Patent ID: 7344387

Claim:
A board-to-board connector including a receptacle and a plug which is inserted into said receptacle, wherein said receptacle comprises a receptacle insulator including two opposed side walls; and at least two opposed receptacle contacts, which are connected to a first board, symmetrically arranged and supported by said two opposed side walls, respectively; wherein each of said two opposed receptacle contacts includes an inverted U-shaped portion which is shaped along an outer surface of associated one of said two opposed side walls, and a U-shape-grooved continuity portion which extends from an end of said inverted U-shaped portion inside said associated one of said two opposed side walls; and wherein said plug comprises a plug insulator including two opposed insert walls which are to be inserted between said two opposed side walls of said receptacle insulator, and at least two opposed plug contacts, which are connected to a second board, symmetrically arranged and supported by said two opposed insert walls, respectively; wherein each of said two opposed plug contacts includes a U-shaped continuity portion which is shaped along an outer surface of associated one of said two opposed insert walls to be supported thereby, and is inserted into said U-shape-grooved continuity portion to establish electrical connection therewith; and wherein said two opposed insert walls of said plug insulator are positioned so that, when said two opposed insert walls of said plug insulator are inserted between said opposed side walls of said receptacle insulator, said U-shaped continuity portions of said two opposed plug contacts deform said U-shape-grooved continuity portions of said two opposed receptacle contacts resiliently in directions to move away from said two opposed side walls of said receptacle insulator, respectively.
