Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Of the present utility model this skeletal support formula multi-core controlled cable as shown in Figures 1 to 3; this control cables is applicable to the system such as industrial frequency AC rated voltage 0.45/0.75kV and following automatic control, monitoring circuit, protection circuit, and the indoor, cable trough, pipeline, direct-burried etc. of be fixedly the laid in industries such as metallurgy, electric power, building require fire-retardant, fire-resistant and can bear the occasion of larger mechanical external force.It comprises oversheath 10, metal armor layers 20, band 30, packed layer 40, skeleton 50 and multiple conductor element 60.Described oversheath 10 is wrapped in outside described band 30, and described metal armor layers 20 is between described band 30 and oversheath 10, and described skeleton 50 is positioned at described band 30, and described packed layer 40 is positioned at described skeleton 50.The external diameter of described oversheath 10 is 23.5mm, and the thickness of this oversheath 10 is 1.7mm, and described oversheath 10 is made up of polyethylene.Band 30 is made up of nonwoven fabrics, and thickness is 1.2mm.The selection of packed layer 40, metal armor layers 20 etc. can refer to prior art, and this place does not repeat.Described conductor element 60 is integrally contained in skeleton 50 as one, and this conductor element 60 at least comprises copper conductor and is coated on the insulating barrier outside this copper conductor.
The external diameter of described skeleton 50 is 17 to 19mm, and skeleton 50 comprises axis 51, multiple spacer portion 52 and stop part 53, and one end of described spacer portion 52 is fixed on described axis 51, and the other end is connected to the middle part of described stop part 53.Stop part 53 is positioned at skeleton 50 outermost, rounded, and circular structure is convenient to wrapped nonwoven fabrics.Adjacent described spacer portion 52 forms a container cavity 54, and described conductor element 60 is positioned at this container cavity 54, and container cavity 54 enriches by packed layer 40.Adjacent described stop part 53 forms a fluting 55, and conductor element 60 can clamp-on container cavity 54 from fluting 55, and the width of this fluting 55 is 1 to 2mm, and the external diameter of this conductor element 60 is 2.7 to 3.5mm.The width of fluting 55 is less than the diameter of conductor element 60, and fluting 55 can hinder conductor element 60 to come off.Without the need to increasing extra component, conductor element 60 is remained in container cavity 54 in installation process, therefore easier for installation.Described skeleton 50 adopts rubber to make, and rubber has certain intensity, and allows to clamp-on deformation.The width of described spacer portion 52 is 0.2 to 0.9mm, and this width range can the certain suppleness of retentive control cable.In addition, in described axis 51, be provided with through hole 56, many group reinforcing fibres 57 are installed in this through hole 56.Reinforcing fibre 57 can improve the resistance to tension of cable, is about 2100N.
As Fig. 2,3, the thickness of described metal armor layers 20 is 3mm, and it comprises the metal tape 21 of more than, and metal tape 21 spiral winding forms tubular structure.Described metal tape 21 comprises trip 22, can hold the draw-in groove 23 of this trip 22 and connects the sliding part 24 of this draw-in groove 23 and trip 22, and the length of described draw-in groove 23 is greater than described trip 22.When metal tape 21 is wrapped in outside band 30, draw-in groove 23 pushes down the trip 22 of below, thus realizes the shaping of whole metal tape 21.Certainly, the mode that many strip metals band 21 adopts many helical pitches to install side by side also can.201110059457.6 disclosed that interlocking metal armoring, comprises the metal tape of snapping successively.But in this case, the scope of the mutual changing of the relative positions of metal tape connecting portion is limited, shows as pliability inadequate.In the utility model, the length of draw-in groove 23 is comparatively large, allows trip 22 to move wherein.The accessible movement of trip 22 improves the pliability of cable.In the utility model, described draw-in groove 23 has an opening 25, and the width of this opening 25 is more than or equal to the width of described sliding part 24.Sliding part 24 is flat surface, allows the end of opening 25 to slide thereon.This structure guarantees that trip 22 is positioned at draw-in groove 23 all the time while the accessible movement of trip 22.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
