Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a modular quick-plug waterproof electrical connector. Background Technology

[0002] Electrical connectors, as key components for transmitting electrical signals or power, are widely used in complex environments such as ships, automobiles, communications, medical equipment, and outdoor power supply units. In these applications, connectors are often exposed to direct contact with external liquids such as rain, splashes, or water accumulation, making waterproofing one of the core technical requirements for the safe and reliable operation of connectors.

[0003] Most existing waterproof electrical connectors employ a structure where the seal is formed after the connection is complete. For example, this can be achieved by using an O-ring between the plug and socket for engagement and then pressing to seal, or by using a threaded locking ring or a pressure cap structure to increase the contact pressure at the mating surfaces.

[0004] While these measures can achieve a high level of protection to some extent, they still cannot prevent external water from entering before connection. If there is rainwater or splashed liquid residue on the end face of the plug or socket before the insertion is performed, this liquid can easily be brought into the contact area during the insertion process, causing short circuits, breakdowns, or corrosion problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a modular, quick-plug waterproof electrical connector, aiming to alleviate the aforementioned problems to at least some extent.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A modular, quick-plug waterproof electrical connector includes a connector housing with a sliding sleeve, an interface cavity within the connector housing, a plug body within the interface cavity, and the plug body being connected to a cable attached to the connector housing. The connector also includes:

[0008] An annular airbag is located within the interface cavity near the outer opening of the connector housing.

[0009] A control component located within the connector housing is used to inflate and deflate the annular airbag when the sliding sleeve slides.

[0010] The plug body is provided with a rotating shaft, which is rotatably connected to the interface cavity, so that the plug body can rotate around the rotating shaft between facing inward and outward.

[0011] A rotating component located within the connector housing is used to rotate the plug body when the sliding sleeve slides.

[0012] Preferably, when the sliding sleeve moves a predetermined distance a along the connector housing, the control component releases the gas in the annular airbag, and the rotating component rotates the plug body by a predetermined angle;

[0013] When the sliding sleeve moves a predetermined distance b along the connector housing, the control component inflates within the annular airbag.

[0014] Preferably, the sliding sleeve has a connection opening, the connection opening has a card interface, the connector housing is connected to a connecting rod, and the connecting rod is connected to a card contact piece adapted to the card interface.

[0015] Preferably, the rotating component includes a helical opening on the rotating shaft, a straight section opening at the end of the helical opening, a sliding groove on one side of the interface cavity, a guide rod slidably connected in the sliding groove, the guide rod being inserted into the straight section opening, and a spring a connecting the guide rod and the sliding groove.

[0016] Preferably, the rotating component further includes a connecting rod connected to the sliding sleeve, the connecting rod extending into the interior of the connector housing and fixed with a connecting frame, a guide rail connected to the connecting frame, and a guide post cooperating with the guide rail at one end of the guide rod.

[0017] Preferably, the control component includes a connecting cavity formed on the connector housing, a connecting pipe connected to the connecting cavity and the annular airbag, a connecting pipe also connected to the connecting cavity, an air control cavity provided inside the connector housing, the connecting pipe connected to the air control cavity, a piston provided inside the air control cavity, and a spring b connected between the piston and the air control cavity.

[0018] Preferably, a connecting strip is slidably connected to the gas control chamber, the connecting strip has a boss, the piston is fixed to the connecting strip, and the connecting strip passes through the interior of the connecting frame.

[0019] Preferably, a spring c is connected between the connecting frame and the connector housing.

[0020] In summary, the present invention has the following main beneficial effects:

[0021] This invention achieves dual protection for the electrical connector in its non-operating state and dynamic sealing switching during connection and disconnection by controlling the rotation of the plug body and the inflation and deflation of the annular airbag through a sliding sleeve linkage. This significantly improves the connector's protection capabilities in complex environments. When not in use, the plug body retracts and the annular airbag inflates to form a three-dimensional sealing structure, preventing rainwater and splashing liquids from entering the contact end. During connection, the sliding sleeve's forward movement sequentially triggers the deflation, rotation, and re-inflation process, automatically rotating the plug out and mating with the external connector, resulting in highly efficient operation.

