Platform door electrical plug mechanism for fixed-point connection

A platform door electrical plug mechanism for fixed-point connection comprises a sliding door electrical assembly, a sliding door connector, a platform power line, a platform plug connected with the platform power line and an electromagnetic lock, wherein the sliding door electrical assembly and the sliding door connector are fixed to a sliding door and connected with the sliding door. The electromagnetic lock is provided with a main lock cylinder which can be controlled to stretch out and retract, and the platform plug and the main lock cylinder are connected in a synchronous moving mode. When the sliding door connector is aligned with the platform plug, the main lock cylinder stretches out or retracts back and drives the platform plug to move upwards to be inserted into the sliding door connector or move downwards to be separated from the sliding door connector. The platform door electrical plug mechanism for fixed-point connection provides a novel interface on-off scheme for a fixed-point connection electr
