Abstract: An electrical receptacle connector includes an insulator, a first contact set, a second contact set, a U-shaped shielding structure, and a first plate member. The insulator includes a tongue and a base connected to the tongue. The first contact set and the second contact set are disposed inside the insulator and exposed out of a first side and a second side of the tongue opposite to each other. The U-shaped shielding structure is disposed on the base and at least partially exposed out of the base. The first plate member extends from an end portion of the U-shaped shielding structure along a third side adjacent to the first side and the second side of the tongue and toward a front end of the tongue. The first plate member includes a first step structure. Therefore, it effectively prevents the tongue from being worn or deformed by insertion and withdrawal forces.

Abstract: A connector is disclosed in this invention, comprising a connector body, a first terminal set, a second terminal set, and a third terminal set. The connector body comprises accommodating space, the accommodating space comprises a plug-in socket near one end of the connector body, and a side wall of the accommodating space close to the plug-in socket of the connector body is extended internally to form a protrusion. The first terminal set is installed inside the accommodating space and located near the other terminal of the connector body. The second terminal set is installed inside the accommodating space and located near the terminal of the connector body. The third terminal set is installed inside the accommodating space and located near the terminal of the connector body, and the second terminal set and the third terminal set are located at two sides of protrusion, respectively.
