Description

Technical Field

[0001] This invention relates to the field of transformer terminal technology, and specifically proposes a transformer terminal structure. Background Technology

[0002] The terminal structure of a transformer is a key component connecting the internal windings to the external circuit. Its design must meet the requirements of electrical insulation, mechanical strength and temperature rise. It can be divided into bolt-type terminal blocks, plug-in terminal blocks, etc. Among them, plastic bolt-connection terminal blocks are usually used in transformer scenarios with low voltage, low power and stable environmental conditions. Its characteristics are low cost and light weight.

[0003] When using a plastic bolt-connected terminal block for wiring, first loosen the screws on the terminal block, then place the wire end on the terminal block and tighten the screws to secure the terminal, thus completing the connection between a single line and the terminal block.

[0004] However, plastic bolt-connected terminal blocks have the following problems during use: 1. The installation of wires is inconvenient, and the wiring is cumbersome when there are many wires; 2. When wiring individually, due to the large number of wires, wiring fatigue often leads to inaccurate placement and unstable fixing of some wire terminals, resulting in loosening and poor wire contact; 3. If only a unified fixing method is used for multiple wires, it is difficult to disassemble and replace a single wire when it needs to be replaced during use. Even if the existing terminal structure can achieve this, its structure is complex.

[0005] Therefore, there is an urgent need for a transformer terminal structure. Summary of the Invention

[0006] In view of the above problems, embodiments of the present invention provide a transformer terminal structure to solve the technical problems in the related art.

[0007] To achieve the above objectives, embodiments of the present invention provide the following technical solution: a transformer terminal structure, comprising: a mounting base, a wire clamping mechanism, a limiting part, and an integrated drive mechanism.

[0008] The mounting base consists of a fixed box and multiple isolation stations provided thereon. The fixed box has baffles installed on both sides along its length and a partition installed in the middle along its width. Each side of the partition has a card plate connected to the fixed box and evenly arranged along the length of the partition. Isolation stations are formed between two adjacent card plates and between a card plate and an adjacent baffle.

[0009] The wire clamping mechanism includes multiple conductive plates 1 installed on the top of the fixed box and penetrating the partition. The multiple conductive plates 1 are evenly arranged along the length of the fixed box. A conductive plate 2 is provided on the isolation station through an elastic sliding part. The conductive plate 2 cooperates with the conductive plate 1 under the action of the elastic sliding part to pre-fix the end of the wire. The fixed box is provided with an independent driving part that drives the elastic sliding part to drive the conductive plate 2 to slide up and down.

[0010] The limiting part is provided on the second conductive plate and the corresponding first conductive plate; the integrated driving mechanism is provided on the fixed box, which is used to drive multiple second conductive plates to slide up and down at the same time to release or fix multiple wires at the same time.

[0011] The two ends of the same conductive plate one are respectively connected by two conductive plates two to clamp and fix the incoming wire and the outgoing wire, and the ends of the wires are equipped with terminals.

[0012] The independent drive unit, in conjunction with the integrated drive mechanism, can drive a single corresponding conductive plate 2 to move up and down, or drive multiple conductive plates 2 to move up and down synchronously.

[0013] In one possible implementation, the integrated drive mechanism includes a lifting seat that is slidably mounted up and down inside a fixed box. The lifting seat consists of multiple horizontally connected I-shaped seats and two storage boxes mounted on the bottom of the I-shaped seats. A lifting drive unit that drives the lifting seat to move up and down is installed inside the fixed box.

[0014] In one possible implementation, the elastic sliding part includes a plug-in frame, which is frame-shaped and has two vertical sections that are slidably plugged into both sides of the first conductive plate in the width direction. The second conductive plate is installed inside the plug-in frame and is located above the first conductive plate. After the plug-in frame is slidably inserted into the fixing box, a connecting plate is slidably connected to the vertical section. A return spring is installed between the connecting plate and the lower horizontal section of the plug-in frame. A guide plate that is slidably connected to the corresponding storage box is installed on the side wall of the connecting plate.

[0015] In one possible implementation, the limiting part includes a groove in the middle of the conductive plate two, and limiting posts corresponding to the grooves are installed on the conductive plate one. The wire end (with an existing structure and a round hole in the middle) is fitted onto the limiting post. When the conductive plate two moves down, the upper end of the limiting post is inserted into the groove to prevent the wire end from disengaging from the limiting post, thereby limiting the end of the wire.

[0016] In one possible implementation, the independent drive unit includes an adjustment rod rotatably connected to a storage box, which slides through an I-shaped base, a fixed box, and a conductive plate. The adjustment rod is connected to a guide plate by a threaded connection, and a pressure post is installed on the lower end face of the connecting plate.

