Technical Field

The utility model relates to a wire and cable technical field specifically is a flexible tensile charging cable.

Background

When the cable for the charging system is used, the cable frequently moves like an oil gun, the phenomena of artificial bending, distortion, dragging and even stretching can occur, and the mechanical damage to the charging cable is easily caused; meanwhile, most charging stations are constructed in a matched manner with gas stations, so that the charging stations are at the risk of failure after being polluted by oil. Therefore, the charging cable is required to have higher flexibility, mechanical properties, oil resistance, corrosion resistance, and the like.

However, these cables require frequent movement and drag, which can cause the cables to pull and bend, resulting in easy damage to the cables.

The further technical scheme of the utility model do, the sinle silk is formed by tinned wire and stainless steel wire transposition.

The utility model discloses a further technical scheme does, the insulating layer is the netted layer that the copper wire was woven and is formed.

In order to make the utility model discloses have the effect that tensile strength is good, the utility model discloses a further technical scheme does, the dacron reinforcing rope is two, two the dacron reinforcing rope symmetry sets up the inside at the overcoat.

The utility model discloses a further technical scheme does, the material of inner sheath and oversheath is polyurethane elastomer material.

The further technical scheme of the utility model is that, the insulating layer is the EPT rubber structure.

The further technical proposal of the utility model is that the filling material is silica gel or rubber.

The utility model has the advantages that:

1. the utility model discloses during the use, because the inner core is the curve setting in the overcoat, consequently when dragging the cable, the inner core is the trend of being straightened to avoid the inner core to receive great power of dragging, thereby avoid the inner core to damage.

2. The utility model discloses during the use, add the dacron and strengthen the rope, further increase the whole tensile strength of cable.

In the figure: 1. a wire core; 2. an inner core; 3. a polyester reinforcing rope; 4. an outer sheath; 5. a filler; 11. an insulating layer; 12. a protective layer; 13. a shielding layer; 21. a non-woven fabric belting layer; 22. an inner sheath.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1-2, a flexible tensile charging cable comprises an outer sheath 4 and at least three wire cores 1, wherein the wire cores 1 are wrapped with an insulating layer 11, a protective layer 12 and a shielding layer 13 from inside to outside, all the wire cores 1 are twisted together to form an inner core 2, the inner core 2 is wrapped with a non-woven fabric wrapping layer 21 and an inner sheath 22 from inside to outside, the inner core 2 is arranged inside the outer sheath 4 in a curve shape, a filling material 5 is filled between the inner sheath 22 and the outer sheath 4, and a polyester reinforcing rope 3 is arranged in the outer sheath 4.

In this embodiment, because inner core 2 is the curve setting in overcoat 4, consequently when dragging the cable, inner core 2 is the trend of being straightened to avoid inner core 2 to receive great power of dragging, thereby avoid inner core 2 to damage, set up the whole tensile strength that can greatly increased cable like this, and add dacron reinforcing rope 3 in overcoat 4, further increase the whole tensile strength of cable.

Specifically, sinle silk 1 is formed by tinned wire and stainless steel wire transposition, increases sinle silk 1's tensile strength.

Further, the insulating layer 11 is a mesh layer woven by copper wires.

Preferably, the number of the terylene reinforcing ropes 3 is two, and the two terylene reinforcing ropes 3 are symmetrically arranged inside the outer sheath 4.
