Maintenance device of micro-card self-control instrument

Abstract

The invention discloses a maintenance device of a micro-card self-control instrument. The device comprises a case and a heat dissipation cover, wherein a control panel is arranged in front of the case. The front side of the control panel is provided with a nixie tube display screen, a grounding end, a positive electrode output end, a negative electrode output end and an operation panel. A constantvoltage indicating lamp, a constant current indicating lamp, a current adjusting knob, a voltage adjusting knob and a power switch are arranged on the front side of the control panel. A high-power negative pole output terminal, a high-power positive pole output terminal, a power socket and a threaded hole are arranged in the back of the case. In conclusion, the maintenance device of the micro-card self-control instrument has the following beneficial effects: due to the adoption of a clamping groove, a transparent protective cover and a threaded hole, the heat dissipation speed is increased when the maintenance device of the micro-card self-control instrument is overheated. Meanwhile, the control panel is protected, so that a heat dissipation fan can be conveniently cleaned. The inventionprovides convenience for the usage of the maintenance device of the micro-card self-control instrument, and the device is convenient to use.