[0022] When disconnecting, the seal is restored synchronously in the reverse direction, enabling plug retraction and interface sealing, ensuring long-term protection in idle states. This invention features convenient operation, strong structural linkage, and high protection level, making it particularly suitable for electrical connection applications in harsh environments such as ships, outdoor power supplies, and emergency communications.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This embodiment provides a modular, quick-plug waterproof electrical connector, such as... Figures 1-7 As shown, it includes a connector housing 100, a sliding sleeve 101, an interface cavity 102, a plug body 103, an annular airbag 105, a control component, and a rotating component.

[0038] Specifically, the connector housing 100 has a hollow structure, and the sliding sleeve 101 is disposed on the outside of the connector housing 100, which can slide along the axial direction of the connector housing 100. The interface cavity 102 is opened inside the connector housing 100 to accommodate the plug body 103. The plug body 103 is electrically connected to the cable on the connector housing 100. The plug body 103 is provided with a rotating shaft 104, which is rotatably connected to the interface cavity 102, so that the plug body 103 can rotate around the rotating shaft 104 between inward and outward.

[0039] To achieve plug protection and waterproofing before connection, an annular airbag 105 is provided inside the interface cavity 102 at an opening near the outer side of the connector housing 100. This annular airbag 105 remains inflated when not in use, forming a sealed protection. The connector housing 100 also includes a control component for controlling the inflation and deflation of the annular airbag 105 according to the sliding stroke of the sliding sleeve 101, thereby switching the expansion and contraction of the annular airbag 105. A rotating component is also located inside the connector housing 100, cooperating with the rotating shaft 104 of the plug body 103, driving the plug body 103 to rotate when the sliding sleeve 101 slides.

[0040] In actual use, the user pushes the sliding sleeve 101 along the connector housing 100. When the sliding sleeve 101 moves to a predetermined distance a, the control component initiates a deflation operation, causing the annular airbag 105 to contract from its inflated state, reserving space for the plug to rotate. At the same time, the rotating component starts working, driving the plug body 103 to rotate around the pivot 104 to an outward-facing position, completing the plug's rotation out action. Continuing to push the sliding sleeve 101, when it slides to a predetermined distance b, the control component restarts, inflating the annular airbag 105 to restore its inflated state, fitting snugly against the insertion area and enhancing waterproof sealing.

[0041] The modular quick-plug waterproof electrical connector provided by this invention is key to achieving automatic rotation of the plug body 103 and inflation / deflation of the annular airbag 105 through the moving drive control component and rotating component of the sliding sleeve 101, thereby forming dynamic protection before and after connection, significantly improving the waterproof performance and ease of operation of the electrical connector under complex working conditions.

[0042] In the non-operating state, the sliding sleeve 101 is in the initial position of the connector housing 100. At this time, the plug body 103 is oriented towards the interior of the interface cavity 102 via the pivot 104, and the front contact area is retracted, forming the first sealing barrier. The annular airbag 105 is in an inflated state, closely attached to the interface cavity 102 and the plug body 103, effectively preventing rainwater, accumulated water, or splashing liquid from entering, forming the second sealing barrier, significantly improving the connector's environmental adaptability and protection level in the non-use state.

[0043] When the user is ready to perform a connection operation, they can manually push the sleeve 101 or allow another electrical connector to touch the sliding sleeve 101 during mating. The sliding sleeve 101 slides axially along the connector housing 100. As the sliding sleeve 101 moves a predetermined distance 'a', the control component inside the connector responds first, performing a deflation operation, causing the annular airbag 105 to contract rapidly. This action releases the closed state of the interface cavity 102 opening, reserving operating space for subsequent plug rotation and avoiding structural interference or jamming caused by the expansion of the annular airbag 105, thereby ensuring smooth plug operation and sensitive mechanical response.

[0044] Subsequently, the rotating component is driven in conjunction with the sliding sleeve 101 reaching distance 'a', causing the plug body 103 to rotate around the pivot 104, changing from an inward-facing orientation to an outward-facing orientation. The plug end actively flips over, exposing the interface area, ready to connect with the external electrical connector. This design eliminates the need for manual plug flipping, making the plug connection process more automated and precise, significantly improving ease of use, and is particularly suitable for blind-plugging or rapid connection scenarios in harsh environments.

