相关技术中，调光玻璃包括玻璃本体，玻璃本体的边缘电连接有导电部件，导电部件用于与外接电线电连接，以通过外接电线在玻璃本体上施加加载电压，同时通过调整加载电压的大小，实现玻璃本体透光率的调整。然而，在将导电部件与外接电线电连接时电连接效率低，从而降低了调光玻璃的安装效率。
图1示例了本公开实施方式提供的一种转接件3的俯视结构示意图。该转接件3用于实现导电部件2与外接电线4的电连接。导电部件2为任意结构件连接的需要与外接电线4连接的导电结构。示例地，导电部件2为调光玻璃的玻璃本体1连接的FPC(Flexible Printed Circuit board，柔性印刷电路板)或者金属导电片。
如图1-图4所示，该转接件3包括：底座31、导电机构32、第一压紧机构33和第二压紧机构34。底座31具有限位槽311，导电机构32限位在限位槽311内，导电机构32包括沿第一方向A分布且电连接的第一导电部321和第二导电部322，第一导电部321用于与外接电线4电连接；第一压紧机构33与底座31或导电机构32可拆卸的固定连接，第一压紧机构33和第二导电部322能够夹紧导电部件2；第二压紧机构34与底座31或导电机构32可拆卸的固定连接，用于将外接电线4按压至与第一导电部321抵接。
本公开实施方式中，通过第一导电部321与外接电线4的电连接，以及第二导电部322与导电部件2的电连接，实现外接电线4与导电部件2的电连接。其中，通过第二压紧机构34按压外接电线4至与第一导电部321抵接后，便于实现外接电线4与第一导电部321的电连接；通 过第二导电部322与第一压紧机构33的夹合，实现导电部件2与第二导电部322的电连接，从而在确保连接稳定性的同时，提高了导电部件2与外接电线4的连接效率。
其中，导电机构32、第一压紧机构33和第二压紧机构34中的一者与底座31可拆卸的固定连接。示例地，导电机构32与底座31可拆卸的固定连接，此时第一压紧机构33和第二压紧机构34可拆卸的固定连接在导电机构32上，或者可拆卸的固定连接在底座31上。也可以是第一压紧机构33、第二压紧机构34与底座31可拆卸的固定连接，此时导电机构32被第一压紧机构33或第二压紧机构34限位在限位槽311内。底座31、导电机构32、第一压紧机构33和第二压紧机构34中需要连接的两者可通过卡扣的方式或者螺钉固定的方式实现可拆卸连接。
本公开实施方式中，底座31可采用绝缘材料制成，以实现对导电机构32的绝缘防护，避免导电机构32发生漏电的情况。当然，底座31也可采用金属材料制成，以增加底座31的硬度，延长转接件3的使用寿命。此时为了实现对导电机构32的绝缘防护，可在限位槽311的内壁填充绝缘材料(比如环氧树脂等)，以实现导电机构32与底座31之间的绝缘。
对于导电机构32，第一导电部321与第二导电部322之间可通过单独设置的导电线实现电连接。示例地，导电线的一端通过螺钉与第一导电部321固定连接，导电线的另一端通过螺钉与第二导电部322固定连接。
当然，第一导电部321与第二导电部322之间也可通过导电基板324实现电连接，也即是如图3所示，导电机构32除了包括第一导电部321和第二导电部322之外，还包括导电基板324，第一导电部321和第二导电部322直接固定在导电基板324上，以通过导电基板324实现第一导电部321和第二导电部322的电连接。
其中，导电基板324、第一导电部321、第二导电部322可为一体式结构，以减少零部件的数量，同时保证第一导电部321和第二导电部322电连接的稳定性。
本公开实时方式中，通过转接件3实现导电部件2与外接电线4的 电连接时，导电部件2、外接电线4可沿限位槽311的槽口分别对应伸入至第二导电部322、第一导电部321的位置。当然，也可以在限位槽311的槽壁设置导向孔，此时导电部件2、外接电线4分别穿过对应的导向孔，伸入至第二导电部322、第一导电部321的位置。或者为便于外接电线4伸入限位槽311，限位槽311在第一方向上贯穿底座31。
