Description

Technical Field

[0001] The present invention relates to the technical field of electronic connectors, and in particular to a socket and connector combination. Background Art

[0002] As the demand for electrical equipment in humid environments (such as kitchens, bathrooms, and outdoors) increases, the reliability of socket waterproofing becomes critical.

[0003] To prevent rainwater or liquids from seeping into the sockets and causing short circuits or electric shock, sockets with retractable covers are currently commonly used. These sockets have a waterproof cover (such as a flip-up or push-pull cover) placed over the sockets. When not in use, the cover is closed over the sockets, forming a physical barrier to isolate them from external liquids. When in use, the user manually opens the cover and inserts a plug into the socket to complete the connection.

[0004] However, this solution has the following limitations: The conductive circuitry of existing sockets (such as the socket, contacts, and other live components) remains energized while the lid is open or a plug is inserted, lacking a disconnect mechanism linked to the lid's opening and closing. When the user opens the lid to insert a plug, if the ambient humidity is high (such as on rainy days) or if rain splashes into the socket after the lid is opened, the exposed conductive components may leak due to residual liquid or direct contact with a film of water (the conductivity of water reduces insulation). Furthermore, if the user's hands are damp or the plug surface is wet when the plug is inserted, contact between the live conductive components and wet hands or plug could easily cause electric shock or arcing, posing a safety hazard. Summary of the Invention

[0005] The main purpose of the present invention is to provide a socket and connector combination, aiming to improve the waterproof reliability and conductive stability of the socket in a humid environment.

[0028] The technical solution of the present invention mainly solves the problems of leakage and short circuit caused by water seepage in the socket under rainy conditions. When the plug is inserted into the first position, the sealing sleeve rises along the socket and directly covers the pin of the sealed plug. At this time, the conductive component and the plug remain in a non-conductive state, ensuring that the pin is physically isolated by the sealing sleeve before contacting the conductive component. This effectively avoids the risk of leakage caused by external liquids (such as rainwater and moisture) contacting the pin during the insertion process, and solves the safety hazard caused by the "synchronization or lag of sealing and conductivity" of traditional sockets. Only after the sealing sleeve completes the sealing of the pin, the plug is further inserted into the second position and electrically connected to the conductive component, ensuring that during the entire process of plug insertion in a humid environment, the live parts are only energized after the pin is completely sealed, significantly reducing the probability of electric shock in situations such as wet hand insertion and liquid splashing. By sealing in the first position and conducting electricity in the second position, it is ensured that when the plug is inserted: in the first stage (sealing first), when the plug is inserted into the first position, the sealing sleeve is first driven to extend and cover the sealing plug pin, isolating the plug from external water sources; in the second stage (conductivity lags), the circuit is not turned on until the plug is further inserted into the second position, avoiding the risk of "the circuit is turned on when the pin is not sealed". Since the conductive component is only electrically connected to the plug when the plug is inserted into the second position, the internal circuit of the socket naturally remains in a non-conductive state (normal power off) when there is no plug. Compared with the traditional socket design of "the socket is always charged", this solution avoids the risk of internal short circuit or accidental contact with the conductor due to liquid seeping into the socket when idle, and solves the problem of leakage or electric shock caused by rainwater contacting the live parts of the traditional socket during insertion, further improving the safety of use in humid environments.

[0036] The present invention provides a socket and connector combination, aiming to improve the waterproof reliability and conductive stability of the socket in a humid environment.

[0037] See also Figures 1 to 3 In one embodiment of the present invention, the socket 100 includes a housing 10, a sealing sleeve 221a disposed in the housing 10, and a conductive component 40 disposed in the housing 10. The housing 10 is provided with a socket 11 for inserting a pin 201 of a plug 200. The sealing sleeve 221a is movably disposed in the housing 10 and can be raised and lowered along the axial direction of the socket 11. The plug 200 has a first position and a second position during insertion into the housing 10. When the plug 200 is inserted into the first position, the sealing sleeve 221a rises along the socket 11 and sleeves the pin 201 of the plug 200, at which time the conductive component 40 and the plug 200 remain in a non-conductive state. After the sealing sleeve 221a completes the sealing of the pin 201, the plug 200 is inserted into the second position and electrically connected to the conductive component.

[0038] Reference Figure 10 When the plug 200 is inserted into the first position, the sealing sleeve 221a rises along the socket and directly covers the pin 201 of the sealed plug 200. At this time, the conductive component 40 and the plug 200 remain in a non-conductive state, ensuring that the pin 201 is physically isolated by the sealing sleeve 221a before contacting the conductive component, effectively avoiding the risk of leakage caused by external liquid (such as rainwater or moisture) contacting the pin 201 during the insertion process, and solving the safety hazard caused by the "synchronization or lag of sealing and conduction" of traditional sockets.

[0039] Combine Figure 10 and Figure 11 It is worth mentioning that only after the sealing sleeve 221a completes the sealing of the plug 201, the plug 200 is further inserted into the second position and electrically connected to the conductive component 40 (when the plug 200 is in the process of moving from the first position to the second position, the end face of the sealing sleeve 221a will abut the end face of the plug 200, ensuring that the plug 201 is fully inserted into the sealing sleeve 221a). This ensures that during the entire insertion process of the plug 200 in a humid environment, the live parts are energized only after the plug 201 is completely sealed, significantly reducing the probability of electric shock in situations such as plugging and unplugging with wet hands or liquid splashing.

