Description

【0001】
【発明の属する技術分野】
本発明は、基板上に実装される電子部品をシールドするシールド部材の装着構造に関し、特には、シールド部材を構成する金属ケースとカバーの装着構造に関する。
【0002】
【従来の技術】
従来、基板上に実装される高周波機器等の電子部品をシールドするシールド部材として、例えば、図7に示すように、一体の金属部材が箱の形に折り曲げられて箱形状に形成されたものが提供されている(特許文献1参照)。
上記箱形に形成されたシールド部材Cは、図示するように、その上面及び側面に多数の孔が形成されており、これら複数の孔を通過する赤外線エネルギーにより、シールド部材内部に配置された電子部品31を基板30にリフロー半田付けする構成となっている。
【0003】
しかし、上記のように構成されたシールド部材Cは、上記複数の孔を通過する赤外線エネルギーにより電子部品31をリフロー半田付けする構成であるため、半田付けする際に必要なエネルギーが十分ではない場合があり、電子部品31を基板30上に確実に実装することができないおそれがあった。
【0004】
また、上記シールド部材Cとは別に、図6に示すシールド部材Bが提供されている。
このシールド部材Bは、内部に電子部品を収納する一面側が開口した開口部51を備える金属ケース50と、該金属ケース50の開口部51を閉じるカバー60とから構成されている(特許文献2参照)。
【0005】
上記シールド部材Bによれば、金属ケース50は開口部51を備えているため、金属ケース50内部に収納された電子部品を基板(いずれも図示せず)にリフロー半田付けする際に、開口部51から十分な赤外線エネルギーの供給を得ることができ、金属ケース50内部に収納された電子部品を基板上に確実に実装することができる。
【0006】

【特許文献2】
実公平1−26147号公報
【0007】
【発明が解決しようとする課題】
しかしながら、上記従来のシールド部材Bにおいては、以下の問題があった。すなわち、シールド部材Bの金属ケース50を基板に取り付ける際に、手作業で半田付けを行うと、シールド部材の基板上での取り付け位置にバラツキが生じるという問題を有していた。
【0008】
また、上記取り付け位置のバラツキを防止するために、シールド部材Bを基板に自動実装する構成とすると、金属ケース50の開口部51に設けられた自動実装用の被吸着部材52が必要となり、金属ケース50内部に収納された電子部品のメンテナンスを行う際に邪魔になるおそれがあった。
【0009】
すなわち、図6に示すように、上記被吸着部材52は、略十字形状に形成され、金属ケース50の開口部51の開口面にわたって形成されており、金属ケース50内部に収納された電子部品を金属ケース50から取り出すことができず、メンテナンス時の作業効率が悪いという問題を有していた。
【0010】
さらにまた、シールド部材Bを構成する金属ケース50とカバー60は、半田付け等されることにより互いに接合されているため、金属ケース50内に収納された電子部品をメンテナンスする際にカバー60の取り外しが困難であり、また、金属ケース50とカバー60を接合するために、半田付け等する作業が必要となる。
【0011】
本発明は、上記問題点を解決するためになされたものであり、シールド部材の基板上での取り付け位置のバラツキを防止することができるとともに、金属ケースとカバーとの脱着の作業を容易化することができ、さらに、金属ケース内部に収納された電子部品のメンテナンスを容易に行うことができるシールド部材の装着構造を提供することを目的とする。
【0012】
【課題を解決するための手段】
上記目的を達成するために、請求項1の発明は、
電子部品を内部に収納した状態で基板上に配設され、一面側が開口した開口部を有する収納枠と、該収納枠の開口部を閉じるカバーと、からなるシールド部材の装着構造において、

上記収納枠は、自動実装用吸着ノズルに吸着される被吸着部材を有してなり、
上記被吸着部材は、吸着ノズルに吸着されるノズル吸着部と、該ノズル吸着部を収納枠に支持する破断可能な支持部とを備え、
上記破断可能な支持部を破断することにより、ノズル吸着部を除去し得るように構成され、
上記被吸着部材の支持部と収納枠の破断可能な接合地点は、収納枠の側壁の上端よりも下方に位置することを特徴とする。
【0013】
請求項2の発明は、請求項1に記載のシールド部材の装着構造において、
装着構造は、収納枠の側壁に形成された被係止凹部と、カバー内側の前記被係止凹部に対応する位置に形成され且つ弾性を備えた係止凸部とからなり、
前記係止凸部が弾性付勢力によって収納枠の被係止凹部内に嵌め込まれた状態で、カバーが収納枠に装着されるように構成されたことを特徴とする。
【0016】
【作用】
請求項1の発明によれば、カバーを収納枠に着脱可能な装着構造により、シールド部材のカバーと収納枠とを導通させた状態で、カバーが収納枠に着脱される。
また、被吸着部材の破断可能な支持部が破断されることにより、ノズル吸着部が除去される。また、被吸着部材の支持部と収納枠の破断可能な接合地点が収納枠の側壁の上端よりも下方に位置する。
求項2の発明によれば、装着構造の弾性を備えた係止凸部が弾性付勢力によって収納枠の被係止凹部内に嵌め込まれた状態で、カバーが収納枠に装着される。
【0018】
【発明の実施の形態】
以下に、本発明にかかるシールド部材の装着構造の一実施形態について図面を用いて詳細に説明する。
図1は、本発明のシールド部材の装着構造に用いられるシールド部材を示す斜視図である。
同図に示すように、このシールド部材Aは、内部に電子部品を収納する金属製の収納枠10と、この収納枠10の開口部を閉じるカバー20とを備えて構成されている。
