Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and specifically to a transformer based on a quick pluggable winding connection structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Common transformers include an oil tank, windings, and bushings installed on the top of the oil tank. Conductive rods are generally installed inside the bushings, and the windings are connected to the corresponding conductive rods through leads.

[0003] Existing ones are generally fixed on the top of the oil tank by means of bolt connection. Since multiple groups of bushings are usually installed on each oil tank, and each bushing requires multiple bolts to achieve a firm connection. When installing and replacing the bushings, the installation and removal of the bolts take a lot of time, affecting the efficiency of the installation and replacement of the bushings; in addition, the conductive rods are generally connected to the leads of the windings by welding or bolt connection. When replacing, the separation of the conductive rods from the leads also takes a lot of time, further affecting the efficiency of the installation and replacement of the bushings. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a transformer based on a quick pluggable winding connection structure, which includes an oil tank, windings installed inside the oil tank and provided with leads, and a number of bushings located above the oil tank and internally fixedly connected with conductive rods.

[0005] The plugging mechanism includes a gland fixedly connected to the bottom of the bushing. A plug is fixedly connected to the bottom of the horizontal part of the gland. Limiting grooves are opened on both the left and right sides of the plug, and clamping plates are hinged to both the left and right sides of the gland.

[0006] The bottom end of the bushing extends to the bottom of the plug and is then fixedly connected with a second connection head.

[0007] The connection mechanism includes a first mounting seat fixedly installed on the oil tank and having a jack opened in the middle. Clamping blocks that are clamped and matched with the corresponding clamping plates are fixedly connected to both the left and right sides of the first mounting seat. Wedge-shaped blocks one and a first moving component that are used to lock the plug and are symmetric left and right are slidably installed inside the first mounting seat.

The top of the lead extends to the inside of the second mounting seat and is then fixedly connected with a first connection head that is plugged and matched with the second connection head. Wedge-shaped blocks two and a second moving component that are used to lock the second connection head and are symmetric left and right are slidably installed inside the second mounting seat.

[0009] In a possible implementation manner, the first connector head is composed of two U-shaped terminals combined. The second connector head is in an inverted U shape. The two vertical segments of the second connector head are respectively inserted and matched with the corresponding terminals. Through holes one are opened on the opposite sides of the two terminals, and through holes two are opened on the two vertical segments of the second connector head.

[0010] In a possible implementation manner, wedge-shaped bumps are fixedly connected to the opposite sides of the two terminals, and a tightening block located between the two vertical segments is fixedly connected to the bottom of the horizontal segment of the second connector head.

[0011] In a possible implementation manner, the first moving component includes a pushing block one slidably installed left and right inside the first mounting seat. One side of the pushing block one close to the center of the first mounting seat is fixedly connected to the corresponding first wedge-shaped block, and a first return spring is fixedly connected between the side of the pushing block one away from the center of the first mounting seat and the inner wall of the first mounting seat.

[0012] In a possible implementation manner, the second moving component includes a pushing block two slidably installed left and right inside the second mounting seat. One side of the pushing block two close to the center of the second mounting seat is fixedly connected to the corresponding second wedge-shaped block and abuts against the corresponding terminal, and a second return spring is fixedly connected between the side of the pushing block two away from the center of the second mounting seat and the inner wall of the connecting mechanism.

[0013] In a possible implementation manner, unlocking components one and two for unlocking the first wedge-shaped block and the second wedge-shaped block are respectively installed inside the first mounting seat and the second mounting seat. The unlocking component one includes movable rods slidably installed up and down inside the first mounting seat and symmetrically distributed left and right. The movable rods are in an inverted L shape. A wedge-shaped groove for the movable rods to move up and down through is opened on the pushing block one. A wedge-shaped insertion block is fixedly connected to the side of the vertical segment of the movable rod away from the center of the first mounting seat. The wedge-shaped insertion block is slidably inserted and matched with the inclined surface of the corresponding wedge-shaped groove. A third return spring is fixedly connected between the bottom of the horizontal segment of the movable rod and the inner wall of the first mounting seat. The unlocking component two has the same structure as the unlocking component one and the movable rods of the two are fixedly connected.

