Abstract:
A contact structure for establishing electrical connection with contact targets, comprising:a contact substrate having through holes running through upper and lower surfaces thereof; and a plurality of contactors each being uniformly made of same conductive material throughout and mounted vertically on the contact substrate where each of the contactors is comprised of an intermediate portion which is substantially straight and is inserted in the through hole provided on the contact substrate in a vertical direction, a contact portion intergral to the intermediate portion and positioned at one end of the contactor to function as a contact point, and a base portion provided at another end of the contactor, and a spring portion upwardly inclined relative to the surface of the contact substrate and provided between the base portion and the intermediate portion; wherein the spring portion has a straight beam shape and exerts a resilient contact force when the contactor is pressed against the contact target, and a part of the intermediate portion is indented to reduce its width or thickness for promoting flexibility of the contactor.
