Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a double - protection anti - electric - shock socket. Background Art

[0002] With the improvement of people's living standards, the types and quantities of household appliances are increasing continuously, and the problem of household electricity safety has become increasingly prominent. Among them, electric shock accidents are one of the common household electricity safety hazards. For example, for children, their safety awareness is weak, and they may insert conductive objects into the socket jacks, resulting in electric shock accidents. Another example is that sometimes when people insert the plug into the socket, when the connector has not fully entered the socket but has already connected to the socket power supply, if the hand touches the exposed connector at this time, electric shock will occur.

[0003] In summary, the existing sockets are prone to electric shock when children accidentally insert conductive objects, and at the same time, since the connector of the plug can be energized without being fully inserted, it is also easy to cause electric shock. Content of the Utility Model

[0004] Aiming at the technical problems existing in the prior art, the purpose of the utility model is to provide a double - protection anti - electric - shock socket, which solves the problems that the existing sockets are prone to electric shock when children accidentally insert conductive objects, and at the same time, since the connector of the plug can be energized without being fully inserted, it is also easy to cause electric shock.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A double - protection anti - electric - shock socket, comprising: a socket body, which is internally provided with a first support shaft and a second support shaft. The live wire connector of the socket body is divided into a first live - wire connection section, a second live - wire connection section and a third live - wire connection section, and the first live - wire connection section, the second live - wire connection section and the third live - wire connection section are arranged at intervals; a first swing plate, which is rotatably connected to the first support shaft to form a first lever structure with the first support shaft as the fulcrum; one end of the first swing plate is used for contacting the neutral wire connector of the plug, and the other end of the first swing plate is used for connecting the first live - wire connection section and the second live - wire connection section; a second swing plate, which is rotatably connected to the second support shaft to form a second lever structure with the second support shaft as the fulcrum; one end of the second swing plate is used for contacting the live wire connector of the plug, and the other end of the second swing plate is used for connecting the second live - wire connection section and the third live - wire connection section.

[0007] As a preference, the double - protection anti - electric - shock socket further comprises a rotary cover, which is rotatably connected to the socket body. The rotary cover covers the jacks of the socket body, and the rotary cover is provided with docking holes corresponding to the jacks of the socket body.

[0008] As a preference, an installation groove recessed into the socket body is provided at the jack of the socket body, and the rotary cover is embedded in the installation groove and can rotate relative to the installation groove.

[0009] As a preference, a limiting groove recessed into the socket body is provided on the installation groove, a limiting plate is provided on the rotary cover, the limiting plate is inserted into the limiting groove, and the limiting plate is slidably connected to the limiting groove.

[0010] As a preference, a force-bearing block is provided on the limiting plate, the force-bearing block is fixedly connected with a compression spring, and the compression spring contacts with the end of the limiting groove.

[0011] As a preference, the distance between one end of the first swing plate and the jack of the socket body is a, and the distance between the other end of the first swing plate and the first live wire connection section or the second live wire connection section is b, and a - b ≤ 2 mm.

[0012] As a preference, a first return spring is provided in the socket body, one end of the first return spring is fixedly connected with the inner wall of the socket body, and the other end of the first return spring is fixedly connected with the other end of the first swing plate.

[0013] As a preference, a second return spring is provided in the socket body, one end of the second return spring is fixedly connected with the inner wall of the socket body, and the other end of the second return spring is fixedly connected with the other end of the second swing plate.

[0014] Generally speaking, the present utility model has the following advantages:

[0015] 1. For the double-protection anti-electric shock socket of the present utility model, the lever principle (seesaw-type mechanical structure design) is applied, so that the zero-line joint and the live-line joint of the plug must be inserted in place simultaneously to make the live wire in the socket body that is open-circuited conduct electricity in series. If a single joint is inserted or not inserted in place, the circuit cannot be connected, effectively protecting the safety of users, especially avoiding improper operations of children and the elderly, and increasing the reliability of anti-electric shock.

[0016] 2. For the double-protection anti-electric shock socket of the present utility model, the rotary cover on the socket panel is designed to cover the jack of the socket, preventing dust and small particles from falling into the jack, which may cause electric arcs and lead to short circuits or open circuits. When in use, the circular rotary cover must be rotated by an angle with the help of the joint of the plug to insert the joint of the plug into the jack of the socket, which can prevent children from directly inserting foreign objects into the jack and causing electric shock. When not inserted, the knob resets under the action of the spring force and covers the jack of the socket. Description of the Drawings

Specific implementation mode

[0025] The following will further elaborate on the present utility model in combination with the specific implementation mode.

