CN201877196U - Cable for new-energy automobile - Google Patents

Abstract

The utility model discloses a cable for a new-energy automobile, which is characterized in that a plurality of stranded copper conductors are adopted, flexible materials are extruded on the copper conductors so that an insulating layer is formed, a shielding layer made of tinned copper wires by means of weaving is arranged outside the insulating layer, and radiation crosslinking polyolefin is extruded outside the shielding layer and serves a sheath. The cable is high in voltage-resistance, current-carrying capacity and temperature-resistant grade, is resistant to electromagnetic interference, and has the advantages of low smoke, zero halogen, flame resistance and environmental protection.

Description

The new-energy automobile cable

Technical field

The utility model relates to cable, a kind of cable of using as the active force electric power transfer on the new-energy automobiles such as hybrid power, pure electronic or fuel cell of being applied to of more specifically saying so.

Background technology

Existing orthodox car mainly is to be power resources with the fuel oil, and widely used electric wire mainly is that sectional area is at 4mm on this class automobile ²Below, to adopt polyvinyl chloride or polyolefin be insulating material, its version is to adopt naked copper stranded conductor, polyvinyl chloride or polyolefin to extrude insulation.

Along with the development and use of environmental protection and new forms of energy, adopt the new-energy automobile of green environmental protection technique to arise at the historic moment, and widelyd popularize, traditional electric wire has been difficult to satisfy the instructions for use of new-energy automobile, mainly has the following disadvantages:

1, sectional area is little, and is withstand voltage low, can not be high pressure resistant and the big electric current used of carrying active force;

2, operating temperature range is little, and heatproof is low;

3, be easy to generate the magnetic field of interference during bearing great current, the sensitivity of human body and instrument and meter around the harm;

4, contain halogen in the insulating material, be easy to generate a large amount of smog during burning, environmental protection is not required yet.

Summary of the invention

The utility model is for avoiding above-mentioned existing in prior technology weak point, for satisfy new-energy automobile to bearing great current, high pressure resistant, suppress electromagnetic interference, and requirements such as low cigarette, Halogen, fire-retardant, environmental protection provide a kind of new-energy automobile cable

The utility model technical solution problem adopts following technical scheme:

The utility model new-energy automobile is to adopt the copper conductor of strands with the design feature of cable, on described copper conductor, extrude elastomeric material and form insulating barrier, outside at insulating barrier forms screen with the tinned copper wire braiding, extrudes the cross-linking radiation polyolefin as sheath in described screen outside.

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

The withstand voltage height of the utility model, big, the anti-electromagnetic interference of current-carrying, the high and low cigarette of heatproof, Halogen, fire-retardant, environmental protection.

1, to have adopted the stranded mode of multiply bare copper wire to increase its cross-sectional area of conductor long-pending for the utility model, and D.C. resistance is diminished, and the cable current capacity is stronger, and this structure has also guaranteed the pliability of cable simultaneously, is easy to the laying installation of cable.

2, the insulating barrier in the utility model has adopted elastomeric material, makes it have excellent environmental resistance and ageing resistace, and its good electrical properties makes it withstand voltage higher.

3, the shielding construction that increased of the present utility model, shielding density be more than 85%, suppressed the release to surrounding environment of electromagnetic wave that cable produced when transmission high voltage or big electric current effectively.

4, each raw material has all adopted low cigarette, Halogen, fire-retardant, environment-friendly materials in the utility model, and these have satisfied the instructions for use of new-energy automobile to its components and parts.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 conductor, 2 insulation, 3 shieldings, 4 sheaths.

Embodiment

Referring to Fig. 1, adopt the copper conductor 1 of strands in the present embodiment, on copper conductor 1, extrude elastomeric material and do insulating barrier 2, form screen 3 in the outside of insulating barrier 2 with the tinned copper wire braiding, extrude the cross-linking radiation polyolefin as sheath 4 in screen 3 outsides.

In concrete the enforcement, copper wire forms conductor 1 through strands, extrudes elastomeric material as insulating barrier 2 in conductor 1 outside, adopts tinned copper wire woven shield 3, and restrictive coating 4 is extruded in outermost layer, and restrictive coating is through the high-energy electron accelerator cross-linking radiation.

Claims (1)

1. new-energy automobile cable, it is characterized in that adopting the copper conductor (1) of strands, on described copper conductor (1), extrude elastomeric material and form insulating barrier (2), outside at insulating barrier (2) forms screen (3) with the tinned copper wire braiding, extrudes the cross-linking radiation polyolefin as sheath (4) in described screen (3) outside.
