Patent number: 11495900Abstract: A connector assembly includes an adapter connector and two end-connectors. Each connector includes a high-speed differential area and a low-speed area. The high-speed differential area of each end-connector includes an end differential unit. The high-speed differential area of the adapter connector includes an adapter differential module. Each end differential unit and a corresponding adapter differential unit include a signal contact and a ground shielding member. The plug-in parts of the two end-connectors, which are adapted with the adapter connector, are the same in structure, and of the end differential unit and the adapter differential unit, one is a male unit and the other is a female unit in corresponding plug-in fit. Due to the fact that the plug-in parts of the two end-connectors are the same in structure, when the end-connectors are plugged into the adapter connector, identification can be saved, and blind plugging operation can be directly performed.Type: GrantFiled: July 25, 2019Date of Patent: November 8, 2022Assignees: AVIC JONHON OPTRONIC TECHNOLOGY CO., LTD., NOKIA SHANGHAI BELL CO., LTD.Inventors: Jinhui Fu, Xianjun Pan, Junfeng Yuan, Lufei Ma

Patent number: 11342716Abstract: A connector includes a housing. The housing includes a plurality of module channels therein and shielding net. A signal transmission module is movably mounted in each of the module channels. The signal transmission module includes an insulator and a signal contact member. The shielding net has a plurality of mesh holes. The signal transmission module includes a shielding ring sleeve segment. A shielding contact is conductively bonded to the shielding ring sleeve segment of a corresponding signal transmission module is respectively provided at each mesh hole of the shielding net. The shielding contact protrudes towards the center of the corresponding mesh hole. A plurality of the shielding contacts corresponding to each mesh hole are circumferentially disposed along the corresponding mesh hole. A shielding elastic sheet is conductively bonded to a shielding ring sleeve on each of the signal transmission modules.Type: GrantFiled: July 24, 2019Date of Patent: May 24, 2022Assignee: AVIC JONHON OPTRONIC TECHNOLOGY CO., LTD.Inventors: Junfeng Yuan, Lufei Ma, Zongwei Li
