Description

【0001】
【発明の属する技術分野】
本発明は、プリント基板における一側面側から他側面側への電子部品の実装を可能とした電子部品実装構造に関するものである。
【0002】
【従来の技術】
従来、図11に示される如く、電子部品1が適宜、実装されたプリント基板2に、回路特性の調整用としての抵抗器やコンデンサ等の後付け電子部品3を実装する場合、後付け電子部品3を実装するための実装用端子4を、他の電子部品1と同様に予め実装しておき、この実装用端子4に後付け電子部品3を上側より装着して半田付けすることにより実装していた。
【0003】
また、ケースやジョイントボックス等に、各電子部品1を内側としてプリント基板2が組み付けられた状態で、後付け電子部品3を実装する場合には、プリント基板2における各電子部品1が実装される実装面と反対側のいわゆる裏面側に、実装用端子4を実装しておき、この裏面側の実装用端子4に後付け電子部品3を装着して半田付けすることにより実装していた。
【0004】
【発明が解決しようとする課題】
しかしながら、上記プリント基板2における各電子部品1が実装される実装面と反対側の裏面側に、後付け電子部品3を実装する構造によれば、各電子部品1のプリント基板2に対するフロー、リフロー等のいわゆる自動方式の半田付け工程後、別工程で実装用端子4をプリント基板2に取付けた後、後付け電子部品3をその実装用端子4に実装する方式となるため、この別工程は専用自動機で対応するか、手作業等で対応することとなり、専用設備費や工程数の増加を招き、生産コストが増大するという問題があった。
【0005】
そこで、本発明の課題は、プリント基板の裏面側からの電子部品の実装が容易に行えると共に、製造工程数の増加を有効に防止する電子部品実装構造を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記の課題を解決するための技術的手段は、プリント基板に装着された実装用端子に後付け電子部品のリードを半田付けすることにより実装するための電子部品実装構造において、前記実装用端子は、前記後付け電子部品が実装される側の前記プリント基板の実装面に対向して配設された前記後付け電子部品実装用の部品取付部と、前記プリント基板の実装面側より挿通されて反対の裏面側に突出されると共に半田付けされた挿通脚部とを備え、前記プリント基板における前記部品取付部に対応する部分が、前記後付け電子部品の挿通自在な面積を有し、かつ切り離し手段により取り除き自在に支持されている取り除き基板部とされた点にある。
【0007】
また、前記実装用端子は、一方に前記部品取付部が備えられ、他方に前記挿通脚部が備えられた構造としてもよい。
【0008】
さらに、前記実装用端子は、中間部に前記部品取付部が備えられ、両端部にそれぞれ前記挿通脚部が備えられた構造としてもよい。
【0009】
また、前記実装用端子は、互いに対向して前記部品取付部と前記挿通脚部がそれぞれ備えられた一対の端子基板と、両端子基板を互いに連結する連結部とを有する構造としてもよい。
【0010】
【発明の実施の形態】
以下、本発明の第1の実施形態を図面に基づいて説明すると、図1ないし図3において、10は所定の配線パターンが形成されたプリント基板で、その上面側に、IC、抵抗器、コネクタ等の各種の電子部品11が実装されると共に、所定位置に一対の実装用端子12が実装されている。
【0011】
前記各実装用端子12は、銅板等の金属板材により形成されてなり、回路特性の調整用等に後付けされる抵抗器やコンデンサ等の電子部品、いわゆる後付け電子部品が実装される部品取付部としての部品取付溝13と、プリント基板10に形成された挿通孔14に電子部品11の実装面10a側より挿通されて反対の裏面10b側に突出される挿通脚部15とを備えている。
【0012】
前記挿通脚部15は、図2に示される如く、実装用端子12の右側下端に下向きに突出して備えられており、その幅方向中央部には割溝15aが形成されている。
【0013】
また、前記部品取付溝13は、実装用端子12の左側下端より上向きに形成されており、部品取付溝13の下半部は下方向に漸次拡開するテーパ部13aとされている。
【0014】
そして、プリント基板10の裏面10bより突出する実装用端子12の挿通脚部15が裏面10b側のランド部16等に半田17付けされた状態で、実装用端子12の部品取付溝13はプリント基板10の実装面10aに対向して配置される構造とされている。
【0015】
また、プリント基板10における一対の実装用端子12の各部品取付溝13に対応した部分には、両部品取付溝13にわたって装着される後付け電子部品が挿通自在な適宜面積を有する矩形の取り除き基板部18が備えられており、取り除き基板部18の周囲にはスリットやミシン目等の切り離し手段19が形成され、該切り離し手段19により、取り除き基板部18が容易に取り除き自在にプリント基板10に支持されている。
【0016】
本実施形態は以上のように構成されており、図4に示される如く、後付け電子部品21を両実装用端子12の部品取付溝13間にわたって実装する場合には、先ず、プリント基板10より切り離し手段19を利用して取り除き基板部18を取り除く。
【0017】
次に、その取り除き開口23を利用して裏面10b側より後付け電子部品21を挿入して、各部品取付溝13に後付け電子部品21両側の各リード21aを装着し、各リード21aを実装用端子12側に半田付けすることによって実装できる。
【0018】
従って、図5に示される如く、ケースやジョイントボックス等のハウジング体25にプリント基板10が組み付けられ、各電子部品11や各実装用端子12がハウジング体25に内蔵された状態であっても、取り除き基板部18を取り除くことによって、両実装用端子12の部品取付溝13間にわたって後付け電子部品21を実装することができる。
【0019】
また、プリント基板10に対する各実装用端子12の実装に際しては、通常の各電子部品11をプリント基板10に実装する際のフロー、リフローの半田付け工程で同時に実装することができ、ここに、製造工程数の増加を有効に防止でき、また、専用の設備費も削減でき、生産コスト低減が図れる。
【0020】
そして、この半田付け工程において、取り除き基板部18がスリットやミシン目等の切り離し手段19によりプリント基板10に支持されているため、実装用端子12の部品取付溝13部分への不用意な半田付着も有効に防止できる。
【0021】
さらに、取り除き基板部18を取り除くことによって、プリント基板10の裏面10b側からの後付け電子部品21の実装も容易の行え、至便である。
【0022】
また、実装用端子12は一方に部品取付溝13が備えられると共に、他方に挿通脚部15が備えられ、プリント基板10に対する実装状態にあっては、いわゆる片持ちタイプとされており、実装のスペースが少なくて済み、省スペース化が図れ、図6に示される如く、プリント基板10の端縁部に配置される場合に最適である。
【0023】
さらに、回路特性の調整用としてチップ部品を実装する方式にあっては、回路特性の再修正に際してプリント基板10自体の損傷を招くおそれがあるが、本実施形態にあっては、両実装用端子12の部品取付溝13に後付け電子部品21の各リード21aを半田付けする方式としているため、回路特性の再修正を行う場合等において、プリント基板10自体の損傷も有効に防止できる利点がある。
