Description

Technical Field

[0001] This utility model relates to the field of combined plug-in connector technology, specifically an electro-hydraulic combined transmission quick plug-in connector. Background Technology

[0002] In modern industry, especially in sectors like automotive manufacturing, electronics, and machinery, electrical signals and hydraulic or pneumatic media often need to be transmitted synchronously to the actuator. Traditionally, electrical circuits and fluid pipelines are laid out and connected separately, which is cumbersome and prone to human error. A highly efficient quick-connect connector enables integrated electro-hydraulic or pneumatic-electric transmission, significantly simplifying the connection process, improving assembly and maintenance efficiency, and reducing operational complexity. More importantly, a superior connector design ensures the connection interface remains stable during operation, preventing fluid leakage or circuit interruptions caused by vibration or pressure fluctuations, thus guaranteeing long-term reliable system operation.

[0003] Although electro-hydraulic transfer connectors have been used in industry, the currently prevalent structures still have several significant drawbacks. First, most existing connectors fail to achieve true integration of electrical connection and fluid transfer, still requiring separate connection of cables and pipes, a cumbersome process that hinders rapid assembly / disassembly and modular design. Second, in confined spaces, electrical and fluid circuits are often tightly packed, and the fluid channels lack sufficient sealing performance, making them prone to leakage or dripping over long-term use. Fluid can also corrode electrical contact points, leading to poor conductivity, short circuits, or insulation failure, posing safety hazards. Furthermore, common connection methods still rely on mechanical fastening such as threaded locking, which is time-consuming and labor-intensive, unable to meet the demands of high-frequency, high-efficiency insertion and removal, especially limiting their effectiveness in situations requiring rapid replacement or emergency disconnection.

[0004] Based on this, an electro-hydraulic combined transmission quick-connect connector is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a quick-connect and disconnect connector for electro-hydraulic combined transmission to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electro-hydraulic combined transmission quick-connect connector includes a plug component and a socket component.

The fixed tube is sleeved with the connecting ring. A connecting slot is provided at the end of the fixed tube and at the position of the snap-fit ​​block. Both sides of the end of the snap-fit ​​block are inclined. A third sealing ring is installed at both ends of the fluid insertion tube.

[0010] In one alternative: each end of the plug housing is symmetrically provided with a positioning rod, the end of the positioning rod is arc-shaped, and the inside of the fixing tube is provided with a positioning groove corresponding to the position of the positioning rod, the width of the positioning groove being several times greater than the width of the positioning rod.

[0011] In one alternative: the outer side of the connecting ring is provided with an indicator embossing.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-8 As shown, an electro-hydraulic combined transmission quick-connect connector includes a plug component and a socket component. The plug component includes a plug housing 11, inside which are installed a plurality of conductive pins 12 and fluid pins 13. Each end of the fluid pin 13 is connected to a first connecting pin 14. The socket component includes a socket housing 20, inside which are installed a plurality of conductive connecting tubes 21 and fluid connecting tubes 22. Each end of the fluid connecting tubes 22 is connected to a second connecting pin 23. The conductive connecting tubes 21 and the conductive pins 12 are engaged by plugging. The plug housing 11 has a quick-connect mechanism on its outer side that allows for quick connection with the socket housing 20. The fluid connecting tubes 22 have an automatic flow-stopping mechanism inside. The quick-connect mechanism facilitates quick connection and disconnection between the plug housing 11 and the socket housing 20. The flow-stopping mechanism allows for automatic sealing of one end of the fluid connecting tube 22 after the plug housing 11 is disconnected from the socket housing 20.

