Abstract

Mounting means for removably securing a circuit board in a fixed spaced relationship to a base plate. The mounting means includes one or more fasteners, each comprised of a spacer member and a latch member. The spacer member includes a disk-like portion having a first flat surface for securement against the base plate and a second flat surface on which the circuit board is supported. A post extends from the disk-like portion second flat surface through an opening in the circuit board. The latch member is mounted for movement on the post between a first position which allows it to pass through the circuit board opening and a second position in which it is locked against one surface of the circuit board forcing the opposite circuit board surface against the disk-like portion second flat surface.

Claims

1. In combination with a circuit board and base plate, mounting means securing said circuit board in spaced relationship with respect to said base plate, said mounting means comprising:

fastener means including a latch member and a spacer member;

said spacer member including a disk-like portion having a lower surface secured to said base plate, an upper surface adapted to support said circuit board and a post extending perpendicularly from said upper surface;

means supporting said latch member on said post for movement between a first position substantially parallel to said post and a second position substantially perpendicular to said post;

detent means for detenting said latch member in said second position;

first and second support members each having a lower surface secured to said base plate and an upper surface removably supporting said circuit board, each support member upper and lower surfaces being spaced by a distance greater than the distance between said spacer member upper and lower surfaces, said first and second support members being respectively spaced in opposite directions from said fastener means;

a first hole formed in said circuit board receiving said post and latch member therethrough; and

cam means carried by said latch member for bearing against the upper surface of said circuit board as said latch member is moved from said first to said second position to thus force said circuit board toward said disk-like portion upper surface.

2. The combination of claim 1 wherein said supporting means includes a pivot pin carried by said post and wherein said latch member includes an elongated slot threading said pivot pin whereby said latch member can both pivot and move linearly with respect to said pivot pin;

and wherein

said detent means comprises a recess formed contiguous with and extending substantially perpendicular to said slot for receiving said pin to restrict linear movement of said latch member.

3. The combination of claim 1 wherein said fastener means is formed of electrically insulative material.

4. The combination of claim 1 including screw means extending through said base plate and respectively threaded into said fastener means spacer member and each support member for securing them against a first surface of said base plate, said screw means configured so as to not protrude beyond a second surface of said base plate.

5. The combination of claim 1 wherein each support member upper surface comprises a tapered shoulder.
