Description

本発明は、アンテナ装置に関する。   The present invention relates to an antenna device.

特許文献１は、零相変流器を開示する。この零相変流器は、コアピースと、このコアピースに巻回された二次巻線と、この二次巻線の端末をからげるための端末接合端子と、を有する。   Patent Document 1 discloses a zero-phase current transformer. The zero-phase current transformer has a core piece, a secondary winding wound around the core piece, and a terminal junction terminal for tangling the end of the secondary winding.

特開２０００−３４８９５７号公報（要約、特許請求の範囲、段落００２５など）JP 2000-348957 A (abstract, claims, paragraph 0025, etc.)

特許文献１にあるようにコアピースなどに巻き付けられる巻線の端末は、端末接合端子などと呼ばれる絡げ端子に絡げられる。これにより、巻線は、他の電子部品と電気的に接続可能な状態になる。   As described in Patent Document 1, a terminal of a winding wound around a core piece or the like is wound around a binding terminal called a terminal joining terminal. As a result, the winding is in a state where it can be electrically connected to other electronic components.

しかしながら、このようにコアピースなどに巻き付けられる巻線の端末を、絡げ端子にからげて接続する場合、その巻線の一部がたとえばコアピースなどのつば部より外側へ飛び出し、所謂空中配線部を形成してしまうことがある。   However, when the end of the winding wound around the core piece or the like is connected to the tangled terminal, the part of the winding protrudes outside the collar portion of the core piece or the like, and the so-called aerial wiring portion is formed. May form.

そして、巻線に、コアピースなどのつば部などより外側へ飛び出した空中配線部が形成されてしまうと、たとえば車両のキーレスエントリシステムで使用されるアンテナ装置などにあっては、その空中配線部およびその周囲において、巻線の断線が生じてしまう可能性が高くなる。アンテナ装置に加えられる振動や熱などにより、巻線の空中配線部およびその周囲の部分がつば部の縁へ繰り返し当たり、巻線が断線しやすくなってしまう。   Then, when an aerial wiring portion that protrudes outward from the flange portion of the core piece or the like is formed in the winding, for example, in an antenna device used in a vehicle keyless entry system, the aerial wiring portion and There is a high possibility that the winding breaks around the periphery. Due to vibration or heat applied to the antenna device, the aerial wiring portion of the winding and the surrounding portion repeatedly hit the edge of the collar portion, and the winding tends to be disconnected.

巻線に空中配線部が形成されることに起因する断線が生じ難くなるように、従来のアンテナ装置では、たとえば巻線の中の、空中配線部が形成される危惧がある部位を折り返してより線構造として強度を向上させたり、巻線の中の、空中配線部となる危惧がある部位に接着剤（処理剤）を塗布して固定したりしている。しかしながら、巻線を折り返してより線構造とするためには、そのより線を形成するための複雑な作業工程を追加する必要がある。また、接着剤（処理剤）を塗布するためには、その塗布および乾燥硬化のための工程を追加する必要がある。１つ１つのアンテナ装置に対してそれらの対策を施す場合、アンテナ装置の製造コストが一般的なコイル素子の製造コストに比べて上昇してしまう。   In the conventional antenna device, for example, by folding a part of the winding where there is a risk of formation of the aerial wiring part so that disconnection due to the formation of the aerial wiring part in the winding is less likely to occur. As a wire structure, the strength is improved, or an adhesive (treatment agent) is applied and fixed to a portion of the winding that is likely to become an aerial wiring portion. However, in order to wrap the winding into a more wire structure, it is necessary to add a complicated operation process for forming the wire. Moreover, in order to apply | coat an adhesive agent (processing agent), it is necessary to add the process for the application | coating and dry hardening. When these countermeasures are taken for each antenna device, the manufacturing cost of the antenna device increases as compared with the manufacturing cost of a general coil element.

本願発明者は、このようなアンテナ装置における問題に鑑み、以下の考察をした。そして、本願発明を完成するに至った。   The inventor of the present application has considered the following in view of the problem in such an antenna device. And it came to complete this invention.

図１０は、従来のアンテナ装置における巻線の巻き方の種類の説明図である。図１０（Ａ）〜（Ｄ）の４種類のアンテナ装置の巻線用部品は、円柱形状の巻軸部４１と、円板形状を有し、巻軸部４１の軸方向両端に配設される一対のつば部４２と、を有する。また、一対の絡げ端子４３は、互いに平行となる姿勢で、つば部４２に配設される。   FIG. 10 is an explanatory diagram of the types of winding of the conventional antenna device. Winding parts of the four types of antenna devices shown in FIGS. 10A to 10D have a cylindrical winding shaft portion 41 and a disk shape, and are disposed at both ends of the winding shaft portion 41 in the axial direction. A pair of collar portions 42. Further, the pair of binding terminals 43 are disposed on the collar portion 42 in a posture that is parallel to each other.

図１０（Ａ）では、一対の絡げ端子４３は、つば部４２の同一側に配設される。通常、一対の絡げ端子４３は、巻軸部４１を基準として９０度以下の角度となる位置において、つば部４２に配設される。また、巻線４４は、テンションをかけながら、まず、左上のスタート側の絡げ端子４３に絡げられ、次に、巻軸部４１に反時計周りで巻きつけられ、最後に、右上のフィニッシュ側の絡げ端子４３に絡げられる。この図１０（Ａ）の場合、巻線４４は、スタート側の絡げ端子４３に絡げられる部位と、巻軸部４１に巻きつけられる部位との間の部位（以下、スタート側の巻線４４の引出部位４５と呼ぶ）において、つば部４２より外側へ飛び出した空中配線部を形成してしまうことはない。また、巻線４４は、巻軸部４１に巻きつけられる部位と、フィニッシュ側の絡げ端子４３に絡げられる部位との間の部位（以下、フィニッシュ側の巻線４４の引出部位４６と呼ぶ）において、つば部４２より外側へ飛び出した空中配線部を形成してしまうことはない。   In FIG. 10A, the pair of binding terminals 43 are disposed on the same side of the collar portion 42. Usually, the pair of binding terminals 43 are disposed on the collar portion 42 at a position where the angle is 90 degrees or less with respect to the winding shaft portion 41. In addition, while applying tension, the winding 44 is first wound around the binding terminal 43 on the upper left start side, then wound around the winding shaft portion 41 counterclockwise, and finally, the upper right finish It is bound to the binding terminal 43 on the side. In the case of FIG. 10A, the winding 44 is a portion between the portion wound around the start side binding terminal 43 and the portion wound around the winding shaft portion 41 (hereinafter referred to as start side winding). 44), an aerial wiring portion that protrudes outward from the collar portion 42 is not formed. Further, the winding 44 is a portion between a portion wound around the winding shaft portion 41 and a portion entangled with the binding terminal 43 on the finish side (hereinafter referred to as a drawing portion 46 of the winding 44 on the finish side). ), An aerial wiring portion that protrudes outward from the collar portion 42 is not formed.

