Abstract
Abstract The housing of the cable plug is exclusively formed of a one-piece metal part bent U-shaped which presses against the unit equipped with the contact spring elements under spring tension. In order for a shielding elimination to ensue on a short, direct path to a grounded potential carrier, the legs of the metal part nearly surround the unit or they even extend beyond it. In such a case, they are executed as resilient tongues with which an electrical connection to the grounded potential carrier directly ensues. Catch elements are provided for an interlocking connection of the metal part to the unit containing the spring clips or the blade strips. The web surface of the metal part proceeds at a slant relative to the bottom edges of its legs. In order to enable an oblique exit of the cable both toward the top and bottom, as well as toward the right and left, the said unit can also be engaged side-inverted without loss of positioning.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
151 words
A cable plug for accepting an end of a shielded cable comprising a unit equipped with contact elements and a housing co-utilized for shielding and rigidly connected to said unit comprising: said housing being formed by a single-piece metal part bent U-shaped comprising two legs and a web surface, said metal part, under spring tension, pressing against the unit equipped with contact elements, surrounding said unit such that said legs of the metal part extend at least close to the edge of the unit such that a space serving for the acceptance of the cable end arises between the web surface of the metal part and a back end face of the unit; said metal part comprising a catch element which, after the metal part has been shaped onto said unit, interlocks with a corresponding catch element of the unit; said legs producing an electrical connection to a grounded potential carrier.
Claim 2
Dependent Claim
151 words
A cable plug for accepting an end of a shielded cable comprising a unit equipped with contact elements and a housing co-utilized for shielding and rigidly connected to said unit comprising: said housing being formed by a single-piece metal part bent U-shaped comprising two legs and a web surface, said metal part, under spring tension, pressing against the unit equipped with contact elements, surrounding said unit such that said legs of the metal part extend at least close to the edge of the unit such that a space serving for the acceptance of the cable end arises between the web surface of the metal part and a back end face of the unit; said metal part comprising a catch element which, after the metal part has been shaped onto said unit, interlocks with a corresponding catch element of the unit; said legs producing an electrical connection to a grounded potential carrier.
Claim 3
Dependent Claim
32 words
A cable plug according to claim 1, wherein said cable plug is rectangular and comprises a pair of broad sides and narrow sides and said legs embrace surfaces on the broad sides.
Claim 4
Dependent Claim
34 words
A cable plug according to claim 1, further comprising a centering unit for accepting and guiding said cable plug, including a grounded metallic element to be contacted by the legs of the metal part.
Claim 5
Dependent Claim
42 words
A cable plug according to claim 1, wherein said legs extend beyond the edge of said unit on both sides and are formed as preformed resilient parts such that immediately after a plug-in event, a contacting to said grounded potential carrier occurs.
Claim 6
Dependent Claim
54 words
A cable plug according to claim 4, wherein each resilient part is divided into two and arched toward the contacting location, so that the cut-out edges of a cut-out in a grounded shielding plate used as the grounded potential carrier can be contacted, said cut-out being present for passage to the respective cooperating contacts.
Claim 7
Dependent Claim
67 words
A cable plug according to claim 4, wherein each resilient part is slotted and each part, during plugging, is introducable in laterally contacting fashion in a corresponding, lateral expansion of a cut-out of a shielding plate used as grounded potential carrier when the cable plug is plugged in; and in that the outer edge of every part fashioned as a catch nose engages behind this shielding plate.
Claim 8
Dependent Claim
66 words
A cable plug according to claim 1, wherein catch elements are present on every side of the unit surrounded by the legs of the metal part, said catch elements being arranged symmetrically relative to a symmetry axis of the unit proceeding in a slide-on direction, so that the metal part can be alternately slipped on in two positions offset relative to one another by 180 degrees.
Claim 9
Dependent Claim
34 words
A cable plug according to claim 7, wherein the catch element of the metal part represents a corresponding cutout and the catch element respectively corresponding thereto and engaging into this cut-out represents an elevation.
Claim 10
Dependent Claim
30 words
A cable plug according to claim 1, wherein the web surface of the U-shaped metal part proceeds at a defined angle relative to the lower edge of the cable plug.
Claim 11
Dependent Claim
24 words
A cable plug according to claim 1, wherein the web surface is formed by at least three surface parts angled relative to one another.
Claim 12
Dependent Claim
20 words
A cable plug according to claim 10, wherein said surface parts comprise openings for the acceptance of additional function elements.
Claim 13
Dependent Claim
44 words
A cable plug according to claim 1, wherein the side edges of the U-shaped metal part are at least partly expanded to form a clip bent inward approximately perpendicular to the leg, so that grounding springs additionally to be applied thereto, can be contacted.
