　すなわち、本発明に係る導電パターン形成筐体は、絶縁体からなる筐体と、該筐体の表面上に形成されている導電パターンとを備えており、該筐体には、該筐体を貫通し、連続する該導電パターンの互いに異なる位置に電気的に接続する導電部材が２つ以上設けられていることを特徴としている。 That is, a conductive pattern forming casing according to the present invention includes a casing made of an insulator and a conductive pattern formed on the surface of the casing. The casing includes the casing. Two or more conductive members that penetrate and are electrically connected to different positions of the continuous conductive pattern are provided.
　上記の構成によれば、連続する導電パターン上の一つの位置と、他の位置とに対して、異なる導電部材を介して同時に通電することができるため、当該一つの位置と、他の位置との間に断線等が生じていないかを容易に検査することができる。特に、導電部材が筐体を貫通するように設けられているため、導電パターンが形成されている領域とは異なる位置から通電することができる。これにより、例え、導電パターンの表面に通電するのが困難である場合であっても、容易に断線等をチェックすることができる導電パターン形成筐体を提供することができる。 According to said structure, since it can energize simultaneously through a different electrically-conductive member with respect to one position on a continuous conductive pattern, and another position, the one position and other positions It is possible to easily inspect whether or not there is a disconnection or the like between the two. In particular, since the conductive member is provided so as to penetrate the housing, it is possible to energize from a position different from the region where the conductive pattern is formed. Thereby, even if it is difficult to energize the surface of the conductive pattern, it is possible to provide a conductive pattern forming housing that can easily check for disconnection or the like.
　また、導電部材を介して通電を行った際、当該導電部材と導電パターンとの間の接続状態によって、通電状態が変化するため、導電部材と導電パターンとの間の接続状態についても容易にチェックすることができる。 In addition, when energization is performed through a conductive member, the energization state changes depending on the connection state between the conductive member and the conductive pattern, so the connection state between the conductive member and the conductive pattern can be easily checked. can do.
　すなわち、他の観点からみれば、導電部材と導電パターンとの間の接続状態を、直接導電パターンに通電することなく、導電部材を介した導通検査のみでチェックすることができる導電パターン形成筐体を提供することができる。 That is, from another point of view, the conductive pattern forming housing can check the connection state between the conductive member and the conductive pattern only by conducting a continuity test through the conductive member without directly passing the conductive pattern. Can be provided.
　本発明によれば、表面上に導電パターンが形成された筐体において、容易に導電パターンの断線をチェックすることができる。 According to the present invention, it is possible to easily check the disconnection of the conductive pattern in the case where the conductive pattern is formed on the surface.

　〔実施形態１〕
　以下、図１～７を参照して本発明の一実施形態（実施形態１）について説明する。 Embodiment 1
Hereinafter, an embodiment (Embodiment 1) of the present invention will be described with reference to FIGS.
　（導電パターン形成筐体）
　図１は、本実施形態に係る導電パターン形成筐体１０の構成を概略的に示す模式図であり、（ａ）は、導電パターン形成筐体１０の表面を示し、（ｂ）は、導電パターン形成筐体１０の裏面を示す。また、図２は、図１の（ａ）のＡで示す部分の側方断面図である。 (Conductive pattern forming housing)
FIG. 1 is a schematic diagram schematically showing the configuration of a conductive pattern forming housing 10 according to the present embodiment, where (a) shows the surface of the conductive pattern forming housing 10 and (b) shows a conductive pattern. The back surface of the forming housing 10 is shown. FIG. 2 is a side sectional view of a portion indicated by A in FIG.
　本明細書において、導電パターン形成筐体とは、表面上に導電パターンが形成されている筐体を指す。このような導電パターン形成筐体は、電子装置に組み込むことができ、電子装置に対して、アンテナエレメント、信号伝送経路、電力伝送経路等を提供する電子部品として利用可能である。 In this specification, the conductive pattern forming casing refers to a casing in which a conductive pattern is formed on the surface. Such a conductive pattern forming housing can be incorporated in an electronic device and can be used as an electronic component that provides the electronic device with an antenna element, a signal transmission path, a power transmission path, and the like.
