ABSTRACT:
A friction chuck for securing a test probe within a platform holder. The chuck, formed of elastomeric material, comprises a chuck body with an axially extending bore and a plurality of downward extending fingers disposed around the outer circumference of the projection of the chuck bore. Each finger has an interior bulge that extends into the projection of the chuck bore. The bulges define a segmented aperture of a diameter less than the diameter of the chuck base. When a test probe is inserted into the chuck bore it engages the fingers and bends them outwardly. There is sufficient friction between the fingers and the test probe so that the probe is secured by the fingers. The fingers have sufficient flexibility so the probe position may be changed by hand adjustment.
