Description

Technical Field

[0001] This utility model relates to the field of transformer frame technology, specifically a transformer frame adjustment device. Background Technology

[0002] The transformer bobbin, also known as the transformer wire frame, is the main structural component of a transformer and an indispensable part of it. In the current technology, for non-hollow type bobbins, when it is necessary to increase the number of winding turns, the fixed length of the non-hollow type bobbin may lead to insufficient winding area, forcing the winding to be more compact. It is impossible to adjust the length of the non-hollow type bobbin, which increases mold costs and inventory management difficulty.

[0003] For example, the authorized patent document with application number CN202221250438.1 discloses a transformer frame, which includes a winding part, pins and a first partition. The winding part is provided with an iron core hole that penetrates the winding part in the vertical direction. The winding part is used to wind the wire into a winding. The pins are connected to the lower end of the winding part and are used to wind the lead wire of the winding. There are two first partitions, which are respectively connected to the left and right sides of the winding part. The first partitions extend downward and the pins are located between the two first partitions.

[0004] The aforementioned patent has the problem that when it is necessary to increase the number of winding turns, the fixed-length non-hollow type frame may result in insufficient winding area and the length of the transformer frame cannot be adjusted. Therefore, we need to provide a transformer frame adjustment device. Utility Model Content

[0005] The purpose of this utility model is to provide a transformer bobbin adjustment device. By setting a position adjustment mechanism, the length of the transformer bobbin can be adjusted. Depending on the actual use scenario, increasing the bobbin length can accommodate more turns, while shortening the length reduces the number of turns. It can adapt to various electrical parameters without replacing the bobbin. The same bobbin can be compatible with winding designs of different wire diameters or layers, reducing inventory and production costs, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transformer frame adjustment device, comprising:

The two transmission mechanisms are respectively installed on both sides of the surface of the double threaded rod.

[0009] Preferably, the transmission mechanism includes a drive ring, a push rod, and a sliding member. The two drive rings are located on both sides of the surface of the double-threaded rod. The push rod is hinged to both sides of the drive ring. The end of the push rod away from the drive ring is used to press the contact plate against the inner wall of the middle frame. The middle frame is provided with a sliding member to prevent the push rod from falling off.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a transformer frame adjustment device, comprising:

[0026] The middle frame 1, the sleeve frame 2, and the position adjustment mechanism 3 are provided. The two sleeve frames 2 are respectively fitted on both sides of the surface of the middle frame 1. The position adjustment mechanism 3 is installed inside the middle frame 1 to limit the contact between the two sleeve frames 2.

[0027] Specifically, two sleeve frames 2 are slidably installed on the surface of the middle frame 1, and a position adjustment mechanism 3 is set inside the middle frame 1. The position adjustment mechanism 3 can limit and fix the middle frame 1, thereby changing the length of the transformer skeleton. The transformer skeleton is non-hollow. Increasing the length of the skeleton can accommodate more turns, while shortening the length reduces the number of turns.

[0028] The position adjustment mechanism 3 includes a contact plate 31, a double threaded rod 32 and a transmission mechanism 33. The two transmission mechanisms 33 are located inside the middle frame 1. The surface of the transmission mechanism 33 is provided with two contact plates 31. The transmission mechanism 33 is used to push the contact plates 31 to squeeze the sleeve frame 2. The two transmission mechanisms 33 are respectively installed on both sides of the surface of the double threaded rod 32.

[0029] Furthermore, the double threaded rod 32 is rotatably installed inside the intermediate frame 1. Both sides of the surface of the double threaded rod 32 are provided with transmission mechanisms 33. The two transmission mechanisms 33 are located in the two sleeve frames 2 respectively. The surface of the transmission mechanism 33 is provided with two abutment plates 31. By rotating the double threaded rod 32, the two abutment plates 31 can be controlled to move closer or further away from each other. When the two abutment plates 31 move closer to each other, they do not abut against the sleeve frame 2. The sleeve frame 2 can slide on the intermediate frame 1. After adjusting to a suitable position, the double threaded rod 32 is rotated in the opposite direction to move the two abutment plates 31 further away from each other, so that they fit against the inner wall of the sleeve frame 2 and are squeezed, thereby limiting and fixing the sleeve frame 2, and thus controlling the length adjustment of the transformer frame.

[0030] The transmission mechanism 33 includes a drive ring 331, a push rod 332 and a sliding member 300. The two drive rings 331 are located on both sides of the surface of the double threaded rod 32. The push rod 332 is hinged to both sides of the drive ring 331. The end of the push rod 332 away from the drive ring 331 is used to press the contact plate 31 to fit against the inner wall of the middle frame 1. The middle frame 1 is provided with a sliding member 300 to prevent the push rod 332 from falling off.

