摘要： A fixing mechanism for fixing expansion cards in place includes a fixing assembly, a clamping element opposite to the fixing assembly, and a connection element. A side of the clamping element away from the fixing assembly defines a recess for receiving the expansion card. The connection element is hinged to the fixing assembly and the clamping element. When the connection element is rotated relative to the fixing assembly and the clamping element, the clamping element is moved towards or away from the fixing assembly to adjust a distance between the fixing assembly and the clamping element.

摘要： A fixing device for fixing a data storage device includes a rack, a fixing member, and a resilient member. The rack includes a bottom plate and two tabs protruding from the bottom plate. Two first pins respectively extend from the tabs to engage in two corresponding holes defined in a first sidewall of the data storage device. The fixing member is slidably mounted on the bottom plate along a direction perpendicular to the tabs. A second pin protrudes from the fixing member to detachably engage in a locking hole defined in a second sidewall of the data storage device. The resilient member is resiliently sandwiched between the rack and the fixing member, to bias the fixing member to move towards the data storage device, thereby making the second pin engage in the locking hole.

摘要： An anti-sag apparatus is mounted in a chassis for supporting an expansion card. The anti-sag apparatus includes a fixing bracket, a mounting member, and a supporting module. The mounting member defines a slide slot and a positioning hole communicating with the slide slot. The supporting module includes a supporting member, a manipulation member, and a resilient element arranged between the supporting member and the manipulation member. The manipulation member includes a pole forming a neck able to slide through the slide slot, and a locking portion sized to be stopped from entering the slide slot. When the pole is placed in the positioning hole, the supporting member supports the expansion card. When the pole is driven to slide along the slide slot, the supporting member disengages from the expansion card.

摘要： An exemplary cabinet for electronic devices includes an enclosure and an overweight alarm device disposed in the enclosure. The enclosure is for accommodating electronic devices therein. The overweight alarm device includes a weighing circuit, an A/D (Analog to Digital) converting circuit, a control circuit and a warning circuit connected in sequence. The weighing circuit includes a weighing sensor mounted at a bottom of the enclosure for sensing a weight of the cabinet. The A/D converting circuit receives the weight from the weighing sensor, converts the weight to a digital signal and outputs the digital signal to the control circuit. The control circuit compares the digital signal with a threshold value contained therein, and controls the warning circuit to generate a warning when the digital signal is greater than the threshold value.
