Abstract:
A board-to-board electrical connector assembly for effecting a connection between two circuit boards, comprising:a first connector having a low profile generally rectangular dielectric housing including a mating face and a mounting face for mounting the connector on a first circuit board, and a plurality of spaced mating posts projecting from the mating face of the housing at four corners of the housing, each of the mating posts defined in part by two outer walls located in a respective corner of the housing; a plurality of first terminals mounted on the dielectric housing and each terminal including a tail portion for connection to an appropriate circuit trace on the first circuit board and a contact portion exposed generally at said mating face; a second connector having a low profile dielectric housing including a mating face for mating with the mating face of the housing of the first connector and a mounting face for mounting on a second circuit board, and a plurality of mating passages for receiving the outer walls of the mating posts of the first connector, the passages extending from the mating face through the mounting face of the dielectric housing of the second connector and having inner walls forming the four corners; a plurality of second terminals mounted on the dielectric housing of the second connector and each second terminal including a tail portion for connection to an appropriate circuit trace on the second circuit board and a contact portion for engaging the contact portion of one of the first terminals of the first connector; and said outer walls of the mating posts of the first connector being snugly fit against the inner walls of the mating passages of the second connector, with the outer walls of the mating posts extending all the way to the mounting face of the second connector to align the connectors, to prevent wobbling of the connectors and to maintain the contact portions of the terminals in engagement.
