Description

Technical Field

[0001] This utility model relates to the field of transformer frame technology, and in particular to a high-strength multi-winding transformer frame. Background Technology

[0002] A transformer is a magnetic device that uses the principle of electromagnetic induction to transfer energy. It is an indispensable component in high-frequency switching power supplies. It mainly consists of a transformer frame, a magnetic core, and windings made of wires, metal sheets, or PCBs. The transformer frame plays the following roles in the transformer:

[0003] 1. To provide space for the copper wires in the transformer to be wound;

[0004] 2. Fix the magnetic core in the transformer;

[0005] 3. The slots in the frame provide a path for the wires to pass through during the winding process in transformer manufacturing;

[0006] 4. The metal pins in the frame are the supports for the copper wire winding of the transformer. After being soldered, they are connected to the PCB board and play a role in conducting electricity when the transformer is working.

[0007] 5. The protrusions, concave points, or chamfers in the frame can determine the placement direction or pin sequence of the transformer during use.

[0008] Currently, conventional transformer frames are divided into I-shaped and king-shaped designs, with relatively fixed designs. Transformer frames are often made as a single piece, requiring adjustments based on customer needs, which makes the processing steps quite complicated. In addition, the magnetic core in existing transformers is placed directly inside the frame, so when producing the magnetic core and frame, the size of the magnetic core needs to match the size of the frame, which is rather rigid.

[0009] Therefore, those skilled in the art have provided a high-strength multi-winding transformer frame to solve the problems mentioned in the background art. Utility Model Content

[0010] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength multi-winding transformer frame. Through a specially designed fixing mechanism, it allows for switching between I-shaped and T-shaped frames to meet different needs. The fixing method is quick and easy to install. Furthermore, a clamping mechanism allows for the fixation of magnetic cores of different shapes inside the frame, eliminating the need to manufacture specific magnetic cores tailored to the frame, thus improving the device's practicality.

[0011] To achieve the above objectives, the present invention provides the following technical solution:

[0012] A high-strength multi-winding transformer frame includes an upper fixing plate, a lower fixing plate, a first winding slot and a second winding slot. The bottom end of the lower fixing plate is provided with a clamping mechanism, and the outer walls of the first winding slot and the second winding slot are provided with fixing mechanisms.

[0013] The fixing mechanism includes a fixing ring. First sliding grooves are provided on both sides of the bottom end of the upper fixing plate. A first pull plate is provided inside the first sliding groove. A first locking rod is provided on one side of the outer wall of the first pull plate. A second spring is sleeved on the outer wall of one end of the first locking rod. A first locking plate is provided at the upper end of the first winding groove. Second locking grooves are provided on both sides of the outer wall of the first locking plate at positions corresponding to the first locking rod. The second locking grooves and the first locking rod cooperate with each other. A winding partition is provided at the lower end of the first winding groove. Second sliding grooves are provided on both sides of the bottom end of the winding partition. A second pull plate is provided inside the second sliding groove. The second plate has a second locking rod on one side of its outer wall, a third spring on one end of its outer wall, a second locking plate on the upper end of its winding groove, and third slots on both sides of its outer wall. The third slots and the second locking rod cooperate with each other. The fixing ring has fixing rods on both sides of its bottom end, a first slot on one side of its lower outer wall, and the fixing rods pass through the upper fixing plate and the lower fixing plate. Pull rods pass through both sides of the lower fixing plate, and a first spring is provided on one end of the pull rod. The pull rods and the first slots cooperate with each other.

[0014] The above technical solution, through its fixed mechanism, allows for switching between I-shaped and T-shaped frames to meet different needs. Furthermore, the fixing method is quick and allows for rapid installation.

[0015] Furthermore, the clamping mechanism includes a fixed block, a rotating rod is provided through one side of the outer wall of the fixed block, a second bevel gear is provided on the outer wall of one end of the fixed block, the second bevel gear is meshed with a first bevel gear, a threaded rod is provided on one side of the outer wall of the first bevel gear, a slider is threadedly sleeved on the outer wall of the threaded rod, and the upper end of the slider passes through the lower fixed plate and is connected to an arc-shaped clamping plate.

[0016] The above technical solution, through the clamping mechanism, allows magnetic cores of different shapes to be fixed inside the frame, eliminating the need to manufacture corresponding magnetic cores according to the frame, thus improving the practicality of the device.

[0017] Furthermore, a fixing cap is threadedly connected to the upper end of the upper fixing plate;

[0018] The above technical solution facilitates the fixing of the upper end of the magnetic core.

[0019] Furthermore, a knob is provided on the outer wall of one end of the rotating rod;

[0020] The above technical solution facilitates the control of the clamping mechanism.

[0021] Furthermore, lead wire grooves are provided on both sides of the outer wall of the lower fixing plate, and pins are provided at the bottom end of the lower fixing plate at the position corresponding to the lead wire grooves;

[0022] The above technical solution facilitates the wiring and fixing of the wires.

[0024] The above technical solution facilitates cable routing.

[0025] Furthermore, the upper fixing plate and the lower fixing plate are made of tin-plated flame-retardant nylon.

[0026] The above technical solutions improve the practicality of the skeleton.

[0027] Furthermore, the first and second winding grooves are made of conductive polymer materials;

[0028] Through the above technical solutions, conductive polymer materials have excellent dielectric properties and are lightweight, reducing the weight of the skeleton.

[0029] This utility model has the following beneficial effects:

[0030] 1. The present invention proposes a high-strength multi-winding transformer frame. By pulling the second pull plate, the second locking rod moves outward, thereby disengaging from the second locking plate and removing the lower fixing plate. Then, by pulling the first pull plate, the first locking rod is pulled out of the second locking groove, allowing the first winding groove to be removed. This allows for switching between I-shaped and T-shaped frames according to different customer needs, greatly improving the practicality of the device.

[0031] 2. This utility model proposes a high-strength multi-winding transformer frame. By rotating a knob, the rotating rod rotates, which in turn drives the first bevel gear, which is meshed with the second bevel gear, to rotate. This causes the threaded rod to rotate, which in turn causes the slider to move the arc-shaped clamping plate, thus fixing the magnetic core at the bottom. By fixing the magnetic core, problems with the transformer during use due to magnetic core position deviation can be avoided. At the same time, the clamping mechanism can fix magnetic cores of different shapes inside the frame, eliminating the need to specially manufacture magnetic cores according to the frame, thus improving the practicality of the device.
