Quickly remove static double loop wrist strap
The dual-circuit wristband is a device that is worn on the wrist of a human body and vents the body to accumulate electrostatic charges. It can effectively protect the zero-resistance parts from static electricity and discharge static electricity from the human body. It consists of an anti-static elastic band, a movable snap, 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. In use, the wrist strap is in contact with the skin and the ground wire is grounded directly for maximum effectiveness.
The dual-loop wrist strap is a two-loop anti-static wrist strap that is worn on the wrist to connect it to the ground to discharge static electricity.
The dual-circuit wristband wears this anti-static wrist strap, which safely removes static electricity generated in the human body within 0.1 seconds. The grounding wrist strap is the most basic and most commonly used in anti-static equipment. The double-circuit wrist strap has high safety performance and is a high-grade product. The special structural design makes it equivalent to the addition of “double insurance”, which is suitable for places or stations with extremely high static electricity requirements.
A snap button is arranged on the outer side of the plastic block, and the snap fastener passes through the metal block and is connected to the conductive webbing on the inner side of the plastic block to form two independent circuit loops, and the plastic block is divided into left and right sides. Block, 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 double-loop wrist strap is compared with the existing single-way wrist strap technology, when the wrist strap wearer is It is unaware that even if one loop fails, the other loop is still working, which reduces the probability of electrostatic breakdown of the electronic component insulation layer, avoids large-scale scrapping or quality degradation, low cost of use, and prolongs the service life of the wrist strap. .
