For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "coupling" can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this document can be understood according to specific circumstances.

[0025] In the illustrated embodiment, a socket is taken as an example, but it should be understood that any other leakage protection device applicable to the concept of the present invention is not excluded.

[0026] Combination Figures 1 to 4, shows a leakage protection device according to an embodiment of the present invention. The leakage protection device is a socket, including a shell and a core assembly arranged in the shell. Specifically, the shell includes an upper cover 1 and a base 2 connected by, for example, a snap-fit ​​structure, and the upper cover 1 is provided with socket output holes 15A, 15B, and a reset button hole 12 and a test button hole 11 for the reset button 7 and the test button 8 to protrude. Figure 4 As shown, a middle bracket 3 and a grounding frame 9 are provided in the housing, and a core assembly 21 is provided between the middle bracket 3 and the base 2. The middle bracket 3 is provided in the base 2 and covers the core assembly 21. The middle bracket 3 is used to set a live wire socket piece 4, a zero (neutral) wire socket piece 5, a grounding frame 9 and a test piece 32 thereon, and a corresponding limiting structure is provided on the middle bracket 3 to ensure that the position of each component is fixed.

[0027] In some embodiments, the leakage protection device may include a power indication function. Figure 3 As shown, the light guide column 31 is arranged on the middle bracket 3, so as to guide the light emitted by the light-emitting component on the movement assembly to the surface of the upper cover 1. Accordingly, the upper cover 1 is provided with a power indicator hole 14 for the light guide column 31 to protrude.

[0028] According to the present invention, a lighting assembly is provided in the leakage protection device, which helps to automatically light up the lighting according to the sensing of the surrounding environment conditions in an environment with poor lighting, so as to facilitate the use of the socket. Advantageously, the lighting assembly of the present invention is integrated into the operating member outside the housing, so as not to increase the overall size of the product.

[0029] exist Figure 2 In the illustrated embodiment, the lighting assembly is arranged on the middle bracket 3 and is electrically connected to the output assembly (ie, the socket sheet). It should be understood that in some embodiments, the lighting assembly may also be electrically connected to the input assembly.

[0030] Specifically, the lighting assembly includes a lighting control board 6 arranged on the middle bracket 3, and the lighting control board is electrically connected to the live wire socket piece 4 and the neutral wire socket piece 5 respectively. Figures 2 to 4 as well as Figure 6 The middle bracket 3 is provided with a live socket piece assembly slot 3A and a neutral socket piece assembly slot 3B to respectively position and assemble the live socket piece 4 and the neutral socket piece 5, and a test piece receiving slot 3D is provided to accommodate the test piece 32 of the test assembly. At the same time, the middle bracket 3 is also provided with a lighting control board assembly slot 3C to position and assemble the lighting control board 6. In the illustrated embodiment, the lighting control board 6 is arranged adjacent to the neutral socket piece 5. Accordingly, an isolation structure is provided on the middle bracket 3 to separate the lighting control board 6 from the neutral socket piece 5 to prevent undesired interference. The isolation structure can be Figure 6The isolation plate 3E or other suitable structures shown in the figure, such as isolation grooves. It should be understood that in some embodiments, the lighting control board 6 can be arranged adjacent to the live wire socket blade 4.

[0031] In order to realize the electrical connection between the lighting control board 6 and the live wire socket piece 4 and the neutral wire socket piece 5, and considering the structural layout and size factors, in some embodiments, the lighting control board 6 is provided with a power connection hole 62 ( Figure 3 ) and connected to the connection hole 41 provided on the live wire socket piece 4 through the power connection line 62A. The electrical connection between the lighting control board 6 and the neutral wire socket piece 5 can be achieved by contact. For example, the lighting control board 6 is provided with a power contact plate 63, and the power contact plate 63 contacts the power contact plate 51 provided on the neutral wire socket piece 5 to achieve electrical connection. In some embodiments, the isolation plate 3E may be provided with a conductive port 3F for the power contact plate 63 of the lighting control board 6 to reliably contact the power contact plate 51 of the neutral wire socket piece 5. Through the above layout and setting, the lighting control board 6 can be powered by the core assembly of the leakage protection device without the need for additional power supply.

[0032] Combination Figures 3 to 6 As shown, the lighting assembly also includes a sensing unit, a light-emitting unit and a light-guiding unit. The sensing unit is coupled to the lighting control board 6 and is capable of sensing the external environment of the shell. In the illustrated embodiment, the sensing unit includes a sensing element 61 coupled to the lighting control board 6, and the sensing element 61 is suitable for generating sensing information by being triggered by at least one of light, sound, wireless signal and infrared signal. The sensing unit also includes a sensing column 61A corresponding to the sensing element 61 and extending to the surface of the shell. In the illustrated embodiment, the sensing column 61A can be constructed in the form of a cover that covers the sensing element 61 and has a convex column extending to the surface of the shell. Accordingly, the shell is provided with a sensing hole 13 ( Figure 1 ).

[0033] The light emitting unit 66 may be a light emitting diode (LED) or an organic light emitting diode (OLED) or other lighting elements, and is coupled to the lighting control board 6. The lighting control board 6 can control the light emitting unit 66 to turn on or off in response to the sensing information of the sensing unit, so as to implement lighting under appropriate conditions.

[0034] In some embodiments, the sensing element is a motion sensor (such as an infrared transmitter or a camera) and generates sensing information according to the distance of the human body approaching. The lighting control panel determines whether a human body enters a preset sensing range and controls the working state of the light-emitting unit.

