Abstract
An electrical connector includes a first connector having a plurality of electric contacts and a second connector having a plurality of electric contact elements which are to be contacted with the electric contacts of the first connector when the first and second connectors are connected. A board of the second connector which supports its electric contact elements is formed with slits closely surrounding the respective electric contact elements. Preferably, the board consists of a first board formed with the slits described above and a second board formed with an opening having an area corresponding to the whole area of the first board provided with the electric contact elements. Alternatively, small tongue-shaped movable pieces supporting the electric contacts of the second connector are previously inclined at an angle &agr; toward the electric contacts of the first connector, and the electric contacts of the second connector are inclined at an angle &bgr; in opposite side of the angle &agr; in a relation &agr;>&bgr; when the first and second connectors have been completely connected. With these construction, the electrical connector becomes compact and is able to prevent any incorrect connection between the electric contacts and the electric contact elements of the first and second connectors and to ensure the required impedance characteristics even if there are differences in height between the electric contacts of the first connector.
