Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to an extended electrical connector and a rapid assembly method thereof. Background Technology

[0002] An electrical connector is an electromechanical component that uses mechanical structures to insert, remove, or lock, enabling electrical connections and signal transmission between conductors, components, and systems in a circuit. It also functions as a circuit connector, disconnector, adapter, and branch connector, simplifying circuit assembly and facilitating equipment maintenance and upgrades. It is widely used in electronic systems in aerospace, automotive, communications, and industrial control fields.

[0003] To meet the needs of complex electronic systems for synchronous transmission and centralized management of multiple circuits and various types of signals, and to address the pain points of ordinary electrical connectors having a fixed number of ports, limited functionality, and difficulty in adapting to equipment upgrades, expansions, or multi-device integration scenarios, a modular and scalable structural design is used to achieve flexible adjustment of connection configurations, reduce system wiring complexity, improve the convenience of equipment assembly and maintenance, and adapt to the high integration and scalability requirements of aerospace, industrial control, communication base stations, and other fields.

[0004] In the connection and locking process of male and female electrical connectors, existing technologies mostly use threaded nut locking structures. This structure requires rotating the nut to complete the connection locking and unlocking operations. The axial travel of a single thread is limited, and multiple rotations are required to achieve effective locking or unlocking. The operation steps are cumbersome and time-consuming, making it difficult to match the rapid assembly rhythm of automated production lines, and also unable to meet the needs of efficient plugging and unplugging in emergency equipment maintenance scenarios. Therefore, to address the above problems, an extended electrical connector and its rapid assembly method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an extended electrical connector and a rapid assembly method thereof to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An extended electrical connector and its rapid assembly method are disclosed, comprising a socket assembly and a plug assembly. An operating component is rotatably connected to the outer side of the plug assembly. The socket assembly includes a female connector with a sliding pin fixedly connected to its upper end. The operating component includes a rotating cylinder with a straight track on its inner side near the rear end, a spiral groove, a second arc-shaped groove, and an annular groove near the front end of the straight track, and a first arc-shaped groove near the front end. The plug assembly includes a male connector with a spring and a limiting ring fixedly connected to its outer side. The spring is fixedly connected to the inner side of the first arc-shaped groove, the sliding pin slides within the second arc-shaped groove, and the limiting ring is rotatably connected to the inner side of the rotating cylinder.

[0008] As a further optimization of the present invention, the female head has a slot at its front end, and a guide block and a pin are fixedly connected to the inside of the slot. The front end of the female head is inserted and mated with the male head through the slot and the pin.

[0009] As a further optimization of the present invention, the male connector has a groove near its left end that matches the guide block, and the guide block slides inside the groove of the male connector.

[0010] As a further optimization of the present invention, the straight channel, the spiral groove and the first arc groove are connected, the spiral groove is spiral in shape, and the second arc groove is arc in shape.

[0011] As a further optimization of the present invention, the rotating cylinder has a cylindrical channel near its front end, the first arc-shaped groove is connected to the cylindrical channel, the cylindrical channel extends out of the lower end of the rotating cylinder, and the cylindrical channel has an arc-shaped structure near its right end.

[0012] As a further optimization of the present invention, an arc-shaped rod is inserted inside the cylindrical channel, a rubber sealing ring is fixedly connected to the outside of the arc-shaped rod, the arc-shaped rod and the rotating cylinder are sealed by the rubber sealing ring, and a stop post is fixedly connected to the left side of the arc-shaped rod, the stop post being embedded in the annular groove.

[0013] As a further optimization of the present invention, a duckbill valve is fixedly connected to the inner side of the cylindrical channel, and a circulation hole is opened near the upper end of the duckbill valve, with the inner side of the duckbill valve communicating with the circulation hole.

[0014] As a further optimization of the present invention, the spring is embedded in the annular groove, and the outer periphery of the spring is fixedly connected to the inner side of the annular groove.

[0015] As a further optimization of the present invention, the male connector has an insertion hole on its inner side, a rubber plug is inserted into the insertion hole, a rubber pad is fixedly connected to the rear end of the rubber plug, and the rear end of the rubber pad is in contact with the front end of the female connector.