図１０（Ｂ）では、一対の絡げ端子４３は、図１０（Ａ）と同様に、つば部４２の同一側に配設される。また、巻線４４は、テンションをかけながら、まず、左上のスタート側の絡げ端子４３に絡げられ、次に、巻軸部４１に時計周りで巻きつけられ、最後に、右上のフィニッシュ側の絡げ端子４３に絡げられる。この図１０（Ｂ）の場合、巻線４４は、スタート側の巻線４４の引出部位４５において、たとえば巻軸部４１がスタート側の絡げ端子４３の根元より図において上側となるほどに大径である場合に空中配線部を形成してしまう。また、巻線４４は、フィニッシュ側の巻線４４の引出部位４６において、大抵の場合に空中配線部を形成してしまう。   In FIG. 10B, the pair of binding terminals 43 are disposed on the same side of the collar portion 42 as in FIG. In addition, while applying tension, the winding 44 is first wound around the binding terminal 43 on the upper left start side, then wound around the winding shaft portion 41 in the clockwise direction, and finally the upper right finish side. It is entangled with the tangling terminal 43. In the case of FIG. 10B, the winding 44 has a large diameter so that, for example, the winding shaft portion 41 is on the upper side in the drawing from the root of the start-side binding terminal 43 at the lead-out portion 45 of the start-side winding 44. In this case, an aerial wiring portion is formed. Further, the winding 44 forms an aerial wiring portion in most cases at the lead-out portion 46 of the winding 44 on the finish side.

図１０（Ｃ）では、一対の絡げ端子４３は、つば部４２の反対側に配設される。具体的には、一対の絡げ端子４３は、巻軸部４１を間に挟み対向する反対側の位置において、つば部４２に配設される。また、巻線４４は、テンションをかけながら、まず、左上のスタート側の絡げ端子４３に絡げられ、次に、巻軸部４１に反時計周りで巻きつけられ、最後に、右下のフィニッシュ側の絡げ端子４３に絡げられる。この図１０（Ｃ）の場合、巻線４４は、スタート側の巻線４４の引出部位４５において、空中配線部を形成してしまうことはない。また、巻線４４は、フィニッシュ側の巻線４４の引出部位４６において、大抵の場合に空中配線部を形成してしまう。   In FIG. 10C, the pair of binding terminals 43 are disposed on the opposite side of the collar portion 42. Specifically, the pair of binding terminals 43 are disposed on the collar portion 42 at positions opposite to each other with the winding shaft portion 41 interposed therebetween. In addition, while applying tension, the winding 44 is first wound around the binding terminal 43 on the upper left start side, then wound around the winding shaft portion 41 counterclockwise, and finally the lower right It is tied to the binding terminal 43 on the finish side. In the case of FIG. 10C, the winding 44 does not form an aerial wiring portion in the lead-out portion 45 of the start-side winding 44. Further, the winding 44 forms an aerial wiring portion in most cases at the lead-out portion 46 of the winding 44 on the finish side.

図１０（Ｄ）では、一対の絡げ端子４３は、図１０（Ｃ）と同様に、つば部４２の反対側に配設される。また、巻線４４は、テンションをかけながら、まず、左上のスタート側の絡げ端子４３に絡げられ、次に、巻軸部４１に時計周りで巻きつけられ、最後に、右下のフィニッシュ側の絡げ端子４３に絡げられる。この図１０（Ｄ）の場合、巻線４４は、スタート側の巻線４４の引出部位４５において、たとえば巻軸部４１がスタート側の絡げ端子４３の根元より図において上側となるほどに大径である場合に空中配線部を形成してしまう。また、巻線４４は、フィニッシュ側の巻線４４の引出部位４６において、空中配線部を形成してしまうことはない。   In FIG. 10D, the pair of binding terminals 43 are disposed on the opposite side of the collar portion 42 as in FIG. In addition, while applying tension, the winding 44 is first wound around the binding terminal 43 on the upper left start side, then wound around the winding shaft portion 41 in the clockwise direction, and finally the lower right finish. It is bound to the binding terminal 43 on the side. In the case of FIG. 10D, the winding 44 has a large diameter so that, for example, the winding shaft portion 41 is on the upper side in the drawing from the root of the start-side binding terminal 43 in the lead-out portion 45 of the start-side winding 44. In this case, an aerial wiring portion is formed. Further, the winding 44 does not form an aerial wiring portion at the lead-out portion 46 of the finish-side winding 44.

この図１０（Ａ）〜（Ｄ）の４つの例に示すように、従来のアンテナ装置では、巻線４４に、つば部４２より外側へ飛び出した空中配線部が形成されてしまう可能性がある。特に、図１０（Ｃ）および（Ｄ）に示すように一対の絡げ端子４３がつば部４２の反対側に配設されている場合、巻軸部４１への巻方向がどちらであったとしても、巻線４４に空中配線部が形成されてしまう。これに対して、一対の絡げ端子４３がつば部４２の同一側に配設されている場合、図１０（Ａ）の巻き方向の場合には、空中配線部が形成されない。しかし、図１０（Ｂ）の場合には、空中配線部が形成される。また、図１０（Ａ）、（Ｂ）の場合には、空中配線の防止のために図１０（Ａ）の方向で巻線４４を巻きつける必要があり、アンテナ装置の製造工程に制約が生じてしまう。このように従来のアンテナ装置において、一対の絡げ端子４３がつば部４２の反対側に配設されている場合には、一対の絡げ端子４３がつば部４２の同一側に配設されている場合に比べて、空中配線部が形成されてしまう可能性が高い。   As shown in the four examples of FIGS. 10A to 10D, in the conventional antenna device, there is a possibility that an aerial wiring portion that protrudes outward from the flange portion 42 is formed in the winding 44. . In particular, as shown in FIGS. 10 (C) and 10 (D), when the pair of binding terminals 43 are disposed on the opposite side of the flange portion 42, the winding direction to the winding shaft portion 41 is either. However, an aerial wiring part is formed in the winding 44. On the other hand, when the pair of binding terminals 43 are disposed on the same side of the collar portion 42, the aerial wiring portion is not formed in the winding direction of FIG. However, in the case of FIG. 10B, an aerial wiring portion is formed. Further, in the case of FIGS. 10A and 10B, it is necessary to wind the winding 44 in the direction of FIG. 10A in order to prevent the aerial wiring, and the manufacturing process of the antenna device is restricted. End up. Thus, in the conventional antenna device, when the pair of binding terminals 43 are disposed on the opposite side of the collar portion 42, the pair of binding terminals 43 are disposed on the same side of the collar portion 42. Compared with the case where there is, there is a high possibility that the aerial wiring portion is formed.

本発明は、巻線を一対の絡げ端子および巻線用部品に巻き付ける際に、巻線に、つば部より外側へ飛び出した空中配線部がほぼ形成されないアンテナ装置を得ることを目的とする。   An object of the present invention is to obtain an antenna device in which an aerial wiring portion that protrudes outward from a flange portion is not substantially formed in a winding when the winding is wound around a pair of binding terminals and a winding component.

