Contact holder

摘要

To provides a contact holder, capable of compensating a change of signal transmission characteristic at the outer edge area of the substrate. A substrate 21 has grounding conductive layers 291, 292 arranged on or above surfaces 212, 213 of the substrate, near a plunger of a signal transmitting contact 3b. Each grounding conductive layer is electrically connected to a conductive portion 241 electrically connected to each grounding contact, on surface 212 or 213 of substrate 21. Further, each grounding conductive layer is not electrically connected to the signal transmitting contact.

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.
