Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a protective door assembly for a safety socket and a safety socket. Background Technology

[0002] The safety of power sockets has always been one of the most important performance characteristics, with numerous electric shock accidents caused by children accidentally touching the live wire connection every year. Improving socket safety has consistently been a key research focus for engineers. Currently, one solution to enhance safety is to install a protective door structure on the socket panel. When the socket is not in use, the protective door closes the socket's opening, preventing conductive objects from accidentally contacting the metal contacts inside. When a plug is inserted, the prongs first push open the protective door to open the opening before continuing to insert into the socket and making contact with the metal contacts to achieve conductivity. However, safety sockets using protective doors require a linkage mechanism that moves the neutral and live wire protective doors simultaneously. Current protective door mechanisms typically integrate the live and neutral wire protective doors or use linkages, which inevitably means that the neutral and live wire prongs are not isolated at the protective door. If water enters the socket, this can cause the neutral and live wire prongs to conduct, resulting in a short circuit. Summary of the Invention

[0003] The main objective of this invention is to provide a protective door assembly for a safety socket and a safety socket, aiming to solve the problem that existing safety socket protective doors cannot prevent short circuits between the live wire and neutral wire pins when water enters the socket.

[0039] This invention proposes a protective door assembly for a safety socket and a safety socket using the protective door assembly. Figures 1 to 12 This is a first embodiment of the protective door assembly for a safety socket proposed in this invention, wherein the protective door assembly of this embodiment is a two-hole protective door mechanism; Figures 13 to 19This is a second embodiment of the protective door assembly for the safety socket proposed in this invention. The protective door assembly in this embodiment is a three-hole protective door mechanism.

[0040] Please refer to Figures 1 to 12 The safety socket protective door assembly proposed in this invention is an embodiment of a two-hole protective door mechanism. In this embodiment, the safety socket protective door assembly includes a panel 100, a bottom shell 200, a neutral wire protective door 400, a live wire protective door 500, and a magnetic component 300. The panel 100 has a first neutral wire socket 101 and a first live wire socket 102. The bottom shell 200 has a second neutral wire socket 207 opposite to the first neutral wire socket 101 and a second live wire socket 208 opposite to the first live wire socket 102. A partition 203 is provided on the bottom shell 200. The panel 100 and the bottom shell 200... The shell 200 encloses a protective cavity, and the partition 203 divides the protective cavity into a neutral wire protection cavity 210 and a live wire protection cavity 211. The neutral wire protection door 400 is disposed in the neutral wire protection cavity 210, and the live wire protection door 500 is disposed in the live wire protection cavity 211. The magnetic suction assembly 300 includes a first magnetic suction member 301 and a second magnetic suction member 302. The first magnetic suction member 301 is fixed to the neutral wire protection door 400, and the second magnetic suction member 302 is fixed to the live wire protection door 500. The neutral wire protection door 400 and the live wire protection door 500 are linked together by the magnetic suction assembly 300.

[0041] A two-hole protective door mechanism is installed at the two-hole socket of the safety socket to replace the panel with the socket of a traditional socket. In this embodiment, the two-hole protective door mechanism uses a partition 203 to isolate the protective cavity formed by the panel 100 and the bottom shell 200 into a neutral wire protective cavity 210 and a live wire protective cavity 211. The neutral wire protective door 400 is installed in the neutral wire protective cavity 210 to close the channel between the first neutral wire socket 101 and the second neutral wire socket 207. When the neutral wire plug is inserted into the first neutral wire socket 101, the neutral wire protective door 400 needs to be opened first to allow the first neutral wire socket 101 and the second neutral wire socket 207 to pass through, so that the neutral wire plug can be inserted into the second neutral wire socket 207 and enter the socket. Similarly, the live wire protection door 500 is installed inside the live wire protection cavity 211 to close the channel between the first live wire socket 102 and the second live wire socket 208. When the live wire pin is inserted into the first live wire socket 102, the live wire protection door 500 needs to be opened first to make the first live wire socket 102 and the second live wire socket 208 connected, so that the live wire pin can be inserted into the second live wire socket 208 and enter the socket.

[0042] The partition 203 is integrally formed with the bottom shell 200, which also includes a bottom plate 202 and a side plate 201. The key function of the partition 203 is to isolate the protective cavity into a neutral wire protective cavity 210 and a live wire protective cavity 211. When conductive liquid accidentally enters the neutral wire protective cavity 210 or the live wire protective cavity 211, the conductive liquid will not conduct electricity between the neutral wire pin and the live wire pin due to the isolation effect of the partition 203.

