Summary of the invention
Technical problem to be solved in the utility model is that the protective device of the cable end of a kind of sealing, good waterproof performance is provided.
The technical scheme that the utility model adopts is: a kind of protective device of cable end comprises drawing head, rubber tube and pyrocondensation sealed tube; Described rubber tube one end is fastening by clip and the sealing of drawing head main body, and the outer peripheral face of the other end of rubber tube and cable inner sheath is combined closely; Described pyrocondensation sealed tube is coated on the outer peripheral face of drawing head, rubber tube and cable jacket.
Described drawing head comprises drawing head the first main body, ring flange, core traction terminal and drawing head the second main body; Described drawing head the first main body is the column type cavity, and its inwall is provided with internal thread; Described ring flange edge is provided with drawing head the first main body inner wall the suitable external screw thread of internal thread is set; It is fixing on ring flange by nut that described core traction terminal passes ring flange, and described ring flange is threaded with the inner cavity wall of drawing head the first main body; The outer peripheral face of described drawing head the second main body is formed with the groove of fixing hoop, and drawing head the second main body and drawing head the first main body are welded as a whole.
Perforation number on described ring flange is identical with the number of cable core, and the interior crimping of cavity that cable core penetrates core traction terminal connects as one.
Described drawing head is steel material; The material of rubber tube is industrial rubber or latex, and the rubber tube inwall is coated with waterproof gasket cement.
The beneficial effects of the utility model are: rubber tube is connected and sealed the inner sheath of the heart yearn in the cable metal drawing head and cable, guarantees that the cable metal drawing head is to the water-tight performance of the heart yearn cable of removing inner sheath in the cable laying process; Effectively avoid the infiltration of moisture in cable sheath and cable core, effectively guaranteed the useful life of installation quality and the cable of cable, effectively improved the operating efficiency of cable construction.
