Detailed Description of the Invention

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-5 , a leakage protection switch with a display lamp, including an external spring-type RCD body 1, an upper protective housing 2 is provided on the upper surface of the external spring-type RCD body 1, and a lower protective housing 5 is provided on the lower surface of the external spring-type RCD body 1. The upper protective housing 2 is installed on the lower protective housing 5 through a fixing member 4. The upper protective housing 2 can protect the electronic components on the upper part of the external spring-type RCD body 1.

[0022] In addition, a plurality of button activity openings 21 are symmetrically and penetratingly provided on the upper surface of the housing of the upper protective housing 2. A light guide column 3 is provided on one side of the button activity openings 21 on the upper surface of the housing of the upper protective housing 2. A plurality of mounting blocks 22 are symmetrically and fixedly connected to the bottoms of the side walls on both sides of the housing of the upper protective housing 2. Mounting holes are provided in the mounting blocks 22. The light guide column 3 can reflect the light emitted by the LED display lamp 6, so that after the upper protective housing 2 is installed, the staff can still clearly see the color change of the LED display lamp 6.

[0023] Among them, the limit card plate 23 is L-shaped, and the limit card plate 23 abuts against one side edge of the mounting plate of the external spring-type RCD body 1. The limit card plate 23 can abut against the external spring-type RCD body 1, so that the external spring-type RCD body 1 cannot be separated from between the upper protective housing 2 and the lower protective housing 5.

[0024] In addition, an LED display lamp 6 is provided on the upper surface of the external spring-type RCD body 1 on one side of the button. The light guide column 3 is provided directly above the LED display lamp 6. The light guide column 3 can effectively transmit the light source of the bottom LED display lamp 6 to the upper part.

[0025] Among them, a plurality of heat dissipation openings 51 are uniformly arranged horizontally on the side walls on both sides of the housing of the lower protective housing 5. An installation groove 52 is provided on the upper surface of the lower protective housing 5. A plurality of positioning grooves 53 are symmetrically provided on both side edges on the upper surface of the lower protective housing 5. The mounting blocks 22 are installed in the positioning grooves 53. A wire arranging opening 54 is provided in the middle of the side wall of the lower protective housing 5 on the side adjacent to the heat dissipation openings 51. The wire arranging opening 54 is convenient for the discharge of connecting wires.

[0026] In addition, a mounting plate of the external spring-type RCD body 1 is horizontally installed at the installation groove 52. A bolt hole 531 is provided on the bottom groove wall at the positioning groove 53. The fixing member 4 can be screwed into the bolt hole 531, and the mounting holes on the mounting block 22 are aligned with the center of the bolt hole 531. The fixing member 4 can install and fix the upper protective housing 2 to the upper surface of the lower protective housing 5.

[0027] Moreover, a silica gel pad 541 is attached to the surface of the cable outlet 54, and the silica gel pad 541 can protect the connecting wire.

[0028] In this embodiment, when installing the protective housing outside the external spring-type RCD body 1, first place the mounting plate of the external spring-type RCD body 1 into the installation groove 52, and ensure that the button side is facing up. Then, the upper protective housing 2 can be vertically covered on the lower protective housing 5. The switch button of the external spring-type RCD body 1 is set at the button movable opening 21, and ensure that the mounting block 22 is buckled into the positioning grooves 53 on both sides. Then, the fixing member 4 is sequentially passed through the mounting holes of each mounting block 22 and screwed into the lower bolt hole 531. When tightening the fixing member 4, the upper protective housing 2 can be pressed on the upper surface of the lower protective housing 5, and the connecting wire connected to the circuit is connected to the external spring-type RCD body 1 through the cable outlet 54. When the external spring-type RCD body 1 is operating, the LED display lamp 6 will produce different colors of light according to the short circuit or overload of the external spring-type RCD body 1 in the circuit. And through the light guiding of the light guide column 3, the staff can observe the state of the LED display lamp 6 from the upper protective housing 2.

[0029] The heat dissipation port 51 facilitates the heat dissipation of the electronic components provided at the bottom of the external spring-type RCD body 1.

[0030] In the present utility model, by installing the upper protective housing 2 and the lower protective housing 5 at the upper and lower ends of the external spring-type RCD body 1 respectively, these protective housings can effectively protect the electronic components of the external spring-type RCD body 1. And through the provided light guide column 3, even after installing the upper protective housing 2, through the light guiding effect of the light guide column 3, the light of the LED display lamp 6 is timely transmitted to the upper surface of the upper protective housing 2, so as to realize that even after the external spring-type RCD body 1 is installed with the upper protective housing 2, the staff can still clearly observe the state of the LED display lamp 6.

[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
