Description

Technical Field

[0001] This invention relates to transformer technology, and more particularly to a transformer frame structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core. In electrical equipment and wireless circuits, it is commonly used for voltage step-up / step-down, impedance matching, and safety isolation. In generators, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil, an electromotive force is induced in the coil.

[0003] In practical applications, transformers typically require cable securing during installation to ensure cable stability. Current technology usually employs bolts and other fixing components, which necessitates specialized tools. This not only compromises the safety of workers at certain heights but also increases the time workers spend suspended in the air.

[0004] CN212136139U discloses an easy-to-connect oil-immersed transformer. By rotating a throttle clockwise, the throttle rotates the pressure pins. The threaded structure on the outside of the pressure pins interacts with the internal thread on the top of the terminal block, pushing the pressure pins downwards. While this method can secure the wires, the threaded structure can rust over time, and the smooth surface between the pressure pins and the terminals makes them prone to loosening, leading to unstable current delivery. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention proposes a transformer frame structure.

[0006] A transformer frame structure, characterized in that it comprises:

[0007] A transformer body, wherein heat sinks are provided on the outside of the transformer body;

[0008] Multiple conductive terminals are provided at the upper end of the transformer body. Each conductive terminal is equipped with a conductive component, which consists of a conductive element, an insulating element, a movable element, a tension spring, and a cable. The conductive element is installed on the conductive terminal. One end of the movable element is hinged to the conductive element via a first hinge rod. The insulating element is located between the conductive element and the movable element. One end of the tension spring is kept connected to the insulating element, and the other end is kept hinged to the first hinge rod.

[0009] The conductive component consists of a fixing part and a conductive plate. The fixing part has an opening groove, and fixing ears are provided on both sides of the opening groove. A fixing hole for cooperating with a conductive terminal is formed in the middle of the fixing part. The conductive plate has symmetrically arranged fixing blocks and symmetrically arranged positioning blocks. An installation area is formed between the fixing blocks and the moving part is disposed in the installation area. The first hinge rod is disposed on the fixing block. A second hinge rod is provided between the positioning blocks and the positioning block. A sliding gap is formed between the second hinge rod and the conductive plate to accommodate the moving part.

[0010] The fixed block is provided with a fixed protrusion, and a fixed opening is formed in the middle of the fixed protrusion. The movable part is provided with an arc-shaped concave surface, and an arc-shaped opening that matches the fixed opening is formed between the arc-shaped concave surfaces.

[0011] The cable is provided with a retaining member that mates with the fixed opening and the arc-shaped opening. The retaining member pushes the movable member to restrict the retaining member within the fixed opening and the arc-shaped opening.

[0012] In this invention, the conductive plate is provided with a first strip hole, which is located in the mounting area between the fixing block and the fixing block.

[0013] In this invention, the insulating component consists of a sliding plate, an arc-shaped plate, and a pulling part, wherein the sliding plate is located within the mounting area and the sliding gap.

[0014] In this invention, the sliding plate is provided with a second strip-shaped hole, which is configured to cooperate with the first strip-shaped hole.

[0015] In this invention, the sliding plate is provided with a limiting block, and the limiting block is provided with a pulling rod that cooperates with the tension spring in the middle.

[0017] In this invention, a movable gap is formed between the movable component and the insulating component.

[0018] In this invention, the movable component is provided with a guide slope and a first sliding surface.

[0019] In this invention, the cable is composed of a conductor and an insulation layer. The retainer is fixed on the conductor. The retainer is composed of a sleeve and retaining ends disposed at both ends of the sleeve. A retaining hole that mates with the conductor is formed in the middle of the sleeve. The outer diameter of the retaining end is larger than the outer diameter of the sleeve. A retaining area for accommodating a fixed block and a movable part is formed between the retaining end and the retaining end.

[0020] The transformer frame structure of this invention has the following advantages: By setting a retaining member on the cable, the retaining member cooperates with the conductive and moving parts.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] like Figures 1 to 15 As shown, this transformer frame structure of the present invention includes a transformer body 1 and a conductive component 2. The conductive component 2 is used to draw out the high-voltage current converted inside the transformer body 1, so that the low-voltage current is drawn out from the cable 3 on the conductive component 2. By providing a retaining member 4 on the cable 3, the retaining member 4 cooperates with the conductive component 5 and the movable component 6 to achieve electrical connection. At the same time, the movable component 6 restricts the position of the retaining member 4 on the cable 3, thereby realizing tool-less installation and tool-less removal of the cable 3, which facilitates workers to quickly install or remove the cable 3.

[0039] Even if the high-voltage line switch is disconnected when the transformer is in use, some current will still exist inside the transformer. This can affect the normal operation of the workers during installation and may cause electrical safety accidents.

[0040] The transformer body 1 is equipped with heat sinks 7 on its exterior for heat dissipation. A mounting base 8 is located at the lower end of the transformer body 1 to facilitate its installation onto a support frame. The transformer body 1 also includes other structures that contribute to the normal operation of the transformer; however, as these are existing technologies, they will not be described in detail here.

