[0035] Please refer to Figures 1 to 13The present invention proposes a safety socket, comprising a shell 100 and a protective partition 200; the shell 100 comprises a top shell 110 and a bottom shell 120, the top shell 110 is provided with jacks, the jacks comprising a live wire jack 111, a neutral wire jack 112 and a ground wire jack 113; the protective partition 200 is arranged between the power plug and the top shell 110; a protective door assembly 300 and a reset mechanism are provided between the protective partition 200 and the top shell 110; the protective door assembly 300 comprises a ground wire protective door 330 and a live wire protective door 310, the reset mechanism is connected to the ground wire protective door 330; a first longitudinal partition 210 is provided above the protective partition 200, the ground wire protective door 330 and the live wire protective door 310 are respectively located at the first longitudinal partition 210 on both sides; the ground wire protection door 330 has a pushing slope for sliding under the pushing action of the ground wire pin; a first magnetic member 500 is provided in the ground wire protection door 330, and a second magnetic member 501 is provided in the live wire protection door 310; the live wire protection door 310 and the neutral wire protection door 320 are linked with the second magnetic member 501 through the first magnetic member 500; the live wire protection door 310 has a live wire avoidance portion 312 and an upwardly protruding live wire blocking portion 311; the live wire blocking portion 311 is used to embed into the live wire jack 111 under the action of the first magnetic member 500 and the second magnetic member 501 when the pin is not inserted into the jack; when the pin is inserted into the jack, the live wire pin passes through the live wire protection door 310 through the live wire avoidance portion 312.
[0036] In the present invention, the live wire protection door 310 and the ground wire protection door 330 are linked by the magnetic attraction between the first magnetic part 500 and the second magnetic part 501. The ground wire protection door 330 has a pushing slope. When the ground wire pin is inserted into the ground wire jack 113, the ground wire pin pushes the ground wire protection door 330 to slide. The first magnetic part 500 is fixed to the ground wire protection door 330 and moves with the ground wire protection door 330, and attracts the second magnetic part 501 to slide with the first magnetic part 500 on the other side of the first longitudinal partition 210, thereby driving the live wire protection door 310 to slide and open the live wire jack 111. Before the plug is inserted into the socket, the live wire blocking portion 311 on the live wire protection door 310 is embedded in the live wire socket 111. If the live wire pin is not inserted into the live wire socket 111, when the ground wire pin is inserted into the ground wire socket 113 and pushes the ground wire protection door 330 to move, the live wire protection door 310 will be stuck in the live wire socket 111 due to the live wire blocking portion 311, resulting in the live wire protection door 310 being unable to open; and if the live wire pin is inserted but the ground wire pin is not inserted, the live wire protection door 310 sinks and the live wire blocking portion 311 is disengaged from the live wire socket 111. However, because the live wire protection door 310 itself has no pushing surface, the live wire pin cannot push the live wire protection door 310 after contacting it, and the ground wire protection door 330 cannot be pushed to open normally if the ground wire pin is not correctly inserted. Therefore, the present invention can reduce the possibility of accidental electric shock caused by the insertion of foreign objects or non-standard plugs, which could cause the live wire protection door 310 to open. In the present invention, the plug can only push the protection door assembly 300 via the push slope on the ground wire protection door 330. Before the live wire plug is inserted, the live wire blocking portion 311 of the live wire protection door 310 is locked in the live wire jack 111. Therefore, a standard plug must be used to open the protection door assembly 300, ensuring the safety of the socket.
[0037] In the present invention, the first longitudinal partition 210 separates the live wire protection door 310 and the ground wire protection door 330, and the live wire pin and the ground wire pin of the plug are also separated accordingly. After the socket housing 100 is accidentally flooded with water, the live wire pin and the ground wire pin cannot be connected by the water entering the housing 100, thereby preventing a short circuit after water ingress.
