Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a reliable power transmission connector. Background Art

[0002] The busbar collector is an important device for collecting electric energy on the collector side of the busbar system. It directly transmits electric energy to the electrical appliances through the sliding contact between the collector brush and the guide rail, thus realizing the mobile power supply of the system.

[0003] The busbar collector is mainly composed of a boot box, a boot sheet, a spring, a collector bracket, a collector support part and other components. During the operation of the busbar collector, the spring is in a compressed state. Under the action of the spring elastic force, the collector brush is in close contact with the inner wall of the guide rail, thereby ensuring good electrical contact between the collector brush and the inner wall of the guide rail, so that the collector can provide a stable current to the electrical appliance. However, since the compression of the spring is the largest in the early stage, the contact force between the collector brush and the inner wall of the guide rail is the largest, and the sliding friction between the collector brush and the guide rail is also the largest, resulting in the largest wear of the collector brush in the early stage. Long-term friction makes it inevitable that the surface of the collector brush will wear. As the contact surface of the collector brush is gradually worn, the spring will gradually stretch, resulting in insufficient elastic force of the spring in the later stage, resulting in the gradual weakening of the tightness of the contact between the collector brush and the guide rail, resulting in the risk of poor contact between the collector brush and the guide rail, and the inability to always ensure stable power supply to the electrical appliance.

[0004] When the collector brush wear exceeds 5mm, it needs to be replaced. Since the wear of the collector brush is closely related to its own material and working environment, the collector brush often suffers from excessive wear before the maintenance time, resulting in insufficient spring elasticity, almost no pressure, increased collector brush resistance, poor contact, etc., which may seriously generate strong electric sparks and cause the collector to burn. The existing collector does not have the function of automatically disengaging the collector brush from the guide rail. In addition, the existing collector brush cannot continue to supply power to the electrical appliance during the replacement process, affecting the normal function of the electrical appliance. Therefore, a reliable power transmission connector is proposed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that, in the process of the collector brush being gradually worn, there is a risk of poor contact between the collector brush and the guide rail, the stable power supply of the electrical appliances cannot be guaranteed at all times, and the existing collector cannot automatically keep the collector brush away from the guide rail, and a reliable power transmission connector is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A reliable power transmission connector, comprising a brush box rotatably connected to a collector bracket and a main collector brush and an auxiliary collector brush symmetrically arranged inside the brush box, the two side walls of the brush box being rotatably provided with a rotating inner cylinder, one end of the rotating inner cylinder being provided with a circular opening arranged opposite to each other, the side walls of the main collector brush and the auxiliary collector brush being fixedly connected with an electric plug shaft arranged through the circular opening, the surface of the rotating inner cylinder being rotatably provided with a transfer outer cylinder, and the inner side of the rotating inner cylinder being provided with a circuit conversion component, so as to facilitate the conversion function of the main collector brush and the auxiliary collector brush to the external circuit electrical connection relationship when the main collector brush and the auxiliary collector brush are converted to each other;

[0008] The outer side wall of the brush box is provided with a switching drive mechanism for driving the main collector brush and the auxiliary collector brush to rotate, and the switching drive mechanism includes a winding wheel rotatably connected to the outer side wall of the brush box, a traction rope wound on the surface of the winding wheel, and a pressure compensation component provided on the outer side wall of the brush box for compensating for insufficient spring elastic force caused by wear of the main collector brush;

[0009] The main collector brush and the auxiliary collector brush form a disc structure with each other, and the contact surface of the main collector brush and the auxiliary collector brush is provided with an insulating layer. The circuit conversion component includes a conductive plug shaft tube plugged with the power plug shaft, and the conductive plug shaft tube is slidably connected to the side wall of the rotating inner cylinder.

[0010] Preferably, a semicircular power connection piece which is in electrical contact with the conductive plug-in shaft tube is fixedly connected to the inner wall of the adapter outer cylinder, and the semicircular power connection piece is connected to an external circuit.

[0011] Preferably, an insulating disassembly rod is slidably provided on the side wall of the adapter outer cylinder, one end of the insulating disassembly rod is fixedly connected to a magnetic block, and the conductive plug-in shaft tube is made of magnetically conductive material, so that the magnetic block magnetically attracts the conductive plug-in shaft tube, thereby separating the conductive plug-in shaft tube from the power plug-in shaft, thereby realizing the disassembly function of the main collector brush and the auxiliary collector brush.