本発明に係るアンテナ装置は、略円柱形状の巻軸部、および略円板形状を有し、巻軸部の軸方向の両端部の中の少なくとも一方の端部に配設されて巻軸部より外側へ突出するつば部を有する巻線用部品と、少なくとも１つのつば部に、つば部より外側へ突出して配設される一対の絡げ端子と、一対の絡げ端子に両端が絡げられる巻線と、を有する。そして、一対の絡げ端子の中の少なくとも一方の絡げ端子は、つば部の外周に略垂直な方向に沿った向きで配設される。   The antenna device according to the present invention has a substantially cylindrical winding shaft portion and a substantially disk shape, and is disposed at at least one end of both ends in the axial direction of the winding shaft portion. Winding parts having a flange portion protruding outward, at least one flange portion, a pair of binding terminals protruding outward from the collar portion, and a pair of binding terminals having both ends Windings to be provided. Then, at least one of the pair of binding terminals is disposed in a direction along a direction substantially perpendicular to the outer periphery of the collar portion.

この構成を採用すれば、巻線は、テンションをかけながら一対の絡げ端子に絡げられ、且つ巻軸部に巻き付けられる。これにより、巻線は、巻線の巻軸部に対する巻方向などに関係なく、一対の絡げ端子の根元部分（つば部から突出する根元の部分）に絡げられる。したがって、つば部より外側へ飛び出した空中配線部がほぼ形成されない。   If this structure is employ | adopted, a coil | winding will be wound around a pair of winding terminals, applying a tension | tensile_strength, and it will be wound around a winding shaft part. As a result, the winding is entangled with the root portions of the pair of binding terminals (the root portion protruding from the collar portion) regardless of the winding direction of the winding with respect to the winding shaft portion. Therefore, the aerial wiring portion that protrudes outward from the collar portion is hardly formed.

本発明に係るアンテナ装置は、上述した発明の構成に加えて以下の特徴を有するものである。すなわち、一対の絡げ端子は、巻軸部を間に挟み対向する反対側の位置に、つば部の外周に略垂直な方向に沿った向きで配設されている。   The antenna device according to the present invention has the following features in addition to the above-described configuration of the invention. In other words, the pair of binding terminals are disposed in the direction along the direction substantially perpendicular to the outer periphery of the collar portion at a position on the opposite side across the winding shaft portion.

一対の絡げ端子が巻軸部を間に挟み対向する反対側の位置に配設される場合、従来のアンテナ装置では、空中配線部が形成される可能性が高い。これに対して、この構成のように、一対の絡げ端子を、その反対側の位置において、つば部の外周に略垂直な方向に沿った向きで配設することで、空中配線部が形成されなくなる。巻線は、巻線の巻軸部に対する巻方向などに関係なく、一対の絡げ端子の根元部分（つば部から突出する根元の部分）に絡げられ、つば部より外側へ飛び出した空中配線部が形成されない。   In the case where the pair of binding terminals are disposed at positions opposite to each other with the winding shaft portion interposed therebetween, in the conventional antenna device, there is a high possibility that an aerial wiring portion is formed. On the other hand, as in this configuration, the aerial wiring portion is formed by arranging the pair of binding terminals in the direction along the direction substantially perpendicular to the outer periphery of the collar portion at the opposite position. It will not be done. Winding is entangled at the base part of the pair of tie terminals (the base part protruding from the collar part) regardless of the winding direction with respect to the winding axis part of the winding, and the aerial wiring jumps out of the collar part Part is not formed.

本発明に係るアンテナ装置は、上述した発明の各構成に加えて以下の特徴を有するものである。すなわち、各絡げ端子は、該アンテナ装置を実装するための一対のユーザ端子のいずれかと１対１で一体化されている。また、一対の絡げ端子は、同一のつば部に一対のユーザ端子ととともに配設されている。   The antenna device according to the present invention has the following features in addition to the components of the above-described invention. That is, each binding terminal is integrated with one of a pair of user terminals for mounting the antenna device on a one-to-one basis. Further, the pair of binding terminals are disposed together with the pair of user terminals on the same collar portion.

ユーザ端子と一体化された絡げ端子を共通の１つのつば部に配設する場合、アンテナ装置はこの一対の絡げ端子が配設される側（つまり、ユーザ端子の配設される側）でプリント基板などに実装される。実装時に、一対の絡げ端子およびそれらに絡げられる巻線の両端部は、プリント基板などの他の部材と干渉しやすい。そのため、一般的には、実装状態で一対の絡げ端子が一対のユーザ端子よりプリント基板などから離れるように、一対の絡げ端子などを曲げる必要がある。また、振動などにより巻線がつば部に当たり難くするために、一対の絡げ端子を大きく曲げるのが望ましい。   In the case where the binding terminal integrated with the user terminal is disposed on one common collar portion, the antenna device is on the side where the pair of binding terminals are disposed (that is, the side where the user terminal is disposed). It is mounted on a printed circuit board. At the time of mounting, the pair of binding terminals and both ends of the windings connected to them tend to interfere with other members such as a printed circuit board. Therefore, in general, it is necessary to bend the pair of binding terminals and the like so that the pair of binding terminals are separated from the printed circuit board and the like from the pair of user terminals in the mounted state. In addition, it is desirable that the pair of tangled terminals be greatly bent so that the winding does not easily hit the collar portion due to vibration or the like.

これに対して、この構成を採用すれば、巻線は、絡げ端子の根元に絡げられ、空中配線部が形成され難い。したがって、断線の可能性を低くするために、一対の絡げ端子などを大きく曲げる必要は無い。一対の絡げ端子などは、プリント基板などの他の部材と干渉し難い程度に軽く曲げればよい。したがって、一対の絡げ端子および一対のユーザ端子を、樹脂モールド成形時にインサート成形することにより精度良く位置決めして、且つ、容易に、つば部に配設することができる。   On the other hand, if this configuration is adopted, the winding is entangled at the base of the tying terminal, and the aerial wiring portion is hardly formed. Therefore, in order to reduce the possibility of disconnection, it is not necessary to greatly bend the pair of binding terminals. The pair of binding terminals may be bent lightly to such an extent that they do not easily interfere with other members such as a printed circuit board. Therefore, the pair of binding terminals and the pair of user terminals can be accurately positioned by insert molding at the time of resin molding, and can be easily disposed on the collar portion.

本発明では、巻線を一対の絡げ端子および巻線用部品に巻き付ける際に、つば部より外側へ飛び出した空中配線部が形成されにくくすることができる。   In the present invention, when the winding is wound around the pair of binding terminals and the winding component, it is possible to make it difficult to form an aerial wiring portion that protrudes outward from the collar portion.

以下、本発明の実施の形態に係るアンテナ装置を、図面に基づいて説明する。   Hereinafter, an antenna device according to an embodiment of the present invention will be described with reference to the drawings.

図２は、図１中の巻線用部品２の構成を示す側面図である。巻線用部品２は、円柱形状の巻軸部１０を有する。巻軸部１０の中心には、巻軸部１０の上面から下面までを貫通する、長楕円形状の貫通孔１１が設けられる。   FIG. 2 is a side view showing the configuration of the winding component 2 in FIG. The winding component 2 has a cylindrical winding shaft portion 10. At the center of the winding shaft portion 10, an oblong through hole 11 that penetrates from the upper surface to the lower surface of the winding shaft portion 10 is provided.

