Description

Technical Field

[0001] This invention belongs to the field of transformer technology, specifically a transformer lead structure. Background Technology

[0002] Chinese patent CN218886966U discloses a transformer lead structure, including a transformer body. Low-voltage terminals are equidistantly installed on the top of the transformer body, and an L-shaped plate is fixed to the top of the transformer body. This utility model, by setting up a transformer body, low-voltage terminals, an L-shaped plate, a support base, a limiting plate, and a fixing component, allows for the limiting and fixing of the lead bodies on the transformer, making the lead bodies more stable after connection. The fixing component is connected to the limiting plate using a spring-loaded snap-fit ​​method, facilitating operation of the lead bodies. Each lead body is individually fixed, preventing disorder during use, ensuring the quality of transformer operation, and simplifying maintenance. However, this device has a drawback: the fixing component needs to be snapped onto the limiting plate to secure the lead. If the fixing component is lost before use or falls off during use, it causes inconvenience and reduces work efficiency. In addition, the lead wire needs to pass through the limiting collar and the L-shaped plate. This process requires pulling the entire lead wire out of the limiting collar and the L-shaped plate, which is inconvenient to use. Summary of the Invention

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0031] Example 1

[0032] Please see Figures 1-7 As shown, this application provides a transformer lead structure, including a transformer body 1, an L-shaped plate 2 fixedly connected to the top of the transformer body 1, a through groove 3 through the top of the L-shaped plate 2, and one side of the through groove 3 is open.

[0033] Mounting mechanism 4 is mounted on L-shaped plate 2, and the mounting mechanism 4 is used to fix lead wire 5;

[0034] A blocking mechanism 6 is installed on the L-shaped plate 2, and the blocking mechanism 6 is used to block the through groove 3.

[0035] The installation mechanism 4 includes a fixing frame 49 fixedly connected to the L-shaped plate 2. A connecting frame 41 is movably connected to the fixing frame 49. The connecting frame 41 has a certain weight. A first inclined plate 42 and a connecting plate 43 are fixedly connected to the fixing frame 49. A second inclined plate 45 that cooperates with the first inclined plate 42 is connected to the connecting frame 41 through a reset component 44. The second inclined plate 45 and the first inclined plate 42 have a magnetic attraction. An arc plate 46 is fixedly connected to the second inclined plate 45. There are two second inclined plates 45. A semi-cylinder 47 is fixedly connected to the connecting plate 43. A snap-fit ​​component 48 is provided between the connecting frame 41 and the fixing frame 49. The lead wire 5 is placed in the semi-cylinder 47. Then, the second protrusion 485 is lifted and rotated, thereby driving the first protrusion 484 to rotate through the connecting rod 483. The first protrusion 484 is then moved out of the slot 10. Afterward, it descends to the lowest point due to the weight of the connecting frame 41. During the descent, the second inclined plate 45 and the first inclined plate 42 come into contact with each other, so that the two arc plates 46 move closer to each other and fit together, forming a complete cylindrical structure with the semi-cylinder 47. The lead wire 5 is wrapped and clamped by the first clamping plate 15 and the second clamping plate 16 to achieve fixation, while the first spring 443 is under tension. Under the magnetic action between the second inclined plate 45 and the first inclined plate 42, the second inclined plate 45 and the first inclined plate 42 will not separate when vibration occurs. When it is necessary to disassemble the lead wire 5, firstly, open the two baffles 61 outwards, then move the lead wire 5 out of the through groove 3, and then move the entire mounting mechanism 4 upward by lifting the second protrusion 485 (while the arc panel 46 returns to its original position under the action of the first spring 443, so that the two arc panels 46 will open with each other). When the connecting frame 41 moves to the highest point, rotate the second protrusion 485, which will cause the first protrusion 484 to rotate. Then, move it downwards a certain distance so that the first protrusion 484 is stuck in the slot 10. Then, take the lead wire 5 out of the half-cylinder 47. Then, pull the lead wire 5 upwards, which will cause the lead wire 5 to be removed from the clamp 12, thereby realizing the disassembly of the lead wire 5.

[0036] The reset assembly 44 includes a movable plate 441 slidably connected to the connecting frame 41 and a fixed plate 442 fixedly connected to the connecting frame 41. A first spring 443 is fixedly connected between the movable plate 441 and the fixed plate 442. The first spring 443 is in a stretched state. The movable plate 441 is fixedly connected to the second inclined plate 45.

[0037] The front of the fixing frame 49 is provided with a first movable groove 7, and a second movable groove 8 connected to the first movable groove 7 is provided on one side of the fixing frame 49. A straight rod 9 is fixedly connected in the first movable groove 7.

[0038] The snap-fit ​​assembly 48 includes a folding plate 481 fixedly connected to the connecting frame 41 and a support block 482 fixedly connected to the fixing frame 49. A connecting rod 483 is rotatably connected to the folding plate 481. A protrusion 484 and a protrusion 485 are fixedly connected to the connecting rod 483 respectively. Two support blocks 482 are provided.

[0039] The folding plate 481 is slidably connected to the first movable groove 7, the second movable groove 8 and the straight rod 9 respectively. The front of the support block 482 is provided with a through groove 10, and the top of the groove 10 is open.

[0040] Vertical plates 14 are fixedly connected to both the front and back of the connecting frame 41. The first spring 443 is located between the two vertical plates 14. Fixed clamping plate 15 is fixedly connected to the arc panel 46. Fixed clamping plate 2 16 is fixedly connected to the semi-cylinder 47.

