High speed railway refers to high-speed rail trains with a design speed of 250-380 km/h. Its communication signal system is composed of centralized dispatching control system (CTC), train control system (CTCS-3), station interlocking system (CBI), centralized signal monitoring system (CSM), power supply system, etc. It is the "central nerve" and "control brain" for high-speed rail to realize high-speed and high-density operation. With the rapid development of railway transportation in China, the speed and density of trains are increasing, which puts forward higher requirements for the reliability and safety of high-speed railway communication signal system.
In view of the ultra high-speed environment during high-speed railway operation, the D-sub connector developed and produced by TXGA adopts a mixed RF connector and current connector structure, and the product contact is gold-plated 0.75 um, with outstanding transmission performance. Both sides of the connector are equipped with a screw free locking structure, which can effectively reduce the risk of male and female head loosening after locking the plug. The plug housing can shield EMI/RFI interference on high-speed rail in all directions through special surface treatment process, ensuring the stability of signal transmission of equipment. It provides a safe and reliable fast signal transmission solution for rail transit in the ultra-high speed environment.
