Circuit board mounting system

A system for mounting a circuit board comprising:

• an enclosure having a bottom, a front wall projecting upwardly from said bottom, spaced, opposed side walls projecting upwardly from said bottom and extending rearwardly from said front wall, and a back wall projecting upwardly from said bottom and extending between said side walls, said front wall having a plurality of spaced ports, said bottom defining a mounting plate having a plurality of parallel, spaced slits,
• a plurality of standoffs each having an elongated base with a first end and a spaced second end, and a post that projects upwardly from said first end of said base, said base having an elongated standoff aperture that extends through said base between said post and said second end of said base, said base having at least one locating indentation off-center relative to said base, such that the distance from said locating indentation to said first end is different from the distance from said locating indentation to said second end, said post having a top and a hole extending downwardly from said top for receiving a board fastener for securing said circuit board to said top of said standoff,
• a standoff fastener for each said standoff, said standoff fastener being sized to extend through said standoff aperture and into one of said slits to fasten said standoff to said mounting plate, and
• an alignment plate sized and shaped to fit over said mounting plate and having an opening for each said standoff, said openings being sized and shaped to receive said base of said standoffs, said alignment plate having a projection for each said opening to match said locating indentation on said base of said standoff,
• whereby said alignment plate is placed over said mounting plate, said bases of said standoffs are placed in said openings, and said bases are fastened to said mounting plate with said standoff fasteners to align said standoffs and precisely locate said circuit board.

An enclosure for mounting a circuit board with a communication interface connector, comprising:

• a bottom,
• a front wall projecting upwardly from said bottom, and having a plurality of spaced ports,
• spaced, opposed side walls projecting upwardly from said bottom and extending rearwardly from said front wall,
• a back wall projecting upwardly from said bottom and extending between said side walls,
• a mounting plate sized to fit inside said front, side and back walls, said mounting plate having a plurality of spaced slits,
• a plurality of standoffs each having an elongated base with a first end and a spaced second end, and a post that projects upwardly from said first end of said base, said base having a standoff aperture that extends through said base between said post and said second end of said base, and
• a standoff fastener for each said standoff, said standoff fastener being sized to extend through said standoff aperture and into one of said slits to fasten said standoff to said mounting plate,
• whereby said standoffs can be mounted anywhere along said slits and rotated about said fasteners to mount said circuit board in said enclosure and align said communication interface connector with one of said ports.
