Abstract: An electrical connector is provided which can releasably engage a circuit card within a slot defined by the electrical connector. A camming mechanism is provided which includes a cover having a series of follower surfaces for cooperating with a corresponding series of camming surfaces and recesses associated with a pin holder. Longitudinal movement of the cover causes the cooperating surfaces to spread open card edge receiving portions of the slot, or to close down over the portions of the circuit card to be engaged. The electrical connector preferably has an opening in one end to allow a circuit card to enter the slot from the side, allowing circuit cards to be removed from or installed in a rack, frame or other chassis from the side.

Abstract: An apparatus is provided for retaining a threaded fastener in an aperture of a support. The apparatus includes a flange position to limit the insertion of the apparatus within the aperture of the support. The apparatus also includes a body extending axially from the flange and being sized for insertion within the aperture of the support. The body defines an opening extending through proximal and distal sections of the body. The opening in the body is sized to receive a threaded fastener in the proximal section of the body, and the opening in the body is sized for engagement of the threaded fastener in the distal section of the body. The proximal section of the body is configured for radial deformation upon engagement of the threaded fastener in the distal section of the body. Such deformation prevents removal of the body of the apparatus from the aperture of the support. A fastener system and a rack mount computer cabinet including the apparatus are also provided.
