Abstract
The invention discloses a novel watertight cable, comprising a cable core which is obtained through intertwisting three insulation wire cores; a sheath layer is extruded on the outside of the cable core; a first EVA rubber tape laps the outside of the inner sheath in a manner of butt seam lapping; a metal weaving layer is woven on the outside of the first EVA rubber tape; a second EVA rubber tape laps the outside of the metal weaving layer in a manner of butt seam lapping; an outer protective layer is extruded from the outside of the second EVA rubber tape; and the insulation core consists of a conductor, a hot melt glue extruded on the outside of the conductor, a ethylene propylene insulation layer extruded on the outside of the holt melt glue, and a polychloroprene glue layer coated on the outside of the ethylene propylene insulation layer. The novel watertight cable is extraordinary in watertight effect between cable cores and between the cable core layers, and is easy to produce. The increase in the quantity of the cable core and the cross section does not affect the advantage of the watertight performance.
Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of novel watertight cable.
Background technology
Watertight cable is applied in deep sea equipment, along with equipment becomes increasingly complex, being used in such cable in deep sea equipment except needs reaches direction waterproof function, need cable to have function of shielding simultaneously, in order to this two requirements can be reached, the mode of current employing has layer of metal screen at the cable core outer braid of cable, in order to ensure that metal screen layer also has watertightness performance, mainly adopt in two ways: 1, adopt the mode of spreading glue, namely certain thickness butyl glue is had at metal screen layer external application, after butyl glue dries in the shade naturally, carry out extruding oversheath, because oversheath is butyl material, can be good at combining with butyl glue thus playing the water-tight function of metal screen layer, 2, outside metal screen layer, be extruded with one deck EVA rubber mass, be filled in the middle of metal screen layer, thus realize watertightness performance.。
Prior art Problems existing and shortcoming:
Adopt above-mentioned first kind of way, mainly contain the problem of following two aspects: 1, glue can adhesion, but cable is in the process of the test of longitudinal hydraulic pressure, this kind of mode can not bear the test of 7Mpa longitudinal pressure, and its watertightness performance is not good; 2 and need spreading glue in production process, could close after glue to dry in the shade, therefore cable is slow in speed of production.
The main problem of the above-mentioned second way is adopted to be that the EVA rubber owing to extruding is very thin one deck, therefore extrude in process at cable and be difficult to the accurate control cables degree of eccentricity, be easy to occur that some areas metal screen layer occurs leaking the phenomenon of squeezing, and adopt in this way, EVA rubber cannot well stick in metallic shield, therefore, the non-constant of the watertightness performance of whole cable.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of novel watertight cable, has between core, and between core layer, water seal is given prominence to, and convenient production, the increase of cable core radical and cross section does not affect the advantage of watertightness performance.
The novel watertight cable of one of the present invention, comprises cable core, described forms by three insulated wire cores are stranded; Inner sheath is extruded outside cable core, at the wrapped EVA rubber strip of mode that inner sheath adopts opposite joint wrapped outward, at the outer braided metal braid of an EVA rubber strip, again at the wrapped 2nd EVA rubber strip of mode that wire sheathing adopts opposite joint wrapped, finally outside the 2nd EVA rubber strip, extrude outer jacket outward; Described insulated wire cores by conductor, the PUR be extruded in outside conductor, be extruded in second third insulating barrier outside PUR and the neoprene water layer be coated in outside second third insulating barrier is formed.
Further improvement, a described EVA rubber strip is identical with the thickness of the 2nd EVA rubber strip, is 0.1mm.Compared with prior art, beneficial effect of the present invention is:
The problem of what 1, cable of the present invention mainly solved is metallic shield weak effect, in order to solve this technological difficulties, metallic shielding structure of the present invention is " EVA rubber layer+metal screen layer+the two EVA rubber layer ", rubber layer forms by EVA rubber strip is wrapped, the thickness of EVA rubber strip is 0.1mm, bottom pour ladle part can not be had time wrapped, such one side ensures that the outside diameter of cable can not increase, ensure that cable has air when producing and enters metal screen layer on the other hand, thus improve the watertightness performance of cable.
2, two-layer EVA rubber strip is in metallic shield both sides, when extruding oversheath, the rubber of EVA rubber layer melts by the impact of HTHP in continuous vulcanization tube, elastomeric material after thawing can enter the gap of metal screen layer, then the EVA rubber layer meeting sulfuration when HTHP, rubber after sulfuration can be expanded by volume, thus all spaces in the middle of inner sheath and oversheath are filled up, simultaneously EVA rubber can with cable inner sheath and oversheath adhesion tightly, and then improve watertightness performance.
3, the present invention has between core, and between core layer, water seal is given prominence to, and convenient production, the increase of cable core radical and cross section does not affect the advantage of watertightness performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The novel watertight cable of one as shown in Figure 1, comprises cable core, described forms by three insulated wire cores are stranded; Inner sheath 5 is extruded outside cable core, at the outer wrapped EVA rubber strip 6 of mode adopting opposite joint wrapped of inner sheath 5, at the outer braided metal braid 7 of an EVA rubber strip 6, again at the outer wrapped 2nd EVA rubber strip 8 of mode adopting opposite joint wrapped of wire sheathing 7, finally outside the 2nd EVA rubber strip 8, extrude outer jacket 9; Described insulated wire cores by conductor 1, the PUR 2 be extruded in outside conductor 1, be extruded in second third insulating barrier 3 outside PUR 2 and the neoprene water layer 4 be coated in outside second third insulating barrier 3 is formed.
In order to make the performance of cable be optimized further, a described EVA rubber strip 6 is identical with the thickness of the 2nd EVA rubber strip 8, is 0.1mm, makes the overall rounding property of cable better, thus greatly improves the performance of cable.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