对于设置导向孔的情况，示例地，如图2所示，限位槽311与第一方向A垂直的槽壁具有沿限位槽311的深度方向延伸的第一导向孔315，此时外接电线4可穿过第一导向孔315伸入限位槽311内第一导电部321对应的位置，且在第二压紧机构34的按压作用下沿限位槽311的深度方向移动，实现与第一导电部321的电连接；限位槽311与第二方向B垂直的槽壁具有第二导向孔316，此时导电部件2可穿过第二导向孔316伸入限位槽311内第二导电部322对应的位置。
其中，第一方向A与第二方向B不平行。示例地，第一方向A与第二方向B垂直。第二导向孔316至少高于第二导电部322的端面，以便于导电部件2沿第二导向孔316伸入限位槽311后，可直接搭接在第二导电部322上。
本公开实施方式中，如图3-图5所示，导电机构32还包括向远离底座31的方向延伸的导向槽323，第一压紧机构33还具有限位臂332，限位臂332穿过导向槽323，且与底座31可拆卸的固定连接。如此，在实现第一压紧机构33与底座31的固定连接时，可通过导向槽323与限位臂332的配合，实现对第一压紧机构33的导向，以保证第一压紧机构33与第二导电部322的精准配合，避免在夹紧导电部件2时出现松动的情况。
在一些实时方式中，如图3所示，导电机构32包括沿第一方向分布的两个导向槽323，相应地，如图5所示，第一压紧机构33具有沿第一方向分布的两个限位臂332，两个限位臂332能够分别穿过对应的导向槽332。如此，通过两个限位臂332和两个导向槽323的配合，以避免第一压紧机构33与底座31固定连接后在第一方向上的晃动。如图5所示，两个限位臂332位于固定部331的两侧。
在导向槽323和限位臂332的配合下，实现第一压紧机构33和第二导电部322对导电部件2的夹紧后，可将第一压紧机构33与底座31固定连接。
在一些实时方式中，如图6所示，底座31具有与导向槽323连通的通孔312，底座31的背面具有与通孔312连通的缺口313；限位臂332远离第一压紧机构33的一端具有限位部3321，限位臂332位于导向槽323和通孔312内，限位部3321可拆卸的限位在缺口313处，限位臂332在背离缺口313的方向上能够发生弹性形变。如此，可通过限位臂332的弹性形变，保证限位部3321可拆卸的限位在缺口313处。
其中，对于具有两个限位臂332的情况，两个限位臂332端部的限位部3321位置相对，底座31的背面是指底座31上与限位槽311的槽口所在的表面相背的面。
其中，为了便于第一压紧机构33的拆卸，在第一方向上导向槽323的尺寸大于限位臂332的尺寸，从而预留出限位臂332发生弹性形变的空间。如此，便于限位臂332向限位臂332背向限位部3321的一侧发生弹性形变，以在拆卸第一压紧机构33时，可在外力作用下促使限位臂332发生弹性形变，使限位部3321从缺口313处退出。
示例地，限位部3321为倒钩，此时在导向槽323的长度方向上倒钩的尺寸等于缺口313的尺寸，以保证倒钩限位在缺口313处后，倒钩与底座31的背面平齐，从而保证转接件3的美观性。
本公开实施方式中，通过第一压紧机构33与第二导电部322夹紧导电部件2时，可以是第二导电部322远离限位槽311槽底的端面直接与第一压紧机构33接触，以夹紧导电部件2。
其中，第二导电部322的端面近似平行于第一压紧机构33朝向第二导电部322的表面，以保证在夹紧导电部件2时对导电部件2的夹紧面积。
其中，在第二方向上第一压紧机构33的尺寸小于限位槽311的尺寸，或者第二导电部322远离限位槽311槽底的端面与限位槽311槽口平齐，以保证第一压紧机构33能够整体压紧在第二导电部322上，从而保证对 导电部件2的夹紧效果。
当然，如图4、图5或图6所示，也可以是第一压紧机构33朝向导电机构32的一侧具有固定部331。如此，在固定连接第一压紧机构33与底座31时，固定部331能够伸入限位槽311与第二导电部322进行配合，以避免第二导电部322高度不够，造成对导电部件2夹紧度不足的情况。
在第一压紧机构33具有固定部331的情况下，可通过如下三种情况实现对导电部件2的夹紧。
