Description

【０００１】
【発明の属する技術分野】
本発明は、アンテナ素子の固定方法とアームに固定されたアンテナ素子に関するものである。
【０００２】
【従来の技術】
従来のアンテナ素子をアームに固定する方法を、図７により説明する。
【０００３】
アーム１０１の挿通孔１０２にアンテナ素子１０３を挿通させた後、アーム１０１内壁とアーム１０１の内側のアンテナ素子１０３との間隙に、この間隙より大きい断面の矢を、上下同時に通して図示のようにアンテナ素子１０３を変形させている。
【０００４】
アンテナ素子１０３を矢により上下方向に潰した時にアンテナ素子１０３の断面は横方向に拡がり楕円形状となり、拡がった部分が挿通孔１０２に当接し、又アーム１０１内部のアンテナ素子１０３も拡がるため、アンテナ素子１０３がアーム１０１の左右方向にズレ抜けることはなく、アンテナ素子１０３がアーム１０１に固定される。
【０００５】
また、本出願人は、既に特願２００２−２０５１８５「アンテナ素子の固定方法とアームに固定されたアンテナ素子」、特願２００３−１２３０３９「アンテナ素子の固定方法とアームに固定されたアンテナ素子」を出願している。これは例えば、図８に示すように、アーム１の挿通孔２にアンテナ素子３を挿通させ、アーム１にアンテナ素子３を直角状に固定するアンテナ素子３の固定方法であって、アンテナ素子３が挿通孔２に挿通され、アーム１と当接する挿通孔２の近傍をプレス加工して挿通孔２を変形させてアンテナ素子３とアーム１とを接触・固定させるようにしたアンテナ素子の固定方法である。プレス加工による加圧箇所は符号１１、１２で示すアーム１の近傍の円弧部分で、円弧状のキズが発生している。
【０００６】
これは、矢を用いることなく、プレス加工により、挿通孔２近傍のアーム１をプレス加工し、挿通孔２を変形させて接触・固定させるようにしたものである。
【０００７】
【発明が解決しようとする課題】
上記の従来のアンテナ素子１０３をアーム１０１に固定する方法の欠点としては、アーム１０１内壁とアーム１０１の内側のアンテナ素子１０３との間隙に矢を通す手間と、又、矢を引き抜く時にアンテナ素子１０３の折損を無くするため、潤滑のために多量の油が必要で、カシメた後、アーム１０１内部の油分を取り除く酸洗等の脱脂工程が必要である。
【０００８】
また、アーム１と当接する挿通孔２の近傍をプレス加工して挿通孔２を変形させて固定させる固定方法では、アーム１の断面が真円で加圧箇所にキズが発生する。キズの発生を無くして挿通孔２を縮小させようとすると、アンテナ素子３以外の部分でシワが発生する等の欠点があった。
【０００９】
【課題を解決するための手段】
そこで、本発明は、上記の事情に鑑み、矢を通す手間と油分を取り除く工程を省略してコストダウンを図り、また、アームにキズやシワを発生させることなく、アンテナ素子とアームとを接触・固定させるべく、アームの挿通孔にアンテナ素子を挿通させ、アームにアンテナ素子を直角状に固定するアンテナ素子の固定方法であって、アームの対向した箇所の長手方向に凹溝を刻設し、凹溝の箇所に挿通孔を穿設し、アームの挿通孔にアンテナ素子を挿入させ、凹溝が閉じる方向にアームをプレス加工して挿通孔を変形させてアンテナ素子とアームとを接触・固定させるようにしたアンテナ素子の固定方法とした。
【００１０】
また、本発明は、具体的には凹溝がＶ字型凹溝である。
【００１１】
さらに、本発明は、具体的には凹溝がコ字型凹溝である。
【００１２】
さらにまた、本発明は、上記の方法により製作されたアームに固定されたアンテナ素子である。
【００１３】
【発明の実施の態様】
本発明を添付する図面に示す具体的な実施例に基づいて、以下詳細に説明する。
【００１４】
本発明は、図１に示すように、アーム１の挿通孔２にアンテナ素子３を挿通させ、アーム１にアンテナ素子３を直角状に固定するアンテナ素子３の固定方法であって、アーム１の対向した箇所の長手方向に凹溝を刻設し、凹溝の箇所に挿通孔２を穿設し、アーム１の挿通孔２にアンテ素子３を挿入させ、凹溝が閉じる方向にアーム１をプレス加工して挿通孔２を変形させてアンテナ素子３とアーム１とを接触・固定させるようにしたアンテナ素子の固定方法である。
【００１５】
本発明では、矢を用いることなく、プレス加工により、挿通孔２近傍のアーム１をプレス加工し、挿通孔２を変形させて接触・固定させるようにしたものである。
【００１６】
また、本発明では、アーム１にキズやシワを発生させることなく、アンテナ素子３とアーム１とを接触・固定させるものである。
【００１７】
先ず、図２・図３に示すものは、例えば、プレス加工が外径２２ｍｍの円筒体のアルミ製アーム１の孔径８．１ｍｍの挿通孔２に、外径８ｍｍのアルミ製アンテナ素子３を挿通し、アーム１をプレス加工して挿通孔２を変形させてアンテナ素子３とアーム１とを接触・固定させる。
【００１８】
本発明では、図３に示すように、アーム１には対向した箇所の長手方向に凹溝２１を刻設し、凹溝２１の箇所に挿通孔２を穿設する。
【００１９】
アーム１の中心軸Ｃを通る直線と周壁との交差箇所（対向した箇所）に凹溝２１を刻設する。また、凹溝２１はアーム１の長手方向の全長にわたり刻設する。凹溝２１として図２Ａに示すＶ字型凹溝２１ａ、図２Ｂに示すコ型凹溝２１ｂ、図２Ｃに示すＶ字型凹溝２１ｃがある。
【００２０】
挿通孔２は、アーム１の長手方向の所要間隔を隔てた位置に穿設する。凹溝２１の幅Ｗは挿通孔２の直径より小さく形成する。
【００２１】
図２ＡのＶ字型凹溝２１ａの箇所に挿通孔２をドリルにより穿設する際、対面出口側でドリルが突部に当たりドリルの芯ぶれが起こりやすいので、図２Ｂに示すコ型凹溝２１ｂに形成しておくと、コ型凹溝２１ｂの箇所に挿通孔２をドリルにより穿設する際、対面出口側でドリルが平面部に当たりドリルは芯ぶれを起こすようなことはなく、挿通孔２の孔開けが正確且つ容易にでき、図２Ｃに示すＶ字型凹溝２１ｃであっても対面出口側でドリルは略平面部に当たりドリルは芯ぶれを起こすようなことはなく、挿通孔２の孔開けが正確且つ容易にできる。
【００２２】
図４〜図７によりアーム１の挿通孔２にアンテナ素子３を挿通させ、アーム１にアンテナ素子３を直角状に固定するアンテナ素子の固定方法について説明する。
【００２３】
図４はアーム１の挿通孔２にアンテナ素子３を挿入しプレス加工前の状態で、アーム１の直径はＬで、アンテナ素子３の直径はＤである。
【００２４】

【００２５】
図６は下型２２ａの上面と上型２２ｂの下面とが当接し、凹溝２１が閉じる方向にプレス加工し、挿通孔２を変形させてアンテナ素子３とアーム１とを接触・固定させた状態である。挿通孔２は上下方向で孔径が縮まりアンテナ素子３に食い込んでいき、凹溝２１の幅Ｗは狭くなる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for fixing an antenna element and an antenna element fixed to an arm.
[0002]
[Prior art]
A conventional method of fixing an antenna element to an arm will be described with reference to FIG.
[0003]
After the antenna element 103 is inserted through the insertion hole 102 of the arm 101, an arrow having a cross section larger than the gap is simultaneously passed vertically through the gap between the inner wall of the arm 101 and the antenna element 103 inside the arm 101 as shown in the figure. The antenna element 103 is deformed.
[0004]
