Abstract
Abstract A stiffener device for use with electrical connectors. More particularly, the stiffener device includes a rigid L-shaped member having a groove in which an electrical connector is slidingly received and locking clips which are attached to the connector and frictionally received in a channel in the L-shaped member to prevent relative movement between the member and connector.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
An improvement to an elongated, rigid stiffener device for being attached to and used to prevent bowing of electrical connectors of the type having conductive leads extending outwardly therefrom for electrical engagement with printed circuit cards, said improvement comprising: an outwardly open channel extending along one free edge of the stiffener device; means to removably attach said stiffener device to both at least one electrical connector and a printed circuit card electrically engaged to said at least one electrical connector; and locking clips having plate means at one end for being attached to a connector and a spring section at another end for being frictionally received in said channel to prevent relative movement between the connector and the stiffener device.
Claim 2
Dependent Claim
120 words
An improvement to an elongated, rigid stiffener device for being attached to and used to prevent bowing of electrical connectors of the type having conductive leads extending outwardly therefrom for electrical engagement with printed circuit cards, said improvement comprising: an outwardly open channel extending along one free edge of the stiffener device; means to removably attach said stiffener device to both at least one electrical connector and a printed circuit card electrically engaged to said at least one electrical connector; and locking clips having plate means at one end for being attached to a connector and a spring section at another end for being frictionally received in said channel to prevent relative movement between the connector and the stiffener device.
Claim 3
Dependent Claim
15 words
The improvement of claim 1 wherein said spring section is offset from said plate means.
Claim 4
Dependent Claim
34 words
The improvement of claim 2 wherein said spring section includes a pair of arcuate-shaped spring portions having convex surfaces and with respective said convex surfaces facing outwardly in opposite directions relative to each other.
Claim 5
Dependent Claim
106 words
A stiffener device used to prevent bowing of electrical connectors of the type having conductive leads extending outwardly from a dielectric housing for electrical engagement with printed circuit cards, said stiffener device comprising: an elongated, rigid, L-shaped member having an outwardly open channel along a free edge of and means for receiving one or more connectors on one leg and means for receiving spacer means on another leg; and locking clips having means for being attached to the connector at one end and a spring section at another end for being frictionally received in said channel to prevent relative movement between the connector and rigid member.
Claim 6
Dependent Claim
106 words
A stiffener device used to prevent bowing of electrical connectors of the type having conductive leads extending outwardly from a dielectric housing for electrical engagement with printed circuit cards, said stiffener device comprising: an elongated, rigid, L-shaped member having an outwardly open channel along a free edge of and means for receiving one or more connectors on one leg and means for receiving spacer means on another leg; and locking clips having means for being attached to the connector at one end and a spring section at another end for being frictionally received in said channel to prevent relative movement between the connector and rigid member.
Claim 7
Dependent Claim
44 words
The device of claim 4 wherein said spring section includes a plurality of arcuate-shaped spring portions having outwardly facing convex surfaces for frictionally engaging said channel and with at least two of said convex surfaces facing outwardly in opposite directions relative to each other.
Claim 8
Dependent Claim
17 words
The device of claim 5 wherein said means for being attached to the connection include a plate.
Claim 9
Dependent Claim
17 words
The device of claim 6 wherein said spring section is offset from the plane of said plate.
