Description

本発明は、板状体に接着させて用いる端子の技術に関する。   The present invention relates to a technique of a terminal used by being adhered to a plate-like body.

多くの車両の窓ガラスに、ラジオやテレビ用のアンテナがプリントされている。これらのアンテナに給電を行う端子が、アンテナに接触するようにして、窓ガラスの表面に接着される（例えば、特許文献１（図７）参照。）。   Antennas for radio and television are printed on the window glass of many vehicles. A terminal for feeding power to these antennas is adhered to the surface of the window glass so as to contact the antenna (see, for example, Patent Document 1 (FIG. 7)).

特許文献１を次図に基づいて説明する。
図１３（ａ）に示すように、端子１００は、窓ガラスの表面に接着剤１０１を介して接着される略Ｌ字形状の基部１０２と、この基部１０２の両端から一体的に延ばされ窓ガラスに接触する脚部１０３、１０３とからなる。 Patent document 1 is demonstrated based on the following figure.
As shown in FIG. 13 (a), the terminal 100 includes a substantially L-shaped base 102 bonded to the surface of the window glass via an adhesive 101, and a window that is integrally extended from both ends of the base 102. It consists of leg parts 103 and 103 which contact glass.

基部１０２を押し付けるようにして窓ガラスの表面上に配置し、押し付けた状態で接着剤１０１を流し込むことで、端子１００は窓ガラスに接着される。押し付けながら接着させることで、脚部１０３、１０３を窓ガラスに付勢させた状態で接着させることができる。脚部１０３、１０３が窓ガラスに向かって付勢することで、端子１００をアンテナに強く接触させることができる。   By disposing the base portion 102 on the surface of the window glass so as to be pressed and pouring the adhesive 101 in the pressed state, the terminal 100 is bonded to the window glass. By adhering while pressing, the legs 103 and 103 can be adhered in a state of being urged against the window glass. The legs 100 are urged toward the window glass, so that the terminal 100 can be brought into strong contact with the antenna.

ところで、（ｂ）に示すように、端子１００を接着させるには、基部１０２に開けられたスリット１０４、１０４から接着剤を流し込む。スリット１０４、１０４が細いため、接着剤を注入するのが困難であり、時間がかかる。   By the way, as shown in (b), in order to bond the terminal 100, an adhesive is poured from the slits 104, 104 opened in the base 102. Since the slits 104 and 104 are thin, it is difficult to inject the adhesive and it takes time.

この対策の一つとして、スリット１０４、１０４の幅を広げ、接着剤を注入する部位の面積を広げることが考えられる。
しかし、端子の大きさを変えずに接着剤を注入する部位の面積を広げると、接着剤と端子との接着面積が少なくなる。接着面積が少なくなることで、端子の接着力が弱くなる。即ち、図面白抜き矢印で示すように、引っ張り方向へ力が加わった場合に、容易に窓ガラスの表面から剥離するようになる。 As one of countermeasures, it is conceivable to increase the width of the slits 104 and 104 to increase the area of the portion where the adhesive is injected.
However, if the area of the portion where the adhesive is injected is increased without changing the size of the terminal, the bonding area between the adhesive and the terminal is reduced. By reducing the bonding area, the adhesive strength of the terminal is weakened. That is, as indicated by the white arrow in the drawing, when a force is applied in the pulling direction, the sheet easily peels from the surface of the window glass.

所定の強度を保ちつつ、短時間で容易に取付けることができる端子の提供が望まれる。   It is desired to provide a terminal that can be easily attached in a short time while maintaining a predetermined strength.

特開２００９−１０５０３６公報JP 2009-105036 A

本発明は、所定の強度を保ちつつ、短時間で容易に取付けることのできる端子の提供を課題とする。   An object of the present invention is to provide a terminal that can be easily mounted in a short time while maintaining a predetermined strength.

請求項１に係る端子は、板状体の表面に接触する脚部と、この脚部の端部から板状体の表面に対して略平行に延ばされる基部と、この基部と板状体との間の空隙に接着剤を供給する接着剤供給部が設けられている端子において、
接着剤供給部は、基部を板状体に向かって凹ませた凹部と、この凹部に開けられ接着剤を流し込むための穴部とを備えていることを特徴とする。 The terminal according to claim 1 includes a leg portion that contacts the surface of the plate-like body, a base portion that extends substantially parallel to the surface of the plate-like body from an end portion of the leg portion, and the base portion and the plate-like body. In a terminal provided with an adhesive supply section for supplying an adhesive to the gap between
The adhesive supply section is characterized by having a recess having a base recessed toward the plate-like body and a hole for opening the recess and pouring the adhesive.

