  • Patent number: 12388221
    Abstract: An electric connector structure includes a base, a tongue piece, a shielding case, a first terminal row, a second terminal row, a middle partition, a first shielding sheet and a second shielding sheet. The shielding case sheathes the base and the tongue. The first terminal row and the second terminal row are disposed on two distal surfaces of the tongue piece. The middle partition is disposed in the tongue piece. The first shielding sheet has a first terminal elastic arm extended toward and abutting against the first terminal row, and a first case elastic arm extended toward and abutting against the shielding case. The second shielding sheet has a second terminal elastic arm extended toward and abutting against the second terminal row, and a second case elastic arm extended toward and abutting against the shielding case. Accordingly, interferences of the electromagnetic wave and the crosstalk are improved.

  • Patent number: 12327963
    Abstract: 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.

  • Publication number: 20230099327
    Abstract: An electrical receptacle connector includes a metallic shell, an outer shell, an insulated housing, and receptacle terminals. The receptacle terminals are held at the insulated housing. The metallic shell covers the insulated housing. The outer shell covers the metallic shell. The metallic shell has a reduced length to allow the exposure of the tongue portion. Elastic pieces of the outer shell extend toward the recessed holes of the metallic shell. When an electrical plug connector is mated with the electrical receptacle connector, the housing of the electrical plug connector contacts the elastic pieces of the electrical receptacle connector, so that the holding force between the electrical plug connector and the electrical receptacle connector can be increased. Hence, when the electrical plug connector is mated with the electrical receptacle connector, the high-frequency interference issue during signal transmission can be reduced.
