The bottom shell 12 is provided with a plurality of drainage holes 120 that are connected inside and out. The inner liner 2 is provided with two chambers arranged side by side. In the two chambers, a first partition plate 21 and a second partition plate 22 that can be elastically reset are respectively provided. The first partition plate 21 divides its chamber into a first main chamber 201 and a first secondary chamber 202, while the second partition plate 22 divides its chamber into a second main chamber 203 and a second secondary chamber 204.

[0026] See appendix Figures 8 to 11The neutral wire assembly 3 includes a neutral wire connector 31, a neutral wire external connector 32, and a neutral wire adapter 33. The neutral wire connector 31 includes a set of neutral wire connector pieces 311 that bend upwards from the base and converge towards each other, forming a neutral wire interface 310 between the neutral wire connector pieces 311. A set of resiliently reset neutral wire movable contacts 312 is provided on the side of the neutral wire interface 310. The neutral wire movable contacts 312 are configured to expand outwards when the pin is inserted into the neutral wire interface 310 and reset when the pin is withdrawn from the neutral wire interface 310.

[0027] See appendix Figure 8 , 9 12, the live wire assembly 4 includes a live wire connector 41, a live wire external connector 42, and a live wire adapter 43. The live wire connector 41 includes a set of live wire connector pieces 411 that bend upwards from the base and converge towards each other, forming a live wire interface 410 between the live wire connector pieces 411. A set of elastically resettable live wire movable contacts 412 is provided on the side of the live wire interface 410. The live wire movable contacts 412 are configured to expand outwards when the pin is inserted into the live wire interface 410 and reset when the pin is withdrawn from the live wire interface 410.

[0028] See appendix Figure 3 The neutral wire connector 31 is disposed in the first main chamber 201 with its neutral wire movable contact 312-A facing the first partition plate 21. One end of the neutral wire adapter 33 is disposed in the first main chamber 201 and faces the neutral wire movable contact 312-B on the other side of the neutral wire connector 31. The other end of the neutral wire adapter 33 is disposed in the second auxiliary chamber 204 and is in close contact with the second partition plate 22. The live wire connector 41 is disposed in the second main chamber 203 with its live wire movable contact 412-A facing the second partition plate 22. One end of the live wire adapter 43 is disposed in the second main chamber 203 and faces the live wire connector 41 on the other side of the live wire connector 41. The live wire contact 412-B is directly opposite to the live wire adapter 43, which is located in the first sub-chamber 202 and is in close contact with the first partition plate 21. The neutral wire external connector 32 is located in the first sub-chamber 202, with one end directly opposite to one end of the live wire adapter 43 located in the first sub-chamber 202, and the other end protruding from the inner liner 2 for connecting the neutral wire. The live wire external connector 42 is located in the second sub-chamber 204, with one end directly opposite to one end of the neutral wire adapter 33 located in the second sub-chamber 204, and the other end protruding from the inner liner 2 for connecting the live wire. The ground wire assembly 5 is housed in the third chamber 205 of the inner liner 2.

[0029] See appendix Figures 4 to 7The bottom of the inner liner 2 is provided with a first groove 205 for connecting the first main chamber 201 and the second auxiliary chamber 204, and a second groove 206 for connecting the first auxiliary chamber 202 and the second main chamber 203. The first groove 205 is arranged along the bottom surface of the inner liner 2 (see attached diagram). Figure 5 (The area indicated by the slashed bar) The second groove 206 is arranged along a vertical plane perpendicular to the bottom surface of the inner liner 2 (see Appendix). Figure 6 (The area shown by the dotted shadow) The bottom surface of the inner liner 2 is provided with several limiting posts 23. The neutral wire adapter 33 and the live wire adapter 43 are respectively provided with through holes adapted to the limiting posts 23. The shape of the neutral wire adapter 33 is adapted to the first wire groove 205, and the shape of the live wire adapter 43 is adapted to the second wire groove 206. By using two wire grooves arranged in different dimensions, physical separation is achieved when the neutral wire adapter 33 and the live wire adapter 43 are running, so there is no need to consider the insulation treatment at the intersection of the two wires.

[0030] To ensure effective contact and reduce travel distance, raised electrical contacts 6 are provided on each electrical contact portion of the neutral wire moving contact 312, neutral wire external connector 32, neutral wire adapter 33, live wire moving contact 412, live wire external connector 42, and live wire adapter 43.

