A quick-release pneumatic-electric hybrid connector

Abstract

This invention discloses a quick-release gas-electric hybrid connector, belonging to the field of connector technology. It includes a plug, socket, insertion terminals, connection terminals, and an isolation guide assembly. The isolation guide assembly includes a flame-retardant partition, guide holes, a connecting diaphragm, a slider, multiple guide grooves, and a limiting strip. This invention, through the isolation guide assembly, ensures that gas and electrical connection failures do not interfere with each other when a high-temperature combustion failure occurs at the connection between the insertion terminals and the connection terminals. This guarantees the safety of the gas connection between the gas tube and the guide hole. It solves the problem that when a high-temperature combustion flame caused by abnormally increased contact resistance, overload, or arc discharge at the electrical connection spreads to adjacent gas connection points, leading to gas circuit seal damage and leakage, the pressure generated by the leaked gas will act back on the electrical connection, causing poor contact and mutual interference between gas and electrical connection failures, significantly reducing the safety of gas-electric hybrid connections.

Description

Technical Field

[0001] This invention relates to the field of connector technology, and specifically to a quick-release pneumatic-electric hybrid connector. Background Technology

[0002] The pneumatic connector consists of two parts: a plug and a socket. The technology uses multiple structural components assembled together to achieve a dual mixed connection function of pneumatic and electrical circuits. This satisfies the simultaneous transmission of multiple electrical signals and the delivery of gas connections, saving power consumption of testing equipment and improving the efficiency of gas connection.

[0003] Among the existing published documents, patent publication number CN209487795U discloses a hybrid pneumatic and pneumatic electrical connector. This technology achieves pneumatic conduction when the plug and socket are mated through the connection of a pneumatic plug and a pneumatic socket, enabling the connector to have both electrical and pneumatic connection forms. Furthermore, the connection between the connecting mechanism and the locking sleeve ensures the stability of the pneumatic conduction by locking the pneumatic path. The positioning steps and positioning grooves not only position the plug housing on the socket housing but also guide the mating of the pneumatic plug and socket, ensuring the accuracy of the pneumatic conduction. The overall space utilization is high, and the structure is compact. However, this device still has the following problems.

[0004] While gas-electric hybrid connectors allow for quick disassembly via snap-fit, they pose a safety hazard: when the electrical connection experiences abnormally high contact resistance, overload, or arc discharge leading to high-temperature combustion, the flame can spread to adjacent gas connections, causing damage to the gas seals and resulting in air leakage. If high-pressure air leaks from the gas connection due to damage, the pressure generated by the leaking gas can act on the electrical connection, causing the electrical contacts to loosen or deform, leading to poor contact. This chain reaction causes gas and electrical connection faults to interfere with each other, increasing the risk of equipment damage and making it difficult to ensure that gas and electrical connection faults do not interfere with each other, significantly reducing the safety of gas-electric hybrid connections. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-release pneumatic-electric hybrid connector, comprising a plug, one end of which is inserted into a socket, a plug terminal fixedly connected to the inner wall of the plug, a connection terminal fixedly connected to the inner wall of the socket, and an isolation guide assembly provided below the plug terminal. The isolation guide assembly includes: a flame-retardant partition located below the plug terminal and fixedly connected to the inner wall of the plug, the flame-retardant partition being used to prevent the downward spread of flame; a guide hole opened at the top of the inner wall of the plug, a connecting diaphragm installed on the inner wall of the guide hole, and the connecting diaphragm being fixedly connected to the plug; a slider fixed to the upper surface of the connecting diaphragm, and the slider being slidably connected to the plug to which the guide hole belongs; and multiple guide grooves all opened on the inner wall of the guide hole, a limiting strip provided below the connecting diaphragm, the limiting strip being used to provide support for the falling slider.

[0006] Preferably, the plug-in terminal is plugged into the connecting terminal, and the flame-retardant partition is in contact with the socket. The height of the top surface of the inner wall of the guide groove is lower than the height of the lower surface of the connecting diaphragm, and the limiting strip is fixedly connected to the plug.

