[0036] Currently, most socket products on the market do not have waterproof functions and are mainly suitable for dry indoor environments. If used in a humid environment, moisture can easily penetrate the conductive components inside the socket, causing safety hazards such as short circuits and leakage.

[0037] To improve waterproofing, some sockets are now equipped with waterproof covers. However, the gap between the waterproof cover and the socket still poses a risk of water ingress, potentially leading to the aforementioned safety issues. Furthermore, with the development of new energy vehicle technology, the external discharge function of these vehicles is becoming increasingly common, leading to a wider range of applications for vehicle discharge sockets. These sockets are typically exposed to humid environments such as rain, car wash water, and splashing water. External water can easily seep into the socket through the gap between the waterproof cover and the socket, coming into contact with internal conductive components and posing safety hazards such as short circuits and electrical leakage.

[0038] Based on the above problems, this application proposes a waterproof socket. By setting up multiple steps, it can block, seal and intercept water that enters through the gap between the waterproof cover and the socket, thus constructing a multi-level water storage and step-by-step water blocking waterproof structure. This can prevent external water from directly intruding into the working platform where conductive components are installed, thereby improving the waterproof performance and electrical safety of the socket in humid environments.

[0039] It should be noted that the waterproof socket provided in this application can be applied to the vehicle discharge socket of new energy vehicles. Specifically, the waterproof socket can serve as an external discharge socket for new energy vehicles, allowing external electrical equipment to connect and draw power. Due to the complex operating environment of vehicles, the vehicle discharge socket may be affected by external water bodies such as rainwater and car wash water. By adopting the multi-stage water storage and progressive water blocking waterproof structure provided in this application, external water bodies can be prevented from intruding into the working platform and conductive components, which is beneficial to improving the electrical safety of the vehicle discharge socket. In addition, the waterproof socket provided in this application can also be applied to other electrical sockets that require waterproofing and / or dustproofing, and this application does not limit this application.

[0040] Please see Figures 1 to 3 An embodiment of this application provides a waterproof socket, comprising: The socket body 1 has a first platform 1011, a second platform 1012 and a working platform 1013 arranged from the outside to the inside on its top. The second platform 1012 is higher than the first platform 1011 and the working platform 1013 is higher than the second platform 1012. The working platform 1013 is provided with a socket hole 10131 for plug 12 to be inserted. Cover 2 is movably fitted onto the top of socket body 1, covering the first platform 1011, the second platform 1012 and the working platform 1013; the first mating gap 3 between the edge of cover 2 and socket body 1 is set toward the first platform 1011.

[0041] In this embodiment, the first platform 1011, the second platform 1012, and the working platform 1013 are arranged sequentially from the outside to the inside on the top of the socket body 1; where "from the outside to the inside" refers to the direction from the edge side of the socket body 1 towards the center side on the horizontal projection plane; the first platform 1011 is located at the edge of the socket body 1, the second platform 1012 is located inside the first platform 1011, and the working platform 1013 is located inside the second platform 1012. The height of the first platform 1011, the second platform 1012, and the working platform 1013 increases progressively, with the drop between the first platform 1011 and the second platform 1012 forming a first-level step, and the drop between the second platform 1012 and the working platform 1013 forming a second-level step.

[0042] The work platform 1013 is provided with a socket 10131, the shape and size of which match the pins of the plug 12. A conductive component 13 is provided below the work platform 1013, the position of which corresponds to the socket 10131. When the plug 12 is inserted into the socket 10131, the ends of the pins can contact the conductive component 13, thereby achieving electrical conductivity.

[0043] The cover 2 can move relative to the socket body 1 to achieve two states: open and closed. Specific implementation methods include, but are not limited to, hinged, sliding connection, or detachable fastening. When the cover 2 is in the closed position, the cover 2 covers the first platform 1011, the second platform 1012, and the working platform 1013; that is, when the cover 2 is entirely placed on top of the socket body 1, the first platform 1011, the second platform 1012, and the working platform 1013 can be accommodated within the accommodating space formed between the cover 2 and the socket body 1.

[0044] A first fitting gap 3 is formed between the edge of the cover 2 and the socket body 1. This first fitting gap 3 is an unavoidable assembly or movement gap between the cover 2 and the socket body 1, used to ensure the normal opening and closing operation of the cover 2. The first fitting gap 3 is oriented towards the first platform 1011, meaning that water entering through the first fitting gap 3 can fall directly onto the first platform 1011 under gravity, without flowing across the first platform 1011 to the second platform 1012 or the working platform 1013. There are various specific structural methods for achieving the orientation of the first fitting gap 3 towards the first platform 1011; for example, the first fitting gap 3 can be set to extend horizontally or slope downwards from the outside inwards, ensuring that the water outlet end of the first fitting gap 3 facing inwards is flush with or above the first platform 1011; specifically as follows... Figure 1 As shown, when the cover 2 is in the closed state, the edge of the cover 2 can be directly pressed against the outer edge of the first platform 1011, thus ensuring that the first fitting gap 3 formed between the cover 2 and the first platform 1011 is flush with the first platform 1011. In practical applications, regardless of the specific structure used, the core is to ensure that the initial landing point of the water entering the containment space along the first fitting gap 3 points to the first platform 1011.

