PURPOSE:To offer an electric connecting device capable of high density connection without necessity of inserting force and extracting force, and with small connecting resistance, by using a capillary tube holding a liquid metal with capillarity and surface tension, as an electric connecting member. CONSTITUTION:An electric connecting member 1 is a minute hollow tube having the outer diameter of 0.5mm and the inner diameter of 0.3mm, and an alloy 3 of melting point 20 deg.C consisting of In (indium) 24.5wt.% and Ga (gallium) 75.5wt.% is filled into the hollow tube having an opening 2 opposite to a contact 4 of the other member. When the connecting member 1 is brought into contact with the contact 4 of the other member, the liquid alloy 3 extends the contact area with the contact 4 by the surface tension and does not disperse. Furthermore, since the liquid metals in each earth pin is communicated with each other through a hollow region extended inside a connecting board, the ground can be made equipotential. |
