The invention discloses a computer case static electricity eliminator which comprises a first resistor, a second resistor, a third resistor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a first diode, a second diode, a third diode, a switch, a slide rheostat, a bidirectional silicon controlled rectifier, a transformer and a discharge electrode. Compared with the prior art, the static electricity eliminator is formed through a simple circuit structure, static electricity of the computer case is eliminated through an active discharging design, and therefore the static electricity of the computer case is prevented from damaging a circuit board installed on the computer case, stable operation of a computer circuit is guaranteed, use is convenient and fast, and the static electricity eliminator has an application and popularization value.
Description
technical field [0001] The invention relates to a computer auxiliary circuit, in particular to a computer case static eliminator. Background technique [0002] As a part of computer accessories, the chassis plays a main role in placing and fixing various computer accessories, playing a role of support and protection. In addition, the computer chassis has an important role in shielding electromagnetic radiation. Because the chassis is not like CPU, graphics card , motherboard and other accessories can quickly improve the performance of the whole machine, so it has not been listed as a key consideration in DIY. However, the chassis will generate static electricity due to packaging, transportation, friction and other factors, and the static electricity will cause breakdown and damage to the circuit board of the computer, affecting the normal operation of the computer circuit. Therefore, there is room for improvement. Contents of the invention [0003] The object of the prese...
