Abstract
Description
Technical Field
[0001] This utility model relates to a fixed wall socket or extension cord socket, specifically a waterproof and shockproof safety socket. Background Technology
[0002] A power outlet, also known as a power socket or switch socket, is an electrical device that provides a power interface for electrical appliances. Commonly used outlets in daily life have two, three, or four prongs. When the prongs of an appliance plug are inserted into the prongs of the outlet, the outlet connects the appliance to the power source, allowing the appliance to function properly. However, many existing outlets have numerous safety hazards in their design and use, especially deficiencies in waterproofing and protection against electric shock.
[0003] First, most ordinary sockets lack waterproof design. Once liquid comes into contact with the socket, it can easily cause short circuits or electric leakage accidents. For example, in humid environments such as kitchens or bathrooms, water splashed on the socket may pose a risk of electric shock. In addition, some sockets have insufficient insulation performance and cannot effectively prevent current leakage.
[0004] Secondly, the anti-electric shock function also has obvious deficiencies. Many sockets are not equipped with effective child safety protection devices, which may cause children to insert conductive objects such as fingers, keys, and nails into the sockets out of curiosity, thus causing electric shock accidents. Even if some sockets are equipped with safety shutters, their design is not sturdy enough and they are easily damaged, failing to completely prevent the insertion of foreign objects.
[0005] In addition, some sockets pose other safety hazards, such as loose installation leading to loose plugs, poor contact in the sockets, and even the potential for fire. These problems not only threaten the safety of users but also pose significant risks to homes and public places. Utility Model Content
[0006] This utility model provides a waterproof and electric shock-proof safety socket with a simple structure and reliable safety.
[0007] The waterproof and shockproof safety socket of this utility model includes a socket body. The surface of the socket body has socket holes for inserting plug prongs. Inside the socket body, corresponding to the socket holes, are installed live wire sleeves and neutral wire sleeves for contact and connection with the prongs. The socket body contains independently separated and elastically deformable live wire compartments and neutral wire compartments, as well as a sliding groove. The live wire compartment houses the main live wire electrode connected to the external power supply's live wire, and a live wire elastic piece connected to the live wire sleeve is provided on the side of the main live wire electrode. The neutral wire compartment houses the main neutral wire electrode connected to the external power supply's neutral wire, and a neutral wire elastic piece is provided on the side of the main neutral wire electrode. A neutral wire elastic piece is placed and connected to the neutral wire socket. A slider that can be horizontally pushed along the slide groove to deform the side walls of the live wire independent compartment and the neutral wire independent compartment, as well as an elastic element that resets the slider, are installed on the outside of the live wire independent compartment and the neutral wire independent compartment. The slider has an inclined surface at the position of the position of the socket hole. When the plug of the power plug is inserted into the socket hole, the plug will press the inclined surface and push the slider to move horizontally to abut against the outside of the live wire independent compartment and the neutral wire independent compartment. At this time, the side walls of the live wire independent compartment and the neutral wire independent compartment undergo elastic deformation until the live wire elastic piece in the live wire independent compartment contacts the live wire main electrode and conducts electricity, and the neutral wire elastic piece in the neutral wire independent compartment contacts the neutral wire main electrode and conducts electricity.
[0008] The aforementioned waterproof and shockproof safety socket achieves electrical isolation through independently separated live wire and neutral wire compartments, effectively avoiding the risk of short circuits between the live and neutral wires. It also prevents electric arcs at the socket opening during insertion and removal, significantly reducing the risk of electrical fires caused by insertion and removal operations, thus greatly improving the socket's safety. Furthermore, before the plug is inserted into the socket hole and the slider is pushed, the slider can also block the socket hole, preventing water droplets from entering and enhancing waterproof performance. In addition, the slider only pushes the side walls of the live and neutral wire compartments when the plug prongs are correctly inserted, ensuring contact and conductivity between the live wire elastic piece and the live wire main electrode, and between the neutral wire elastic piece and the neutral wire main electrode, effectively preventing leakage hazards caused by accidental contact or incomplete plug insertion. Simultaneously, the elastic deformation structure of the live and neutral wire compartments, combined with the contact mechanism of the slider and elastic pieces, reduces direct friction between components, lowers wear, and significantly extends the overall service life of the socket. This utility model features a simple structure with separate compartments for the live and neutral wires, effectively isolating the live and neutral wire electrodes when the plug is not inserted. This isolates the live wire elastic plate from the live wire main electrode and the neutral wire elastic plate from the neutral wire main electrode, thus preventing accidental electric shock and improving socket safety. Furthermore, the slider and elastic element allow the slider to be pushed by the inclined surface when the plug is inserted, causing elastic deformation of the side wall of the independent compartment. This, in turn, facilitates contact between the live wire elastic plate and the live wire main electrode, and between the neutral wire elastic plate and the neutral wire main electrode. This not only ensures smooth plug insertion but also, through the reset function of the elastic element, guarantees that the electrodes automatically return to an isolated state after the plug is removed, further enhancing safety against electric shock.
