Connecting member and electric circuit device with the connecting member

摘要

An electrical connecting member for use in an electrical connection for connecting a first electrical circuit component on a side thereof and a second electrical circuit component on another side thereof, said electrical connecting member comprising: a plurality of layers each layer having a plurality of conductive members and an insulative holder for holding said plurality of conductive members, wherein said plurality of conductive members are arranged such that each conductive member has one end exposed on one surface of said layer and another end exposed on another surface of said layer, and makes electric contact with at least one of a conductive member immediately below and a conductive member immediately above, but does not contact conductive members laterally offset thereof, and wherein said conductive members have diameters that are substantially equal to each other, between said one surface of said layer and said another surface of said layer; and said plurality of layers are stacked such that said plurality of conductive members in one layer are connected with said plurality of conductive members in another layer, and are held by said insulative holder with a different pitch shifted slightly from said plurality of conductive members in another layer. It is a further object to provide an electrical member and an electrical circuit device which employ such an electrical connecting member.
