Patent ID: 6951490

Claim:
A connector assembly comprising: a first housing having a retention arm, said retention arm including a longitudinal portion and a perpendicular portion, said perpendicular portion including a first serrated ridge; and a second housing having an opening for receiving the retention arm, said second housing including a second serrated ridge within the opening, said retention arm being moved initially to a first direction in said opening and then in a different second direction in said opening, wherein the first ridge and the second ridge move toward and then past one another, so as to be fixedly engaged to hold the retention arm in the opening, wherein the first housing and the second housing each have a lower side for connecting to a printed circuit board (PCB), wherein at least one of the lower sides includes non-electrically conductive guide pins for aligning the first housing and the second housing with the PCB; and, wherein the retention arm can move longitudinally within the opening from a point where the first serrated ridge and the second serrated ridge engage to a point where the retention arm abuts an end of the opening so as to ensure the proper alignment of the guide pins with the PCB.