【0024】
図7は第2の実施形態における実装用端子12を示しており、第1の実施形態と同様構成部分は同一符号を付し、その説明を省略する。
【0025】
即ち、この実装用端子12は銅板等の金属板材を適宜折曲形成してなり、互いに僅かの間隙を有して対向配置された一対の端子基板12a、12bと、両端子基板12a、12bの上端縁部を互いに連結する連結部12cとを備え、各端子基板12a、12bは第1の実施形態と同様の形状に形成され、それぞれ対応して部品取付溝13および挿通脚部15が備えられている。
【0026】
そして、その使用に際しては、第1の実施形態と同様に使用される。従って、本実施形態においても第1の実施形態と同様の効果を奏すると共に、プリント基板10への実装部分および後付け電子部品21の部品取付溝13がそれぞれ2個所となり、プリント基板10に対する実装用端子12の取付状態や実装用端子12の部品取付溝13に対する後付け電子部品21の取付状態が安定するという利点もある。
【0027】
図8および図9は第3の実施形態を示しており、第1の実施形態と同様構成部分は同一符号を付し、その説明を省略する。
【0028】
即ち、本実施形態では、各実装用端子12は銅板等の金属板材により形成されてなり、その幅方向中間部に部品取付溝13が備えられ、両端部にそれぞれ挿通脚部15が備えられた構造とされている。
【0029】
そして、その使用に際しては、第1の実施形態と同様に使用される。この際、実装用端子12の両側の挿通脚部15は取り除き基板部18をまたいだ取り除き基板部18の両側方に位置して実装され、実装用端子12はプリント基板10に対して両側で支持されたいわゆる両持ちタイプとされ、第1の実施形態と同様、製造工程数の増加を有効に防止でき、また、専用の設備費も削減でき、生産コスト低減が図れる利点や、取り除き基板部18を取り除くことによって、プリント基板10の裏面10b側からの後付け電子部品21の実装も容易の行える利点もある。
【0030】
さらに、両側の挿通脚部15によってプリント基板10に両持ち支持されるため、実装用端子12の取付状態が安定するという利点もある。
【0031】
図10は第4の実施形態における実装用端子12を示しており、第3の実施形態と同様構成部分は同一符号を付し、その説明を省略する。
【0032】
即ち、この実装用端子12は銅板等の金属板材を適宜折曲形成してなり、互いに僅かの間隙を有して対向配置された一対の端子基板12d、12eと、両端子基板12d、12eの上端縁部を互いに連結する連結部12fとを備え、各端子基板12d、12eは第3の実施形態と同様の形状に形成され、それぞれ対応して部品取付溝13および挿通脚部15が備えられている。
【0033】
そして、その使用に際しては、第3の実施形態と同様に使用される。従って、本実施形態においても第3の実施形態と同様の効果を奏すると共に、プリント基板10への実装部分および後付け電子部品21の部品取付溝13がそれぞれ2個所となり、プリント基板10に対する実装用端子12の取付状態や実装用端子12の部品取付溝13に対する後付け電子部品21の取付状態がより安定するという利点もある。
【0034】
なお、上記各実施形態において、部品取付部として部品取付溝13を採用した構造を示しているが、載置部等その他の構造であってもよく、実施形態の形状に何ら限定されない。
【0035】
また、後付け電子部品21として、回路特性調整用の抵抗器やコンデンサに限らず、その他の電子部品であってもよい。
【0036】
【発明の効果】
以上のように、本発明の電子部品実装構造によれば、実装用端子は、後付け電子部品が実装される側のプリント基板の実装面に対向して配設された後付け電子部品実装用の部品取付部と、プリント基板の実装面側より挿通されて反対の裏面側に突出されると共に半田付けされた挿通脚部とを備え、プリント基板における部品取付部に対応する部分が、後付け電子部品の挿通自在な面積を有し、かつ切り離し手段により取り除き自在に支持されている取り除き基板部とされたものであり、通常のフロー、リフローの半田付け工程で実装用端子も同時に実装することができ、製造工程数の増加を有効に防止でき、また、取り除き基板部を取り除くことによってプリント基板の裏面側からの後付け電子部品の実装も容易に行えるという利点がある。
【0037】

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 3, reference numeral 10 denotes a printed circuit board on which a predetermined wiring pattern is formed. Various electronic components 11 such as the above are mounted, and a pair of mounting terminals 12 are mounted at predetermined positions.
[0011]
Each of the mounting terminals 12 is formed of a metal plate material such as a copper plate, and is used as a component mounting portion on which electronic components such as resistors and capacitors that are retrofitted for adjusting circuit characteristics or the like, so-called retrofitted electronic components are mounted. The component mounting groove 13 and an insertion leg portion 15 that is inserted into the insertion hole 14 formed in the printed board 10 from the mounting surface 10a side of the electronic component 11 and protrudes to the opposite back surface 10b side.
[0012]
As shown in FIG. 2, the insertion leg 15 is provided to protrude downward from the lower right end of the mounting terminal 12, and a split groove 15 a is formed at the center in the width direction.
[0013]
