Being coated on the outside of optical fiber, described optical fiber is multicore structure, is additionally provided with adding of being coaxial therewith on the central axis of armor
Strong part；Buffer strip, the cross section of described buffer strip it is additionally provided with between lateral wall and the medial wall of oversheath of described armor
The wavy shaped configuration disconnected for two ends, the crest of described wavy shaped configuration contacts with the medial wall of oversheath, and described waveform is tied
The trough of structure contacts with the lateral wall of armor.
Further, it is additionally provided with gasket for packing in described armor.
Further, the gap between inner chamber and conductive unit, fiber unit, reinforcement, the gasket for packing of armor is filled
There is cable layer of paste.
Further, described buffer strip is galvanized steel strip.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but protection domain of the present utility model is not limited to
The following stated.
As it is shown in figure 1, optical fiber composite low-voltage cable, including oversheath 1, conductive unit, fiber unit and reinforcement 8, institute
Stating the cylinder tubular structure that oversheath 1 is hollow, be provided with armor 2 inside oversheath 1, armor 2 is same with oversheath 1
Axle, described conductive unit and described fiber unit are arranged in armor 2, and described conductive unit includes conductor jacket 3 and conductor
4, conductor jacket 3 is coated on the outside of conductor 4, and described fiber unit includes screen layer 5 and optical fiber 6, and screen layer 5 is coated on optical fiber
The outside of 6, described optical fiber is multicore structure, is additionally provided with the reinforcement 8 being coaxial therewith on the central axis of armor 2；Institute
Stating and be additionally provided with buffer strip 9 between the lateral wall of armor 2 and the medial wall of oversheath 1, the cross section of described buffer strip 9 is two
The wavy shaped configuration that end disconnects, the crest of described wavy shaped configuration contacts with the medial wall of oversheath 1, described wavy shaped configuration
Trough contacts with the lateral wall of armor 2, and when buffer strip 9 stress produces deformation, buffer strip 9 stretches to two ends, due to buffering
Two ends with 9 disconnect, and i.e. have hatch frame, and after being squeezed, the two ends of buffer strip 9 are close to each other, and simultaneous buffering band 9 has again
Certain toughness, produces counteracting force to external force, thus plays resistance to compression effect, and this is conducive to optical fiber composite low-voltage cable at environment relatively
