AI Technical Summary
The lack of reliable cable fixing mechanisms in existing junction boxes makes the terminals prone to poor contact under external vibration and mechanical stress, affecting the stability and reliability of signal transmission.
A built-in bogie signal transfer frame device was designed, which adopts a limiting structure and a fixing structure. Through a precision mechanical transmission system and a self-locking positioning device, it achieves high-precision clamping and stable fixation. Combined with the composite transmission of involute gear pair and precision thread pair, it ensures reliable cable fixation.
It achieves long-term stability and reliability of the signal transmission system. Through modular design and composite transmission scheme, it significantly improves the wear resistance and service life of the equipment, while providing fast and reliable installation and disassembly functions.
