Abstract
Abstract A shielded back plane connector comprises a header assembly (2) and a daughter board connector (4). The daughter board connector in- dudes an upper and lower shield (22, 24) where the upper and lower shields (22, 24) include stamped windows (84) thereby forming passages for allowing structural ribs (32) of the housing to pass therethrough while providing a contact (82 for contact with grounding pins (48) disposed in the header assembly. A cross talk shield (100) can be positioned intermediate each of the terminal sub-assemblies (20) thereby reducing the cross talk between adjacent terminals. The shield (100) includes a contact portion for contacting the centre terminal in the shielded sub-assembly, for using the centre terminal as a ground terminal.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
An electrical connector (4) having a front housing portion (12) and a plurality of terminal subassemblies (20) fixed to said front housing portion (12), the terminal subassemblies (20) comprising a front mating contact portion (60) positioned in said front housing portion (12), an intermediate portion (62) moulded in an insulative web (58) of material, and a rear contact portion (64) extending from said web of material (58) and adapted for mating with further conductors, and a shield portion (100) positioned intermediate each said web (38), said connector (4) being characterized in that said web (58) includes a reduced thickness section therein, on both sides of said intermediate portions (62), said reduced thickness portion (102) forming a thin membrane of said insulative material over a substantial portion of said intermediate portions (62) thereby forming a pocket of air between said intermediate portions (62) and said shield portion (100), thereby increasing the impedance along the intermediate portions (62), interiorly of said shield portions (100).
Claim 2
Dependent Claim
162 words
An electrical connector (4) having a front housing portion (12) and a plurality of terminal subassemblies (20) fixed to said front housing portion (12), the terminal subassemblies (20) comprising a front mating contact portion (60) positioned in said front housing portion (12), an intermediate portion (62) moulded in an insulative web (58) of material, and a rear contact portion (64) extending from said web of material (58) and adapted for mating with further conductors, and a shield portion (100) positioned intermediate each said web (38), said connector (4) being characterized in that said web (58) includes a reduced thickness section therein, on both sides of said intermediate portions (62), said reduced thickness portion (102) forming a thin membrane of said insulative material over a substantial portion of said intermediate portions (62) thereby forming a pocket of air between said intermediate portions (62) and said shield portion (100), thereby increasing the impedance along the intermediate portions (62), interiorly of said shield portions (100).
Claim 3
Dependent Claim
48 words
An electrical connector (4) of claim 1, characterized in that, said web (58) includes a window (106) therethrough exposing one of said intermediate portions (62) of one select terminal (56c), and said shield portion (100) includes a resilient contact portion (126) for contacting said selected intermediate portion (62).
Claim 4
Dependent Claim
34 words
An electrical connector (4) of any of claims 1-2, characterized in that said resilient contact portion (126) is formed from a reversely bent contact leg (124) which extends integrally from said shield portion (100).
Claim 5
Dependent Claim
26 words
An electrical connector (4) of any of claims 1-3, characterized in that the resilient contact portion (126) is formed-by a portion extending from one edge thereof.
Claim 6
Dependent Claim
24 words
An electrical connector (4) of any of claims 1-4, characterized in that said connector includes five electrical terminals (56) positioned in said subassemblies (20).
Claim 7
Dependent Claim
38 words
An electrical connector (4) of any of claims 1-5, characterized in that said terminals (56) are arranged in two pairs of signal contacts with the intermediate contact (56c) being said selected one, to ground said shield portion (100).
Claim 8
Dependent Claim
64 words
An electrical connector (4) according to any one of claims 1-6, characterized in that said connector (4) is profiled as a right angled connector where said rear mating contact portions (64) extend from said web (58) at a substantial right angle relative to said front mating contact portions (60), said webs (58) including a lower edge profiled for receiving a printed circuit board thereagainst.
Claim 9
Dependent Claim
38 words
An electrical connector (4) according to claim 7, characterized in that said shield portion (100) includes a second resilient contact portion (122) extending below said web lower edge, for contacting a ground plate on said printed circuit board.
Claim 10
Dependent Claim
41 words
An electrical connector (4) according to any one of claims 1-8, characterized in that said shield portion (100) includes two resilient contact arms (122) extending from a lower edge thereof, profiled to contact a grounding pad on a printed circuit board.
Claim 11
Dependent Claim
140 words
An electrical connector (4) having a front housing portion (12) and a plurality of contact modules (20) fixed to said front housing portion (12), the contact modules (20) comprising a front mating contact portion (60) positioned in said front housing portion (12), an intermediate portion (62) moulded in an insulative web (58) of material, and a rear contact portion (64) extending from said web (58) of material and adapted for mating with further conductors, and a shield member (100) positioned intermediate each said web (58), said connector (4) being characterized in that said web (58) includes a recessed surface (104) profiled for receiving the shield member (100) thereagainst whereby a plurality of contact modules (20) may be stacked one against the other, with or without a shield member (100) therebetween, and the stacking thickness of the modules (20) remains constant.
