Description

【0001】
【発明の属する技術分野】
本発明は、自動車ガラスアンテナ用のコイル装置に関する。
【0002】
【従来の技術】
従来、図3に示すとおり、多数本のヒータ線22とヒータ線22に給電する複数のバスバ15a、15b、15cとを有する通電加熱式のデフォッガ23が自動車の後部窓ガラス板21に設けられており、バスバ15a、15bと直流電源10との間にチョークコイル19及び高周波チョークコイル1(後述する図2における高周波チョークコイル31に相当)が接続されている自動車用ガラスアンテナが知られている。
【0003】
この従来例では、デフォッガ23の給電点14にケーブル27を接続して、
デフォッガ23に励起された受信信号をデフォッガ23の給電点14、ケーブル27を介して、受信機20に送っていた。
【0004】
この従来例で用いていたコイル装置を図2に示した(特開平5−75321号参照)。この従来のコイル装置では、樹脂製のケース34にコイル芯32に巻かれた高周波チョークコイル31が収納され、コイルの一端35aは脚部33aと電気的に接続され、コイルの他端35bは脚部33c及び端子片33bと電気的に接続されていた。
【0005】
脚部33aはバスバ15a上に半田にて接着され、脚部33cはダミーパターン(不図示)上に半田にて接着されており、端子片33bがチョークコイル19にリード線28を介して接続されていた。
【0006】
このため、デフォッガの給電点14をバスバ15aとは別に設ける必要があり、後部窓ガラス板21の有効なスペース利用の点で無駄となる問題があった。また、デフォッガの給電点14にケーブル27を接続する工程が必要になり、生産性が悪い問題があった。
【0007】
さらに、デフォッガの給電点14を設ける代わりに給電点をバスバ上に設けようとしても、車種によってはバスバが窓枠に隠れるため、複数の端子をバスバ上に設けることができない問題もあった。
【0008】
【発明が解決しようとする課題】
本発明は、従来技術の有する前述の欠点を解消する自動車ガラスアンテナ用のコイル装置の提供を目的とする。
【0009】
【課題を解決するための手段】
本発明は、前述の課題を解決すべくなされたものであり、高周波チョークコイルと、回路基板と、ケーブルとが備えられており、
回路基板の片側には金属製の第1の脚部が設けられ、回路基板の他の側には金属製の第2の脚部が設けられており、さらに、回路基板には金属製の端子片が設けられており、
回路基板には少なくとも3つの孔が設けられており、
高周波チョークコイルの一端は第1の孔に挿入されて固着手段により回路基板に固着されており、
高周波チョークコイルの他端は第2の孔に挿入されて固着手段により回路基板に固着されており、
回路基板の上面と高周波チョークコイルの下部との間には所定の間隔が設けられ、高周波チョークコイルの下方の回路基板の箇所には第3の孔が設けられ、さらに、ケーブルの一端は第3の孔に挿入されて固着手段により回路基板に固着されており、
高周波チョークコイルの一端と、第1の脚部と、ケーブルの一端とは電気的に接続されており、
高周波チョークコイルの他端と端子片とは電気的に接続されていることを特徴とする自動車ガラスアンテナ用のコイル装置を提供する。
【0010】
【発明の実施の形態】
以下、本発明を図面に従って詳細に説明する。図1は本発明の自動車ガラスアンテナ用のコイル装置の一実施例の構成図である。
【0011】
図1において、1は高周波チョークコイル、2はコイル芯、3は金属製の端子片、4は回路基板、5aは高周波チョーク1のコイルの一端、5bは高周波チョークコイル1の他端、6aは金属製の第1の脚部、6bは金属製の第2の脚部、7はケーブル、7aはケーブルの一端、8は必要に応じて設けられるコンデンサ、9a、9b、9cは半田、Lは回路基板4の上面と高周波チョークコイル1の下部との間隔である。
【0012】
本発明の自動車ガラスアンテナ用のコイル装置には、高周波チョークコイル1と、回路基板4と、ケーブル7とが備えられている。回路基板4の片側には第1の脚部6aが設けられ、回路基板4の他の側には第2の脚部6bが設けられている。脚部6a、6bをそれぞれ回路基板4に設ける手段は、ハトメ金具等の金属片により、回路基板4と脚部6a、6bとをそれぞれ挟み込んでもよく、回路基板4の上に設けられた導体パターンと脚部6a、6bとをそれぞれ半田等により接着してもよく、脚部6a、6bを回路基板4に接着剤によりそれぞれ接着してもよく、特に限定されない。
【0013】
他端5bと第2の脚部6bとの間の回路基板4の箇所には金属製の端子片3が設けられている。図1では端子片3は回路基板4の上面から上方に伸長している。端子片3を回路基板4に設ける手段は、上記した脚部6a、脚部6bを回路基板4に設ける手段と同様である。