[0043] The introduction of partition 203 inevitably prevents the neutral wire protection door 400 and the live wire protection door 500 from being structurally connected, and the linkage between the two protection doors increases the difficulty of inserting non-standard parts into the socket. Therefore, in order to maintain the linkage between the neutral wire protection door 400 and the live wire protection door 500 while adding partition 203, this embodiment uses magnetic attraction components 300 on the neutral wire protection door 400 and the live wire protection door 500 to achieve magnetic linkage. In this embodiment, the linkage between the neutral wire protection door 400 and the live wire protection door 500 is achieved by the mutual attraction between the first magnetic attraction component 301 fixed on the neutral wire protection door 400 and the second magnetic attraction component 302 fixed on the live wire protection door 500. The first magnetic attraction component 301 can be integrally formed with the neutral wire protection door 400, or a groove 401 can be opened on the side of the neutral wire protection door 400 near partition 203 to fix the first magnetic attraction component 301 in the groove 401.

[0044] To further enhance the safety of the protective door assembly and prevent non-standard plugs from pushing open the neutral wire protective door 400 and the live wire protective door 500, the neutral wire protective door 400 in this embodiment has a first driving part 402 and the live wire protective door 500 has a second driving part 501. The first driving part 402 and the second driving part 501 are staggered and spaced apart in the moving direction of the neutral wire protective door 400, and the height of the second driving part 501 is lower than that of the first driving part 402.

[0045] After the neutral wire plug is inserted into the first neutral wire socket 101, it pushes the neutral wire protection door 400 to slide. The live wire protection door 500 slides together with the neutral wire protection door 400 under the action of the magnetic component 300. At this time, the live wire plug has not yet contacted the live wire protection door 500. The distance the neutral wire plug pushes the first drive unit 402 to move is the first stroke. After the neutral wire protection door 400 and the live wire protection door 500 move together for the first stroke, the second drive unit 501 on the live wire protection door 500 moves to the live wire plug. The live wire plug begins to push the second drive unit 501, causing the live wire protection door 500 to slide. At this time, the neutral wire plug disengages from the neutral wire protection door 400, and the neutral wire protection door 400 slides together with the live wire protection door 500 under the action of the magnetic component 300. The distance the live wire prong pushes the live wire protection door 500 to move is the second stroke. After the live wire protection door 500 moves the neutral wire protection door 400 together with the magnetic component 300 for the second stroke, both the neutral wire protection door 400 and the live wire protection door 500 are fully opened. The neutral wire prong and the live wire prong of the plug can pass through the protection door assembly from the first neutral wire socket 101, the second neutral wire socket 207 and the first live wire socket 102, the second live wire socket 208 respectively, and be inserted into the socket. That is, the process of inserting the plug into the socket is as follows: the neutral wire prong pushes the first driving part 402 (first stroke begins) → the neutral wire protection door 400 drives the live wire protection door 500 to slide → the second driving part 501 moves to the live wire prong (first stroke ends) → the live wire prong pushes the second driving part 501 (second stroke begins) → the live wire protection door 500 drives the neutral wire sliding door to slide → the protection door assembly is fully opened (second stroke ends) → the plug prong is inserted into the socket → the power is turned on.

[0046] In this embodiment, springs are also provided in the neutral wire protection cavity 210 and the live wire protection cavity 211 so that the neutral wire protection door 400 and the live wire protection door 500 are reset after the plug pins are pulled out.

[0047] Please refer to Figures 13 to 19The safety socket protective door assembly proposed in this invention is an embodiment of a three-hole protective door mechanism. In this embodiment, the safety socket protective door assembly includes a panel 100, a bottom shell 200, a neutral wire protective door 400, a live wire protective door 500, and a magnetic component 300. The panel 100 has a first neutral wire socket 101 and a first live wire socket 102. The bottom shell 200 has a second neutral wire socket 207 opposite to the first neutral wire socket 101 and a second live wire socket 208 opposite to the first live wire socket 102. A partition 203 is provided inside the bottom shell 200. The panel 100 and the bottom shell 200... The shell 200 encloses a protective cavity, and the partition 203 divides the protective cavity into a neutral wire protection cavity 210 and a live wire protection cavity 211. The neutral wire protection door 400 is disposed in the neutral wire protection cavity 210, and the live wire protection door 500 is disposed in the live wire protection cavity 211. The magnetic suction assembly 300 includes a first magnetic suction member 301 and a second magnetic suction member 302. The first magnetic suction member 301 is fixed to the neutral wire protection door 400, and the second magnetic suction member 302 is fixed to the live wire protection door 500. The neutral wire protection door 400 and the live wire protection door 500 are linked together by the magnetic suction assembly 300.

