Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
In a card edge connector having a housing providing a vertically recessed card receiving cavity and rows of resilient electrical contacts along opposite sides of said cavity, with walls of said housing defining individual channels for containing said contacts, and with webs of said housing bridging across said channels and deflecting free ends of said contacts away from the mouth of said cavity and into said channels, the improvement comprising: a snap on card guide having a first leg engaging the external wall of said housing and a second leg having a top wall, overlying at least one of said webs and inclined toward a mouth of said cavity, and an end wall aligned with said mouth to support a card received by said cavity, a set of jaws integral with said first leg and having a restricted width clearance therebetween wedgingly receiving a partition wall therein, each jaw having a hook portion received over said housing external wall and partially entering one of said channels.
Claim 2
Dependent Claim
166 words

Claim 3
Dependent Claim
35 words
The structure as recited in claim 1, and further including: horizontal lips defined on said housing external wall where said channels project through said wall, each said hook portion being received over one said lip.
Claim 4
Dependent Claim
35 words
The structure as recited in claim 1, wherein, said jaws are molded with projections facing into said clearance between said jaws and adapted for engaging opposite sides of a partition wall received between said jaws.
Claim 5
Dependent Claim
40 words
The structure as recited in claim 3, wherein, said second leg overlies both said jaws and is bifurcated by an opening in alignment with said clearance, so that said projections on said jaws may be molded integral with said jaws.
Claim 6
Dependent Claim
112 words
A card guide adapted for snap on mounting to a card edge connector provided with a card receiving cavity and electrical contacts mounted in channels along opposite sides of said cavity, comprising: a first leg adapted for engaging an external wall of said connector, a second leg adapted to overlie said connector and having a card supporting surface adapted to engage and support a card during insertion into said card edge connector, and a pair of jaws on said first leg adapted to enter selected ones of said channels, said jaws resiliently engaging therebetween a wall separating said selected channels, said jaws having hook portions hooked over lip sections of said wall.
Claim 7
Dependent Claim
112 words
A card guide adapted for snap on mounting to a card edge connector provided with a card receiving cavity and electrical contacts mounted in channels along opposite sides of said cavity, comprising: a first leg adapted for engaging an external wall of said connector, a second leg adapted to overlie said connector and having a card supporting surface adapted to engage and support a card during insertion into said card edge connector, and a pair of jaws on said first leg adapted to enter selected ones of said channels, said jaws resiliently engaging therebetween a wall separating said selected channels, said jaws having hook portions hooked over lip sections of said wall.
Claim 8
Dependent Claim
22 words
The structure as recited in claim 5, wherein, said lip sections are defined at the intersections of said channels with said wall.
Claim 9
Dependent Claim