請求項２に係る端子は、凹部は、球面形状であることを特徴とする。   The terminal according to claim 2 is characterized in that the recess has a spherical shape.

請求項３に係るガラス板は、請求項１又は請求項２記載の端子が接着されていることを特徴とする。   A glass plate according to a third aspect is characterized in that the terminal according to the first or second aspect is bonded.

請求項４に係る移動体用端子付ガラス板は、請求項１又は請求項２記載の端子が接着されていることを特徴とする。   The glass plate with a terminal for a moving body according to a fourth aspect is characterized in that the terminal according to the first or second aspect is bonded.

請求項１に係る発明では、接着剤供給部は、板状体に向かって凹ませた凹部と、この凹部に開けられ接着剤を流し込むための穴部とからなる。凹部に設けられた穴部から接着剤を注入する。細いスリットに向かって注入するのに比べ、接着剤の注入が容易であり、短時間で注入することができる。接着剤の注入が短時間で行うことができることで、端子の取付作業にかかる時間が短くてすむ。   In the invention according to claim 1, the adhesive supply portion includes a concave portion that is recessed toward the plate-like body and a hole portion that is opened in the concave portion and into which the adhesive is poured. Adhesive is injected from the hole provided in the recess. Compared with the injection toward the narrow slit, the injection of the adhesive is easier and can be performed in a short time. Since the injection of the adhesive can be performed in a short time, the time required for attaching the terminal can be shortened.

一方、凹部が設けられることで、接着剤と端子との接触面積を大きくすることができる。大きな穴部を設けた場合であっても、接着剤と端子との接触面積を所定の大きさ以上に保つことができる。接着剤と端子とが所定の大きさ以上の接触面積を有することで、接着強度を所定の強度に保つことができる。
即ち、本発明に係る端子によれば、所定の強度を保ちつつ、短時間で容易に取付けることができる。 On the other hand, the contact area between the adhesive and the terminal can be increased by providing the recess. Even when a large hole is provided, the contact area between the adhesive and the terminal can be maintained at a predetermined size or more. Since the adhesive and the terminal have a contact area of a predetermined size or larger, the adhesive strength can be maintained at a predetermined strength.
That is, the terminal according to the present invention can be easily attached in a short time while maintaining a predetermined strength.

加えて、凹部を設けることで、端子と接着剤との接触面積を広くすることができる。接触面積を広くできるため、大きな穴部を設けた場合であっても、十分な接触面積を得ることができる。穴部を大きくすることで、穴部近傍での接着剤の折れや剥離を防止することができる。   In addition, by providing the recess, the contact area between the terminal and the adhesive can be increased. Since the contact area can be increased, a sufficient contact area can be obtained even when a large hole is provided. By enlarging the hole, it is possible to prevent the adhesive from being broken or peeled off in the vicinity of the hole.

請求項２に係る発明では、凹部は、球面形状である。穴部から注入される接着剤は、球面形状に沿って広がる。球面形状に沿って広がるため、接着剤を凹部の周りに均一に配置させることができる。   In the invention according to claim 2, the concave portion has a spherical shape. The adhesive injected from the hole spreads along the spherical shape. Since it spreads along the spherical shape, the adhesive can be uniformly arranged around the recess.

請求項３に係る発明では、窓ガラスに、請求項１又は請求項２記載の端子が接着されている。端子は、凹部を有し、この凹部に向かって接着剤が注入される。凹部内に接着剤を収めることで、基部から接着剤が突出することを防ぐことができる。基部から接着剤が突出しないことで、外観性が高まる。
加えて、基部から接着剤が突出しないことで、接着剤が給電部に繋がれたハーネスに干渉しなくなる。 In the invention which concerns on Claim 3, the terminal of Claim 1 or Claim 2 is adhere | attached on the window glass. The terminal has a recess, and an adhesive is injected toward the recess. By storing the adhesive in the recess, the adhesive can be prevented from protruding from the base. Appearance improves because the adhesive does not protrude from the base.
In addition, since the adhesive does not protrude from the base portion, the adhesive does not interfere with the harness connected to the power feeding portion.

請求項４に係る発明では、移動体用窓ガラスに、請求項１又は請求項２記載の端子が接着されている。移動体用窓ガラスは、外部からの影響で振動を頻繁に受けるため、特に高い強度で端子を接着させる必要がある。加えて、移動体用窓ガラスには、環境を汚染しない手段で、端子を接着させることが望まれている。本発明に係る移動体用窓ガラスによれば、半田を用いることなく、高い強度で端子を接着させており、望ましい。   In the invention which concerns on Claim 4, the terminal of Claim 1 or Claim 2 is adhere | attached on the window glass for moving bodies. Since the window glass for moving bodies is frequently subjected to vibration due to the influence from the outside, it is necessary to bond the terminals with particularly high strength. In addition, it is desired that terminals be bonded to the window glass for moving bodies by means that do not pollute the environment. The window glass for a moving body according to the present invention is desirable because the terminals are bonded with high strength without using solder.

