Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a novel terminal block for transformers. Background Technology

[0002] In the field of transformer operation and wiring, the terminal block is the core component for achieving a stable connection between the transformer winding and the external conductor. Its connection stability, contact reliability and installation adaptability directly affect the power transmission efficiency and safe operation of the transformer. Therefore, there are strict requirements for the structural design and functional performance of the transformer terminal block.

[0003] Existing transformer terminals have significant drawbacks in practical use: First, most terminals use a straight-line clamping method to fix the wire core, which keeps the wire core in a straight line after clamping, resulting in a small contact area between the wire core and the conductive plate. The connection stability of the straight wire core is poor. Second, the conductive structure angle of the terminals is mostly fixed and cannot be flexibly adjusted according to the actual orientation of the wire core on site. Therefore, we have proposed a new type of transformer terminal. Utility Model Content

Four fixing holes are provided on the inner wall of the conductive arc plate. Fixing bolts are provided in each of the four fixing holes.

A threaded limiting hole is opened on the top of each of the two extrusion plates. An extrusion bolt is threadedly installed in each of the two threaded limiting holes. A moving mechanism is mounted on the back of the wiring conductive plate, which is used to cause the two extruded cylinders to move in opposite directions.

[0006] Preferably, the locking mechanism includes two side plates fixedly installed on the side of the conductive notch ring. Two locking holes are provided on the side of the two side plates that are close to each other. Two locking bolts are provided on one side of the conductive notch ring.

[0008] Preferably, the clamping plate has an arc-shaped groove on the side near the wiring conductive plate.

[0009] Preferably, the moving mechanism includes two connecting seats fixedly installed on the back of the wiring conductive plate. The two connecting seats have rotating holes on their adjacent sides. A circular sleeve is rotatably installed in the two rotating holes. The inner wall of the circular sleeve has two oppositely arranged second internal threads. A movable stud is threaded onto each of the two second internal threads. An L-shaped rod is fixedly installed at the opposite end of each of the two movable studs. A slider is fixedly installed on the top of each of the two L-shaped rods.

The moving stud with the reverse thread drives the two extrusion cylinders to move closer to each other, extruding the wire core and bending it. This increases the contact area between the wire core and the conductive plate, and enhances the stability of the connection structure through the bending shape of the wire core.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows: A new type of transformer terminal block includes a conductive notch ring 2, on the inner wall of which a first internal thread 9 is provided, and a locking mechanism is installed on the side of the conductive notch ring 2. A conductive arc plate 3 is provided on one side of the conductive notch ring 2. Four fixing holes are provided on the inner wall of the conductive arc plate 3. Each of the four fixing holes is provided with a fixing bolt 4. Each fixing bolt 4 has multiple threaded fixing grooves 8 on one side of the outer side of the conductive notch ring 2. The fixing bolt 4 is threaded into the corresponding threaded fixing groove 8. According to the orientation of the wire core, the angle between the conductive arc plate 3 and the conductive notch ring 2 is adjusted. Then, by rotating the four fixing bolts 4, they are respectively inserted into the four corresponding threaded fixing grooves 8, thus completing the fixing of the conductive arc plate 3 and the conductive notch ring 2.

[0019] A wiring conductive plate 1 is fixedly installed on one side of the conductive arc plate 3, and two clamping mechanisms are installed on the top of the wiring conductive plate 1. Two extrusion cylinders 12 are arranged between the two clamping mechanisms. Extrusion plates 11 are fixedly installed on the top of each of the two extrusion cylinders 12. Threaded limiting holes are opened on the top of each of the two extrusion plates 11. Extrusion bolts 10 are threadedly installed in each of the two threaded limiting holes. A moving mechanism is installed on the back of the wiring conductive plate 1, which is used to make the two extruded cylinders 12 move in opposite directions.

[0020] like Figure 1 As shown, the locking mechanism includes two side plates 6 fixedly installed on the side of the conductive notched ring 2. Each side plate 6 has two locking holes on its adjacent sides. Two locking bolts 7 are provided on one side of the conductive notched ring 2. One end of each locking bolt 7 passes through the two locking holes and is threaded with a locking nut 5. The locking nuts 5 and locking bolts 7 allow the notches of the conductive notched ring 2 to be connected.

