What is the function of the anti-static wrist strap
Anti-static wrist straps are used to discharge static electricity from the human body. It consists of an anti-static elastic band, a movable snap button, a spring cord, a protective resistor and a plug or a collet. The inner layer of the elastic band is knitted with anti-static yarn, and the outer layer is knitted with ordinary yarn. Main indicators The maximum length of the spring cord is 250cm, and the leakage resistance is 106Ω (the protection resistance is 106Ω). Cordless, cordless anti-static wrist straps, electrostatic loops Wired wrist straps (anti-static) Wireless anti-static wrist straps, anti-static wrist straps Detailed introduction Wireless anti-static wrist straps use the physical principle of (static voltage balance), According to "electrostatic engineering", static electricity is developed by using the principle of pushing and transferring between ions. The electrostatic ions of the human body are pushed against the body of drought disaster by the characteristics of electrostatic pushing from high electricity to high potential (collection area). ), through [the principle of charge induction], the front and back surfaces of the conductive plate will be respectively provided with "isotropic charges"-skin effect, due to the built-in ion exchanger <using its low free energy characteristics>, it can easily provide The introduced electrostatic ions are neutralized with anisotropic charges, so the effect of electrostatic discharge can be achieved. In addition, there is a screw outside the machine to connect with the internal conductor loop.
(1) It can be used as a source of high static electricity due to improper contact by personnel, resulting in an instant introduction of a large amount of static charge. When the ion neutralization is not completed, it can be used to provide ion neutralization by the external air water molecules of the same screw (this is for the Corona discharge effect) , to effectively eliminate static electricity, and achieve the ultimate goal of electrostatic discharge (static voltage balance).
(2) This screw can be used for potential zeroing function (just touch the screw to ground)
(3) It can be used as a loop detection terminal.
Wired grounding wrist strap is the most basic anti-static equipment, and it is also a must-have item on the most commonly used production line. And the grounding wire will discharge the static electricity from the human body to the ground. Therefore, the wristband must be in contact with the skin when using it. The grounding wire must also be directly grounded, and the grounding wire must be unobstructed to play a greater role.
The anti-static wrist strap electrostatic ring is a device that is worn on the human wrist to discharge the accumulated electrostatic charge of the human body. It is divided into wired type and wireless type, with metal ring and elastic conductive wire mixed ring. This product belongs to one of the anti-static wrist strap buckle adjustment wired type, which can effectively protect the zero resistance parts from being disturbed by static electricity, and is used to discharge the static electricity of the human body. It consists of an anti-static elastic band, a movable snap button, a spring cord, a protective resistor and a collet. The inner layer of the elastic band is knitted with anti-static yarn, and the outer layer is knitted with ordinary yarn. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the ground through the wrist strap and the grounding wire. When using, the wrist strap should be in contact with the skin, and make sure that the grounding wire is directly grounded, so as to play a greater role. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body within 0.1 seconds. The grounding wrist strap is the most basic and most commonly used anti-static equipment.
