Board mounted electrical connector assembly

An electrical connector assembly for mounting on a circuit board, comprising:

• a first connector including a first dielectric housing fixed to the circuit board, and a plurality of conductive terminals mounted on the housing and electrically connected to appropriate circuit traces on the board;
• a second connector mateable with the first connector in a mating direction generally perpendicular to the circuit board, the second connector including a second dielectric housing mateable with the first dielectric housing, a plurality of conductive terminals mounted on the second housing for engaging the terminals of the first connector when the connectors are mated, and at least one locking post on the second dielectric housing insertable into a locking aperture in the circuit board generally parallel to said mating direction when the connectors are mated, whereby extraneous forces applied to the second connector are passed directly to the circuit board to protect the first connector and its connections to the board;
• and
• complementary interengaging latch means between said first and second connectors when the connectors are mated.
