The existing transformer structure is prone to collisions between the casing and circuit boards and components during disassembly and assembly, which affects the transformer performance and fails to meet the requirements for convenient and stable disassembly and assembly.
The structure employs positioning pins, support columns, and snap-fit blocks with different orientations. The cooperation between the snap-fit blocks and the snap-fit blocks ensures stable opening and closing of the upper and lower shells, preventing collisions between the shells and the circuit board. Elastic components are used to improve the pre-tightening effect of the snap-fit blocks.
This enables stable assembly and disassembly of transformers, avoiding collisions between the casing and circuit boards and components, thus improving operational efficiency and ease of assembly.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, specifically a transformer structure for preventing collisions. Background Technology
[0002] A transformer typically consists of a housing structure and internal components such as circuit boards. When assembling a transformer, in addition to ensuring the stable positioning of the circuit boards and other components, it's also necessary to consider whether the housing structure will collide with the circuit boards during assembly. That is, the assembly path must not overlap with the location of the circuit boards, and the two must not cause structural interference. However, existing transformer structures cannot meet the requirements for convenient and stable assembly and disassembly, resulting in collisions between the housing and the circuit boards and their components during assembly and disassembly, thus affecting transformer performance.

[0009] The second buckle is located on the upper shell, on the side of the first buckle, with its hook facing parallel to the side wall of the upper shell, and it engages with the second buckle block on the side wall of the lower shell.
[0010] As a further description of the above technical solution:
[0011] The inner wall of the lower shell is provided with a plurality of first support columns, and the inner wall of the upper shell is provided with a plurality of second support columns. The first support columns and the second support columns respectively abut against the two ends of the positioning holes on the circuit board.
[0012] As a further description of the above technical solution:
[0013] The two first locking blocks are spaced apart along the height direction of the inner wall of the upper shell, and the hooks of the first buckles abut against the opposite surfaces of the two first locking blocks.
[0014] As a further description of the above technical solution:
[0015] The two second locking blocks are spaced apart along the height direction of the inner wall of the lower shell, and the hooks of the second buckles abut against the opposite surfaces of the two second locking blocks.
[0016] As a further description of the above technical solution:
[0017] The inner wall of the lower shell is provided with an installation box, and the first buckle is vertically slidably connected in the movable groove of the installation box.
[0018] As a further description of the above technical solution:
[0019] An elastic element is provided between the first buckle and the movable groove.
[0020] In summary, by adopting the above technical solution, this utility model has the following advantages over the prior art:
[0021] Beneficial effects:
[0022] This utility model's transformer structure utilizes two differently oriented snap-fit blocks to achieve more stable opening and closing guidance for the upper and lower shells, preventing lateral displacement of the shells during assembly and disassembly that could lead to collisions with the internal circuit boards and components. During assembly, the circuit board is placed into the lower shell, the positioning pin is inserted into the through hole, and the first support column abuts against the positioning hole, completing the initial positioning of the circuit board. The lower and upper shells are aligned and pressed together, with the two snap-fit blocks initially engaging and guiding. Further pressing allows the second snap-fit block to slide along the surface of the mounting box, while the first snap-fit block slides along the inner wall of the upper shell until both snap-fit blocks engage with their corresponding blocks. At this point, the positioning pin abuts against the inner wall of the upper shell, and the second support column abuts against the positioning hole, completing the transformer structure assembly. This design facilitates personnel operation and improves work efficiency. Attached Figure Description

[0033] Please see Figure 1-5 This utility model provides a technical solution: a transformer structure to prevent collisions, comprising:
[0034] Lower shell 1, with positioning pin 2 installed inside;
[0035] Circuit board 3 is arranged inside the lower shell 1 and has through holes 4 that mate with the positioning pin 2.
[0036] The upper shell 5 is assembled onto the lower shell 1, and the positioning pin 2 abuts against the inner wall of the upper shell 5;
[0037] The first buckle 6 is arranged on the side of the lower shell 1, and the hook on it faces the side wall perpendicular to the lower shell 1. It is engaged with the first buckle block 7 on the side wall of the upper shell 5.
[0038] The second buckle 8 is located on the upper shell 5 and on the side of the first buckle 6. Its hook faces parallel to the side wall of the upper shell 5 and is engaged with the second buckle block 9 on the side wall of the lower shell 1.
[0039] The inner wall of the lower shell 1 is provided with a plurality of first support columns 10, and the inner wall of the upper shell 5 is provided with a plurality of second support columns 12. The first support columns 10 and the second support columns 12 respectively abut against the two ends of the positioning holes 11 on the circuit board 3.
[0040] Two first locking blocks 7 are spaced apart along the height direction of the inner wall of the upper shell 5, and the hooks of the first buckles 6 abut against the opposite surfaces of the two first locking blocks 7. Two second locking blocks 9 are spaced apart along the height direction of the inner wall of the lower shell 1, and the hooks of the second buckles 8 abut against the opposite surfaces of the two second locking blocks 9. This further improves the locking strength between the buckles and the locking blocks.
[0041] In one embodiment, the buckle and the lower shell 1 and / or upper shell 5 of the transformer adopt a sliding design. The inner wall of the lower shell 1 is provided with a mounting box 13, and the first buckle 6 is vertically slidably connected in the movable groove 14 of the mounting box 13. An elastic element 15 is provided between the first buckle 6 and the movable groove 14. This allows the buckle protruding from the shell surface to be retracted into the shell when the upper and lower shells are stored separately, facilitating storage, preventing the buckle from being damaged by impact, and, in conjunction with the use of the elastic element 15, achieving elastic pre-tightening when the buckle and the locking block are engaged, improving the closing strength of the upper and lower shells of the transformer.
[0042] The assembly process of a collision-preventing transformer structure in this embodiment includes: This transformer structure uses two buckles with different orientations to achieve more stable opening and closing guidance for the upper and lower shells, preventing lateral displacement of the upper and lower shells during assembly and disassembly, which could lead to collisions between the shell and its internal circuit board 3 and components. During assembly, the circuit board 3 is placed into the lower shell 1, the positioning pin 2 is inserted into the through hole 4, and the first support column 10 abuts against the positioning hole 11, completing the initial positioning of the circuit board 3; the lower shell 1 and the upper shell 5 are aligned and pressed together, the two buckles initially engage and guide, and then are pressed further in. The second buckle 8 slides along the surface of the mounting box 13, and the first buckle slides along the inner wall of the upper shell 5 until the two buckles engage with the corresponding blocks. At this point, the positioning pin 2 abuts against the inner wall of the upper shell 5, and the second support column 12 abuts against the positioning hole 11, thus completing the assembly of the transformer structure. This design facilitates personnel operation and improves work efficiency.
