Abstract
Abstract A spring probe block assembly includes an insulative housing. A probe connector having a signal probe, an insulative layer, and a conductive shell is positioned within the housing. At least one ground probe is also positioned within the housing. The ground probe and the conductive shell of the probe connector are electrically connected by a grounding element. The grounding element is configured to elastically deform the ground probe in such a manner as to create spring energy in the ground probe. The spring energy generates a normal force between the ground probe and the grounding element which maintains the ground probe in its position. Also, a method for retaining a spring probe in a housing by elastically deforming the spring probe to maintain a spring force between the spring probe and the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A grounding device for electrically connecting a ground spring probe with a ground shield of a signal probe connector, the grounding device comprising: an electrically conductive grounding element in electrical contact with a ground shield of a signal probe connector, the grounding element having a non-linear bore passing therethrough; and a straight conductive ground spring probe inserted into the non-linear bore of the grounding element, the ground spring probe in electrical contact with the grounding element and elastically deformed within the non-linear bore to create a spring force between the grounding element and a ground probe sufficient to retain the ground probe within the bore.
Claim 2
Dependent Claim
105 words
A grounding device for electrically connecting a ground spring probe with a ground shield of a signal probe connector, the grounding device comprising: an electrically conductive grounding element in electrical contact with a ground shield of a signal probe connector, the grounding element having a non-linear bore passing therethrough; and a straight conductive ground spring probe inserted into the non-linear bore of the grounding element, the ground spring probe in electrical contact with the grounding element and elastically deformed within the non-linear bore to create a spring force between the grounding element and a ground probe sufficient to retain the ground probe within the bore.
Claim 3
Dependent Claim
49 words
The grounding device of claim 1 wherein the non-linear bore includes a first bore extending from a front face of the grounding element along a first axis, and a second bore extending along a second axis parallel with and offset from the first axis and intersecting the first bore.
Claim 4
Dependent Claim
42 words
The grounding device of claim 1 , wherein the non-linear bore includes a first bore extending from a front face of the grounding element along a first axis, and a second bore extending along a second axis and intersecting the first bore.
Claim 5
Dependent Claim
59 words
The grounding device of claim 1 , wherein the grounding element comprises: a front portion having a first bore extending through the front portion; a back portion having a second bore extending through the back portion; wherein the front portion and the back portion are assembled such that the first and second bores intersect and are not axially aligned.
Claim 6
Dependent Claim
66 words
The grounding device of claim 1 , further comprising a plurality of grounding elements, each of the plurality of grounding elements electrically connecting an associated ground spring probe with an associated cable shield of a signal probe connector, wherein each of the grounding elements elastically deforms its associated ground spring probe to maintain a spring force between the grounding element and the associated ground spring probe.
Claim 7
Dependent Claim
18 words
The grounding device of claim 5 , wherein each of the plurality of grounding elements is electrically commoned.
Claim 8
Dependent Claim
18 words
The grounding device of claim 5 , wherein each of the plurality of grounding elements is electrically isolated.
Claim 9
Dependent Claim
42 words
The grounding device of claim 1 , further comprising a second ground spring probe, wherein the second ground spring probe is elastically deformed by the grounding element to maintain a spring force between the grounding element and the second ground spring probe.
