Abstract
Abstract A shielded electrical connector comprises a housing having contact sections of electrical contact members disposed in passages of the housing and exposed terminal sections extending outwardly and downwardly from a rear surface of the housing for electrical connection with signal paths of a printed circuit board. A shield plate extends along a row of terminal sections and has ground terminals electrically connected to ground tabs of contact members and ground terminals for electrical connection with ground paths of the printed circuit board.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
A shielded electrical connector, comprising: a dielectric housing having rows of contact-receiving passages extending therethrough; a plurality of electrical contact members having contact sections disposed in said contact-receiving passages and exposed terminal sections extending outwardly in rows from a rear surface of said housing for electrical engagement with signal paths of a printed circuit board; a shield plate having an insulation layer covering the exterior surfaces thereof and disposed along one of said rows of terminal sections to eliminate noise faults between and among certain contact sections, where selected said contact members of said one row include ground tabs, said shield plate including along an upper edge thereof ground terminals each aligned with and connected to a said ground tab, and at the lower end thereof a like plurality of ground terminals aligned with and electrically connected to a said ground path of said printed circuit board, whereby said selected contact members are isolated from the remaining contact members of said shielded electrical connector such that noise faults are eliminated between said remaining contact members in said one row.
Claim 2
Dependent Claim
179 words
A shielded electrical connector, comprising: a dielectric housing having rows of contact-receiving passages extending therethrough; a plurality of electrical contact members having contact sections disposed in said contact-receiving passages and exposed terminal sections extending outwardly in rows from a rear surface of said housing for electrical engagement with signal paths of a printed circuit board; a shield plate having an insulation layer covering the exterior surfaces thereof and disposed along one of said rows of terminal sections to eliminate noise faults between and among certain contact sections, where selected said contact members of said one row include ground tabs, said shield plate including along an upper edge thereof ground terminals each aligned with and connected to a said ground tab, and at the lower end thereof a like plurality of ground terminals aligned with and electrically connected to a said ground path of said printed circuit board, whereby said selected contact members are isolated from the remaining contact members of said shielded electrical connector such that noise faults are eliminated between said remaining contact members in said one row.
Claim 3
Dependent Claim
26 words
A shielded electrical connector as claimed in claim 1, wherein said ground tabs comprise opposed arcuate ground terminal sections between which said ground tabs are disposed.
Claim 4
Dependent Claim
34 words
A shielded electrical connector as claimed in claim 1, wherein said terminal sections are bent forming slanted portions that extend downwardly and linear portions that extend parallel to said rear surface of said housing.
Claim 5
Dependent Claim
23 words
A shielded electrical connector as claimed in claim 1, wherein the terminal sections are disposed in a retaining plate holding them in place.
