Abstract: An electrical connector includes multiple signal terminals and multiple ground terminals paired to form multiple terminal groups and arranged in one row in a body. One signal terminal and one ground terminal form a first terminal group. Two signal terminals form a second terminal group. One ground terminal and one signal terminal form a third terminal group. An arrangement order of the two terminals in the third terminal group is different from an arrangement order of the two terminals in the first terminal group. Each terminal has a conducting portion. The conducting portions of the terminals in a same terminal group bend in a same direction, and the conducting portions of the terminals in adjacent terminal groups bend in opposite directions. The second terminal group is located between the first terminal group and the third terminal group, and between the adjacent ground terminals.

Abstract: An electrical connector includes a body, a soldering portion, an insertion arm, a through hole, and a conductive layer. The soldering portion is disposed on the body. The insertion arm protrudes from the body, and has at least one contact portion. The through hole is formed in the body.

The conductive layer is disposed on the body and the insertion arm to achieve an electrical contact effect. Since the body and the insertion arm are conducted through the conductive layer in the through hole, the electrical connector is easy-to-manufacture without requiring assembly of terminals.

Abstract: An electrical connector includes: an insulating body, having a plurality of terminal slots formed through the insulating body; a plurality of terminals, each correspondingly received in each terminal slot; and at least one recessed portion, recessed on the insulating body and located between at least two terminals, and plated with a metal shielding layer. As the recessed portion is recessed between at least two terminals, the air medium capacity can be adjusted by adjusting the size of the recessed portion, so as to adjust the characteristic impedance between the adjacent terminals to a desired value, thereby improving the high-frequency performance of the electrical connector. Furthermore, the recessed portion is plated with the metal shielding layer, so that the terminals are shielded and prevented from getting in contact with the metal shielding layer, thus avoiding the problem of short circuit.
