Abstract:
1. A computer housing comprising: a frame confining a mounting space; a laterally extending fixed plate mounted on said frame within said mounting space and formed with a plurality of elongated engaging slots that extend in a lateral direction; a board-mounting plate mounted detachably and slidably on said fixed plate and adapted to receive a printed circuit board thereon, said board-mounting plate being formed with a plurality of stamped tabs that extend respectively through said engaging slots, said board-mounting plate being slidable relative to said fixed plate in said lateral direction between a locking position, in which each of said tabs abuts against and engages frictionally a portion of a periphery of the respective one of said engaging slots, thereby preventing removal of said board-mounting plate from said fixed plate, and an unlocking position, in which each of said tabs disengages from said portion of said periphery of the respective one of said engaging slots, thereby permitting removal of said board-mounting plate from said fixed plate; wherein each of said engaging slots has an enlarged section and a reduced section extending and reducing from said enlarged section, said board-mounting plate being formed with a plurality of stamped holes, each of which is confined by an inner wall, each of said tabs being substantially L-shaped and including a connecting portion that extends from said inner wall of a respective one of said stamped holes through the respective one of said engaging slots in a transverse direction relative to said fixed plate, and a laterally extending portion that extends laterally from and that is transverse to said connecting portion, said connecting portion extending through said enlarged section of the respective one of said engaging slots in said transverse direction and said laterally extending portion being aligned with said enlarged section of the respective one of said engaging slots in said transverse direction when said board-mounting plate is positioned at said unlocking position, said connecting portion extending through said reduced section of the respective one of said engaging slots in said transverse direction and said laterally extending portion being aligned with said portion of said periphery of the respective one of said engaging slots in said transverse direction and engaging frictionally said portion of said periphery of the respective one of said engaging slots when said board-mounting plate is positioned at said locking position, said laterally extending portion having a leading end angled away therefrom and disposed adjacent to said portion of said periphery of the respective one of said engaging slots for guiding sliding movement of said board-mounting plate from said unlocking position to said locking position; wherein said laterally extending portion of each of said tabs has an opposite end opposite to said leading end and disposed adjacent to one side of said inner wall of a respective one of said stamped holes, said opposite end cooperating with said side of said inner wall of the respective one of said stamped holes to define a gap therebetween for receiving fittingly said portion of said periphery of the respective one of said engaging slots when said board-mounting plate is positioned at said locking position; wherein said board-mounting plate has an abutting side, said computer housing further comprising a limiting member that includes a curved spring plate and an urging member, said spring plate having a fixed end which is fixed to said frame, and a free end which is opposite to said fixed end and which abuts against said urging member in said transverse direction, said free end being disposed adjacent to and being aligned with said abutting side of said board-mounting plate in said lateral direction when said board-mounting plate is positioned at said locking position so as to limit sliding movement of said board-mounting plate in said lateral direction, said free end being resiliently depressible against said urging member to move away from said abutting side of said board-mounting elate in said transverse direction so as to permit sliding movement of said board-mounting plate in said lateral direction.