[0045] Based on the above structural configuration, when external water flow impacts the joint between the edge of the cover 2 and the socket body 1, some water enters the first mating gap 3. Since the first mating gap 3 faces the first platform 1011, the water entering the first mating gap 3 will spread along the first platform 1011. As the water volume increases, the water gradually enters the cavity formed by the first platform 1011 and the inner wall of the cover 2, causing the water level on the first platform 1011 to gradually rise until a water column is formed on the first platform 1011. At this time, the water accumulated on the first platform 1011 can physically block the water that subsequently enters along the first mating gap 3 based on its own surface tension and filling effect, thus buffering the subsequent water flow and reducing the transmission of water pressure, thereby forming a water seal effect. This water seal effect can be used to prevent water from continuing to enter the first platform 1011 and continue to accumulate on the first platform 1011.

[0046] When the water level on the first platform 1011 reaches a certain height, and under conditions of high external water pressure and large inflow, some water may bypass the first step formed between the first platform 1011 and the second platform 1012 and directly reach the second platform 1012. Since the second platform 1012 is higher than the first platform 1011, this part of the water needs to overcome gravitational potential energy to reach the second platform 1012. This process will consume the kinetic energy of the water and weaken its impact force. After the water reaches the second platform 1012, it will be blocked by the second step formed between the second platform 1012 and the working platform 1013 and will find it difficult to further enter the working platform 1013. The water that remains on the second platform 1012 can later flow back to the first platform 1011 under the action of gravity, thereby preventing the water from further seeping into the working platform 1013.

[0047] The work platform 1013 is an electrical work area, and water intrusion would pose a risk of short circuits and electrical leakage. This embodiment addresses this by incorporating two progressively higher steps, requiring external water to overcome gravity twice to reach the work platform 1013. Water trapped on the second platform 1012 can flow back to the first platform 1011 under gravity. Under IP55 waterproof rating testing conditions, external water pressure is typically insufficient to force water to continuously ascend the two steps and enter the work platform 1013, thus keeping the work platform 1013 continuously dry and improving the waterproof performance and electrical safety of the waterproof socket.

[0048] Therefore, the waterproof socket provided in this embodiment, by setting a first platform 1011, a second platform 1012, and a working platform 1013 with increasing height from the outside to the inside on the top of the socket body 1, and cooperating with a movable cover 2 covering the three platforms, with the first fitting gap 3 between the cover 2 and the socket body 1 facing the first platform 1011, allows external water to enter through the first fitting gap 3 and first accumulate on the first platform 1011 to form a water seal effect, preventing subsequent water from entering the first platform 1011. Some water reaching the second platform 1012 is intercepted and retained, and subsequently flows back to the first platform 1011 due to gravity. Based on the above structural configuration, a multi-stage water storage and progressive water blocking waterproof path is constructed, which can prevent external water from intruding into the working platform 1013, thereby improving the waterproof performance and electrical safety of the waterproof socket in humid environments. Therefore, the waterproof socket provided in this embodiment is particularly suitable for vehicle discharge sockets in new energy vehicles, and the above-mentioned multi-stage water storage and progressive water blocking waterproof path is beneficial to improving the electrical safety of vehicle discharge sockets.

[0049] In one embodiment, reference is made to Figure 4 and Figure 5 The cover 2 has a hinged side 201 and a movable side 202 that are disposed opposite to each other; the hinged side 201 is rotatably connected to the socket body 1, and the edge of the movable side 202 is provided with an accommodating notch 2021; When the cover 2 rotates downwards and closes onto the socket body 1, a receiving cavity 203 is formed between the cover 2 and the socket body 1. The receiving notch 2021 and the side wall of the socket body 1 form a wire passage 2022. The wire passage 2022 is connected to the receiving cavity 203 and is used to receive the power cord 1201 of the plug 12.

[0050] In this embodiment, as Figure 4 and Figure 5 As shown, the cover 2 can be configured as a box-shaped structure with an inner cavity. Two opposing sidewalls on the cover 2 form a hinge side 201 and a movable side 202, respectively. The hinge side 201 is rotatably connected to the socket body 1 via a pivot or hinge structure, allowing the cover 2 to rotate downwards relative to the socket body 1 around the hinge axis to achieve closing and upwards to achieve opening. During the closing process of the cover 2, the movable side 202 gradually approaches the corresponding sidewall of the socket body 1; during the opening process of the cover 2, the movable side 202 gradually moves away from the corresponding sidewall of the socket body 1. The edge of the movable side 202 has a recessed receiving notch 2021 extending towards the bottom wall of the cover 2. The receiving notch 2021 extends through the cover 2 along its thickness direction, and its shape can be semi-circular, U-shaped, rectangular, or other irregular shapes.

