Abstract
An electrical spring probe includes a barrel having an annular opening therethrough. A plunger is partially disposed within the annular opening at one end and is capable of slidable axial displacement within the annular opening. The plunger includes a tip positioned outside of the barrel for contacting an electrical device. A terminal member is disposed within the annular opening through the barrel at an end opposite to the plunger and is fixedly attached therein. The terminal member includes a flanged end that is positioned outside of the barrel and includes at least one flange that extends radially outward from the flanged end. The flange has a shoulder that is substantially perpendicular to an axis running along the terminal member. A slot is positioned in the flanged end and extends axially along the terminal member from tip of the flanged end a distance toward the barrel. The spring probe forms a locked attachment with a probe receptacle by a snap locking abutment of the shoulder of each flange with an outside edge of an opening in a terminal portion of the receptacle.
