Description

A kind of tracing line

Technical field

The utility model relates to a kind of wire, particularly a kind of tracing line.

Background technology

Underground piping needs the position of accurately following the tracks of pipeline after laying, can confirm the position of pipeline smoothly when keeping in repair; Now usually use nonmetal pipeline, need to bury tracing line underground in the position of piping laying when being embedded in underground simultaneously, by tracing line follow-up mechanism, tracing line is followed the trail of, thus determine the accurate location of pipeline; Existing tracing line is made up of heart yearn, conductive layer and insulating barrier; Heart yearn, is made up of steel wire or steel strand wire, is arranged at the center of tracing line, for guaranteeing the tensile strength of tracing line; Conductive layer, be made up of at the copper of heart yearn appearance plating, heart yearn is wrapped to form the thin layer of conduction by copper; Insulating barrier, is made up of insulating material, in being wrapped in by conductive layer, makes conductive layer and exterior insulation, and protects conductive layer not by extraneous corrosion.

The shortcoming of existing tracing line is: directly pass through plate bonding between heart yearn and the copper of conductive layer, easily rust spot is there is in heart yearn before electroplating operations, the reliability of electroplating operations is reduced, the situation being separated between conductive layer with heart yearn, peeling off easily is there is after plating, particularly tracing line more easily occurs after using for a long time, causes tracing line loss of function.

Utility model content

The utility model is to overcome defect in above-mentioned prior art, and form intermediate layer by the electroplating nickel on surface at heart yearn, the re-plating of copper conductive layer, in the outside in intermediate layer, makes the connection of conductive layer and heart yearn more reliable.

A kind of tracing line of the present utility model, comprises heart yearn, conductive layer, intermediate layer and insulating barrier; Heart yearn, is made up of steel wire or steel strand wire, is arranged at the center of tracing line, for guaranteeing the tensile strength of tracing line; Intermediate layer, the thin layer of the cladding core wire that the surface being plated on heart yearn by nickel is formed; Conductive layer, the thin layer in the coated intermediate layer that the outside being plated on intermediate layer by copper is formed; Insulating barrier, is made up of insulating material, in being wrapped in by conductive layer, makes conductive layer and exterior insulation, and protects conductive layer not by extraneous corrosion.

In technique scheme, the thickness in intermediate layer, between 20 to 30 microns, makes intermediate layer both have the stable effect connecting heart yearn and conductive layer, can also have conducting function concurrently simultaneously.

In technique scheme, the thickness of conductive layer is between 100 to 200 microns.

Compared with prior art, the utility model forms intermediate layer by the electroplating nickel on surface at heart yearn, and the re-plating of copper conductive layer is in the outside in intermediate layer, and make the connection of conductive layer and heart yearn more reliable, intermediate layer also has conducting function concurrently simultaneously.

Accompanying drawing explanation

Fig. 1 is the stereogram of a kind of tracing line of the utility model.

Mark the following drawings mark thereon by reference to the accompanying drawings:

1-heart yearn, 2-intermediate layer, 3-conductive layer, 4-insulating barrier.

Embodiment

Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model not by the restriction of embodiment.

A kind of tracing line of the utility model as shown in Figure 1, comprises heart yearn 1, conductive layer 3, intermediate layer 2 and insulating barrier 4; Heart yearn 1, is made up of steel wire or steel strand wire, is arranged at the center of tracing line, for guaranteeing the tensile strength of tracing line, meets the requirement of strength of tracing line under various different environment; The thin layer of the cladding core wire that the surface that intermediate layer 2 is plated on heart yearn by nickel is formed; Conductive layer 3, the thin layer in the coated intermediate layer that the outside being plated on intermediate layer by copper is formed; Insulating barrier 4, is made up of the PE material insulated, and in being wrapped in by conductive layer, makes conductive layer and exterior insulation, and protects conductive layer not by extraneous corrosion.

Further as shown in Figure 1, the thickness in intermediate layer 2, between 20 to 30 microns, makes intermediate layer both have the stable effect connecting heart yearn and conductive layer, can also have conducting function concurrently simultaneously; The thickness of conductive layer 3 is between 100 to 200 microns.

The utility model forms intermediate layer by the electroplating nickel on surface at heart yearn, and the re-plating of copper conductive layer is in the outside in intermediate layer, and make the connection of conductive layer and heart yearn more reliable, intermediate layer also has conducting function concurrently simultaneously.

Be only a specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection range of the present utility model.