第一种情况：第一压紧机构33与底座31固定连接后，固定部331与第二导电部322沿第二方向分布且部分正对，导电部件2的部分区域夹紧在固定部331朝向第二导电部322的侧壁与第二导电部322朝向固定部331的侧壁之间。此时，固定部331与第二导电部322之间的间隙略小于导电部件2的厚度，以保证对导电部件2的夹紧效果。
其中，固定部331朝向第二导电部322的侧壁与第二导电部322朝向固定部331的侧壁近似平行，以保证对导电部件2的夹紧面积。示例地，固定部331和第二导电部322均为矩形块状结构。
第二种情况：第一压紧机构33与底座31固定连接后，在限位槽311的深度方向上，固定部331与第二导电部322局部正对，导电部件2的部分区域夹紧在固定部331朝向第二导电部322的端面与第二导电部322朝向固定部331的端面之间。此时，固定部331与第二导电部322之间的间隙略小于导电部件2的厚度，以保证对导电部件2的夹紧效果。
其中，固定部331朝向第二导电部322的端面与第二导电部322朝向固定部331的端面近似平行，以保证对导电部件2的夹紧面积。示例地，固定部331和第二导电部322均为矩形块状结构。
第三种情况：如图6所示，第二导电部322具有凹槽3221，固定部331伸入凹槽3221内，且能够将导电部件2的部分区域限位在凹槽3221内。
其中，固定部331伸入凹槽3221后，固定部331的结构与凹槽3221的结构匹配，以保证固定部331的侧壁与凹槽3221的槽壁之间的距离略小于导电部件2的厚度，和/或固定部331的端面与凹槽3221的 槽底之间的距离略小于导电部件2的厚度，以保证将导电部件2限位在凹槽3221内。示例地，固定部331为矩形块状，凹槽3221为与该矩形块状结构匹配的矩形槽。
当然，也可以是固定部331具有凹槽3221，第二导电部322能够伸入固定部331的凹槽3221内，本公开实施方式对此不再赘述。
对于上述三种情况，为了进一步保证对导电部件2的夹紧效果，且避免因夹紧力较大损坏导电部件2，同时保证导电部件2与第二导电部322直接接触，固定部331上用于配合第二导电部322的侧壁和/或端面具有泡棉垫，以通过泡棉垫的弹性缓冲，减小固定部331与导电部件2的硬性接触，同时提高对导电部件2的夹紧度。
另外，为了避免第一压紧机构33在第一方向上的晃动，对于上述第一种情况和第二种情况，可采取上述实施例描述的两个导向槽323配合两个限位臂332的结构；而对于上述第三种情况，还可通过固定部331与凹槽3221配合的结构实现，也即是在第一方向上固定部331的尺寸等于凹槽3221的尺寸。
本公开实施方式中，外接电线4可通过焊接的方式与第一导电部321电连接，也可通过固定螺钉与第一导电部321电连接。对于焊接或者固定螺钉实现电连接的情况，连接效率慢，且外接电线4具有内部导线和包裹内部导线的绝缘层，如此都需要先剥去外接电线4的绝缘层实现内部导线与第一导电部321的电连接，从而降低了外接电线4与第一导电部321的电连接效率。
如此，在一些实施方式中，如图3所示，第一导电部321包括导电片3211，导电片3211具有剪切槽3212和容置部3213，剪切槽3212、置部均沿所第一方向贯穿导电片3211；剪切槽3212的槽底与容置部3213连通，剪切槽3212的宽度从槽口到槽底逐渐减小，容置部3213在剪切槽3212的宽度方向上的最大尺寸大于剪切槽3212槽底的宽度，第二压紧机构34按压外接电线4时，剪切槽3212用于剪破外接电线4的绝缘层，且外接电线4的内部导线能够限位在容置部3213内。其中，剪切槽3212的宽度是指在第二方向上的尺寸。
如此，在实现外接电线4与第一导电部321的电连接时，可通过第二压紧机构34对外接电线4的按压，实现外接电线4与第一导电部321的电连接，避免了外接电线4剥皮的操作，以及外接电线4的焊接作用，提高了外接电线4与第一导电部321的电连接效率。
