Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more specifically to a series constant power hot and cold wire connector. Background Technology

[0002] Hot and cold wires are common conductors in the electrical field. Generally, some heat-generating devices will have hot and cold wires. The cold wire is the part close to the power line and is used to conduct electricity. The cold wire is connected to the hot wire to conduct current into the hot wire, and the hot wire generates heat when energized. Therefore, the cold wire and the hot wire need to be connected with a connector.

[0003] The Chinese patent authorization announcement number is CN215835573U, entitled "A Carbon Fiber Hot and Cold Wire Connector". It includes a body, a wire is installed on one end of the outer wall of the body, and a clamping mechanism is provided at both ends of the outer wall of the body. The clamping mechanism includes a transmission mechanism and an arc plate. The arc plates are arranged in pairs. After the hot and cold wires are connected, the transmission mechanism drives the arc plates so that the two arc plates fix and clamp the wire, thereby achieving wire fastening.

[0004] The shortcomings of the existing technical solutions are as follows: Although the above solutions can fix the wire body by clamping it with an arc plate, the hot wire body will experience large temperature changes during power switching or due to changes in ambient temperature. This can easily cause thermal expansion and contraction of the fasteners such as the arc plate. Over time, gaps may form between the fasteners and the wire body. The existing fasteners are fixed in place once, and once gaps occur between them and the wire body, they cannot be automatically repaired. If maintenance is not timely, the wire body can easily loosen, thus affecting its use. Furthermore, the existing hot and cold wire bodies are not convenient to connect. Summary of the Invention

[0005] The purpose of this invention is to provide a series constant power cold and hot wire connector to solve the technical problems in the prior art where the cold and hot wire connector cannot be automatically repaired when the wire becomes loose, and the wiring operation is not convenient enough.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A series constant power hot and cold wire connector includes a connecting sleeve;

[0008] The bottom two sides of the connecting sleeve are respectively inclinedly connected to the threaded tubes; the connecting sleeve is provided with a rotating winding mechanism;

[0009] Both conduits are equipped with top pressure plates, and slide rods are connected to the top pressure plates. The slide rods penetrate the side walls of the conduits, and a sliding sleeve is slidably fitted onto the end of the slide rod away from the top pressure plate. A pushing mechanism that cooperates with the sliding sleeve is provided at the bottom of the connecting sleeve. A storage spring is connected between the sliding sleeve and the slide rod. Multiple limiting slots are equidistantly opened on one side of the slide rod. A connecting slider is provided on the side of the sliding sleeve near the end of the slide rod. A limiting block that cooperates with the limiting slots is movably provided at one end of the connecting slider. A position adjustment mechanism is provided at the other end of the connecting slider. The connecting end of the limiting block fits against the end of the connecting slider. The side of the limiting block near the top pressure plate is movably connected to the connecting slider through a spring-loaded hinge.

[0010] As a further embodiment of the present invention: the position adjustment mechanism includes an adjustment bolt and a limiting slide cavity, the limiting slide cavity is formed on the side wall of the sliding sleeve, the adjustment bolt is threadedly connected to the limiting slide cavity, the connecting slider is slidably connected to the limiting slide cavity, and the end of the connecting slider away from the limiting block is rotatably connected to the adjustment bolt.

[0011] As a further embodiment of the present invention: the pushing mechanism includes a connecting screw and a conical top sleeve. The connecting screw is disposed at the bottom of the connecting sleeve, and the conical top sleeve is slidably sleeved on the connecting screw. The outer inclined wall of the conical top sleeve cooperates with the sliding sleeve. A pushing nut is threadedly connected to the connecting screw.

[0012] As a further aspect of the present invention: the end of the sliding sleeve away from the slide rod is a spherical end.

[0013] As a further aspect of the present invention: the rotary winding mechanism includes a fastening screw sleeve; the fastening screw sleeve is threaded to the outside of the connecting sleeve, a pressure sleeve is slidably inserted inside the connecting sleeve, both sides of the pressure sleeve are connected with protruding shanks, both sides of the fastening screw sleeve are provided with strip-shaped sliding openings, and the protruding shanks pass through the strip-shaped sliding openings; the bottom of the pressure sleeve is provided with a clamping mechanism that cooperates with the pressure sleeve.

[0014] As a further embodiment of the present invention: the clamping mechanism includes clamping plates and a crossbar. Two clamping plates are provided and symmetrically distributed in the connecting sleeve. The crossbar passes through the clamping plates. An annular groove is provided on the inner wall of the connecting sleeve. Both ends of the crossbar are slidably connected to the annular groove. Both clamping plates are movably connected to a linkage rod by a hinge. The end of the linkage rod is movably connected to the bottom of the pressure sleeve by a hinge.