[0051] In practical applications, such as Figure 2As shown, with the cover 2 in the open state, the plug 12 can be inserted into the socket 10131 of the work platform 1013, and then the cover 2 can be rotated downwards to close the cover; during the closing process of the cover 2, the power cord 1201 of the plug 12 can gradually enter the bottom of the receiving notch 2021 from the opening of the receiving notch 2021; as Figure 1 and Figure 3 As shown, when the cover 2 is rotated downwards to completely cover the top of the socket body 1, the cover 2 is entirely covered above the socket body 1, and a closed or semi-closed space is formed between the inner cavity of the cover 2 and the socket body 1. This space is called the receiving cavity 203. The receiving cavity 203 is used to accommodate the plug 12 plugged into the work platform 1013 and the lead end of the power cord 1201. The movable side 202 is attached to the corresponding side wall of the socket body 1, and the receiving notch 2021 and the corresponding side wall of the socket body 1 enclose a wire passage 2022. One end of the wire passage 2022 is connected to the receiving cavity 203, and the other end is connected to the outside. The size and shape of the wire passage 2022 are configured to allow the power cord 1201 of the plug 12 to pass through, thereby realizing the lead-out of the power cord 1201 when the cover 2 is closed.

[0052] In one embodiment, the plug 12, which is inserted into the working platform 1013 and located within the receiving cavity 203, may include a power-receiving plug and a power-supplying plug; the power-receiving plug is used to obtain electrical energy from the waterproof socket, and the power-supplying plug is used to supply electrical energy to the waterproof socket. When the waterproof socket is applied to the vehicle discharge socket of a new energy vehicle, the plug 12 may be configured as a power-receiving plug, and the electrical energy of the new energy vehicle may be output to the power-receiving plug via the waterproof socket for use by external electrical equipment.

[0053] In one embodiment, reference is made to Figure 6 and Figure 7 The waterproof socket also includes a latch 4 and an elastic element 5; the latch 4 is movably fitted onto the socket body 1, and the two ends of the elastic element 5 are respectively connected to the latch 4 and the socket body 1. The latch 4 has a limiting boss 401 and a limiting groove 2023 on the movable side 202. When the latch 4 moves to the first position relative to the socket body 1, the limiting boss 401 extends to the outside of the socket body 1 and engages with the limiting groove 2023 to prevent the cover 2 from rotating upward and opening. When the latch 4 moves to the second position relative to the socket body 1, the limiting boss 401 retracts into the inside of the socket body 1 and separates from the limiting groove 2023. The elastic element 5 is used to keep the latch 4 in the first position under the elastic force.

[0054] In this embodiment, the limiting groove 2023 can be disposed on the side of the movable side 202 facing the socket body 1; the latch 4 can slide and engage with the bottom of the socket body 1 by means of a corresponding guide structure on the socket body 1, and the limiting protrusion 401 is disposed on the side of the latch 4 facing outward. Figure 6 As shown, when the cover 2 is in the closed state, the limiting protrusion 401 is opposite to the limiting groove 2023. In this case, based on the elastic force provided by the elastic element 5, the latch 4 can be driven to move outward in the direction close to the movable side 202, so that the latch 4 is kept in the first position. At this time, the limiting protrusion 401 extends out of the socket body 1 and engages with the limiting groove 2023. In this way, the engaging cooperation between the limiting protrusion 401 and the limiting groove 2023 can prevent the cover 2 from rotating upward and opening, thereby achieving the position locking of the cover 2 in the closed state, and preventing the cover 2 from opening on its own under the action of external factors, which would cause the protection of the plug 12 to fail.

[0055] like Figure 7 As shown, when it is necessary to open the cover 2, the latch 4 can be manually driven to overcome the elastic force of the elastic element 5 and move inward in the direction away from the movable side 202. When the latch 4 moves to the second position, the limiting boss 401 will retract into the interior of the socket body 1 and disengage from the limiting groove 2023, thus releasing the position lock of the cover 2, and the cover 2 can then be rotated upward to open. When the latch 4 is no longer subject to external driving force, the latch 4 can automatically reset to the first position under the elastic force provided by the elastic element 5, and the limiting boss 401 can continue to lock and limit the cover 2 in the closed state.

[0056] Among them, the elastic element 5 can be a spring, torsion spring, elastic colloid, etc., and there is no limitation here.

[0057] In one embodiment, reference is made to Figure 6 and Figure 7 The latch 4 has an operating part 402, which is exposed outside the socket body 1; when the operating part 402 is subjected to an external force, it drives the latch 4 to move from the first position to the second position.