巻軸部１０の軸方向の両端部の中の一方の端部（図２では上側の端部）には、つば部としての小径つば部１２が形成される。小径つば部１２は、巻軸部１０より大きい直径の円板状を有する。小径つば部１２は、巻軸部１０より外側へ突出する。   A small-diameter collar portion 12 as a collar portion is formed at one end portion (upper end portion in FIG. 2) of both end portions in the axial direction of the winding shaft portion 10. The small-diameter collar portion 12 has a disk shape with a diameter larger than that of the winding shaft portion 10. The small-diameter collar portion 12 projects outward from the winding shaft portion 10.

巻軸部１０の軸方向の両端部の中の他方の端部（図２では下側の端部）には、つば部としての大径つば部１３が形成される。大径つば部１３は、小径つば部１２より大きい直径の円板状とされる。大径つば部１３は、巻軸部１０より外側へ突出する。また、大径つば部１３は、切欠部１４を有する。この切欠部１４により、大径つば部１３は、断面略Ｄ字形状になる。   A large-diameter collar portion 13 as a collar portion is formed at the other end portion (the lower end portion in FIG. 2) of the axial end portions of the winding shaft portion 10. The large-diameter collar portion 13 has a disk shape with a diameter larger than that of the small-diameter collar portion 12. The large-diameter collar portion 13 projects outward from the winding shaft portion 10. The large-diameter collar portion 13 has a notch portion 14. Due to the cutout portion 14, the large-diameter collar portion 13 has a substantially D-shaped cross section.

小径つば部１２と大径つば部１３とは、巻軸部１０の上下において互いに略平行に配設される。大径つば部１３は、切欠部１４が形成される部位を含めて、小径つば部１２より外側へ突出している。   The small-diameter collar portion 12 and the large-diameter collar portion 13 are disposed substantially parallel to each other above and below the winding shaft portion 10. The large-diameter collar portion 13 protrudes outward from the small-diameter collar portion 12 including the portion where the notch portion 14 is formed.

これら巻軸部１０、小径つば部１２および大径つば部１３により構成される巻線用部品２は、樹脂材料をモールド成形することで一体的に形成される。巻線用部品２の外形は、直径が約１０〜２０ミリメートルであり、厚さが約１〜３ミリメートルである。   The winding component 2 constituted by the winding shaft portion 10, the small-diameter collar portion 12, and the large-diameter collar portion 13 is integrally formed by molding a resin material. The winding component 2 has an outer diameter of about 10 to 20 millimeters and a thickness of about 1 to 3 millimeters.

保護カバー３は、耐熱性のプラスチック材料を円板形状に形成したものである。保護カバー３の直径は、大径つば部１３の直径より一回り小さく、且つ、小径つば部１２の直径より大きい。保護カバー３は、その中心と巻線用部品２の中心とが一致するように、小径つば部１２に重ねて接着される。   The protective cover 3 is formed by forming a heat-resistant plastic material into a disc shape. The diameter of the protective cover 3 is slightly smaller than the diameter of the large-diameter collar portion 13 and larger than the diameter of the small-diameter collar portion 12. The protective cover 3 is adhered to the small-diameter collar portion 12 so that the center thereof coincides with the center of the winding component 2.

図３は、図１中の端子プレート５を示す図である。図３（Ａ）は、端子プレート５の正面図であり、図３（Ｂ）は、端子プレート５の側面図である。図３には、端子プレート５に対する大径つば部１３の縁が点線で示されている。   FIG. 3 is a view showing the terminal plate 5 in FIG. FIG. 3A is a front view of the terminal plate 5, and FIG. 3B is a side view of the terminal plate 5. In FIG. 3, the edge of the large-diameter collar portion 13 with respect to the terminal plate 5 is indicated by a dotted line.

端子プレート５は、ユーザ端子２１と、絡げ端子２２と、を有する。ユーザ端子２１は、アンテナ装置１をプリント基板などに実装するときに、プリント基板にはんだ付けされるものである。絡げ端子２２は、巻線４の端部が絡げて固定されるものである。ユーザ端子２１および絡げ端子２２は、矩形形状、すなわち端子の側面に突起がないストレート形状を有する。矩形形状のユーザ端子２１と、矩形形状の絡げ端子２２とは、それらの先端側同士の間隔が広がった略Ｖ字形状の配置となるように、基端側において連結部材２３により連結される。連結部材２３およびユーザ端子２１の基端側の部位には、複数の貫通孔２４が設けられる。   The terminal plate 5 includes a user terminal 21 and a binding terminal 22. The user terminal 21 is soldered to the printed board when the antenna device 1 is mounted on the printed board or the like. The binding terminal 22 is fixed by binding the end of the winding 4. The user terminal 21 and the binding terminal 22 have a rectangular shape, that is, a straight shape having no protrusion on the side surface of the terminal. The rectangular user terminal 21 and the rectangular binding terminal 22 are connected by the connecting member 23 on the base end side so as to have a substantially V-shaped arrangement in which the distance between the distal end sides is widened. . A plurality of through holes 24 are provided in the proximal end portions of the connecting member 23 and the user terminal 21.

ユーザ端子２１、絡げ端子２２および連結部材２３により構成される端子プレート５は、電子部品の端子などに用いられる薄い金属板をプレス加工により打ち抜くことで一体的に形成される。端子プレート５の板厚は、約０．１〜１ミリメートルである。図３（Ｂ）の側面図に示すように、絡げ端子２２の先端部は、巻線用部品２側へ少しだけ曲げられる。これにより、アンテナ装置１をプリント基板などに実装したとき、絡げ端子２２の先端は、プリント基板の表面から若干浮く。   The terminal plate 5 constituted by the user terminal 21, the binding terminal 22 and the connecting member 23 is integrally formed by punching a thin metal plate used for a terminal of an electronic component or the like by pressing. The plate thickness of the terminal plate 5 is about 0.1 to 1 millimeter. As shown in the side view of FIG. 3B, the tip of the binding terminal 22 is bent slightly toward the winding component 2 side. Thereby, when the antenna device 1 is mounted on a printed circuit board or the like, the tip of the binding terminal 22 slightly floats from the surface of the printed circuit board.

一対の端子プレート５は、図１に示すように、巻線用部品２の大径つば部１３に配設される。一対の絡げ端子２２は、大径つば部１３の反対側に配設される。一対のユーザ端子２１は、大径つば部１３の反対側に配設される。つまり、一対の端子プレート５は、一対の絡げ端子２２が巻軸部１０と一直線上に並び、且つ、一対のユーザ端子２１が巻軸部１０と一直線上に並ぶように、巻軸部１０を間に挟む反対側の位置に配設される。   As shown in FIG. 1, the pair of terminal plates 5 are disposed on the large-diameter collar portion 13 of the winding component 2. The pair of binding terminals 22 are disposed on the opposite side of the large-diameter collar portion 13. The pair of user terminals 21 are disposed on the opposite side of the large-diameter collar portion 13. In other words, the pair of terminal plates 5 includes the winding shaft portion 10 such that the pair of binding terminals 22 are aligned with the winding shaft portion 10 and the pair of user terminals 21 are aligned with the winding shaft portion 10. It is arrange | positioned in the position of the other side on both sides of.

