Description

Technical Field

[0001] This invention relates to the field of cable connector technology, and more specifically to a quick connector device for medium-voltage cross-linked cables. Background Technology

[0002] Medium-voltage cross-linked cables are used for medium-voltage power transmission. Their conductors are mostly copper or aluminum, and the insulation layer is made of cross-linked polyethylene. The cross-linking reaction improves the performance and can effectively isolate current. Some cables have shielding layers inside and outside, made of semi-conductive materials, to optimize the electric field distribution. It is often filled with materials to enhance mechanical strength and aging resistance. Some have armor layers to prevent mechanical damage, and the outer sheath protects the cable from environmental corrosion. This cable has excellent electrical performance, good heat resistance, high mechanical strength, is not limited by elevation difference when laid, has a long service life and is environmentally friendly. It is widely used in urban power grids, industrial power distribution, commercial buildings, transportation and energy fields.

[0003] Medium-voltage cross-linked cable joints connect two sections of medium-voltage cross-linked cables to ensure stable power transmission. They must maintain good conductivity and mechanical strength of the conductor connection, as well as ensure insulation, sealing, and uniform electric field. The structure includes a conductor connection section, where conductors are joined by crimping or welding; an insulation section to restore insulation performance, often using heat-shrinkable, cold-shrinkable, or prefabricated insulation materials; a shielding section to reconstruct internal and external shielding and optimize the electric field; and a sealing section to prevent moisture and impurities from entering. During manufacturing, strict adherence to procedures is required, including cleaning, stripping, connecting, insulation treatment, and sealing. After completion, insulation resistance and withstand voltage tests must be performed before use. Since most existing joint devices are slow, we have proposed a quick-connect device for medium-voltage cross-linked cables. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a quick coupling device for medium-voltage cross-linked cables, comprising:

[0005] A grooved plate, wherein a groove is inclinedly formed on the top of the grooved plate, a cover plate is fixedly connected to the side of the grooved plate, and a receiving groove is formed on the side of the grooved plate near the cover plate.

[0006] A fixing mechanism is disposed inside the grooved plate and is slidably connected to the inner side of the grooved plate;

[0007] A connector mechanism, which is fixedly connected to the inner side of the groove plate;

[0008] A cleaning mechanism is disposed inside a receiving groove, and the surface of the cleaning mechanism is fixedly connected to the inner side of the receiving groove.

[0009] The connector mechanism includes:

[0010] A positive electrode plate, wherein a buffer assembly is fixedly connected to the side of the positive electrode plate near the cover plate, and the side of the buffer assembly away from the positive electrode plate is fixedly connected to the inner side of the groove plate.

[0011] A negative electrode plate, with a driving component disposed directly above it. The end of the driving component is fixedly connected to the surface of the negative electrode plate, and the driving component is slidably connected to the inner side of the groove plate.

[0012] Both the positive and negative plates are configured as semi-circular rings, and the positive and negative plates form a complete ring.

[0013] After stripping the cables, the two cables are inserted from both sides of the fixing mechanism. The fixing mechanism secures the cables, bringing the cable cores into contact. The joint of the two cables contacts the positive electrode plate, and the buffer structure cushions the positive electrode plate. Subsequently, the drive assembly moves the negative electrode plate close to the positive electrode plate, and the negative electrode plate contacts the cable core. Current flows through the two cable cores, causing them to melt rapidly. The negative electrode plate applies pressure to the cable cores, forming a welded joint. The buffer structure cushions the positive electrode plate when pressure is applied, preventing excessive pressure on the cable cores and thus preventing the melted cable cores from being over-compressed and overflowing from the ring structure formed by the positive and negative electrode plates.

[0014] Furthermore, protrusions are fixedly connected to the sides of the positive and negative plates that are close to each other. Several protrusions are provided and are evenly distributed around the circumference of the annular structure formed by the positive and negative plates. The protrusions can compact the local parts of the cable core more tightly, making the connection between the two cable cores tighter. Several indentations are pressed into the surface of the cable core, which can provide a tighter connection effect when the cable is deformed axially. In addition, the distribution of several protrusions on the surfaces of the positive and negative plates can limit the melting of the cable core and further prevent the melting cable core from overflowing.

