Description

technical field

[0001] The invention relates to a cable lead-in device, in particular to a cable lead-in device for a plug-in cable protection tube. Background technique

[0002] At present, the structure of the known explosion-proof cable entry device is composed of an entry device body, a compression nut, a rubber sealing ring, an O-ring and a lock nut. First screw the body of the lead-in device into the target housing so that the threads are fully screwed into the compression O-ring or reversely tighten the compression O-ring with the compression nut, then pass the cable through the compression nut, rubber sealing ring, and screw Tighten the compression nut to compress the rubber sealing ring to achieve the purpose of the rubber sealing ring holding the cable tightly. However, the O-ring of this cable entry device is installed in the undercut groove, and it is easy to damage the O-ring and then destroy the sealing structure when tightening; the sealing ring is a cylindri...
