A shielding cage assembly () for shielding a plurality of transceiver modules therein includes a conductive hanger (), a conductive upper and a lower shielding cages (), and a spacer (). A plurality of dividing walls () inside the upper and lower shielding cages cooperatively define a plurality of channels for receiving the transceiver modules therein. The spacer is sandwiched between the stacked upper and lower shielding cages. The hanger encloses the shielding cages and the spacer therein and is fixed to a printed circuit board ().

Shielding cage assembly adapted for dense transceiver modules

A shielding cage assembly ( ) for shielding a plurality of transceiver modules ( ) therein includes a connecting cover ( ) and a plurality of transceiver cages ( ). The transceiver cages are arranged in parallel beneath the connecting cover. A plurality of retaining tabs ( ) extends from each conductive cage to pass through corresponding slots ( ) defined through the connecting cover. The connecting cover further includes a plurality of mounting pins ( ) received in corresponding mounting holes ( ) in a printed circuit board ( ). An opening ( ) is defined through the printed circuit board. The transceiver cages are received in the opening with their bottom portions extending below the circuit board.

Small form-factor pluggable transceiver cage

A small form factor pluggable transceiver module ( ) comprises an RJ connector ( ) with a robust interface, a printed circuit board assembly ( ), a cage ( ), a frame ( ) and a latch mechanism ( ). The RJ connector further includes a shielding shell ( ), a housing ( ) received in the shielding shell, an RJ contact module ( ) received in the housing, and an engaging clamp ( ). The RJ connector attaches to the printed circuit board assembly. The engaging clamp provides a stronger, more reliable mechanical connection between the printed circuit board assembly and the RJ connector.

An optoelectrical transceiver module is adapted to be retained in a metal cage ( ). The optoelectrical transceiver module includes a latch ( ) of a housing ( ) of an optoelectrical assembly ( ), an ejector ( ) for disengaging the latch from a retaining tab ( ) of the cage, a de-latching mechanism ( ), an upper cover ( ), and a lower cover ( ). The de-latching mechanism includes a driving device ( ) and a linking rod ( ). The driving device is rotatably attached to the upper cover, and movably engaged with the ejector. Pulling the driving device drives the ejector to slide into the housing, whereupon the latch of the optoelectrical transceiver module is released from the retaining tab of the cage.

SFP packaging with a pull-tab

An electrical connector system ( ) for transmitting electrical signals from a GBIC module inserted in a guide rail ( ) mounted a distance above a printed circuit board ( ) includes a substrate ( ) having upper and lower surfaces ( ), a first connector ( ) mounted on the upper surface of the substrate, and a second connector ( ) mounted on the lower surface of the substrate and electrically connecting with the first connector. The substrate and the second connector together define a receiving space ( ) for receiving another electrical element therein. The second connector comprises a base ( ), a plurality of pins ( ) secured to the base, an insulative extension ( ), and a metal shell ( ) enclosing the base. Each pin has a first end ( ) connecting to the substrate and a second end ( ) connecting to the printed circuit board.

An SFP transceiver cage ( ) comprises a mainframe ( ) and a rectangular grounding device ( ) mounted around a front portion of the mainframe. The mainframe includes two sidewalls ( ), a sidewall cover ( ), a top plate ( ), a bottom wall ( ), and a rear cover. The mainframe and grounding device are each preferably made from a single piece of metal plate. A central spring latch ( ) is formed at a bottom of the mainframe, and two kick-out spring arms ( ) respectively extend from rear edges of the sidewalls. Each kick-out spring arm has a frontmost portion ( ) resiliently abutting against a rear wall ( ) of a corresponding SFP transceiver module ( ) inserted into the cage, and a second portion ( ) resiliently abutting against the rear cover of the cage. The module is thus resiliently and securely received in the cage.
