Abstract:
1. An electrical connector for connecting oppositely arranged first and second mating electrical means, comprising a support member made of a non-rigid resin capable of being elastically deformed, a first circuit having a plurality of electric contact elements arranged on one surface of said support member to contact electric contacts of said first mating electrical means, a second circuit having a plurality of electric contact elements arranged on the other surface of said support member to contact electric contacts of said second mating electrical means, and conductors connecting said first and second circuits, wherein said electric contact elements of the first and second circuits are formed in the most suitable manner to meet the shapes of the mating electric contacts, respectively, wherein when said first mating electrical means is a ball grid array connector and said second mating electrical means is a printed circuit board, said electric contact elements of the first circuit are each provided on their surfaces with at least one ridge having a triangular cross-section and said electric contact elements of the second circuit are hemispherical protrusions, thereby making the surfaces of the first and second circuits different in shape, wherein said at least one ridge of each of the electric contact elements of the first circuit is formed to extend in a direction substantially parallel to the direction in which the electric contact of said first mating electrical means slides on the electric contact element upon being displaced in the urged direction by the electric contact when the electric contact contacts and urges the electric contact element in said urged direction, wherein said support member is formed through its thickness with slits closely around said electric contact elements of the first circuit which contact said electric contacts of the first mating electrical means, respectively.
