20100099024 | METHOD FOR CONNECTION OF CONDUCTIVE MEMBER TO DEVICE - Disclosed herein are a method of coupling a conductive member for electric connection ('connection member) to a desired device by welding, wherein the connection member includes a corrosion prevention coating layer formed on a plate body of a high electrical conductivity and an embossed structure formed at one end thereof, and wherein the method comprises locating the connection member such that a protrusion of the embossed structure is brought into contact with a predetermined region of the device, at which the connection member will be connected to the device, making a welding rod come into contact with a depression opposite to the protrusion, and performing resistance welding, and a conductive connection member coupled by the coupling method. The coupling method has the effect of substituting for nickel, which has low price competitiveness, and solving the problems caused during the welding process, thereby greatly improving the productivity and greatly reducing a possibility of defect. | 04-22-2010 |
