PCBA mounting assembly for tool-less attachment and release

摘要

A mounting assembly is provided for use in mounting a printed circuit board to a computer chassis. The mounting assembly includes standoffs attached to the chassis wall to extend outward into the chassis. Each standoff includes an elongated body and a neck extending from the body and having a smaller diameter than outer dimensions of the body. Each standoff includes a head extending from the neck. The mounting assembly includes retention assemblies that are mounted to the printed circuit board. Each retention assembly includes a spring-force retention member (such as a single coil of a ring spring) with an inner passageway with an at rest diameter smaller than the head. The printed circuit board is mounted to the chassis wall by pressing the printed circuit board onto the standoff elements, which are clasped by a spring force applied by each of the spring-force retention members on the standoff necks.
