Description
技术领域
本发明涉及带金属端子车辆用窗玻璃。
背景技术
车辆用窗玻璃上,例如为了防雾或融冰,有时会在玻璃板的表面上设置由导电体构成的电热部件。另外,车辆用窗玻璃上,有时还会在玻璃板的表面上设置由导电体构成的天线供收音机、电视、无线通信或传感器用。
为了向导电体供电或收发信号等,金属端子藉由焊料与车辆用窗玻璃的导电体电连接。而且,金属端子固定于与车辆内配置的电源或信号源电连接的导线上。以往,导电体藉由有铅焊料与金属端子连接。有铅焊料的粘接功能优异、具有高塑性变形能力,因此焊接时的残余应力易缓和。所以,玻璃板表面上的导电体和金属端子能够藉由有铅焊料容易地粘接。但是,近年来,铅对人体和环境的影响受到诟病,因此车辆用窗玻璃用途推荐采用无铅焊料。
例如,专利文献1中公开了一种带金属端子车辆用窗玻璃,其具备玻璃基板、玻璃基板上的导电层、以及导电层上的藉由无铅焊料连接的金属端子。专利文献2中公开了一种带金属端子车辆用窗玻璃,其中,藉由无铅焊料连接玻璃板表面上的端子连接部(导电体)与金属端子时,无铅焊料不使用弹性模量低的铅,因此其比有铅焊料的弹性模量大,伴随温度变化而产生的应力容易变大,因而随着焊接时等的玻璃板温度变化而在玻璃板上产生残余应力,其结果是,玻璃板的表面容易产生裂纹。于是,专利文献2中公开,对于玻璃板的残余应力所引起的玻璃板裂纹,通过在对配置于玻璃板上的导电体焊接金属端子时对玻璃板进行预热,能够抑制玻璃板的残余应力。

发明内容
发明所要解决的技术问题
通常,带金属端子车辆用窗玻璃在玻璃板的主面上配置遮蔽层,在遮蔽层上配置导电体,导电体藉由无铅焊料与金属端子连接。然而,与焊接金属端子时的玻璃板温度变化而产生的玻璃板残余应力所引起的裂纹(初始裂纹)不同的是,在焊接金属端子后经过数日以上,会以配置于玻璃板主面上的遮蔽层或配置于遮蔽层上的导电体的物理上薄弱部位为起点而在遮蔽层或导电体上产生裂纹。而且,由于在遮蔽层或导电体上产生的裂纹,有时遮蔽层下的玻璃表面会部分剥离。
本发明鉴于上述技术问题而完成,其目的是提供即使在藉由无铅焊锡将配置于玻璃板主面上的遮蔽层上的导电体与金属端子连接后经过数日以上也能抑制遮蔽层或导电体产生裂纹并能抑制遮蔽层下的玻璃板表面剥离的带金属端子车辆用窗玻璃。
解决技术问题的手段
根据本发明一个方面,带金属端子车辆用窗玻璃具备:玻璃板、配置于玻璃板的至少一个主面上的遮蔽层、配置于遮蔽层上的导电体、藉由无铅焊锡与导电体电连接的金属端子、以及固定于金属端子上的导线,金属端子具备藉由无铅焊锡与端子连接部连接的台座部,导电体具备藉由无铅焊锡与台座部连接的端子连接部、以及与端子部连结且宽度比端子连接部的长度方向或横向方向的宽度窄的连结部,俯视下,端子连接部与连结部以端子连接部整周的30%以下连结,端子连接部的缘部相对于构成台座部的台座缘部位于从台座部离开的方向上不超过3mm的位置处。
发明效果
根据本发明一个方面的带金属端子车辆用窗玻璃,即使在藉由无铅焊锡将配置于玻璃板主面上的遮蔽层上的导电体与金属端子连接后经过数日以上也能抑制配置于玻璃板主面上的遮蔽层或配置于遮蔽层上的导电体产生裂纹并能抑制遮蔽层下的玻璃板表面剥离。

具体实施方式
下面参照附图对本发明的带金属端子车辆用窗玻璃的几个实施方式进行说明。但是,以下实施方式中记载的构成要素仅为例示,本发明的技术范围并不仅限于这些构成要素。
(金属端子)
参照附图对安装在带金属端子车辆用窗玻璃上的金属端子进行说明。图1是金属端子的一个实施方式的立体图。
