Description

Technical Field

[0001] This application relates to the technical field of insulating joints, and in particular to a quick-plug prefabricated insulating joint. Background Technology

[0002] An insulating joint is a component used to connect two power lines or data lines together for power or electronic data transmission. Commonly used cables include power cables, control cables, compensating cables, and shielded cables. A cable insulating joint is a component used to connect cables. Adjacent cables are plugged into the insulating joint to connect the two lines.

[0003] In low-voltage environments, the connection between two cables requires both convenience and stability. In existing technologies, two adjacent cables are plugged into the two ends of the connector and positioned by spring clips pressing against the cables. When disassembling, pulling the cable moves the spring clips to unlock the connection. Although this allows for quick installation and disassembly, the cables are prone to detachment under external force after connection. If the connection is achieved through spring clips and screws, disassembly becomes cumbersome. Thus, convenience of disassembly and connection stability are mutually exclusive. There is an urgent need for an insulating connector that is both easy to disassemble and provides a stable connection. Summary of the Invention

[0004] To simultaneously improve ease of assembly and disassembly as well as connection stability, this application provides a quick-plug prefabricated insulated connector.

[0005] This application provides a quick-plug prefabricated insulating connector, which adopts the following technical solution: A quick-plug prefabricated insulating connector includes an insulating body and two connecting mechanisms, wherein the connecting mechanisms include: The movable ring rotates and moves on the insulating body via a connecting component; The connector is located on the movable ring; A fixing component is installed on the cable and has an arc-shaped fixing groove. The fixing groove is slidably connected to the connector and forms an entry point for the connector to enter. A limiting component is installed on the insulating body and is used to limit the position of the moving ring; The sealing assembly is rotatably mounted on the movable ring and pressed against the fixed part for positioning under the action of elasticity; When the cable passes through the movable ring and is plugged into the insulating body, the driving fastener approaches the connector and the sealing assembly, causing the connector to slide through the entry point and be installed on the fixing groove, and the fastener presses against the sealing assembly. The connector rotates and slides on the fixing groove, causing the connector to first approach and then move away from the fastener, and finally abut against the end of the fixing groove away from the entry point for positioning.

[0006] By adopting the above technical solution, the cable is inserted and installed onto the insulating body through the movable ring. The movement of the cable drives the fixing part to approach the connector, so that the connector slides and is installed into the fixing groove through the entry point. The fixing part presses against the sealing component for positioning and sealing. The connector rotates and moves in the fixing groove, so that the connector first approaches the fixing part and then moves away from the fixing part. The rotation and movement of the connector drives the fixing part to first approach and then move away from the sealing component. Finally, the connector is pressed against the end of the fixing groove away from the entry point under the elastic force of the sealing component for positioning. The connector can be positioned under the elastic force of the sealing component. Therefore, the connector needs to be moved back and then rotated to unlock and disassemble. Thus, a stable connection of the insulating joint can be achieved with a simple structure, while improving the convenience of disassembly and assembly and the stability of the connection.

[0007] Optionally, the fixing groove includes a guide portion, a near portion, and a far portion of the same width connected in sequence. The guide portion is opened along the moving direction of the movable ring. The connector is slidably installed on the guide portion from the entry point and slidably installed on the near portion, so that the connector spirals closer to the fixing member. The connector is slidably installed on the far portion and spirals away from the fixing member, and finally presses against the far portion away from the near portion for positioning.

[0008] By adopting the above technical solution, the connector is slidably installed onto the guide part through the entry point. The guide part guides the cable when it is plugged into the insulation body. After the fixing part presses against the sealing assembly, the connector is rotated to move from the guide part to the near part. During the movement of the connector, the fixing part is driven to press against the sealing assembly. Then the connector moves from the near part to the far part. During this process, the sealing assembly pushes the movable ring and the connector away from the fixing part, that is, drives the connector away from the near part and closer to the far part, until the connector is pressed against the end of the far part away from the near part for positioning. The elasticity of the movable ring prevents the connector from moving to the near part for unlocking, and the connector abuts against the far part to prevent itself from rotating. This makes the connection process of the connector simpler and more stable, and further improves the convenience of disassembly and assembly and the stability of the connection.

