Description

Gear type anti-twisting charging wire for soft new energy automobile

Technical Field

The utility model relates to a cable technical field specifically is an anti charging wire of turning round soft new energy automobile of beating of gear type.

Background

Chinese patent CN106024150B discloses a new energy ac charging gun cable, which includes power transmission lines, signal transmission lines, auxiliary lines, a tissue layer and TPE protective layers, wherein three power transmission lines and one signal transmission line are symmetrically arranged in the center of a circle, two auxiliary lines are symmetrically arranged at two sides of the signal transmission line, the gaps between the power transmission lines, the signal transmission lines and the auxiliary lines are filled with fillers to form core wires, and the tissue layer and the TPE protective layers are sequentially coated on the core wires from inside to outside. The rifle cable that charges of this patent belongs to the solid construction cable, and is the same with current rifle cable that charges, all has following problem:

the new energy charging wire belongs to a non-fixed laying wire, and is frequently moved and twisted in the using process, and the existing wrapping belt wrapping extrusion sheath type charging wire has the defects of twisting, swelling and the like; beat and turn round the outward appearance that the swell not only influenced the charging wire, because beat to turn round the swell and can be accompanied with the kinking deformation of conductor, the wire rod temperature rise can rise relatively during the use, beat the wire rod of turning round the swell and exist the risk of burning the line if long-term use.

New forms of energy charging wire cable core specification variation in size belongs to different core cable, and the cable core structure is unstable, and when the torsion when using was moved, the radial great torsional force that can produce of wire rod, the sheath is not hard up under the effect of radial torsional force, and the easy dislocation of cable core warp, and the wire rod is beaten and is turned round the swell. The existing common improvement scheme is to increase the sheath or use a sheath material with higher hardness, such as TPU, etc., but the scheme can not fundamentally solve the problem, and still has a larger risk of twisting and bulging.

The existing solid structure removes the filling between the gaps of the outer ring of the cable core, and the sheath is extruded to ensure that sheath rubber is filled in the middle of the cable core, the cable core which is easy to loosen is well fixed by the scheme, meanwhile, vertical stripes which are distributed along the axial direction of the wire rod are formed on the inner side of the sheath, and the axial vertical stripes can generate radial anti-torsion force when the wire rod is twisted, so that the radial torsion force is weakened or offset. Due to the fact that the specifications of the cable cores are different in size and the gaps between the cable cores are different in size, the requirement on the concentricity of the sheath is high and is more than 85%, if the concentricity of the sheath cannot meet the requirement, the sheath has a great risk of damaging the core wires and cannot peel off during peeling and processing, and the production and manufacturing cost is increased. Secondly, in the existing solid structure, the isolation layer of the cable core and the sheath adopts a mode of passing talcum powder or oil, the isolation mode has the risk of cable core adhesion, the monitoring requirement on the machining process is strict, the passing talcum powder is easy to generate dust in the wire production and machining processes, the requirement of a dust-free workshop cannot be met, and the oil has certain damage on the cable core insulation and the sheath mechanical property. Finally, the solid structure is only suitable for the charging wire with small wire diameter for alternating current, and the wire with the wire diameter larger than 25mm cannot be used due to factors such as high cost, difficult control of concentricity, difficult sheath peeling and processing and the like.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a gear type anti-twisting soft charging wire for a new energy automobile, which solves the problems of easy twisting, bulging and the like of the existing new energy charging wire, and the temperature rise of the wire rod can be relatively increased, and the wire rod is easy to burn; the requirement of current solid construction charging wire to the sheath concentricity is high, has increased manufacturing cost, and adopts the talcum powder can not satisfy the requirement of dust-free workshop, and solid construction is only applicable to the problem of the charging wire of the little line footpath for the alternating current simultaneously.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides an anti soft charging wire for new energy automobile of twisting of beating of gear type, includes cable core, band and sheath, the band parcel is in the outside of cable core, the sheath is moulded plastics the cover and is established the outside in band, gear type axial vertical stripe has been seted up to the outside of sheath, and gear type axial vertical stripe is at the surface spiral distribution of sheath, it has the filler to fill between cable core and the band.

Preferably, the cable core comprises a plurality of metal wires and insulating covers sleeved outside the metal wires, and the metal wires and the insulating covers are uniformly distributed inside the wrapping belt.
