Working principle of dual-circuit anti-static bracelet


The electrostatic bracelet is composed of conductive elastic band, movable snap buckle, spring PU wire, protective resistor and plug or alligator clip. It is a small device used to release the 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 dual loop wrist straps according to their structure.


Below we will mainly introduce the dual-circuit anti-static bracelet:

Bracelet structure:

The product is equipped with a snap button on the outer side of the plastic block. The snap button passes through the plastic block through a metal connector and is connected with 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 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 unconscious Even if one circuit fails, 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 service life of the wrist strap.

Features and parameters:

1. Dual-circuit electronics;

2. Wrist ring: adjustable elastic;

3. Material: two plastic sheets (PA6);

4. Colour: Black;

5. Wrist ring resistance: ≤103Ω;

6. Coiled wire: PU sheath, 7-core copper platinum wire inside, 1MΩ resistance, two sets of grounding wires, all copper plugs;


Principle of discharge:

According to the "corona discharge" effect and the principle of tip discharge, when the accumulated charge exceeds a certain value, it is discharged into the space due to the potential difference, so as to achieve the purpose of eliminating static electricity. Features: convenient and reliable. Static electricity dissipation time <0.5s.
