Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to a fast-installation and disassembly safety energy storage system connection device. Background Technology

[0002] In a safe energy storage battery system, male and female connectors ensure a secure and safe connection between the battery module and external devices or other units. Their structure consists of two parts: a male connector with pins or prongs, and a female connector with corresponding holes or slots. The two work together to achieve an electrical connection. For safety, connectors are often made of high-temperature resistant and corrosion-resistant insulating materials, while the internal conductive parts are made of highly conductive metal materials. The design also considers preventing mis-connection, typically using different shapes or colors to avoid the risks associated with incorrect connections. The connection process is relatively simple. With the power off, the user inserts the male connector into the female connector, ensuring it is fully inserted and securely connected. Some connectors also have locking or snap-fit ​​devices to prevent them from falling off during use. After connection, it is recommended to test and confirm to ensure good contact and reliability. When disassembling, follow the reverse order to avoid damaging the connector or causing a short circuit. As disclosed in the patent announcement CN217334481U, an embedded mobile energy storage device battery connection connector is provided between the lower and upper housings. A connecting post is fixedly connected to the bottom of the connector, extending through to the bottom of the lower housing. A wire is fixedly connected to the top of the connector, extending through to the top of the upper housing. An upper connecting piece is fixedly connected to the side of the upper housing, and a lower connecting piece is fixedly connected to the side of the lower housing. Through the cooperation of the upper and lower connecting pieces and the fixing mechanism, the connector can be disassembled promptly if damaged. However, the above technical solution mainly relies on the fixing mechanisms on the left and right sides to secure the upper and lower housings. For cylindrical male and female connectors, this technical solution is difficult to apply successfully. Traditional solutions still rely on rotating the nut on the male end and tightening it with the thread on the female end, or on the male and female ends having interlocking elastic buckles and grooves that produce a "click" sound when inserted into place. The locking mechanism, particularly the threaded connection, is prone to loosening, especially under significant vibration or impact. Furthermore, the connection between the snap-fit ​​and the groove relies on the properties of the elastic material. Prolonged use or extreme environments (such as high temperature, low temperature, or humidity) can cause the elastic material to age and lose its elasticity, reducing connection reliability. Separation is also relatively difficult, especially after tight connections or snap-fit ​​deformation, requiring considerable force and increasing operational difficulty and risk. This could even damage the snap-fit ​​or groove, affecting subsequent male and female connector connections. Summary of the Invention

[0003] The purpose of this invention is to provide a fast-installing and uninstalling safe energy storage system connection device. The conductive terminal of the female connector is inserted into the terminal fixing seat of the male connector. The internal threaded sleeve on the female connector and the external threaded sleeve on the male connector are tightened and fixed until the female connector and the male connector are initially threaded. At this time, the rib-type connecting seat on the rear male panel is close to the square protruding corner seat on the outer wall of the female connector. The self-spring-loaded column fastening assembly makes the first oblique internal thread column and the second oblique internal thread column at the top of the rib-type connecting seat concentric and coaxial. The oblique internal thread columns one and two can be connected by bolts, thereby completely locking the male and female connectors and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick-installation and disassembly safety energy storage system connection device, comprising a rear male panel, a male connector with a terminal fixing seat installed inside the rear male panel, and a female connector disposed on one side of the male connector. The female connector has a conductive terminal installed inside for insertion and mating with the terminal fixing seat. An internally threaded sleeve is rotatably installed at one end of the female connector near the male connector. An external thread is installed on the outer wall of the rear male panel near the female connector for threaded mating with the internally threaded sleeve. The female connector has several equally spaced square-mouth protruding corner seats fixed on its arc-shaped outer wall. The lower end of the square-mouth protruding corner seat is provided with a stepped portion and contacts the outer wall of the internal threaded sleeve. A rib-type connecting seat is installed on the outer wall of the rear male panel near the square-mouth protruding corner seat, and a second oblique internal thread post is installed at the top of the rib-type connecting seat. A self-spring-loaded post fastening assembly is installed on the outer wall of the square-mouth protruding corner seat, and an oblique internal thread post one is installed at the movable end of the self-spring-loaded post fastening assembly for bolting and engaging with the second oblique internal thread post.

