Claim 11

A pluggable module assembly comprising: a metallic mating receptacle cage with a deflectable retaining tab thereon, a housing received in the mating receptacle cage and defining a near end region and a far end region opposite to each other, said near end region comprising a latch portion for being retained in a locking aperture of the retaining tab; a mating port located around the far end region for mating with a corresponding electronic part on a mother board on which the mating receptacle cage is located; a cable extending out of the near end region and away the far end region; an ejector device located around the near end region and essentially back and forth moveable with regard to the housing in a mating direction between outer and inner positions and located at a similar level with regard to the retaining tab, said ejector device including a resisting plate pushing the deflectable retaining tab outwardly in a transverse direction perpendicular to said mating direction when the ejector device is moved backwardly in an un-mating direction opposite to mating direction, and a driving portion extending along said un-mating direction away from the near end region for finger holding so as to move said ejector device backwardly in said un-mating direction toward the outer position for unlatching the latch portion from the retaining tab.

Claim 12

The pluggable module assembly as claimed in claim 9 , wherein said ejector device is further equipped with a spring structure so as to urge the ejector to move in the mating direction to the inner position.

Claim 13

The pluggable module assembly as claimed in claim 9 , wherein said driving portion and said resisting plate are discrete from each other, said driving portion being of insulative material while said resisting plate being of metallid material.

Claim 14

The pluggable module assembly as claimed in claim 11 , wherein said ejector device is further equipped with a spring structure so as to urge the ejector to move in the mating direction to the inner position, said sprint structure being of metallic material and unitarily formed with said resisting plate.

Claim 15

The pluggable module assembly as claimed in claim 9 , wherein said driving portion and said resisting plate are located on a same side with regard to the cable.

Claim 16

A pluggable module for use with a metallic mating receptacle cage with a deflectable retaining tab thereon, said pluggable module comprising: a housing for reception within the mating receptacle cage, defining a near end region and a far end region opposite to each other, said near end region comprising a latch portion for being retained in a locking aperture of the retaining tab; a mating port located around the far end region for mating with a corresponding electronic part on a mother board on which the mating receptacle cage is located; a cable extending out of the near end region and away the far end region; an ejector device located around the near end region and essentially back and forth moveable with regard to the housing in a mating direction between outer and inner positions and located at a similar level with regard to the latching portion, said ejector device including a resisting plate for pushing the deflectable retaining tab outwardly in a transverse direction perpendicular to said mating direction when the ejector device is moved backwardly in an un-mating direction opposite to mating direction, and a driving portion extending along said un-mating direction away from the near end region for finger holding so as to move said ejector device backwardly in said un-mating direction toward the outer position for unlatching the latch portion from the retaining tab.

Claim 17

A pluggable module for use with a metallic mating receptacle cage with a deflectable retaining tab thereon, said pluggable module comprising: a housing for reception within the mating receptacle cage, defining a near end region and a far end region opposite to each other, said near end region comprising a latch portion for being retained in a locking aperture of the retaining tab; a mating port located around the far end region for mating with a corresponding electronic part on a mother board on which the mating receptacle cage is located; a cable extending out of the near end region and away the far end region; an ejector device located around the near end region and essentially back and forth moveable with regard to the housing in a mating direction between outer and inner positions and located at a similar level with regard to the latching portion, said ejector device including a resisting plate for pushing the deflectable retaining tab outwardly in a transverse direction perpendicular to said mating direction when the ejector device is moved backwardly in an un-mating direction opposite to mating direction, and a driving portion extending along said un-mating direction away from the near end region for finger holding so as to move said ejector device backwardly in said un-mating direction toward the outer position for unlatching the latch portion from the retaining tab.
