Abstract

The utility model discloses a towing-resistance flexible cable. The cable comprises three groups of cable cores. A center of each cable core is provided with a tinned copper conductor. An isolation strip, an ethylene propylene rubber insulation layer and a first hair cord braiding layer successively wrap the tinned soft copper conductor. The three groups of cable cores are arranged in an inner sheath. A second hair cord braiding layer and an outer sheath successively wrap the inner sheath. Compared to the prior art, by using the flexible cable of the utility model, on one hand, the hair cord is used to carry out high-density braiding outside the core insulation; on the other hand, the hair cord is used to carry out sparse braiding outside the inner sheath; then the outer sheath is extruded so that the outer sheath, the braiding layers and the inner sheath are integrated and a tensile ability is greatly increased.

Description

The anti-flexible cable that drags

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 usually uses about half a year various breakage failures namely 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, between each insulated wire cores in cable core, all easily produce gap, 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

In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.

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, in described three groups of cable cores, 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.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 namely limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as with the utility model specification and graphic content, doing, all should be contained in the scope of the claims of the present utility model.