[0031] It is worth noting that a transmission mechanism 33 is provided with a drive ring 331 on one side. Two drive rings 331 are respectively threaded on both sides of the surface of the double threaded rod 32. The rotation of the double threaded rod 32 will drive the drive rings 331 to move, controlling the two drive rings 331 to move closer or further apart. When the two drive rings 331 move closer, the two push rods 332 on the surface of the drive rings 331 swing. The push rods 332 do not abut against the contact plate 31, which can realize the movement of the sleeve frame 2. When the two drive rings 331 move further apart, the drive rings 331 push the push rods 332 to swing, causing one end of the push rods 332 to press against the contact plate 31, causing the contact plate 31 to press against the sleeve frame 2, thus restricting the movement of the sleeve frame 2.

[0032] The sliding component 300 includes a reserved groove 301, a movable groove 302, and a support frame 303. The reserved groove 301 for the movement of the push rod 332 is provided in the middle frame 1, and the movable groove 302 for the movement of the support frame 303 is provided in the push rod 332. The support frame 303 is fixedly installed on the inner wall of the middle frame 1.

[0033] It is worth noting that the middle frame 1 is provided with a reserved slot 301 for adjusting the swing of the push rod 332, and the push rod 332 is provided with a movable slot 302, so that the support frame 303 can move within the movable slot 302, thus preventing the push rod 332 from getting stuck.

[0034] The surface of the contact plate 31 is provided with a toothed part 4 on the side away from the push rod 332, and the inner walls of the middle frame 1 are provided with toothed groups 5 on both sides that mesh with the toothed part 4;

[0035] Among them, the toothed part 4 on the surface of the contact plate 31 meshes with the toothed group 5 on the inner wall of the middle frame 1. When the toothed part 4 of the contact plate 31 meshes with the toothed group 5, it plays a limiting role on the sleeve frame 2, making the fixation more secure.

[0036] Four guide rods 6 are provided on one side of the contact plate 31, and all four guide rods 6 are slidably installed inside the middle frame 1;

[0037] Specifically, the movement of the contact plate 31 will cause the four guide rods 6 to slide within the middle frame 1, which will guide the movement of the contact plate 31 and make the movement of the contact plate 31 horizontal. In order to smoothly engage the toothed part 4 on the surface of the contact plate 31 with the toothed group 5, a spring part is sleeved on the surface of the guide rod 6. One end of the spring part is located on the inner wall of the middle frame 1, and the other end is located at the protrusion at the end of the guide rod. The spring part is set on the surface of the guide rod 6. When the push rod 332 does not press the contact plate 31, the spring part will bring the contact plate 31 close to the double threaded rod 32, so as to prevent the contact plate 31 from blocking the movement of the frame 2.

[0038] A support frame 7 is fixedly installed at the center of the surface of the middle frame 1, and the surface of the support frame 7 is slidably installed inside the two sleeve frames 2.

[0039] Furthermore, the surface of the support frame 7 is slidably installed inside the two sleeve frames 2 to fill the gaps between the two sleeve frames 2.

[0040] Several grooves 8 are provided on the opposite side of the two sleeve frames 2, and several pins 9 are provided at the bottom of the sleeve frames 2;

[0041] The trough 8 divides the winding into multiple blocks to prevent the wires of different layers or different windings from overlapping or crossing, reducing the risk of short circuits, ensuring neat winding, facilitating the operation of automated winding machines, and improving production efficiency and consistency. After the pin 9 is inserted into the PCB, it is fixed by solder or clips to prevent the transformer from shifting due to vibration or external force.

[0042] The double threaded rod 32 extends out of the middle frame 1 and is provided with an adjustment knob 10. The inner wall of the sleeve 2 is provided with guide strips 11 on all four sides. The adjacent side of the four guide strips 11 is in contact with the surface of the hollow frame.

[0043] The adjustment knob 10 is provided to facilitate the rotation adjustment of the double threaded rod 32. The inner wall of the sleeve 2 is provided with guide strips 11 on all four sides. The adjacent side of the four guide strips 11 is in contact with the surface of the hollow frame, so that the sleeve 2 slides horizontally in the middle frame 1 and avoids the sleeve 2 floating vertically in the middle frame 1.

[0044] When the length of the transformer frame needs to be adjusted, the double threaded rod 32 can be rotated to control the two contact plates 31 to move closer or further apart. When the two contact plates 31 move closer together, they do not contact the sleeve frame 2, and the sleeve frame 2 can slide on the middle frame 1. After adjusting to the appropriate position, the double threaded rod 32 is rotated in the opposite direction to move the two contact plates 31 further apart, so that they fit against the inner wall of the sleeve frame 2 and are squeezed, thereby limiting and fixing the sleeve frame 2, and thus controlling the length adjustment of the transformer frame.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