[0015] Furthermore, the buffer assembly includes a buffer plate, which is fixedly connected to the positive electrode plate near the cover plate. A sliding rod is symmetrically arranged on the side of the buffer plate away from the positive electrode plate, and the surface of the sliding rod is arc-connected to the inner surface of the buffer plate. A connecting plate is arranged on the side of the sliding rod away from the buffer plate, and the side of the connecting plate away from the sliding rod is fixedly connected to the inner surface of the grooved plate. The ends of both sliding rods located outside the buffer plate are fixedly connected to the side of the connecting plate near the buffer plate. The cable core presses against the positive electrode plate, causing the positive electrode plate to move. The buffer plate slides on the surface of the sliding rod, limiting the position of the buffer plate, thereby limiting the position of the positive electrode plate.

[0016] Furthermore, each of the two slide rods is fixedly connected to a first spring at one end inside the buffer plate. The end of the first spring away from the slide rod is fixedly connected to the inner side of the buffer plate, and the surface of the first spring is slidably connected to the inner side of the buffer plate. When the buffer plate slides on the surface of the slide rod, the first spring deforms, thereby achieving a buffering effect.

[0017] Furthermore, the driving assembly includes a rod, with a frame slidably connected to its outer side. The frame has a dovetail groove structure on its inner side and a dovetail structure on its outer side. The inner side of the frame is slidably connected to the surface of the rod, and the outer side of the frame is slidably connected to the inner side of the grooved plate. The rod is positioned directly above the negative electrode plate, and its end is fixedly connected to the surface of the negative electrode plate. A handle is fixedly connected to the end of the rod away from the negative electrode plate. By holding the handle, the rod is moved horizontally or vertically, allowing the negative electrode plate to approach or move away from the positive electrode plate. The dovetail groove structure on the inner side of the frame provides a limit during vertical movement, and the dovetail structure on the outer side of the frame provides a limit during horizontal movement, ensuring that the negative electrode plate can stably contact the positive electrode plate.

[0018] Furthermore, the fixing mechanism includes a C-shaped ring, which is symmetrically arranged inside the grooved plate. The outer side of the C-shaped ring is slidably connected to the inner side of the grooved plate. A fixing ring is fixedly connected to the inner side of the C-shaped ring, and the fixing ring is made of elastic material. The cable is inserted into the groove, and then the cable enters the inside of the fixing ring through the notch of the fixing ring. The fixing ring deforms and fixes the cable. Then, the C-shaped ring is driven to move, which in turn drives the fixing ring to move, and finally drives the cable to move. The two cables are fixed inside the two fixing rings respectively, and finally the exposed parts of the two cables contact the positive electrode plate.

[0019] Furthermore, a plate body is provided on the side of the cover plate away from the grooved plate. A limiting rod is fixedly connected to the side of the plate body near the cover plate. The end of the limiting rod away from the plate body extends through the cover plate into the interior of the grooved plate. The surface of the limiting rod is slidably connected to the inner side of the cover plate and the inner side of the grooved plate. The end of the limiting rod located in the grooved plate extends into the interior of the C-shaped ring, and the limiting rod is C-shaped bent inside the C-shaped ring. The surface of the limiting rod is fixedly connected to the inner side of the C-shaped ring. The outer side of the limiting rod... The part is equipped with a second spring. The end of the second spring is fixedly connected to the side of the C-ring near the cover plate, and the end of the second spring away from the C-ring is fixedly connected to the inner side of the groove plate. When the C-ring moves, it drives the limiting rod to move, which in turn drives the plate to move. The limiting rod slides inside the groove plate, thereby achieving a limiting effect. When the C-ring moves, it causes the second spring to deform, thereby achieving a buffering effect. The limiting rod extends into the inside of the C-ring, which can maintain the shape of the C-ring while providing a limiting effect, preventing the C-ring from deforming arbitrarily and causing the cable to tilt.

