Double loop anti-static bracelet works
The electrostatic wristband is composed of a conductive elastic band, a movable snap button, a spring PU wire, a protective resistor and a plug or an alligator clip. It is a small device for releasing static electricity stored in the human body to protect the electronic chip. The types are divided into corded wrist straps, cordless wrist straps and smart anti-static wrist straps. The corded wrist straps are divided into single-loop wrist straps and double-circuit wrist straps according to the structure.
Here we will mainly introduce the double loop anti-static bracelet:
Bracelet structure:
The product is provided with a snap on the outer side of the plastic block, and the snap is passed through the plastic block through the metal block and 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 left and right. Two pieces, two plastic blocks are hingedly connected to each other, and the snaps on the outer sides of the two plastic blocks are respectively connected with the respective grounding wire end buckles; the product is compared with the existing traditional wrist band, when the wrist band wearer is unaware Even if one loop fails, the other loop can continue to work, reducing the probability of electrostatic breakdown of the electronic component insulation layer, avoiding mass rejection or quality degradation, low cost of use, and extending the life of the wrist strap.
Features and parameters:
1. Double loop electron
2. Wrist ring: the rubber band can be adjusted;
3. Material: two plastic sheets (PA6);
4. Color: red and blue;
5. Wrist ring resistance: ≤103Ω;
6. Coiled wire: PU outer skin, inner package
7. Core copper platinum wire, 1MΩ resistor, two sets of grounding wire, full copper plug;
3 discharge principle:
According to the "corona discharge" effect and the principle of tip discharge, when the accumulated charge exceeds a certain value, the potential difference is discharged to the space, thereby achieving the purpose of eliminating static electricity. Features: convenient and reliable.
