Abstract: Disclosed is a support bar for mounting a circuit board to a housing or case. The support bar includes top and bottom, spaced apart, parallel, substantially straight legs. A base connects the legs so that the legs and the base form a U-shaped groove for receiving a portion of a side of a circuit board. A tab extends outwardly from each end of the top leg of the support bar at an acute angle from the longitudinal axis of the top leg. The tabs have a hole formed therein receiving a releasable connection pin. A hole is formed in the circuit board corresponding to the location of the hole in each of the tabs. The case include platform shoulders for supporting the support bar. The platform shoulders have holes formed therein corresponding to the location of the hole formed in the tab. Releasable connection pins are inserted through the holes in the tab of the circuit board and the housing platform to securely hold the support bar and circuit board in place with reference to the housing.