[0016] An extended electrical connector and its rapid assembly method;

[0017] Step 1: During installation, align the slot at the front of the female connector with the rear of the male connector, align the groove on the left side of the male connector with the guide block, insert the male connector into the slot, slide the guide block into the groove of the male connector, insert the pin into the male connector, and the sliding column enters the straight track. The straight track connects with the spiral groove. After the sliding column contacts the spiral groove, the spiral groove is spiral in shape. The sliding column will push the rotating cylinder to rotate. The rotating cylinder is rotatably connected to the limit ring. The rotating cylinder rotates outside the male connector, and the rotating cylinder drives the spring to deform. The spring generates elastic force and moves inside the first arc groove. The stop pin slides inside the annular groove. After the sliding column enters the second arc groove, the spring rotates under the action of the spring until the sliding column contacts the other end of the second arc groove, thus completing the installation.

[0018] Step 2: During the sealing process, when the male and the rotating cylinder are assembled, the rubber pad is in contact with the front end of the female head, the sliding column enters the second arc groove, the rubber pad is assembled between the rotating cylinder and the male head, the rubber pad is pulled back, the rubber pad drives the rubber plug to move away from the assembly hole, the rubber plug fixed by another rubber pad is aligned with the assembly hole, the rubber plug is squeezed, the rubber plug deforms and enters the assembly hole until the rubber pad is in contact with the male head;

[0019] Step 3: During disassembly, rotate the drum. The arc-shaped rod slides inside the cylindrical channel. When the arc-shaped rod slides away from the cylindrical channel, the rubber sealing ring seals, and external air enters the circulation hole through the duckbill valve. After the drum can no longer be rotated, the sliding column contacts the other end of the second arc groove. Release the drum. When the spring returns the drum to its original position, the gas inside the cylindrical channel enters the duckbill valve through the circulation hole and flows out.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the device can achieve rapid and accurate assembly of male and female connectors by means of the sliding column, rotating cylinder and male head, without the need for cumbersome rotation operation, and the assembly efficiency is high. The self-locking anti-disengagement design of the structure ensures the connection stability, while avoiding excessive rotation and damage to the components. It is suitable for the needs of rapid assembly and efficient plugging and unplugging in emergency maintenance of automated production lines.

[0022] 2. In this invention, through the set assembly holes, rubber plugs and rubber gaskets, the device completes the sealing simultaneously during the assembly process, effectively preventing moisture and impurities from entering the internal contact pins, ensuring safe and stable electrical connection. The sealing components adopt a modular design that can be quickly disassembled and installed, making replacement convenient, reducing maintenance costs and extending the overall service life of the connector.

[0023] 3. In this invention, the cylindrical channel, the second arc groove and the rubber sealing ring are designed to start and unlock with a single step of rotation. The operation is simple and does not require the cooperation of both hands. It is suitable for space-constrained scenarios. The airflow control is used to achieve slow reset, allowing sufficient time for component alignment and improving the safety and convenience of disassembly. Attached Figure Description

[0039] 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.

[0040] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0041] Please see Figures 1-12 The present invention provides a technical solution:

[0042] An extended electrical connector and its rapid assembly method are disclosed, comprising a socket assembly 1 and a plug assembly 3. An operating component 2 is rotatably connected to the outside of the plug assembly 3. The socket assembly 1 includes a female connector 11, with a sliding post 14 fixedly connected to the upper end of the female connector 11. The operating component 2 includes a rotating cylinder 21, with a straight track 22 formed on the inner side near the rear end of the rotating cylinder 21. A spiral groove 23, a second arc-shaped groove 26, and an annular groove 27 are formed on the front end of the rotating cylinder 21 near the straight track 22. A first arc-shaped groove 24 is formed on the front end of the rotating cylinder 21. The plug assembly 3 includes a male connector 31, with a spring 32 and a limiting ring 39 fixedly connected to the outside of the male connector 31. The spring 32 is fixedly connected to the inner side of the first arc-shaped groove 24. The sliding post 14 slides inside the second arc-shaped groove 26. The limiting ring 39 is rotatably connected to the inner side of the rotating cylinder 21.

