The other end of the column 47 is sealed and connected with the other side corresponding to the second cavity 37 through the sealing ring 48. The other side corresponding to the second cavity 37 is provided with a drainage outlet 49 connected with the interior of the second column 47.

[0035] like Figure 5 and Figure 8 As shown, an annular sealing groove 50 is provided on the edge of the seat body 35, and notches 51 corresponding to the corresponding wiring areas 43 are respectively provided on the inner side walls at both ends of the sealing groove 50, and a waterproof ring 52 is provided in the sealing groove 50, and two sealing blocks 53 are integrally formed on the waterproof ring 52, and the two sealing blocks 53 are symmetrically distributed on the left and right and respectively correspond to the notches 51 at both ends of the sealing groove 50. Limiting plates 54 that fit the two sealing blocks 53 one by one are fixed on the outer side walls at both ends of the sealing groove 50, respectively, and the edge of the bottom cover 36 matches the sealing groove 502 and is sealed with the sealing groove 50 through the waterproof ring 52. U-shaped grooves 55 are provided at both ends of the bottom cover 36, and the wiring port 46 is composed of the corresponding U-shaped groove 55 and the corresponding limiting plate 54. A silicone pressure block 56 that matches the corresponding sealing block 53 is detachably connected in the U-shaped groove 55.

[0036] Embodiment 1: The sealing silicone strip 10 protruding from the silicone sheet 2 helps to squeeze the sealing silicone strip 10 to seal the gap between the plug and the socket body 1 after the plug is inserted into the socket 3 on the socket body 1, preventing water from penetrating from the surface into the socket body 1, thereby achieving the purpose of reducing the risk of water ingress during the use of the socket and improving the safety of use. Regardless of whether the plug is plugged into the three-pin socket 4 or the two-pin socket 8, the protective effect of the sealing silicone strip 10 with a multi-layer design further improves the waterproof effect of the socket when it is in use.

[0037] The diameter of the connecting hole 2 30 corresponding to the live wire jack 5 and the neutral wire jack 6 on the silicone sheet 2 29 is smaller than the diameter of the jack 3, so that the connecting hole 2 30 can be interference fit with the pin on the plug, thereby achieving the purpose of waterproofing again on the basis of the silicone sheet 1 2. The retaining ring 31 provided on the silicone sheet 29 is beneficial to prevent water from entering from the side of the socket body 1, further comprehensively improving the waterproof effect of the socket when it is used.

[0038] The upper cover 23 is sealed with the base 11 through the waterproof ring 1 33 to prevent water from leaking from the outside of the socket body 1 into the socket body 1; the waterproof ring 2 52 and the sealing block 53 are preferably made of silicone in one piece; the seat body 35 and the bottom cover 36 are waterproofly sealed by the waterproof ring 2 52. At the same time, when the power cord is connected from the wiring port 46, the sealing block 53 and the silicone pressing block 56 on the waterproof ring 2 52 are respectively located on the left and right sides of the power cord and are interference fit with the power cord so that the circumference of the power cord is tightly wrapped. Through this silicone hard extrusion method, a better waterproof sealing effect is obtained when the wiring port 46 is connected.

[0039] Since the ground wire area does not need to be waterproof, the tube body 34 and the column 47 are sealed and connected to the cavity 2 37 through the sealing ring 48, so that the ground wire area is isolated from the live wire area and the neutral wire area respectively, which is beneficial to prevent water from entering the live wire area and the neutral wire area. Therefore, the design of the drain port 49 is convenient for leaking water to the ground wire.

[0040] In the initial state, the safety door 15 completely covers the corresponding live wire jack 5 and neutral wire jack 6 under the action of the spring 21; the design of the safety door 15 makes the live wire jack 5 and neutral wire jack 6 on the three-pin jack 4 and the two-pin jack 8 covered with a two-layer structure of baffle 1 18 and baffle 2 19. When a single needle is inserted into any one of the jacks 3, even if baffle 18 is pushed open, the single needle cannot be inserted into the corresponding electrical socket 14 due to the protection of baffle 2 19. Therefore, the structure can only be fully opened when pins are inserted into the live wire jack 5 and the neutral wire jack 6 at the same time. Compared with the traditional structure, it is beneficial to further improve the safety performance.

[0041] In summary, the waterproof sealing performance and the safety performance of the utility model are comprehensively improved through the above structure.

[0042] Embodiment 2: During installation, first fix the silicone sheet 2 in the groove 25 on the panel 24 by gluing or other methods; then insert the silicone sheet 29 into the corresponding connection hole 27 through the skirt 32, and embed the silicone sheet 29 into the groove 26, and finally position the silicone sheet 29 by snapping the panel 24 and the upper cover 23, thereby completing the assembly of the cover body 12; then install the waterproof ring 33 and the safety door 15, and install and match the upper cover 23 with one side of the seat body 35 on the base 11 by bolting or other methods; the operator connects the live wire metal parts 38, the parts 38 and the parts 38 through the other side of the seat body 35. The wire metal piece 39 and the ground wire metal piece 40 are installed at the corresponding positions, and then the waterproof ring 2 52 is installed in the sealing groove 50; the power cord is riveted to the corresponding wiring area 43, and the power cord is fitted with the corresponding sealing block 53; finally, the silicone pressure block 56 is installed in the corresponding U-shaped groove, and the bottom cover 36 with the silicone pressure block 56 installed is installed and matched with the other side corresponding to the base 11 by bolt connection. At this time, the sealing block 53 and the silicone pressure block 56 on the waterproof ring 2 52 are respectively located on the left and right sides of the power cord and are interference fit with the power cord so that the circumference of the power cord is tightly wrapped; finally, the ground wire can be welded.
