Description
本発明は、車体のルーフ等にアンテナベースを取り付けるアンテナ取付装置に関するものである。 The present invention relates to an antenna attachment device for attaching an antenna base to a roof or the like of a vehicle body.
自動車用アンテナ装置を車体のルーフ等に取り付ける従来のアンテナ取付装置の構造は、ルーフ等に穿設した取付孔に、自動車用アンテナ装置のアンテナベースから下方に突出する取付ネジを挿通し、ルーフ等の下方に突出した取付ネジに対して、下方から爪付きワッシャを嵌挿し、さらにナットを螺合して固定するものである。そこで、作業性を良くするために、爪付きワッシャとナットがネジ軸回りに相対回転可能でしかもネジ軸方向に離さないように連結することで一体化されていた。さらに、作業性を向上させる目的で、特許第２７５１１４６号により、取付ネジに爪付きワッシャを介してナットを仮止めする技術が提案されている。この提案技術によれば、仮止め後は、作業者がナットから手を離しても取付ネジからナットが脱落することがなく作業性が改善される。
上記の特許第２７５１１４６号で提案された技術は、取付ネジにナットを仮止めした後は、ナットから作業者が手を離してもナットが脱落せず、作業性に優れたものである。しかしながら、ナットを締め付けた際に、爪付きワッシャの係止爪がルーフ等の裏面に下方から強く押し付けられて食い込むだけであり、ルーフ等の裏面の塗装膜等を必ずしも除去し得るものでない。そこで、ルーフ等と爪付きワッシャの電気的接続が不確実であり、アンテナベースをルーフ等に確実に電気的接続できるものでない。 The technique proposed in the above-mentioned Japanese Patent No. 2751146 is excellent in workability because the nut does not fall off even if the operator removes the hand from the nut after the nut is temporarily fixed to the mounting screw. However, when the nut is tightened, the locking claw of the washer with the claw is merely pressed against the back surface of the roof or the like from below, and the coating film or the like on the back surface of the roof or the like cannot always be removed. Therefore, the electrical connection between the roof or the like and the washer with the claw is uncertain, and the antenna base cannot be reliably electrically connected to the roof or the like.
本発明は、上述のごとき事情に鑑みてなされたもので、ルーフ等にアンテナベースを確実に電気的接続できるアンテナ取付装置を提供することを目的とする。 The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide an antenna mounting apparatus capable of reliably electrically connecting an antenna base to a roof or the like.
かかる目的を達成するために、本発明のアンテナ取付装置は、導電金属板で形成される係止部材に頭部付きの導電金属で形成される取付ネジを嵌挿し、導電金属で形成されるアンテナベースに下方から前記取付ネジの先端部を螺入し、前記係止部材は、平面から見て一部が開口された略Ｃ字状であるとともに上縁部から上方に向けて係止爪を突出し、前記取付ネジの締め付け螺入により前記係止部材の前記開口を拡げる開口機構を設け、前記係止部材が前記開口を拡げた状態となることにより前記係止爪の外径が拡がるように構成されている。 In order to achieve such an object, an antenna mounting device of the present invention is an antenna formed of a conductive metal by fitting a mounting screw formed of a conductive metal with a head into a locking member formed of a conductive metal plate. The tip of the mounting screw is screwed into the base from below, and the locking member is substantially C-shaped with a part opened as viewed from above, and the locking claw is directed upward from the upper edge. An opening mechanism that protrudes and widens the opening of the locking member by tightening the mounting screw is provided so that the outer diameter of the locking claw is expanded when the locking member is in a state of expanding the opening. It is configured.
また、導電金属で形成されるアンテナベースから下方に取付ネジを突設し、前記取付ネジに導電金属板で形成される係止部材を嵌挿し、さらに前記取付ネジの下端部にナットを螺合し、前記係止部材は、平面から見て一部が開口された略Ｃ字状であるとともに上縁部から上方に向けて係止爪を突出し、前記ナットの締め付け螺合により前記係止部材の前記開口を拡げる開口機構を設け、前記係止部材が前記開口を拡げた状態となることにより前記係止爪の外径が拡がるように構成しても良い。 Also, a mounting screw is projected downward from the antenna base made of conductive metal, a locking member formed of a conductive metal plate is fitted into the mounting screw, and a nut is screwed onto the lower end of the mounting screw. The locking member is substantially C-shaped with a part opened as viewed from above, and projects a locking claw upward from the upper edge, and the locking member is tightened and screwed into the locking member. An opening mechanism for expanding the opening may be provided so that the outer diameter of the locking claw is expanded when the locking member is in a state of expanding the opening.
そして、前記係止爪の外径を車体に穿設した取付孔に挿通できるように設定し、前記取付ネジまたはナットの締め付け螺合により前記係止部材が前記開口を拡げた状態となることにより前記係止爪の外径が拡がって前記取付孔の周縁部に臨むように構成することもできる。 Then, the outer diameter of the locking claw is set so that it can be inserted into a mounting hole formed in the vehicle body, and the locking member is in a state where the opening is expanded by tightening the mounting screw or the nut. The outer diameter of the locking claw may be widened so as to face the peripheral edge of the mounting hole.

