Abstract
The invention discloses a separable photovoltaic cable with multiple cores parallelly distributed and belongs to the technical field of electric wires and cables. The separable photovoltaic cable comprises a group of cable bodies and a lacerable cable connection body, wherein the group of cable bodies comprises two or more than two cable bodies which are the same in structure, and each cable body is formed by a conductor, an insulating layer outside the conductor and a jacket layer arranged outside the insulating layer. The separable photovoltaic cable is characterized in that the cross section of the lacerable cable connection body is in an 8 shape, the colors of the insulation layers of the group of cable bodies are different, and the colors of the jacket layers of the group of cable bodies are the same. The separable photovoltaic cable has the advantages that the jacket layers cannot be damaged in tearing and cannot crack naturally due to twisting or other external force in a non-tearing state so that cracking of the lacerable cable connection body caused by accident factors is avoided, production efficiency is improved and construction is facilitated, distinguishing in installation construction and following inspection and maintenance are facilitated, and the problem that the insulation layers cannot be distinguished due to time duration is solved.
Description
Technical field
The invention belongs to technical field of electric wires and cables, be specifically related to a kind of detachable photovoltaic cable of multicore parallel arranged
Background technology
are along with the continuous enhancing of the mankind to the economy consciousness and the protection consciousness of the non-renewable resources such as coal, oil, natural gas and even ocean ice; Thereby utilization inexhaustible and solar energy environmental protection is paid attention to day by day, and solar photovoltaic generation system is an illustration.Solar photovoltaic generation system need use photovoltaic cable; Because solar photovoltaic generation system is used in harsh and unforgiving environments such as high temperature and ultraviolet radiation etc.; Therefore; In order to ensure that photovoltaic cable is able under-40 ℃-120 ℃ adverse circumstances, transmit power supply for a long time and stably, the corresponding solar photovoltaic cable standard of having issued in countries in the world.
are no lack of in disclosed Chinese patent document about the technical information of photovoltaic cable and are seen in; Wherein, Distinguish and the technical information of being convenient to the construction of cable of installation aspect can be seen in disclosed Chinese patent document equally around solar energy electroplax wiring polarity; Typical in CN202159503U disclosed " the detachable photovoltaic cable of twin-core splayed configuration "; This patent scheme be with two groups promptly the outer wall of the restrictive coating of two cables connect by the connector of a rhombus each other; And squeeze on the surface of the restrictive coating of each cable and to attach the sign that markings connect as polarity of electrode, or on the restrictive coating surface of cable spray printing electric polarity sign continuously.Though this patent has the 0013rd to 0016 section alleged technique effect of specification; But there is following shortcoming: owing to connect by the connector of rhombus each other between the restrictive coating of two (patent is claimed two lines) cables; Therefore when two electrical cables separate, cause the restrictive coating of cable damage to occur at the connector position easily, promptly cause the jacket surface damage of cable connector place.Again, attach markings or continuous spray printing one strip electrode polarity mark, therefore, when many cable parallel arranged, then can't realize differentiation polarity of electrode surperficial the squeezing of the restrictive coating of cable.
In view of above-mentioned prior art, be necessary to improve, for this reason, the applicant has done useful design, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention be to provide a kind of help to improve produce and the efficiency of construction when using, help avoiding the restrictive coating of damage cable when separating and be of value to the detachable photovoltaic cable of the multicore parallel arranged of when the terminal box terminal location wiring of solar photovoltaic generation system, distinguishing polarity of electrode and convenient follow-up inspection easily at the connector place.
task of the present invention is accomplished like this; A kind of detachable photovoltaic cable of multicore parallel arranged; The cable torn connector between the said restrictive coating that comprises structure identical two or above and each one group of cable body that constitutes by conductor, insulating barrier and the restrictive coating outside insulating barrier outside conductor and be connected in the adjacent cable body; Be characterised in that: the described shape of cross section of tearing the cable connector is 8 fonts of Arabic numerals; The color of the said insulating barrier of described one group of cable body has nothing in common with each other, and the color of the restrictive coating of described one group of cable body is identical.
are in a concrete embodiment of the present invention; The described cable connector of tearing comprises that first combines bead, second to combine bead and tear neck; First combines the said restrictive coating of bead and described cable body to be combined as a whole; Second combines the bead and the restrictive coating of adjacent cable body to be combined as a whole, and is connected between first, second combination bead and tear neck.
In another concrete embodiment of the present invention, described conductor constitutes by the complex root tinned copper wire is stranded
.
in another concrete embodiment of the present invention, described insulating barrier is a low smoke and zero halogen cross-linking radiation polyolefin.
in another concrete embodiment of the present invention, described restrictive coating is a low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.
also have among the concrete embodiment of the present invention, and the color of described restrictive coating is a black.
One of
technique effect that technical scheme provided by the invention had; Because can tear the structural design of cable connector is that shape of cross section is 8 fonts; Therefore undermine restrictive coating tearing Shi Buhui; And can natural cracking occur because of distortion or other external force non-tear under the state not, avoid non-artificial factor to cause to tear cable connector cracking; Two since cable body have parallel two or more than, therefore help to enhance productivity and convenient construction; Three because the color of the insulating barrier of one group of cable body has nothing in common with each other, again because the color of restrictive coating is identical, differentiation when therefore helping installation and follow-up inspection, and not can because of the time cause the color of insulating barrier to be unable to recognize for a long time problem.
Description of drawings
Fig. 1 is the cross sectional representation of the first embodiment of the present invention.
Fig. 2 is the enlarged drawing of the cable torn connector shown in Figure 1
Fig. 3 is the cross sectional representation of the second embodiment of the present invention.
Embodiment
Embodiment 1:
Fig. 1 and Fig. 2 are asked for an interview in
, in Fig. 1, have provided the identical and parallel a pair of cable body 1 of structure, and each cable body 1 comprises conductor 11, insulating barrier 12 and restrictive coating 13; Conductor 11 constitutes by the zinc-plated thin copper wire of complex root is stranded; Insulating barrier 12 is a low smoke and zero halogen cross-linking radiation polyolefin, squeezes to overlay on the conductor 11, promptly squeezes to overlay on outside the conductor 11; Restrictive coating 13 is a low-smoke non-halogen flame-retardant cross-linking radiation polyolefin, squeezes to overlay on outside the insulating barrier 12.Wherein: the color of the insulating barrier 12 of two cable bodies 1 is different, and the color of restrictive coating 13 is a black.Preferably, the color of insulating barrier 12 is the color except that black.For example when the color of the insulating barrier 12 of a cable body 1 when being red, the color of the insulating barrier 12 of another root cable body 1 be a yellow so, and vice versa.