[0005] Preferably, a sealing ring is embedded on the inner wall of the internal threaded sleeve, and the inner side of the sealing ring is in contact with the outer wall of the female connector.

[0006] Preferably, a recess is provided on the outer wall of the square-mouth protruding corner seat near the rib plate type connecting seat, and the self-spring-loaded column fastening assembly is installed in the recess. A total of three square-mouth protruding corner seats are provided.

[0007] Preferably, the self-elastic column fastening assembly includes a support shaft fixed inside the recess, swing arms fitted at both ends of the support shaft surface, and a flat plate integrally formed between the two swing arms. The inclined internal threaded column is fixed at the lower end of the flat plate, and a torsion spring is installed at one end of the support shaft surface to prevent the swing arms, the flat plate, and the inclined internal threaded column from swinging downward around the support shaft.

[0008] Preferably, one end of the torsion spring extends into the interior of the flat plate, and the other end of the torsion spring extends into the interior of the square-mouthed convex corner seat through the recess.

[0009] Preferably, a secondary right-angle locking arm is installed on the outer wall of each of the two swing arms on the side that is far apart. A cylindrical locking cavity for the secondary right-angle locking arm to be inserted is provided on the front and rear outer walls of the square-mouth convex corner seat. A round hole concentric with the inclined internal thread column is provided on one side of the top of the flat plate.

[0010] Preferably, the secondary right-angle locking arm includes an I-shaped shaft rotatably mounted inside the swing arm, a U-shaped head mounted at one end of the I-shaped shaft, and a round handle hinged inside the U-shaped head.

[0011] Preferably, the lower surface of the rib-type connector is provided with an arc-shaped cutting groove, the diameter of which is equal to the outer diameter of the internal threaded sleeve.

[0012] Preferably, a hollow sleeve is fixed at one end of the female connector near the male connector, and a gap is provided between the external threaded sleeve and the male connector for the hollow sleeve to be inserted into. Three rectangular ribs are integrally formed in an annular equidistant array on the outer wall of the hollow sleeve, and a rectangular slot is provided on the inner wall of the external threaded sleeve to engage with the rectangular ribs.