[0041] Multiple conductive terminals 9 are provided at the upper end of the transformer body 1. Each conductive terminal 9 is equipped with a conductive component 2, which consists of a conductive element 5, an insulating element 10, a movable element 6, a tension spring 11, and a cable 3. The conductive element 5 is fixed to the conductive terminal 9, the movable element 6 is hinged to the conductive element 5, and the insulating element 10 is positioned between the movable element 6 and the conductive element 5, and can slide a certain distance between them. The tension spring 11 is used to pull the insulating element 10 closer to the movable element 6, so that after pulling the insulating element 10, the elastic force of the tension spring 11 keeps the insulating element 10 close to the movable element 6, thus restoring it to its original position.

[0042] The conductive element 5 is mounted on the conductive terminal 9. One end of the movable element 6 is hinged to the conductive element 5 via the first hinge rod 12. The insulating element 10 is disposed between the conductive element 5 and the movable element 6. One end of the tension spring 11 is kept connected to the insulating element 10, and the other end is kept hinged to the first hinge rod 12. Since the conductive element 5 remains stationary, one end of the tension spring 11 is restricted to remain stationary, i.e., the movable element 6 also remains stationary. Therefore, when the insulating element 10 moves, it can keep the insulating element 10 pulling the tension spring 11, thereby stretching the tension spring 11 and generating elastic force. When the external force pulling the insulating element 10 disappears, the insulating element 10 can be reset under the elastic force generated by the tension spring 11.

[0043] The conductive component 5 consists of a fixing part 13 and a conductive plate 14. The fixing part 13 has an opening groove 15, and fixing ears 16 are provided on both sides of the opening groove 15. A fixing hole 17 is formed in the middle of the fixing part 13 to mate with the conductive terminal 9. When the two fixing ears 16 are brought close to each other by bolts, the distance of the opening groove 15 on the fixing part 13 can be reduced, thereby fixing the conductive component 5 to the conductive terminal 9.

[0044] The conductive plate 14 is provided with symmetrically arranged fixing blocks 18 and symmetrically arranged positioning blocks 19. An installation area 20 is formed between the fixing blocks 18 and the positioning blocks 19. The movable member 6 is disposed in the installation area 20. A first hinge rod 12 is disposed on the fixing block 18, and the fixing block 18 is provided with a hinge hole 21 that mates with the first hinge rod 12. A second hinge rod 22 is provided between the positioning blocks 19 and the positioning blocks 19. A sliding gap 23 is formed between the second hinge rod 22 and the conductive plate 14 to accommodate the movable member 6. The sliding gap 23 is used to limit the position of the insulating member 10 so that it can slide easily.

[0045] The fixing block 18 has a fixing protrusion 24, with a fixing opening 25 in the middle of the fixing protrusion 24. The movable part 6 has an arc-shaped concave surface 26, and an arc-shaped opening 27 that mates with the fixing opening 25 is formed between the arc-shaped concave surfaces 26. The fixing opening 25 and the arc-shaped opening 27 mate to confine the retaining part 4 within them, so that the sleeve 28 is placed within the fixing opening 25 and the arc-shaped opening 27, thereby confining the cable 3 and achieving electrical connection.

[0046] The cable 3 is provided with a retaining member 4 that cooperates with the fixed opening 25 and the arc-shaped opening 27. The retaining member 4 pushes the movable member 6 to restrict the retaining member 4 within the fixed opening 25 and the arc-shaped opening 27.

[0047] Cable 3 consists of a conductor 29 and an insulation layer 30. A retainer 4 is fixed to the conductor 29 and consists of a sleeve 28 and retaining ends 31 at both ends of the sleeve 28. A retaining hole 32 is formed in the middle of the sleeve 28 to mate with the conductor 29. The outer diameter of the retaining end 31 is larger than the outer diameter of the sleeve 28. A retaining area 33 is formed between the retaining ends 31 to accommodate the fixed block 18 and the movable part 6. Because the retainer 4 is fixed to the conductor 29, a strong frictional force is generated between the retainer 4 and the conductor 29, simultaneously achieving electrical connection.

[0048] By providing retaining ends 31 at both ends of the sleeve 28, the position of the retaining member 4 can be effectively restricted, preventing it from moving out of both ends of the fixed block 18. This, in conjunction with the movable member 6, can achieve positional restriction in the up-down, left-right, front-back, and rear directions.

[0049] The conductive plate 14 is provided with a first strip-shaped hole 34, which is located in the mounting area 20 between the fixing block 18 and the fixing block 18. The first strip-shaped hole 34 is used to cooperate with the second strip-shaped hole 35 to restrict the position of the movable column 36. After the insulating member 10 is pulled upward, the movable column 36 can be driven to rotate around the first hinge rod 12 through the second strip-shaped hole 35 on the insulating member 10. This allows the movable column 36 to rotate upward within the first strip-shaped hole 34, thereby causing the arc-shaped opening 27 to rotate downward. As a result, the movable member 6 no longer restricts the retaining member 4, allowing the opening of the fixing opening 25 to open, and the retaining member 4 can be removed from the fixing opening 25.

