[0038] Working principle: when installing the cable body 8, the cable body 8 is placed in the inner wall of the heat dissipation layer 5, then the heat dissipation layer 5 with the heat fins 6 is placed on the inner side of the protective layer 4, after assembly, the two sets of connecting plates 2 and the arc-shaped plate 3 are placed on the outer wall of the protective layer 4, at this time the limiting column 101 is inserted into the inner wall of the two sets of connecting plates 2, then the limiting rod 103 is manually rotated, so that the limiting rod 103 drives the limiting column 101 to rotate in the inner wall of the sliding plate 102, at this time the steel ball 107 in the inner wall of the circular groove three 104 is in contact with the inner wall of the connecting plate 2, so that the steel ball 107 is pressed by the inner wall of the connecting plate 2 on both sides, at this time the elastic element 106 is compressed into the inner wall of the limiting column 101, the limiting column 101 is continuously rotated, when the circular groove three 104 is rotated to the position where it is flush with the circular groove two 10, at this time the inner wall of the connecting plate 2 on both sides no longer presses the steel ball 107, at this time the elastic element 106 restores elasticity and drives the steel ball 107 into the inner wall of the circular groove two 10, at this time the limiting column 101 is fixed in the inner wall of the circular groove one 9 of the protective layer 4, so that the cable body 8 can be fixed at the cable terminal, thereby avoiding falling during use, and enabling the cable to start transmitting power, during power transmission, due to high load flow, the cable body 8 generates heat, since the inner wall of the heat fin 6 is fixed with the outer wall of the cable body 8, and the heat fin 6 made of aluminum alloy has good heat conductivity, the heat generated by the cable body 8 can be rapidly conducted to the heat fin 6, the heat fin 6 conducts the heat to the heat dissipation layer 5 in contact with it, the heat dissipation layer 5 also has certain heat conduction capacity and can receive and further transmit heat, dissipate heat through the heat dissipation holes 7, increase the heat dissipation area through the heat dissipation holes 7, enable the heat to dissipate from the heat dissipation holes 7 to the surrounding environment in the form of heat convection and heat radiation, although the surrounding environment is closed, the heat dissipation holes 7 provide a channel for heat dissipation, so that the heat can be transmitted from the surface of the protective layer 4 to the air in the closed space, and then slowly dissipate heat to a farther place through the flow of air, thereby reducing the temperature of the cable and ensuring the normal operation of the cable.

[0039] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still falls within the protection scope of the technical scheme of the present application.