[0013] Preferably, a copper sheet is installed on the inner wall of the external threaded sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This quick-installation and disassembly safe energy storage system connection device is provided with a structure in which a rear male panel, a male plug, an external threaded sleeve, a ribbed connector, a female plug, an internal threaded rotating sleeve, a square-mouth convex corner seat, and a self-spring-loaded column fastening assembly cooperate with each other. The conductive terminal of the female plug is inserted into the terminal fixing seat of the male plug, and the internal threaded rotating sleeve on the female plug and the external threaded sleeve on the male plug are tightened and fixed until the female plug and the male plug are initially threaded. At this time, the ribbed connector on the rear male panel is close to the square-mouth convex corner seat on the outer wall of the female plug, and the self-spring-loaded column fastening assembly makes the first oblique internal thread post and the second oblique internal thread post at the top of the ribbed connector concentric and coaxial. The oblique internal thread posts one and two can be connected by bolts, thereby completely locking the male and female plugs and ensuring the stability of the conductive and mechanical connection. The connection process is simplified through reasonable design, reducing the difficulty of operation. In terms of service life, the multi-level locking mechanism of the structure effectively extends the working cycle of the connector and reduces the maintenance frequency. The tightening of the internal threaded sleeve and the external threaded sleeve first brings the male and female connectors together, eliminating manufacturing tolerances and assembly gaps, allowing the conductive terminals to achieve initial good contact, and providing a stable base platform for subsequent rigid locking. After the initial thread is tightened, the ribbed connector on the male faceplate is close to the square protruding corner seat on the outer wall of the female connector, achieving precise circumferential and radial positioning. This effectively prevents the connector from rotating or shifting laterally when subjected to vibration or torsional loads (such as cable pulling), ensuring that the conductive terminals always remain in the best alignment and contact state. The self-springing post fastening assembly ensures that the first inclined internal thread post and the second inclined internal thread post at the top of the ribbed connector are automatically concentric and coaxial. By tightening these two posts through the bolt, a strong axial tension force is generated, which acts directly, rigidly and evenly on the entire connector interface, tightly "pressing" the male and female connectors together. Secondly, the rotation and tightening operation of the internal threaded swivel and the external threaded sleeve is simple and intuitive, requiring no special tools. It can quickly bring the male and female connectors together roughly, laying the foundation for subsequent precise positioning. This is much easier than directly aligning the bolt holes precisely. After the initial thread pre-tightening is in place, the first inclined internal threaded post automatically adjusts to a position concentric and coaxial with the second inclined internal threaded post, eliminating the tedious step of the operator visually aligning the two small-diameter threaded posts. This significantly reduces the difficulty and time consumption of operation, especially in installation positions where it is difficult to observe. Users do not need to repeatedly adjust or forcefully tighten multiple bolts. They only need to operate according to the designed sequence to complete the connection, which greatly improves work efficiency. Finally, the multi-layered locking mechanism reduces mechanical stress concentration at a single connection point, lowering the risk of fatigue damage to threaded components. The tightening of the internal threaded swivel and the external threaded sleeve provides continuous mechanical pressure, effectively preventing loosening caused by vibration or temperature changes and extending the stability of the connection. The fit between the ribbed connector and the oblique internal threaded posts one and two enhances the rigidity and fatigue resistance of the overall structure, reducing wear caused by repeated insertion and removal. In addition, the self-adjusting function of the self-spring-loaded post fastening assembly buffers mechanical shocks and vibrations while also reducing wear between the threads and the contact surface, thereby extending the service life of the connector.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1 to 4 The present invention includes a rear male panel 1, a male connector 2 with a terminal fixing seat installed inside the rear male panel 1, and a female connector 3 disposed on one side of the male connector 2. The female connector 3 has conductive terminals installed inside for insertion and mating with the terminal fixing seat. An internally threaded sleeve 5 is rotatably mounted on one end of the female connector 3 near the male connector 2. An externally threaded sleeve 4 for threaded mating with the internally threaded sleeve 5 is installed on the outer wall of the rear male panel 1 near the female connector 3. A fixed arc-shaped outer wall of the female connector 3 is also provided. There are several equally spaced square-mouth protruding corner seats 6. The lower end of the square-mouth protruding corner seat 6 is provided with a stepped part and contacts the outer wall of the internal threaded rotating sleeve 5. A rib plate type connecting seat 9 is installed on the outer wall of the rear male panel 1 near the square-mouth protruding corner seat 6. The top of the rib plate type connecting seat 9 is installed with a second oblique internal thread post 10. A self-spring-loaded post fastening assembly 7 is installed on the outer wall of the square-mouth protruding corner seat 6. The movable end of the self-spring-loaded post fastening assembly 7 is equipped with an oblique internal thread post 8 for bolting and engaging with the second oblique internal thread post 10. The male connector 2 integrates a terminal fixing base and provides a primary guide structure to guide the insertion of the female terminal of the female connector 3. The external thread sleeve 4 is designed to be separate from the terminal base to ensure that the thread preload does not interfere with the terminal alignment. The overall structure optimizes the terminal protection and heat dissipation path. The internal insulation structure of the female connector 3 precisely fixes the female terminal, ensuring full contact with the terminal block in the male connector 2; A sealing ring 501 is embedded on the inner wall of the internal threaded swivel 5. The inner side of the sealing ring 501 is in contact with the outer wall of the female connector 3. The internal threaded swivel 5 is rotatably installed at one end of the female connector 3, and the sealing ring 501 improves the sealing and protection effect between the contact surfaces of the female connector 3 and the internal threaded swivel 5.

