One example of a system includes a system board including first contacts, a cage attached to the system board over the first contacts, and a removable transceiver module including second contacts. The transceiver module is installable in the cage in response to a lateral movement of the transceiver module with respect to the cage to align the second contacts with the first contacts and a vertical movement of the transceiver module with respect to the cage to electrically connect the first contacts to the second contacts.

A functional contactor is provided. The functional contactor according to one embodiment of the present invention comprises: a conductive elastic portion having elasticity and electrically contacting one of a circuit board of an electronic device, a bracket coupled to the circuit board, and a conductor which can come into contact with the human body; a substrate made from a dielectric material and having a groove in either the upper surface or the lower surface thereof; and a functional element comprising a high dielectric material inserted into the groove and made from sintered ceramic having a higher dielectric constant than a dielectric material, a first electrode disposed on the upper surface of the substrate and electrically connected in series to the conductive elastic portion, and a second electrode disposed on the lower surface of the substrate and opposite to the first electrode.

A chassis-mounted electronic device includes a chassis, an upper EMI gasket, and a lower EMI gasket is provided. The chassis, including an upper chassis and a lower chassis, is constructed from a conductive sheet with a first thickness. The upper chassis and the lower chassis are coupled to form an interior of the chassis housing an electronic device. The upper EMI gasket is attached to the upper chassis, and is thinner than the upper chassis. The lower EMI gasket is attached to the lower chassis, and is also thinner than the lower chassis. The upper and lower EMI gaskets include perforations to allow cooling air through the EMI gaskets and into the interior of the chassis. Both the upper EMI gasket and the lower EMI gasket are configured to resiliently contact a portion of the electronic device to provide EMI shielding for the electronic device.

A receptacle cage assembly includes a receptacle cage having first and second side walls extending from a top wall at first and second corners. A gasket has EMI springs electrically connected to the receptacle cage and a panel in a panel opening including top EMI springs and first and second side EMI springs. A first corner EMI spring is located outward of the first corner of the receptacle cage to engage the panel at a first corner of the panel opening. A second corner EMI spring is located outward of the second corner of the receptacle cage to engage the panel at a second corner of the panel opening.

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.

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.

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.

A plurality of electronic circuit boards (2), on which electronic components are mounted, is inserted in parallel through an electronic circuit insertion port (11) of a casing body (1). A gap (3) is formed between front panels (22) of inserted and adjacent electronic circuit boards (2) inserted. A bridge body (5) constituting conduction means electrically conducts a first conductive side portion (22a) of a front panel (22) in one electronic circuit board (2) of adjacent electronic circuit boards (2) and a second conductive side portion (22b) of a front panel (22) in another electronic circuit board (2) that faces the first conductive side portion (22a) via a gap (3).
