Patent ID: 8842442

Claim:
A guide pin device, comprising: a convex connector, comprising: a guide member; and a connection portion for connecting the guide member to a first circuit board, wherein the connection portion has two first inclined surfaces formed on two opposite sides of the guide member; and a concave connector secured on a second circuit board, the concave connector further comprising: a guide sliding slot; and two second inclined surfaces formed on two opposite sides of the guide sliding slot, each of the second inclined surfaces having an inclined corner corresponding to one of the two first inclined surfaces, wherein the inclined corners of the two second inclined surfaces are obtained by a tolerance analysis computation; wherein when the guide member of the convex connector is aligned with and is inserted into the guide sliding slot of the concave connector, the two first inclined surfaces mate with the two second inclined surfaces, and a first. connection interface of the first circuit board is engaged with a second connection interface of the second circuit board.