また、一対の端子プレート５は、その反対側の位置において、一対の絡げ端子２２および一対のユーザ端子２１が、大径つば部１３および円柱形状の巻軸部１０の外周面に略垂直（垂直方向もしくは、同様の効果を得られるそれに準じた方向）な方向（図１中で一点鎖線で示す方向）に沿った向きとなる姿勢で、すなわち円形の巻線用部品２の中心から放射状に延びる方向に沿った向きとなる姿勢で配設される。   Further, in the pair of terminal plates 5, the pair of binding terminals 22 and the pair of user terminals 21 are substantially perpendicular to the outer peripheral surfaces of the large-diameter collar portion 13 and the cylindrical winding shaft portion 10 ( In a posture that is oriented along a vertical direction or a direction equivalent to that in which a similar effect can be obtained) (direction indicated by a one-dot chain line in FIG. 1), that is, radially from the center of the circular winding component 2 It arrange | positions with the attitude | position used as the direction along the extending direction.

一対の端子プレート５は、たとえば巻線用部品２を樹脂モールドにより成形する際に、成形型枠内でインサート成形することで、巻線用部品２のつば部に配設すればよい。一対の端子プレート５は、貫通孔２４内に樹脂が入り込むことで、巻線用部品２に固定される。インサート成形により一対の端子プレート５を巻線用部品２に配設することで、一対の端子プレート５は、その形状があまり曲がっていない薄い平板形状（簡単な形状）であることも相俟って、大径つば部１３に対して、上述した所望の姿勢および位置に精度良く配設される。   The pair of terminal plates 5 may be disposed on the flange portion of the winding component 2 by insert molding in a molding frame when the winding component 2 is molded by resin molding, for example. The pair of terminal plates 5 are fixed to the winding component 2 by the resin entering the through holes 24. By arranging the pair of terminal plates 5 on the winding component 2 by insert molding, the pair of terminal plates 5 is also a thin flat plate shape (simple shape) that is not bent so much. Thus, the large-diameter collar portion 13 is accurately arranged in the desired posture and position described above.

巻線４は、断面が円形状（丸線形状）あるいは四角形形状（平角形状）のエナメル線である。巻線４の太さは、たとえば０．０３〜０．５ミリメートル程度であればよい。巻線４は、巻軸部１０に巻きつけられる。巻線４の両端部は、エナメル被覆が剥がされた上で、一対の絡げ端子２２に絡げてはんだ付けされる。   The winding 4 is an enameled wire having a circular cross section (round wire shape) or a quadrangular shape (flat rectangular shape). The thickness of the winding 4 may be about 0.03 to 0.5 millimeters, for example. The winding 4 is wound around the winding shaft portion 10. Both ends of the winding 4 are soldered with a pair of binding terminals 22 after the enamel coating is removed.

図４は、図１のアンテナ装置１における巻線４の巻き方を説明するための模式図である。図４（Ａ）は、巻線４を、まず、図の上側の絡げ端子２２に絡げ、次に、巻軸部１０に対して反時計回りに巻き付け、最後に、図の下側の絡げ端子２２に絡げた場合の巻き付けた場合のアンテナ装置１の模式図である。図４（Ｂ）は、巻線４を、まず、図の上側の絡げ端子２２に絡げ、次に、巻軸部１０に対して時計回りに巻き付け、最後に、図の下側の絡げ端子２２に絡げた場合の巻き付けた場合のアンテナ装置１の模式図である。このように、図１のアンテナ装置１では、巻線４は、巻軸部１０に対して２通りの方向で巻くことが可能である。   FIG. 4 is a schematic diagram for explaining how to wind the winding 4 in the antenna device 1 of FIG. 4A, the winding 4 is first wound around the binding terminal 22 on the upper side of the drawing, then wound around the winding shaft portion 10 in the counterclockwise direction, and finally, on the lower side of the drawing. It is the schematic diagram of the antenna apparatus 1 at the time of winding when wound around the binding terminal 22. 4B, the winding 4 is first wound around the binding terminal 22 on the upper side of the drawing, then wound clockwise around the winding shaft portion 10, and finally, the winding on the lower side of the drawing. It is the schematic diagram of the antenna apparatus 1 at the time of winding at the time of being wound around the bent terminal 22. Thus, in the antenna device 1 of FIG. 1, the winding 4 can be wound around the winding shaft portion 10 in two directions.

巻線４は、具体的には、図の上側の絡げ端子２２に絡げた後、巻線用部品２を回転体に固定（チャック）し、その状態で巻線４に引っ張りテンションを加えながら、巻線用部品２および回転体を回転することで、巻軸部１０に巻きつけられる。また、巻線４は、巻線用部品２に巻きつけた後、巻線４に引っ張りテンションを加えながら、図の下側の絡げ端子２２に絡げられてはんだ付けされる。   Specifically, after winding the winding 4 to the binding terminal 22 on the upper side of the drawing, the winding component 2 is fixed (chucked) to the rotating body, and in this state, tension is applied to the winding 4 The winding part 2 and the rotating body are rotated to be wound around the winding shaft part 10. Further, after winding the winding 4 around the winding component 2, the winding 4 is wound around the binding terminal 22 on the lower side of the drawing and soldered while applying a tensile tension to the winding 4.

このように、巻線４に引っ張りテンションを加えながら巻軸部１０に巻き付けたり、巻線４に引っ張りテンションを加えながら絡げ端子２２に絡げるようにしたりすることで、巻線４は、弛むことなく、巻軸部１０および一対の絡げ端子２２に巻きつけられる。巻線４は、整列した状態で、巻軸部１０に巻きつけられる。巻線４は、巻線用部品２に対して、所望の巻数で巻きつけられる。巻線４は、図１（Ｂ）に示すように、巻線用部品２の大径つば部１３と保護カバー３との間の隙間内に、所望の巻数で巻きつけられる。   In this way, the winding 4 is wound around the winding shaft portion 10 while applying a tension to the winding 4, or entangled with the binding terminal 22 while applying a tension to the winding 4. It is wound around the winding shaft part 10 and the pair of binding terminals 22 without slack. The winding 4 is wound around the winding shaft portion 10 in an aligned state. The winding 4 is wound around the winding component 2 with a desired number of turns. As shown in FIG. 1B, the winding 4 is wound with a desired number of turns in the gap between the large-diameter collar portion 13 of the winding component 2 and the protective cover 3.

なお、図３（Ｂ）に示すように、絡げ端子２２の先端は、巻線用部品２側に曲げられている。絡げ端子２２の先端は、アンテナ装置１をプリント基板などに実装したときに、プリント基板の表面から若干浮く。したがって、巻線４が絡げ端子２２の先端部にはんだ付けされた状態で、アンテナ装置１をプリント基板に実装した時、ユーザ端子２１がプリント基板の表面から浮いてしまうことはない。   As shown in FIG. 3B, the tip of the binding terminal 22 is bent toward the winding component 2 side. The tip of the binding terminal 22 slightly floats from the surface of the printed board when the antenna device 1 is mounted on the printed board or the like. Therefore, when the antenna device 1 is mounted on the printed circuit board in a state where the winding 4 is soldered to the tip of the tangled terminal 22, the user terminal 21 does not float from the surface of the printed circuit board.

