Abstract

The utility model relates to a three-color insulating twisted-type flexible electric wire, which comprises a first wire core and a second wire core twisted with the first wire core; the first wire core comprises a first insulating sheath and a first conductor arranged in the first insulating sheath; the first insulating sheath is formed through the twisting of a first color bar, a second color bar and a third color bar, so as to form a circumference surface, wherein the first color bar, the second color bar and the third color bar are coated on the external surface of the first conductor and have different colors. Through the twisting of two screw-type three-color insulating wire cores according to the using requirements, the mounting, the laying, the maintenance and the searching of more electric wires used in pairs are convenient, safe and reliable.

Description

A kind of three looks insulation strand type cord

Technical field

The utility model relates to a kind of special electric wire, outstanding reference and a kind of three looks insulation strand type cord.

Background technology

In the development of human society process of construction, in the various facilities that vary in size, using the electric wire (or cable) that cross-sectional area of conductor has a very wide distribution, radical (or core number) is various in the circuit of used various instrument and meters, telecommunications control and supply network.Because painted being at most usually about ten kinds of insulation, for tens of hundreds of even electric wire or insulated wire cores of thousands of, difficult identification far away, thus electric wire installation lay with the maintain and replace process in resolution identification become a difficult problem.

Traditional method of distinguishing electric wire is that numeral is imprinted on electric wire or the insulated wire cores surface, still, adopts this method, lays in installation, keeps in repair and search in the search process all very inconveniently, and especially in the place of the low light level, this defective is more obvious.The double-colored insulated electric conductor of traditional orthoscopic lays maintenance in installation and searches in the search process, and also difficult identification is easily obscured.After orthoscopic three look insulated electric conductors come out, though solved more radicals wirings identification, search the search problem, to the place that some two three look insulated electric conductor uses in pairs, not very convenient.Careless slightly, easily cause and mix wrong the connection, thereby produce circuit, equipment operation fault.

The utility model content

In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of three looks insulation strand type cord, when two three look insulated electric conductors of needs use in pairs, is convenient to install, connect, lay, and is easy to identification, searches and search.

A kind of three looks insulation strand type cord described in the utility model, described electric wire comprises first core and the second stranded with it core,

Described first core comprises first insulating sleeve and is arranged on the first interior conductor of this first insulating sleeve, described first insulating sleeve is by mutually different first vitta of the color that is coated in the described first conductor outer surface, second vitta and the 3rd vitta is stranded forms, to form a periphery;

Described second core comprises second insulating sleeve and is arranged on the second interior conductor of this second insulating sleeve, described second insulating sleeve is by mutually different the 4th vitta of the color that is coated in the described second conductor outer surface, multicolored bar and the 6th vitta is stranded forms, to form a periphery.

In above-mentioned three looks insulation strand type cord, the material of described first conductor and second conductor is copper.

In above-mentioned three looks insulation strand type cord, the material of described first insulating sleeve and second insulating sleeve is polyvinyl chloride.

Owing to adopted above-mentioned technical solution, the utility model passes through two spiral three look insulated wire cores, twist together by instructions for use (mainly referring to colour code), thereby the installation of more electric wires of paired use is laid, keep in repair and search search and become very convenient, safe, reliable.

Fig. 2 is the structural section figure of a kind of three looks insulation of the utility model strand type cord.

Embodiment

Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.

See also Fig. 1, Fig. 2, the utility model, promptly a kind of three looks insulation strand type cord, it comprises first core 1 and the second stranded with it core 2, wherein,

First core 1 comprises first insulating sleeve and is arranged on the first interior conductor 12 of this first insulating sleeve, first insulating sleeve is by mutually different first vitta 111 of the color that is coated in first conductor, 12 outer surfaces, second vitta 112 and the 3rd vitta 113 stranded forming, to form a periphery;

Second core 2 comprises second insulating sleeve and is arranged on the second interior conductor 22 of this second insulating sleeve, second insulating sleeve by mutually different the 4th vitta 211 of the color that is coated in second conductor, 22 outer surfaces, multicolored bar 212 and the 6th vitta 213 stranded forming, to form a periphery.

First conductor 12 in the utility model and the material of second conductor 22 are copper; The material of first insulating sleeve and second insulating sleeve is polyvinyl chloride.

Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.

Claims (3)
