 21. In this state, the upper surface of the antenna 2 and the upper surface of the first housing 1 are substantially flush with each other, and the bolt 4 b is inserted into the hole 12 and screwed into the screw hole of the boss 32 of the second housing 3. Combine. Thereby, the 1st housing | casing 1 and the antenna 2 and the 2nd housing | casing 3 are fixed, and also the antenna 2 and the 1st housing | casing 1 are engaged and fixed.

図３（ａ）に示すように、各部材が組み立てられた状態で、アンテナ２の上面と、第１の筐体１の上面とがほぼ面一になっている。これに対し、図３（ｂ）に示すように、この携帯機器に、外力が作用した場合、アンテナ２と第１及び第２の筐体１，３との間には、アンテナ２と第１の筐体１とが離隔する方向の応力がアンテナ２と第１の筐体１との間の境界２９に作用する。これにより、第１の筐体１のアンテナ２側の端部１３が持ち上がろうとするが、第１の筐体１に固定されたフック部１１の前方部分の下段部分がアンテナ２の孔部２１の下面に係止されているので、第１の筐体１の端部１３が持ち上がることはない。これにより、第１の筐体１がめくれ上がることがない。従って、外力が作用しても、第１の筐体１の端部１３の角部が外面に露出することが抑制される。また、本実施形態においては、この結合部により、携帯機器が大型化することもなく、アンテナ特性が劣化することもない。   As shown in FIG. 3A, the upper surface of the antenna 2 and the upper surface of the first housing 1 are substantially flush with each other in the assembled state. On the other hand, as shown in FIG. 3 (b), when an external force is applied to the portable device, the antenna 2 and the first housing 1 are placed between the antenna 2 and the first and second housings 1 and 3. The stress in the direction away from the casing 1 acts on the boundary 29 between the antenna 2 and the first casing 1. As a result, the end portion 13 on the antenna 2 side of the first housing 1 tries to lift up, but the lower portion of the front portion of the hook portion 11 fixed to the first housing 1 is the hole portion of the antenna 2. Since it is latched by the lower surface of 21, the edge part 13 of the 1st housing | casing 1 does not lift. Thereby, the 1st housing | casing 1 does not turn up. Therefore, even when an external force is applied, the corner portion of the end portion 13 of the first housing 1 is suppressed from being exposed to the outer surface. In the present embodiment, the coupling portion does not increase the size of the mobile device and does not deteriorate the antenna characteristics.

よって、本発明によれば、外力が加わったときに板金筐体の嵌合端面がめくれ難い嵌合構造が得られる。そして、上記嵌合構造をアンテナ特性に影響を与えないで且つ、少ない実装スペースの中で実現することができる。   Therefore, according to the present invention, it is possible to obtain a fitting structure in which the fitting end surface of the sheet metal housing is difficult to turn when an external force is applied. The fitting structure can be realized in a small mounting space without affecting the antenna characteristics.

次に、本発明の第２実施形態について説明する。図４に示すように、本実施形態においては、アンテナ２，第１及び第２の筐体１，３を組み立てた状態で、アンテナ２の上面と、第１の筐体１の上面とは、若干の段差Ｃを有している。   Next, a second embodiment of the present invention will be described. As shown in FIG. 4, in the present embodiment, the antenna 2, the first and second casings 1 and 3 are assembled, and the top surface of the antenna 2 and the top surface of the first casing 1 are It has a slight level difference C.

本実施形態も第１実施形態と同様の効果を奏するが、本実施形態においては、第１の筐体１の上面がアンテナ２の上面より、Ｃだけ下方になるように段差が設けられているので、外力が作用したときに、第１の筐体１のアンテナ２側の端部が境界２９でアンテナ２の上面より上方に突出することがより一層確実に防止される。   This embodiment also has the same effect as the first embodiment, but in this embodiment, a step is provided so that the upper surface of the first housing 1 is below the upper surface of the antenna 2 by C. Therefore, when an external force is applied, the end of the first housing 1 on the antenna 2 side is more reliably prevented from protruding above the upper surface of the antenna 2 at the boundary 29.

次に、本発明の第３実施形態について、図５を参照して説明する。本実施形態は、第１の筐体１のフック部１１を、第１の筐体１と別体で成形するのではなく、第１の筐体１の部分を金属板の打ち抜き及びプレス成形等により板金加工で製造する際に、第１の筐体１の金属板と同一の金属板の端部に図５に示す段差形状を形成することにより、第１の筐体１とフック部１１とを一体成形することができる。このように、フック部１１を第１の筐体１と一体成形することにより、加工時間及び加工費用を低減することができる。   Next, a third embodiment of the present invention will be described with reference to FIG. In the present embodiment, the hook portion 11 of the first housing 1 is not formed separately from the first housing 1, but a portion of the first housing 1 is punched out of a metal plate, press-molded, or the like. 5 by forming the step shape shown in FIG. 5 at the end of the same metal plate as the metal plate of the first housing 1, thereby producing the first housing 1 and the hook portion 11. Can be integrally molded. Thus, by integrally forming the hook part 11 with the first housing 1, the processing time and processing cost can be reduced.
