Title: ELECTROSTATIC SHIELDING DEVICE
Abstract:
Disclosed is an electrostatic shielding device, comprising a first shielding cover and a second shielding cover. An accommodation cavity is defined by matching the first shielding cover with the second shielding cover. The accommodation cavity is provided with a circuit board. The first shielding cover is provided with a connecting member in fit connection with the second shielding cover. A first conductive layer is covered on the connecting member, and is connected with a grounding position of the circuit board. When entering the gap where the first shielding cover is connected with the second shielding cover, static electricity is attracted by the first conductive layer, to form a current thereon, and the current then flows into the grounding position of the circuit board to prevent the static electricity from entering the accommodation cavity and contacting with an important circuit on the circuit board to cause breakdown of the circuit board. The electrostatic shielding device has a good shielding effect.