[0017] In one possible implementation, the lifting drive unit includes two inclined plates symmetrically arranged along its length direction mounted on the top of the lifting seat, a fixed seat installed between the two inclined plates, two symmetrically arranged racks mounted on the lower end face of the fixed seat, two connecting shafts rotatably connected inside the fixed box, the two connecting shafts being located between the two racks, gears fixedly sleeved on both connecting shafts, and the two gears meshing and driving each other, the two gears meshing and driving each other with the adjacent racks, and a rotation locking assembly for driving one of the connecting shafts to rotate is installed on the fixed box.

[0018] In one possible implementation, the rotary locking assembly includes a locking rod rotatably connected to the mounting box via a threaded engagement, the locking rod being slidably inserted into one of the connecting shafts via a spline engagement.

[0019] In one possible implementation, a connecting vertical plate is installed between the inclined plate and the top of the corresponding I-shaped base below it, and the inclined plate, multiple connecting vertical plates, and lifting base form multiple triangles.

[0020] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: 1. The transformer terminal structure designed in the present invention, through the cooperation of the wire clamping mechanism, the limiting part and the integrated drive mechanism, realizes the functions of pre-fixing, accurate limiting, integrated pressure locking of multiple wires and individual disassembly when wiring wires. It not only makes the bolt terminal uniformly fixed when wiring wires, but also does not affect the individual disassembly of each wire. At the same time, it avoids the problem of poor contact caused by wiring fatigue due to too many wires connected, which greatly improves the firmness and convenience of wire wiring. Moreover, the wire clamping mechanism, the limiting part and the integrated drive mechanism have a simple structure and are easy to operate.

[0021] 2. When wiring wires, this invention only requires pulling the elastic sliding part to move the corresponding conductive plate two upwards, so that the conductive plate two is far away from the conductive plate one. Then, the wire end is inserted between the conductive plate two and the conductive plate one, and the wire end is limited by the limiting part, which can achieve the pre-fixing effect of the wire end, greatly improving the convenience and efficiency of wire wiring.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figure 1 and Figure 7 A transformer terminal block structure includes: a mounting base 1, a wire clamping mechanism 2, a limiting part 3, and an integrated drive mechanism 4.

[0035] See Figure 1 and Figure 7 The mounting base 1 consists of a fixed box 10 and a plurality of isolation stations 11 provided thereon. The fixed box 10 has baffles 12 installed on both sides in the length direction and a partition 13 installed in the middle in the width direction. Both sides of the partition 13 are provided with card plates 14 that are connected to the fixed box 10 and are evenly arranged along the length direction of the partition 13. An isolation station 11 is formed between two adjacent card plates 14 and between the card plates 14 and the adjacent baffles 12.

[0036] See Figure 1 , Figure 7 and Figure 8 The wire clamping mechanism 2 includes multiple conductive plates 20 installed on the top of the fixed box 10 and passing through the partition 13. The multiple conductive plates 20 are evenly arranged along the length of the fixed box 10. A conductive plate 23 is provided on the isolation station 11 through an elastic sliding part 22. Under the action of the elastic sliding part 22, the conductive plate 23 cooperates with the conductive plate 20 to pre-fix the end of the wire 5. The conductive plate 20 and the two conductive plates 23 cooperate to connect the two wires 5. The fixed box 10 is provided with an independent driving part 24 that drives the elastic sliding part 22 to drive the conductive plate 23 to slide up and down.

[0037] See Figure 1 , Figure 7 and Figure 8 The limiting part 3 is provided on the conductive plate 23 and the corresponding conductive plate 20; the integrated driving mechanism 4 is provided on the fixed box 10, which is used to drive multiple conductive plates 23 to slide up and down at the same time to release or fix multiple wires 5 at the same time; the two ends of the same conductive plate 20 are respectively pressed and fixed by two conductive plates 23 to connect the incoming wire 5 and the outgoing wire 5, and the end of the wire 5 is equipped with a terminal.

[0038] When fixing the connector of wire 5, first pull the elastic sliding part 22 to move the corresponding conductive plate 23 upward, so that the conductive plate 23 is away from the conductive plate 20. Then, insert the connector of wire 5 between the conductive plate 23 and the conductive plate 20, and limit the connector of wire 5 through the limiting part 3, so that the conductive plate 23 and the conductive plate 20 can accurately and stably fix the connector of wire 5, preventing some wires 5 from being unstable due to fatigue caused by a large number of wires. Then, release the elastic sliding part 22. Under the elastic reset action of the elastic sliding part 22, the conductive plate 23 moves downward with the elastic sliding part 22, thereby pressing the connector of wire 5 against the conductive plate 20, realizing the pre-fixing function of the end of wire 5.

