Protecting cover structure of compressor overload protector

Abstract

Disclosed is a protecting cover structure of a compressor overload protector. A compressor comprises an electric mechanism and a compression mechanism, the electric mechanism is mounted on the upper portion of a sealed container, the compression mechanism is mounted on the lower portion of the sealed container, the sealed container consists of an upper cover, a shell and a lower cover, a wiring terminal, an overload protector, a mounting column and a protecting cover are mounted on the upper cover of the compressor, the mounting column penetrates through the protecting cover, the protecting cover comprises a hollow cover body, two barrels with different heights are connected to form the hollow cover body, the cover body is provided with a positioning hole at a joint of the two barrels, and a hollow heat-insulation protecting sleeve is formed below the positioning hole. The heat-insulation protecting sleeve can prevent an outer cover of a power cord from directly contacting with the mounting column, and accordingly electric leakage due to the fact that the outer cover of the power cord is heated and melted and a series of accidents caused by the electric leakage are prevented.

Description

technical field [0001] The invention belongs to the field of compressors for air conditioners, and in particular relates to a protective cover structure of a compressor overload protector which is provided with a heat-insulating protective cover and can prevent the skin of a power line from being heated and melted. Background technique [0002] Generally speaking, a compressor is a part of a refrigeration cycle device, and it is a device that pressurizes a refrigerant to make the pressure and temperature of the refrigerant suitable for a specific purpose. The refrigeration cycle device consists of a compressor, a condenser, an expansion device, and an evaporator, and all components are connected to each other to form a closed circulation system. [0003] This refrigeration cycle device compresses the low-temperature and low-pressure refrigerant gas sucked into the compressor, and discharges it in a high-temperature and high-pressure state. When the discharged refrigerant gas...

AI Technical Summary

Problems solved by technology

[0013] The rotary compressors in the prior art have the following problems: the existing compressor terminals, overload protectors and power cords connected to them are all installed in a protective cover with a narrow space, and the power cords directly contact the mounting columns, and the long After a long time of use, the skin of the power cord will be heated and melted, resulting in leakage and accidents
