Description

Technical Field

[0001] This invention belongs to the field of cable connector technology, specifically a high-voltage cable connector. Background Technology

[0002] When laying and connecting high-voltage cables, a special connector is needed to connect the disconnected ends of the high-voltage cables.

[0003] For example, Chinese patent CN115764452A discloses a high-voltage cable connector, including a male head and a female head; a ring body is fixedly connected to the middle position of the male head and the female head, and an annular groove is opened in the middle position of the outer ring of the ring body. A connecting mechanism is provided between the two ring bodies; the connecting mechanism includes multiple first rods, second rods and threaded cylinders; the ends of the second rods and first rods are threadedly connected to the threaded cylinders; an external toothed ring is fixedly connected to the outer ring of each threaded cylinder; an internal toothed ring is fixedly connected to the inner ring of the drive ring, and the internal toothed ring meshes with the external toothed ring. Through the structural design of the threaded cylinder and the drive ring, compared with the traditional method of tightening with bolts, the connector provided by this invention can drive multiple threaded cylinders to rotate and tighten the ring body at one time, so that the male head and the female head are brought closer and squeezed together, saving time, reducing the time of continuous high-intensity labor, and reducing installation time and operational safety risks when placed at height.

[0004] In existing technologies, a large number of mechanical parts are used to connect disconnected high-voltage cables. In practical applications, the accumulation of a large number of mechanical parts can easily lead to the following defects:

[0005] Firstly, the sealing of high-voltage cable connections cannot be guaranteed. Due to the presence of numerous mechanical parts, compared to traditional conduits, the winding of insulation layers and other methods cannot guarantee absolute sealing.

[0006] Secondly, traditional connecting pipes are inexpensive and easy to manufacture, requiring only casting to complete the process. In contrast, existing connecting devices can only be used once, are more expensive, and are relatively difficult to manufacture.

[0007] Third, when connecting disconnected high-voltage cables, traditional connecting pipes often overlook the alignment issue between the wire end and the connecting pipe body. If the friction between the connecting pipe body and the wire end is too heavy, it will lead to a reduction in service life, and the connection part will be easily punctured during subsequent use of the cable.

[0008] Therefore, the present invention provides a high-voltage cable connector. Summary of the Invention

[0013] The auxiliary module includes an end cap, a tensioning handle, a connecting arm, and a clamping part. The end cap is installed at the end of the connecting tube. Three tensioning handles are arranged in a circumferential array and are hinged to the side wall of the end cap. One end of the connecting arm is hinged to the side wall of the tensioning handle, and the other end is hinged to the side wall of the clamping part.

The three fixing plates are engaged end-to-end to form a whole. The stop block is hinged to the other end of the connecting arm. The pressing block is slidably engaged with the stop block. The pressing block is radially slidably connected to the fixing plate. When the tensioning handle is turned, the stop block squeezes the pressing block and moves it centripetally onto the fixing plate, applying pressure to the disconnected high-voltage cable sheath. As the connecting arm moves, the high-voltage cable is carried into the connecting tube.

[0015] Preferably, the surfaces of the abutment and the pressure block that slide together are both set as inclined surfaces, and a slider is fixedly connected to the inclined surface of the abutment, and the abutment is slidably connected to the inclined surface of the pressure block via the slider; a first connecting ear is fixedly connected to the top of the abutment, and one end of the connecting arm is hinged to the first connecting ear.

[0016] Preferably, a connecting rod is fixedly connected to the side of the fixing plate facing the end, and one end of the connecting rod is fixedly connected to the fixing plate, while the other end is slidably connected to the end; a first spring is sleeved on the connecting rod, and the two ends of the first spring are respectively fixedly connected to the end and the side wall of the fixing plate.

[0017] Preferably, a base plate is fixedly connected to the bottom of one side of the fixing plate corresponding to the pressure block, and a vertical rod is fixedly connected to the base plate. A second spring is sleeved on the vertical rod. A connecting plate is fixedly connected to the top of the pressure block. The vertical rod passes through the connecting plate, and the two ends of the second spring are respectively fixed to the base plate and the connecting plate.

