Ultrathin power converter

The utility model relates to the technical field of power converters, and discloses an ultrathin power converter. According to the utility model, the pull ring is held by a hand to be pulled upwards, the pull ring drives the cover plate to be separated from the fixed frame when being pulled upwards, and after the cover plate is taken down, the wire body of the wire harness is placed into the fixed frame and is clamped into the wire passing groove at the top of the fixed frame; when excessive wire bodies on the wire harnesses are stored in the fixing frame, the cover plate is clamped on the fixing frame again, the function of storing the connecting wire harnesses can be achieved, cleanliness of a table top is guaranteed, winding of the wire harnesses is avoided, practicability is high, meanwhile, heat generated during operation of the converter body can be preliminarily dredged through cooperation of the cooling fins, and the service life of the converter body is prolonged. And when the heat is still raised, t