[0009] Optionally, the connector includes a connecting sleeve and a connecting head. The connecting sleeve is disposed on the movable ring and fitted onto the outer wall of the fixing member for positioning and sealing. The connecting head is disposed on the inner wall of the connecting sleeve and is slidably connected to the fixing groove.

[0010] By adopting the above technical solution, during the process of inserting the cable into the insulation body, the connecting sleeve is fitted onto the outer wall of the fixing part to achieve positioning and sealing, preventing water from entering the connection between the cable and the insulation body. Twisting the connecting sleeve can drive the connector to slide on the fixing groove, realizing the rotation and movement of the connecting sleeve, which further improves the convenience of disassembly and assembly and the stability of the connection.

[0011] Optionally, the entry point is provided with a guide surface to facilitate the sliding installation of the connector onto the guide portion.

[0012] By adopting the above technical solution, the connector can be more easily slid into the fixing groove, making connection and disassembly more convenient.

[0013] Optionally, the limiting component includes: Two limiting rings are spaced apart and both are slidably sleeved on the insulating body, and the connecting component extends between the two limiting rings to achieve limiting; Two locking elements are respectively installed on the two limit rings and press against the insulating body to position the limit rings.

[0014] By adopting the above technical solution, the two limiting rings can limit the position of the connecting component and enable the connecting component to rotate and connect, allowing the connecting component to move and rotate on the insulating body. At the same time, the locking part can be unlocked to adjust the position of the two limiting rings, thereby realizing the position and movement of the connecting component, further improving the ease of disassembly and assembly and the stability of the connection.

[0015] Optionally, the connecting assembly includes multiple connecting blocks and multiple connecting screws. The multiple connecting blocks are arranged in a circumferential array around the axis of the movable ring and located inside the movable ring. The connecting screws pass through the movable ring and are threadedly connected to the connecting blocks, so that the connecting blocks are pressed against the inner wall of the movable ring for positioning.

[0016] By adopting the above technical solution, the connecting screw passes through the movable ring and is threadedly connected to the connecting block, so that the connecting block is pressed against the inner wall of the movable ring for positioning. The connecting block moves and rotates between the two limiting rings. At the same time, when it is necessary to remove the movable ring, the connecting screw can be turned to disengage from the connecting block.

[0017] Optionally, the fastener includes two fixing units and a fixing assembly for fixing the two fixing units. The two fixing units cooperate to clamp and position the cable, and each is fitted with a sealing ring that presses against the cable for positioning and sealing.

[0018] By adopting the above technical solution, the fixing component fixes the two fixing units together, so that the two fixing units push the sealing ring against the outer wall of the cable for positioning, thereby fixing the fixing component to the cable for positioning. At the same time, after the fixing component is unlocked, the two fixing units can be removed for replacement, which improves the convenience of disassembly of the insulation joint and the stability of the connection.

[0019] Optionally, the fixing component includes: The fixing screw passes through two fixing units; The fixing nut is threaded onto the fixing screw and, together with the head of the fixing screw, presses against the two fixing units for positioning.

[0020] By adopting the above technical solution, the fixing screw passes through two fixing units, and the fixing nut is threaded onto the fixing screw, so that the head of the fixing screw and the fixing nut press against the two fixing units respectively for positioning.

[0021] Optionally, the connector is a columnar structure, and the movable ring drives the connector to move on the fixed groove.

[0022] By adopting the above technical solution, the resistance encountered when the connector moves is reduced, making disassembly and installation more convenient, and further improving the ease of disassembly and assembly and the stability of the connection.

