Axis translation installation mechanism for optoelectronics modules and method
View Patent ↗An optoelectronic module is seated onto a substrate connector by guiding the module along an initial path portion that is misaligned with respect to the mating direction defined by the substrate connector and further includes providing a positive pressure drive along an end path portion with sufficient force to secure the optoelectronic module to the substrate connector. Where the mating is via a pin-and-socket arrangement, the positive pressure drive requires sufficient force to push the main body of the module to ensure entry of the pins into the sockets. Typically, there is a conversion from force applied in one direction to module motion in the orthogonal direction. However, a rocking cam embodiment is also described.
1. A device for seating an optoelectronic module onto a connector on a substrate comprising:
a guide structure configured to direct a main body of said optoelectronic module along an insertion direction that is generally perpendicular to a mating direction of said connector, said guide structure comprising a slide having at least one slot formed therein; and
a positive pressure drive enabled to push said main body of said optoelectronic module along said mating direction with sufficient force to secure said optoelectronic module to said connector, said positive pressure drive comprising
a rail having a rail slot formed therein, and
an actuator having a sliding member that is positioned within the rail slot, wherein the sliding member includes at least one projection that extends into the at least one slot formed in the guide structure
wherein the slots of the slide are configured in such a way that motion of the sliding member and its projections in a first direction is translated into motion of the slide in the mating direction.
2. The device of claim 1 wherein said guide structure includes a slide that is perpendicular to said mating direction, said positive pressure drive including an actuator and slots that are aligned with said mating direction, said guide structure being operatively associated with said actuator such that movement of said actuator in alignment with said mating direction controls movement of said slide.
3. The device of claim 1 wherein said guide structure and positive pressure drive define a rocking slide cam in which an angle of said optoelectronic module varies with approach toward a seated condition with said connector, said positive pressure drive including an actuator and at least one actuator pin received within a groove configured to determine said angle of said optoelectronic module.
4. The device of claim 3 wherein said actuator and optoelectronic module are in a fixed relationship with travel of said optoelectronic module along said insertion direction, said actuator being movable relative to said optoelectronic module with travel of said optoelectronic module along said end path portion.
5. The device of claim 1 wherein said positive pressure drive is a mechanical toggle switch having linkage which translates motion of an actuator along an axis perpendicular to said mating direction into motion of said optoelectronic module in said mating direction.
6. The device of claim 1 wherein said positive pressure drive is a stroke multiplier mechanism in which motion of an actuator in a direction perpendicular to said mating direction is translated to motion of said optoelectronic module in said mating direction by orientations of slots.
7. The system of claim 1 wherein said drive mechanism includes linkage for translating force parallel to said substrate into force generally parallel to said substrate.
