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.
