绝缘层3包覆于芯棒1上，套筒2的左右两侧均设有绝缘层3。绝缘层3包覆芯棒1裸露的部分，避免雨水等对芯棒1的腐蚀。本实施例中，绝缘层3为硅橡胶材料，具有良好的耐老化性能和憎水迁移性，可降低污闪和雨闪概率。
芯棒1的两端分别安装导线固定端子4，导线固定端子4用于固定导线，通过捆绑工艺可将导线固定在导线固定端子4上，或者也可以设置压盖将导线固定。
横担100通过连接耳固定连接过渡板200。套筒2上的连接耳可通过螺栓与过渡板固定连接。通过连接耳实现横担100与过渡板200的连接，便于拆装，当横担的组件需要更换时，方便维修，避免了在芯棒上打孔。如果套筒2与过渡板200通过胶水粘接，强度不足，在户外的各个环境中，胶水可能失效，影响横担组件的使用寿命。如果套筒2与过渡板200通过焊接固定，焊接可能引起套筒2或过渡板200的变形，对套筒2内的芯棒1造成损伤，影响芯棒1的使用寿命。
以下通过实施例进行更详细的说明。
实施例1
如图1A～图4所示，本实施例的横担组件中，过渡板200的两个相对的侧壁上均设有卡槽201，过渡板200的内部中空。卡槽201的上方和下方分别设有连接孔202。
套筒2的上表面和下表面分别设有连接耳，连接耳为第一连接耳21。套筒2的上表面和下表面左右对称设置第一连接耳21，第一连接耳21的数量共为四个。第一连接耳21由套筒2的上表面向上延伸或由下表面向下延伸。第一连接耳21上设有连接孔212。套筒2安装在卡槽201内，连接孔202和连接孔212相对应，第一连接耳21与过渡板200的侧壁通过螺栓固定连接，螺栓穿过连接孔202和连接孔212。
可选的，如图4所示，第一连接耳21与过渡板200的侧壁通过螺栓连接时，第一连接耳包括两个平行的翻边211，螺栓安装在两个翻边211之间。两个翻边211之间的距离B大于螺栓的螺帽的内切圆直径d，小于螺栓的螺帽的外接圆直径D。在对螺栓进行紧固时，两个翻边211可卡住螺帽，便于对螺栓的紧固，提高工作效率。
可选的，本实施例中，横担组件还包括顶相横担300，顶相横担300的顶端设有挂线端子301，挂线端子301用于固定导线。过渡板200的顶部设有连接孔204，顶相横担300通过螺栓及连接孔204固定在过渡板200的上表面上。横担组件设置顶相横担300使得横担组件可用于三相输电导线的架设。
如图3所示，过渡板200的背部设有两条平行的三角垫块203，两条三角垫块203沿竖直方向延伸，三角垫块203的截面为三角形。在过渡板200安装到杆体上时，三角垫块203可对过渡板200起到支撑的作用。两条三角垫块203之间设有间隙，使得过渡板200可安装到不同型号的杆体，杆体的截面为矩形或圆形均可。通过设置三角垫块203，提高了横担组件的通用性。
过渡板200上设有安装孔205，安装孔205位于两条三角垫块203之间。本实施例中，安装孔205位于过渡板200的竖直中心线上，安装孔205用于将过渡板200固定到杆体上。三角垫块203外侧的斜边与过渡板200背面的边缘固接，使得过渡板200的结构简单，还可降低成本。
可选的，导线固定端子4包括卡合部41和挂线部42，卡合部41设有水平开口的套接槽43。芯棒1的端部插入套接槽43内，与套接槽43卡合固接，实现芯棒1与导线固定端子4的连接。挂线部42连接在卡合部41的顶端，挂线部42顶部设有固定导线的槽。本实施例的导线固定端子4的挂线部可以是实心的，也可以是空心的，使用时根据实际需求进行选择。
本实施例中，导线固定端子4还包括挂环44，挂环44为“L”形。挂 环44于挂线部42的下方，挂环44的一端连接挂线部42的下表面，另一端连接卡合部41的侧壁，挂环44与卡合部41、挂线部42形成一个闭合的环。在安装导线或维修线路时，挂环44可用于悬挂工具，便于工人操作。另一种方案中，挂环44可两端都连接于挂线部42。
芯棒1的截面为矩形，矩形的芯棒1可避免芯棒1在套筒2内发生不必要的旋转，结构更牢靠。相同的受力情况下，矩形截面的材料用量少。芯棒1可以是实心，也可以空心，根据实际情况进行选择。
实施例2
如图5所示，本实施例的横担组件与实施例1的结构相近，不同之处在于，为了便于架设三相输电导线，本实施例没有使用顶相横担，而是在横担上增设了中相导线固定端子5。中相导线固定端子5与导线固定端子4之间有一定的距离，可保证相邻导线之间的安全距离。
为了方便中相导线固定端子5的安装，绝缘层3包括长绝缘层31和短绝缘层32。长绝缘层31位于套筒2的一侧，多个短绝缘层32位于套筒2的另一侧，本实施例中短绝缘层32的数量为两个。中相导线固定端子5位于相邻的短绝缘层32之间，中相导线固定端子5通过卡箍或者压接的方式固定在芯棒1上。中相导线固定端子5的顶部为挂线部，用于导线的固定。
实施例3
如图6和图7所示，本实施例横担组件的结构与实施例1相近，不同之处在于，本实施例过渡板的前壁延伸出水平的上连接板206和下连接板207。上连接板206和下连接板207之间设有间隙。
套筒2的上表面和下表面分别设有连接耳，连接耳为第二连接耳22。第二连接耳22上设有竖直方向的连接孔221，第二连接耳22通过连接孔 221与过渡板连接。套筒2安装在上连接板206和下连接板207之间，上方的第二连接耳22与上连接板206固定连接，下方的第二连接耳22与下连接板207固定连接。
本实施例的横担组件，结构更简单，便于安装。
实施例4
如图8所示，本实施例的横担组件与实施例3的结构相近，不同之处在于，为了便于架设三相输电导线，本实施例没有使用顶相横担，而是在横担上增设了中相导线固定端子5。
为了方便中相导线固定端子5的安装，绝缘层3包括长绝缘层31和短绝缘层32。长绝缘层31位于套筒2的一侧，多个短绝缘层32位于套筒2的另一侧，本实施例中短绝缘层32的数量为两个。中相导线固定端子5位于相邻的短绝缘层32之间，中相导线固定端子5通过卡箍固定在芯棒1上。中相导线固定端子5的顶部为挂线部，用于导线的固定。
实施例5
如图9和10所示，本实施例横担组件的结构与实施例1相近，不同之处在于，本实施例的过渡板的前壁上设有固定板208，固定板208包括水平部2081和竖直部2082，水平部2081的一端连接过渡板的前壁，另一端连接竖直部2082。竖直部2082与过渡板的前壁之间形成一个开放的容腔。竖直部2082下方可设置肋板2083，以增强固定板208的强度。
套筒2的下表面设有连接耳，连接耳为第三连接耳23，第三连接耳23上设有水平的连接孔231，连接孔231用于与过渡板的连接。套筒2安装在竖直部与过渡板的前壁之间，第三连接耳23与固定板208通过螺栓及连接孔231固定连接。
本实施例的横担组件，螺栓的用量少，结构强度更高。
实施例6
如图11所示，本实施例的横担组件与实施例5的结构相近，不同之处在于，为了便于架设三相输电导线，本实施例没有使用顶相横担，而是在横担上增设了中相导线固定端子5。
