The anti-static wrist strap 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 straps with buckle adjustment wired type, which 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. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body within 0.1 second. The grounded wrist strap is the most basic and most commonly used anti-static equipment.
The anti-static wrist strap is equipped with a snap buckle on the outer side of the plastic block. The snap buckle passes through the plastic block through a metal connector and is connected to the conductive webbing on the inner side of the plastic block to form two independent circuit loops. The plastic block is divided into The left and right two pieces, the two plastic pieces are hingedly connected to each other, and the snap buckles on the outer side of the two plastic pieces are respectively connected with their respective grounding wire end buckles; this product is compared with the existing traditional wrist strap, when the wearer of the wrist strap is in Even if one circuit fails without noticing, the other circuit can continue to work, reducing the probability of the insulation layer of electronic components being broken down by static electricity, avoiding mass scrap or quality degradation of products, low cost of use, and extending the use of wrist straps life. Suitable for higher-end customers.
Main indicators of anti-static wrist strap:
The maximum length of the spring cord is 250cm and the leakage resistance is 106Ω (protection resistance 106Ω).
Detailed introduction of anti-static wrist strap:
The anti-static wrist strap is developed based on the physical principle of (static voltage balance), based on the principle of "electrostatic engineering" that static electricity is transferred by the push method between ions, which is pushed by static electricity from high electric potential The characteristic of the human body pushes the electrostatic ions of the human body into the (collection area) of the drought body design, through the [charge induction principle], the front and back surfaces of the conductive plate will have "equal opposite charges"-skin effect, because the area has built-in ions The exchanger< with="" its="" low="" free="" energy="" characteristic="">, it can easily provide the introduced electrostatic ions with the same amount of the opposite charge to neutralize, so the effect of electrostatic discharge can be achieved. In addition, there is a screw on the outside of the machine. Connection with internal conductor loop
(1) It can be used to introduce a large amount of electrostatic charge due to improper touching of the high static power source by the personnel. When the ion neutralization is not complete, the external air water molecules can be used to provide the ion neutralization (for the Corona discharge effect). Effectively eliminate static electricity, and achieve the ultimate goal of static discharge (static voltage balance)
(2) This screw can be used for potential return to zero function (just touch the screw to the ground),
(3) It can be used as a loop detection terminal.
Wired anti-static wrist strap is the most basic of anti-static equipment, and it is also a must-have product in the most commonly used production line. It is not only very convenient in erection and operation, but also the most affordable in price. The reason is that the use of wrist strap and The grounding wire discharges the static electricity on the human body to the ground. Therefore, the wrist strap must be in contact with the skin when using it. The grounding wire must also be directly grounded. Ensure that the grounding wire is unobstructed to achieve maximum effect.
