Description

Technical Field

[0001] This utility model relates to the technical field of connector devices, specifically a cable protection pipe connection connector. Background Technology

[0002] Cable protection pipes, also known as cable conduits, power cable conduits, cement cable conduits, power ducts, and power cable protection pipes, are mainly installed at the intersection of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and wire ropes. When two sections of cable protection pipes are connected, a joint is required at the connection point.

[0003] A search revealed a cable protection pipe connector device with application number 201921974625.2. This device uses a double-fixing method, both internally and externally, to ensure a more secure installation of the connector body onto the cable protection pipe. The embedded connector is connected to the inside of the cable protection pipe via a telescopic protrusion and groove, further securing the embedded connector within the pipe and preventing breakage at the connection point. However, this device has a large gap at the connection point, allowing water to easily seep into the pipe in outdoor environments, potentially causing a short circuit at the cable interface. Furthermore, installation requires loosening multiple nuts and bolts before securing the connector, a time-consuming and labor-intensive process with low installation efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cable protection pipe connection joint to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable protection pipe connector, comprising a first cable body and a second cable body, wherein a first sealing cap and a male connector are respectively fitted onto the outer surface of the first cable body, a limiting ring is fitted inside the male connector, limiting holes are formed on both sides of the limiting ring, a sealing cylinder is connected to one side of the limiting ring, and a rack is connected inside the sealing cylinder, wherein a second sealing cap and a female connector are respectively fitted onto the outer surface of the second cable body, a pressure plate is connected to one end of the female connector, a fixing seat is connected to one side inside the female connector, a bidirectional screw is installed in the middle of the fixing seat through a limiting block, a gear is connected to the top of the bidirectional screw, a clamping block is threadedly connected to the outer surface of the bidirectional screw, and the clamping block is slidably connected to the fixing seat.

[0006] Furthermore, the second cable body is movably connected to the second sealing cover and the female connector, respectively, and the first cable body is movably connected to the first sealing cover and the male connector, respectively.

[0007] By adopting the above technical solution, the workers first pass the second cable body through the second sealing cover and the female connector respectively, and let the copper core of the second cable body enter the fixing seat. By rotating the second sealing cover and cooperating with the clamping claw, the female connector is fixed on the second cable body, so that the female connector and the second cable body are connected into a whole, which facilitates subsequent installation (the connection method of the first cable body with the first sealing cover and the male connector has the same function).

[0008] Furthermore, both the inner side of the male connector and the outer side of the female connector are threaded, and the male connector and the female connector are threadedly connected.

[0009] By adopting the above technical solution, the staff pushes the male connector towards the female connector. When the internal thread of the male connector corresponds to the external thread of the female connector, the male connector is rotated to connect the male connector and the female connector into a whole through the threads, thereby sealing the fixed seat.

[0010] Furthermore, both the male connector and the female connector are connected to clamping claws, and the clamping claws are made of elastic plastic.

[0011] By adopting the above technical solution, the operator rotates the first sealing cover, causing it to rotate and move towards the male connector. The first sealing cover presses against the clamping claws, causing the clamping claws to retract and fit tightly against the outside of the first cable body, thereby fixing the first cable body. Through the cooperation of the clamping claws and the first sealing cover, the first cable body and the male connector are connected as a whole, preventing water from seeping into the interface from the male connector side (the connection method between the second sealing cover and the female connector is the same as the connection method between the first sealing cover and the male connector).

[0012] Furthermore, the pressure plate is slidably connected to the limiting hole, and the limiting ring is rotatably connected to the male connector.

[0013] By adopting the above technical solution, when the operator rotates the male connector, the pressure plate cooperates with the limiting hole to limit the limiting ring, preventing the limiting ring from rotating and causing the sealing cylinder to drive the rack to rotate, which would collide with the gear and cause interference, thus affecting the practicality of the device.

[0014] Furthermore, the gear meshes with the rack.

