Circuit Board Holder

Circuit board holders 1 provide for the mounting of circuit board 2 in a plane parallel to that of planar shield 3, without the requirement of any holes or special edge configuration at the edges of board 2.

In Figs. 1 and 2, holders 1 include bases 4 having single tabs 5 and protrusions 6 projecting from the surfaces of bases 4 that contact shield 3. Tabs 5 and protrusions 6 extend through holes 7 of shield 3. The angle of tabs 5, the length of protrusion 6, and the matching, reverse angles of teeth 8 on tabs 5 and depressions 9 at shield 3 provide secure, locking engagement of base 4 and shield 3.

Columns 12 extend from base 4 in a direction opposite to that of tabs 5. Columns 12 may have elliptical or similarly shaped cross sections to strengthen the columns in one axis, while allowing smooth air flow around the columns 12 for enhancement of the cooling of components on board 2.

At the opposite ends of columns 12 are mounted circuit board edge securing strips 13 having grooves 16, into which the edges of the circuit boards 2 slide. Ends 17 of grooves 16 are closed, while ends 18 of grooves 16 are open to allow board 2 to be slipped into grooves 16, in the forward direction indicated by arrow 19, with shrouds 20 removed from board 2.

In Figs. 1 and 3, as board 2 is moved forwardly in grooves 16, the engagement of steps 22 and ends 17 prevents further forward movement. Shrouds 20 are then placed over ends 21 of board 2 to prevent movement of...
