Retention mechanism for electronic device

摘要

A retention mechanism for retaining a CPU module includes a base having two ends to which two retention arms are mounted thereby forming a U-shaped configuration for accommodating the CPU module therein. Each retention arm has a bottom wall and two side walls thereby defining a channel therebetween for receiving an edge of the CPU module. The bottom wall has a cantilevered beam extending therefrom which is deflected when the CPU module is inserted into the retention mechanism. An opening is defined in the bottom wall for partially receiving the deflected beam and the beam is dimensioned to refrain from protruding beyond the bottom wall when the CPU module is inserted into the retention mechanism.
