Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a blind-mounted connector with a deviation absorption function. Background Art

[0002] Fluid transmission systems are an indispensable and important part of many fields of modern industry, such as aerospace, automobile manufacturing, industrial automation, petrochemicals, etc. These systems transmit and distribute fluid media (such as hydraulic oil, gas, various chemical liquids, etc.) between different components, equipment or subsystems through various pipes and connectors to achieve specific functions and processes.

[0003] Traditional connectors have many limitations in design and application. During the assembly process, the connection accuracy requirements are extremely high, and the male and female ends must be precisely aligned to achieve an effective connection. This requirement faces many challenges in actual operation scenarios. For example, in some environments with small spaces and limited operating space, it is difficult for operators to directly observe the connection parts, or due to the complex equipment layout, it is difficult to ensure accurate coaxiality and angle alignment. In this case, the assembly of traditional connectors often requires a lot of time for repeated adjustments and attempts, which not only seriously reduces production efficiency, but also increases labor costs and labor intensity.

[0004] At the same time, if there is a slight position deviation during connection that is not discovered or corrected in time, even if the connection can be completed, it is very likely to cause a series of problems during subsequent use. For example, since the sealing surface cannot be completely fitted, the sealing performance will be reduced, causing fluid leakage. Summary of the invention

[0005] In view of the above-mentioned deficiencies existing in the prior art, the present invention provides a blind-mounted connector with a deviation absorption function, which is used to solve the problems in the prior art that the sealing surfaces cannot be fully fitted, resulting in reduced sealing performance and causing fluid leakage.

A female end color identification ring 5 is provided on the outside of the female end B. An arc surface 130 is provided in the middle section of the male end upper shell 13.

[0031] A female end valve core sealing ring 9 is provided on the upper part of the female end valve column 11, a female end inner sealing ring 7 is provided on the lower part of the female end valve core sealing ring 9, a female end isolation ring 8 is provided between the female end valve core sealing ring 9 and the female end inner sealing ring 7, and a female end connecting sealing ring 6 is provided at the bottom of the female end upper shell body 1.

[0032] The female end B is mainly composed of the female end upper shell 1, the female end lower shell 2, the female end sleeve 3 and the female end valve body C. The female end upper shell 1 and the female end lower shell 2 are connected in a disassembly manner to facilitate the installation and maintenance of the internal components. A female end outer sealing ring 12 is installed at the connection between the two to ensure effective isolation of the external environment and the internal fluid channel to prevent fluid leakage.

[0033] The female valve body C is the core functional component of the female end, which includes a female valve core 4, a female return spring 10 and a female valve column 11. The female valve core 4 is installed on the upper end of the female return spring 10, and the female return spring 10 is installed on the upper part of the female valve column 11.

[0034] The male end A is composed of a male upper shell 13, a male lower shell 14, a male upper shell locking nut 15, a male upper shell locking sleeve 16 and a male locking cover 17. The male upper shell 13 is detachably connected to the male lower shell 14 through the male upper shell locking nut 15, and this connection method is convenient for the assembly and adjustment of internal parts. The male upper shell locking sleeve 16 is detachably connected to the male upper shell locking nut 15, and the male locking cover 17 is detachably connected to the male upper shell 13, providing stable packaging and protection for the internal structure. A male valve body D is provided inside the male upper shell 13, and the male valve body D includes a male correction rod 18, a male valve core 20, and a male reset spring 26. The male end correction rod 18 is installed on the top of the male end reset spring 26, and two sets of correction sealing rings 21 are provided on the outer ring, and a male end spring support seat 19 is provided at the bottom. The upper end of the male end spring support seat 19 is provided with a male end stop spring 23. These structural designs ensure the stability and sealing of the male end correction rod 18 during movement. The male end valve core 20 is installed at the bottom of the male end reset spring 26, and a male end valve core sealing ring 25 is provided at the bottom, which cooperates with the corresponding structure of the female end to achieve sealing and conduction functions during the connection and disconnection process. The male end lower shell 14 is provided with a male end color identification ring 24, which corresponds to the female end color identification ring 5, so as to facilitate the distinction between the male and female ends. The male end upper shell 13 is provided with a male end outer sealing ring 22 to prevent external impurities from entering and ensure the overall sealing performance of the male end. The middle section of the male end upper shell 13 is provided with an arc surface 130, which plays a good guiding role in the initial stage of connection, helps the male end to be smoothly inserted into the female end, and can guide the two to gradually align even if there is a certain deviation.

[0035] The male end correction rod 18 is at the top position under the action of the male end return spring 26, the male end valve core 20 is at the bottom position, the male end valve core sealing ring 25 contacts the corresponding sealing surface inside the male end lower housing 14, and the male end stop spring 23 clamps the male end spring support seat 19 to prevent the male end return spring 26 from being over-compressed or the male end correction rod 18 from coming out. The male end outer sealing ring 22 ensures the sealing between the male end upper housing 13 and the outside.

