Description

Technical Field

[0001] This invention relates to the field of connectors, and more particularly to a waterproof, dustproof, and shockproof electrical connector socket and its electrical connector. Background Technology

[0002] As a basic terminal device for electrical connection, sockets are widely used in various power consumption scenarios such as homes, industries, and outdoors. Their safety and protection performance are directly related to personal and property safety and stable equipment operation.

[0003] With the formal implementation of my country's mandatory national standards and the simultaneous promotion of new national standards, the protection level and safety requirements of plug and socket products have been significantly improved. The new national standard specifically adds a category for outdoor-specific power strips, explicitly requiring these products to have waterproof, crush-resistant, vibration-resistant, and overcharge protection functions. This regulatory upgrade elevates household sockets from "basic electrical accessories" to electrical safety devices with both intelligent protection and higher protection standards, fully reflecting the market and industry's increasingly urgent demand for waterproof and dustproof performance in socket products.

[0004] In existing technologies, solutions for waterproofing and dustproofing sockets can be mainly divided into the following categories:

[0005] The first type is the socket structure with an independent waterproof cover or protective cover. This type of solution has a flip cover, protective cover or waterproof cover on the outside of the socket body. The physical shielding of the socket area is achieved by closing the cover. However, this type of solution requires the user to manually close the waterproof cover or protective cover after each plugging and unplugging to achieve protection, which is inconvenient. If the user forgets to close the cover, the socket is completely exposed, and the waterproof and dustproof effect is completely lost.

[0006] The second type uses elastic sealing materials to flexibly seal the socket. This method involves placing an elastic waterproof gasket on the inner surface of the socket housing, with a sealing hole at the corresponding socket location. The gasket automatically seals itself by elastic deformation. When the plug is inserted, the prongs open the gasket; after removal, the rubber's elasticity re-seals the socket. This method overcomes the manual operation required by the first type, achieving automatic switching of the sealing state during insertion and removal, offering greater convenience. However, the flexible elastic material is prone to permanent deformation during repeated insertion and removal, and its sealing performance gradually diminishes with increased use, limiting its lifespan.

[0007] The third type is the socket structure using a safety door or baffle mechanism. This type of solution uses a sliding safety door or baffle inside the socket. When no plug is inserted, a spring returns the baffle to its original position, blocking the socket and preventing foreign objects and liquids from entering. For example, the patent for "Sealed Hole Safety Socket" (publication number 200620128273.5) uses a controllable door-shaped sliding plate with a return spring and a socket baffle to form a socket blocking mechanism. The protective baffle works in conjunction with the return spring; when no plug is inserted, the return spring pushes the protective baffle to the position blocking the socket. When the plug is inserted, it pushes the baffle to a different position. After the plug is removed, the baffle automatically returns to its original position, re-blocking the socket, due to spring force. While such solutions achieve self-shielding of the socket after plugging and unplugging, there is usually a gap between the baffle and the socket, making it difficult to achieve a complete seal. The water protection capability is limited, and its main function is to prevent children from accidentally touching it and to block larger foreign objects. In addition, multiple sockets require multiple sets of protective baffles and reset springs, making the structure cumbersome and complex, not simple and reasonable, and difficult to arrange in the narrow space of the socket.

[0008] Overall, existing waterproof and dustproof socket technologies still have significant shortcomings in sealing the insertion port after plugging and unplugging: external waterproof cover solutions rely on manual operation, which is inconvenient and prone to failure due to negligence; elastic material sealing solutions have a limited long-term service life; and safety door baffle solutions can only achieve mechanical blocking and are difficult to achieve a true seal, with a cumbersome and complex structure. Achieving simultaneous waterproof, dustproof, and electric shock protection functions, and actively, reliably, and persistently sealing the socket insertion port after the plug is removed without any additional user intervention, remains a pressing technical problem to be solved in this field. Summary of the Invention

[0009] The primary technical problem to be solved by this invention is to provide a waterproof, dustproof, and shockproof electrical connector socket, which has an active automatic waterproof structure to prevent consumers from forgetting to activate the waterproof device. It has the advantages of simple and reliable structure, good sealing effect, long service life, and convenience.

[0010] Another technical problem to be solved by the present invention is to provide a related electrical connector.