[0048] The partition 203 is integrally formed with the bottom shell 200. Its key function is to separate the neutral wire protection cavity 210 and the live wire protection cavity 211. When conductive liquid accidentally enters the neutral wire protection cavity 210 or the live wire protection cavity 211, the conductive liquid will not conduct electricity between the neutral wire pin and the live wire pin due to the isolation effect of the partition 203.

[0049] The introduction of partition 203 inevitably prevents the neutral wire protection door 400 and the live wire protection door 500 from being structurally connected. Therefore, in order to maintain the linkage between the neutral wire protection door 400 and the live wire protection door 500 while adding partition 203, this embodiment adopts a method of setting magnetic suction components 300 on the neutral wire protection door 400 and the live wire protection door 500 to achieve magnetic linkage. The first magnetic suction component 301 can be integrally formed with the neutral wire protection door 400, or a groove 401 can be opened on the side of the neutral wire protection door 400 near partition 203 to fix the first magnetic suction component 301 in the groove 401.

[0050] The three-hole protective door assembly is installed at the three-hole socket of the safety socket to replace the panel with the socket of the traditional socket. In this embodiment, the three-hole protective door mechanism is provided with a partition 203 to divide the protective cavity into a neutral wire protective cavity 210 and a live wire protective cavity 211. In this embodiment, in addition to all the functions listed in the previous embodiment, the partition 203 also has the function of forming a ground wire protective cavity 212.

[0051] Specifically, in this embodiment, the panel 100 is provided with a first grounding socket 103, and the bottom shell 200 is provided with a second grounding socket 209 corresponding to the first grounding socket 103. The safety socket's protective door assembly also includes a grounding protective door 600 and a third magnetic member 303. The third magnetic member 303 is fixed to the grounding protective door 600 and is linked with the first magnetic member 301 and the second magnetic member 302. The partition 203 includes a first partition 204 and a second partition 205, and the grounding protective door 600 is disposed between the first partition 204 and the second partition 205.

[0052] The space between the first partition 204 and the second partition 205 is a ground wire protection cavity 212, and the ground wire protection door 600 is disposed in the ground wire protection cavity 212 and can slide in the ground wire protection cavity 212.

[0053] The third magnetic attractor 303 attracts the first magnetic attractor 301 and the second magnetic attractor 302 respectively, so that the ground wire protection door 600, the neutral wire protection door 400 and the live wire protection door 500 are linked together. In this embodiment, the ground wire protection door 600 has a third driving part 601, and the third driving part 601 has a third inclined surface 602. After the ground wire pin of the plug is inserted into the first ground wire socket 103, it abuts against the third inclined surface 602 and squeezes the third driving part 601. Under the action of the ground wire pin, the ground wire protection door 600 slides together with the neutral wire protection door 400 and the live wire protection door 500 through the magnetic attractor 300, so as to open the ground wire protection door 600, the neutral wire protection door 400 and the live wire protection door 500, so that the ground wire pin, the neutral wire pin and the live wire pin can pass through the second ground wire socket 209, the second neutral wire socket 207 and the second live wire socket 208 respectively and enter the socket.

[0054] In this embodiment, the ground wire protection door 600 is provided with a through hole 603, and the third magnetic suction member 303 is fixed in the through hole 603. This embodiment also provides a limiting member 206 between the first partition 204 and the second partition 205 for limiting the ground wire protection door 600. This embodiment also provides a spring in the ground wire protection cavity 212 so that the ground wire protection door 600 resets after the plug pins are pulled out.

[0055] The safety socket proposed in this invention includes at least one of the two embodiments described above. That is, the safety socket proposed in this invention can be a two-hole safety socket, a three-hole safety socket, or a safety socket that combines two-hole and three-hole insertion compartments.