[0009] As a preferred embodiment of this utility model, the surface of the socket body is provided with a three-hole socket hole adapted for the insertion of a three-position plug and a two-hole socket hole adapted for the insertion of a two-position plug. The live wire sleeve includes a three-position live wire sleeve and a two-position live wire sleeve. The neutral wire sleeve includes a three-position neutral wire sleeve and a two-position neutral wire sleeve. The live wire elastic sheet includes a three-position live wire elastic sheet and a two-position live wire elastic sheet disposed on both sides of the live wire main electrode. The neutral wire elastic sheet includes a three-position neutral wire elastic sheet and a two-position neutral wire elastic sheet disposed on both sides of the neutral wire main electrode. The sliding groove is laterally located between the live wire independent compartment and the neutral wire independent compartment. The elastic element is installed in the sliding groove and abuts against the slider. The slider includes a three-position slider corresponding to the three-position plug and slidably installed at one end of the sliding groove and a two-position slider corresponding to the two-position plug.
[0010] As a preferred embodiment of this utility model, the slider is provided with a U-shaped elastic foot at one end for pushing the live wire independent compartment and the neutral wire independent compartment to deform elastically.
[0011] As a preferred embodiment of this utility model, a waterproof rubber pad is also installed inside the socket body below the socket hole, and the waterproof rubber pad is provided with a cut for the plug pins to pass through at the position corresponding to the socket hole.
[0012] As a preferred embodiment of this utility model, the ends of the live wire main electrode, the neutral wire main electrode, the live wire elastic sheet, and the neutral wire elastic sheet are all provided with silver contacts.
[0013] In a preferred embodiment of this utility model, the elastic element is a spring.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] like Figure 1-5As shown, a waterproof and shockproof safety socket includes a socket body 1. The surface of the socket body has socket holes 3 for inserting plug prongs 2. Inside the socket body, corresponding to the socket holes, are installed live wire sleeves 4 and neutral wire sleeves 5 for contacting the prongs. The socket body also has independently separated and elastically deformable live wire compartments 6 and 7, as well as a sliding groove 8. The live wire compartment houses a main live wire electrode 9 connected to an external power supply live wire, and a live wire elastic piece 10 connected to the live wire sleeve 4 is provided on the side of the main live wire electrode. The neutral wire compartment houses a main neutral wire electrode 11 connected to an external power supply neutral wire, and a neutral wire elastic piece 10 connected to the neutral wire sleeve 4 is provided on the side of the main neutral wire electrode. A neutral wire elastic piece 12 is provided and connected to the neutral wire socket 5; a slider 13 is installed on the outside of the live wire independent compartment and the neutral wire independent compartment, which can be pushed horizontally along the slide groove to deform the side walls of the live wire independent compartment and the neutral wire independent compartment, and an elastic element 14 is provided to reset the slider. The slider is provided with an inclined surface 15 at the position of the socket hole. When the plug of the power plug is inserted into the socket hole, the plug will press the inclined surface and push the slider to move horizontally to abut against the outside of the live wire independent compartment and the neutral wire independent compartment. At this time, the side walls of the live wire independent compartment and the neutral wire independent compartment undergo elastic deformation until the live wire elastic piece in the live wire independent compartment contacts the live wire main electrode and conducts electricity, and the neutral wire elastic piece in the neutral wire independent compartment contacts the neutral wire main electrode and conducts electricity. The aforementioned waterproof and shockproof safety socket achieves electrical isolation through independently separated live wire and neutral wire compartments, effectively avoiding the risk of short circuits between the live and neutral wires. It also prevents electric arcs at the socket opening during insertion and removal, significantly reducing the risk of electrical fires caused by insertion and removal operations, thus greatly improving the socket's safety. Furthermore, before the plug is inserted into the socket hole and the slider is pushed, the slider can also block the socket hole, preventing water droplets from entering and enhancing waterproof performance. In addition, the slider only pushes the side walls of the live and neutral wire compartments when the plug prongs are correctly inserted, ensuring contact and conductivity between the live wire elastic piece and the live wire main electrode, and between the neutral wire elastic piece and the neutral wire main electrode, effectively preventing leakage hazards caused by accidental contact or incomplete plug insertion. Simultaneously, the elastic deformation structure of the live and neutral wire compartments, combined with the contact mechanism of the slider and elastic pieces, reduces direct friction between components, lowers wear, and significantly extends the overall service life of the socket. This utility model features a simple structure with separate compartments for the live and neutral wires, effectively isolating the live and neutral wire electrodes when the plug is not inserted. This isolates the live wire elastic plate from the live wire main electrode and the neutral wire elastic plate from the neutral wire main electrode, thus preventing accidental electric shock and improving socket safety. Furthermore, the slider and elastic element allow the slider to be pushed by the inclined surface when the plug is inserted, causing elastic deformation of the side wall of the independent compartment. This, in turn, facilitates contact between the live wire elastic plate and the live wire main electrode, and between the neutral wire elastic plate and the neutral wire main electrode. This not only ensures smooth plug insertion but also, through the reset function of the elastic element, guarantees that the electrodes automatically return to an isolated state after the plug is removed, further enhancing safety against electric shock.