[0035] In some embodiments, the sensing element is a light sensor (e.g., a photoresistor) and generates sensing information according to the ambient brightness. The lighting control board determines whether the light brightness is lower than or higher than a preset brightness threshold and controls the working state of the light-emitting unit. For example, when the light is lower than the preset brightness threshold, the lighting control board controls the light-emitting unit to automatically turn on. Optionally, the lighting control board controls the light-emitting unit to turn on and maintain it for a certain period of time. When the light is higher than the preset brightness threshold, the lighting control board controls the light-emitting unit to automatically turn off. In this way, the lighting will not be turned on when the ambient light is sufficient, avoiding energy waste.

[0036] In some embodiments, the sensing element is a remote communicator, which can receive a remote control signal from a remote terminal through a communication method such as Bluetooth, Wi-Fi, etc. and generate sensing information, and the lighting control board controls the working state of the light-emitting unit based on the sensing information. The remote terminal is, for example, a computer, a mobile phone, a tablet computer, a smart watch, etc.

[0037] In some embodiments, the sensing element is a sound sensor and generates sensing information according to the ambient volume. The lighting control panel determines whether the volume decibel is higher or lower than a preset volume threshold and controls the working state of the light-emitting unit. For example, when the volume decibel is higher than the preset volume threshold, the lighting control panel controls the light-emitting unit to automatically turn on. Optionally, the lighting control panel controls the light-emitting unit to turn on and maintain it for a certain period of time. When the volume decibel drops to the preset volume threshold, the lighting control panel controls the light-emitting unit to automatically turn off.

[0038] In some embodiments, the light-emitting unit may be configured to provide at least one lighting effect selected from the group consisting of monochromatic lighting, multi-color lighting, continuous lighting, flashing lighting, running light lighting, and breathing light lighting. For example, in a dark environment with low brightness, a high light brightness may cause the user to feel glaring and uncomfortable. In this case, the eye discomfort caused by large changes in light may be alleviated by using color lighting with moderate brightness or breathing light lighting.

[0039] It should be understood that one or more of the various optional embodiments of the above-mentioned sensing unit and the light-emitting unit can be replaced with each other and used in combination to meet different needs of users.

[0040] According to the present invention, the light guide unit is advantageously configured as an operating member outside the housing and is arranged adjacent to the light emitting unit 66 to transmit the light of the light emitting unit 66 to the outside of the housing. In the illustrated embodiment, the light guide unit is a test button 8 of the test assembly. Figure 2 As shown, the light guide unit is arranged close to the light-emitting unit 66. In this way, the light emitted by the light-emitting unit is transmitted to the outside of the housing via a large-area reflective surface, which can achieve a large range of lighting areas and better lighting effects. In addition, since the light guide unit is integrated into the test button, the external structure and size of the product have not changed significantly, and it is still suitable for the normal use of the product.

[0041] It should be understood that the light guide unit can also be integrated into the reset button 7 and the reset button 7 can be made of a light-transmitting material to achieve the same function. In some embodiments, two light-emitting units can be provided on the lighting control board 6 to correspond to the reset button 7 and the test button 8 respectively, so that the lighting function can be achieved through the two operating members, or a variety of lighting effects can be achieved.

[0042] In some embodiments, the test button can be constructed according to conventional designs, and the lighting function can be realized by simply changing the material. Advantageously, the test button 8 can be provided with a structure that enhances light reflection to further enhance the lighting effect. Figure 5 In the illustrated embodiment, the test button 8 is constructed to include a light-guiding key 81 and a reflector 82, wherein the light-guiding key 82 is suitable for protruding out of the shell to form a button portion, and the reflector 82 is engaged with the light-guiding key 81 and has a test rod 823 suitable for contacting the test piece 32 of the test assembly, wherein at least the light-guiding key 81 is made of a light-transmitting material, and the light-transmitting material includes any suitable material of a transparent or translucent material. Optionally, the reflector 82 is engaged with the light-guiding key 81 in a snap-fit ​​connection, wherein the two ends of the light-guiding key 81 are respectively provided with a snap 811 and a bayonet 812, and the two ends of the reflector 82 are respectively provided with a bayonet 821 and a snap 822, so as to be suitable for a detachable connection between the reflector 82 and the light-guiding key 81. In this way, different lighting effects can be obtained by replacing, for example, the material and color of the light-guiding key. In some embodiments, a diffuse reflection bevel 82A can be provided on the reflector 82, and the diffuse reflection bevel 82A is adapted to the shape of the light-guiding key 81 and is opposite to the light-emitting unit, that is, as shown in FIG. Figure 5 As shown, it is arranged toward the direction of incident light, so as to be suitable for diffusely reflecting light through the light-guiding key 81, thereby enhancing the lighting effect.

[0043] When the assembled leakage protection device is put into use, the sensing unit senses or detects the external environment of the product and provides sensing information. The lighting control panel responds to the sensing information to control the light-emitting unit to turn on or off. When the light-emitting unit is turned on, the light emitted is transmitted to the outside of the product through the light-guiding unit (diffuse reflection slope and light-guiding key) to provide lighting, which is convenient for plugging in or out. By setting different sensing units, the leakage protection device can realize multi-mode lighting control, such as light control, voice control, etc., which is convenient for users to use and makes the product more intelligent and user-friendly. In addition, since the lighting component is powered by the movement component, the working status of the leakage protection device can be displayed simply and conveniently when the lighting component is turned on or off.