【0014】
回路基板4には3つの孔(不図示)が設けられており、一端5aは第1の孔に挿入されて半田付け等の固着手段により回路基板1に固着されている。高周波チョークコイル1の他端5bは第2の孔に挿入されて半田付け等の固着手段により回路基板4に固着されている。
【0015】
回路基板4の上面と高周波チョークコイル1の下部との間には所定の間隔Lが設けられている。高周波チョークコイル1の下方の回路基板4の箇所には第3の孔が設けられ、一端7a近傍は回路基板4の上面と高周波チョークコイル1の下部との間に配され、さらに、一端7aは第3の孔に挿入されて半田付け等の固着手段により回路基板4に固着されている。
【0016】
一端5aと、第1の脚部6aと、一端7aとは半田付け等の接続手段により電気的に接続されている。他端5bと端子片3とは半田付け等の接続手段により電気的に接続されている。他端5bと第2の脚部6bとは半田付け等の接続手段により電気的に接続されていてもよいが電気的に接続されていない方が好ましい。その理由は、第1の脚部6aと第2の脚部6bとが同じバスバに固着しても一端5aと他端5bとが短絡しないからである。なお、第1の脚部6aと第2の脚部6bとを同じバスバに固着する場合には、ダミーパターンは不要である。
【0017】
コイル芯2の形状は円筒形が好ましい。コイル芯2の材料としては、フェライト、センダスト等が通常用いられるが、これに限定されず、高周波特性を向上させるものであれば他の材料も使用できる。
【0018】
コンデンサ8は、第1の脚部6aとケーブル7との間に電気的に接続されるように必要に応じて設けられるものである。すなわち、本発明の自動車ガラスアンテナ用のコイル装置が後部窓ガラス板21に取付けられる場合には、コンデンサ8は、受信機20の入力端とバスバとの間に電気的に接続されるようになり、直流阻止の機能を有する。コンデンサ8が、第1の脚部6aとケーブル7との間に電気的に接続されるようにするには、回路基板4に設けられた導体パターンによるものであっても、他の手段であってもよい。
【0019】
図3に示す自動車用ガラスアンテナ装置に本発明の自動車ガラスアンテナ用のコイル装置が使用できる。例えば、第1の脚部6a及び第2の脚部6bをバスバ15aに半田付けする。ケーブル7の他端(不図示)は受信機20の入力端に電気的に接続する。
【0020】
バスバ15a、15bと直流電源10との間に、チョークコイル19と高周波チョークコイル1との直列接続回路を接続し、AM放送帯にてチョークコイル19のインピーダンスを大きくすることによって、直流電源10からデフォッガ23へ直流電流は流すものの、放送帯域の受信信号電流は遮断している。デフォッガ23に励起されるAM放送帯の受信電流が車体にできるだけ漏れないようにするためである。
【0021】
高周波チョークコイル1は、FM放送帯等の高周波帯において、高インピーダンスとなるもので、これらはFM放送帯等の高周波帯では誘導性のインダクタンスを有する。
【0022】
FM放送帯等の高周波帯においては、チョークコイル19の自己共振周波数が低く、チョークコイル19のインピーダンスに容量性が現れて通常低インピーダンスとなるので、高周波チョークコイル1がこれを代行する。なお、11はノイズ吸収用のコンデンサである。高周波チョークコイル1は0.1〜100μH程度が通常使用される。
【0023】
ここで、高周波帯としては、FM放送帯の他、テレビVHF帯(90〜108MHz、170〜222MHz)、テレビUHF帯(470〜770MHz)、北米及び欧州のテレビVHF帯(45〜86MHz、175〜225MHz)、自動車電話用の800MHz帯(810〜960MHz)、自動車電話用の1.5GHz帯(1.429〜1.501GHz)及びUHF帯(300MHz〜3GHz)等が挙げられる。
【0024】
【実施例】
図1に示すような自動車ガラスアンテナ用のコイル装置を製作した。各部の寸法、定数等の仕様は以下のとおりである。脚部6aは、脚部6aに孔(不図示)を設け、この孔と第1の孔とを合わせ、円筒状のハトメ金具を両孔に貫通させてかしめることにより回路基板4に固着した。脚部6bも回路基板4に設けた第4の孔(不図示)を用いて同様の手段で回路基板4に固着した。一端5aは第1の孔に貫通させたハトメ金具に挿入させて半田付けした。
【0025】
端子3は端子3に孔(不図示)を設け、この孔と第2の孔とを合わせ、円筒状のハトメ金具を両孔に貫通させてかしめることにより回路基板4に固着した。他端5bは第2の孔に貫通させたハトメ金具に挿入させて半田付けした。ケーブル7としては樹脂被膜付きの銅製のリード線を用いた。