[0039] Then, the remaining wires 5 are pre-fixed in sequence. After all the wires 5 are pre-fixed, the integrated drive mechanism 4 drives multiple elastic sliding parts 22 to move down synchronously and lock, so that the elastic sliding parts 22 drive multiple conductive plates 23 to press and fix multiple wires 5 onto the corresponding conductive plates 20, thereby achieving unified locking and fixing of multiple wires 5. This avoids the problems of cumbersome wiring and low efficiency caused by the large number of wires when connecting multiple wires 5 with traditional bolt terminals.

[0040] When a single set of conductors 5 needs to be inspected or disassembled, the corresponding independent drive unit 24 drives the corresponding elastic sliding part 22 to move upward, and the elastic sliding part 22 drives the conductive plate 23 connected to it to move upward, thereby loosening the corresponding conductor 5 and realizing the function of individual disconnection and connection. This allows the conductors 5 to be disconnected and connected independently or uniformly, greatly improving the convenience and efficiency of connecting the transformer conductors 5.

[0041] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The integrated drive mechanism 4 includes a lifting seat 40 that is slidably installed inside a fixed box 10. The lifting seat 40 is composed of multiple horizontally connected I-shaped seats 45 and two storage boxes 41 installed at the bottom of the I-shaped seats 45. A lifting drive unit 42 that drives the lifting seat 40 to move up and down is installed inside the fixed box 10.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The elastic sliding part 22 includes a plug-in frame 220, which is frame-shaped and has two vertical sections that are slidably plugged into both sides of the first conductive plate 20 in the width direction. The second conductive plate 23 is installed inside the plug-in frame 220 and is located above the first conductive plate 20. After the plug-in frame 220 is slidably inserted into the fixing box 10, a connecting plate 221 is slidably connected to the vertical section. A return spring 222 is installed between the connecting plate 221 and the lower horizontal section of the plug-in frame 220. A guide plate 224 that is slidably connected to the corresponding storage box 41 is installed on the side wall of the connecting plate 221.

[0043] When pre-fixing the wire 5, pull the connector 220 upward. The connector 220 drives the conductive plate 23 upward. When the connector 220 moves upward, it pulls the return spring 222 to compress it. Then, insert the terminal of the wire 5 between the conductive plate 23 and the conductive plate 20, and limit the terminal of the wire 5 through the limiting part 3. Then, release the connector 220, so that the connector 220 drives the conductive plate 23 downward under the elastic force of the return spring 222, pre-pressing the end of the wire 5. The conductors 5 are fixed on the conductive plate 20 to achieve the effect of pre-fixing. After all the conductors 5 are pre-fixed, the lifting drive unit 42 drives the lifting seat 40 downward. The lifting seat 40, through the elastic sliding part 22 and the independent drive unit 24, drives the multiple conductive plates 23 to move down and lock, so that all the conductors 5 are uniformly pressed and fixed on the corresponding conductive plates 23, realizing the unified and integrated wiring fixation of multiple conductors 5, improving the efficiency and convenience of wiring conductors 5.

[0044] See Figure 7 and Figure 8 The limiting part 3 includes a groove 30 in the middle of the conductive plate 23. The conductive plate 20 is equipped with a limiting post 31 corresponding to the groove 30. The wire 5 connector (which is an existing structure with a round hole in the middle) is fitted onto the limiting post 31. When the conductive plate 23 moves down, the upper end of the limiting post 31 is inserted into the groove 30 to prevent the wire 5 connector from detaching from the limiting post 31, thereby limiting the end of the wire 5.

[0045] See Figure 2 , Figure 4 and Figure 7 The independent drive unit 24 includes an adjustment rod 240 rotatably connected to the storage box 41, which has a sliding through I-shaped base 45, a fixed box 10, and a conductive plate 20. The adjustment rod 240 is connected to the guide plate 224 by a threaded connection, and a pressure post is installed on the lower end face of the connecting plate 221.

[0046] When the unified locking is achieved, the lifting drive unit 42 drives the lifting seat 40 to move downward. The lifting seat 40 drives the storage box 41, guide plate 224, and adjusting rod 240 to move downward. The guide plate 224 and connecting plate 221 pull the plug frame 220 downward by squeezing the reset spring 222, so that the conductive plate 23 presses and fixes the end of the wire 5. When the pressing post on the connecting plate 221 abuts against the lower horizontal section of the plug frame 220, the plug frame 220 and the conductive plate 23 are locked.

