The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. Hereinafter, an embodiment of the present utility model will be described in terms of its overall structure.

Referring to fig. 1, an embodiment of the present application provides a pair of photovoltaic cable mechanisms, including:

and the photovoltaic wire groups are formed by twisting the positive photovoltaic wire 1 and the negative photovoltaic wire 2, and a plurality of photovoltaic wire groups are arranged close to each other. Specifically, in the actual operation of those skilled in the art, the outer walls of one positive photovoltaic wire 1 and one negative photovoltaic wire 2 are in contact with each other, so as to form one photovoltaic wire group. A plurality of photovoltaic line groups are close to the setting, and when making, most transposition setting.

The wrapping belt 3 is wrapped with a plurality of photovoltaic wire groups in a twisted mode, and the wrapping belt 3 is arranged on the inner wall of the outer sheath 4 in an penetrating mode. The plurality of photovoltaic wire sets are stranded together, and then the outer wall of the outermost photovoltaic wire set among the plurality of photovoltaic wire sets is provided with the wrapping band 3. An outer sheath 4 is sleeved on the outer wall of the bag belt 3. Thereby forming an integral photovoltaic cable mechanism.

It can be understood that each photovoltaic wire set in the photovoltaic cable mechanism is correspondingly connected with two leads of one photovoltaic cell panel. The connection method may be a normal cable connection method or a connector connection method. The structure that the positive photovoltaic wire 1 and the negative photovoltaic wire 2 are arranged into one photovoltaic wire group can well connect photovoltaic cell panels. And a plurality of photovoltaic line groups are arranged in the wrapping belt 3, so that a plurality of photovoltaic cell panels can be connected simultaneously through the structure. And moreover, the structure of the centralized arrangement of the photovoltaic line groups can enable cables to be tidier when the photovoltaic cell panels are connected, the whole laying site can be tidier and more attractive, and subsequent maintenance is also facilitated.

In the process of manufacturing the photovoltaic string, it is preferable that the outer walls of the positive photovoltaic string 1 and the negative photovoltaic string 2 within the photovoltaic string are set to two different colors for distinguishing them. The photovoltaic line group is provided with the positive photovoltaic line 1 and the negative photovoltaic line 2 with different outer wall colors, and different colors can be distinguished more conveniently in the process of connecting the photovoltaic line group with the photovoltaic cell panel.

In one implementation manner of this embodiment, the outer walls of the photovoltaic wire groups formed by twisting the positive photovoltaic wire 1 and the negative photovoltaic wire 2 are protected, and preferably, the isolation layer 5 is sleeved on the outer wall of each photovoltaic wire group. The arrangement of the isolation layer 5 can isolate and distinguish a plurality of photovoltaic line groups, and meanwhile, the protection effect on the positive photovoltaic line 1 and the negative photovoltaic line 2 is also achieved. Specifically, in the transportation, laying and subsequent use processes, friction exists between the positive photovoltaic wire 1 and the negative photovoltaic wire 2 in one photovoltaic wire group in the cable, and friction phenomenon also occurs between the positive photovoltaic wire 1 and the negative photovoltaic wire 2 in different photovoltaic wire groups. The long-time friction can damage the outer walls of the falling positive electrode photovoltaic wire 1 and the falling negative electrode photovoltaic wire 2, and further expose the internal conductor structure. Such conditions can lead to electrical leakage inside the cable and to local overheating, causing internal-to-external burning, damaging the structure of the whole cable, and causing loss of property.

In summary, the outer wall of the photovoltaic wire group made of the positive photovoltaic wire 1 and the negative photovoltaic wire 2 is coated with the isolation layer 5, so that the plurality of photovoltaic wire groups can be prevented from being damaged by friction when being twisted and laid. The internal structure of the cable is further rationalized, so that the connection of the photovoltaic cell panel is more convenient.

When processing the cable, the taping 3 is preferably made of non-woven fabric or polyester. The bag belt 3 can integrate and restrict the photovoltaic wire groups, so that the relative positions of the plurality of photovoltaic wire groups after being twisted can be more stable. Meanwhile, the photovoltaic line group can be protected. The non-woven fabric has the characteristics of moisture resistance, flexibility, thinness, flame retardance, low price and recycling; the polyester has the characteristics of good heat resistance, high tensile strength and high ageing resistance. So that the belt 3 can be produced according to the use requirement.

Preferably, the outer sheath 4 is made of polyvinyl chloride or polyolefin. It is understood that polyvinyl chloride has good corrosion and abrasion resistance with polyolefins. After the outer sheath 4 is manufactured, further, the outer wall of the outer sheath 4 is polished. The outer sheath 4 after the polishing process has a smoother outer wall. The cabling environment is generally complex and suffers from many unpredictable situations. The outer wall of the smooth outer sheath 4 can prevent the cable from being rubbed and damaged during transportation and use, so that the cable is scrapped in advance, and the smooth outer wall enables insects, mice and the like to be difficult to gnaw, and further plays a role in protecting the cable.

In summary, the wrapping tape 3 made of non-woven fabrics or polyester and the outer sheath 4 made of polyvinyl chloride or polyolefin can greatly reduce the damage to the cable in the process of laying the cable, and can effectively prolong the service life of the cable in the process of using the cable.

Preferably, the plurality of photovoltaic wire sets are digitally marked in sequence, the digital marks are arranged on the outer walls of the positive photovoltaic wire 1 and the negative photovoltaic wire 2, and the digital marks on the positive photovoltaic wire 1 and the negative photovoltaic wire 2 are the same. In another embodiment of the present application, an isolation layer is disposed on the outer wall of the photovoltaic wire set, so that protection and differentiation can be performed on different photovoltaic wire sets. In order to enhance the discrimination between different photovoltaic wire sets, a digital marking method is used in this embodiment. Specifically, each photovoltaic line group is digitally marked in sequence, and the digital marks are arranged on the outer walls of the positive photovoltaic line 1 and the negative photovoltaic line 2 in the photovoltaic line group. That is, the positive electrode photovoltaic wire 1 and the negative electrode photovoltaic wire 2 are digitally marked, and then the photovoltaic wire group after the positive electrode photovoltaic wire 1 and the negative electrode photovoltaic wire 2 are twisted is marked. It is noted that the numbers on the positive electrode photovoltaic line 1 and the negative electrode photovoltaic line 2 are the same, and the positive electrode photovoltaic line 1 and the negative electrode photovoltaic line 2 in different photovoltaic line groups are marked differently and are marked sequentially.

In summary, the digital mark is disposed on the photovoltaic string, specifically, the positive photovoltaic string 1 and the negative photovoltaic string 2 disposed in the photovoltaic string. The number marks of the positive electrode photovoltaic wire 1 and the negative electrode photovoltaic wire 2 in the same photovoltaic wire group are the same, and the number marks of the positive electrode photovoltaic wire 1 and the negative electrode photovoltaic wire 2 in different photovoltaic wire groups are different and marked in sequence. The arrangement of the digital marks enables the photovoltaic line groups to be distinguished more easily, and the efficiency of the cable laying is greatly improved.