[0014] In a possible implementation manner, a linkage component is further included. The linkage component includes a sealing partition slidably installed up and down inside the first mounting seat. The horizontal segment of the movable rod in the unlocking component one is fixedly connected to the inner wall of the sealing partition. Pushing blocks symmetrically distributed left and right are fixedly connected to the outer ring wall of the sealing partition. The pushing blocks are slidably connected to the first mounting seat up and down and the ends thereof away from the center of the first mounting seat extend to the outside of the first mounting seat.

[0017] Advantages of the present invention: 1. Through the mutual cooperation of the connection mechanism and the plugging mechanism, the sleeve can be connected to the fuel tank in a plugging manner. After the plug is inserted into the jack, the second connector can be plugged and connected to the first connector. At this time, the first wedge block and the second wedge block can automatically lock the plug and the second connector. At the same time, the clamping plate can be clamped with the clamping block to achieve secondary locking of the plug, improve the firmness of the sleeve installation, and facilitate the rapid connection between the sleeve and the winding.

[0018] 2. When the clamping plate is clamped with the clamping block, the clamping plate can block the window, prevent the movable rod from exposing to the outside of the gland, prevent accidental touch, and the stop bar on the clamping plate can also block and limit the movable rod to prevent the movable rod from moving downward, further avoiding accidental unlocking of the first unlocking component and the second unlocking component, and ensuring the firm locking of the first wedge block and the second wedge block.

Detailed implementation manners

[0029] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0030] Please refer to Figures 1-3 , a transformer based on a fast pluggable winding connection structure, including a fuel tank 1, a winding 2 installed inside the fuel tank 1 and provided with a lead wire 21, a plurality of bushings 3 located above the fuel tank 1 and fixedly connected with a conductive rod 31 inside, a plurality of connection mechanisms 4 arranged in a matrix are installed on the top of the fuel tank 1, and a plugging mechanism 5 that is fixedly connected with the connection mechanism 4 in a pluggable manner is fixedly connected to the bottom of the bushing 3.

[0031] Please refer to Figure 2 , Figure 3 and Figure 8 , the plugging mechanism 5 includes a gland 51 fixedly connected to the bottom of the bushing 3, a plug 52 is fixedly connected to the bottom of the horizontal part of the gland 51, limiting grooves 521 are opened on both the left and right sides of the plug 52, snap-in boards 53 are hinged to both the left and right sides of the gland 51, and the bottom end of the bushing 3 extends to the bottom of the plug 52 and is fixedly connected with a connector two 32.

[0032] Please refer to Figure 2 , Figure 3 andFigure 4 The connecting mechanism 4 includes a first mounting seat 41 fixedly installed on the fuel tank 1 and having a jack 411 formed in the middle thereof. On the left and right sides of the first mounting seat 41, there are fixedly connected blocks 412 that are in snap-fit with the corresponding snap-fit plates 53. Inside the first mounting seat 41, there are slidably installed first wedge-shaped blocks 42 and a first moving assembly 43 that are symmetric about the left and right and are used to lock the plug 52. Between the top of the first mounting seat 41 and the horizontal part of the gland 51, there is also installed a sealing ring 6 for sealing.

[0033] Please refer to Figure 2 , Figure 3 and Figure 5 , the bottom of the first mounting seat 41 penetrates through the inside of the fuel tank 1 and is fixedly connected to a second mounting seat 44. The top of the lead wire 21 extends into the inside of the second mounting seat 44 and is fixedly connected to a first connector 22 that is in plug-in fit with the second connector 32. Inside the second mounting seat 44, there are slidably installed second wedge-shaped blocks 45 and a second moving assembly 46 that are symmetric about the left and right and are used to lock the second connector 32.

