Abstract

The utility model discloses a tensile wire. The tensile wire comprises an inner conductor layer and an insulation layer coated outside the conductor layer, wherein at least one nylon wire capable of enhancing the tensile property is further arranged in the conductor layer. The nylon wire adopts a 250-1000D nylon wire, and the nylon wire is positioned in the center position of the conductor layer, thus the problems of fracture of a wire core of the wire and poor tensile property of the whole can be effectively solved, and the service life of the wire can be prolonged.

Description

A kind of pull resistance electric wire

Technical field

The utility model relates to the electric wire art, refers in particular to the strong electric wire of a kind of pull resistance.

Background technology

Present electric wire generally comprises inner conductor layer and is coated on the outer insulating barrier of conductor layer.In the construction site, when using, electric wire needs frequent the movement, therefore tensile property is had higher requirements.But present electric wire resistance to tension is relatively poor, pulls a little energetically just to cause core to break, thereby causes the cycle of scrapping of electric wire very short, needs to change continually, makes the cost of engineering development higher.

The utility model content

In view of this, the utility model is for the disappearance of prior art existence, and its main purpose provides a kind of pull resistance electric wire, the pull resistance of its energy Effective Raise product, thus overcome the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme:

A kind of pull resistance electric wire comprises inner conductor layer and is coated on the outer insulating barrier of conductor layer: also be provided with at least one nylon yarn that can strengthen pull resistance in this conductor layer.

Preferably, described nylon yarn is the 250-1000D nylon yarn.

Preferably, described conductor layer is formed by the assembly of complex root copper wire, and this nylon yarn is positioned at the center of copper wire.

Preferably, described insulating barrier is the sizing material insulating barrier.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, it mainly is to set up nylon yarn in internal conductor layer, core fracture, the relatively poor problem of whole tensile property of electric wire have effectively been solved, the useful life of extending wire.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.

Description of drawings

Fig. 1 is the group sectional view of the embodiment of the utility model.

The accompanying drawing identifier declaration:

10, insulating barrier 20, conductor layer

30, nylon yarn.

Embodiment

Please refer to shown in Figure 1ly, the concrete structure that it has demonstrated the preferred embodiment of the utility model includes insulating barrier 10, conductor layer 20 and nylon yarn 30.Wherein, this conductor layer 20 is the copper wire conductor layer, and it is formed by the assembly of complex root copper wire, and this insulating barrier 10 is the sizing material insulating barrier, and this insulating barrier 10 is coated on outside the conductor layer 20.

Hold, this nylon yarn 30 is selected the nylon yarn of 250-1000D.In the present embodiment, this nylon yarn 30 only is provided with one, and the diameter of this nylon yarn 30 is identical with the brass wire diameter of conductor layer 20, and this nylon yarn 30 is positioned at the center of conductor layer 20, can strengthen the pull resistance of electric wire.In the actual application, the user can arrange the nylon yarn 30 more than two or two as required, and its magnitude setting does not limit.

In sum, design focal point of the present utility model is, it mainly is to set up nylon yarn 30 in internal conductor layer 20, effectively solved core fracture, the relatively poor problem of whole tensile property of electric wire, the useful life of extending wire.

The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment does.
