The entire outside is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside.

[0003] For example, a segmented cable that is easy to combine and splice is disclosed with announcement number CN212182667U, including a cable body, wherein placement rings are symmetrically installed on the outer side of the cable body, a first connector is connected to one end of the cable body at a position corresponding to one side of one of the placement rings, and a second connector is connected to one end of the cable body at a position corresponding to one side of the other placement ring. Through the provision of the first connector, the second connector, the placement ring, the connecting buckle and the connecting buckle groove, the connecting buckle and the connecting buckle groove can be adsorbed and connected, which is convenient for rapid installation between the two cable bodies and assembly and splicing between the cable bodies.