[0034] Please refer to Figures 1-8 , specifically in use, when installing the sleeve 3, first press the top of the snap-fit plate 53 towards the direction close to the sleeve 3, so that the bottom of the snap-fit plate 53 moves away from the plug 52. Then align the plug 52 with the jack 411 and insert it into the jack 411. At this time, the second connector 32 at the bottom of the plug 52 will be inserted into the first connector 22. During the plugging process, the plug 52 and the second connector 32 respectively push the first wedge-shaped block 42 and the second wedge-shaped block 45 to move away from the center of the first mounting seat 41. When the plug 52 is completely inserted into the jack 411, the first wedge-shaped block 42 will be aligned with the limiting groove 521. Use the first moving assembly 43 to push the first wedge-shaped block 42 towards the center of the first mounting seat 41, so that the first wedge-shaped block 42 is inserted into the limiting groove 521 to fix the plug 52 and prevent the plug 52 from loosening. At the same time, use the second moving assembly 46 to push the second wedge-shaped block 45 towards the center of the second mounting seat 44, so that the second wedge-shaped block 45 locks the second connector 32 by plugging, improving the firmness of the connection between the second connector 32 and the first connector 22.

[0035] After the locking is completed, the horizontal part of the gland 51 presses tightly on the top of the first mounting seat 41. Use the sealing ring 6 to seal the gap between the first mounting seat 41 and the horizontal part of the gland 51 to prevent external impurities from entering the first mounting seat 41.

[0036] Then release the pressing on the top of the snap-fit plate 53, and then push the bottom of the snap-fit plate 53 towards the direction close to the plug 52, so that the bottom of the snap-fit plate 53 is snap-fitted with the block 412 to achieve secondary locking of the plug 52, further improving the firmness of the installation of the sleeve 3.

[0037] Please refer toFigure 3 and Figure 7 The connecting head 22 is composed of two U-shaped terminals. The connecting head 32 is inverted U-shaped. The two vertical segments of the connecting head 32 are respectively inserted and matched with the corresponding terminals. Through holes 221 are formed on the opposite sides of the two terminals. Through holes 321 are formed on the two vertical segments of the connecting head 32. One end of the wedge block 45 close to the center of the mounting seat 44 slides through the corresponding through hole 221.

[0038] Please refer to Figure 3 、 Figure 7 and Figure 8 During specific use, by setting two terminals for connection, when one of the terminals has poor contact, the other terminal can still maintain an effective connection, avoiding power failure. When the vertical segment of the connecting head 32 is completely inserted into the corresponding terminal, the through hole 221 will coincide with the through hole 321. At this time, the wedge block 45 can be inserted into the corresponding through holes 221 and 321, and the wedge block 45 is used to lock the connecting head 22 and the connecting head 32, preventing the connecting head 22 and the connecting head 32 from loosening and ensuring the firmness of the connection between the connecting head 22 and the connecting head 32.

[0039] Please refer to Figure 3 and Figure 7 Wedge-shaped convex blocks 222 are fixedly connected to the opposite sides of the two terminals. The bottom of the horizontal segment of the connecting head 32 is fixedly connected with an insertion block 322 located between the two vertical segments.

[0040] Please refer to Figure 3 、 Figure 7 and Figure 8 During specific use, after the plug 52 is inserted into the jack 411, the two vertical segments of the connecting head 32 are respectively inserted into the corresponding terminals, and the insertion block 322 is inserted between the left and right terminals. When the insertion block 322 contacts the inclined surface at the top of the wedge-shaped convex block 222, the wedge-shaped convex block 222 is pushed by the insertion block 322 to move away from the center of the mounting seat 44, so that the terminal clamps the connecting head 32, avoiding poor contact.

[0041] Please refer to Figure 3 and Figure 4 The moving component 43 includes a pushing block 431 slidably mounted inside the mounting seat 41 from left to right. One side of the pushing block 431 close to the center of the mounting seat 41 is fixedly connected with the corresponding wedge block 42. A return spring 432 is fixedly connected between the side of the pushing block 431 away from the center of the mounting seat 41 and the inner wall of the mounting seat 41.

