Description

Technical Field

[0001] The present invention relates to the technical field of electric signal transmission, in particular to a floating connector for rail transit vehicles. Background Art

[0002] Floating connectors for rail vehicles are devices used to connect circuits, air circuits, or electrical systems between couplers on rail vehicles. Primarily used for electrical connections between train couplers, they utilize a spring mechanism to compensate for dynamic deflections during vehicle operation, ensuring stable and reliable electrical contact. Their core function is to automatically adjust contact position through a floating mechanism when the coupler experiences three-dimensional deflections (such as horizontal displacement on the X / Y axes and vertical tilt on the Z axis) due to vibration, turning, braking, and other operating conditions, preventing signal interruption or mechanical damage.

[0003] However, the elastic compensation mechanism of existing connectors usually only acts on the contact part of the plug. When the gap of the coupler changes due to vibration, turning or braking (such as horizontal displacement or vertical tilt), the shear force or axial tension on the plug exceeds the compensation range of the elastic element. The floating mechanism of the connector cannot respond in time due to inertia or friction resistance, resulting in a temporary separation of the contact pair and a sudden change in the coupler gap, which in turn causes the connector signal to be interrupted.

[0004] Furthermore, the floating mechanisms of existing connectors often only support compensation in the X / Y axes, or horizontally. However, three-dimensional coupler offsets, such as vertical tilt along the Z axis, can exceed the compensation range. For example, on a mountain railway, where trains have uneven tracks, vertical connector offset can cause poor contact and lead to connector signal interruption.

[0005] To this end, a floating connector for a rail transit vehicle is proposed. Summary of the Invention

[0006] The object of the present invention is to provide a floating connector for rail transit vehicles to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a floating connector for rail transit vehicles, comprising two mounting plates, each of which is connected to a signal line, a floating connection assembly being commonly provided on the two mounting plates, the floating connection assembly comprising two touch plates, the two touch plates being fixedly connected to one end of the two signal lines close to each other, a moving contact being fixedly connected to a side of one touch plate close to the other touch plate, a touch rod being fixedly connected to a side of the moving contact away from the corresponding touch plate, a fixed contact being fixedly connected to a side of the other touch plate close to the touch rod, and the fixed contact being fixed to a side of the touch plate close to the touch rod. A touch groove is provided on one side of the rod, and a universal ball is movably connected inside each of the two mounting plates. A telescopic tube 1 is fixedly connected to each side of the two touch plates away from each other, a spring 1 is provided inside each of the two telescopic tubes, a spring 2 is sleeved on each of the two signal lines, and a ring plate is fixedly connected to each end of the two signal lines away from each other. Multiple telescopic tubes 2 are hinged in a ring array on each side of the two touch plates away from each other, and the other end of the telescopic tubes 2 is hinged to the mounting plate. A spring 3 is provided inside each of the multiple telescopic tubes 2, and a bellows is fixedly connected to each side of the two touch plates away from each other.

[0008] Furthermore, the moving contact is slidably connected with a slide in a rectangular array, and the moving contact has a square structure. There are four slides in total, and each slide is fixedly connected to two support rods on the side away from the touch plate. There are eight support rods in total. The two support rods on the same slide form a group, and the two support rods in the same group are commonly fixedly connected to a square shaft at one end away from the slide. Two square columns are symmetrically slidably connected to the four square shafts, and a spring four is sleeved on each of the four square shafts. A guide plate is fixedly connected to each of the eight square columns, and a clamping plate is commonly slidably connected to the eight support rods. The clamping plate is fixedly connected to multiple springs five in a rectangular array, and four springs six are fixedly connected to the side of the slide away from the support rod in a rectangular array. Four slot plates are fixedly connected to the moving contact in a rectangular array, and a sealing rubber ring is fixedly connected to the fixed contact.

[0009] Furthermore, the contact rod serves as the signal supply end of the adjacent signal line, that is, the contact rod plays the role of a plug in the floating connector, and the fixed contact serves as the signal receiving end of the adjacent signal line, that is, the contact groove plays the role of a slot in the floating connector, and the groove wall of the contact groove close to the side of the contact rod is set to a shape that gradually expands outward.

[0010] Furthermore, the universal ball can rotate universally inside the mounting plate, the signal line slides inside the universal ball, the two ends of the two telescopic tubes are respectively fixedly connected to the adjacent mounting plate and the side of the touch plate close to each other, the two springs are respectively mounted on the nearby signal lines, and the two ends of the two springs are respectively fixedly connected to the adjacent universal ball and the touch plate.