[0040] By sealing in the first position and conducting electricity in the second position, the socket ensures that when plug 200 is inserted: in the first stage (sealing first), when plug 200 is inserted into the first position, sealing sleeve 221a is first driven to extend and cover plug 200 pin 201, isolating plug 201 from external water sources; in the second stage (conductivity delayed), the circuit is not connected until plug 200 is further inserted into the second position, avoiding the risk of "circuit conduction when pin 201 is not sealed." Because conductive component 40 is only electrically connected to plug 200 when plug 200 is inserted into the second position, the internal circuit of the socket naturally remains non-conductive (normally powered off) when plug 200 is absent. Compared to traditional socket designs where the "jack is always live," this solution avoids the risk of internal short circuits or accidental contact with the conductive part due to liquid seeping into the socket when idle. It also solves the problem of leakage or electric shock caused by rainwater contacting live components during insertion, further improving safety in humid environments.

[0041] Specifically, the housing 10, the main support structure of the socket, is made of an insulating material (such as high-temperature-resistant ABS or PC). Its front surface is provided with at least one insertion hole for the plug 200. The diameter of the insertion hole is adapted to the pin 201 of the plug 200, and the axial extension direction of the insertion hole (i.e., the insertion direction of the plug 200) aligns with the arrangement of the sealing sleeve 221a and the conductive assembly 40 within the housing 10, ensuring that the sealing and conductive actions are triggered sequentially when the plug 200 is inserted.

[0042] Combine Figure 3 and Figure 4 The sealing sleeve 221a is a resilient, hollow cylindrical structure (e.g., made of silicone or rubber) that is movably disposed within the housing 10 and coaxially sleeved with the jack (i.e., the extension of the jack into the interior of the housing 10). The outer wall of the sealing sleeve 221a is slidably connected to the housing 10 via a guide structure (e.g., an axial groove provided on the inner wall of the housing 10, or a slider provided on the outer periphery of the sealing sleeve 221a), allowing it to be raised and lowered along the axial direction of the jack (i.e., the direction in which the plug 200 is inserted).

[0043] Combine Figure 10 When the latch 201 is inserted into the sealing sleeve 221a, the inner wall of the sealing sleeve 221a can fit tightly against the outer periphery of the latch 201 (41) to form a radial seal.

[0044] Lifting trigger: The initial position of the sealing sleeve 221a (when the plug 200 is not inserted) is the "low position", and its front end surface (the end surface close to the socket) is flush with or slightly lower than the socket. When the plug 200 is inserted, it first contacts the front end surface of the sealing sleeve 221a and drives it to rise through axial thrust.

[0045] Combine Figure 3 and Figure 5 、 Figure 6The conductive component 40 includes a fixed contact 43 for connecting to the external circuit and a conductive spring 42 for contacting the plug pin 201 of the plug 200. Both are made of a conductive metal material (such as phosphor bronze) and are spaced apart at the rear end of the sealing sleeve 221a (i.e., the side away from the socket). The conductive spring 42 has elastic reset capability and remains separated from the fixed contact 43 in normal operation (when no plug 200 is inserted). Only when the plug 200 is inserted to a specific position does the conductive spring 42 deform and contact the fixed contact 43, achieving circuit continuity. Of course, in other embodiments, the plug pin 201 of the plug 200 can only contact and connect with the conductive component 40 when inserted into the second position; or, in the second position, other methods can be used to facilitate contact and connection between the two conductive components.

[0046] In summary, based on the above description, those skilled in the art can implement this solution through conventional mechanical design methods. For example, the raising and lowering of the sealing sleeve 221a can be directly driven by the thrust of the plug 200 (without the need for an additional power source), and the conduction of the conductive component 40 can be achieved through the mechanical compression of the pin 201. The definition of the two positions can be controlled by adjusting the length of the sealing sleeve 221a or the arrangement distance of the conductive components 40. Therefore, this solution does not rely on special materials or complex structures and has clear feasibility.

[0047] Reference Figure 10 and Figure 11 Furthermore, when the plug 200 switches from the second position to the first position, the conductive assembly 40 is electrically disconnected from the plug 200. When the plug 200 switches from the second position (conductive state) to the first position, the conductive assembly 40 is first electrically disconnected from the plug 200, while the sealing sleeve 221a maintains its seal on the plug pin 201. The sealing sleeve 221a is only released when the plug 200 is further removed from the first position. This avoids the problem of live plug pin 201 being exposed, as is often the case with conventional sockets that "release the seal before powering off" during removal (for example, in humid environments, if the plug 201 is released from the seal before powering off, residual moisture could cause leakage or arcing). This ensures that "electrical isolation" and "physical isolation" work together throughout the entire plugging and unplugging process. When the plug 200 is removed from the first position, the sealing sleeve 221a releases its seal on the plug pin 201. Ensure that during the process of unplugging the plug 200, the pin 201 is always in a "sealed state" until the circuit is completely cut off, fundamentally avoiding the risk of electric shock at the moment of unplugging. It is especially suitable for scenes with high requirements for anti-electric shock level (such as children's sockets and bathroom sockets). If the user accidentally touches the plug 200 when it is not completely unplugged (such as pausing in the middle when the hands are wet), since the conductive component 40 is powered off and the seal is still not released, the risk of electric shock can be effectively avoided, reducing safety accidents caused by improper operation.

[0048] Reference Figures 3 to 6 and Figure 9 Specifically, a base 21 and a lifting plate 22 are provided within the housing 10. A sealing sleeve 221a is mounted on the lifting plate 22, which is movably mounted within the base 21. The base 21 serves as a fixed support structure, forming a sliding fit with the lifting plate 22 movably mounted therein (e.g., via guide structures such as guide rails and slideways). This restricts the sealing sleeve 221a to axial movement within the jack, thus preventing seal failure due to misalignment (e.g., in conventional non-guided designs, the sealing sleeve 221a may shift radially due to angular deviations in the insertion of the plug 200, resulting in a loose seal on the plug 201 and the possibility of liquid infiltration).