[0015] As a further aspect of the present invention, anti-slip grooves are distributed on the outer wall of the clamp.

[0016] As a further aspect of the present invention: both the connecting sleeve and the conduit are insulators.

[0017] The beneficial effects of this invention are:

[0018] 1. When the cold wire and hot wire are inserted into the corresponding conduit for docking, the conical top sleeve can be moved along the connecting screw. The conical top sleeve can act on the sliding sleeves on both sides at the same time, so that the sliding sleeve drives the top pressure plate to fix and press the wire. During this process, the sliding sleeve and the sliding rod contract, causing the storage spring to compress and generate a rebound force. At the same time, the limiting block on the sliding sleeve is locked in the limiting groove on the sliding rod. The combination of the limiting block and the limiting groove allows the sliding rod to slide out relative to the sliding sleeve and not slide into the sliding sleeve. Thus, when the top pressure plate has a gap with the pressed wire due to the temperature change caused by the hot wire being switched on and off or the ambient temperature change, the sliding rod can slide out of the sliding sleeve by the rebound force of the storage spring, causing the top pressure plate to automatically press the wire again. Since the sliding rod cannot slide back due to the interaction of the limiting block and the limiting groove, the top pressure plate can be kept in the position of pressing the wire and the wire can be prevented from loosening.

[0019] 2. In this invention, after the metal ends of the cold and hot wires are inserted into the connecting sleeve through the threading tube, the inserted metal ends cross due to the staggered distribution of the threading tubes on both sides. At this time, the protruding shank can be pressed down, causing the shank to drive the pressure sleeve inside the connecting sleeve to press down on the clamping plate. The clamping plate then clamps the crossed metal ends. Then, the shank is rotated around the connecting sleeve, causing the shank to drive the fastening screw to rotate. The fastening screw rotates and descends, limiting the downward movement of the pressure sleeve. At the same time, it also facilitates the pressure sleeve to drive the clamping plate to rotate, winding the crossed metal ends together to achieve wiring. The operation is convenient and effective.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1-8 As shown, a series constant power hot and cold wire connector includes a connecting sleeve 1. Two threading tubes 2 are obliquely connected to the bottom sides of the connecting sleeve 1, with their positions staggered. The two threading tubes 2 are used to insert a hot wire 21 and a cold wire 22, respectively. After the hot wire 21 and cold wire 22 are connected, the cold wire 22 is energized, and the hot wire 21 is energized to generate heat. Furthermore, when the hot wire 21 and cold wire 22 are inserted from their respective threading tube positions, the hot wire 21... The metal ends of the cold wire 22 and the hot wire 21 are exposed, and the metal ends are inserted into the connecting sleeve 1 through the conduit 2. Since the two conduits 2 are staggered, the metal ends of the cold wire 22 and the hot wire 21 inserted into the connecting sleeve 1 cross each other. Both the connecting sleeve 1 and the conduit 2 are insulators to avoid the risk of electric shock. The connecting sleeve 1 is provided with a rotating winding mechanism for winding the metal ends of the two wires inserted into the connecting sleeve 1.