[0025] The socket body surface is provided with a three-hole socket for three-position plugs and a two-hole socket for two-position plugs. The live wire sleeve includes a three-position live wire sleeve and a two-position live wire sleeve; the neutral wire sleeve includes a three-position neutral wire sleeve and a two-position neutral wire sleeve; the live wire elastic piece includes a three-position live wire elastic piece and a two-position live wire elastic piece disposed on both sides of the live wire main electrode; the neutral wire elastic piece includes a three-position neutral wire elastic piece and a two-position neutral wire elastic piece disposed on both sides of the neutral wire main electrode. The sliding groove is laterally located between the live wire independent compartment and the neutral wire independent compartment. The elastic element is installed in the sliding groove and abuts against the slider. The slider includes a three-position slider corresponding to a three-position plug and a two-position slider corresponding to a two-position plug, slidably installed at one end of the sliding groove. The socket body surface is provided with three-hole and two-hole sockets to accommodate three-position and two-position plugs respectively, enabling the socket to simultaneously meet the usage requirements of different types of plugs, improving the socket's versatility and applicability. The slide is horizontally positioned between the live wire independent compartment and the neutral wire independent compartment, providing a stable guide for the movement of the slider. This ensures that the slider can move smoothly and accurately during the pushing process, avoiding problems such as poor contact or jamming caused by poor sliding.
[0026] The slider 13, used to push the independent live wire compartment and the independent neutral wire compartment to deform elastically, has a U-shaped elastic foot 16 at one end. The U-shaped elastic foot provides good elastic deformation capability. When the plug is inserted, the U-shaped elastic foot can distribute the force more evenly due to its shape, thereby maintaining stable and reliable contact when pushing the independent live wire compartment and the independent neutral wire compartment to deform. In addition, the U-shaped elastic foot also effectively solves the problem of poor contact caused by manufacturing tolerances and wear after long-term use, significantly improving the durability and reliability of the socket.
[0027] A waterproof gasket 17 is installed inside the socket body below the socket hole. A cut 18 is provided on the waterproof gasket at the position corresponding to the socket hole for the plug pins to pass through. The waterproof gasket serves to prevent water and dust penetration. The cut 18 is created by a secondary cutting process at the corresponding socket hole position, ensuring the socket is closed when no plug is inserted. This effectively prevents dust, small spiders, insects, and other organisms from entering the socket, avoiding a decrease in insulation performance due to the accumulation of foreign objects over time, thereby reducing the risk of electrical leakage, fire, and other safety accidents.
[0028] The ends of the live wire main electrode, neutral wire main electrode, live wire elastic sheet, and neutral wire elastic sheet are all provided with silver contacts 19. The silver contacts have extremely high conductivity, which can significantly reduce contact resistance, ensure efficient and stable current transmission, and also exhibit good wear resistance during long-term use, reducing surface wear caused by frequent disconnection.
[0029] The elastic element is a spring.
[0030] The independent live wire compartment and the independent neutral wire compartment are made of high-temperature resistant and elastic silicone rubber, which not only has excellent heat resistance, but also excellent electrical insulation, good elasticity and resistance to compression deformation, as well as excellent waterproof performance.
[0031] Specifically, the socket body also includes some existing technology structures, such as a safety structure body 20 that can form a sealed chamber inside the socket body through a sealing element. Its independent live wire compartment, independent neutral wire compartment, slide groove, slider, live wire socket and neutral wire socket are all set in the safety structure body. A waterproof rubber gasket is installed on the front of the safety structure body. The rear pressure cover 21 for installing and fixing the live wire main electrode and the neutral wire main electrode is installed on the back of the safety structure body. The live wire main electrode, neutral wire main electrode, two-position live wire elastic sheet, two-position neutral wire elastic sheet, three-position live wire elastic sheet, three-position neutral wire elastic sheet, live wire socket and neutral wire socket pass through the rear pressure cover from the back of the safety structure body and protrude from the end, thereby improving the waterproof performance of the entire socket.