【0019】
図2は、上記収納枠10を示す図である。同図(a)は収納枠10の平面図、同図(b)は収納枠10の裏面図、同図(c)は収納枠10の側面図、同図(d)は同図(a)のa−a´の断面を示す断面図である。
【0020】
収納枠10は、図1に示すように、電子部品31を内部に収納した状態で基板30上に配設されるもので、本実施形態においては、図2(a)に示すように、開口部10aを備えた略矩形の枠形状に形成されている。
この収納枠10の側壁11には、図2(c)に示すように、一対の被係止凹部11a,11aが形成されており、本実施形態において、この被係止凹部は側壁11を貫通する一対の丸孔により構成されている。
【0021】
また、上記被係止凹部11a,11aが形成された側壁11に対向する収納枠10の側壁12(図1参照)には、被係止凹部11a,11aに対応する位置に一対の被係止凹部12a,12aが形成されている(図1参照)。
【0022】
ここで、上記収納枠10の開口部10aには、自動実装用の吸着ノズルにより吸着される被吸着部材13が設けられている。
この被吸着部材13は、図2(a)及び(b)に示すように、実際に自動実装用の吸着ノズルにより吸着されるノズル吸着部13aと、このノズル吸着部13aを収納枠10に支持する破断可能な支持部13bとを備えた薄板形状に形成されている。
【0023】
この被吸着部材13は、本実施形態においては、その中央部付近が略円形に形成されてノズル吸着部13aが構成されているとともに、その両端部付近がノズル吸着部13aよりも狭い幅を有する薄板状に形成されて支持部13bが構成されている。
そして、上記被吸着部材13の支持部13bの両端部が収納枠10の側壁11及び12に接合されることにより、ノズル吸着部13aが収納枠10に支持されている。
【0024】
ここで、上記被吸着部材13の支持部13bと収納枠10の側壁11,12の接合地点Xは、図2(a)及び(b)に示すように、支持部13bよりもさらに幅が狭く形成されており、支持部13bと収納枠10の側壁11,12の接触面積は非常に小さくなっている。
これにより、上記支持部13bが接合地点Xで破断可能な構成となっている。また、図2(d)に示すように、上記破断可能な接合地点Xは、収納枠10の側壁11,12の上端に対して一段低い位置に位置している。
【0025】
つぎに、図3を用いて、カバー20について説明する。同図(a)はカバー20の平面図、同図(b)はカバー20の裏面図、同図(c)はカバー20の側面図、同図(d)はカバー20の正面図をそれぞれ示している。
【0026】
カバー20は、図3(a)及び(b)に示すように、その前面側及び裏面側が開口した蓋形状に形成されており、前記収納枠10の開口部10aを閉じる寸法を有する略矩形状に形成されている。
このカバー20の側面21,22の内側で、前記収納枠10の側壁11,12にそれぞれ形成された一対の被係止凹部11a,11a及び12a,12aに対応する位置には、弾性を備えた一対の係止凸部21a,21a及び22a,22aが設けられている。
【0027】
上記各係止凸部21a及び22aは、本実施形態においては、図3(b)及び(c)に示すように、上述した収納枠10の被係止凹部11a,11a及び12a,12aに嵌め込み可能な寸法を有する半球状に形成されている。
また、これら係止凸部21a,21a及び22a,22aが設けられた各側面21、22の前面側、すなわち、カバー20の前面側の端部は、上述したように開口しているため、これら各側面21,22に形成された係止凸部21a,21a及び22a,22aはカバー20の外側方向に弾性を有する構成となっている。
【0028】
上記カバー20の各側面21,22の前面側には、図3(d)に示すように、カバー20を収納枠10から容易に取り外すために、突設片21b及び22bが各側面21,22よりも外側に開いた方向に突設されている。
【0029】
また、上記カバー20の上面、両側面及び背面には、図3(a)及び(b)に示すように、カバー20と収納枠10との半田付けポイントとなる切り欠き23a〜23dが4辺にそれぞれ形成されており、カバー20を収納枠10に装着した状態で、収納枠10の両側面及び背面に当接して凹部を形成し、半田付けするポイントが形成される。
【0030】
上記のように構成された収納枠10と、カバー20とを装着するには、まず、図1に示すように、基板30上に電子部品31を配置した状態で、電子部品31を内部に収納する位置にシールド部材Aの収納枠10を配置する。
ここで、上記収納枠10の基板30への配置は自動実装機(図示せず)により行われるが、具体的には、前記収納枠10の被吸着部材13のノズル吸着部13aを自動実装機の吸着ノズルで吸着して基板上の定められた位置に配置する。
【0031】
つぎに、上記のように内部に電子部品31を収納した状態で基板30上に配置された収納枠10を、電子部品31とともに基板30にリフロー半田付けする。このとき、収納枠10の開口部10aからリフロー半田付けに十分な赤外線エネルギーの供給を得ることができ、収納枠10内部に収納された電子部品31を基板30上に確実に実装することができる。
【0032】
そして、上記基板30上に取り付けられた収納枠10の開口部10aをカバー20で閉じることにより、基板30上に取り付けられた電子部品31をシールドする。以下、図4を用いて、カバー20を収納枠10に装着する際の動作について説明する。なお、図4は、収納枠10とカバー20との装着状態を示す図であり、同図(a)は収納枠10とカバー20との装着状態を示す平面図、同図(b)は装着状態を示す裏面図、同図(c)は装着状態を示す側面図、同図(d)は同図(a)のb−b´の断面を示す断面図である。
