[0030] Example 1

[0031] Combined with Figure 1 This embodiment provides an intelligent anti-theft warning return single-core cable, including:

[0032] Conductor assembly;

[0033] A plurality of optical fibers 4 are spaced apart and sleeved outside the conductor assembly;

[0034] A plurality of tensile support filling strips 5 are sleeved outside the conductor assembly at intervals;

[0035] A sheath assembly sleeved on a plurality of optical fibers 4 and a plurality of tensile support filler strips 5;

[0036] The number of tensile support filling strips 5 is greater than the number of optical fibers 4 .

[0037] Specifically, the conductor component is used to transmit signals; when the optical fibers 4 detect that the external environment applies pressure, the pressure signal will be transmitted to the control terminal, and the control terminal will sound an alarm. After receiving the alarm, the monitoring personnel can prevent and stop theft, thereby preventing the intelligent anti-theft warning return single-core cable from being stolen, and has good intelligent anti-theft warning performance; since the optical fibers 4 and the tensile support filling strips 5 are arranged at intervals, and since the number of tensile support filling strips 5 is greater than the number of optical fibers 4, it is convenient for the tensile support filling strips 5 to be mainly used for tension and support (i.e., compression), thereby preventing the optical fibers 4 from being tensioned and supported, and thus making the optical fibers 4 less susceptible to damage; the sheath component is used to protect the optical fibers 4, the tensile support filling strips 5, etc., wherein the specific number of the tensile support filling strips 5 is not limited, preferably nine, and the specific number of the optical fibers 4 is not limited, preferably three.

[0038] Furthermore, there are at least two tensile support filling strips 5 between adjacent optical fibers 4 .

[0039] Specifically, at least two tensile support filling strips 5 are provided to facilitate tensile resistance and support for adjacent optical fibers 4 , and preferably three tensile support filling strips 5 are provided between adjacent optical fibers 4 .

[0040] Furthermore, the number of tensile support filling strips 5 between adjacent optical fibers 4 is equal.

[0041] Specifically, an equal number of tensile support filling strips 5 facilitates uniformity of tensile strength and support between adjacent optical fibers 4 .

[0042] Furthermore, a plurality of optical fibers 4 and a plurality of tensile support filling strips 5 are evenly spaced along the circumference of the conductor assembly.

[0043] Specifically, the uniform circumferential spacing makes it easier to ensure that the tensile strength and support uniformity of the intelligent anti-theft warning return single-core cable are good.

[0044] Furthermore, the tensile support filling strip 5 comprises:

[0045] Steel wire 51;

[0046] A polypropylene layer 52 sleeved on the outside of the steel wire 51;

[0047] The polypropylene layer 52 is sleeved on the outside of the conductor component at intervals, the sheath component is sleeved on the outside of the polypropylene layer 52 , and the number of steel wires 51 and the polypropylene layer 52 is greater than the number of optical fibers 4 .

[0048] Specifically, the steel wire 51 is used to make the tensile support filling strip 5 have good tensile performance; the polypropylene layer 52 is used to make the tensile support filling strip 5 have good supporting and filling performance.

[0049] Further, the conductor assembly comprises:

[0050] Conductor body 1;

[0051] An insulating layer 2 sleeved on the conductor body 1;

[0052] Among them, a plurality of optical fibers 4 and a plurality of tensile support filling strips 5 are sleeved outside the insulating layer 2 at intervals.

[0053] Specifically, the conductor body 1 is used to transmit signals, and the material of the conductor body 1 can be copper, aluminum, etc.; the insulating layer 2 is used for insulation, and the material of the insulating layer 2 can be polyethylene, polyvinyl chloride, etc.

[0054] Furthermore, the conductor assembly also includes a first water-blocking tape 31 and a second water-blocking tape 32 which are sequentially sleeved on the outside of the insulating layer 2 , and a plurality of optical fibers 4 and a plurality of tensile support filling strips 5 are sleeved on the second water-blocking tape 32 at intervals.

[0055] Specifically, the first water-blocking tape 31 and the second water-blocking tape 32 are used to block water and prevent the optical fibers 4 and the tensile support filling strips 5 from damaging the insulating layer 2. The first water-blocking tape 31 and the second water-blocking tape 32 are preferably made of a composite of polyester fiber woven cloth and highly water-absorbent material.

[0056] Furthermore, the sheath assembly includes a water-blocking layer 6 and an outer sheath 7 which are sequentially sleeved on the outside of a plurality of optical fibers 4 and a plurality of tensile support filling strips 5 .

[0057] Specifically, the water-blocking layer 6 is used for water blocking, and the water-blocking layer 6 is preferably made of a composite of polyester fiber woven cloth and a highly absorbent material; the outer sheath 7 is used for protection, and the material of the outer sheath 7 can be polyethylene, polyvinyl chloride, etc.

[0058] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
