Patent ID: 8039944

Claim:
An electrical connection device, comprising: a substrate having a plurality of contacting pads formed on a top surface thereof; a chip module, having an engaging surface; and a plurality of terminals formed on the engaging surface, the terminals inclining in one direction and pressed; wherein the chip module is pressed toward the substrate, and the contacting ends of the terminals contact with the plurality of contacting pads correspondingly; whereby the terminals are deformed along a deformation direction when the chip module is pressed, wherein the chip module and the contacting ends simultaneously move a horizontal displacement relative to the substrate along the deformation direction; at least one restricting structure, restricting the chip module to move along the deformation direction and restricting the horizontal displacement of the chip module relative to the substrate depending on the deformation of the terminals; wherein the restricting structure has at least two first restricting blocks which are respectively disposed on two opposite sides of the chip module for restricting the chip module to move along the deformation direction; wherein the restricting structure further has two second restricting blocks which are respectively disposed on two opposite sides of the chip module, the distance between the two second restricting blocks is larger than the length of the chip module a distance substantially equal to the horizontal movement distance of the chip module; and at least one elastic element, located on the movement path of the chip module, and continuously against the chip module during the horizontal displacement of the chip module.
