Patent ID: 8439615

Claim:
A face plate assembly for EMI shielding of a printed circuit board and for mounting the printed circuit board onto a rack, the assembly comprising: a one-piece molded face plate comprising an electrically conductive thermoplastic material further comprising a thermoplastic polymer containing conductive additives, said face plate having opposed planar surfaces: an outer planar surface for receiving a captive screw, and an inner planar surface for contacting and securing a printed circuit board and mounting the printed circuit board onto a rack, and said face plate further comprising at least one integral retaining element; at least one captive screw for insertion in a retaining element molded into the face plate and for attachment to a rack, wherein the captive screw has a shank portion and a thread portion, the thread portion having an inner diameter D SI and an outer diameter D SO , and the shank portion having a diameter D SHANK ; said at least one retaining element being adapted to secure the captive screw in place on the face plate, the retaining element having a circular indentation with a diameter D HI extending partially through the retaining element, and a hole within the circular indentation extending through the retaining element with a diameter D H , the retaining element further including at least one slot extending from the outer periphery of the retaining element to hole D H , wherein the retaining element slot enables the retaining element to expand to accommodate the captive screw as the thread portion passes through the hole, and to lock the shank portion of the screw in place when the thread portion of the screw has passed through the hole, and a printed circuit board secured to the inner surface of the face plate.