[0038] The protective door assembly 300 has a protective state and an open state. When the pin is inserted into the socket, the protective door assembly 300 is in the open state; when the pin is pulled out of the socket, the protective door assembly 300 returns to the protective state; when the protective door assembly 300 is in the open state, the second magnetic member 501 is lower than the first magnetic member 500, and the top of the live wire blocking portion 311 abuts the inner surface of the face shell 110; when the pin is pulled out of the socket and the protective door assembly 300 returns from the open state to the protective state, the ground wire protective door 330 is reset under the action of the reset mechanism, driving the live wire protective door 310 to reset. After the live wire protective door 310 is reset, the second magnetic member 501 is lifted upward under the action of the first magnetic member 500, and drives the live wire blocking portion 311 to embed into the live wire socket 111.
[0039] The present invention also proposes an embodiment, in which the protective door assembly 300 further includes a neutral wire protective door 320, which has a neutral wire avoidance portion 322 and an upwardly protruding neutral wire hole blocking portion 321; the neutral wire hole blocking portion 321 is used to rise upward under the action of the first magnetic member 500 and the third magnetic member 502 when the pin is not inserted into the jack, and embed into the neutral wire jack. The neutral wire protective door 320 is provided with a third magnetic member 502, and the neutral wire protective door 320 and the ground wire protective door 330 are linked to the first magnetic member 500 through the third magnetic member 502; a second longitudinal partition 211 is provided above the protective partition 200, and the ground wire protective door 330 and the neutral wire protective door 320 are respectively located on either side of the second longitudinal partition 211. When the protective door assembly 300 is in the open state, the third magnetic part 502 is lower than the first magnetic part 500, and the top of the neutral wire blocking portion 321 abuts the inner surface of the face shell 110; when the protective door assembly 300 is restored from the open state to the protective state, the ground wire protection door 330 is reset under the action of the reset mechanism, driving the neutral wire protection door 320 to reset, and the third magnetic part 502 is lifted upward under the action of the first magnetic part 500, and drives the neutral wire blocking portion 321 to embed into the neutral wire jack 112.
[0040] A boss is further provided on the side of the live wire blocking portion 311 to prevent the blocking portion from extending upward from the live wire jack 111 .
[0041] In order to facilitate the installation of the protective partition 200, the present invention proposes an embodiment, in which the safety socket includes a socket unit, and the socket unit includes the protective partition 200, the protective door assembly 300 and the plug-in compartment 400; a plug-in component is arranged in the plug-in compartment 400, and the protective partition 200 is located above the plug-in compartment 400.
[0042] The plug-in compartment 400 includes a live plug-in compartment 401, a neutral plug-in compartment 402, and a ground plug-in compartment 403, all isolated from each other. The protective partition 200 covers the plug-in compartment 400, and a sealing mechanism is provided between the protective partition 200 and the live plug-in compartment 401, the neutral plug-in compartment 402, and the ground plug-in compartment 403. The sealing mechanism includes a sealing strip or a sealing rubber ring disposed between the openings of each plug-in compartment and the partition. The sealing mechanism can also be configured by providing a groove 233 on the lower surface of the partition that matches the shape of each plug-in compartment opening, with the top end of each plug-in compartment embedded in the groove 233.
[0043] The protective baffle 200 also includes upwardly extending side panels 220 to form protective cavities. These cavities include a live wire protective cavity 230, a neutral wire protective cavity 231, and a ground wire protective cavity 232. The live wire protective door 310 is located in the live wire protective cavity 230, the neutral wire protective door 320 is located in the neutral wire protective cavity 231, and the ground wire protective door 330 is located in the ground wire protective cavity 232. The upper openings of each protective cavity are sealed to the inner surface of the housing 110, and the lower surface of the baffle is sealed to the various plug-in compartments, preventing water from entering one plug-in socket and flowing into other protective cavities and other plug-in compartments.
[0044] The protective partition 200 covers and seals the isolated plug compartments. After the pins are inserted into the sockets to connect to the live connectors, if water enters from the gap between the pins and the sockets, the water cannot flow into the different protective cavities or plug compartments after entering the shell. This can more effectively prevent the live wire and the neutral wire or the ground wire from being short-circuited by the entering water, thereby improving the waterproof performance of the safety socket.
[0045] In the implementation of the safety socket adopting a unit-type structure, multiple socket units can be set in one safety socket to be implemented as a power strip; or only one socket unit can be set to be implemented as a wall plug, etc.
[0046] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
