Patent ID: 7866986

Claim:
A conductive contact unit, comprising: a plurality of plate-like conductive contacts for electrically connecting different circuitries, each conductive contact including a first contacting element to be brought in physical contact with one circuitry, a second contacting element to be brought in physical contact with another circuitry, an elastic element that is between the first contacting element and the second contacting element and is extensible in a longitudinal direction thereof, a first connecting element that connects the elastic element and the first contacting element, and a second connecting element that connects the elastic element and the second contacting element and that has an opening penetrating therethrough in a thickness direction; a conductive contact holder including a plurality of first guiding grooves and a plurality of second guiding grooves facing the first guiding grooves, the conductive contact holder holding the conductive contacts with both longitudinal outside ends of each conductive contact being slidably engaged with the first guiding groove and the second guiding groove, the second connecting element of the conductive contact projecting from a bottom end of the second guiding groove toward outside of the conductive contact holder; and a bar-shaped member that penetrates through the openings of the respective second connecting elements of the conductive contacts, and is fixed onto the conductive contact holder, wherein the conductive contacts are slidably engaged with the first guiding grooves and the second guiding grooves such that the second contacting element rotates when a tip of the second contacting element is brought into contact with a surface of a test object and a load acts on the second contacting element.
