ABSTRACT:
A pluggable module actuation and retention device comprising a spring housing fastened to a printed circuit board and having openings which contain a matrix of contact springs extending from said board. A bail retaining latch is fastened to the spring housing and an actuator bail is pivotally mounted on the spring housing and has an opening which overlies the openings in the spring housing. A module to be actuated and retained has a matrix of pins corresponding to the matrix of contact springs and is provided with actuator tabs. Actuator tab mating means are provided on the spring housing for engaging the module actuator tabs when a module is inserted through the opening in the actuator bail to align the matrix of pins with the matrix of contact springs. Camming means on the actuator bail are effective when the bail is pivoted in one direction to engage the actuator tabs and slide the module to move the matrix of pins on the module into engagement with the matrix of contact springs. Arm portions on the bail are engaged by the bail retaining latch when the pins and contact springs are engaged.
