Abstract
The utility model relates to a soft type flame-retardant, low-smoke and non-halogen silicon rubber cable, particularly the structural technology of a cable. The utility model comprises a flame-retardant, low-smoke and non-halogen silicone-rubber sheath layer in which two to thirty-six groups of insulated cable cores are arranged, and each groups of insulated cable cores are composed of a stranding soft-copper conductor and a flame-retardant, low-smoke, non-halogen silicone-rubber insulating layer arranged outside the stranding soft-copper conductor. A flat finished cable and a round cable can be produced by the utility model, and the utility model has the advantages of low smoke, non halogen, flame retardancy and soft performance. The minimum bending radius of the flat cable can reach as six times as thick of the thickness of a small edge, and the minimum bending radius of the round cable can reach as six times as thick of the diameter of the utility model. The utility model is more suitable for connecting moving electric appliances and equipment, and the utility model is convenient for laying and is hard to generate fracture.
Description
Technical field
The utility model relates to a kind of structure technology of cable.
Background technology
In order to adapt to the fire-fighting environmental protection requirement, cable should have low cigarette in the public place of crowd massing, Halogen, fire-retardant, can produce the cable that satisfies this requirement at present all is as the insulating sleeve material by similar high polymer such as polyvinyl chloride or polyethylene, and polyvinyl chloride or polythene material itself do not have low cigarette, Halogen, fire-retardant function, must add a large amount of opaque metal oxides such as magnesium hydroxide and just can produce low cigarette, Halogen, fire-retardant cable, and such cable product increases its hardness owing to add above composition, is not suitable for the connection of movable electrical appliances.So low cigarette, Halogen, fire resistance and the softness of present cable are one can not compatible contradiction.
The utility model content
The utility model purpose is to design a kind of silicone rubber for cable that has low cigarette, Halogen, fire-retardant and softness simultaneously.
The utility model comprises flame-retardant low-smoke halogen-free silicone rubber jacket layer is set, 2 to 36 groups of insulation cable cores are set in flame-retardant low-smoke halogen-free silicone rubber jacket layer, and every group of insulation cable core is made up of stranded soft copper conductor and the flame-retardant low-smoke halogen-free silicone rubber insulation layer that is arranged on outside it.
The utility model can be produced flat finished cable, also can produce round cable, have low cigarette, Halogen, fire-retardant and softness simultaneously, the minimum bending radius of flat cable can reach 6 times of little limit thickness, and the round cable minimum bending radius can reach 6 times of cable size.This cable is fit to the connection of movable electrical appliances, equipment more, and convenient auxilliary establishing is difficult for producing fracture.
In addition, the utility model is provided with screening braid between insulation cable core and flame-retardant low-smoke halogen-free silicone rubber jacket layer.Can realize shielding the needs of occasion.
When round cable, intact for product design is shaped, produce between each the group insulation cable core in screening braid the glass fibre inserts is set.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, flat cable is made up of seven groups of insulation cable cores, and every group of insulation cable core is made up of stranded soft copper conductor 2 and the flame-retardant low-smoke halogen-free silicone rubber insulation layer 3 that is arranged on outside it, squeezes flame-retardant low-smoke halogen-free silicone rubber jacket layer 1 in the outsourcings of seven groups of insulation cable cores.
As shown in Figure 2, round cable, form by four-line poem with seven characters to a line edge cable core, every group of insulation cable core is made up of stranded soft copper conductor 2 ' and the flame-retardant low-smoke halogen-free silicone rubber insulation layer 3 ' that is arranged on outside it, at seven groups of insulation cable cores one deck screening braid 4 is set, be filled with glass fibre inserts 5 between the four-line poem with seven characters to a line edge cable core in screening braid 4, squeeze flame-retardant low-smoke halogen-free silicone rubber jacket layer 1 ' in screening braid 4 outsourcings.
Claims (3)
1, soft type flame-retardant low-smoke halogen-free silicone rubber for cable, it is characterized in that comprising flame-retardant low-smoke halogen-free silicone rubber jacket layer is set, 2 to 36 groups of insulation cable cores are set in flame-retardant low-smoke halogen-free silicone rubber jacket layer, and every group of insulation cable core is made up of stranded soft copper conductor and the flame-retardant low-smoke halogen-free silicone rubber insulation layer that is arranged on outside it.
2,, it is characterized in that between insulation cable core and flame-retardant low-smoke halogen-free silicone rubber jacket layer, screening braid being set according to the described soft type flame-retardant low-smoke halogen-free of claim 1 silicone rubber for cable.