本発明の実施の形態を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。   Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.

先ず、本発明の実施例１を図面に基づいて説明する。
図１に示すように、端子１０は、表面に給電対象物である導電体１１がプリントされた自動車用の窓ガラス１２に接着される。 First, Embodiment 1 of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the terminal 10 is bonded to a window glass 12 for an automobile on which a conductor 11 as a power supply object is printed.

端子１０は、自動車用の窓ガラスの他、建築用ガラス板等、任意の板状体に用いることができる。
また、導電体としては、アンテナの他、ヒータ等、任意のものを用いることができる。
以下、自動車用窓ガラスに導電体がプリントされている場合を例に説明する。
端子１０の詳細を次図以降で説明する。 The terminal 10 can be used for an arbitrary plate-like body such as an architectural glass plate in addition to an automobile window glass.
In addition to the antenna, any conductor such as a heater can be used as the conductor.
Hereinafter, a case where a conductor is printed on an automobile window glass will be described as an example.
Details of the terminal 10 will be described in the following figures.

図２に示すように、端子１０は、窓ガラス（図１、符号１２）の表面に接触する脚部１４、１４と、これらの脚部１４、１４の端部から窓ガラスの表面に対して略平行に延ばされる基部１５と、この基部１５に溶接され車内の給電部材に繋がれる給電部１６とからなる。   As shown in FIG. 2, the terminal 10 has legs 14 and 14 that contact the surface of the window glass (FIG. 1, reference numeral 12), and ends of these legs 14 and 14 from the surface of the window glass. It consists of a base portion 15 extending substantially in parallel and a power feeding portion 16 welded to the base portion 15 and connected to a power feeding member in the vehicle.

基部１５に溶接された給電部１６の下面に、位置決め部材としての両面テープが接着される位置決め部材接触部１７が設けられる。位置決め部材接触部１７を挟むようにして、球面形状の凹部１８、１８が設けられ、これらの凹部１８、１８のそれぞれの中心に接着剤を注入するための穴である穴部２１、２１が設けられる。
凹部１８と穴部２１とから、接着剤を供給するための接着剤供給部２２はなる。 A positioning member contact portion 17 to which a double-sided tape as a positioning member is bonded is provided on the lower surface of the power feeding portion 16 welded to the base portion 15. Spherical concave portions 18 and 18 are provided so as to sandwich the positioning member contact portion 17, and hole portions 21 and 21 that are holes for injecting adhesive are provided at the centers of the concave portions 18 and 18.
The recess 18 and the hole 21 constitute an adhesive supply unit 22 for supplying an adhesive.

図３に示すように、脚部１４は、平面視でフォーク状に形成され、穴部２１の直径Ｄ１は、基部１５の幅Ｗの０．２５倍とされる。即ち、Ｄ１＝０．２５Ｗである。   As shown in FIG. 3, the leg portion 14 is formed in a fork shape in plan view, and the diameter D <b> 1 of the hole portion 21 is 0.25 times the width W of the base portion 15. That is, D1 = 0.25W.

穴部２１の直径Ｄ１は、基部１５の幅Ｗの０．１倍〜０．８倍であることが望ましい。
穴部２１の直径Ｄ１が、基部１５の幅Ｗの０．１倍よりも小さいと、端子に振動や引張り荷重が加わった場合に、穴部近傍で接着剤の折れや剥離が生じやすくなる。
一方、穴部２１の直径Ｄ１が、基部１５の幅Ｗの０．８倍を超えると、基部１５と接着剤との接触面積を十分に確保することが困難になる。接触面積が小さくなることで、接着強度が弱まる。 The diameter D1 of the hole 21 is preferably 0.1 to 0.8 times the width W of the base 15.
If the diameter D1 of the hole portion 21 is smaller than 0.1 times the width W of the base portion 15, the adhesive is likely to be broken or peeled in the vicinity of the hole portion when a vibration or tensile load is applied to the terminal.
On the other hand, if the diameter D1 of the hole 21 exceeds 0.8 times the width W of the base 15, it is difficult to ensure a sufficient contact area between the base 15 and the adhesive. By reducing the contact area, the adhesive strength is weakened.

穴部２１の直径Ｄ１が、基部１５の幅Ｗの０．１倍〜０．８倍であれば、接着剤を注入する作業が行いやすく、基部１５の強度を十分に保つことができる。   If the diameter D1 of the hole portion 21 is 0.1 to 0.8 times the width W of the base portion 15, the operation of injecting the adhesive can be easily performed, and the strength of the base portion 15 can be sufficiently maintained.

