Abstract
The utility model discloses a shielded high flexible cable, which is characterized in that a conductor is composed of fine copper wires which are twisted in a composite bunched and stranded mode, the outer layer of the conductor is sequentially provided with an isolating layer and an insulating layer so as to form an insulated wire core, and a plurality of insulated wire cores are stranded by way of twisting so as to form a cable core; and the outer layer of the cable core is sequentially provided with a belting layer, a metal-wire total shielding layer and an outer sheath layer. The shielded high flexible cable disclosed by the utility model both can guarantee good shielding, and can meet the requirements on softness, therefore, the shielded high flexible cable adapts to various different working environments, and can be used as a connecting wire for mechanical equipment under special conditions.
Description
Technical field
The utility model relates to a kind of flexible cable, relates in particular to a kind of shield type high flexible cable, belongs to technical field of electric wires and cables.
Background technology
In the application scenarios such as the manipulator on sprocket wheel, streamline, multi-function robot, harbour plant, crane, wind turbine generator; Because working particularity; Need to use special cord cable, under particular surroundings, cable also need have shielding properties; It requires the flexible performance good, the time can stand unidirectional for a long time or compound bending in work, and the needs that have stand unidirectional or bidirectional torsion for a long time, also have need be through by bending, the teamwork reversing and stretch.The general design service life of high flexible cable was not less than 5 years, it is estimated, the mechanical action that this cable stood can reach 1,000,000 to 5,000,000 cycles in different use occasions.But Related product of the prior art exists the contradiction that is difficult to overcome on shielding construction and softness.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of and can guarantee good shielding, can satisfying the shield type high flexible cable that softness requires again.
The utility model adopts following technical scheme for the technical solution problem:
The design feature of the utility model shield type high flexible cable is: conductor adopts thin copper wire through a bundle strand and burst compound stranded the forming of strand; Skin at said conductor sets gradually separator and insulating barrier formation insulated wire cores, constitutes cable conductor by the stranded stranding of a plurality of insulated wire cores; Skin at said cable conductor sets gradually belting layer, the total screen of wire and external sheath layer.
The design feature of the utility model shield type high flexible cable also is:
The thin copper wire that constitutes said conductor is that diameter is the tinned copper wire of 0.05-0.10mm, or is silver-gilt copper wire.
Said insulating barrier adopts silicon rubber, vinylacetate rubber or ethylene-propylene rubber;
Said belting layer adopts teflin tape.
The total screen employing of said wire diameter is that tinned copper wire and the nylon yarn mixing of 0.10mm is entwined.
Said external sheath layer is to be extruded by thermoplastic polyurethane elastomer or thermoplastic polyurethane elastomer material to form.
Compared with present technology, the beneficial effect of the utility model is embodied in:
1, the utility model adopts zinc-plated or silver-gilt copper wire, can prevent effectively that copper conductor from increasing the problem of generating heat because of oxidation makes itself and joint resistance; Adopt thinner conductor monofilament to make Cable Bending Radius littler; A conductor bundle strand structurally and a strand strand composite construction make its symmetrical configuration, and cable is stressed even more and stable in BENDING PROCESS.
2, insulating barrier is soft more in the utility model, has good electric property, is prone to processing, meets the requirement of soft type cable.
3, the utility model belting layer adopts teflin tape, and is thinner than extruding inner sheath, and mechanical performance is higher than and extrudes the inner sheath material, guaranteeing to have reduced the physical dimension of cable as much as possible under the prerequisite of quality.
4, mix the total screen that twines formation with zinc-plated thin copper wire and nylon yarn in the utility model, more structurally make cable gentleer, thinner, help strengthening the bending property of cable, prolong its useful life with the braiding copper wire.
5, the utility model in be that material extrudes the external sheath layer that forms and more embodies following excellent properties with thermoplastic polyurethane elastomer or thermoplastic polyurethane elastomer:
A, be not easy to also can as PE, not wear out and stress cracking, cause the electric property of cable and environmental resistance to reduce because of various environmental factor hardening;
B, the same with rubber wear-resisting, soft, characteristics that weather resisteant is good are arranged, but its processing technology is much simpler than rubber, can adds hot-extrudablely, and need not vulcanize as materials such as PVC, PE;
C, under-60 ℃ of low temperature condition, still can keep good bending property, even repeatedly also can not ftracture with very little bend radius;
D, the environmental-protecting performance of material own meet the ROHS of European Union instruction;
E, in atmosphere such as greasy dirt, chemicals, soda acid, also has premium properties;
F, can satisfy requirement in 90 ℃ of ambient temperatures and following long-term work.