其中，剪切槽3212的宽度和容置部3213的腔体直径可根据外接电线4的外径和内部导线的外径设置。示例地，剪切槽3212槽口的宽度大于外接电线4的外径，剪切槽3212槽底的宽度略小于外接电线4的内部导线的外径，以保证能够完全剪破外接电线4的绝缘层。示例地，容置部3213可为两端开口的圆筒状结构，以与外接电线4的内部导线外形匹配，容置部3213的直径略小于外接电线4的内部导线的外径，以保证外接电线4的内部导线能够限位在容置部3213内，从而保证导电片3211与外接电线4的内部导线电连接的稳定性，避免虚接的现象。
其中，通过剪切槽3212剪破外接电线4的绝缘层，导电片3211具有位于剪切槽3212槽壁的切割刃，切割刃的数量为一个或一对。
示例地，如图3所示，导电片3211具有第一切割刃3214和第二切割刃3215；第一切割刃3214和第二切割刃3215均沿剪切槽3212的深度方向对称固定在剪切槽3212的槽壁，第一切割刃3214和第二切割刃3215沿背向槽壁的方向逐渐变薄。
另外，本公开实施方式中，如图3所示，第一导电部321包括多个导电片3211，且多个导电片3211沿第一方向间隔分布。如此，通过多个导电片3211即可与外接电线4形成多个连接点，以保证外接电线4与第一导电部321电连接的准确性，另外多个导电片3211的间隔分布，能够保证切割刃在切割外接电线4的绝缘层时，相邻两个导电片3211之间存在外接电线4的绝缘层沿轴向的形变空间，从而便于切割刃对绝缘层的切割。
可选地，如图3所示，第一导电部321还包括连接杆3216，多个导电片3211均与连接杆3216固定连接，以实现多个导电片3211的一体化，避免任一导电片3211在第一方向上发生弯折的情况。
本公开实时方式中，第一压紧机构33与第二压紧机构34可为一体 式结构，当然也可为分体式结构。当第二压紧机构34与第一压紧机构33为一体式结构时，则只需要一次安装即可实现第一导电部321与外接电线4的电连接，同时实现第二导电部322与导电部件2的电连接。
当第二压紧机构34与第一压紧机构33为分体式结构时，第二压紧机构34可采用与第一压紧机构33相同的装配方式与底座31固定连接。当然，第二压紧机构34也可采用其他装配方式与底座31固定连接，示例地，如图2，以及图7或图8所示，第二压紧机构34具有旋转轴341，限位槽311的槽壁具有贯穿的限位孔314，旋转轴341可旋转的限位在限位孔314内。
其中，第二压紧机构34可在第一位置和第二位置之间进行旋转切换，当第二压紧机构34位于第一位置时，便于外接电线4伸入第一导电部321的位置，当第二压紧机构34位于第二位置时，能够实现将外接电线4按压至与第一导电部321抵接。
第二压紧机构34扣接在底座31上，且通过与底座31的背面的限位，实现与底座31可拆卸的固定连接，从而便于在旋转至第二位置时与底座31的固定连接。可拆卸固定连接的方式可参考上述第一压紧机构33与底座31可拆卸固定连接的方式。
其中，在第二压紧机构34旋转至第二位置，也即是旋转至与底座31固定连接后，为了保证转接件3整体的美观性，如图2所示，限位槽311的槽臂具有避让区317，如此能够保证第二压紧机构34的上表面与底座31上限位槽311的槽口所在的一侧的面平齐。
在一些实施方式中，如图6或图8所示，第二压紧机构34具有按压块342；外接电线4的内部导线限位在容置部3213内时，按压块342位于剪切槽3212靠近第二导电部322的一侧，或者远离第二导电部322的一侧。
其中，按压块342背向第二压紧机构34的端面能够抵接限位槽311的槽底，以通过按压块342在限位槽311的深度方向上压紧外接电线4，避免外接电线4从导电片3211上脱落的情况，从而保证外接电线4与导电片3211电连接的稳定性。
其中，在通过按压块342按压外接电线4时，为了避免外接电线4 出现弯折的情况，可在剪切槽3212的两侧同时按压外接电线4。示例地，如图6所示，第一导电部321包括多个导电片3211，多个导电片3211中具有第一导电片和第二导电片，第二导电片位于第一导电片和第二导电部322之间；第二压紧机构34具有多个按压块342，外接电线4的内部导线限位在容置部3213内时，多个按压块342中的第一按压块位于第一导电片的剪切槽3212和第二导电片的剪切槽3212之间，多个按压块342中的第二按压块位于第二导电片的剪切槽3212靠近第二导电部322的一侧。
