Introduction

Electrical connectors are widely used in rail transit rolling stock for signal transmission and energy transmission: Their performance is critical to the safety of the entire electrical system:

Reliable operation is crucial: In order to provide unified design and selection principles for rolling stock electrical connectors, and to ensure the safety, durability and safety of electrical connectors To work reliably, GB/T 25022 "Electrical Connectors for Rail Transit Rolling Stocks" was formulated: GB/T 25022 is planned to consist of 3 parts:

— Part 1: Vehicle electrical connectors: The purpose is to stipulate the use environment, model marking, structural form and connection of automotive electrical connectors:

The corresponding number arrangement, technical requirements, test methods, inspection rules, packaging and storage, etc:

— Part 2: Power connectors: The purpose is to specify the use environment of the electrical connectors used for power transmission at the end of the car body, model number Marking, structural form and number arrangement of contact pairs, technical requirements, test methods, inspection rules, packaging and storage, etc:

— Part 3: Communication control connector: The purpose is to specify the use of electrical connectors at the ends of the vehicle body for communication and/or control Environment, structural form, model and number arrangement of contact pairs, technical requirements, test methods, inspection rules, packaging and storage, etc:

Rail transit rolling stock electrical connectors Part 3: Communication Control Connector