[0007] Preferably, the device includes a V-shaped cover located below the flame-retardant partition, the V-shaped cover being fixedly connected to the plug and abutting against the socket; a connecting air tube fixedly connected to the inner wall of the socket and located below the V-shaped cover, one end of the connecting air tube being connected to a connecting air tube; a guide hole opened at the bottom of the inner wall of the plug, a fixing plate installed on the inner wall of the guide hole, the fixing plate being fixedly connected to the plug; two arc-shaped springs fixedly fixed to the two bottom ends of the fixing plate, each arc-shaped spring having a sealing gasket fixedly connected to both sides, the sealing gasket being slidably connected to the plug to which the guide hole belongs, each arc-shaped spring having a linkage block fixedly connected to the bottom end of each arc-shaped spring, each linkage block having an arc-shaped sleeve fixedly fixed to its outer wall, the arc-shaped sleeve being slidably connected to the plug to which the guide hole belongs; and a folding spring fixedly installed between the two arc-shaped springs, the folding spring having a drainage groove on its upper part and a diversion groove on its lower part. The socket is fixedly connected to the connecting air pipe. The upper inclined surfaces of the two arc-shaped springs are provided with grooves with a vertical cross-section of arc shape. The sealing side gasket and the arc-shaped sleeve are both made of silicone material. The two arc-shaped springs are symmetrically arranged about the folding spring.

[0008] Preferably, each snap-fit ​​spring is fixedly connected to the outer wall of the plug, and the snap-fit ​​spring is snapped into the socket.

[0009] Preferably, a circuit board is fixed to one end of a plug-in terminal, the circuit board is fixedly connected to a plug, and multiple communication terminals are installed on one side of the circuit board and below a flame-retardant partition, the communication terminals are plugged into a socket.

[0010] Preferably, the vertical cross-sectional shape of the plurality of communication terminals is circular, and the outer wall of the communication terminals is smooth.

[0011] The present invention has the following advantages:

[0012] 1. This invention, through the isolation guide component, prevents high-temperature combustion caused by abnormally increased contact resistance, overload, or arc discharge at the connection between the plug terminal and the connecting terminal. The flame-retardant partition located below the plug terminal provides flame-retardant and heat-insulating protection. After the connecting diaphragm is damaged by combustion, the slider slides down along the guide hole under the action of gravity, allowing the high-temperature hot air to flow upward rapidly along multiple guide grooves on the inner wall of the plug, achieving simultaneous discharge from multiple points. In this way, the high-temperature hot air no longer continuously impacts the flame-retardant partition, and the flame and high-temperature air flow upward rapidly, effectively preventing the high temperature of combustion from spreading downward. This ensures that the gas and electrical connections do not interfere with each other when there is a fault, guaranteeing the safety of the gas connection between the gas pipe and the guide hole. Furthermore, the plug and socket can be quickly snapped together and separated by a snap-fit ​​method, thus improving the efficiency of snap-fit ​​disassembly.

[0013] 2. When the connection between the connecting tube and the insert tube leaks, the high-pressure gas leaks into the area below the V-shaped cover. The linkage block drives the arc-shaped spring strip to deform, causing the arc-shaped sleeve to separate from the inner wall of the guide hole. The arc-shaped spring strip no longer seals the drainage groove and the diversion groove. In this way, the high-pressure gas can be quickly guided and discharged along multiple areas such as the inner walls of the guide hole, the inside of the drainage groove, and the inside of the diversion groove. This avoids damage to the V-shaped cover due to gas pressurization, prevents the plug and socket from separating, avoids poor contact between the plug terminal and the connection terminal, ensures that the gas and electrical connection do not interfere with each other in case of failure, and guarantees normal conductive connection.

[0014] 3. In terms of electrical faults, when the connection between the plug-in terminal and the connecting terminal is subjected to high-temperature combustion, the thermal force generated by the fault is used to ensure that gas and electrical faults do not interfere with each other, thus ensuring the safety of the gas connection. In terms of gas faults, when the gas connection tube and the plug-in gas tube leak, the high-pressure gas generated by the fault causes the arc sleeve to separate, and the arc elastic strip no longer seals the drainage groove and the diversion groove, thus realizing rapid gas diversion in multiple areas. Electrical faults do not interfere with each other, which is energy-saving and reliable, and ensures normal conductive connection. Attached Figure Description

[0026] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0027] like Figure 1 - Figure 8 The quick-release pneumatic-electric hybrid connector shown has an isolation guide component. The isolation guide component ensures that the pneumatic and electrical connections do not interfere with each other when a high-temperature combustion fault occurs at the connection between the plug terminal 3 and the connecting terminal 4. This ensures the safety of the pneumatic connection between the connecting gas tube 13 and the guide hole 14. When there is a leak at the connection between the connecting gas tube 13 and the plug gas tube 12, it prevents poor contact between the plug terminal 3 and the connecting terminal 4 and ensures normal conductive connection. The specific structure of the isolation guide component is as follows.

