Description
Technical Field
[0001] This utility model relates to the field of patch transformer wire frame technology, specifically a patch transformer wire frame with a wound hollow heat dissipation structure. Background Technology
[0002] The wire-wound, hollowed-out heat dissipation structure of a surface-mount transformer (SMT) is a support structure for SMT transformers with hollowed-out heat dissipation function. It is a support structure specifically designed for SMT transformers, combining wire winding fixation and efficient heat dissipation. The wire frame is the installation skeleton of the transformer, used to support the windings and magnetic core, ensuring electrical insulation and mechanical stability. The wire-wound design achieves electromagnetic induction through precision winding of copper wire, while the hollowed-out wire frame optimizes the heat dissipation path of the windings, making it particularly suitable for high-frequency, high-power-density scenarios.
[0003] Based on existing solutions and actual production and processing, the current wire-wound hollow heat dissipation structure of the surface mount transformer wire frame still has some problems, such as: the pins on the surface mount transformer wire frame are fixedly installed on the transformer wire frame, which leads to poor pin alignment with different types of circuit boards, resulting in poor adaptability during use. Therefore, this utility model provides a wire-wound hollow heat dissipation structure of the surface mount transformer wire frame to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a surface mount transformer lead frame with a wound, hollow heat dissipation structure, in order to solve the problem mentioned in the background art that the pins on the surface mount transformer lead frame are fixedly mounted on the transformer lead frame, which leads to poor pin alignment with different types of circuit boards, resulting in poor adaptability during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire-wound hollow heat dissipation structure for a patch transformer wire frame, including a mounting frame with wire grooves on its upper surface;
[0006] Also includes:
[0007] A winding post is set inside the mounting frame, and a fixing block is fixedly installed on the outer side of the winding post. A movable structure is set in the middle of the winding post, and the movable structure includes a movable plate and a limiting rod. The movable plate is set in the middle of the winding post, and the limiting rod is connected to the rear side of the movable plate.
[0008] The pin is fixedly mounted on the upper end of the mounting frame, and the mounting frame is provided with a limit structure inside. The limit structure includes a spring, a moving rod and a mounting connecting rod. The spring is located inside the mounting frame, the moving rod is fixedly mounted on the inner side of the spring, and the mounting connecting rod is connected to the outer side of the middle part of the mounting frame.
[0009] Preferably, a mounting plate is movably mounted on the lower outer side of the mounting frame, and a mounting rod is connected to the upper outer side of the mounting plate. A connecting mounting block is fixedly mounted on the inner middle side of the mounting frame, and a connecting spring is provided on the upper outer side of the connecting mounting block.
[0010] Preferably, a fixed base plate is also fixedly installed at the lower end of the mounting plate, and a connecting fixing rod is movably installed on the outer side of the fixed base plate.
[0011] Preferably, the mounting rod and the mounting plate are connected by a thread and the rod also serves to limit the movement of the mounting frame.
[0012] Preferably, the movable plate and the winding post are slidably connected, and a protrusion structure is provided on the left side of the front end of the movable plate.
[0013] Preferably, the connecting spring and the mounting frame are connected by a snap-fit connection, and the connecting springs are symmetrically distributed about the center line of the connecting mounting block.
[0014] Preferably, the movable rod and the mounting frame are connected by a telescopic sliding connection, and the movable rod is symmetrically distributed about the center line of the fixed block.
[0015] Preferably, the fixing block and the moving rod are engaged, and the fixing block and the mounting connecting rod are threaded.
[0016] Compared with the prior art, the beneficial effects of this utility model are: the patch transformer wire frame with the wound hollow heat dissipation structure is provided with a movable structure, which can adjust the winding column, thereby aligning different types of circuit boards, and is provided with a limiting structure, which can limit the distance between the mounting frame and the winding column, thereby assembling the transformer wire frame.
[0017] By placing the mounting frame on the outside of the winding post, the mounting frame slides inward from the outside of the fixing block. This causes the fixing block to push the moving rod to slide outward from the inside of the mounting frame. The moving rod then compresses the spring, causing the fixing block to engage in the middle of the mounting frame. The spring then drives the moving rod to slide inward, causing the moving rod to engage in the outside of the fixing block. Rotating the mounting connecting rod causes it to be threaded on the outside of the middle of the mounting frame. This causes the mounting connecting rod to move inward, and finally to be threaded in the middle of the fixing block. This facilitates the assembly of the mounting frame and the winding post.
[0018] By rotating the limiting rod, it is threaded onto the rear side of the winding post, causing the limiting rod to move backward and separate from the rear side of the moving plate. Then, the winding post is pulled to the right, causing the moving plate to slide to the right inside the winding post to a suitable position. Rotating the limiting rod again causes it to be threaded onto the rear side of the winding post, causing it to move forward and threaded onto the rear side of the moving plate. This facilitates adjustment of the distance between the mounting frames, which in turn facilitates adjustment of the distance between the pins, and thus facilitates alignment of different types of circuit boards.
