The invention provides an anchor section joint of an overhead rigid contact net for quick rail transit, which comprises busbar terminals, a contact line, an electric connection assembly and an insulator; the two busbar terminals are opposite in orientation, arranged in parallel and partially overlapped; the contact line is fixed to the lower end face of the busbar terminals; the busbar terminals are connected through the electric connection assembly, the busbar terminals are suspended at the lower end of the insulator through lengthened busbar positioning wire clamps, and fixed-distance sliding blocks are arranged between the contact surfaces of the busbar terminals and the lengthened busbar positioning wire clamps and are fixed on the busbar terminals. Each suspension point of the busbar terminals is provided with a fixed-distance sliding block, and the fixed-distance sliding blocks can freely slide in the lengthened busbar positioning wire clamps along with the busbar terminals, so it is guaranteed that when busbars expand with heat and contract with cold, the actual span within the mechanical segmentation range is not changed, and the uniformity of rigid suspension static elasticity when a pantograph is subjected to mechanical segmentation is guaranteed.
本发明提供了一种快速轨道交通架空刚性接触网锚段关节,包括汇流排终端、接触线、电连接组件和绝缘子,两个所述汇流排终端朝向相反、平行设置且部分重叠,所述接触线固定于所述汇流排终端的下端面上,所述汇流排终端间通过电连接组件连接,所述汇流排终端通过加长型汇流排定位线夹悬挂于绝缘子下端,所述汇流排终端与加长型汇流排定位线夹的接触面间设置有定距滑块,所述定距滑块固定于汇流排终端上。本发明的汇流排终端在每个悬挂点处设置定距滑块,能随汇流排终端在加长型汇流排定位线夹中自由滑动,保证汇流排热胀冷缩时,机械分段范围的实际跨距不发生改变,确保受电弓通过机械分段时刚性悬挂静态弹性的均匀性。