[0049] Specifically, the conductive component 40 includes a conductive socket 41 provided on the base 21, a conductive spring 42 electrically connected to the conductive socket 41, and a fixed contact 43 fixed to the housing 10; the conductive socket 41 has a plug cavity 411 for inserting the pin 201 of the plug 200, and the conductive spring 42 and the fixed contact 43 remain separated under normal circumstances.

[0050] Reference Figure 5 and Figure 6 and Figure 9 Specifically, a linkage drive assembly 30 and a trigger member 23 that can move relative to the base 21 are provided in the base 21. The linkage drive assembly 30 is configured to: in response to the action of the plug 200 being inserted into the first position, drive the lifting plate 22 to drive the sealing sleeve 221a to rise along the insertion hole; when the plug 200 is inserted from the first position to the second position, the lifting plate 22 drives the trigger member 23 to move through the linkage drive assembly 30, and the trigger member 23 presses the conductive spring piece 42, so that the conductive spring piece 42 contacts the fixed contact piece 43 to conduct the circuit.

[0051] Combine Figure 3 and Figure 7 、 Figure 8Furthermore, to actively drain infiltrated liquid and prevent water accumulation within the housing 10, the housing 10 is provided with a drain port 12. A drainage channel 211 is also provided within the housing 10, connecting the socket and the drain port 12. The drainage channel 211 connects the plug cavity 411 and the drain port 12. The drainage channel 211 is configured to direct liquid within the socket to the drain port 12. As the sole access point for plugging and unplugging the plug 200, the socket is inevitably exposed to external liquids (such as rain, splashing water, and condensation in humid environments). Even if the sealing sleeve 221a seals the plug 201, a small amount of liquid may still seep into the housing 10 through the gap between the inner wall of the socket and the sealing sleeve 221a. Liquid that has seeped into the socket can flow directly to the drain port 12 through the channel, avoiding accumulation at the bottom of the socket. The plug cavity 411 is the core area where the conductive socket 41 contacts the plug 201. If liquid accumulates there, it can easily cause a short circuit or metal corrosion. Drain channel 211 connects the connector cavity 411 to the drain port 12, preferentially draining liquid around the conductive components and eliminating potential safety hazards at the source. Drain channel 211 can be integrally formed by injection molding through the housing 10 (e.g., by providing a grooved channel on the inner wall of the base 21 or the housing 10).

[0052] Combine Figures 9 to 11 Specifically, the socket 100 includes a base assembly 20, a housing 10 having an insertion hole 11 and a drain outlet 12; the base assembly 20 is arranged in the housing 10, and the base assembly 20 includes a base 21, a lifting plate 22 and a trigger 23 movably arranged in the base 21, a linkage drive assembly 30 and a conductive assembly 40 arranged in the base 21; the base 21 is provided with a drainage channel 211 connecting the insertion hole 11 and the drain outlet 12; the lifting plate 22 has a sealing sleeve 221a that passes through the insertion hole 11, and under normal circumstances, the end of the sealing sleeve 221a abuts against the edge of the insertion hole 11 for sealing; the conductive assembly 40 includes a conductive socket 41 provided in the base 21, a conductive spring 42 electrically connected to the conductive socket 41, and a fixed conductive member 40 provided in the housing 10 Contact 43; the conductive socket 41 has an inserting cavity 411 connected to the inner cavity of the sealing sleeve 221a, and the drainage channel 211 connects the inserting cavity 411 and the drain outlet 12; the conductive spring 42 is normally separated from the fixed contact 43; wherein, when the plug 200 is inserted into the first position, the linkage drive component 30 responds to the insertion of the plug 200 and drives the lifting plate 22 to move up along the base 21, and the sealing sleeve 221a extends out of the socket 11 and is sleeved on the sealing plug 200 pin 201; when the plug 200 is inserted into the second position, the plug 200 presses the sealing sleeve 221a to drive the linkage drive component 30, driving the trigger 23 to press the conductive spring 42, so that the conductive spring 42 contacts the fixed contact 43 to conduct the circuit.

[0053] The technical solution of the present invention primarily solves the problems of leakage and short circuit caused by water seepage in the socket 100 under rainy conditions. By controlling the conductive sequence from the first sealing position to the second position of the linkage drive assembly 30, it ensures that when the plug 200 is inserted: in the first stage (sealing priority), when the plug 200 is inserted into the first position, the sealing sleeve 221a is first driven to extend and sheath the plug 201 of the sealing plug 200, isolating the plug 201 from external water sources; in the second stage (conductivity lag), when the plug 200 is further inserted into the second position, the trigger member 23 compresses the conductive spring 42 and the fixed contact 43 to conduct the circuit, avoiding the risk of "the circuit is already conducted when the plug 201 is not sealed" and solving the leakage or electric shock problem caused by rainwater contacting the live parts during the insertion process of the traditional socket 100. Furthermore, the drainage channel 211 connects the plug-in cavity 411 of the conductive socket 41 with the drain port 12 of the housing 10, allowing water to be quickly drained to the outside through the drainage channel 211. This prevents rainwater from accumulating around metal components such as the conductive socket 41 and the conductive spring 42, reduces the problem of poor contact or reduced insulation performance caused by metal corrosion, and reduces the risk of short circuits caused by accumulated water. Furthermore, the conductive spring 42 and the fixed contact 43 remain normally separated when there is no plug 200, and the internal circuit of the socket 100 is in a disconnected state. Compared to the charged design of the traditional socket 100, this structure avoids the risk of short circuits or accidental contact of charged components in the socket 11 due to rainwater infiltration when idle, further improving safety. In this way, this solution significantly improves the safety and reliability of the socket 100 in outdoor or humid environments through the synergistic effects of dynamic sealing, active drainage, and normal power off.

