摘要: A captive fastener attachable to a panel along a fastener axis is provided. The captive fastener includes a fastener having a head portion and a shaft extending from the head portion and along the fastener axis. The captive fastener also includes a knob having a proximal end portion engaged to the head portion of the fastener and an annular portion extending radially around the fastener axis and the shaft of the fastener. A ferrule is associated with the knob, the ferrule defining an opening extending along the fastener axis and receiving the shaft of the fastener. The ferrule has a proximal end portion configured to prevent separation of the knob from the ferrule along the fastener axis and a distal end portion configured for engagement to the panel. A spring is positioned to bias the knob or the fastener proximally relative to the ferrule and to inhibit tilting of the knob or the fastener relative to the fastener axis. The proximal end portion of the ferrule having been positioned to be associated with the knob in an insertion direction along the fastener axis, and the head portion of the fastener having been inserted within the knob for engagement to the knob in the insertion direction. The engagement between the proximal portion of the knob and the head portion of the fastener is configured to resist axial movement of the knob relative to the fastener along the fastener axis, rotational movement of the knob relative to the fastener about the fastener axis, and pivotal movement of the knob relative to the fastener axis.

摘要: A rack attachment device configured for attaching an electronic device to a rack. The rack attachment device includes a housing for coupling to the electronic device, a pawl mounted for movement relative to the housing, a slide mounted for movement relative to the housing, where the slide is positionable to contact the pawl, and a handle extending from the housing and coupled to the slide. In an unlocked position, the handle is in a first handle position and the slide is in a first slide position, such that the slide prevents the pawl from moving toward a rack aperture defined in the rack. In a locked position, the handle is in a second handle position and the slide is in a second slide position, such that the slide permits the pawl to enter the rack aperture when the slide is in the second slide position.