[0026] As Figures 1 - 7 shown, a double - protection anti - electric shock socket provided in this embodiment includes:

[0027] The socket body 1, which is internally provided with a first support shaft 14 and a second support shaft 15; the socket body 1 is an existing power socket installed on the wall, and its jack 4 can be two - hole and three - hole, or both two - hole and three - hole can be set on the power socket. Both the first support shaft 14 and the second support shaft 15 are cylindrical shaft - body structures. By arranging two erected plastic plates in the socket body and setting connection holes on the plastic plates, the first support shaft 14 is fixedly connected to the connection holes on the two erected plastic plates. If the first swing plate 12 is fixedly connected to the first support shaft 14, then the first support shaft 14 and the connection hole are rotationally connected, and vice versa; similarly, the setting method of the second support shaft 15 is the same as that of the first support shaft 14. The live - wire connector of the socket body is divided into a first live - wire connection section 17, a second live - wire connection section 18, and a third live - wire connection section 16, and the first live - wire connection section 17, the second live - wire connection section 18, and the third live - wire connection section 16 are arranged at intervals; the setting of the neutral - wire and ground - wire connectors in the socket body is the same as the existing one, and will not be elaborated here too much.

[0028] The first swing plate 12 is rotatably connected to the first support shaft 14 to form a first lever structure with the first support shaft 14 as the fulcrum; one end of the first swing plate 12 is used to contact the neutral wire joint of the plug, and the other end of the first swing plate 12 is used to connect the first live wire connection section 17 and the second live wire connection section 18, so that the first live wire connection section 17 and the second live wire connection section 18 are in series; metal plates capable of conducting electricity are inlaid at the places where the first swing plate 12 contacts the first live wire connection section and the second live wire connection section. When the neutral wire joint of the plug is inserted into the socket body 1 from outside the socket body 1, the neutral wire joint of the plug squeezes the first swing plate 12 and swings towards the bottom of the socket body 1, so that the other end of the first swing plate 12 is lifted to contact the first live wire connection section 17 and the second live wire connection section 18. Through the first support shaft 14, the first swing plate 12 can swing like a seesaw. If one end of the first swing plate 12 is squeezed by the neutral wire joint of the plug to a certain extent and other circuits are all connected (the second live wire connection section 18 and the third live wire connection section 16, the neutral wire and the ground wire are all connected), but the other end of the first swing plate 12 does not contact the first live wire connection section 17 and the second live wire connection section 18, then there will be no power supply. Only when the first swing plate 12 contacts both the first live wire connection section 17 and the second live wire connection section 18 and other circuits are all connected, will there be power supply. This can avoid the problem that the joint of the plug is not fully inserted into the socket for power supply, and the joint of the plug is exposed outside, which is easy to cause electric shock.

[0029] The second swing plate 13 is rotatably connected to the second support shaft 15 to form a second lever structure with the second support shaft 15 as the fulcrum; one end of the second swing plate 13 is used to contact the live wire joint of the plug, and the other end of the second swing plate 13 is used to connect the second live wire connection section 18 and the third live wire connection section 16, so that the second live wire connection section 18 and the third live wire connection section 16 are in series. Metal plates capable of conducting electricity are inlaid in the area where the second swing plate 13 contacts the second live wire connection section and the third live wire connection section. When the live wire joint of the plug is inserted into the socket body 1 from outside the socket body 1, the live wire joint of the plug squeezes the second swing plate 13 and swings towards the bottom of the socket body 1, so that the other end of the second swing plate 13 is lifted to contact the second live wire connection section 18 and the third live wire connection section 16. The power supply conditions are the same as those of the first swing plate 12, and will not be elaborated here.

[0030] The distance between one end of the first swing plate 12 and the jack 4 of the socket body 1 is a, and the distance between the other end of the first swing plate 12 and the first live wire connection section 17 or the second live wire connection section of the socket body 1 is b, where a - b ≤ 2 mm. The first live wire connection section 17 and the second live wire connection section are in the same plane. Therefore, as long as the other end of the first swing plate 12 is connected to either the first live wire connection section 17 or the second live wire connection section, that is, the other end of the first swing plate 12 is in communication with the first live wire connection section 17 and the second live wire connection section. By setting it like this, the safety of the double - protection anti - electric shock socket can be further ensured. Only when the connector of the plug is almost completely inserted into the socket, that is, within a range of less than 2 mm remaining of the connector, can the power be turned on. And at this distance, the user's hand generally cannot touch the connector of the plug, which can avoid misoperation or electric shock of the blind.