[0023] Optionally, a positioning part is provided at one end of the far-away part away from the near-away part, and the connector is pressed against the far-away part and, after rotation, snapped onto the positioning part for positioning.

[0024] By adopting the above technical solution, the connector is snapped onto the positioning part for positioning, thereby preventing the connector from moving along the axis of the fixing part and unlocking it. The movable ring needs to rotate to disengage the connector from the positioning part, and then the movable ring needs to rotate and move to unlock it, thereby further improving the ease of disassembly and assembly and the stability of the connection.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The connector is slidably installed onto the fixing groove, so that the fixing part presses against the sealing component for positioning and sealing. The connector rotates and moves on the fixing groove, so that the connector first moves closer to and then away from the fixing part. The rotation and movement of the connector drives the fixing part to first move closer to and then away from the sealing component. Finally, under the elastic force of the sealing component, the connector is pressed against the end of the fixing groove away from the entry point for positioning. The connector can be positioned under the elastic force of the sealing component, so the connector needs to be moved back and then rotated to unlock and disassemble. Thus, a stable connection of the insulating joint can be achieved with a simple structure, while improving the convenience of disassembly and assembly and the stability of the connection.

[0026] 2. The connector is slidably installed onto the guide section. The guide section guides the cable when it is plugged into the insulation body. After the fixing member presses against the sealing assembly, the connector is rotated to move from the guide section to the near section. During the movement of the connector, the fixing member is driven to squeeze the sealing assembly. Then the connector moves from the near section to the far section. During this process, the sealing assembly pushes the movable ring and the connector away from the fixing member, that is, drives the connector away from the near section and closer to the far section, until the connector is positioned against the end of the far section away from the near section. The elasticity of the movable ring prevents the connector from moving to the near section to unlock, and the connector abuts against the far section to prevent itself from rotating. This makes the connection process simpler and more stable, and further improves the ease of disassembly and assembly and the stability of the connection. Attached Figure Description

[0029] The following provides a further detailed description of this application.

[0030] This application discloses a quick-plug prefabricated insulated connector.

[0031] Reference Figures 1-3 The quick-plug prefabricated insulated connector includes an insulating body 12 and two connecting mechanisms 2. The two connecting mechanisms 2 are located at both ends of the insulating body 12 and facilitate connection with two adjacent cables 11, making the connection of the cables 11 more stable. This enables the two cables 11 to be connected or disconnected stably and conveniently in a low-voltage environment.

[0032] The insulating body 12 includes a fiberglass shell 13 and grounding terminals 14. Two grounding terminals 14 are provided and fixedly installed inside the fiberglass shell 13 to achieve grounding. The cable 11 includes a battery core 15 and an outer sheath 16 covering the battery core 15. Two adjacent cables 11 are plugged into both ends of the fiberglass shell 13, so that the two battery cores 15 are connected by abutting against each other. Meanwhile, the two battery cells 15 are connected to the two grounding terminals 14 respectively to achieve grounding.

[0033] Reference Figures 2-5 The insulating body 12 is in the form of a circular tube. The connecting mechanism 2 includes a movable ring 21, a limiting component 3, a fixing component 7, a connecting component 22, and a sealing component 4. The movable ring 21 rotates and moves on the outer wall of the insulating body 12 through the connecting component 5. The axes of the movable ring 21 and the insulating body 12 coincide.

[0034] The limiting component 3 includes two limiting rings 31 and two locking members 32. The limiting rings 31 are coaxially slidably sleeved on the outer wall of the insulating body 12, and the two limiting rings 31 are spaced apart along the axis of the insulating body 12. The two locking members 32 are respectively disposed on the two limiting rings 31 and press against the insulating body 12 to position the limiting rings 31. The locking member 32 is a locking screw, which is threadedly connected to the limiting ring 31 and presses against the insulating body 12 for positioning. At the same time, the head of the locking member 32 is located inside the limiting ring 31.

