Abstract: A connector of which the terminals are staggering arranged so that each terminal is closely surrounded by another six terminals to enable an increased density of terminals in one unit area. Each of the terminals of the connector includes an upper and a lower elastic portion for respectively connecting to contacts of a working element and a printed circuit board assembled to the connector. Two forward pressures in opposite directions are applied by the working element and the printed circuit board on the connector to cause the upper and the lower elastic portions of the terminals to electrically connect to the contacts on the working element and the printed circuit board. No tin soldering is required in the assembling of the working element and the printed circuit board to the connector. And, the elastic portions of the terminal may be differently shaped.
