Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a rat-proof cable. Background Art

[0002] Rat-proof cables are relatively common cables. The existing technology uses overlapping fireproof ribbons made of glass ribbons to effectively improve the cable's anti-rat and ant performance. Its fundamental protection measure is physical protection, which improves the strength of the cable to prevent rats from biting and damaging the inner layer of the cable. However, the existing technology does not have the function of warning the cable when it is broken after being bitten by rats. It is more troublesome for personnel to maintain the cable in the later stage, which increases the burden on personnel to maintain the cable. Personnel need to observe and maintain the cable regularly, and people have conducted a lot of research on this. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 6 As shown, the utility model is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are Figure 1 The projection relationship of the utility model is consistent with the up-down, left-right, front-back directions. The utility model is a rat-proof cable, including a cable protective layer 41, and first clamps 14 are arranged at both ends of the outer surface of the cable protective layer 41. The outer side of the first clamp 14 is sleeved with a second clamp 13. It is characterized in that a wire 21 is arranged between the first clamps 14 on both sides and between the second clamps 13 on both sides. A first connecting wire 19 is arranged in the first clamp 14 on one side, and a second connecting wire 22 is arranged in the first clamp 14 on the other side. The first connecting wire 19 and the second connecting wire 22 are respectively connected to the first clamp 1 The two ends of the wire 21 at both ends are electrically connected, wherein the third connecting wire 12 is arranged in the second clamp ring 13 on one side, and the fourth connecting wire 23 is arranged in the second clamp ring 13 on the other side, the third connecting wire 12 and the fourth connecting wire 23 are electrically connected to the two ends of the wire 21 between the second clamp ring 13 respectively, and the wire 21 inserted back and forth forms an end connecting wire 18 on the side of the second clamp ring 13 and the first clamp ring 14, and the electrodes are connected to the positive and negative electrodes of the power supply respectively by connecting the electrodes on the side of the first connecting wire 19 and the third connecting wire 12, and connecting the electrodes on the side of the second connecting wire 22 and the fourth connecting wire 23.

[0024] Advantageously, a first series circuit is formed by the first connecting wire 19, a third connecting wire 12 and a conducting wire 21, and a second series circuit is formed by the conducting wire 21, a second connecting wire 22 and a fourth connecting wire 23. A light-emitting diode can be connected to one side of the electrode. After the conducting wire 21 is damaged, the light-emitting diode goes out, indicating that the conducting wire 21 on the surface of the cable protective layer 41 is bitten through. Personnel can detect whether the cable protective layer 41 is bitten through and damaged as soon as possible after discovering it. Since the conducting wires 21 on one side of the first clamp ring 14 and the second clamp ring 13 are respectively connected to a power source and a light-emitting diode, it can be determined whether the conducting wires 21 on both sides are bitten through based on the light-off situation. If the light-emitting diodes connected to the conducting wires 21 on both sides are off, the probability of the cable protective layer 41 being damaged is relatively high.

[0025] Advantageously, a connecting wire 11 can be connected between the third connecting wire 12 and the first connecting wire 19, and a series circuit is formed by the connecting wire 11, the first connecting wire 19, the third connecting wire 12, the conductor 21, the second connecting wire 22 and the fourth connecting wire 23 to electrically connect the third connecting wire 12 and the first connecting wire 19. At this time, the electrodes on one side of the conductor 21 and the second connecting wire 22 need to be connected to the positive and negative poles of the power supply. As long as one of the conductors 21 is damaged and disconnected, the light-emitting diode can be turned off.

[0026] Advantageously, a plurality of cables 16 are arranged in the cable protective layer 41, a bracket 17 is sleeved on the outer surface of the cable 16, a plurality of connecting blocks 15 are fixedly arranged on the outer surface of the bracket 17, the connecting blocks 15 and the bracket 17 form a circular bracket to support the inside of the wire 21, a plurality of threaded columns 31 are arranged on the outer surface of the bracket 17, the threaded columns 31 pass through the first clamping ring 14 and the second clamping ring 13, a nut 32 is arranged on the outer surface of the threaded column 31 in threaded cooperation, and the nut 32 is arranged against the second clamping ring 13.

[0027] The cable uses wires 21 that are inserted back and forth and are arranged between the second clamp ring 13 and the first clamp ring 14, so that the light emitting diode of one of the wires 21 will go out after being damaged and disconnected. Personnel can know the damage of the wire 21 in time and can comprehensively judge whether the cable protective layer 41 is damaged.

[0028] When the cable is manufactured, the bracket 17 and the connecting block 15 are pre-arranged on the outer surface of the cable line 16 and located in the cable protective layer 41. First, the first clamping ring 14 and the second clamping ring 13 are plugged and fixed through the threaded column 31, and the nut 32 is threadedly connected with the threaded column 31 to make the second clamping ring 13 and the first clamping ring 14 stably sleeved on the outer surface of the cable protective layer 41.

[0029] A conductive wire 21 is inserted between the first clamping rings 14 on both sides and between the second clamping rings 13, so that a first connecting wire 19 is set on one side of the first clamping ring 14, and a second connecting wire 22 is set on the other side of the first clamping ring 14, a third connecting wire 12 is set on one side of the second clamping ring 13, and a fourth connecting wire 23 is set on the other side of the second clamping ring 13. The conductive wire 21 is electrically connected to a power source and a light-emitting diode, and the damage condition of the conductive wire 21 is judged according to the condition of the light-emitting diode, so that personnel can estimate the probability of damage to the cable protective layer 41.

[0030] A protective layer may be covered on the outside of the second clamp ring 13 to further protect the wire 21 , and mice can bite the wire 21 only after biting through the protective layer.

[0031] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
