Monolithic living hinge small form factor transceiver bail-delatch
View Patent ↗A monolithic bail-delatch mechanism is provided for a module plugged into a cage. The bail-delatch mechanism is a single monolithic unit that includes a living hinge connecting a bail and a delatch clip. The living hinge, the bail, and the delatch clip may be made of a single injection molded plastic part. The bail may include cantilever hooks for securing the bail against the module in a latched position. The delatch clip may include a spring mechanism having two spring arms for locking the bail-delatch mechanism to the module, and a delatch fork having tines with wedges for releasing a post of the module from a latch tab of the cage.
1. A monolithic bail-delatch mechanism for a module plugged in a cage, comprising:
a bail;
a delatch clip, comprising:
a spring mechanism comprising two spring arms for locking the delatch clip to the module, the spring arms engaging notches in the module and allowing the delatch clip to have a small travel before locking the delatch clip to the module; and
a delatch fork comprising tines with wedges for releasing a post of the module from a latch tab of the cage, the wedges fitting in angled pockets in the module so that the wedges would rise and push against the latch tab to release the post when the delatch clip is pulled away from the cage;
a living hinge connecting the bail and the delatch clip;
wherein the bail, the delatch clip, and the living hinge comprise a single monolithic part.
2. A monolithic bail-delatch mechanism for a module plugged in a cage, comprising:
a bail;
a delatch clip, comprising:
a clip that locks the delatch clip to the module; and
a wedge that pushes up against a latch tab of the cage to release a post of the module from the latch tab when the delatch clip is pulled away from the cage;
a living hinge connecting the bail and the delatch clip;
wherein the bail, the delatch clip, and the living hinge comprise a single monolithic part.
3. The mechanism of claim 2 , wherein the bail comprises cantilever hooks for securing the bail in a latched position, the cantilever hooks engaging notches in the module.
4. The mechanism of claim 2 , wherein the bail, the delatch clip, and the living hinge comprise a single injection molded plastic part.
5. The mechanism of claim 4 , wherein the living hinge is a thin section of plastic between the bail and the delatch clip.
6. The mechanism of claim 4 , wherein the bail is formed perpendicular to the delatch clip in a latched position.
