An electrical connector is used to be electrically connected to a mating component. The electrical connector includes one or more shielding members, forming multiple receiving holes; and multiple terminals, including at least one signal terminal and at least one ground terminal correspondingly accommodated in the receiving holes. The ground terminal has a mating portion upward abutting the mating component, an elastic portion pressed vertically to elastically deform, and a positioning portion having a cross-section in a circular shape. The positioning portion and the shielding members are conductively connected to each other by at least three conductive portions, and the three conductive portions are provided to form a triangle. An insulating block is between the signal terminal and a corresponding shielding member to be accommodated in a corresponding receiving hole. The positioning portion with a circular cross-section has a larger area when the volume of the receiving hole remains unchanged.

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 connector includes an insulating case and a first terminal set including a first grounding terminal set, a first signal terminal set and a second signal terminal set arranged at intervals in the horizontal direction. The first grounding terminal set includes a first grounding terminal, a second grounding terminal and a third grounding terminal. The first signal terminal set is vertically staggered between the first grounding terminal and the second grounding terminal and includes a first signal terminal and a second signal terminal arranged at intervals in the vertical direction. The second signal terminal set is vertically staggered between the second grounding terminal and the third grounding terminal and includes a third signal terminal and a fourth signal terminal arranged at intervals in the vertical direction.

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.
