Abstract
Abstract Module terminals comprising a column of right angle contacts are assembled to a housing module for receiving post header terminals at one end and inserted into complimentary holes of a printed circuit board on the other end. Interposed between adjacent terminal modules are shielding members that serve to limit crosstalk between adjacent rows of contacts. The shielding members are attached to over-moulded insulative webs of the terminal module and are resiliently biased thereagainst so that they ensure good contact of an integral grounding pin with one of the right angle contacts of the terminal module and also to ensure a flush fit of the grounding shield against the terminal module.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
123 words
An electrical connector assembly comprising an insulating housing and assembled thereto a plurality of terminal modules and electrically conductive shields inserted between adjacent terminal modules, each terminal module having a plurality of contacts including a mating contact portion, a conductor connecting portion and an intermediate portion therebetween, the connector assembly characterized in that the terminal module has an insulative web that encapsulates some or all of the intermediate portion; and the electrically conductive shield has a mounting member that is engageable with a complementary mounting member of the terminal module, the shield being prestressed such that when the mounting member and the complementary mounting member are engaged, the shield is held resiliently against the terminal module due to elastic deformation of the shield.
Claim 2
Dependent Claim
123 words
An electrical connector assembly comprising an insulating housing and assembled thereto a plurality of terminal modules and electrically conductive shields inserted between adjacent terminal modules, each terminal module having a plurality of contacts including a mating contact portion, a conductor connecting portion and an intermediate portion therebetween, the connector assembly characterized in that the terminal module has an insulative web that encapsulates some or all of the intermediate portion; and the electrically conductive shield has a mounting member that is engageable with a complementary mounting member of the terminal module, the shield being prestressed such that when the mounting member and the complementary mounting member are engaged, the shield is held resiliently against the terminal module due to elastic deformation of the shield.
Claim 3
Dependent Claim
77 words
The connector of claim 1 characterized in that the shield has a substantially planar base that forms a first angle with the shield mounting member when the shield is not mounted to the terminal module, and the base can be elastically bent by an additional angle away from the mounting member such that the base forms a second angle equal to the first angle plus the additional angle when the shield is mounted to the terminal module.
Claim 4
Dependent Claim
63 words
The connector of claim 1 characterized in that the complementary mounting member is a receiving slot in the insulative web and the shield has a substantially planar base and at least one prestressed mount that can be resiliently bent for mounting in the receiving slot, such that the shield is fixedly held to the terminal module and the planar base resiliently biased thereagainst.
Claim 5
Dependent Claim
29 words
The connector of claim 1 characterized in that the shield is fixedly held to the terminal module by interference fit between the mounting member and the complementary mounting member.
Claim 6
Dependent Claim
25 words
The connector of claim 3 characterized in that the slots include protrusions, the protrusions cooperating with the mounting member to form the interference fit therebetween.
Claim 7
Dependent Claim
45 words
The connector of any one of claims 1-5 characterized in that the insulative web includes a recess and the shield is mounted substantially flush therein such that a plurality of modules can be assembled side by side with the insulative webs of adjacent modules contiguous.
