Abstract
Abstract A case containing an optical interface section including a connector-fitting unit in its front portion, a printed board in its central portion, and an electrical interface section in its rear portion is accommodated in a housing. When a data link module is inserted in a cage, a housing tongue and a through hole both formed in a bottom plate of the housing are overlapped with a cage tongue and a lock pin both provided in and on a bottom plate of the cage, into and from which the data link module is inserted and removed, such that the lock pin is engaged in and locked by the lock hole. When removing the data link module from the cage, by angularly turning a bail pivotally supported by the connector-fitting unit, the cage tongue is pushed down following to the housing tongue with the camming operation of a plate cam, thus causing the lock hole to be disengaged from the lock pin.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A data link module having a cage capable of inserting thereto and pulling out therefrom an optical module, comprising: a housing encasing the optical module; a housing tongue formed on the housing and provided with a housing lock hole, the housing tongue capable of being biased; a cage tongue formed on the cage, the cage tongue capable of being biased; a cage lock hole formed on the cage tongue; a lock pin formed on the optical module, the lock pin being projected from both the housing lock hole and the cage lock hole so as to be locked to the cage, upon inserting the optical module into the cage; and a bail combined with the optical module, the bail including a pivot and a cam around the pivot, the cam being adapted to press the housing tongue and thereby moving the cage tongue, wherein the bail disengages the cage lock hole from the lock pin by being rotated around the pivot.
Claim 2
Dependent Claim
161 words
A data link module having a cage capable of inserting thereto and pulling out therefrom an optical module, comprising: a housing encasing the optical module; a housing tongue formed on the housing and provided with a housing lock hole, the housing tongue capable of being biased; a cage tongue formed on the cage, the cage tongue capable of being biased; a cage lock hole formed on the cage tongue; a lock pin formed on the optical module, the lock pin being projected from both the housing lock hole and the cage lock hole so as to be locked to the cage, upon inserting the optical module into the cage; and a bail combined with the optical module, the bail including a pivot and a cam around the pivot, the cam being adapted to press the housing tongue and thereby moving the cage tongue, wherein the bail disengages the cage lock hole from the lock pin by being rotated around the pivot.
Claim 3
Dependent Claim
23 words
The data link module of claim 1 , wherein both the housing tongue and the cage tongue are made of a resilient material.
Claim 4
Dependent Claim
17 words
The data link module of claim 1 , wherein the housing is made of a resilient material.
Claim 5
Dependent Claim
26 words
