Electric leakage protection socket with discharge metal sheets

Abstract

The invention provides an electric leakage protection socket with discharge metal sheets. The electric leakage protection socket comprises a shell, a pair of power input conductors, a pair of output conductors with conductive plug bushes and a control circuit board which is used for controlling the switching-on / switching-off of the input conductors and the output conductors, wherein the power input conductors respectively have conductive pins; a pair of discharge metal sheets are correspondingly arranged in the shell; the discharge metal sheets have contact conductive positions which are in fit with the conductive pins of the power input conductors; and the two discharge metal sheets have discharge tips or arc surfaces, which face each other at intervals. The electric leakage protection socket with the discharge metal sheets has the advantages that: the discharge metal sheets and the corresponding conductors are arranged in a separated mode; a connection mode is simple and reliable; with only a set of molds, the discharge metal sheets can be interchanged for use; the discharge metal sheets are convenient to process, and materials are saved; and the discharge metal sheets are fixedand packaged in a base of the shell, and other elements cannot be influenced in a discharge process.

Description

technical field [0001] The invention relates to a power socket, in particular to a leakage protection socket with a discharge metal sheet. Background technique [0002] Existing leakage protection sockets generally include a housing, a pair of power input conductors, a pair of output conductors with conductive sleeves, and a control circuit board for controlling the conduction / disconnection between the input conductor and the output conductor. Instantaneous high voltage (such as lightning strike) will cause damage to the leakage protection socket. The existing leakage protection socket, such as the utility model patent No. 200720178407.9, discloses a leakage protection socket with a discharge metal sheet. Each conductor extends a piece of pointed discharge metal sheet for discharge, and the tips of the two metal sheets are placed opposite each other and kept at a certain distance. The discharge metal sheet structure has the following disadvantages: Since the discharge metal...

AI Technical Summary

Problems solved by technology

The discharge metal sheet structure has the following disadvantages: Since the discharge metal sheet and the power conductor are integrally formed, it consumes a lot of materials and is inconvenient to process; the conductive socket of the metal conductor is arranged vertically and the discharge metal sheet substrate is arranged horizontally, and the precision is difficult to achieve, resulting in There may be differences in the gap between the discharge tips of each finished product, which affects the discharge effect; in addition, the metal sheet used for discharge is generally electroplated with an anti-oxidation coating, and the integrated conductor and discharge metal sheet need to be electroplated as a whole, which increases the cost, and the discharge metal sheet is due to Without sealing, it is easy to oxidize and affect the service life
