Embodiment 1

[0029] like Figure 1 to Figure 4As shown, a communication cable with self-healing function according to the embodiment of the present invention includes a cable body 1; a set of cable cores 2 is arranged inside the cable body 1; the outer side of the cable core 2 is wrapped with an insulating layer 3 ; The outer side of the cable body 1 is provided with a sheath 4; the outer surface of the cable body 1 is evenly distributed with a group of No. 1 expansion bars 5, and the No. One end of the strip 5 close to the sheath 4 is provided with a flexible block 6; the outer side of the communication cable body 1 in the prior art is generally provided with a sheath 4 to protect the cable body 1 and improve the waterproof effect of the cable body 1, but The existing sheath 4 does not have the function of self-repair. When the sheath 4 is damaged, the waterproof effect of the cable body 1 will be greatly reduced; at this time, when the communication cable in the present invention is used...

Embodiment 2

[0038] like Figure 5 As shown in the comparison example 1, another embodiment of the present invention is: a side of the No. 1 expansion bar 5 close to the flexible block 6 is provided with a mounting groove 19; the flexible block 6 and the blind end of the mounting groove 19 There is a connecting rope 20 fixed between them, and the connecting rope 20 can be pulled and broken; as the desiccant removes water from the inside of the cell 10, the No. 1 expansion strip 5 will gradually dry and shrink, because the flexible block 6 has been bonded at this time. Inside the sheath 4, if the No. 1 expansion strip 5 is fixed to the flexible block 6, the contraction of the No. 1 expansion strip 5 will reduce the distance between the sheath 4 and the cable body 1, so that the spring 8 is permanently compressed and loses its The buffer function, at this time, the No. 1 expansion bar 5 and the flexible block 6 are connected by the connecting rope 20, and the No. 1 expansion bar 5 is separat...

Abstract

The invention belongs to the technical field of cables, and particularly relates to a communication cable with a self-repairing function, which comprises a cable body, a group of cable cores are arranged in the cable body; the outer side of the cable core is wrapped with an insulating layer; the outer side of the cable body is sleeved with a sheath. A group of first expansion strips are uniformly distributed on the circumference of the outer side surface of the cable body, and the first expansion strips are made of a water-absorbing expansion material; a flexible block is arranged at the end, close to the sheath, of the first expansion strip. When the communication cable is used in water, if a certain position of the sheath is damaged and cracks occur, external water enters the sheath through the cracks, then the first expansion strip at the position expands and extends after absorbing water, the flexible block is pushed to gradually get close to the inner side of the sheath, and the cracks are blocked; and external water cannot continuously flow into the sheath through the crack, so that the waterproof effect of the communication cable is improved, and the communication cable has a certain self-repairing function.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a communication cable with self-healing function. Background technique [0002] A communication cable is a cable that transmits telephones, telegrams, fax files, television and radio programs, data and other electrical signals, and consists of more than one pair of mutually insulated conductors twisted. [0003] A Chinese patent with publication number CN112103005B discloses a communication cable, including a body, a moving cavity is arranged in the body, and a cable that penetrates the body from left to right and is slidably connected to the body is arranged in the body, so The moving cavity is provided with a moving mechanism, the right inner wall of the moving cavity is provided with a cut-off cavity, the cut-off cavity is provided with a cut-off protection mechanism, and the right end face of the body is provided with two limit cavities that open to the right , the limiting c...
