Self-locking socket and plug based on capacitance change

Abstract

The invention discloses a self-locking socket and plug based on capacitance change, relates to the technical field of electric power and the self-locking socket and plug comprises a socket body, conductive columns are fixedly connected to the inner bottom walls of the two sides of the socket body, first springs are fixedly connected to the inner bottom walls of the two sides of the socket body, movable blocks movably connected with the inner wall of the socket body are fixedly connected to the tops of the first springs, and dielectric plates are fixedly connected to the middles of the movableblocks. The invention discloses a self-locking socket and plug based on capacitance change. The electromagnetic device is matched with the clamping block for use; when the plug is plugged with the socket, the plug extrudes the movable block to the bottom of the socket; the bottom of the movable block is contacted with the top of the conductive column; when the plug is pulled out by mistake, a circuit of the electromagnetic device is connected, at the moment, the clamping block moves outwards under the magnetic repulsion effect of the electromagnetic device, the clamping block is clamped with the clamping groove, movement of the plug is limited, and therefore the mistaken pulling prevention effect is achieved, the equipment plug is effectively prevented from being pulled out in the workingstate, stable work of equipment is guaranteed, and equipment burnout is effectively prevented.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a self-locking socket and plug based on capacitance variation. Background technique [0002] Electricity has brought a lot of convenience to our daily life. More and more household electrical appliances are beginning to use electricity to work, such as rice cookers, electric fans, air conditioners, and refrigerators. Connection, so as to realize the power supply, make the equipment start to work, and improve the quality of life. [0003] However, because the current plugs and sockets are directly plugged in, there is no anti-mis-unplugging device, and in daily life, because the power connection of the equipment needs wires to extend the connection distance, the wires are sometimes exposed outside, and when people walk around At the same time, because the plug is connected with the socket, it is very easy to separate the plug from the socket, causing the circuit of the wo...

Problems solved by technology

[0003] However, because the current plugs and sockets are directly plugged in, there is no anti-mis-unplugging device, and in daily life, because the power connection of the equipment needs wires to extend the connection distance, the wires are sometimes exposed outside, and when people walk around At the same time, because the plug is connected with the socket, it is very easy to separate the plug from the socket, causing the circuit of the working equipment to be disconnected and affecting the operation of the equipment. Normal operation will seriously cause the circuit of the device to burn out, causing the device to have a fault that is difficult to repair, which will seriously affect daily life, and the current plug will be inserted very tightly to prevent it from falling off, making it difficult to pull out the plug. Only by shaking the plug can the plug be pulled out. Long-term shaking will cause the plug to loosen and cause poor contact, which will affect the use of the device.