[0041] Example 2

[0042] Based on Example 1, see Figures 1-3 As shown.

[0043] An elastic plate 11 is fixedly connected to the top of the fixing frame 49. A clamp 12 is integrally formed on the elastic plate 11, and an inclined plate 13 is integrally formed on the clamp 12. The connection between the clamp 12 and the inclined plate 13 is arc-shaped. There are two elastic plates 11. The lead wire 5 is placed on the inclined plate 13. Then, the lead wire 5 is pressed, causing the elastic plate 11 to bend and deform to one side. Then, the clamp 12 and the inclined plate 13 tilt to one side as a whole. Then, the lead wire 5 will enter the clamp 12. After that, the elastic plate 11 will return to its original position when the pressure is released, so that the two clamps 12 will wrap around the outside of the lead wire 5.

[0044] Example 3

[0045] Based on Example 1, see Figure 1 , Figure 2 and Figure 7 As shown.

[0046] The shielding mechanism 6 includes a baffle 61 rotatably connected to the L-shaped plate 2. Two baffles 61 are provided, and the two baffles 61 are fitted together. A groove 62 is provided on the baffle 61. An inclined plate 63 is integrally formed on the baffle 61. The connection between the baffle 61 and the inclined plate 63 is provided as an arc surface. A reset component 64 is provided between the inclined plate 63 and the L-shaped plate 2. The lead wire 5 is attached to the inclined plate 63 and pressed down, causing the baffle 61 to rotate. This causes the second spring 643 to bend via the bent rod 641. Then, the lead wire 5 is moved along the gap between the two baffles 61 towards the groove 62 (i.e., the lead wire 5 moves in the through groove 3). When the lead wire 5 moves to the groove 62 (i.e., the lead wire 5 moves to the innermost part of the through groove 3), the second spring 643 causes the baffle 61 to return to its original position. This not only blocks the through groove 3 but also further fixes and limits the lead wire 5. Through the above operations, the lead wire 5 is thus fixed.

[0047] The reset assembly 64 includes a bent rod 641 fixedly connected to the inclined plate 63, and a connecting seat 642 fixedly connected to the L-shaped plate 2. A second spring 643 is fixedly connected between the bent rod 641 and the connecting seat 642.

[0048] Example 4

[0049] Referring to Embodiments 1, 2, and 3, see Figures 1-7 As shown.

[0050] By making the arc panel 46 and the fixing bracket 49 a whole, the problem of installation inconvenience caused by the loss or falling of existing fixing components is avoided. Before fixing the lead wire 5, the two arc panels 46 are separate from each other, which is conducive to placing the lead wire 5 in the semi-cylinder 47. During the fixing of the lead wire 5, the two arc panels 46 fit together and form a complete cylindrical structure with the semi-cylinder 47, thus fixing the lead wire 5.

[0051] The working principle of this invention is as follows: by placing the lead wire 5 on the inclined plate 13, and then pressing the lead wire 5, the elastic plate 11 is bent and deformed to one side. Then, the clamp 12 and the inclined plate 13 tilt to one side as a whole. Then, the lead wire 5 will enter the clamp 12. After that, the elastic plate 11 will return to its original position when the pressure is lost, so that the two clamps 12 will wrap around the outside of the lead wire 5.

[0052] Next, the lead wire 5 is placed in the semi-cylinder 47. Then, the second protrusion 485 is lifted and rotated, thereby driving the first protrusion 484 to rotate through the connecting rod 483. As a result, the first protrusion 484 moves out of the slot 10. Then, it descends to the lowest point due to the weight of the connecting frame 41. During the descent, the second inclined plate 45 and the first inclined plate 42 come into contact with each other, so that the two arc plates 46 come closer together and fit together, forming a complete cylindrical structure with the semi-cylinder 47. The lead wire 5 is wrapped and clamped by the first fixed clamp plate 15 and the second fixed clamp plate 16 to achieve fixation, while the first spring 443 is under tension. Under the magnetic action between the second inclined plate 45 and the first inclined plate 42, the second inclined plate 45 and the first inclined plate 42 will not separate when vibration occurs.

[0053] Next, the lead wire 5 is attached to the inclined plate 63 and pressed down, causing the baffle 61 to rotate. This causes the second spring 643 to bend via the bent rod 641. Then, the lead wire 5 is moved along the gap between the two baffles 61 towards the groove 62 (i.e., the lead wire 5 moves in the through groove 3). When the lead wire 5 moves to the groove 62 (i.e., the lead wire 5 moves to the innermost part of the through groove 3), the second spring 643 causes the baffle 61 to return to its original position. This not only blocks the through groove 3 but also further fixes and limits the lead wire 5. Through the above operations, the lead wire 5 is thus fixed.

[0054] When it is necessary to disassemble the lead wire 5, firstly, open the two baffles 61 outwards, then move the lead wire 5 out of the through groove 3, and then move the entire mounting mechanism 4 upward by lifting the second protrusion 485 (while the arc panel 46 returns to its original position under the action of the first spring 443, so that the two arc panels 46 will open with each other). When the connecting frame 41 moves to the highest point, rotate the second protrusion 485, which will cause the first protrusion 484 to rotate. Then, move it downwards a certain distance so that the first protrusion 484 is stuck in the slot 10. Then, take the lead wire 5 out of the half-cylinder 47. Then, pull the lead wire 5 upwards, which will cause the lead wire 5 to be removed from the clamp 12, thereby realizing the disassembly of the lead wire 5.

[0055] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
