𐄀 Technology Connection to Future
Yonggui Electric Coupler team has more than ten years of electric hook product development, production and maintenance experience, with strong research ability and rich practical experience. By April 2023, the Yonggui Electric team completed 21 urban rail and 8 Chinese standard EMUs electric coupler (Nano E-Coupler in following paragraphy) maintenance service projects.The maintenance projects included E-coupler from oversea suppliers such as Voith,Dellner, Faiveley etc.
The electric coupler is Plug-Socket interconnection structure, which is composed of a flip assembly, a shell assembly, an insulator assembly, a cable assembly and rear accessories. The contacts are of the elastic end face and pinhole type.
Yonggui Technologys current commonly used electric coupler core numbers include 32, 40, 46, 50, 60, 70, 75, 89, 105, 140, 164, 196, 202, etc. It can provide products with different structures and core numbers according to user needs. The electric coupler adopts different specifications of elastic end contacts or pinhole parts to meet the application requirements of different voltages and currents. It integrates various signals such as power supply, control and communication, and has the characteristics of high technical content, reliable contact, easy installation and fast maintenance.
With the rapid development of information technology, the railway system has higher and higher requirements for network signal transmission. For this reason, the electric coupler can simultaneously add Ethernet function modules to provide 100Mbps and 1000Mbps network transmission. Ethernet module has the characteristics of stable and reliable signal transmission, convenient installation, and front-end maintenance.
Yonggui Technology electric couplers are currently used in hundreds of projects at home and abroad. Electric couplers have various structures and good application effects. The domestic electric coupler market share reaches more than 65%.
