Printed circuit board mounted electrical connector assembly

An electrical connector assembly for releasably connecting a first connector from one side of a printed circuit board to the printed circuit board, including a second electrical connector releasably mating to said first connector with terminal means extending through appropriate terminal-receiving holes in the printed circuit board the circuit board from a side of the board opposite said one side and electrically connecting to terminal means on the second connector and said first and second connectors sandwiching the board therebetween, comprising:

• said first connector including an elongated dielectric housing of a given width, the housing having a generally rigid locating post disposed at each opposite end thereof and adapted to pass through a locating hole in the printed circuit board;
• said second connector adapted for mounting to the opposite side of the printed circuit board and including an elongated dielectric housing having a given width wider than the width of the housing of the first connector, the housing of the second connector having a longitudinally outwardly opening semi-cylindrical locating channel at each opposite end thereof for receiving a respective one of the locating posts of the first connector and establishing a non-conductive interference fit therewith, and a pair of boardlocks disposed generally on opposite lateral sides of each locating channel and adapted for insertion into appropriate boardlock holes in the printed circuit board;
• and
• terminal means mounted on the housing of the second connector and including contact portions for electrically engaging the terminal means projecting from the first connector and tail portions for extending into appropriate terminal-receiving holes in the printed circuit board laterally outside the terminal means of the first connector.
