Description

【０００１】
【発明の属する技術分野】
本発明は、車のリアガラスやフロントガラスなどの窓ガラスに貼設されるフィルムアンテナの給電端子に電気的接続するフィルムアンテナ用給電装置に関するものである。
【０００２】
【従来の技術】
フィルムアンテナ用給電装置の一例が、特開２０００−１９６３２７号公報に示されている。この従来技術を簡単に説明する。接触子としての湾曲状の板バネの基端部が配設基板に接続固定され、この配線基板が接触子を突出させてケースに収容保持される。そして、接触子の突出部分を除くケースの取付面に、両面テープが貼着される。かかる構成で、フィルムアンテナの給電端子に接触子を弾接させた状態で、窓ガラスにケースが両面テープで貼着される。
【０００３】
【発明が解決しようとする課題】
上記従来技術にあっては、接触子として板バネを用いるために、フィルムアンテナ用給電端子に対する接触圧力が安定しない。また、板バネの弾性変形を確実に許容するためには、従来技術のごとくケースに収容する構造が簡単であるが、全体として小型に製造し難い。そこで、ケースに代えて、板バネをインサートして一体成形することを考えた場合に、板バネの弾性変形を考慮した金型が複雑となり、安価に製造がなし得ない。
【０００４】
ここで、フィルムアンテナ用給電装置は窓ガラスに両面テープで貼着されて固定されるものであり、固定のための機械的強度が大であるとは言い難い。そこで、フィルムアンテナ用給電装置が大型で重量が大であるほど、車の事故などによる衝撃で固定が外れて不測の事態を生じる虞がある。かかる理由から、フィルムアンテナ用給電装置をより小型軽量化することが望ましい。
【０００５】
本発明は、上述のごとき事情に鑑みてなされたもので、容易に小型軽量化することのできるフィルムアンテナ用給電装置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】
かかる目的を達成するために、本発明のフィルムアンテナ用給電装置は、フィルムアンテナの給電端子に電気的接続する給電装置であって、導電ケーブルを電気的接続したスプリングコネクタをインサートして、プランジャの先端を取付面より突出させて取付部材を絶縁樹脂で成形し、前記プランジャの先端を半球状であるとともに前記半球状の半径を前記フィルムアンテナの厚さの少なくとも３．５倍以上に設定し、前記プランジャの先端に前記給電端子を対向させた状態において前記取付面の前記フィルムアンテナが対応しない部分に、前記フィルムアンテナよりも厚い両面テープを貼着し、前記両面テープで前記取付部材を窓ガラスに貼着し、前記フィルムアンテナの給電部分を前記窓ガラスに貼着されない構造とし、前記両面テープが設けられていない前記取付面と前記窓ガラスの隙間に前記フィルムアンテナの前記給電部分を差し込んで、前記給電端子に前記プランジャを当接
【０００７】
また、フィルムアンテナの給電端子に電気的接続する給電装置であって、導電ケーブルを電気的接続したスプリングコネクタをインサートして、プランジャの先端を取付面より突出させて取付部材を絶縁樹脂で成形し、前記プランジャの先端を円錐状であるとともに前記円錐状の軸方向寸法を前記フィルムアンテナの厚さより長く設定し、前記プランジャの先端に前記給電端子を対向させた状態において前記取付面の前記フィルムアンテナが対応しない部分に、前記フィルムアンテナよりも厚い両面テープを貼着し、前記両面テープで前記取付部材を窓ガラスに貼着し、前記フィルムアンテナの給電部分を前記窓ガラスに貼着されない構造とし、前記両面テープが設けられていない前記取付面と前記窓ガラスの隙間に前記フィルムアンテナの前記給電部分を差し込んで、前記給電端子に前記プランジャを当接させるように構成しても良い。
【０００８】
さらに、前記プランジャの先端に前記給電端子を対向させた状態で、前記取付面で、前記プランジャの先端の突出部分を含む一隅の略矩形状に、前記フィルムアンテナの給電部分が対応するようになし、前記フィルムアンテナが対応しない部分の前記取付面に略Ｌ字状に前記両面テープを貼設して構成することもできる。
【０００９】
【発明の実施の形態】
