Brief description of the drawings
Fig. 1 is the structural representation of a kind of fire-resistant shield type motor-car control cables that the utility model proposes;
Fig. 2 is the structural representation of the disclosed core of a kind of fire-resistant shield type motor-car control cables that the utility model proposes.
Detailed description of the invention
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with accompanying drawing, specific embodiment is described in detail.
As shown in Figure 1, Fig. 1 is the structural representation of a kind of fire-resistant shield type motor-car control cables that the utility model proposes, comprises cable core 1, screen layer 2 and oversheath 3.
Screen layer 2 is coated on the periphery of cable core 1, and oversheath 3 is coated on the periphery of screen layer 2. Screen layer 2 is formed by tinned copper wire braiding, and the count of tinned copper wire is greater than 95%. So, can improve the interference of doing of cable by screen layer 2 being set in the periphery of cable core 1, and tinned copper wire is comparatively soft, is convenient to bending.
Cable core 1 comprises that two cores 11, the first separation layer 12 and two Halogen polyester core body 13, the first separation layers 12 are coated on the cable core body periphery of core 11 and the 13 mutual stranded formation of Halogen polyester core body. The first separation layer 12 is made up of Halogen polyester material. This Halogen polyester material is banded, and the first separation layer 12 is by wrapped the forming of described banded Halogen polyester material. In Halogen polyester material, do not comprise halogen, being subject to flame when barbecue, can not produce the materials such as hydrogen halides, there is low cigarette, fire-retardant effect.
As shown in Figure 2, Fig. 2 is the structural representation of the disclosed core of a kind of fire-resistant shield type motor-car control cables that the utility model proposes. Core 11 comprises conductor 111, insulating barrier 112, the flame retardant coating 113 of being made up of ceramic silicon rubber and the second separation layer 114 of being made up of Halogen polyester. Conductor 111 is made up of five class tinned copper conductors. This conductor 111 by many five class tinned copper wires through regular stranded formation. Five class tinned copper conductors have good electric conductivity, by regular stranded, can improve the pliability of conductor, make cable be convenient to bending, make it be applicable to the cable trench on motor-car. The cross section of Halogen polyester core body 13 is circular, when concrete enforcement, the cross section of Halogen polyester core body 13 can be also the face being surrounded by three semi arches, the diameter of the first semi arch and cable core 1 equal diameters, the diameter of the second semi arch, the diameter of the 3rd semi arch all equate with the radius of the first semi arch, and the opening direction of three semi arches is identical. So, can improve the circularity of cable periphery, be convenient to extruding of oversheath 3.
Flame retardant coating 113 is coated on the periphery of conductor 111, and the second separation layer 114 is coated on the periphery of flame retardant coating 113, and insulating barrier 112 is coated on the periphery of the second separation layer 114. Flame retardant coating 113 is formed by the wrapped periphery at conductor 111 of banded ceramic silicon rubber, and the second separation layer 114 is formed by the wrapped periphery at flame retardant coating 113 of banded Halogen polyester, and banded ceramic silicon rubber is contrary with the lapping direction of banded Halogen polyester. By flame retardant coating is set, can improve the refractory temperature of cable, because ceramic silicon rubber has higher refractory temperature, therefore can demonstrate,prove the in the situation that of flame combustion, cable also can keep the electric property safe operation of 90 minutes below 400 DEG C, for staff's safe escape provides effective time, security performance is good.