[0035] The connecting assembly 5 includes multiple connecting blocks 51 and multiple connecting screws 52. The multiple connecting blocks 51 are arranged in a circumferential array around the axis of the insulating body 12 and are located inside the movable ring 21. The connecting screws 52 pass through the movable ring 21 and are threadedly connected to the connecting blocks 51, so that the connecting blocks 51 are pressed against the inner sidewall of the movable ring 21 for positioning. The connecting blocks 51 are arc-shaped and coaxially arranged with the movable ring 21. The connecting blocks 51 are located between two limiting rings 31, realizing the rotation and movement of the movable ring 21. The movement of the movable ring 21 drives the connecting blocks 51 to abut against one of the limiting rings 31 for positioning.

[0036] Reference Figures 2-6 The fixing member 7 is set on the outer wall of the cable 11. The axis of the fixing member 7 and the insulation body 12 coincides. The fixing member 7 includes two fixing units 71 and a fixing assembly 8 that fixes the two fixing units 71. The two fixing units 71 cooperate to clamp on the cable 11 for positioning, and each is snapped with a sealing ring that presses against the outer wall of the cable 11 for positioning and sealing.

[0037] The fixing component 8 includes a fixing screw 81 and a fixing nut 82. The fixing screw 81 passes through two fixing units 71, and the fixing nut 82 is threaded onto the fixing screw 81. The head of the fixing screw 81 and the fixing nut 82 press against the two fixing units 71 for positioning. The connecting piece 22 is set on the end of the movable ring 21 away from the two limiting rings 31. An arc-shaped fixing groove 6 is opened on the outer wall of the fixing unit 71 for the connecting piece 22 to slide.

[0038] The fixing groove 6 includes a guide portion 61, a near portion 62, and a far portion 63 of the same width that are connected in sequence. That is, the guide portion 61 and the far portion 63 are respectively connected to the two ends of the near portion 62. The guide portion 61 is opened along the axis of the fixing member 7 and passes through the end of the fixing member 7 near the connecting component 5. The end of the guide portion 61 near the connecting component 5 forms an entry point 64 for the connecting member 22 to slide into.

[0039] Both the proximal portion 62 and the distal portion 63 are spiral-shaped, and their axes coincide with the axis of the fixing member 7. The proximal portion 62, from the guide portion 61 to the distal portion 63, spirals away from the movable ring 21. The distal portion 63 and the proximal portion 62 are mirror-symmetrically arranged about their connection point. The connector 22 includes a connecting sleeve 23 and a connector head 24. The connecting sleeve 23 is coaxially disposed on the end of the movable ring 21 away from the connecting assembly 5. The inner diameter of the connecting sleeve 23 is larger than the outer diameter of the fixing member 7. The connecting sleeve 23 is fitted onto the two fixing units 71 for positioning and sealing. The connector head 24 is fixedly installed on the inner side wall of the connecting sleeve 23. The connector head 24 is cylindrical and slides in connection with the fixing groove 6. A guide surface is provided at the entry point 64 to facilitate the connector head 24 entering the guide portion 61.

[0040] When the connector 24 moves to the connection between the guide part 61 and the proximity part 62, the two fixed units 71 press against the sealing ring 42 for positioning. The connector 24 moves on the proximity part 62 and approaches the distance part 63, so that the sealing ring 42 continues to approach the rotating disk 41 and is squeezed. Then the connector 24 moves on the distance part 63 and away from the proximity part 62, and the sealing ring 42 moves away from the rotating disk 41 until the connector 24 presses against the end of the distance part 63 away from the proximity part 62, that is, the connector 24 presses against the end of the fixing groove 6 away from the entry point 64 for positioning.