以下、本発明の第１実施例を図１ないし図７を参照して説明する。図１は、本発明のフィルムアンテナ用給電装置の外観図であり、（ａ）は平面図、（ｂ）は正面図、（ｃ）は底面図、（ｄ）は右側面図、（ｅ）は左側面図である。図２は、図１は（ａ）のＡ−Ａ断面矢視拡大図である。図３は、フィルムアンテナの給電部分に本発明のフィルムアンテナ用給電装置を配設した平面図である。図４は、フィルムアンテナの給電端子にスプリングコネクタを弾接した状態の本発明のフィルムアンテナ用給電装置の縦断面拡大図である。図５は、図４のＢ−Ｂ断面矢視図である。図６は、プランジャの先端の半球状とフィルムアンテナの厚さを示す図である。図７は、プランジャの先端の変形例の円錐状とフィルムアンテナの厚さを示す図である。
【００１０】
まず、導電チューブの一端からプランジャ１０ａの先端が軸方向に移動自在に突出するスプリングコネクタ１０の導電チューブの他端部に、導電ケーブル１２の導電線が半田付けなどにより適宜に電気的接続されるとともに固定される。この導電ケーブル１２が電気的接続されたスプリングコネクタ１０が、金型にインサートされて絶縁樹脂により取付部材１４が一体成形される。なお、プランジャ１０ａの先端が、取付部材１４の取付面１４ａより若干突出した状態に形成される。
【００１１】
この取付部材１４のインサート成形において、スプリングコネクタ１０の導電チューブのプランジャ１０ａ側の先端部分を金型の凹孔に挿入するとともに導電チューブの他端側を適宜に押圧することで、金型に対してスプリングコネクタ１０を容易に位置決めできる。しかも、導電チューブから突出するプランジャ１０ａの突出部が、金型の凹孔で保護され、成形樹脂の侵入により移動が阻害されるようなことがない。もって、取付部材１４を成形するための金型の構造が比較的に簡単であり、安価に取付部材１４を成形することができる。
【００１２】
さらに、取付部材１４の取付面１４ａで、プランジャ１０ａの突出部分を含む一隅の略矩形状を除いて、略Ｌ字状に両面テープ１６が貼着される。この両面テープ１６の厚さは、剥離シール１６ａを剥がした状態で、フィルムアンテナ１８よりも厚く設定される。そして、図３および図５に示すごとく、フィルムアンテナ１８の給電端子１８ａにプランジャ１０ａの先端を弾接させて取付部材１４を窓ガラス２０に配設すると、両面テープ１６の略Ｌ字状の切り欠きにフィルムアンテナ１８の給電部分の直交する２辺が対応するように形成される。
【００１３】
かかる構成において、図５に示すごとく、窓ガラス２０に適宜に貼着されたフィルムアンテナ１８の給電部分の給電端子１８ａに、プランジャ１０ａの先端を弾接させるようにして、両面テープ１６で取付部材１４を窓ガラス２０に貼着固定させるならば、フィルムアンテナ１８の給電端子１８ａは、スプリングコネクタ１０および導電ケーブル１２を介して適宜なアンテナ回路に電気的接続され得る。なお、取付部材１４の貼着にあっては、フィルムアンテナ１８の給電部分の一隅の直交する２辺に、両面テープ１８の略Ｌ字状の切り欠きを対応させるための目標として、取付部材１４の側面に目印用の突起１４ｂが設けられている。この取付部材１４が貼着された状態で、プランジャ１０ａが給電端子１８ａに当接して弾力に抗して少しチューブ内に引き込まされた状態にあり、この弾力が所定の圧力となるようにスプリングコネクタ１０のスプリングが設定されることで、所望の小さな接触抵抗値が得られる。なお、両面テープ１６がフィルムアンテナ１８より厚いために、取付部材１４の貼着が窓ガラス２０から浮き上がるようなことがなく、確実に貼着がなし得る。
【００１４】