[0018] Preferably, a plug is fixed to the side wall of the end, and the end is inserted into the connecting pipe body via the plug; three ends are provided, and the three ends are spliced ​​end to end, keeping the sides horizontal.

[0019] Preferably, a lead screw is fixedly connected to the middle of the tensioning handle, and a connecting part is slidably connected to the lead screw, the connecting part being locked to the lead screw by a nut; a second connecting lug is fixedly connected to the connecting part, and the other end of the connecting arm is hinged to the second connecting lug.

[0020] Preferably, the connecting tube has a cable fixing cavity inside, and the auxiliary module carries the disconnected high-voltage cable and inserts it into the cable fixing cavity in the connecting tube. Both ends of the connecting tube are provided with docking grooves corresponding to the insertion rods; the ends are inserted into the docking grooves via the insertion rods.

[0021] Preferably, the surface of the connecting tube is provided with three protrusions and a relief groove; the relief groove and the protrusions are staggered, and when the tensioning handle is rotated, they fit into the relief groove; the mating groove is opened in the protrusion; the connecting tube is also provided with multiple threaded holes corresponding to the protrusions, and the threaded holes are threaded with pressure caps; the pressure caps are used to press the high-voltage cable inserted into the connecting tube.

[0022] Preferably, the insertion rod has a semi-circular hole, and the insertion rods of two adjacent ends are inserted into a joint groove, and the semi-circular holes on the insertion rods are merged into a perfect circular hole, and the pressure cap passes through the perfect circular hole to fix the end.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The high-voltage cable connector of the present invention, by setting a connecting tube and an auxiliary module that matches and cooperates with the connecting tube, can realize the functions of clamping and aligning the high-voltage cable and carrying the high-voltage cable into the connecting tube. After the high-voltage cable is pressed with the connecting tube, the auxiliary module can be removed, leaving only the connecting tube, which facilitates subsequent steps such as winding the insulation layer, reduces excess gaps, and improves sealing performance. Furthermore, the clamping of the high-voltage cable and alignment of the connecting tube by the auxiliary module can reduce the friction between the high-voltage cable and the connecting tube when it is inserted, thereby reducing resistance and the risk of the connection part being broken down.

[0025] 2. The high-voltage cable connector of the present invention applies a component force toward the axis of the connecting tube to the pressure block by displacing the abutment block toward the connecting tube body, thereby displacing the pressure block toward the axis of the connecting tube body and applying greater pressure to the outer sheath of the high-voltage cable. Based on the pressure, the friction is increased, and the pressure block and the outer sheath of the high-voltage cable remain relatively stationary. At this time, the tensioning handle continues to rotate. Based on the sliding fit between the abutment block and the pressure block, the clamping part moves toward the connecting tube body along with the connecting arm, thereby completing the insertion of the high-voltage cable into the connecting tube body.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 8 As shown in the figure, a high-voltage cable connector according to an embodiment of the present invention includes a connecting tube 1 and an auxiliary module 2; the connecting tube 1 is used to connect two disconnected high-voltage cables.

[0038] The auxiliary module 2 is detachably installed at both ends of the connecting pipe body 1 and is used to carry the disconnected high-voltage cable, align it with the connecting pipe body 1, and insert it into the connecting pipe body 1. The auxiliary module 2 includes an end 23, a tensioning handle 21, a connecting arm 22, and a clamping part. The end 23 is installed at the end of the connecting pipe body 1. Three tensioning handles 21 are arranged in a circumferential array and are hinged to the side wall of the end 23. One end of the connecting arm 22 is hinged to the side wall of the tensioning handle 21, and the other end is hinged to the side wall of the clamping part. The clamping part is used to clamp the disconnected high-voltage cable. When the clamping part clamps the disconnected cable, the tensioning handle 21 is turned, and the connecting arm 22 carries the high-voltage cable, aligns it with the connecting pipe body 1, and inserts it into the connecting pipe body 1.

