Abstract
A fastener for securing a printed circuit board to a chassis includes a body portion, legs depending from the body portion, the legs being adapted for removable attachment within holes in the chassis, a hook for slidably engaging a slot on a printed circuit board inserted thereon, and a grounding element for providing an electrical connection between the printed circuit board and a shield on the chassis. The fastener described herein enables one chassis design to accommodate a variety of sizes of printed circuit boards merely by forming holes at particular points on the chassis, thereby avoiding the expense of redesigning a chassis to accommodate a new printed circuit board.
Claims15
A fastener for attaching a printed circuit board to a chassis, comprising:
- a body portion having a first surface for supporting thereon the printed circuit board and a second surface for engagement with the chassis;
- a plurality of leg members extending from said body portion for removably attaching said fastener to the chassis, wherein said plurality of leg members include a foot member which is insertable into an aperture in said chassis to engage said chassis;
- and
- a hook for slidably embracing a first surface on the printed circuit board and holding an opposing surface of the printed circuit board against said body portion.
A fastener for releasably securing a printed circuit board having an upper face and a lower face and a slot formed therein to a chassis having an upper face and a lower face and a plurality of holes formed therein, comprising:
- a frame having an upper face and a lower face;
- a printed circuit board support element on the upper face of said frame, said support element including an upwardly facing surface for supporting the lower face of the printed circuit board;
- a plurality of legs extending generally downwardly from the lower face of said frame, each leg of said plurality of legs having an upper end and a lower end, the lower end thereof being adapted for extension through and locking within a hole in the chassis;
- a printed circuit board clasp on the upper face of said frame, said clasp being adapted for extension through and slidable engagement within the slot in the printed circuit board;
- and
- a grounding clip forming an electrically conductive connection between the printed circuit board support surface on said support element and the lower face of said frame.
