Abstract
Disclosed in the utility model is a dragging-resistant flexible cable comprising three groups of cable cores. Tin-plated copper conductors are arranged in the centers of the cable cores; isolating belts, ethylene propylene rubber insulation layers, and first ramie yarn braiding layers successive coat the outsides of the tin-plated copper conductors. The three groups of cable cores are arranged in an inner sheath; a second ramie yarn braiding layer and an outer sheath successively coat the outside the inner sheath. Compared with the prior art, on the one hand, ramie yarns arranged outside the cable core insulation are used for high-density braiding; and on the other hand, ramie yarns are also arranged outside the inner sheath for sparse braiding and then outer sheath extruding is carried out. Therefore, the outer sheath, the braiding layers and the inner sheath are integrated into one, thereby substantially enhancing the tensile force.
Description
Technical field
the utility model belongs to the cable technology field, is specifically related to a kind of anti-flexible cable that drags.
Background technology
the sea-freight prosperity develops harbour machinery rapidly, but because harbour machinery lifts frequent, matched cable often need to be done high-speed mobile, bear larger pulling force and bending, traditional flexible cable is usually used about half a year various breakage failures occurs, impact is used, and needs to have novel high-performance towing flexible cable supporting with it for this reason.The fillings such as the glass fibre that the many employings of prior cable are extra or the rope made of hemp, but, no matter adopt which kind of additional materials to fill, all easily produce gap between each insulated wire cores in cable core, especially for " 3 large 1 is little " this common structure flexible cable, all the more so.This just makes in harbour machinery operation occasion cable loading process the distortion that can produce stranded core, and outer field sheath is because of more soft, and core will protrude and cause the cable outward appearance uneven, and physical property and electric property all are subject to very major injury.
The utility model content
the purpose of this utility model is to provide a kind of anti-flexible cable that drags of new construction, and it is wear-resistant tensile not only, and often high-speed mobile is pulled also not cracky, thereby addresses the above problem.
for realizing this purpose, the technical solution of the utility model is: a kind of anti-flexible cable that drags, comprise three groups of cable cores, described cable core center is provided with tinned copper conductor, described zinc-plated soft copper conductor is coated with isolation strip, ethylene propylene rubber insulated layer, the first dimity braid outward successively, in described three groups of cable cores, be located in an inner sheath, described inner sheath is coated with the second dimity braid, oversheath outward successively.
as preferably, described oversheath is chloroprene rubber sheath.
as preferably, described zinc-plated soft copper conductor by many tin-coated copper single cords oppositely multiple strand form.
as preferably, the count of described the second dimity braid is controlled between 60%-75%.
compared with prior art, the utility model considers that in use procedure, cable need bear larger pulling force, and on the one hand online core insulation has adopted the dimity to carry out high density braided outward; Outside inner sheath, also adopt on the other hand the dimity to carry out sparse braiding, and then extrude oversheath, thereby oversheath, braiding and inner sheath are combined together, greatly strengthen resistance to tension.Wherein, extrude inner sheath and adopt squash type to extrude the high-strength anti-flaming neoprene, in order to fix the position of each insulated wire cores and guarantee to tamp the gap between insulated wire cores; Extrude oversheath and adopt the high-strength anti-flaming neoprene, make it infiltrate the gap between braid, and be connected into one with inner sheath, improved the wear-resistant tensile performance.
The accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
wherein: 1. zinc-plated soft copper conductor, 2. isolation strip, 3. insulating barrier, 4. the first dimity braid, 5. inner sheath, 6. the first dimity braid, 7. oversheath.
embodiment
the utility model is further illustrated with reference to the accompanying drawings in conjunction with the embodiments.
as shown in Figure 1, a kind of anti-flexible cable that drags, comprise three groups of cable cores, described cable core center is provided with tinned copper conductor 1, outer isolation strip 2, ethylene propylene rubber insulated layer the 3, first dimity braid 4 of being coated with successively of described zinc-plated soft copper conductor 1, be located in inner sheath 5 outer the second dimity braid 6, the oversheath 7 of being coated with successively of described inner sheath 5 in described three groups of cable cores.Wherein, described oversheath 7 is chloroprene rubber sheath; Described zinc-plated soft copper conductor 1 is oppositely twisted and forms again by many tin-coated copper single cords; The count of described the second dimity braid 6 is controlled between 60%-75%.
the utility model drags mainly for anti-the improvement that soft cable structure carries out, the foregoing is only the utility model preferred embodiment, non-so limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as doing by the utility model specification and graphic content, all should be contained in the scope of the claims of the present utility model.
Claims (4)
1. the anti-flexible cable that drags, comprise three groups of cable cores, it is characterized in that, described cable core center is provided with tinned copper conductor, described zinc-plated soft copper conductor is coated with isolation strip, ethylene propylene rubber insulated layer, the first dimity braid outward successively, in described three groups of cable cores, be located in an inner sheath, described inner sheath is coated with the second dimity braid, oversheath outward successively.
