An anti-pull out socket and plug based on the principle of thermal expansion and cold contraction

Abstract

An anti-extraction socket and plug based on the principle of thermal expansion and contraction, relating to the technical field of household electrical appliances, including a socket, the inner bottom wall of the socket is fixedly connected to a uniformly distributed spring one, and the top of the spring one is fixedly connected to the socket The inner bottom wall of the socket is movably connected to the conductive column, the middle part of the socket is provided with an air chamber, and the bottom of the air chamber is fixedly connected with a fan. The anti-plug socket and plug based on the principle of thermal expansion and contraction are used in conjunction with the bimetallic sheet and the piston rod. In the initial state, the bimetallic sheet is in a straight line state. When the plug is connected to the socket, press the switch to make the circuit When connected, the conductive strip and the conductive sheet are heated by the current, causing the bimetallic sheet to bend to the side of the limiting groove and engage with the limiting groove, and at the same time, the piston rod squeezes the bimetallic sheet to the side of the limiting groove, making the bimetallic sheet The metal sheet rotates to prevent the plug from being pulled out, thereby achieving the effect of preventing pulling out, ensuring the stable output of the circuit, and improving the safety of the socket.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an anti-plug socket and plug based on the principle of thermal expansion and cold contraction. Background technique [0002] Socket claims again power socket and switched socket, and socket refers to the seat that one or more circuit connections can be inserted, by which various connections can be inserted, so that it is convenient to connect with other circuits. and disconnection to achieve the final connection and disconnection of this part of the circuit. [0003] Current sockets and plugs are often accidentally pulled out during use, resulting in disconnection of power output and possible damage to electrical appliances. Therefore, plugs and sockets that ensure stable power output are urgently needed to be designed. [0004] Therefore, we propose an anti-pullout socket and plug based on the principle of thermal expansion and cold contraction to solve the above p...
