Working principle of anti-static metal wrist strap

The anti-static metal wrist strap consists of anti-static elastic band, movable snap buckle and spring cord. It is composed of protective resistor and plug or chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn.

The main indicators of the anti-static metal wrist strap. The maximum length of the spring cord is 250cm, and the leakage resistance is 106Ω (protection resistance 106Ω). Corded and Cordless Wrist Straps (Anti-static) Electrostatic Ring Wired Wrist Straps (Anti-static) Wireless Electrostatic Wrist Straps and Anti-static Wrist Straps Detailed introduction The wireless electrostatic wrist straps are based on the physical principle of (static voltage balance) Static electricity in "Electrostatic Engineering" is developed by using the principle of pushing between ions to push the human body's electrostatic ions from high electricity to high potential. Design (collection area) , Through [the principle of charge induction], the front and back surfaces of the conductive plate will have "equivalent charges of opposite sex"-skin effect, due to the built-in ion exchanger< using="" its="" low="" free="" energy="" characteristic="">, Easily provide the introduced electrostatic ions with the same amount of opposite charges to neutralize, so the effect of electrostatic discharge can be achieved. In addition, there is a screw on the outside of the machine to connect with the internal conductor loop.

(1) It can be used as an instantaneous introduction of a large amount of electrostatic charge due to improper touch of a high static power source. When the ion neutralization cannot be completed, it can be used to provide ion neutralization by using the screw outside air water molecules (for the Corona discharge effect) , To effectively eliminate static electricity, and achieve the ultimate goal of static discharge (static voltage balance).

(2) Anti-static metal wrist strap can use this screw for potential return function (just touch the screw to the ground)

(3) It can be used as a loop detection terminal.

The anti-static metal wrist strap can effectively protect the zero resistance parts from the interference of static electricity, and is used to discharge the static electricity of the human body. It is composed of anti-static elastic band, movable snap buckle, spring cord, protective resistor and chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the earth through the wrist strap and the grounding wire. When in use, the wrist strap is in contact with the skin, and ensure that the grounding wire is directly connected to the ground, so that it can exert the maximum effect. Wear this anti-static wrist strap. The anti-static metal wrist strap can safely remove the static electricity generated in the human body within 0.1 seconds. The grounded wrist strap is the most basic and most commonly used anti-static equipment.
