Description

Technical Field

[0001] The invention relates to a fixed wall socket or an extension cord socket, in particular to a waterproof and electric shock-proof safety socket. Background Art

[0002] A socket, also known as a power socket or a switch socket, is an electrical device that provides a power interface for electrical appliances. Common sockets in life have two-hole, three-hole or four-hole designs. When the pins of the electrical plug are inserted into the socket, the socket connects the circuit between the electrical appliance and the power supply, allowing the electrical appliance to work normally. However, many existing sockets have many safety hazards in design and use, especially defects in waterproof and anti-electric shock functions.

[0003] First, most common sockets lack waterproof design. Once liquid contacts the socket, it is very easy to cause a short circuit or leakage accident. For example, in a humid environment such as a kitchen or bathroom, water splashing on the socket may cause an electric shock risk. In addition, the insulation performance of some sockets is insufficient and cannot effectively prevent current leakage.

[0004] Secondly, the anti-electric shock function also has obvious defects. 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, causing electric shock accidents. Even if some sockets are equipped with protective doors, their design is not strong enough and is easily damaged, and cannot completely prevent foreign objects from being inserted.

[0005] In addition, some sockets have other safety hazards, such as loose plugs and poor contact of sockets due to insecure installation, which may even cause fires. These problems not only threaten the safety of users, but also bring great risks to homes and public places. Summary of the invention

[0006] The invention provides a waterproof and electric shock-proof safety socket which is simple in structure and safe and reliable.

[0007] The waterproof and electric shock-proof safety socket of the present invention comprises a socket body, the surface of the socket body is provided with a socket hole for inserting the pins of the plug, the position corresponding to the socket hole inside the socket body is installed with a live wire socket and a neutral wire socket for contacting and connecting with the pins, the socket body is provided with an independent live wire independent compartment and a neutral wire independent compartment that are independently separated and elastically deformable, and a slide groove; the live wire independent compartment has a live wire main electrode connected to the live wire of an external power supply, and a live wire elastic sheet connected to the live wire socket is provided on the side of the live wire main electrode; the neutral wire independent compartment has a neutral wire main electrode connected to the neutral wire of the external power supply, and a neutral wire elastic sheet connected to the live wire socket is provided on the side of the neutral wire main electrode A neutral wire elastic sheet connected to the neutral wire socket; a slider that can push the side walls of the live wire independent bin and the neutral wire independent bin to deform horizontally along the slide groove and an elastic member that resets the slider are installed on the outside of the live wire independent bin and the neutral wire independent bin, and an inclined surface is provided at the position of the slider relative to the socket hole. When the pin of the power plug is inserted into the socket hole, the pin will press the inclined surface to push the slider to move horizontally until it abuts against the outside of the live wire independent bin and the neutral wire independent bin. At this time, the side walls of the live wire independent bin and the neutral wire independent bin are elastically deformed until the live wire elastic sheet in the live wire independent bin is in contact with the live wire main electrode and the neutral wire elastic sheet in the neutral wire independent bin is in contact with the neutral wire main electrode.

[0008] The waterproof and electric shock-proof safety socket achieves electrical isolation through the independently separated live wire independent compartment and neutral wire independent compartment, effectively avoiding the risk of short circuit between the live wire and the neutral wire, and also avoiding the generation of arc sparks at the socket port during the plugging and unplugging process, significantly reducing the risk of electrical fire caused by plugging and unplugging operations, thereby greatly improving the safety of the socket. At the same time, before the plug is inserted into the socket hole and the slider is pushed, the slider can also play the role of shielding the socket hole, which can prevent water droplets from entering and improve the waterproof performance. In addition, the slider only pushes the side walls of the live wire independent compartment and the neutral wire independent compartment when the plug pin is correctly inserted, so that the live wire elastic sheet and the live wire main electrode, and the neutral wire elastic sheet and the neutral wire main electrode are in contact and conductive, effectively preventing the hidden danger of leakage when the plug is not fully inserted. At the same time, the elastic deformation structure of the live wire independent compartment and the neutral wire independent compartment is combined with the contact mechanism of the slider and the elastic sheet, which reduces the direct friction between the components, reduces wear, and significantly extends the overall service life of the socket. The present invention has a simple structure, and the live wire independent chamber and the neutral wire independent chamber separate the live wire and neutral wire electrodes in independent chambers. When the plug is not inserted, the live wire elastic sheet and the live wire main electrode, and the neutral wire elastic sheet and the neutral wire main electrode are in an isolated state, which effectively prevents electric shock accidents caused by accidental touching of the electrodes and improves the safety of the socket. Through the arrangement of the slider and the elastic part, the slider can be pushed by the inclined surface when the plug is inserted, so as to realize the elastic deformation of the side wall of the independent chamber, and then promote the contact and conduction between the live wire elastic sheet and the live wire main electrode, and the neutral wire elastic sheet and the neutral wire main electrode, which not only ensures the smoothness of the plug insertion, but also ensures that the electrodes can automatically restore to the isolated state after the plug is pulled out through the reset function of the elastic part, further enhancing the safety against electric shock.