[0020] Furthermore, a spring plate is provided at the interval between the C-shaped ring and the fixed ring. The two sides of the spring plate are fixedly connected to the sides of the C-shaped ring and the fixed ring that are close to each other. The spring plate is hollow and the two sides of the spring plate are bent towards the side that is close to each other. Several spring plates are evenly distributed along the circumference of the C-shaped ring. When the fixed ring deforms, it causes the spring plate to deform. Under the elastic force of the spring plate and the fixed ring restoring their deformation, the cable can be clamped better. Since the spring plate is hollow and the two sides of the spring plate are bent towards the side that is close to each other, when the spring plate deforms, the bending position will deform first, which can limit the deformation position of the spring plate and prevent the spring plate from bending arbitrarily and causing the cable to tilt.

[0021] Furthermore, the cleaning mechanism includes a hole body, which is formed on the top of the inner side of the grooved plate, and several holes are evenly distributed on the top of the inner side of the grooved plate. A tube body is provided at the bottom of the inner side of the grooved plate, and the side of the tube body away from the hole body extends into the receiving groove. The outer side of the tube body is fixedly connected to the inner side of the grooved plate. An air suction component is provided inside the receiving groove. The air suction component drives the hole body and the tube body to generate suction. The hole body adsorbs the fumes generated during welding, and the tube body adsorbs the welding slag generated during welding.

[0022] Furthermore, the air suction assembly includes a first connecting pipe, a pump body is fixedly connected to the side of the first connecting pipe near the pipe body, a second connecting pipe is fixedly connected to the end of the pump body away from the first connecting pipe, a serpentine tube is fixedly connected to the end of the second connecting pipe away from the pump body, and the serpentine tube is positioned directly below the pipe body. The end of the serpentine tube away from the second connecting pipe penetrates a grooved plate, and the outer side of the serpentine tube is fixedly connected to the inner side of the grooved plate. The end of the pipe body located inside the receiving groove is fixedly connected to the outer side of the serpentine tube, and several tubes are evenly distributed along the serpentine path of the serpentine tube. The airflow enters the receiving tank through the orifice, and then sequentially passes through the first connecting pipe, the pump body, the second connecting pipe, and the serpentine pipe. Finally, the airflow enters the outside of the grooved plate. The airflow inside the serpentine pipe reduces the pressure, thereby generating suction inside the pipe to absorb the welding slag. The orifice and pipe design can absorb fumes and welding slag, maintain the cleanliness inside the grooved plate, and collect the welding slag. The airflow inside the serpentine pipe can cool the inside of the grooved plate, ensuring rapid cooling after cable welding is completed. The temperature of the welding slag entering the pipe is also rapidly reduced, preventing welding slag from adhering to the inside of the pipe and the serpentine pipe.

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

[0024] 1. By setting a joint mechanism and a buffer structure, this invention can buffer the positive electrode plate when pressure is applied, avoiding excessive pressure on the cable core. This prevents the melted cable core from being over-compressed and overflowing from the annular structure formed by the positive and negative electrode plates. The protrusions can compact the local parts of the cable core more tightly, making the connection between the two cable cores tighter. Several indentations are pressed into the surface of the cable core, which can provide a tighter connection effect when the cable is deformed axially. Furthermore, several protrusions are distributed on the surfaces of the positive and negative electrode plates, which can limit the melted cable core and further prevent the melted cable core from overflowing.

[0025] 2. By setting up a driving component, the dovetail groove structure on the inner side of the frame can provide a limit when moving vertically, and the dovetail structure on the outer side of the frame can provide a limit when moving horizontally, ensuring that the negative electrode plate can stably contact the positive electrode plate.

[0026] 3. This invention, through the setting of a fixing mechanism, allows the limiting rod to slide inside the groove plate, thereby achieving a limiting effect. The movement of the C-shaped ring causes the second spring to deform, thus achieving a buffering effect. The limiting rod extends into the inside of the C-shaped ring, which can maintain the shape of the C-shaped ring while providing a limiting effect, preventing the C-shaped ring from deforming arbitrarily and causing the cable to tilt. The deformation of the fixing ring causes the elastic plate to deform. Under the elastic force of the elastic plate and the fixing ring restoring their deformation, the cable can be clamped better. Since the elastic plate is hollow and its two sides are bent towards each other, when the elastic plate deforms, the bending position deforms first, which can limit the deformation position of the elastic plate and prevent the elastic plate from bending arbitrarily and causing the cable to tilt.