穴部２１を囲う凹部１８の直径Ｄ２は、穴部２１の直径Ｄ１より大きく、且つ基部１５の幅Ｗに対して０．２倍〜０．９倍であることが望ましい。   It is desirable that the diameter D2 of the recess 18 surrounding the hole 21 is larger than the diameter D1 of the hole 21 and is 0.2 to 0.9 times the width W of the base 15.

なお、穴部２１の直径Ｄ１は、０．１５ｍｍ以上である必要がある。穴部２１の直径Ｄ１が基部１５の幅Ｗの０．１倍〜０．８倍の範囲に入る場合であっても、穴部２１の直径Ｄ１が１．５ｍｍ未満であると接着剤が注入し難くなるからである。
即ち、穴部２１の直径Ｄ１は、１．５ｍｍ以上であり、且つ基部１５の幅Ｗの０．１倍〜０．８倍であることが望ましい。
端子の窓ガラスへの接着方法を次図で説明する。 In addition, the diameter D1 of the hole part 21 needs to be 0.15 mm or more. Even when the diameter D1 of the hole 21 falls within the range of 0.1 to 0.8 times the width W of the base 15, the adhesive is injected when the diameter D1 of the hole 21 is less than 1.5 mm. Because it becomes difficult.
That is, the diameter D1 of the hole 21 is preferably 1.5 mm or more and 0.1 to 0.8 times the width W of the base 15.
The method for bonding the terminal to the window glass will be described with reference to the following figure.

図４（ａ）に示すように、まず、位置決め部材接触部１７に両面テープ２４を接着させる。
次に、（ｂ）に示すように、導電体１１がプリントされた窓ガラス１２の上面に端子１０を移動させ、給電部１６を押さえつけるようにして両面テープ２４を窓ガラス１２の上面に接着させる。 As shown in FIG. 4A, first, the double-sided tape 24 is bonded to the positioning member contact portion 17.
Next, as shown in (b), the terminal 10 is moved to the upper surface of the window glass 12 on which the conductor 11 is printed, and the double-sided tape 24 is adhered to the upper surface of the window glass 12 so as to press down the power feeding portion 16. .

（ｃ）に示すように、窓ガラス１２の上面に接着させた端子１０の穴部２１に接着剤２５を注入する。両面テープ２４と共に接着剤２５を用いて端子１０を窓ガラス１２の上面に接着させることで、端子１０の窓ガラス１２への取付作業が終了する。
窓ガラス１２へ接着された端子１０について詳細を次図で説明する。 As shown in (c), an adhesive 25 is injected into the hole 21 of the terminal 10 adhered to the upper surface of the window glass 12. By attaching the terminal 10 to the upper surface of the window glass 12 using the adhesive 25 together with the double-sided tape 24, the operation of attaching the terminal 10 to the window glass 12 is completed.
The details of the terminal 10 bonded to the window glass 12 will be described with reference to the next drawing.

図５に示すように、端子１０は、両面テープ２４及び接着剤２５、２５を介して窓ガラス１２の上面に接着される。両面テープ２４を接着させる際に、端子１０を押し付けながら接着させたことで、脚部１４、１４は導電体１１に向かって付勢した状態で接着される。付勢した状態で接着されることで、高い強度で脚部１４、１４が導電体１１に接触する。   As shown in FIG. 5, the terminal 10 is bonded to the upper surface of the window glass 12 through a double-sided tape 24 and adhesives 25 and 25. When the double-sided tape 24 is bonded, the legs 10 are bonded in a state of being biased toward the conductor 11 by pressing and bonding the terminals 10. By being bonded in a biased state, the legs 14 and 14 are in contact with the conductor 11 with high strength.

凹部１８に設けられた穴部２１から接着剤２５を注入するため、細いスリットに向かって注入するのに比べ、接着剤２５の注入が容易であり、短時間で注入することができる。接着剤２５の注入が短時間で行うことができることで、端子１０の取付作業にかかる時間が短くてすむ。
このようにして取り付けられる端子１０の作用について次図で詳細に説明する。 Since the adhesive 25 is injected from the hole 21 provided in the recess 18, the adhesive 25 can be injected more easily than in the case of injecting toward the narrow slit, and can be injected in a short time. Since the injection of the adhesive 25 can be performed in a short time, the time required for attaching the terminal 10 can be shortened.
The effect | action of the terminal 10 attached in this way is demonstrated in detail with the following figure.

