Abstract

PURPOSE:To maintain extremely low contact resistance stable for a long term and besides, enable the downsizing of the body by applying electrical connection to at least one among the contacts of a connector by means of conductive matter which does not have a shape such as liquid or the like. CONSTITUTION:The contact of a socket contact connector comprises a socket contact body 10 and mercury 11 filed up in its inside. The mercury 11 is not charged completely in the body 10, so space 12 larger than the volume of a plug contact 21 is deft, which prevents the mercury 11 from overflowing when the contact 21 is inserted in the body 10. The plug contact 21 has a packing 22 and a wiring section 23. The packing 22 is shaped to cover the whole of the packing 17 when the contact 21 is inserted in the body 10, which prevents the leakage of the mercury 11. When the connector is connected, the contact 21 is inserted from the insertion port 16 into the body 10. The contact 21 is electrically connected, being immersed in the mercury 11. Since the contact 21 makes contact with the mercury 11 all over its face, the contact resistance becomes extremely small.
