The invention relates to the technical field of power connection, in particular to a power terminal conversion connector which comprises a mounting plate, the mounting plate is connected with a side plate, the mounting plate is provided with a bottom rod and a connecting rod, the connecting rod is connected with a limiting rod, the limiting rod is connected with a pull rod, the pull rod is connected with a hasp, the side plate is connected with a connecting column, and a connecting block and a sliding rail are arranged in the connecting column. The connecting block is connected with a first-stage connector, a mounting hole is formed in the first-stage connector, and the mounting hole is connected with a wire hole. When the equipment is mounted, the mounting plate is fixed to a wall or a distribution box wall or other places through screws, the side plate is placed on the bottom rod, the fixing column is inserted into the fixing hole, then the connecting rod is rotated, the pull rod is stretched to enable the first-stage spring to enter a stretching state, the hasp is lapped on the side wall of the side plate, and then the equipment can be fixed; and the equipment can be taken down only by pulling the pull rod outwards and rotating upwards, so that the operation is convenient.
