Description

Technical Field

[0001] The utility model relates to the technical field of charging pile detection, in particular to a charging pile grounding disconnection detection device. Background Art

[0002] A charging pile is a device used to charge electric vehicles, electric cars, or electric tricycles. In order to ensure the reliability of the charging pile during use, staff must regularly inspect the charging pile to check whether the grounding wire of the charging pile is broken. Currently, staff generally use a phase detector with a plug when performing grounding detection on the charging pile. When detecting the grounding condition of the charging pile, the plug of the phase detector is inserted into the socket of the charging pile, and the grounding condition of the charging pile can be determined by the display on the phase detector. Since the plugs of current phase detectors are all made of metal, they are exposed to the outside for a long time when not in use. Not only is it easy for external dust to adhere to the plug, but the plug is also prone to rust due to long-term contact with the outside world, resulting in poor contact of the plug on the phase detector and a short service life of the plug. Therefore, a phase detector with a protective function for detecting grounding disconnection of charging piles is needed. Utility Model Content

The protective mechanism is used to protect the plug 2; during use, the protective mechanism protects the plug 2, reduces the contact of external air, dust and moisture with the plug 2, slows down the rust of the plug 2, reduces the dust falling on the plug 2 from the outside, and increases the service life of the plug 2. It is easy to use and highly practical.
