Abstract
The utility model discloses an underwater acoustic transducer special cable which comprises a plurality of conductors which are respectively wrapped by an ethylene propylene rubber insulating layer to form insulated wire cores, and the insulated wire cores are twisted into a bundle to form a cable core which is extruded by ethylene propylene rubber to be a compact filling and an inner sheath to form an integral outer insulation layer. The outer insulation layer is externally provided with a signal shielding layer, an isolation layer formed by the winding of a polyester belt, and a chlorosulfonated polyethylene rubber outer sheath layer. The underwater acoustic transducer special cable has simple and reasonable structural design, the ethylene propylene rubber extrusion is employed by the outer insulation layer such that the filling and the inner sheath form a compact whole body, thus the insulation performance and the waterproof performance of the cable are good, the waterproof chlorosulfonated polyethylene rubber is employed by the outer sheath for extrusion molding, and the cable has the functions of inflaming retarding, softness, abrasion resistant and impermeability of two ends of the cable under 6.5Mpa water pressure.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of underwater acoustic transducer private cable.
Background technology:
It is that sonar is found range that surface ship, underwater submarine and large-scale foreign-going ship all will load underwater acoustic transducer, to distinguish naval vessels or the submarine distance of other objects on every side.Because the particularity of environment for use, the cable that requires to connect between power supply and the underwater acoustic transducer has the specific (special) requirements that is different from other cable, as cable require soft, wear-resisting and under 6.5Mpa hydraulic pressure the cable two ends do not seep water etc., traditional rubber insulation and sheath soft cable can not meet the demands fully.
Therefore need to redesign the construction of cable, select the insulation of ethylene-propylene rubber mixture do, chlorosulfonated polyethylene rubber mixture to make sheath, and the chlorosulfonated polyethylene sheath formula of rubber studied, develop the special-purpose chlorosulfonated polyethylene sheath rubber flexible cable (sonar cable) of underwater acoustic transducer.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of underwater acoustic transducer private cable, reasonable in design, good insulation preformance, soft, wear-resisting and under 6.5Mpa hydraulic pressure the cable two ends do not seep water.
The technical solution of the utility model is as follows:
The underwater acoustic transducer private cable, comprise several conductors, it is characterized in that: described several conductors are enclosed with respectively the ethylene-propylene rubber insulated layer outward and consist of insulated wire cores, the mutual stranded bunchy of insulated wire cores consists of cable core, cable core is provided with ethylene-propylene rubber outward and is extruded into closely knit filling and becomes as a whole external insulation layer with inner sheath, and described external insulation layer is provided with separator, the chlorosulfonated polyethylene rubber external sheath layer of signal shielding layer, the wrapped formation of polyester belt outward successively.
Described underwater acoustic transducer private cable is characterized in that: described several conductors adopt 5 classes or 6 class tinned copper conductors.
The utility model has the advantages that:
The utility model structural design advantages of simple, external insulation layer employing ethylene-propylene rubber is extruded and is made filling become a closely knit integral body with inner sheath, so that insulating performance of cable and water resistance are good, oversheath adopts the chlorosulfonated polyethylene rubber extrusion molding of waterproof, makes cable have fire-retardant, soft, wear-resisting and the impermeable function in cable two ends under 6.5Mpa hydraulic pressure.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
The underwater acoustic transducer private cable, comprise several conductors 1, several conductor 1 outer ethylene-propylene rubber insulated layers 2 that are enclosed with respectively consist of insulated wire cores, the stranded bunchy of insulated wire cores consists of cable core, do not fill, not wrapped, cable core adopt outward ethylene-propylene rubber extrude into closely knit external insulation layer 3(fill become as a whole with inner restrictive coating), external insulation layer 3 is provided with separator 5, the chlorosulfonated polyethylene rubber external sheath layers 6 of signal shielding layer 4, the wrapped formation of polyester belt outward successively.
Filling outside cable core is the closely knit external insulation layer 3 that extrudes into an integral body with inner sheath, not only plays waterproof but also play shielding insulation.
At the external insulation layer 3 outer signal shielding layers 4 that arrange, make cable when signal transmission, avoid external interference.
The utility model laying up pitch little (10 times of external diameters); Cable rounding and closely knit can vertically not seep water;
The signal shielding layer 4 of tinned copper wire braiding prevents that effectively extraneous signal is to the interference to external instrument of the interference of cable and cable signal; At the signal shielding layer 4 outer separator 5 that arranges to prevent the adhesion between external sheath layer 6 and the signal shielding layer 4.
