A plurality of differential pairs of signal contact (51) and a plurality pairs of ground contact (53) with the pairs of signal contacts (51) arranged therebetween are secured in the connector assembly (1). Each of the differential pairs of signal contact (51) has a first contact engaging portion (511) which is accessible from the female connector (2), and includes a second contact engaging portion (513), extending away from the first engaging portion (511) and accessible from the male connector (3). A shielding bus (10) is electrically interconnecting to at least one of the ground contact (53), and includes a shroud portion substantially enclosing the median portion of the pair of signal contacts (51). ## Claims ### Claim 1 A high speed connector assembly with a shielding system, comprising: a plurality of pairs of differential signal contact terminals and each of the signal contact terminals having a median portion, a first engaging portion extending from the median portion, and a second engaging portion extending from the median portion opposite to the first engaging portion; a plurality of pairs of ground contact terminals with the pairs of signal contact terminals arranged therebetween, wherein at least one of said ground contact terminals has a tail portion angled away from the median portion of one of the signal contacts; and a shielding ground bus having a first portion electrically interconnecting to at least one of the pairs of ground contact terminals, and a second shroud portion different from the first portion and substantially enclosing the median portions of the pair of differential signal contact terminals; the shielding bus further comprising at least one spring arm to interconnect to one of the ground contact terminals. ### Claim 2 (depends on 1) The connector assembly as recited in claim 1, the shielding bus further comprising at least one through hole adjacent to the spring arm for receiving said one of ground contact terminals. ### Claim 3 A high speed connector assembly, comprising: a first connector having a first mating face, and a second connector opposite to the first connector and with a second mating face; a pair of signal contacts arranged between the first and second connector, each with a median portion, a first engaging portion extending from the median portion and accessible in the first mating face, and a second engaging portion extending from the median portion opposite to the first engaging portion and accessible in the second mating face; a pair of ground contacts with the pair of signal contacts arranged therebetween; and a shielding ground bus having a first shroud portion electrically interconnecting to at least one of the ground contact, and a second shroud portion different from the first portion and substantially enclosing the median portions of the pair of signal contacts; wherein the second shroud portion is configured with an upper base and a lower base jointly and substantially fully enclosing the median portions of the corresponding pair of signal contacts. ### Claim 4 (depends on 3) The high speed connector assembly as recited in claim 3, wherein said first connector is linearly opposite to the second connector rather than with any other angles. ### Claim 5 (depends on 3) The high speed connector assembly as recited in claim 3, wherein there are some other contacts disposed in the first connector without extending into the second connector but extending in a direction perpendicular to an axial direction of said shroud portion for mounting to a printed circuit board. ### Claim 6 (depends on 3) The high speed connector assembly as recited in claim 3, wherein at least one of said ground contact has a tail portion angled away from said base portion of one of the signal contacts.