[0021] like Figure 2 As shown, the clamping mechanism includes two clamping studs 13 fixedly installed on the side of the conductive plate 1. A clamping plate 15 is slidably sleeved on the two clamping studs 13, and a clamping nut 14 is threaded onto each of the two clamping studs 13, with the clamping nut 14 located above the clamping plate 15. Rotating the two clamping nuts 14 will move the clamping plate 15, thereby clamping the wire core. like Figure 2 The clamping plate 15 has an arc-shaped groove on its side near the wiring conductive plate 1. The arc-shaped groove facilitates the clamping of the wire core.

[0022] like Figure 3 and Figure 4As shown, the moving mechanism includes two connecting seats 19 fixedly mounted on the back of the conductive plate 1. Rotating holes are provided on the sides of the two connecting seats 19 that are close to each other. A circular sleeve 20 is rotatably mounted in each of the two rotating holes. Two opposing second internal threads are provided on the inner wall of the circular sleeve 20. Moving studs 22 are threaded onto each of the two second internal threads. L-shaped rods 17 are fixedly mounted at the ends of the two moving studs 22 that are far apart from each other. Slider blocks 18 are fixedly mounted on the tops of the two L-shaped rods 17. The two sliders 18 are respectively connected to the bottoms of the two extrusion cylinders 12. Rotating the circular sleeve 20 causes the moving studs 22 to move closer together due to the opposite thread directions. The movement of the two moving studs 22 moves the two L-shaped rods 17 and the two sliders 18 closer together, thereby bringing the two extrusion cylinders 12 closer together. The movement of the two extrusion cylinders 12 extrudes the wire core, causing the wire core between the lower clamping stud 13 and the guide frame 23 to bend, thereby increasing the contact area between the wire core and the conductive plate 1.

[0023] like Figure 4 As shown, a hexagonal post 21 is fixedly fitted onto the circular sleeve 20, and the two sides of the hexagonal post 21 respectively contact the adjacent sides of the two connecting seats 19. The hexagonal post 21 facilitates the rotation of the circular sleeve 20 by the wrench.

[0024] like Figure 2 As shown, the top of the conductive plate 1 has two sliding holes 16, and two sliders 18 are slidably installed in the two sliding holes 16 respectively. The sliding holes 16 are designed to limit the sliders 18 so that they can only slide.

[0025] like Figure 2 As shown, a guide frame 23 is installed on the side of the conductive plate 1, and the guide frame 23 corresponds to the positions of the two clamping studs 13 located above. The guide frame 23 can guide the wire core and prevent the wire core from not corresponding to the position of the clamping plate 15 above after bending, which facilitates the subsequent fixing of the clamping plate 15 above.

[0026] Working principle: In use, the conductive notch ring 2 and the four fixing bolts 4 on the conductive arc plate 3 are removed. Then, the conductive notch ring 2 is threaded onto the connection end of the transformer through the first internal thread 9. After the wire core passes through the guide frame 23 and is located in the lower clamping plate 15, the bottom of the wire core can be clamped by rotating the two clamping nuts 14 below. Then, by turning the hexagonal column 21 with a wrench, the sleeve 20 can be rotated. Since the threads of the moving studs 22 are opposite, the two moving studs 22 move closer to each other. The movement of the two moving studs 22 drives the two L-shaped rods 17 and the two sliders 18 to move closer to each other, thereby bringing the two extrusion cylinders 12 closer to each other. The movement of the two extrusion cylinders 12 extrudes the wire core, causing the wire core between the lower clamping stud 13 and the guide frame 23 to bend, thereby increasing the contact area between the wire core and the wiring conductive plate 1. After bending is completed, the wire core is pressed by rotating the extrusion bolt 10 to improve the connection stability of the wire core. Finally, the top of the wire core is pressed by rotating the two upper clamping nuts 14. Then, adjust the angle between the conductive arc plate 3 and the conductive notch ring 2 according to the orientation of the wire core. Then, rotate the four fixing bolts 4 to make them enter the corresponding four threaded fixing grooves 8 respectively, thus completing the fixing of the conductive arc plate 3 and the conductive notch ring 2.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
