Abstract
Abstract An electrical connector of the present invention includes an insulative housing ( 10 ) and a contact insert ( 12 ) attached to the housing. The contact insert includes eight singnal contacts ( 26 a- 26 h ) and two grounding contacts ( 28 a, 28 b ) arranged side by side and an upper printed substrate ( 30 ) and a lower printed substrate ( 32 ) sandwiching the singnal contacts and the grounding contacts therebetween. Two selected singnal contacts ( 26 c, 26 f ) each are severed into three pieces but the other contacts ( 26 a, 26 b, 26 d, 26 e, 26 g, and 26 h ) are not severed. Two end portions ( 58 a, 58 b; 56 a, 56 b ) of the severed contacts are re-routed by conductive traces on the upper lower printed substrates, while the middle portions ( 58 c, 56 c ) are grounded. Therefore, lengths inducing electrical capacitances between the severed contacts and the adjacent contacts can be reasonably reduced, thereby reducing crosstalk between the severed contacts and the adjacent contacts.