[0054] Regarding the linkage drive assembly 30.

[0055] Combine Figure 5 and Figure 6 The linkage drive assembly 30 includes a pusher 31 directly driven by the latch 201 . The pusher 31 is set corresponding to the latch 201 . The pusher 31 is acted upon by the latch 201 to move the lifting plate 22 . One pusher 31 is independently set corresponding to one latch 201 .

[0056] In one embodiment, the pusher 31 is of a sliding type. The pusher 31 is a slider that can slide laterally along the base 21. The surface of the pusher 31 is provided with a contact surface (such as a plane, a slope or a groove) that matches the pin 201. When the pin 201 is inserted, its front end directly presses the contact surface (such as a slope) of the slider, pushing the slider to slide laterally along the base 21; the slider is connected to the linkage drive component 30 (such as a gear, a rack or a connecting rod) through a boss or a connecting rod at the tail, converting the lateral sliding into the action of the linkage drive component 30.

[0057] In one embodiment, the pusher 31 is a rotating lever or cam that can rotate around a fixed axis. One end of the pusher 31 is exposed in the socket 11 (contacting the latch 201), and the other end is connected to the linkage drive assembly 30. When the latch 201 is inserted, the exposed end of the lever is pressed to rotate around the axis; the other rotating end pushes the linkage drive assembly 30 (such as a gear, a rocker arm, etc.) through a boss or a connecting rod to achieve drive transmission.

[0058] In one embodiment, the pusher 31 is an L-shaped rigid member: the horizontal section is directly pushed by the latch 201; the vertical section serves as both the lifting mechanism and the trigger member 23; when the latch 201 pushes the horizontal section: the upper end of the vertical section first pushes the lifting plate 22 upward to complete the sealing; then the lower end of the vertical section presses the conductive spring 42 to contact the fixed contact 43.

[0059] Furthermore, the linked drive assembly 30 includes a first drive member 32 and a second drive member 33 arranged crosswise. The first drive member 32 includes a first push portion 321 and a first connection seat 322 connected to the first push portion 321; the second drive member 33 includes a second push portion 331 and a second connection seat 332 connected to the second push portion 331. Under the action of the latch 201, the first push portion 321 moves toward the second connection seat 332; and the second push portion 331 moves toward the first connection seat 322. The first drive member 32 and the second drive member 33 cooperate to lift the lifting plate 22. Through the crosswise arrangement of the two drive members and the two drive members, the independent driving forces of the two latches 201 are converted into a synchronous lifting action of the lifting plate 22.

[0060] In one embodiment, the first and second drive members 32, 33 are cross-hinged connecting rods (similar to a pair of scissors forks), connected at the center by a pivot. A first pusher 321 drives one end of the first connecting rod toward the second connecting rod, while a second pusher 331 drives one end of the second connecting rod toward the first connecting rod. When the two connecting rods are driven toward each other by the pushers, the height of the intersection (the pivot) rises, thereby raising the lift plate 22 connected to the intersection. When the plug 200 is removed, the connecting rods move in the opposite direction, lowering the intersection and restoring the lift plate 22.

[0061] In one embodiment, the first and second driving members 32, 33 are transversely sliding sliders arranged crosswise (e.g., at an angle of 45° to 60°). The sliders have inclined surfaces on their tops (inclined in opposite directions), while the bottom of the lift plate 22 has matching inclined surfaces. A first pusher 321 drives the first slider toward the second slider, while a second pusher 331 drives the second slider toward the first slider. The inclined surfaces of the two sliders simultaneously press against the inclined surface at the bottom of the lift plate 22, converting lateral sliding movement into longitudinal lift of the lift plate 22. The force decomposition of the inclined surfaces amplifies the driving force (converting a small lateral displacement into a large longitudinal lift). The crosswise arrangement of the sliders also balances pressure on both sides.

[0062] Combine Figure 5 and Figure 6 In this embodiment, the pushing member 31 also includes a first sliding member 34 movably arranged on the first connecting seat 322 and a second sliding member 35 movably arranged on the second connecting seat 332. The first pushing portion 321 cooperates with the second connecting seat 332 to push the second sliding member 35, and the second pushing portion 331 cooperates with the first connecting seat 322 to push the second sliding member 35; the first sliding member 34 and the second sliding member 35 are lifted at the same time to drive the lifting plate 22 to rise.

[0063] Specifically, a guide constraint is provided within the first connecting seat 322 for the first sliding member 34, restricting its movement to a specific direction. Similarly, the movement direction of the second sliding member 35 is also constrained within the second connecting seat 332. For example, a vertical guide rail (e.g., a T-shaped guide rail or a rectangular guide rail) is provided on the inner wall of the first connecting seat 322, and a groove matching the guide rail is provided on the outer wall of the first sliding member 34. The guide rail and the groove form a sliding pair, restricting the first sliding member 34 to movement only along the guide rail direction. Alternatively, the inner wall of the first connecting seat 322 is machined into a sliding groove, and the first sliding member 34 is provided with a slider matching the sliding groove (or the slider is configured as an end portion). The slider is embedded in the sliding groove, and the sliding member is constrained by the groove wall to move only along the length of the groove.

[0064] Combine Figure 10 When the plug 200 is inserted into the first position, the pin 201 presses the first pushing portion 321 and the second pushing portion 331 respectively, driving the two pushing portions to move away from each other. When the first pushing portion 321 moves, its end contacts the specific structure (such as the inclined surface or protrusion) of the second connecting seat 332 and applies a thrust. Since the second connecting seat 332 and the first connecting seat 322 of the first driving member 32 are arranged crosswise, the thrust is transmitted through the second connecting seat 332 and converted into an upward driving force for the first sliding member 34 in the first connecting seat 322, forcing the first sliding member 34 to move vertically upward along the first connecting seat 322.

