[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, a rodent-proof, cold-resistant, and flame-retardant wire includes a wire 1 with a core 15, a protective strip 2 arranged in a circle on the outside of the core 15, and a connecting strip 3 assembled between adjacent protective strips 2.

[0030] Multiple spikes 21 are provided on the side wall of the protective strip 2;

[0031] The connecting strip 3 fits between the two protective strips 2 to form a retention recess 20;

[0032] After assembly, a hybrid layer 13 is provided on the outside of the protective strip 2 and the connecting strip 3.

[0033] Specifically, the battery core 15 is located on the innermost side of the wire 1, and a rubber strip is wrapped around the outside of the battery core 15 to protect the conductive metal wire. The protective strip 2 is a deformable elastic metal strip, which is armored on the outside of the battery core 15 during the production of the wire 1. The tip of the spike 21 is sharpened.

[0034] Furthermore, the retention depressions 20 are arranged in a spiral shape, and the mixed layer 13 is made of a combination of glass fiber, silicone rubber and aluminum and iron metal particles.

[0035] By assembling multiple connecting strips 3 inside the protective strip 2, a complete ring is formed to protect the inner battery cell 15, preventing biological corrosion from penetrating the ring and damaging the battery cell 15. Simultaneously, the multiple spikes 21 on the protective strip 2 point outwards to prevent rodents from biting. The hybrid layer 13 outside the spikes 21 uses glass fibers and metal particles to injure rodents, thus reducing the corrosive damage caused by rodents to the wire 1 and ensuring the operational safety of the wire 1. When the hybrid layer 13 is severely damaged, the corrosive liquid expelled by organisms is blocked by the retention depression 20, ensuring the safety of the ring's interior. Furthermore, some of the corrosive liquid will affect antagonistic organisms due to the food chain, thus giving the wire 1 a biological protection function.

[0036] As a further embodiment of this utility model, the inner wall of the protective strip 2 is provided with symmetrically arranged locking holes 22, and the outer wall of the connecting strip 3 is fixedly installed with a protruding strip 31 that fits into the locking holes 22.

[0037] By first wrapping the connecting strip 3 around the protective strip 2 and then wrapping and snapping it onto the protruding strip 31, the entire ring can have excellent pressure and torsion resistance, while also increasing the snapping sealing area and making the connection between the two more stable.

[0038] As another embodiment further provided by this utility model, a notch 30 communicating with the retention recess 20 is provided between the two protrusions 31.

[0039] The gap 30 is used to store the biological corrosive liquid collected by the retention depression 20, thereby increasing the collection and storage capacity of the corrosive liquid (increasing storage capacity) and realizing the efficient utilization of the corrosive liquid.

[0040] As another embodiment further provided in this utility model, a retention chamber 33 is provided in the protrusion 31.

[0041] The snap-fit ​​combination of the protrusion 31 and the snap-fit ​​hole 22 makes it difficult for the corrosive liquid collected in the notch 30 to climb and invade, thus ensuring the environment inside the ring. The retention chamber 33 can be retained before the climbing path, so that the corrosive liquid is stably stored in the retention chamber 33 and prevents it from continuing to invade the interior.

[0042] As another embodiment provided in this utility model, a through hole 32 for connecting the retention chamber 33 and the notch 30 is provided on one side of the protrusion 31.

[0043] The through-hole 32 makes it easier for liquid to enter the retention chamber 33, thus allowing the liquid to be preferentially transported by the through-hole 32, making it less likely for the liquid to enter through the snap-fit ​​position.

[0044] As another embodiment of this utility model, the outer side of the battery cell 15 is provided with an inner rubber layer 14 that cooperates with the connecting strip 3.

[0045] The inner rubber layer 14, composed of polytetrafluoroethylene, ethylene propylene rubber and chloroprene rubber, provides corrosion protection for the battery cell 15, further enhancing its protection capabilities.

[0046] As another embodiment provided in this utility model, a flame-retardant layer 12 is provided on the outer side of the hybrid layer 13.

[0047] The flame-retardant layer 12, composed of mica tape and cross-linked polyethylene, enables the wire 1 to have basic fire-resistant and flame-retardant capabilities.

[0048] As another embodiment provided in this utility model, a protective layer 11 is provided on the outside of the flame retardant layer 12.

[0049] The protective layer 11, made of silicone rubber, enables it to have high flexibility, pressure resistance, and high temperature resistance.

[0050] As another embodiment further provided in this utility model, the spike 21 is specifically a steel spike.

[0051] The use of steel makes spike 21 more corrosion resistant, keeping it in excellent condition to resist rodent gnawing.

[0052] As another embodiment further provided in this utility model, the connecting strip 3 is specifically an elastic metal sheet.

[0053] The flexible metal sheet allows the connecting strip 3 to deform more easily along with the protective strip 2, thus ensuring the wire 1's resistance to pressure and bending.

[0054] Working principle: By assembling multiple connecting strips 3 inside the protective strip 2, a complete ring is formed to protect the inner battery cell 15, preventing biological corrosion from penetrating the ring and damaging the battery cell 15. Simultaneously, the multiple spikes 21 on the protective strip 2 point outwards to prevent rodents from biting. The hybrid layer 13 outside the spikes 21 uses glass fibers and metal particles to injure rodents, thus reducing the corrosive damage to the wire 1 caused by rodents. When the hybrid layer 13 is severely damaged, the corrosive liquid excreted by organisms is blocked by the retention depression 20, ensuring the safety of the ring's interior. Furthermore, some of the corrosive liquid will affect antagonistic organisms due to the food chain.

[0055] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