[0031] The working principle of this utility model is as follows: When the plug is inserted into the neutral wire connector 310, the neutral wire moving contacts 312 on both sides of the neutral wire connector 310 are forced to expand outward under the squeezing action of the plug. After the plug is fully inserted into the neutral wire connector 310, the neutral wire moving contact 312-A will press against the first partition plate 21, and then press one end of the live wire adapter 43 that is in close contact with it against one end of the live wire external connector 42 in the same first secondary chamber 202. The neutral wire moving contact 312-B will press against the neutral wire external connector 32 in the same first main chamber 201. One end contacts; similarly, when the pin is inserted into the live wire connector 410, the live wire moving contacts 412 on both sides of the live wire connector 410 are forced to expand outward under the squeezing action of the pin. When the pin is fully inserted into the live wire connector 410, the live wire moving contact 412-A will press against the second partition plate 22, and then press one end of the neutral wire adapter 33 that is in close contact with it against one end of the neutral wire external connector 32 in the same second auxiliary chamber 204. The live wire moving contact 412-B will contact one end of the live wire external connector 42 in the same second main chamber 203.

[0032] It is evident that the neutral wire assembly 3 and the live wire assembly 4 can only be energized when both the neutral and live wires are inserted simultaneously. When only the neutral wire is inserted, although one end of the neutral wire adapter 33 is connected to the neutral wire connector 31, the other end is not connected to the neutral wire external connector 32. Similarly, although one end of the live wire adapter 43 is connected to the live wire external connector 43 to complete the energization, the other end is not connected to the live wire connector 41. Therefore, neither the neutral wire connector 31 nor the live wire connector 41 is energized. Likewise, when only the live wire is inserted, although one end of the live wire adapter 43 is connected to the live wire connector 41, the other end is not connected to the live wire external connector 42. Similarly, although one end of the neutral wire adapter 33 is connected to the neutral wire external connector 33 to connect the neutral wire, the other end is not connected to the neutral wire connector 41. Therefore, neither the neutral wire connector 31 nor the live wire connector 41 is energized.

[0033] This invention achieves cross-connection control of the neutral wire assembly 3 and the live wire assembly 4 through the cooperation of various plugs, external connectors and adapters in the neutral wire assembly 3 and the live wire assembly 4. Power is only connected when both the neutral and live wire sockets are plugged in. Power cannot be connected if only a conductor is plugged into a single live wire socket or neutral wire socket, thus giving the socket an excellent anti-electric shock mechanism.

[0034] Furthermore, the neutral wire connector 31 and the live wire connector 41 have the following implementation structures:

[0035] See appendix Figure 10 , 11 13. The neutral wire connector 31 includes a base 313 and a neutral wire movable contact 312 detachable from the base 313. Neutral wire connector pieces 311 are bent upwards and extended from both sides of the base 313 and then converged towards each other. Connecting holes 3130 are provided at both ends of the base 313. The neutral wire movable contact 312 is formed by bending a strip of copper sheet, with the bent portion 3121 of the strip of copper sheet as the bottom end, and a connector 3122 is provided at the bottom end. The connector 3122 is inserted into the connecting hole 3130 to form a fulcrum, so that the strip of copper sheet... The upper part can be flipped around the fulcrum. A curved part 3124 that protrudes inward (neutral wire connector 310) is provided on the inner section 3123 of the strip copper sheet. The upper end of the inner section 3123 extends outward. A torsion spring 314 acts on the concave surface of the curved part 3124 to make the two neutral wire moving contacts 312 close towards each other under the action of elastic force. Specifically, the torsion body 3141 of the torsion spring 314 is provided on the base 313, and its spring feet 3142 respectively abut against the concave surface of the curved part 3124 of the two neutral wire moving contacts 312.

[0036] This achieves the following: when the pin is inserted into the neutral wire connector 310, it expands outward and returns to its original position when the pin is withdrawn from the neutral wire connector 310. The structure of the live wire connector 41 is the same as that of the neutral wire connector 31 described above. Here, only the structure of the neutral wire connector 31 is used as an example, and will not be described again.

[0037] As an optimized structure, see Appendix Figure 14 and 15 The torsion spring 314 has a spring-shaped torsion body 3141. This spring-shaped torsion body 3141 not only provides sufficient torque but also has better recovery performance than traditional torsion springs (which use only a crossbar as the torsion body) and is less prone to metal damage, resulting in a longer service life. In addition, any elastic structure that can provide a restoring force for the moving contact body falls within the scope of this patent.

[0038] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
