Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer structure with a compact control board. Background Technology

[0002] Small transformers mounted on compact control boards are typically used for voltage conversion or signal isolation, and their compact design is adapted to fit limited space.

[0003] Chinese patent disclosure CN217933383U discloses a transformer output structure, which includes "a bracket, the front end of which has a through slot, the left and right ends of which each have a through slot communicating with the inside of the device slot, the left and right ends of which are movably connected to mounting structures, the two mounting structures being located in the two through slots respectively, and the opposing surfaces of the two mounting structures being threadedly connected to a cable routing structure, the lower end of which has a set of inlet holes, and the upper end of which has a set of outlet holes." This transformer output structure is achieved through... The wiring structure arranges the lines in a straight line inside the device slot. Due to the compact structure of the transformer when it is installed between the transformer and the control board, it may not be possible to directly connect the lines in a straight line. Therefore, the lines need to be pulled at an angle to the position of the electronic components to be connected. However, with traditional transformers, the lines are more likely to stick to the transformer surface after being pulled at an angle, which will affect the life of the lines. Furthermore, when the lines at different positions of the transformer are directly connected at an angle, it may cause the lines and transformer interfaces to be in a state of mutual wear and bending, which will lead to damage and bending of the lines. Utility Model Content

[0004] The purpose of this utility model is to provide a compact transformer structure for an electronic control board, which solves the problems in related technologies where traditional transformers are prone to contact between the lines and the transformer surface after the lines are pulled at an angle, which affects the lifespan of the lines. Furthermore, when the lines at different positions of the transformer are directly connected at an angle, the interface between the lines and the transformer may be in a state of mutual wear and bending, which may lead to damage and bending of the lines.

[0005] The technical solution of this utility model is as follows:

[0006] A transformer structure for a compact electronic control board includes a transformer body. Both ends of the transformer body are fixedly mounted with lines for connecting electronic components. Multiple protective rods for limiting the position of the lines are fixedly mounted on both sides of the transformer body. A limiting frame for limiting the position of the lines is slidably connected to the outer sides of the multiple protective rods. A frame door for closing the limiting frame is rotatably connected to one side of the limiting frame. A fixing buckle for fixing the lines is provided on the inner wall of the frame door. An adjusting screw for adjusting the displacement of the fixing buckle is rotatably connected to the outer side of the fixing buckle. The outer side of the adjusting screw is threadedly connected to the inner wall of the frame door.

[0007] Preferably, two limiting posts are fixedly installed on the inner wall of the other side of the limiting frame, and the outer sides of the two limiting posts are slidably connected to the inner wall of the protective rod.

[0008] Preferably, the top of the limiting frame is threadedly connected to a positioning screw, and the outer side of the positioning screw is threadedly connected to the inner side wall of the limiting post.

[0009] Preferably, the top inner wall of the protective rod is provided with multiple positioning screw holes, and the bottom outer side of the positioning screw is threadedly connected to the positioning screw holes.

[0010] Preferably, a connecting buckle is fixedly installed on the other side of the frame door, and the outer side of the connecting buckle is movably connected to the inner sidewall of the limiting frame.

[0011] Preferably, two limiting rods are fixedly installed on the outer side of the fixing buckle, and the outer sides of the two limiting rods are slidably connected to the inner sidewall of the limiting frame.

[0012] Preferably, an operating plate is fixedly installed at one end of the adjusting screw and the top end of the positioning screw.

[0013] Preferably, the fixing buckle is semi-circular.

[0014] The beneficial effects of this utility model are:

[0015] The limiting frame allows the wire that needs to be pulled diagonally to be placed inside. Then, based on the required diagonal movement position of the wire, the limiting frame drives the wire to slide on the protective rod. The wire can slide within the limiting frame according to the distance between each pair of limiting frames. This allows the limiting frame to fix the path of the wire during diagonal or straight pulling, preventing uncertainty in the wire's position that could cause it to come into contact with the transformer and affect its lifespan. After the limiting frame and wire have moved to the appropriate position, they can be fixed together using a fixing buckle. The limiting frame can also be fixed to the protective rod using a positioning screw, effectively preventing damage to the wire due to randomness in its position and preventing the impact of right-angle bends on the wire.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This embodiment proposes a compact transformer structure for an electronic control board, including a transformer body 1. Both ends of the transformer body 1 are fixedly mounted with lines 2 for connecting electronic components. Multiple protective rods 3 for protection and limiting are fixedly mounted on both sides of the transformer body 1. A limiting frame 4 for limiting the position of the lines 2 is slidably connected to the outer side of the multiple protective rods 3. A frame door 5 for closing the limiting frame 4 is rotatably connected to one side of the limiting frame 4. A fixing buckle 6 for fixing the lines 2 is provided on the inner wall of the frame door 5. An adjusting screw 61 for adjusting the displacement of the fixing buckle 6 is rotatably connected to the outer side of the fixing buckle 6. The outer side of the adjusting screw 61 is threadedly connected to the inner wall of the frame door 5. The fixing buckle 6 is semi-arc-shaped. When the lines 2 of the transformer body 1 need to be connected to other electronic components, the lines 2 can be placed inside the limiting frame 4 according to the required number and the function of the fixed-position limiting frame 4, and the frame door 5 is fitted against the limiting frame 4, thus securing the limiting frame 4. The limit frame 4 is closed to prevent the line 2 from detaching from the inside when it slides on the protective rod 3. When the limit frame 4 slides to the appropriate position of the line 2, the line 2 slides inside the limit frame 4 according to the distance between the two limit frames 4. This reduces the damage caused by the uncertainty of the position of the line 2 to other electronic components or the transformer body 1. The limit frame 4, which is closest to the interface between the line 2 and the transformer, can effectively reduce the bending caused by the direct bending between the line 2 and the transformer body 1, thereby further protecting the line 2. After the line 2 and the limit frame 4 are moved to the appropriate position, the adjusting screw 61 on the frame door 5 can be driven to make the adjusting screw 61 drive the fixing buckle 6 to slide outward from the inside of the frame door 5 and fit against the surface of the line 2. This fixes the line 2 inside the limit frame 4, while the limit frame 4 is fixed in position with the protective rod 3, which improves the overall protection of the line 2 by the transformer structure.

[0025] Please see Figure 3 , Figure 4 as well as Figure 5This embodiment proposes a compact transformer structure for an electronic control board. Two limiting posts 41 are fixedly installed on the inner wall of the other side of the limiting frame 4. The outer sides of the two limiting posts 41 are slidably connected to the inner wall of the protective rod 3. A positioning screw 42 is threadedly connected to the top of the limiting frame 4. The outer side of the positioning screw 42 is threadedly connected to the inner wall of the limiting posts 41. Multiple positioning screw holes 31 are provided on the top inner wall of the protective rod 3. The outer side of the bottom end of the positioning screw 42 is threadedly connected to the positioning screw holes 31. The limiting frame 4 prevents separation from the protective rod 3 by sliding the two limiting posts 41 on the inner wall of the protective rod 3. After the limiting frame 4 moves to a suitable position, the positioning screw 42 can be driven to slide downwards while the limiting posts 41 rotate, inserting into the corresponding positioning screw hole 31, thus fixing the limiting frame 4 in the appropriate position of the protective rod 3. A connecting buckle 51 is fixedly installed on the other side of the frame door 5. The outer side of the connecting buckle 51 is connected to the inner wall of the limiting frame 4. The inner wall of the frame is movable. When the frame door 5 and the limiting frame 4 are fitted together, the connecting buckle 51 can be inserted into the limiting frame 4 and fixed thereto. When the frame door 5 needs to open the limiting frame 4, the connecting buckle 51 can be pushed into the limiting frame 4, so that the frame door 5 can move the connecting buckle 51 out from the limiting frame 4 and open the frame door 5. Two limiting rods 62 are fixedly installed on the outer side of the fixing buckle 6. The outer side of the two limiting rods 62 is slidably connected to the inner wall of the limiting frame 4. As the adjusting screw 61 is driven to fit against the outside of the line 2, the fixing buckle 6 drives the limiting rod 62 to slide outward in sync. This allows the adjusting screw 61 to rotate on the fixing buckle 6 while the fixing buckle 6 remains in the same direction and close to the outside of the line 2. An operating plate 7 is fixedly installed on one end of the adjusting screw 61 and the top of the positioning screw 42. The adjusting screw 61 and the positioning screw 42 can be driven by rotating the operating plate 7 on them, which allows them to rotate on the frame door 5 and the limiting frame 4.

[0026] In this embodiment, during use, the wire 2 that needs to be pulled diagonally can first be placed inside the limiting frame 4. Then, according to the position where the wire 2 needs to move diagonally, the limiting frame 4 drives the wire 2 to slide on the protective rod 3. The wire 2 can slide inside the limiting frame 4 according to the distance between the two limiting frames 4. Thus, the path of the wire 2 in the diagonal or straight pulling state can be fixed by the limiting frame 4, which can effectively prevent the randomness of the position of the wire 2 from causing damage to the wire 2, and prevent the wire 2 from being affected by right-angle bending. After the limiting frame 4 and the wire 2 have moved to the appropriate position, the fixing buckle 6 can be driven by the adjusting screw 61, so that the fixing buckle 6 can fix the wire 2 inside the limiting frame 4. The limiting frame 4 can be fixed on the protective rod 3 by rotating the positioning screw 42 and inserting it into the positioning screw hole 31.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