[0011] The technical solution of this invention to solve the primary technical problem is: a waterproof, dustproof, and shockproof electrical connector socket, comprising:

[0012] A plug is located at the front of the socket for inserting the power connector plug;

[0013] Multiple male fluid carriers are fixed inside the socket and are inserted into the female fluid carrier in the plug of the electrical connector to achieve electrical connection;

[0014] Its features are:

[0015] An insulating sealing cap is fixed to the head of the fluid carrier and becomes part of it to prevent contact with foreign objects.

[0016] An active sealing mechanism, disposed within the insertion port of the socket, includes:

[0017] An inner core component, the shape and size of which are adapted to the insertion port of the socket, has multiple male fluid holes distributed on its surface, allowing the male fluid to pass through the male fluid holes and move back and forth;

[0018] An elastic reset element is supported between the inner core assembly and the bottom surface of the insertion port, so that the inner core assembly maintains its outward movement tendency;

[0019] A limiting rod is connected to the inner core assembly and limits the movement of the inner core assembly within the insertion port of the socket;

[0020] At least one waterproof ring on the outer side of the inner core is fixed to the outer peripheral surface of the inner core assembly to achieve a sliding seal with the insertion port of the socket;

[0021] Multiple fluid-carrying sealing rings are lined in the inner wall of their respective male fluid-carrying holes to achieve a sliding sealing fit with the male fluid;

[0022] When the plug is inserted into the socket, the active sealing mechanism inside the socket's insertion port can retract to make room for the plug to be inserted into the socket's insertion port, so that the female fluid inside the plug and the male fluid inside the socket can be connected to achieve electrical conduction. When the plug is removed from the socket, the active sealing mechanism inside the socket's insertion port can move outward to cooperate with the insulating sealing cap set on the head of the male fluid inside the socket, sealing the entire insertion port of the socket.

[0023] Furthermore, the inner core assembly includes an inner core front plate and an inner core rear plate, which are fixed together in a front-to-back manner. The inner core front plate and the inner core rear plate are provided with common fluid holes at corresponding positions to match the common fluid.

[0024] Furthermore, the rear end of the fluid-carrying hole of the inner core front plate is provided with a mounting slot, and a fluid-carrying sealing ring is fixed in the mounting slot to achieve a sealing and waterproof function.

[0025] Furthermore, an annular groove is provided between the inner core front plate and the inner core rear plate, and a waterproof ring on the outer side of the inner core is fixed in the annular groove to achieve a sealing and waterproof function.

[0026] Furthermore, the inner core component has a limiting hole at its rear center, and a limiting rod is inserted into the corresponding central opening of the socket. The limiting hole and the limiting rod are connected to achieve the limiting function for the inner core component.

[0027] Furthermore, the elastic reset element is a reset spring, which is sleeved on the limiting rod. One end of the reset spring is supported on the bottom surface of the socket insertion port, and the other end of the reset spring abuts against the inner core assembly. The reset spring always applies an outward force, so that the inner core assembly always maintains an outward tendency.

[0028] Furthermore, the inner core assembly adopts an integral inner core plate with a one-piece structure. A common fluid-carrying hole is provided at the corresponding position to match the common fluid. Correspondingly, an annular groove is provided on the outer periphery of the inner core plate to fix the waterproof ring on the outer side of the inner core, and an installation slot is provided in the middle of the common fluid-carrying hole to embed the fluid-carrying sealing ring.

[0029] Finally, the male fluid carrier is a metal cylinder with a reduced diameter at the front end connected to a fixed insulating sealing cap. The outer diameter of the insulating sealing cap is consistent with the outer diameter of the metal cylinder. The female fluid carrier is a metal cylinder with a hollow middle section and a hollow front section, and an axially arranged elastic groove. The inner diameter of the female fluid carrier matches the outer diameter of the male fluid carrier in the socket, so that they can be plugged into each other to achieve electrical connection.

[0030] The technical solution of the present invention to solve another technical problem is: an electrical connector, which includes a plug and a socket, wherein the front end of the plug is provided with a insertion portion that cooperates with the insertion port of the socket, and the plug is provided with a female fluid carrier; characterized in that the plug is any of the plugs described above.

[0031] Furthermore, the top of the plug is provided with a mounting positioning groove, and a clamp is provided in the mounting positioning groove. The bottom of the clamping end of the clamp is provided with a fixing block. Correspondingly, the front of the mounting positioning groove is provided with a through hole, and the top of the socket insertion port is provided with a fixing groove. The fixing block passes through the through hole and cooperates with the fixing groove to realize the insertion locking and fixation.