[0012] Preferably, a torsion spring is provided at the connection between the winding wheel and the side wall of the brush box, a concave locking block is fixedly connected to the surface of the rotating inner cylinder, and relatively arranged limiting teeth are fixedly connected to the inner wall of the concave locking block.

[0013] Preferably, the pressure compensation component includes a slidably arranged pressure compensation plate and a rotatably arranged linkage gear, the top end of the pressure compensation plate is fixedly connected with a driven locking tooth plate, the top end of the driven locking tooth plate is fixedly connected with a protrusion that is stuck between adjacent limiting teeth, which is used to better realize the extrusion limiting function of the traction rope and the locking function of the rotating inner cylinder, thereby realizing the locking function of the main collector brush and the auxiliary collector brush, and avoiding the main collector brush and the auxiliary collector brush from rotating during the sliding process.

[0014] Preferably, the driven locking tooth plate and the linkage gear mesh with each other, the outer side wall of the brush box is fixedly connected with a pressure plate, the top end of the pressure plate is fixedly connected with a driving tooth plate, and a pressure spring is arranged between the pressure plate and the driving tooth plate.

[0015] Preferably, an alarm is installed on the outer side wall of the brush box, and a pressure sensor is provided at the connection between the pressure spring and the pressure compensation plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This scheme is provided with a circuit conversion component, a main collector brush and an auxiliary collector brush. When the main collector brush and the auxiliary collector brush alternate with each other, the circuit conversion component can synchronously realize the conversion function of the connection relationship with the external circuit, ensuring that during the alternation of the main collector brush and the auxiliary collector brush, the conductive plug-in shaft tubes on both sides are in contact with the semicircular power connection plate, thereby ensuring that the electrical appliance will not be powered off.

[0018] 2. This scheme is provided with a switching drive mechanism and a pressure compensation component. When the main collector brush is worn, the brush box is slightly moved up under the action of the spring on the inner side of the collector bracket, thereby driving the main brush to slightly move up. At the same time, the pressure plate moves up accordingly and squeezes the pressure spring, so that the pressure spring is compressed, thereby realizing the compensation function of the spring elastic force, thereby ensuring that the contact force between the main collector brush and the inner wall of the guide rail remains unchanged during the wear process, thereby ensuring the stability of the contact between the main collector brush and the guide rail. Compared with the existing spring, it can effectively avoid the phenomenon of excessive wear in the early stage and insufficient contact force in the later stage.

[0019] 3. This scheme is provided with a driven locking tooth plate, a linkage gear and a driving tooth plate. When the upward movement distance of the pressure plate is too large, the driving tooth plate meshes with the linkage gear and drives it to rotate, so that the driven locking tooth plate moves downward, and then the protrusion is separated from the limit teeth, thereby losing the extrusion limit on the traction rope. Under the action of the torsion spring, the winding wheel winds up the traction rope, and then drives the rotating inner cylinder to rotate, realizing the alternating rotation function of the main collector brush and the auxiliary collector brush, so that the auxiliary collector brush temporarily replaces the main collector brush to ensure that during the replacement of the main collector brush, the collector can still supply power to the electrical appliance.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example, see Figures 1 to 6 , a reliable power transmission connector, comprising a brush box 1 rotatably connected to a collector bracket and a main collector brush 2 and an auxiliary collector brush 3 symmetrically arranged inside the brush box 1, a rotating inner cylinder 5 is rotatably arranged on both side walls of the brush box 1, one end of the rotating inner cylinder 5 is provided with a circular opening arranged oppositely, the side walls of the main collector brush 2 and the auxiliary collector brush 3 are fixedly connected with an electric plug shaft 10 arranged through the circular opening, a transfer outer cylinder 4 is rotatably arranged on the surface of the rotating inner cylinder 5, and a circuit conversion component is arranged on the inner side of the rotating inner cylinder 5, so that when the main collector brush 2 and the auxiliary collector brush 3 are converted to each other, the conversion function of the electrical connection relationship between the main collector brush 2 and the auxiliary collector brush 3 and the external circuit is synchronously realized;

[0031] The main collector brush 2 and the auxiliary collector brush 3 form a disc structure with each other, and the contact surface of the main collector brush 2 and the auxiliary collector brush 3 is provided with an insulating layer. The circuit conversion component includes a conductive plug shaft tube 6 which is plugged into the power plug shaft 10, and the conductive plug shaft tube 6 is slidingly connected to the side wall of the rotating inner cylinder 5. The inner wall of the transfer outer cylinder 4 is fixedly connected with a semicircular power connection plate 7 which is in electrical contact with the conductive plug shaft tube 6, and the semicircular power connection plate 7 is connected to the external circuit.