ところで、フィルムアンテナ１８の給電部分が、窓ガラス２０に貼着されない構造ならば、給電部分を窓ガラス２０に添ってずらすことができる。そこで、図６のごとく、プランジャ１０ａの先端を半球状とし、その半径Ｒをフィルムアンテナ１８の厚さｔよりもかなり大きくすることで、窓ガラス２０に予め取付部材１４を両面テープ１６で貼着した状態で取付面１４ａと窓ガラス２０との隙間に、フィルムアンテナ１８の給電部分を差し込み、プランジャ１０ａの先端の半球状によるくさび効果でプランジャ１０ａを押し上げて差し込みを許容させて、給電端子１８ａにプランジャ１０ａを当接する位置とすることができる。そして、両面テープ１６の略Ｌ字状の切り欠きに、フィルムアンテナ１８の給電部分の直交する２辺が当接するまで差し込んで、取付部材１４に対する位置決めとして作用させることができる。発明者らの実験によれば、フィルムアンテナ１８の差し込みより、プランジャ１０ａを押し上げるように軸方向に作用する力が軸方向と直交方向に作用する力より大きければ、プランジャ１０ａを弾力に抗して押し上げてフィルムアンテナ１８の差し込みが可能であった。そこで、フィルムアンテナ１８の厚さｔに対して、プランジャ１０ａの先端の半球状の半径Ｒが約３．５倍以上であれば良い。
【００１５】
さらに、フィルムアンテナ１８の差し込みによるくさび効果でプランジャ１０ａを押し上げるために変形例として、図７に示すごとく、プランジャ１０ａの先端を略円錐状としたものであっても良い。この略円錐状の軸方向の寸法ｄがフィルムアンテナ１８の厚さｔよりも大であれば良い。
【００１６】
なお、上記実施例ではスプリングコネクタ１０の導電チューブに対して導電ケーブル１２を半田付けするように説明したが、適宜なカシメによりスプリングコネクタ１０の導電チューブに導電ケーブル１２を電気的接続させても良い。また、取付部材１４の取付面１４ａに貼着される両面テープ１６は、略Ｌ字状に限られず、プランジャ１０ａの先端が突出する部分と両面テープ１６が貼着された部分とが直線で区分されても良い。さらに、取付部材１４の取付面１４ａに、プランジャ１０ａが突出する部分と段差で区分されて、両面テープ１６が貼着される略Ｌ字状に対応した部分が形成されても良い。かかる場合には、この段差と両面テープ１６の合計の厚さが、フィルムアンテナ１８より大きくなるように形成されれば良い。
【００１７】
【発明の効果】
以上説明したように、本発明のフィルムアンテナ用給電装置は構成されているので、以下のごとき格別な作用効果を奏する。
【００１８】
請求項１および請求項２記載のいずれのフィルムアンテナ用給電装置にあっても、導電ケーブルを電気的接続されたスプリングコネクタをインサートして取付部材を成形するので、小型かつ軽量に構成できる。しかも、成形金型の構造が簡単であって、安価に製造することができる。また、プランジャの先端が給電端子に対向した状態で、フイルムアンテナが対応しない取付部材の取付面の部分に、フイルムアンテナより厚い両面テープを貼着したので、取付部材を窓ガラスに両面テープで直接貼着することができ、本発明の給電装置を機械的に強固に固定することができる。そして、フィルムアンテナの給電部分を窓ガラスに貼着されない構造として窓ガラスに添ってずらすことができるようにし、窓ガラスに両面テープで予め貼着された取付部材のプランジャが突出する部分の取付面と窓ガラスとの隙間にフィルムアンテナの給電部分を差し込み、くさび効果でプランジャを弾力に抗して押し上げて差し込みを許容させて、プランジャを給電端子に弾接させることができる。フィルムアンテナの交換の際に窓ガラスに予め貼着された取付部材を活用でき、有益である。
【００１９】
請求項３記載のフィルムアンテナ用給電装置にあっては、取付装置の取付面に略Ｌ字状に両面テープを貼設するので、この略Ｌ字状の切り欠きをフィルムアンテナの給電部分の隅に一致させて、双方を容易に位置決めすることができる。

The double-sided tape may be attached in a substantially L shape to the mounting surface where the film antenna does not correspond.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1A and 1B are external views of a power supply device for a film antenna according to the present invention, wherein FIG. 1A is a plan view, FIG. 1B is a front view, FIG. 1C is a bottom view, FIG.

