Short circuit overheating protection plug

Abstract

The invention relates to a short circuit overheating protection plug. The plug comprises a shell and a plurality of conducting plates, wherein the shell is in a hollow structure; the conducting platesare slidably connected to a side wall of the shell; a connecting plate is adhesively fixed on the plurality of conducting plates; an upper end of the shell is provided with a chute; a control rod isslidably connected in the chute; a first spring is adhesively fixed on the control rod; and one end, away from the control rod, of the first spring is adhesively fixed on an inner wall of the shell. The short circuit overheating protection plug has the advantages that when the conducting plates emit heat due to poor contact with a metal shrapnel in a socket, a steel ball strikes the connecting plate and drives the conducting plates to vibrate and moves at a distance toward the socket direction, at this time, the conducting plates and a thermoelectric power generation strip are out of contact so that an electromagnet is deenergized; the steel ball resets under the action of a second spring; the abovementioned operations are repeated so that the conducting plates and the socket are connectedmore tightly to prevent the dangerous condition that the short circuit is caused by overheating of the plug due to poor contact.

Description

technical field [0001] The invention relates to the technical field of power plugs, in particular to a short-circuit overheating protection plug. Background technique [0002] With the improvement of living standards and the acceleration of the pace of life, more and more various household appliances appear in our families, and almost all fixtures in real life use plugs to plug into sockets to get electricity. Reliable contact of the socket. The existing connection method is that the socket contains two pieces of metal shrapnel to clamp the conductive piece of the plug. In actual use, the metal shrapnel in the socket will still have poor contact with the plug. There are many reasons Types: 1. The socket is aging, and the metal shrapnel cannot clamp the plug; 2. The plug is not inserted tightly. [0003] When the contact between the socket and the plug is not good, especially when the connection effect between the socket shrapnel and the plug conductive sheet is poor, the re...

[0002] With the improvement of living standards and the acceleration of the pace of life, more and more various household appliances appear in our families, and almost all fixtures in real life use plugs to plug into sockets to get electricity. Reliable contact of the socket. The existing connection method is that the socket contains two pieces of metal shrapnel to clamp the conductive piece of the plug. In actual use, the metal shrapnel in the socket will still have poor contact with the plug. There are many reasons Types: 1. The socket is aging, and the metal shrapnel cannot clamp the plug; 2. The plug is not inserted tightly.

[0003] When the contact between the socket and the plug is not good, especially when the connection effect between the socket shrapnel and the plug conductive sheet is poor, the resistance at the connection between the socket and the plug will increase significantly, resulting in a sharp increase in the heat generated at the connection between the two, and the heat will accumulate to a certain extent. It will burn the socket and plug and cause a short circuit, or even a dangerous situation of fire
