Under this condition, the antenna board (7) is inserted into an undercut part (3b) formed along the peripheral edge of a casing (3). In this way, even for a casing having an undercut at a side face part, an antenna element can be placed in the vicinity of the outermost peripheral part of the casing, thereby improving the performance.

Description

電子機器Electronics
　本発明は、筐体の内部にアンテナエレメントを有する電子機器に関し、特にその組付構造に関する。 The present invention relates to an electronic device having an antenna element inside a casing, and more particularly to an assembly structure thereof.
　従来より、通信機能を有する電子機器には、通信用のアンテナエレメントが設けられている。アンテナエレメントとして、伸縮式のものを伸長させて通信感度を向上させるものがある。 Conventionally, an electronic device having a communication function has been provided with an antenna element for communication. There is an antenna element that extends a telescopic type to improve communication sensitivity.
　一方、携帯電話機などの通信可能な携帯式の電子機器では、アンテナエレメントを露出させず、筐体の内部に内蔵するものが増えてきている。 On the other hand, there is an increasing number of portable electronic devices such as mobile phones that are built in the housing without exposing the antenna element.
　例えば、特許文献１の情報端末のように、アンテナエレメントを設けたアンテナユニットにコイルバネを有する給電部を備えることが知られている。このアンテナユニットは、一方の筐体の平面部（正面部又は背面部）に取付けられ、他方の筐体と挟み込まれるように組み立てられる。この情報端末では、筐体の側面付近にアンダーカットがないため、アンテナユニットを筐体の側面に近い部分に取り付ける場合であっても、筐体平面部に対して垂直方向から取り付けることができる。 For example, as in the information terminal of Patent Document 1, it is known that an antenna unit provided with an antenna element includes a power feeding unit having a coil spring. This antenna unit is attached to a flat surface portion (a front surface portion or a back surface portion) of one housing and is assembled so as to be sandwiched between the other housing. In this information terminal, since there is no undercut near the side surface of the housing, the antenna unit can be mounted from the vertical direction with respect to the housing flat surface portion even when the antenna unit is attached to a portion near the side surface of the housing.
特開２００３－２４９８０５号公報JP 2003-249805 A
　内蔵型のアンテナエレメントは性能（感度）確保のために、できるだけ筐体の外周近くに配置する必要がある。一方、電気的な接続を確保するためのアンテナ給電バネを破損させる恐れがあるため、組立時にアンテナユニットはアンテナ給電バネの取付面に対して垂直に組み立てられる必要がある。 ¡The built-in antenna element must be placed as close to the outer periphery of the housing as possible to ensure performance (sensitivity). On the other hand, since there is a risk of damaging the antenna feeding spring for ensuring electrical connection, the antenna unit needs to be assembled perpendicular to the mounting surface of the antenna feeding spring during assembly.
　また、筐体の構造は、デザイン上の制約などから、アンテナユニット等の内蔵部品を複数の筐体部品によって挟み込む構造ではなく、一体的な構造とする場合がある。さらに、一体的な構造とする場合には、成形条件や筐体内部への高密度な部品配置といった制約から、筐体周縁にアンダーカット部を形成することがある。 Also, the structure of the housing may be an integrated structure rather than a structure in which a built-in component such as an antenna unit is sandwiched between a plurality of housing components due to design restrictions. Furthermore, in the case of an integral structure, an undercut portion may be formed on the peripheral edge of the casing due to restrictions such as molding conditions and high-density component placement inside the casing.
　このように、アンダーカット部が存在する一体構造の筐体を用いる場合には、アンテナ給電バネの破損を防止するために、アンダーカット部の内側（例えば、外観パネル貼付面の内側）までしかアンテナ範囲を広げることができず、安定したアンテナ性能を確保することが困難だった。 In this way, when using an integrally structured housing with an undercut portion, the antenna is only extended to the inside of the undercut portion (for example, the inside of the external panel pasting surface) in order to prevent damage to the antenna feeding spring. The range could not be expanded, and it was difficult to ensure stable antenna performance.
