Abstract
Abstract The present invention relates to a delatching mechanism for an electronic module, such as an opto-electronic transceiver or a copper transceiver, for locking the electronic module in a host cage. The delatching mechanism enables a conventional small form factor (SFP) sized module to be unlatched while a cable remains engaged therein. A manually engageable lever, such as a bail handle, is rotatably connected on one end of a pivoting latch, and includes a projection for abutting against the module housing for distributing the force applied to the bail to one end of the pivoting latch, whereby the other end of the pivoting latch rotates away from engagement with the host cage.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
125 words
An electronic module for plugging into a host receptacle comprising: a housing having a first abutment surface; a printed circuit board mounted within the housing having an electrical connector at one end thereof for electrically connecting the module to a mating connector in the host receptacle; a latch pivotally connected to the housing about a first axis for releasably holding the module in the host receptacle; a lever pivotally connected to the latch about a second axis, the lever including a first camming surface; whereby the lever rotates about the second axis until the first camming surface abuts the first abutment surface, thereafter continued rotation of the lever causes rotation of the latch about the first axis for disengaging the latch from the host receptacle.
Claim 2
Dependent Claim
125 words
An electronic module for plugging into a host receptacle comprising: a housing having a first abutment surface; a printed circuit board mounted within the housing having an electrical connector at one end thereof for electrically connecting the module to a mating connector in the host receptacle; a latch pivotally connected to the housing about a first axis for releasably holding the module in the host receptacle; a lever pivotally connected to the latch about a second axis, the lever including a first camming surface; whereby the lever rotates about the second axis until the first camming surface abuts the first abutment surface, thereafter continued rotation of the lever causes rotation of the latch about the first axis for disengaging the latch from the host receptacle.
Claim 3
Dependent Claim
33 words
The module according to claim 1 , wherein continued rotation of the lever causes rotation of the lever about a third axis defined by the first camming surface intersecting the first abutment surface.
Claim 4
Dependent Claim
34 words
The module according to claim 2 , wherein the lever includes a projection, with the first camming surface, extending from an end thereof into a recess, with the first abutment surface, in the housing.
Claim 5
Dependent Claim
22 words
The module according to claim 3 , wherein the projection includes a rounded surface enabling rotation of the lever inside the recess.
Claim 6
Dependent Claim
13 words
The module according to claim 1 , wherein the lever comprises a bail.
Claim 7
Dependent Claim
57 words
The module according to claim 5 , wherein the bail includes a first side arm pivotally connected to the latch, a first projection extending from a first end of the first side arm, and a cross bar extending from a second end of the first side arm; and wherein the first projection includes the first camming surface.
Claim 8
Dependent Claim
59 words
The module according to claim 6 , wherein the bail further comprises: a second side arm, a first end of which is pivotally connected to the latch and a second end of which is fixed to the cross bar; and a second projection extending from the first end of the second side arm with a second camming surface thereon.
Claim 9
Dependent Claim
39 words
The module according to claim 7 , wherein continued rotation of the lever causes rotation of the lever about a third axis defined by the first and second camming surfaces intersecting the first and a second abutment surfaces, respectively.
Claim 10
Dependent Claim
37 words
The module according to claim 7 , further comprising a pivot pin extending through the first end of the first side arm, the first end of the second side arm, and a first end of the latch.
Claim 11
Dependent Claim
29 words
The module according to claim 9 , further comprising a hook extending from a second end of the latch for engaging a mating latching member on the host receptacle.
Claim 12
Dependent Claim
22 words
The module according to claim 7 , further comprising a cable fixed to the printed circuit board extending outwardly from the housing.
Claim 13
Dependent Claim
49 words
The module according to claim 11 , wherein the first and second side arms each include an elbow section proximate the second ends thereof; whereby the cross bar extends across a top of the housing, thereby enabling the bail to rotate through a greater angle before contacting the cable.
Claim 14
Dependent Claim
61 words
The module according to claim 1 , wherein the housing comprises a top section with a first connector, and a bottom section with a second connector, which interlocks with the first connector; wherein a first pin, defining the first axis, extends through the bottom section, the first and second connectors, and the latch for holding the latch and the housing together.
Claim 15
Dependent Claim
24 words
The module according to claim 13 , wherein the first pin has an oblong end forming a press fit connection with the bottom section.
Claim 16
Dependent Claim
40 words
The module according to claim 14 , wherein the lever is a bail having first and second side arms pivotally connected to the latch via a second pin, which extends through the latch and the first and second side arms.
Claim 17
Dependent Claim
25 words
The module according to claim 15 , wherein the second pin has an oblong end forming a press fit connection with the first side arm.
Claim 18
Dependent Claim
49 words
The module according to claim 1 , further comprising first and second projections extending from opposite sides of the housing for contacting the host receptacle to reduce electromagnetic emissions therefrom; wherein the first and second projections are vertically spaced apart, whereby adjacent modules do not have directly adjacent projections.
Claim 19
Dependent Claim
37 words
The module according to claim 17 , wherein the housing comprises an top section and a bottom section; and wherein the first projection is on the top section, and the second projection is on the bottom section.
Claim 20
Dependent Claim
33 words
The module according to claim 17 , wherein each of the first and second projections includes a ramp at a leading edge thereof to facilitate insertion of the module into the host receptacle.
Claim 21
Dependent Claim
64 words
A patch cable for electrically connecting two host devices comprising: a first electronic module in accordance with claim 1 ; a second electronic module in accordance with claim 1 ; and a multi-conductor cable having a first end fixed to the printed circuit board in the first electronic module, and a second end fixed to the printed circuit board in the second electronic module.