[0058] Specifically, the operating part 402 can refer to a button, push rod, or other easily operable structure provided on the latch 4. By providing the operating part 402, the user can easily apply force to the operating part 402 by pressing or other means, thereby conveniently driving the latch 4 to move from the first position to the second position, so as to separate the limiting boss 401 from the limiting groove 2023, and then the cover 2 can be rotated upward to open.

[0059] In one embodiment, reference is made to Figure 6 and Figure 7The limiting boss 401 has a guide slope 4011, which is inclined downward along the direction in which the limiting boss 401 extends out of the socket body 1. During the process of the cover 2 rotating downward to close the cover, the movable side 202 abuts against the guide slope 4011 to drive the latch 4 to move from the first position to the second position.

[0060] like Figure 6 and Figure 7 As shown, when the latch 4 is in the first position, the limiting boss 401 extends out of the socket body 1, and the guide slope 4011 gradually slopes downward from the inside to the outside of the socket body 1. Based on this structure, when the cover 2 in the open state is rotated downward to close, the edge of the movable side 202 will first contact the guide slope 4011; as the cover 2 continues to rotate downward, the edge of the movable side 202 will slide relative to the guide slope 4011, thereby smoothly driving the limiting boss 401 to gradually retract inward, that is, driving the latch 4 to overcome the elastic force of the elastic element 5 and move inward to the second position as a whole; when the cover 2 is rotated to the closed state, the limiting groove 2023 of the movable side 202 is opposite to the limiting boss 401. At this time, the latch 4 will move outward again to the first position under the elastic force of the elastic element 5, so that the limiting boss 401 is engaged in the limiting groove 2023, thereby locking the position of the cover 2.

[0061] In this embodiment, by setting a guide slope 4011, the latch 4 can be moved synchronously during the closing operation of the cover 2, so that the limiting boss 401 can smoothly complete the repositioning operation as the cover 2 rotates, and can re-lock after the cover 2 is closed, thus eliminating the need to drive the latch 4 to reposition during the closing process and reducing the jamming problem during the movement of the cover 2 and the latch 4.

[0062] In one embodiment, reference is made to Figure 2 , Figure 4 and Figure 5 The waterproof socket also includes a first flexible waterproof material layer 6 and a second flexible waterproof material layer 7; the first flexible waterproof material layer 6 is disposed on the movable side 202, and the first flexible waterproof material layer 6 is at least partially located in the receiving notch 2021; the second flexible waterproof material layer 7 is disposed on the socket body 1; When the cover 2 is placed on the socket body 1, the first flexible waterproof material layer 6 and the second flexible waterproof material layer 7 are bonded together to seal the wire passage 2022.

[0063] Specifically, such as Figure 4 and Figure 5As shown, a mounting groove can be provided on the cover 2 near the movable side 202, and a mounting groove can also be provided on the socket body 1 at the position for docking with the movable side 202; the first flexible waterproof material layer 6 and the second flexible waterproof material layer 7 can be fixed in the above two mounting grooves respectively; wherein, the first flexible waterproof material layer 6 is at least partially exposed at the bottom of the receiving notch 2021.

[0064] When the cover 2 is closed, the bottom of the first flexible waterproof material layer 6 can fit tightly against the top of the second flexible waterproof material layer 7, sealing the cable passage 2022 and preventing external water from entering the receiving cavity 203 through the cable passage 2022. When the plug 12 is plugged into the working platform 1013, the power cord 1201 of the plug 12 passes through the cable passage 2022. Based on the flexible deformation of the first and second flexible waterproof material layers 6 and 7, the bottom of the first flexible waterproof material layer 6 can fit tightly against the upper part of the power cord 1201, and the top of the second flexible waterproof material layer 7 can fit tightly against the lower part of the power cord 1201. This allows the waterproof material to fill the gap between the cable passage 2022 and the power cord 1201, preventing external water from entering the receiving cavity 203 through this gap when the plug 12 is plugged in, thus achieving a waterproof effect.

[0065] In one embodiment, reference is made to Figure 2 , Figure 4 and Figure 5 The first flexible waterproof material layer 6 and the second flexible waterproof material layer 7 are silicone material layers. Silicone has good elasticity and weather resistance, and can adhere tightly to the surface of the power cord 1201 to achieve a good waterproof sealing effect.

[0066] In one embodiment, reference is made to Figure 2 , Figure 4 and Figure 5 The first flexible waterproof material layer 6 and the second flexible waterproof material layer 7 are made of sponge. The sponge has excellent compression resilience and can effectively fill the irregular gaps in the wire passage 2022; in addition, the porous structure of the sponge gives it a certain water absorption and buffering capacity, which can absorb a small amount of water when external water enters, thereby improving the waterproof sealing effect.

[0067] In one embodiment, reference is made to Figure 2 , Figure 4 and Figure 5 The first flexible waterproof material layer 6 and the second flexible waterproof material layer 7 are brushes. The brushes can block water through the dense arrangement of bristles, thus achieving a good waterproof sealing effect. At the same time, the deformable nature of the bristles can be used to avoid excessive compression of the power cord 1201.

