Abstract

The invention discloses an electrical wire with embroider moulages, aiming to solve the problems that adhesive force between an insulation coat and a wire core is small, and the insulation coat at an kerf is easy to shrink so that hidden electricity leakage risks are high in an existing electric wire. The electrical wire with the embroider moulages comprises a wire core and an insulation coat and is structurally characterized in that a plurality of the embroider moulages are arranged on the wire core, and protrusions matching with the embroider moulages of the wire core is arranged on the inner wall of the insulation coat. The embroider moulages are arranged on the wire core so as to enhance the adhesive force between the insulation coat and the wire core, and using risks due to the fact that the insulation coat shrinks after a manipulator is used to peel the insulation coat are prevented.

Description

A kind of electric wire with embroider impression

Technical field

The present invention relates to a kind of electric wire with embroider impression.

Background technology

Existing electric wire is as shown in Figure 1, comprises core and insulated hull, when needing wiring; Generally remove one section insulated hull, directly wiring then, the time is long slightly; Because the stress of insulated hull self, adhesive force is little between insulated hull and the core, can shrink a bit of distance automatically in incision; Cause core exposed outside, thereby electric shock accidents perhaps take place in electric leakage easily.

Summary of the invention

For adhesive force between the insulated hull that overcomes existing electric wire and the core little; The insulated hull of incision shrinks easily; Thereby have the dangerous deficiency of electric leakage, the present invention aims to provide a kind of electric wire with embroider impression, and this electric wire is through being provided with the embroider impression on core; Increase the adhesive force between insulated hull and the core, avoid dangerous generation.

To achieve these goals, the technical scheme that the present invention adopted is:

A kind of electric wire with embroider impression comprises core and is wrapped in the insulated hull on the core, and its design feature is, has a plurality of embroider impressions on the said core, has the projection that matches with the embroider impression of core on the inwall of said insulated hull.

Because the existence of embroider impression, the adhesive force between insulated hull and the core is improved greatly, does not have the phenomenon of insulated wire retraction behind the tangent line.

As a kind of concrete form of embroider impression, said embroider impression is the groove perpendicular to the core axial line.

For the bigger electric wire of wire core diameter with embroider impression, for more firmly with insulated hull attached on the core, groove design is a vee gutter.

For the less electric wire of wire core diameter, in order to guarantee core intensity, groove design is a dovetail groove.

Generally speaking, adjacent two embroider impression spacings are 1mm ~ 10mm, more preferably 3mm ~ 5mm.

According to the purposes of electric wire, generally said embroider impression is arranged on the two sides up and down of core.

By said structure; The present invention is through being provided with the embroider impression on core; Increased the adhesive force between core and the insulated hull,, used manipulator to peel off the use unsafe condition that insulate and shrink and cause in the insulation back thereby avoided line to come to plug type bus duct characteristics easy for installation.

In manufacture process, insulated hull extruded increases by one cotton ginning technique before the operation, and online wicking surface compacting one deck decorative pattern comes after insulated hull extrudes line, and insulated hull infiltrates core decorative pattern place, thus the adhesive force between increasing core and insulating.

Compared with prior art, the invention has the beneficial effects as follows:

1, the present invention increases the adhesive force between insulated hull and the core through the embroider impression is set on core, and after having solved the use manipulator and peeling off insulated hull, insulated hull shrinks and the dangerous problem of use that causes.

2, compare than the conventional mounting mode of connection, this kind cotton covered wire adopts modular to install, and (5 meters or 10 meters one section uses) are convenient to install.

3, be convenient to reclaim, after engineering was accomplished, the dismantled and assembled recovery continued of this electric wire was used.

Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.

Embodiment

Embodiment 1

A kind of electric wire with embroider impression like Fig. 1 and 2, shown in 3, comprises core 1 and is wrapped in the insulated hull 2 on the core 1; Have a plurality of embroider impressions 3 on the said core 1, core 1 diameter is 1.8mm, has the projection that matches with the embroider impression 3 of core 1 on the inwall of said insulated hull 2; The said embroider impression 3 that is arranged on the two sides up and down of core 1 is the groove perpendicular to core 1 axial line; Because 1 diameter of core is thinner relatively, therefore in order to guarantee the intensity of core 1, simultaneously in order to keep the adhesive force of 2 pairs of cores 1 of insulated hull; This groove design is a dovetail groove, and adjacent two flute pitch are 5mm.

Said groove does.

Embodiment 2

A kind of electric wire with embroider impression, core 1 diameter is 2.8mm, like Fig. 1 and 4, shown in 5; Its structure is similar with embodiment 1, and difference is, because wire core diameter is bigger; Adhesive force for the ease of 2 pairs of cores 1 of insulated hull is bigger, is vee gutter with groove design.

The content that the foregoing description is illustrated is to be understood that to these embodiment and only is used to be illustrated more clearly in the present invention; And be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