[0043] As a further implementation of this solution, the female connector 11 has a slot 12 at its front end. A guide block 13 and a pin are fixedly connected to the inside of the slot 12. The front end of the female connector 11 is inserted into the male connector 31 through the slot 12 and the pin. With the above settings, the slot 12 provides a precise insertion positioning space. With the coordinated setting of the guide block 13 and the pin, the insertion of the female connector 11 and the male connector 31 is more directional, ensuring that the pin can accurately align with the corresponding interface inside the male connector 31. This avoids poor contact or component damage caused by insertion deviation, laying the foundation for subsequent rapid assembly. At the same time, it simplifies the alignment operation during assembly and improves assembly efficiency.

[0044] As a further implementation of this solution, a groove matching the guide block 13 is provided near the left end of the male connector 31. The guide block 13 slides inside the groove of the male connector 31. Through the above-mentioned setting, the matching sliding design of the guide block 13 and the groove further strengthens the guiding and limiting function of the female connector 11 and the male connector 31 during the insertion process, prevents circumferential displacement during insertion, and ensures insertion accuracy. On the other hand, the sliding fit method reduces the frictional resistance during insertion compared with the fixed connection, making the insertion operation smoother and less labor-intensive. At the same time, it can disperse the impact force during the insertion process, reduce component wear, and extend service life.

[0045] As a further implementation of this solution, the straight track 22, the spiral groove 23, and the first arc groove 24 are connected. The spiral groove 23 is spiral in shape, and the second arc groove 26 is arc in shape. Through the above arrangement, the connection design of the straight track 22, the spiral groove 23, and the first arc groove 24 provides a smooth channel for the sliding of the slide column 14 and the transmission of force. The spiral structure of the spiral groove 23 enables the slide column 14 to convert the axial insertion force into the circumferential force that drives the rotating drum 21 to rotate when it slides, realizing the linkage effect of "synchronous insertion and rotation". No additional rotational driving force is required, which meets the needs of rapid assembly. The arc structure of the second arc groove 26 is adapted to the sliding trajectory of the slide column 14. It can ensure that the slide column 14 can enter smoothly and lock, and can also provide a smooth guide for the sliding of the slide column 14 when unlocking, avoiding jamming. At the same time, the arc structure can disperse the stress when the slide column 14 contacts the second arc groove 26, preventing local wear.

[0046] As a further implementation of this solution, a cylindrical channel 25 is provided near the front end of the rotating cylinder 21. The first arc-shaped groove 24 is connected to the cylindrical channel 25. The cylindrical channel 25 extends out of the lower end of the rotating cylinder 21. The cylindrical channel 25 has an arc-shaped structure near the right end, which provides a channel basis for airflow control and slow reset during subsequent unlocking. The structure of the cylindrical channel 25 extending out of the lower end of the rotating cylinder 21 facilitates the installation and operation of the arc-shaped rod 37. The arc-shaped rod 37 can be maintained without disassembling other parts. The arc-shaped structure at the right end can prevent the arc-shaped rod 37 from getting stuck during sliding, ensuring the smooth movement of the arc-shaped rod 37. At the same time, it reduces the frictional wear between the arc-shaped rod 37 and the inner wall of the cylindrical channel 25, and improves the stability of the unlocking operation.

[0047] As a further implementation of this solution, an arc-shaped rod 37 is inserted inside the cylindrical channel 25, and a rubber sealing ring 38 is fixedly connected to the outside of the arc-shaped rod 37. The arc-shaped rod 37 and the rotating drum 21 are sealed by the rubber sealing ring 38. A stop post 36 is fixedly connected to the left side of the arc-shaped rod 37. The stop post 36 is embedded in the annular groove 27. Through the above settings, the sealing design of the rubber sealing ring 38 can effectively prevent external air, water vapor and other impurities from entering the cylindrical channel 25 and the first arc-shaped groove 24, avoiding blockage of the airflow channel or corrosion of internal components, and ensuring the stable operation of the airflow control mechanism. The embedded cooperation between the stop post 36 and the annular groove 27 plays a precise limiting role in the movement of the arc-shaped rod 37, preventing the arc-shaped rod 37 from deviating during the sliding process, ensuring that the arc-shaped rod 37 can accurately cooperate with the rotation of the rotating drum 21 to achieve the unlocking action, and at the same time improving the stability of the connection between the arc-shaped rod 37 and the rotating drum 21, and preventing the components from loosening during the unlocking process.

