Abstract:
A high-density electrical connector comprising:a plurality of contacts consisting of two sets of SMT contacts and two sets of DIP contacts, each contact having a mating portion and a mounting portion; anda dielectric housing comprising a pair of insert molded first housing members and an insert molded second housing member around the pair of first housing members and forming a pair of risers joining distal ends of the pair of first housing members, respectively, to form a closed peripheral fence therewith, said peripheral fence being insert molded to said two sets of SMT contacts in two opposite outer surfaces thereof and to said two sets of DIP contacts in two opposite inner surfaces thereof and further defining a chamber between the two opposite inner surfaces and a channel around the peripheral fence such that the SMT and DIP contacts are arranged in a very high density;wherein each set of DIP contacts comprises a first group of DIP contacts and a second group of DIP contacts alternately arranged along one surface of each of said pair of first housing members in a lengthwise direction thereof, the mounting portions of the first group of DIP contacts being offset a predetermined distance from the mounting portions of the second group of DIP contacts in a direction perpendicular to the lengthwise direction of said first housing member;wherein the proximate mounting portions of the SMT contacts are distanced a first pitch from each other in the lengthwise direction of said first housing member while the proximate mounting portions of the DIP contacts are distanced a second pitch from each other in the same direction which is double the first pitch;wherein a shield mounted on a mating face of the second housing member.