[0027] 4. This invention, through the setting of cleaning components, uses orifices to adsorb welding fumes and tubes to adsorb welding slag. The airflow inside the serpentine tube reduces pressure, thereby generating suction within the tube to absorb the welding slag. The arrangement of orifices and tubes can absorb fumes and welding slag, maintain the cleanliness of the groove plate, and collect the welding slag in a concentrated manner. The airflow inside the serpentine tube can cool the groove plate, ensuring rapid cooling after cable welding is completed, and the temperature of the welding slag entering the tube is also rapidly reduced, preventing welding slag from adhering to the tube and the inside of the serpentine tube.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed.

[0038] Example 1, please refer to Figures 1-6 This invention relates to a quick-connect device for medium-voltage cross-linked cables, comprising:

[0039] The grooved plate 1 has a groove 2 at the top of it, and a cover plate 6 is fixedly connected to the side of the grooved plate 1. A receiving groove 7 is provided on the side of the grooved plate 1 near the cover plate 6.

[0042] The cleaning mechanism 5 is disposed inside the receiving groove 7, and the surface of the cleaning mechanism 5 is fixedly connected to the inner side of the receiving groove 7.

[0043] The connector mechanism 4 includes:

[0044] A positive electrode plate 41 is fixedly connected to a buffer assembly 42 on the side of the positive electrode plate 41 near the cover plate 6, and the side of the buffer assembly 42 away from the positive electrode plate 41 is fixedly connected to the inner side of the groove plate 1.

[0045] A negative electrode plate 43 is provided, and a driving component 44 is provided directly above the negative electrode plate 43. The end of the driving component 44 is fixedly connected to the surface of the negative electrode plate 43, and the driving component 44 is limited and slidably connected to the inner side of the groove plate 1.

[0046] Both the positive electrode plate 41 and the negative electrode plate 43 are set as semi-circular rings, and the positive electrode plate 41 and the negative electrode plate 43 form a complete ring;

[0047] After stripping the cables, the two cables are inserted from both sides of the fixing mechanism 3. The fixing mechanism 3 fixes the cables, making the cable cores of the two cables contact each other. The joint of the two cables contacts the positive electrode plate 41. The buffer structure buffers the positive electrode plate 41. Then the driving component 44 drives the negative electrode plate 43 to approach the positive electrode plate 41. The negative electrode plate 43 contacts the cable core, and the current passes through the two cable cores. The cable cores melt rapidly, and the negative electrode plate 43 applies pressure to the cable cores to form a welded joint. The buffer structure can buffer the positive electrode plate 41 when pressure is applied, avoiding excessive pressure on the cable cores, thereby preventing the melted cable cores from being over-compressed and overflowing the annular structure formed by the positive electrode plate 41 and the negative electrode plate 43.

[0048] Both the positive electrode plate 41 and the negative electrode plate 43 are fixedly connected to the side of each other. Several protrusions 45 are provided, and the protrusions 45 are evenly distributed around the circumference of the ring structure formed by the positive electrode plate 41 and the negative electrode plate 43. The protrusions 45 can compact the local part of the cable core more tightly, making the connection between the two cable cores tighter. Several indentations are pressed into the surface of the cable core, which can provide a tighter connection effect when the cable is deformed axially. Furthermore, the protrusions 45 are distributed on the surface of the positive electrode plate 41 and the negative electrode plate 43, which can limit the melting of the cable core and further prevent the melting cable core from overflowing.

[0049] The buffer assembly 42 includes a buffer plate 421, which is fixedly connected to the positive electrode plate 41 near the cover plate 6. A sliding rod 422 is symmetrically arranged on the side of the buffer plate 421 away from the positive electrode plate 41, and the surface of the sliding rod 422 is connected to the inner side arc of the buffer plate 421. A connecting plate 423 is arranged on the side of the sliding rod 422 away from the buffer plate 421, and the side of the connecting plate 423 away from the sliding rod 422 is fixedly connected to the inner side of the groove plate 1. The ends of both sliding rods 422 located outside the buffer plate 421 are fixedly connected to the side of the connecting plate 423 near the buffer plate 421. When the cable core presses against the positive electrode plate 41, the positive electrode plate 41 moves the buffer plate 421. The buffer plate 421 slides on the surface of the sliding rod 422, limiting the position of the buffer plate 421, thereby limiting the position of the positive electrode plate 41.

