Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a fireproof cable of high flame retardant property, includes cable body 1, and cable body 1 is including outer 2 and conductor body 3, and outer 2 is including insulating layer 4 and fire-retardant layer 5 and

insulating layer

6, and 5 fixed connection on fire-retardant layer are in the rear side of

insulating layer

4, and 6 fixed connection on insulating layer are in the rear side on fire-retardant layer 5.

The main material of insulating layer 4 is rubber, insulating layer 4 mainly forms through rubber and other various built-up agent combinations, later stage rethread heating, vulcanize, a relatively elasticity of formation is suitable for the cable wire of frequent movement, the operating temperature that insulating layer 4 allowed this moment can reach 90 degrees simultaneously, the characteristics of having possessed the weather resistance, through setting up insulating layer 4, and then the effectual influence that causes in use between conductor 3 and other conductors 3 that prevents in the cable body 1, and then the effectual stable effect that has improved whole device in use.

The main material on fire-retardant layer 5 is polyvinyl chloride, can be effectual has fire-retardant effect to cable body 1 through polyvinyl chloride, prevents that conductor 3 from can be fire-retardant to the burning things which may cause the source of a fire when the phenomenon that ages and catch fire after long-term the use, the effectual safety in utilization that improves cable body 1.

The main material of insulating layer 6 is PTFE colloquially called the iron fluorine dragon, consequently, insulating layer 6 has fine high temperature resistant thermal-insulated effect, through setting up insulating layer 6, the heat that makes conductor 3 produce when using can carry out the separation, prevent the outside perception at cable body 1 to the heat, and then the influence is to cable body 1's use, through blockking the heat that produces conductor 3, make the condition that a plurality of cable bodies 1 can not produce the high temperature when using simultaneously, whole device's safety in utilization and stable effect have further been improved.

A plurality of logical grooves 7 have been seted up to outer 2's outside, a plurality of structures homogeneous phase that lead to in the groove 7, slide 8 has all been seted up to the front and back inner wall that leads to groove 7, equal sliding connection has a plurality of smooth balls 9 in two slide 8, specific quantity is decided according to actual conditions, fixedly connected with connecting block 10 between a plurality of smooth balls 9, connecting block 10 is leading to inslot 7 sliding connection, connecting block 10 is leading to inslot 7 horizontal slip, the bottom fixedly connected with spacing ring 11 of connecting block 10, spacing ring 11 is located conductor 3, the inside copper line 12 that is provided with of spacing ring 11, the front side fixedly connected with fixture block 13 of spacing ring 11, draw-in groove 14 has been seted up to the rear side of spacing ring 11, fixture block 13 is at 14 internal sliding connection of draw-in groove, fixture block 13 is at another spacing ring 11 internal slip of draw-in groove 14.

When copper line 12 changes in the conductor 3 when needs, move connecting block 10 left, connecting block 10 moves left and drives slide ball 9 and slide in slide 8, connecting block 10 moves left and drives spacing ring 11 and move left simultaneously, spacing ring 11 moves left and drives fixture block 13 and move left from draw-in groove 14 on other spacing ring 11, spacing ring 11 moves left and drives inside copper line 12 and move left, copper line 12 is smooth at this moment shifts out from cable body 1, and then can be convenient for change copper line 12, after finishing changing copper line 12, promote connecting block 10 right and unanimous with above motion principle, and then make copper line 12 reset.