[0039] In existing technologies, a large number of mechanical parts are used to connect disconnected high-voltage cables. In practical applications, the accumulation of a large number of mechanical parts can easily lead to the following defects:

[0040] Firstly, the sealing of the 27-position high-voltage cable connection cannot be guaranteed. Due to the presence of many mechanical parts, compared to traditional pipe bodies, the winding of insulation layers and other processes cannot guarantee absolute sealing.

[0041] Secondly, traditional connecting pipes are inexpensive and easy to manufacture, requiring only casting to complete the process. In contrast, existing connecting devices can only be used once, are more expensive, and are relatively difficult to manufacture.

[0042] Third, when connecting disconnected high-voltage cables, traditional connecting pipes often overlook the alignment of the wire end with the connecting pipe body 1. If the friction between the connecting pipe body 1 and the wire end is too heavy, it will lead to a reduction in service life, and the connection part 27 is easily punctured during subsequent use of the cable.

[0043] To address the aforementioned issues, this embodiment designs a similar-shaped connecting tube 1 based on the traditional connecting tube shape. This connecting tube 1 is relatively simple to manufacture. In use, the auxiliary module 2 is connected to the connecting tube 1. After inserting the disconnected high-voltage cable into the connecting tube 1, the auxiliary module 2 can be detached, leaving only the connecting tube 1. This facilitates the winding of the insulation layer and subsequent operations. Specifically, in the application phase of this embodiment: first, the auxiliary module 2 is detachably installed at both ends of the connecting tube 1; then, the disconnected high-voltage cable is placed at both ends of the connecting tube 1; subsequently... The operator connects the disconnected high-voltage cable using auxiliary module 2. Specifically, the clamping part holds the cable in place on its outer sheath, ensuring the cable end is coaxial with the connecting tube 1. This pre-alignment prevents excessive friction between the cable end and the connecting tube 1 when the cable end is inserted into the tube by auxiliary module 2, avoiding severe wear and tear on the tube end. This prevents changes in the resistance of the connecting part 27 and the risk of breakdown due to resistance variations. The operator then moves the tensioning handle 21. Figure 1 As shown, the tension handle 21 is rotated toward the side wall of the connecting tube 1. The clamping part, driven by the connecting arm 22, carries the high-voltage cable and inserts it into the connecting tube 1. As the tension handle 21 gradually approaches the side wall of the connecting tube 1, the clamping part completes the purpose of carrying and inserting the cable into the connecting tube 1. Then, before the auxiliary module 2 is disassembled, the connecting tube 1 and the high-voltage cable are pressed together. Finally, the auxiliary module 2 is disassembled, leaving only the connecting tube 1, thus completing the connection of the disconnected high-voltage cable. Based on the above, in this embodiment, by setting the connecting tube 1 to... The auxiliary module 2, which works in conjunction with the connecting tube 1, can clamp and align the high-voltage cable and carry it into the connecting tube 1. After the high-voltage cable is pressed against the connecting tube 1, the auxiliary module 2 can be removed, leaving only the connecting tube 1. This facilitates subsequent steps such as winding the insulation layer, reduces excess gaps, and improves sealing. Furthermore, the clamping and alignment of the high-voltage cable with the connecting tube 1 achieved by the auxiliary module 2 can reduce friction between the high-voltage cable and the connecting tube 1 when it is inserted, thereby reducing resistance and the risk of the connection part 27 being broken down.

[0044] like Figures 1 to 3 As shown, the clamping part includes a fixing plate 24, a stop block 25, and a pressing block 26. Three fixing plates 24 are arranged in a circumferential array. The three fixing plates 24 are engaged end to end to form a whole. The stop block 25 is hinged to the other end of the connecting arm 22. The pressing block 26 is slidably engaged with the stop block 25. The pressing block 26 is radially slidably connected to the fixing plate 24. When the tensioning handle 21 is turned, the stop block 25 squeezes the pressing block 26 and moves it centripetally onto the fixing plate 24, applying pressure to the disconnected high-voltage cable sheath. As the connecting arm 22 moves, it carries the high-voltage cable into the connecting tube 1.