[0036] The female end valve core 4 is in the top position under the action of the female end return spring 10, the female end connection sealing ring 6 and the female end inner sealing ring 7 are in contact with the corresponding sealing surfaces inside the female end upper shell 1 and the female end lower shell 2, the female end valve core sealing ring 9 is in contact with the top sealing surface of the female end valve column 11, and the female end outer sealing ring 12 ensures the sealing at the connection between the female end upper shell 1 and the female end lower shell 2.

[0037] When the male end A and the female end B begin to dock, the male end plug approaches the female end connector. Since the middle section of the male end upper shell 13 is provided with an arc surface 130, it is convenient to initially guide the docking to a certain extent, and the arc surface structure of the male end upper shell 13 is not specifically named, it can be understood that the movable structure formed by the connection part of the male end upper shell 13 and the male end lower shell 14 can adapt to the position of the female end within a certain range, even if there is a certain coaxial deviation and angle deviation, the arc surface structure of the male end upper shell 13 can achieve radial displacement or rotation around its spherical center to automatically absorb the position deviation.

[0038] As the male plug is further inserted into the female connector, the end face of the male plug gradually abuts against the end face of the valve core in the female connector, and the valve core in the male plug gradually abuts against the end face of the central support column of the lower shell of the female connector. In this process, the male correction rod 18 is compressed, the male reset spring 26 is deformed by force, the male valve core 20 moves upward, and the male valve core sealing ring 25 is out of contact with the internal sealing surface of the male lower shell 14; at the same time, the female valve core 4 is compressed, the female reset spring 10 is deformed by force, the female connection sealing ring 6 and the female inner sealing ring 7 are out of contact with the internal sealing surfaces of the female upper shell 1 and the female lower shell 2, and the female valve core sealing ring 9 is out of contact with the top sealing surface of the female valve column 11, thereby realizing a passage for fluid to flow through.

[0039] When the male plug and the female connector need to be disconnected, the external force pulls the male plug out. The male reset spring 26 begins to recover its deformation, pushing the male correction rod 18 back to the initial position, the male valve core 20 moves downward, and the male valve core sealing ring 25 contacts the internal sealing surface of the male lower shell 14 again; at the same time, the female reset spring 10 recovers its deformation, pushing the female valve core 4 back to the initial position, the female connection sealing ring 6 and the female inner sealing ring 7 contact the internal sealing surfaces of the female upper shell 1 and the female lower shell 2 again, and the female valve core sealing ring 9 contacts the top sealing surface of the female valve column 11 again, realizing two-way rapid sealing and interception to prevent fluid overflow.

[0040] The arc surface structure and related design of the male upper shell 13 enable the male and female ends to automatically absorb the position deviation, coaxial deviation and angle deviation when connected, which greatly improves the convenience and success rate of the connector during blind installation. The operator does not need to accurately align the male and female ends, and can successfully complete the connection even within a certain deviation range, reducing assembly time and difficulty, especially suitable for some connection scenarios that are difficult to directly observe or have limited operating space.

[0041] Whether in the connected or disconnected state, there is a corresponding sealing ring structure to ensure sealing. When connected, the seal ring is disengaged through the movement of the valve core to achieve passage, and when disconnected, the seal ring can quickly restore the sealing state, effectively preventing fluid leakage. The two-way sealing interception effect is good, ensuring the sealing and stability of the system, and can be applied to a variety of fluid transmission systems with high sealing requirements.

[0042] The return spring and retaining spring of the male and female ends are formed by winding, and the rest, except the sealing ring, are formed by injection molding or machining. This choice of manufacturing process not only ensures the accuracy and strength of the parts, but also facilitates large-scale production and manufacturing. Each part has a clear division of labor, and a complete connector function system is formed through reasonable assembly. For example, the valve core, spring and other parts in the male valve body D and the female valve body C work together to realize the switching of connection and sealing functions. The overall structure is compact and the function is efficient.

[0043] Blind-mounted connectors with the function of absorbing deviation have broad application prospects in many industrial fields due to their unique advantages. In the field of aerospace, there are many hydraulic and pneumatic systems inside the aircraft, and the space is limited. This connector can easily and quickly realize pipeline connection, improve assembly efficiency and ensure system reliability; in the automotive manufacturing industry, various fluid pipeline connections in the engine compartment can also benefit from its blind-mounted characteristics, reducing assembly time and cost; in industrial automation production lines, a large number of fluid transmission pipelines need to be frequently connected and disconnected. The fast blind-mounted and reliable sealing performance of this connector can significantly improve the operating efficiency and stability of the production line. With the continuous development of industrial technology, the performance requirements for connectors will become higher and higher. Blind-mounted connectors with the function of absorbing deviation are expected to be applied and promoted in more fields, and with the advancement of material science and manufacturing technology, their performance will be further optimized, such as improving high pressure resistance, high temperature resistance, corrosion resistance, etc., to meet the needs of more demanding industrial environments and make greater contributions to the development of industrial connection technology.

[0044] The blind-install connector with deviation absorption function has shown significant advantages in the field of industrial connection with its innovative structural design, excellent blind-installation capability, reliable sealing performance, reasonable manufacturing process and clear identification design. By elaborating on its structural composition, movement principle of the connection process and structural advantages, it can be seen that this connector has important value in improving assembly efficiency and ensuring system sealing and stable operation.
