Abstract

The invention discloses a shielding twisted-pair conductor connector. The connector comprises a plug and a joint; the plug is electrically connected with a flexible shielding twisted-pair cable core through welding, and the joint is electrically connected with a rigid shielding twisted-pair conductor through welding; the plug and the joint are electrically connected through elastic contact connection of the jack contact piece and the pin contact piece. The insulating layer is designed in a split manner and is divided into the mounting plate and the insulator; according to the shielding twisted-pair conductor joint, the wire cores are independently fixed on the mounting plate, the defects of high core wire bending difficulty, small twisted-pair core wire gap and mutual welding influence areeffectively overcome, the welding spots are contained in the insulator, the creepage distance can be effectively increased, and the insulating property of the shielding twisted-pair conductor joint is improved. The connector provided by the invention has the advantages of excellent structure, good sealing performance, stable electrical performance, strong anti-interference shielding capability and the like, and is a special shielding twisted-pair connector capable of meeting special requirements of radiation resistance, aging resistance and the like.

Description

technical field [0001] The invention relates to the technical field of electronic connection devices, in particular to a shielded twisted-pair conductor connector. Background technique [0002] A large number of electronic and electrical systems and equipment are usually configured in nuclear power plants and engineering test reactors, and various signal interconnections are realized through transmission and control cables between the equipment. Shielded twisted-pair conductor assembly, as one of the new conductor assemblies of third-generation nuclear power plant electrical penetrations, is a widely used transmission medium. Its twisted-pair structure can increase the immunity of transmission lines and prevent the leakage of transmission signals. The shielding layer wrapped outside has a better suppression effect on higher frequency electromagnetic fields, and has good electrical performance and electromagnetic shielding performance. The shielded twisted-pair conductor joi...