図3に示す自動車用ガラスアンテナ装置に、本発明の自動車ガラスアンテナ用のコイル装置を使用した。第1の脚部6a及び第2の脚部6bをバスバ15aに半田付けした。ケーブル7の他端は受信機20の入力端に電気的に接続した。AM放送帯及びFM放送帯を受信したところ良好に受信できた。
【0027】
【発明の効果】
本発明では、第1の脚部と、ケーブルの一端とが電気的に接続されているために、第1の脚部をバスバに電気的に接続することによりデフォッガに励起された受信信号をケーブルを介して、受信機に送ることができる。
【0028】
したがって、デフォッガの給電点をバスバとは別に設ける必要がなく、後部窓ガラス板の有効なスペース利用が図れる。さらに、デフォッガの給電点にケーブルを接続する工程が不要になり、生産性を向上できる。
【0029】
さらに、回路基板の上面と高周波チョークコイルの下部との間には所定の間隔が設けられており、高周波チョークコイルの一端近傍が所定の間隔に配されているため、コイル装置自体が小型化できる。

[0012]
The coil device for an automobile glass antenna of the present invention includes a high frequency choke coil 1, a circuit board 4, and a cable 7. A first leg 6 a is provided on one side of the circuit board 4, and a second leg 6 b is provided on the other side of the circuit board 4. The means for providing the leg portions 6a and 6b on the circuit board 4 may be such that the circuit board 4 and the leg portions 6a and 6b may be sandwiched by metal pieces such as eyelet fittings, respectively, or a conductor pattern provided on the circuit board 4 And the leg portions 6a and 6b may be bonded to each other with solder or the like, and the leg portions 6a and 6b may be bonded to the circuit board 4 with an adhesive, respectively.
[0013]
A metal terminal piece 3 is provided at a location on the circuit board 4 between the other end 5b and the second leg 6b. In FIG. 1, the terminal piece 3 extends upward from the upper surface of the circuit board 4. The means for providing the terminal piece 3 on the circuit board 4 is the same as the means for providing the leg part 6 a and the leg part 6 b on the circuit board 4.
[0014]
The circuit board 4 is provided with three holes (not shown), and one end 5a is inserted into the first hole and fixed to the circuit board 1 by fixing means such as soldering. The other end 5b of the high frequency choke coil 1 is inserted into the second hole and fixed to the circuit board 4 by fixing means such as soldering.

This is to prevent the reception current of the AM broadcast band excited by the defogger 23 from leaking into the vehicle body as much as possible.
[0021]
The high frequency choke coil 1 has high impedance in a high frequency band such as an FM broadcast band, and these have inductive inductance in a high frequency band such as an FM broadcast band.
[0022]
In the high frequency band such as the FM broadcasting band, the self-resonant frequency of the choke coil 19 is low, and the impedance appears in the impedance of the choke coil 19 so that the impedance is usually low. Therefore, the high frequency choke coil 1 acts as a proxy. Reference numeral 11 denotes a noise absorbing capacitor. As for the high frequency choke coil 1, about 0.1-100microH is normally used.

The leg 6b was also fixed to the circuit board 4 by the same means using a fourth hole (not shown) provided in the circuit board 4. The one end 5a was inserted and soldered into a grommet fitting penetrated through the first hole.
[0025]
The terminal 3 was fixed to the circuit board 4 by providing a hole (not shown) in the terminal 3, aligning the hole and the second hole, and penetrating a cylindrical eyelet through both holes.