図６（ａ）の比較例に示すように、端子１１０に対して、引張り方向（白抜き矢印参照）に向かって力が加わることがある。基部１１１の上面に接着剤１１３ａが配置されることで、特に穴部１１２及び穴部１１２近傍の基部１１１ａでは、接着剤１１３ａが端子１１０の抜けを防ぐように作用する（矢印参照）。   As shown in the comparative example of FIG. 6A, a force may be applied to the terminal 110 in the pulling direction (see the white arrow). By disposing the adhesive 113a on the upper surface of the base 111, the adhesive 113a acts to prevent the terminal 110 from coming off, particularly at the hole 112 and the base 111a in the vicinity of the hole 112 (see arrows).

穴部１１２の直径が大きいほど、端子１１０の抜けを防止しやすくなる。即ち、端子１１０の接着強度を上げることができる。しかし、穴部１１２の直径を大きくしすぎると、基部１１１と接着剤１１３との接触面積が減少し、却って接着強度が弱まる。   As the diameter of the hole 112 is larger, it is easier to prevent the terminal 110 from coming off. That is, the adhesive strength of the terminal 110 can be increased. However, if the diameter of the hole 112 is too large, the contact area between the base 111 and the adhesive 113 is reduced, and the adhesive strength is weakened.

一方、穴部１１２の直径を小さくすると、接触面積を増加させることができる。しかし、穴部１１２が小さいと、引張り方向に力が加わった場合に、穴部１１２近傍で接着剤１１３の折れや剥離が生じやすくなる。   On the other hand, when the diameter of the hole 112 is reduced, the contact area can be increased. However, if the hole 112 is small, the adhesive 113 is likely to be broken or peeled in the vicinity of the hole 112 when a force is applied in the pulling direction.

（ｂ）に示すように、実施例に係る端子１０によれば、凹部１８を設けて、この凹部１８に開けられた穴部２１から接着剤２５を注入する。凹部１８が設けられることで、接着剤２５と端子１０との接触面積を大きくすることができる。大きな穴部２１を設けた場合であっても、接着剤２５と端子１０との接触面積を所定の大きさ以上に保つことができる。接着剤２５と端子１０とが所定の大きさ以上の接触面積を有することで、接着強度を所定の強度に保つことができる。
即ち、本発明に係る端子１０によれば、所定の強度を保ちつつ、短時間で容易に取付けることができる。 As shown in (b), according to the terminal 10 according to the embodiment, the recess 18 is provided, and the adhesive 25 is injected from the hole 21 formed in the recess 18. By providing the recess 18, the contact area between the adhesive 25 and the terminal 10 can be increased. Even when the large hole 21 is provided, the contact area between the adhesive 25 and the terminal 10 can be maintained at a predetermined size or more. Since the adhesive 25 and the terminal 10 have a contact area of a predetermined size or more, the adhesive strength can be maintained at a predetermined strength.
That is, the terminal 10 according to the present invention can be easily attached in a short time while maintaining a predetermined strength.

加えて、本発明による端子１０によれば、大きな穴部２１を設けることができる。大きな穴部２１を設けることができることで、より確実に端子１０の抜け、即ち接着剤２５からの剥離を防ぐことができる。   In addition, according to the terminal 10 according to the present invention, the large hole 21 can be provided. Since the large hole portion 21 can be provided, it is possible to more reliably prevent the terminal 10 from coming off, that is, peeling from the adhesive 25.

さらに、凹部１８内に接着剤２５ａを収めることで、基部１５から接着剤２５ａが突出することを防ぐことができる。基部１５から接着剤２５ａが突出しないことで、外観性が高まる。   Furthermore, it is possible to prevent the adhesive 25 a from protruding from the base portion 15 by storing the adhesive 25 a in the recess 18. Since the adhesive 25a does not protrude from the base portion 15, the appearance is enhanced.

加えて、凹部１８を設けることで、端子１０と接着剤２５との接触面積を広くすることができる。接触面積を広くできるため、大きな穴部２１を設けた場合であっても、十分な接触面積を得ることができる。穴部２１を大きくすることで、穴部２１近傍での接着剤２５の折れや剥離を防止することができる。   In addition, by providing the recess 18, the contact area between the terminal 10 and the adhesive 25 can be increased. Since the contact area can be increased, a sufficient contact area can be obtained even when the large hole 21 is provided. By enlarging the hole 21, it is possible to prevent the adhesive 25 from being broken or peeled in the vicinity of the hole 21.