[0028] In this embodiment, as Figure 1 - Figure 4 As shown, a socket 2 is inserted into one end of the plug 1. A plug terminal 3 is fixedly connected to the inner wall of the plug 1. A connection terminal 4 is fixedly connected to the inner wall of the socket 2. An isolation guide assembly is provided below the plug terminal 3. The isolation guide assembly includes: a flame-retardant partition 5, located below the plug terminal 3, and fixedly connected to the inner wall of the plug 1. The flame-retardant partition 5 is used to prevent the downward spread of flames; and a guide hole 6, which is opened at the top of the inner wall of the plug 1. A connecting diaphragm 7 is installed on the inner wall of the guide hole 6, and the connecting diaphragm 7 is fixedly connected to the plug 1.

[0029] The slider 8 is fixed to the upper surface of the connecting diaphragm 7 and is slidably connected to the plug 1 belonging to the guide hole 6. Multiple guide grooves 9 are formed on the inner wall of the guide hole 6. A limiting strip 10 is provided below the connecting diaphragm 7 to provide support for the falling slider 8. The plug terminal 3 is plugged into the connecting terminal 4, and the flame-retardant partition 5 is in contact with the socket 2. The height of the top surface of the inner wall of the guide groove 9 is lower than the height of the lower surface of the connecting diaphragm 7. The limiting strip 10 is fixedly connected to the plug 1 so that the connection between the plug terminal 3 and the connecting terminal 4 can discharge and ignite high-temperature combustion. First, the connecting diaphragm 7 is burned and damaged. Under the gravity of the slider 8, it moves downward until the slider 8 contacts the limiting strip 10. The generated high-temperature hot air is guided upward along the multiple guide grooves 9 on the inner wall of the plug 1, and the high-temperature hot air and the combustion flame are all directed upward to achieve multi-point synchronous discharge.

[0030] In this embodiment, as Figure 2 - Figure 7 As shown, the isolation guide assembly also includes: a V-shaped cover 11, located below the flame-retardant partition 5, the V-shaped cover 11 being fixedly connected to the plug 1 and abuttingly connected to the socket 2; an insert air tube 12, fixedly connected to the inner wall of the socket 2 and located below the V-shaped cover 11, with a connecting air tube 13 inserted into one end of the insert air tube 12; a guide hole 14, opened at the bottom of the inner wall of the plug 1, with a fixing plate 15 installed on the inner wall of the guide hole 14, and the fixing plate 15 being fixedly connected to the plug 1; and two arc-shaped elastic strips 16, respectively fixed to the two ends of the fixing plate 15. At the bottom, each arc-shaped spring strip 16 has a sealing gasket 17 fixedly connected to both sides, and the sealing gasket 17 is slidably connected to the plug 1 to which the guide hole 14 belongs. Each arc-shaped spring strip 16 has a linkage block 19 fixedly connected to its bottom end, and an arc-shaped sleeve 18 is fixedly attached to the outer wall of each linkage block 19. The arc-shaped sleeve 18 is slidably connected to the plug 1 to which the guide hole 14 belongs. A folding spring piece 20 is fixedly installed between the two arc-shaped spring strips 16. A drainage groove 21 is provided above the folding spring piece 20, and a diversion groove 22 is provided below the folding spring piece 20. The socket 2 is fixedly connected to the connecting air pipe 13. The upper inclined surface of each of the two arc-shaped spring strips 16 has a groove with a vertical cross-section of arc shape. The sealing gasket 17 and the arc-shaped sleeve 18 are both made of silicone material, and the two arc-shaped spring strips 16 are symmetrically arranged about the folding spring piece 20.