如此，通过第一按压块和第二按压块在第二导电片的两侧同时按压外接电线4，以避免外接电线4发生弯折。
进一步地，多个按压块342中还包括第三按压块，外接电线4的内部导线限位在容置部3213内时，第三按压块位于第一导电片背向第二导电部322的一侧，从而结合第一按压块和第二按压块在第一导电片的两侧和第二导电片的两侧对外接电线4进行按压，保证外接电线4整体被按压至容置部3213内。
在另一些实施方式中，第一导电部321为块状结构，第二压紧机构34还具有剪切部，第二压紧机构34与底座31固定连接时，剪切部与第一导电部321能够在第一方向上错位配合，以剪破外接电线4的绝缘层，外接电线4的绝缘层被剪破后内部导线夹紧在第一导电部321与剪切部之间。如此，在实现外接电线4与第一导电部321电连接的同时，避免外接电线4从第一导电部321上脱落的情况。
其中，第二压紧机构34与底座31固定连接时，剪切部位于第一导电部321背向第二导电部322的一侧，或者靠近第二导向部322的一侧。
其中，第二压紧机构34与底座31固定连接后，剪切部朝向第一导向部321的侧壁具有横截面为半圆形的通槽，且该通槽的半径略小于外接电线4的内部导线的半径。从而保证剪切部配合第一导电部321时能够剪破并取出外接电线4的绝缘层。
对于第二压紧机构34可旋转连接的情况，第一导电部321的剪切面和剪切部的剪切面均为开口朝向第二压紧机构34的旋转轴341的圆弧面。其中，第一导电部321的剪切面的曲率与剪切部的剪切面的曲率相等， 以保证在剪破外接电线4的绝缘层的同时通过第一导电部321和剪切部夹紧外接电线4。
本公开实施方式中，如图3和图4所示，导电机构32包括两个第一导电部321，两个第一导电部321沿第一方向对称分布在第二导电部322的两侧；转接件3包括与两个第一导电部321一一对应地的两个第二压紧机构34。如此，基于两个第一导电部321的设置，转接件3能够实现导电部件2与两根外接电线4的电连接，进而可通过多个转接件3实现多个导电部件2的串联。
图9示例了本公开实施方式的一种调光玻璃的结构示意图。如图9所示，该调光玻璃包括：玻璃本体1、导电部件2和上述实施方式所述的转接件3；导电部件2的一端与玻璃本体1电连接，导电部件2的另一端夹紧在第二导电部322与第一压紧机构33之间。
本公开实施方式中，导电部件2与外接电线4电连接时，通过转接件3包括的第一压紧机构33与第二导电部322的配合即可夹紧导电部件2，实现导电部件2与第二导电部322的电连接，从而提高了导电部件2与第二导电部322的连接效率，之后在将外接电线4与第一导电部321电连接，即可实现导电部件2与外接电线4的电连接，从而提高调光玻璃与外接电线4的电连接的效率，提高调光玻璃的安装速率。
其中，导电部件2为金属导电片，由于金属导电片自身的特性，避免了导电部件2的损坏，延长了调光玻璃的使用寿命。示例地，导电部件2为金属铝片。另外，对于金属导电片，为了避免在玻璃本体1的多层结构压合时因金属导电片过厚而产生气泡，金属导电片的厚度大于或等于0.5.毫米，且小于或等于3毫米。
在一些实施方式中，如图9所示，玻璃本体1电连接有多个导电部件2，此时结合上述实施方式，此时可通过多个转接件3实现玻璃本体1的多个导电部件2的串联。在另一些实施方式中，如图10所示，调光玻璃包括多个玻璃本体1，多个玻璃本体1分别电连接有导电部件2，此时可通过多个转接件3实现多个玻璃本体1的导电部件2的串联。
对于上述两种实施方式，外接电线4沿第一方向与转接件3的第一导电部321电连接，导电部件2沿与第一方向垂直的方向与转接件3的第二导电部322电连接，以保证串联后外接电线4沿玻璃本体1的侧边布置，同时避免导电部件2或者外接电线4的弯折，避免了布线繁琐的问题。
