Abstract

The invention discloses a new energy resource electric car waterproof shield cable. The new energy resource electric car waterproof shield cable comprises two insulated wire cores in the same structure which is a double plying structure, wherein each insulated wire core is formed by a conductor located at the center, and a fireproof low smoke zero halogen irradiation cross linking polyethylene insulation layer, a metal bag tape, a metal net, a fireproof belt and a fireproof low smoke zero halogen irradiation cross linking polyethylene middle quilt, which sequentially wrap the exterior of the conductor in pressing mode, a doubling connection body sleeves the two insulated wire cores, and a thin transparent nylon protecting bush is arranged on the exterior of the doubling connection body. The new energy resource electric car waterproof shield cable has the high performances of preventing water, resisting abrasion, resisting weather, resisting heat, resisting cold, resisting hydrolysis and the like, is suitable for power connection of an electric car charging pile, and can be used as wires used for low voltage cables under severe environment.

Description

A kind of New-energy electric vehicle waterproof shielding cable

Technical field

The invention belongs to power cable field, be specifically related to a kind of New-energy electric vehicle waterproof shielding cable.

Background technology

At present New-energy electric vehicle charging cable structure can be divided into as shown in Figure 1, Figure 2, several structures described in Fig. 3.The construction of cable is as shown in Figure 1 conductor peripheral hardware one deck IXPE insulating barrier 2, insulating barrier 2 peripheral hardware one deck screens 9, screen 9 peripheral hardware one deck IXPE are outer by 10, and this structural disadvantages is not set up defences water-bound, therefore environment for use can only be under drying condition; The construction of cable is as described in Figure 2 in screen 9 and insulating barrier 2, to have increased metal band 3 in the structure of the cable described in Fig. 1, and its defect is identical with Fig. 1 structure; The construction of cable as described in Figure 3 on the basis of Fig. 2 at screen 9 and increased outer band 11 between by 10 outward, between screen 9 and insulating barrier 2, increased interior band 12, outsourcing band material is without clearly stipulating, in Fig. 3, ethylene propylene diene rubber is used in insulation, and the outer polyurethane that is used, because pure macromolecule polyurethane belongs to a small amount of water suction material, can be considered material water-proof material, but pure macromolecule polyurethane is fire proofing not, and ignition temperature is very low, for a long time under high temperature wet condition, easily there is hydrolysising aging phenomenon in polyurethane material simultaneously.

In prior art, cable is single line, and because charging electric vehicle power supply is direct current, DC power supply is divided into positive pole, negative pole, while using single line conductor cable in prior art, need integrate rear use to single line, and it is not convenient to use.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of New-energy electric vehicle waterproof shielding cable that has good waterproof performance, wear-resisting, weather-proof, heat-resisting, cold-resistant, hydrolysis function is provided.

A kind of New-energy electric vehicle waterproof shielding cable of the present invention, this cable comprises the insulated wire cores that two root architectures are identical, and employing is two and line structures, its insulated wire cores, by being positioned at the conductor of center and being extruded in successively fire prevention low smoke and zero halogen IXPE insulating barrier, metal band, wire netting, the fire guard outside conductor, is configured in fire guard, fire prevention low smoke and zero halogen IXPE; Two insulated wire cores overcoats have doubling disjunctor, and doubling disjunctor is provided with the slim transparent nylon sheath of one deck outward.

Further improve, described metal band is clad aluminum foil.

The present invention adopts two insulated wire cores homogeneous textures, and both positive and negative polarity wire is connected by conjoined structure, has improved the actual serviceability of cable installation process.

Beneficial effect of the present invention is:

Compared with prior art, the present invention adopts described insulation and middlely by material, is flame-retardant low-smoke halogen-free material, and temperature resistant grade is 125 ℃ or 150 ℃ of levels, inside establishes fire guard, even if cable, in naked light, can not cause the deformation fracture of cable built-in electrical insulation part in the short time; Peripheral hardware sheath of the present invention is nylon, utilizes the superior function of nylon material, and nylon is commonly called as fiber, has waterproof, wear-resisting, weather-proof, easy cleaning, high strength, thermal endurance, cold resistance, fusing point advantages of higher, thus make cable have the superior functions such as waterproof, wear-resisting, weather-proof, heat-resisting, cold-resistant, hydrolysis; Because direct current is used in New-energy electric vehicle charging, the present invention adopts two insulated wire cores homogeneous textures, and both positive and negative polarity wire is connected by conjoined structure, has improved the actual serviceability of cable installation process.

Embodiment

As shown in Figure 4, a kind of New-energy electric vehicle waterproof shielding cable of the present invention, this cable comprises the insulated wire cores that two root architectures are identical, two insulated wire cores adopt homogeneous texture, its insulated wire cores is by being positioned at the conductor 1 of center and being extruded in successively fire prevention low smoke and zero halogen IXPE insulating barrier 2, metal band 3, wire netting 4, the fire guard 5 outside conductor 1, in fire guard 5, fire prevention low smoke and zero halogen IXPE by 6 formations; Two insulated wire cores overcoats have doubling disjunctor 7, the outer slim transparent nylon sheath 8 of one deck that is provided with of doubling disjunctor 7.

Described metal band 3 is clad aluminum foil.

Principle of the present invention is:

1, the present invention adopts described insulation and middlely by material, is flame-retardant low-smoke halogen-free material, and temperature resistant grade is 125 ℃ or 150 ℃ of levels, inside establishes fire guard, even if cable, in naked light, can not cause the deformation fracture of cable built-in electrical insulation part in the short time;

2, peripheral hardware sheath of the present invention is nylon, utilize the superior function of nylon material, nylon is commonly called as fiber, there is waterproof, wear-resisting, weather-proof, easy cleaning, high strength, thermal endurance, cold resistance, fusing point advantages of higher, from but cable has the superior functions such as waterproof, wear-resisting, weather-proof, heat-resisting, cold-resistant, hydrolysis;

3, because direct current is used in New-energy electric vehicle charging, the present invention adopts two insulated wire cores homogeneous textures, and both positive and negative polarity wire is connected by conjoined structure, has improved the actual serviceability of cable installation process.
