A unique self-compensating structure mounted to a printed circuit board (PCB) includes a compensating block element having a back portion with at least a first guide surface and a front portion with at least a third guide surface. A mechanical support member having at least a second guide surface with at least a guide element disposed thereon for sliding engagement with the at least a first guide surface. At least a complaint member cooperatively positioned between a surface on the compensating block element and the at least a third guide surface on the mechanical support member. The at least a third guide surface being cooperatively and movably associated along a back portion of an electrical socket connector via the at least a complaint member for compensating and absorbing external stress and strain of a plug-in connector during alternating plugging and unplugging of the plug-in connector from the socket connector, while simultaneously mitigating damage to the PCB.
