Card connector and elastic contact piece

摘要

A card connector has a plurality of contact terminals, each of which comprises a fixed portion securely fixed in a connector housing and a spring portion having a contact portion at an end thereof opposite the fixed portion and extending from the fixed portion to be elastically displaceable. A card having a plurality of contact pads formed thereon is accommodated and held in the connector housing in such a way that the plurality of contact pads engage the associated contact portions of the plurality of contact terminals arranged in the connector housing. A cross section of the spring portion is changed along its length by changing its width or thickness so that a mass of a part of the spring portion of each contact terminal near the fixed portion is larger than a mass of a part of the spring portion near the contact portion.