[0045] When the operator moves the tension handle 21 from a vertical position to gradually approach the side wall of the connecting pipe 1, the tension handle 21, based on the connecting arm 22, drives the clamping part to gradually approach the connecting pipe 1. Therefore, the clamping part is pre-connected to the outer sheath of the disconnected high-voltage cable, and the purpose of inserting the high-voltage cable into the connecting pipe 1 can be completed after moving the tension handle 21. However, considering cost and operational continuity, in this embodiment, based on the fixed plate 24, the abutment block 25, and the pressure block 26, the action of the tension handle 21 is coordinated to achieve self-fixation of the high-voltage cable, reduce operation steps, and improve the continuity of disconnecting the high-voltage cable connection. Specifically, before moving the tension handle 21, the operator inserts the disconnected high-voltage cable into the two clamping parts respectively. It is worth noting that in this embodiment, the middle part of the fixed plate 24 is provided with A through hole is provided, and the size of the through hole is larger than the outer diameter of the high-voltage cable sheath. Therefore, the high-voltage cable can be easily inserted. After the operator moves the tension handle 21, the tension handle 21 gradually moves from a vertical position to the surface of the connecting tube 1. During this process, the pressure block 26 and the abutment block 25 slide relative to each other. Since the abutment block 25 is directly hinged to the connecting arm 22, the abutment block 25 will slide on the pressure block 26 and squeeze the pressure block 26 radially, thereby reducing the size of the inscribed circle formed by the edges of multiple pressure blocks 26, thereby achieving the clamping action of the high-voltage cable sheath. As the connecting arm 22 drives the clamping part to move, the clamping of the high-voltage cable and the insertion of the high-voltage cable into the connecting tube 1 can be achieved in sequence. The pressure block 26 and the abutment block 25 are slidably connected and will never separate.

[0046] like Figures 1 to 3 , Figure 7 As shown, the surfaces of the abutment block 25 and the pressure block 26 that slide together are both set as inclined surfaces, and a slider is fixedly connected to the inclined surface of the abutment block 25. The abutment block 25 is slidably connected to the inclined surface of the pressure block 26 via the slider. A first connecting ear 251 is fixedly connected to the top of the abutment block 25, and one end of the connecting arm 22 is hinged to the first connecting ear 251.

[0047] As mentioned above, assuming the pressure block 26 is driven by a spring and pre-pressed onto the outer sheath of the high-voltage cable, creating a certain frictional force between the pressure block 26 and the outer sheath of the high-voltage cable, the tensioning handle 21 is moved, and the connecting arm 22 causes the abutment block 25 to shift. Since the mating surfaces of the abutment block 25 and the pressure block 26 are both inclined surfaces, and as... Figure 7As shown, when the abutment block 25 moves toward the connecting tube body 1, it applies a component force toward the axis of the connecting tube body 1 to the pressure block 26, causing the pressure block 26 to move toward the axis of the connecting tube body 1, which can also be understood as centripetal displacement. This applies greater pressure to the outer sheath of the high-voltage cable. Based on the pressure, the friction is greater, and the pressure block 26 and the outer sheath of the high-voltage cable remain relatively stationary. At this time, the tensioning handle 21 continues to rotate. Based on the sliding fit between the abutment block 25 and the pressure block 26, the clamping part moves toward the connecting tube body 1 along with the connecting arm 22, thereby completing the insertion of the high-voltage cable into the connecting tube body 1.

[0048] like Figures 1 to 4 As shown, a connecting rod 241 is fixedly connected to the side of the fixed plate 24 facing the end 23, and one end of the connecting rod 241 is fixedly connected to the fixed plate 24, while the other end is slidably connected to the end 23; a first spring 242 is sleeved on the connecting rod 241, and the two ends of the first spring 242 are respectively fixed to the end 23 and the side wall of the fixed plate 24.

