Circuit board inserter/extractor

摘要

Insertion and extraction of a circuit board (40) into and from a car guide (10) is aided by a lever-like, rigid, elongated member (66) hingedly attached at one hinged end (62) thereof to one side (22) of the card guide (10). The other nonhinged end (64) of the member (66) is manipulatable so that the member (66) may be moved between an open and a closed position. A bump (70) on the member (66) contacts the trailing edge (44) of the circuit board during insertion as the member (66) is moved to its closed position. In the closed position, the member (66) extends from one hinge side (22) of the card guide (10) to the other nonhinge side (12) thereof. A locking device (94) on the nonhinge side (12) of the card guide (10) releasably engages the nonhinge end (64) of the member (66) in the closed position. For extracting the circuit board (40 ) from the card guide (10), the member (66) is moved towards its open position and a barbed portion (80) of the member (66) engages a hole (50) in a trailing edge region of the circuit board (40). The topography of the barbed portion (80), notably that of a region (100) of increased thickness disposed thereon and forming a step (106), is such that it ultimately releases itself from the hole (50).