[0041] An arc-shaped positioning part 65 is provided at one end of the far-away part 63 away from the near-away part 62 around the axis of the fixing member 7. When the connector 24 is pressed against the end of the far-away part 63 away from the near-away part 62, the rotating movable ring 21 drives the connector 24 to be snapped into the positioning part 65 for positioning. Thus, when unlocking, it is necessary to first rotate the movable ring 21 and then push the movable ring 21 to move and rotate before unlocking can be achieved, further reducing the risk of unlocking, while improving the convenience of disassembly and assembly and the stability of connection.

[0042] An installation ring 25 is coaxially arranged on the inner wall of the movable ring 21 and on the outer side of the insulating body 12. The inner diameter of the installation ring 25 is smaller than the outer diameter of the insulating body 12 and larger than the outer diameter of the cable 11. The sealing component 4 is rotatably arranged on the movable ring 21 and is pressed against the end of the fixing member 7 near the movable ring 21 for positioning under the action of elasticity.

[0043] The sealing assembly 4 includes a rotating disk 41 and a sealing ring 42. The rotating disk 41 is coaxially rotatably mounted on the side wall of the mounting ring 25 away from the insulating body 12. The sealing ring 42 is coaxially fixedly mounted on the side wall of the rotating disk 41 away from the mounting ring 25. The sealing ring 42 is made of rubber material and is used for sealing.

[0044] The movable ring 21, connecting sleeve 23, connector 24, and sealing assembly 4 are pushed close to the fixing member 7, causing the connector 24 to slide and install onto the guide part 61 through the entry point 64. The connector 24 moves to the connection between the guide part 61 and the proximity part 62, and the sealing ring 42 is pressed against the fixing member 7 for positioning. The movable ring 21 is pushed to move, causing the connector 24 to move and rotate on the proximity part 62. Then, the connector 24 moves and rotates on the distance part 63 until the connector 24 is pressed against the end of the distance part 63 away from the proximity part 62 for positioning under the elastic force of the sealing ring 42. This also drives the connecting sleeve 23, movable ring 21, and mounting ring 25 to rotate, causing the mounting ring 25 and the rotating disk 41 to rotate and first squeeze the sealing ring 42 and then move away from the sealing ring 42. Finally, the sealing ring 42 presses against the fixing member 7 to achieve a seal, thus connecting the two cables 11.

[0045] When cable 11 needs to be disassembled, the movable ring 21 needs to be rotated and then moved back, so that the connector 24 moves out after passing through the distance part 63, the proximity part 62 and the guide part 61 in sequence. Unlocking requires the movable ring 21 to rotate and move. If the movable ring 21 only rotates, the distance part 63 and the positioning part 65 can block the rotation of the movable ring 21. If the movable ring 21 moves, the elasticity of the sealing ring 42 and the positioning part 65 can block the movement of the movable ring 21, thereby enabling quick disassembly and connection, while improving the convenience of disassembly and assembly and the stability of connection.

[0046] The working principle of this application embodiment is as follows: The cable 11 is plugged into the inner wall of the insulating body 12. The movable ring 21 is pushed close to the fixing part 7, so that the connector 24 slides and is installed on the guide part 61. The connector 24 passes through the near part 62 and the far part 63 in sequence until the connector 24 is pressed against the end of the far part 63 away from the near part 62 under the elastic force of the sealing ring 42. The movable ring 21 is rotated so that the connector 24 is snapped into the positioning part 65 for positioning, thereby connecting the two cables 11.

[0047] When cable 11 needs to be disassembled, rotate the movable ring 21 and then push the movable ring 21 back, so that the connector 24 moves out after passing through the positioning part 65, the distance part 63, the proximity part 62 and the guide part 61 in sequence. This means that unlocking requires the movable ring 21 to rotate and move. If the movable ring 21 only rotates, the distance part 63 blocks the rotation of the movable ring 21. If the movable ring 21 moves, the elasticity of the sealing ring 42 can block the movement of the movable ring 21, thereby enabling quick disassembly and connection, while improving the convenience of disassembly and assembly and the stability of the connection.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
