Shielding structure for locomotive communication bus connector

Abstract

The invention discloses a shielding structure for a locomotive communication bus connector, and the structure comprises a shielding outer housing, an inner housing, a grounding elastic piece, and a hinge frame. The grounding elastic piece is provided with a first end and a second end, and the lower end of the shielding outer housing is connected with the upper end of the inner housing. The first end of the grounding elastic piece is connected with the shielding housing, and the second end of the grounding elastic piece is connected with the inner housing. The inner housing is disposed in the hinge frame, and an arc-shaped curved surface formed by the bending of the grounding elastic piece abuts against the inner wall of the hinge frame.

Description

technical field [0001] The invention relates to a shielding structure of a rail transit locomotive communication connector, in particular to a shielding structure of a locomotive communication bus connector. Background technique [0002] In the field of rail transit, the train communication network serves as an information channel to communicate with various control and diagnostic units, and connects many computer-controlled components on the train to communicate with each other to realize information exchange, so as to achieve the purpose of unified control and diagnosis and resource sharing. The train communication network (including the communication network on subway trains and urban light rail trains) is a control-oriented data communication system connecting on-board equipment and vehicles, and is the core component of the distributed train control and diagnosis system. The structure of train communication network is generally divided into two levels: train bus and veh...

Problems solved by technology

[0003] At present, in the train communication network, the connector of the communication bus usually uses the harting series HGM8 shielding module as the communication connector module. When applied in actual projects, the shielding shell is put into the inner shell made of plastic material, which cannot realize the conduction and grounding relative to the socket shell, which leads to difficulties in communication transmission and increases the safety risk of the train during driving.
