Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor optical cables, and particularly relates to a high-strength outdoor optical cable. Background Art

[0002] When outdoor optical cables are laid outdoors, reinforcement components are needed to withstand external mechanical loads to protect the cable body from various external mechanical forces. Although existing high-strength outdoor optical cables can meet people's basic use needs, the reinforcement components used are usually installed on the cable body by snap-fitting. During use, when subjected to external mechanical forces, the reinforcement components are easily deformed, loosened or even fallen off, so there is a defect that they cannot effectively protect the cable body from pressure for a long time.

[0003] For example, the utility model with announcement number CN 217425768 U discloses a high-strength communication optical cable for outdoor use. In the technical solution of this patent, an outer side of the cable outer casing is provided with an outer reinforcement sleeve with the same number as the installation grooves. The outer reinforcement sleeve is clamped to the first fastener through a second fastener. Although this clamping and fixing method can meet the basic requirements of pressure protection, when subjected to strong external mechanical force, the clamping and fixing between the first fastener and the second fastener is easy to loosen or even fall off, resulting in the outer reinforcement sleeve being unable to continue to effectively protect the cable from pressure. Utility Model Content