[0011] Furthermore, two ends of the two springs 2 are fixedly connected to the adjacent universal balls and the ring plate respectively.

[0012] Furthermore, the telescopic tube 2 is configured as two hollow tubes that slide against each other, the end of the telescopic tube 2 away from the touch plate is hinged to the mounting plate, and the two ends of the spring 3 are respectively fixedly connected to the inner walls of the two hollow tubes of the telescopic tube 2 away from each other.

[0013] Furthermore, the two ends of spring four are respectively fixedly connected to the side close to the two square pillars, the guide plate is set to be L-shaped, and the end of the guide plate away from the square pillar is set to be an inclined surface. Four trapezoidal grooves are opened on the card plate in a rectangular array, and the trapezoidal grooves of the card plate are squeezed and adapted to the guide plate. The end of spring five away from the card plate is fixedly connected to the slide plate, and the side of spring six away from the slide plate is fixedly connected to the touch plate.

[0014] Furthermore, two L-shaped grooves are symmetrically opened on the slot plate, and two square columns on the same side are slidingly connected to the two L-shaped grooves of the slot plate. The sealing rubber ring is sleeved on the fixed contact, and one side of the sealing rubber ring extends away from the fixed contact.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The floating connection assembly creates a manipulable, locked connection between the contact rod and the contact slot, preventing connector separation due to coupler changes and maintaining a physical connection between the rod and the slot. Even if the coupler gap changes, causing stress on the external connection, the contact rod and the slot remain physically connected, preventing the risk of disconnection, ensuring a stable electrical connection, and preventing signal interruption.

[0016] Most existing connector floating mechanisms only support X / Y axis compensation. Three-dimensional spatial offsets such as the coupler tilting in the vertical direction of the Z axis may exceed the compensation range. Through the operation of the floating connection assembly, the elastic movable connection between the contact rod and the contact slot relies on the cooperation of the universal ball, spring one, spring three, telescopic tube one, spring three, etc., to provide three-dimensional freedom, allowing the connector to swing in any direction when the coupler is offset, compensating for the compound offset of the X / Y / Z axes, adapting to the multi-angle offset of the coupler, and improving the adaptability of the connector.

[0017] At the same time, through the operation of the floating connection assembly, the sealing rubber ring seals the gap between the fixed contact and the moving contact, preventing water droplets and impurities splashed during the operation of the rail transit vehicle from affecting the connection relationship between the contact rod and the contact groove, thereby ensuring the stability of the signal connection between adjacent carriages of the rail transit vehicle.

[0018] At the same time, through the operation of the floating connection component, when signal transmission needs to be connected between adjacent carriages of a rail transit vehicle, there are on-site conditions such as bumps and shaking that are not conducive to precise insertion. The shape setting of the contact groove can facilitate the connection between the touch rod and the contact groove, achieving an effect similar to blind plugging. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] The present invention provides the following embodiments: See also Figures 1 to 9As shown, a floating connector for rail transit vehicles includes two mounting plates 11, each of which is connected to a signal line 12, and the two signal lines 12 pass through adjacent mounting plates 11. A floating connection component is commonly provided on the two mounting plates 11, and the floating connection component includes two contact plates 21, and the two contact plates 21 are respectively fixedly connected to the ends of the two signal lines 12 that are close to each other. A moving contact 22 is fixedly connected to the side of one contact plate 21 close to the other contact plate 21, and a contact rod 23 is fixedly connected to the side of the moving contact 22 away from the corresponding contact plate 21. The other contact plate 21 is fixed to the side close to the contact rod 23. A fixed contact 24 is connected, and a contact groove 25 is provided on the side of the fixed contact 24 close to the contact rod 23. A universal ball 26 is movably connected inside the two mounting plates 11. A telescopic tube 27 is fixedly connected to each side of the two contact plates 21 away from each other. A spring 28 is provided inside each of the two telescopic tubes 27. A spring 29 is sleeved on each of the two signal lines 12. A ring plate 210 is fixedly connected to each end of the two signal lines 12 away from each other. A plurality of telescopic tubes 211 are hinged in a circular array on each side of the two contact plates 21 away from each other. The other end of the telescopic tube 211 is hinged to the mounting plate 11. Each telescopic tube 21 1 is provided with a spring 3 212 inside. A bellows 213 is fixedly connected to each side of the two contact plates 21 away from each other. A slide plate 214 is slidably connected to the moving contact 22 in a rectangular array. The moving contact 22 has a square structure. There are four slide plates 214. Each slide plate 214 is fixedly connected to two support rods 215 on the side away from the contact plate 21. There are eight support rods 215 in total. The two support rods 215 on the same slide plate 214 form a group. The two support rods 215 in the same group are fixedly connected to a square shaft 216 at one end away from the slide plate 214. Two square columns 217 are symmetrically slidably connected to each of the four square shafts 216. A spring four 218 is sleeved on each of the four square shafts 216, and each spring four 218 is arranged between two square columns 217 on the corresponding square shaft 216. A guide plate 219 is fixedly connected to each of the eight square columns 217. A card plate 220 is slidably connected to the eight support rods 215. A plurality of springs five 221 are fixedly arranged in a rectangular array between the card plate 220 and the slide plate 214. A spring six 222 is fixedly arranged between the side of each slide plate 214 away from the support rod 215 and the contact plate 21. Four slot plates 223 are fixedly connected to the fixed contact 24 in a rectangular array, and a sealing rubber ring 224 is fixedly connected to the fixed contact 24.

