Anti-static dual-circuit wrist strap service life and parameters
2019-11-28

The anti-static dual-circuit wrist straps are all equipped with elastic bands, movable buttons, spring cords, protective resistors, and plugs or chucks. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is usually made of yarn. It is an important part of the anti-static system to eliminate the human body, which can eliminate or control the generation of static electricity in the human body. So as to reduce the static electricity generated in the manufacturing process.

防静电双回路手腕带使用寿命和参数

The life of the anti-static dual-circuit wrist strap is closely related to the quality, and non-artificial normal work wear is the root cause of product damage. The continuous bending of the wire of the wrist strap during work will eventually break the metal fiber in the wire, causing the anti-static function of the wrist strap to fail.

At present, the better quality anti-static dual-circuit wrist straps are mainly foreign and domestic major brands, and the service life is 1-2 years. And some cheap wristbands in China are qualified as long as the product can reach the resistance of 1MΩ.

The anti-static dual-loop 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. It is divided into two pieces on the left and right. 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 wrist strap is worn Even if one circuit fails without noticing, the other circuit can continue to work, reducing the probability that the insulation layer of electronic components is broken down by static electricity, avoiding mass scrap or quality degradation of products, low cost of use, and extending the cost of the wrist strap. Service life. Suitable for higher-end customers.

Product features and parameters of dual loop wrist strap:

1. Dual-circuit electronics;

2. Wrist ring: adjustable elastic band;

3. Material: two plastic sheets (PA6);

4. Color: red and blue;

5. Wrist ring resistance: ≤103Ω;

6. Reel: PU outer skin, inner bag

7. Core copper platinum wire, 1MΩ resistance, equipped with two sets of grounding wires, all copper plugs;

1. Connect the dual-loop PU belt with one end of the automatic detection alarm device, pull the pull switch to the "ON" position, and it can be used;

2. When using, connect the alligator clips at both ends to the grounding system to form a conductive loop system;

3. In normal and good working conditions, neither the red indicator nor the green indicator light is on, and no alarm sound is emitted. When the human body is in poor contact with the tester, the red light is on and an alarm sound is emitted; when the human body is in contact with the earth When it is bad, the green light will be on and an alarm sound will be emitted; when the human body, the wrist strap and the earth have poor conductive contact, the red light and the green light will sound at the same time as the alarm sound;