The component mounting groove 13 is formed upward from the lower left end of the mounting terminal 12, and the lower half of the component mounting groove 13 is a tapered portion 13a that gradually expands downward.
[0014]
The component mounting groove 13 of the mounting terminal 12 is formed in the state where the insertion leg portion 15 of the mounting terminal 12 protruding from the back surface 10b of the printed circuit board 10 is soldered 17 to the land portion 16 or the like on the back surface 10b side. It is set as the structure arrange | positioned facing 10 mounting surfaces 10a.
[0015]
In addition, in a portion corresponding to each component mounting groove 13 of the pair of mounting terminals 12 in the printed circuit board 10, a rectangular removal substrate portion having an appropriate area through which a post-installed electronic component mounted over both the component mounting grooves 13 can be inserted. 18 is provided, and separation means 19 such as slits and perforations are formed around the removal substrate portion 18, and the removal substrate portion 18 is supported on the printed circuit board 10 by the separation means 19 so that it can be easily removed. ing.
[0016]
The present embodiment is configured as described above. As shown in FIG. 4, when mounting the retrofitted electronic component 21 between the component mounting grooves 13 of both the mounting terminals 12, first, it is separated from the printed circuit board 10. The substrate portion 18 is removed using the means 19.
[0017]
Next, the post-attachment electronic component 21 is inserted from the back surface 10b side using the removal opening 23, the leads 21a on both sides of the post-attachment electronic component 21 are mounted in the component mounting grooves 13, and the leads 21a are mounted on the mounting terminals. It can be mounted by soldering to the 12 side.
[0018]
Therefore, as shown in FIG. 5, even when the printed circuit board 10 is assembled to the housing body 25 such as a case or a joint box and each electronic component 11 or each mounting terminal 12 is built in the housing body 25, By removing the substrate portion 18 to be removed, the retrofitted electronic component 21 can be mounted across the component mounting grooves 13 of both mounting terminals 12.
[0019]
In addition, when mounting each mounting terminal 12 on the printed circuit board 10, it is possible to simultaneously mount the electronic components 11 on the printed circuit board 10 in the flow and reflow soldering process. The increase in the number of processes can be effectively prevented, and the dedicated equipment cost can be reduced, thereby reducing the production cost.

[0023]
Further, in the method of mounting chip parts for adjusting the circuit characteristics, there is a risk of causing damage to the printed circuit board 10 when the circuit characteristics are re-corrected. In the present embodiment, both mounting terminals are used. Since the lead 21a of the post-attached electronic component 21 is soldered to the twelve component mounting grooves 13, there is an advantage that damage to the printed circuit board 10 itself can be effectively prevented when the circuit characteristics are re-corrected.
[0024]