如图1所示,金属端子10具备:脚连结部11、与脚连结部11连接的第一脚部12、与第一脚部12连接的第一台座部14、与脚连结部11连接的第二脚部13、与第二脚部13连接的第二台座部15。第一脚部12和第二脚部13具有使脚连结部11与导电体隔开的功能。金属端子10具备与脚连结部11连接的导线连接部16。脚连结部11连接第一脚部12和第二脚部13和导线连接部16。
脚连结部11的上表面为大致矩形,具有两条长边和两条短边。两条长边大致平行,两条短边也大致平行。第一脚部12和第二脚部13分别与脚连结部11的短边连接。第一脚部12和第二脚部13的宽度等于脚连结部11的短边长度。
第一台座部14向第一脚部12的宽度方向突出。同样,第二台座部15向第二脚部13的宽度方向突出。第一台座部14和第二台座部15比脚连结部11的短边长。
第一台座部14和第二台座部15是藉由焊料与形成于玻璃板上的导电体电连接的部分。第一台座部14上形成有两个凹陷14A。通过形成凹陷14A,凹陷14A的形成面的反向面突出。同样,第二台座部15上形成有两个凹陷15A。通过形成凹陷15A,凹陷15A的形成面的反向面突出。凹陷14A和15A的个数不限于2个。
导线连接部16具备与脚连结部11连接的延伸部16A和与延伸部16A连接的固定部16B。延伸部16A与脚连结部11的长边连接,与脚连结部11共面。延伸部16A沿着与第一台座部14和第二台座部15的突出部相同的方向延伸。
固定部16B具有固定导线的功能。本实施方式中,固定部16B构成为紧固部。紧固部具有相向的一对壁部和将一对壁部的端部连结的壁连结部,在从与延伸部16A的方向相反的方向观察正面时,具有U字形状。U字形状的紧固部朝向第一台座部14和第二台座部15侧开口。但是,U字形状的紧固部也可以朝向与第一台座部14和第二台座部15突出的方向相反的一侧开口。作为紧固部以外的结构,固定部16B也可以是钎焊部或焊接部。
金属端子10可以包含铜、黄铜、铁、铬以及含铜合金、含黄铜合金、含铁合金和含铬合金中的至少一种。可以根据需要对金属端子10的表面实施表面加工(镀锡等)。另外,金属端子10的板厚优选为0.4mm以上0.8mm以下。金属端子10通过对金属板进行冲压(press)、弯曲(bending)而得。
另外,固定部16B和固定于固定部16B中的一部分导线可以被由绝缘体构成的保护部件所覆盖。绝缘体由绝缘材料形成,例如由树脂形成。树脂优选为挠性优异的材料。树脂的种类无特别限定,例如可以使用聚氯乙烯、氟树脂、天然橡胶、合成橡胶、聚对苯二甲酸乙二醇酯、聚烯烃或聚酰亚胺等。固定部16B和固定于固定部16B中的一部分导线被由绝缘体构成的保护部件覆盖时,即使对金属端子10或导线施加外力使金属端子10变形而与车辆用窗玻璃或金属制的车身直接接触,也不会损伤车辆用窗玻璃,而且不会与车身短路,因此优选。
(带金属端子车辆用窗玻璃)

本申请的发明人们对于经过数日以上之后以遮蔽层或导电体的物理上薄弱部位为起点而在遮蔽层或导电体上产生裂纹导致遮蔽层下的玻璃表面部分剥离的情况进行了研究,该情况不同于将金属端子藉由无铅焊料与形成于玻璃板上的遮蔽层上所形成的导电体连接后因焊接金属端子时的玻璃板温度变化而产生的玻璃板残余应力所引起的裂纹(初始裂纹)。结果,本发明人们发现,无铅焊料的扩展、以及导电体40和台座部的大小,与形成于遮蔽层上的导电体藉由无铅焊料连接后经过数日以上之后以遮蔽层或导电体的物理上薄弱部位为起点而在遮蔽层或导电体上产生裂纹有关,从而创造了本发明。
