Conductive busbar

Abstract

The invention discloses a conductive busbar, comprising a top portion. A pair of sidewalls are extended symmetrically from the bottom of the top portion, a clamp is arranged at the bottom of each sidewall, and an elastic jaw for clamping a contact wire is formed between the ends of the clamps; both opposing surfaces of the two sidewalls are provided with a plurality of ribs; each end of each sidewall is provided with a connection. The inner side of each sidewall of the conductive busbar is provided with self-locking positioning ribs to arrive at automatic positioning; when workers make connections, a middle connector is simpler and more convenient to mount, errors are avoided, and construction period is greatly shortened; the busbars can be automatically locked more firmly, and high- and low point micro-displacement due to vibrations is eliminated; the conductive busbar never strikes a pantograph under long-term working load, smooth passing of the pantograph is ensured, and safety andreliability are better.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a conductive bus bar. Background technique [0002] Electrified railways and urban rail transit generally use rigid catenary, that is, busbars made of aluminum alloy materials, to achieve mechanical and electrical connections. With the rapid development of urban rail transit, the quality and performance requirements of the busbar in the contact power supply system are getting higher and higher. The currently used bus bar has a simple structure and a smooth inner wall. When the bus bar is connected to the bus bar, it is fixed only by bolts and gaskets through the middle joint of the bus bar. Not only is it difficult to install, it is prone to errors, and the overall connection is not tight enough. The high and low points of the busbar will move slightly due to vibration. When the pantograph is in contact with it, an arc will be generated. Long-term use will cause the problem...

The currently used bus bar has a simple structure and a smooth inner wall. When the bus bar is connected to the bus bar, it is fixed only by bolts and gaskets through the middle joint of the bus bar. Not only is it difficult to install, it is prone to errors, and the overall connection is not tight enough. The high and low points of the busbar will move slightly due to vibration. When the pantograph is in contact with it, an arc will be generated. Long-term use will cause the problem of contact between the busbar and the pantograph, causing safety hazards
