Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an end-protected fireproof cable. Background Art

[0002] The invention discloses an end-protected fireproof cable with publication number CN212033364U. After the cable is connected to the equipment housing, the installer moves the protective cover so that the inner wall of the protective cover abuts against the annular end face of the abutting ring away from the equipment housing. At this time, the open end of the protective cover abuts against the equipment housing. Then the installer rotates the clamping nut so that the clamping nut moves toward the equipment housing until the clamping nut abuts against the outer end face of the protective cover, thereby abutting against the open end of the protective cover, thereby strengthening the connection between the cable end and the equipment housing. When the cable is bent by external force, the position between the end of the insulating sleeve and the equipment housing is fixed and difficult to contact and wear, thereby extending the service life of the cable. When the clamping nut is tightened, the clamping nut abuts against the elastic sealing ring on the outer end face of the protective cover, thereby sealing the clamping nut and the outer end face of the protective cover, which is beneficial to prevent external moisture from entering the protective cover, thereby preventing cable leakage. The setting of the anti-wear ring enables flexible contact between the outer wall of the insulating sleeve and the opening of the connecting sleeve when the cable moves, further reducing the wear of the connecting sleeve on the outer wall of the insulating sleeve.

[0003] The above-mentioned end-protected fireproof cable cannot quickly disassemble and move the protection component when protecting the cable. When the cable section needs to be cut, the protection component is difficult to accurately protect the root of the cable, and the protection effect is poor. Utility Model Content