(第一实施方式)
下面对本发明的第一实施方式的带金属端子车辆用窗玻璃进行说明。图3是配置于玻璃板30上的导电体40的俯视图。导电体40对于金属端子的第一和第二台座部分别具备汇流条部41、端子连接部42、以及连接汇流条部41和端子连接部42的3个连结部43。汇流条部41和端子连接部42和连结部43电连接。
导电体40的汇流条部41具有比连结部43的至少一部分宽的宽度。通过扩大汇流条部41的宽度,能够降低电阻,抑制通电时的温度上升。
图3中,端子连接部42是藉由无铅焊料与金属端子的第一台座部14和第二台座部15(未图示)电连接的部分。端子连接部42和汇流条部41经由连结部43进行来自金属端子10(未图示)的供电或信号等的收发。
图4是示出金属端子10(用虚线表示)与导电体40连接的状态的俯视图。如图4所示,第一台座部14和第二台座部15在端子连接部42的区域中藉由焊料50(未图示)连接。
图5是图4的放大图。图5中,用虚线表示金属端子10的外形。导电体40具有端子连接部42、与端子连接部42的对置的长边中的一条长边连结的2个连结部43、以及与另一条长边连结的连结部43。导电体40具备共计3个连结部43。3个连结部43的宽度相等。
端子连接部42在俯视下由其缘部确定形状。第一实施方式中,各端子连接部42的形状由四个直线部分的缘部确定为大致矩形。边缘不仅可以是直线,也可以是曲线、或直线与曲线的组合。
另外,在端子连接部42的缘部处,不具有与连结部43连结的部位的部分成为所见的缘部确定端子连接部42形状的要素。在端子连接部42与连结部43连结的部位处,沿着缘部延长的假想线(双点划线)构成缘部,成为确定端子连接部42形状的要素。由包含假想线的连续的缘部确定端子连接部42的整周。
如图5所示,连结部43具有比端子连接部42的长度方向或横向方向的宽度窄的宽度。长度方向是俯视下的第一方向,横向方向是与长度方向正交的第二方向。宽度是相向的边缘之间的距离。连结部43只要具有比端子连接部42的长度方向或横向方向的宽度窄的宽度之一即可。
第一台座部14在俯视下由其台座缘部确定形状。第一实施方式中,第一台座部14的形状由四个直线构成的缘部和两个圆弧构成的缘部确定。台座缘部可以是直线、曲线、或直线与曲线的组合。
第一台座部14的缘部相对于端子连接部42的缘部位于外侧。因此,端子连接部42的大小比第一台座部14的大小要小。
图6是沿图5中的VI-VI线的剖视图。图6示出带金属端子车辆用窗玻璃100中的玻璃板30、配置于玻璃板30上的遮蔽层70、以及配置于遮蔽层70上的端子连接部42、藉由焊料50与端子连接部42电连接的金属端子10的第一台座部14。
第一台座部14的缘部相对于端子连接部42的缘部位于外侧,因此焊料50的下底比上底短,在剖视下为大致梯形的形状。可以像图6中用圆形标记包围所示那样使端子连接部42的缘部与焊料50的缘部一致,其结果是,能够在将金属端子10用无铅焊料连接到配置于遮蔽层70上的导电体40后经过数日以上之后也能抑制遮蔽层70或导电体40上产生裂纹。即,通过使端子连接部42的缘部与焊料50的缘部一致,能够抑制遮蔽层70或导电体40上容易生成的裂纹起点产生,能够抑制遮蔽层70下的玻璃板30表面部分剥离。