When the antenna element 103 is crushed in the vertical direction by an arrow, the cross section of the antenna element 103 expands in the horizontal direction and becomes an elliptical shape, and the expanded portion comes into contact with the insertion hole 102, and the antenna element 103 inside the arm 101 also expands. The element 103 is not displaced in the left-right direction of the arm 101, and the antenna element 103 is fixed to the arm 101.
[0005]
In addition, the present applicant has already filed Japanese Patent Application No. 2002-205185, entitled "Method of fixing antenna element and antenna element fixed to arm", and Japanese Patent Application No. 2003-123039, "Method of fixing antenna element and antenna element fixed to arm". Filed. For example, as shown in FIG. 8, this is a method for fixing the antenna element 3 in which the antenna element 3 is inserted into the insertion hole 2 of the arm 1 and the antenna element 3 is fixed to the arm 1 at right angles. Is inserted into the insertion hole 2, and the vicinity of the insertion hole 2 in contact with the arm 1 is pressed to deform the insertion hole 2 so that the antenna element 3 and the arm 1 are brought into contact and fixed with each other. It is. The pressure applied by the press working is an arc portion near the arm 1 indicated by reference numerals 11 and 12, and an arc-shaped scratch is generated.
[0006]
In this method, the arm 1 in the vicinity of the insertion hole 2 is pressed by pressing without using an arrow, and the insertion hole 2 is deformed to contact and fix.
[0007]
[Problems to be solved by the invention]
Disadvantages of the above-described conventional method of fixing the antenna element 103 to the arm 101 are that it takes time to pass an arrow through the gap between the inner wall of the arm 101 and the antenna element 103 inside the arm 101, and the antenna element 103 when the arrow is pulled out. In order to eliminate breakage of the arm 101, a large amount of oil is required for lubrication. After caulking, a degreasing step such as pickling for removing oil inside the arm 101 is required.
[0008]
Further, in the fixing method in which the vicinity of the insertion hole 2 in contact with the arm 1 is pressed to deform and fix the insertion hole 2, the cross section of the arm 1 is a perfect circle, and scratches occur at the pressurized portion. Attempting to reduce the insertion hole 2 by eliminating scratches has the disadvantage that wrinkles occur in portions other than the antenna element 3.
[0009]
[Means for Solving the Problems]
In view of the above circumstances, the present invention eliminates the labor of passing arrows and the step of removing oil, thereby reducing costs, and allowing the antenna element to contact the arm without causing scratches and wrinkles on the arm. A method for fixing an antenna element in which an antenna element is inserted into an insertion hole of an arm and the antenna element is fixed at a right angle to the arm in order to fix the arm. The antenna element is inserted into the insertion hole of the arm, the arm is pressed in the direction in which the groove closes, the insertion hole is deformed, and the antenna element contacts the arm. The antenna element was fixed so as to be fixed.
[0010]
Further, in the present invention, specifically, the concave groove is a V-shaped concave groove.
[0011]
Further, in the present invention, specifically, the concave groove is a U-shaped concave groove.
[0012]
Furthermore, the present invention is an antenna element fixed to an arm manufactured by the above method.
[0013]
