Abstract
Abstract A modular electrical component packaging system which utilizes a plurality of identical structural elements is disclosed. The system incorporates one or more generally rectangular card cages for receiving and retaining printed circuit boards, power supplies, ventilation fans etc. Welded onto, bolted to, formed integrally on, or attached separately to two opposed sides of each rectangular card cage are a pair of identical vertically oriented channel members which serve to provide vertical support and to enclose a lock mechanism. A plurality of identical exterior panel members is provided, each including a planar surface and a pair of generally perpendicular side walls having mounting pins for coupling each exterior panel member to a pair of vertical channel members. Each exterior panel member thus overlies an entire side of the generally rectangular card cage and a portion of each side of the card cage having a vertical channel member mounted thereon. The lock mechanism within each vertical channel member serves to selectively engage the mounting pins, thereby securing each exterior panel member in place. In this manner, each card cage within a stacked modular system requires two identical vertical channel members and two identical exterior panel members, thereby minimizing the number of distinct structural elements which must be provided for the packaging system.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
A modular packaging system for electrical components comprising: at least one generally rectangular card cage having two pairs of opposed vertical side panels for receiving and retaining electrical components therein. two substantially identical channel members each disposed vertically and generally centrally located on one of a first pair of opposed vertical side panels; two substantially identical exterior panel members, each having a first planar surface for overlying an entire one of a second pair of opposed vertical side panels and having a pair of planar side surfaces integral with and generally perpendicular to said first planar surface each overlying at least a portion of one of said first pair of opposed vertical side panels; and means for coupling each of said two substantially identical exterior panel members to both of said two substantially identical channel members.
Claim 2
Dependent Claim
136 words
A modular packaging system for electrical components comprising: at least one generally rectangular card cage having two pairs of opposed vertical side panels for receiving and retaining electrical components therein. two substantially identical channel members each disposed vertically and generally centrally located on one of a first pair of opposed vertical side panels; two substantially identical exterior panel members, each having a first planar surface for overlying an entire one of a second pair of opposed vertical side panels and having a pair of planar side surfaces integral with and generally perpendicular to said first planar surface each overlying at least a portion of one of said first pair of opposed vertical side panels; and means for coupling each of said two substantially identical exterior panel members to both of said two substantially identical channel members.
Claim 3
Dependent Claim
29 words
The modular packaging system for electrical components according to claim 1 further including a top panel for overlying the top of said at least one generally rectangular card cage.
Claim 4
Dependent Claim
27 words
The modular packaging system for electrical components according to claim 2 further including means coupling said top panel to both of said two substantially identical channel members.
Claim 5
Dependent Claim
71 words
The modular packaging system for electrical components according to claim 1 wherein said means for coupling each of said two substantially identical exterior panel members to both of said two substantially identical channel members comprises at least one mounting pin disposed on each of said pair of planar side surfaces and a corresponding aperture within each of said two substantially identical channel members for receiving said at least one mounting pin.
Claim 6
Dependent Claim
28 words
