Specific embodiment

As shown in Figs 1-4, Fig. 1 be the utility model proposes a kind of heavy mobile service photoelectric compound cable section view Figure, Fig. 2 be tension core wire and tensile ring structural schematic diagram, Fig. 3 be the utility model proposes a kind of heavy mobile service use The structural schematic diagram of photoelectric compound cable, Fig. 4 be the utility model proposes a kind of heavy mobile service photoelectric compound cable Structural schematic diagram.

Referring to Fig.1, the utility model proposes a kind of heavy mobile service photoelectric compound cable, the cable is from introversive It outside include optical fiber cable core 1, the first sheath 2, the second sheath 3, more power wire cores 4 and outer jacket 5；Optical fibre core is for passing Transmission of data, power wire core 4 are used for transmission electric power；

Prepsetting gap between optical fiber cable core 1 and the first sheath 2 is equipped with rubber skeleton 6, rubber skeleton 6 in the gap Including three rubber strips, rubber strip is connect with optical fiber cable core 1 and the first sheath 2, and more rubber strips are circumferential along optical fiber cable core 1 Optical fibre core is supported in the first sheath 2 by even setting, three rubber strips；

Prepsetting gap between first sheath 2 and the second sheath 3, when cable folding, shield in the first sheath 2 and second Layer 3 opposite can slide, and improve the flexibility of cable entirety.

The heavy mobile service photoelectric compound cable that the present embodiment proposes, it is pre- between optical fibre core and the first sheath 2 If gap, when cable folding, gap provides for optical fibre core and makes a concession space, to avoid core wire bending angle excessive to optical fiber Core wire causes to damage, while being supported optical fibre core by rubber skeleton 6, and optical fibre core and the first sheath 2 is avoided to send out Raw friction causes optical fibre core to damage, and the first sheath 2 and the second sheath 3 opposite can slide, and it is whole to improve cable Flexibility.

In order to improve the opposite sliding ability between the first sheath 2 and the second sheath 3, the first sheath 2 and second Lubricating oil is filled between sheath 3, lubricating oil can be improved the opposite sliding ability of the first sheath 2 and the second sheath 3.