[0031] When there is no leakage, the arc-shaped spring strip 16 drives the sealing gasket 17 to the top area of ​​the drain groove 21. At this time, the drain groove 21 is sealed by the sealing gasket 17. Simultaneously, the arc-shaped spring strip 16 drives the sealing gasket 17 to the top area of ​​the sealing diversion groove 22, and the sealing diversion groove 22 is also sealed by the sealing gasket 17. When there is a leakage, the high-pressure gas can be limited to the area below the V-shaped cover 11 through the V-shaped cover 11. The high-pressure gas compresses the two arc-shaped sleeves 18, and the linkage block 19 drives the arc-shaped groove on the inclined surface of the arc-shaped spring strip 16 to deform. At the same time, the fixing plate 15 provides firm support to the top of the two arc-shaped spring strips 16. The arc-shaped spring strip 16 drives the sealing gasket 17 to deform and rotate counterclockwise, while the other arc-shaped spring strip 16 drives the sealing gasket 17 to deform and rotate clockwise. In this way, the two arc-shaped spring strips 16 can... The folding spring 20 is compressed to achieve the folding operation. The arc sleeve 18 and the left side of the inner wall of the guide hole 14 begin to separate in linkage, while the other arc sleeve 18 and the right side of the inner wall of the guide hole 14 separate in linkage. At the same time, the arc spring strip 16 no longer seals the drain groove 21, and the arc spring strip 16 no longer seals the diversion groove 22. This allows the high-pressure gas to be quickly guided downward and discharged along both sides of the inner wall of the guide hole 14. Another part of the high-pressure gas is also quickly guided outward and discharged along the inside of the drain groove 21 and the inside of the diversion groove 22.

[0032] In this embodiment, as Figure 8As shown, each snap-fit ​​spring block 23 is fixedly connected to the outer wall of the plug 1. The snap-fit ​​spring block 23 is snapped into the socket 2 so that when disassembling quickly, the plug 1 can forcefully move multiple snap-fit ​​spring blocks 23 to the right, so that the snap-fit ​​spring blocks 23 can be squeezed and deformed at the protruding part of the socket 2 to separate, so that the plug 1 and the socket 2 are no longer snapped together, and the disassembly can be completed quickly.

[0033] In this embodiment, as Figure 2 - Figure 3 As shown, circuit board 25 is fixed to one end of plug terminal 3. Circuit board 25 is fixedly connected to plug 1. Multiple communication terminals 24 are installed on one side of circuit board 25 and below flame retardant partition 5. Communication terminals 24 are plugged into socket 2. The vertical cross-section of multiple communication terminals 24 is circular. The outer wall of communication terminals 24 is smooth to facilitate conductive connection between connection terminal 4 and plug terminal 3. Plug terminal 3 is conductively connected to circuit board 25. Finally, circuit board 25 conducts electricity to the test equipment. Multiple communication terminals 24 conduct electricity by plugging into socket 2, and then communication terminals 24 also conduct electricity to circuit board 25.

[0034] The usage process of the quick-release pneumatic-electric hybrid connector of the present invention is as follows:

[0035] Step 1: During installation and connection, the plug terminal 3 is positioned at the top and the gas tube 12 is positioned at the bottom. Plug 1 and socket 2 are inserted together. Simultaneously, plug 1 moves plug terminal 3 to the left, inserting it into the connection terminal 4. Plug 1 also moves flame-retardant partition 5 to the left, pressing against the right end of socket 2. Plug 1 also causes gas tube 12 to be inserted into and sealed with connection tube 13. In this way, flame-retardant partition 5 can seal and isolate the connection between plug terminal 3 and connection terminal 4.

[0036] Simultaneously, plug 1 causes V-shaped cover 11 to press against the right end of socket 2, thus isolating and sealing the insertion air tube 12 and connecting air tube 13. At the same time, plug 1 causes multiple snap-fit ​​springs 23 to move to the left, deforming and snapping against the protruding part on socket 2, thus completing the snap-fit ​​connection between plug 1 and socket 2. The connection is electrically connected to insertion terminal 3 via connection terminal 4, which is electrically connected to circuit board 25. Circuit board 25 supplies power to the test equipment. Multiple communication terminals 24 are also electrically connected to circuit board 25 through insertion into socket 2, completing the electrical connection operation. Simultaneously, high-pressure gas flows through the connecting air tube 13 inside socket 2, enters insertion air tube 12, and is then supplied to the gas supply pipeline of the test equipment, achieving gas connection. During normal use, the connecting diaphragm 7 supports the slider 8, which can isolate the guide hole 6 from dust. The sealing side gaskets 17 on the two arc sleeves 18 and the arc elastic strip 16 fit together to protect the area of ​​the guide hole 14 from dust.

