Pluggable modules having latch mechanisms for gripping receptacle assemblies

A pluggable module (100) that includes a module housing (102) having mating and trailing ends (104, 106) and a sidewall (S 1 , S 3 ), that extends therebetween. The sidewall (S 1 , S 3 ), extends along a longitudinal axis (190). The pluggable module (100) further comprises a latch mechanism (108, 100) that is attached to the trailing end (106) of the module housing (102). The latch mechanism (108, 110) includes a coupling arm that extends along the sidewall (S 1 , S 3 ), toward the mating end (104) and also an operator handle that is operatively connected to the coupling arm at a latch joint. The handle projects away from the trailing end (106) of the module housing (102). The handle is configured to be pressed by an actuating force to move the coupling arm into a flexed position. The latch joint moves relative to the module housing (102) when the handle is pressed and the coupling arm moves away from the sidewall (S 1 , S 3 ), to the flexed position. The coupling arm returns toward the sidewall (S 1 , S 3 ), when the actuating force is removed.
