Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a top view of the optical fiber slot filling block of the present invention;
fig. 3 is a top view of the optical fiber groove of the present invention.
Detailed Description
As shown in fig. 1, a cable convenient for replacing optical fibers comprises a cable body, a plurality of optical fiber grooves 1 are arranged on the periphery of the cable body, and an optical fiber groove filling block 2 matched with the optical fiber grooves 1 is further included;
the optical fiber groove 1 and the optical fiber groove filling block 2 are both of a water-drop-shaped structure with a narrow outer end and a large inner end, a U-shaped groove 3 with a downward opening is formed in the bottom of the optical fiber groove filling block 2, a base 4 is arranged at the bottom of the optical fiber groove 1, and an arc-shaped groove 5 is formed in the upper end of the base 4;
the U-shaped groove 3 and the arc-shaped groove 5 enclose a circular optical fiber placing cavity 6 for placing optical fibers. The optical fiber can be effectively protected by being placed in the optical fiber placing cavity 6.
Preferably, a U-shaped pipe 7 is arranged on the inner side of the U-shaped groove 3, and an arc-shaped pipe 8 is arranged on the inner side of the arc-shaped groove 5.
Preferably, the U-shaped pipe 7 and the arc-shaped pipe 8 are both metal pipes. The metal tube has a protection effect on the optical fiber, the optical fiber can be well protected in the process of bending and drawing the cable, and the metal layer can have a shielding effect.
Preferably, as shown in fig. 2-3, a plurality of stop bars 9 are uniformly arranged on both sides of the optical fiber groove filling block 2, and stop grooves 10 matched with the stop bars 9 are arranged on both sides of the optical fiber groove 1. The optical fiber groove filling block 2 is prevented from displacing in the optical fiber groove 1 during the bending or drawing process of the cable.
Preferably, the cable body sequentially comprises a conductor 11, a metal shielding layer 12, an insulating layer 13 and an optical fiber setting layer 14 from inside to outside, and the optical fiber groove 1 is arranged in the optical fiber setting layer 14.
