Abstract

Abstract A connector is provided of the type that has rows of contacts, which minimizes crosstalk between adjacent contacts. An interceptor plate which is grounded or at another controlled potential, extends along each row of contacts, 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. The space between each contact leg and an adjacent interceptor plate, contains a dielectric whose dielectric constant varies by no more than four per cent between 1 kHz and 100 MHz. The capacitance between each contact and an adjacent interception plate is at least three times the capacitance between adjacent contacts of a row.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 184 words
A connector comprising an insulative support, a plurality of contacts arranged in a row with each contact including a mounted part in said support and an elongated leg extending primarily in a predetermined forward direction from the mounted part, with the legs of the contacts in the row lying substantially in an imaginary plane and an interception plate of electrically conductive material lying in a plane extending parallel to the imaginary plane of the row, the interception plate lying a distance J from the contacts of the row of contacts, the contacts in the row being spaced apart by a distance D, and the interception plate having at least a portion adjacent to a plurality of the contacts and at a predetermined potential, characterised in that the space between each contact leg and adjacent interception plate is filled with a dielectric having a dielectric constant that varies by less than four per cent between 1 kHz and 100 MHz and the capacitance between each of the contacts and the interception plate, is at least three times the capacitance between adjacent contacts of the row.
Claim 2
Dependent Claim 184 words
A connector comprising an insulative support, a plurality of contacts arranged in a row with each contact including a mounted part in said support and an elongated leg extending primarily in a predetermined forward direction from the mounted part, with the legs of the contacts in the row lying substantially in an imaginary plane and an interception plate of electrically conductive material lying in a plane extending parallel to the imaginary plane of the row, the interception plate lying a distance J from the contacts of the row of contacts, the contacts in the row being spaced apart by a distance D, and the interception plate having at least a portion adjacent to a plurality of the contacts and at a predetermined potential, characterised in that the space between each contact leg and adjacent interception plate is filled with a dielectric having a dielectric constant that varies by less than four per cent between 1 kHz and 100 MHz and the capacitance between each of the contacts and the interception plate, is at least three times the capacitance between adjacent contacts of the row.

Dependent Claim 16 words
A connector as claimed in claim 1, characterised in that the dielectric includes solid dielectric material.
Claim 4
Dependent Claim 37 words
A connector as claimed in claim 1 or claim 2, characterised in that the capacitance between each of the contacts and the interception plate is at least six times the capacitance between adjacent contacts of the row.
Claim 5
Dependent Claim 44 words
A connector as claimed in any preceding claim, characterised in that the dielectric which fills the space between each contact leg and the adjacent interception plate has a dielectric constant that varies by less than two per cent between 1 kHz and 100 MHz.
Claim 6
Dependent Claim 32 words
A connector as claimed in any preceding claim, characterised in that more than half of the dielectric which fills the space between each contact leg and the adjacent interception plate, is air.
