[0002] In the electrified railway system, the high-voltage rail plays a vital role as part of the current loop. The current is transmitted from the power supply system to the train through the contact network, and then flows back to the substation through the high-voltage rail to form a complete current loop; therefore, the connection and power supply between the high-voltage rails are the key to realizing this function.

[0003] The connection and power supply devices currently used still have the following problems: 1. The left and right positions of the high-voltage rail need to be adjusted during connection, which makes it impossible to quickly install the connection structure and reduces the connection efficiency. In addition, the bolt holes are prone to misalignment, which is not conducive to the rapid insertion of the bolts. 2. The outer wall of the high-voltage rail is prone to rust, and the rust on the outer wall of the high-voltage rail cannot be automatically removed during connection, which affects the subsequent power connection effect.