[0032] It should be noted that the semicircular power connection plate 7 is set at an angle of 45 degrees to ensure that when the main collector brush 2 and the auxiliary collector brush 3 are alternating, the conductive plug-in tubes 6 on both sides are in contact with the semicircular power connection plate 7, and the electrical appliances will not be powered off during the alternation process.

[0033] It should be noted that: when the main collector brush 2 and the auxiliary collector brush 3 rotate alternately (that is, the main collector brush 2 and the auxiliary collector brush 3 are in contact with the inner wall of the guide rail), the conductive plug-in shaft tube 6 is driven to rotate. At this time, the conductive plug-in shaft tubes 6 on both sides are in contact with the semicircular power connection plate, and the main collector brush 2 and the auxiliary collector brush 3 simultaneously collect electrical energy to provide current to the electrical appliances. As the main collector brush 2 and the auxiliary collector brush 3 continue to rotate, the main collector brush 2 separates from the inner wall of the guide rail, and the auxiliary collector brush 3 temporarily replaces the main collector brush 2 to collect electrical energy to supply power to the electrical appliances, ensuring that the main collector brush 2 can be detached from the guide rail in time when it is excessively worn, and at the same time ensuring that the collector can still supply power to the electrical appliances during the replacement of the main collector brush 2.

[0034] Furthermore, an insulating disassembly rod 9 is slidingly provided on the side wall of the adapter outer cylinder 4, one end of the insulating disassembly rod 9 is fixedly connected to a magnetic block 8, and the conductive plug-in shaft tube 6 is made of a magnetically conductive material (such as iron), so that the magnetic block 8 magnetically attracts the conductive plug-in shaft tube 6, and then the conductive plug-in shaft tube 6 is separated from the power plug-in shaft 10, thereby realizing the disassembly function of the main collector brush 2 and the auxiliary collector brush 3.

[0035] It should be noted that: the insulating disassembly rod 9 is used to drive the magnetic block 8 to move so that it contacts the conductive plug-in shaft tube 6, and the magnetic attraction is used to drive the conductive plug-in shaft tube 6 to move so that the conductive plug-in shaft tube 6 is separated from the power plug-in shaft 10, thereby realizing the disassembly function of the main collector brush 2 and the auxiliary collector brush 3.

[0036] The outer wall of the brush box 1 is provided with a switching drive mechanism for driving the main collector brush 2 and the auxiliary collector brush 3 to rotate, and the switching drive mechanism includes a winding wheel 11 rotatably connected to the outer wall of the brush box 1, a traction rope 12 wound on the surface of the winding wheel 11, and a pressure compensation component provided on the outer wall of the brush box 1 for compensating for insufficient spring elasticity caused by wear of the main collector brush 2;

[0037] A torsion spring is provided at the connection between the winding wheel 11 and the side wall of the brush box 1, a concave locking block 13 is fixedly connected to the surface of the rotating inner cylinder 5, and a relatively set limiting tooth 1301 is fixedly connected to the inner wall of the concave locking block 13, and a pressure compensation component includes a sliding pressure compensation plate 16 and a rotatable linkage gear 15, and the top of the pressure compensation plate 16 is fixedly connected to a driven locking tooth plate 14, and the top of the driven locking tooth plate 14 is fixedly connected to a protrusion stuck between adjacent limiting teeth 1301, which is used to better realize the extrusion limiting function of the traction rope 12, and at the same time realize the locking function of the rotating inner cylinder 5, and then realize the locking function of the main collector brush 2 and the auxiliary collector brush 3, so as to avoid the main collector brush 2 and the auxiliary collector brush 3 from rotating during the sliding process.

[0038] Furthermore, the driven locking gear plate 14 and the linkage gear 15 mesh with each other, the outer wall of the brush box 1 is fixedly connected with a pressure plate 18, the top of the pressure plate 18 is fixedly connected with a driving gear plate 17, and a pressure spring 19 is arranged between the pressure plate 18 and the driving gear plate 17.

[0039] It is worth noting that the pressure compensation plate 16 is slidably arranged with the external structure, and the rotatably arranged linkage gear 15 is rotatably arranged with the external structure.

