Description

Technical Field

[0001] This invention relates to the field of electrical engineering technology, specifically a high-current vertical busbar structure with built-in transition connection components and its connection method. Background Technology

[0002] In electrical engineering and other equipment, the connection between high-current vertical busbars and aluminum busbars requires transition connectors to prevent damage due to differences in thermal expansion coefficients. Transition components absorb thermal deformation and vibration stress, preventing fatigue fracture at the connection point and improving system reliability. Transition connectors are typically made of highly conductive materials and silver-plated to ensure extremely low contact resistance. Especially those with elastic structures or flexible connection designs can absorb deformation caused by thermal expansion and contraction and mechanical vibration during equipment operation, avoiding stress concentration, loosening, or even structural damage caused by rigid connections.

[0003] Currently, high-current vertical busbars and transition connectors are generally fixed by bolts or welding. Bolt connection is the most widely used method, especially suitable for scenarios that require disassembly, maintenance or expansion. Although bolt connection makes subsequent disassembly convenient, it requires the use of auxiliary tools. The bolts are tightened after being aligned with the mounting holes, which makes the operation cumbersome and reduces assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a high-current vertical bus structure with a built-in transition connection component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-current vertical bus structure with a built-in transition connection component includes a vertical bus body, on which a transition bus is detachably installed.

[0007] The transition row is provided with at least one set of connecting sleeves, and the vertical row body is provided with a locking pin that engages with the connecting sleeves.

[0008] The latch has multiple locking elements arranged along its circumference, and the locking elements are connected to the elastic compression elements installed in the latch. When the connecting sleeve is inserted into the latch, the locking elements can make way and limit the connecting sleeve.

[0009] A pusher is disposed on the vertical row body. After the elastic squeezing member drives the locking member to unlock the connecting sleeve, the pusher can assist in the separation of the transition row from the vertical row body.

[0010] The high-current vertical busbar structure with built-in transition connection components as described above: a protrusion is formed on the vertical busbar body, a plurality of connection plugs are provided on the protrusion, and a sleeve that is adapted to be inserted into the protrusion is provided on the transition busbar.

[0011] The high-current vertical row structure with a built-in transition connection component as described above: a cylindrical cavity is formed on the inner side of the end of the vertical row body, which is coaxially arranged with the locking pin, and the elastic extrusion member passes through the cylindrical cavity.

[0012] The high-current vertical row structure with a built-in transition connection component as described above: the elastic extrusion member includes a movable disc slidably disposed in the locking pin, a movable rod is provided at one end of the movable disc along the axial direction, a collar is sleeved on the movable rod, and a second spring is provided at the other end of the movable disc, with the two ends of the second spring respectively abutting against the movable disc and the inner end of the locking pin;

[0013] It also includes a drive rod that is rotatably connected to the movable rod, the drive rod passing through the cylindrical cavity and extending out of the vertical row body, and a pressure plate sleeved on the drive rod is provided inside the cylindrical cavity.

[0014] The high-current vertical busbar structure with a built-in transition connection component as described above: a through groove communicating with the cylindrical cavity is formed on the vertical busbar body, at least one set of limiting grooves is formed on the inner wall of the through groove, and a strip block that slides and adapts to the limiting groove is provided on the drive rod.

[0015] The high-current vertical row structure with a built-in transition connection component as described above: the locking member includes a locking block, the locking block is arranged in a wedge shape, and the locking pin is provided with a guide block that is slidably connected to the locking block. One end of the locking block can extend out of the locking pin, and a connecting rod is hinged to the other end. The end of the connecting rod away from the locking block is hinged to the collar.

[0016] The high-current vertical row structure with built-in transition connection components as described above: the pusher includes an extrusion column slidably disposed in the cylindrical cavity, and multiple extrusion columns are disposed along the circumference of the cylindrical cavity, with one end of the extrusion column able to extend out of the cylindrical cavity;

[0017] It also includes a first spring, which is sleeved on the extrusion column. One end of the first spring abuts against the extrusion column, and the other end abuts against the inner end of the cylindrical cavity.

[0018] A connection method for a high-current vertical bus structure with a built-in transition connection component, employing the high-current vertical bus structure with a built-in transition connection component as described above, includes the following steps:

[0019] Step 1: When assembling the vertical strip body and the transition strip, align and insert the protrusions and the sleeve to ensure that the connecting sleeve and the locking pin are smoothly inserted.

[0020] Step 2: When the connecting sleeve and the locking pin are inserted, the connecting sleeve presses against the locking part, and the locking part retracts into the locking pin to allow the connecting sleeve to move. After the connecting sleeve and the locking pin are fully inserted, the elastic potential energy stored in the elastic pressing part presses the locking part to reset and limits the movement of the connecting sleeve.