[0045] As the sliding sleeve 101 continues to slide, when it reaches a predetermined distance b, the control component is triggered again, and begins to inflate the annular airbag 105. At this time, the annular airbag 105 expands and fits against the area around the plug and interface joint, sealing the plug body 103 area again after the plug has been fully inserted, thereby enhancing the sealing integrity and electrical safety of the insertion interface.

[0046] During the disconnection process, the sliding sleeve 101 slides in the opposite direction along the connector housing 100, which also triggers the control component and the rotating component to complete the reverse operation. First, when the sliding sleeve 101 returns to the predetermined distance a, the control component controls the annular airbag 105 to deflate and contract, and the rotating component then rotates the plug body 103 back to the inward position to prevent the plug from being exposed; when it continues to return to the predetermined distance b, the control component inflates the annular airbag 105 again, and the annular airbag 105 resumes its expansion, sealing the interface area at the end of the plug and re-establishing the protective barrier in the non-use state.

[0047] In this embodiment, a connection opening 200 is provided on the side wall of the sliding sleeve 101, and a card interface 201 for structural positioning is provided in the connection opening 200.

[0048] The connector housing 100 is provided with a connecting rod 202, which is inserted into the connecting opening 200 of the sliding sleeve 101, and a snap-fit ​​piece 203 is connected to one side of it. The size and geometry of the snap-fit ​​piece 203 match the snap-fit ​​interface 201, so that stable snap-fit ​​positioning can be achieved during the sliding of the sliding sleeve 101.

[0049] With the above configuration, a connection opening 200 is provided on the external structure of the sliding sleeve 101, and a card interface 201 is integrated inside the connection opening 200. Simultaneously, a connecting rod 202 and a snap-fit ​​piece 203 that mates with the card interface 201 are provided on the connector housing 100, forming a mechanical interlock between the sliding sleeve 101 and the connector housing 100. After the connection operation is completed, the sliding sleeve 101 continues to slide to the predetermined position b, and the control component controls the annular airbag 105 to re-inflate and seal. At this time, the termination position of the sliding sleeve 101 is maintained by the snap-fit ​​piece 203 snapping back into the corresponding card interface 201, preventing structural loosening due to vibration or pulling after connection, and further enhancing the mechanical safety in the completed connection state.

[0050] In this embodiment, the rotating component includes a spiral opening 300 disposed on the surface of the rotating shaft 104 of the plug body 103. The spiral opening 300 extends spirally along the axial direction of the rotating shaft 104, and its first end has a straight section opening 301 with a straight section structure. A corresponding groove 302 is provided in the interface cavity 102, and a guide rod 303 is slidably connected in the groove 302. The front end of the guide rod 303 is inserted into the straight section opening 301 of the rotating shaft 104, allowing it to move up and down within the groove 302. In addition, a spring a304 is provided between the guide rod 303 and the inner wall of the groove 302 to apply a restoring force to the guide rod 303.

[0051] With the above settings, during use, the user pushes the sliding sleeve 101 to slide along the axial direction of the connector housing 100. As the sliding sleeve 101 moves, the guide rod 303 slides along the sliding groove 302. During the sliding of the guide rod 303, its front end will first slide in the straight section 301. During this process, the annular airbag 105 is in a deflated state, and the front end area of ​​the interface cavity 102 is in an unsealed state, reserving space for the subsequent rotation of the plug body 103 and preventing the airbag structure from hindering the rotation.

[0052] As the sliding sleeve 101 continues to slide, the guide rod 303 enters the spiral opening 300 on the rotating shaft 104 from the straight section opening 301. The rotating shaft 104 is forced to rotate circumferentially along the spiral trajectory, thereby driving the plug body 103 to gradually turn from an inward state to an outward posture, completing the automatic adjustment of the plug docking direction.

[0053] In this embodiment, the rotating component further includes a connecting rod 305 disposed on the sliding sleeve 101. One end of the connecting rod 305 is connected to the sliding sleeve 101 and slides together with the sliding sleeve 101, while the other end extends into the interior of the connector housing 100 and a connecting bracket 306 is fixed at its end.