[0065] Similarly, when the second pusher 331 moves, its end contacts a specific structure (e.g., an inclined surface or protrusion) of the first connection base 322 and applies a thrust. This thrust is transmitted through the first connection base 322 and converted into an upward driving force on the second sliding member 35 within the second connection base 332, forcing the second sliding member 35 to move vertically upward along the second connection base 332.

[0066] When the first sliding member 34 and the second sliding member 35 move to the top, the top ends of the two members simultaneously contact the bottom of the lifting plate 22 (or are connected through a connecting rod or a boss), and jointly apply an upward thrust to drive the lifting plate 22 to move vertically upward, and finally the sealing sleeve 221a extends out of the socket 11 and is sleeved on the outer wall of the latch 201 to complete the sealing of the latch 201.

[0067] In this way, the first and second sliders 34 and 35 move upward synchronously via the intersecting pusher and connector structures, preventing tilting or jamming of the lift plate 22, which could occur if driven from one side. The symmetrical thrust of the two sliders balances the forces on the lift plate 22, ensuring that it moves strictly in the vertical direction. This improves the fit precision between the sealing sleeve 221a, the receptacle 11, and the latch 201 (for example, preventing a leaky seal due to tilting).

[0068] Furthermore, by converting the lateral insertion force (or oblique force) of the pin 201 into the vertical lifting force of the sliding member. The cross-matching design shortens the force transmission path (reduces the intermediate transmission links), reduces mechanical losses, and improves the driving efficiency (that is, the small displacement of the insertion of the pin 201 can be converted into a large lifting amount of the lifting plate 22). In addition, even if the insertion depths of the two pins 201 are slightly different, the pushing part can still compensate for the error through the matching of the connecting seat, avoiding the failure of the action caused by the asynchronous insertion of the pin 201, and improving the reliability of the socket 100 in complex usage scenarios. In addition, the nested design of the first connecting seat 322, the second connecting seat 332 and the sliding member (the sliding member is movably arranged in the connecting seat) saves lateral space, and the cross-arranged driving members further reduce the overall volume of the linkage drive assembly 30, making the product structure compact, especially suitable for small household or outdoor sockets 100 with strict size requirements.

[0069] Specifically, the contact surfaces between the first pusher 321 and the second connection seat 332, and between the second pusher 331 and the first connection seat 322, are inclined, curved, or stepped surfaces, to convert the lateral / diagonal movement of the pusher into vertical movement of the slider. For example, the end of the pusher may be inclined, and the corresponding position of the second connection seat 332 may be a matching inclined. When the two contact, the force decomposition effect of the inclined surfaces generates a vertical force component, driving the slider upward.

[0070] Specifically, the tops of the first and second sliders 34, 35 need to be designed as flat surfaces, bosses, or spherical heads to ensure stable contact with the bottom of the lift plate 22. A flat surface increases the contact area (reducing pressure and preventing wear); a spherical head design can adapt to slight tilts of the lift plate 22 (compensating for installation errors through spherical contact). In this embodiment, the first and second sliders 34, 35 are cylindrical.

[0071] Reference Figure 5 and Figure 6 To ensure that the lifting member and the pusher automatically return to their original positions after the plug 200 is removed, an elastic return member 60 is provided between the first and second drive members 32, 33. This member is configured as a return spring (e.g., a compression spring or a tension spring) secured between the connector and the pusher. When the plug 200 is removed, the spring's force forces the pusher to return to its original position.

[0072] Reference Figure 4 Specifically, an elastic return member 60 is disposed between the housing 10 and the lifting plate 22. This member is used to reset the lifting plate 22 when the plug 200 is removed. The elastic return member 60 is configured as a spring. The upper housing has a spring cavity for mounting the spring, and the lifting plate 22 has a spring stop for securing the spring. A spring is installed at each end of the lifting plate 22. When the plug 200 is removed, the spring force causes the lifting member to return.

[0073] Combine Figure 3 Specifically, a guide structure is provided between the lifting plate 22 and the base 21. In this embodiment, the guide structure is an insert plate provided at the bottom of the lifting plate 22 and a slot provided at the base 21; in other embodiments, the guide column and the guide groove can be matched, or the slider and the slide groove can be matched, etc.

[0074] Regarding the installation and matching relationship between the linkage drive assembly 30 (pushing part, connecting seat) and the conductive socket 41 and the trigger member 23.

[0075] Specifically, the base 21 is provided with a fixing portion 212, onto which the conductive socket 41 is mounted. The conductive socket 41 has a clearance opening 412 that connects to the insertion cavity 411. The first and second pusher portions 321, 331 are partially positioned within the corresponding conductive sockets 41 through the clearance opening 412. The conductive socket 41 is secured to the base 21 via the fixing portion 212, and the clearance opening 412 provides space for the pusher portion to partially extend into the insertion cavity 411 of the conductive socket 41. This reduces the overall size of the linkage drive assembly 30, resulting in a compact product structure and resolving the conflict between the pusher portion needing to be close to the latch 201 to receive the driving force and the space required for the conductive socket 41.

[0076] The avoidance opening 412 allows the push portion to partially extend into the insertion cavity 411 of the conductive socket 41, shortening the distance between the push portion and the plug 201 (the plug 201 can directly compress the push portion when inserted into the insertion cavity 411), thereby reducing the overall volume of the linkage drive assembly 30. The conductive socket 41 is fixed to the base 21 via the fixing portion 212 (e.g., by bolts, snaps, etc.), preventing displacement of the conductive socket 41 due to forces (e.g., the impact of the plug 201 when inserted), ensuring that it is always aligned with the avoidance opening 412 of the push portion, and improving the reliability of the drive operation. Specifically, in this embodiment, the fixing portion 212 is a fixing groove 214a. After the push portion partially extends into the insertion cavity 411, the plug 201 can immediately contact the push portion when inserted (without any additional idle travel). This shortens the response time of the plug 201 insertion into the push portion and ensures the timely sealing action of the sealing sleeve 221a on the plug 201.

