The discharge principle of cordless anti-static wrist strap
The cordless anti-static wrist strap has the function of eliminating static electricity without the need for a grounding wire. Compared with the corded anti-static wrist strap, the cordless anti-static wrist strap only retains the conductive bracelet on the inside, while other parts have been removed (such as wiring buttons, grounding wires, etc.), adding a main body for leakage part. At present, there are not many applications of cordless anti-static wrist straps. They are only used by relevant production managers in factories that require electrostatic protection, because it solves the problem of managers needing to move around to supervise production. The following is a brief introduction to the working principle of the cordless anti-static wrist strap.
The working principle of the cordless anti-static wrist strap: Set the main body of the wrist strap as the transmission area, inject ion exchanger into it, and add a 1MQ resistance between the transmission area and the release point. When the static electricity in the human body passes through the collection area, the inner ring conductor yarn and stainless steel sheet enter the cordless anti-static wrist strap and react with the ion exchanger placed inside it to produce a neutralizing effect, thus completing the elimination of static electricity. the goal of.
The discharge principle of the cordless anti-static wrist strap: The discharge principle actually uses the corona discharge principle to discharge electricity, which is a gas self-excited conductive phenomenon. It generally occurs in areas with very high voltages. Due to the high voltage of air-like objects in this area, the curvature radius of the charged body will be very small, which will cause the gas molecules to collide and ionize like an avalanche, thus forming self-excited conductivity. . During corona discharge, the ionization and luminescence of gas are limited to a thin layer of atmosphere near the electrode surface. This thin layer is called the "corona layer". In the space outside the electric layer, because the electric field is weak and collision ionization does not occur, corona discharge can be used to gradually leak the accumulated charge on the cordless anti-static wrist strap.
