Waterproof tensile comprehensive protection layer cable

Technical Field

The utility model relates to a waterproof tensile comprehensive sheath cable, and mainly relates to the field of cables.

Background

The waterproof and tensile comprehensive protection layer cable has higher tensile requirements, the common cable generally utilizes an inner conductor to provide a tensile part, the protection layer outside the cable does not have a tensile effect, the tensile effect is limited, the cable core of the comprehensive cable is generally more, the cable core is easy to displace with the outer protection layer when the cable is pulled and bent, and the problem that the conductor and the protection layer cannot be effectively aligned when the cable core is cut off exists.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the waterproof and tensile comprehensive protection layer cable, which is characterized in that on one hand, a larger section formed by positioning protrusions is utilized, a reinforcing rope is arranged in the section, the space utilization rate of the cable is improved, the diameter of the cable is controlled to be smaller, and on the other hand, the overall tensile strength of the cable can be remarkably improved.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: comprises a cable core and an outer protection structure wrapped on the periphery of the cable core;

the cable comprises at least two cable cores, wherein the outer protective structure is internally provided with positioning protrusions corresponding to the outer gaps of the cable cores, and reinforcing ropes are arranged in the positioning protrusions.

The technical principle and the beneficial effects of the utility model are as follows:

the outside formation clearance between the cable core is necessarily set up to many cable cores, to this, the inner wall of outer sheath sets up the location arch with the cable core interval each other, avoid the cable core to move at will in inside, simultaneously can improve the complex contact surface between cable core and the outer sheath, improve frictional force, so that when cable torsion bending, avoid cable core and outer sheath to have great displacement, utilize the great cross-section that the location arch formed simultaneously on the one hand, strengthen the rope and put in this cross-section, improve the space utilization of cable, make in the diameter control of cable less size, on the one hand can show its holistic tensile strength of improvement.

Preferably, the reinforcing ropes are uniformly distributed with knots. The cable displacement of the reinforcing rope relative to the reinforcing rope can be further avoided by arranging the rope knot.

Preferably, the cable core comprises a conductor, an insulating layer, an inner shielding layer and an inner sheath from inside to outside. The use of an inner shielding layer can avoid the conductors interfering with each other.

Preferably, the insulating layer is made of polyvinyl chloride. Can play a very good insulating effect.

Preferably, the inner shielding layer adopts a tinned copper wire mesh. On the one hand, the anti-corrosion and on the other hand, the shielding effect can be very good.

Preferably, the inner sheath is cross-linked polyethylene. Has better protection effect.

Preferably, the outer protection structure comprises an inner protection layer, a water-resistant layer and an outer protection layer, and the positioning protrusions are arranged on the inner wall of the inner protection layer. The inner protective layer and the outer protective layer are utilized to play roles in protection and water isolation, and meanwhile, the water-blocking layer can absorb water and prevent water from further spreading when water enters.

Preferably, the inner sheath is made of thermoplastic resin. Has better protection effect and wear resistance.

Preferably, the water-blocking layer is water-blocking non-woven fabric. The further spreading of water can be well avoided.

Preferably, the outer protective layer is made of polyethylene. Has excellent wear resistance.
