Abstract
Abstract An optical transceiver according to the present invention is a pluggable transceiver to be inserted into a cage of the host system. To release the latching mechanism with the cage, the present transceiver has a bail, a resin-made receptacle member, and a resin-made actuator. The receptacle member attaches the bail in a pivotable arrangement. The bail has a cam to convert its rotation into a seesaw motion of the actuator. The actuator provides a hook in one end thereof, and the seesaw motion of the actuator pulls this hook within the transceiver. Thus, the latching between the transceiver and the cage may be released.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
169 words
A pluggable transceiver to be inserted into and latched with a cage provided in a host system, comprising: a receptacle member having a pair of sides and a center partition, said pair of sides each providing axial projection; a bail, attached to said receptacle member, having a pair of leg portions and a bridge portion connecting said leg portions, each leg portion having an opening to receive said axial projection provided in said receptacle member such that said bail rotates with said axial projection as a center of rotation; and an actuator having an arm portion, a support portion, and a body portion, said arm portion and said body portion capable of moving in seesaw motion with said support portion as a pivot of said motion, said arm portion providing a hook in an end portion thereof to engage with said cage, wherein said bail has a cam for converting said rotation of said bail into said seesaw motion of said actuator to release said hook from said cage.
Claim 2
Dependent Claim
169 words
A pluggable transceiver to be inserted into and latched with a cage provided in a host system, comprising: a receptacle member having a pair of sides and a center partition, said pair of sides each providing axial projection; a bail, attached to said receptacle member, having a pair of leg portions and a bridge portion connecting said leg portions, each leg portion having an opening to receive said axial projection provided in said receptacle member such that said bail rotates with said axial projection as a center of rotation; and an actuator having an arm portion, a support portion, and a body portion, said arm portion and said body portion capable of moving in seesaw motion with said support portion as a pivot of said motion, said arm portion providing a hook in an end portion thereof to engage with said cage, wherein said bail has a cam for converting said rotation of said bail into said seesaw motion of said actuator to release said hook from said cage.
Claim 3
Dependent Claim
31 words
The pluggable transceiver according to claim 1 , wherein said actuator provides an inner sliding surface and an outer sliding surface, said cam being in contact to said inner sliding surface.
Claim 4
Dependent Claim
38 words
The pluggable transceiver according to claim 2 , wherein said leg portion of said bail has a sliding projection in an end portion thereof, said sliding projection being in contact to said outer sliding surface of said actuator.
Claim 5
Dependent Claim
23 words
The pluggable transceiver according to claim 3 , wherein said sliding projection and said cam of said leg portion put said actuator therebetween.
Claim 6
Dependent Claim
42 words
The pluggable transceiver according to claim 3 , wherein said leg portion of said bail has a primary surface including said opening and a secondary surface including said sliding projection, said primary surface and said secondary surface being offset to each other.
Claim 7
Dependent Claim
59 words
The pluggable transceiver according to claim 1 , wherein said cam has a first portion, a second portion, and a third portion, said second portion being substantially linear, and said third portion having a distance to said center of rotation of said bail greater than a distance of said first portion to said center of rotation of said bail.
Claim 8
Dependent Claim
54 words
The pluggable transceiver according to claim 6 , wherein said first portion of said cam is in contact to said inner sliding surface of said actuator and said second portion of said cam makes an predefined angle to said inner sliding surface when said hook provided in said arm portion engages with said cage.
Claim 9
Dependent Claim
25 words
The pluggable transceiver according to claim 7 , wherein said actuator does not start said seesaw motion until said bail rotates by said predefined angle.
Claim 10
Dependent Claim
85 words
The pluggable transceiver according to claim 1 , wherein said axial projection provided in said receptacle member has a shape including two circles concentric to each other with a portion of said outer circle being cut to expose said inner circle, and wherein said opening provided in said leg portion has a stopper projection in an edge thereof, said stopper projection being received in and abutting against said cut portion of said axial projection of said receptacle member to control said rotation of said bail.
Claim 11
Dependent Claim
36 words
The pluggable transceiver according to claim 1 , wherein said receptacle member has a rib in said side thereof, said leg portion of said bail abutting against said rib to control said rotation of said bail.
Claim 12
Dependent Claim
26 words
The pluggable transceiver according to claim 1 , wherein said actuator causes said rotation of said bail by pressing a front end of said actuator downward.
Claim 13
Dependent Claim
24 words
The pluggable transceiver according to claim 1 , further comprises a cover providing a tab in a front bottom thereof to support said actuator.
Claim 14
Dependent Claim
34 words
The pluggable transceiver according to claim 1 , wherein said bridge portion of said bail has a convex shape warping to a direction opposite to a space sandwiched by said pair of leg portions.
Claim 15
Dependent Claim
43 words
The pluggable transceiver according to claim 1 , wherein said center partition of said receptacle member provides a axial projection, and said bridge portion of said bail provides a dimple to receive said axial projection of said center partition of said receptacle member.
Claim 16
Dependent Claim
29 words
The pluggable transceiver according to claim 1 , wherein said bridge portion of said bail provides a projection in a surface facing said center partition of said receptacle member.
Claim 17
Dependent Claim
31 words
The pluggable transceiver according to claim 15 , wherein said center partition of said receptacle member provides a dimple to receive said projection formed in said bridge portion of said bail.