[0042] Please refer to Figure 3 、 Figure 4 andFigure 8 Specifically, when in use, when the plug 52 is inserted into the jack 411, the plug 52 first contacts the inclined surface of the first wedge block 42, and then pushes the first wedge block 42 to move away from the center of the first mounting base 41. At this time, the first return spring 432 is compressed and contracted, so that the first wedge block 42 is completely retracted into the first mounting base 41 to avoid affecting the insertion and installation of the plug 52; when the plug 52 is completely inserted into the jack 411, the limiting groove 521 is just aligned with the first wedge block 42. At this time, the pushing block 431 and the first wedge block 42 are pushed to move towards the center of the first mounting base 41 by the resilience of the first return spring 432, so that the first wedge block 42 is inserted into the corresponding limiting groove 521 to lock the plug 52 and improve the firmness of the connection between the plug 52 and the first mounting base 41.

[0043] Please refer to Figure 3 and Figure 5 Please refer to

[0044] Please refer to Figure 3 、 Figure 5 and Figure 8 Specifically, when in use, when the vertical section of the second connector 32 is inserted into the terminal, the vertical section of the second connector 32 first contacts the inclined surface of the second wedge block 45, and the vertical section of the second connector 32 is used to push the second wedge block 45 to slide away from the center of the second mounting base 44 to avoid affecting the insertion of the second connector 32. At this time, the second return spring 462 is compressed and contracted. When the vertical section of the second connector 32 is completely inserted into the corresponding terminal, the pushing block 461 and the second wedge block 45 are pushed to move towards the center of the second mounting base 44 by the resilience of the second return spring 462, so that the second wedge block 45 locks the first connector 22 and the second connector 32 together to prevent the first connector 22 and the second connector 32 from loosening; at the same time, the pushing block 461 can also extrude the outer wall of the terminal to make the terminal fit more closely with the vertical section of the second connector 32, further avoiding the situation of poor contact.

[0045] Please refer to Figures 3-5, inside the first mounting seat 41 and the second mounting seat 44, there are also respectively installed a first unlocking component 47 and a second unlocking component 48 for unlocking the first wedge block 42 and the second wedge block 45. The first unlocking component 47 includes movable rods 471 that are slidably installed up and down inside the first mounting seat 41 and are symmetrically distributed left and right. The movable rods 471 are in an inverted L shape. There is a space reserved on the first mounting seat 41 for the up and down movement of the movable rods 471. A wedge-shaped groove 472 is formed on the first pushing block 431 for the up and down movement of the movable rods 471 to pass through. On the side of the vertical section of the movable rod 471 away from the center of the first mounting seat 41, a wedge-shaped insertion block 473 is fixedly connected. The wedge-shaped insertion block 473 is slidably inserted and matched with the inclined surface of the corresponding wedge-shaped groove 472. A third return spring 474 is fixedly connected between the bottom of the horizontal section of the movable rod 471 and the inner wall of the first mounting seat 41. The second unlocking component 48 has the same structure as the first unlocking component 47 and the movable rods 471 of the two are fixedly connected.

[0046] Please refer to Figures 3-5 , during specific use, when unlocking is required, push the movable rod 471 in the first unlocking component 47 downward. At this time, the third return spring 474 is compressed and contracted. The movable rod 471 drives the wedge-shaped insertion block 473 to move downward. By using the mutual cooperation between the wedge-shaped groove 472 and the wedge-shaped insertion block 473, the wedge-shaped insertion block 473 pushes the first pushing block 431 to move away from the center of the first mounting seat 41. The first pushing block 431 drives the first wedge block 42 to move away from the center of the first mounting seat 41, unlocking the locking of the first wedge block 42 on the plug 52. Similarly, when the upper movable rod 471 moves downward, the lower movable rod 471 will move downward synchronously, unlocking the locking of the second wedge block 45 on the first connector 22, and being able to quickly unlock the locking of the plug 52 and the second connector 32, facilitating the quick disassembly of the sleeve 3.

