Description

Smart home socket and manufacturing method thereof
Technical Field
The invention relates to a household socket, in particular to a socket for smart home and a manufacturing method thereof.
Background
Along with the development of smart homes, smart sockets are also more and more important, and various different smart sockets are continuously appeared in the market.
The common socket simply connects the live wire and the zero line of the commercial power to the corresponding jacks, and objectively only plays a role of a pure connection circuit. The intelligent socket has more functions, such as timing connection of a line, timing disconnection of the line, remote connection of the line, remote disconnection of the line, measurement of power consumption of household appliances and the like. Some intelligent sockets even have the function of connecting the internet, and a user can directly use an intelligent terminal such as a mobile phone or a tablet personal computer to remotely control the sockets, so that the intelligent degree of the sockets is greatly improved, and a lot of convenience is objectively brought to people.
However, it can be seen that a single chip microcomputer or an embedded processing unit with a specific function is used in various smart sockets, i.e., the sockets themselves consume electric energy all at once. However, a household is often equipped with dozens of sockets, and the control circuit inside dozens of sockets consumes power at any moment, which is very expensive. The socket does not meet the basic national policy of energy conservation and emission reduction and a sustainable development road. In addition, almost all the control directions of the smart sockets currently on the market are radio control. Then, several tens of radio emission sources are simultaneously arranged in a family, and complicated electromagnetic waves are strengthened by multiple reflections indoors, so that the influence on the human body is very adverse, and the influence on infants and pregnant women is more serious. In addition, from the aspect of the operation mode of the radio control socket, the socket is often installed at an indoor corner or behind furniture, and in order to enhance the stability of the communication process, the transmission power of the radio wave transmitting device must be intentionally increased in the production process, otherwise, the smart socket cannot work normally. While the radio wave emission power is improved, more serious electromagnetic radiation damage is brought to the user. And even if the transmitting power of the communication module is intentionally improved in the production process, the communication module of the socket still cannot normally work under the action of a strong electromagnetic field in thunderstorm weather. In addition to the above points, since the propagation of radio waves is radiated to the surroundings, all radio waves can be sensed by specific radio wave receiving devices within a certain range, and thus all devices communicating by radio have the possibility of being illegally remotely manipulated by others, which is very dangerous for the smart home control system requiring a large area of use.

Further, an extension spring 27 which is always in an extended state is further arranged inside the double-coil magnetic latching relay 19, one end of the extension spring 27 is fixedly connected between the metal contact a20 and the magnetizable metal block 25, the other end of the extension spring 27 is fixedly connected to the support 30, and when the metal contact a20 rotates to the left, the metal contact a20 is pulled to the metal contact B21 by the tensile force generated by elastic deformation of the extension spring 27; when the metal contact a20 rotates to the right, the tension of the spring 27 due to the elastic deformation pulls the metal contact a20 toward the metal contact C22, so that the purpose of "magnetic holding" is achieved.
