Abstract
The utility model relates to a spiral double-color insulated wire which comprises a first wire core and a second wire core that is twisted with the first wire core. The first wire core comprises a first insulated sheath and a first conductor provided in the first insulated sheath. The first insulated sheath is obtained through intertwisting a first color strip and a second color strip which are coated on an outer surface of the first conductor and have different colors, thereby forming a circumferential surface. According to the utility model, through twisting two spiral double-color insulated wire according to a using requirement (mainly color code), thereby causing mounting, laying, maintaining and searching operations of more wires which are used in pair to be more convenient, safer and more reliable.
Description
Technical field
The utility model relates to a kind of special electric wire, outstanding reference and the double-colored insulated electric conductor of a kind of spiral.
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 wire cores of traditional orthoscopic is laid maintenance in installation and is searched in the search process, and also difficult identification is easily obscured, especially the place that some two double-colored insulated electric conductor is used in pairs is not very convenient, careless slightly, easily cause and mix wrong the connection, thereby produce circuit, equipment operation fault.Therefore, press for now this double-colored insulated electric conductor is improved.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide the double-colored insulated electric conductor of a kind of spiral, when two double-colored insulated electric conductors of needs use in pairs, is convenient to install, connect, lay, and is easy to identification, searches and search.
The double-colored insulated electric conductor of a kind of spiral described in the utility model, described electric wire comprise 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 and second 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 3rd vitta of the color that is coated in the described second conductor outer surface and the 4th vitta is stranded forms, to form a periphery.
In the double-colored insulated electric conductor of above-mentioned spiral, the material of described first conductor and second conductor is copper.
In the double-colored insulated electric conductor of above-mentioned spiral, 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 double-colored insulated electric conductors, 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. 1 is the structural representation of the double-colored insulated electric conductor of a kind of spiral of the utility model;
Fig. 2 is the structural section figure of the double-colored insulated electric conductor of a kind of spiral of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
See also Fig. 1, Fig. 2, the utility model, the double-colored insulated electric conductor of promptly a kind of spiral, 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 and second vitta, 112 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 3rd vitta 211 of the color that is coated in second conductor, 22 outer surfaces and the 4th vitta 212 stranded forming, to form a periphery.
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.
