80-Position Right-Angle Receptacle for Dense Board-to-Board Links
The 1734037-1: It carries a 2-row arrangement with outer shroud contacts — the shroud guides the mating header and protects the contacts during blind-mate assembly.
Board Lock and Through-Hole Retention
Board locks are integrated into the housing — these metal anchors solder into plated through-holes and take the shear force off the signal tails when the mated connector sees cable strain or vibration. For an 80-position right-angle part, the board locks are a practical feature: without them, the long lever arm of the mated header would fatigue the solder joints at the outer rows over repeated thermal cycling or handling.
