Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic discharge generators, in particular to a protection mechanism. Background Art

[0002] A Faraday cage is a spatial structure with a uniform static charge distribution generated by electrostatic induction. Its interior is designed as a closed space surrounded by conductive materials. The characteristic of this device is that it can effectively conduct the static charges in the surrounding environment into the interior of the Faraday cage, making the interior of the Faraday cage full of static charges. When an external voltage is applied, these static charges will move along the direction of the electric field, thus realizing the discharge of static charges. This device can be widely used in occasions where static electricity needs to be eliminated, such as printing, packaging, electronics and other industries.

[0003] When the discharge gun end of an electrostatic discharge generator releases static electricity to detect an object, there is a possibility of accidentally igniting surrounding combustibles. Therefore, it is necessary to set a protective cover outside the electrostatic discharge generator to protect it inside, which can isolate the electrostatic discharge generator to improve the safety during use. However, when the electrostatic discharge generator works, it contacts with electrical equipment or circuit boards through an electrostatic gun, and static electricity can cause faults in electrical equipment and circuit boards as well as electrical fires. Although the protective cover avoids the damage of electrical fires to the outside world, the flame will still damage the electrostatic discharge generator and electrical equipment inside the isolation housing.

[0004] Therefore, it is necessary to provide a new protection mechanism to solve the above technical problems. Content of the Utility Model