[0050] Two sliding rods 422 are fixedly connected to one end inside the buffer plate 421 with a first spring 424. The end of the first spring 424 away from the sliding rod 422 is fixedly connected to the inner side of the buffer plate 421, and the surface of the first spring 424 is slidably connected to the inner side of the buffer plate 421. The buffer plate 421 slides on the surface of the sliding rod 422, and the first spring 424 is deformed, thereby achieving a buffering effect.

[0051] The drive assembly 44 includes a rod 441, a frame 442 slidably connected to the outer side of the rod 441, a dovetail groove structure on the inner side of the frame 442, a dovetail structure on the outer side of the frame 442, a limiting sliding connection between the inner side of the frame 442 and the surface of the rod 441, and a limiting sliding connection between the outer side of the frame 442 and the inner side of the groove plate 1. The rod 441 is positioned directly above the negative electrode plate 43, and the end of the rod 441 is fixedly connected to the surface of the negative electrode plate 43. A handle 443 is fixedly connected to the end of the rod 441 away from the negative electrode plate 43. By holding the handle 443, the rod 441 is moved horizontally or vertically, allowing the negative electrode plate 43 to approach or move away from the positive electrode plate 41. The dovetail groove structure on the inner side of the frame 442 provides a limit during vertical movement, and the dovetail structure on the outer side of the frame 442 provides a limit during horizontal movement, ensuring that the negative electrode plate 43 can stably contact the positive electrode plate 41.

[0052] The fixing mechanism 3 includes a C-shaped ring 31, which is symmetrically arranged inside the groove plate 1. The outer side of the C-shaped ring 31 is slidably connected to the inner side of the groove plate 1. A fixing ring 32 is fixedly connected to the inner side of the C-shaped ring 31. The fixing ring 32 is made of elastic material. The cable is inserted into the groove 2. Then the cable enters the inside of the fixing ring 32 through the notch. The fixing ring 32 deforms and fixes the cable. Then the C-shaped ring 31 is driven to move, which drives the fixing ring 32 to move, and finally drives the cable to move. The two cables are fixed inside the two fixing rings 32 respectively. Finally, the exposed parts of the two cables contact the positive electrode plate 41.

[0053] A plate 35 is provided on the side of the cover plate 6 away from the groove plate 1. A limiting rod 33 is fixedly connected to the side of the plate 35 near the cover plate 6. The end of the limiting rod 33 away from the plate 35 extends through the cover plate 6 into the groove plate 1. The surface of the limiting rod 33 is slidably connected to the inner side of the cover plate 6 and the inner side of the groove plate 1. The end of the limiting rod 33 located in the groove plate 1 extends into the C-shaped ring 31, and the limiting rod 33 is C-shaped bent inside the C-shaped ring 31. The surface of the limiting rod 33 is fixedly connected to the inner side of the C-shaped ring 31. A second spring is sleeved on the outside of the limiting rod 33. 34. The end of the second spring 34 is fixedly connected to the side of the C-ring 31 near the cover plate 6. The end of the second spring 34 away from the C-ring 31 is fixedly connected to the inner side of the groove plate 1. When the C-ring 31 moves, it drives the limiting rod 33 to move, which in turn drives the plate 35 to move. The limiting rod 33 slides inside the groove plate 1, thereby achieving a limiting effect. When the C-ring 31 moves, it causes the second spring 34 to deform, thereby achieving a buffering effect. The limiting rod 33 extends into the inside of the C-ring 31, which can maintain the shape of the C-ring 31 while providing a limiting effect, thus preventing the C-ring 31 from deforming arbitrarily and causing the cable to tilt.

[0054] A spring plate 36 is provided at the interval between the C-shaped ring 31 and the fixed ring 32. The two sides of the spring plate 36 are fixedly connected to the sides of the C-shaped ring 31 and the fixed ring 32 that are close to each other. The spring plate 36 is hollow and the two sides of the spring plate 36 are bent towards the side that is close to each other. Several spring plates 36 are evenly distributed along the circumference of the C-shaped ring 31. When the fixed ring 32 deforms, it causes the spring plate 36 to deform. Under the elastic force of the spring plate 36 and the fixed ring 32 restoring their deformation, the cable can be clamped better. Since the spring plate 36 is hollow and the two sides of the spring plate 36 are bent towards the side that is close to each other, when the spring plate 36 deforms, the bending position will deform first, which can limit the deformation position of the spring plate 36 and prevent the spring plate 36 from bending arbitrarily and causing the cable to tilt.

