Card-edge connector having latches interlocked with printed circuit board

An electrical connector assembly comprising:

• a PCB having a mating portion with at least one lock portion;
• an insulative housing defining a front face, at least one longitudinal receiving slot running through the front face for receiving a printed circuit board (PCB) and at least one cavity running through a rear surface and communicating with the receiving slot;
• and
• at least one terminal retained in the respective cavity, the terminal having a base portion, a contact portion extending into the receiving slot for resiliently abutting against the PCB and a tail portion extending rearward from the base portion for electrically connecting with wires;
• wherein the insulative housing has at least one lock arm formed integral therewith, the lock arm has at least one detent for engagement with the pawl of the PCB.

An electrical connector assembly comprising:

• a printed circuit board defining a planar mating edge region with at least one conductive trace and at least an immoveable latch thereon;
• an electrical connector including an insulative housing defining at least one mating slot receiving said mating edge region therein;
• at least one conductive contact disposed in the housing with a contacting section exposed in the mating slot and mating with the conductive trace;
• and
• at least a moveable latch formed on the housing and in latchable engagement with the immoveable latch to retain said connector to the printed circuit board.
