  • Patent number: 11695227
    Abstract: A connector with a tolerance module includes a socket and a plug adapted to the socket, wherein the socket includes a first housing, the plug includes a tolerance module and a third housing, the tolerance module includes a second housing, the second housing includes second contact members, the second housing is movably arranged on the third housing in a direction perpendicular to the axial direction of the connector, and the second contact members are floatingly assembled in the second housing to enable displacement in the direction perpendicular to the axial direction of the connector. The second housing only generates translational motion without displacement when the connector is inserted. The tolerance of the plug and the socket is realized by the floating assembly of the second contact members in the second housing.

  • Patent number: 11495900
    Abstract: 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.
