Abstract

The present invention relates to the technical field of electronic couplers, and specifically to a coupler connector with stable connection, comprising a coupler 1, wherein a coupler 2 is provided on the right side of the coupler 1; and a connecting mechanism for connecting the coupler 1 and the coupler 2, wherein the connecting mechanism comprises an electric contact disc 1 fixedly installed inside the left end of the coupler 2. In the present invention, when the coupler 1 approaches the coupler 2, it will also drive the elastic pressure strip to move synchronously. When the electric contact disc 1 has not yet contacted the electric contact disc 2, the elastic pressure strip will squeeze the pressure plate, and the pressure plate will drive the connecting rod 1 to slide inside the coupler 2, compressing the spring 2 and the air bag. The gas in the air bag is ejected from the nozzle hole, so that the dust on the side where the electric contact disc 1 and the electric contact disc 2 are close to each other can be cleaned in advance. The dust that falls after cleaning will fall from the opening at the lower end of the limit ring, thereby ensuring the stability of the electric contact disc 1 and the electric contact disc 2 during conductive contact, and avoiding the situation where the dust causes poor contact.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the staff holds the coupler 1, aligns the guide rod with the perforation and inserts it. As the coupler 1 gradually approaches the coupler 2, the coupler 1 drives the spring 1, the ball seat, the ball and the electric contact disc 2 to synchronously approach the coupler 2 until the electric contact disc 2 and the electric contact disc 1 contact each other. The electric contact disc 2 drives the ball and the ball seat to adaptively compress the spring 1 to complete the coupling. At the same time, the adaptive compression spring 1 will also approach and insert the fixed hook plate into the fixed hook groove. When the inclined surface of the fixed hook plate contacts the frame of the fixed hook groove, it will be subjected to an extrusion force, driving the fixed hook plates on both sides to slide on the coupler 2 and approach each other, compressing the spring 3 until the fixed hook plate is fully inserted into the fixed hook groove. The spring 3 pushes the fixed hook plates on both sides to reset, completing the connection and locking fixation of the coupler 1 and the coupler 2, thereby ensuring the connection stability between the coupler 1 and the coupler 2.

[0021] 2. In the present invention, the limiting ring provided can ensure that the sides of the electric contact disc 2 and the electric contact disc 1 that are close to each other are always in stable contact, and there will be no sliding or deviation, thereby ensuring the stability of the electrical connection. When disassembling, it is only necessary to press the buckle groove on the fixed hook plate at the same time to drive the fixed hook plates on both sides to approach each other synchronously, compress the spring 3, and the fixed hook plate can be detached from the fixed hook groove, making disassembly and assembly convenient.

[0022] 3. In the present invention, the guide rods and perforations are provided to improve the accuracy of connecting the coupler 1 and the coupler 2, avoid manual alignment and waste of time, and improve the efficiency of connecting the coupler 1 and the coupler 2.

[0023] 4. In the present invention, when coupler 1 approaches coupler 2, it will also drive the elastic pressure strip to move synchronously. When electric contact disc 1 has not yet contacted electric contact disc 2, the elastic pressure strip will squeeze the pressure plate, and the pressure plate will drive connecting rod 1 to slide toward the inside of coupler 2, compressing spring 2 and the airbag. The gas in the airbag will be ejected from the nozzle hole, so as to facilitate the cleaning of dust on the side where electric contact disc 1 and electric contact disc 2 are close to each other in advance. The dust that falls after cleaning will fall from the opening at the lower end of the limit ring, thereby ensuring the stability of conductive contact between electric contact disc 1 and electric contact disc 2 and avoiding poor contact caused by dust.

[0024] 5. In the present invention, when the connected coupler 1 and coupler 2 are subjected to a large external pulling force, causing the coupler 1 and coupler 2 to deviate in different directions, the provided spring 1 will adaptively deform forward, backward, left and right, and cooperate with the ball to adaptively roll in the ball seat, so that the electric contact disc 2 and the electric contact disc 1 will always be stably fitted together, ensuring the stability of the electrical connection between the coupler 1 and coupler 2.

