Abstract

The utility model discloses a buoyant cable, which is characterized in that a conductor is made of a tin annealed copper wire, an insulating layer which takes a thermoplastic elastomer as a material is extruded on the conductor to form an insulating wire core; multiple insulating wire cores are stranded to form a cable core; a reinforced layer braid by aramid yarns, an inner sheath layer formed by extruding physical foaming polyurethane (TPU) elastic body materials and an outer sheath layer which takes polyvinyl plastics as materials are sequentially arranged on the cable core from interior to exterior. The buoyant cable has the function of transmitting electric energy and information, has the advantages of small weight, drag resistance, convenience in retracting, high flexibility and long service life, and is suitable for electric appliance connecting lines requiring the cables to float on the water surface for operation.

Description

A kind of buoyant cable

Technical field

The utility model relates to a kind of electrical equipment control cables, relates in particular to a kind of buoyant cable.

Background technology

Buoyant cable is the critical function element of realizing transmitting between the equipments such as naval vessel, water surface robot and the water surface or the underwater operation parts dynamic power, control, and it is related to the realization of electricity consumption equipment function and safety guarantee in naval vessel body and the water surface or the water.

All use common water repellent electric cable as transferring electric power and signal controlling connecting line on the most water surface in the equipment of operation, but because its weight ratio is heavier, all sink at any time the bottom during use, very easily swipe with immersed body in actual use, cause cable fault, thereby reduced the useful life of cable.On the other hand, resistance is also large during retractable cable, also occurs to beat easily to turn round and twine, and has greatly affected the efficient of operation.In order to guarantee that cable has desirable electric property, mechanical and physical performance, is suitable for the characteristic of the specific (special) requirements of floating on water, need to carry out necessary optimization to the existing cable structural design, could satisfy the requirement in its field.

Summary of the invention

The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of buoyant cable is provided, when it has the function of electric energy transmitting and information, also should have lightweightly, anti-pull, folding and unfolding is convenient, the premium properties that good and life-span of pliability is long swims in the electrical appliance connecting wire of operation on the water surface to be suitable for the requirement cable.

The utility model technical solution problem adopts following technical scheme:

The design feature of the utility model buoyant cable is: conductor adopts tin annealed copper wire, and the insulating barrier that extrudes take thermoplastic elastomer (TPE) TPE as material at described conductor consists of insulated wire cores; Consist of cable conductor by a plurality of insulated wire cores twisted synthesizing cables; On described cable conductor, set gradually from inside to outside reinforced layer that aramid fiber yarn is woven into, extrude inner restrictive coating and the external sheath layer take vinyon as material that physical blowing type polyurethane TPU elastomeric material forms.

The design feature of the utility model buoyant cable also is:

Described conductor adopts the 5th class or the 6th class tin annealed copper wire conductor in the GB/T 3956-2008 standard.

Described insulating barrier adopts density to be not more than 0.96g/cm ³The thermoplastic elastomer (TPE) insulating material extrude and form.

The foam degrees of described inner restrictive coating is controlled among the 65-75.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, conductor adopts many tin annealed copper wire lay configuration in the utility model, and bending radius is little, has improved the flexibility of cable; Tin annealed copper wire can prevent effectively that the easy oxidation of bare copper wire from making the resistance increase of cable joint place cause loose contact;

2, the insulating barrier in the utility model has adopted the thermoplastic elastomer (TPE) material, and intensity and specific insulation are higher, good insulation preformance, cold resistance are good, and density is little, lightweight;

3, the utility model whole cable density can float on the water surface less than 1, is convenient to safeguard and folding and unfolding; Have simultaneously good softness, higher mechanical strength can satisfy the requirement of frequent crooked unlikely damage.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 conductor, 2 insulating barriers, 3 reinforced layers, 4 inner restrictive coatings, 5 external sheath layers.

Embodiment

Referring to Fig. 1, the version of buoyant cable is in the present embodiment: conductor 1 adopts tin annealed copper wire, and the insulating barrier 2 that extrudes take thermoplastic elastomer (TPE) TPE as material at conductor 1 consists of insulated wire cores; Consist of cable conductor by a plurality of insulated wire cores twisted synthesizing cables; On cable conductor, set gradually from inside to outside reinforced layer 3 that aramid fiber yarn is woven into, extrude inner restrictive coating 4 and the external sheath layer take vinyon as material 5 that physical blowing type polyurethane TPU elastomeric material forms.

In the implementation, conductor 1 adopts the 5th class or the 6th class tin annealed copper wire conductor in the GB/T 3956-2008 standard; Insulating barrier 2 adopts density to be not more than 0.96g/cm ³The thermoplastic elastomer (TPE) insulating material extrude and form; The foam degrees of inner restrictive coating 4 is controlled among the 65-75.
