Abstract
A quarter-turn latch for fastening a first panel to a second panel includes a bolt with a bayonet key that rotationally engages a keyhole in the second panel, and a capture key that engages with the first panel to prevent loss of the bolt. A track on the underside of the second panel, surrounding a portion of the keyhole, secures the bolt in the closed position. Bump stops engageable with the bayonet key define open and closed positions. A spring integrated with the bolt prevents rattles, overcomes misalignment and/or assists disengagement of the latch. The system may be used, for example, in network interface devices (NIDs), plastic enclosures, and other devices.
