Abstract

The utility model relates to an energy-saving signal wire which comprises a jacket, a shielding layer and a metal lead, wherein the meal lead is externally covered with an insulating layer and comprises a first wire core made of steel material or aluminum material, and a second wire core that is covered outside the first wire core and made of copper; and the first wire core and the second wire core are combined together in a way of extrusion molding. By utilizing the wire core which is made of steel material or aluminum material and covered by the wire core made of the copper to replace the original pure copper wire core, the energy-saving signal wire has good using performance and simple structure, effectively saves the copper resource, and is relatively low in cost.

Description

A kind of energy-conservation holding wire

Technical field

The utility model relates to a kind of holding wire, relate in particular to a kind of can effectively energy-conservation holding wire.

Background technology

As everyone knows, because the resistivity of copper is low, conduct electricity very well, the characteristics that signal distortion is little, be widely used as the carrier of various signal transmission, development along with electronic information technology, various electronic equipments are applied to each corner in the world, link up between the people more convenient, yet be accompanied by the development of electronic information technology, a large amount of copper materials are consumed, will certainly cause global copper material resource anxiety, and the price of copper is also higher relatively, uses for limited copper resource obtains maximum limit, and market presses for a kind of substitute and is born.

Be directed to above-mentioned situation, be necessary to provide a kind of energy-conservation holding wire in fact, this holding wire not only serviceability is good, and simple in structure, can save the copper resource effectively, and cost is low relatively, to overcome the defective of light fixture in the prior art.

The utility model content

The purpose of this utility model just provides a kind of energy-conservation holding wire, and this holding wire not only serviceability is good, and simple in structure, can save the copper resource effectively, and cost is low relatively.

For reaching above-mentioned purpose, the utility model provides a kind of energy-conservation holding wire, this energy-conservation holding wire comprises sheath, screen and plain conductor, described plain conductor is coated with insulating barrier, wherein, described plain conductor comprises first core and is coated on second core outside first core that described second core is a copper core.

Especially, described first core is a steel wire core, and combines with second core by extrusion molding.

Especially, described first core is a thread core of aluminum, and combines with second core by extrusion molding.

Compared to prior art, the utility model provides a kind of energy-conservation holding wire, this holding wire utilizes copper core to coat other metal material cores to replace original fine copper core, not only serviceability is good, and it is simple in structure, can save the copper resource effectively, cost is low relatively, for enterprise has brought more benefit.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the profile of the utility model one preferred embodiment,

Among the figure:

1, sheath; 2, screen; 3, insulating barrier; 4, plain conductor; 40, first core; 41, second core.

Embodiment

Please refer to shown in Figure 1ly, Fig. 1 is the profile of the utility model one preferred embodiment.

The utility model provides a kind of energy-conservation holding wire, this holding wire comprises sheath 1, screen 2 and plain conductor 4, described sheath 1 is arranged at outside the screen 2, be provided with most in the described screen 2 with plain conductor 4, the described plain conductor 4 outer insulating barriers 3 that all are coated with, in present embodiment, be provided with three plain conductors 4 in the described screen 2, described plain conductor 4 comprises first core 40 and is coated on second core 41 outside first core 40, in present embodiment, described first core 40 can be steel matter or aluminium material plain conductor, described second core 41 is the copper material plain conductor, and with the use amount of minimizing copper product, and the mode that described first core 40 passes through extrusion molding combines with second core 41.

Above-mentioned energy-conservation holding wire utilizes copper core cladding steel material or aluminium material core to replace original fine copper core, and not only serviceability is good, and simple in structure, can save the copper resource effectively, and cost is low relatively, for enterprise has brought more benefit.

Fig. 1 is the profile of the utility model one preferred embodiment; but the utility model is saved arrangement mode and this a kind of shape that the holding wire of cost is not limited to this a kind of assembly; as shown in Figure 1; satisfying on the basis of its function; can be along with the change of the shape of plain conductor and connected mode and change; the change that anyone makes arrangements of components mode of the present utility model, model and shape on principle of the present utility model basis has easily then all fallen into protection range of the present utility model.
