Spring probe and method for biasing

摘要

A spring-loaded contact probe for performing tests on an electrical device. The probe includes an elongated plunger having an end with a convex surface retained within a barrel. A spring for applying an axial load is positioned within the barrel and a ball sized to translate a portion of the axial force into a side loading force is positioned between the spring and the convex surface of the plunger. The spring has a tightly wound coil adjacent the ball for maintaining the ball against the barrel.
