Each connection rib group has at least two connection ribs distributed at intervals in the circumferential direction. Each connection rib is connected between the inner wall of the tubular body and the tubular body in the radial direction, thereby forming a containing area between any two connection ribs arranged adjacent in the circumferential direction. One optical fiber core or conductor core is arranged in each containing area. A plurality of reinforcing core wires extending along the axial direction are embedded in the tubular body, and the reinforcing core wires are distributed at equal intervals in the circumferential direction.
[0005] The further improved scheme in the above technical solution is as follows:

[0009] 5. The scheme, the conductor core includes: a plurality of mutually twisted copper wires, the inner shielding layer arranged outside the copper wire and the second insulating layer arranged outside the inner shielding layer.
[0010] Due to the use of the above technical scheme, the utility model has the following advantages compared with the prior art:
