Abstract

The invention provides a rectangular differential circuit electrical connector for a high-speed train. The rectangular differential circuit electrical connector comprises a plug shell, a socket shell,a cable, a shielding layer fixing part and a contact piece. The rectangular differential circuit electrical connector conforms to structure and requirement of a differential circuit, the structure ofthe electrical connector can be safely and reliably connected and transmits a corresponding control current signal and a communication network signal, connection of a multi-path differential circuitcan be achieved by an additive arrangement device, the detachable contact piece is used, the electrical connector is convenient to disassemble and install, the cable shielding layer and a cable outerlayer are pressed at a fixed position of an all-metal shell, so that a complete shielding field is formed in the shell, invasion of an external interference source is prevented, and meanwhile, a signal in the shielding field is also prevented from being leaked to the outside.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a rectangular differential circuit electrical connector for high-speed trains. Background technique [0002] In the process of the high-speed train being developed in our country, it is found that the control signal and electrical signal are distorted, intermittent and incomplete during the train operation. After analysis, test and inspection, it is found that the structure and arrangement of electrical connectors and cables (wires) do not completely and effectively protect various sources of interference. Common structural types of electrical connectors are only responsible for the connection and transmission of circuits or other signal channels, and the interference and invasion of the interaction of the circuit itself appear to be powerless. In the transmission of various electrical signals, the electrical radiation generated by different types of signal sources...
