AI Technical Summary
The sealant at the existing rail locomotive wiring harness connections is unstable, prone to cracking, and inconvenient to inspect.
Connector housings are used instead of sealant. Connector housing one and connector housing two are fitted at the wire harness connection and sealed by a sealing ring and a fixing mechanism. This replaces traditional sealant and ensures that the wire harness connection is sealed by the sealing ring 4 set inside the annular groove and the fixing mechanism during use, so that air and water cannot enter the wire harness connection during use.
It improves the stability and convenience of sealing, enables quick inspection of wiring harness faults, reduces assembly difficulty, prevents external corrosion, and ensures that the wiring harness works normally in extreme environments.