[0028] The quick-connect mechanism includes a fixing tube and a connecting ring 19. The connecting ring 19 is sleeved on the outside of the plug housing 11. A limiting slider 17 is symmetrically arranged inside the connecting ring 19. A guide groove 16 is provided in the middle of the plug housing 11. The limiting slider 17 is slidably disposed inside the guide groove 16. A first return spring 18 is fixedly installed on one side of one limiting slider 17. The other end of the first return spring 18 is slidably disposed at one end of the guide groove 16. A locking block 30 is symmetrically arranged at the other end of the connecting ring 19. A fixing tube is fixedly installed at the end of the socket housing 20. The fixing tube is sleeved with the connecting ring 19. A connecting groove 29 is provided at the end of the fixing tube and at the position of the locking block 30. Both sides of the end of the locking block 30 are inclined. A third sealing ring is installed at both ends of the fluid insertion tube 22. A first sealing ring 26 is provided between the fixing tube and the socket housing 20. In use, when it is necessary to connect the plug housing 11 and the socket housing 20, the conductive pin 12 is aligned with the end of the conductive connector 21, and the fluid pin 13 is aligned with the end of the fluid connector 22. Then, one end of the conductive pin 12 is inserted into the conductive connector 21, and the end of the fluid pin 13 is inserted into the fluid connector 22. When the locking block 30 is in close contact with the end of the connecting slot 29, the connecting ring 19 rotates under the action of the inclined surface at the end of the locking block 30. After the locking block 30 has completely moved into the connecting slot 29, the connecting ring 19 rotates to the initial state under the action of the first return spring 18, thereby completing the quick connection between the plug housing 11 and the socket housing 20. When it is necessary to separate the plug housing 11 and the socket housing 20, pinch the connecting ring 19 with your hand, rotate it counterclockwise by a quarter turn, and then apply axial force to separate the plug housing 11 and the socket housing 20.

[0029] The plug housing 11 is symmetrically provided with positioning rods 32 at each end. The ends of the positioning rods 32 are arc-shaped. The fixed tube is provided with positioning grooves 31 at the positions corresponding to the positioning rods 32. The width of the positioning grooves 31 is several times greater than the width of the positioning rods 32. In use, when the plug housing 11 is connected to the socket housing 20, the positioning rods 32 are inserted into the positioning grooves 31, which facilitates quick positioning during installation.

[0030] The outer side of the connecting ring 19 is provided with an indicator protrusion 33, which facilitates the user's operation during use.

[0031] The flow-stopping mechanism includes a sliding baffle 24, with a tapered head at one end and a fourth sealing ring at the other end. A tapered groove is located inside the fluid insertion tube 22 corresponding to the position of the tapered head. A second return spring 25 is provided between the end of the tapered head and one end of the second connecting pin 23. The diameter of the end of the sliding baffle 24 is equal to the diameter of the end of the fluid pin 13. In use, when the fluid pin 13 is inserted into the end of the sliding baffle 24, the end of the fluid pin 13 pushes the sliding baffle 24 to slide. As the sliding baffle 24 slides, it causes the tapered head to move, separating it from the tapered groove. This allows the fluid pin 13 to communicate with the inside of the fluid insertion tube 22. When the plug housing 11 separates from the socket housing 20, as the plug housing 11 and socket housing 20 gradually separate, the second return spring 25 engages with the tapered groove to seal the end of the fluid insertion tube 22, thus preventing fluid overflow.

[0032] The plug housing 11 has a first threaded section at its end, and a tail straight tube 15 is threadedly installed on the first threaded section, which facilitates the fixing of cables and pipes during use.

[0033] The socket housing 20 has a second threaded section at its end, and a second sealing ring 27 and a fixing nut 28 are fitted on the second threaded section, which facilitates the connection and installation of the socket housing 20 during use.

[0034] The above embodiment discloses an electro-hydraulic combined transmission quick-connect connector. When connecting the plug housing 11 and the socket housing 20, the conductive pin 12 is aligned with the end of the conductive connector tube 21, and the fluid pin 13 is aligned with the end of the fluid connector tube 22. Then, one end of the conductive pin 12 is inserted into the conductive connector tube 21 to complete the circuit connection. At the same time, the end of the fluid pin 13 is inserted into the fluid connector tube 22. When the snap-fit ​​block 30 is in close contact with the end of the connecting slot 29, the connecting ring 19 rotates under the action of the inclined surface of the snap-fit ​​block 30. After the snap-fit ​​block 30 moves completely into the connecting slot 29, the connecting ring 19 rotates to the initial state under the action of the first return spring 18, thereby completing the quick connection between the plug housing 11 and the socket housing 20. At the same time, the end of the fluid pin 13 pushes the sliding stop tube 24 to slide. When the sliding stop tube 24 slides, it drives the conical head to move, causing the conical head to separate from the conical slot, so that the fluid pin 13 communicates with the inside of the fluid connector tube 22.

[0035] When it is necessary to separate the plug housing 11 from the socket housing 20, pinch the connecting ring 19 with your hand, rotate it counterclockwise by a quarter turn, and then apply axial force to separate the plug housing 11 from the socket housing 20. As the plug housing 11 and the socket housing 20 gradually separate, under the action of the second return spring 25, the conical head and the conical groove cooperate to seal the end of the fluid tube 22, thereby preventing fluid from overflowing.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