[0047] When disconnecting the wire independently, rotate the corresponding adjusting rod 240. The adjusting rod 240, through its threaded engagement with the guide plate 224, drives the guide plate 224 and the connecting plate 221 to move upward. As the connecting plate 221 moves upward, it stops pressing the return spring 222, causing the return spring 222 to reset. Then, the corresponding plug bracket 220 can be pulled upward, causing the conductive plate 23 to move away from the conductive plate 20, and the corresponding wire 5 can be removed, thus realizing the function of disconnecting and reconnecting a single wire.

[0048] See Figure 4 , Figure 5 and Figure 6 The lifting drive unit 42 includes two inclined plates 420 symmetrically arranged along the length direction mounted on the top of the lifting seat 40. A fixed seat 421 is installed between the two inclined plates 420. Two racks 422 symmetrically arranged are installed on the lower end face of the fixed seat 421. Two connecting shafts 423 are rotatably connected inside the fixed box 10. The two connecting shafts 423 are located between the two racks 422. Gears 424 are fixedly sleeved on both connecting shafts 423, and the two gears 424 mesh and drive each other. The two gears 424 mesh and drive each other with the adjacent racks 422. A rotation locking assembly for driving one of the connecting shafts 423 to rotate is installed on the fixed box 10.

[0049] See Figure 5 and Figure 6 The rotary locking assembly includes a locking rod 430 that is rotatably connected to the fixed box 10 via a threaded connection, and the locking rod 430 is slidably inserted into one of the connecting shafts 423 via a spline connection.

[0050] When locking uniformly, the locking lever 430 is rotated. During the rotation, the locking lever 430 moves axially through its threaded connection with the fixed box 10. At the same time, the locking lever 430 drives the connecting shaft 423 to rotate through the spline connection between the locking lever 430 and the corresponding connecting shaft 423. The two connecting shafts 423 rotate simultaneously under the meshing transmission of the gear 424. Meanwhile, the gear 424 drives the fixed seat 421 to move downward through the meshing transmission with the corresponding rack 422. The fixed seat 421 presses against the lifting seat 40 to move downward through the two inclined plates 420. The lifting seat 40 drives the guide plate 224, the connecting plate 221 and the plug-in bracket 220 to move downward, so that multiple conductive plates 223 move downward synchronously to press and fix multiple wires 5, thereby achieving uniform fixation of multiple wires 5.

[0051] See Figure 4 and Figure 6A connecting vertical plate 440 is installed between the inclined plate 420 and the top of the corresponding I-shaped seat 45 below it. The inclined plate 420, multiple connecting vertical plates 440 and lifting seat 40 form multiple triangles, thereby making multiple triangles on both sides of the fixed seat 421. During the downward movement of the fixed seat 421, the inclined plate 420 is driven to press against the lifting seat 40, so that each I-shaped seat 45 in the lifting seat 40 receives uniform pressure, improving the pressure and fixing stability of each conductive plate 23 and the corresponding wire 5.

[0052] See Figures 1-8 In specific operation, firstly, the elastic sliding part 22 is pulled to move the corresponding conductive plate 23 upward, so that the conductive plate 23 is away from the conductive plate 20. Then, the terminal of the wire 5 is inserted between the conductive plate 23 and the conductive plate 20, and the terminal of the wire 5 is limited by the limiting part 3, so that the conductive plate 23 and the conductive plate 20 can accurately and stably fix the terminal of the wire 5. Then, the elastic sliding part 22 is released, and the conductive plate 23 moves downward with the elastic sliding part 22 under the elastic force of the elastic sliding part 22, thereby pressing the terminal of the wire 5 against the conductive plate 20, realizing the pre-fixing function of the end of the wire 5.

[0053] Then, the wires 5 are pre-fixed sequentially. After all the wires 5 are pre-fixed, the integrated drive mechanism 4 drives multiple elastic sliding parts 22 to move down synchronously and lock them, so that the elastic sliding parts 22 drive multiple conductive plates 23 to press and fix multiple wires 5 onto the corresponding conductive plates 20, thereby achieving unified locking and fixing of multiple wires 5.

[0054] When it is necessary to inspect or disassemble a single set of wires 5, the corresponding independent driving part 24 drives the corresponding elastic sliding part 22 to move upward, and the elastic sliding part 22 drives the conductive plate 23 connected to it to move upward, thereby loosening the corresponding wires 5 and realizing the function of disconnecting the wires individually.