　本実施形態に係る導電パターン形成筐体１０は、筐体１、導電パターン２、保護層３、導電部材４および導電部材５を備えている。 A conductive pattern forming housing 10 according to the present embodiment includes a housing 1, a conductive pattern 2, a protective layer 3, a conductive member 4, and a conductive member 5.
　筐体１は、絶縁体からなり、例えば、電子装置の筐体を構成している。電子装置の筐体とは、電子装置が備える電子部品を格納する部材を指す。本実施形態では、筐体１は板状の形状を有しているがこれに限定されず、構成する電子装置に応じた形状を有していればよい。 The housing 1 is made of an insulator and constitutes, for example, a housing of an electronic device. The casing of the electronic device refers to a member that stores an electronic component included in the electronic device. In the present embodiment, the housing 1 has a plate shape, but is not limited to this, and it is only necessary to have a shape corresponding to the electronic device to be configured.
　（導電パターン）
　導電パターン２は、筐体１の表面上に形成されている導電体である。導電パターン２は、例えば、導電ペーストが筐体１の表面上に塗布されてなる導電膜であってもよいし、フレキシブルプリント基板等の可撓性を有する導電膜であってもよいし、メッキ等によって構成されていてもよい。後述するように、本実施形態において、導電パターン２は、アンテナエレメントとして使用されるが、本発明はこれに限定されず、電子装置内において、導電パターン２が形成された領域に配置された部材を電気的に接続するために用いてもよい。 (Conductive pattern)
The conductive pattern 2 is a conductor formed on the surface of the housing 1. The conductive pattern 2 may be, for example, a conductive film obtained by applying a conductive paste on the surface of the housing 1, a flexible conductive film such as a flexible printed circuit board, or plating. Or the like. As will be described later, in the present embodiment, the conductive pattern 2 is used as an antenna element. However, the present invention is not limited to this, and a member arranged in a region where the conductive pattern 2 is formed in the electronic device. May be used for electrical connection.
　導電パターン２を、導電ペーストが筐体１の表面上に塗布されてなる導電膜として構成する場合、導電ペーストとしては、粘性を有する導電体材料であり、少なくとも、金属粉および溶剤からなるものであり、好ましくは、金属粉、バインダー樹脂および溶剤からなるものを用いることができる。導電ペーストが塗布されてなる導電膜は、例えば、乾燥により溶剤が除去されていてもよく、溶剤が一部残留していてもよい。導電ペーストの塗布方法としては種々の方法を採ることができるが、好適には、筐体１および導電部材４の形状に適合するように、可撓性を有する印刷版を用いた印刷（例えば、フレキソ印刷、オフセット印刷、シルク印刷、パッド印刷等）により塗布することが好ましい。 When the conductive pattern 2 is configured as a conductive film in which a conductive paste is applied on the surface of the housing 1, the conductive paste is a conductive material having viscosity, and is composed of at least metal powder and a solvent. Yes, preferably, a metal powder, a binder resin and a solvent can be used. In the conductive film formed by applying the conductive paste, for example, the solvent may be removed by drying, or a part of the solvent may remain. Various methods can be adopted as a method for applying the conductive paste, but preferably, printing using a flexible printing plate so as to conform to the shapes of the casing 1 and the conductive member 4 (for example, It is preferable to apply by flexographic printing, offset printing, silk printing, pad printing and the like.
　導電パターン２を、導電ペーストを塗布することにより形成することにより、導電パターンを薄くすることが可能であり、また、容易に曲面的な形状とすることができるので、設計の自由度をより向上させることができる。 By forming the conductive pattern 2 by applying a conductive paste, it is possible to make the conductive pattern thin, and it is possible to easily form a curved shape, so that the degree of freedom in design is further improved. Can be made.
　また、可撓性を有する印刷版を用いた印刷（フレキソ印刷、オフセット印刷、シルク印刷、パッド印刷等）により、導電ペーストを塗布することにより、筐体等の形状に合わせて首尾よく導電パターンの印刷を行うことができ、構造物の大量生産等にも寄与することができる。 In addition, by applying a conductive paste by printing (flexo printing, offset printing, silk printing, pad printing, etc.) using a flexible printing plate, the conductive pattern can be successfully formed according to the shape of the housing and the like. Printing can be performed, which can contribute to mass production of structures.
