Voltage detection circuit and operating method thereof

Abstract

The invention discloses a voltage detection circuit and an operating method thereof. The device used in the method is composed of a fixed socket and a power-on plug, wherein the fixed socket includesa base, the base is internally provided with an inserting slot with the opening facing upwards, the lower end wall of the inserting slot is provided with left-right symmetrical power-on jacks with theopenings facing upwards in a communicated manner, the lower end walls of the power-on jacks are fixedly provided with a power-on device, the inserting slot is provided with lifting sliding slots withthe openings being opposite to each other in a communicated manner, the lower side of each lifting sliding slot is provided with an annular slot in a communicated manner at the periphery of the inserting slot, the annular slots are respectively provided with front-back symmetrical sliding slots in a communicated manner, each sliding slot is slidably provided with a locking rod, the left side of each sliding slot is provided with a limiting slot with the opening facing towards the right in a communicated manner. The device is simple in structure and convenient to operate, the power utilizationsafety is ensured by double locking such as rotation locking and pressing locking, the locking structure is simple and easy to operate, and the use is facilitated; and secondly, the power utilizationstability is guaranteed through an overload protection circuit.

Description

technical field [0001] The invention relates to the technical field of electricity safety, in particular to a voltage detection circuit and an operation method thereof. Background technique [0002] The current electrified sockets are divided into locking and non-locking two ways to stably connect the plug to the socket. The non-locking device is widely used, but it is easy to fall off and cause unstable power consumption, and children or others are easy to touch the electrified wire when passing by and pull the plug. Make electricity interruption, and secondly, because of the complexity of operation, the inconvenience of locking and unlocking operation of the energized socket with its own locking function has not been widely used, and the cost is high. Therefore, there is an urgent need for a safe, efficient and stable voltage Detection circuit and method of operation. Contents of the invention [0003] The object of the present invention is to provide a voltage detectio...