　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、側面部にアンダーカットを有する筐体であっても、アンテナエレメントを筺体の最外周部付近に配置することができ、性能を向上させることができるようにすることにある。 The present invention has been made in view of such a point, and the object of the present invention is to arrange the antenna element in the vicinity of the outermost peripheral portion of the housing even if the housing has an undercut on the side surface. It is possible to improve the performance.
　上記の目的を達成するために、この発明では、予めアンテナ部材とアンテナ基板とをユニット組立してから筐体のアンダーカット部に挿入するようにした。 In order to achieve the above object, in the present invention, the antenna member and the antenna substrate are assembled in advance before being inserted into the undercut portion of the housing.
　具体的には、本発明では、筐体の内部にアンテナエレメントを有する電子機器を前提とし、
　上記筐体に内蔵されるアンテナ基板と、
　上記アンテナエレメントが設けられたアンテナ部材と、
　上記アンテナ基板又は上記アンテナ部材に設けられ、上記アンテナエレメントと上記アンテナ基板とを電気的に接続するアンテナ給電バネとを備え、
　上記アンテナ給電バネを上記アンテナエレメント又は上記アンテナ基板に当接させて上記アンテナ部材をアンテナ基板に固定させた状態で、上記アンテナ基板が上記筐体の周縁に形成されたアンダーカット部に挿入されている。 Specifically, in the present invention, on the premise of an electronic device having an antenna element inside the housing,
An antenna substrate built in the housing;
An antenna member provided with the antenna element;
An antenna feeding spring provided on the antenna substrate or the antenna member and electrically connecting the antenna element and the antenna substrate;
The antenna substrate is inserted into an undercut formed on the peripheral edge of the housing in a state where the antenna feeding spring is brought into contact with the antenna element or the antenna substrate and the antenna member is fixed to the antenna substrate. Yes.
　上記の構成によると、アンテナ部材がアンテナ基板に固定された状態で、このアンテナ基板がアンダーカット部に挿入されるので、アンテナ給電バネが損傷することはない。ここで、アンダーカット部は、例えば、筐体の成形時に型開き方向と異なる方向にスライドするスライド型を設けて成形する必要のある部分をいう。 According to the above configuration, since the antenna substrate is inserted into the undercut portion while the antenna member is fixed to the antenna substrate, the antenna feeding spring is not damaged. Here, an undercut part means the part which needs to be shape | molded by providing the slide type | mold which slides in a direction different from a mold opening direction at the time of shaping | molding of a housing | casing, for example.
　以上説明したように、本発明によれば、筐体にアンテナ部を組込む際に、アンテナ基板側又はアンテナ部材側のアンテナ給電バネに対して横や斜め方向からの力が加わらないため、アンテナ給電バネを変形させることなく、アンダーカット部にアンテナ基板を組込むことができる。これにより、周縁にアンダーカット部を有する筐体であっても、アンテナエレメントを筺体の最外周部付近に配置することができるので、通信性能を格段に向上させることができる。 As described above, according to the present invention, when the antenna unit is assembled in the housing, the antenna feeding power is not applied to the antenna feeding spring on the antenna substrate side or the antenna member side. The antenna substrate can be incorporated into the undercut portion without deforming the spring. Thereby, even if it is a housing | casing which has an undercut part in a periphery, since an antenna element can be arrange | positioned in the outermost periphery part vicinity of a housing, communication performance can be improved significantly.

　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１～図４は本発明の実施形態の電子機器としてのスマートフォン１を示し、このスマートフォン１は、例えば、正面側に液晶ディスプレイ、有機ＥＬディスプレイなどの表示部２が設けられる矩形板状の筐体３を備えている。筐体３は、例えば、ステンレス鋼板等よりなる板金部３ｄがインサート成形された１つの樹脂成形品よりなり、背面側に枠状の貼付部３ａを有し、この貼付部３ａに板状の外観パネル４が貼り付けられている。貼付部３ａを設けることで、筐体３の少なくとも下端側にアンダーカット部３ｂが形成されている。なお、筐体３の左右側面及び下面は、Ｕ字状の装飾カバー５で覆われている。 1 to 4 show a smartphone 1 as an electronic apparatus according to an embodiment of the present invention. The smartphone 1 has a rectangular plate-like housing in which a display unit 2 such as a liquid crystal display or an organic EL display is provided on the front side. The body 3 is provided. The housing 3 is made of one resin molded product in which a sheet metal part 3d made of, for example, a stainless steel plate is insert-molded, and has a frame-like sticking part 3a on the back side, and the sticking part 3a has a plate-like appearance. Panel 4 is pasted. By providing the affixing portion 3 a, an undercut portion 3 b is formed on at least the lower end side of the housing 3. The left and right side surfaces and the lower surface of the housing 3 are covered with a U-shaped decorative cover 5.
