Abstract:
1. A contact holder adapted to contact a plurality of terminals of an electronic device to corresponding contacts of a circuit board, comprising: an insulating substrate; a plurality of conductive contacts, each inserted into and held in each of a plurality of holes formed in the substrate, wherein a conductive portion is formed on an inner surface of each of the plurality of holes, each of the plurality of conductive contacts is inserted into and held in a respective hole of the plurality of holes so that each contact is electrically insulated from the corresponding conductive portion, and each contact has plungers at the both ends thereof and a coupling member which couples the plungers, at least one of the plungers being movable in the thickness direction of the substrate; wherein the substrate has a conductive layer positioned on or above a surface of the substrate, and wherein the conductive layer is arranged so that a surface of the conductive layer is generally perpendicular to an axial direction of the contact.
