Abstract
Abstract A small form-factor pluggable metal cage has two sidewalls, a sidewall cover, a top plate, a soleplate and rear cover, which are made of a single piece of metal plate. Two types of legs extend from the cage, one being compliant type for extending through the board holes defined in a printed circuit board (PCB) and the other being piggy type abutting against the board. The compliant legs define two arc sections for stability and preventing the cage from disengaging from the PCB during the course of reflowing. The rear cover includes an inner panel extending from the second sidewall with a tab formed on a free end to engage a notch defined in the first sidewall. An outer panel extends from the top plate. The outer panel defines a slot for engaging a clasp of the inner panel. Two patches respectively extend from the sidewalls and are located above the inner panel.

Claim 1
Independent Claim
107 words
A small form-factor pluggable transceiver cage comprising: a top plate; a soleplate; a rear cover comprising an inner panel and an outer panel; a sidewall cover and two sidewalls, whereby the cage being made of a single piece of blank metallic material; wherein the inner panel extends from the second sidewall having a free end opposite the second sidewall, the outer panel extending from the top plate; and wherein two types of legs extending out of the lower edge of the sidewalls, one being compliant leg adapted to extent through a printed circuit board, and the other being piggy leg adapted to abut against printed circuit board.
Claim 2
Dependent Claim
107 words
A small form-factor pluggable transceiver cage comprising: a top plate; a soleplate; a rear cover comprising an inner panel and an outer panel; a sidewall cover and two sidewalls, whereby the cage being made of a single piece of blank metallic material; wherein the inner panel extends from the second sidewall having a free end opposite the second sidewall, the outer panel extending from the top plate; and wherein two types of legs extending out of the lower edge of the sidewalls, one being compliant leg adapted to extent through a printed circuit board, and the other being piggy leg adapted to abut against printed circuit board.
Claim 3
Dependent Claim
39 words
The cage as described in claim 1 , wherein at least one of the compliant legs comprises first and second arc portions, the curvature of the first arc portion being greater than the curvature of the second arc portion.
Claim 4
Dependent Claim
27 words
The cage as described in claim 2 , wherein the second arc portions of the compliant legs being selectively bent toward or away from the rear cover.
Claim 5
Dependent Claim
127 words
A one-piece small form pluggable transceiver metal cage comprising: a top plate; a soleplate; a rear cover structure; a sidewall cover; first sidewall and second sidewall, wherein the rear cover structure comprises an inner panel and an outer panel and two bulge patches for grounding; wherein the inner panel extends from the second sidewall having a free end opposite the second sidewall, the outer panel extending from the top plate; wherein the first sidewall defines a notch in a rear edge thereof, a projection extending from the free end of the inner panel engaging the notch to fix the inner panel to the first sidewall; and wherein the inner panel forms a resilient clasp and the outer panel defines a rectangular hole for engaging the resilient clasp.
Claim 6
Dependent Claim
127 words
A one-piece small form pluggable transceiver metal cage comprising: a top plate; a soleplate; a rear cover structure; a sidewall cover; first sidewall and second sidewall, wherein the rear cover structure comprises an inner panel and an outer panel and two bulge patches for grounding; wherein the inner panel extends from the second sidewall having a free end opposite the second sidewall, the outer panel extending from the top plate; wherein the first sidewall defines a notch in a rear edge thereof, a projection extending from the free end of the inner panel engaging the notch to fix the inner panel to the first sidewall; and wherein the inner panel forms a resilient clasp and the outer panel defines a rectangular hole for engaging the resilient clasp.
Claim 7
Dependent Claim
23 words
The cage as described in claim 4 , wherein the inner panel forms a plurality of legs extending from a lower edge thereof.
Claim 8
Dependent Claim
157 words
A one-piece pluggable transceiver metal cage comprising: a top plate; a soleplate opposite to said top plate in a parallel relation therebetween; first and second mutually parallel sidewalls positioned between said top plate and said soleplate, said first sidewall integrally connected to both said top plate and said soleplate while said second sidewall integrally connected only to the soleplate; a sidewall cover downwardly extending from one edge of said top plate and at least partially overlapping said second sidewall; and a rear cover including inner and outer panels, said inner panel laterally integrally extending from a rear edge of one of said first and second sidewalls toward the other of said first and second sidewalls, and at a distal free end of said inner panel abutting against said other of said first and second sidewalls, said outer panel downwardly integrally extending from a rear edge of said top plate and at least partially overlapping said inner panel.
Claim 9
Dependent Claim
157 words
A one-piece pluggable transceiver metal cage comprising: a top plate; a soleplate opposite to said top plate in a parallel relation therebetween; first and second mutually parallel sidewalls positioned between said top plate and said soleplate, said first sidewall integrally connected to both said top plate and said soleplate while said second sidewall integrally connected only to the soleplate; a sidewall cover downwardly extending from one edge of said top plate and at least partially overlapping said second sidewall; and a rear cover including inner and outer panels, said inner panel laterally integrally extending from a rear edge of one of said first and second sidewalls toward the other of said first and second sidewalls, and at a distal free end of said inner panel abutting against said other of said first and second sidewalls, said outer panel downwardly integrally extending from a rear edge of said top plate and at least partially overlapping said inner panel.
Claim 10
Dependent Claim
34 words
