Description

Technical Field

[0001] The utility model relates to the technical field of trachea connection, in particular to a trachea connector. Background Art

[0002] Tracheal connectors, a key component connecting trachea to other equipment or pipelines, are commonly found in medical, industrial, and mechanical equipment. They offer numerous advantages and features, providing efficient and reliable connection solutions for a wide range of applications. Their excellent sealing properties ensure smooth flow of gas or liquids and effectively prevent leaks. Overall, tracheal connectors are powerful, high-performance connection components used in a wide range of applications. Whether medical, industrial, or mechanical, they are essential.

[0003] After searching, it was found that the air tightness of the connection between the existing trachea connector and the air inlet pipe is poor. Over time, the pipe is likely to loosen and fall off, affecting the sealing of the trachea connection. When removing the carrier board, the trachea needs to be pulled out. If you forget to take it out, the trachea or the trachea head will be damaged, which will affect the appearance and the trachea layout will be messy. When removing the carrier board, the trachea needs to be pulled out. If you forget to take it out, the trachea or the trachea head will be damaged. The suction cup is placed on the inner surface of the PCBA, and the trachea will interfere with the test pin point, which will affect the appearance and the trachea layout will be messy.
