Abstract
Abstract A filter electrical connector comprises a dielectric housing (12), a metal shield case (13) covering the outside of the housing (12), aligned holes (21, 24) in rear walls (18, 19) of the housing (12) and the case (13), capacitors (14) secured in the holes (24) of wall (19) of case (13) and disposed in larger sections (22) of holes (21) in wall (18) of housing (12) without engaging the walls thereof, and electrical contacts (15) having contact sections (15a) extending through the capacitors (14) and extending through smaller sections (23) of the holes (21) without engaging the walls thereof and into housing (12). Post sections (15b) of the contacts (15) extend exteriorly from the rear wall (19) of case (13) and extend through apertures (26) of an inductor (16).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
An electrical connector, comprising: a dielectric housing having a dielectric rear wall through which holes extend, each said hole opening into a recess in said rear wall; a metal shield case covering the outside of said housing; a metal rear wall extending along the dielectric rear wall and having openings in alignment with the respective holes in said dielectric rear wall; capacitors secured in said openings in said metal rear wall in electrical connection therewith with a section of each capacitor being disposed in said recess without engaging the walls of said recess; and electrical contacts having contact sections extending through the capacitors in electrical connection therewith and extending through the respective holes in the dielectric rear wall without engaging the walls of said holes and into said housing.
Claim 2
Dependent Claim
129 words
An electrical connector, comprising: a dielectric housing having a dielectric rear wall through which holes extend, each said hole opening into a recess in said rear wall; a metal shield case covering the outside of said housing; a metal rear wall extending along the dielectric rear wall and having openings in alignment with the respective holes in said dielectric rear wall; capacitors secured in said openings in said metal rear wall in electrical connection therewith with a section of each capacitor being disposed in said recess without engaging the walls of said recess; and electrical contacts having contact sections extending through the capacitors in electrical connection therewith and extending through the respective holes in the dielectric rear wall without engaging the walls of said holes and into said housing.
Claim 3
Dependent Claim
21 words
An electrical connector as claimed in claim 1, wherein said rear walls are in engagement or closely adjacent to each other.
Claim 4
Dependent Claim
28 words
An electrical connector as claimed in claim 1, wherein said contacts have post sections extending exteriorly of the metal rear wall and through apertures in an inductor member.
Claim 5
Dependent Claim
44 words
An electrical connector as claimed in claim 1, wherein a reinforcement member is mounted on said metal rear wall and having further openings in alignment with the respective openings of said metal rear wall with ends of said capacitors disposed in said further openings.
Claim 6
Dependent Claim
21 words
An electrical connector as claimed in claim 4, wherein the contact sections adjacent said ends of said capacitors have neck sections.