　筐体３の背面側と外観パネル４との間には、スマートフォン１の全体を制御するメイン基板６が設けられ、その下側にアンテナ基板７が接続されている。詳しくは後述するが、アンテナ基板７の背面側には、アンテナ部材８が固定されている。 A main board 6 that controls the entire smartphone 1 is provided between the back side of the housing 3 and the exterior panel 4, and an antenna board 7 is connected to the lower side thereof. As will be described in detail later, an antenna member 8 is fixed on the back side of the antenna substrate 7.
　例えば、アンテナ基板７とメイン基板６との間に矩形板状の充電池９が収容されており、メイン基板６の背面は、サブアンテナ組品１０で覆われている。 For example, a rectangular plate-shaped rechargeable battery 9 is accommodated between the antenna substrate 7 and the main substrate 6, and the back surface of the main substrate 6 is covered with the sub antenna assembly 10.
　図６Ａ及び図６Ｂに示すように、アンテナ部材８は、樹脂成形品よりなり、表面に複数のアンテナエレメント８ａ（ハッチングで示す）が印刷やメッキ等で形成されている。なお、アンテナ部材８は、樹脂成形品に金属製のアンテナエレメント８ａを嵌め込んだものでもよいし、金属部品からなり、それ自体がアンテナエレメント８ａを構成するものでもよい。 As shown in FIGS. 6A and 6B, the antenna member 8 is made of a resin molded product, and a plurality of antenna elements 8a (shown by hatching) are formed on the surface by printing, plating, or the like. The antenna member 8 may be one in which a metal antenna element 8a is fitted into a resin molded product, or may be a metal part that itself constitutes the antenna element 8a.
　アンテナ基板７には、アンテナエレメント８ａに対して金属バネ部分が圧接して電気的に接続するアンテナ給電バネ１１が１又は複数（例えば３つ）設けられている。この個数は、アンテナエレメント８ａの個数に合わせて設ければよい。アンテナ基板７は、樹脂成形品等よりなるアンテナホルダ１２に嵌め込まれている。アンテナ基板７は、薄型化などのために、例えば０．２～０．３ｍｍ程度の薄いプリント基板よりなり、それ自体の強度は限られている。なお、アンテナ基板７をフレキシブル基板で構成してもよい。図４に示すように、アンテナ基板７には、例えば、スピーカ１３も設けられている。 The antenna substrate 7 is provided with one or a plurality (for example, three) of antenna feeding springs 11 in which a metal spring portion is pressed against and electrically connected to the antenna element 8a. This number may be provided in accordance with the number of antenna elements 8a. The antenna substrate 7 is fitted into an antenna holder 12 made of a resin molded product or the like. The antenna substrate 7 is made of a thin printed circuit board having a thickness of, for example, about 0.2 to 0.3 mm in order to reduce the thickness, and its strength is limited. In addition, you may comprise the antenna board | substrate 7 with a flexible substrate. As shown in FIG. 4, for example, the speaker 13 is also provided on the antenna substrate 7.
　図５Ａ及び図５Ｂにユニット化されたアンテナユニット２０を示すように、アンテナ部材８は、複数の係止爪８ｂを有し、アンテナ部材８は、アンテナ基板７が嵌合されたアンテナホルダ１２に垂直に近付けられ、図５Ａに示すように、これらの係止爪８ｂがアンテナホルダ１２に係止されるようになっている。そして、図１に示すように、アンテナ給電バネ１１がアンテナエレメント８ａに当接した状態で、アンテナ部材８がアンテナホルダ１２によりアンテナ基板７に固定されている。 5A and 5B, the antenna member 8 has a plurality of locking claws 8b, and the antenna member 8 is attached to the antenna holder 12 to which the antenna substrate 7 is fitted. These locking claws 8b are locked to the antenna holder 12 as shown in FIG. 5A. As shown in FIG. 1, the antenna member 8 is fixed to the antenna substrate 7 by the antenna holder 12 in a state where the antenna feeding spring 11 is in contact with the antenna element 8 a.