[0068] In one embodiment, reference is made to Figures 8 to 10 The hinge side 201 has a downwardly extending first flange 2011 at its edge, and the socket body 1 has an upwardly extending second flange 1014. When the cover 2 is placed on the socket body 1, the first flange 2011 engages with the second flange 1014, forming a second mating gap 8 between the first flange 2011 and the second flange 1014. The second mating gap 8 has a first gap channel 801 and a second gap channel 802. The first gap channel 801 is vertically arranged, with its lower end connected to the outside and its upper end connected to the water inlet of the second gap channel 802. The water outlet of the second gap channel 802 is connected to the receiving cavity 203. The second gap channel 802 is horizontally arranged or inclined upwards along a horizontal direction close to the receiving cavity 203.

[0069] like Figure 9 and Figure 10 As shown, the first flange 2011 is disposed on the outer region of the edge of the hinge side 201; the second flange 1014 is disposed on the side wall of the socket body 1 for mating with the hinge side 201, and the second flange 1014 is located in the inner region of the side wall; on the horizontal plane, the first flange 2011 and the second flange 1014 are offset. When the cover 2 is in the closed state, the first flange 2011 is engaged with the outer side of the second flange 1014. At this time, the vertical gap between the first flange 2011 and the second flange 1014 forms the first gap channel 801, and the transverse gap between the second flange 1014 and the inner region of the edge of the hinge side 201 forms the second gap channel 802. The first gap channel 801 and the second gap channel 802 form an inverted L-shaped gap structure.

[0070] Based on the above structural configuration, external water needs to pass through the first gap channel 801 and the second gap channel 802 in sequence before it can flow into the receiving cavity 203. The inverted L-shaped gap structure forces the water to rise first and then turn horizontally. During this process, the kinetic energy of the water will be consumed, and some water can flow back along the original path after hitting the inner wall of the channel, and cannot be continuously supplied inward. Thus, it can effectively prevent external water from entering the receiving cavity 203 through the fitting gap of the hinge side 201.

[0071] Preferably, the second gap channel 802 is inclined upward along the horizontal direction close to the receiving cavity 203, so that the resistance to the water flow along the second gap channel 802 can be further increased based on the effect of gravity, thereby further improving the waterproof effect.

[0072] In one embodiment, reference is made to Figures 8 to 10The socket body 1 is provided with a first baffle 1015. The first baffle 1015 blocks the water outlet of the second gap channel 802 and the working platform 1013. The upper edge of the first baffle 1015 is higher than the water outlet of the second gap channel 802. A first collecting groove 1016 is formed between the first baffle 1015 and the water outlet of the second gap channel 802.

[0073] By setting the first baffle 1015, even if a small amount of water flows into the receiving cavity 203 through the second gap channel 802, the first baffle 1015 can block the water. Based on the height design of the first baffle 1015, the water is unlikely to maintain enough kinetic energy to reach the upper edge of the first baffle 1015 under the action of gravity. Thus, the water will be intercepted by the first baffle 1015 and flow back down into the first collecting channel 1016. It cannot climb over the first baffle 1015 and directly reach the working platform 1013. This can further improve the electrical safety of the working platform 1013 and reduce the risk of short circuits and leakage.

[0074] In one embodiment, reference is made to Figure 8 and Figure 9 The socket body 1 is provided with a first drainage channel 1021; one end of the first drainage channel 1021 is connected to the first collection groove 1016, and the other end of the first drainage channel 1021 is connected to the outside.

[0075] In this embodiment, the water that is intercepted by the first baffle 1015 and accumulates in the first collection channel 1016 can be discharged to the outside of the waterproof socket in a timely manner through the first drainage channel 1021. This can prevent the water from stagnating inside the socket body 1 for a long time, thereby preventing the stagnant water from overflowing out of the first collection channel 1016 and causing safety risks such as short circuit and leakage when the waterproof socket is flipped.

[0076] In one embodiment, reference is made to Figure 4 and Figure 5 The socket body 1 includes an upper housing 101 and a lower housing 102; the upper housing 101 is detachably connected to the lower housing 102, and the upper housing 101 and the lower housing 102 enclose a mounting cavity 1017 for accommodating the conductive component 13; a first platform 1011, a second platform 1012 and a working platform 1013 are disposed on the top of the upper housing 101, and the socket 10131 is correspondingly disposed with the conductive component 13; The joint between the upper housing 101 and the lower housing 102 is provided with at least one waterproof structure (not shown in the figure), which is used to prevent external water from entering the mounting cavity 1017.

