第二连接件1120横向设置，第二连接件1120包括两个水平部1121 和一个弯曲部1122(即U型结构1102的闭口端)，弯曲部1122的两端分别固定连接两水平部1121，形成整体的U型结构1102。第二连接件1120竖直设置，U型结构1102的两个水平部1121位于同一竖直面内，两个水平部1121之间形成U型结构1102的开口端。线夹1101固定连接于U型结构1102的水平部1121上，位于水平部1121下方。线夹1101数量可以为一个、两个或多个，用于固定连接各分裂导线，当线夹1101的数量为两个或多个时，两个或多个线夹1101分别设置在两个水平部1121上，可以使得第二连接件1120的受力更加均匀。图1中线夹1101的数量为四个，两个水平部1121上分别设置两个线夹1101。第二连接件1120设置为U型，可以充分利用U型结构1102中两水平部1121之间的间隙将线夹挂接在不同的水平面内，从而实现多分裂导线的挂接；同时U型金具的封闭端类似于半个均压环的形状，可以在与复合横担连接的一侧实现较好的电场封闭效果，减少电场奇点的产生，降低异常放电发生的可能性。
线夹1101与第二连接件1120之间可以通过焊接、铆接、螺栓连接等方式进行连接，两者之间稳定连接即可，具体连接方式不做限制。
为了使得复合横担金具1100的整体结构更加稳定，在第二连接件1120的U型结构1102的开口端设置封盖1123，封盖1123固定连接两个水平部1121远离弯曲部1122的一端，在开口端形成良好的支撑，以使得整个连接更加稳定，同时封盖1123的设置使得第二连接件1120的U型结构1102成为一个相对封闭的结构，可以实现更好地电场屏蔽效果。封盖1123为矩形板，通过焊接、铆接、螺栓连接等方式与两个水平部1121固定连接。
在另一实施例中，参阅图2，复合横担金具1002包括一个第一连接件1110，一个第二连接件1120和两个第三连接件1130，第三连接件1130设置于第二连接件1120上，第二连接件1120水平设置，U型结构1102的两个水平部1121位于同一水平面内。两个第三连接件1130分别设置于U型结构1102的弯曲部1122的两端，两个第三连接件1130之间呈一定角度设置，以使得挂接于两个第三连接件1130上的斜拉绝缘子与 铁塔之间呈三角结构，从而使得整个支撑结构更加稳定。四个线夹1101分别设置于两个水平部1121上，位于水平部1121下方，两两对应沿导线前进方向排列，两个水平部1121上沿同一直线方向对应的两个线夹1101用于挂接同一根导线，可以实现对导线更高的握持力，从而将复合横担金具1002应用于小角度的转角塔上，无需使用跳线连接，大大降低小角度转角塔接线的复杂度。
当然，在其他对于受力要求不高的结构中，复合横担金具1002也可以只包括第一连接件1110和第二连接件1120，或者包括第一连接件1110、第二连接件1120和一个第三连接件1130，在此不作具体限制，可以根据实际情况进行选择。
参阅图1、图3和图4，为了增强复合横担金具的承力能力，更好地承受导线的拉力，更稳定的连接导线，本发明的另一实施例中，复合横担金具1100包括两个第一连接件1110和一个第二连接件1120，第二连接件包括至少两个U型结构1102和若干第四连接件1140。至少两个U型结构1102之间同向平行设置，并通过若干第四连接件1140相互连接，第四连接件1140的两端分别连接于两个U型结构1102中相对应的两个水平部1121上。图3和图4中均设置两个U型结构1102。
具体地，根据不同的需求，第四连接件1140可以是图3中所示的细长的圆柱或长方体结构，第四连接件1140为细长结构时，复合横担金具1100的整体重量较低，可以降低成本；第四连接件1140也可以是图4中的平板结构，第四连接件1140为平板结构时，复合横担金具1100的支撑更稳定，可靠性更高，这里对第四连接件1140的具体形状构造不作具体限制，可根据实际工况进行选取。
本实施例中，由于增加了第四连接件1140，线夹1101不仅可以设置于第二连接件1120的水平部1121上，还可以设置于第四连接件1140上，在此不作具体限制，以线夹1101分布及复合横担金具1100整体受力均匀合理为准。两个U型结构同向平行设置，每个U型结构的每个水平部1121上设置两个线夹，两个U型结构上的线夹两两对应沿导线前进方向排列，可以实现两个线夹对同一根导线进行固定。同时整个复合 横担金具1100还可以用于挂接四分裂导线，可以为更大电流容量的输电线路提供更好地提供支撑，可以在导线需要实现小角度转角的情况下，提高导线固定的可靠程度，可以省却转角塔的跳线结构，使得导线无需开断，降低施工复杂程度，提高线路可靠性。
本实施例中，弯曲部1122的封闭端与水平部1121的端部不在同一平面内，也即弯曲部1122倾斜连接在水平部1121上，两者不在同一平面内，且两个U型结构的弯曲部1122的封闭端相互远离，两个U型结构的弯曲部1122的封闭端之间的距离大于两个U型结构的弯曲部1122的开口端之间的距离，两个第一连接件1110分别连接于第二连接件1120的两个弯曲部1122的封闭端上，可以使得两个连接在复合横担金具1100上的复合横担之间呈三角结构，使得整个结构的支撑更加稳定。
由于线夹1101直接连接于复合横担金具1100上，两者之间的传力效果良好，并且两者之间距离较小，不存在风偏跳线问题，因此在导线进行小角度转角的情况下，导线可直接连接于线夹1101上，可以实现免跳线，导线免开断的结构，简化整体结构，便于安装。此时，线夹1101应当选取握持力较大的耐张线夹。
如图5所示，本发明还提供一种横担组件1000，包括两个支柱绝缘子1200、两个斜拉绝缘子1300和复合横担金具1100。
具体地，其中支柱绝缘子1200和第二连接件通过第一连接件固定连接，斜拉绝缘子1300和第三连接件固定连接，两个斜拉绝缘子1300设置于两个支柱绝缘子1200的上方，两个支柱绝缘子1200和两个斜拉绝缘子1300的组合可以对导线进行稳定支撑。
当然，在其他实施例中，如线夹只承受导线自重的情况下，横担组件可以为单柱式横担结构，仅包括一个支柱绝缘子；或者，横担组件也可以包括一个斜拉绝缘子、一个支柱绝缘子；在其他受力要求较高的情况下，横担组件还可以包括三个斜拉绝缘子和一个支柱绝缘子。横担组件所包括的斜拉绝缘子和支柱绝缘子的数量可以自由组合，这里不作具体限制。
本发明还提供一种输电塔(图未示)，包括塔身(图未示)和横担 组件1000。通过塔身与本申请中的各种实施例的不同组合，输电塔可以是直线塔也可以是小角度的转角塔，在此可以进行自由变换。
综上所述，本发明提供的一种复合横担金具、横担组件及输电塔，通过设计一种新型的复合横担连接金具，并且将导线线夹与复合横担连接件一体化设置，可以减小金具重量降低成本，同时有效减小导线与复合横担之间的距离，有效解决风偏跳线问题；U型结构的设计可以很好改善横担连接金具周围的电场分布；另外通过金具结构上的改进设计结合选取合适的线夹形式，提高金具的承力能力，使之适用于小角度的转角塔上，省却转角塔的跳线结构，使得导线无需开断，降低施工复杂程度，提高线路可靠性。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