　なお、導電パターン２を、フレキシブルプリント基板のような可撓性を有する導電膜から構成した場合であっても、導電パターン２を、自由な形状に固定することができるので、設計の自由度を向上させることができる。 Even when the conductive pattern 2 is made of a flexible conductive film such as a flexible printed circuit board, the conductive pattern 2 can be fixed in a free shape. Can be improved.
　すなわち、導電パターン２を、フレキシブルプリント基板等の可撓性を有する導電膜、または、導電ペーストが塗布されてなる導電膜等の、それ自体では保形性を有さない（自己保形性を有さない）導電膜によって構成することにより、設計の自由度を向上させることができる。 That is, the conductive pattern 2 itself does not have shape-retaining properties such as a flexible conductive film such as a flexible printed circuit board or a conductive film coated with a conductive paste (self-shaped retaining property). The degree of freedom in design can be improved by using a conductive film that is not provided.
　また、メッキによって導電パターン２を構成してもよい。 Further, the conductive pattern 2 may be formed by plating.
　（保護層）
　保護層３は、導電パターン２の表面（導電パターン２の筐体１とは反対側の面）を被覆する絶縁体材料である。保護層３を設けることによって、導電パターン２が損傷（断線、剥離等）することを防ぐことができるとともに、導電パターン２を目隠しすることができる。また、保護層３によって、導電パターン２の表面（導電パターン２の筐体１とは反対側の面）は、外部から絶縁される。但し、本発明において、保護層３は必須の構成要素ではなく、保護層３を設けなくともよい。 (Protective layer)
The protective layer 3 is an insulating material that covers the surface of the conductive pattern 2 (the surface of the conductive pattern 2 opposite to the casing 1). By providing the protective layer 3, the conductive pattern 2 can be prevented from being damaged (disconnection, peeling, etc.), and the conductive pattern 2 can be blinded. Further, the surface of the conductive pattern 2 (the surface of the conductive pattern 2 opposite to the casing 1) is insulated from the outside by the protective layer 3. However, in the present invention, the protective layer 3 is not an essential component, and the protective layer 3 may not be provided.
　本実施形態において、保護層３は、アンテナの性能に影響を与えない材質のものであり、導電パターン２を保護するだけの強度を有するものであればよい。ここでアンテナの性能に影響を与えないとは、保護層３の有無でアンテナの性能が著しく劣化しないものである。 In the present embodiment, the protective layer 3 is made of a material that does not affect the performance of the antenna, and may have any strength that protects the conductive pattern 2. Here, “not affecting the performance of the antenna” means that the performance of the antenna is not significantly deteriorated by the presence or absence of the protective layer 3.
　保護層３は、貼り付け、塗布、噴き付けなどで導電パターン２上に設けられるものであればよく、例えば、コーティング剤（例えば、樹脂溶液）によって形成されるものを好適に用いることができる。また、このコーティング剤の塗布は、筐体１の塗装を兼ねていてもよい。また、保護層３はシート状のものであって、シールのように貼り付けたり熱や圧力で圧着できるものであってもよい。 The protective layer 3 only needs to be provided on the conductive pattern 2 by pasting, coating, spraying, or the like, and for example, a layer formed of a coating agent (for example, a resin solution) can be suitably used. The coating agent may also be applied to the housing 1. Moreover, the protective layer 3 is a sheet-like thing, and may be affixed like a seal | sticker or can be crimped | bonded by a heat | fever or a pressure.
　（導電部材）
　本実施形態に係る導電パターン形成筐体１０では、筐体１には、筐体１を貫通し、連続する導電パターン２の互いに異なる位置に電気的に接続する導電部材が２つ以上設けられている（導電部材４および５）。 (Conductive member)
In the conductive pattern forming housing 10 according to the present embodiment, the housing 1 is provided with two or more conductive members that penetrate the housing 1 and are electrically connected to different positions of the continuous conductive pattern 2. (Conductive members 4 and 5).
