Abstract
Abstract A connector is provided of the type that has rows of contacts, which minimizes cross talk between adjacent contacts. An interceptor plate (60, FIG. 2) which is grounded or at another controlled potential, extends along each row of contacts (34), the plate lying close to the row to provide better capacitive coupling between each contact and the plate than between contacts of the same or different rows.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
A connector comprising: a housing having a support; first and second rows of contacts in said housing with each row of contacts including a mounted part in said support and an elongated leg extending in a predetermined forward direction from said mounted part, with the legs of the contacts in a row all lying substantially in an imaginary plane; a pair of interception plates of electrically conductive material, each interception plate lying in a plane extending parallel to a said imaginary plane of a said row of contact legs, said interception plates lying on opposite sides of the space between said first and second rows of contacts, and said interception plates each lying closer to the contacts of an adjacent row of contacts than the distance between contacts in said first and second rows, and each interception plate having at least a portion adjacent to a plurality of said contacts and at a predetermined constant potential; and wherein said housing includes insulation between the contacts of a row and on a side of each plate opposite a corresponding row of contacts, but the space between each contact leg and an adjacent interception plate is substantially devoid of insulation.
Claim 2
Dependent Claim
198 words
A connector comprising: a housing having a support; first and second rows of contacts in said housing with each row of contacts including a mounted part in said support and an elongated leg extending in a predetermined forward direction from said mounted part, with the legs of the contacts in a row all lying substantially in an imaginary plane; a pair of interception plates of electrically conductive material, each interception plate lying in a plane extending parallel to a said imaginary plane of a said row of contact legs, said interception plates lying on opposite sides of the space between said first and second rows of contacts, and said interception plates each lying closer to the contacts of an adjacent row of contacts than the distance between contacts in said first and second rows, and each interception plate having at least a portion adjacent to a plurality of said contacts and at a predetermined constant potential; and wherein said housing includes insulation between the contacts of a row and on a side of each plate opposite a corresponding row of contacts, but the space between each contact leg and an adjacent interception plate is substantially devoid of insulation.
Claim 3
Dependent Claim
183 words
A connector for connecting a pair of circuit boards lying in parallel planes, comprising: a housing having a central beam with forward and rearward ends and forward and rearward flanges at said ends, each flange forming a row of through holes at opposite sides of said beam and forming a groove extending along a face of the flange which faces the other flange; a pair of rows of contacts each having a pair of opposite mounted parts passing slideably through a hole in said front and rear flanges respectively, each contact having an elongated leg connecting said mounted parts; a pair of retainer strips that each has front and rear edges lying in the front and rear grooves on one side of said central beam and sandwiching a row of contacts between itself and the central beam; each of said retainer strips includes a strip of dielectric material adjacent to one of said rows of contacts and a strip of electrically conductive material at a predetermined constant potential on a face of said dielectric strip that is opposite the adjacent row of contacts.
Claim 4
Dependent Claim
183 words

Claim 5
Dependent Claim
42 words
The connector described in claim 2 wherein: at least one of said strips of dielectric material has a hole therein, and the corresponding strip of conductive material forms a contactor that projects through the hole and bears against one of said contacts.
