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

Abstract

The invention relates to an anti-pull-out socket and plug based on the principle of thermal expansion and cold contraction, and relates to the technical field of household appliances. The anti-pull-out socket and plug comprise a socket. Evenly distributed springs 1 are fixedly connected on the inner bottom wall of the socket. A conductive column movably connected with the inner bottom wall of thesocket is fixedly connected on the top of the springs 1. The middle part of the socket is provided with an air cavity, and a fan is fixedly connected on the bottom of the air cavity. According to theanti-pull-out socket and plug based on the principle of the thermal expansion and cold contraction, the bimetal sheet is in the straight line state in the initial state through the combination of bimetal sheet and piston rod. When the plug is plugged into the socket, the switch is pressed and the circuit is connected, the conductive strip and the conductive sheet are heated by the current and thebimetal sheet bends to one side of the limiting groove and is clamped with the limiting groove. Meanwhile, the piston rod pushes the bimetal sheet to one side of the limiting groove so that the bimetal sheet rotates and the plug is prevented from being pulled out, thus 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...
