Electrical collecting cover for covering an electrostatic gun and electrostatic testing device therewith

摘要

An electrical collecting cover for covering an electrostatic gun is disclosed. The electrical collecting cover includes a connecting portion for connecting with a main body of the electrostatic gun, a shielding portion connected to the connecting portion for shielding the main body of the electrostatic gun, a sleeve portion connected to the shielding portion for sheathing with a discharging head of the electrostatic gun, and an electrostatic discharge portion connected to the sleeve portion and located on a side of the discharging head for guiding static electricity from the discharging head of the electrostatic gun as the sleeve portion sheathes with the discharging head of the electrostatic gun.

主权项

1. An electrical collecting cover for covering an electrostatic gun, comprising:
a connecting portion with a side connected to a main body of the electrostatic gun; a shielding portion with a side connected to another side of the connecting portion for shielding the main body of the electrostatic gun; a sleeve portion with a side connected to the shielding portion for sheathing with a discharging head of the electrostatic gun; and an electrostatic discharge portion connected to another side of the sleeve portion and located on a side of the discharging head far from the main body for guiding static electricity from the discharging head of the electrostatic gun as the sleeve portion sheathes with the discharging head of the electrostatic gun, the electrostatic discharge portion comprising an electrostatic guiding tube and a rotary cap connected to the electrostatic guiding tube in a rotatable manner, a first opening being formed on the electrostatic guiding tube, a second opening being formed on the rotary cap, and the electrostatic discharge portion discharging the static electricity from the discharging head of the electrostatic gun when the second opening on the rotary cap is rotated to a position corresponding to the first opening on the electrostatic guiding tube.
