Self-compensating connector support method and apparatus
View Patent ↗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.
1. A method for compensating and relieving stress and strain to a printed circuit board (PCB) and its soldering joints upon applied forces being generated from plugging and unplugging of a plug-in connector, the method comprising:
providing a printed circuit board (PCB);
providing a socket connector mounted to the PCB;
providing a back side support assembly, the back side support assembly includes at least a compensating block element, at least a mechanical support member, at least a compliant member with at least a fastening aperture at one end thereof, at least a fastening element, at least a fastening recess in an upper portion of the at least a compensating block element, at least a fastening hole disposed in a top portion of the at least a mechanical support member and at least a guide element disposed on the mechanical support member;
providing the at least a compensating block with a back portion having at least a first wedge-shaped guide surface and a front portion having at least a third guide surface opposite the at least a first guide surface, the at least a fastening recess being disposed in the at least a first guide surface;
providing the at least a mechanical support member with a front portion having at least a second wedge-shaped guide surface that is in sliding relationship to the at least a first guide surface, the at least a guide element being positioned along the at least a second guide surface;
attaching a first end of the at least a compliant member to the top portion of the at least a mechanical support member with the at least a fastening element inserted into the at least a fastening hole via the at least a fastening aperture, a second end of the at least a complaint member being removably secured in the at least a fastening recess of the at least a first guide surface; and
positioning and mounting the back side support assembly relative to the PCB so that the at least a third guide surface is in a sliding interference with the back side portion of the socket connector, wherein the at least a complaint member permits the at least a first guide surface of the at least a compensating block element to slide along the at least a guide element of the at least a second guide surface of the at least a mechanical support member and the at least a third guide surface on the front portion of the at least a compensating block to slide along the back side portion of the socket connector, as a result of the flexing movement of the at least a compliant member, to reduce the forces applied to the socket connector and the PCB when alternating applied forces are generated by the plugging and unplugging of the aforementioned plug-in connector from the socket connector, while simultaneously mitigating damage to the PCB and its soldering joints.