[0015] By adopting the above technical solution, the staff aligns the pressure plate with the limiting hole and pushes the male connector towards the female connector. During the pushing process, the sealing cylinder drives the rack to move. Through the meshing of the rack and gear, the rack drives the gear to rotate. Under the drive of the gear, the bidirectional screw drives the two clamping blocks to move in opposite directions, clamping and pressing the copper core of the first cable body and the copper core of the second cable body, fixing the first cable body and the second cable body in the fixed seat at the same time, so that a passage is formed between the first cable body and the second cable body.

[0016] Furthermore, there are two sets of clamping blocks, and the two sets of clamping blocks are symmetrically distributed.

[0017] By adopting the above technical solution, during the process of the staff pushing the male and female connectors to close, the two clamping blocks move in opposite directions under the drive of the bidirectional screw through the meshing of the rack and gear, clamping and fixing the first cable body and the second cable body. Thus, while fixing the male and female connectors, the copper cores of the first and second cable bodies are also clamped and fixed, reducing the number of operation steps for the staff and making the connection process faster and more convenient.

[0018] Furthermore, the clamping block is in the shape of an inverted "C", and a copper sheet is connected to the bottom of each clamping block.

[0019] By adopting the above technical solution, the copper sheet is made of pure copper, which has excellent conductivity. Driven by the two clamping blocks, the copper sheet contacts the copper core of the first cable body and the copper core of the second cable body, thereby connecting the first cable body and the second cable body together to form a circuit.

[0020] Furthermore, the first sealing cap is threadedly connected to the male connector, and the second sealing cap is threadedly connected to the female connector.

[0021] By adopting the above technical solution, the workers screw the first sealing cap into the male connector side and the second sealing cap into the female connector side, so that the first sealing cap and the second sealing cap fix the male connector and the female connector onto the first cable body and the second cable body, respectively. At the same time, by cooperating with the clamping claws, the sealing performance of the connection between the male connector and the first cable body and the connection between the female connector and the second cable body is improved, thereby preventing water from seeping into the device from the connection.

[0022] Furthermore, the fixed base has locking blocks connected to both sides inside by springs, and the locking blocks abut against the clamping blocks.

[0023] By adopting the above technical solution, multiple mounting slots are opened on both sides of the fixed seat. The spring and the locking block are normally retracted in the mounting slots. One end of the locking block abuts against the clamping block. When the first cable body and the second cable body are fixed, the two locking blocks move in opposite directions under the drive of the bidirectional screw. When the clamping block loses contact with the locking block, the locking block pops out of the mounting slot under the action of the spring force, thereby fixing and locking the clamping block, improving the locking effect of the clamping block on the copper core of the first cable body and the copper core of the second cable body.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model is equipped with gears, racks, and a bidirectional lead screw. When the operator pushes the male connector towards the female connector, the sealing cylinder moves the rack. Under the action of the rack, the gear drives the bidirectional lead screw to rotate, thereby moving the two clamping blocks and simultaneously clamping and fixing the first and second cable body copper cores. In this way, while fixing the male and female connectors, the first and second cable body copper cores are clamped and fixed, reducing the operator's steps and making the connection process faster and more convenient, thus improving installation efficiency.

[0026] 2. This utility model is equipped with clamping claws, a first sealing cover, and a second sealing cover. When the operator rotates the first sealing cover to connect with the male connector, the first sealing cover squeezes the clamping claws during its movement, causing the clamping claws to press tightly against the outer wall of the first cable body, thereby fixing the male connector to the first cable body. This makes the first sealing cover and the male connector connected as a whole, and at the same time seals one side of the male connector to prevent water from seeping into the connector from the connection point, thus improving the sealing effect of the device (the connection method between the second sealing cover and the female connector is the same as the connection method between the first sealing cover and the male connector).

