Special connecting line for power bank

The utility model discloses a special connecting line for a power bank, which comprises a sheath and a wrapping tape from outside to inside, a cavity is formed in the wrapping tape, a plurality of strands of conductors are arranged in the cavity, the outer surfaces of the conductors are wrapped with insulating layers, and each pair of conductors are separated by filling materials and are arranged around the inner circumference of the cavity; and a groove body arranged along the length of the cable is also arranged in the sheath. By changing the wire core structure, the outer diameter of the wire rod is reduced, the manufacturing cost is reduced, and the charging power and the tensile and bending performance are improved. According to the cable, the arc-shaped groove bodies are designed in the sheath, the arc-shaped groove bodies are parallel to one another and are arranged in the sheath at intervals, and by means of the arc-shaped groove bodies, the situation that the cable cannot be well bent due to the fact
