Is the dual loop wristband easy to use?
Application range of dual loop wrist strap: each loop resistance value is 1M ohm, two loops, reliable grounding, dual loop wrist strap grounding. Anti-static wrist strap is the most basic of anti-static equipment, and it is also the most commonly used product on the production line. It is not only very convenient in installation and operation, but also the most economical in price. Its principle is through the wrist strap and grounding. The wire discharges the static electricity on the human body to the ground.
The utility model relates to an anti-static wrist strap, a dual-circuit wrist strap, in particular, a dual-circuit anti-static wrist strap that is worn on the wrist and connected to the ground to release static electricity. The utility model 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 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 , The right two blocks, the two plastic blocks are hingedly connected to each other, and the snaps on the outer sides of the two plastic blocks are respectively connected to the respective grounding wire end buckles; the hinged left plastic block of the present invention is provided with a small shaft at the right end, the small The shaft is inserted into the U-shaped groove at the left end of the right plastic block.
Compared with the prior art, the utility model reduces the probability that the insulation layer of the electronic component is broken down by static electricity even if one circuit fails without noticing the wearer of the wrist strap, and avoids a large number of products. It is scrapped or quality is reduced, the use cost is low, and the service life of the wrist strap can be prolonged.
Double loop wrist strap wrist loop: The elastic band can be adjusted. Material: elastic nylon wire and metal complex conductive white yarn woven. Wristband resistance: ≤103Ω, grounding resistance: 106Ω, static discharge time: <0.1S. Coiled wire: double-row independent wires, PU sheath, 7-core copper foil wire, 1 megohm resistance, nickel-plated iron buckle, manganese-copper flexible plug. Advantages: Two independent circuits work at the same time, which can prevent accidental short circuit or open circuit, which is safer and more reliable than a single circuit anti-static wrist.