　導電部材４および５は、例えば、金属等の導電体からなる部材である。図２に示すように、導電部材４の形状は、例えば、柱状であり得、好ましくは、ピン形状であり得る。これにより、筐体１を貫通する導電部材４を好適に構成することができる。なお、円柱状に限られず、角柱状であってもよい。また、その太さも均一でなくてもよい。また、図２に示すように、筐体１から突出していてもよいし、筐体１から凹んだ状態であってもよい。導電部材５の形状も同様である。 Conductive members 4 and 5 are members made of a conductor such as metal, for example. As shown in FIG. 2, the shape of the conductive member 4 can be, for example, a columnar shape, and preferably a pin shape. Thereby, the electrically-conductive member 4 which penetrates the housing | casing 1 can be comprised suitably. The shape is not limited to a cylindrical shape, and may be a prism shape. Moreover, the thickness may not be uniform. In addition, as shown in FIG. 2, it may protrude from the housing 1 or may be in a state of being recessed from the housing 1. The shape of the conductive member 5 is also the same.
　そして、導電部材４の導電パターン２側の面４ａは、導電パターン２と接触しており、導電部材４と導電パターン２とは電気的に接続されている。また、導電部材４の導電パターン２とは反対側の面４ｂは、導電パターン２に通電するための電極となる。導電部材５も同様である。 The surface 4a on the conductive pattern 2 side of the conductive member 4 is in contact with the conductive pattern 2, and the conductive member 4 and the conductive pattern 2 are electrically connected. Further, the surface 4 b of the conductive member 4 opposite to the conductive pattern 2 serves as an electrode for energizing the conductive pattern 2. The same applies to the conductive member 5.
　また、導電部材４および５は、筐体１にインサート成形されていてもよい。これにより、筐体１に対して導電部材４および５を容易に貫通させることができる他、防水性を向上させることもできる。また、導電部材４および５が筐体１にインサート成形されている状態で、導電パターン２を印刷法等により形成することにより、導電部材４および５と導電パターン２との電気的な接続を良好なものにすることができる。 Further, the conductive members 4 and 5 may be insert-molded in the housing 1. Thereby, the conductive members 4 and 5 can be easily penetrated with respect to the housing 1, and the waterproof property can be improved. Further, by forming the conductive pattern 2 by a printing method or the like in a state where the conductive members 4 and 5 are insert-molded in the housing 1, the electrical connection between the conductive members 4 and 5 and the conductive pattern 2 is good. Can be made.
　そして、図１に示すように、導電部材４および５は、それぞれ、連続する導電パターン２の互いに異なる位置に電気的に接続するようになっている。また、導電部材４および５は、導電パターン２が設けられている領域から筐体１上の保護層３によって被覆されていない領域まで貫通している。したがって、導電部材４および５を介して通電することによって、導電パターン２の複数箇所に対して、導電パターンが設けられている位置とは異なる位置、特に、保護層３が設けられていない領域から容易に通電を行うことができる。 As shown in FIG. 1, the conductive members 4 and 5 are electrically connected to different positions of the continuous conductive pattern 2, respectively. Further, the conductive members 4 and 5 penetrate from a region where the conductive pattern 2 is provided to a region which is not covered with the protective layer 3 on the housing 1. Therefore, by energizing through the conductive members 4 and 5, a position different from the position where the conductive pattern is provided with respect to a plurality of locations of the conductive pattern 2, particularly from a region where the protective layer 3 is not provided. Energization can be performed easily.
　（導通検査方法）
　そして、本実施形態に係る導電パターン形成筐体１０に対して、任意の２つの導電部材間に電流が流れるか否かを検査する検査工程を実行することによって、容易に、導電パターン２の断線をチェックすることができる。 (Continuity test method)
Then, the conductive pattern 2 is easily disconnected by performing an inspection process for inspecting whether a current flows between any two conductive members on the conductive pattern forming housing 10 according to the present embodiment. Can be checked.
