Patent ID: 7402070

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 a latch mechanism comprising: a pair of sliders sliderably attached to the sidewalls and being configured and arranged to linerear move relative to the sidewalls along a mating direction of the plug-in module, each slider comprising an actuating end adapted for latching with a tab of the module receptacle; a bail attached to the sidewalls and one ends of the sliders and being configured and arranged such that the rotate motion of the bail results in the linerear movement of the sliders, the bail comprising a pair of elastic arms integrally formed therewith and capable of linerear movement relative to the sidewalls along a direction perpendicular to the mating direction to provide elastic restore force to the sliders; and wherein the rotation of the bail results in the linerear movement of the elastic arms and the sliders to actuate the actuating ends of the sliders deflecting latch tabs of the module receptacle to separate the plug-in module from the module receptacle; wherein the bail comprises an operating portion across the pair of sidewalls, a pair of cooperating arms downwardly from the operating portion and cooperating with the sliders and the sidewalls, and the pair of elastic arms slantly extending from the cooperating arms to form acute angles with the cooperating arms; wherein each sidewall defines a guiding channel along vertical direction, and wherein each elastic arm forms a distal end received in the guiding channel and is capable of sliding in the guiding channel along said vertical direction which is perpendicular to the mating direction; wherein the plug-in module further comprises a base and a cover respectively comprising first and second sidewalls, and wherein the sliders and the bail are respectively sliderably and rotatably attached to the first and second sidewalls of the base and the cover.
