Description
The technical field is as follows:
the utility model relates to the technical field of cables, more specifically the utility model relates to a novel resistant cable that bends of high strength that says so.
Background art:
the existing cable used in the automobile charging line or other bending-resistant places can be bent for multiple times when in use, and because the existing cable generally adopts foaming materials to fill the gap between the sheath and the cable core, when the cable is bent for multiple times, the bending point of the cable is generally fixed because the cable core does not have enough telescopic space, and the cable is easy to damage after being bent for multiple times at the same position, and the existing cable is bent at 90 degrees in a swinging way, so that the copper conductor in the power line unit can be broken generally for less than 5000 times.
The utility model has the following contents:
the utility model aims at overcoming prior art's not enough, a novel high strength resistant cable that bends is provided, it adopts many cotton threads and power cord unit, the twisted pair unit transposition forms the cable core, and at the outer cladding cotton layer of cable core, the outer cladding restrictive coating of cotton layer, it makes the power cord unit, the space has between twisted pair unit and the many cotton threads, and the cotton thread is loose, it can contract and extend, thereby make the cable body when bending, inside has enough flexible space, make the power cord unit, the twisted pair unit can not the fixed point bend, improve the bending resistance, and service life is prolonged.
The utility model provides a technical problem's scheme is:
a novel high-strength bending-resistant cable comprises a cable body, wherein the cable body comprises a power line unit, a twisted pair unit and a plurality of cotton threads, the power line unit, the twisted pair unit and the plurality of cotton threads are twisted to form a cable core, and a cotton paper layer is coated outside the cable core;
and a sheath layer is fixed on the outer side wall of the cotton paper layer.
The cable body is provided with two power line units and two twisted pair units.
And the outer side wall of the twisted pair unit is coated with an aluminum foil shielding layer.
The power line comprises a copper wire in the middle, and an insulating material layer is coated on the outer wall surface of the copper wire.
The insulating material layer is a PVC insulating layer.
And a gap is formed between the cotton paper layer and the cable core.
The utility model discloses an outstanding effect is:
compared with the prior art, the twisted pair cable has the advantages that the multiple cotton wires are twisted with the power line unit and the twisted pair unit to form the cable core, the cotton paper layer is coated outside the cable core, the sheath layer is coated outside the cotton paper layer, gaps are reserved among the power line unit, the twisted pair unit and the multiple cotton wires, the cotton wires are loose and can be contracted and extended, so that when the cable body is bent, enough telescopic space is reserved inside the cable body, the power line unit and the twisted pair unit cannot be bent at fixed points, the bending resistance is improved, and the service life is prolonged.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the present invention is described in detail below with reference to the attached drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.
In the embodiment, as shown in fig. 1, a novel high-strength bending-resistant cable comprises a cable body, wherein the cable body comprises a power line unit 1, a twisted pair unit 2 and a plurality of cotton threads 3, the power line unit 1, the twisted pair unit 2 and the plurality of cotton threads 3 are twisted with each other to form a cable core, and the outside of the cable core is coated with a cotton paper layer 4;
and a sheath layer 5 is fixed on the outer side wall of the cotton paper layer 4.
Further, the cable body has two power line units 1 and two twisted pair units 2 therein.
Further, the outer side wall of the twisted pair unit 2 is coated with an aluminum foil shielding layer 6.
Further, the power cord 1 includes a copper wire 11 at the middle, and an insulating material layer 12 is coated on the outer wall surface of the copper wire 11.
Further, the insulating material layer 12 is a PVC insulating layer.
Furthermore, a gap is formed between the cotton paper layer 4 and the cable core.
The processing technology of the embodiment is as follows: firstly, twisting copper by a certain number of superfine soft copper wires in strands in a power line unit 1 and a twisted pair unit 2, and then twisting the strands together, for example, the power line unit 1 is twisted by 301 single copper wires with the diameter of 0.08 into 7 strands, the number of each copper wire is 43, and then twisting the 7 stranded copper wires together;
and covering the stranded copper core with an insulating layer with a specified thickness by using an extruder.
The twisted pair elements 2 are then coated with an aluminium foil shield 6.
And then, the two power line units 1, the two twisted pair units 2 and the plurality of cotton threads 3 are twisted together at a certain twist pitch to form a cable core, and then a layer of cotton paper layer 4 is coated to form an isolation layer between the cable core and the sheath.
Finally, a PVC sheath layer 5 is extruded outside the cotton paper layer 4.
It adopts many cotton threads 3 and power cord unit 1, twisted pair unit 2 transposition formation cable core, and at the outer cladding cotton paper layer 4 of cable core, the outer cladding restrictive coating 5 of cotton paper layer 4, it makes power cord unit 1, have the space between twisted pair unit 2 and the many cotton threads 3, and cotton thread 3 is loose, it can contract and extend, thereby make the cable body when bending, inside has enough flexible space, make power cord unit 1, twisted pair unit 2 can not the fixed point bend, improve the bending resistance, and service life is prolonged.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