[0019] By rotating the connecting fixing rod, the connecting fixing rod is threaded on the outside of the fixed base plate, thus making the connecting fixing rod threaded in the appropriate position. The mounting frame is then snapped into place inside the mounting plate, and on the outside of the connecting mounting block, thus making the mounting frame snapped into place outside the connecting spring. Rotating the mounting rod, the mounting rod is threaded on the upper outer side of the mounting plate, thus moving the mounting rod inward, and finally making the mounting rod threaded on the lower outer side of the mounting frame, facilitating the fixing of the mounting frame.

[0027] 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.
[0028] Please see Figure 1-6 This utility model provides a technical solution: a wire frame for a surface-mount transformer with a wound, hollow heat dissipation structure, comprising: a mounting frame 1, a winding post 2, a mounting plate 3, a fixed base plate 4, a connecting fixing rod 5, a mounting rod 6, a movable plate 7, a wire groove 8, pins 9, a connecting mounting block 10, a connecting spring 11, a spring 12, a movable rod 13, a fixing block 14, a mounting connecting rod 15, and a limiting rod 16. In operation, the specific details are as follows... Figure 1 , Figure 3 and Figure 4 As shown, a spring 12 is fixedly installed inside the middle of the mounting frame 1, a movable rod 13 is movably installed inside the spring 12, a fixed block 14 is movably installed inside the movable rod 13, a mounting connecting rod 15 is movably installed outside the fixed block 14, and a winding post 2 is fixedly installed inside the fixed block 14. The mounting frame 1 is manually installed on the outside of the winding post 2, causing the mounting frame 1 to slide inward from the outside of the winding post 2. This causes the fixed block 14 to push the movable rod 13 to slide outward inside the mounting frame 1, which in turn causes the movable rod 13 to compress the spring 12, thus compressing the fixed block 14 within the mounting frame 1. The internal mechanism is engaged, and under the elastic action of the spring 12, the spring 12 drives the moving rod 13 to slide inward, thereby engaging the moving rod 13 with the outer side of the middle part of the fixing block 14. Tightening the mounting connecting rod 15 causes the mounting connecting rod 15 to be threaded on the outer side of the middle part of the mounting frame 1. Under the thread action between the mounting connecting rod 15 and the mounting frame 1, the mounting connecting rod 15 moves inward, thereby threading the mounting connecting rod 15 with the outer side of the fixing block 14, which facilitates the assembly between the mounting frame 1 and the winding post 2.
[0029] Specific examples Figure 1 , Figure 2 and Figure 4As shown, a mounting plate 3 is movably mounted on the lower outer side of the mounting frame 1, a fixed base plate 4 is fixedly mounted on the lower end of the mounting plate 3, a connecting mounting block 10 is fixedly disposed inside the mounting plate 3, a connecting spring piece 11 is fixedly mounted on the upper outer side of the connecting mounting block 10, and a mounting rod 6 is movably mounted on the upper outer side of the mounting plate 3. The mounting frame 1 is placed on the upper side of the mounting plate 3, causing the mounting frame 1 to slide downwards inside the mounting plate 3. This causes the mounting frame 1 to push the connecting spring piece 11 to compress, thereby causing the mounting frame 1 to slide downwards on the outer side of the connecting mounting block 10. The movement causes the mounting frame 1 to engage with the outer side of the connecting mounting block 10, thereby causing the connecting spring 11 to engage with the lower inner side of the mounting frame 1 under the elastic action of the connecting spring 11. Tightening the mounting rod 6 installed on the outer side of the upper end of the mounting plate 3 causes the mounting rod 6 to be threaded on the outer side of the upper end of the mounting plate 3 under the tightening action. Thus, under the thread action between the mounting rod 6 and the mounting plate 3, the mounting rod 6 moves inward, thereby causing the mounting rod 6 to be threaded on the outer side of the lower end of the mounting frame 1, which facilitates the installation of the mounting frame 1.
[0030] Specific examples Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a connecting fixing rod 5 is movably installed on the outer side of the fixed base plate 4, a movable plate 7 is set on the inner side of the winding post 2, and a limiting rod 16 is movably installed at the rear end of the movable plate 7. Tightening the limiting rod 16 causes the limiting rod 16 to be threadedly connected to the rear end of the winding post 2, thereby causing the limiting rod 16 to move backward and separate from the rear side of the movable plate 7. Then, manually pulling the mounting frame 1 to the right causes the mounting frame 1 to slide the winding post 2 outward under the pulling force, thereby causing the movable plate 7 to slide outward from the inside of the winding post 2 to a suitable position. After that, tightening the limiting rod 16 causes the limiting rod 16 to be threadedly connected to the rear end of the winding post 2, thereby causing the limiting rod 16 to be threadedly connected to the rear end of the winding post 2. 16 moves forward, causing the limiting rod 16 to be threaded on the rear side of the moving plate 7, causing the mounting frame 1 to slide the mounting plate 3 outward, and thus the mounting plate 3 to slide the fixed base plate 4 outward to a suitable position, which facilitates the adjustment of the distance between the pins 9, and facilitates the alignment of different types of circuit boards. Tightening the connecting fixing rod 5 causes the connecting fixing rod 5 to be threaded on the outside of the fixed base plate 4, which causes the connecting fixing rod 5 to move downward, and thus the connecting fixing rod 5 to be threaded in a suitable position, which facilitates the limiting of the mounting plate 3. Then, the wire groove 8 opened on the upper surface of the mounting frame 1 facilitates the passage of the wire group.