【0033】
まず、カバー20を収納枠10に装着するには、カバー20を収納枠10の開口部10aに被せる。
このとき、カバー20の側面21,22の内側に形成された係止凸部21a,21a及び22a,22aは、収納枠10の側壁11及び12に接触し、カバー20の各側面21,22が収納枠10の側壁11,12の外側に弾性変形する。
【0034】
そして、この状態で、さらにカバー20を下方に押し込めると、図4(a)〜(d)にそれぞれ示すように、カバー20に形成された係止凸部21a,21a及び22a,22aが、収納枠10の側壁11,12に形成された被係止凹部11a,11a及び12a,12a内に嵌め込まれて、カバー20が収納枠10に装着される。
これにより、収納枠10及びカバー20が接触導通し、収納枠10内部に収納された電子部品31は、収納枠10及びカバー20によりシールドされる。
【0035】
また、収納枠10からカバー20を取り外す際には、カバー20に突設された突設片21b,22bを収納枠10の外側に開く方向に押し広げことにより、カバー20の各側壁に形成された係止凸部21a,21a及び22a,22aと、収納枠10の被係止凹部11a,11a及び12a,12aの嵌合状態を解除する。
【0036】
このとき、上述したように、カバー20の各側面21及び22に形成された各被係止凸部21a,22aは、収納枠10の外側に開く方向に弾性を備えているため、上記嵌合状態を容易に解除することができる。
【0037】
以上のように、本発明のシールド部材Aの装着構造においては、収納枠10の被吸着部材13のノズル吸着部13aを自動実装用の吸着ノズルで吸着して基板上に配置する構成としているため、シールド部材Aの収納枠10の基板30上での配置位置のバラツキを無くすことができる。
【0038】
また、カバー20の弾性を備えた各係止凸部21a,22aが弾性付勢力によって収納枠10の各被係止凹部内11a,12aに嵌め込まれた状態で、カバー20が収納枠10に装着される構成であるため、収納枠10とカバー20との装着の作業を容易化することができる。
さらに、この装着時においては、半田付け等の作業が不必要となる。
【0039】
つぎに、上述したように収納枠10からカバー20を取り外した状態で、収納枠10内に収納された電子部品31をメンテナンスする作業について説明する。この電子部品31のメンテナンスは、収納枠10に支持されたノズル吸着部13aを除去して行う。
【0040】
ここで、上記ノズル吸着部13aを除去するには、被吸着部材13の支持部13bを破断することにより行うが、具体的には、ノズル吸着部13aを支持部13bを回転軸とした回転方向に回転させることにより、支持部13bを破断する。
【0041】
このとき、被吸着部材13の支持部13bと収納枠10の破断可能な接合地点Xには、ノズル吸着部13aの回転により生じる力が加えられ、この接合地点Xにおける支持部13bと収納枠10の側壁との接触面積は非常に小さいため、支持部13bは破断する。
そして、この支持部13bにより収納枠10に支持されていたノズル吸着部13aは除去される。
【0042】
この結果、収納枠10に接合された被吸着部材13を収納枠10から除去した状態で、収納枠10の開口部10aを介して内部の電子部品31のメンテナンスを行うことができ、これにより、作業者はメンテナンスに十分な作業スペースを確保することができるため、迅速な電子部品31の交換作業を行うことができ、作業効率の向上を図ることができる。
【0043】
また、上記ノズル吸着部13aが除去された後の収納枠10の接合地点Xには、上向きのバリが形成される可能性があるが、前述したように、被吸着部材13の支持部13bと収納枠10の破断可能な接合地点Xは、収納枠10の側壁11,12の上端より一段低い位置に形成されているため、図5に示すように、バリが収納枠10の側壁11,12の上端より上に飛び出すことを防ぐことができ、スムーズに収納枠10の開口部10aをカバー20で閉じることができる。
【0044】
以上のように、被吸着部材13を除去した状態で、電子部品31のメンテナンスが終了すると、再び収納枠10の開口部10aをカバー20で閉じることにより電子部品31のシールドを行うことができる。
【0045】
以上、本発明のシールド部材の装着構造の一実施形態について詳細に説明してきたが、本発明は上記実施の形態に限定されるものではない。
例えば、上記実施の形態においては、収納枠10とカバー20とは被係止凹部に係止凸部を嵌合することにより着脱可能に構成していたが、カバー20により収納枠10の開口部10aを閉じた状態で、カバー20に形成された切り欠き23a〜23dに半田付けを行うことにより、カバー20を閉じる構成とすることも可能である。
【0046】
また、収納枠10とカバー20の装着構造は、上述した実施形態の被係止凹部11a,12a及び係止凸部21a,22aに限定されるものではなく、カバー20を収納枠10に着脱可能に装着し得るものであれば、どのような構成であっても構わない。
例えば、上記装着構造の一例としては、収納枠に係止凸部を、カバーに係止凹部を備える構成とすることも可能である。
【0047】
【発明の効果】
請求項1の発明によれば、装着構造によりシールド部材のカバーと収納枠とを導通させた状態で、カバーを収納枠に着脱可能となる。
この結果、収納枠とカバーを半田付けする必要がなく、収納枠内に収納された電子部品を取り替える際にカバーの取り外しが容易になり、電子部品のメンテナンス時の作業性が上昇するという効果がある。