[0047] When the plugging mechanism 5 is completely separated from the connecting mechanism 4, release the downward pressure on the first unlocking component 47. Use the resilience of the third return spring 474 to push the movable rod 471 upward. Then the movable rod 471 drives the wedge-shaped insertion block 473 to move upward and reset. When the wedge-shaped insertion block 473 moves upward, the wedge-shaped insertion block 473 gradually releases the pushing on the first pushing block 431. At this time, use the resilience of the first return spring 432 to push the first pushing block 431 and the first wedge block 42 to move toward the center of the first mounting seat 41, resetting the first pushing block 431 and the first wedge block 42. Similarly, after the second unlocking component 48 releases the pushing on the second pushing block 461, the second pushing block 461 and the second wedge block 45 will be reset under the push of the second return spring 462, facilitating the subsequent installation of the sleeve 3.

[0048] Please refer to Figure 3 , Figure 4 and Figure 6, further comprising a linkage component 49. The linkage component 49 includes a sealing partition plate 491 slidably mounted up and down inside the first mounting base 41. The sealing partition plate 491 is annular. The horizontal section of the movable rod 471 in the first unlocking component 47 is fixedly connected to the inner wall of the sealing partition plate 491. Symmetrically distributed pushing blocks 492 are fixedly connected to the outer ring wall of the sealing partition plate 491. The pushing blocks 492 are slidably connected to the first mounting base 41 up and down, and the end away from the center of the first mounting base 41 extends to the outside of the first mounting base 41.

[0049] Please refer to Figure 3 , Figure 4 and Figure 6 . During specific use, the left and right movable rods 471 are connected together by the sealing partition plate 491. By pushing the pushing block 492 to drive the sealing partition plate 491 to move downward, the left and right movable rods 471 can be driven to move downward simultaneously, which is beneficial to the synchronous unlocking of the first wedge blocks 42 and the second wedge blocks 45 on both sides, facilitating the quick unlocking of the plug 52 and the second connector 32. At the same time, the sealing partition plate 491 can also seal the space reserved on the first mounting base 41 for the up and down movement of the movable rod 471, preventing external impurities from entering through the reserved space and avoiding adverse effects on the up and down movement of the movable rod 471.

[0050] Please refer to Figure 3 , Figure 8 and Figure 9 . A rotating shaft 531 is rotatably mounted at the hinge point of the clamping plate 53. The rotating shaft 531 is fixedly connected to the top of the gland 51. A torsion spring 532 for pushing the clamping plate 53 to rotate downward is fixedly installed on the rotating shaft 531. Windows 511 for the pushing blocks 492 to expose are opened on both the left and right sides of the gland 51. A blocking strip 533 for blocking and limiting the pushing blocks 492 is also fixedly connected to the side of the clamping plate 53 close to the center of the gland 51. The blocking strip 533 is located below the pushing blocks 492.

[0051] Please refer to Figure 3 , Figure 4 , Figure 8 and Figure 9 . During specific use, after the gland 51 is installed on the first mounting base 41, the torsion spring 532 is used to give the clamping plate 53 a downward rotation thrust, so that the clamping plate 53 can be clamped with the clamping block 412 to prevent the clamping plate 53 from becoming loose. After the clamping plate 53 is clamped with the clamping block 412, the clamping plate 53 blocks the outside of the window 511, and the pushing blocks 492 are blocked by the clamping plate 53 to prevent the pushing blocks 492 from being accidentally touched and moving downward, improving the safety of locking the plug 52 and the second connector 32. At the same time, the blocking strip 533 can support the pushing blocks 492 to prevent the pushing blocks 492 from moving up and down due to factors such as vibration and shaking, further improving the safety of locking the plug 52 and the second connector 32.