[0040] It should be noted that: when the main collector brush 2 is worn during operation, the brush box 1 is slightly moved up under the action of the spring, thereby driving the main brush to slightly move up, and at the same time the pressure plate 18 moves up accordingly, and squeezes the pressure spring 19, so that the pressure spring 19 is compressed. Under the action of the elastic force of the pressure spring 19, the compensation function of the spring elastic force is realized, thereby ensuring that the contact force between the main collector brush 2 and the inner wall of the guide rail remains unchanged during the wear process, thereby ensuring the stability of the contact between the main collector brush 2 and the guide rail. Compared with the existing spring, it can effectively avoid the phenomenon of large wear in the early stage and insufficient contact force in the later stage.

[0041] When the main collector brush 2 is worn too much (the wear amount exceeds 5 mm), the driving tooth plate 17 engages with the linkage gear 15 and drives it to rotate, so that the driven locking tooth plate 14 moves down, and then the protrusion at the top of the driven locking tooth plate 14 is separated from the limiting tooth 1301, thereby losing the squeezing limit on the traction rope 12. Under the action of the torsion spring, the winding wheel winds up the traction rope 12, and then drives the rotating inner cylinder 5 to rotate, realizing the alternating rotation function of the main collector brush 2 and the auxiliary collector brush 3.

[0042] It is worth noting that: there is a large friction between the rotating inner cylinder 5 and the side wall of the brush box 1, so that the torsion spring drives the winding wheel 11 to rotate and reel in the traction rope 12, and drives the rotating inner cylinder 5 to rotate without too fast a speed (to avoid excessive speed, which will cause the main collector brush 2 and the auxiliary collector brush 3 to rotate excessively). When the torsion spring reset force disappears, the main collector brush 2 and the auxiliary collector brush 3 complete the alternation.

[0043] Furthermore, an alarm 20 is installed on the outer side wall of the brush box 1 , and a pressure sensor is provided at the connection between the pressure spring 19 and the pressure compensation plate 16 .

[0044] It should be noted that when the pressure plate 18 moves upward too much, the elastic force of the pressure spring 19 exceeds the threshold of the pressure sensor, the pressure sensor feeds back to the controller, and the controller controls the alarm 20 to sound an alarm, notifying the maintenance personnel to replace the main collector brush 2 in time.

[0045] When the present invention is used, when the main collector brush 2 is worn, the spring on the inner side of the collector bracket will cause the brush box 1 to move up slightly, thereby driving the main brush to move up slightly, and at the same time, the pressure plate 18 moves up accordingly and squeezes the pressure spring 19, so that the pressure spring 19 is compressed. The elastic force generated by the compression of the pressure spring 19 will push the pressure compensation plate 16 upward, thereby acting on the rotating inner cylinder 5. The rotating inner cylinder 5 acts on the main collector brush 2 to achieve the compensation function of the spring elastic force, thereby ensuring that the contact force between the main collector brush 2 and the inner wall of the guide rail remains unchanged during the wear process, thereby ensuring the stability of the contact between the main collector brush 2 and the guide rail. Compared with the existing spring, it can effectively avoid the phenomenon of large wear in the early stage and insufficient contact force in the later stage;

[0046] When the main collector brush 2 is excessively worn, the pressure plate 18 moves upward too much, causing the driving tooth plate 17 to mesh with the linkage gear 15, and driving the linkage gear 15 to rotate, causing the driven locking tooth plate 14 to move downward, thereby causing the protrusion to separate from the limiting tooth 1301, thereby losing the extrusion limit on the traction rope 12. Under the action of the torsion spring, the winding wheel reels the traction rope 12, thereby driving the rotating inner cylinder 5 to rotate, realizing the alternating rotation function of the main collector brush 2 and the auxiliary collector brush 3, so that the main collector brush 2 is separated from the inner wall of the guide rail in time, and the auxiliary collector brush 3 temporarily replaces the main collector brush 2 to collect electrical energy and supply power to the electrical appliances, ensuring that the main collector brush 2 can be separated from the guide rail in time when it is excessively worn, and at the same time ensuring that the collector can still supply power to the electrical appliances during the replacement of the main collector brush 2;

[0047] When the pressure plate 18 moves upward too much, the elastic force of the pressure spring 19 exceeds the threshold of the pressure sensor, and the pressure sensor feeds back to the controller, and the controller controls the alarm 20 to alarm, notifying the maintenance personnel to replace the main collector brush 2 in time;

[0048] Maintenance personnel use the insulating disassembly rod 9 to move the magnetic block 8 so that it contacts the conductive plug-in shaft tube 6, and use the magnetic attraction to move the conductive plug-in shaft tube 6 to separate the conductive plug-in shaft tube 6 from the power plug-in shaft 10, thereby realizing the disassembly function of the main collector brush 2.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