また、一対の絡げ端子２２は、大径つば部１３において、反対側に配設される。一対の絡げ端子２２は、巻軸部１０を基準として１８０度ずれた一直線となる位置（大径つば部１３において反対側となる位置）に配設される。また、一対の絡げ端子２２は、その反対の位置において、大径つば部１３および巻軸部１０の外周面に略垂直な方向に沿った向きとなる姿勢で配設される。   Further, the pair of binding terminals 22 are disposed on the opposite side in the large-diameter collar portion 13. The pair of binding terminals 22 is disposed at a position that is a straight line that is shifted by 180 degrees with respect to the winding shaft portion 10 (a position that is opposite to the large-diameter collar portion 13). In addition, the pair of binding terminals 22 are disposed in the opposite positions so as to be oriented along a direction substantially perpendicular to the outer peripheral surfaces of the large-diameter collar portion 13 and the winding shaft portion 10.

したがって、引っ張りテンションを加えながら巻線４を一対の絡げ端子２２および巻軸部１０に巻きつけると、巻線４は、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。図４に示すように、巻線４は、巻線４の巻軸部１０に対する巻方向に関係なく、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。   Therefore, when the winding 4 is wound around the pair of binding terminals 22 and the winding shaft portion 10 while applying a tensile tension, the winding 4 protrudes from the root portion of the pair of binding terminals 22 (the large-diameter collar portion 13). The root part). As shown in FIG. 4, the winding 4 is provided at the root portion of the pair of binding terminals 22 (the root portion protruding from the large-diameter collar portion 13) regardless of the winding direction of the winding 4 with respect to the winding shaft portion 10. It is tied.

また、巻線４は、図５に示すように、巻軸部１０の径が大きい場合でも、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。図５は、図１のアンテナ装置１より巻軸部１０が大径化されているアンテナ装置１における、巻線４の巻き方を説明するための模式図である。   In addition, as shown in FIG. 5, the winding 4 is entangled with the root portions of the pair of binding terminals 22 (the root portion protruding from the large-diameter collar portion 13) even when the diameter of the winding shaft portion 10 is large. It is done. FIG. 5 is a schematic diagram for explaining how to wind the winding 4 in the antenna device 1 in which the winding shaft portion 10 has a larger diameter than the antenna device 1 of FIG.

その結果、この実施の形態１のアンテナ装置１では、巻線４は、巻軸部１０に対する巻線４の巻方向や、巻軸部１０の径の大きさに関係なく、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。巻線４には、巻軸部１０に対する巻方向や巻軸部１０の径の大きさに関係なく、巻線４のスタート側の引出部位およびフィニッシュ側の引出部位に、空中配線部が形成されることはない。   As a result, in the antenna device 1 according to the first embodiment, the winding 4 has a pair of binding terminals regardless of the winding direction of the winding 4 with respect to the winding shaft portion 10 and the diameter of the winding shaft portion 10. 22 is entangled with the root portion (the root portion protruding from the large-diameter collar portion 13). In the winding 4, an aerial wiring portion is formed at the start-side drawing portion and the finish-side drawing portion of the winding 4 regardless of the winding direction with respect to the winding shaft portion 10 and the diameter of the winding shaft portion 10. Never happen.

図６は、比較例のアンテナ装置１における端子プレート３１の正面図である。この比較例の端子プレート３１は、矩形形状のユーザ端子２１と、矩形形状の側面に一対の突起部３２が形成された絡げ端子３３と、を有する。そして、ユーザ端子２１と絡げ端子３３とは、略平行な配置となるように連結部材２３により連結される。図６には、比較例の端子プレート３１に対する大径つば部１３の縁が点線で示されている。比較例の端子プレート３１は、一対の突起部３２が大径つば部１３の外周縁に沿うように位置決めされて、大径つば部１３に配設される。   FIG. 6 is a front view of the terminal plate 31 in the antenna device 1 of the comparative example. The terminal plate 31 of this comparative example includes a rectangular user terminal 21 and a binding terminal 33 having a pair of protrusions 32 formed on a rectangular side surface. And the user terminal 21 and the binding terminal 33 are connected by the connection member 23 so that it may become a substantially parallel arrangement | positioning. In FIG. 6, the edge of the large-diameter collar portion 13 with respect to the terminal plate 31 of the comparative example is indicated by a dotted line. The terminal plate 31 of the comparative example is positioned on the large-diameter collar 13 such that the pair of protrusions 32 are positioned along the outer peripheral edge of the large-diameter collar 13.

この図６の比較例の端子プレート３１では、巻線４を絡げ端子３３にからげるとき、巻線４は、一対の突起部３２に引っかかる。巻線４は、一対の突起部３２より絡げ端子３３の先端側へずれない。したがって、巻線４は、一対の突起部３２より内側の、一対の絡げ端子３３の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。巻線４には、巻軸部１０に対する巻方向や巻軸部１０の径の大きさに関係なく、巻線４のスタート側の引出部位およびフィニッシュ側の引出部位に、空中配線部が形成され難くなる。   In the terminal plate 31 of the comparative example of FIG. 6, when the winding 4 is entangled with the terminal 33, the winding 4 is caught by the pair of protrusions 32. The winding 4 is not displaced from the pair of protrusions 32 toward the distal end side of the binding terminal 33. Therefore, the winding 4 is entangled with the root portions of the pair of binding terminals 33 (the root portions protruding from the large-diameter collar portion 13) inside the pair of protrusions 32. In the winding 4, an aerial wiring portion is formed at the start-side drawing portion and the finish-side drawing portion of the winding 4 regardless of the winding direction with respect to the winding shaft portion 10 and the diameter of the winding shaft portion 10. It becomes difficult.

しかしながら、図６の比較例の端子プレート５は、大径つば部１３の縁に対する位置精度として極めて高いものが要求される。一対の突起部３２に巻線４を引っ掛けることで、巻線４が一対の絡げ端子３３の根元部分（大径つば部１３から突出する根元の部分）に絡げられるようにするためには、一対の突起部３２は、大径つば部１３の外周縁に隣接する位置に精度良く配設される必要がある。一対の突起部３２が大径つば部１３の外周縁から離れて配設されてしまうと、巻線４は、一対の絡げ端子３３の根元部分より先端側よりに絡げられてしまうようになる。巻線４には、空中配線部が形成されてしまう可能性が生じる。したがって、この図６の比較例の端子プレート５では、大径つば部１３の外周縁に対する位置あわせ作業が大変である。インサート成形により、比較例の端子プレート３１を十分な精度で大径つば部１３に配設することは難しい。   However, the terminal plate 5 of the comparative example of FIG. 6 is required to have extremely high positional accuracy with respect to the edge of the large-diameter collar portion 13. In order to hook the winding 4 to the pair of protrusions 32 so that the winding 4 is entangled with the root portion of the pair of binding terminals 33 (the root portion protruding from the large-diameter collar portion 13). The pair of protrusions 32 need to be accurately arranged at positions adjacent to the outer peripheral edge of the large-diameter collar portion 13. If the pair of protrusions 32 are arranged away from the outer peripheral edge of the large-diameter collar portion 13, the winding 4 is entangled from the root portion of the pair of binding terminals 33 from the tip side. Become. The winding 4 may be formed with an aerial wiring portion. Therefore, in the terminal plate 5 of the comparative example of FIG. 6, the alignment work with respect to the outer peripheral edge of the large-diameter collar portion 13 is difficult. It is difficult to arrange the terminal plate 31 of the comparative example on the large-diameter collar portion 13 with sufficient accuracy by insert molding.