另外,如图5所示,在端子连接部42与连结部43连结的部分处,认为焊料50沿着连结部43超出端子连接部42的缘部,从而会发生不易使端子连接部42的缘部与焊料50的缘部一致的情况。于是,在第一实施方式中,俯视下,端子连接部42与连结部43以端子连接部42整周的30%以下连接。通过使端子连接部42与连结部43以端子连接部42整周的30%以下连接,能够增大使端子连接部42的缘部与焊料50的缘部一致的区域。而且,通过使端子连接部42与连结部43以端子连接部42整周的30%以下连接,也能确保金属端子10与导电体40的接合强度。
在将端子连接部42的整周(包含所见的缘部和双点划线)设为L1、端子连接部42与连结部43连结的部分的长度(仅双点划线的长度)设为L2的情况下,通过计算(L2/L1)×100,可以判断是否在端子连接部42整周的30%以下。
图7A至图7F和图8G至图8I是示出第一实施方式的变形例的俯视图。在图7A至图7F和图8G至图8I所示的各变形例中,第一台座部14的缘部都相对于端子连接部42的缘部位于外侧。

在图7B所示的变形例中,导电体40具备汇流条部41、端子连接部42、以及分别与端子连接部42的对置的长边连结的连结部43。导电体40具备共计2个连结部43。2个连结部43的宽度不同。

如图8H所示,导电体40具备汇流条部41、端子连接部42、分别与端子连接部42的对置的短边连结的2个连结部43、以及分别与端子连接部42的对置的长边连结的连结部43。导电体40具备共计6个连结部43。6个连结部43的宽度相等。
在图8I所示的变形例中,导电体40具备汇流条部41、端子连接部42、与端子连接部42的对置的长边中的一条长边连结的2个连结部43、以及与另一条长边连结的4个连结部43。导电体40具备共计6个连结部43。6个连结部43的宽度相等。
图7A至图7F和图8G至图8I所示的各变形例的端子连接部42的面积相等。另外,图7A至图7F和图8G~图8I所示的各变形例的连结部43的总面积相等。
关于图4至图8I所示的变形例,对第一台座部14进行了说明,但关于各变形例对第一台座部14说明的事项也可适用于第二台座部15。此外,在对各变形例的说明中,对第一台座部14说明的事项也可以适用于与具有2个台座部(第一台座部14和第二台座部15)的金属端子10不同的、具有1个台座部或3个以上的台座部的金属端子。
端子连接部42与连结部43的连结结构并不限定于图7A至图7F和图8G至图8I的示例,可以适当变更,只要第一台座部14的缘部相对于端子连接部42的缘部位于外侧即可。
(第二实施方式)
接着,对本发明的第二实施方式的带金属端子车辆用窗玻璃进行说明。对与第一实施方式相同的结构标以相同的符号,有时省略对相同结构的说明。图9是第二实施方式的放大图,图10是沿图9中的X-X线的剖视图。
如图9所示,第二实施方式中,第一台座部14的台座缘部位于端子连接部42的缘部的正上方。第二实施方式与第一实施方式的不同即在于该结构。
导电体40具备端子连接部42、与端子连接部42的对置的长边中的一条长边连结的2个连结部43、以及与另一条长边连结的1个连结部43。导电体40具备共计3个连结部43。3个连结部43的宽度相等。
与第一实施方式相同,连结部43具有比端子连接部42的长度方向或横向方向的宽度窄的宽度。另外,导电体40的汇流条部41具有比连结部43的至少一部分宽的宽度。
不需要第一台座部14的台座缘部的全部都位于端子连接部42的缘部的正上方,只要台座缘部的90%以上位于端子连接部42的缘部的正上方即可。
