[0002] In today's life, electrical appliances have become an indispensable tool in life. For the convenience of use, electrical appliances and power sources are usually connected using socket strips and plugs. The socket strips in the prior art include a shell, a shell cover, and a plug-in clip between the shell and the shell cover. Although they can meet the general usage requirements, when they are not in use, the internal connecting clips will still be in a charged state. For some children, driven by curiosity, it is easy to insert foreign objects into the socket, causing electric shock accidents. At the same time, in people's lives, in some special environments, the socket strip is prone to accidental contact with water, which is also easy to cause electric shock accidents. Moreover, when the socket strip is in use, when it is over-powered and high in temperature, it is also easy to cause fire, affecting the safety of use. Therefore, the applicability and practicality are limited to a certain extent. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0030] See Figures 1 to 3As shown, a safety socket strip comprises a drain shell 1 provided with an electric plug hole 14, wherein a sealed cavity 2 is integrally formed inside the drain shell 1; a drain mounting plate 4 and a plurality of induction switches 3 are arranged inside the sealed cavity 2, and an electric contact clip 5 is installed on the drain mounting plate 4; the induction switch 3 is located above the drain mounting plate 4, and the electric contact clip 5 is electrically connected to the induction switch 3; a trigger plug 6 is plugged into the upper end of the drain shell 1, and the trigger plug 6 is plugged into the electric plug hole 14 and electrically connected to the induction switch 3 and the electric contact clip 5; an air switch 7 is fixedly installed on the outer wall of the drain shell 1, and the air switch 7 is connected between an external power source and the induction switch 3;

[0031] In this embodiment, the induction switch 3 includes a power supply module 31 fixedly installed in the sealed cavity 2, and a waterproof signal receiver 32 is electrically connected to the power supply module 31; the power supply module 31 is connected between the output end of the air switch 7 and the electrical contact clip 5, and the waterproof signal receiver 32 is fixedly installed on the outer wall of the sealed cavity 2.

[0032] The trigger plug 6 includes a plug body 61 and a signal transmitting sensor 62; the signal transmitting sensor 62 is fixedly mounted at the lower end of the plug body 61, and the signal transmitting sensor 62 cooperates with the waterproof signal receiver 32; when the trigger plug 6 is inserted into the power plug hole 14 of the drain shell 1, the waterproof signal receiver 32 receives the sensing signal of the signal transmitting sensor 62 and supplies power to the power plug hole 14. It is mainly through the signal transmitting sensor 62 on the trigger plug 6 and the waterproof signal receiver 32 in the induction switch 3 to trigger, so as to realize conduction and power off. In other structures, since there is no corresponding signal transmitting sensor 62, it will not conduct electricity after plugging. Therefore, even if there is water, there will be no electric shock caused by conduction, which is conducive to improving the safety and reliability of use.

[0033] In addition, in this embodiment, the input end of the air switch 7 is connected to a high temperature sensing switch 8 and a relay 9. By setting the high temperature sensing switch, it can timely sense whether the socket strip is in an over-power and high-temperature situation. If the safety socket strip is in an over-power and high-temperature situation, it will automatically cut off the power to prevent fire, thereby improving the safety and reliability of use.

[0034] In this embodiment, the drainage shell 1 includes a bottom shell 11 and a top shell 13; the plug-in hole 14 is set through the top shell 13, and the number of the plug-in holes 14 is the same as the number of the induction switches 3; the bottom wall of the bottom shell 11 is penetrated with a plurality of drainage holes 12. In actual application, the drainage installation plate 4 includes a mesh plate 41, and a support ring 42 integrally formed on the outer edge of the mesh plate 41; the lower end of the support ring 42 is fixedly installed with the bottom surface of the inner side wall of the bottom shell 11; the upper end of the mesh plate 41 is uniformly integrally formed with a plurality of fixed tubes 43, the electrical contact clip 5 is fixedly installed on the fixed tube 43, and the position of the fixed tube 43 matches the position of the plug-in hole 14.

[0035] In this embodiment, the number of the plug holes 14 is the same as the number of the induction switches 3, so that the effectiveness of the plugging operation can be guaranteed.

[0036] Working principle: The utility model cooperates with the sealed cavity 2, the induction switch 3, the drainage installation plate 4, the electrical contact clip 5, the trigger plug 6, and the air switch 7. When in use, the trigger plug 6 is inserted into the power plug hole 14, so that the electrical connection column of the plug body 61 is plugged and clamped together with the electrical connection clip 5. At the same time, the signal transmitting sensor 62 senses the waterproof magnetic sensor 32, so that the signal transmitting sensor 62 controls the waterproof magnetic sensor 32 to start, so that the trigger plug 6 and the electrical connection contact clip 5 corresponding to the power plug hole 14 are connected to electricity, so that it is in a charged state. At this time, the external electrical appliance installed with the trigger plug 6 can be used, and when it is not in use, when the trigger plug 6 is pulled out, the waterproof magnetic sensor 32 loses its induction, and the power supply module 31 is closed at this time, so that the electrical connection contact clip 5 is in a non-charged state, and it will not cause electric shock when it is inserted into the socket, which is beneficial to improve the safety and reliability of use.

[0037] When water enters the new type during use, the fixed tube 43 will independently pack the electrical contact clips 5 one by one, so that the water will flow from the grid plate 41 and the fixed tube 43 into the bottom shell 11 and be discharged from the drainage hole 12, so that a small amount of water will not cause a short circuit during use. When a large amount of water enters during use, if a short circuit occurs, the air switch 7 will be started to disconnect the circuit. Compared with the current socket strips, there will be no electric shock accidents, which improves the safety and reliability of use.

[0038] At the same time, it is equipped with a high-temperature sensing switch and relay, which will automatically cut off the power when the safety socket is over-powered and over-temperature, preventing fire and improving the safety and reliability of use.

[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
