Press-fit EMI shield and electronic devices including same
View Patent ↗An electromagnetic shield for a storage device comprising a printed circuit board (PCBA) defining a plated through hole defining a generally cylindrical plated surface. The electromagnetic shield may comprise a top surface and sides oriented generally perpendicular to the top surface. One or more of the sides comprise a press-fit connector configured for removable insertion in the plated through hole. The press-fit connector may comprise at least one resilient member defining a longitudinal axis and configured to resiliently bow out in a direction generally perpendicular to the longitudinal axis during insertion and press against the plated surface of the through hole to displace plating material formed thereon to form a gas-tight seal between the at least one resilient member and the plated surface.

8. The data storage device of claim 7 , wherein the tapered free end is further configured to guide insertion into the through-hole.
9. The data storage device of claim 7 , wherein the tapered free end defines a distal portion having a width smaller than a diameter of the through-hole and a proximal portion having a width larger than the diameter of the through-hole.
10. The data storage device of claim 7 , wherein the first resilient member is configured to bow out away from the longitudinal axis in a first direction and wherein the second resilient member is configured to bow out away from the longitudinal axis in a second direction generally opposite the first direction, during insertion of the press-fit connector into the through-hole.
11. The data storage device of claim 7 , wherein the first and second resilient members comprise at least one corner that is configured to press against the plated surface of the through-hole and to displace the plating material or oxide during insertion of the press-fit connector into the through-hole.