[0049] In the above embodiment, the clamping part and the end 23 are connected only by the connecting arm 22. During the process of the clamping part carrying the high-voltage cable to move based on the connecting arm 22, the high-voltage cable may deviate due to its own weight. Therefore, in this embodiment, when the tensioning handle 21 is rotated, the connecting arm 22 drives the abutment block 25 and the pressure block 26 to generate relative displacement. After the clamping part completes the pre-fixation of the high-voltage cable, the clamping part will move towards the connecting tube 1 with the displacement of the connecting arm 22 and carry the high-voltage cable into the connecting tube 1. During the process, the sliding cooperation between the connecting rod 241 and the end 23 ensures the fixation. Plate 24 never shifts, thus overcoming the shifting problem caused by the weight of the high-voltage cable itself. Furthermore, a first spring 242 is provided on the connecting rod 241. When not in motion, the first spring 242 releases its elastic force, driving the fixed plate 24 away from the end 23. That is, a force parallel to the axis of the connecting tube 1 is applied to the fixed plate 24, causing the fixed plate 24 and the pressure block 26 on the fixed plate 24 to move away from the end 23. When the connecting arm 22 drives the pressure block 26 to shift, the pressure block 26 and the abutment block 25 are more likely to slide relative to each other. Therefore, it can be understood that in this embodiment, the pressure block 26 can pre-press the outer sheath of the high-voltage cable without the aid of a spring.

[0050] like Figures 1 to 5 As shown, the fixing plate 24 is fixedly connected to the bottom of one side of the pressure block 26 with a base plate 243, and a vertical rod is fixedly connected to the base plate 243. A second spring 262 is sleeved on the vertical rod. A connecting plate 261 is fixedly connected to the top of the pressure block 26. The vertical rod passes through the connecting plate 261, and the two ends of the second spring 262 are respectively fixed to the base plate 243 and the connecting plate 261.

[0051] As described above, due to the cooperation between the first spring 242 and the connecting rod 241, the clamping part, under the rotation of the tension handle 21, carries the high-voltage cable into the connecting tube 1, without the need for a spring to drive the pressure block 26 to pre-press on the outer sheath of the high-voltage cable. Considering that when the high-voltage cable is inserted into the clamping part, if the pressure block 26 is only slidably connected to the fixed plate 24 without being subjected to other forces, it may cause the multiple pressure blocks 26 to be asymmetrically distributed, resulting in friction between the outer sheath and individual pressure blocks 26 when the high-voltage cable is inserted, causing scratches, in this embodiment, since the pressure block 26 does not need to be pre-pressed on the high-voltage cable by a spring, and due to the cooperation of the first spring 242 and the connecting rod 241, the reverse... The force is directed to achieve relative sliding between the pressure block 26 and the abutment block 25. Therefore, the pressure block 26 can maintain its relative position under the action of the second spring 262. That is, based on the second spring 262, when the pressure block 26 does not slide relative to the abutment block 25, the multiple pressure blocks 26 are distributed symmetrically around the circumference. When the high-voltage cable is inserted into the clamping part, there will be no friction with the pressure block 26. When the abutment block 25 and the pressure block 26 are in sliding engagement, the abutment block 25 can overcome the elastic force of the second spring 262 and drive the pressure block 26 to apply a large pressure to the outer sheath of the high-voltage cable. Thus, relative stillness with the high-voltage cable is achieved based on friction. Subsequently, with the rotation of the tensioning handle 21, the high-voltage cable end is driven to pass into the connecting tube 1.

[0052] like Figures 1 to 6 As shown, a plug rod 231 is fixedly connected to the side wall of the end 23, and the end 23 is inserted into the connecting pipe body 1 via the plug rod 231; three ends 23 are provided, and the three ends 23 are spliced ​​end to end, keeping the sides horizontal.

[0053] To facilitate the subsequent removal of the auxiliary module 2, in this embodiment, when the detachable end 23 is installed, the insertion rod 231 is used to connect with the connecting tube 1 to achieve the installation. Similarly, to facilitate removal, the end 23 is also set to three, and the ends are spliced ​​together. When removing, the fixing plate 24 can be removed in advance, and then the end 23 can be pulled out.