[0032] The rotary winding mechanism includes a fastening sleeve 11; the fastening sleeve 11 is threaded to the outside of the connecting sleeve 1, and a pressure sleeve 10 is slidably inserted inside the connecting sleeve 1. Both sides of the pressure sleeve 10 are connected to protruding shanks 12, and both sides of the fastening sleeve 11 are vertically provided with strip-shaped openings 13. The protruding shanks 12 pass through the strip-shaped openings 13 and can slide longitudinally along the strip-shaped openings 13. Simultaneously, when the pressure sleeve 10 is rotated via the protruding shanks 12, the protruding shanks 12, being confined within the strip-shaped openings 13, can also drive the fastening sleeve 11 to rotate, causing the fastening sleeve 11 to move up and down along the connecting sleeve 1. A clamping mechanism is provided at the bottom of the pressure sleeve 10, which cooperates with the pressure sleeve 10. The clamping mechanism includes... The device includes clamping plates 9 and a crossbeam 24. Two clamping plates 9 are provided, symmetrically distributed within the connecting sleeve 1. Anti-slip grooves are distributed on the outer wall of the clamping plates 9 to enhance their anti-slip properties. The crossbeam 24 penetrates the clamping plates 9, allowing the two clamping plates 9 to slide along it. An annular groove 23 is provided on the inner wall of the connecting sleeve 1, and both ends of the crossbeam 24 are slidably connected to the annular groove 23, facilitating the rotation of the clamping plates 9 within the connecting sleeve 1. Each clamping plate 9 is movably connected to a linkage rod 14 via a hinge. The end of the linkage rod 14 is movably connected to the bottom of the pressure sleeve 10 via a hinge. When the cold wire body 22... After the metal ends of the wire body 21 and the hot wire body 21 are respectively inserted into the connecting sleeve 1 through the corresponding wire guide tubes 2, the two intersecting metal ends are located between the clamping plates 9. At this time, the outer protruding shank 12 can be pressed down, causing the protruding shank 12 to slide down along the strip-shaped sliding opening 13 on the fastening screw sleeve 11. In this way, the protruding shank 12 drives the pressure sleeve 10 to slide down and insert into the connecting sleeve 1. During this process, the pressure sleeve 10 squeezes the linkage rods 14 on both sides of the bottom. In this way, the linkage rods 14 push the corresponding clamping plates 9 to slide and clamp along the cross frame 24, clamping the intersecting wire metal ends. Then, the protruding shank 12 can be directly operated to rotate around the outside of the connecting sleeve 1. Since the protruding shank 12 passes through the strip-shaped sliding opening 13 on the fastening screw sleeve 11, Thus, the convex shank 12 can drive the fastening sleeve 11 to rotate, and the fastening sleeve 11 moves down along the threaded connecting sleeve 1. During this process, since the convex shank 12 is connected with the strip-shaped sliding mouth 13, the convex shank 12 does not obstruct the fastening sleeve 11 when it descends, and finally the fastening sleeve 11 descends and comes into contact with the pressure sleeve 10, preventing it from rising, thereby keeping the clamping plate 9 clamping the metal end of the wire. When the convex shank 12 rotates around the outside of the connecting sleeve 1, the pressure sleeve 10 rotates inside the connecting sleeve 1. Thus, the pressure sleeve 10 drives the clamping plate 9 to rotate, thereby making the clamped metal end of the wire wrapped together, achieving connection, and can also be clamped and fixed by the clamping plate 9.

[0033] Both conduits 2 are equipped with top pressure plates 8, and slide rods 7 are vertically connected to the top pressure plates 8. The slide rods 7 penetrate the side walls of the conduits 2. A sliding sleeve 6 is slidably fitted onto the end of the slide rod 7 away from the top pressure plate 8. A storage spring 15 connects the sliding sleeve 6 and the slide rod 7. The sliding sleeve 6 and the slide rod 7 are combined to form a telescopic rod. Multiple limiting slots 16 are equidistantly provided on one side of the slide rod 7. A connecting slider 19 is provided on the side of the sliding sleeve 6 near the end of the slide rod 7. A limiting block 20 that cooperates with the limiting slots 16 is movably provided on one end of the connecting slider 19. The connecting end of the limiting block 20 is attached to the end of the connecting slider 19. The side of the limiting block 20 near the top pressure plate 8 is connected to the top pressure plate 8 by a spring-loaded hinge. The connecting slider 19 is movably connected. Since the connecting end of the limiting block 20 is attached to the end of the connecting slider 19, and the movable connection position is on the side edge close to the top pressure plate 8, the limiting block 20 can only rotate from the original position toward the direction close to the top pressure plate 8, and cannot rotate from the original position away from the top pressure plate 8. Furthermore, when the limiting block 20 is engaged in the limiting slot 16 at the corresponding position, the sliding sleeve 6 cannot slide along the sliding rod 7 toward the top pressure plate 8, that is, the combination of the sliding sleeve 6 and the sliding rod 7 cannot slide and retract. When the sliding rod 7 slides out of the sliding sleeve 6, it can squeeze the limiting block 20 to rotate, that is, the combination of the sliding rod 7 and the sliding sleeve 6 can slide and stretch at this time.

[0034] The other end of the connecting slider 19 is provided with a position adjustment mechanism, which includes an adjusting bolt 17 and a limiting slide cavity 18. The limiting slide cavity 18 is opened on the side wall of the sliding sleeve 6. The adjusting bolt 17 is threadedly connected to the limiting slide cavity 18. The connecting slider 19 is slidably connected to the limiting slide cavity 18, and the connecting slider 19 can only slide within the limiting slide cavity 18 and cannot rotate. The end of the connecting slider 19 away from the limiting block 20 is rotatably connected to the adjusting bolt 17. That is, when the adjusting bolt 17 rotates and moves, it can drive the connecting slider 19 to slide within the limiting slide cavity 18. Thus, the adjusting bolt 17 can be rotated as needed to drive the connecting slider 19 to slide, thereby making the limiting block 20 located inside the sliding sleeve 6, which can interact with the limiting slot 16, or it can be stored away and cannot interact with the limiting slot 16.

