Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and specifically relates to a transformer winding mold. Background Art

[0002] A transformer consists of an iron core and coils. The coils have two or more windings. Among them, the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. It can transform AC voltage, current, and impedance. Transformer coils are mostly wound using a winding mold, and after winding, they are wrapped with insulating tape.

[0003] The transformer winding mold with the publication number CN220963035U includes a mounting block. Baffles are connected to the outside of the first module and the second module, and a limiting mechanism is arranged inside the baffles. For this transformer winding mold, the mounting block is rectangular, and the mounting holes are rectangular, so the mold is more stable when connected to other equipment and will not rotate. The electric push rods are located around the mounting block, and the first module and the second module are connected to the outside of the electric push rods. The first module and the second module can be driven by the electric push rods to move away from or close to each other, so as to facilitate demolding. The baffles are located at both ends of the first module and the second module to prevent the wire from deviating out of the first module and the second module. A limiting mechanism is arranged inside the baffles. The limiting mechanism is located inside the baffle of the first module to prevent the head and tail ends of the wire from loosening. In addition, the existing winding molds also have the following disadvantages in use:

[0004] (1) The existing winding mold uses eight electric push rods to push the first module and the second module respectively to achieve expansion and contraction. Although the structure is simple, it greatly increases the energy consumption and leads to an increase in operating costs.

[0005] (2) The existing winding mold uses a spring to push the limiting plate to complete the limiting of the coil end. Since the coil must be tightened during winding to prevent it from loosening, the pushing force of the spring cannot meet the function of fixing the coil end of multiple turns of winding, thus reducing the stability of the coil end fixing.