[0023] It should be noted that the two mounting plates 11 are respectively mounted on the mating surfaces of the couplers on adjacent carriages of the rail transit vehicle.

[0024] Among them: reference Figure 3 as well as Figures 5 to 8As shown, the contact rod 23 serves as the signal supply end of the adjacent signal line 12, that is, the contact rod 23 plays the role of a plug in the floating connector, and the fixed contact 24 serves as the signal receiving end of the adjacent signal line 12, that is, the contact groove 25 plays the role of a slot in the floating connector. It should be noted that: the groove wall of the contact groove 25 close to the side of the contact rod 23 is set to a shape that gradually expands outward, which plays the role of guiding the contact rod 23 to insert into the contact groove 25. When signal transmission needs to be connected between adjacent carriages of a rail transit vehicle, there are bumps, shaking and other on-site conditions that are not conducive to accurate insertion. The shape setting of the contact groove 25 can facilitate the connection between the contact rod 23 and the contact groove 25, achieving an effect similar to blind plugging.

[0025] It should be added that: when the contact rod 23 is inserted into the contact groove 25, the signal connection between adjacent carriages of the rail transit vehicle is completed.

[0026] Among them: reference Figure 3 、 Figure 6 、 Figure 8 As shown, the universal ball 26 can rotate in all directions inside the mounting plate 11, and the signal line 12 slides inside the universal ball 26. The function of the universal ball 26 is: when the plug-in relationship between the contact rod 23 and the contact groove 25 produces a three-dimensional spatial offset due to working conditions such as vibration, turning, and braking, the signal line 12 can follow the contact rod 23 and the fixed contact 24 to deviate synchronously, and the signal line 12 can always restore the initial connection state, ensuring the transmission accuracy of the signal line 12.

[0027] Among them: reference Figure 3 、 Figure 6 、 Figure 8 As shown, the two ends of the two telescopic tubes 27 are respectively fixedly connected to the adjacent mounting plates 11 and the sides of the touch plates 21 close to each other, and the two springs 28 are respectively sleeved on the adjacent signal lines 12. The two ends of the two springs 28 are respectively fixedly connected to the adjacent universal balls 26 and the touch plates 21. Combined with the above, the universal rotation characteristics of the universal balls 26 and the telescopic characteristics of the telescopic tubes 27 directly act on the two touch plates 21, that is, the plug-in position of the touch rod 23 and the touch groove 25, so that the plug-in of the touch rod 23 and the touch groove 25 also obtains a flexible range of motion in three-dimensional space, that is, a floating connection.

[0028] Among them: reference Figure 3As shown, the two ends of the two springs 29 are fixedly connected to the adjacent universal balls 26 and the ring plate 210 respectively. The function of the springs 29 is as follows: when the plug-in position of the contact rod 23 and the contact groove 25 moves in three-dimensional space, the touch plate 21 drives the signal line 12 to slide inside the universal ball 26, and the springs 29 will produce corresponding elastic deformation, always applying a straight pulling force to the signal line 12, so that no matter how the plug-in position of the contact rod 23 and the contact groove 25 moves, the signal line 12 can always restore the initial connection state, and the signal line 12 can always maintain a close contact with the touch plate 21, that is, the signal line 12 will not be damaged due to the movement of the plug-in position of the contact rod 23 and the contact groove 25, resulting in signal disconnection.