さらに、凹部１８を設けることで端子１０の接着に必要な接着剤２５の量が減る。接着剤２５の量が減ることで、端子付窓ガラス（図１、符号１２）の製造コストの低減を図ることができる。また、接着剤２５の量が減ることで、接着剤２５を注入するのに必要な時間や接着剤２５が硬化するのに必要な時間を短縮でき、端子付き窓ガラス（端子付ガラス板又は移動体用端子付ガラス板）の製造時間を短縮することができる。   Furthermore, the amount of the adhesive 25 necessary for bonding the terminal 10 is reduced by providing the recess 18. By reducing the amount of the adhesive 25, it is possible to reduce the manufacturing cost of the terminal-attached window glass (FIG. 1, reference numeral 12). Further, by reducing the amount of the adhesive 25, the time required for injecting the adhesive 25 and the time required for the adhesive 25 to cure can be shortened. Manufacturing time of the glass plate with terminal for body) can be shortened.

加えて、凹部１８は、球面形状である。穴部２１から注入される接着剤２５は、球面形状に沿って広がる。球面形状に沿って広がるため、接着剤２５を凹部１８の周りに均一に配置させることができる。
本発明に係る端子の別実施例について次図以降で説明する。 In addition, the recess 18 has a spherical shape. The adhesive 25 injected from the hole 21 spreads along the spherical shape. Since it spreads along the spherical shape, the adhesive 25 can be uniformly arranged around the recess 18.
Another embodiment of the terminal according to the present invention will be described in the following figures.

次に、本発明の実施例２を図面に基づいて説明する。
図７に示すように、実施例２に係る端子３０では、接着剤供給部３１は、基部３２に接着剤を供給するために開けられた方形の穴部３３と、この穴部３３を中心に略Ｘ字状に切欠き３４が設けられ、これらの切欠き３４に挟まれた部位を窓ガラス側（図面裏面）に押し込むことで形成された凹部３５とからなる。
穴部３３が方形である場合は、各辺が１．５ｍｍ以上であると、接着剤の注入が容易である。 Next, a second embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 7, in the terminal 30 according to the second embodiment, the adhesive supply unit 31 includes a rectangular hole 33 opened to supply the adhesive to the base 32, and the hole 33 as a center. A notch 34 is provided in a substantially X shape, and includes a recess 35 formed by pushing a portion sandwiched between these notches 34 into the window glass side (the back side of the drawing).
In the case where the hole 33 is square, the adhesive can be easily injected when each side is 1.5 mm or more.

このような形状に接着剤供給部３１を形成した場合も、細いスリットに向かって注入するのに比べ、接着剤の注入が容易であり、短時間で注入することができる。接着剤の注入が短時間で行うことができることで、端子の取付作業にかかる時間が短くてすむ。   Even when the adhesive supply part 31 is formed in such a shape, it is easier to inject the adhesive and inject in a shorter time than injecting toward the narrow slit. Since the injection of the adhesive can be performed in a short time, the time required for attaching the terminal can be shortened.

なお、予め穴部３３を設けておく他に、後から穴部を設けることもできる。
即ち、まず、切欠きを略Ｘ字状に設け、これらの切欠きに挟まれた略三角形の部位を窓ガラス側に押し込むことで斜面を形成する。これらの斜面で囲われた部位が凹部である。また、略三角形の部位を押し込むことで、三角形の頂点で囲われた隙間が生じる。この隙間を接着剤を注入するための穴部とすることができる。このような方法で製造した場合も、同様の効果を得ることができる。
実施例３に係る端子を次図で説明する。 In addition to providing the hole 33 in advance, a hole can be provided later.
That is, first, a notch is provided in a substantially X shape, and an inclined surface is formed by pushing a substantially triangular portion sandwiched between these notches into the window glass side. A portion surrounded by these slopes is a recess. Moreover, the space enclosed by the triangle vertex arises by pushing in the substantially triangular site | part. This gap can be used as a hole for injecting the adhesive. Similar effects can also be obtained when manufactured by such a method.
A terminal according to Example 3 will be described with reference to the following diagram.

図８（ａ）に示すように、実施例３に係る端子４０では、接着剤供給部４１は、窓ガラスに向かって（図面裏面側）球面状に凹まされる凹部１８と、この凹部１８の底部に設けられ接着剤を供給する穴部２１と、この穴部２１を囲うようにして開けられた複数（この例では４つ）の補強穴部４２とからなる。   As shown in FIG. 8A, in the terminal 40 according to the third embodiment, the adhesive supply unit 41 includes a concave portion 18 that is recessed in a spherical shape toward the window glass (the back side of the drawing), and a bottom portion of the concave portion 18. And a plurality of (four in this example) reinforcing hole portions 42 formed so as to surround the hole portion 21.

（ｂ）に示すように、穴部２１から接着剤２５を注入する。球面形状に沿って広がった接着剤２５は、（ｃ）に示すように、補強穴部４２を通過して凹部１８の上面に流入する。   As shown in (b), the adhesive 25 is injected from the hole 21. The adhesive 25 spreading along the spherical shape passes through the reinforcing hole 42 and flows into the upper surface of the recess 18 as shown in FIG.