[0035] The bottom of the connecting sleeve 1 is provided with a pushing mechanism that cooperates with the sliding sleeve 6. The pushing mechanism includes a connecting screw 3 and a conical top sleeve 5. The connecting screw 3 is located at the bottom of the connecting sleeve 1 and is fixed in position relative to the connecting sleeve 1. The conical top sleeve 5 is slidably sleeved on the connecting screw 3, and the outer inclined wall of the conical top sleeve 5 cooperates with the sliding sleeve 6. The end of the sliding sleeve 6 away from the sliding rod 7 is a spherical end, which facilitates contact with the inclined wall of the conical top sleeve 5 and relative sliding. A pushing nut 4 is threadedly connected to the connecting screw 3.

[0036] After the cold wire 22 and the hot wire 21 are inserted into their respective conduits 2, the adjusting bolt 17 is rotated first, causing the connecting slider 19 to slide outwards from the sliding sleeve 6. This allows the limiting block 20 to be housed within the limiting cavity 18, preventing it from interacting with the limiting groove 16. Then, the push nut 4 is rotated upwards along the connecting screw 3, pushing the conical top sleeve 5 upwards. The conical top sleeve 5 then rises along the connecting screw 3. During this process, the inclined walls on both sides of the conical top sleeve 5 press against the corresponding sliding sleeve 6. The sliding sleeve 6 first drives the pressure plate 8 through the sliding rod 7. Pressing down the corresponding wire, the sliding sleeve 6 slides along the sliding rod 7, causing the storage spring 15 to compress and generate a rebound force. The rebound force of the storage spring 15 facilitates the insertion of the sliding rod 7 into the wire guide tube 2, so that the top pressure plate 8 can press the wire tightly. Then, rotating the adjusting bolt 17 causes the adjusting bolt 17 to drive the connecting slider 19 to slide, thereby causing the limiting block 20 to slide into the sliding sleeve 6. In this way, the limiting block 20 is engaged in the limiting slot 16 at the corresponding position on the sliding rod 7. Since the connecting end of the limiting block 20 is attached to the end of the connecting slider 19, and the movable connection position is close to the end of the connecting slider 19, the limiting block 20 is engaged in the limiting slot 16 at the corresponding position on the sliding rod 7. On one side edge of the top pressure plate 8, the limiting block 20 can only rotate from its original position toward the top pressure plate 8, and cannot rotate from its original position toward the direction away from the top pressure plate 8. This coordinated engagement of the limiting block 20 and the limiting groove 16 prevents the combination of the sliding sleeve 6 and the sliding rod 7 from retracting, thus ensuring that the top pressure plate 8 remains in the corresponding position pressing against the wire and cannot move away from it. When a gap develops between the top pressure plate 8 and the pressed wire due to temperature changes during the switching of the hot wire 21 or thermal expansion and contraction caused by changes in ambient temperature, the limiting block 20 and the connecting slider 19... The movable connection position is located on one side edge near the top pressure plate 8, so the combination of slide rod 7 and sliding sleeve 6 can slide and stretch. In this way, the top pressure plate 8 can press against the line body by the elastic force of the storage spring 15, automatically pressing the line body again. During this process, slide rod 7 slides outward relative to sliding sleeve 6, and the limiting block 20 is deflected due to the pressure of the side wall of slide rod 7, making it easy to disengage from the corresponding limiting slot 16. When slide rod 7 stops, the limiting block 20 is locked in the limiting slot 16 at the stopping position, so that slide rod 7 cannot slide back into sliding sleeve 6, keeping the top pressure plate 8 in the top pressure position.

[0037] The working principle of the present invention is as follows: First, the hot wire 21 and the cold wire 22 are respectively inserted into the corresponding wire tube 2, and the metal ends of the hot wire 21 and the cold wire 22 are exposed. In this way, the metal ends are inserted into the connecting sleeve 1 along the wire tube 2. Since the two wire tubes 2 are staggered, the metal ends of the cold wire 22 and the hot wire 21 inserted into the connecting sleeve 1 cross each other and are located between the clamping plates 9.