[0054] like Figures 1 to 3 As shown, a lead screw 211 is fixedly connected to the middle of the tensioning handle 21, and a connecting part 27 is slidably connected to the lead screw 211. The connecting part 27 is locked to the lead screw 211 by a nut. A second connecting ear 271 is fixedly connected to the connecting part 27, and the other end of the connecting arm 22 is hinged to the second connecting ear 271.

[0055] In this embodiment, the lead screw 211 in the middle of the tensioning handle 21 can be adjusted at multiple angles in conjunction with the connecting part 27. It is understood that after the connecting part 27 changes position, the stroke of the clamping part that can be driven by turning the tensioning handle 21 will change.

[0056] like Figures 1 to 8 As shown, the connecting tube 1 has a cable fixing cavity 16 inside. The auxiliary module 2 carries the disconnected high-voltage cable and inserts it into the cable fixing cavity 16 in the connecting tube 1. Both ends of the connecting tube 1 are provided with docking grooves 15 corresponding to the insertion rod 231. The end 23 is inserted into the docking groove 15 via the insertion rod 231.

[0057] like Figures 1 to 8 As shown, the surface of the connecting tube 1 is provided with three protrusions 14 and relief grooves 12; the relief grooves 12 and the protrusions 14 are staggered, and when the tensioning handle 21 is rotated, they fit into the relief grooves 12; the mating grooves 15 are opened in the protrusions 14; the connecting tube 1 is also provided with a plurality of threaded holes 11 corresponding to the protrusions 14, and the threaded holes 11 are threaded with pressure caps 13; the pressure caps 13 are used to press the high-voltage cable inserted into the connecting tube 1.

[0058] In the prior art, a pressure cap 13 is pre-threaded into the threaded hole 11 on the connecting tube body 1. When the auxiliary module 2, carrying the disconnected high-voltage cable, is inserted into the connecting tube body 1, the pressure cap 13 can be screwed in using a tool such as a hex wrench. After the pressure cap 13 is screwed into the connecting tube body 1, the end of the high-voltage cable inserted into the connecting tube body 1 can be compacted, thereby completing the connection of the disconnected high-voltage cable based on the connecting tube body 1. Subsequently, the auxiliary module 2 can be removed. It is worth noting that a relief groove 12 and a protrusion 14 are provided on the surface of the connecting tube body 1. By moving the tensioning handle 21, the tensioning handle 21 can be made to fit into the relief groove 12. The protrusion 14 is mainly used to prevent the pressure cap 13 screwed into the connecting tube body 1 from protruding from the surface of the connecting tube body 1, which facilitates the subsequent winding of the insulation layer. In addition, the mating groove 15 provided at the end can be used for the detachable connection of the end 23.

[0059] like Figures 1 to 8 As shown, the insertion rod 231 has a semi-circular hole 232. The insertion rods 231 on two adjacent ends 23 are inserted into a joint groove 15, and the semi-circular holes 232 on the insertion rods 231 are combined into a perfect circular hole. The pressure cap 13 passes through the perfect circular hole to fix the end 23.

[0060] Based on the above, the insertion of the end 23 into the docking slot 15 via the insertion rod 231 may pose a risk of detachment during operation. To eliminate this risk, based on the pre-connection of the pressure cap 13 and the threaded hole 11 mentioned in the above embodiment, a semi-circular hole 232 can be opened on the insertion rod 231, and the two insertion rods 231 can be inserted into one docking slot 15, so that the two semi-circular holes 232 are merged into one circular hole. Then, the pressure cap 13 is screwed in, which limits the insertion rod 231 and prevents the auxiliary module 2 from detaching. After the high-voltage cable has been inserted into the connecting tube 1, the pressure cap 13 is screwed in further, so that the pressure cap 13 is detached from the insertion rod 231. At this time, the insertion rod 231 can be pulled out directly. Based on the above, by using the cooperation of the pressure cap 13, the threaded hole 11, the semi-circular hole 232 and the insertion slot, the auxiliary module 2 and the connecting tube 1 can be quickly and easily installed and disassembled.

