Publication number: 20150236457Abstract: A high-density cable end connector for transmitting high-frequency signals includes a first sub-assembly, a second sub-assembly, a printed circuit board, a shielding plate, and a shielding shell. The first sub-assembly includes first contacts, a first insulator, and a first cover body. The second sub-assembly includes second contacts, a second insulator, and a second cover body. The printed circuit board includes pins connected to the first contacts and the second contacts. The shielding shell at least partially surrounds peripheries of the first sub-assembly and the second sub-assembly. The shielding plate is disposed between the first contacts and the second contacts and fixed to the first insulator or the second insulator for insulating the first contacts from the second contacts. Therefore, the high-density cable end connector is prevented from having crosstalk resulted by high frequency signals between the first contacts and the second contacts.Type: ApplicationFiled: January 21, 2015Publication date: August 20, 2015Inventors: Chien-Yu HSU, Hua-Chun CHANG
