Three-pole power outage and leakage protection plug

Abstract

A three-pole power-off leakage protection plug, including a main frame, a sliding seat that can move up and down in the main frame, a driving rod that can move up and down and is inserted on the main frame, and is arranged on the driving rod and used to drive it to move upwards. The first drive assembly and the positioning device arranged on the main frame and used to lock or release the drive rod, the bottom surface of the main frame is provided with a first lower pressing contact piece, a first contact and a grounding contact, the first lower pressing contact piece includes The first fixed end installed on the main frame and the first lower pressing end connected with the first fixed end and located above the sliding seat, the first lower pressing end and the first contact are arranged oppositely, and the sliding seat is provided with a grounding contact piece , the grounding contact sheet is set opposite to the grounding contact. The invention has a simple structure, and when there is an electric leakage, the first pressing end is separated from the first contact, and the grounding contact piece is separated from the grounding contact, that is, all circuits corresponding to the live wire, the ground wire and the neutral wire inside the three-pole power-off leakage protection plug are realized Disconnection is equivalent to pulling out the socket, and the power-off protection is reliable to ensure the safe use of electrical appliances.

Description

technical field [0001] The invention relates to a three-pole power-off leakage protection plug. Background technique [0002] In the prior art, the internal leakage protection structure of the leakage protection plug is complex, and the power-off protection during leakage is unreliable. In addition, the existing leakage protection plug can only perform leakage detection and power-off protection for the live wire or the neutral wire, and cannot It is dangerous to detect the abnormality of the ground wire and perform power-off protection. [0003] Therefore, further improvements are required. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a three-pole power-off leakage protection plug, which has a simple structure. The separation of the contacts means that all the circuits corresponding to the live wire, ground wire and neutral wire inside the three-pole power-off leakage...
