Abstract
Abstract A filter assembly for a printed circuit board connector having spring contacts with crimp barrels for connecting flexible loads. The assembly includes a ground strap having a first curved surface at one side resiliently engaging the crimp barrel of one spring contact connected to a grounded flexible lead. A second curved surface at the other side of the ground strap resiliently engages the exterior (i.e., the ground side) of a cylindrical filter. A connecting pin extending through the filter is engaged by a crimp barrel of an adjacent ungrounded spring contact. By recessing the second curved surface with respect to the first, the second curved surface will not contact the intermediate portion of the strap to receive a wall of the connector housing separating the spring contacts. The filter need not in every instance be connected to a grounded circuit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
A filter assembly for use with conventional printed circuit board connectors having separator walls forming openings for receiving conventional spring contacts having crimp barrels engaging leads, said assembly comprising: a conductive body member having integrally related resilient end members, each of said end members being curved to form with the body member a housing to snugly receive a first crimp barrel and the exterior of a filter coupled to a second crimp barrel, respectively, the free end of each of the curved members being spaced from the body member a distance less than the cross-sectional dimension of the first barrel and filter respectively, but a distance sufficient to receive a portion of their respective peripheries so as to yield, as they are forced past the respective face ends for retention within the housing, the body member having a notch therein extending substantially parallel to and between the housings and terminating at an edge and accommodating a separator wall when the spring contacts are within an opening in the printed circuit board.
Claim 2
Dependent Claim
171 words
A filter assembly for use with conventional printed circuit board connectors having separator walls forming openings for receiving conventional spring contacts having crimp barrels engaging leads, said assembly comprising: a conductive body member having integrally related resilient end members, each of said end members being curved to form with the body member a housing to snugly receive a first crimp barrel and the exterior of a filter coupled to a second crimp barrel, respectively, the free end of each of the curved members being spaced from the body member a distance less than the cross-sectional dimension of the first barrel and filter respectively, but a distance sufficient to receive a portion of their respective peripheries so as to yield, as they are forced past the respective face ends for retention within the housing, the body member having a notch therein extending substantially parallel to and between the housings and terminating at an edge and accommodating a separator wall when the spring contacts are within an opening in the printed circuit board.
Claim 3
Dependent Claim
171 words
A filter assembly for use with conventional printed circuit board connectors having separator walls forming openings for receiving conventional spring contacts having crimp barrels engaging leads, said assembly comprising: a conductive body member having integrally related resilient end members, each of said end members being curved to form with the body member a housing to snugly receive a first crimp barrel and the exterior of a filter coupled to a second crimp barrel, respectively, the free end of each of the curved members being spaced from the body member a distance less than the cross-sectional dimension of the first barrel and filter respectively, but a distance sufficient to receive a portion of their respective peripheries so as to yield, as they are forced past the respective face ends for retention within the housing, the body member having a notch therein extending substantially parallel to and between the housings and terminating at an edge and accommodating a separator wall when the spring contacts are within an opening in the printed circuit board.
Claim 4
Dependent Claim
171 words
A filter assembly for use with conventional printed circuit board connectors having separator walls forming openings for receiving conventional spring contacts having crimp barrels engaging leads, said assembly comprising: a conductive body member having integrally related resilient end members, each of said end members being curved to form with the body member a housing to snugly receive a first crimp barrel and the exterior of a filter coupled to a second crimp barrel, respectively, the free end of each of the curved members being spaced from the body member a distance less than the cross-sectional dimension of the first barrel and filter respectively, but a distance sufficient to receive a portion of their respective peripheries so as to yield, as they are forced past the respective face ends for retention within the housing, the body member having a notch therein extending substantially parallel to and between the housings and terminating at an edge and accommodating a separator wall when the spring contacts are within an opening in the printed circuit board.
Claim 5
Dependent Claim
37 words
A filter assembly according to claim 1 wherein the edge in which the notch terminates is recessed adjacent the notch so as to prevent the exterior of the filter from being short-circuited to the second crimp barrel.
