Abstract: An optoelectronic device includes a first semiconductor layer, a second semiconductor layer and an active layer between the first semiconductor layer and the second semiconductor layer; a first insulating layer on the second semiconductor layer and including a plurality of first openings exposing the first semiconductor layer, wherein the first openings include a first group and a second group; a third electrode on the first insulating layer and including a first extended portion and a second extended portion, wherein the first extended portion and the second extended portion are respectively electrically connected to the first semiconductor layer through the first group of the first openings and the second group of the first openings, and wherein the number of the first group of the first openings is different from the number of the second group of the first openings; and a plurality of fourth electrodes on the second insulating layer and electrically connected to the second semiconductor layer, wherein in a

Abstract: An electrical plug connector includes an insulating body, terminals, and a shielding spring member. The terminals include multiple high-speed terminals. Each of the terminals has a docking end to connect to another electrical receptacle connector along an insertion direction. The shielding spring member, partially stacked on the insulating body, includes a sheet-like body, a hollow portion, two first shielding spring fingers, and a second shielding spring finger connected sequentially to form the hollow portion that covers the docking ends of the terminals. The docking end of each of the high-speed terminals relative to an edge between the first shielding spring finger and the hollow portion has a first distance. Each of the docking ends of the remaining terminals relative to an edge between the second shielding spring finger and the hollow portion has a second distance. The first distance is greater than the second distance.