[0009] As a preferred solution of the present invention, the surface of the socket body is provided with a three-hole socket hole adapted for inserting a three-position plug and a two-hole socket hole adapted for inserting a two-position plug, the live wire socket includes a three-position live wire socket and a two-position live wire socket, the neutral wire socket includes a three-position neutral wire socket and a two-position neutral wire socket, the live wire elastic sheet includes a three-position live wire elastic sheet and a two-position live wire elastic sheet arranged 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 arranged on both sides of the neutral wire main electrode, the slide groove is laterally located between the live wire independent bin and the neutral wire independent bin, the elastic member is installed in the slide groove and abuts against the slider, the slider includes a three-position slider slidably installed at one end of the slide groove corresponding to the three-position plug and a two-position slider slidably installed at the other end of the slide groove corresponding to the two-position plug.

[0010] As a preferred solution of the present invention, one end of the slider used to push the live wire independent compartment and the neutral wire independent compartment to elastically deform is provided with a U-shaped elastic foot.

[0011] As a preferred solution of the present invention, a waterproof rubber pad is further installed in the socket body below the socket hole, and a cutout for the pin to pass through is arranged at a position of the waterproof rubber pad corresponding to the socket hole.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, "several" means more than one, "many" means more than two, and "above", "below", "within", etc. are all understood to include the number. In addition, the technical features of each embodiment can be arbitrarily combined. In order to make the description concise, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0024] like Figure 1-5As shown, a waterproof and electric shock-proof safety socket comprises a socket body 1, a socket hole 3 for inserting a plug pin 2 of a plug is provided on the surface of the socket body, a live wire socket 4 and a neutral wire socket 5 for contacting and connecting with the plug pin are installed at positions corresponding to the socket hole inside the socket body, and an independent live wire compartment 6 and a neutral wire compartment 7 which are independently separated and elastically deformable, as well as a slide groove 8 are provided inside the socket body; a live wire main electrode 9 connected to the live wire of an external power supply is built in the live wire independent compartment, and a live wire elastic sheet 10 connected to the live wire socket 4 is provided on the side of the live wire main electrode; a neutral wire main electrode 11 connected to the neutral wire of an external power supply is built in the neutral wire independent compartment, and a neutral wire elastic sheet 10 connected to the live wire socket 4 is provided on the side of the live wire main electrode; a neutral wire main electrode 11 connected to the neutral wire of an external power supply is built in the neutral wire independent compartment, and a neutral wire elastic sheet 10 connected to the live wire socket 4 is provided on the side of the neutral wire main electrode A neutral wire elastic sheet 12 connected to the neutral wire socket 5 is provided; a slider 13 which can push the side walls of the live wire independent bin and the neutral wire independent bin to deform horizontally along the slide groove and an elastic member 14 for resetting the slider are installed on the outer sides of the live wire independent bin and the neutral wire independent bin, and a slope 15 is provided at the position of the slider relative to the socket hole. When the pin of the power plug is inserted into the socket hole, the pin will press the slope to push the slider to move horizontally until it abuts against the outer sides of the live wire independent bin and the neutral wire independent bin. At this time, the side walls of the live wire independent bin and the neutral wire independent bin are elastically deformed until the live wire elastic sheet in the live wire independent bin is in contact with the live wire main electrode and the neutral wire elastic sheet in the neutral wire independent bin is in contact with the neutral wire main electrode. The waterproof and electric shock-proof safety socket achieves electrical isolation through the independently separated live wire independent compartment and neutral wire independent compartment, effectively avoiding the risk of short circuit between the live wire and the neutral wire, and also avoiding the generation of arc sparks at the socket port during the plugging and unplugging process, significantly reducing the risk of electrical fire caused by plugging and unplugging operations, thereby greatly improving the safety of the socket. At the same time, before the plug is inserted into the socket hole and the slider is pushed, the slider can also play the role of shielding the socket hole, which can prevent water droplets from entering and improve the waterproof performance. In addition, the slider only pushes the side walls of the live wire independent compartment and the neutral wire independent compartment when the plug pin is correctly inserted, so that the live wire elastic sheet and the live wire main electrode, and the neutral wire elastic sheet and the neutral wire main electrode are in contact and conductive, effectively preventing the hidden danger of leakage when the plug is not fully inserted. At the same time, the elastic deformation structure of the live wire independent compartment and the neutral wire independent compartment is combined with the contact mechanism of the slider and the elastic sheet, which reduces the direct friction between the components, reduces wear, and significantly extends the overall service life of the socket. The present invention has a simple structure, and the live wire independent chamber and the neutral wire independent chamber separate the live wire and neutral wire electrodes in independent chambers. When the plug is not inserted, the live wire elastic sheet and the live wire main electrode, and the neutral wire elastic sheet and the neutral wire main electrode are in an isolated state, which effectively prevents electric shock accidents caused by accidental touching of the electrodes and improves the safety of the socket. Through the arrangement of the slider and the elastic part, the slider can be pushed by the inclined surface when the plug is inserted, so as to realize the elastic deformation of the side wall of the independent chamber, and then promote the contact and conduction between the live wire elastic sheet and the live wire main electrode, and the neutral wire elastic sheet and the neutral wire main electrode, which not only ensures the smoothness of the plug insertion, but also ensures that the electrodes can automatically restore to the isolated state after the plug is pulled out through the reset function of the elastic part, further enhancing the safety against electric shock.

