Plug, compressor and air conditioner

The invention discloses a plug, a compressor and an air conditioner, the plug comprises a plug whole shell, the plug whole shell comprises a fixed plate, the fixed plate is provided with pipe sleeve columns with the same number as at least two wires, a conductive sleeve is inserted in each pipe sleeve column, one end of each conductive sleeve is provided with an inner hole for a binding post to insert, the inner holes are matched with the binding posts, and the inner holes are matched with the binding posts; the other end of the conductive sleeve is connected with the wire; the assembling efficiency of the compressor is improved through the wiring mode of the plug, the operation steps of assembling and disassembling the compressor are simplified, meanwhile, the matching mode that the inner hole of the conductive sleeve is matched with the binding post is adopted, and the situation that poor contact is prone to occurring when wires and the binding post of the compressor are independently assembled in a one-to-