[0077] The upper housing 101 and the lower housing 102 can be detachably connected by bolts, snap-fit ​​connections, or other means. The upper housing 101 and the lower housing 102 enclose a closed mounting cavity 1017, which is used to accommodate the conductive component 13. The first platform 1011, the second platform 1012, and the working platform 1013 are all located on the top of the upper housing 101. The insertion hole 10131 on the working platform 1013 corresponds to the position of the conductive component 13 in the mounting cavity 1017, so as to ensure that when the plug 12 is plugged into the working platform 1013, the prongs of the plug 12 can pass through the insertion hole 10131 and connect with the conductive component 13, thereby realizing normal power supply operation.

[0078] The joint between the upper housing 101 and the lower housing 102 refers to the area where their edges come into contact. This joint is provided with at least one waterproof structure to prevent external water from entering the mounting cavity 1017, thus avoiding short circuits, leakage, and other safety risks caused by water contacting the conductive components 13, achieving a waterproof seal. Depending on different design requirements, this waterproof structure can be implemented in various ways, such as by extending the water inlet path, forcing the water to change direction multiple times, or utilizing the water's own gravity for backflow or discharge. This effectively prevents water from entering the mounting cavity 1017 under different water inlet directions and pressure conditions.

[0079] In one embodiment, reference is made to Figure 9 and Figure 11 A third fitting gap 9 is formed between the upper shell 101 and the lower shell 102. The third fitting gap 9 has a third gap channel 901, an expansion chamber 902 and a fourth gap channel 903. The cross-sectional area of ​​the expansion chamber 902 is larger than the cross-sectional area of ​​the third gap channel 901 and the cross-sectional area of ​​the fourth gap channel 903. The inlet end of the third gap channel 901 is connected to the outside, the outlet end of the third gap channel 901 is connected to the bottom of the expansion chamber 902, and the two ends of the fourth gap channel 903 are connected to the top of the expansion chamber 902 and the mounting cavity 1017, respectively.

[0080] This embodiment is the first specific implementation of the waterproof structure between the upper shell 101 and the lower shell 102 in the above embodiments. Specifically, as follows... Figure 11As shown, based on the corresponding protruding and recessed structures within the upper shell 101 and lower shell 102, after the upper shell 101 and lower shell 102 are docked, a third fitting gap 9 can be formed at the joint between the upper shell 101 and lower shell 102. The third fitting gap 9 is sequentially divided into a third gap channel 901, an expansion chamber 902, and a fourth gap channel 903 along the inflow direction of the external water flow. The third gap channel 901 is located below the expansion chamber 902, and the fourth gap channel 903 is located above the expansion chamber 902. The cross-sectional area of ​​the expansion chamber 902 is larger than the cross-sectional areas of the third gap channel 901 and the fourth gap channel 903, thus forming a gap structure that is wide in the middle and narrow at both ends.

[0081] Based on the above configuration, when external water enters the expansion chamber 902 through the third gap channel 901, the water flow velocity decreases rapidly due to the sharp expansion of the flow channel cross-section. The kinetic energy of the water is consumed, and the water gradually accumulates in the expansion chamber 902, causing the water level to rise gradually. The accumulated water can block and buffer the subsequent water entering based on its own surface tension and filling effect, thereby forming a water seal effect, which can effectively reduce the impact force of the water flow. In addition, during the accumulation of water in the expansion chamber 902, the kinetic energy of the water gradually decreases. The water with decreased kinetic energy is difficult to continue to climb upward and flows into the installation cavity 1017 through the fourth gap channel 903. Under the action of gravity, the water accumulated in the expansion chamber 902 will naturally flow back to the outside along the third gap channel 901.

[0082] As can be seen, by setting the third fitting gap 9 between the upper shell 101 and the lower shell 102 as a flow channel structure that is wide in the middle and narrow at both ends, the water flowing into the third fitting gap 9 can be slowed down, accumulated and form a water seal effect. At the same time, the water can be backflowed by gravity, thereby effectively preventing external water from entering the mounting cavity 1017 and improving the waterproof performance of the joint between the upper shell 101 and the lower shell 102.

[0083] In one embodiment, reference is made to Figure 12 and Figure 13The upper housing 101 has a downwardly extending third flange 1018, and the lower housing 102 has an upwardly extending fourth flange 1022; the third flange 1018 is engaged with the fourth flange 1022, and a fourth mating gap 10 is formed between the third flange 1018 and the fourth flange 1022; the fourth mating gap 10 has a fifth gap channel 1001, a sixth gap channel 1002 and a seventh gap channel 1003, the fifth gap channel 1001 is lower than the seventh gap channel 1003, the sixth gap channel 1002 connects the water outlet end of the fifth gap channel 1001 and the water inlet end of the seventh gap channel 1003, the water inlet end of the fifth gap channel 1001 is connected to the outside, and the water outlet end of the seventh gap channel 1003 is connected to the mounting cavity 1017.