　そして、本実施形態では、スピーカ１３のスピーカ給電基板（図示せず）が設けられた樹脂成形品等よりなるアンテナカバー１４がアンテナ部材８を覆うようにしてアンテナホルダ１２に固定されている。 In this embodiment, an antenna cover 14 made of a resin molded product or the like provided with a speaker power supply board (not shown) of the speaker 13 is fixed to the antenna holder 12 so as to cover the antenna member 8.
　このように、アンテナ基板７は、アンテナホルダ１２及びアンテナカバー１４でアンテナ部材８を固定した状態で、筐体３の周縁に形成されたアンダーカット部３ｂに挿入されるようになっている。その挿入後に図３に示すように、アンテナカバー１４に設けたボルト挿通孔１４ａ及びアンテナホルダ１２に設けたボルト挿通孔１２ａにボルト５０を挿通して筐体３に共締めされるようになっている。これにより、アンテナ基板７に設けたグランド接点１５が筐体３の板金部３ｄに導通されている。なお、このアンテナカバー１４は、アンテナユニット２０に固定せず、アンテナユニット２０の挿入後、取り付けてもよい。また、このアンテナカバー１４は、なくてもよく、アンテナホルダ１２に設けたボルト挿通孔１２ａにボルト５０を挿通して筐体３に固定するようにしてもよい。 As described above, the antenna substrate 7 is inserted into the undercut portion 3 b formed on the periphery of the housing 3 in a state where the antenna member 8 is fixed by the antenna holder 12 and the antenna cover 14. After the insertion, as shown in FIG. 3, the bolt 50 is inserted into the bolt insertion hole 14 a provided in the antenna cover 14 and the bolt insertion hole 12 a provided in the antenna holder 12 to be fastened together with the housing 3. Yes. As a result, the ground contact 15 provided on the antenna substrate 7 is electrically connected to the sheet metal portion 3 d of the housing 3. The antenna cover 14 may not be fixed to the antenna unit 20 but may be attached after the antenna unit 20 is inserted. The antenna cover 14 may be omitted, and the bolt 50 may be inserted into the bolt insertion hole 12 a provided in the antenna holder 12 and fixed to the housing 3.
　そして、筐体３の貼付部３ａの反対側の面（正面側の面）は、図１に示すように、背面側に向かって傾斜した傾斜面３ｃが形成され、アンテナ基板７の挿入方向に向かって狭まっている。このため、図１に示す傾斜面３ｃの角度αは、９０度よりも小さくなっている（α＜９０°）。 As shown in FIG. 1, an inclined surface 3 c inclined toward the back side is formed on the opposite surface (front surface) of the sticking portion 3 a of the housing 3, and the antenna substrate 7 is inserted in the insertion direction. It is narrowing towards you. Therefore, the angle α of the inclined surface 3c shown in FIG. 1 is smaller than 90 degrees (α <90 °).
　このように本実施形態では、アンテナ基板７がアンテナホルダ１２に嵌め込まれ、アンテナ部材８から延びる係止爪８ｂが、アンテナホルダ１２に係止することにより、アンテナ給電バネ１１がアンテナエレメント８ａに圧接している。 As described above, in the present embodiment, the antenna substrate 7 is fitted into the antenna holder 12, and the locking claws 8b extending from the antenna member 8 are locked to the antenna holder 12, so that the antenna feeding spring 11 is pressed against the antenna element 8a. is doing.
　アンテナ部材８の組付時には、アンテナ部材８をアンテナ基板７に対して垂直に近付けながら固定することができるので、アンテナ給電バネ１１が損傷しにくい。 When the antenna member 8 is assembled, the antenna member 8 can be fixed while being close to the antenna substrate 7 perpendicularly, so that the antenna feeding spring 11 is not easily damaged.