[0032] Finally, a spring hole is provided on the rear side of the mounting positioning groove, and a clamping spring is fixed in the spring hole. The other end of the clamping spring abuts against the pressing part of the clamp, and the clamping spring always applies an outward force to keep the clamp in a clamping state.

[0033] Compared with the prior art, the technical advantages of this application are as follows: When the plug is unplugged or not inserted, the active sealing mechanism will actively protect the internal fluid of the socket from water, dust and other foreign objects from entering the socket. Furthermore, the front end of the fluid carrier is narrowed and connected to a fixed insulating sealing cap, which cooperates with the fluid carrier hole on the inner core assembly, making it impossible for people to come into contact with the fluid carrier and preventing accidental electric shock. Moreover, multiple fluid carrier holes are distributed on the same inner core assembly, requiring only one reset spring, avoiding the drawbacks of multiple baffles and springs in traditional structures. The structure is simple, reliable, low-cost, and easy to assemble and produce. In addition, the limit rod prevents excessive movement of the inner core assembly and enhances its service life.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention patent based on the specific circumstances.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] See Figures 1 to 5 A waterproof electrical connector includes a plug 1 and a socket 4. The plug 1 has a insertion portion 2 at its front end and a female fluid carrier 3 inside. Correspondingly, the socket 4 has an insertion port 5 at its front end, the size and shape of which matches the insertion portion 2 of the plug 1, allowing the insertion portion 2 of the plug 1 to be inserted. The socket 4 has a male fluid carrier 6 inside. The improvement lies in the active sealing mechanism A within the insertion port 5 of the socket 4. When the plug 1 is inserted into the socket 4, the active sealing mechanism A within the insertion port 5 of the socket 4 can retract to create space, allowing the plug 1 to be inserted... When plug 1 is inserted into the insertion port of socket 4, the female fluid 3 in plug 1 and the male fluid 6 in socket 4 are connected to achieve electrical conduction. When plug 1 is removed from socket 4, the active sealing mechanism A in the insertion port 5 of socket 4 can move outward and cooperate with the insulating sealing cap 15 set on the head of the male fluid 6 in socket 4 to seal the entire insertion port of socket 4. This prevents water, dust or other foreign objects from entering the insertion port 5 of socket 4 and from touching the male fluid 6 in the insertion port 5 of socket 4, thus achieving a sealing and safety protection function.

[0044] The active sealing mechanism A includes an elastically retractable inner core assembly 7. When the plug portion 2 of the plug 1 pushes the inner core assembly 7 backward, the male fluid 6 inside the socket 4 is exposed, allowing it to be plugged into and connected with the female fluid 3.

[0045] The inner core assembly 7 includes a front inner core plate 8 and a rear inner core plate 9, which are fixed together. The front and rear inner core plates 8 and 9 have multiple fluid-carrying holes 10 at corresponding positions, which match multiple fluid-carrying holes 6. This allows the fluid-carrying holes 6 to be exposed as the front and rear inner core plates 8 and 9 move backward. In this embodiment, three fluid-carrying holes 6 are used. The rear end of the fluid-carrying hole 10 on the front inner core plate 8 has a mounting slot 11, the diameter of which is typically larger than the diameter of the fluid-carrying hole 6. A fluid-carrying sealing ring 12 is fixed in the mounting slot 11, cooperating with the fluid-carrying hole 6 to achieve a sealing and waterproof function. An insulating sealing cap 15 is fixed to the front end of the fluid-carrying hole 6 to prevent accidental electric shock. An annular groove 25 is provided on the outer circumferential surface between the inner core front plate 8 and the inner core rear plate 9. An outer waterproof ring 26 of the inner core is fixed in the annular groove 25, which slides and seals with the insertion port of the socket 4 to achieve a waterproof sealing function.

[0046] Of course, to facilitate production and simplify assembly, the inner core front plate 8 and inner core rear plate 9 can be made into an integrated structure to form an integral inner core plate. Correspondingly, an annular groove 25 is provided on the outer periphery of the inner core plate to embed and fix the outer waterproof ring 26 of the inner core. A mounting slot 11 is provided in the middle of the fluid-carrying hole 10 to embed the fluid-carrying sealing ring 12, which can also achieve a similar effect.