[0077] Reference Figure 9 Specifically, the base 21 is provided with a mounting groove 213, and the trigger member 23 is movably disposed within the mounting groove 213. The first connecting seat 322 and the second connecting seat 332 correspond to the avoidance groove 332a provided on the trigger member 23. Along the movement path of the first connecting seat 322 and the second connecting seat 332, the end of the trigger member 23 is placed within the mounting groove 213. The trigger member 23 is constrained in its range of motion by the base 21 through the mounting groove 213. At the same time, the connecting seat is prevented from interfering with the trigger member 23 through the avoidance groove 332a, ensuring that the trigger member 23 remains within the mounting groove 213 when the connecting seat moves. At the same time, the trigger member 23 and the mounting groove 213 can also form a guiding fit, constraining the movement path of the first connecting seat 322 and the second connecting seat 332.

[0078] Reference Figure 5 and Figure 6 The avoidance groove 332a of the connecting base (first connecting base 322 and second connecting base 332) provides space for the trigger 23 to move. When the connecting base moves along the intersecting path, the end of the trigger 23 is always constrained by the mounting groove 213, preventing the trigger 23 from being misaligned or stuck due to the connecting base's movement. This ensures that the trigger 23 only compresses the conductive spring 42 when needed (when the plug 200 is inserted into the second position). Furthermore, the mounting groove 213 limits the range of motion of the trigger 23, preventing the trigger 23 from being unable to accurately compress the conductive spring 42 due to lateral displacement, thereby ensuring reliable electrical connection between the conductive spring 42 and the fixed contact 43. The trigger 23 is integrated into the base 21 via the mounting groove 213. The connecting base is arranged crosswise with the trigger 23 via the avoidance groove 332a, reducing the lateral space occupied by the linkage drive assembly 30 and the trigger 23, resulting in a compact structure and facilitating miniaturization of the socket 100.

[0079] Reference Figure 4Furthermore, in order to improve the sealing effect of the sealing sleeve 221a, a sealing gasket 221b is provided at the end of the sealing sleeve 221a, and the sealing gasket 221b is sealed against the edge of the socket 11 under normal conditions. An independent sealing gasket 221b is added to the end of the sealing sleeve 221a, and the sealing effect is enhanced by the elastic or flexible material of the sealing gasket 221b, so as to avoid the sealing being poor due to rigidity or surface unevenness of the sealing sleeve 221a itself. The sealing gasket 221b is usually made of elastic or flexible material (such as silicone or rubber), and its surface can adapt to the slight unevenness of the edge of the socket 11 (such as burrs and scratches), filling the gap between the sealing sleeve 221a and the socket 11, preventing liquid (such as water and dust) from penetrating into the interior of the housing 10 through the gap, and ensuring the sealing effect under normal conditions. Moreover, the sealing sleeve 221b is an independent component and can be replaced separately (for example, after aging, only the sealing sleeve 221b needs to be replaced instead of the entire sealing sleeve 221a), which reduces maintenance costs; at the same time, the flexible material of the sealing sleeve 221b can absorb the impact force when the plug 200 is inserted, reduce the wear on the end of the sealing sleeve 221a, and extend the service life of the sealing structure.

[0080] Reference Figure 1 、 Figure 2 and Figure 9 Furthermore, the socket 100 further includes a ground electrode insert 50, and the housing 10 further includes a ground electrode opening 13. The drainage channel 211 includes ground electrode water passages 211a provided on both sides of the base 21. The ground electrode insert 50 is provided at the bottom of the base 21 and passes through the ground electrode opening 13 of the housing 10 through the ground electrode water passages 211a on both sides. The ground electrode insert 50 passes through the ground electrode opening 13 of the housing 10 through the ground electrode water passages 211a on both sides of the base 21. The ground electrode water passages 211a also serve as part of the drainage system. The drainage channel 211 further includes a socket water passage 211b corresponding to the socket 11. The ground electrode insert 50 is snap-fitted with the plug 200, which not only achieves an electrical connection, but also ensures the stability of the plug 200 after insertion and prevents water residue from entering the ground electrode area. Ground electrode water passages 211a are located on either side of the base 21, coinciding with the path through which the ground electrode insert 50 exits. When water enters the ground electrode opening 13 (e.g., rainwater flows along the ground electrode insert 50), the water flows directly through the drainage channels 211 on either side and is discharged directly through the drain opening 12 of the housing 10. This prevents water accumulation in the ground electrode area (which could cause oxidation or short-circuiting of the ground electrode insert 50), thereby improving the ground electrode's electrical conductivity. Furthermore, the ground electrode insert 50 exits from the bottom of the base 21 and is integrated into the drainage system through the drainage channels 211 on either side. This avoids spatial conflicts between the ground electrode insert 50 and other conductive components 40 (e.g., the conductive socket 41 and the conductive spring 42), reducing the overall size of the socket 100 and meeting the requirements of a miniaturized design.

[0081] Furthermore, an elastic reset member 60 is provided between the housing 10 and the lifting plate 22. The elastic reset member 60 is used to drive the lifting plate 22 to reset when the plug 200 is detached. The elastic reset member 60 (such as a spring or a shrapnel) provides a driving force for automatic reset of the lifting plate 22, so that the end of the sealing sleeve 221a abuts the edge of the socket 11 under normal conditions, thereby preventing the lifting plate 22 from being unable to reset in time due to friction or insufficient gravity after the plug 200 is unplugged. The elastic reset member 60 (such as a compression spring) is compressed and stores energy when the plug 200 is inserted. After the plug 200 is unplugged, the elastic force is released to drive the lifting plate 22 back, ensuring that the sealing sleeve 221a is reset in time and abuts the edge of the socket 11 (without relying on gravity or manual operation), thereby avoiding normal sealing failure problems caused by the lifting plate 22 getting stuck (such as the socket 11 being exposed and liquid seeping in when not reset).

