Abstract

Abstract A capacitor array for filter connectors includes a stamped and formed ground resilient metal plate. Integral tines are provided to establish a solderless electrical connection between the plate and a connector shell. The filter elements are discoidal capacitors having cylindrical inner and outer electrode portions. The filter assembly is completed by soldering the outer electrode portions to the ground plate, while a solderless electrical connection between the inner electrodes and the feedthrough contacts of a connector is established by providing compliant sections on the contacts. A pi filter array is formed using two of the ground plates.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 110 words
A filter assembly for an electrical connector, comprising: a ground plate of resilient conductive material including means defining a plurality of apertures in said plate; grounding means for electrically connecting said plate to the shell of a connector; at least one discoidal filter element which includes an inner electrode defining a central aperture of said filter element, and an outer electrode; and ground electrode connection means for electrically connecting said outer electrode to said surface of plate, characterized in that said discoidal filter element is arranged on a surface of said plate such that a principal axis of said filter element extends through a center of one of said apertures.
Claim 2
Dependent Claim 50 words
A filter assembly as claimed in claim 1, characterized in that said ground plate is stamped and formed and said grounding means comprises a plurality of tines extend radially outwardly from a periphery of said plate and at an oblique angle in respect to a principal plane of said plate.
Claim 3
Dependent Claim 57 words
A filter assembly as claimed in claim 2, characterized in that a distance between diametrically opposite ones of peripheral ends of said tines is greater than an interior diameter of a connector into which said filter assembly is to be inserted, thereby causing said tines to be deflected inwardly upon insertion of the assembly into the connector.
Claim 4
Dependent Claim 128 words
An electrical connector, comprising a filter assembly as claimed in claim 1, further characterized in that it includes a shell, and in that said grounding means includes a plurality of tines extending radially outwardly from the periphery of the plate for establishing an electrical connection between said plate and said shell, said tines having principal axes extending at an oblique angle in respect to a principal plane of said plate; and further characterized in that said discoidal filter element comprises a substantially cylindrical central aperture and a substantially cylindrical outer perimeter, a diameter of said central aperture being smaller than a diameter of said one of said plate aperture, and a diameter of said outer perimeters being larger than said diameter of said one of said plate apertures.
Claim 5
Dependent Claim 37 words
A filter assembly as claimed in claims 1 or 4, characterized in that said filter element is a capacitor and said outer electrode substantially surrounds said capacitor, whereby said outer electrode serves to electrically isolate said capacitor.
Claim 6
Dependent Claim 62 words
A connector as claimed in claims 1 or 4, characterized in that said discoidal filter element comprises a cylindrical inner electrode defining a central aperture, and an outer electrode which includes a circumferential outer electrode portion surrounding said filter element, and wherein said outer electrode portion is soldered to a planar surface of said plate on which said filter element is positioned.
Claim 7
Dependent Claim 18 words
A filter assembly as claimed in claims 1 or 4, characterized in that said material is phosphor bronze.
Claim 8
Dependent Claim 18 words
A filter assembly as claimed in claims 1 or 4, characterized in that said material is beryllium copper.
Claim 9
Dependent Claim 72 words
A connector as claimed in claim 4, characterized in that said connector comprises a plurality of feedthrough contacts arranged to pass through said apertures, at least one of said contacts comprising resilient means for resiliently engaging said inner electrode of said filter element to thereby establish an electrical connection between said at least one contact and said inner electrode, and to removably hold said contact in said aperture of said filter element.
Claim 10
Dependent Claim 23 words
A connector as claimed in claim 9, characterized in that said resilient means comprise a compliant section on said one of said contacts.
Claim 11
Dependent Claim 171 words
A connector as claimed in claim 9, characterized by further comprising an inductor sleeve surrounding said at least one of said contacts, and a second stamped and formed metal plate of resilient conductive material including means defining a plurality of second apertures in said plate and a plurality of second tines extending radially outward from the periphery of the plate, said second tines extending at an oblique angle in respect to a principal plane of said second plate; and at least one second discoidal filter element arranged on said second plate such that a principal axis of said filter element extends through a center of one of said second apertures, wherein said second discoidal filter element comprises a substantially cylindrical second central aperture and a substantially cylindrical second outer perimeter, a diameter of said second central aperture being smaller than a diameter of said one of said second plate apertures, and a diameter of said second outer perimeter being larger than said diameter of said one of said second plate apertures.
Claim 12
Independent Claim 113 words
A method of assembling a connector filter assembly, comprising the steps of stamping and forming a metal plate to obtain a stamped and formed metal plate including a plurality of plate apertures and a plurality of resilient tines extending about the periphery of said plate, and bending said tines to extend at an oblique angle in respect to a principal plane of said plate, and characterized by further comprising the steps of: aligning a cylindrical aperture of at least one discoidal filter element with one of said plate apertures; and electrically connecting an outer electrode portion of said filter element to a surface of said plate on which said filter element is positioned.
Claim 13
Dependent Claim 55 words
A method of assembling a connector, comprising the steps recited in claim 12, and further characterized by the step of inserting said filter assembly into a connector such that said tines engage and are deflected radially inward by a shell of said connector to establish a positive electrical connection between said plate and said shell.
Claim 14
Independent Claim 28 words
A method as claimed in claims 12 or 13, characterized in that said step of connecting comprises the step of soldering said outer electrode portions to said plate.
Claim 15
Dependent Claim 57 words
A method as claimed in claim 13, further characterized by the step of inserting feedthrough contacts into central apertures of said filter elements such that compliant sections on said contacts deflect radially inward in response to engagement with substantially cylindrical inner electrodes of said capacitors to establish an electrical connection between said inner electrodes and said contacts.
Claim 16
Dependent Claim 43 words
A method as claimed in claim 15, further characterized by the step of testing said connector before permanently fixing said plate, filter elements, and contacts in said connector, and removing said plate and filter elements or contacts if the connector fails a test.