[0061] Working principle: Based on the traditional shape of connecting pipes, a similarly shaped connecting pipe body 1 is designed. This connecting pipe body 1 is relatively simple to manufacture. In use, the auxiliary module 2 is connected to the connecting pipe body 1. After inserting the disconnected high-voltage cable into the connecting pipe body 1, the auxiliary module 2 can be detached, leaving only the connecting pipe body 1. This facilitates the winding of the insulation layer and subsequent operations. Specifically, in this embodiment, during the application stage: first, the auxiliary module 2 is detachably installed at both ends of the connecting pipe body 1. Then, the disconnected high-voltage cable is placed at both ends of the connecting pipe body 1. Subsequently, the operator... Based on the connection of the disconnected high-voltage cable using auxiliary module 2, specifically, the clamping part is used to hold the high-voltage cable sheath, keeping the cable end coaxial with the connecting tube 1. This is to pre-align the high-voltage cable end with the connecting tube 1, preventing excessive friction on the end of the connecting tube 1 when the cable end is inserted into the connecting tube 1 by auxiliary module 2. This prevents severe wear on the end of the connecting tube 1, which could lead to changes in the resistance of the connecting part 27 and make it prone to breakdown due to resistance changes. Subsequently, the operator moves the tensioning handle 21, as... Figure 1As shown, the tension handle 21 is rotated toward the side wall of the connecting tube 1. The clamping part, driven by the connecting arm 22, carries the high-voltage cable and inserts it into the connecting tube 1. As the tension handle 21 gradually approaches the side wall of the connecting tube 1, the clamping part completes the purpose of carrying the cable and inserting it into the connecting tube 1. Then, before the auxiliary module 2 is disassembled, the connecting tube 1 and the high-voltage cable are pressed together. Finally, the auxiliary module 2 is disassembled, leaving only the connecting tube 1, thus completing the connection of the disconnected high-voltage cable. Based on the above, in this embodiment, by setting the connecting tube 1 and the connecting... The auxiliary module 2, matched with the connector body 1, enables the clamping and alignment of the high-voltage cable and facilitates its insertion into the connector body 1. After the high-voltage cable is clamped to the connector body 1, the auxiliary module 2 can be removed, leaving only the connector body 1. This facilitates subsequent steps such as winding the insulation layer, reduces excess gaps, and improves sealing. Furthermore, the clamping and alignment of the high-voltage cable with the connector body 1 achieved by the auxiliary module 2 reduces friction between the high-voltage cable and the connector body 1 during insertion, thereby reducing resistance and the risk of breakdown at the connection point 27. Based on the fixing plate 2... 4. The abutment block 25 and the pressure block 26, in conjunction with the action of the tensioning handle 21, achieve self-fixation of the high-voltage cable, reducing operation steps and improving the continuity of disconnecting the high-voltage cable connection. Specifically, before moving the tensioning handle 21, the operator inserts the disconnected high-voltage cable into the two clamping parts respectively. It is worth noting that in this embodiment, the fixing plate 24 has a through hole in the middle, and the size of the through hole is larger than the outer diameter of the high-voltage cable sheath. Therefore, the high-voltage cable can be easily inserted, and after the operator moves the tensioning handle 21, the tensioning handle 21 gradually moves from a vertical position closer to the clamping part. During the process of connecting the surface of the tube body 1, the pressure block 26 and the abutment block 25 slide relative to each other. Since the abutment block 25 is directly hinged to the connecting arm 22, the abutment block 25 will slide on the pressure block 26 and squeeze the pressure block 26 radially, thereby reducing the size of the inscribed circle formed by the edges of multiple pressure blocks 26, thereby achieving the clamping action of the high-voltage cable sheath. As the connecting arm 22 drives the clamping part to move, the clamping of the high-voltage cable and the insertion of the high-voltage cable into the connecting tube body 1 can be achieved in sequence. The pressure block 26 and the abutment block 25 are slidably connected and will never separate.

