ABSTRACT:
A device for aiding insertion of a printed circuit card into, and removal of the card from, a receptacle, the card having electrical connectors along a first edge and the receptacle having a control member located to be adjacent a second edge of the card, opposite the first edge, when the card is inserted in the receptacle, the device comprising: an insertion-extraction lever pivotally mountable on the card at a pivot axis located between first and second arms of the lever, for pivotable movement between locking and extraction positions, the first lever arm being formed to cooperate with the control member when the card is inserted in the receptacle such that movement of the lever into the locking position causes the first lever arm to engage the control member to lock the card in the inserted position, and movement of the lever toward the extraction position causes the first lever arm to cooperate with the control member to move the card in a direction for removal from the receptacle; a catch mountable on the card adjacent the second edge at a location spaced from the pivot axis of the lever; and a latch member pivotally mounted to the second lever arm to positively engage the catch when the lever is in the locking position, the latch member being pivotable relative to the lever to a release position in which the latch member disengages from the catch.
