A door assembly is described. The door assembly includes a door structure that is mounted over an opening of an enclosure. The door structure includes a body that includes a first surface and a second surface opposite to the first surface. The first surface may face an inside of the enclosure when the door structure is closed. The door structure includes a number of finger bracket structures mounted on the first surface. Each one of the finger bracket structures includes a bracket and one or more finger gaskets coupled to the bracket. The finger gaskets of the finger bracket structures may contact enclosure brackets mounted around an edge of the opening of the enclosure when the door structure is closed. A combination of the finger gaskets in contact with enclosure brackets may create an electromagnetic interference (EMI) shield at the edge of the opening of the enclosure.

A receptacle cage includes cage walls extending between a front end and a rear end including a top wall and side walls forming a module channel receiving a pluggable module. The receptacle cage includes a gasket at the front end having EMI springs electrically connected to the cage walls. Each EMI spring has a deflectable portion between a base and a distal end. The distal end is split with a first end beam and a second end beam at the distal end separated by a gap. The deflectable portion is spaced apart from the cage wall and is deflectable toward the cage wall. Each EMI spring has first and second side edges between the base and the distal end. The EMI springs are arranged side-by-side without gaps between adjacent EMI springs.

Provided are a functional contactor and a portable electronic device comprising same. A functional contactor, according to an embodiment of the present invention, comprises: an elastic conductor which electrically comes in contact with a conductor of an electronic device; a functional element which is connected to the elastic conductor and has a first electrode and a second electrode on at least one part of the lower side and the upper side, respectively; a first testing electrode which is connected to the first electrode and is provided on the upper side of the functional element and a fixed distance away from the second electrode; and a second testing electrode which is connected to the second electrode and is provided on the upper side of the functional element.

In one example in accordance with the present disclosure an electro-magnetic interference (EMI) containment device is described. The EMI containment device includes a number of spring devices to maintain contact between an electronic module and an enclosure. The spring device includes a spring portion to contact an electronic module disposed in the enclosure. A guide device of the spring device controls movement of the spring portion and an alignment mechanism maintains alignment of the spring portion.

A cassette for insertion and removal of an edge-connected printed circuit card connectable to a server chassis is disclosed. The cassette includes a housing comprising a bottom wall having at least one elongated slot and a catch formed thereon. The cassette further includes a connector sub-assembly overlying the bottom wall having an edge connector socket formed thereon and configured to receive the edge-connected printed circuit card. The cassette further includes a guide sub-assembly underlying the bottom wall having a spring latch formed thereon. The spring latch is operable in a first state to engage the catch to prevent movement of the connector sub-assembly and the guide sub-assembly relative to the housing. The spring latch is operable in a second state to clear the catch to permit the connector sub-assembly and the guide sub-assembly to slide in unison in the at least one elongated slot.

Rack-mountable assemblies are provided which include a cover configured to fixedly mount to a frame of an electronics rack, and a drawer configured to slidably mount to the frame adjacent to the cover to slide relative to the cover. When operatively mounted to the frame, the cover and drawer together define an enclosure for one or more electronic components. The assembly further includes an electromagnetic shielding structure to provide, at least in part, electromagnetic shielding at a gap between the cover and drawer when operatively positioned within the electronics rack. The electromagnetic shielding structure includes an electromagnetic shielding plate which overlies, at least in part, the gap between the cover and the drawer, and which self-adjusts with sliding of the drawer into the electronics rack to facilitate providing the electromagnetic shielding at the gap between the cover and the drawer.

A receptacle includes a cage, a bezel opening in the cage, and at least one bezel clip mounted adjacent to the bezel opening. The at least one bezel clip includes first bezel fingers and second bezel fingers. The first bezel fingers are located along an inner surface of the cage. The second bezel fingers include outer fingers located along an outer surface of the cage and inner fingers located along the inner surface of the cage. The inner and outer fingers of the second bezel fingers are defined by the second bezel fingers passing through a through hole in the cage.

An electromagnetic shielding structure uses at least one expansion card blank to cover an expansion card window. The expansion card blank includes a plate body, a fixing portion, an abutting portion, and an adjoining portion. The fixing portion and the abutting portion are connected to two opposite sides of the plate body respectively. The adjoining portion is connected to another side of the plate body. The expansion card blank is fixed to the expansion card window through the fixing portion and the abutting portion, so as to cover the expansion card window. In different practical instances, the adjoining portion touches a side fringe portion of the expansion card window, the plate body of another adjacent expansion card blank, or a fixing plate of an adjacent expansion card, so that the expansion card window can be covered completely for electromagnetic shielding.