所定の高さまで達した接着剤２５が、補強穴部４２から凹部１８の上面に流入するため、凹部１８と窓ガラス１２との間に均一に接着剤２５を塗布することができる。
また、補強穴部４２から接着剤２５が凹部１８に流入するため、所定の量の接着剤２５が注入されたことを容易に確認することができる。 Since the adhesive 25 having reached a predetermined height flows into the upper surface of the recess 18 from the reinforcing hole 42, the adhesive 25 can be uniformly applied between the recess 18 and the window glass 12.
Further, since the adhesive 25 flows into the concave portion 18 from the reinforcing hole portion 42, it can be easily confirmed that a predetermined amount of the adhesive 25 has been injected.

さらに、補強穴部４２が設けられることで、より確実に端子４０の抜けを防ぐことができる。
実施例４に係る端子を次図で説明する。 Furthermore, the provision of the reinforcing hole portion 42 can more reliably prevent the terminal 40 from coming off.
A terminal according to Example 4 will be described with reference to the following diagram.

図９に示すように、実施例４に係る端子５０では、凹部５１は、球面状に凹せ、且つ絞り加工が施された。即ち、凹部５１は、全体として球面状とされつつ、表面が波形状に形成されている。   As shown in FIG. 9, in the terminal 50 according to Example 4, the recess 51 was recessed into a spherical shape and subjected to drawing. That is, the concave portion 51 is formed into a spherical shape as a whole, and the surface thereof is formed into a wave shape.

表面が波形状とされることで、接着剤２５との接触面積をさらに大きく取ることができ、端子５０の接着強度をより高めることができる。   By making the surface corrugated, the contact area with the adhesive 25 can be further increased, and the adhesive strength of the terminal 50 can be further increased.

なお、凹部５１には、断面視波形状の他、ポンチを押付けることで形成される窪み（ディンプル）形状、薬品を塗布することで形成される粗面等、凹部５１と接着剤２５との接触面積を増加させるためのあらゆる手段を講じることができる。   In addition to the cross-sectional wave shape, the concave portion 51 includes a concave portion (dimple) formed by pressing a punch, a rough surface formed by applying a chemical, and the like. Any means for increasing the contact area can be taken.

図１０（ａ）に示すように、参考例に係る端子６０は、ガラス（（ｂ）、符号７０）の表面に接触する脚部６１、６１と、これらの脚部６１、６１の端部から窓ガラスの表面に対して略平行に延ばされる基部６２と、この基部６２に溶接され車内の給電部材に繋がれる給電部６３とからなる。   As shown to Fig.10 (a), the terminal 60 which concerns on a reference example from the edge part of these leg parts 61 and 61, and the leg parts 61 and 61 which contact the surface of glass ((b), code | symbol 70). It comprises a base portion 62 that extends substantially parallel to the surface of the window glass, and a power feeding portion 63 that is welded to the base portion 62 and connected to a power feeding member in the vehicle.

基部６２に溶接された給電部６３の下面に、両面テープが接着される位置決め部材接触部６４が設けられる。基部６２に開けられた窓状開口部６５と、この窓状開口部６５の近傍から基部６２の幅方向に向かって延ばされる延長部６６、６６とを有する。   A positioning member contact portion 64 to which a double-sided tape is bonded is provided on the lower surface of the power feeding portion 63 welded to the base portion 62. It has a window-like opening 65 opened in the base 62, and extensions 66, 66 extending in the width direction of the base 62 from the vicinity of the window-like opening 65.

延長部６６、６６の先端６６ａ、６６ａは、それぞれ半円形状に形成されている。
端子６０は、延長部６６、６６を基部６２の裏面側（図面裏面側）に向かって折曲げることで形成される。 The ends 66a and 66a of the extensions 66 and 66 are each formed in a semicircular shape.
The terminal 60 is formed by bending the extension portions 66 and 66 toward the back surface side (the back surface side in the drawing) of the base portion 62.

（ｂ）に示すように、先端６６ａ、６６ａが接触するように延長部６６、６６を折り曲げ、折曲げ形状部６８を形成する。
先端６６ａ、６６ａが接触することで、接着剤を注入するための小孔６９が形成される。即ち、折曲げ形状部６８に小孔６９が形成される。窓状開口部６５から接着剤をガラス７０に向かって注入することで、端子６０がガラス７０に接着される。ガラス７０の表面には、被給電部７１がプリントされている。端子６０の接着剤供給部７２は、折曲げ形状部６８と、小孔６９とからなる。 As shown in (b), the extension portions 66 and 66 are bent so that the tips 66a and 66a are in contact with each other, thereby forming a bent shape portion 68.
When the tips 66a and 66a come into contact with each other, a small hole 69 for injecting the adhesive is formed. That is, a small hole 69 is formed in the bent shape portion 68. The terminal 60 is bonded to the glass 70 by injecting an adhesive toward the glass 70 from the window-shaped opening 65. A power-supplied part 71 is printed on the surface of the glass 70. The adhesive supply portion 72 of the terminal 60 includes a bent shape portion 68 and a small hole 69.