[0047] The inner core assembly 7 has a limiting hole 13 at its rear center. A limiting rod 14 is inserted into the corresponding central opening of the socket 4. The limiting rod 14 has a horizontal "T" shape in cross-section and an enlarged end at its rear. The limiting hole 13 is connected to the front end of the limiting rod 14. This connection can be made by threaded connection. This can prevent the inner core assembly 7 from moving too much and achieve the limiting function. At the extreme position, the insulating sealing cap 15 set on the head of the male fluid 6 can be hidden in the male fluid hole 10 and cooperate with the fluid sealing ring 12 to seal, thereby sealing the entire insertion port of the socket 4.

[0048] A reset spring 16 is fixed inside the socket 4. The reset spring 16 is sleeved on the limit rod 14. One end of the reset spring 16 is supported on the bottom surface of the insertion port of the socket 4, and the other end of the reset spring 16 is in contact with the inner core assembly 7. The reset spring 16 always applies an outward force, so that the inner core assembly 7 always maintains an outward tendency, thereby realizing the reset function.

[0049] In addition, the fluid-carrying body 6 inside the socket 4 is made of metal cylinder. After the front end is reduced in diameter, the insulating sealing cap 15 is fixed by threaded connection, making it part of the fluid-carrying body 6 to prevent contact with foreign objects. The outer diameter of the insulating sealing cap 15 is consistent with the outer diameter of the metal cylinder, so as to obtain a smooth surface transition. At the rear end of the metal cylinder is the wiring terminal, which is used to connect the wiring.

[0050] The plug 1 has a mounting positioning groove 17 at its top, and a clamp 18 is installed in the mounting positioning groove 17. Pins 23 are located on both sides of the bottom of the clamp 18, and corresponding shaft holes 24 are located on both sides of the mounting positioning groove 17. The clamp 18 is rotatably fixed to the mounting positioning groove 17 through the connection and engagement between the pins 23 and the shaft holes 24. A fixing block 19 is located at the bottom of the clamping end of the clamp 18. Correspondingly, a through hole is located at the front of the mounting positioning groove 17, and a fixing groove 20 is located at the top of the insertion port 5 of the socket 4. The fixing block 19 and the fixing groove 20 are interlocked to achieve the mutual locking function of the plug 1 and the socket 4. A spring hole 21 is located on the rear side of the mounting positioning groove 17 at the top of the plug 1. A clamping spring 22 is fixed in the spring hole 21. The upper end of the clamping spring 22 abuts against the pressing part of the clamp 18, and the clamping spring 22 always applies an outward force to keep the clamp 18 in a clamped state.

[0051] In addition, the female fluid 3 inside the socket 4 is a metal cylinder with a hollow middle section and front section, and an axially arranged elastic groove 27. The inner diameter of the female fluid 3 matches the outer diameter of the male fluid 6 inside the socket 4, so that the female fluid 3 and the male fluid 6 can be plugged in and achieve electrical connection.

[0052] When the user uses the connector of this application for connection, press the clamp 18 with a finger, align the plug 2 of the plug 1 with the insertion port 5 of the socket 4 and insert it. When the outer shell of the plug 2 abuts against the inner core assembly 7, the inner core assembly 7 will overcome the elastic force of the return spring 16 and move backward. After a certain stroke, the male fluid 6 will pass through the fluid sealing ring 12 and be exposed from the male fluid hole 10 of the inner core assembly 7. Then the male fluid 6 in the socket 4 and the female fluid 3 in the plug 2 will be connected to each other to realize the circuit connection. Then the user releases the clamp 18 with a finger and the fixing block 19 at its bottom and the positioning groove 17 on the socket 4 will be connected to each other to realize the locking.

[0053] When the user wants to disconnect the connector, they only need to press the clamp 18 with their finger to unlock the fixing block 19 at its bottom and the positioning groove 17 on the socket 4, and pull the plug 1 out of the socket 4. The inner core assembly 7 will move forward under the action of the return spring 16. When the inner core assembly 7 reaches the preset position, the limit rod 14 will restrict the inner core assembly 7 from moving outward. At this time, the front end of the male fluid 6 of the socket 4 will re-enter the male fluid hole 10 of the inner core assembly 7. The mounting slot 11 of the inner core assembly 7 has a fluid-carrying sealing ring 12, which cooperates with the insulating sealing cap 15 at the end of the male fluid 6 to seal. The inner core assembly 7 has an inner core outer waterproof ring 26 fixed in the annular groove 25, which seals with the insertion port of the socket 4 to seal the entire insertion port 5 of the socket 4, realizing the functions of waterproof, dustproof and electric shock prevention.
