Patent ID: 8373430

Claim:
An electrical contact probe for use in a connector for connecting a first electrical device to a second electrical device, the contact probe comprising: (a) a first plunger comprising an outer portion having a contact tip adapted for making a conductive connection to an input/output terminal of the first device, and an inner portion having a lengthwise slot and two adjoining tines; each tine having an outside surface, canted surfaces, and coupling surfaces adjoining the outside surface; the inner portion of the first plunger being adapted to slidably and non-rotatably engage a second plunger; (b) the second plunger comprising an outer portion having a contact tip adapted for making a conductive connection to an input/output terminal of the second device, and an inner portion having a lengthwise slot and two adjoining tines; each tine having an outside surface, canted surfaces, and coupling surfaces adjoining the outside surface; the inner portion of the second plunger being adapted to slidably and non-rotatably engage the first plunger; (c) a coil spring having a central axis, a first end, and a second end; the first end being engaged with the inner portion of the first plunger, and the second end being engaged with the inner portion of the second plunger; wherein the plungers are slidably and non-rotatably coupled to each other, and wherein when the contact probe is compressed between the first device and the second device, the spring provides an axial bias for a conductive connection of the plungers to the respective input/output terminals of the first and the second device.
