Patch panel with grounding bump
A patch panel comprises an exposed raised area or bump behind each patch panel opening that maintains electrical conductivity between the patch panel frame and a housing of a jack while the jack is installed in the opening. During the manufacturing process, this grounding bump can be masked from paint or powder coating so that the bare metal of the bump remains exposed, yielding a raised surface that readily makes conducive contact with the conductive casing of a jack installed in the patch panel opening without the need for an intermediate component that would normally be required to bridge the gap caused by paint or powder coat thickness.
