Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, a resistant stretch-proofing cable of buckling for mobile communication, including PVC oversheath 1 and guard plate 2, the inner wall of PVC oversheath 1 closely laminates and has guard plate 2, PVC oversheath 1, the inner wall closely laminate and have go-between 3, the solid fixed ring 301 of the inside fixedly connected with of go-between 3, the inside embedding of solid fixed ring 301 is provided with gasbag ball 302, the inner wall embedding of go-between 3 is provided with inner sheath 4, the inside embedding of inner sheath 4 is provided with filling layer 5, the inside embedding of filling layer 5 is provided with cable core 6.

In this embodiment, protection plate 2 is hugged closely to one side that air bag ball 302 is close to 1 outer wall of PVC oversheath, and inner sheath 4 is hugged closely to one side that air bag ball 302 is close to 4 middle parts of inner sheath for when the protection plate 2 of PVC oversheath 1 is buckling, the air bag ball 302 of extrusion go-between 3 makes air bag ball 302 compress, prevents that the protection plate 2 of PVC oversheath 1 is direct to contact with 4 inner sheaths, and resistance to compression and resistant performance of buckling are better.

In this embodiment, gasbag ball 302 agrees with solid fixed ring 301 of go-between 3 mutually, and the quantity of gasbag ball 302 and solid fixed ring 301 is 11-13, and gasbag ball 302 and solid fixed ring 301 are the ring form setting around the middle part of go-between 3, make when the guard plate 2 of PVC oversheath 1 is buckling, extrude gasbag ball 302 of go-between 3, make gasbag ball 302 compress, and gasbag ball 302 on the go-between 3 can carry out all-round protection to cable core 6, and resistance to compression and resistant bending performance are better.

In the embodiment, the inner sheath 4 is provided with a plurality of groups of connecting rings 3 in an embedded mode, the distance between the connecting rings 3 is 5-8cm, so that when the PVC outer sheath 1 and the protection plate 2 on the outer side of a single cable are bent, the inner wall of the PVC outer sheath can be extruded and moved to the gap between the connecting rings 3, the inner sheath 4 cannot be directly extruded, and the bending resistance is better.

In this embodiment, filling layer 5 is rubber filling layer 5, and filling layer 5 is inside to be hollow latticed setting for when the cable is buckling, 5 compressions of filling layer of inner sheath 4 prevent external force direct extrusion inner sheath 4, resistance to compression and resistant bending property are better.
