Patent ID: 7422457

Claim:
A plug-in module configured for latching engagement with a module receptacle adapted for mounting to a printed circuit board, comprising: opposite sidewalls parallel to each other and extending along a longitudinal direction parallel to a mating direction of the plug-in module; and a latch mechanism comprising: an actuating member rotatably assembled to the sidewalls and comprising a pair of actuating arms each formed with an actuating end at one distal end thereof, and an operating portion across the sidewalls along a lateral direction perpendicular to said longitudinal direction and connecting the other distal ends of the pair of actuating arms; and a pair of ejectors rotatably assembled to the sidewalls to cooperate with the actuating ends of the actuating member; and wherein the actuating member is configured and arranged such that movement of the operating portion thereof in up-to-down direction results in down-to-upward movement of the actuating arms and the actuating ends to thereby actuate the ejectors outwardly rotate relative to the sidewalls deflecting the latch tab of the module receptacle to separate the plug-in module from the module receptacle; and wherein the actuating member comprises a pair of elastic spring arms integrally formed with the actuating arms and being compressed with the movement of the actuating member in up-to-down direction and providing elastic restore force to the actuating member to actuate the actuating member and the ejectors to their original positions.