[0029] Among them: reference Figure 4 As shown, the telescopic tube 211 is configured as two hollow tubes that slide against each other. The end of the telescopic tube 211 away from the touch plate 21 is hinged to the mounting plate 11. The two ends of the spring 3 212 are respectively fixedly connected to the inner walls of the ends of the two hollow tubes of the telescopic tube 211 away from each other. The hinge and telescopic characteristics of the telescopic tube 211 have the following functions: similar to the telescopic tube 1 27, it assists the insertion of the touch rod 23 and the touch groove 25 in a flexible range of motion in three dimensions. The functions of the spring 3 212 and the spring 1 28 are: as the The expansion and contraction of the telescopic tube 211 and the telescopic tube 1 27 causes the spring 3 212 and the spring 1 28 to produce elastic deformation accordingly, so that the telescopic tube 211 and the telescopic tube 1 27 can be subjected to a force in the reset direction, so that the plug-in position of the contact rod 23 and the contact groove 25 is offset in three dimensions. This is not only a passive movement, but is also affected by the elastic reset effect of the telescopic tube 211 and the telescopic tube 1 27, so that the plug-in position of the contact rod 23 and the contact groove 25 can return to the initial position after being subjected to external force, thereby ensuring the stability of the connection.

[0030] At the same time, the second telescopic tube 211 and the first telescopic tube 27 transform mechanical vibration energy into elastic potential energy through elastic deformation, thereby reducing the vibration directly transmitted to the plugging position of the contact rod 23 and the contact groove 25.

[0031] Among them: reference Figure 3 、 Figure 4 As shown, the function of the bellows 213 is to assist the deflection of the touch panel 21 relative to the mounting plate 11, while protecting the structure between the touch panel 21 and the mounting plate 11, preventing the structure between the touch panel 21 and the mounting plate 11 from being damaged, resulting in damage to signal transmission between adjacent carriages of the rail transit vehicle.

[0032] Among them: reference Figure 9 As shown, the two ends of the spring four 218 are fixedly connected to the sides close to the two square pillars 217 respectively.

[0033] Among them: reference Figure 9As shown, the guide plate 219 is set to be L-shaped, and the end of the guide plate 219 away from the square column 217 is set to be an inclined surface. Four trapezoidal grooves are opened on the card plate 220 in a rectangular array. The trapezoidal grooves of the card plate 220 are squeezed and adapted to the guide plate 219. The end of the spring five 221 away from the card plate 220 is fixedly connected to the slide plate 214, and the side of the spring six 222 away from the slide plate 214 is fixedly connected to the touch plate 21. Specifically: when the user pushes the card plate 220 to move toward the guide plate 219, the spring five 221 is driven to elastically stretch, and at the same time, the trapezoidal groove wall of the card plate 220 squeezes the inclined surface of the guide plate 219, so that the two guide plates 219 in the same group are driven to move together, and then the two guide plates 219 drive the two square columns 217 to move together on the square shaft 216, and elastically compress the spring four 218 in the process.

[0034] It should be added that: Figure 8 As shown, there are two L-shaped grooves symmetrically provided on the groove plate 223, which are divided into a vertical groove and a horizontal groove, and the two square columns 217 on the same side are slidably connected to the two L-shaped grooves of the groove plate 223. Specifically, when the two square columns 217 are driven to gather together and move to the innermost side, that is, the card plate 220 moves to make the innermost groove wall of the trapezoidal groove contact the two guide plates 219, the card plate 220 is kept in the state of being toggled. At this time, the user can push the slide plate 214 to one side of the groove plate 223 to move, so that the spring six 222 is elastically stretched, and at the same time, the two square columns 217 slide into the L-shaped groove of the groove plate 223. When the two square columns 217 slide to the corner of the L-shaped groove of the groove plate 223, the user no longer pushes the card plate 220. Under the elastic contraction action of the spring five 221, the card plate 220 is pulled in the direction away from the groove plate 223, thereby The trapezoidal groove wall of the card plate 220 no longer squeezes the two guide plates 219, and the two guide plates 219 no longer push the corresponding square columns 217. Under the elastic extension action of the fourth spring 218, the two square columns 217 move away from each other in the L-shaped groove of the groove plate 223, that is, enter the innermost side of the horizontal groove of the L-shaped groove of the groove plate 223. Since the slide plate 214 can only move in a straight line under the sliding limit action of the moving contact 22, the two square columns 217 cannot move out from the inside of the groove plate 223 at this time. At the same time, since the square columns 217, groove plate 223 and other structures are arranged in a rectangular linear array on the moving contact 22, the fixed contact 24 and the moving contact 22 are limited and fixed by the limiting relationship between the four groups of groove plates 223 and the square columns 217. That is, at this time, the plug-in relationship between the contact rod 23 and the contact groove 25 is locked, and at the same time, the elastic extension state of the sixth spring 222 is locked.

