A connector includes a connector body and a terminal attached to the connector body, the connector being fitted with a counterpart connector, the connector body includes a recess being fitted with a counterpart connector body of the counterpart connector and side walls extending in a longitudinal direction of the connector body, the side walls defining both sides of the recess. The terminal includes a plurality of terminals disposed along each of the side walls, and the plurality of terminals disposed along each of the side walls include one high frequency terminal and ground terminals disposed on both sides of the high frequency terminal. In plan view, a straight line connecting high frequency terminals disposed along both the side walls is inclined with respect to a center line of the connector body in a width direction, and a shield plate of the counterpart connector is extends along the center line.

An electrical receptacle connector includes a metallic shell, an insulated housing in the metallic shell, a plurality of terminals at the insulated housing, and a metallic plate. The terminals are arranged in two rows, and the metallic plate is at the insulated housing and between the terminals in the two rows. The metallic plate includes a through hole at a front portion of the tongue portion. The through hole has several through portions and a communication portion between the through portions. By allowing that the communication portion to be in communication with the through portions to form a through hole in an elongated shape, the molding efficiency for forming the tongue portion with the filling of the plastic materials can be increased.

An electrical receptacle connector includes a metallic shell, an insulated housing in the metallic shell, a plurality of terminals at the insulated housing, and a metallic plate at the insulated housing. The terminals include two first terminal groups and two second terminal groups arranged in two rows, and the two rows are respectively arranged on the two faces of a tongue portion of the insulated housing. A length of each contact portion of each second terminal group is greater than a length of each contact portion of each first terminal group. The metallic plate is between the first terminal groups and the second terminal groups. The metallic plate has one or more extension portion between the contact portions of at least two adjacent terminals of one or more of the second terminal groups. The structural strength of the tongue portion can be improved by the extension portion.

Plug and receptacle connectors for improving crosstalk are provided. The plug connector includes a first set of plug terminals, a second set of plug terminals, a first plate-shaped shielding member, and a second plate-shaped shielding member. The first set of plug terminals include first ground terminals and first signal terminals, where the first plate-shaped shielding member is provided below the first set of plug terminals. The first plate-shaped shielding member is welded to the first ground terminals and transversely crosses and covers the first signal terminals without contacting the first signal terminals. The second set of plug terminals include second ground terminals and second signal terminals, where the second plate-shaped shielding member is provided above the second set of plug terminals. The second plate-shaped shielding member is welded to the second ground terminals and transversely crosses and covers the second signal terminals without contacting the second signal terminals.

An electric connector assembly includes an insulating housing, a plurality of rows of contact terminals disposed in the insulating housing and including a plurality of signal terminals and a plurality of ground terminals, and a conductive shell assembled on the insulating housing. The conductive shell contacts and is connected with the ground terminals to electrically connect the ground terminals together.

An electrical connector assembly can include a plug connector and a receptacle connector that can mate together. Conductive communication between the plug and receptacle connectors is established by mating signals terminals and mating ground terminals contained in terminal subassemblies accommodated in each connector. To align and support the signal and ground terminals, the terminals may be part of a terminal wafer and the terminal subassembly can be assembled from one or more wafers. The terminal wafer may include grounding features to improve the electrical characteristics and data transmission through the electrical connector assembly.