图10示出带金属端子车辆用窗玻璃100中的玻璃板30、配置于玻璃板30上的遮蔽层70、配置于遮蔽层70上的端子连接部42、以及藉由焊料50与端子连接部42电连接的金属端子10的第一台座部14。
第一台座部14的台座缘部位于端子连接部42的缘部的正上方,因此焊料50在剖视下呈矩形形状。其结果是,可以像图10中用圆形标记包围所示那样使端子连接部42的缘部与焊料50的缘部一致,能够在玻璃板30上形成的遮蔽层70与遮蔽层70上形成的导电体40藉由无铅焊料连接后经过数日以上也能抑制遮蔽层或导电体40产生裂纹,能够抑制遮蔽层70下的玻璃板30的表面部分剥离。而且,通过使第一台座部14的台座缘部位于端子连接部42的缘部的正上方,也能确保金属端子10与导电体40的接合强度。
如图9所示,在俯视下,端子连接部42与连结部43以端子连接部42整周的30%以下连结。第二实施方式中,若使第一台座部14的大小和连结部43的连结部分的宽度与第一实施方式相同,则第二实施方式中端子连接部42的整周变长。其结果是,例如,在俯视下,端子连接部42与连结部43以端子连接部42整周的20%以下连结。

端子连接部42与连结部43的连结结构并不限于图11和图12,可以适当变更,只要第一台座部14的台座缘部位于端子连接部42的缘部的正上方即可。
(第三实施方式)
接着,对第三实施方式的带金属端子车辆用窗玻璃进行说明。对与第一实施方式和第二实施方式相同的结构标以相同的符号,有时省略对相同结构的说明。图13是第三实施方式的放大图,图14是沿图13中的XIV-XIV线的剖视图。
如图13所示,第三实施方式中,端子连接部42的缘部相对于第一台座部14的台座缘部在俯视下位于外侧,且相对于构成第一台座部14的台座缘部位于从第一台座部14离开的方向上不超过3mm的位置处。与第一实施方式和第二实施方式的不同即在于该结构。因此,构成第一台座部14的台座缘部与端子连接部42的缘部的距离小于3mm。
导电体40具有端子连接部42、与端子连接部42的对置的长边中一条长边连结的2个连结部43、以及与另一条长边连结的连结部43。导电体40具备共计3个连结部43。3个连结部43的宽度相等。

相对于构成第一台座部14的台座缘部位于从第一台座部14离开的方向上不超过3mm的位置处,因此焊料50的上底比下底短,在剖视下为大致梯形的形状。其结果是,可以像图14中用圆形标记包围所示那样使端子连接部42的缘部与焊料50的缘部一致,能够在玻璃板30上形成的遮蔽层70与遮蔽层70上形成的导电体40藉由无铅焊料连接后经过数日以上也能抑制导电体40产生裂纹,能够抑制遮蔽层70下的玻璃板30的表面部分剥离。而且,通过使端子连接部42的缘部相对于第一台座部14的台座缘部位于外侧、并且相对于构成第一台座部14的台座缘部位于从第一台座部14离开的方向上不超过3mm的位置处,也能确保金属端子10与导电体40的接合强度。

图15A至图15AF和图16G至图16I是示出第三实施方式的几个变形例的俯视图。在图15A至图15AF和图16G至图16I所示的各变形例中,端子连接部42的缘部都相对于第一台座部14的台座缘部位于外侧、并且相对于构成第一台座部14的台座缘部位于从第一台座部14离开的方向上不超过3mm的位置处。

(第四实施方式)
下面对第四实施方式的带金属端子车辆用窗玻璃进行说明。对与第一实施方式至第三实施方式相同的结构标以相同的符号,有时省略对相同结构的说明。

而第一台座部14的缘部相对于端子连接部42的其余部分缘部位于外侧。
