An information handling system (IHS) includes a reinforced edge card connector having a terminal block having a mounting surface attached to a surface of a first Printed Circuit Board (PCB). A connector housing has a connector opening aligned to the surface of the PCB to receive an edge of a second PCB. An upper row of upper conductors and a lower row of lower conductors are positioned in respective opposition to frictionally engage opposite sides of the edge of the second PCB, wherein the upper conductors are cantilevered pins. The connector housing exposes a bent portion of the cantilevered pins of the upper row of upper conductors. A flexible sheet is attached to an outward surface of the connector housing and to exposed surfaces of the upper row of upper conductors to create a binding force to multiple cantilevered pins to resist deformation.