[0082] Reference Figure 1 、 Figure 2 and Figure 10 、 Figure 11 Specifically, the shell 10 is composed of an upper cover 101 and a lower shell 102, and the upper cover 101 is concave to form a socket groove 101a, the drain outlet 12 is provided on the lower shell 102, and the socket 11 is located at the bottom of the socket groove 101a. The upper cover 101 is concave to form the socket groove 101a (that is, the "front" area of ​​the socket 100, for accommodating the plug 200 to be inserted), and the socket 11 is provided at the bottom of the groove (for the plug 201 to pass through); the lower shell 102 is buckled with the upper cover 101 (fixed by buckles, bolts, etc.) to form a closed space of the shell 10 (accommodating internal structures such as the seat body assembly 20), and the lower shell 102 is provided with a drain outlet 12 (connecting the internal and external environment). The socket 11 is located at the bottom of the socket slot 101a (i.e., the bottom of the groove formed by the indentation of the upper cover 101), not on the surface of the upper cover 101. A drain port 12 is provided in the lower shell 102 (typically at the bottom or side of the lower shell 102) and connects to the internal drainage channel 211 of the housing 10 to drain water that enters the interior of the housing 10 through the socket 11 and the ground electrode port 13. The drain port 12 is located in the lower shell 102 (typically at the lowest point of the housing 10). Once connected to the internal drainage channel 211, liquid (such as water that has seeped into the housing 10) can naturally flow toward the drain port 12 due to gravity, eliminating the need for additional power (such as a pump). The snap-fitting structure (e.g., snap connection, bolt fastening) between the upper cover 101 and the lower shell 102 simplifies the assembly process of the housing 10: the upper cover 101 forms the socket slot 101a and positions the socket 11, while the lower shell 102 houses the internal components and provides the drain port 12. The two simply snap together to seal the housing 10.

[0083] Combine Figure 3Furthermore, the snap-fit ​​interface (i.e., the contact surface between the upper cover 101 and the lower shell 102) can be further strengthened with auxiliary sealing structures such as a sealing ring 70 and sealant to prevent liquid from seeping into the interior of the housing 10 through the joints. Because the drain port 12 is located in the lower shell 102 (not the snap-fit ​​interface), the primary path for liquid intrusion is concentrated within the groove of the socket slot 101a (protected by the sealing sleeve 221a and sealing gasket 221b). The sealing performance of the snap-fit ​​interface only needs to withstand external splashes or small amounts of liquid, reducing the sealing requirements of the snap-fit ​​structure and improving the overall waterproof reliability of the housing 10. The addition of a sealing ring 70 to the snap-fit ​​interface (i.e., the contact surface between the upper cover 101 and the lower shell 102) allows the elastic deformation of the sealing ring 70 to fill the assembly gap between the upper cover 101 and the lower shell 102, thereby strengthening the overall sealing performance of the housing 10. This prevents liquids (such as water and dust) from seeping into the interior of the housing 10 through the joints. Even if the socket 100 is exposed to rain or a humid environment, the internal conductive components 40 (such as the conductive socket 41 and the fixed contact 43) and the driving components (such as the linkage driving member) can still remain dry, avoiding the risk of short circuit or corrosion.

[0084] Reference Figure 8 and Figure 9 Specifically, a sealing gasket 90 is provided between the drainage channel 211 and the lower shell 102. The sealing gasket 90 is added at the connection interface between the drainage channel 211 and the lower shell 102 (e.g., the connection between the outlet of the drainage channel 211 and the drain port 12 of the lower shell 102). The flexible material of the sealing gasket 90 fills the assembly gap between the channel and the shell 10, preventing liquid from seeping into the interior of the shell 10 from the connection during the drainage process. The sealing gasket 90 (e.g., a rubber gasket or waterproof rubber gasket) fills the assembly gap between the drainage channel 211 and the drain port 12 of the lower shell 102, preventing liquid from seeping into the interior of the shell 10 from the connection during the drainage process (e.g., water in the drainage channel 211 leaks back due to pressure fluctuations). As an independent component, the sealing gasket 90 can be replaced separately when the drainage channel 211 becomes clogged or aged (without disassembling the entire drainage system), reducing maintenance costs. Furthermore, the flexible material of the sealing gasket 90 buffers the assembly stress between the drainage channel 211 and the lower shell 102, preventing cracking of the channel due to rigid contact.

[0085] Reference Figure 3 Specifically, the fixed contact 43 is provided on the lower housing 102. The fixed contact 43 (the component that cooperates with the conductive spring 42 to achieve electrical conduction) in the conductive assembly 40 is mounted on the lower housing 102. The large interior space of the lower housing 102 facilitates the positioning and installation of the fixed contact 43 (e.g., by bolts or snap-in slots), reducing assembly difficulty. Furthermore, the fixed contact 43 and the conductive circuits (e.g., wires and terminals) of the lower housing 102 can be integrated into the layout, shortening the conductive path, reducing resistance loss, and improving conductive efficiency.