これに対して、この実施の形態のように、絡げ端子２２を単なる矩形形状（ストレート形状）とし、且つ、この矩形形状（ストレート形状）の絡げ端子２２に巻線４を絡げるようにする場合には、絡げ端子２２の、大径つば部１３の縁に対する位置精度が高くない場合であっても、巻線４は、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）にしっかりと絡げられる。巻線４は、絡げ端子２２の先端側へずれて絡げられてしまうことはない。この実施の形態の矩形形状の絡げ端子２２では、大径つば部１３の外周縁に対する位置精度として、高い位置精度は要求されない。   On the other hand, as in this embodiment, the binding terminal 22 has a simple rectangular shape (straight shape), and the winding 4 is wound around the rectangular shape (straight shape) binding terminal 22. In this case, even if the position accuracy of the binding terminal 22 with respect to the edge of the large-diameter collar portion 13 is not high, the winding 4 is connected to the root portion of the pair of binding terminals 22 (large-diameter collar portion). The root part protruding from 13) is tightly entangled. The winding 4 is not entangled by being shifted to the tip end side of the tying terminal 22. In the rectangular binding terminal 22 of this embodiment, high positional accuracy is not required as positional accuracy with respect to the outer peripheral edge of the large-diameter collar portion 13.

以上のように、この実施の形態によれば、大径つば部１３に、ユーザ端子２１および絡げ端子２２を有する一対の端子プレート５が、配設される。この一対の絡げ端子２２は、巻軸部１０と一直線上に並ぶように巻軸部１０を間に挟む反対側の位置において、大径つば部１３および巻軸部１０の外周面に略垂直な方向に沿った向きで、すなわち巻線用部品２の中心から放射状に延びる方向に沿った向きで配設される。   As described above, according to this embodiment, the pair of terminal plates 5 having the user terminals 21 and the binding terminals 22 are disposed on the large-diameter collar portion 13. The pair of binding terminals 22 are substantially perpendicular to the outer peripheral surfaces of the large-diameter collar portion 13 and the winding shaft portion 10 at a position opposite to the winding shaft portion 10 so as to be aligned with the winding shaft portion 10. In the direction along the vertical direction, that is, in the direction along the direction extending radially from the center of the winding component 2.

したがって、巻線４は、テンションをかけながら一対の絡げ端子２２に絡げられたとき、テンションにより引っ張られて一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。巻線４は、巻線４の巻軸部１０に対する巻方向などに関係なく、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。したがって、巻線４には、大径つば部１３の外周縁より外側へ飛び出した空中配線部が形成されない。巻線４のスタート側の引出部位およびフィニッシュ側の引出部位に、空中配線部が形成されることはない。   Accordingly, when the winding 4 is entangled with the pair of tying terminals 22 while applying tension, the winding 4 is pulled by the tension and the base part of the pair of tying terminals 22 (the part of the base protruding from the large-diameter collar part 13). ). Regardless of the winding direction of the winding 4 with respect to the winding shaft portion 10, the winding 4 is entangled with the root portions of the pair of binding terminals 22 (the root portion protruding from the large-diameter collar portion 13). Therefore, the winding 4 does not have an aerial wiring portion that protrudes outward from the outer peripheral edge of the large-diameter collar portion 13. An aerial wiring portion is not formed at the start-side drawing portion and the finish-side drawing portion of the winding 4.

なお、従来のアンテナ装置１では、発明が解決しようとする課題の欄において説明したように、一対の絡げ端子２２は巻軸部１０を間に挟み対向する反対側の位置に配設される場合、空中配線部が形成されてしまう可能性が高い。   In the conventional antenna device 1, as described in the section of the problem to be solved by the invention, the pair of binding terminals 22 are disposed at positions opposite to each other with the winding shaft portion 10 interposed therebetween. In such a case, there is a high possibility that an aerial wiring portion is formed.

その結果、この実施の形態のアンテナ装置１では、車両のキーレスエントリシステムなどで使用されて振動や熱などが加えられたとしても、巻線４のスタート側の引出部位およびフィニッシュ側の引出部位が、つば部の縁に繰り返し当たってしまうことはない。巻線４は、断線し難い。また、巻線４のスタート側の引出部位およびフィニッシュ側の引出部位をより線構造としたり、接着剤で固定したりしなくとも、巻線４が断線し難くなる。   As a result, in the antenna device 1 according to this embodiment, even if vibration or heat is applied to the vehicle keyless entry system or the like, the lead-out part on the start side and the lead-out part on the finish side of the winding 4 are , It will not hit the edge of the collar part repeatedly. Winding 4 is hard to break. Further, the winding 4 is difficult to be disconnected even if the lead-out portion and the finish-out portion of the winding 4 are not formed in a twisted wire structure or fixed with an adhesive.

また、この実施の形態のアンテナ装置１は、巻線４の引出部位の断線を防ぐための、より線工程や接着工程などが不要であり、それらの工程による工程数の増加やコストアップを招くことはない。この実施の形態のアンテナ装置１は、巻線４を用いた他のコイル素子と同様の工程数およびコストにより形成することが可能となる。   Further, the antenna device 1 according to this embodiment does not require a stranded process or an adhesion process for preventing disconnection of the lead-out portion of the winding 4, and causes an increase in the number of processes and an increase in cost due to these processes. There is nothing. The antenna device 1 of this embodiment can be formed with the same number of steps and cost as other coil elements using the winding 4.

また、この実施の形態では、絡げ端子２２は、アンテナ装置１を実装するためのユーザ端子２１と１対１で一体化されている。また、一対の絡げ端子２２は、一対のユーザ端子２１ととともに、大径つば部１３に共通に配設されている。   In this embodiment, the binding terminal 22 is integrated with the user terminal 21 for mounting the antenna device 1 on a one-to-one basis. The pair of binding terminals 22 is disposed in common with the large-diameter collar portion 13 together with the pair of user terminals 21.

ユーザ端子２１と一体化された一対の絡げ端子２２を、大径つば部１３などの同一のつば部に配設する場合、アンテナ装置はこの一対の絡げ端子２２が配設される側でプリント基板などに実装される。実装時に、一対の絡げ端子２２およびそれらに絡げられる巻線４の両端部は、プリント基板などの他の部材と干渉しやすい。そのため、一般的には、実装状態で一対の絡げ端子２２が一対のユーザ端子２２よりプリント基板などから離れるように、一対の絡げ端子２２などを曲げる必要がある。また、振動などにより巻線４が大径つば部１３などに当たり難くするために、一対の絡げ端子２２を大きく曲げるのが望ましい。   When the pair of binding terminals 22 integrated with the user terminal 21 are disposed on the same collar portion such as the large-diameter collar portion 13, the antenna device is on the side where the pair of binding terminals 22 are disposed. Mounted on a printed circuit board. At the time of mounting, the pair of binding terminals 22 and both ends of the winding 4 wound around them tend to interfere with other members such as a printed circuit board. Therefore, in general, it is necessary to bend the pair of binding terminals 22 and the like so that the pair of binding terminals 22 is separated from the printed circuit board and the like from the pair of user terminals 22 in the mounted state. Further, in order to make the winding 4 difficult to hit the large-diameter collar portion 13 or the like due to vibration or the like, it is desirable that the pair of binding terminals 22 be largely bent.