[0062] Assuming the pressure block 26 is driven by a spring and pre-pressed onto the outer sheath of the high-voltage cable, creating friction between the pressure block 26 and the cable sheath, the tensioning handle 21 is moved, causing the connecting arm 22 to displace the abutment block 25. Since the mating surfaces of the abutment block 25 and the pressure block 26 are both inclined planes, and as... Figure 7As shown, when the abutment block 25 moves toward the connecting tube body 1, it applies a component force toward the axis of the connecting tube body 1 to the pressure block 26, causing the pressure block 26 to move toward the axis of the connecting tube body 1, which can also be understood as centripetal displacement. This applies greater pressure to the outer sheath of the high-voltage cable. Based on the pressure, the friction is greater, and the pressure block 26 and the outer sheath of the high-voltage cable remain relatively stationary. At this time, the tensioning handle 21 continues to rotate. Based on the sliding fit between the abutment block 25 and the pressure block 26, the clamping part moves toward the connecting tube body 1 along with the connecting arm 22, thereby completing the insertion of the high-voltage cable into the connecting tube body 1.

[0063] When the tension handle 21 is rotated, the connecting arm 22 causes relative displacement between the abutment block 25 and the pressure block 26. After the clamping part completes the pre-fixation of the high-voltage cable, the clamping part will move towards the connecting tube 1 with the displacement of the connecting arm 22, and insert the high-voltage cable into the connecting tube 1. During the process, the sliding cooperation between the connecting rod 241 and the end 23 ensures that the fixing plate 24 does not shift, thereby overcoming the shift problem caused by the weight of the high-voltage cable itself; and furthermore, in the connecting rod 24... A first spring 242 is provided on the 1. When not in operation, the first spring 242 releases its elastic force, driving the fixing plate 24 away from the end 23. That is, a force parallel to the axis of the connecting pipe 1 is applied to the fixing plate 24, causing the fixing plate 24 and the pressure block 26 on the fixing plate 24 to move away from the end 23. When the connecting arm 22 drives the pressure block 26 to move, the pressure block 26 and the abutment block 25 are more likely to slide relative to each other. Therefore, it can be understood that in this embodiment, the pressure block 26 can pre-press the outer sheath of the high-voltage cable without the aid of a spring.

[0064] Due to the cooperation between the first spring 242 and the connecting rod 241, the clamping part, under the rotation of the tension handle 21, carries the high-voltage cable into the connecting tube 1 without the need for a spring to drive the pressure block 26 to pre-press on the outer sheath of the high-voltage cable. Considering that if the pressure block 26 is only slidably connected to the fixed plate 24 without being subjected to other forces when the high-voltage cable is inserted into the clamping part, it may lead to asymmetrical distribution of multiple pressure blocks 26, causing friction between the outer sheath and individual pressure blocks 26 during insertion, resulting in scratches, in this embodiment, since the pressure block 26 does not need to be pre-pressed on the high-voltage cable by a spring, and due to the cooperation of the first spring 242 and the connecting rod 241, the reverse... The force is used to achieve relative sliding between the pressure block 26 and the abutment block 25. Therefore, the pressure block 26 can maintain its relative position under the action of the second spring 262. That is, based on the second spring 262, when the pressure block 26 does not slide relative to the abutment block 25, the multiple pressure blocks 26 are distributed symmetrically around the circumference. When the high-voltage cable is inserted into the clamping part, there will be no friction with the pressure block 26. When the abutment block 25 and the pressure block 26 are in sliding engagement, the abutment block 25 can overcome the elastic force of the second spring 262 and drive the pressure block 26 to apply a large pressure to the outer sheath of the high-voltage cable. Thus, relative stillness with the high-voltage cable is achieved based on friction. Subsequently, with the rotation of the tensioning handle 21, the high-voltage cable end is driven to pass into the connecting tube 1.
