Abstract
Abstract A transmission cable connector having a shell with a conductive layer thereon is contoured to place the layer a predetermined distance from the extending individual conductor wires of the cable, the contacts of the connector, the point of interconnection therebetween, and/or from the tracings on the surface of a transition board, if one is provided, all of which are provided in the transition region between the end of the cable and the contacts of the connector. The predetermined distance is determined such that when the conductive layer of the shell is connected to a predetermined potential electrical characteristics are imparted to the elements in the transition region that closely match the electrical characteristics of the cable attachable to the connector.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
166 words
In a connector of the type having a plurality of contacts, a planar substrate having an array of tracings on at least one surface thereof, the contacts being adapted to engage electrically the tracings on the substrate so that the individual tracings are connected to a respective one of the contacts as well as to a respective one of a plurality of individual conductor wires of a cable, the cable having predetermined electrical characteristics associated therewith, the connector having a shell thereon, the improvement comprising: a conductive inner layer disposed on the shell, the shell being contoured to space the conductive inner layer at a first predetermined clearance distance from the surface of the substrate such that, in use, with the inner surface of the shell connected to a predetermined electrical potential the tracings on the surface of the substrate and the conductive inner surface of the shell cooperate to impart to the tracings predetermined electrical characteristics that closely match the electrical characteristics of the cable.
Claim 2
Dependent Claim
166 words

Claim 3
Dependent Claim
20 words
The connector of claim 1 wherein the conductive inner layer is disposed in parallel to the surface of the substrate.
Claim 4
Dependent Claim
37 words
The connector of claim 2 wherein the improvement further comprises the shell being contoured to space the conductive inner layer a second predetermined clearance distance from the interconnection between the tracings and the wires of the cable.
Claim 5
Dependent Claim
37 words
The connector of claim 1 wherein the improvement further comprises the shell being contoured to space the conductive inner layer a second predetermined clearance distance from the interconnection between the tracings and the wires of the cable.
Claim 6
Dependent Claim
33 words
The connector of claim 2 wherein the improvement further comprises the shell being contoured to space the conductive inner layer a second predetermined clearance from the interconnection between the tracings and the contacts.
Claim 7
Dependent Claim
33 words
The connector of claim 1 wherein the improvement further comprises the shell being contoured to space the conductive inner layer a second predetermined clearance from the interconnection between the tracings and the contacts.
Claim 8
Dependent Claim

Claim 10
Dependent Claim
122 words
In a connector of the type having a plurality of contacts each of which is connected to an extending portion of an individual conductor wire of a cable, the cable having predetermined electrical characteristics associated therewith, the connector having a shell thereon, the improvement comprising: a conductive inner layer disposed on the shell, the shell being contoured to space the conductive layer at a predetermined clearance distance from the point of interconnection between the contacts and the extending portion of the conductors such that, in use, with the inner layer of the shell connected to a predetermined electrical potential, electrical characteristics which closely match those of the cable are imparted to the conductor wires, the contacts and the point of interconnection therebetween.
Claim 11
Dependent Claim
122 words
In a connector of the type having a plurality of contacts each of which is connected to an extending portion of an individual conductor wire of a cable, the cable having predetermined electrical characteristics associated therewith, the connector having a shell thereon, the improvement comprising: a conductive inner layer disposed on the shell, the shell being contoured to space the conductive layer at a predetermined clearance distance from the point of interconnection between the contacts and the extending portion of the conductors such that, in use, with the inner layer of the shell connected to a predetermined electrical potential, electrical characteristics which closely match those of the cable are imparted to the conductor wires, the contacts and the point of interconnection therebetween.
Claim 12
Dependent Claim
35 words
The connector of claim 9 wherein the improvement further comprises the shell being contoured to space the conductive inner layer a second predetermined clearance distance from the extending portions of the wires of the cable.
Claim 13
Dependent Claim
28 words
The connector of claim 9 wherein the improvement further comprises the shell being contoured to space the conductive inner layer a second predetermined clearance distance from the contacts.