また、収納枠に備えられた被吸着部材のノズル吸着面が自動実装用吸引ノズルに吸着されるため、シールド部材の収納枠を基板上に自動実装することができ、基板上でのシールド部材の配置位置のバラツキを無くすことができる。
また、被吸着部材の支持部と収納枠の破断可能な接合地点は、ノズル吸着部の回転により生じる力が加えられることにより破断し、容易にノズル吸着部を除去することができる。
この結果、収納枠に収納された電子部品のメンテナンス時に被吸着部材が邪魔になることなく、メンテナンスの作業効率を向上させることができる。
また、被吸着部材の支持部と収納枠の破断可能な接合地点は収納枠の側壁の上端よりも下方に位置するため、ノズル吸着部を除去した際にバリが形成されても、バリが収納枠の側壁の上端より上に飛び出すことを防ぐことができる。
この結果、カバーにより収納枠の開口部を閉じる際にバリが邪魔になることもなく、スムーズに収納枠の開口部をカバーにより閉じることができる。
【0048】
請求項2の発明によれば、装着構造の係止凸部が、弾性付勢力によって収納枠の被係止凹部内に嵌め込まれた状態で、カバーが収納枠に装着されるため、収納枠からカバーを取り外す際の作業を容易化することができるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a shield member that shields an electronic component mounted on a substrate, and more particularly, to a mounting structure for a metal case and a cover constituting the shield member.
[0002]
[Prior art]
Conventionally, as a shield member that shields electronic components such as high-frequency devices mounted on a substrate, for example, as shown in FIG. 7, an integrated metal member is bent into a box shape and formed into a box shape. (See Patent Document 1).

The component 31 is reflow soldered to the substrate 30.
[0003]
However, since the shield member C configured as described above is configured to reflow solder the electronic component 31 using infrared energy that passes through the plurality of holes, the energy required for soldering is not sufficient. There is a possibility that the electronic component 31 cannot be reliably mounted on the substrate 30.
[0004]
In addition to the shield member C, a shield member B shown in FIG. 6 is provided.
The shield member B includes a metal case 50 including an opening 51 having an opening on one side for housing electronic components therein, and a cover 60 that closes the opening 51 of the metal case 50 (see Patent Document 2). ).
[0005]
According to the shield member B, since the metal case 50 includes the opening 51, when the electronic component housed in the metal case 50 is reflow soldered to a substrate (none of which is shown), the opening A sufficient supply of infrared energy can be obtained from 51, and the electronic component housed in the metal case 50 can be reliably mounted on the substrate.

[0010]
Furthermore, since the metal case 50 and the cover 60 constituting the shield member B are joined to each other by soldering or the like, the cover 60 is removed when maintaining electronic components housed in the metal case 50. In addition, in order to join the metal case 50 and the cover 60, work such as soldering is required.