[0038] Then, rotate the adjusting bolt 17, causing the adjusting bolt 17 to drive the connecting slider 19 to slide outwards from the sliding sleeve 6, so that the limiting block 20 is housed in the limiting slide cavity 18 and cannot interact with the limiting slot 16. Then, rotate the pushing nut 4 upwards along the connecting screw 3, and the pushing nut 4 pushes the conical top sleeve 5 upwards. The conical top sleeve 5 then rises along the connecting screw 3. During this process, the inclined walls on both sides of the conical top sleeve 5 press against the corresponding sliding sleeve 6. The sliding sleeve 6 first drives the top pressure plate 8 to press down the corresponding wire through the sliding rod 7. Then, the sliding sleeve 6 slides along the sliding rod 7, causing the energy storage spring 15 to compress and generate a rebound force. The rebound force of the energy storage spring 15 facilitates the insertion of the sliding rod 7 into the wire guide tube 2, so that the top pressure plate 8 can press the wire. The body is pressed tightly, and then the adjusting bolt 17 is rotated, causing the adjusting bolt 17 to drive the connecting slider 19 to slide, thereby causing the limiting block 20 to slide into the sliding sleeve 6. In this way, the limiting block 20 is engaged in the limiting groove 16 at the corresponding position on the slide rod 7. Since the connecting end of the limiting block 20 is attached to the end of the connecting slider 19, and the movable connection position is on the side edge close to the top pressure plate 8, the limiting block 20 can only rotate from the original position towards the top pressure plate 8, and cannot rotate from the original position away from the top pressure plate 8. The matching limiting block 20 and limiting groove 16 make the combination of the sliding sleeve 6 and the slide rod 7 unable to retract, that is, the top pressure plate 8 keeps pressing the line body at the corresponding position and cannot move away from the line body;

[0039] Then press down the protruding shank 12 on the outside of the connecting sleeve 1, so that the protruding shank 12 slides down along the strip-shaped sliding opening 13 on the fastening threaded sleeve 11. In this way, the protruding shank 12 drives the pressure sleeve 10 to slide down and insert into the connecting sleeve 1. During this process, the pressure sleeve 10 squeezes the linkage rods 14 on both sides of the bottom. In this way, the linkage rods 14 push the corresponding clamping plates 9 to slide and clamp along the cross frame 24, clamping the metal ends of the crossed wires. Then, directly operate the protruding shank 12 to rotate around the outside of the connecting sleeve 1. Since the protruding shank 12 passes through the strip-shaped sliding opening 13 on the fastening threaded sleeve 11, the protruding shank 12 can drive the fastening threaded sleeve 11 to rotate. The fastening threaded sleeve 11 then slides down along the strip-shaped sliding opening 13 on the fastening threaded sleeve 11. As the threaded connecting sleeve 1 moves downward, and during this process, due to the engagement of the shank 12 and the strip-shaped sliding mouth 13, the shank 12 does not obstruct the fastening sleeve 11 when it descends, and finally the fastening sleeve 11 descends and comes into contact with the pressure sleeve 10, preventing it from rising, thereby keeping the clamping plate 9 clamping the metal end of the wire. When the shank 12 rotates around the outside of the connecting sleeve 1, the pressure sleeve 10 rotates inside the connecting sleeve 1. In this way, the pressure sleeve 10 drives the clamping plate 9 to rotate, thereby making the clamped metal end of the wire wrapped together, achieving connection. At the same time, it can also be held and fixed by the clamping plate 9 to complete the connection of hot and cold wires.

[0040] When a gap forms between the pressure plate 8 and the pressed wire due to temperature changes caused by the switching on and off of the hot wire 21 or thermal expansion and contraction caused by changes in ambient temperature, the movable connection position of the limiting block 20 and the connecting slider 19 is located on the side edge close to the pressure plate 8. Therefore, the combination of the slide rod 7 and the sliding sleeve 6 can slide and stretch. In this way, the pressure plate 8 can press against the wire by the elastic force of the storage spring 15, automatically pressing the wire back into place. During this process, the slide rod 7 slides outward relative to the sliding sleeve 6, and the limiting block 20 deflects due to the pressure of the side wall of the slide rod 7, making it easier to disengage from the corresponding limiting slot 16. When the slide rod 7 stops, the limiting block 20 is locked in the limiting slot 16 at the stopping position, preventing the slide rod 7 from sliding back into the sliding sleeve 6, keeping the pressure plate 8 in the pressing position, and completing the automatic tightening.

[0041] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