[0055] Example 2, please refer to Figures 1-8 The cleaning mechanism 5 includes a hole 51, which is opened on the top of the inner side of the groove plate 1. Several holes 51 are evenly distributed on the top of the inner side of the groove plate 1. A tube 52 is provided at the bottom of the inner side of the groove plate 1. The side of the tube 52 away from the hole 51 extends into the receiving groove 7. The outer side of the tube 52 is fixedly connected to the inner side of the groove plate 1. An air suction component 53 is provided inside the receiving groove 7. The air suction component 53 drives the hole 51 and the tube 52 to generate suction. The hole 51 adsorbs the fumes generated by welding, and the tube 52 adsorbs the welding slag generated by welding.

[0056] The air suction assembly 53 includes a first connecting pipe 531. A pump body 532 is fixedly connected to the side of the first connecting pipe 531 near the pipe body 52. ​​A second connecting pipe 533 is fixedly connected to the end of the pump body 532 away from the first connecting pipe 531. A serpentine pipe 534 is fixedly connected to the end of the second connecting pipe 533 away from the pump body 532, and the serpentine pipe 534 is located directly below the pipe body 52. ​​The end of the serpentine pipe 534 away from the second connecting pipe 533 passes through the groove plate 1, and the outer side of the serpentine pipe 534 is fixedly connected to the inner side of the groove plate 1. The end of the pipe body 52 located inside the receiving groove 7 is fixedly connected to the outer side of the serpentine pipe 534, and several pipe bodies 52 are evenly distributed along the serpentine path of the serpentine pipe 534. The pump body 531 is activated. 32. The airflow enters the receiving groove 7 through the orifice 51, and then passes through the first connecting pipe 531, pump body 532, second connecting pipe 533, and serpentine pipe 534 in sequence. Finally, the airflow enters the outside of the groove plate 1. The airflow inside the serpentine pipe 534 reduces the pressure, thereby generating suction in the pipe body 52 to absorb the welding slag. The arrangement of the orifice 51 and the pipe body 52 can absorb the fumes and welding slag, maintain the cleanliness of the inside of the groove plate 1, and collect the welding slag. The airflow inside the serpentine pipe 534 can cool the inside of the groove plate 1, ensuring rapid cooling after the cable welding is completed. The temperature of the welding slag entering the pipe body 52 also decreases rapidly, preventing the welding slag from adhering to the inside of the pipe body 52 and the serpentine pipe 534.

[0057] In use, the cable is inserted into the groove 2, and then enters the fixed ring 32 through the notch. The fixed ring 32 deforms, causing the spring plate 36 to deform as well. Under the elastic force of the spring plate 36 and the fixed ring 32 recovering their deformation, the cable is clamped and fixed. Then, the C-shaped ring 31 is driven to move, which in turn moves the fixed ring 32, ultimately moving the cable. The cable core presses against the positive electrode plate 41, which in turn moves the buffer plate 421. The buffer plate 421 slides on the surface of the slide rod 422, causing the first spring 424 to deform. The two cables are then fixed inside the two fixed rings 32 respectively. The exposed part of the cable contacts the positive electrode plate 41. Holding the handle 443, the rod 441 is moved horizontally or vertically, allowing the negative electrode plate 43 to approach or move away from the positive electrode plate 41. The negative electrode plate 43 contacts the cable core, and current flows through the two cable cores. The cable cores melt rapidly, and the negative electrode plate 43 applies pressure to the cable cores to form a welded joint. The pump body 532 is started, and the fumes and airflow enter the receiving groove 7 through the orifice 51. Then, they pass through the first connecting pipe 531, the pump body 532, the second connecting pipe 533, and the serpentine pipe 534 in sequence. Finally, the airflow enters the outside of the groove plate 1. The airflow inside the serpentine pipe 534 reduces the pressure, thereby generating suction inside the pipe body 52 to absorb the welding slag.
