at present, plug sockets with safety doors are sold on the market, the possibility of opening one safety door by children is high, and the potential safety hazard is still small. The safety door is improved compared with the traditional product, but the original traditional structure is still kept. The second plug does not have grounding protection, and the third plug is not easy to worry people. The contact reed in the socket is easy to generate fatigue deformation, which causes poor contact with the plug sheet or small contact surface or unstable contact or no contact, the occurrence of surge with multiple peaks is high, electric arc is large and creaky, people are scared, the resistance is large, the heating temperature is increased, the electricity is wasted, and the ignition and combustion are easy. The synchronous use of two adjacent work positions of the same socket has interference. In addition, two plugs and three plugs are mixed in the same working position of the socket, the five-hole structure is small in space, and safety is a problem. The plug sheet is exposed outside for a long time, so that the use process is afraid of electric shock danger.

The internal structure characteristics, part names and implementation processes of the magnetic control floater safety plug and socket are as follows:

one, plug (upper view in figure 1, namely the front view of the half of the complete product removed)

The plug is formed by combining two half pieces, a plug piece with a certain thickness is exposed outside the traditional plug in a long length, a thin copper piece is used for covering a strong magnet to form a strong magnetic probe, and the strong magnetic probe is clamped in the two ends of the plug piece and is not exposed, and is externally connected with an electric appliance fire wire and a zero wire, as shown in figure 8. One hole in the middle is a grounding protection card and is arranged in the center of the plug piece, and as shown in fig. 9, the three holes are linearly arranged, so that the plug is much safer than the traditional two-plug without the protection grounding. The strong magnet is made of neodymium iron boron which is a new technological material and is a core piece of the plug. The plug is internally provided with an acousto-optic element 17 which can emit light and sound simultaneously after the power supply is switched on, and the plug is a humanized product design.

The electric heating device is beneficial to safety electricity utilization, and is very beneficial to caring the disabled and the old to improve the self-care ability and the life quality.

The magnetic control float safety plug and socket is designed into linear three-hole arrangement, the molded surfaces are in contact, the strong magnetic probe is close to the socket and can be automatically guided in a direction, the magnetic control float safety plug and socket are stably sucked, the plug and the pull are convenient and labor-saving, the stable one-time surface is matched, and the sparking phenomenon is less, safer and more energy-saving. The three holes are linearly arranged into a profile mode of a working position, and the method further advances the standardized production.

Second, the socket (the lower view of figure 1, the complete product is similar to the socket on the market at present and is cut out from the position of the jack)

The core technology of the socket is a floater, and the floater is mutually locked into a whole by wrapping an iron core 7.2 by a floater cap 7.1 with ear caps at two sides, which is shown in figure 7. The two floats are riveted on a floating beam 6 with certain elasticity and toughness, a supporting pressure spring 8 is positioned in the middle of the floating beam to form a seesaw structure mode, and two ends of the two floats are limited and restrained in a straight-wall channel of the inner base 4, which is shown in figure 4. The two floaters can float upwards for attraction only under the attraction of a parallel force system formed at two ends of a strong magnetic probe, and the ear caps of the floaters are in contact conduction with a hidden external power spring. The reed 3 is an elastic copper sheet and has a fine adjustment function, and is shown in figure 5.

An automatic production line can be designed for the assembled product. The analysis shows that the overall production cost is not higher than that of the traditional product.

The shape, appearance and size of the magnetic control floater safety plug and socket are completely similar or identical to those of a two-plug three-plug product in the current commodity market. The magnetic control float safety plug seeding seat can be replaced and used as long as the place for using the traditional product is provided. Because the use and installation habits, wiring modes and the like of people on traditional products are not changed, the device is more convenient and applicable, and has strong market transition performance. The extension socket is exemplified, one end of the connecting wire of the extension socket is connected with the plug of the invention, the other end of the connecting wire can be connected with the plug of the traditional product, the extension socket can still be suitable for the original wall socket or the household appliance of a family, the user does not spend much money but obtains higher guarantee in the aspects of safe electricity utilization, energy saving and environmental protection, and the extension socket is a product which parents can not know that children use more safely and is not happy. All conventional plug receptacles can be replaced again as needed or appropriate. The wall socket is replaced by the same way. The built-in household appliance socket and the electric appliance production company do not need to change the original production mode and the original product circuit structure, and the socket is suitable for being assembled in the same way.

The feasibility of the core content characteristics is realized from the small experiment and the detection of simple test products. Finally, it is noted that: the words used in this application for the composition of parts, the connection and assembly modes, the shape characteristics, the working process and principles, etc. are all broad words. For example, the term "cover-checking" and the parallel force system in the above description cannot be understood as simply consisting of two forces; float floating cannot be interpreted as only up and down displacement; the constraint of the pivot beam and the straight wall channel, the seesaw structure and the like. Further examples of linear arrangements of three holes are to be understood as meaning "hole" arrangements, which are infringed by the use of "pillars" in a linear arrangement, since the patent protection authority of "linear" arrangement is violated.
