[0002] The ratproof aerial cable is a specially designed optical cable, which is designed to prevent rodents and other small animals from damaging the optical cable, and at the same time, it meets the needs of aerial laying, such as preventing rats from climbing along the tower, lead, etc. to the surface of the aerial cable and biting. The optical cable is wrapped with a special material on the outer layer of the optical cable to block the damage caused by the biting of small animals, and at the same time, it usually adopts a material with high mechanical strength, which has high waterproof and flame-retardant properties.

[0003] At present, the ratproof aerial cable mainly selects the structure and material during the manufacturing of the optical cable; on the structure, stainless steel belts and thick steel belts are used to improve the physical ratproof ability of the optical cable, and on the material, nylon and ratproof materials containing spicy microcapsules are selected, so that they are not easy to be damaged, and the sheath material has a rat-repelling odor. Due to the above structure, the cost of the structure and material of the ratproof aerial cable is obviously higher than that of the ordinary optical cable. SUMMARY

[0005] In order to solve the problem that the ratproof aerial cable in the prior art has high cost of structure and material setting to ensure mechanical strength and ratproof performance, a ratproof aerial cable is provided, which adopts a specially set structure to reduce the damage caused by rat biting during later processing and laying, so as to reduce the manufacturing cost of the ratproof aerial cable and reduce rat biting.

[0006] The utility model adopts the technical scheme as follows:

[0007] A ratproof aerial cable, comprising an optical cable sheath, a plurality of barb mechanisms are uniformly and spacedly arranged on the outer surface of the optical cable sheath along the axial direction of the optical cable sheath, and a barb restraint member is arranged on the outer surface of the optical cable sheath and the plurality of barb mechanisms.

[0008] The barb mechanism comprises a fixed member which is attached to the optical cable sheath and fixedly connected, one end of the fixed member is connected with a first barb member, the first barb member is elastically connected with the fixed member, and the barb restraint member is used for elastically restraining the first barb member on the surface of the optical cable sheath.

[0009] Further, one end of the fixed member away from the first barb member is also connected with a second barb member, the second barb member is elastically connected with the fixed member, the second barb member and the first barb member are symmetrically arranged relative to the fixed member, and the barb restraint member is used for elastically restraining the first barb member and the second barb member on the surface of the optical cable sheath.

[0010] Further, the barb mechanism is composed of metal steel material or hard plastic.

[0011] Further, the fixing member and the optical cable jacket are connected by adhesive connection, thermal bonding connection or injection molding connection.

[0012] Further, the interval distance of the barb mechanism is set to 100-1500mm.

[0013] Further, the outer surface of the optical cable jacket is further coated with a nylon outer sheath, and the barb mechanism is arranged on the surface of the nylon outer sheath.

[0014] As described above, due to the adoption of the above technical scheme, the beneficial effects of the present application are:

[0015] The barb mechanism is arranged on the optical cable jacket to prevent rodents and other animals from biting. Compared with the structure of high-strength stainless steel belt and thick steel belt, the cost of the barb mechanism is lower. The fixing member and the barb member on the barb mechanism are elastically connected, and the barb member is covered inside by the barb restraint member arranged outside before laying. The barb member can be automatically unfolded along the surface of the optical cable jacket at a certain inclination angle to form uniformly spaced barbs, thereby achieving the function of preventing rodents. The overhead optical cable of the structure reduces the related cost in production, transportation, storage, laying and use, and is more convenient for transportation, storage and laying.