[0050] The insulating component 10 consists of a sliding plate 37, an arc-shaped plate 38, and a pulling part 39. The sliding plate 37 is located within the mounting area 20 and the sliding gap 23. A second strip-shaped hole 35 is provided on the sliding plate 37, which is configured to cooperate with the first strip-shaped hole 34.

[0051] like Figure 13As shown, the movable column 36 is currently positioned within the first slot 34 and the second slot 35. The lower end of the first slot 34 contacts the movable column 36, while the upper end of the second slot 35 contacts the movable column 36. Since the first slot 34 remains stationary, and the second slot 35 is located on the insulating member 10, the tension of the spring 11 can cause the insulating member 10 to exert tension on the movable column 36. The movable column 36 is then pressed by the second slot 35, causing it to place pressure within the first slot 34, thus maintaining the position of the movable member 6 and blocking the retaining member 4. However, if the retaining member 4 slides from the guide ramp 40 on the movable member 6 and enters the fixed opening 25, the retaining member 4 can push the movable member 6, allowing the movable column 36 on the movable member 6 to rotate around the first hinge rod 12. The movable column 36 then pushes the insulating member 10 upwards, stretching the spring 11, and causing the movable column 36 to rotate upwards within the first slot 34.

[0052] A limiting block 41 is provided on the sliding plate 37, and a pulling rod 42 that cooperates with the tension spring 11 is provided in the middle of the limiting block 41. Through the cooperation of the limiting block 41 and the pulling rod 42, the insulating member 10 can be pulled by the tension spring 11.

[0053] A movable post 36 is provided on the movable part 6, which extends through the second strip hole 35 into the first strip hole 34. The movable post 36 is used to hold the position of the movable part 6, facilitating the installation of the retainer 4, while preventing the retainer 4 from being removed.

[0054] A movable gap 43 is formed between the movable part 6 and the insulating part 10. For example... Figure 13 As shown, the movable gap 43 is located between the movable part 6 and the insulating part 10, so that when the movable part 6 rotates, the movable part 6 can move closer to the insulating part 10, thereby facilitating the rotation of the arc-shaped opening 27 on the movable part 6 to the position corresponding to the fixed opening 25.

[0055] The movable part 6 is provided with a guide slope 40 and a first sliding surface 44, while the fixed block 18 is provided with a second sliding surface 45. The first sliding surface 44 is used to guide the retaining part 4 into the fixed opening 25, while the second sliding surface 45 guides the retaining part 4 into the guide slope 40 and then into the fixed opening 25.

[0056] like Figure 9As shown, the arc angle is 90°, and the first sliding surface 44 is exactly vertical and located in the middle of the fixed opening 25. When the retainer 4 enters the arc opening 27 and the fixed opening 25, its position is precisely restricted by the arc opening 27. When the retainer 4 needs to be removed, since the first sliding surface 44 is located in the middle of the fixed opening 25 and its position is on the same vertical plane as the center line of the retainer 4, the retainer 4 will not obstruct the rotation of the arc concave surface 26 when the movable part 6 rotates downward.

[0057] like Figure 14 As shown, the movable column 36 is precisely restricted by the pressure of the insulating member 10 at this time, and the tension spring 11 will pull the insulating member 10 to keep the insulating member 10 acting on the movable column 36.

[0058] like Figure 15 As shown, the movable column 36 is currently positioned within the first strip-shaped hole 34, at its lower end, and... Figure 14 The state is consistent, that is, the movable column 36 is pressed by the insulating member 10 at this time, thereby restricting the position of the movable member 6.

[0059] When the insulating member 10 is pulled, the upper end of the second strip hole 35 is first kept separate from the movable column 36, and then the lower end of the second strip hole 35 is brought into contact with the movable column 36. Then, the insulating member 10 pulls the movable column 36 to rotate around the first hinge rod 12, so that the movable column 36 rotates upward in the first strip hole 34.

[0060] When installing cable 3, the worker can push the retaining member 4 by directly pressing it, causing the retaining member 4 to push the movable member 6. The movable post 36 on the movable member 6 pushes the insulating member 10 upward, causing the tension spring 11 to be stretched. The movable member 6 rotates around the first hinge rod 12, thereby achieving the positional misalignment of the arc-shaped opening 27 and the fixed opening 25. The retaining member 4 can enter the fixed opening 25. After the retaining member 4 contacts the inner wall of the fixed opening 25, the movable member 6 is no longer under the pressure of the retaining member 4. Thus, when the tension spring 11 pulls the insulating member 10, the second strip hole 35 presses the movable post 36, causing the movable member 6 to reset. The arc-shaped concave surface 26 contacts the retaining member 4, thereby blocking the retaining member 4 and restricting its position.

[0061] When removing the retainer 4, the insulating part 10 can be pulled upwards first, causing the insulating part 10 to pull the tension spring 11. The tension spring 11 is stretched, and the insulating part 10 drives the second strip hole 35 to move upwards. When it continues to move upwards, it can drive the movable column 36 to rotate around the first hinge rod 12, so that the movable column 36 rotates upwards in the first strip hole 34, and the arc concave surface 26 disengages from the retainer 4. Thus, the movable part 6 no longer blocks the retainer 4, and the retainer 4 and cable 3 can be removed.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