[0025] 6. In the present invention, when the guide rod is inserted into the through hole, the guide rod on the upper side will contact and push the inclined surface of the fixed inclined plate to rise, and the fixed inclined plate drives the connecting rod 2 to slide and rise on the support plate, compressing the spring 4. When the fixed groove passes the lower side of the fixed inclined plate, the spring 4 drives the fixed inclined plate and the connecting rod 2 to reset, and the lower end of the fixed inclined plate abuts and fits against the upper end of the fixed groove. When the coupler 1 and the coupler 2 are connected and the electric contact plate 2 and the electric contact plate 1 are about to contact, the hook strip is pulled upward to drive the fixed rod plate to slide upward on the movable plate, compressing the spring 5. At this time, the lower end of the fixed rod plate will be separated from the movable plate, and the electric contact plate 1 and the electric contact plate 2 will be fully in contact. After that, the fixed hole plate on the electric contact disc 2 will move between the fixed rod plate and the movable plate, loosening the hook strip, and the spring 5 will drive the fixed rod plate and the hook strip to reset. The fixed rod plate is inserted through the fixed hole plate and fixed. The fixed rod plate, the fixed hole plate and the movable plate are all made of conductive material, contact each other, and form an electrical connection. When the coupler 1 and the coupler 2 are subjected to excessive external force, causing the fixed hook plate and the fixed hook groove to deform and separate, the guide rod slides out of the through hole, and the fixed inclined plate and the fixed groove cooperate to limit the connection between the coupler 1 and the coupler 2 again to prevent the coupler 1 and the coupler 2 from separating.

[0026] 7. In the present invention, the electric contact disc 1 and the electric contact disc 2 are separated, and the fixed hole plate has been integrated with the fixed rod plate, which will pull the fixed rod plate, the movable plate, and the wire to synchronously detach in the direction of coupler 1. At the same time, the wire will adaptively loosen a certain length from the roller, driving the roller and the rotating shaft to adaptively rotate in the empty slot, compressing the torsion spring. At this time, the electric contact disc 2, the fixed hole plate, the fixed rod plate, the movable plate, the wire, the roller, the rotating shaft and the electric contact disc 1 form an electrical connection, thereby ensuring that when coupler 1 and coupler 2 are subjected to a large external force impact, they can still maintain a stable electrical connection, greatly ensuring the connection stability between the couplers.

[0044] During operation, the staff holds the coupler 1 and aligns the guide rod 17 with the through hole 18 and inserts it. As the coupler 1 gradually approaches the coupler 2 2, the coupler 1 drives the spring 1 7, the ball seat 6, the ball 5 and the electric contact disc 2 4 to move synchronously toward the coupler 2 2 until the electric contact disc 2 4 and the electric contact disc 1 3 contact each other. The electric contact disc 2 4 drives the ball 5 and the ball seat 6 to adaptively compress the spring 1 7 to complete the coupling. At the same time, the fixed hook plate 14 will also approach and be inserted into the fixed hook groove 16. When the inclined surface of the fixed hook plate 14 contacts the frame of the fixed hook groove 16, it will be subjected to extrusion force, driving the fixed hook plates 14 on both sides to be on the coupler 2 When the coupling 1 and coupling 2 are closed, the coupling 1 and coupling 2 are locked and fixed, thereby ensuring the connection stability between the coupling 1 and coupling 2.

When the coupler 1 approaches the coupler 2, it will also drive the elastic pressure strip 13 to move synchronously. The elastic pressure strip 13 squeezes the pressure plate 10 before the electric contact disc 1 and the electric contact disc 2 come into contact with the electric contact disc 4.

A fixed inclined plate 19 is provided inside the through-hole 18 on the upper side, and a fixed groove 1901 is provided at the upper end of the guide rod 17 corresponding to the fixed inclined plate 19. A connecting rod 20 is fixedly installed on the upper end of the connecting rod 20, and a support plate 21 is slidably installed on the upper end of the connecting rod 20. The support plate 21 is fixedly installed on the upper end of the coupler 2, and a spring 4 22 is sleeved on the outer side of the connecting rod 20. The upper and lower ends of the spring 4 22 are fixedly connected to the support plate 21 and the fixed inclined plate 19 respectively. A fixed hole plate 23 is fixedly installed on the right end of the electric contact disc 24, and a fixed hole plate 23 is provided on the left end of the electric contact disc 3. There is an empty slot 24, and a fixed rod plate 25 is provided inside the empty slot 24 corresponding to the fixed hole plate 23. A movable plate 26 is slidably installed on the middle part of the fixed rod plate 25. The upper and lower ends of the movable plate 26 are slidably connected to the electric contact disc 3. The lower end of the fixed rod plate 25 is abutted and fitted on the movable plate 26. A spring 5 27 is fixedly installed on the upper end of the fixed rod plate 25. The upper end of the spring 5 27 is fixedly installed on the movable plate 26. A wire 28 is fixedly installed on the right end of the movable plate 26. A roller 29 is fixedly wound around the other end of the wire 28. A rotating shaft 30 is fixedly installed on the front and rear ends of the roller 29. The wire 28, the movable plate 26 and the fixed rod plate 25 are all electrically connected. One end of the rotating shaft 30 is rotatably connected to the inner wall of the empty slot 24. A torsion spring 31 is sleeved on the outer side of the rotating shaft 30. A hook strip 32 is provided on the lower side of the fixed rod plate 25. The hook strip 32 is slidably installed on the coupler 2;

