<p>A right angle header connector (10) is disclosed for mounting on a surface of a printed circuit board (44) wherein the connector includes a dielectric housing (12) having a bottom mounting face (28), a forward mating face (24) and a rearward terminating face (26). A plurality of contact passages (36, 38) are provided in the housing and extending between the forward mating face and the rearward terminating face and defining top and bottom rows and vertical columns of passages, with at least a pair of passages in each column. A plurality of terminals (4) are secured in the passages and have contact sections (16) projecting from the forward mating face and terminating sections (18) projecting from the rearward terminating face connectable to corresponding circuit traces (42) on the printed circuit board. The terminating sections of the contacts in the bottom row (18b) thereof are formed at a first angle, and the terminating sections of the contacts in the top row thereof (18a) are formed at a relatively smaller angle for connection to corresponding rows of circuit traces on the printed circuit board spaced different distances from the rearward terminating face of the housing. The resultant configuration allows the terminals of both rows to have substantially equal electrical pathlengths and therefore eliminates signal delay in high speed applications. Furthermore, the rearward terminating face of the housing compensates for the relatively smaller bending moment of the top row of terminals by recessing the upper row of terminal passages thereby optimizing lead coplanarity. <IMAGE></p> |
