An interconnection device for a printed circuit board, a method of manufacturing the same, and an interconnection assembly having the same

The present invention relates to an interconnect device for a printed circuit board, a method of manufacturing the same and an inter-connect assembly having the same. According to one aspect of the present invention, the interconnect device for a printed circuit board comprises: a first contact section 10 having a bar-like shape for making contact with a second contact terminal 76 in a space transformer 52 ; a connecting section 12 having an O-ring-like shape of which one side is opened and connected to one end of the first contact section 10 in an integrated manner; a support section 14 having an engaging protrusion 14 a in a predetermined portion and connected to one end of the connecting section 12 in an integrated manner; and a second contact section 16 having an O-ring-like shape and connected to one end of the support section 14 , wherein the whole inter-connect device is made up of an identical resilient material. According to still another aspect of the present invention, an interconnect assembly having an interconnect device for a printed circuit board, comprises: a printed circuit board 40 including a contact hole 70 in which a conductive film 72 connected to an internal circuitry is formed on the inside wall; a first guide film 60 fixed on a bottom surface of the printed circuit board 40 and having a first guide opening 66 to o pen the contact hole 70 ; a space transformer having a second contact terminal 76 on a top portion and a bump 64 in the vicinity of the second contact terminal 76 ; a second guide film 62 fixed on the space transformer 52 , supported by the bump 64 , and having a second guide opening 68 to be related with the bump 64 ; and an interconnect device 2 including a second contact section having an O-ring-like shape to be inserted into the contact hole 70 by an interference fit, a support section connected to the second contact section in an integrated manner to be inserted into the inside of the first guide opening, a connecting section having an O-ring-like shape of which one side is opened and connected to the support section in an integrated manner thereby being placed between the first guide film and the second guide film, and a first contact section connected to the connecting section in an integrated manner for making contact with the second contact section 76 through the second guide opening.