　すなわち、導電部材４および５に対して、公知の導通テスター等を用いて、筐体１の裏面側から通電して導電部材４および５の間に電流が流れるか否かを検査することにより、導電パターン２における導電部材４および５の間に断線が生じているか否かをチェックすることができる。また、このとき、導電部材４および５と導電パターン２との間の導通性も同時にチェックすることができる。 That is, by inspecting whether the current flows between the conductive members 4 and 5 by energizing the conductive members 4 and 5 from the back side of the housing 1 using a known continuity tester or the like, It can be checked whether or not a disconnection has occurred between the conductive members 4 and 5 in the conductive pattern 2. At this time, the conductivity between the conductive members 4 and 5 and the conductive pattern 2 can be checked at the same time.
　本発明に係る導電部材がない場合、導電パターン２の断線等をチェックするためには、例えば、導電パターン２の表面に対して導通テスター等の端子を当てる必要があり、導電パターン２を損傷するおそれがある。また、保護層３が形成された後は、断線等をチェックすることができない。これに対し、本発明に係る導電部材を設けた場合には、導電パターン２の表面に対して導通テスター等の端子を当てる必要がなく、保護層３が形成された後でも断線等をチェックすることができる。特に、本実施形態のように、導電部材が何れも筐体１の裏面に貫通している場合には、筐体１の裏面からのみ通電させればよいので、作業性が向上する。 When there is no conductive member according to the present invention, in order to check the disconnection of the conductive pattern 2, for example, it is necessary to apply a terminal such as a continuity tester to the surface of the conductive pattern 2, and the conductive pattern 2 is damaged. There is a fear. Moreover, after the protective layer 3 is formed, disconnection or the like cannot be checked. On the other hand, when the conductive member according to the present invention is provided, it is not necessary to apply a terminal such as a continuity tester to the surface of the conductive pattern 2, and the disconnection or the like is checked even after the protective layer 3 is formed. be able to. In particular, when all the conductive members penetrate the back surface of the housing 1 as in this embodiment, it is only necessary to energize only from the back surface of the housing 1, so that workability is improved.
　検査工程は、例えば、公知の導通テスターを用いればよいが、図３に示すような導通検査治具９０を用いてもよい。導通検査治具９０は、当接面９１、端子部９２および９３ならびに検査回路９４を備えている。当接面９１は、導電パターン形成筐体１０に当接するための面であり、例えば、導電パターン形成筐体１０に嵌合するような形状を有していてもよい。端子部９２および９３は、それぞれ、導電部材４および５に対応するものであり、当接面９１が導電パターン形成筐体１０に当接したときに、端子部９２および９３は、それぞれ、導電部材４および５に接続するようになっている。そして、検査回路９４は、端子部９２および９３を介して導電部材４および５に電気的に接続して、導電部材４および５の間に電流が流れるか否かを判定する。このような導通検査治具９０を用いることにより、容易に検査工程を実行することができる。 In the inspection process, for example, a known continuity tester may be used, but a continuity inspection jig 90 as shown in FIG. 3 may be used. The continuity inspection jig 90 includes a contact surface 91, terminal portions 92 and 93, and an inspection circuit 94. The contact surface 91 is a surface for contacting the conductive pattern forming housing 10, and may have a shape that fits into the conductive pattern forming housing 10, for example. The terminal portions 92 and 93 correspond to the conductive members 4 and 5, respectively. When the contact surface 91 contacts the conductive pattern forming housing 10, the terminal portions 92 and 93 are respectively connected to the conductive members. 4 and 5 are connected. Then, the inspection circuit 94 is electrically connected to the conductive members 4 and 5 through the terminal portions 92 and 93 and determines whether or not a current flows between the conductive members 4 and 5. By using such a continuity inspection jig 90, the inspection process can be easily performed.
　なお，検査工程において、通電する導電部材は任意の２つを選ぶことができ、例えば、後述するような、他の回路またはグランドと接続する導電部材を選択してもよいし、他の回路またはグランドと接続しない導電部材を選択してもよい。 In the inspection step, any two conductive members to be energized can be selected. For example, a conductive member connected to another circuit or ground as described later may be selected, or another circuit or A conductive member that is not connected to the ground may be selected.
