Different styles of anti-static wrist straps
An anti-static wrist strap is used to discharge static electricity from the human body. It consists of anti-static elastic band, movable snap button, spring cord. Protective resistor and plug or collet. The inner layer of the elastic band is woven with an antistatic yarn, and the outer layer is woven with ordinary yarn. Main indicators Spring soft wire max large length 250cm leakage resistance 106Ω (protection resistance 106Ω). Cordless, cordless anti-static wrist strap, static ring wired wrist strap (anti-static) wireless anti-static wrist strap, anti-static wrist strap detailed wireless anti-static wrist strap, is the use of (static voltage balance) physical principles, According to the principle of "electrostatic engineering", the static electricity is transmitted by the push between the ions. The static electricity is pushed from the high-potential pushing force to push the human body electrostatic ions into the drought main body design (collection area) ), through the [charge induction principle] will make the front and back surfaces of the conductive plate with "equal anisotropy charge" - skin effect, due to the built-in ion exchanger <with its low free energy characteristics>, can be easily provided The introduced electrostatic ion isotropic charge is neutralized, so the effect of electrostatic discharge can be achieved. Another screw is provided outside the machine to connect with the internal conductor loop.
(1) It can be used as a person to improperly touch the high static power source, causing a large amount of static charge to be introduced instantaneously. When the ion is not neutralized, the ion neutralization can be provided by the external air water molecules of the screw (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 to make the potential zero function (just touch the screw to ground).
(3) It can be used as a loop detection terminal.
The wired grounding wrist strap is the basic one in the anti-static equipment. It is also a must-have item on the production line. It is not only easy to set up and operate, but also often affordable in terms of price. The reason is through the wristband. And the grounding wire, the static electricity on the human body is discharged to the earth, so the wristband must be in contact with the skin when using the grounding wire, and the grounding wire should also be directly grounded, and ensure that the grounding wire is unobstructed in order to exert a great effect.
Anti-static wrist strap electrostatic ring is a device that is worn on the wrist of the human body and vents the body to accumulate electrostatic charge. It is divided into wired type and wireless type, and has a metal ring and an elastic conductive wire mixed ring. This product belongs to the anti-static wrist strap buckle adjustment wire type, it can effectively protect the zero-resistance parts, from the interference of static electricity, to discharge the static electricity of the human body. It consists of an anti-static elastic band, a snap button, a spring cord, a protective resistor and a collet. The inner layer of the elastic band is woven with an antistatic yarn, and the outer layer is woven with ordinary yarn. The principle of the anti-static wired wrist strap is to guide the static electricity of the human body to the earth through the wrist strap and the grounding wire. When using the wrist strap to contact the skin and ensure that the ground wire is directly grounded, this can be effective. Put on this anti-static wrist strap, which can safely remove static electricity generated in the human body within 0.1 seconds. The grounding wrist strap is the basic one in anti-static equipment, and it is also commonly used.
