[0026] Please refer to Figures 1-4 The present application provides an embodiment of an anti-animal-biting optical-electric composite cable. The present application mainly aims to improve the problems of the existing cable, such as easy to be bitten off by animals, low safety, easy to cause network and signal interruption, and great hidden dangers to military and national defense construction, society and personal property. The specific solutions are as follows:

[0027] The anti-animal-biting optical-electric composite cable comprises an inner sheath 2, a plurality of cable cores 1 wrapped inside the inner sheath 2, a fiber paste provided between the inner sheath 2 and the cable core 1, an insulating sleeve 11, an elastic sleeve 3, a guide sleeve 4 and an outer sheath 8 provided outside the inner sheath 2 from inside to outside, wherein the inner side surface of the insulating sleeve 11 is attached to the outer side surface of the inner sheath 2, and the outer side surface of the insulating sleeve 11 is attached to the inner side surface of the elastic sleeve 3. A gas collecting cavity 6 is provided between the guide sleeve 4 and the elastic sleeve 3, and a filling material of insect repellent drug is filled in the gas collecting cavity 6. The insect repellent drug can drive animals away by emitting a smell, and the smell emitted by the insect repellent drug is automatically released during the biting process of the animals, so that the animals can quickly move away, and the service life of the optical-electric composite cable can be effectively guaranteed.

[0028] Please refer to Figure 1 and Figure 3 The outer sheath 8 comprises an axial adhesive strip 81 and a longitudinal adhesive strip 82. The axial adhesive strip 81 is arranged inside the longitudinal adhesive strip 82, and the axial adhesive strip 81 and the longitudinal adhesive strip 82 are perpendicular to each other. The axial adhesive strip 81 and the longitudinal adhesive strip 82 are connected by gluing. The distance between adjacent longitudinal adhesive strips 82 is 1-2 mm. By using the lap joint mode of the axial adhesive strip 81 and the longitudinal adhesive strip 82, the support strength of the optical-electric composite cable can be improved, and the ability to withstand transverse and longitudinal pulling forces can be improved. Specifically, the longitudinal adhesive strips 82 are arranged at equal intervals outside the axial adhesive strip 81, and a distance is provided between adjacent longitudinal adhesive strips 82.

[0029] Please refer to Figure 2In the outside of the sheath 8 is glued with flexible ring 7, wherein, the flexible ring 7 elastic sleeve 3 and flexible ring 7 between the set of deflation mechanism 5, deflation mechanism 5 includes swing plate 51, wherein, swing plate 51 material is made of polyethylene material, single swing plate 51 is arc-shaped, and swing plate 51 outside and inside of the flexible ring 7 contact. Swing plate 51 is evenly and equidistantly arranged in the inside of the flexible ring 7, and the hardness thereof can enhance the strength of the optical fiber composite cable. Wherein, swing plate 51 is fixed on the outer sheath 8 through the support rod 9, swing plate 51 is movably sleeved on the support rod 9, wherein, the support rod 9 is made of flexible rubber. The gas guide rod 52 is inserted at both ends of the swing plate 51, and the center line of the gas guide rod 52 is parallel to the center line of the support rod 9. When the gas guide rod 52 at one end of the swing plate 51 provides pressure from outside to inside, like seesaw principle, at this time, the gas guide rod 52 at the other end of the swing plate 51 is pulled upward; similarly, the opposite. Wherein, the gas guide rod 52 is movably inserted in the outer sheath 8, the flexible ring 7 and the guide sleeve 4, and the lower end of the gas guide rod 52 is arranged in the inside of the guide sleeve 4.

[0030] The trigger boss 53 is arranged at the outer end of the gas guide rod 52, the outer side of the trigger boss 53 is arc-shaped, and the material of the trigger boss 53 is cowhide material, which has certain tear resistance. And the trigger boss 53 is arranged on the outside of the outer sheath 8, the inner cavity of the gas guide rod 52 is provided with a gas inlet hole 54, and the gas inlet hole 54 is communicated with the exhaust hole 55 at the opposite end of the trigger boss 53, wherein, the upper end of the gas inlet hole 54 is communicated with the exhaust hole 55, the lower end is open, and is in the shape of inwardly recessed cone.

[0031] The anti-extrusion member 10 is arranged between the adjacent gas guide rods 52, and the adjacent gas guide rods 52 are guided and positioned by the guide sleeve 4, and the anti-extrusion member 10 is arranged between the adjacent gas guide rods 52.

[0032] The support rod 9 is arranged on the middle part of the anti-extrusion part 10. The support rod 9 is arranged between the adjacent air guide rods 52, and the support rod 9 is arranged to fix the swing plate 51. The elastic boss 12 is arranged on the outer side of the elastic sleeve 3 and corresponds to the inner and outer sides of the air guide rod 52. The elastic boss 12 corresponds to the inner and outer positions of the air guide rod 52, and the outer end of the elastic boss 12 is provided with a protruding tapered tip. The air guide rod 52 is provided with a protruding tapered tip on the opposite end of the elastic boss 12. The elastic boss 12 is arranged in the gas collecting cavity 6. The outer end of the elastic boss 12 is movably inserted into the air guide rod 52. In the initial state, the protruding tapered tip on the outer side of the elastic boss 12 can block the lower end of the gas inlet hole 54 arranged in the air guide rod 52 by the elastic effect of the elastic boss 12, effectively preventing the odor in the gas collecting cavity 6 from being emitted to the outside. When the air guide rod 52 at one end of the swing plate 51 is swung by the acting force, the air guide rod 52 at the other end of the swing plate 51 is provided with a downward pushing force. At this time, the distance between the elastic boss 12 and the outer sheath 8 is increased, and the exhaust hole 55 on the air guide rod 52 pushed out of the outer sheath 8 leaks out of the outer sheath 8 by the pushing action. At this time, the odor emitted in the gas collecting cavity 6 enters the exhaust hole 55 through the gas inlet hole 54 and is discharged to the outside. At this time, the gas is automatically released in the process of the animal biting the photoelectric composite cable, so that the animal loosens the large mouth of tearing and bites and quickly moves away from the photoelectric composite cable. In the initial state, the odor will not be released in large quantities to the outside, but only a small amount of odor will be released at the contact position of the outer sheath 8 and the air guide rod 52, which can not only increase the service life of the insect repellent drug filling material in the photoelectric composite cable, but also save unnecessary waste. Some animals can be avoided from biting by releasing a certain amount of odor. When some animals are not sensitive to the released small amount of odor, a large amount of odor can be automatically released by the biting of the animal to drive away the animal and move away from the photoelectric composite cable.

[0033] Working principle: In the use of the animal-biting-resistant photoelectric composite cable, in the initial state, the odor will not be released in large quantities to the outside, but only a small amount of odor will be released at the contact position of the outer sheath 8 and the air guide rod 52, which can drive some animals. When some animals are not sensitive to the released small amount of odor, the biting of the animal can make the trigger boss 53 at the bitten position swing the air guide rod 52 at one end of the swing plate 51 by the acting force, so that the air guide rod 52 at the other end of the swing plate 51 is provided with a downward pushing force. At this time, the distance between the elastic boss 12 and the outer sheath 8 is increased, and the exhaust hole 55 on the air guide rod 52 pushed out of the outer sheath 8 leaks out of the outer sheath 8 by the pushing action. At this time, the odor emitted in the gas collecting cavity 6 enters the exhaust hole 55 through the gas inlet hole 54 and is discharged to the outside. At this time, the gas is automatically released in the process of the animal biting the photoelectric composite cable, so that the animal loosens the large mouth of tearing and bites and quickly moves away from the photoelectric composite cable.
