High speed rail refers to high-speed rail trains designed for speeds between 250-380 kilometers per hour. Its communication signal system can be regarded as the "central nervous system" and "control brain" for high-speed and high-density operation of high-speed railways, mainly composed of centralized control system (CTC), train control system (CTCS-3 level), station interlocking system (CBI), centralized signal monitoring system (CSM), and power supply system.
At present, with the rapid development of railway transportation in our country, the running speed of trains continues to increase and the operating density continues to increase, which undoubtedly puts forward more stringent requirements for the reliability and safety of high-speed railway communication signal systems.
To cope with the ultra high speed environment during high-speed rail operation, the D-sub connector developed and produced by TXGA adopts a mixed structure of RF connector and current connector. The gold plating thickness of the product contacts reaches 0.75um, and the transmission performance is excellent. In terms of connector design, both sides are equipped with screw free locking structures, which can effectively reduce the risk of male and female head loosening after insertion locking, adding a reliable guarantee for high-speed rail operation. In addition, the plug housing has undergone a special surface treatment process and has the ability to fully shield EMI/RFI interference on high-speed trains, effectively ensuring the stability of equipment signal transmission and providing a safe and reliable fast signal transmission solution for rail transit in ultra high speed environments.