（ｂ）のｃ−ｃ線断面図である（ｃ）に示すように、窓状開口部６５から小孔６９を介して接着剤７３を注入する。細いスリットに向かって注入するのに比べ、接着剤７３の注入が容易であり、短時間で注入することができる。接着剤７３の注入が短時間で行うことができることで、端子６０の取付作業にかかる時間が短くてすむ。   As shown in (c), which is a sectional view taken along the line cc of (b), the adhesive 73 is injected from the window-like opening 65 through the small hole 69. Compared with the injection toward the narrow slit, the adhesive 73 can be injected more easily and can be injected in a short time. Since the injection of the adhesive 73 can be performed in a short time, the time required for attaching the terminal 60 can be shortened.

さらに、折曲げ形状部６８内に接着剤７３を収めることで、基部６２から接着剤７３が突出することを防ぐことができる。基部６２から接着剤７３が突出しないことで、外観性が高まる。   Furthermore, it is possible to prevent the adhesive 73 from protruding from the base portion 62 by accommodating the adhesive 73 in the bent shape portion 68. Since the adhesive 73 does not protrude from the base 62, the appearance is enhanced.

さらに、折曲げ形状部６８を設けることで端子６０の接着に必要な接着剤７３の量が減る。接着剤７３の量が減ることで、端子付ガラス板の製造コストの低減を図ることができる。また、接着剤７３の量が減ることで、接着剤７３を注入するのに必要な時間や接着剤７３が硬化するのに必要な時間を短縮でき、端子付窓ガラスの製造時間を短縮することができる。
なお、接着剤７３を注入する前の工程については、図４を参照。 Furthermore, the amount of the adhesive 73 required for bonding the terminal 60 is reduced by providing the bent shape portion 68. By reducing the amount of the adhesive 73, the manufacturing cost of the terminal-attached glass plate can be reduced. Further, by reducing the amount of the adhesive 73, the time required for injecting the adhesive 73 and the time required for the adhesive 73 to cure can be shortened, and the manufacturing time of the terminal-attached window glass can be shortened. Can do.
Refer to FIG. 4 for the process before the adhesive 73 is injected.

The projections 83 and 83 can be formed by projecting toward the bottom. For example, four protrusions 83 and 83 are provided on the bottom 82.

位置決め部材としてスペーサ８１、８１を用いる場合は、以下のような手順で端子１０を窓ガラス１２へ接着させる。即ち、窓ガラス１２側へ向かって、基部１５を押し付ける。押付けることで、窓ガラス１２とスペーサ８１及びスペーサ８１と位置決め部材接触部１７とが接触する。これらが接触した状態で、接着剤２５を注入する。接着剤２５を注入し硬化させることで、窓ガラス１２へ端子１０を接着させることができる。   When the spacers 81 are used as the positioning members, the terminals 10 are bonded to the window glass 12 in the following procedure. That is, the base 15 is pressed toward the window glass 12 side. By pressing, the window glass 12 and the spacer 81 and the spacer 81 and the positioning member contact portion 17 come into contact with each other. The adhesive 25 is injected in a state where they are in contact with each other. The terminal 10 can be bonded to the window glass 12 by injecting and curing the adhesive 25.

給電部１６の底部８２に突起部８３、８３を形成する場合も同様の方法により、ガラス板１２に端子１０を接着させることができる。
スペーサ８１と位置決め部材接触部１７とは、予め両面テープ等によって接着させておいてもよい。 Even when the protrusions 83 and 83 are formed on the bottom portion 82 of the power supply unit 16, the terminal 10 can be bonded to the glass plate 12 by the same method.
The spacer 81 and the positioning member contact portion 17 may be bonded in advance with a double-sided tape or the like.

スペーサ８１や突起部８３を用いた場合には、高さ方向への位置決めを行うことができる。
水平方向及び高さ方向の両方へ正確に位置決めを行う場合には、スペーサ８１の底面に両面テープを接着させ、両面テープを介してスペーサ８１を窓ガラス１２に接着させることもできる。 When the spacer 81 or the protrusion 83 is used, positioning in the height direction can be performed.
When positioning is performed accurately both in the horizontal direction and in the height direction, a double-sided tape can be adhered to the bottom surface of the spacer 81, and the spacer 81 can be adhered to the window glass 12 via the double-sided tape.
