[0011] Figure 1 It is the structural schematic diagram of the utility model;

[0012] Figure 2 The structure diagram of the adjacent cable wiring of the utility model is shown in the figure.

[0013] In the figure: 1 conductor, 2 insulation layer, 3 inner sheath layer, 4 flame-retardant layer, 5 waterproof layer, 6 outer sheath layer, 7 pre-break mark, 8 protective sleeve, 9 cable. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0015] As shown in Figure 1 and Figure 2 A novel photovoltaic cable, comprising a conductor 1, an insulation layer 2 is arranged outside the conductor, an inner sheath layer 3 is arranged outside the insulation layer, a flame-retardant layer 4 is arranged outside the inner sheath layer, an outer sheath layer 6 is arranged outside the flame-retardant layer, a plurality of groups of uniformly arranged pre-break marks 7 are arranged along the length direction of the inner sheath layer and the outer sheath layer in the direction from the inner side to the outer side. A waterproof layer 5 is further arranged between the flame-retardant layer and the outer sheath layer.

[0016] Further, a protective sleeve 8 is further arranged between the adjacent cables, the protective sleeve is arranged between the inner sheath and the outer sheath, a waterproof structure and a flame-retardant structure are arranged inside the protective sleeve, the waterproof structure and the flame-retardant structure can be a waterproof coating and a flame-retardant coating, an adhesive layer is arranged outside the protective sleeve, used for bonding the outer sheath layer. The protective sleeve is a flexible structure with the first end and the second end clamped.

[0017] Further, the pre-break marks on the inner sheath layer are arranged in a staggered manner with the pre-break marks on the outer sheath layer.

[0018] The working principle of the utility model is as follows: when the adjacent cables 9 need to be connected in terms of the conductor, the outer sheath is cut along the pre-break mark on the side surface, then a part of the flame-retardant layer and the waterproof layer are circumferentially cut, then the inner sheath is cut along the pre-break mark, at this time, the insulation layer and the conductor are exposed, then the conductor is connected, then the inner sheath is reset, the protective sleeve is arranged, then the outer sheath is reset again, and the cable connection is completed. Preferably, another protective structure can be additionally arranged outside the outer sheath connection position.

[0019] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
