Abstract
A delatch mechanism includes wedges that reside in pockets adjacent to a post on a module when the module is latched in a cage. Pulling on a handle pulls the wedges out of the pockets so that the wedges rise and lift a tab. Pulling the delatch mechanism to a limit of its motion frees the post on the module from the tab, and further pulling transfers to the module to pull the module out of the cage. The delatch mechanism can include a spring system that returns the wedges to their pockets for latching, allows movement of the wedges relative to the module for lifting of the tab, and locks into the module to pull the module free of the cage. Handles for the latch mechanism can include a bail, a flexible tab, or fixed handle that is part of an integrated structure including the wedges.
Claims14
A module assembly comprising:
- a module body including a latch post and a pocket adjacent the latch post, wherein the latch post and the pocket are features of a single integrated structure;
- and
- a delatch mechanism including a wedge with a top that is below a top of the latch post when the wedge is in the pocket, wherein the wedge rises out of the pocket so that the top of the wedge is at or above the top of the latch post when the delatch mechanism is pulled from a first position to a second position.
A module assembly comprising:
- a module body including a latch post and a pocket adjacent the latch post;
- a delatch mechanism including a wedge with a top that is below a top of the latch post when the wedge is in the pocket, wherein the wedge rises out of the pocket so that the top of the wedge is at or above the top of the latch post when the delatch mechanism is pulled from a first position to a second position;
- and
- a spring system attached so that pulling the delatch mechanism from the first position to the second position compresses the spring system and transfers pulling force to the module body.
A module assembly comprising:
- a module body including a latch post and a pocket adjacent the latch post;
- a delatch mechanism including a wedge with a top that is below a top of the latch post when the wedge is in the pocket, wherein the wedge rises out of the pocket so that the top of the wedge is at or above the top of the latch post when the delatch mechanism is pulled from a first position to a second position;
- and
- a handle that enables a user to pull on the delatch mechanism, wherein the handle comprises a flexible tab that is looped though an opening in an integrated structure that includes the wedge.
A method for removing a module from a cage, comprising:
- pulling a delatch mechanism from a first position to a second position relative to the module, wherein pulling the delatch mechanism from the first position to the second position pulls the wedge from a pocket in the module, causing the wedge to rise and lift a tab on the cage to free a post on the module from a hole in the tab;
- and
- after pulling the delatch mechanism to the second position, further pulling the delatch mechanism to slide the module out of the cage, wherein in the second position the delatch mechanism is fixed relative to the module so that the further pulling applies force to the module to remove the module from the cage.
A method for removing a module from a cage, comprising:
- pulling a delatch mechanism from a first position to a second position relative to the module, wherein pulling the delatch mechanism from the first position to the second position moves a wedge causing the wedge to lift a tab on the cage to free a post on the module from a hole in the tab and compresses a spring system that transfers pulling force to the module;
- and
- after pulling the delatch mechanism to the second position, further pulling the delatch mechanism to slide the module out of the cage, wherein in the second position the delatch mechanism is fixed relative to the module so that the further pulling applies force to the module to remove the module from the cage.
