Optical module having a simple mechanism for releasing from a cage

Claim 2

An optical module plugged in a space defined by a cage mounted on a host board, said cage including a resilient latch protruding into said space, comprising: a housing including upper and lower bodies, said upper body including a pair of front side walls each providing first and second projections, said second projection butting against an edge of said resilient latch when said optical module is plugged in said cage; an actuator slidable between first and second positions, said actuator including a pair of front end portions each providing a slot and a pair of arms each extending from said front end portion, said pair of arms sandwiching said front side walls of said upper body therebetween; a receptacle body put between said pair of front end portions of said actuator; and a bail including a pair of arms each providing a hole and a projection and being inserted between said side wall of said upper body and said pair of front end portions of said actuator, each hole of said bail mating with said respective first projection of said upper body and each projection of said bail being inserted into said respective slot of said front end portions of said actuator, wherein said actuator slides from said first position to said second position by pivoting said bail on said first projections of said upper body and sliding said projections of said bail within said slots of said actuator to release said butting of said resilient latch of said cage against said second projections of said upper body.

Claim 3

The optical module according to claim 1 , wherein said bail is set in an upward position or in a downward position relative to said receptacle body when said actuator is set in said first position.

Claim 4

The optical module according to claim 1 , wherein said first position of said actuator corresponds to a position where said projections of said bail are in one end of said slots, and said second position of said actuator corresponds to a position where said projections of said bail are in a center of said slots.

Claim 5

The optical module according to claim 1 , wherein a span between said pair of said front end portions of said actuator is greater than a length between said arms of said bail, said bail being positioned inside of said front end portion of said actuator.

Claim 6

The optical module according to claim 1 , wherein said pair of arms of said actuator each has a forked end with two branches sandwiching said respective second projection of said upper body, and wherein said forked end pushes said resilient latch of said cage outward when said actuator is set in said second position.

Claim 7

The optical module according to claim 5 , wherein said side walls of said upper body each provides a groove in an outer surface thereof to receive each arm of said actuator.

Claim 8

The optical module according to claim 1 , wherein said lower body provides an opening, said second projection of said upper body protruding through said opening to butt against said resilient latch of said cage.

Claim 9

The optical module according to claim 1 , wherein said optical module further includes a spring, said arm of said actuator provides a flange, and said pair of front side walls of said housing each provides a groove to set said spring therein and said flange of said arm, and wherein said spring sets said actuator in said first position when no force is applied to said bail by pushing said flange of said arm with said spring set in said groove.

Claim 10

An optical module plugged in a space defined by a cage mounted on a host board, said cage including a resilient latch protruding into said space, comprising: a housing including upper and lower bodies, said upper body including a pair of front side walls each providing first and second projections and a groove, said second projections butting against an edge of said resilient latch when said optical module is plugged in said cage; an actuator slidable between first and second positions, said actuator including a pair of front end portions each providing a slot and a pair of arms each extending from said front end portion and providing a flange set within said groove of said front side wall of said upper body, said pair of arms sandwiching said front side walls of said upper body therebetween; a receptacle body sandwiched between said pair of front end portions of said actuator; a spring set within said groove of said front side wall of said upper body; and a bail including a pair of arms each providing a hole and a projection and being inserted between said side wall of said upper body and said pair of front end portions of said actuator, each hole of said bail mating with said respective first projections of said upper body and each projection of said bail being inserted into said respective slot of said front end portion of said actuator; wherein said actuator slides from said first position to said second position by pivoting said bail on said first projections of said upper body and sliding said projections of said bail within said respective slots of said actuator to release said butting of said resilient latch of said cage against said second projections of said upper body; and wherein said spring sets said actuator in said first position when no force is applied to said bail by pushing said flange of said arm with said spring.

Claim 11

An optical module plugged in a space defined by a cage mounted on a host board, said cage including a resilient latch protruding into said space, comprising: a housing including upper and lower bodies, said upper body including a pair of front side walls each providing first and second projections and a groove, said second projections butting against an edge of said resilient latch when said optical module is plugged in said cage; an actuator slidable between first and second positions, said actuator including a pair of front end portions each providing a slot and a pair of arms each extending from said front end portion and providing a flange set within said groove of said front side wall of said upper body, said pair of arms sandwiching said front side walls of said upper body therebetween; a receptacle body sandwiched between said pair of front end portions of said actuator; a spring set within said groove of said front side wall of said upper body; and a bail including a pair of arms each providing a hole and a projection and being inserted between said side wall of said upper body and said pair of front end portions of said actuator, each hole of said bail mating with said respective first projections of said upper body and each projection of said bail being inserted into said respective slot of said front end portion of said actuator; wherein said actuator slides from said first position to said second position by pivoting said bail on said first projections of said upper body and sliding said projections of said bail within said respective slots of said actuator to release said butting of said resilient latch of said cage against said second projections of said upper body; and wherein said spring sets said actuator in said first position when no force is applied to said bail by pushing said flange of said arm with said spring.
