Description

A kind of direction waterproof degaussing cable

Technical field

The utility model relates to joins field of cable technology, particularly relates to a kind of direction waterproof degaussing cable.

Background technology

What its insulation of the watertight degaussing cable of current domestic institute production and application and sheath material adopted is elastomeric material, in order to the conductor that the mode making cable have good watertightness performance employing is at water shape cipher telegram cable, conductor and insulation junction, insulated wire cores gap, cable core and sheath junction are coated with neoprene glue.Extruded insulation, to extrude in sheath operation can cable can sulfuration in curing tube, after sulfuration neoprene glue can and the junction of rubber produce the articulamentum of densification, thus achieve cable watertightness performance.

And the insulation that external produced watertight degaussing cable uses and sheath material mostly are plastics, at the conductor of cable, conductor and insulation junction, insulated wire cores gap, cable core is connected gel glue with sheath, adopt and not only make the external diameter of cable reduce in this way, and be that weight also alleviates relatively, and watertightness is remarkably productive.

Prior art Problems existing and shortcoming:

Adopt domestic method, the water seal of cable is bad, and at the trial, one end of cable is immersed in the water, and the pressure 7Mpa added, the other end exposes in atmosphere, and test 24 hours, the center of conductor has water droplet and goes out.Main cause is that the glue of cable inside can adhesion good with rubber, but just very poor for the adhesion performance of glue and conductor.

Utility model content

The utility model, in order to solve the problem of prior art, provides a kind of softness good, the direction waterproof degaussing cable lightweight, water seal is good.

A kind of direction waterproof degaussing cable described in the utility model, comprises cable core, and described cable core forms by three insulated wire cores are stranded side by side; Its insulated wire cores is made up of conductor layer and the insulating barrier be extruded in outside conductor layer; The EVA rubber strip that the thickness be made up of EVA rubber is 3mm is filled in the gap of cable core; Oversheath is extruded outside cable core; The center stranded side by side three insulated wire cores is provided with arc limit triangular support sheath, and three limits of its arc limit triangular support sheath are closely harmonious with the arc limit of three insulated wire cores respectively.

Further improvement, described conductor layer forms by adopting the conductor of 1+6 structure and EVA rubber strip to carry out multiple strand simultaneously, makes that the structure of conductor layer is more stable, watertightness is better.

Further improvement, described conductor carries out bundle strand by the zinc-plated flexible conductor monofilament and EVA rubber strip that adopt 1+6 structure simultaneously and forms, and makes that the structure of conductor is more stable, watertightness is better.

Compared with prior art, the utility model beneficial effect is: the utility model center is provided with triangular support sheath and EVA rubber strip is filled in gap, and make three insulated wire cores structure in cable core more stable, can not be subjected to displacement, watertightness is better; Conductor layer by conductor according to 1+6+12+6(n-1) structure of (n is the number of plies, n > 1) carries out multiple strand and forms, and makes that the structure of conductor layer is more stable, watertightness is better; Conductor is again by employing 1+6+12+6(n-1) (n is the number of plies, n > 1) the zinc-plated flexible conductor monofilament of structure and EVA rubber strip carry out bundle strand simultaneously and form, make that the structure of conductor is more stable, watertightness is better, above structure makes the structure of Integral cable more firm, is not easily subjected to displacement.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

A kind of direction waterproof degaussing cable as shown in Figure 1, comprises cable core, and described cable core forms by three insulated wire cores are stranded side by side; Its insulated wire cores is made up of conductor layer 1 and the insulating barrier 2 be extruded in outside conductor layer 1; The EVA rubber strip 3 that the thickness be made up of EVA rubber is 3mm is filled in the gap of cable core; Oversheath 4 is extruded outside cable core; The center stranded side by side three insulated wire cores is provided with arc limit triangular support sheath 5, and three limits of its arc limit triangular support sheath 5 are closely harmonious with the arc limit of three insulated wire cores respectively; Wherein, described conductor layer forms by adopting the conductor 6 of 1+6 structure and EVA rubber strip 3 to carry out multiple strand simultaneously, makes that the structure of conductor layer is more stable, watertightness is better; Described conductor 6 carries out bundle strand by the zinc-plated flexible conductor monofilament 7 and EVA rubber strip 3 that adopt 1+6 structure simultaneously and forms, and makes that the structure of conductor is stablized more, watertightness is better.

Operation principle of the present utility model or the course of work:

Main preparation methods of the present utility model be in the middle of cable conductor, conductor and insulation Contact, the junction of insulating inner gap, cable core and sheath is all filled with EVA rubber strip, EVA rubber filling mode is that EVA rubber is made the band shape that glue thickness is 3mm, then EVA rubber is heated, its temperature is between 65 DEG C to 70 DEG C, and now EVA rubber becomes a kind of form of glue, in bundle strand, multiple strand, cabling process, by the instillation of EVA rubber wherein, stranded together.Cable needs to carry out sulfuration in the process extruded, and in sulfidation, EVA rubber and insulation, sheath is connected together, and makes cable become as a whole to insulation to restrictive coating from conductor, and not peelable.By test, one end of cable is immersed in the water, and the 7Mpa that pressurizes, the other end exposes in atmosphere, and test 24 hours, the anhydrous precipitation of cable, cable cover(ing) and insulation position are not subjected to displacement.

The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