　（アンテナ装置）
　本実施形態において、導電パターン形成筐体１０は、アンテナ装置１００に組み込まれ、導電パターン２は、アンテナ装置１００のアンテナエレメントとして動作する。以下、アンテナ装置１００について説明する。 (Antenna device)
In the present embodiment, the conductive pattern forming housing 10 is incorporated in the antenna device 100, and the conductive pattern 2 operates as an antenna element of the antenna device 100. Hereinafter, the antenna device 100 will be described.
　図４は、アンテナ装置１００の構成を概略的に示すブロック図である。図５は、アンテナ装置１００の構成を概略的に示す斜視図である。なお、図５では、アンテナ装置１００の一部を切り開いて断面を示している。 FIG. 4 is a block diagram schematically showing the configuration of the antenna device 100. FIG. 5 is a perspective view schematically showing the configuration of the antenna device 100. In FIG. 5, a part of the antenna device 100 is cut open to show a cross section.
　アンテナ装置１００は、導電パターン形成筐体１０に加えて、接続部２０、無線回路３０および図示しないグランド４０を備えている。図４に示すように、導電パターン２は、導電部材４を介して無線回路３０に接続されている。より詳しくは、図５に示すように、導電部材４は、無線回路３０と電気的に接続している接続部２０と電気的に接続している。接続部２０は、例えば、導電体のバネ構造を有しており、導電部材４の面４ｂに導電体を押しつけることにより、導電部材４と電気的に接続する。また、導電部材５は、無線回路３０およびグランド４０の何れにも接続していない。すなわち、本実施形態において、導電部材５は、導通性のチェックのためのみに使用される。ただし、導電部材５はアンテナの一部となっているため、アンテナからの電波の放射には寄与する。 The antenna device 100 includes a connection unit 20, a radio circuit 30, and a ground 40 (not shown) in addition to the conductive pattern forming housing 10. As shown in FIG. 4, the conductive pattern 2 is connected to the wireless circuit 30 via the conductive member 4. More specifically, as shown in FIG. 5, the conductive member 4 is electrically connected to a connection portion 20 that is electrically connected to the radio circuit 30. The connecting portion 20 has, for example, a conductor spring structure, and is electrically connected to the conductive member 4 by pressing the conductor against the surface 4 b of the conductive member 4. Further, the conductive member 5 is not connected to either the radio circuit 30 or the ground 40. In other words, in the present embodiment, the conductive member 5 is used only for checking conductivity. However, since the conductive member 5 is a part of the antenna, it contributes to the emission of radio waves from the antenna.
　このようなアンテナ装置１００を製造する方法において、導電パターン形成筐体１０を、アンテナ装置１００に組み込む前に、導電パターン形成筐体１０に対して、上述した導通検査方法を実行することにより、アンテナエレメントの断線等のリスクが低い高品質なアンテナ装置を提供することができる。 In such a method of manufacturing the antenna device 100, before the conductive pattern forming housing 10 is incorporated in the antenna device 100, the above-described continuity inspection method is executed on the conductive pattern forming housing 10 to thereby provide an antenna. It is possible to provide a high-quality antenna device with a low risk of element disconnection or the like.
　（導電部材の変形例）
　以上では、導電パターン形成筐体１０が備える導電部材として、図２に示すようなピン形状の導電部材４および５を用いる場合について説明したが、導電パターン形成筐体１０が備える導電部材はこれに限定されない。 (Modification of conductive member)
In the above, the case where the pin-shaped conductive members 4 and 5 as shown in FIG. 2 are used as the conductive members included in the conductive pattern forming housing 10 has been described. However, the conductive members included in the conductive pattern forming housing 10 are not limited thereto. It is not limited.
　例えば、図６の（ａ）および（ｂ）に示すように、導電部材４（および５）は、フランジ部分４ｃを備え、「工」型、「王」型の断面を有していてもよい。これにより、防水性をより向上させることができる。 For example, as shown in FIGS. 6A and 6B, the conductive member 4 (and 5) includes a flange portion 4 c and may have a “work” type or “king” type cross section. . Thereby, waterproofness can be improved more.
　また、図６の（ｃ）に示すように、導電部材４（および５）は、板金によって構成されていてもよい。 Further, as shown in FIG. 6C, the conductive member 4 (and 5) may be made of sheet metal.
