Description

Technical Field

[0001] The utility model relates to a fireproof sleeve, in particular to a fireproof sleeve with high heat dissipation efficiency, belonging to the technical field of sleeves. Background Art

[0002] There are many wiring harnesses in control systems such as rail transit, aviation, military industry, electric power and machine tools. The equipment usually has high-frequency or large-amplitude vibrations during operation. During the vibration, it is easy to cause friction between the wiring harness and the contacting equipment. Long-term friction will damage the wiring harness and cause equipment failure. In order to protect the cables, a layer of network tube is usually placed on the wiring harness to protect the cables, so that the cables inside will not be damaged during the processing. Although the cables are well protected, the existing casings are mostly solid structures, which are not convenient for storage and operation. The heat dissipation effect of the casing is poor, which will cause the cable to be damaged easily during use due to high temperature. Therefore, a fire-proof casing with fast heat dissipation efficiency is needed to improve the above structure. Utility Model Content
