Abstract
Abstract A cable plug enclosed by a shielding housing can be plugged onto a plug connector of a backplane printed circuit board. The shielding housing can make contact with shielding metal sheets arranged along the long sides of the plug connector. The shielding metal sheets are extended beyond the contact-making region and form guiding sections into which are cut, starting from the top edge, guiding slots for hook-like guiding lugs of the shielding housing (11). The shielding metal sheets, the guiding slots and the guiding lugs engage around one another alternately in such a way that the cable plug is held on the backplane printed circuit board in an approximately rigid manner.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
In a device for holding a shielded cable plug on a plug connector on a backplane wiring of a mounting rack, the device having shielding metal sheets along side walls of a plug housing of the plug connector with spring tongues, which can make contact with a shielding housing enclosing the cable plug, and the shielding metal sheets being extended beyond the contact-making region to form guiding sections which bear against the shielding housing of the cable plug, the improvement comprising guiding slots, which are open toward the outside and extend in the insertion direction, being cut into the guiding sections, the shielding housing of the cable plug having protruding guiding webs which engage with little play into the guiding slots, and the shielding housing being provided with hook-like projections which engage around the shielding metal sheets.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
46 words
In a device according to claim 1, wherein the hook-like projections are fitted directly on the guiding webs to form hook-like guiding lugs, and wherein the distance between the hook-like projections and the shielding housing is approximately equal to the thickness of the shielding metal sheet.
Claim 4
Dependent Claim
57 words
In a device according to claim 2, wherein the hook-like guiding lugs are bent out from a metal lamina fixed to the inner wall of the shielding housing which has slot-like apertures for the guiding lugs, and in that the width of each of the slot-like apertures is approximately equal to the thickness of the metal lamina.
Claim 5
Dependent Claim
41 words
In a device according to claim 3, which includes latching lugs being bent from the metal lamina, said latching lugs projecting through additional slot-like apertures in the shielding housing and into perforations in the guiding sections of the shielding metal sheets.
Claim 6
Dependent Claim
39 words
In a device according to claim 4, wherein open longitudinal slots, which extend in the insertion direction, are formed in the shielding metal sheets between the guiding slots for the guiding lugs and the perforations for the latching lugs.
Claim 7
Dependent Claim
39 words
In a device according to claim 2, wherein the guiding web and the hook-like projection lie in one plane, and the hook-like projection projects over the guiding web in the insertion direction beyond the end of the guiding slot.
Claim 8
Dependent Claim
57 words
In a device according to claim 6, wherein the hook-like guiding lugs are bent out from a metal lamina fixed to the inner wall of the shielding housing, which has slot-like apertures for the guiding lugs, and in that the width of each of the slot-like apertures is approximately equal to the thickness of the metal lamina.
Claim 9
Dependent Claim
41 words
In a device according to claim 7, which includes latching lugs being bent from the metal lamina, said latching lugs projecting through additional slot-like apertures in the shielding housing and into perforations in the guiding sections of the shielding metal sheets.
Claim 10
Dependent Claim
36 words
In a device according to claim 8, wherein the shielding metal sheets have open longitudinal slots extending in the insertion direction between the guiding slots for the guiding lugs and the perforations for the latching lugs.
