Problems solved by technology

[0002] The ground contact of the existing earth leakage protection plug is closed mainly in the following two ways: 1. It is closed by the elastic force of the ground shrapnel itself, but the elastic coefficient of the flaky shrapnel is not good. If after a certain service life or the ground wire shrapnel Deformation, then the ground wire contact will be in poor contact, the ground wire protection wire will be disconnected, and the electric appliance will be in danger of contact; Structure If the spring force of the moving reed of the zero and live wires is not enough to overcome the spring force of the spring of the ground wire, the contact of the ground wire may not be broken

Abstract

The invention relates to a current leakage protection plug, which comprises a shell. The shell is provided with a reset button and a testing button, a circuit board is arranged in the shell, the circuit board is provided with a live wire stationary contact and a zero wire stationary contact, the live wire stationary contact and the zero wire stationary contact are electrically connected with a live wire pin and a zero wire pin on the shell through wires, the shell is provided with a ground wire pin, the ground wire pin is provided with a ground wire stationary contact, the ground wire stationary contact is provided with a ground wire stationary contact, a live wire spring plate, a zero wire spring plate and a ground wire spring plate are arranged in the shell and are connected with an output power cord, the live wire spring plate, the zero wire spring plate and the ground wire spring plate are correspondingly provided with a live wire dynamic contact, a zero wire dynamic contact and a ground wire dynamic contact which are contacted with the live wire stationary contact, the zero wire stationary contact and the ground wire stationary contact, a tripping device is also arranged in the shell, and the ground wire spring plate is provided with an elastic ejection component which can eject the live wire dynamic spring plate, the zero wire dynamic spring plate and the ground wire dynamic spring plate to be away from the stationary contacts in testing or current leakage. The invention aims to provide a current leakage protection plug with high safety and simple and reliable structure.

Description

【Technical field】 [0001] The invention relates to a plug, in particular to a leakage protection plug. 【Background technique】 [0002] The ground contact of the existing earth leakage protection plug is closed mainly in the following two ways: 1. It is closed by the elastic force of the ground shrapnel itself, but the elastic coefficient of the flaky shrapnel is not good. If after a certain service life or the ground wire shrapnel Deformation, then the ground wire contact will be in poor contact, the ground wire protection wire will be disconnected, and the electric appliance will be in danger of contact; If the structure is zero, the elastic force of the moving reed of the live wire is not enough to overcome the elastic force of the shrapnel of the ground wire, and the ground wire contact may not be broken. [0003] The present invention is made based on the above circumstances. 【Content of invention】 [0004] The invention overcomes the disadvantages of the prior art an...