[0048] As a further implementation of this solution, a duckbill valve 28 is fixedly connected to the inner side of the cylindrical channel 25. An aerosol hole 29 is opened near the upper end of the duckbill valve 28, and the inner side of the duckbill valve 28 is connected to the aerosol hole 29. Through the above settings, the fixed connection between the second arc groove 26 and the cylindrical channel 25 realizes the integrated design of the unlocking mechanism and the airflow channel, which simplifies the overall structural layout. The opening of the annular groove 27 and its connection with the second arc groove 26 provide a stable space for the installation of the spring spring 32, ensuring the normal realization of the spring spring 32's elastic storage and reset functions. On the other hand, it can accurately control the airflow speed, allowing the airflow inside the cylindrical channel 25 to flow out slowly during unlocking and reset, reserving sufficient time for the slide column 14 and the spiral groove 23 to realign, avoiding component collision damage caused by the rapid rotation of the rotating drum 21, and improving disassembly safety and operational convenience.

[0049] As a further implementation of this solution, the spring 32 is embedded in the annular groove 27, and the outer periphery of the spring 32 is fixedly connected to the inner side of the annular groove 27. Through the above settings, the spring 32 is embedded and fixed on the outside, ensuring that it is firmly installed in the annular groove 27, avoiding displacement or falling off during elastic deformation and reset. The stable setting of the spring 32 can provide a continuous and stable elastic force, realize the automatic rotation and locking of the rotating drum 21 during installation, ensure the reliable cooperation between the sliding column 14 and the second arc groove 26, prevent the male and female heads from disengaging after connection, improve connection stability, and drive the rotating drum 21 to reset smoothly after unlocking, preparing for the next assembly without additional manual reset, simplifying the operation process.

[0050] As a further implementation of this solution, the male connector 31 has a insertion hole 33 on its inner side, and a rubber plug 34 is inserted into the insertion hole 33. A rubber pad 35 is fixedly connected to the rear end of the rubber plug 34, and the rear end of the rubber pad 35 fits against the front end of the female connector 11. Through the above settings, the assembly hole insertion hole 33 provides a precise installation and positioning space for the rubber plug 34, ensuring the assembly accuracy of the rubber plug 34 and the rubber pad 35. The fixed connection between the rubber plug 34 and the rubber pad 35, combined with the fit design between the rubber pad 35 and the front end of the female connector 11, can achieve a sealing effect simultaneously after the female connector 11 and the male connector 31 are inserted, effectively preventing moisture and impurities from entering the internal contact pins, ensuring the safety and stability of the electrical connection. Moreover, the structural design of the rubber plug 34 being inserted into the assembly hole insertion hole 33 gives the rubber pad 35 a modular characteristic that can be quickly disassembled and installed. When replacing it, there is no need to disassemble the main body of the male connector 31, making the operation convenient, reducing maintenance costs, and extending the overall service life of the connector.

[0051] Workflow: During installation, align the slot 12 at the front of the female connector 11 with the rear end of the male connector 31, while ensuring that the slide groove and guide block 13 on the left end of the male connector 31 are aligned. Insert the male connector 31 into the slot 12, slide the guide block 13 into the slide groove of the male connector 31, and insert the pin into the male connector 31. During this process, the sliding column 14 will enter the straight track 22. Since the straight track 22 is connected to the spiral groove 23, when the sliding column 14 contacts the spiral groove 23, the sliding column 14 will push the rotating drum 21 to rotate because the spiral groove 23 is spiral in shape. The rotating drum 21 is rotatably connected to the limiting ring 39. At this time, the rotating drum 21... 1. Rotating outside the male end 31, the rotating drum 21 drives the spring 32 to deform, and the spring 32 generates elastic force. The spring 32 moves inside the first arc groove 24, and the stop post 36 slides inside the annular groove 27. The setting of the stop post 36 and the annular groove 27 can prevent the rotating drum 21 and the male end 31 from rotating excessively. When the sliding post 14 enters the second arc groove 26, under the action of the spring 32 returning to its original shape, it will drive the rotating drum 21 to rotate until the sliding post 14 contacts the other end of the second arc groove 26. The cooperation between the sliding post 14 and the second arc groove 26 can prevent the rotating drum 21 and the male end 31 from separating, thus completing the installation.

