The invention relates to the field of rail transit contact networks, and particularly discloses a lightweight busbar expansion element which comprises a pair of joint rows which are arranged in parallel, can relatively move and are used for clamping contact lines, an independent guide mechanism is arranged between the two joint rows, and relatively sliding parts on the guide mechanism are connected with the joint rows respectively. A conducting rod and a conducting seat are respectively fixed on the two joint rows, and the conducting seat can slide on the conducting rod; due to the fact that the guide mechanism is independently arranged, the two connector rows can be made of the same sectional material and are convenient to machine, the sliding guide piece is connected with the connector rows, and any one of the sliding guide piece and the connector rows can be replaced when damaged and is convenient to maintain. And meanwhile, the position relation can be adjusted during connection, so that the parallelism of the connector rows on the two sides can be adjusted in the installation process, and the situation that the requirement for the machining precision of the connector rows is high due to the fact that the sliding guide pieces and the connector rows are of an integrated structure, and the machining cost is further improved is avoided.
本发明涉及轨道交通接触网领域,具体公开了一种轻量化汇流排膨胀元件,包括一对平行设置且能相对移动用于夹持接触线的接头排,在两个接头排之间设置有独立的导向机构,所述的导向机构上相对滑动的部件分别与各接头排连接,在两个接头排上分别固定有导电杆和导电座,所述的导电座在导电杆上能够滑动;由于导向机构独立设置,两个接头排能够采用相同的型材方便加工,滑动导向件与接头排连接设置,其中任何一个被损坏都能够进行更换,方便维修;同时能够在连接时调整位置关系从而在安装过程中能够对两侧接头排平行度进行调整,还不会由于采用滑动导向件与接头排是一体式结构导致接头排加工精度要求高,而进一步提高加工成本。