FIG. 13 shows a nut, (a) is a front view, and (b) is a bottom view. FIG. 14 is a front view showing a state before an antenna base integrated with a locking member and a nut is inserted into a mounting hole such as a roof. FIG. 15 is a front view showing a state of being fastened and fixed to a roof or the like. 12 to 15, the same or equivalent members as those in FIGS. 1 to 7 are denoted by the same reference numerals and redundant description is omitted.
図１２に示すアンテナベース５０で、図２に示すアンテナベース１０と相違するところは、雌ネジ１０ｃを螺切するのに代えて、アンテナベース５０から下方に取付ネジ５０ａを突設したことにある。そして、図１３に示すナット５２は、平面六角形の頭部５２ａと、フランジ部５２ｂおよび円錐台部５２ｃで構成され、中央上下方向に取付ネジ５０ａに螺合し得る雌ネジ５２ｄが螺切されている。ナット５２の円錐台部５２ｃの上部外径は、係止部材２０の下部内径より小さく、下部外径は係止部材２０の下部内径より大きく設定される。なお、第２実施例では、第１実施例と同じ係止部材２０が用いられる。 The antenna base 50 shown in FIG. 12 is different from the antenna base 10 shown in FIG. 2 in that a mounting screw 50a protrudes downward from the antenna base 50 instead of screwing the female screw 10c. . 13 includes a flat hexagonal head 52a, a flange portion 52b, and a truncated cone portion 52c, and a female screw 52d that can be screwed into the mounting screw 50a is threaded in the central vertical direction. ing. The upper outer diameter of the truncated cone portion 52 c of the nut 52 is set smaller than the lower inner diameter of the locking member 20, and the lower outer diameter is set larger than the lower inner diameter of the locking member 20. In the second embodiment, the same locking member 20 as in the first embodiment is used.
そして、アンテナベース５０に係止部材２０とナット５２を組み付けて一体とし、図１４に示すごとく、ルーフ等の取付孔２４に上方からケーブル２２を挿通し、この状態から強く下方に押し込む。すると、係止部材２０の仮止め爪２０ｃ，２０ｃは弾性変形して挿通が許容され、取付孔２４を通過すると弾性復帰し、取付孔２４から上方への抜けが規制されて、仮止め状態となる。そして、下方に突出した状態にあるナット５２を強く締め付けると、図１５に示すごとく、係止部材２０はその径を大きく変形させ、係止爪２０ｂ，２０ｂ…がルーフ等の裏側で取付孔２４の周縁部に拡がりつつ食い込み固定されるとともに電気的接続される。 Then, the locking member 20 and the nut 52 are assembled and integrated with the antenna base 50, and as shown in FIG. 14, the cable 22 is inserted into the mounting hole 24 of the roof or the like from the upper side, and is pushed strongly downward from this state. Then, the temporary fixing claws 20c, 20c of the locking member 20 are elastically deformed and allowed to be inserted, and elastically return when passing through the mounting hole 24. Become. When the nut 52 protruding downward is strongly tightened, as shown in FIG. 15, the locking member 20 greatly deforms its diameter, and the locking claws 20b, 20b... While being spread and fixed to the peripheral portion of the rim, it is electrically connected.
なお、第２実施例にあっても、第１実施例と同様に係止部材２０の開口を拡げる開口機構を適宜に変更しても良い。そして、ナット５２の頭部５２ａを省いて平面六角形の有底孔を穿設し、またナット５２の頭部５２ａと円錐台部５２ｃとを分離する等の変更をすることもできる。 Even in the second embodiment, the opening mechanism for expanding the opening of the locking member 20 may be appropriately changed as in the first embodiment. Further, it is possible to make a change such as removing the head portion 52a of the nut 52 and drilling a flat hexagonal bottomed hole and separating the head portion 52a and the truncated cone portion 52c of the nut 52.
そして、上記実施例では、係止部材２０の仮止め爪２０ｃ，２０ｃは２本設けているが、これに限られず、２本以上設けられれば良い。そして、ルーフ等に穿設される取付孔２４は、略正方形に限られず、円形や楕円形であっても良い。この場合には、アンテナベース１０の凸部１０ａは、取付孔２４に嵌挿し得る形状であることは勿論である。 And in the said Example, although the temporary fix claws 20c and 20c of the latching member 20 are provided, it is not restricted to this, What is necessary is just to provide two or more. And the attachment hole 24 drilled in a roof etc. is not restricted to a substantially square shape, A round shape and an ellipse may be sufficient. In this case, it goes without saying that the convex portion 10 a of the antenna base 10 has a shape that can be fitted into the mounting hole 24.