[0052] During sealing, based on the above principle, during the assembly process between the male head 31 and the rotating cylinder 21, when the rubber gasket 35 is in contact with the front end of the female head 11, the sliding column 14 enters the second arc groove 26. The rubber gasket 35 plays the role of sealing between the rotating cylinder 21 and the male head 31, which can prevent water vapor or impurities from contacting the pin through the gap between the female head 11 and the male head 31, ensuring safe use. After multiple disassemblies and reassemblies, if it is found that the rubber gasket 35 is worn and needs to be replaced, the male head 31 is fixed, and the rubber gasket 35 is pulled backward. The rubber gasket 35 drives the rubber plug 34 to move away from the assembly hole insertion hole 33. Then, the rubber plug 34 fixed by other rubber gaskets 35 is aligned with the assembly hole insertion hole 33, and the rubber plug 34 is squeezed. The rubber plug 34 deforms and enters the assembly hole insertion hole 33 until the rubber gasket 35 is in contact with the male head 31.

[0053] During disassembly, rotating the drum 21 causes the arc-shaped rod 37 to slide inside the cylindrical channel 25. As the arc-shaped rod 37 slides away from the cylindrical channel 25, the rubber sealing ring 38 seals the air. At this time, external air enters the circulation hole 29 through the duckbill valve 28. The duckbill valve 28 restricts the flow of gas, allowing a large amount of external air to enter the cylindrical channel 25 from inside the duckbill valve 28, but making it difficult for air to flow out from inside the cylindrical channel 25 through the duckbill valve 28. This does not hinder quick installation. When the rotating drum 21 can no longer be rotated, the sliding column 14 contacts the other end of the second arc groove 26. After the rotating drum 21 is released, when the spring spring 32 resets the rotating drum 21, the opening diameter of the annular groove 27 is relatively small. This slows down the flow of the cylindrical channel 25 into the duckbill valve 28 through the annular hole 29. This not only allows time for the sliding column 14 to align with the spiral groove 23, but also eliminates the need for two-handed operation under limited space conditions, improving operational convenience. At the same time, it can prevent damage caused by the rapid rotation of the rotating drum 21 and the expansion of the male head 31.

[0054] 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.

Step 2: During the sealing process, when the male head (31) and the rotating cylinder (21) are assembled, the rubber pad (35) is attached to the front end of the female head (11), the sliding column (14) enters the second arc groove (26), the rubber pad (35) is assembled between the rotating cylinder (21) and the male head (31), the rubber pad (35) is pulled backward, the rubber pad (35) drives the rubber plug (34) to move away from the assembly hole (plug hole (33)), the rubber plug (34) fixed by another rubber pad (35) is aligned with the assembly hole (plug hole (33)), the rubber plug (34) is squeezed, the rubber plug (34) deforms and enters the assembly hole (plug hole (33)) until the rubber pad (35) and the male head (31) are attached; Step 3: During disassembly, rotate the drum (21), and the arc rod (37) slides inside the cylindrical channel (25). When the arc rod (37) slides away from the cylindrical channel (25), the rubber sealing ring (38) seals, and the external air will enter the circulation hole (29) through the duckbill valve (28). After the drum (21) can no longer be rotated, the sliding column (14) contacts the other end of the second arc groove (26), and the drum (21) is released. When the spring spring (32) resets the drum (21), the gas inside the cylindrical channel (25) enters the duckbill valve (28) through the circulation hole (29) and flows out.
