ABSTRACT:
A self-locking housing for an electronic circuit such as a power supply. The self-locking housing includes a printed circuit board carrying an electronic circuit, a bottom housing half, and a top housing half. The bottom housing half has locator tabs placed at one end for holding one end of the printed circuit board in a predetermined position within the interior of the bottom housing. Opposing support tabs are placed at the other end and side support tabs are provided on the side of the bottom housing. The support tabs support the printed circuit board in the bottom housing. Bottom snaps are provided on opposing sides of the bottom housing, and the printed circuit board abuts against the bottom snaps. The top housing has corresponding opposing grooves so that when the top housing is placed over the bottom housing the snaps in the bottom housing snap into the grooves so as to self-lock with the top housing. The locking of the top housing to the bottom housing entraps the PC board, and the sides of the entrapped PC board further prevent the bottom snaps from unlocking from the grooves.
