The invention specifically relates to a combined shielding module circular connector for a high-speed bullet train. The circular connector comprises an integrated insulator, a housing and a pluralityof circular shielding modules arranged in the insulator. The integrated insulator is arranged in the housing. Each circular shielding module comprises a shielding housing, a shielding pressing sleeve,a module insulator and a contact member arranged in the module insulator. The module insulator is arranged in the shielding housing. The end portion in the shielding housing is detachably provided with the shielding pressing sleeve. A cable passes through the shielding pressing sleeve and is connected with the contact member. The shielding housing is provided with a gear sleeve, which is used forfixing the shielding housing in the integrated insulator. The connector is highly integrated; the number of the connectors is reduced, and occupation space of the connectors in a vehicle is small; and the vehicle weight is reduced, the structure is simple, assembly is convenient and an economical and practical effect is achieved.
Description
technical field [0001] The invention belongs to the technical field of electrical connectors for high-speed motor vehicles, and in particular relates to a circular connector for a combined shielding module for high-speed motor vehicles. Background technique [0002] Most of the existing circular connectors do not have shielded wires connected to the connector housing, or there is shielding but only the overall total shielding. The speed of high-speed trains is very fast, and the signal interference between each control unit is very large. It is especially important that the unit control connectors are individually shielded. Each unit of the existing circular shielded connector is a plurality of separate connectors. On the one hand, the number of connectors is large, occupying more positions on the vehicle, increasing the weight of the vehicle, and on the other hand, increasing the overall cost. Contents of the invention [0003] Aiming at the deficiencies of the prior art...