[0037] Step 2, during the electrical fault isolation and guidance process, when the connection between the plug terminal 3 and the connecting terminal 4 is subjected to abnormally increased contact resistance, overload, or arc discharge leading to high-temperature combustion, a flame-retardant partition 5 positioned below the plug terminal 3 provides flame-retardant and heat-insulating protection, and also burns the connecting diaphragm 7. After the connecting diaphragm 7 is damaged by combustion, under the gravity of the slider 8, the slider 8 slides down along the inner wall of the guide hole 6. When the lower surface of the slider 8 contacts the upper surface of the limiting strip 10, the limiting strip 10 provides downward support for the lower surface of the slider 8, thus preventing combustion at the connection between the plug terminal 3 and the connecting terminal 4. The high-temperature hot air generated begins to flow upwards along the multiple guide grooves 9 inside the inner wall of the plug 1, achieving a large-area upward flow. The multiple guide grooves 9 can simultaneously and rapidly guide the high-temperature hot air of combustion upwards, so that the high-temperature hot air generated at the connection between the plug terminal 3 and the connection terminal 4 can be rapidly discharged and guided at multiple points simultaneously. At this time, the high-temperature hot air of combustion will not continuously generate high temperature on the flame-retardant partition 5. Instead, the high-temperature air and the combustion flame area are guided upwards, which can prevent the high temperature of combustion from spreading downwards and affecting the normal gas connection between the gas pipe 13 and the guide hole 14.

[0038] Step 3, during the gas fault isolation and guidance process, if a leak occurs at the connection between the connecting air pipe 13 and the insert air pipe 12, the high-pressure gas leaks into the V-shaped cover 11 through the connection between the connecting air pipe 13 and the insert air pipe 12. The V-shaped cover 11 can limit the high-pressure gas to the area below the V-shaped cover 11. In this way, the high-pressure gas enters the guide hole 14 and squeezes the two arc-shaped sleeves 18. The arc-shaped sleeves 18 are forced to move the linkage block 19 downward. The linkage block 19 causes the arc groove on the inclined surface of the arc-shaped spring strip 16 to deform, so that the fixing plate 15 provides support for the top of the two arc-shaped spring strips 16, while the bottom of the two arc-shaped spring strips 16 deforms and moves closer to each other. Thus, the arc-shaped spring strip 16 causes the sealing side gasket 17 to deform and rotate counterclockwise, while the other arc-shaped spring strip 16 causes the sealing side gasket 17 to deform and rotate clockwise, and the bottom of the two arc-shaped spring strips 16 move closer to each other. The arc-shaped sleeve 18 separates from the left side of the inner wall of the guide hole 14, while the other arc-shaped sleeve 18 separates from the right side of the inner wall of the guide hole 14. Simultaneously, the arc-shaped spring strip 16 rotates counterclockwise along the drain groove 21, no longer sealing the drain groove 21. At the same time, the arc-shaped spring strip 16 rotates counterclockwise along the diversion groove 22, no longer sealing the diversion groove 22. In this way, the high-pressure gas flows rapidly downwards and outwards along both sides of the inner wall of the guide hole 14. At the same time, the high-pressure gas also flows rapidly outwards and outwards along the inside of the drain groove 21. This multi-area rapid flow of high-pressure gas prevents the V-shaped cover 11 from being damaged due to continuous pressure increase, thus preventing the plug 1 and socket 2 from being filled with high-pressure air and causing separation problems, and preventing poor contact between the plug terminal 3 and the connection terminal 4. This avoids affecting the normal conductive connection between the plug terminal 3 and the connection terminal 4.

[0039] Step 4: When using the quick disassembly method, after use, hold and fix the socket 2 with one hand, and use the other hand to forcefully move the plug 1 to the right. The plug 1 forcefully drives multiple locking springs 23 to move to the right and deform along the protruding part of the socket 2. As a result, the locking springs 23 deform under force and the protruding part of the socket 2 deforms under force and moves downward, so that the plug 1 and the socket 2 are no longer locked and can be quickly disassembled.