[0035] It should be noted that the role of spring five 221 in this process is: in addition to pulling the card plate 220 to reset, it can also prevent the abnormal movement of the card plate 220 when it is not needed to contact the guide plate 219 due to vibration, turning, braking and other working conditions during the operation of the rail transit vehicle, thereby ensuring that the plug-in relationship between the contact rod 23 and the contact groove 25 is firmly locked.

[0036] It should be added that: Figure 5 As described, the sealing rubber ring 224 is sleeved on the fixed contact 24, and one side of the sealing rubber ring 224 extends in the direction away from the fixed contact 24. Its function is: when the fixed contact 24 and the opposite surface of the moving contact 22 are in contact, the sealing rubber ring 224 seals the gap at the contact point between the fixed contact 24 and the moving contact 22, preventing water droplets and impurities splashed during the operation of the rail transit vehicle from affecting the connection relationship between the contact rod 23 and the contact groove 25, thereby ensuring the stability of the signal connection between adjacent carriages of the rail transit vehicle.

[0037] When the rail transit vehicle is parked and the adjacent carriages of the rail transit vehicle need to be unlocked, the user can push the card plate 220 in the direction of the slot plate 223, so that the trapezoidal groove of the card plate 220 squeezes the guide plate 219, so that the two square columns 217 gather and move in the L-shaped groove of the slot plate 223. When the two square columns 217 move to the corner in the L-shaped groove of the slot plate 223, under the elastic contraction action of spring six 222, the slide plate 214 drives the two square columns 217 to disengage from the L-shaped groove of the slot plate 223 through the support rod 215 and the square shaft 216. At this time, the fixed contact 24 and the moving contact 22 are unlocked, and the contact rod 23 can be pulled out from the inside of the contact groove 25.

[0038] In summary, through the operation of the floating connection assembly, the connection between the touch rod 23 and the contact groove 25 can be flexibly moved in three-dimensional space, and when the touch rod 23 is connected to the contact groove 25, it is limited and fixed by the connection relationship between the square column 217 and the slot plate 223, so that the signal connection between adjacent carriages of the rail transit vehicle will not be disconnected.

[0039] In summary, the following beneficial effects can be achieved through the operation of the floating connection component: Existing connectors have elastic compensation mechanisms that only act on the plug contact area. When the coupler gap changes, the plug is subjected to significant shear or axial tension, which can easily cause the contacts to temporarily separate and interrupt the signal. The floating connection assembly, however, creates a controllable locking connection between the contact rod 23 and the contact slot 25, preventing plug separation due to coupler changes and forcing the contact rod 23 and the contact slot 25 to remain physically connected. Even if changes in the coupler gap cause stress on the external connection area, the contact rod 23 and the contact slot 25 will not separate due to relative displacement, fundamentally eliminating the risk of contact disconnection, ensuring a stable electrical connection, and preventing signal interruption.

[0040] Most existing connector floating mechanisms only support X / Y axis compensation. Three-dimensional spatial offsets such as the coupler tilting in the vertical direction of the Z axis may exceed the compensation range. Through the operation of the floating connection assembly, the elastic movable connection between the touch rod 23 and the touch slot 25 relies on the cooperation of the universal ball 26, spring 1 28, spring 3 212, telescopic tube 1 27, spring 3 212, etc., providing three-dimensional freedom, allowing the connector to swing in any direction when the coupler is offset, compensating for the composite offset of the X / Y / Z axes, adapting to the multi-angle offset of the coupler, and improving the adaptability of the connector.

[0041] At the same time, through the operation of the floating connection assembly, the sealing rubber ring 224 seals the gap between the fixed contact 24 and the moving contact 22, preventing water droplets and impurities splashed during the operation of the rail transit vehicle from affecting the connection relationship between the contact rod 23 and the contact groove 25, thereby ensuring the stability of the signal connection between adjacent carriages of the rail transit vehicle.

[0042] At the same time, through the operation of the floating connection component, when plug-in signal transmission is required between adjacent carriages of a rail transit vehicle, there are on-site conditions such as bumps and shaking that are not conducive to precise insertion. The shape setting of the contact groove 25 can facilitate the plug-in of the contact rod 23 and the contact groove 25, realizing a function similar to blind plug-in.
