Abstract:
A contact pin module comprising:a first connecting portion having terminal portions which are aligned in a row in an identical plane, formed of an elastic conductor electrically connected to a plurality of connecting terminals, respectively, of an object to be tested and including electronic circuits thereinto; a second connecting portion having terminal portions which are aligned in a row in an identical plane, formed of an elastic conductor consecutive to said first connecting portion and electrically connected to a plurality of electrodes, respectively, of a board connected to a signal input/output section for inputting and outputting a test signal for said object to be tested; a supporting member disposed at an approximately intermediate position between said first and said second connecting portions and supporting said conductor so that a contacting force of said terminal portion of said first connecting portion to said connecting terminal and a contacting force of said terminal portion of said second connecting portion to said electrode are individually adjustable; and a holding member for holding a plurality of said first connecting portions, said second connecting portions and said supporting members in an overlaid manner in the direction orthogonal to the array of said terminal portions, wherein a spring constant of said first connecting portion and that of said second connecting portion are set such that a contacting force between said connecting terminal of said object and said terminal portion of said first connecting portion is different from a contacting force between said electrode of said board and said terminal portion of said second connecting portion.
