[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 This utility model discloses an electrical switch with leakage current detection function, comprising an electrical switch body 1 and a leakage current alarm 2 electrically connected together. When a leakage current occurs in the electrical switch body 1, the leakage current alarm 2 sounds an alarm. The electrical switch body 1 is electrically connected to an electrical plug 3 via a wire. One end of the electrical plug 3 is plugged into a power socket 4. The electrical plug 3 is plugged into the power socket 4 to supply power to the electrical switch body 1 and the leakage current alarm 2. A power cord is installed on the upper part of the power socket 4 for connecting to an external power source. A [unclear - possibly a device or component] is fixedly installed on the side wall of the electrical plug 3 away from the power socket 4. The elastic component exerts a pulling force on the plug 3 to pull it out of the power socket 4. After the two are separated, the power socket 4 no longer supplies power to the plug 3, nor to the electrical switch body 1 and the leakage alarm 2. A protective cover 5 is fixedly installed at the other end of the elastic component. Fixing blocks are provided on both sides of the protective cover 5, and each block has through holes. Bolts are threaded through several through holes. The power socket 4 has threaded holes and is threaded together with the bolts. The bolts are passed through the through holes and screwed into the threaded holes to install the protective cover 5 on the power socket 4.

[0026] A support plate is provided on one side of the power socket 4. An electric push rod 6 is clamped and fixed on one side of the support plate. A pressing plate 7 is fixed on one side of the electric push rod 6. One end of the pressing plate 7 is attached to the side wall of the plug 3 to press the plug 3 so that the plug 3 is inserted into the power socket 4. At this time, the elastic component is in a stretched state, which generates a pulling force on the plug 3. A second through groove 13 is provided on the side of the protective cover 5 near the electric push rod 6 and is through the pressing plate 7 to facilitate the pressing plate 7 to pass through the second through groove 13 and move to one side of the plug 3.

[0027] The elastic component is spring 8, and there is a gap between spring 8 and compression plate 7. Spring 8 is readily available and has a low cost.

[0028] The protective cover 5 has a first through groove 11 in the middle and a pressing rod 12 is connected through it. One end of the pressing rod 12 is fixed together with the end of the plug 3. When the operator presses the pressing rod 12 with his palm, he can push the plug 3 closer to the socket of the power socket 4, stretch the spring 8, and plug the plug 3 into the power socket 4.

[0029] The support plate has an installation slot and a controller 9 is installed thereon. The controller 9 is electrically connected to the electric push rod 6 and the leakage current alarm 2. When the electrical switch body 1 has a leakage current, the leakage current alarm 2 will start to sound an alarm and send an electrical signal to the controller 9. After receiving the electrical signal from the leakage current alarm 2, the controller 9 will supply power to the electric push rod 6. The electric push rod 6 will retract and drive the pressing plate 7 to move out of the protective cover 5. When it is disconnected from the plug 3, the spring 8 will retract and the resulting tension will separate the plug 3 from the power socket 4. The power socket 4 is equipped with a button 10 and is electrically connected to the electric push rod 6. After the staff has finished repairing the electrical switch body 1, they will press the push rod with their palm to insert the plug 3 into the power socket 4, press the button 10, start the electric push rod 6, drive the pressing plate 7 through the second through slot 13 of the protective cover 5, and move it to one side of the plug 3 and fit against the side wall of the plug 3. When the electric push rod 6 extends to its maximum length, the button 10 will be released and the electric push rod 6 will stop working.

[0030] The controller 9, leakage alarm 2, button 10, and electrical switch body 1 in this embodiment are all conventional devices known to those skilled in the art and purchased from the market. In this patent, we only use them without making any improvements to their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0031] In summary, when the electrical switch with leakage detection function is in use, if leakage occurs in the switch body 1, the leakage alarm 2, which is electrically connected to it, will sound an alarm to alert outsiders to the leakage. At the same time, it will send an electrical signal to the controller 9. After receiving the electrical signal from the leakage alarm 2, the controller 9 will supply power to the electric push rod 6. The electric push rod 6 will retract, driving the pressing plate 7 to move out of the protective cover 5. After it is disconnected from the plug 3, the spring 8 will retract, pulling the plug 3 out of the power socket 4 and disconnecting the power to the switch body 1 and the leakage alarm 2. After the maintenance is completed, the staff only needs to press the push rod with their palm to plug the plug 3 into the power socket 4, press the button 10 to start the electric push rod 6, drive the pressing plate 7 through the second through groove 13 of the protective cover 5, and move it to one side of the plug 3, where it will fit against the side wall of the plug 3. Then, the button 10 can be released.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
