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
