Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a long service life. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization.

[0003] For example, patent No. CN217239214U, the utility model discloses a small transformer, which relates to the field of transformer technology, including a first shell, a second shell is arranged on the side end of the first shell, the first shell and the second shell are jointly connected with a quick installation component, three groups of frames are arranged inside the first shell and the second shell, the top end of one group of frames is connected with an anti-drop component, and the plug plate at the side end of the second shell is inserted into the limit groove. When the first shell contacts the second shell, the spring pushes the plug block upward to form a fixation. When disassembling, unscrew the safety bolt, press the button downward, so that the top plate pushes the plug block downward, and then pull out the second shell to complete the disassembly. This design is relatively fast to install and disassemble. By pulling the half-threaded column outward, the slider slides in the slide groove, and then the wire is placed in the other half-threaded column, pushing the half-threaded column back to the initial position, and then the nut is screwed on the outside of the threaded column to prevent the wire from falling off easily.
