Abstract: A card support releasably retains the edges of a plurality of electronic cards in a card guide panel. The card support is formed with a card support bracket and a plurality of card retention tabs connected to the bracket by way of flexible members for releasably retaining the edges of respective cards in guide channels of the card guide panel. The retention tabs have ramps on one side for engagement with the edges of the cards being installed for momentarily moving the tabs back out of the way, allowing the cards to slide past the tabs. Once installed, the opposite sides of the tabs, which are flat, extend over the rear edge of the installed cards to retain them in the guide channels, especially during shock and vibration, including dropping the box upside down.

Abstract: A hot plug retainer and actuator is used on a chassis for releasably securing a component on the chassis. The retainer and actuator includes a one piece body having a first portion, a second portion and a living hinge pivotably connecting the first and second portions to one another for opening and closing the actuator.

Abstract: A connector for connecting first and second parts, e.g., first and second printed circuit boards, includes a post having a first end fixedly connectable to the first part and a second end having an enlarged head, and a support having a base portion fixedly connectable to the second part and an aperture through which the post can be inserted in a first direction. A lever is mounted at a portion between its ends on a pivot provided on the support, the pivot having a longitudinal axis extending in a second direction perpendicular to the first direction. The lever has an engagement surface at one end substantially aligned with the aperture for engaging the enlarged head of the post.
