Patent ID: 7511524

Claim:
A contact tip structure of a connecting element comprising a fixing post coupled to a first electronic component; a beam extending away from said fixing post; a base coupled at one end of the said beam; and a contact tip extending vertically from the bottom surface of the said base, characterized in that; the beam includes an elastic region and an inelastic region extending at a shorter distance than the elastic region; the base vertically extends from the inelastic region in a certain distance; the contact tip is coupled to the bottom surface of the base to have a free end thereon; and the horizontally extended length (L) of the elastic region of the beam and the vertically extended length (D) of the base are determined in order that a horizontally movement distance of the contact tip has predetermined values, wherein the height of the contact tip is limited by the length of the free end; and the horizontal movement distance of the contact tip is determined according to the following formula: Dsin Î¸+L(cos Î¸âˆ’1) where Î¸ means an angle of elastic deformation in the elastic region.
