Abstract
The utility model discloses a bending-resistant copper wire. The bending-resistant copper wire comprises a copper wire conductor layer, a crosslinked polyethylene insulating layer is extruded outside the copper wire conductor layer, multiple reinforcing layers are distributed outside the crosslinked polyethylene insulating layer, the inside of the reinforcing layers is filled with PU buffering materials, and an insulating sheath is extruded outside the reinforcing layers. The reinforcing layers are hollow and formed by braiding galvanized steel wires. Due to such structure, relatively strong pressure in the contact surface is resistant, the copper wire is prevented from break due to wearing, and the copper wire has relatively high bending resistance and excellent flexibility, and can be applied to various occasions.
Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of copper cash of bend resistance.
Background technology
Cable in the process using due to the needs of operational environment, need to carry out curved arrangement, in the time of bending, twisted wire has stronger interface pressure each other, the wearing and tearing broken string easily rubbing and cause, therefore need it to there is higher bending durability for this cable, and viewpoint from easily connecting up, the pliability of having relatively high expectations, the existing construction of cable is difficult to realize high bending durability and high pliability simultaneously.。
In view of this, the inventor, for the above-mentioned defect further investigation of copper cash in prior art, has this case to produce then.
Utility model content
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of twisted wire interface pressure each other that reduces, and can suppress to cause because of bending the copper cash of wearing and tearing broken string.
In order to reach above-mentioned object, the utility model adopts following concrete technical scheme:
A kind of copper cash of bend resistance, it comprises copper conductors layer, described copper conductors layer is extruded with a crosslinked polyetylene insulated layer outward, described crosslinked polyetylene insulated layer outside is distributed with several reinforced layers, in described reinforced layer, be filled with padded coaming, and be extruded with an insulating sleeve outward at each reinforced layer, described reinforced layer is woven into hollow shape by zinc-coated wire.
Described padded coaming adopts PU.
The utility model advantage is compared with prior art: owing to being provided with above structure, the utility model solves compared with strong contact surface pressure, prevents that copper cash from wearing and tearing and breaking, and possesses high bend resistance, can show again excellent flexibility, can be applicable to multiple occasion and use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Embodiment 1:
Shown in Fig. 1, a kind of copper cash of bend resistance, it comprises copper conductors layer 1, the outer crosslinked polyetylene insulated layer 2 that is extruded with of described copper conductors layer 1, described crosslinked polyetylene insulated layer 2 outside are distributed with several reinforced layers 3, in described reinforced layer 3, be filled with PU padded coaming 4, and outside each reinforced layer 3, be extruded with an insulating sleeve 5, reinforced layer 3 becomes reinforced layer 3 by zinc-coated wire at PU padded coaming surface weave, can increase copper cash bend resistance ability, solve again compared with strong contact surface pressure, prevent that copper cash from wearing and tearing and breaking.
But above-mentioned embodiment is exemplary, be to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.
Claims (2)
1. the copper cash of a bend resistance, it comprises copper conductors layer, it is characterized in that: described copper conductors layer is extruded with a crosslinked polyetylene insulated layer outward, described crosslinked polyetylene insulated layer outside is distributed with several reinforced layers, in described reinforced layer, be filled with padded coaming, and be extruded with an insulating sleeve outward at each reinforced layer, described reinforced layer is woven into hollow shape by zinc-coated wire.
2. a kind of copper cash of bend resistance as claimed in claim 1, is characterized in that: described padded coaming adopts PU.