[0046] During operation, when the guide rod 17 is inserted into the through hole 18, the upper guide rod 17 will contact and push the inclined surface of the fixed inclined plate 19 to rise, and the fixed inclined plate 19 will drive the connecting rod 20 to slide and rise on the support plate 21, compressing the spring 4 22. When the fixed groove 1901 passes the lower side of the fixed inclined plate 19, the spring 4 22 drives the fixed inclined plate 19 and the connecting rod 2 20 to reset, and the lower end of the fixed inclined plate 19 abuts against the upper end of the fixed groove 1901. When the coupler 1 and the coupler 2 are connected, and the electric contact plate 2 4 and the electric contact plate 1 3 are about to contact, the hook strip 32 is pulled upward. The movable fixed rod plate 25 slides upward on the movable plate 26, compressing the spring five 27. At this time, the lower end of the fixed rod plate 25 will separate from the movable plate 26. After the electric contact disc 1 3 and the electric contact disc 2 4 are in contact and fitted, the fixed hole plate 23 on the electric contact disc 2 4 will move between the fixed rod plate 25 and the movable plate 26, loosening the hook strip 32. The spring five 27 drives the fixed rod plate 25 and the hook strip 32 to reset. The fixed rod plate 25 is inserted through the fixed hole plate 23 and fixed. The fixed rod plate 25, the fixed hole plate 23 and the movable plate 26 are all made of conductive materials, contact each other, and form an electrical When the coupler 1 and the coupler 2 are subjected to excessive external force, causing the fixed hook plate 14 and the fixed hook groove 16 to deform and separate, the guide rod 17 slides out of the through hole 18, and the fixed inclined plate 19 and the fixed groove 1901 are provided to limit the connection between the coupler 1 and the coupler 2 again to prevent the coupler 1 and the coupler 2 from separating. At the same time, the electric contact plate 13 and the electric contact plate 24 are separated, and the fixed hole plate 23 has been integrated with the fixed rod plate 25, which will pull the fixed rod plate 25, the movable plate 26, and the wire 28 synchronously. When the coupler 1 is disengaged from the coupler 2, at the same time, the wire 28 will adaptively loosen a certain length from the roller 29, driving the roller 29 and the rotating shaft 30 to adaptively rotate in the empty slot 24, compressing the torsion spring 31. At this time, the electric contact disc 2 4, the fixed hole plate 23, the fixed rod plate 25, the movable plate 26, the wire 28, the roller 29, the rotating shaft 30 and the electric contact disc 3 form an electrical connection, thereby ensuring that the coupler 1 and the coupler 2 are still able to maintain a stable electrical connection when subjected to a large external force, thereby greatly ensuring the connection stability between the couplers.

[0047] Working principle:

