[0002] The sealed cable entry device is a device that introduces the sealed cable into the electrical equipment without changing the explosion-proof performance of the equipment's explosion-proof type. It is an important part of the explosion-proof electrical equipment. The plug is fixed more firmly in the cable entry device, but the sealing ring is mostly made of rubber, which is prone to deformation in a low temperature environment, causing the sealing ring to shrink or the plug and the sealing ring to shrink at the same time, so it is difficult to ensure that the plug is fixed It is firm, reduces the service life of the equipment, increases the maintenance cost of the equipment, and cannot meet the needs of people
