Description

A wire with a through core and a mark

technical field

The utility model relates to electric wires, in particular to a core-penetrating and marked electric wire.

Background technique

The electric wire that is generally used at present generally all is to adopt plastic protection layer, promptly is provided with colorless and transparent plastic protection layer or the plastic protection layer with color on metal wire, beam surface. Wires with a colorless and transparent plastic protective layer are free of recycled materials, which reassures consumers, but does not allow consumers to distinguish the function or use of the wire; colored plastic protective layer allows consumers to distinguish the function or use of the wire, but increases It makes it more difficult for consumers to distinguish the quality of wires, such as using recycled materials to add color as a protective layer, and using primary recycled metals as cores, etc. Such wires are prone to aging and overloading, which increases hidden dangers to use safety.

Utility model content

The purpose of this utility model is to provide a wire with a core through the core and with markings, so that consumers can not only be assured of the quality of the wire, but also distinguish the function or use of the wire.

In order to achieve the above object, the technical scheme of the utility model is as follows:

The core-through and marked electric wire proposed by the utility model includes a core wire and an outer protective layer coated on the outer wall of the core wire; the outer protective core-through layer and the outer protective marking layer are respectively axially coated on the outer wall of the core wire , forming a whole covering the outer wall of the core wire, and jointly constituting the outer protective layer. That is, the outer protective layer seen on any cross-section of the core-through-marked electric wire is composed of an outer protective core-through layer and an outer protective marking layer.

The outer protective layer is compounded by simultaneously extruding hot-melt plastics into a composite mold from two extruders, one of which extrudes transparent colorless plastic as the outer protective core layer; the other extrudes Colored plastic is used as the outer protective marking layer; the outer protective transparent core layer and the outer protective marking layer are integrally covered on the outer wall of the core wire to obtain a core wire that can be seen and has a marking function of wires. The outer protective marking layer may also be colored paint.

The structure of the marked electric wire proposed by the utility model can also be: comprising a core wire and an outer protective layer coated on the outer wall of the core wire; the outer protective core layer is coated on the outer wall of the core wire, and the outer protection is transparent Part of the outer wall of the core layer is axially coated with an outer protective marking layer, and the outer protective core layer and the outer protective marking layer together constitute the outer protective layer. That is, the outer protective layer seen on any cross-section of the core-through and marked electric wire is composed of an outer protective core layer and an outer protective marking layer, and the outer protective marking layer is coated on the outer protective transparent layer. Part of the outer wall of the core layer.

The outer protective layer is formed by extruding hot-melt transparent plastic from an extruder and covering the outer wall of the core wire through a mold to form an outer protective core layer, and then spray-printing colored plastic or Colored paint, etc. are used as the outer protective marking layer to obtain a wire that can not only see the core wire, but also has the marking function. The outer protective core layer is transparent and colorless plastic; the outer protective marking layer is colored plastic or colored paint; the outer protective marking layer is in the shape of lines or dotted lines along the axial direction, and can be one or more than one.

The electric wires of the above two structures have not only prevented manufacturers from shoddy, but also allow consumers to use them conveniently. The core-penetrating and marked electric wires may be electric wires and signal wires with various functions and cross-sectional shapes.

Compared with the prior art, the beneficial effect of the utility model is that it is convenient for consumers to identify the quality of electric wire products, and it is convenient for consumers to distinguish the functions or uses of electric wires.

Detailed ways

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is further described.

Embodiment one

As shown in Figure 1. Select a copper wire with a diameter of 5mm as the core wire 1; use two extruders to extrude hot-melt plastic at the same time, one extrudes transparent colorless PVC plastic as the outer protective core layer 2, and the other extrudes colored PVC plastic As the outer protective marking layer 3, the outer wall of the core wire 1 is covered by a compound mold to obtain a marked wire with a diameter of 9 mm and penetrating the core. The prepared core-through and marked electric wire structure includes a core wire 1 and an outer protective layer covering the outer wall of the core wire 1; the outer protective core-through layer 2 and the outer protective marking layer 3 are respectively axially coated on the core wire The outer wall of the core wire 1 is formed as a whole covering the outer wall of the core wire 1, and jointly constitutes the outer protective layer.