FIG. 6 is a diagram showing the hemisphere at the tip of the plunger and the thickness of the film antenna. FIG. 7 is a diagram showing a conical shape of a modification of the tip of the plunger and the thickness of the film antenna.
[0010]
First, the conductive wire of the conductive cable 12 is appropriately electrically connected by soldering or the like to the other end of the conductive tube of the spring connector 10 in which the tip of the plunger 10a protrudes from one end of the conductive tube so as to be movable in the axial direction. Fixed together. The spring connector 10 to which the conductive cable 12 is electrically connected is inserted into a mold, and the mounting member 14 is integrally formed of insulating resin. The tip of the plunger 10a is formed in a state slightly protruding from the mounting surface 14a of the mounting member 14.
[0011]
In the insert molding of the mounting member 14, the distal end portion of the spring connector 10 on the side of the plunger 10 a of the conductive tube is inserted into the concave hole of the mold and the other end side of the conductive tube is appropriately pressed to the mold. Thus, the spring connector 10 can be easily positioned. And the protrusion part of the plunger 10a which protrudes from a conductive tube is protected by the concave hole of a metal mold | die, and a movement is not inhibited by penetration | invasion of molding resin. Therefore, the structure of the mold for molding the mounting member 14 is relatively simple, and the mounting member 14 can be molded at a low cost.
[0012]
Further, the double-sided tape 16 is attached in a substantially L shape on the mounting surface 14a of the mounting member 14 except for a substantially rectangular shape including a protruding portion of the plunger 10a. The thickness of the double-sided tape 16 is set to be thicker than the film antenna 18 in a state where the peel seal 16a is peeled off. 3 and 5, when the mounting member 14 is disposed on the window glass 20 with the tip of the plunger 10a elastically contacting the feeding terminal 18a of the film antenna 18, the substantially L-shaped cut of the double-sided tape 16 is provided. It is formed so that two orthogonal sides of the feeding portion of the film antenna 18 correspond to the notch.
[0013]
In such a configuration, as shown in FIG. 5, the mounting member is attached with the double-sided tape 16 so that the tip of the plunger 10 a is elastically contacted to the feeding terminal 18 a of the feeding portion of the film antenna 18 appropriately attached to the window glass 20. If 14 is adhered and fixed to the window glass 20, the feeding terminal 18 a of the film antenna 18 can be electrically connected to an appropriate antenna circuit via the spring connector 10 and the conductive cable 12. In attaching the attachment member 14, the attachment member 14 is used as a target for making the substantially L-shaped notch of the double-sided tape 18 correspond to two orthogonal sides of one corner of the feeding portion of the film antenna 18. Protrusions 14b for marks are provided on the side surfaces. In a state where the attachment member 14 is adhered, the plunger 10a is in a state where the plunger 10a abuts against the power supply terminal 18a and is pulled into the tube a little against the elasticity, and the spring connector so that the elasticity becomes a predetermined pressure. By setting 10 springs, a desired small contact resistance value can be obtained. In addition, since the double-sided tape 16 is thicker than the film antenna 18, the attachment of the attachment member 14 does not float from the window glass 20, and can be reliably attached.