[0019] Example 2, based on Example 1, is... Figure 5 , Figure 6 and Figure 7 As shown, a recess 601 is provided on the outer wall of the square-mouth protruding corner seat 6 near the rib plate type connecting seat 9, and a self-spring-loaded column fastening assembly 7 is installed in the recess 601. A total of three square-mouth protruding corner seats 6 are provided. The self-elastic column fastening assembly 7 includes a support shaft 701 fixed inside the recess 601, swing arms 702 fitted at both ends of the surface of the support shaft 701, and a flat plate 704 integrally formed between the two swing arms 702. An oblique internal threaded column 8 is fixed at the lower end of the flat plate 704. A torsion spring 703 is installed at one end of the surface of the support shaft 701 to prevent the swing arms 702, the flat plate 704, and the oblique internal threaded column 8 from swinging downward around the support shaft 701. One end of the torsion spring 703 extends into the interior of the flat plate 704, and the other end of the torsion spring 703 extends through the recess 601 into the interior of the square-mouth convex corner seat 6. Two secondary right-angle locking arms 705 are installed on the outer walls of the two swing arms 702 on their opposite sides. Cylindrical locking cavities 602 are provided on the front and rear outer walls of the square-mouthed convex corner seat 6 for the secondary right-angle locking arms 705 to be inserted. When using the inclined internal threaded column 8, the operator manually moves the flat plate 704 and the inclined internal threaded column 8 downwards, causing the flat plate 704 and the inclined internal threaded column 8 to drive the swing arms 702 to deflect around the support shaft 701. At this time, the torsion spring 703 is subjected to force and deforms until... The oblique internal thread post 8 and the oblique internal thread post 10 at the top of the rib plate type connecting seat 9 are in a concentric state. Then, the secondary right angle locking arm 705 is operated so that the handle end of the secondary right angle locking arm 705 is inserted into the cylindrical cavity 602 on the outer wall of the square convex corner seat 6. At this time, the cylindrical cavity 602 and the secondary right angle locking arm 705 are used to lock the position of the flat plate 704 and the oblique internal thread post 8, which makes it convenient for the staff to perform the knob operation of the oblique internal thread post 8 and the oblique internal thread post 10. The top side of the flat plate 704 is provided with a round hole concentric with the inclined internal thread post 8. The secondary right angle locking arm 705 includes an I-beam shaft rotatably installed inside the swing arm 702, a U-shaped head installed at one end of the I-beam shaft, and a round handle hinged inside the U-shaped head. When separating the oblique internal thread post 8 and the oblique internal thread post 10, the bolts between the oblique internal thread post 8 and the oblique internal thread post 10 are unscrewed, and the handle of the secondary right angle locking arm 705 is removed from the cylindrical cavity 602. At this time, the torsion spring 703 is no longer restricted by external force and deforms and resets. That is, the torsion spring 703 forces the flat plate 704, the internal thread rotating sleeve 5, and the swing arm 702 to return to their initial positions, so as to facilitate the next connection of the male connector 2 and the female connector 3, and does not hinder the connection of the male connector 2 and the female connector 3.

[0020] Example 3, based on Example 1, is... Figure 8 and Figure 9 As shown, the lower surface of the rib-type connector 9 is provided with an arc-shaped cutting groove 901. The diameter of the arc-shaped cutting groove 901 is equal to the outer diameter of the internal threaded sleeve 5. After the male connector 2 and the female connector 3 are connected, the lower surface of the rib-type connector 9 contacts the outer wall surface of the internal threaded sleeve 5 through the arc-shaped cutting groove 901. At this time, the rib-type connector 9 is concentrically fitted with the internal threaded sleeve 5 through the arc-shaped cutting groove 901. A hollow sleeve 11 is fixed at one end of the female connector 3 near the male connector 2. A gap 401 is provided between the external threaded sleeve 4 and the male connector 2. The gap 401 is used for the hollow sleeve 11 to be inserted into the gap. The outer wall of the hollow sleeve 11 has three rectangular ribs 1101 integrally formed in an annular equidistant array. The inner wall of the external threaded sleeve 4 is provided with a rectangular slot 403 that engages with the rectangular ribs 1101. A gap 401 is formed between the external threaded sleeve 4 and the male connector 2 to allow the hollow sleeve 11 to enter. At the same time, when the male connector 2 and the female connector 3 are pulled closer by the external threaded sleeve 4 and the internal threaded rotating sleeve 5, the rectangular slot 403 and the rectangular ribs 1101 achieve the guiding purpose to avoid positional displacement during the pre-tightening operation. A copper sheet 402 is installed on the inner wall of the external threaded sleeve 4. The copper sheet 402 acts as a metal skeleton to evenly diffuse the axial tensile force generated by tightening to the outer edge of the external threaded sleeve 4, avoiding stress concentration at the root of the thread and causing plastic cracking. In addition, the copper sheet 402 can enhance the overall electromagnetic shielding performance of the connector and reduce interference to surrounding equipment during high current switching.

