Abstract: A cycle life testing machine includes a controller, a clamping device, a driver, and a cycle device. The cycle device includes a servo motor, an actuator, a shaft, and a swing rod. The controller sends a signal to control the driver to trigger working of the servo motor, and the servo motor drives the actuator and the shaft rotate to swing the swing rod in a cycle procedure specified by the controller.

Abstract: A commutator for power supply testing includes a printed circuit board (PCB), a plurality of connectors soldered on the PCB and coupling a power supply with an electronic load, a plurality of indicator light showing whether the power supply coupled to the commutator is working, and a switch circuit. The connectors are used to couple a power supply with an electronic load. The switch circuit controls a flow of current from the power supply to the electronic load.

Abstract: A mounting apparatus includes a chassis (10), a fixing member (50) and a drive bracket (70). The chassis includes a front panel (13) defining an opening (12) and a through hole (19) therein. The fixing member includes a main body (51) mounted to the chassis. The main body includes a fixing part (63) formed upwardly therefrom, an operation part (65) extending forwardly, and an elastic hook (53) extending rearwardly therefrom. The drive bracket includes a mounting wall (73 or 71). The mounting wall comprises a stop (77) formed downwardly therefrom and an aperture (75). In assembly, the operation part of the fixing member extends through the through hole of the front panel. The drive bracket slides in the chassis from the opening thereof. The hook of the fixing member is received in the aperture of the drive bracket. The fixing part of the fixing member engages with the stop of the drive bracket.

Abstract: A computer power supply mounting apparatus includes a fixing member (40) to mount a power supply (60) into a computer chassis (20). The power supply has a front panel (62), a side panel (64) and a back panel (66). A pair of hooks (642) is formed on the side panel. The fixing member is slidably attached to the front panel of the power supply. The fixing member has a body (42) with a pair of posts (422) extending therefrom. The computer chassis includes a rear plate (22) and a side plate (24) for respectively abutting against the back panel and the side panel of the power supply. At least one rack (224) is formed on the chassis for supporting the power supply. A pair of receiving slots (242) and a pair of receiving holes (244) are defined in the side plate for respectively retaining the hooks of the power supply and the posts of the fixing member.
