ABSTRACT:
A unitary retention arm or holder for use with a printed circuit card or board. The holder comprises an elongated L-shaped arm of generally rectangular cross section, being wider at its base than at its L-shaped opposite end. The L-shaped end has a narrow channel formed therein for receiving the edge of a printed circuit card, with a guiding ramp or chamfer leading to the channel. A threaded bolt is molded into the base of the holder. The holder is formed from a slightly flexible plastic.
In operation, the holder is attached to a printed circuit card frame or cage or other support means with its base bolted near individual card connectors. A printed circuit card having edge connectors is inserted into its appropriate card connector, the card holder is flexed away from its associated printed circuit card, and then the outer edge of the printed circuit card is pressed into the channel formed in the L-shaped end of the holder. The holder may then be released and will hold the printed circuit card firmly in a perpendicular position with respect to the card edge connector. To release the holder, the operator pulls outwardly on the outer edge of the L-shaped leg of the holder, thus allowing the printed circuit card to slip out of the channel formed in the L-shaped leg.
There is also described a two-piece telescoping printed circuit card holder having releasably lockable fastening means to adjust the length of the card holder for various sizes of printed circuit cards.
