Abstract

The utility model relates to a cable, in particular to a sonar watertight cable, the center of the sonar watertight cable is equipped with a padding core, each twisted-pair group is formed by coating an insulating layer outside wire cores, the wire cores coated the insulating layers are twisted into a twisted-pair group, the twisted-pair group is hermetically equipped with a shielding layer, the twisted-pair groups equipped with the shielding layers are arranged along the circumferential direction of the padding core, an inner sheath is mounted outside the twisted-pair group, an outer sheath is mounted outside the inner sheath, and filling materials are filled in a gap between the inner sheath and the shielding layer. The twisted-pair group structure of the utility model arranges guide wires more closely, the inner sheath and the outer sheath are sheaths capable of resisting and proofing water, thereby increasing the watertight performance of the cable, the shielding layer of the cable is a braided shield, thereby guaranteeing the effective transmission performance of the cable, the inner sheath, the outer sheath and an armor layer guarantees normal work of the cable under 350 m water. The sheaths utilize rubber materials, which have water resisting, water proofing and wear resistant performances, thereby meeting use requirements of the cable.

Description

The sonar watertight cable

One, technical field:

The utility model relates to power equipment, particularly cable.

Two, background technology:

Along with the high speed development that China's national defense is built, particularly naval's defence is powerful.Sonar carries out the major technique that undersea surveillance is used as various countries naval, is used for submarine target is surveyed, classifies, located and follows the tracks of; Carry out subsurface communication and navigation, ensure the tactical maneuver of naval vessels, antisubmarine aircraft and anti-submarine helicopter and the use of underwater weapon.In addition, sonar technique also is widely used in torpedo guidance, sea mine fuze, and the exploration of the locating fish, offshore oil drilling, marine navigation, underwater operation, hydrographic survey and seabottom geology landforms etc.

Sonar equipment generally is made up of basic matrix, electronics rack and auxiliary equipment three parts.Basic matrix is arranged in a combination with certain geometric figure by underwater acoustic transducer, and its profile is generally sphere, cylindricality, plate shaped or alignment row, and the branch that receives basic matrix, transmitter battle array or transmitting-receiving unification basic matrix is arranged.Electronics rack generally has subsystems such as emission, reception, demonstration and control.Devices such as auxiliary equipment comprises power-supply device, stube cable, junction box and repeater, the lifting, revolution, pitching, the folding and unfolding that match with the transmission control of sonar transducer array under water, pulls, hangs, input, and sonar dome etc.As its specification requirement height of stube cable that auxiliary equipment is used, manufacture difficulty is big, always dependence on import.

Three, summary of the invention:

The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of sonar watertight cable is provided, have good block water, waterproof, watertightness performance.

The technical scheme that the utility model is adopted for achieving the above object is: the sonar watertight cable, bedding core is equipped with at the center, the pair twist group is a core outsourcing insulating layer coating, the core of coated insulation layer is proofreaded into the pair twist group, screen is equipped with in pair twist group sealing, and the pair twist group that screen is housed take the bedding core as the center circumferential direction pair twist group of arranging, and the pair twist group is equipped with inner sheath outward, inner sheath is equipped with oversheath outward, the filler that the gap location between inner sheath and the screen is filled.

Described inner sheath is equipped with armour outward, and armour is that count is not less than 65% zinc-coated wire braiding, and armour is equipped with oversheath outward.

Described screen is that count is not less than 80% zinc-plated soft copper silk braid.

Described insulating barrier is a polyethylene layer.

Described filler is the good rubber filler of sealing.

Described inner sheath and oversheath are the caulking gum sheath.

The utility model is rational in infrastructure, still there is not the homogeneous structure product at present, its pair twist group structure lead of arranging more closely, and interior oversheath all adopt block water, the sheath of waterproof, improved the watertightness performance of cable, the screen of cable is a braid shielded, has guaranteed effective transmission performance of cable, the braided steel wire armour is housed between the inside and outside sheath, guaranteed cable under water the following cable of 350m radially can operate as normal with transverse pressure effect cable.Sheath adopts performances such as elastomeric material blocks water, waterproof antiwear, satisfies the cable instructions for use.

Fig. 2 is the utility model 72 cored structure schematic diagrames.

Five, embodiment:

Embodiment 1

26 core sonar watertight cables as shown in Figure 1, cable list core is specification 0.34mm ²The tin annealed copper wire that meets national standard, bedding core 4 is equipped with at the center, pair twist group 3 is the conductor wire core 1 outer polyethylene layer 2 that coats, the core of coated insulation layer is proofreaded into the pair twist group, screen 9 is equipped with in the sealing of pair twist group, screen is that count is not less than 80% zinc-plated soft copper silk braid, the pair twist group that screen is housed take the bedding core as the center circumferential direction two layers of pair twist group of arranging, 3 groups of internal layers, outer 10 groups, the pair twist group extrudes outward inner sheath 6 is housed, gap location between inner sheath and the screen is filled with the good rubber filler 5 of sealing, and inner sheath is equipped with armour 7 outward, and armour is that count is not less than 65% zinc-coated wire braiding, armour is equipped with oversheath 8 outward, and inner sheath and oversheath are the caulking gum sheath.

Embodiment 2

Sonar watertight cable as shown in Figure 2, several 72 cores of core, single core specification 0.34mm ², basic structure is identical with embodiment 1, and pair twist group 3 that different is is that center of circle circumferencial direction arranges with bedding core 4 is three layers, and ground floor is 6 groups from inside to outside, 12 groups of the second layers, the 3rd layer 18 groups.