[0084] This embodiment is a second specific implementation of the waterproof structure between the upper shell 101 and the lower shell 102 in the above embodiments. Specifically, as follows... Figure 12 and Figure 13 As shown, the third flange 1018 is located on the outer side of the edge of the upper housing 101, and the fourth flange 1022 is located on the inner side of the edge of the lower housing 102. On the horizontal plane, the third flange 1018 and the fourth flange 1022 are offset. When the upper housing 101 and the lower housing 102 are docked, the third flange 1018 engages with the outer side of the fourth flange 1022. At this time, the transverse gap between the third flange 1018 and the outer side of the edge of the lower housing 102 forms the fifth gap channel 1001, the vertical gap between the third flange 1018 and the fourth flange 1022 forms the sixth gap channel 1002, and the transverse gap between the fourth flange 1022 and the inner side of the edge of the upper housing 101 forms the seventh gap channel 1003. The fifth gap channel 1001, the sixth gap channel 1002, and the seventh gap channel 1003 are sequentially connected to form a Z-shaped gap structure.

[0085] Based on the above structural design, when external water flows in through the fifth gap channel 1001, the Z-shaped gap structure can force the external water to make multiple turns along the preset path, thereby consuming the kinetic energy of the water and increasing the difficulty of water seeping in along the fourth mating gap 10. At the same time, the water is prone to backflow due to gravity during the turning flow along the fourth mating gap 10, making it difficult to continuously advance inward. This can effectively block external water from entering the installation cavity 1017 and achieve a waterproof effect.

[0086] In one embodiment, reference is made to Figures 12 to 14The lower housing 102 is provided with a partition 1023 and a second drainage channel 1024; the partition 1023 and the fourth flange 1022 are spaced apart, and the partition 1023 and the fourth flange 1022 enclose to form a second collection groove 1025, the opening of the second collection groove 1025 faces upward and is connected to the water outlet end of the seventh gap channel 1003; the first end of the second drainage channel 1024 is connected to the second collection groove 1025, and the second end of the second drainage channel 1024 is connected to the outside.

[0087] Specifically, the partition 1023 is disposed between the fourth flange 1022 and the conductive component 13 located in the central region, and the space between the partition 1023 and the fourth flange 1022 constitutes the second current collection channel 1025.

[0088] By setting up the baffle 1023, even if a small amount of water flows into the mounting cavity 1017 through the fourth mating gap 10, the baffle 1023 can block the water, preventing it from further penetrating into the area where the conductive component 13 is located. The water intercepted by the baffle 1023 will flow back down into the second collection tank 1025. The water accumulated in the second collection tank 1025 can be discharged to the outside of the waterproof socket in a timely manner through the second drainage channel 1024. This can prevent water from stagnating in the mounting cavity 1017 for a long time, thus preventing the stagnant water from overflowing from the second collection tank 1025 and causing a short circuit, leakage, or other safety risks when the waterproof socket is flipped.

[0089] In one embodiment, reference is made to Figure 14 and Figure 15 The first end of the second drainage channel 1024 is connected to the bottom wall of the second collection trough 1025; The lower housing 102 is also provided with a second baffle 1026. The two ends of the second baffle 1026 are connected to the partition 1023 and the fourth flange 1022 respectively. The second baffle 1026 covers the top of the first end of the second drainage channel 1024.

[0090] In this embodiment, when external water with a certain pressure is supplied upward into the second collection tank 1025 through the second drainage channel 1024, this part of the water can be blocked by the second baffle 1026 above the second drainage channel 1024 and flow downward back, thereby preventing external water from entering the mounting cavity 1017 in reverse through the second drainage channel 1024, and further improving the waterproof effect of the socket body 1.

[0091] In one embodiment, reference is made to Figure 16 and Figure 17 The partition 1023 has a horizontal through first opening 10231; the bottom wall of the lower housing 102 has a vertical through second opening 1027, which is located on the side of the partition 1023 away from the second collection channel 1025. The lower housing 102 is also provided with a cover structure 1028, which is located on the side of the partition 1023 facing away from the second collection groove 1025, and the cover structure 1028 is connected to the bottom wall of the lower housing 102. The cap structure 1028 has a hollow inner cavity 10281, which is connected to the first opening 10231 and the second opening 1027 to form a second drainage channel 1024.

[0092] Specifically, such as Figure 16 and Figure 17 As shown, taking the partition 1023 as an example of being arranged around the lower housing 102 circumferentially, the second opening 1027 is disposed within the enclosed area of ​​the partition 1023, and the second opening 1027 corresponds to the first opening 10231 on the partition 1023; the cover structure 1028 is a hollow housing, the cover structure 1028 is located within the enclosed area of ​​the partition 1023, and the cover structure 1028 is connected to both the partition 1023 and the bottom wall of the lower housing 102. The side of the cover structure 1028 is opposite to the first opening 10231, and the bottom of the cover structure 1028 is opposite to the second opening 1027, so that the first opening 10231 and the second opening 1027 are connected through the hollow inner cavity 10281 of the cover structure 1028. At this time, the first opening 10231, the hollow inner cavity 10281 and the second opening 1027 together constitute a second drainage channel 1024 with a turning part.

