Abstract
Abstract A shielded transfer system is disposed on a back panel printed wiring board and has a strip body with partitions subdividing the strip body into individual rectangular chambers of equal size for receiving cable plugs having a shielding housing with a rectangular cross section. A shielding device for the cable plugs includes additional function elements disposed in the strip body for performing assigned functions, in particular for guiding, contacting, encoding and locking the cable plugs. The additional function elements are constructed and disposed for permitting the rectangular cable plugs with a plug cross section of a certain unit size and smaller rectangular cable plugs with a plug cross section being one-half and one-fourth of the plug cross section of the unit size, to be selectively inserted into the chambers of the strip body, while preserving and utilizing all of the functions of the additional function elements.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
In a shielded transfer system being disposed on a back panel printed wiring board and having a strip body with partitions subdividing said strip body into individual rectangular chambers of equal size for receiving cable plugs having a shielding housing with a rectangular cross section, a shielding device for the cable plugs, comprising additional function elements disposed in said strip body for guiding, contacting, encoding and locking the cable plugs, said additional function elements being disposed and having means for permitting the rectangular cable plugs with either a plug cross section of a certain unit size or smaller rectangular cable plugs with a plug cross section being one-half and one-fourth of the plug cross section of the unit size, to be selectively inserted into said chambers of said strip body, and said additional function elements being disposed such that all of the functions of said additional function elements are preserved and utilized regardless of whether the cable plugs of the unit size or the smaller cable plugs are inserted.
Claim 2
Dependent Claim
169 words
In a shielded transfer system being disposed on a back panel printed wiring board and having a strip body with partitions subdividing said strip body into individual rectangular chambers of equal size for receiving cable plugs having a shielding housing with a rectangular cross section, a shielding device for the cable plugs, comprising additional function elements disposed in said strip body for guiding, contacting, encoding and locking the cable plugs, said additional function elements being disposed and having means for permitting the rectangular cable plugs with either a plug cross section of a certain unit size or smaller rectangular cable plugs with a plug cross section being one-half and one-fourth of the plug cross section of the unit size, to be selectively inserted into said chambers of said strip body, and said additional function elements being disposed such that all of the functions of said additional function elements are preserved and utilized regardless of whether the cable plugs of the unit size or the smaller cable plugs are inserted.
Claim 3
Dependent Claim
41 words
The shielding device according to claim 1, wherein said additional function elements include at least one further partition subdividing at least one of said chambers of said strip body intended for receiving the smaller cable plugs into two equal-sized chamber compartments.
Claim 4
Dependent Claim
75 words
The shielding device according to claim 1, wherein said additional function elements include rectangular base plates of insulating material each being disposed in a respective one of said chambers, for contact prongs; said strip body having long sides; said base plates each having two opposed long sides with side walls spaced apart from said long sides of said strip body; and said side walls being divided in two in the middle of the length thereof.
Claim 5
Dependent Claim
29 words
The shielding device according to claim 3, wherein said side walls of said base plate have a cutout formed therein in the middle dividing said side walls in two.
Claim 6
Dependent Claim
64 words
The shielding device according to claim 3, wherein said side walls of said base plates have smooth surfaces each facing toward one of said long sides of said strip body, and said side walls of said base plate have opposed inner surfaces formed of ribs and grooves extending in a plugging direction and having an asymmetrical contour, for polarizing and encoding the cable plugs.
Claim 7
Dependent Claim
75 words
The shielding device according to claim 2, wherein said strip body has long sides facing each other and locking elements on said long sides for the cable plugs, each two of said locking elements being disposed in a respective one of said chambers of said strip body, and said locking elements being disposed symmetrically or asymmetrically with relative to one of said at least one further partition dividing said chambers into two equal-size chamber compartments.
Claim 8
Dependent Claim
38 words
The shielding device according to claim 1, wherein said strip body includes a rectangular sheet-metal frame with longitudinal plates having ends, and crosswise plates joining said longitudinal plates to one another at said ends and at equal intervals.
Claim 9
Dependent Claim
48 words
The shielding device according to claim 7, including intermediate crosswise plates each being disposed in a plane of symmetry in a respective one of said chambers provided for the smaller cable plugs, said longitudinal plates of said strip body being additionally joined together by said intermediate crosswise plates.
Claim 10
Dependent Claim
16 words
The shielding device according to claim 2, wherein each of said chambers has resilient grounding contacts.
Claim 11
Dependent Claim
17 words
The shielding device according to claim 2, wherein each of said chamber compartments has resilient grounding contacts.
Claim 12
Dependent Claim
47 words
The shielding device according to claim 7, wherein all of said longitudinal and crosswise plates of said sheet-metal frame have driving prongs being inserted into and secured in through-contacted bores formed in the printed wiring board, said bores communicating with grounding layers of the printed wiring board.
Claim 13
Dependent Claim
62 words
The shielding device according to claim 7, wherein said crosswise plates have hooks, and said longitudinal plates of said sheet-metal frame, as viewed in an upper region in a longitudinal direction, have free cuts formed therein alternating with inward-pointing spring arms extending in a plugging direction as locking elements, and webs being angled inward and having slits formed therein for said hooks.
Claim 14
Dependent Claim
87 words
The shielding device according to claim 12, including intermediate crosswise plates each being disposed in a plane of symmetry in a respective one of said chambers provided for the smaller cable plugs, said longitudinal plates of said strip body being additionally joined together by said intermediate crosswise plates, said webs of each of said longitudinal plates being formed of two half-webs for said crosswise plates, one complete middle web for said intermediate crosswise plate and two of said spring arms, for each respective one of said chambers.
Claim 15
Dependent Claim
23 words
