Specific embodiment
Please refer to figs. 1 to 4, that show the specific structure of the preferred embodiment of the utility model, include
Cable 10 and elastic sealing element 20.
The cable 10 includes conducting wire 11, insulating layer 12, flame retardant coating 13, waterproof layer 14 and serving 15；The insulating layer
12 are wrapped in the outer surface of conducting wire 11.The flame retardant coating 13 is wrapped in the outer surface of insulating layer 12, in the present embodiment, flame retardant coating 13
For asbestos gauge, which increase the fire lines of this product.The waterproof layer 14 is wrapped in the outer surface of flame retardant coating 13, and which increase this productions
The waterproofness of product.The serving 15 is wrapped in the outer surface of waterproof layer 14, and serving 15 is that weather-proof PPS plastic cement or weather-proof PI are moulded
Glue avoids cable 10 under open-air atmosphere in use, the rotten cracking occurred.
The elastic sealing element 20 is closely sheathed on the outer surface of cable 10, and elastic sealing element 20 includes outside thread passing port
First sealing 21 of side, the second sealing 22 for blocking thread passing port outer end opening and close-fitting with thread passing port inner wall