[0093] Based on the above settings, such as Figure 16 As shown, when external water flows upward into the hollow inner cavity 10281 through the second opening 1027, the external water can be blocked by the top of the sealing structure 1028 (i.e., the upper cavity wall of the hollow inner cavity 10281) and its flow direction is changed, and the kinetic energy of the water is consumed. After the water has changed its flow direction and its kinetic energy has been consumed, it is difficult for the water to continue to be transported upward through the first opening 10231 and the second collection channel 1025. This makes it difficult for the water to seep into the installation cavity 1017 through the gap between the upper shell 101 and the lower shell 102. In this way, the problem of external water flowing backward through the second drainage channel 1024 is effectively avoided, and the waterproof effect of the socket body 1 is further improved.

[0094] In one embodiment, reference is made to Figures 18 to 21 The upper housing 101 has a downwardly extending fifth flange 1019, and the lower housing 102 has an upwardly opening mating groove 1029; the fifth flange 1019 is inserted into the mating groove 1029.

[0095] Based on the above configuration, even if external water enters the gap between the fifth flange 1019 and the mating groove 1029, the water needs to continue to penetrate inward along the tortuous path between the fifth flange 1019 and the mating groove 1029. This consumes the kinetic energy of the water flow and causes the water to flow back under the action of gravity, thereby increasing the difficulty for the water to further penetrate into the mounting cavity 1017 and achieving a waterproof effect.

[0096] In one embodiment, reference is made to Figure 18 and Figure 19 The fifth flange 1019 has a first side portion 10191 and a second side portion 10192 disposed opposite to each other, and the mating groove 1029 has a first side wall 10291 and a second side wall 10292 disposed opposite to each other; there is an interference fit between the first side portion 10191 and the first side wall 10291, and there is an interference fit between the second side portion 10192 and the second side wall 10292.

[0097] like Figure 19 As shown, in the groove width direction of the mating groove 1029, the width dimension of the fifth flange 1019 is greater than the groove width dimension of the mating groove 1029. When the fifth flange 1019 is inserted into the mating groove 1029, both the fifth flange 1019 and the mating groove 1029 undergo elastic deformation, causing the first side portion 10191 to press against the first side wall 10291, and the second side portion 10192 to press against the second side wall 10292. This creates a sealing effect on both sides of the fifth flange 1019 and the mating groove 1029, preventing external water from entering the mounting cavity 1017 through the joint between the fifth flange 1019 and the mating groove 1029, thus achieving a waterproof effect.

[0098] In one embodiment, reference is made to Figure 20 and Figure 21 The fifth flange 1019 has a first side portion 10191 and a second side portion 10192 disposed opposite to each other, and the mating groove 1029 has a first side wall 10291 and a second side wall 10292 disposed opposite to each other; a fifth mating gap 11 is formed between the first side portion 10191 and the first side wall 10291, the fifth mating gap 11 is in communication with the outside, and there is an interference fit between the second side portion 10192 and the second side wall 10292.

[0099] In this embodiment, the fifth flange 1019 and the mating groove 1029 adopt a differential mating structure. Specifically, as follows... Figure 21As shown, the first side portion 10191 and the first side wall 10291 are fitted with a clearance fit. The fifth fitting gap 11 formed by this clearance fit communicates with the outside to guide any external water that may enter along a predetermined path. The second side portion 10192 and the second side wall 10292 have an interference fit, meaning the second side portion 10192 can be pressed against the second side wall 10292 based on elastic deformation to form a sealed structure. When external water flows in through the fifth fitting gap 11, the water will be blocked by the interference fit between the second side portion 10192 and the second side wall 10292, preventing it from further penetrating into the mounting cavity 1017, thus achieving a waterproof effect.

[0100] In one embodiment, reference is made to Figures 18 to 21 A liquid collection cavity 10293 is formed between the bottom of the groove 1029 and the fifth flange 1019. The liquid collection cavity 10293 can be used to contain a small amount of water flowing in through the joint between the first side portion 10191 and the first side wall 10291, and the liquid collection cavity 10293 can also be used to contain water flowing back from the joint between the second side portion 10192 and the second side wall 10292, so as to prevent water from seeping into the mounting cavity 1017 and to provide space for subsequent water discharge.

[0101] In one embodiment, reference is made to Figure 20 and Figure 21 The lower housing 102 is provided with a third drainage channel 10294; one end of the third drainage channel 10294 is connected to the liquid collection chamber 10293, and the other end of the third drainage channel 10294 is connected to the outside.

[0102] The water accumulated in the collection chamber 10293 can be discharged to the outside of the waterproof socket in a timely manner through the third drainage channel 10294, thus avoiding the water from staying inside the socket body 1 for a long time.

[0103] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