[0054] A guide rail 307 structure is fixedly installed on the connecting frame 306. The guide rail 307 has a bent structure and is composed of a first sliding section, a second inclined turning section, and a third sliding section that are connected to each other, forming an approximately "Z" shaped path. The first sliding section is set parallel to the sliding direction of the sliding sleeve 101 and is used to guide the linear sliding of the guide post 308; the second inclined turning section is set at an obtuse angle with the first sliding section and is used to guide the guide post 308 to undergo a directional transition; the third sliding section is again parallel to the first sliding section.

[0055] One end of the guide rod 303 is connected to a guide post 308, which is embedded in the guide rail 307 and can slide along a preset path in the guide rail 307.

[0056] With the above configuration, when the user pushes the sliding sleeve 101 to slide along the axial direction of the connector housing 100, the connecting rod 305 fixed on the sliding sleeve 101 moves synchronously and transmits the sliding action to the connecting frame 306 fixed at the end of the connecting rod 305. During the sliding process, the connecting frame 306 drives the guide rail 307 mounted on it to move as a whole, thereby driving the guide post 308 embedded in the guide rail 307 to slide along the trajectory of the guide rail 307. Since the guide post 308 is connected to the guide rod 303, the change in the path of the guide post 308 will directly guide the guide rod 303 to perform controlled movement.

[0057] The guide rail 307 has a bent "Z" shaped structure. Its first sliding section is parallel to the sliding direction of the sliding sleeve 101. The guide post 308 maintains linear sliding in this section, so that the guide rod 303 initially maintains stable advancement. When the guide post 308 enters the second inclined turning section, due to the change of the track angle, the movement direction of the guide post 308 deflects, guiding the guide rod 303 to generate a compound motion along a predetermined trajectory, gradually applying rotational torque to the rotating shaft 104. When the guide post 308 further enters the third sliding section, the movement direction returns to parallel, the guide rod 303 completes the entire deflection path, and finally causes the rotating shaft 104 to drive the plug body 103 to rotate from the inward state to the outward posture, ready to dock with the external electrical connector.

[0058] The first sliding section, the second tilting and turning section, and the third sliding section of the guide rail 307 correspond to the air release action, the plug rotation action, and the air filling and sealing action during the sliding process of the sliding sleeve 101, respectively, thereby realizing continuous linkage control under sliding drive.

[0059] In this embodiment, the control component includes a connecting cavity 400 formed on the connector housing 100, a connecting pipe 401 connected to the connecting cavity 400, and the connecting pipe 401 connected to the annular airbag 105 to establish a gas passage. A connecting pipe 402 is also connected to the connecting cavity 400, and the connecting pipe 402 is connected to a gas control chamber 403 disposed inside the connector housing 100. A piston 404 is disposed inside the gas control chamber 403, and a spring b405 is connected between the piston 404 and the inner wall of the gas control chamber 403 to provide a restoring force to the piston 404.

[0060] With the above configuration, when the user pushes the sliding sleeve 101 to move along the connector housing 100, the guide post 308 first enters the first sliding section and the second inclined turning section of the guide rail 307. During this process, the piston 404 slides within the air control chamber 403, creating a negative pressure inside the air control chamber 403. This draws gas from the annular airbag 105 into the air control chamber 403 through the connecting pipe 401, achieving rapid deflating of the annular airbag 105. At this time, the annular airbag 105 contracts, and the opening of the interface cavity 102 is unsealed, reserving space for plug rotation, avoiding airbag interference with rotation, and ensuring smooth rotation.

[0061] When the guide post 308 enters the second turning section of the guide rail 307, the guide rod 303 continues to move along the controlled path and drives the rotating shaft 104 to rotate. The plug body 103 completes the flipping from inward to outward, realizing the automatic docking action of the plug. The entire process is completed by the guide rail 307, the piston 404 evacuating air, and the annular airbag 105 contracting in coordination, and the action is natural and continuous.

[0062] When the sliding sleeve 101 slides further to the third section of the guide rail 307, the piston 404 resets under the action of the spring b405, and the gas in the gas control chamber 403 is forced back into the annular airbag 105. The airbag expands again and covers the plug and interface mating area, achieving a sealed closure of the plug port. At this time, the connection is completed and a sealing state is established, preventing moisture or impurities from entering and ensuring the stability and long-term safety of the electrical connection.