[0031] A first return spring is provided inside the socket body 1. One end of the first return spring is fixedly connected to the inner wall of the socket body 1, and the other end of the first return spring is fixedly connected to the other end of the first swing plate 12. By providing the first return spring, after the connector of the plug is pulled out from the socket, the first return spring resets the first swing plate 12, causing the first swing plate 12 to move away from the first live wire connection section 17 of the socket body 1.

[0032] A second return spring is provided inside the socket body 1. One end of the second return spring is fixedly connected to the inner wall of the socket body 1, and the other end of the second return spring is fixedly connected to the other end of the second swing plate 13. By providing the second return spring, after the connector of the plug is pulled out from the socket, the second return spring resets the second swing plate 13, causing the second swing plate 13 to move away from the third live wire connection section 16 of the socket body 1.

[0033] It should be noted that in the above - mentioned embodiment, only when the two connectors (live wire connector and neutral wire connector) of the plug are completely inserted into the bottom of the socket, the first swing plate 12 and the second swing plate 13 are both activated at the same time, and the first live wire connection section, the second live wire connection section and the third live wire connection section of the live wire form a series connection and are then turned on. A single connector touching the bottom cannot turn on the circuit, which also avoids electric shock caused by misoperation of the insertion method such as inserting obliquely, or poor quality of the connectors, different lengths, etc.

[0034] In some embodiments, the dual - protection electric - shock - proof socket further includes a rotary cover 2. The rotary cover 2 is rotatably connected to the socket body 1. The rotary cover 2 covers the jacks 4 of the socket body 1, and the rotary cover 2 is provided with docking holes 8 corresponding to the jacks 4 of the socket body 1. Specifically, the socket body is provided with a rotary hole 6, and the rotary cover is provided with a rotary shaft 9. The rotary shaft 9 is inserted into the rotary hole 6 and is rotatably connected thereto. By providing the rotary cover 2, before inserting the plug into the socket, it is necessary to first rotate the rotary cover 2 so that the docking holes 8 correspond to the jacks 4. Only then can the connector of the plug be inserted into the socket. Otherwise, the rotary cover covers the jacks, preventing other objects from coming into contact with the jacks.

[0035] At the jacks 4 of the socket body 1, there is an installation groove 3 recessed into the socket body 1. The rotary cover 2 is embedded in the installation groove 3, and the rotary cover 2 can rotate relative to the installation groove 3, that is, the rotary hole 6 is provided in the installation groove. By providing the installation groove 3, the rotary cover 2 can be restricted within the installation groove 3, making it not easy to fall off or be misaligned.

[0036] The installation groove 3 is provided with a limiting groove 5 recessed into the socket body 1. The rotary cover 2 is provided with a limiting plate 10. The limiting plate 10 is inserted into the limiting groove 5, and the limiting plate 10 is slidably connected to the limiting groove 5. By providing the limiting groove 5 in cooperation with the limiting plate 10, the rotary cover 2 can only rotate along a fixed route and within a certain range of motion, facilitating the user to align the docking holes 8 of the rotary cover 2 with the jacks 4.

[0037] The limiting plate 10 is provided with a force - receiving block 11. The force - receiving block 11 is fixedly connected with a compression spring, and the compression spring contacts the end of the limiting groove 5. To facilitate the installation of the force - receiving block 11, an embedding groove 7 is provided at the installation groove 3. The embedding groove 7 is located on one side of the limiting groove 5, so that the force - receiving block 11 connected to the limiting plate 10 can be embedded into the socket body 1 from the embedding groove 7 to avoid interference. By providing the compression spring, after the user pulls out the socket, the rotary cover 2 is pushed by the compression spring to rotate back to its original position, causing the docking holes 8 to be misaligned with the jacks 4 of the socket body 1.

[0038] By providing the rotary cover 2, it is possible to prevent dust and small particles from falling into the jacks 4, which may cause electric arcs, resulting in short - circuits or open - circuits. During use, it is necessary to rotate the circular rotary cover 2 by an angle with the connector of the plug to insert the connector of the plug into the jacks 4 of the socket, which can prevent children from directly inserting foreign objects into the jacks 4 and getting an electric shock. When not inserted, the rotary knob is reset under the action of the compression spring force, covering the jacks 4 of the socket.

[0039] In the above - mentioned embodiments, the connectors of the plug are the live - wire copper sheet, neutral - wire copper sheet, and ground - wire copper sheet of the plug.

[0040] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