[0014]
By the way, if the feeding portion of the film antenna 18 is not attached to the window glass 20, the feeding portion can be shifted along the window glass 20. Therefore, as shown in FIG. 6, the tip of the plunger 10 a is hemispherical, and its radius R is considerably larger than the thickness t of the film antenna 18, so that the attachment member 14 is attached to the window glass 20 in advance with the double-sided tape 16. In this state, the feeding portion of the film antenna 18 is inserted into the gap between the mounting surface 14a and the window glass 20, and the plunger 10a is pushed up by the wedge effect due to the hemispherical shape at the tip of the plunger 10a to allow insertion, and the feeding terminal 18a It can be set as the position which the plunger 10a contacts. Then, it can be inserted into the substantially L-shaped notch of the double-sided tape 16 until two orthogonal sides of the feeding portion of the film antenna 18 come into contact with each other, and can act as positioning for the mounting member 14. According to the experiments by the inventors, if the force acting in the axial direction so as to push up the plunger 10a from the insertion of the film antenna 18 is larger than the force acting in the direction orthogonal to the axial direction, the plunger 10a is resisted against elasticity. The film antenna 18 could be inserted by pushing it up. Therefore, the hemispherical radius R at the tip of the plunger 10a may be about 3.5 times or more with respect to the thickness t of the film antenna 18.
[0015]
Furthermore, as shown in FIG. 7, the tip of the plunger 10a may have a substantially conical shape as shown in FIG. 7 in order to push up the plunger 10a by the wedge effect due to the insertion of the film antenna 18. The substantially conical axial dimension d may be larger than the thickness t of the film antenna 18.
[0016]
In the above embodiment, the conductive cable 12 is soldered to the conductive tube of the spring connector 10. However, the conductive cable 12 may be electrically connected to the conductive tube of the spring connector 10 by appropriate caulking. . Further, the double-sided tape 16 attached to the attachment surface 14a of the attachment member 14 is not limited to a substantially L shape, and the portion where the tip of the plunger 10a protrudes and the portion where the double-sided tape 16 is attached are separated by a straight line. May be. Furthermore, a portion corresponding to a substantially L shape to which the double-sided tape 16 is attached may be formed on the attachment surface 14a of the attachment member 14 by being separated by a step from the portion from which the plunger 10a protrudes. In such a case, the total thickness of the step and the double-sided tape 16 may be formed so as to be larger than that of the film antenna 18.
[0017]
【The invention's effect】
As described above, since the film antenna power supply device of the present invention is configured, the following advantageous effects can be obtained.
[0018]
In any of the film antenna power supply devices according to claims 1 and 2, since the mounting member is formed by inserting the spring connector electrically connected to the conductive cable, the structure can be made small and lightweight. Moreover, the structure of the molding die is simple and can be manufactured at low cost. In addition, the double-sided tape that is thicker than the film antenna is attached to the mounting surface of the mounting member that is not compatible with the film antenna with the tip of the plunger facing the power supply terminal. The power feeding device of the present invention can be mechanically and firmly fixed. Then, the feeding portion of the film antenna can be shifted along the window glass as a structure that is not attached to the window glass, and the attachment of the part where the plunger of the mounting member that is previously attached to the window glass with the double-sided tape protrudes The feeding portion of the film antenna is inserted into the gap between the surface and the window glass, and the plunger is pushed up against the elasticity by the wedge effect to allow the insertion, so that the plunger can be brought into elastic contact with the feeding terminal. An attachment member previously attached to the window glass can be utilized when replacing the film antenna, which is beneficial.
[0019]
In the power supply device for a film antenna according to claim 3, since the double-sided tape is affixed to the mounting surface of the mounting device in a substantially L shape, the substantially L-shaped notch is formed at the corner of the power feeding portion of the film antenna. Both of them can be easily positioned.