[0025] 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 socket includes a three-position live wire socket and a two-position live wire socket, the neutral wire socket includes a three-position neutral wire socket and a two-position neutral wire socket, the live wire elastic sheet includes a three-position live wire elastic sheet and a two-position live wire elastic sheet arranged 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 arranged on both sides of the neutral wire main electrode, the slide groove is transversely located between the live wire independent bin and the neutral wire independent bin, the elastic member is installed in the slide groove and abuts against the slider, the slider includes a three-position slider slidably installed at one end of the slide groove corresponding to the three-position plug and a two-position slider slidably installed at the other end of the slide groove corresponding to the two-position plug. The surface of the socket body is provided with a three-hole socket hole and a two-hole socket hole, which are adapted to the three-position plug and the two-position plug respectively, so that the socket can meet the use requirements of different types of plugs at the same time, and improve the versatility and applicability of the socket. The slide groove is horizontally arranged between the live wire independent bin and the neutral wire independent bin, providing a stable guide for the movement of the slider, ensuring that the slider can move smoothly and accurately during the pushing process, avoiding poor contact or jamming problems caused by poor sliding.

[0026] The slider 13 is provided with a U-shaped elastic foot 16 at one end thereof for pushing the live wire independent chamber and the neutral wire independent chamber to elastically deform. The U-shaped elastic foot can provide good elastic deformation capability. When the plug is inserted, the U-shaped elastic foot can disperse the force more evenly through its shape, thereby maintaining stable and reliable contact when pushing the live wire independent chamber and the neutral wire independent chamber 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 rubber pad 17 is also installed below the socket hole in the socket body, and a cutout 18 for the pin to pass through is arranged at a position corresponding to the socket hole. The waterproof rubber pad has waterproof and dustproof effects, and a cutout is formed by a secondary cutting and breaking process at the position corresponding to the socket, so that the socket is in a closed state when no plug is inserted, which can effectively prevent dust, small spiders, mosquitoes and other creatures from entering the socket, and can avoid the deterioration of the insulation effect caused by the accumulation of foreign matter for a long time, thereby reducing the risk of safety accidents such as leakage and fire.

[0028] 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 19. The silver contacts have extremely high conductivity, can significantly reduce contact resistance, ensure the efficiency and stability of current transmission, and show good wear resistance in long-term use, which can reduce surface wear caused by frequent disconnection of contact.

[0029] The elastic member is a spring.

[0030] The live wire independent chamber and the neutral wire independent chamber are made of high temperature resistant and elastic silicone rubber material, which not only has excellent heat resistance, but also has excellent electrical insulation performance, good elasticity and resistance to compression deformation, and excellent waterproof performance.

[0031] Specifically, the socket body also includes some structures of the prior art, such as a safety structure body 20 in which a sealed chamber can be formed by a seal inside the socket body, wherein an independent live wire compartment, an independent neutral wire compartment, a slide groove, a slider, a live wire socket and a neutral wire socket are all arranged in the safety structure body, a waterproof rubber pad is installed in the front of the safety structure body, and a 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, and the live wire main electrode, the neutral wire main electrode, the two-position live wire elastic sheet, the two-position neutral wire elastic sheet, the three-position live wire elastic sheet, the three-position neutral wire elastic sheet, the live wire socket and the neutral wire socket pass through the rear pressure cover from the back of the safety structure body to expose the ends, thereby improving the waterproof performance of the entire socket.

[0032] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
