[Prior art]

 In conventional protection equipment for electrical equipment, a permanent (non-melting) fuse is generally attached to the main switch, and when current is overloaded, the non-fusing fuse is a protection method in which the main switch is braked down. However, since no protective device is installed between the main switch and each outlet or between each switch, the excess current capacity may be applied to the indoor wall while the switch with non-fusible fuse of the main switch is not functioning. There is a risk of damaging electrical wiring. Once the electrical wiring is burned, it will not only need to be costly and time consuming to repair, but it may also threaten life property. It is not economical and cannot guarantee safety. Therefore, the present invention has been made to improve and propose the shortcomings of conventional electric switches or outlets without protective devices.

[Embodiment of the invention]

 As shown in FIG. 1, the protection device for an electric outlet switch according to the present invention includes a seat 1, a lid 2, and a protection device 3. As shown in FIGS. 1 and 4, the main body 1 is provided with a large number of pairs of socket conductive pieces 11 and at least one pair or more of protective device conductive pieces 12, and one socket conductive piece 11 is connected via the conductive piece 13. It connects with one protective device conductive piece 12, and also connects the conductive pieces 12 of the protective device. A generally known electric plug can be inserted into the socket conductive piece 11 and the protective device conductive piece 12.

The lid 2 of the present invention is fixed on the main body 1 as a cover. The cover 2 is provided with a rectangular hole 21 corresponding to the position of the protective device conductive piece 12. Notches 211 are provided on both sides of the rectangular hole 21. Further, an insertion port 22 is provided on the cover 2 at a position corresponding to the socket conductive piece 11. As a result, after the lid 2 is placed on the sitting body 1, the socket conductive piece 11 is below the insertion port 22, and the protective device conductive piece 12 is below the rectangular hole 21. After assembling the lid body 2 and the seat body 1 integrally, they are fitted to the separately installed fixing flat plate 4 (see FIG. 2).

As shown in FIGS. 1 and 5, the structure of the protection device 3 of the present invention is as follows. A space is provided inside an outer shell 30 made of an insulating material, and an electric board 31 is provided in the space. The display lamp 34 is set on the electric board 31. A hole 302 is provided in the outer shell 30 at a position corresponding to the display lamp 34, and light from the display lamp 34 radiates from the hole 302. Two conductive springs 33 are provided below the electric board 31, and a circular tube-shaped fuse 32 can be provided in a space between the two conductive springs 33. As a result, a current flows between the two conductive springs 33. In the electric circuit of the electric board 31, the indicator lamp 34 does not light when the current flows between the two conductive springs, and the indicator lamp 34 lights when the current between the two conductive springs 33 is cut off. It is designed with such a structure. Further, a projection 301 is formed outside the outer shell 30.

As described above, the device of the present invention is designed such that when the fuse 32 of the protection device 3 is installed on the outer shell 30 and the two conductive springs 33 come into contact with the conductive portions at both ends of the fuse, the two conductive members are connected. The spring 33 forms an electric circuit and turns off the indicator light 34 according to the electric circuit design. In a normal use state, a power supply can be secured by inserting the power plug of the electric device into the conductive piece 11 of the socket through the insertion port 22. If the current is overloaded, the fuse 32 is burned and the electric circuit is cut off. At that time, the indicator light 34 is turned on according to the electric circuit design, and the light of the indicator light is emitted through the hole 302. This allows the user to determine the cause of the failure and replace the fuse by himself. Further, in the device of the present invention, when the protection device 3 is inserted into the rectangular hole 21, the protection device 3 is lower than the plane of the lid 2, so that it is impossible for a child to pull it out, so that it is safe. In the device of the present invention, the user can easily replace the fuse. The operation method is to grasp the projection 301 of the protective device 3 from the cuts 211 on both sides of the rectangular hole 21 with two fingers, then pull out the outer shell 30, remove the fuse 32, and replace it. If the fuse of the present invention burns out and there is no immediate replacement, the fuse in the car can be removed and used immediately. Buy a replacement and then replace it.

[0014] In addition to the above-described method of integrally connecting the protection device to an outlet or a switch, another embodiment of the present invention uses a separate protection device as a single unit as shown in FIG. This is an example. A pair of protective device conductive pieces 12 are provided on the seat 1 of the device, and the two protective conductive pieces 12 are connected to each other. The equipment (outlet or switch) is provided with a passage (not shown) for the passage of the line, and the line is connected to the protective device conductive strip 12 from the passage when wiring. Further, a rectangular hole 21 is provided on the lid 2 at a position corresponding to the protective device conductive piece 12, and cutouts 211 are provided on both sides of the rectangular hole 21. The structure of the protection device 3 is the same as that described above. Therefore, when the power plug of the electric product is used by being inserted into the protective device conductive piece 12, the same protective effect can be obtained.