因此,端子连接部42的缘部存在位于第一台座部14的外侧的部分和位于其内侧的部分。
图17A所示的端子连接部42在俯视下呈矩形。端子连接部42的一部分缘部(短边)位于超出第一台座部14的短边的位置处。而端子连接部42的缘部的其余部分(长边)位于比第一台座部14的长边更靠内侧的位置处。连结部43与端子连接部42的缘部的一部分(短边)和汇流条部41连结。
图17B所示的端子连接部42在俯视下呈椭圆形。端子连接部42的缘部的一部分(长轴侧)位于超出第一台座部14的短边的位置处。而端子连接部42的缘部的其余部分(短轴侧)位于比第一台座部14的长边更靠内侧的位置处。连结部43与端子连接部42的缘部的一部分(长轴侧)连结。
图17A和图17B所示的各变形例的形状也可以使端子连接部42的缘部与焊料50(未图示)的缘部一致,能够在玻璃板30上形成的遮蔽层70与遮蔽层70上形成的导电体40藉由无铅焊料连接后经过数日以上也能抑制导电体40产生裂纹,能够抑制遮蔽层70下的玻璃板30的表面部分剥离。而且,通过使端子连接部42的缘部的一部分相对于第一台座部14的台座缘部位于外侧、且相对于构成第一台座部14的台座缘部位于从第一台座部14离开的方向上不超过3mm的位置处,也能确保金属端子10与导电体40的接合强度。

端子连接部42与连结部43的连结结构并不限于图17A和图17B所示的变形例,可以适当变更,只要端子连接部42的缘部的一部分相对于第一台座部14的台座缘部位于外侧、且相对于构成第一台座部14的台座缘部位于从第一台座部14离开的方向上不超过3mm的位置处即可。
下面参照附图对本发明的另一形态的带金属端子车辆用窗玻璃进行说明。如图18所示,带金属端子车辆用窗玻璃200由具有接合第一玻璃板32和第二玻璃板33的中间膜34的夹层玻璃35构成。第一玻璃板32由第一实施方式~第四实施方式的各玻璃板构成,第二玻璃板33则由追加的玻璃板构成。作为一例,带金属端子车辆用窗玻璃200适用于车辆的挡风玻璃。对于带金属端子车辆用窗玻璃200,可以与带金属端子车辆用窗玻璃100同样地适用第一实施方式~第四实施方式。在将带金属端子车辆用窗玻璃200组装到车身上的情况下,第一玻璃板32配置于车外侧,第二玻璃板33配置于车内侧。而且,在第一玻璃板32的车内侧面上形成遮蔽层70,在遮蔽层70上形成导电体40。另外,也可以是第二玻璃板33由第一实施方式~第四实施方式中的各玻璃板构成,而第一玻璃板32则由追加的玻璃板构成。在第二玻璃板33由第一实施方式~第四实施方式中的各玻璃板构成、且将带金属端子车辆用窗玻璃200组装到车身上的情况下,在第二玻璃板33的车内侧面上形成遮蔽层70,在遮蔽层70上形成导电体40。
第一玻璃板32和第二玻璃板33可以适用与第一实施方式~第四实施方式中的玻璃板30相同的玻璃板。因此,第一玻璃板32和第二玻璃板33可以是未强化玻璃或强化玻璃中的任一种。第一玻璃板32和第二玻璃板33的厚度可以相同也可以不同。
例如,配置于车外侧的第一玻璃板32的板厚优选为1.1mm以上3.0mm以下。配置于车外侧的第一玻璃板32的板厚为1.1mm以上则耐飞石性能等的强度足够,为3.0mm以下则夹层玻璃35的质量不会变得过大,从车辆的油耗角度考虑是优选的。配置于车外侧的第一玻璃板32的板厚更优选为1.5mm以上2.8mm以下,进一步优选为1.8mm以上2.6mm以下。配置于车内侧的第二玻璃板33的板厚优选为0.5mm以上2.3mm以下。配置于车内侧的第二玻璃板33的板厚为0.5mm以上则操作性良好,为2.3mm以下则质量不会变得过大,因而优选。