[0021] In this embodiment, during use, first, hold the female connector 3 and align its conductive terminals with the opening of the terminal fixing seat of the male connector 2. Smoothly push the female connector 3 along the axial direction to allow the female conductive terminals to initially enter the male terminal fixing seat. At this point, the connection is in a loose state and not locked. Rotate the internal threaded sleeve 5 on the female connector 3 to engage with the external threaded sleeve 4 on the male connector 2. Continue rotating the internal threaded sleeve 5 to gradually pull the male connector 2 and female connector 3 closer together. During this process, eliminate the gap between the mating surfaces, allowing the conductive terminals to achieve initial reliable contact. Then, pull the ribbed connector 9 on the rear male panel 1 to tighten the square protruding corner seat 6 on the outer wall of the female connector 3, tightening until the resistance increases significantly or the preset initial pre-tightening position is reached. At this point, the male connector 2 and female connector 3 achieve initial mechanical fixation and electrical connection. It should be noted that the self-spring-loaded post fastening assembly 7 is in its initial position and does not... This will hinder the tightening of the male connector 2 and the female connector 3. When the initial thread pre-tightening is in place, the operator manually moves the inclined internal thread post 8 downwards, causing the self-spring-type post fastening component 7 to activate. At this time, the inclined internal thread post 8 deflects towards the central axis of the female connector 3 until the inclined internal thread post 8 and the inclined internal thread post 10 at the top of the rib plate type connecting seat 9 are concentric and coaxial. Take out the appropriate size bolt and screw its lower end into the inclined internal thread post 8 and the inclined internal thread post 10. The tightening of the bolt generates a strong axial tensile force, which further rigidly tightens the inclined internal thread post 8 and the inclined internal thread post 10. Tighten until the specified hand torque is reached or the bolt is fully in place to ensure that the connection is absolutely firm. At this time, the male connector 2 and the female connector 3 are fully locked through the triple mechanism of initial thread pre-tightening, square convex corner seat 6, anti-torsional load of rib plate type connecting seat 9 and bolt axial rigid locking, and are in the most reliable state. When separating the male connector 2 and the female connector 3, confirm that the energy storage power supply system has been safely de-energized and the disconnection conditions are met. Unscrew the bolts on the inclined internal thread post 1 8 and the inclined internal thread post 2 10 to release the rigid axial locking force. After the bolts are removed, the self-spring-loaded post fastening assembly 7 loses its locking force, causing the inclined internal thread post 1 8 to automatically return to its initial position, thus disengaging the inclined internal thread post 1 8 from the coaxial constraint state with the inclined internal thread post 2 10, ensuring that there is no longer any mechanical interference between the two. Rotate the internal threaded sleeve 5 on the female connector 3 in the opposite direction, so that the internal threaded sleeve 5 and the external threaded sleeve 4 of the rear male faceplate 1 are aligned. Gradually loosen the screws. During the loosening process, the preload between the male connector 2 and the female connector 3 is gradually released, and the ribbed connector 9 and the square-mouth convex corner seat 6 also begin to separate. Loosen the screws until the internal threaded sleeve 5 is completely disengaged from the external threaded sleeve 4 and is noticeably loose. Hold the female connector 3 and the male connector 2 firmly with both hands and apply a pulling force smoothly and straight along the axial direction to pull the female connector 3 out of the male connector 2. When pulling out, overcome the residual friction between the conductive terminals and keep the movement smooth to avoid shaking that could damage the terminals or structure. After the male connector 2 and the female connector 3 are completely separated, check the condition of the terminals.