[0021] Step 3: When the connecting sleeve and the locking pin are unlocked, press the elastic extrusion member to drive the locking member to lock the connecting sleeve. After continuing to press, the connecting sleeve and the locking pin will automatically separate under the push of the pusher.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] When assembling the vertical busbar body and the transition busbar, the connecting sleeve and the locking pin are aligned and inserted. During this process, the connecting sleeve simultaneously compresses multiple locking components. These locking components allow the connecting sleeve to be inserted. After the vertical busbar body and the transition busbar are inserted, the elastic potential energy stored in the elastic compression component can drive the multiple locking components to reset and limit the connecting sleeve. This achieves rapid installation of the vertical busbar body and the transition busbar while ensuring the connection stability between them. The installation process is simple and clear, reducing reliance on highly skilled welders and lowering the risk of secondary damage due to improper operation. The combination of the vertical busbar body and the transition busbar effectively increases the transition contact area, allowing the transition busbar to effectively absorb the thermal expansion stress when the vertical busbar body is energized, preventing the busbar from deforming or breaking due to thermal expansion and contraction.

[0033] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0034] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0035] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0036] Please see Figures 1-8 In this embodiment of the invention, a high-current vertical busbar structure with a built-in transition connection component includes a vertical busbar body 2, on which a transition busbar 1 is detachably installed.

[0037] The transition row 1 is provided with at least one set of connecting sleeves 3, and the vertical row body 2 is provided with a locking pin 4 that engages with the connecting sleeves 3;

[0038] Multiple locking elements are provided along the circumference of the inner side of the locking pin 4, and the locking elements are connected to the elastic extrusion elements installed in the locking pin 4. When the connecting sleeve 3 is inserted into the locking pin 4, the locking elements can make way and limit the connecting sleeve 3.

[0039] A pusher is disposed on the vertical row body 2. After the elastic squeezing member drives the locking member to unlock the connecting sleeve 3, the pusher can assist the separation of the transition row 1 from the vertical row body 2.

[0040] In this embodiment, when the vertical busbar body 2 and the transition busbar 1 are assembled, the connecting sleeve 3 and the locking pin 4 are aligned and inserted. During this process, the connecting sleeve 3 simultaneously squeezes multiple locking components. The locking components can make way for the insertion of the connecting sleeve 3. After the vertical busbar body 2 and the transition busbar 1 are inserted, the elastic potential energy stored in the elastic squeezing component can drive the multiple locking components to reset and limit the connecting sleeve 3. This achieves rapid installation of the vertical busbar body 2 and the transition busbar 1 while ensuring the connection stability of the vertical busbar body 2 and the transition busbar 1. The installation process is simple and clear, reducing the reliance on highly skilled welders and reducing the risk of secondary damage caused by improper operation. The combination of the vertical busbar body 2 and the transition busbar 1 can effectively increase the transition contact area, so that the transition busbar 1 can effectively absorb the thermal expansion stress when the vertical busbar body 2 is energized, preventing the busbar from deforming or breaking due to thermal expansion and contraction.

[0041] In one embodiment, a protrusion 201 is formed on the vertical row body 2, and a plurality of connecting plugs are provided on the protrusion 201. A retainer 101 that is adapted to be inserted into the protrusion 201 is provided on the transition row 1.

[0042] The combination of the bump 201 and the sleeve 101 increases the contact area between the vertical busbar body 2 and the transition busbar 1, significantly increasing the number of metal contact points, thereby reducing contact resistance and heat generation, and ensuring the stability of current transmission. Simultaneously, the large-area bump 201 combined with the sleeve 101 provides stronger mechanical locking force, ensuring the safety of the vertical busbar body 2 under high current and high voltage conditions, and preventing misoperation that could lead to poor contact or detachment between the vertical busbar body 2 and the transition busbar 1.

[0043] As a further embodiment of the present invention, please refer to... Figure 8 The vertical column body 2 has a cylindrical cavity formed on the inner side of its end, which is coaxial with the locking pin 4, and the elastic extrusion member passes through the cylindrical cavity.

[0044] The elastic extrusion member includes a movable disc 8 slidably disposed within the locking pin 4. One end of the movable disc 8 is provided with a movable rod 6 along the axial direction. A collar 7 is sleeved on the movable rod 6. The other end of the movable disc 8 is provided with a second spring 13. The two ends of the second spring 13 abut against the movable disc 8 and the inner end of the locking pin 4, respectively.

[0045] It also includes a drive rod 5 that is rotatably connected to the movable rod 6. The drive rod 5 passes through the cylindrical cavity and extends out of the vertical row body 2. A pressure plate 502 is provided inside the cylindrical cavity and sleeved on the drive rod 5.

[0046] Preferably, the vertical row body 2 has a through groove communicating with the cylindrical cavity, and at least one set of limiting grooves 202 are formed on the inner wall of the through groove. The drive rod 5 is provided with a strip block 501 that is slidably adapted to the limiting groove 202.

[0047] It should be noted that: at least one set of sliding grooves 401 are formed on the inner wall of the locking pin 4, and the movable disk 8 is provided with a slider 801 that is slidably adapted to the sliding grooves 401. Under the restriction of the sliding grooves 401 and the slider 801, the movable disk 8 and the locking pin 4 are slidably connected.