[0048] When the present invention is used, the staff holds the coupler 1 and aligns the guide rod 17 with the perforation 18 and inserts it. As the coupler 1 gradually approaches the coupler 2, the coupler 1 drives the spring 17, the ball seat 6, the ball 5 and the electric contact disc 24 to move synchronously toward the coupler 2, until the electric contact disc 24 and the electric contact disc 13 contact each other. The electric contact disc 24 drives the ball 5 and the ball seat 6 to adaptively compress the spring 17 to complete the coupling. At the same time, the fixed hook plate 14 will also approach and be inserted into the fixed hook groove 16. When the inclined surface of the fixed hook plate 14 contacts the frame of the fixed hook groove 16, it will be subjected to extrusion force, driving the fixed hook plates 14 on both sides to move in the coupler 2. 2 slides close to each other, compressing spring three 15, until the fixed hook plate 14 is fully inserted into the fixed hook groove 16, the spring three 15 pushes the fixed hook plates 14 on both sides to reset, completing the connection lock fixation of coupler 1 and coupler 2, ensuring the connection stability between coupler 1 and coupler 2, and the set limit ring 301 can make the side of electric contact disc 2 4 and electric contact disc 1 3 close to each other always in stable contact, and there will be no sliding deviation, ensuring the stability of the electrical connection. When disassembling, you only need to press the buckle groove on the fixed hook plate 14 at the same time to drive the fixed hook plates 14 on both sides to move synchronously close to each other, compress the spring three 15, and fix the hook plate 14 It can be detached from the fixed hook groove 16, and disassembly and assembly are convenient. The provided guide rod 17 and perforation 18 are convenient for improving the accuracy of the connection between coupler 1 and coupler 2, avoiding the situation of manual alignment and wasting time, and improving the efficiency of the connection between coupler 1 and coupler 2. When coupler 1 approaches coupler 2, it will also drive the elastic pressure strip 13 to move synchronously. The elastic pressure strip 13 squeezes the pressure plate 10 before the electric contact disc 13 contacts the electric contact disc 24. The pressure plate 10 drives the connecting rod 11 to slide inside the coupler 2, compressing the spring 2 12 and the airbag 9. The gas in the airbag 9 is ejected from the nozzle hole 8, which is convenient for early alignment of the electric contact disc 3 and the electric contact disc 2. The dust on the side where the electric contact discs 2 and 4 are close to each other is cleaned, and the dust that falls off will fall from the opening at the lower end of the limiting ring 301, ensuring the stability of the conductive contact between the electric contact discs 1 and 2, and avoiding the situation where the dust causes poor contact. When the connected coupler 1 and coupler 2 are subjected to a large external pulling force, causing the coupler 1 and coupler 2 to deviate in different directions, the provided spring 1 will adaptively deform forward and backward and left and right, and cooperate with the ball 5 to adaptively roll in the ball seat 6, so that the electric contact discs 2 and 3 will always be stably attached to each other, ensuring the stability of the electrical connection between the coupler 1 and coupler 2;When the guide rod 17 is inserted into the through hole 18, the upper guide rod 17 will contact and push the inclined surface of the fixed inclined plate 19 to rise, and the fixed inclined plate 19 will drive the connecting rod 20 to slide and rise on the support plate 21, compressing the spring 4 22. When the fixed groove 1901 passes the lower side of the fixed inclined plate 19, the spring 4 22 drives the fixed inclined plate 19 and the connecting rod 2 20 to reset, and the lower end of the fixed inclined plate 19 abuts against the upper end of the fixed groove 1901. When the coupler 1 and the coupler 2 are connected, and the electric contact plate 2 4 and the electric contact plate 1 3 are about to contact, the hook bar 32 is pulled upward to drive the fixed The rod plate 25 slides upward on the movable plate 26, compressing the spring five 27. At this time, the lower end of the fixed rod plate 25 will separate from the movable plate 26. After the electric contact disc 1 3 and the electric contact disc 2 4 are in contact and fit, the fixed hole plate 23 on the electric contact disc 2 4 will move between the fixed rod plate 25 and the movable plate 26, loosening the hook strip 32. The spring five 27 drives the fixed rod plate 25 and the hook strip 32 to reset. The fixed rod plate 25 is inserted through the fixed hole plate 23 and fixed. The fixed rod plate 25, the fixed hole plate 23 and the movable plate 26 are all made of conductive materials, contact each other, and form an electrical connection. Then, when the coupler 1 and the coupler 2 are subjected to excessive external force, causing the fixed hook plate 14 and the fixed hook groove 16 to be deformed and separated, the guide rod 17 slides out of the through hole 18, and the fixed inclined plate 19 and the fixed groove 1901 provided cooperate to limit the connection between the coupler 1 and the coupler 2 again to prevent the coupler 1 and the coupler 2 from being separated. At the same time, the electric contact plate 1 and the electric contact plate 2 are separated, and the fixed hole plate 23 has been integrated with the fixed rod plate 25, which will pull the fixed rod plate 25, the movable plate 26, and the wire 28 synchronously to When coupler 1 is disengaged in one direction, wire 28 adaptively unwinds from roller 29 to a certain length, driving roller 29 and shaft 30 to adaptively rotate within slot 24, compressing torsion spring 31. At this point, electrical contact disc 2 4, fixed orifice plate 23, fixed rod plate 25, movable plate 26, wire 28, roller 29, shaft 30, and electrical contact disc 1 3 form an electrical connection. This ensures that coupler 1 and coupler 2 maintain a stable electrical connection even when subjected to significant external force, greatly ensuring the stability of the connection between the couplers.