これに対して、この実施の形態では、巻線４は、絡げ端子２２の根元に絡げられ、空中配線部は形成されない。断線の可能性を低くするために、一対の絡げ端子２２などを大きく曲げる必要は無い。一対の絡げ端子２２などは、プリント基板などの他の部材と干渉し難い程度に軽く曲げればよい。したがって、一対の絡げ端子２２および一対のユーザ端子２１を、樹脂モールド成形時にインサート成形することにより精度良く位置決めして、且つ、容易に、大径つば部１３などに配設することができる。   On the other hand, in this embodiment, the winding 4 is entangled at the base of the binding terminal 22 and the aerial wiring portion is not formed. In order to reduce the possibility of disconnection, there is no need to greatly bend the pair of binding terminals 22 and the like. The pair of binding terminals 22 and the like may be bent lightly so as not to interfere with other members such as a printed circuit board. Therefore, the pair of binding terminals 22 and the pair of user terminals 21 can be accurately positioned by insert molding at the time of resin molding, and can be easily disposed on the large-diameter collar portion 13 or the like.

以上の実施の形態は、本発明の好適な実施の形態の例であるが、本発明は、これに限定されるものではなく、発明の要旨を逸脱しない範囲において種々の変形や変更が可能である。   The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications and changes can be made without departing from the scope of the invention. is there.

上記実施の形態では、一対の絡げ端子２２は、大径つば部１３の反対側に配設される。この他にもたとえば、一対の絡げ端子２２は、大径つば部１３あるいは小径つば部１２の同一側に配設されていてもよい。   In the above embodiment, the pair of binding terminals 22 are disposed on the opposite side of the large-diameter collar portion 13. In addition, for example, the pair of binding terminals 22 may be disposed on the same side of the large-diameter collar portion 13 or the small-diameter collar portion 12.

図７は、一対の絡げ端子２２が大径つば部１３の同一側に配設されるアンテナ装置１の一例を示す図である。この変形例のアンテナ装置１でも、一対の絡げ端子２２は、大径つば部１３および巻軸部１０の外周面に略垂直な方向に沿った向きで、すなわち巻線用部品２の中心から放射状に延びる方向に沿った向きで配設される。そして、このような一対の絡げ端子２２の配設姿勢にすることで、図７（Ａ）のように、巻軸部１０に対して巻線４が反時計回りに巻かれたとしても、図７（Ｂ）のように、巻軸部１０に対して巻線４が時計回りに巻かれたとしても、巻線４のスタート側の引出部位およびフィニッシュ側の引出部位に、空中配線部が形成されなくなる。テンションをかけて巻線４を一対の絡げ端子２２にからげることで、空中配線部が形成されなくなる。   FIG. 7 is a diagram illustrating an example of the antenna device 1 in which the pair of binding terminals 22 are disposed on the same side of the large-diameter collar portion 13. Also in the antenna device 1 of this modification, the pair of binding terminals 22 are oriented along a direction substantially perpendicular to the outer peripheral surfaces of the large-diameter collar portion 13 and the winding shaft portion 10, that is, from the center of the winding component 2. Arranged in a direction along the radially extending direction. And even if the winding 4 is wound counterclockwise around the winding shaft portion 10 as shown in FIG. As shown in FIG. 7B, even if the winding 4 is wound around the winding shaft portion 10 in the clockwise direction, the aerial wiring portion is formed at the start-side drawing portion and the finish-side drawing portion of the winding 4. No longer formed. By applying tension and winding the winding 4 to the pair of tying terminals 22, the aerial wiring portion is not formed.

上記実施の形態では、一対の絡げ端子２２はともに、大径つば部１３および巻軸部１０の外周面に略垂直な方向に沿った向きで、すなわち巻線用部品２の中心から放射状に延びる方向に沿った向きで配設される。この他にもたとえば、一対の絡げ端子２２の中の一方のもののみが、大径つば部１３および巻軸部１０の外周面に略垂直な方向に沿った向きで、すなわち巻線用部品２の中心から放射状に延びる方向に沿った向きで配設されていてもよい。   In the above embodiment, the pair of binding terminals 22 are both oriented in a direction substantially perpendicular to the outer peripheral surfaces of the large-diameter collar portion 13 and the winding shaft portion 10, that is, radially from the center of the winding component 2. Arranged in a direction along the extending direction. In addition to this, for example, only one of the pair of binding terminals 22 is oriented in a direction substantially perpendicular to the outer peripheral surfaces of the large-diameter collar portion 13 and the winding shaft portion 10, that is, a winding component. You may arrange | position in the direction along the direction extended radially from the center of 2. FIG.

In addition, for example, the large-diameter collar portion 13 and the winding shaft portion 10 of the winding component 2 may be formed in a substantially cylindrical shape such as an elliptical shape or an oval shape, or a substantially disc shape. One of the large-diameter collar portion 13 and the winding shaft portion 10 is one shape selected from a circular shape, an elliptical shape, and an oval shape, and the other is one selected from the remaining portions. It may be a shape.

これらの変形例での巻線用部品２の形状であったとしても、たとえば図８に巻線用部品２の大径つば部１３および巻軸部１０が楕円形状である場合を例示するように、一対の絡げ端子２２は、大径つば部１３および巻軸部１０の外周に略垂直な方向に沿った向きで配設すればよい。これにより、巻線４は、テンションをかけながら一対の絡げ端子２２に絡げられたとき、テンションにより引っ張られ、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。巻線４は、巻線４の巻軸部１０に対する巻方向に関係なく、一対の絡げ端子２２の根元部分（大径つば部１３から突出する根元の部分）に絡げられる。図８は、巻線用部品２の大径つば部１３および巻軸部１０が楕円形状である変形例における、一対の絡げ端子２２の配設向きの説明図である。   Even if it is the shape of the winding component 2 in these modified examples, for example, FIG. 8 illustrates a case where the large-diameter collar portion 13 and the winding shaft portion 10 of the winding component 2 are elliptical. The pair of binding terminals 22 may be disposed in a direction along a direction substantially perpendicular to the outer circumferences of the large-diameter collar portion 13 and the winding shaft portion 10. Thus, when the winding 4 is entangled with the pair of tying terminals 22 while applying tension, the winding 4 is pulled by the tension, and the root portions of the pair of tying terminals 22 (the roots protruding from the large-diameter collar portion 13). Part). Regardless of the winding direction of the winding 4 with respect to the winding shaft portion 10, the winding 4 is entangled with the root portions of the pair of binding terminals 22 (the root portions protruding from the large-diameter collar portion 13). FIG. 8 is an explanatory view of the orientation of the pair of binding terminals 22 in a modification in which the large-diameter collar portion 13 and the winding shaft portion 10 of the winding component 2 are elliptical.