[0063] When disconnecting, the user pulls the sliding sleeve 101 in the opposite direction, and the guide post 308 moves in the opposite direction along the guide rail 307. First, when passing through the first sliding section, the piston 404 moves forward again to draw air, and the annular airbag 105 deflates and contracts, releasing the seal around the interface and preventing the airbag from obstructing the plug's rotation. Then, the guide post 308 enters the second tilting section, guiding the guide rod 303 to rotate the rotating shaft 104 in the opposite direction, causing the plug body 103 to turn from an outward-facing state back to an inward-facing state and retract into the interface cavity 102. Finally, the guide post 308 enters the third sliding section, and the piston 404 resets under the action of the spring b405, forcing the gas in the control chamber 403 back into the annular airbag 105, causing the airbag to re-inflate and seal the interface opening, achieving a sealed closure of the plug port.

[0064] Through the above two processes, the present invention achieves a two-way linkage closed-loop control of "deflation-rotation-inflation", ensuring that the automatic rotation of the plug and the dynamic sealing of the airbag are synchronized during the connection and disconnection process. It has significant technical effects of simple operation, reliable structure and high protection level.

[0065] In this embodiment, a connecting strip 500 is slidably connected to the gas control cavity 403, and a boss 501 is provided on the connecting strip 500. The boss 501 can contact the top contact surface of the connecting frame 306 during the movement of the connecting frame 306.

[0066] The piston 404 is fixedly connected to the connecting bar 500, so that when the connecting bar 500 is displaced, the piston 404 can be driven to slide in the air control chamber 403 in a synchronous manner.

[0067] With the above configuration, during the use of the electrical connector, the sliding sleeve 101 pushes the connecting rod 305, causing the connecting frame 306 to shift. During this movement, the connecting frame 306 contacts the boss 501 on the connecting strip 500, forcing the connecting strip 500 to slide axially along the air control chamber 403. Since the connecting strip 500 and the piston 404 are fixed together, the displacement of the connecting strip 500 is directly transmitted to the piston 404, causing the piston 404 to move forward or backward within the air control chamber 403. When the sliding sleeve 101 moves to the first two sections of the guide rail 307, the connecting frame 306 continuously presses against the boss 501, driving the connecting strip 500 and the piston 404 to move, creating a negative pressure within the air control chamber 403 to draw air from the annular airbag 105, thus achieving the deflation and contraction of the airbag.

[0068] As the sliding sleeve 101 further enters the third section of the guide rail 307, the connecting bracket 306 gradually disengages from the boss 501. Under the elastic force of the spring b405, the connecting bar 500 drives the piston 404 to reset in the reverse direction. When the piston 404 resets, the volume of the gas control chamber 403 increases, pushing the gas back into the annular airbag 105, causing the airbag to re-inflate and tightly fit the interface area. During the unplugging process, the connecting bracket 306 moves in the reverse direction, also contacting the connecting bar 500 through the boss 501, driving the piston 404 to complete the reverse action of "venting - plug rotation - inflation" in sequence, realizing the automatic retraction of the plug and the sealing closure in the non-working state.

[0069] In this embodiment, a spring c502 is connected between the connecting frame 306 and the connector housing 100.

[0070] With the above settings, during the insertion connection, the movement of the sliding sleeve 101 can stretch the spring c502, allowing it to generate potential energy. After normal insertion is completed, the snap-fit ​​piece 203 snaps into the snap-fit ​​groove on the sliding sleeve 101 to achieve structural locking, ensuring that the sliding sleeve 101 is stable and does not shift in the connected state, avoiding accidental disengagement caused by external force, and improving the overall vibration resistance and operational reliability of the connector.

[0071] When disconnection is required, the user can manually move the connecting rod 202 to disengage the locking tab 203 on the connecting rod 202 from the locking slot, thereby quickly unlocking the sliding sleeve 101. As the locking tab 203 is released, the spring c502, which was originally in a stretched state, quickly releases its stored elastic energy, pushing the connecting bracket 306 to slide in the retraction direction, thereby driving the sliding sleeve 101 to pull out through the elastic force, thus enabling the electrical connector to be quickly pulled out.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
