Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, specifically a concave armored flame-retardant and rodent-proof miniature optical cable. Background Technology

[0002] Currently, the main type of optical cable introduced is the butterfly-shaped optical cable, which is widely used in various residential communities.

[0003] However, in older residential areas, poor sanitation and a large number of rats often lead to fiber optic cables being chewed up, posing a significant challenge to communication security and maintenance.

[0004] In addition, although the cross-section of the butterfly-shaped optical cable is small, the insufficient space reserved for the duct in old residential areas increases the difficulty of the cable pulling operation. Therefore, a concave armored flame-retardant and rodent-proof miniature optical cable is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: a concave armored flame-retardant and rodent-proof miniature optical cable. (Please refer to...) Figure 1 , Figure 2 and Figure 3 ,include:

[0030] Stainless steel wire 4 and elastic protective layer 5 are spirally wound around the outside of flame retardant layer 3, and stainless steel wire 4 and elastic protective layer 5 are fixedly connected to flame retardant layer 3.

[0031] Please see Figure 1 and Figure 3 The cross-section of the stainless steel wire 4 is circular, and the cross-section of the elastic protective layer 5 is rectangular. The elastic protective layer 5 is made of elastic silicone material.

[0032] Please see Figure 1 and Figure 3 The stainless steel wire 4 has a diameter of 0.3mm, the outer diameter of the metal reinforcing member 2 is less than 2mm, and the overall diameter of the optical cable is less than 3mm, so as to be able to be inserted into narrow pipes.

[0033] Please see Figure 1 and Figure 2 The metal reinforcement 2 is fixedly connected to the flame-retardant layer 3, which is made of flame-retardant PE material and has flame-retardant properties.

[0034] Please see Figure 1 and Figure 2 The groove 6 and the metal reinforcement 2 are integrally formed.
