Abstract
Abstract The invention relates to a modular connector assembly which is used in stacking plural printed circuit boards in a vertical configuration. The connector housing is made up of a plurality of corrugated sheets which have been assembled side by side and spot welded together to define a honeycomb array of passages. Dielectric surrounded contacts making up contact inserts are inserted into the respective passages to provide the connector. The invention also relates to a method assembling such a connector housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
68 words
An EMI shielded interconnect for electrically connecting vertically stacked printed circuit boards, said interconnect comprising a housing having a plurality of passages extending vertically therethrough in a matrix arrangement, said housing being made up of a plurality of stamped corrugated sheets of shielding material which have been bonded to each other in an interfit manner, and each passage in said housing having a respective contact engageably received therein.
Claim 2
Dependent Claim
68 words
An EMI shielded interconnect for electrically connecting vertically stacked printed circuit boards, said interconnect comprising a housing having a plurality of passages extending vertically therethrough in a matrix arrangement, said housing being made up of a plurality of stamped corrugated sheets of shielding material which have been bonded to each other in an interfit manner, and each passage in said housing having a respective contact engageably received therein.
Claim 3
Dependent Claim
33 words
An EMI shielded interconnect as in claim 1 wherein said stamped corrugated sheets are made of stainless steel, and wherein said sheets have been at least seam welded to make up said housing.
Claim 4
Dependent Claim
53 words
An EMI shielded interconnect as in claim 2 wherein said corrugated sheets are stamped in a manner such that when assembled together to form said housing there is a projection at a predetermined location inwardly into each of said passages to define contact engaging means for retaining each contact within their respective passages.
Claim 5
Dependent Claim
49 words
An EMI shielded interconnect as in claim 2 wherein each of said contacts is arrayed as part of a contact insert assembly wherein the contact is embedded in a dielectric material extending substantially along the entire length thereof for electrically insulating each contact from the walls of said passages.
Claim 6
Dependent Claim
74 words
An EMI shielded interconnect as in claim 4 further comprising a plurality of conductive elastomeric sleeves inserted respectively in each passage surrounding each contact insert, and extending a sufficient length from top to bottom of said housing such that when said interconnect is employed to connect two printed circuit boards together, each of said conductive elastomeric sleeves abuts against the respective printed circuit boards to provide a substantially completely shielded interconnection between the boards.
Claim 7
Dependent Claim
49 words
An EMI shielded interconnect as in claim 1 wherein each of said contacts is arrayed as part of a contact insert assembly wherein the contact is embedded in a dielectric material extending substantially along the entire length thereof for electrically insulating each contact from the walls of said passages.
Claim 8
Dependent Claim
33 words
An EMI shielded interconnect as in claim 1 wherein said stamped corrugated sheets are made of stainless steel, and wherein said sheets have been at least spot welded to make up said housing.