[0048] In this embodiment, when the connecting sleeve 3 and the locking pin 4 are aligned and inserted, the end of the connecting sleeve 3 simultaneously squeezes the locking member. At this time, the strip block 501 on the drive rod 5 aligns with the limiting groove 202, so that when the locking member makes way for the insertion of the connecting sleeve 3, the movable rod 6 moves linearly along the axis of the locking pin 4, so that the movable disc 8 squeezes the second spring 13. The second spring 13 is compressed and stores elastic potential energy until the connecting sleeve 3 and the locking pin 4 are fully inserted. At this time, the locking member loses the squeeze and resets under the elastic action of the second spring 13 and inserts into the inner groove formed by the connecting sleeve 3, so as to realize the limiting of the locking pin 4 on the connecting sleeve 3, ensuring that the locking pin 4 can automatically lock the connecting sleeve 3 while the locking pin 4 and the connecting sleeve 3 are fully inserted, thus ensuring the stable connection between the vertical row body 2 and the transition row 1.

[0049] It should be noted that, in order to prevent the transition row 1 from falling off due to accidental contact with the drive rod 5 after the vertical row body 2 and the transition row 1 are stably connected, the locking component limits the connection sleeve 3 and controls the drive rod 5 to rotate relative to the movable rod 6, so that the strip block 501 and the limiting groove 202 are misaligned. The misalignment mechanism effectively locks the range of motion of the drive rod 5 and prevents misoperation caused by external disturbances.

[0050] As a further embodiment of the present invention, please refer to... Figure 7 and Figure 8 The locking component includes a locking block 9, which is wedge-shaped. The locking pin 4 has a guide block 402 that is slidably connected to the locking block 9. One end of the locking block 9 can extend out of the locking pin 4, and the other end is hinged to a connecting rod 10. The end of the connecting rod 10 away from the locking block 9 is hinged to the collar 7.

[0051] The locking block 9 has an inclined surface at one end facing the pin 4. When the end of the connecting sleeve 3 is inserted, the locking block 9 is subjected to an inclined force. Under the restriction of the guide block 402, the locking block 9 moves linearly along the radial direction of the pin 4. Under the push of the connecting rod 10, the collar 7 is subjected to downward pressure, causing the movable disc 8 to move relative to the inner wall of the pin 4 and to squeeze the second spring 13. After the locking block 9 is completely retracted into the pin 4, when the connecting sleeve 3 moves smoothly to the end of its stroke, the locking block 9 loses the squeeze and resets under the elastic action of the second spring 13. The locking block 9 is inserted into the inner groove of the connecting sleeve 3, so that when the pin 4 and the connecting sleeve 3 are fully inserted, the pin 4 completely locks the connecting sleeve 3, ensuring a stable connection between the vertical row body 2 and the transition row 1.

[0052] As a further embodiment of the present invention, please refer to... Figure 7 The pusher includes a squeezing column 11 slidably disposed in the cylindrical cavity. Multiple squeezing columns 11 are disposed along the circumference of the cylindrical cavity, and one end of the squeezing column 11 can extend out of the cylindrical cavity.

[0053] It also includes a first spring 12, which is sleeved on the extrusion column 11. One end of the first spring 12 abuts against the extrusion column 11, and the other end abuts against the inner end of the cylindrical cavity.

[0054] In this embodiment, when the vertical row body 2 is disassembled from the transition row 1, the control drive rod 5 rotates relative to the movable rod 6, so that the strip block 501 is aligned with the limiting groove 202. The rotation of the drive rod 5 does not affect the movable rod 6. At this time, the drive rod 5 is pressed, and when the drive rod 5 moves, it drives the movable rod 6 to move synchronously, so that the movable disc 8 squeezes the second spring 13. After the locking block 9 releases the limiting of the connecting sleeve 3, the drive rod 5 continues to press. At this time, the pressure plate 502 on the drive rod 5 applies pressure to the squeezing column 11. A disc 301 is formed on the outer wall of the connecting sleeve 3, so that multiple squeezing columns 11 move toward the disc 301 at the same time and squeeze the disc 301. The first spring 12 is compressed, thereby assisting the separation of the connecting sleeve 3 and the locking pin 4, making the separation process of the connecting sleeve 3 and the locking pin 4 easier and reducing the resistance of manual pulling.

[0055] A connection method for a high-current vertical bus structure with a built-in transition connection component, employing the high-current vertical bus structure with a built-in transition connection component as described above, includes the following steps:

[0056] Step 1: When assembling the vertical row body 2 and the transition row 1, align and insert the protrusion 201 with the sleeve 101 to ensure that the connecting sleeve 3 and the locking pin 4 are smoothly inserted.

[0057] Step 2: When the connecting sleeve 3 and the locking pin 4 are inserted, the connecting sleeve 3 squeezes the locking member, and the locking member retracts into the locking pin 4 to make room for the movement of the connecting sleeve 3. After the connecting sleeve 3 and the locking pin 4 are fully inserted, the elastic potential energy stored in the elastic squeezing member squeezes the locking member to reset and limits the connection sleeve 3.

[0058] Step 3: When the connecting sleeve 3 and the locking pin 4 are unlocked, press the elastic extrusion member to drive the locking member to lock the connecting sleeve 3. After continuing to press, the connecting sleeve 3 and the locking pin 4 will automatically separate under the push of the pusher.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