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1: A cable protection pipe connection joint, such as Figures 1-8 As shown, the cable includes a first cable body 1 and a second cable body 20. The outer surface of the first cable body 1 is fitted with a first sealing cap 2 and a male connector 3. A limiting ring 4 is fitted inside the male connector 3. Limiting holes 7 are formed on both sides of the limiting ring 4. A sealing cylinder 5 is connected to one side of the limiting ring 4, and a rack 6 is connected inside the sealing cylinder 5. The outer surface of the second cable body 20 is fitted with a second sealing cap 16 and a female connector 8. A pressure plate 9 is connected to one end of the female connector 8. A fixing seat 10 is connected to one side of the inside of the female connector 8. A bidirectional lead screw 11 is installed in the middle of the fixing seat 10 via a limiting block 13. A gear 12 is connected to the top of the bidirectional lead screw 11, and a clamping block 14 is threaded onto the outer surface of the bidirectional lead screw 11. The clamping block 14 is slidably connected to the fixed base 10. The second cable body 20 is movably connected to the second sealing cover 16 and the female connector 8, respectively. The first cable body 1 is movably connected to the first sealing cover 2 and the male connector 3, respectively. The operator first passes the second cable body 20 through the second sealing cover 16 and the female connector 8, so that the copper core of the second cable body 20 enters the fixed base 10. By rotating the second sealing cover 16 and cooperating with the clamping claw 15, the female connector 8 is fixed on the second cable body 20, so that the female connector 8 and the second cable body 20 are connected as a whole, which facilitates subsequent installation (the connection method of the first cable body 1 with the first sealing cover 2 and the male connector 3 has the same function).

[0039] See Figure 2 , Figure 3 , Figure 4 and Figure 5In the above embodiment, both the inner side of the male connector 3 and the outer side of the female connector 8 are threaded, and the male connector 3 and the female connector 8 are threadedly connected. When the operator pushes the male connector 3 towards the female connector 8, when the thread on the inner side of the male connector 3 corresponds to the thread on the outer surface of the female connector 8, the male connector 3 is rotated to connect the male connector 3 and the female connector 8 into a whole through the thread, thereby sealing the fixed seat 10.

[0040] See Figure 3 , Figure 4 , Figure 5 and Figure 6 In the above embodiment, clamping claws 15 are connected to both the male connector 3 and the female connector 8. The clamping claws 15 are made of elastic plastic. When the operator rotates the first sealing cover 2, the first sealing cover 2 rotates and moves towards the male connector 3. The first sealing cover 2 presses the clamping claws 15, causing the clamping claws 15 to retract and fit tightly against the outside of the first cable body 1, thereby fixing the first cable body 1. Through the cooperation of the clamping claws 15 and the first sealing cover 2, the first cable body 1 and the male connector 3 are connected as a whole, preventing water from seeping into the interface from the male connector 3 side (the connection method between the second sealing cover 16 and the female connector 8 is the same as the connection method between the first sealing cover 2 and the male connector 3).

[0041] See Figure 3 , Figure 4 and Figure 5 In the above embodiment, the pressure plate 9 is slidably connected to the limiting hole 7, and the limiting ring 4 is rotatably connected to the male connector 3. When the operator rotates the male connector 3, the pressure plate 9 cooperates with the limiting hole 7 to limit the limiting ring 4, preventing the limiting ring 4 from rotating. This would cause the sealing cylinder 5 to drive the rack 6 to rotate, which would collide with the gear 12 and cause interference, thus affecting the practicality of the device.

[0042] See Figure 3 , Figure 4 and Figure 5 In the above embodiment, gear 12 meshes with rack 6. The operator aligns pressure plate 9 with limiting hole 7 and pushes male connector 3 toward female connector 8. During the pushing process, sealing cylinder 5 drives rack 6 to move. Through the meshing of rack 6 and gear 12, rack 6 drives gear 12 to rotate. Under the drive of gear 12, bidirectional lead screw 11 drives two clamping blocks 14 to move in opposite directions, clamping and pressing the copper core of the first cable body 1 and the copper core of the second cable body 20, fixing the first cable body 1 and the second cable body 20 in the fixing seat 10 at the same time, so that a passage is formed between the first cable body 1 and the second cable body 20.

[0043] See Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8In the above embodiment, there are two sets of clamping blocks 14, and the two sets of clamping blocks 14 are symmetrically distributed. During the process of the worker pushing the male connector 3 and the female connector 8 to close, the rack 6 meshes with the gear 12, and under the drive of the bidirectional screw 11, the two clamping blocks 14 move in opposite directions to clamp and fix the first cable body 1 and the second cable body 20. Thus, while fixing the male connector 3 and the female connector 8, the copper core of the first cable body 1 and the copper core of the second cable body 20 are clamped and fixed, reducing the operation steps of the worker and making the docking process faster and more convenient.