[0086] Combine Figure 8 and Figure 9 Furthermore, the base 21 is composed of a seat body 214 and a support seat 215, and the drainage channel 211 is protruded from the support seat 215 and inserted into the plug-in slot 102a of the lower shell 102. The base 21 is divided into the seat body 214 and the support seat 215: the seat body 214 is responsible for carrying the conductive component 40 (such as the conductive socket 41, the fixed contact 43) and the linkage drive component 30 (such as the pushing part, the connecting seat); the support seat 215 is connected to the seat body 214 (such as clamping, bolt fixing), mainly forming the drainage channel 211, and the drainage channel 211 protrudes toward the lower shell 102 (that is, extending downward from the bottom of the support seat 215). The drainage channel 211 protrudes from the support base 215 (i.e., the drainage channel 211 is part of the support base 215 or is fixed to the support base 215) and extends toward the lower shell 102. The lower shell 102 is provided with a plug-in slot 102a (such as a groove or a hole) that matches the shape of the drainage channel 211. The drainage channel 211 is inserted into the plug-in slot 102a to form a tight fit. The drainage channel 211 protrudes from the support base 215, and the lower shell 102 is provided with a corresponding plug-in slot 102a. The two are precisely positioned by snapping together. During assembly, the drainage channel 211 is simply aligned with the plug-in slot 102a of the lower shell 102 and inserted to complete the connection between the drainage channel 211 and the lower shell 102. After the drainage channel 211 is inserted into the insertion slot 102a, the contact surfaces (e.g., cylindrical or square) can be further sealed by an interference fit or the addition of a sealant (e.g., silicone) to prevent liquid from seeping into the interior of the housing 10 from the connection between the drainage channel 211 and the lower shell 102. Furthermore, the structural rigidity of the support base 215 (typically made of plastic or metal) supports the shape of the drainage channel 211, preventing deformation of the drainage channel 211 due to forces (e.g., liquid pressure, assembly stress), thereby ensuring a durable seal. If the drainage channel 211 becomes clogged or damaged, only the support base 215 (rather than the entire base 21) needs to be removed to replace or clean the drainage channel 211, reducing maintenance costs. Furthermore, the separate design of the base body 214 and support base 215 facilitates modular production (e.g., the base body 214 and support base 215 can be injection molded separately), reducing mold complexity and manufacturing costs.

[0087] Combine Figure 8 and Figure 9Furthermore, a waterproof gasket 80 is provided between the base body 214 and the support base 215. This gasket 80 includes an elastic sealing sleeve 81 corresponding to the trigger 23. The trigger 23 compresses the conductive spring 42 into contact with the fixed contact 43 through the elastic sealing sleeve 81. The waterproof gasket 80 is added to the interface (i.e., the contact surface) between the base body 214 and the support base 215 of the base 21. The gasket includes an elastic sealing sleeve 81 for the trigger 23. The elastic sealing sleeve 81 encases the trigger 23. When the trigger 23 is actuated (e.g., when the plug 200 is inserted, the trigger 23 moves), the deformation of the elastic sealing sleeve 81 compresses the conductive spring 42, forcing it into contact with the fixed contact 43, completing the circuit. The waterproof gasket 80 (typically made of rubber or silicone) fills the gap between the base body 214 and the support base 215, preventing liquids (such as water and dust) from seeping into the housing 10 through the joints between the separate structures of the base 21. An elastic sealing sleeve 81 (e.g., a silicone sleeve) encases the trigger 23. When the trigger 23 moves (e.g., when the plug 200 is inserted, driving the trigger 23 downward or laterally), the elastic sealing sleeve 81 deforms with the trigger 23 and maintains a tight seal around the trigger 23, preventing liquid from seeping along the path of the trigger 23. The deformation of the elastic sealing sleeve 81 compensates for assembly errors (e.g., positional offset) between the trigger 23 and the conductive spring 42, ensuring reliable contact between the conductive spring 42 and the fixed contact 43 (conducting the circuit).

[0088] Reference Figure 3 Furthermore, the base body 214 is provided with a fixing slot 214a, in which the conductive socket 41 is located. The conductive socket 41 includes a socket 41a that receives the cavity 411 and a pin 41b that connects to the socket 41a. The support base 215 is further provided with a clearance slot 215a, through which the pin 41b passes to connect with the conductive spring 42. The fixing slot 214a on the base body 214 secures the conductive socket 41 (the socket 41a portion), and the clearance slot 215a guides the pin 41b (conductive pin) of the conductive socket 41 to connect with the conductive spring 42.

[0089] The fixing slot 214a (e.g., a groove or slot that matches the shape of the conductive socket 41) limits the lateral and longitudinal displacement of the conductive socket 41, preventing the conductive socket 41 from loosening or tilting due to the impact force when the plug 200 is inserted (e.g., when the pin 201 is inserted into the socket). Loosening may cause the pin 201 to be inserted incorrectly or the socket 41a to have poor contact with the conductive spring 42. The clearance slot 215a (e.g., a through-hole or groove) provides a clear guide path for the pin 41b of the conductive socket 41 (the metal pin for connecting to the conductive spring 42), preventing the pin 41b from bending or breaking due to free swing (a breakage of the pin 41b would directly interrupt the conduction). Furthermore, the limiting effect of the clearance slot 215a ensures that the contact position between the pin 41b and the conductive spring 42 is precise (e.g., the end of the pin 41b is aligned with the contact point of the conductive spring 42), thereby improving conductivity efficiency.

[0090] Specifically, the conductive spring 42 has a slot that fits over the pin 41b, which is inserted into the slot. A rubber ring is also provided between the conductive spring 42 and the base body 214. The pin 41b is inserted into the rubber ring and then into the slot, preventing water from flowing from the conductive socket 41 into the drainage channel 211 and seeping there. The design of the fixing slot 214a and the clearance slot 215a standardizes the installation process of the conductive socket 41 (simply inserting the socket 41a into the fixing slot 214a and the pin 41b into the clearance slot 215a), reducing the difficulty of manual assembly.