另外,第一玻璃板32和第二玻璃板33中的任一方或双方也可以是在将夹层玻璃35组装到车身上的情况下厚度随着从下边侧(引擎盖侧)朝向上边侧(车顶侧)而变厚的楔形形状。
第一玻璃板32和第二玻璃板33例如通过浮法等成形为板状,通过重力成形或加压成形等在高温下弯曲成形。夹层玻璃35可以是在长度方向和短边方向这两个方向上弯曲的多曲形状。或者,夹层玻璃35也可以是仅在长度方向上弯曲的单曲形状、或仅在短边方向上弯曲的单曲形状。在夹层玻璃35弯曲的情况下,优选弯曲成朝向车外侧凸起。在夹层玻璃35弯曲的情况下,曲率半径优选为1000mm以上100000mm以下。第一玻璃板32和第二玻璃板33的曲率半径可以相同也可以不同。在第一玻璃板32和第二玻璃板33的曲率半径不同的情况下,第一玻璃板32的曲率半径比第二玻璃板33的曲率半径大。
中间膜34接合第一玻璃板32和第二玻璃板33。中间膜34除了由聚乙烯醇缩丁醛(PVB)构成的中间膜以外,特别是在要求耐水性的情况下,优选使用乙烯乙酸乙烯酯共聚物(EVA),还可以使用丙烯酸系光聚合型预聚物、丙烯酸系催化聚合型预聚物、丙烯酸酯·乙酸乙烯酯的光聚合型预聚物或聚氯乙烯等。中间膜34可以是单层结构或多层结构中的任一种。
在夹层玻璃35的周缘部,可以在整周上以带状形成黑色等暗色不透明的遮蔽层(未图示)。该遮蔽层可以设置于第一玻璃板32和第二玻璃板33双方,也可以仅设置于任一方。遮蔽层具有保护将夹层玻璃35粘接保持在车身上的聚氨酯密封剂等免于因紫外线而劣化的功能。
在带金属端子车辆用窗玻璃200中,在第二玻璃板33的周缘部形成有圆弧状的、以在第二玻璃板33的板厚方向上贯通的方式形成的挖空部36。在由挖空部36露出的第一玻璃板32的车内侧的表面上形成导电体40。在形成有遮蔽层的情况下,导电体40形成于遮蔽层上。
金属端子10的第一台座部14和第二台座部15藉由焊料50与配置于第一玻璃板32上的导电体40的端子连接部42(未图示)电连接。导线60与导电体40藉由金属端子10和焊料50电连接。
带金属端子车辆用窗玻璃200也适用与第一实施方式~第四实施方式中的带金属端子车辆用窗玻璃100同样的端子连接部42与台座部(第一台座部14和第二台座部15)的关系,因此能够在玻璃板30上形成的遮蔽层与遮蔽层70上形成的导电体40藉由无铅焊料连接后经过数日以上之后也能抑制遮蔽层70或导电体40产生裂纹,能够抑制遮蔽层70下的玻璃板30的表面部分剥离。进而,也能确保金属端子10与导电体40的接合强度。
在图18所示的实施方式的带金属端子车辆用窗玻璃100和第一实施方式~第四实施方式的带金属端子车辆用窗玻璃200中,虽然未图示,但通过导电体40,多个汇流条部41例如沿着玻璃板30的周缘部形成。金属端子10电连接到各汇流条部41,进而连接到电源的阳极和阴极。例如,配置连接各个汇流条部41之间的加热线。
加热线例如是微细的钨丝等丝线。该情况下,多根金属丝可以相互隔开配置,也可以是金属丝交叉而成的网眼形状。另外,也可以形成透明导电膜来代替加热线。透明导电膜例如可例示Ag膜等金属膜、ITO(氧化铟·锡)膜等金属氧化膜、或含导电性微粒的树脂膜。透明导电膜可以层叠多种膜。
以上对本发明的实施方式进行了说明,但本发明并不限定于以上示例,在不脱离本发明主旨的范围内能够进行各种改良或变形。带金属端子车辆用窗玻璃例如可适用于挡风玻璃、后玻璃、侧窗玻璃和三角窗玻璃。
