Pull type latch mechanism for removable small form factor electronic modules

A pull-to-release latch for latching a module into a mating port, comprising:

• a module comprising a frame member, said frame member comprising a journal for supporting a latch member;
• said latch member comprising a transverse shaft supported in a pivotable manner by said journal of said frame member;
• an actuator member disposed intermediate and engageable with said frame member and said latch member;
• said frame member comprising at least a wedge member projecting therefrom;
• said latch member disposed juxtaposed with said frame member;
• said latch member further comprising at least a wedge member proximate one end of said latch member juxtaposed with at least said wedge member of said frame member and a latching surface on a second end thereof;
• said actuator member comprising a portion engageable with said wedge members of said frame member and with said wedge member of said latch member;
• said wedge members on both said latch member and said frame member projecting toward each other;
• said portion of said actuator member disposed for movement from an unactuated position and an actuated position, said actuated position corresponding to a position in which said latch member is displaced to release said module from said port, and
• said portion of said actuator displaceable intermediate said wedge members spreading said frame member from said latch member, displacing said latch member to an actuated position, thereby rotating said second end toward said frame member, releasing said module from a latched condition relative to said port.

A pull-to release latch for latching a module in a port in a host device comprising:

• a module having at least a frame, said frame comprising at least one journal;
• a latch member moveably disposed on said frame and pivotally supported in said journal, said latch member having a latching end forming a latching surface said latching end movable toward and away from said frame to disengage and engage said latching surface with a retaining surface disposed on said host device and proximate said port and an other end, said other end comprising a camming surface facing said frame;
• and
• a manually movable actuator member disposed intermediate said latch member and said frame and displaceable to engage with said frame and engage and displace said camming surface of said latch member relative to said frame thereby displacing said latching end relatively inward toward said frame and away from to said retaining surface effecting disengagement therefrom.