[0044] See Figure 4 , Figure 5 , Figure 7 and Figure 8 In the above embodiment, the clamping block 14 is in the shape of an inverted "C", and the bottom of each clamping block 14 is connected to a copper sheet 17. The copper sheet 17 is made of pure copper, which has excellent conductivity. Under the action of the two clamping blocks 14, the copper sheet 17 contacts the copper core of the first cable body 1 and the copper core of the second cable body 20, thereby connecting the first cable body 1 and the second cable body 20 together to form a circuit.

[0045] See Figures 1-6 In the above embodiment, the first sealing cover 2 is threadedly connected to the male connector 3, and the second sealing cover 16 is threadedly connected to the female connector 8. The operator screws the first sealing cover 2 into one side of the male connector 3 and the second sealing cover 16 into one side of the female connector 8, so that the first sealing cover 2 and the second sealing cover 16 fix the male connector 3 and the female connector 8 onto the first cable body 1 and the second cable body 20, respectively. At the same time, by cooperating with the clamping claw 15, the sealing performance of the connection between the male connector 3 and the first cable body 1 and the connection between the female connector 8 and the second cable body 20 is improved, thereby preventing water from seeping into the device from the connection.

[0046] Example 2: To prevent loosening at the connection between the copper core of the first cable body 1 and the copper core of the second cable body 20, Example 2 is an improvement on Example 1. (See attached document.) Figure 8 The fixing base 10 has two sides connected by springs 18 with locking blocks 19 inside, and the locking blocks 19 abut against the clamping block 14. Multiple mounting slots are opened on both sides inside the fixing base 10. The springs 18 and locking blocks 19 are normally retracted in the mounting slots. One end of the locking block 19 abuts against the clamping block 14. When the first cable body 1 and the second cable body 20 are fixed, the two locking blocks 19 move in opposite directions under the drive of the bidirectional screw 11. When the clamping block 14 loses contact with the locking blocks 19, the locking blocks 19 pop out of the mounting slot under the elastic force of the spring 18, thereby fixing and locking the clamping block 14, improving the locking effect of the clamping block 14 on the copper core of the first cable body 1 and the copper core of the second cable body 20.

[0047] The implementation principle of this utility model is as follows: When connecting the first cable body 1 and the second cable body 20, the operator first passes the second sealing cover 16 and the female connector 8 through the second cable body 20, allowing the copper core of the second cable body 20 to enter the fixing seat 10. By screwing the second sealing cover 16 into the female connector 8, the second sealing cover 16 presses the clamping claw 15, causing the clamping claw 15 to retract and tightly adhere to the outside of the second cable body 20, thus fixing the second cable body 20. Through the cooperation of the clamping claw 15 and the second sealing cover 16, the second cable body 20 and the female connector 8 are connected as a whole. Then, the operator passes the first sealing cover 2 and the male connector 3 through the first cable body 1, and inserts the copper core of the first cable body 1 into the fixing seat 10. At this time, the pressure plate 9 is aligned with the limiting hole 7, and the operator moves the male connector 3 towards the female connector 8. During the movement, gear 12 contacts rack 6. Through the meshing of gear 12 and rack 6, gear 12 drives the bidirectional lead screw 11 to rotate, thereby driving clamping blocks 14 to move in opposite directions. Through the interaction force of the two sets of clamping blocks 14, the copper core of the first cable body 1 and the copper core of the second cable body 20 are clamped and fixed. Through the contact of copper sheet 17 with the copper core of the first cable body 1 and the copper core of the second cable body 20, the first cable body 1 and the second cable body 20 are connected into a whole and form a passage. When the internal thread of the male connector 3 corresponds to the external thread of the female connector 8, the male connector 3 is rotated to connect the male connector 3 and the female connector 8 into a whole through the thread. After completion, the first sealing cover 2 is rotated to fix the male connector 3 on the first cable body 1 (the operation method is the same as the operation method of the second sealing cover 16 and the female connector 8), thereby completing the docking.
